===================================
-Open-iSCSI persistent configuration is implemented as a DBM database

+Open-iSCSI persistent configuration is stored in a number of

+format. This configuration root directory is /etc/iscsi by default,
+but may also commonly be in /var/lib/iscsi.
-The database contains two tables:
+Configuration is contained in directories for:
-- Discovery table (/etc/iscsi/send_targets);
-- Node table (/etc/iscsi/nodes).
-
-The regular place for iSCSI database files: /etc/iscsi/nodes

-linux-iscsi for Debian
------------------------------------
-
-The linux-iscsi package contains the userspace portion the Linux iSCSI project.
-It has a dependency on the linux-iscsi-modules package, which needs to be built from the linux-iscsi-modules-source against the specific kernel version running
-on your system.
-
-Building
---------
-Modules cannot be built against the kernel-headers alone. You will need
-to extract and configure your kernel tree, then use the make-kpkg command
-(from the kernel-package package) to build a new kernel and modules.
-See the make-kpkg man page, particularly the modules-image section. The
-following example shows how to build the linux-iscsi-modules package; just
-substitute the appropriate version strings. Follow these instructions
-(as root) in order to build the linux-iscsi-modules package for your kernel:
-
-dpkg -i linux-iscsi-modules-source_5.0.0.0.3rc6-363_all.deb
-cd /usr/src
-rm -rf modules/linux-iscsi
-tar jxpvf linux-iscsi-modules-source.tar.bz2
-cd linux-2.6.11.11 (or your appropriate version)
-make-kpkg --added-modules linux-iscsi modules-image
-
-By default, make-kpkg will assume /usr/src/linux-iscsi-modules-source.tar.bz2
-has been extracted under /usr/src. However, that also requires building as
-root. If you want to do the build as a non-root user, you need to use the
-MODULE_LOC environment variable. For example:
-
-cd ~/builds
-export MODULES_LOC=$PWD/modules
-tar jxpvf /usr/src/linux-iscsi-modules-source.tar.bz2
-cd ~/builds/linux-2.6.11.11 (or your appropriate version)
-make-kpkg --added-modules linux-iscsi modules-image
-
-Installing
-----------
-
-Once you have built the linux-iscsi-modules package, you can install the
-binaries:
-
-dpkg -i linux-iscsi_5.0.0.0.3rc6-363_i386.deb linux-iscsi-modules-2.6.11.11_5.0.0.0.3rc6-363+10.00.Custom_i386.deb

+Installation Instructions
+*************************
+
+Copyright (C) 1994, 1995, 1996, 1999, 2000, 2001, 2002, 2004, 2005,
+2006, 2007, 2008 Free Software Foundation, Inc.
+
+ This file is free documentation; the Free Software Foundation gives
+unlimited permission to copy, distribute and modify it.
+
+Basic Installation
+==================
+
+ Briefly, the shell commands `./configure; make; make install' should
+configure, build, and install this package. The following
+more-detailed instructions are generic; see the `README' file for
+instructions specific to this package.
+
+ The `configure' shell script attempts to guess correct values for
+various system-dependent variables used during compilation. It uses
+those values to create a `Makefile' in each directory of the package.
+It may also create one or more `.h' files containing system-dependent
+definitions. Finally, it creates a shell script `config.status' that
+you can run in the future to recreate the current configuration, and a
+file `config.log' containing compiler output (useful mainly for
+debugging `configure').
+
+ It can also use an optional file (typically called `config.cache'
+and enabled with `--cache-file=config.cache' or simply `-C') that saves
+the results of its tests to speed up reconfiguring. Caching is
+disabled by default to prevent problems with accidental use of stale
+cache files.
+
+ If you need to do unusual things to compile the package, please try
+to figure out how `configure' could check whether to do them, and mail
+diffs or instructions to the address given in the `README' so they can
+be considered for the next release. If you are using the cache, and at
+some point `config.cache' contains results you don't want to keep, you
+may remove or edit it.
+
+ The file `configure.ac' (or `configure.in') is used to create
+`configure' by a program called `autoconf'. You need `configure.ac' if
+you want to change it or regenerate `configure' using a newer version
+of `autoconf'.
+
+The simplest way to compile this package is:
+
+ 1. `cd' to the directory containing the package's source code and type
+ `./configure' to configure the package for your system.
+
+ Running `configure' might take a while. While running, it prints
+ some messages telling which features it is checking for.
+
+ 2. Type `make' to compile the package.
+
+ 3. Optionally, type `make check' to run any self-tests that come with
+ the package.
+
+ 4. Type `make install' to install the programs and any data files and
+ documentation.
+
+ 5. You can remove the program binaries and object files from the
+ source code directory by typing `make clean'. To also remove the
+ files that `configure' created (so you can compile the package for
+ a different kind of computer), type `make distclean'. There is
+ also a `make maintainer-clean' target, but that is intended mainly
+ for the package's developers. If you use it, you may have to get
+ all sorts of other programs in order to regenerate files that came
+ with the distribution.
+
+ 6. Often, you can also type `make uninstall' to remove the installed
+ files again.
+
+Compilers and Options
+=====================
+
+ Some systems require unusual options for compilation or linking that
+the `configure' script does not know about. Run `./configure --help'
+for details on some of the pertinent environment variables.
+
+ You can give `configure' initial values for configuration parameters
+by setting variables in the command line or in the environment. Here
+is an example:
+
+ ./configure CC=c99 CFLAGS=-g LIBS=-lposix
+
+ *Note Defining Variables::, for more details.
+
+Compiling For Multiple Architectures
+====================================
+
+ You can compile the package for more than one kind of computer at the
+same time, by placing the object files for each architecture in their
+own directory. To do this, you can use GNU `make'. `cd' to the
+directory where you want the object files and executables to go and run
+the `configure' script. `configure' automatically checks for the
+source code in the directory that `configure' is in and in `..'.
+
+ With a non-GNU `make', it is safer to compile the package for one
+architecture at a time in the source code directory. After you have
+installed the package for one architecture, use `make distclean' before
+reconfiguring for another architecture.
+
+ On MacOS X 10.5 and later systems, you can create libraries and
+executables that work on multiple system types--known as "fat" or
+"universal" binaries--by specifying multiple `-arch' options to the
+compiler but only a single `-arch' option to the preprocessor. Like
+this:
+
+ ./configure CC="gcc -arch i386 -arch x86_64 -arch ppc -arch ppc64" \
+ CXX="g++ -arch i386 -arch x86_64 -arch ppc -arch ppc64" \
+ CPP="gcc -E" CXXCPP="g++ -E"
+
+ This is not guaranteed to produce working output in all cases, you
+may have to build one architecture at a time and combine the results
+using the `lipo' tool if you have problems.
+
+Installation Names
+==================
+
+ By default, `make install' installs the package's commands under
+`/usr/local/bin', include files under `/usr/local/include', etc. You
+can specify an installation prefix other than `/usr/local' by giving
+`configure' the option `--prefix=PREFIX'.
+
+ You can specify separate installation prefixes for
+architecture-specific files and architecture-independent files. If you
+pass the option `--exec-prefix=PREFIX' to `configure', the package uses
+PREFIX as the prefix for installing programs and libraries.
+Documentation and other data files still use the regular prefix.
+
+ In addition, if you use an unusual directory layout you can give
+options like `--bindir=DIR' to specify different values for particular
+kinds of files. Run `configure --help' for a list of the directories
+you can set and what kinds of files go in them.
+
+ If the package supports it, you can cause programs to be installed
+with an extra prefix or suffix on their names by giving `configure' the
+option `--program-prefix=PREFIX' or `--program-suffix=SUFFIX'.
+
+Optional Features
+=================
+
+ Some packages pay attention to `--enable-FEATURE' options to
+`configure', where FEATURE indicates an optional part of the package.
+They may also pay attention to `--with-PACKAGE' options, where PACKAGE
+is something like `gnu-as' or `x' (for the X Window System). The
+`README' should mention any `--enable-' and `--with-' options that the
+package recognizes.
+
+ For packages that use the X Window System, `configure' can usually
+find the X include and library files automatically, but if it doesn't,
+you can use the `configure' options `--x-includes=DIR' and
+`--x-libraries=DIR' to specify their locations.
+
+Particular systems
+==================
+
+ On HP-UX, the default C compiler is not ANSI C compatible. If GNU
+CC is not installed, it is recommended to use the following options in
+order to use an ANSI C compiler:
+
+ ./configure CC="cc -Ae"
+
+and if that doesn't work, install pre-built binaries of GCC for HP-UX.
+
+ On OSF/1 a.k.a. Tru64, some versions of the default C compiler cannot
+parse its `<wchar.h>' header file. The option `-nodtk' can be used as
+a workaround. If GNU CC is not installed, it is therefore recommended
+to try
+
+ ./configure CC="cc"
+
+and if that doesn't work, try
+
+ ./configure CC="cc -nodtk"
+
+Specifying the System Type
+==========================
+
+ There may be some features `configure' cannot figure out
+automatically, but needs to determine by the type of machine the package
+will run on. Usually, assuming the package is built to be run on the
+_same_ architectures, `configure' can figure that out, but if it prints
+a message saying it cannot guess the machine type, give it the
+`--build=TYPE' option. TYPE can either be a short name for the system
+type, such as `sun4', or a canonical name which has the form:
+
+ CPU-COMPANY-SYSTEM
+
+where SYSTEM can have one of these forms:
+
+ OS KERNEL-OS
+
+ See the file `config.sub' for the possible values of each field. If
+`config.sub' isn't included in this package, then this package doesn't
+need to know the machine type.
+
+ If you are _building_ compiler tools for cross-compiling, you should
+use the option `--target=TYPE' to select the type of system they will
+produce code for.
+
+ If you want to _use_ a cross compiler, that generates code for a
+platform different from the build platform, you should specify the
+"host" platform (i.e., that on which the generated programs will
+eventually be run) with `--host=TYPE'.
+
+Sharing Defaults
+================
+
+ If you want to set default values for `configure' scripts to share,
+you can create a site shell script called `config.site' that gives
+default values for variables like `CC', `cache_file', and `prefix'.
+`configure' looks for `PREFIX/share/config.site' if it exists, then
+`PREFIX/etc/config.site' if it exists. Or, you can set the
+`CONFIG_SITE' environment variable to the location of the site script.
+A warning: not all `configure' scripts look for a site script.
+
+Defining Variables
+==================
+
+ Variables not defined in a site shell script can be set in the
+environment passed to `configure'. However, some packages may run
+configure again during the build, and the customized values of these
+variables may be lost. In order to avoid this problem, you should set
+them in the `configure' command line, using `VAR=value'. For example:
+
+ ./configure CC=/usr/local2/bin/gcc
+
+causes the specified `gcc' to be used as the C compiler (unless it is
+overridden in the site shell script).
+
+Unfortunately, this technique does not work for `CONFIG_SHELL' due to
+an Autoconf bug. Until the bug is fixed you can use this workaround:
+
+ CONFIG_SHELL=/bin/bash /bin/bash ./configure CONFIG_SHELL=/bin/bash
+
+`configure' Invocation
+======================
+
+ `configure' recognizes the following options to control how it
+operates.
+
+`--help'
+`-h'
+ Print a summary of all of the options to `configure', and exit.
+
+`--help=short'
+`--help=recursive'
+ Print a summary of the options unique to this package's
+ `configure', and exit. The `short' variant lists options used
+ only in the top level, while the `recursive' variant lists options
+ also present in any nested packages.
+
+`--version'
+`-V'
+ Print the version of Autoconf used to generate the `configure'
+ script, and exit.
+
+`--cache-file=FILE'
+ Enable the cache: use and save the results of the tests in FILE,
+ traditionally `config.cache'. FILE defaults to `/dev/null' to
+ disable caching.
+
+`--config-cache'
+`-C'
+ Alias for `--cache-file=config.cache'.
+
+`--quiet'
+`--silent'
+`-q'
+ Do not print messages saying which checks are being made. To
+ suppress all normal output, redirect it to `/dev/null' (any error
+ messages will still be shown).
+
+`--srcdir=DIR'
+ Look for the package's source code in directory DIR. Usually
+ `configure' can determine that directory automatically.
+
+`--prefix=DIR'
+ Use DIR as the installation prefix. *Note Installation Names::
+ for more details, including other options available for fine-tuning
+ the installation locations.
+
+`--no-create'
+`-n'
+ Run the configure checks, but stop before creating any output
+ files.
+
+`configure' also accepts some other, not widely useful, options. Run
+`configure --help' for more details.

+Iscsiuio Userspace Tool
+Version 0.7.8.2
+Dec 10, 2013
+------------------------------------------------------
+
+This tool is to be used in conjunction with the QLogic NetXtreme II Linux
+driver (Kernel module name: 'bnx2' and 'bnx2x'), QLogic CNIC driver,
+and the QLogic iSCSI driver (Kernel module name: 'bnx2i').
+This user space tool is used in conjunction with the following
+QLogic Network Controllers:
+ bnx2: BCM5706, BCM5708, BCM5709 devices
+ bnx2x: BCM57710, BCM57711, BCM57711E, BCM57712, BCM57712E,
+ BCM57800, BCM57810, BCM57840 devices
+
+This utility will provide the ARP and DHCP functionality for the iSCSI offload.
+The communication to the driver is done via Userspace I/O (Kernel module name
+'uio').
+
+There is one component to this application:
+
+1. 'iscsiuio' - This is the daemon which aids in creating iSCSI offloaded
+ connections.
+
+Dependencies:
+=======================================
+
+Linux Kernel Dependencies:
+1. QLogic CNIC driver (cnic)
+1. QLogic iSCSI offload driver (bnx2i)
+2. Userspace I/O driver (uio)
+
+Directory Structure of this Package:
+=======================================
+
+<root>
+ |
+ +-doc (documentation directory: man pages)
+ |
+ +-src
+ |
+ +- uip - the uIP stack
+ |
+ +- unix - iscsiuio source
+
+
+
+Compiling / Installing
+=======================================
+
+1. Please untar the tarball.
+2. Run the configure script. This will create the Makefiles and proper
+ header files needed for the build.
+3. Run 'make'. This will create the binary, 'iscsiuio'
+4. Run 'make install' to place the binaries in their installed location.
+ (The default location is '/sbin')
+
+iscsid IFACE Configuration File:
+=======================================
+The network interface configuration files are driven by the iscsid iface
+files. The configuration data is parsed by iscsid and passed to the uIP
+stack when the connection is established.
+
+One can use the following iscsiadm commands to create/set the configuration
+using the iface files:
+
+1. Create the iface file:
+
+ iscsiadm -m iface -I <iface name> --op=new
+
+2. Discover the targets associated with the new iface
+
+ iscsiadm -m discovery -t st -p <iSCSI target IP address> -I <iface name>
+
+3. Update the iface file:
+
+ To use a static IPv4 address:
+ iscsiadm -m iface -I <iface name> --op=update --name=iface.ipaddress --value=<static IPv4 address ie: 192.168.0.1>
+
+ To use a DHCP address:
+ iscsiadm -m iface -I <iface name> --op=update --name=iface.ipaddress --value=0.0.0.0
+
+ The following values are required.
+
+ To specify the bnx2i as the transport:
+ iscsiadm -m iface -I <iface name> --op=update --name=iface.transport_name --value=bnx2i
+
+ To specify the network interface to offload with:
+
+ a. Specify the physical network interface name <ie. eth0, eth1, eth2 ...>
+ iscsiadm -m iface -I <iface name> --op=update --name=iface.net_ifacename --value=<network interface name>
+
+ b. Specify the iSCSI MAC address of the iSCSI HBA
+ iscsiadm -m iface -I <iface name> --op=update --name=iface.hwaddress --value=<MAC address of the iSCSI HBA>
+
+4. Now all the settings should be set so that one could connect to their
+ desired iSCSI target.
+
+ iscsiadm -m node -p <iSCSI target IP address> -T <target name> -I <iface name> --login
+
+bnx2 Limitations:
+=======================================
+* RX iSCSI ring:
+ * default ring size is 3 entries
+ * default buffer size is 0x400 bytes
+* TX iSCSI ring:
+ * default ring size of 1 entry
+ * default buffer size is 0x400 bytes
+
+bnx2x Limitations:
+=======================================
+* RX iSCSI ring:
+ * default ring size is 15 entries
+ * default buffer size is 0x400 bytes
+* TX iSCSI ring:
+ * default ring size of 1 entry
+ * default buffer size is 0x400 bytes
+
+Other Limiations:
+
+Any packets larger then the buffer size will not be sent/received by the
+hardware and will be dropped.
+
+IPv6 support:
+
+IPv6 NDP (neighbor discovery protocol), DHCPv6 and Static IPv6 are now
+supported. The IPv6 address used for the connection will be matched against
+the DHCPv6/static IPv6 address, the RA (router advertise) address, and the
+assigned link local address.
+
+VLAN support:
+
+VLAN support is only supported when using static IP addresses.
+Also, currently only 1 VLAN is supported per physical network interface.
+Either non-VLAN offloaded traffic is allowed or VLAN offloaded traffic
+is allowed. The current implementation does not support both at the
+same time.
+
+Currently there is no explicit VLAN attributes in the iface file.
+To configure the VLAN offload, the iface.hwaddress attribute or
+physical net_ifacename (without the VLAN identifier) must be used
+to specify the HBA device. For the proper CNIC routing, the
+corresponding L2 interface which has the associated VLAN interface must
+have an IP address on the same subnet.
+
+The following attributes need to be filled when offloading via the
+VLAN interface:
+
+ iface.iscsi_ifacename = <name of this iface file>
+ iface.hwaddress = XX:XX:XX:XX:XX:XX
+ iface.ipaddress = XX.XX.XX.XX
+ iface.transport_name = bnx2i
+
+Setting IP address:
+
+On RHEL5.4, RHEL5.5+, RHEL6.0+, and SLES11SP1 distributions,
+discovery login is done over the Linux TCP/IP stack and L2 network
+interface. The ethx interface corresponding to the HBA must
+therefore be in the same IP subnet in order to reach the iSCSI
+target during discovery. However, the HBA's IP address should not
+be the same as the L2 ethx's IP address.
+
+Starting with RHEL6.1 and all other newer distributions, discovery
+using SendTargets is done over the HBA interface, so there is no
+need for the HBA and L2 network to be on the same subnet. However,
+if VLAN is used on the HBA, they still have to be on the same subnet
+as described above.
+
+
+Setting Netmask and Gateway addresses:
+
+With the current limitations of the iface file, there are no entries
+to allow the user to enter a netmask or gateway IP address.
+
+The only way to explicitly configure these options is to use DHCP
+addressing. Then the netmask/gateway are set on the DHCP server.
+These settings are then sent to uIP via the DHCPOFFERs.
+
+If the netmask is not defined then the netmask are automatically
+generated depending on the destination IP address.
+
+Debugging:
+=======================================
+
+By default, the iscsiuio daemon does not output any messages to the log file,
+'/var/log/iscsiuio.log'. Message logging is only enabled when the daemon is
+run under debug mode.
+
+To run the daemon in debug mode please pass the parameter '-d <debug level>'
+
+where the following debug levels are defined:
+
+DEBUG 4 - Print all messages
+INFO 3 - Print messages needed to follow the uIP code (default)
+WARN 2 - Print warning messages
+ERROR 1 - Only print critical errors
+
+A sample banner message:
+
+INFO [Mon Jun 20 11:23:14 2011]Started iSCSI uio stack: Ver 0.7.0.6
+INFO [Mon Jun 20 11:23:14 2011]Build date: Mon Jun 20 11:22:05 PDT 2011
+INFO [Mon Jun 20 11:23:14 2011]Debug mode enabled
+
+These messages can be used to help debug any issues.
+
+When debugging issues like the iscsid, the iscsiuio daemon can be run
+in the foreground and the maximum debugging level should be used.
+
+To place the daemon in foreground mode please pass the parameter '-f'
+
+Note: The messages to the log file are not flushed unless debugging is enabled.
+
+Note: If the daemon iscsiuio is running, one will not be able to
+ trample over the existing binary. One might see the following message:
+
+ 'cannot create regular file `/sbin/iscsiuio': Text file busy'
+
+ The solve this, please stop the iscsid service and then install.
+
+Warning: If full debug is enabled, this may quickly fill the partition
+containing the iscsiuio logs. This is because full debugging will log
+packet activity which on a busy network will quickly fill the logs.
+
+Note: If the bnx2i and cnic drivers are unloaded, then iscsiuio will also
+need to be restarted so that it can determine the iscsid version.

+ if there is a specific 1024 byte size broadcast
+ packet
+ Cause: This is another corner case where the packet size
+ is also exactly 1024 bytes + padding that exceeded
+ the DMA rx buffer. The previous fix was not
+ sufficient
+ Change: Ensure that the packet size + padding do not
+ exceed this limit.
+ Impact: 10G only. 1G already has the guard against it.

+ acquisition engine properly and to its entirety
+ Impact: IPv6 + VLAN using the network VLAN configuration
+ method
+
+ 2. Problem: Cont00065768 - RHEL5.X iscsiuio segfault possible
+ if there is a specific 1024 byte size broadcast

+ ------------
+ 1. Change: Enable HP SD mode
+ Impact: 577XX/578XX
+
+
+uIP v0.7.4.2j (Jul 18, 2012)
+=======================================================
+ Fixes
+ -----
+ 1. Problem: Cont00064665 - Linux iSCSI connects via gateway address
+ on the wrong subnet
+ Cause: The gateway address used was not checked against the
+ subnet mask specified before the ARP requests. Since
+ this behavior deters from how L2 operates, therefore,
+ a change was made to correct this.
+ Change: Added check of the gateway specified against the subnet
+ specified.
+ Impact: Static IPv4 operation
+
+ 2. Problem: Cont00064722 - Linux iSCSI unable to force IPv6 LL
+ override (advanced iface parameters)
+ Cause: The override LL address was not being populated to the
+ IPv6 address database correctly
+ Change: Added this correctly to the IPv6 initialization
+ Impact: Static/DHCP IPv6 LL address override only
+
+
+uIP v0.7.4.2i (Jul 11, 2012)
+=======================================================
+ Fixes
+ -----
+ 1. Problem: Cont00064604 - Fails to connect to routed IPv6 target

+ Impact: All
+
+
+uIP v0.7.4.2h (Jun 15, 2012)
+=======================================================
+ Fixes
+ -----
+ 1. Problem: Cont00063863 - can't boot into offload image
+ when VLAN is enabled
+ Cause: During the iSCSI login exchange, certain iSCSI targets
+ will send an ARP request even though the TCP connection
+ has been made. The bug was in this ARP reply where
+ the local MAC was corrupted when VLAN is enabled.
+ Change: Fixed the ARP reply packet
+ Impact: All
+
+
+uIP v0.7.4.2g (Jun 08, 2012)
+=======================================================
+ Fixes
+ -----
+ 1. Problem: Cont00063816 - The initiator is not able to connect
+ to the iSCSI targets over VLAN
+ Cause: The process packet routine did not consider the PCP
+ of the VLAN tag to be non-zero. This created a
+ mismatch when this VLAN tag was compared against the
+ nic_iface->vlan_id which doesn't include the PCP.
+ Change: Added the consideration of non-zero PCP
+ Impact: All
+
+
+uIP v0.7.4.2f (Jun 04, 2012)
+=======================================================
+ Fixes
+ -----
+ 1. Problem: Cont00063626 - Static IPv6 does not connect when
+ the prefix len is not set explicitly
+ Cause: The IPv6 prefix length was not set correctly
+ for Static IPv6 operation when CIDR notation is
+ not specified
+ Change: Fixed the default prefix length
+ Impact: Static IPv6
+
+ 2. Problem: Cont00063651 - Cannot connect to iSCSI targets
+ HP PTM/SF
+ Cause: Switch-Dependent mode + invalid Outer VLAN was
+ not supported
+ Change: Allow SD+invalid OV to fallback to SF operation mode
+ Impact: 5771X/578XX
+
+
+uIP v0.7.4.2e (May 30, 2012)
+=======================================================
+ Fixes
+ -----
+ 1. Problem: Cont00063443 - Compilation error on SLES11sp1
+ Cause: The iface_num field was not defined
+ Change: Fixed all references to iface_num
+ Impact: SLES11sp1
+
+ 2. Problem: Cont00063518 - HBA fails to connect across router
+ using iface.gateway address
+ Cause: The gateway override code did not populate the
+ address into the lower level engine
+ Change: Fixed the gateway override code
+ Impact: IPv4 Static IP operation
+
+ 3. Problem: Cont00063567 - IPv6 LL and RA override does not work
+ Cause: The IPv6 LL/RA override addresses were overwritten
+ by the NDP engine
+ Change: Fixed the LL/RA override code
+ Impact: IPv6 operation
+
+ Enhancements
+ ------------
+ 1. Added support for jumbo MTU (independent from the L2 MTU)
+
+
+uIP v0.7.4.2d (May 21, 2012)
+=======================================================
+ Fixes
+ -----
+ 1. Problem: Cont00063421 - Static IPv6 cannot connect via RA/LL
+ Cause: The router advertise and the linklocal address
+ were corrupted due to the override capabilities
+ added for the newer open-iscsi util
+ Change: Fixed the address override code
+ Impact: Static IPv6
+
+ Enhancements
+ ------------
+ 1. Allow VLAN tag = 1 (router management) to connect offload
+
+
+uIP v0.7.4.2c (May 09, 2012)
+=======================================================
+ Fixes
+ -----
+ 1. Problem: RHEL BZ 734010/804580 - issues found by the Coverity
+ scan
+ Cause: 10 code issues were flagged for revision
+ Change: Fixed all area of concern
+ Impact: All
+
+ 2. Problem: Cont00063177 - IPv4 DHCP with VLAN specification in
+ iface file gets wrong address
+ Cause: The DHCPv4 handler was not discriminating the VLAN tag
+ associated with the DHCP offers from multiple DHCP
+ servers
+ Change: Changed the DHCPv4 handler to drop DHCP offer packets
+ that doesn't match the VLAN tag of the intended DHCP
+ discovery packet
+ Impact: DHCPv4 operation
+
+
+uIP v0.7.4.2b (May 01, 2012)
+=======================================================
+ Fixes
+ -----
+ 1. Problem: Cont00062993 - IPv6 DHCP with VLAN specification in
+ iface file gets wrong address
+ Cause: The DHCPv6 request was using the same DUID as always
+ so the non-VLAN DHCP server responded to our broadcast
+ instead
+ Change: Changed the DHCPv6 request DUID to link address + time
+ instead of link address alone
+ Impact: DHCPv6 operation
+
+
+uIP v0.7.4.1j (Apr 24, 2012)
+=======================================================
+ Fixes
+ -----
+ 1. Problem: Cont00062805 - Cannot login to iSCSI targets on RHEL6.3
+ Cause: The problem was caused by a change made to the iface_rec
+ structure in the RHEL6.3 inbox open-iscsi util
+ Change: The new changes is now incorporated
+ Impact: All
+
+
+uIP v0.7.4.1i (Apr 16, 2012)
+=======================================================
+ Fixes
+ -----
+ 1. Problem: Cont00062660 - Unable to login with VLAN iscsiuio
+ on RHEL6.2
+ Cause: The open-iscsi util in RHEL6.2 has a bug which
+ does not pass the correct iface_num to iscsiuio
+ Change: Added workaround to fall back to do the legacy
+ VLAN support if iface_num and vlan_id = 0
+ Impact: RHEL6.2
+
+
+uIP v0.7.4.1h (Apr 13, 2012)
+=======================================================
+ Enhancements
+ ------------
+ 1. Added support for the new iface_num field in the iscsi_uevent
+ path
+
+ 2. Fixed bug in the nic_iface search engine based on iface_num
+
+
+uIP v0.7.4.1g (Mar 22, 2012)
+=======================================================
+ Fixes
+ -----
+ 1. Problem: Cont00061869 - Unable to setup an offload iSCSI
+ connection with FLR/NPAR under ESX5.0:PDA
+ Cause: The physical function ID was previously extracted
+ from the sysfs of the VM which might not be consistent
+ to the actual physical setup due to the function
+ remapping in the hypervisor
+ Change: Read the physical function ID directly from the BAR0
+ ME register
+ Impact: All
+
+ 2. Problem: Cont00062170 - IPv6 login/logout stress fails
+ Cause: The packet interrupt was lost after running the test
+ for a much longer period of time. A bug in the
+ packet processing routine was found to exit prematurely
+ Change: Fixed the packet processing routine to process all
+ packets before exiting
+ Impact: All
+
+
+uIP v0.7.4.1f (Mar 19, 2012)
+=======================================================
+ Fixes
+ -----
+ 1. Problem: Cont00062170 - IPv6 login/logout stress fails
+ Cause: The packet buffer routine for IPv6 did not take
+ network order <-> host order into consideration
+ Change: Added a htons call to compensate for the ntohs pair
+ Impact: All
+
+
+uIP v0.7.4.1e (Mar 08, 2012)
+=======================================================
+ Fixes
+ -----
+ 1. Problem: Cont00061978 - Load/unload stress test fails
+ Cause: The bnx2x open request was failing due to the module
+ request procedure. However, the open failure was
+ not being handled correctly.
+ Change: Fixed the device open error handling
+ Impact: 5771X/578XX
+
+
+uIP v0.7.4.1d (Mar 02, 2012)
+=======================================================
+ Fixes
+ -----
+ 1. Problem: Cont00061708 - Unable to log into target after running
+ driver load/unload
+ Cause: A bug was introduced in the previous bug fix (CQ61459)
+ where a pthread_cond_broadcast call was erroneously
+ enabled
+ Change: Restored this back
+ Impact: All
+
+
+uIP v0.7.4.1c (Feb 16, 2012)
+=======================================================
+ Fixes
+ -----
+ 1. Problem: Cont00061529 - Unable to connect to target after an
+ initial failed login attempt until iscsi service is
+ restarted
+ Cause: Upon a failed DHCPv4 acquisition due to the wrong VLAN
+ tag in the initial iface setup, any iscsid connect request
+ from the same NIC will get dropped due to a bug.
+ Change: Fixed the bug which prevented new iscsid connect requests
+ from getting honored
+ Impact: All
+
+ Enhancements
+ ------------
+ 1. Updated README
+
+
+uIP v0.7.4.1b (Feb 08, 2012)
+=======================================================
+ Fixes
+ -----
+ 1. Problem: Cont00061513 - Unable to connect to target over VLAN
+ interface
+ Cause: The VLAN id was not properly passed back to the CNIC
+ driver for the offload request
+ Change: Fixed the VLAN id being passed back to the CNIC driver
+ Impact: All
+
+
+uIP v0.7.4.1a (Feb 01, 2012)
+=======================================================
+ Fixes
+ -----
+ 1. Problem: Cont00049383 - No mechanism in iface file to support
+ gateway/routing
+ Change: Added support for the additional network parameters
+ as passed from the newer iscsi-util.
+ These parameters include:
+ IPv4: subnet_mask, gateway
+ IPv6: ipv6_linklocal, ipv6_router,
+ ipv6_autocfg, linklocal_autocfg, router_autocfg
+ VLAN: vlan_id, vlan_priority, vlan_state
+ Other: mtu, port
+ Impact: All
+
+ 2. Problem: Cont00060806 - Unable to connect target using DHCP over
+ tagged VLAN
+ Change: DHCP+VLAN is a new feature enhancement that was added
+ alongside all other new iface parameters.
+ Impact: All
+
+
+ Enhancements
+ ------------
+ 1. Lock iscsid's connect request with path_req so connect requests
+ with DHCP/Static will no longer override each other
+
+ 2. Fixed the if_down handler from global to nic specific
+
+ 3. Fixed various synchronization issues
+
+
+uIP v0.7.2.1e (Jan 05, 2012)
+=======================================================
+ Fixes
+ -----
+ 1. Problem: Cont00060734 - ifupdown-mtu change stress with active
+ session causes iscsiuio to fail
+ Change: Fixed a race condition between the nic enable thread
+ and when DHCP fails
+ Impact: All
+
+
+uIP v0.7.2.1d (Dec 28, 2011)
+=======================================================
+ Fixes
+ -----
+ 1. Problem: Cont00060368 - segfault observed after failing both
+ mpio paths
+ Change: Various memory leaks were identified and resolved in
+ the nic cleanup path
+ Impact: All
+
+
+uIP v0.7.2.1c (Dec 16, 2011)
+=======================================================
+ Enhancements
+ ------------
+ 1. Change: Disable HP SD mode
+
+
+uIP v0.7.2.1b (Dec 14, 2011)
+=======================================================
+ Enhancements
+ ------------
+ 1. Change: Default iscsiuio logging to off. Use the '-d'
+ option to enable
+
+
+uIP v0.7.0.14g (Oct 25, 2011)
+=======================================================
+ Enhancements
+ ------------
+ 1. Change: Fixed the compilation under RHEL6.2
+ 2. Change: Added oom_adjust call to prevent OOM Killer from killing
+ iscsiuio when memory is low
+ 3. Change: Added mlockall setting to prevent page swap
+
+
+uIP v0.7.0.14f (Oct 20, 2011)
+=======================================================
+ Fixes
+ -----
+ 1. Problem: Cont00058994 - DOS vulnerability in uip during UDP flood
+ Cause: The warning messages from the UDP handler was logging
+ at a rate faster than the log file logrotate rate
+ Therefore, the system's OOM eventually got kicked in to
+ start terminating running processes which includes iscsiuio
+ Change: Moved several UDP warning messages from the default log
+ level to the debug log level
+ Impact: All (minor)
+
+ 2. Problem: Cont00059288 - Show segfault w/ SLES11 SP1 Xen kernel
+ Cause: The bnx2x chip_id was not read correctly from the PCIe BAR1
+ under the Xen kernel. The error was in the mmap area.
+ Change: Corrected the mmapping of the PCI MMIO space.
+ Impact: Xen kernels
+
+ Enhancements
+ ------------
+ 1. Change: Changed the log file open error to a warning and let
+ the daemon progress. This was only observed under iSCSI boot
+
+
+uIP v0.7.0.14e (Sep 19, 2011)
+=======================================================
+ Fixes
+ -----
+ 1. Problem: Cont00058678 - Can not iboot target from ipv6 path
+ using VLAN
+ Cause: A bug was found in the path request path where the vlan
+ iface's protocol family was not used correctly in the
+ iface search
+ Change: This has been corrected
+
+
+uIP v0.7.0.14d (Sep 16, 2011)
+=======================================================
+ Fixes
+ -----
+ 1. Problem: Cont00058602 - Can't iboot using IPv6 offload path
+ Cause: The bug was exposed by a fix in 0.7.0.14c where the
+ IPv6 router solicitation timeout exceeded the nic
+ enable thread timeout.
+ Change: The IPv6 router solicitation timeout has been adjusted
+
+
+uIP v0.7.0.14c (Sep 01, 2011)
+=======================================================
+ Fixes
+ -----
+ 1. Problem: Cont00058256 - Sessions fail after loginstress to via
+ simultaneous ipv4 and ipv6 dhcp
+ Cause: Switching between DHCPv4/v6 coupled with VLAN exposed
+ a drawback in our nic_iface architecture design where
+ VLAN is not specified by iscsid.
+ Change: The code was optimized and improved the performance when
+ switching between DHCPv4/v6+VLAN. However, the ultimate
+ fix is to make use of the net config parameters introduced
+ in the newer open-iscsi util which will identify the
+ specific VLAN nic_iface to use.
+
+ Enhancements
+ ------------
+ 1. Change: Added support for bnx2x-1.71.00
+
+
+uIP v0.7.0.14b (Aug 23, 2011)
+=======================================================
+ Fixes
+ -----
+ 1. Problem: Cont00057840 - RHEL6.2 inbox: Unable to connect to
+ targets with 5709
+ Cause: For cases when the bnx2/bnx2x driver gets removed, the
+ uio database that was built by cnic would have the device
+ ->net reference removed. This has caused an unnecessary
+ timeout of 5s for each stale uio entry in the database.
+ Change: Adjusted the routine which seeks the device->net entry
+ to include more logic instead of hard waiting for 5s.
+
+ Enhancements
+ ------------
+ 1. Change: Added support for RHEL6.2 for out-of-box release
+ 2. Change: Updated the man page with -h and -p info
+ 3. Change: Updated the -h info
+
+
+uIP v0.7.0.13 (Aug 10, 2011)
+=======================================================
+ Fixes
+ -----
+ 1. Problem: Cont00057768 - iscsiuio logrotate causes daemon failure
+ Cause: The logrotate script will send a SIGUSR1 signal to notify
+ the iscsiuio daemon of such action. However, the daemon
+ wasn't programmed to catch this signal.
+ Change: Restored the catching of this signal
+
+
+uIP v0.7.0.12 (Aug 04, 2011)
+=======================================================
+ Fixes
+ -----
+ 1. Problem: Cont00050634 - brcm_iscsiuio Tainted: running IoZone,
+ Iometer and receiving a UDP flood on 3260
+ Cause: Upon iscsiuio termination, because of the UDP flood,
+ the nic thread will be busy servicing those UDP packets
+ while the signal handling thread will free up all nic
+ resources. The two threads were not in sync.
+ Change: Added a nic_remove_all routine to destroy all nic threads
+ before the nic resources get freed.
+
+ Enhancements
+ ------------
+ 1. Change: Fixed all warnings as reported by RHELS' Coverity testing.
+
+
+uIP v0.7.0.11 (Aug 02, 2011)
+=======================================================
+ Fixes
+ -----
+ 1. Problem: Erroneous VLAN tag was being passed by iscsid for connect
+ request
+ Cause: The iscsid's iface_rec_t ipc message does not contain this
+ vlan field. This field was added in uIP for future vlan
+ support. Since the buffer allocated to receive such message
+ in uIP didn't get initialized, therefore, garbled up VLAN
+ tag was getting used.
+ Change: Added the initialization of this buffer.
+
+
+uIP v0.7.0.10 (Jul 26, 2011)
+=======================================================
+ Fixes
+ -----
+ 1. Problem: Can't offload when switching from Static to DHCP then back to
+ Static IPv4 when connecting through a VLAN interface
+ Cause: The VLAN processing code did not reinstall the IP address
+ from the default nic_iface to the associated VLAN nic_iface.
+ This was only done on the very first time when the VLAN
+ interface was created and not on subsequent instances.
+ Change: Added code to mirror the default nic_iface IP/netmask/ip_config
+ on the VLAN nic_iface on every new connection request.
+
+
+uIP v0.7.0.9 (Jul 19, 2011)
+=======================================================
+ Fixes
+ -----
+ 1. Problem: Can't offload to 57810 NPAR NIC
+ Cause: The MF/VF variant of the PCI IDs were not supported previously
+ Change: Added support for the MF/VF variants for 57800/57810/57840
+
+
+uIP v0.7.0.8 (Jun 30, 2011)
+=======================================================
+ Fixes
+ -----
+ 1. Problem: Cont00056522 - Unable to connect to iSCSI target using
+ netxtreme2 package 7.0.9
+ Cause: The iSCSI L2 ring's CID has changed from 17 to 49
+ Change: The code now gets L2 iSCSI ring CID from the l2_buf directly.
+ This will work with any version of the cnic driver because
+ the location is a zero before this change.
+
+
+uIP v0.7.0.7 (Jun 23, 2011)
+=======================================================
+ Fixes
+ -----
+ 1. Problem: Cont00056460 - iSCSI Offload boot RHEL5u5 x64 dropped tagged
+ packets with iSCSI Offload Boot with untagged
+ Cause: The ICMP echo replies to the target was corrupted in both
+ 1g and 10g mode
+ Change: The code will now handle both VLAN stripped and no VLAN stripped
+ incoming packets correctly. Also modified the transmit routine
+ to strip out any inline VLAN tag before setting up the hw to
+ insert VLAN tag.
+
+
+uIP v0.7.0.6 (Jun 21, 2011)
+=======================================================
+ Fixes
+ -----
+ 1. Problem: Cont00056231 - DHCPv4 not working with iSCSI HBA w/
+ linux-nx2 v7.0.7
+ Cause: The 10g L2 FW HSI has been modified for PCIe performance
+ enhancement in the 7.0.7 package (FW 1.70.20) which uIP
+ has not adapted to.
+ Change: The eth_rx_cqe size has been increased from 32B to 64B.
+
+ Enhancements
+ ------------
+ 1. Change: The utility name has changed from brcm_iscsiuio to iscsiuio
+ as preparation for upstream submission.
+ 2. Change: Updated README
+
+
+uIP v0.7.0.5 (Jun 02, 2011)
+=======================================================
+ Fixes
+ -----
+ 1. Problem: Cont00055915 - iSCSI does not connect on 57800 in 4-port mode
+ Cause: The 4-port mode was not being determined correctly
+ Change: Fixed the PORT4MODE register offset and the QZONE_ID macros
+
+
+uIP v0.7.0.4 (May 24, 2011)
+=======================================================
+ Fixes
+ -----
+ 1. Problem: Cont00055832 - linux iscsiboot can not login to target using
+ offload path (57800)
+ Cause: The device ID comparison routine did not take care of the case
+ when one device ID is bitwise superset of another.
+ Change: Fixed the device ID comparison routine.
+
+
+uIP v0.7.0.3 (May. 19, 2011)
+=======================================================
+ Enhancements
+ ------------
+ 1. Change: Updated all fixes to match the released uIP 0.6.4.17
+
+ 2. Change: Modified source and Copyright info as preparation for upstream
+ submission
+
+
+uIP v0.7.0.2 (May. 03, 2011)
+=======================================================
+ Fixes
+ -----
+ 1. Problem: Cont00048972 - brcm-iscsi.log has no max size and would grow
+ to consume all free space on hard disk
+ Cause: There was no mechanism to rotate the log
+ Change: Added logrotate entry and SIGUSR1 signal handling for log rotate
+ action
+
+ 2. Problem: Cont00054996 - Multi-session, multi-protocol mtu stress
+ does not recover all sessions
+ Cause: A segfault was observed during the load/unload module. The
+ problem was caused by an illegal dereference of a pointer
+ when IPv6 couldn't find the longest match address from
+ the ARP (Neighbor) table.
+ Change: Fixed the dereferencing error
+
+ 3. Problem: Cont00054900 - Linux uIP - Please add ability to connect
+ to routed target with static iface IPv6
+ Cause: Static IPv6 never runs the IPv6 NDP router sol/adv engine.
+ Change: IPv6 NDP router sol/adv has now been added to static IPv6
+ operation.
+
+ 4. Problem: Cont00054996 - Multi-session, multi-protocol mtu stress
+ does not recover all sessions
+ Cause: Segfaults were observed caused by the accessing of the IPv6
+ NDP structure while the nic is undergoing a reset either
+ due to a DHCPv4 request from iscsid or the handling of
+ if_down due to the NL handler from CNIC.
+ Change: The fix involves the following:
+ - Fixed the handling of staggered IPv4/v6 DHCP/static requests
+ - Fixed memory leak due to reallocation of IPv4 and IPv6
+ DHCP structs
+ - Fixed the pthread join stuck problem in the handling
+ of the if_down NL message
+
+ 5. Problem: Cont00054810 - Linux NMI - bnx2x_init_hw_common:PXP2 CFG
+ failed running iSCSI MTU stress test
+ Cause: This only happens in DHCPv4 mode. The problem was caused
+ by contention between the elongated window of performing
+ DHCP in the enable_nic thread while receiving the asynchronous
+ if_down NL message (from the MTU change event) from the
+ CNIC NL thread. The problem occurs when the enable_nic
+ thread tries to call bnx2x_open while the other thread
+ calls the bnx2x_close routine.
+ Change: Fixed mutex lock bugs for the enable_nic thread. Also
+ extended the nic_disable timeout to 10s to compensate for
+ the DHCP operation.
+
+ 6. Problem: Cont00054818 - RH6.0 - Unable to logout of iSCSI session
+ after running PQA baseline scripts
+ Cause: This was caused by the call to cancel the enable_nic
+ thread when disabling the nic but failed to unlock the
+ nic mutex that the enable_nic thread held.
+ Change: Wake up the enable_nic thread and wait for it to complete
+ instead of canceling it in the nic_disable path.
+
+ 7. Problem: Cont00054725 - Previous static HBA IP will be used after
+ a new static HBA IP has been created
+ Cause: There was an assumption in the code where if the same
+ nic_iface structure was found based on the nic/vlan pair,
+ the specified IP address would not be used. Instead, it
+ will continue to use the previous defined IP address.
+ Change: The previous IP address will now be compared against the
+ the specified IP address before finishing the parce
+ iface request from iscsid. If different, the current
+ nic will be disabled and then re-enabled with the newly
+ specified IP address.
+
+ 8. Problem: Cont00054571 - Unable to connect to routed ipv6 target
+ with RA address and iface DHCPv6
+ Cause: The default router address was not being employed for
+ the IPv6 neighbor negotiation. Additionally, the return
+ address of our neighbor advertisement was incorrect as
+ it should use the best matched src address instead.
+ Change: Fixed both the IPv6 neighbor solicitation and advertisement
+ transmission and handling.
+
+ 9. Problem: Cont00054510 - fails to login to 32 session with blanket
+ login IPv6
+ Cause: A bug was introduced in uIP 0.6.4.6 where the NIC_RUNNING
+ flag might not be set when entering the main loop under
+ certain situations depending on the nic bring up.
+ Change: A new NIC_STARTED_RUNNING flag is now defined to fix CQ53511.
+
+ 10. Problem: Cont00053807 - RA and link local are unable to connect if DHCPv6
+ fails
+ Cause: The host link local address was not being searched as one of
+ the host address to be replied to CNIC for the connect request.
+ Change: The path reply now includes the search of host link local
+ address as well.
+
+ 11. Problem: Cont00054236 - iSCSI service must be restarted before an IPv6
+ connection can be made to the Equalogic target
+ Cause: The problem was intermittent as it depends on which IPv6 address
+ the target was redirecting to. Since uIP was only extracting
+ the target's IPv6 address + MAC from the target's neighbor
+ advertisement packet itself and not from the ICMPv6 option, so
+ the wrong or no MAC address will get send down to CNIC for the
+ connection establishment; hence the no connect.
+ Change: Added the updating of the neighbor discovery table to also use
+ the Target IPv6 address + MAC specified in the incoming neighbor
+ advertisement's ICMPv6 option field.
+
+ 12. Problem: Cont00053255 - bnx2x panic dump logging into multiple
+ discovered IPv6 nodes (Equalogic IPv6 target)
+ Cause: The bnx2x panic was fixed in the 10g fw 6.4.29.
+ A IPv6 connectivity issue was then found and led to different
+ kernel/uIP crashes. This was caused by the same IPv6
+ connectivity problem mentioned above.
+ Change: Same as above
+
+ 13. Problem: Cont00053728 - Sessions never recover after doing initiator-side
+ cable pull test with IPv6 traffic against Equalogic targets
+ Cause: It was discovered that the Equalogic would send out periodic
+ neighbor solicitation to maintain the connection to the
+ initiator. Since uIP was responding with the assigned IPv6
+ link local address in the neighbor advertisement
+ unconditionally, the target was observed to stop transmitting on
+ the connection specified.
+ Change: The neighbor advertisement generated will now use the dst IPv6
+ address from the input neighbor solicitation packet instead of
+ the assigned IPv6 link local address for both the packet and the
+ ICMPv6 source IPv6 address.
+
+ 14. Problem: Compile error under 32-bit OS
+ Cause: A bug was introduced in the previous release 0.6.4.6 which
+ caused a compilation error in 32-bit OS (64-bit compiles
+ fine)
+ Change: Fixed the bug
+
+ 15. Problem: Cont00053807 - RA and Link local are unable to connect if dhcpv6
+ fails
+ Cause: There was a bug in the nl reply where the RA address will never
+ be sent back to CNIC for the connection request
+ Change: The best matched address to the dst will now be sent back to
+ CNIC in the path rsp.
+
+ Enhancements
+ ------------
+ 1. Change: Updated README to remove the 57713/E references
+
+ 2. Change: Allow the ICMP option field in the IPv6 Neighbor Advertisement
+ response to be included without discrimination. This fixes
+ an issue connecting against the EQL via RA for DHCPv6.
+
+ 3. Change: Updated README for the IPv6 operation, VLAN, and discovery.
+
+
+uIP v0.7.0.1 (Mar. 29, 2011)
+=======================================================
+ Fixes
+ -----
+ 1. Problem: Cont00053511 - bnx2x panic dump during ifup/down stress with
+ iSCSI traffic
+ Cause: The panic dump was resolved by the driver's rq dbell size fix.
+ After that, uIP crashed due to the asynchronous if_down event
+ that took the chip resources away while the nic thread is still
+ continuing to try to send DHCP request.
+ Change: Added synchronization between the two threads so proper clean up
+ of the threads can occur.
+
+ Enhancements
+ ------------
+ 1. Change: Added support for E3 (57800, 57810, and 57840)
+
+
+uIP v0.6.4.5 (Mar. 23, 2011)
+=======================================================
+ Enhancements
+ ------------
+ 1. Change: Optimized the double VLAN fix of CQ53870 to match
+ what will be submitted for RHELS5.7 and RHELS6.1 inbox
+
+
+uIP v0.6.4.4 (Mar. 17, 2011)
+=======================================================
+ Fixes
+ -----
+ 1. Problem: Cont00053870 - Unable to login to iSCSI target via offload
+ through a Nexus 5020 switch with DCBx enabled
+ Cause: Double VLAN tagging was observed due to DCBx enabled.
+ The chip actually adds a VLAN tag if the txbd does not have
+ VLAN tag enabled under the DCBx environment for PRI setting.
+ Since uIP does not make use of hw assisted VLAN tagging,
+ 2 VLAN tag was observed in the data stream.
+ Change: Enabled hw assisted VLAN tagging in uIP for both 1g and 10g.
+
+ 2. Problem: Cont00053792 - maxconnections intermittently fail and
+ recover using iface DHCPv4
+ Cause: The DHCPv4 engine erroneously keeps on requesting for a
+ new lease which tremendously hamper normal path_req
+ operation. The problem is that the lease time parameter
+ has overflowed when converted to ticks count.
+ Change: Expanded the lease timer ticks count parameter from 16 to
+ 32 bits.
+
+ 3. Problem: Cont00053807 - RA and link local are unable to connect if
+ DHCPv6 fails
+ Cause: The DHCPv6 engine does not have the failover to use RA
+ mechanism
+ Change: Expanded to use best match address instead regardless of
+ DHCPv6 success or not, or using static v6.
+
+ Enhancements
+ ------------
+ 1. Change: Cont00051823 - Added man page for brcm_iscsiuio
+
+
+uIP v0.6.4.3 (Mar. 15, 2011)
+=======================================================
+ Fixes
+ -----
+ 1. Problem: Cont00053719 - intermittent logging into targets that
+ are not in the same subnet as defined in the iface
+ Cause: The default route was used erroneously due to a miscompare
+ Change: Fixed this comparison so if the requested dst is not in
+ in the same subnet, uIP would not even ARP out.
+
+ 2. Problem: Cont00053580 - Unable to do iSCSI boot into Linux OS using
+ 57710 adapters
+ Cause: The E1 iro USTORM_RX_PROD_OFFSET doesn't match the t6.4 fw
+ Change: This is now fixed
+
+
+uIP v0.6.4.2 (Feb. 24, 2011)
+=======================================================
+ Fixes
+ -----
+ 1. Problem: Cont00050343 - HBA does not follow RFC2131 spec for IPv4
+ DHCP lease expiration
+ Cause: The dhcp engine did not have this feature implemented
+ Change: Added lease time tracking and renewal
+
+ 2. Problem: Cont00050801 - Unable to connect to target after switching
+ between DHCPv4 to static v4
+ Cause: The configuration flags got corrupted when switching between
+ dhcp and static or vice versa.
+ Change: Fixed the flag handling. Also needed to zero out the static
+ ip address in the host memory when switching to dhcp.
+ Otherwise, the static ip address will get used mistakenly.
+
+ Enhancements
+ ------------
+ 1. Change: Cont00051936 - Added IPv6 NDP and DHCPv6 support.
+
+
+uIP v0.6.4.1 (Jan. 27, 2011)
+=======================================================
+ Fixes
+ -----
+ 1. Problem: Cont00049766 - segfault seen while stopping iscsi service
+ Cause: The logger output routine was accessing the log resource
+ while another thread calls fini_logger to free the same
+ resources
+ Change: Added pthread mutex lock to the logger routine to exclude
+ the initializer, user, and finisher
+
+ Enhancements
+ ------------
+ 1. Change: Added new t6.4 HSI and 57713 support.
+
+
+uIP v0.6.2.13 (Jan. 04, 2011)
+=======================================================
+ Fixes
+ -----
+ 1. Problem: Cont00049665 - iscsiboot:linux failed to boot into iscsi
+ boot image in offload path after 5 iterations
+ Cause: The hw consumer index for the uIP ring got out of sync
+ with the producer index. This has led to the xmit mutex
+ lock be held forever so subsequent ARP requests will not
+ get transmitted to the wire
+ Change: Added this out of sync detection and rescue the xmit mutex
+ lock
+
+uIP v0.6.2.12 (Dec. 21, 2010)
+=======================================================
+ Fixes
+ -----
+ 1. Problem: Cont00051820 - Session fails to reconnect after gateway
+ fallback
+ Cause: Under the HSRP test scenario, it was found that an ARP
+ request from the SUT is required in order for the HSRP
+ router to begin sending packets downstream to the SUT.
+ The default ARP age was originally set to 20 minutes
+ before a new ARP request will get sent,
+ Change: Changed the ARP age default to Linux default at 5 minutes
+
+uIP v0.6.2.11 (Dec. 17, 2010)
+=======================================================
+ Fixes
+ -----
+ 1. Problem: For IPv4, the gateway route was not being utilized
+ when the subnet mask given or calculated does not
+ match. This resulted in many unwanted connection
+ attempts.
+ Cause: A bug was found in the default gateway calculation
+ logic which prevented the gateway address from being
+ used.
+ Change: Fixed the default gateway logic
+
+ 2. Problem: For IPv6, there are scenarios where it won't connect
+ Cause: The IPv6 subnet mask as extracted from the CIDR
+ format might contain garbage data. This garbage data
+ was then used as part of the subnet mask which would
+ prevent the correct address mask.
+ Change: Fixed the subnet mask
+
+uIP v0.6.2.10 (Dec. 15, 2010)
+=======================================================
+ Fixes
+ -----
+ 1. Problem: IPv6 does not connect for non-CIDR iface.ipaddress
+ specification
+ Cause: A bug where all ones was used as the IPv6 netmask
+ instead of all zeroes. This prevented all IPv6
+ path requests from being honored
+ Change: Fixed the subnet mask used
+
+uIP v0.6.2.9 (Dec. 14, 2010)
+=======================================================
+ Enhancements
+ ------------
+ 1. Change: Added IP address CIDR notation support for the
+ iface.ipaddress field in the iface file.
+ This will allow subnet mask to be defined and used.
+
+uIP v0.6.2.8 (Dec. 9, 2010)
+=======================================================
+ Fixes
+ -----
+ 1. Problem: ipv6 + ifup/down fails to reconnect
+
+ Cause: There were 2 problems found:
+ - the xmit_mutex lock was being held indefinitely
+ - the nl_process_if_down flag for 10g doorbell ringing
+ did not get reinitialized
+
+ Change: Fixed the xmit_mutex deadlock via trylock
+ Added nl_process_if_down initialization in the IF_DOWN
+ process
+
+ 2. Problem: Added fix for the NPAR disabled for 57712
+
+ Cause: The mac address was not handled correctly
+
+ Change: Fixed the mac address handling. Also requires corresponding
+ kernel component for the complete fix
+
+uIP v0.6.2.7 (Dec. 7, 2010)
+=======================================================
+ Enhancements
+ ------------
+ 1. Change: Use the gateway address from the DHCP server the
+ destination IP address is not in the current subnet.
+
+uIP v0.6.2.6 (Nov. 16, 2010)
+=======================================================
+ Fixes
+ -----
+ 1. Problem: Warning message seen in the kernel logs,
+ "uio uio2: uevent: unsupported action string"
+
+ Cause: The improper string was echo'ed into the UIO trigger
+ field. With an improper string, this message would
+ appear in the kernel logs.
+
+ Change: uIP will now write the string "online" to the UIO
+ trigger field. This is the string expected by the
+ Linux kernel base driver.
+
+ 2. Problem: uIP would segfault during a heavily login/logout
+ iSCSI subsystem reset senario
+
+ Cause: A double free occurred in the logging portion of the
+ uIP code, but this was root cause to a double free when
+ manipulating the NetLink buffers.
+
+ Change: Properly look at the return code from the routine which
+ will read NetLink messages. Also only free buffers
+ if they are allocated.
+
+ Enhancements
+ ------------
+ 1. Change: Add ability to print kernel version and machine
+ architecture to further help debug problems.
+
+ 2. Change: Apply the netmask from DHCP if provided.
+
+uIP v0.6.2.5 (Nov. 10, 2010)
+=======================================================
+ Fixes
+ -----
+ 1. Problem: iscsid would try to conenct with unintended iSCSI
+ targets
+
+ Cause: uIP would blindly return the iSCSI target MAC address
+ regardless if the iSCSI target is reachable via the
+ given port.
+
+ Change: uIP will try to filter the requests coming from CNIC
+ by automatically generating a network mask based off
+ the configured IP addressed. Then this netmask is
+ masked with the destination IP address. If there is
+ a match, then the path_req is allowed through.
+
+ 2. Problem: Problems reconnecting back to the target when running
+ MTU stress tests.
+
+ Cause: cnic/bnx2i and uIP could possibly get out of sync when
+ an if_down message is sent.
+
+ Change: uIP will now immediately react to the if_down message,
+ and flush all the path req's and then to process to
+ if_close.
+
+ Enhancements
+ ------------
+ 1. Change: Fix compile warnings for src/unix/nic_nl.c,
+ and src/unix/main.c
+
+uIP v0.6.2.4 (Nov. 4, 2010)
+=======================================================
+ Fixes
+ -----
+ 1. Problem: iSCSI HBA: brcm_iscsiuio segfault during ifdown
+ with many active sessions
+
+ Cause: uIP will segfault when traversing the error path when
+ an iSCSI connection is starting but the sysfs entries
+ have not been created yet.
+
+ Change: Use the errno value rather then the one from the file
+ descriptor because the file descriptor will be NULL and
+ the NULL dereference will cause a segfault.
+
+ Enhancements
+ ------------
+ 1. Change: Added initial changes for iSCSI multi-function support for
+ 10G NIC's.
+ 2. Change: Add more detailed messages for error pathes in nic_utils
+
+uIP v0.6.2.3 (October 28, 2010)
+=======================================================
+ Enhancements
+ ------------
+ 1. Change: Add support for bnx2x-1.62.x drivers
+
+uIP v0.6.2.2 (October 18, 2010)
+=======================================================
+ Enhancements
+ ------------
+ 1. Change: Only allow iSCSI connections with known bnx2x HSI's.
+
+uIP v0.6.2.1 (October 7, 2010)
+=======================================================
+ Fixes
+ -----
+ 1. Problem: After multiple MTU changes, the ethtool IOCTL used to
+ determine the bnx2x driver version fails and eventually
+ iSCSI connections would not reconnect.
+
+ Cause: The socket file descriptor used during the ethtool IOCTL
+ call was never closed and leaked.
+
+ Change: On the error path when calling the ethtool IOCTL, the
+ file descriptor is now properly closed.
+
+uIP v0.5.39 (September 15, 2010)
+=======================================================
+ Fixes
+ -----
+ 1. Problem: Could not offload IPv4 VLAN connection when the target tries
+ to ARP the iSCSI initiator
+
+ Cause: In the ARP reply, the ether field was incorrect.
+
+ Change: Properly set the ether field to 802.1Q type (0x8100)
+
+uIP v0.5.38 (September 14, 2010)
+=======================================================
+ Fixes
+ -----
+ 1. Problem: uIP would cause a panic dump when the NIC was going down
+
+ Cause: uIP and CNIC where not synchonized on NIC state
+
+ Change: Check if the RX BD's which are zero'ed by CNIC when the
+ NIC is going down. If the BD addresses are zero, then
+ uIP will drop the TX packets.
+
+uIP v0.5.37 (August 21, 2010)
+=======================================================
+ Fixes
+ -----
+ 1. Problem: uIP would segfault on ifup/ifdown stress test when using
+ DHCP to determine local IP address.
+
+ Cause: The uIP would use a NULL buffer during data transmission.
+
+ Change: Drop packets when there are no buffer avaliable.
+
+uIP v0.5.36 (August 21, 2010)
+=======================================================
+ Fixes
+ -----
+ 1. Problem: iSCSI boot would not completely login after the pivot
+ root operation.
+
+ Cause: The uIP would not properly start the NIC interface.
+
+ Change: uIP should only check the NIC state to determine whether
+ to start the NIC thread or not.
+
+ 2. Problem: uIP would segfault during if'up if'down testing.
+
+ Cause: The uIP would improperly start 2 NIC threads for the
+ same NIC interface.
+
+ Change: uIP should properly lock the NIC list when disabling/removing
+ the NIC threads.
+
+
+uIP v0.5.35 (August 20, 2010)
+=======================================================
+ Fixes
+ -----
+ 1. Problem: Sessions would hang with ethtool self-test
+
+ Cause: The uIP would hang because the socket layer was stuck
+ because there is much contention for that socket. This
+ would hang the CNIC thread.
+
+ Change: Remove any IOCTL calls in uIP which may colide with
+ the ethtool self test. The driver version is only
+ capture during uIP initialization.
+
+ 2. Problem: There were session recovery issue when using DHCP
+ if up/down tests.
+
+ Cause: The uIP would hang because the DHCP requests would
+ timeout if the network interface is downed which would
+ hang all the other uIP threads.
+
+ Change: Ensure that the DHCP state machine had exit points
+ if the network interface was down'ed.
+
+
+uIP v0.5.34 (August 18, 2010)
+=======================================================
+ Fixes
+ -----
+ 1. Problem: Sessions would not recover with ethtool self-test
+
+ Cause: The uIP would hang because either the NetLink buffer is
+ full or that any socket operations used to manipulate
+ multicast addresses would block.
+
+ Change: Ensure that the socket used for multicast addressing is
+ set to nonblocking. Drain the NetLink buffer without
+ using the eventing, but with a more aggressive poll routine.
+
+ 2. Problem: Sessions would not recover with L2 driver load/unload on
+ RHEL 6.0 SS9
+
+ Cause: The uIP would close the NIC thread too early and would
+ deadlock on cloing the NIC thread.
+
+ Change: Ensure that the NIC thread is canceled/closed only in one
+ location, in the NIC remove routine.
+
+
+uIP v0.5.33 (August 17, 2010)
+=======================================================
+ Fixes
+ -----
+ 1. Problem: Error message seen from the uIP stack for valid packets.
+
+ Cause: The uIP was incorrectly marking logging messages for valid
+ packets as errors because it didn't know how to parase them.
+
+ Change: Changed the following from error to debug message
+ ipv6: invalid version
+ ipv4: invalid version or header length.
+ icmpv6: unknown ICMP message.
+ ip: neither tcp nor icmp
+ Changed the following from error to warn message
+ udp: bad checksum
+ tcp: bad checksum
+ tcp: got reset, aborting connection.
+
+ 2. Problem: After multiple iterations the loading and unloading of
+ the Broadcom Linux drivers with active connections
+ would not cause the sessions to recover on RHEL 6.0
+ snapshot 9.
+
+ Cause: There was a deadlock in the nic mutex
+
+ Change: Lock ordering for the nic mutex and nic list mutex must
+ be inforced.
+
+ 3. Problem: After multiple iterations of running the ethtool selftest
+ the Broadcom Linux drivers with active connections
+ would not cause the sessions to recover on RHEL 5.5.
+
+ Cause: The Netlink buffer between uIP and CNIC would get full.
+
+ Change: Poll more regularly for packets in the Netlink buffer
+ from 4 times a second to 100 times a 1 second.
+ Drain packets during the PATH_REQ packet pull.
+
+
+uIP v0.5.32 (August 14, 2010)
+=======================================================
+ Fixes
+ -----
+ 1. Problem: Error message 'nic eth0: Didn't find type 0xaa bb' seen.
+
+ Cause: Valid non-DIX Ethernet packets as being passed to the
+ uIP. uIP will drop these packets but should be logged
+ correctly.
+
+ Change: These packets are valid, and should only be logged for
+ debugging purposes.
+
+ 2. Problem: Error message 'Dropped previous transmitted packet' seen.
+
+ Cause: The TX ring is full, and here uIP is trying to transmit a
+ packet which will be dropped. This is a valid state but
+ the log message is marked incorrectly
+
+ Change: These messages are not warnings and should be logging when
+ debugging is enabled.
+
+ 3. Problem: Error message: "iscsi_ipc eth0 Transport name is not
+ equal expected: got: bnx2i" seen.
+
+ Cause: The iface_rec structure is different between iscsid version.
+ For RHEL 5.5, iscsid is versioned 871, for RHEL 6.0 is
+ versioned 872.
+
+ Change: Allow uIP to compile against a different version of iscsid.
+
+
+uIP v0.5.31 (August 12, 2010)
+=======================================================
+ Fixes
+ -----
+ 1. Problem: Softlock would occur showing that the NetLink table
+ lock was taken but never released.
+
+ Cause: NetLink socket buffer would fill with constant PATH_REQ
+ messages preventing PATH_REQ response from libiscsi
+
+ Change: Now uIP will drain the NetLink buffer while looking for
+ a response.
+
+ Enhancements
+ ------------
+ 1. Change: Add documentation for VLAN configuration and restrictions.
+
+
+uIP v0.5.30 (August 6, 2010)
+=======================================================
+ Fixes
+ -----
+ 1. Problem: iscsid thread will stall if closing the uio files nodes
+ is stuck
+
+ Cause: uIP would indefinitely block waiting for the mutex shared
+ by the close routine.
+
+ Change: Now uIP will try and poll a bit for the mutex. If it can't
+ get this mutex in the iscsid thread then an error is return
+ rather then hold the thread.
+
+ 2. Problem: IPv6 Unicast Neighbor Adveriserments would have the
+ ICMPv6 option header specifying a MAC.
+
+ Cause: uIP should use the source IPv6 address to detmine whether
+ to strip the option header or not and not the target address
+ in the ICMPv6 field.
+
+ Change: The uIP stack return a unicast IPv6 Neighbor Advertisement
+ without the ICMPv6 option as a response to unicast
+ IPv6 Neighbor Solicitations.
+
+ 3. Problem: There would be TCP SYN packets with improper MAC address.
+
+ Cause: A zero'ed MAC address was not passed to CNIC to indicate an
+ error or if the IP address didn't resolve.
+
+ Change: The uIP stack will now return a zero'ed MAC address if it
+ can't find any entries.
+
+
+uIP v0.5.29 (August 6, 2010)
+=======================================================
+ Fixes
+ -----
+ 1. Problem: "uip udp: no matching connection found: lport: 35072"
+ seen numerous times in the brcm_iscsiuio log file
+
+ Cause: This message was incorrectly marked as an error
+
+ Change: These messages are valid log entries especially if the
+ packet was a broadcast UDP packet not destined for the SUT
+ I will change the code to mark these logs entries as debug.
+
+
+uIP v0.5.28 (August 5, 2010)
+=======================================================
+ Fixes
+ -----
+ 1. Problem: Can't login into a redirected Equilogic Target
+
+ Cause: The Equilogic Target uses a unicast IPv6 Neighbor
+ Solicitation to test if the host is up. The uIP stack
+ would return a Neighbor Advertisement with an unneeded
+ ICMPv6 option.
+
+ Change: Only have the uIP stack return a unicast IPv6 Neighbor
+ Advertisement without the ICMPv6 option.
+
+ 2. Problem: With older bnx2/bnx2x/cnic/bnx2i driver combinations
+ uIP would segfault when these drivers were unloaded.
+
+ Cause: When the older drivers were removed, the underlying uio
+ instance was removed causing uIP to have a stale file handle.
+ When uIP finally closes using this stale file handle, either
+ uIP would segfault, or there would be an error in the
+ uio_release() path.
+
+ Change: Only have the uIP close if the UIO file node exists.
+
+
+uIP v0.5.27 (July 31, 2010)
+=======================================================
+ Fixes
+ -----
+ 1. Problem: iSCSI HBA: Unable to use DHCP address for iSCSI interface
+ if a connection was previously made with a static address
+ on bnx2 devices.
+
+ Cause: Because the device is closed and reopen'ed the TX consumer
+ indexes were not persisted
+
+ Change: Only discard the TX consumer indexes only when the devices
+ will be discarded or closed
+
+ Enhancements
+ ------------
+ 1. Change: Change CNIC references to bnx2 in the bnx2 user space
+ driver.
+
+
+uIP v0.5.26 (July 30, 2010)
+=======================================================
+ Fixes
+ -----
+ 1. Problem: iSCSI HBA: Unable to use DHCP address for iSCSI interface
+ if a connection was previously made with a static address on
+ bnx2x devices.
+
+ Cause: Because the device is closed and reopen'ed the TX consumer
+ indexes were not persisted
+
+ Change: Only discard the TX consumer indexes only when the devices
+ will be discarded
+
+ 2. Problem: IPv6 using VLAN's didn't login
+
+ Cause: The uIP code used to determine if the packet was an IPv6
+ or not was not working. This VLAN packets for IPv6 were
+ being mis-interpreted.
+
+ Change: Make the function is_ipv6() VLAN aware
+
+ 3. Problem: Persistant targets was not loggin in during boot
+
+ Cause: If udev was slow and the /dev/uio* were creatly slowly
+ uIP would fail.
+
+ Change: Poll uIP waiting for /dev/uio* file nodes.
+
+uIP v0.5.25 (July 27, 2010)
+=======================================================
+ Fixes
+ -----
+ 1. Problem: When using IPv4 DHCP, there are no initial DHCP Discover
+ packets were not seen on the wire.
+
+ Cause: Packets generated from the app handler from the uIP stack
+ were not placed on the wire.
+
+ Change: Packets originating from the uIP stack are now always placed
+ on the wire.
+
+uIP v0.5.24 (July 25, 2010)
+=======================================================
+ Fixes
+ -----
+ 1. Problem: One would see invalid packet packets flow through the
+ uIP stack, where the logs would indicate there is a packet
+ with an invalid length
+
+ Cause: The BD and CQE consumer indexes were not properly incremented
+ and masked.
+
+ Change: The BD index is now properly masked. The CQE index is not
+ incremented using the CQE index rather the mistaken BD index.
+
+ Impact: 10G only
+
+ 2. Problem: uIP would segfault during the booting of the machine.
+
+ Cause: uIP was using a NULL data pointer because there was an
+ incorrect packet passed to the stack.
+
+ Change: Only allow uIP to process data if the packet exists.
+
+ 3. Problem: uIP would stop processing packets
+
+ Cause: The uIP code would not properly drain the CQE ring causing
+ it to eventually be full
+
+ Change: Consume all the CQE elements even if they are ethernet types
+ or not.
+
+ Impact: 10G only
+
+ 4. Problem: uIP would stop after if/down of the network interface.
+
+ Cause: uIP was not kick starting the NIC loop thread properly.
+
+ Change: Ensure that the NIC loop thread is started by when iscsid
+ request that the interface start the offload. Mark the NIC
+ only if the thread is truly canceled.
+
+
+uIP v0.5.23 (July 20, 2010)
+=======================================================
+ Fixes
+ -----
+ 1. Problem: Segfault during brcm_iscsiuio initialization
+
+ Cause: uIP was using a NULL data pointer, because a different
+ thread re-initialized the uIP stack
+
+ Change: Properly synchronize the initialization of the stack
+
+ 2. Problem: Deadlock during the printing of heavy debug messages
+
+ Cause: The variable macro structures would point to invalid
+ data
+
+ Change: With each invocation of va_copy() a corresponding
+ invocation of va_end() in the same function for the proper
+ cleanup
+
+ 3. Problem: uIP would hang when the interface could go up/down
+
+ Cause: uIP would get out of sync with the state of the network
+ interface
+
+ Change: Instead of detriving state from the UIO file nodes, uIP
+ will take direction from iscsid on when interfaces will be
+ started.
+
+uIP v0.5.22 (July 15, 2010)
+=======================================================
+ Fixes
+ -----
+ 1. Problem: Unable to reconnect via iSCSI offload after
+ ifup/ifdown
+
+ Cause: uIP was stuck on the thread when closing the NIC main
+ loop
+
+ Change: Properly synchronize the NetLink CNIC and uevent threads
+
+ 2. Problem: uIP would crash during boot up.
+
+ Cause: uIP would overwrite a memory location which was already
+ freed during nic_remove().
+
+ Change: Since the NIC is freed there is no need to write to
+ update the NIC flags
+
+ Enhancements
+ ------------
+
+ 1. Change: Added IPv6 Link Local support
+
+
+uIP v0.5.21 (July 5, 2010)
+=======================================================
+ Fixes
+ -----
+ 1. Problem: Unable to connect via iSCSI offload after
+ changing L2 address
+
+ Cause: uIP didn't notice the network inferface going down
+
+ Change: Allow uIP to persist the stack's IP address after
+ a reset
+
+ 2. Problem: Unable to connect via IPv4 and IPv6 concurrently
+
+ Cause: uIP didn't notice the network inferface going down
+
+ Change: Allow uIP to persist the stack's IP address after
+ a reset and properly bring up the interface
+
+ 3. Problem: Unable to connect via VLAN
+
+ Cause: IP address was no persisted after a device reset
+
+ Change: When CNIC requests a path request, uIP will use the
+ VLAN passed by the CNIC.
+
+
+uIP v0.5.20 (June 24, 2010)
+
+
+uIP v0.5.20 (June 24, 2010)
+=======================================================
+ Fixes
+ -----
+ 1. Problem: Certain IPv6 addresses are not repsonded to by
+ the target.
+
+ Cause: The MAC was generated from the target's IPv6
+ address not the deterived multicast IPv6 address.
+
+ Change: The destination MAC address should be deterived
+ from the packet's destination IPv6 address and
+ not the target.
+
+ 2. Problem: brcm_iscsiuio would segfault when L2 interface is
+ bought up and down after being logged into
+
+ Cause: The NIC thread was not stopped properly
+
+ Change: When the UIO device is remove and when the
+ cooresponding NIC tracked by brcm_iscsiuio, the
+ daemon would properly wait for the NIC thread to
+ stop.
+
+
+uIP v0.5.19 (June 22, 2010)
+=======================================================
+ Fixes
+ -----
+ 1. Problem: Can't login after boot
+
+ Cause: If NIC interfaces are brough up and down quickly
+ uIP wait on an invalid NIC thread
+
+ Change: Only wait for the NIC thread if the NIC thread
+ exists.
+
+uIP v0.5.18 (June 21, 2010)
+=======================================================
+ Fixes
+ -----
+ 1. Problem: Does not compile on SLES 11 SP1
+
+ Cause: Automake cached files were included as part of the
+ uIP-0.5.17 package
+
+ Change: Remove automake cached files, and allow these files
+ to be generated each time the source is compiled
+
+ 2. Problem: Does not always receive multicast packets
+
+ Cause: Multicast bit was not set in SORT USER 2 register
+
+ Change: brcm_iscsiuio will now set the SORT USER 2 registers
+ with both the broadcast and multicast bits.
+
+ 3. Problem: Existing iSCSI connections do not reconnect after
+ operations which require equivalent driver
+ load/unload operations
+
+ Cause: Multiple path requests would trample NIC configurations
+
+ Change: Allow only one path request at a time
+
+uIP v0.5.17 (June 16, 2010)
+=======================================================
+ Fixes
+ -----
+ 1. Problem: IPv6 neighbor solicitations from brcm_iscsiuio could
+ not be responded to
+
+ Cause: The IPv6 neighbor solicitation packet had an invalid
+ multicast MAC address
+
+ Change: Properly set the MAC address multicast bit and OR
+ with the IPv6 destination address
+
+ 2. Problem: NIC state was not properly synchronized and noticed
+ by Shyam Iyer <shiyer@redhat.com>
+
+ Change: Properly lock the NIC device when changing state
+
+ Enhancements
+ ------------
+
+ 1. Change: Listen for iscsid before daemonizing to close a timing
+ gap which might allow iscsid to start before uIP is
+ completely initialized.
+
+uIP v0.5.16 (June 2, 2010)
+=======================================================
+
+ Enhancements
+ ------------
+
+ 1. Change: Formally add IPv6 support. Only a static IPv6 address
+ is supported.
+
+uIP v0.5.15 (May 20, 2010)
+=======================================================
+
+ Fixes
+ -----
+ 1. Problem: brcm_iscsiuio would echo packets off the wire
+
+ Cause: Stale packets from the uIP stack could potentially
+ make it onto the wire causing a network flood
+
+ Change: Only place on the wire packets uIP intended to place
+ on the wire. Drop all other packets.
+
+uIP v0.5.14 (May 18, 2010)
+=======================================================
+
+ Fixes
+ -----
+ 1. Problem: brcm_iscsiuio would crash when offloading using a
+ bnx2x device /dev/mem could not be
+ opened, (ie. SE Linux enabled)
+
+ Cause: /dev/mem could not be opened, (ie. SE Linux enabled)
+ and then the NIC would be improperly initialized.
+
+ Change: If /dev/mem is not able to be opened, then the device
+ is closed
+
+ 2. Problem: brcm_iscsiuio would crash when brcm_iscsiuio is
+ being shutdown
+
+ Cause: The NIC mutex was deferenced imporperly when the NIC
+ is being closed
+
+ Change: Take the NIC mutex lock only when the NIC is closed.
+
+uIP v0.5.13 (May 16, 2010)
+=======================================================
+
+ Fixes
+ -----
+ 1. Problem: brcm_iscsiuio would crash with heavy traffic directed
+ at the iSCSI traffic
+
+ Cause: Packets which are sized between 1006-1024 bytes would
+ crash brcm_iscsiuio because brcm_iscsiuio is not sized
+ to handle such large packets
+
+ Change: Drop large packets, properly hold the NIC mutex lock
+ for the duration when NIC fields are being used.
+
+
+uIP v0.5.12 (May 13, 2010)
+=======================================================
+
+ Fixes
+ -----
+ 1. Problem: brcm_iscsiuio could crash on when L2 interface is
+ ifdown'ed
+
+ Cause: The local NIC pointer was not initialized properly
+ in the routine parse_iface()
+
+ Change: Properly initialize the NIC pointer
+
+ 2. Problem: Documentation referred to older admin_client which
+ doesn't exist any more because brcm_iscsiuio uses
+ the iscsid iface file
+
+ Change: Remove the stale references
+
+
+uIP v0.5.11 (May 11, 2010)
+=======================================================
+
+ Fixes
+ -----
+ 1. Problem: brcm_iscsiuio could crash on invalid packet sizes
+
+ Cause: The hardware BD could be a large value because of a
+ hardware error
+
+ Change: Limit the size of the packet dumped to the MTU size
+
+ Enhancements
+ ------------
+
+ 1. Change: During the running of the configure script now
+ the script will check for ar and ranlib binaries
+
+
+uIP v0.5.10 (May 03, 2010)
+=======================================================
+
+ Fixes
+ -----
+ 1. Problem: BCM57712 not recognized
+
+ Cause: The PCI ID's in the bnx2x file were missing.
+
+ Change: Added proper BCM57712, BCM57712E, BCM57713, BCM57713E
+ PCI ID's
+
+ 2. Problem: (CQ 47481) brcm_iscsiuio not installed in correct location
+
+ Cause: Default install path for autoconf is /usr/local
+
+ Change: Change the default prefix to '/' so the brcm_iscsiuio
+ binary is installed to /sbin/
+
+ Enhancements
+ ------------
+
+ 1. Change: Remove dependency on Yacc and Lex
+
+
+uIP v0.5.9 (April 28, 2010)
+=======================================================
+
+ Fixes
+ -----
+ 1. Problem: bnx2x T6.0 driver would not login
+
+ Cause: The bnx2x code was not using the T6.0 HSI offsets
+
+ Change: Determine to bnx2x driver version eariler to properly use the
+ T4.8 or T6.0 HSI
+
+ Enhancements
+ ------------
+
+ 1. Change: Collapse all the various locks to use the NIC lock to shrink
+ memory footprint
+
+ 2. Change: Consolidate upper layer checksumming code
+
+
+uIP v0.5.5 (March 02, 2010)

+ iface before logging in
+
+uIP v0.5.6 (Mar 05, 2009)
+=======================================================
+ Fixes
+ -----
+ 1. Problem: bnx2x panic dump would be seen when sending
+ traffic to uIP
+
+ Cause: The TX producer index was not properly
+ incrementing when the wrapping occured
+
+ Change: Do not skip the last TX producer index like the
+ TX BD's
+
+ Impact: None.

+ NIC thread is destroyed when the host network
+ interface is brought down.
+
+ Impact: None.
+
+
+uIP v0.5.1 (Dec 9, 2009)
+=======================================================
+ Fixes
+ -----
+ 1. Problem: 10G devices behind PCI bridges would not collect

+* A new API: protosockets that are similar to BSD sockets but does not
+ require any underlying multithreading system.
+
+* Very rudimentary IPv6 support
+
+* New application: DHCP client. Web server rewritten with protosockets.
+
+* Removed uIP zero-copy functionality in order to simplify uIP device
+ driver coding: outbound packets are now *always* stored in full in
+ the uip_buf buffer.
+
+* Checksum computation is now part of uip.c, but it still is possible
+ to implement them in assembly code by specifying a configuration
+ option. Checksum code now runs on architectures with 2-byte alignment.
+
+* Added TCP persistent timer.
+
+* Made all IP address representations use the new uip_ipaddr_ip
+ datatype for clarity.
+
+* Updated window behavior so that sending to a host with a small open
+ window works better now.
+
+* UDP API change: uip_udp_new() now takes port numbers in network byte
+ order like TCP functions.
+
+* Allow reception of packets when no IP address is configured to make
+ DHCP work.
+
+* Moved Ethernet address into main uIP module from ARP module.
+
+* Made constants explicit #defines and moved them out of the code
+ (header sizes, TCP options, TCP header length field).
+
+* If uip_len is less than that reported by the IP header, the packet
+ is discarded. If uip_len is greater than the length reported by the
+ IP header, uip_len is adjusted.
+
+* Moved header size definitions into header file.
+
+* Added uIP call for polling an application without triggering any
+ timer events. Removed redundant assignments of uip_len and uip_slen.
+
+* Removed compiler warning about icmp_input label being defined when
+ UIP_PINGADDRCONF was not used.
+
+* Added UIP_APPDATA_SIZE macro that holds the available buffer size
+ for user data.
+
+* Added uip_udp_bind() call.
+
+* Moved checksum code into main uIP module.
+
+* Switched the TCP, UDP and IP header structures to be structs rather
+ than typedefs.
+
+* Prefixed TCP state names with UIP_ to avoid name space
+ contamination.
+
+* Changed declarations of uip_appdatap and friends to void * to avoid
+ explicit typecasts.
+
+* Bugfixes
+
+ o TCP: Fixed bug with high byte of peer window size.
+
+ o TCP: Fixed bug that in some cases prevented concurrent reception and
+ transmission of TCP data.
+
+ o TCP: uip_connect() didn't correctly calculate age of TIME_WAIT
+ connections.
+
+ o TCP: Array index for uip_conns[] array was out of bounds in
+ comparison. Comparison changed to make index within bounds.
+
+ o TCP: if the remote host crashes and tries to reestablish an old
+ connection, uIP should respond with an ACK with the correct
+ sequence and acknowledgment numbers, to which the remote host
+ should respond with an ACK. uIP did not respond with the correct
+ ACK.
+
+ o TCP: Fixed check for SYNACK segment: now checks only relevant TCP
+ control flags and discards flags reserved for future expansion.
+
+ o TCP: Fixed bug where uIP did not inform application that a connection
+ had been aborted during an active open.
+
+ o TCP: FIN segment was accepted even though application had stopped
+ incoming data with uip_stop().
+
+ o TCP: A FINACK segment would not always correctly acknowledge data.
+
+ o UDP: checksums are now calculated after all fields have been
+ filled in.
+
+ o UDP: network byte order on lastport in uip_udp_new().
+
+ o IP: memset() bugs in IP fragment reassembly code fixed.

+/**
+ * \defgroup psock Protosockets library
+ * @{
+ *
+ * The protosocket library provides an interface to the uIP stack that is
+ * similar to the traditional BSD socket interface. Unlike programs
+ * written for the ordinary uIP event-driven interface, programs
+ * written with the protosocket library are executed in a sequential
+ * fashion and does not have to be implemented as explicit state
+ * machines.
+ *
+ * Protosockets only work with TCP connections.
+ *
+ * The protosocket library uses \ref pt protothreads to provide
+ * sequential control flow. This makes the protosockets lightweight in
+ * terms of memory, but also means that protosockets inherits the
+ * functional limitations of protothreads. Each protosocket lives only
+ * within a single function. Automatic variables (stack variables) are
+ * not retained across a protosocket library function call.
+ *
+ * \note Because the protosocket library uses protothreads, local
+ * variables will not always be saved across a call to a protosocket
+ * library function. It is therefore advised that local variables are
+ * used with extreme care.
+ *
+ * The protosocket library provides functions for sending data without
+ * having to deal with retransmissions and acknowledgements, as well
+ * as functions for reading data without having to deal with data
+ * being split across more than one TCP segment.
+ *
+ * Because each protosocket runs as a protothread, the protosocket has to be
+ * started with a call to PSOCK_BEGIN() at the start of the function
+ * in which the protosocket is used. Similarly, the protosocket protothread can
+ * be terminated by a call to PSOCK_EXIT().

+/*
+ * uIP is a small implementation of the IP, UDP and TCP protocols (as
+ * well as some basic ICMP stuff). The implementation couples the IP,
+ * UDP, TCP and the application layers very tightly. To keep the size
+ * of the compiled code down, this code frequently uses the goto
+ * statement. While it would be possible to break the uip_process()
+ * function into many smaller functions, this would increase the code
+ * size because of the overhead of parameter passing and the fact that
+ * the optimier would not be as efficient.
+ *
+ * The principle is that we have a small buffer, called the uip_buf,
+ * in which the device driver puts an incoming packet. The TCP/IP
+ * stack parses the headers in the packet, and calls the
+ * application. If the remote host has sent data to the application,
+ * this data is present in the uip_buf and the application read the
+ * data from there. It is up to the application to put this data into
+ * a byte stream if needed. The application will not be fed with data
+ * that is out of sequence.
+ *
+ * If the application whishes to send data to the peer, it should put
+ * its data into the uip_buf. The uip_appdata pointer points to the
+ * first available byte. The TCP/IP stack will calculate the
+ * checksums, and fill in the necessary header fields and finally send
+ * the packet back to the peer.

+#
+# iscsi_offload
+#
+# Configure iSCSI offload engines for use with open-iscsi
+# Usage:
+# iscsi_offload [-d | -f | -i <ipaddr> | -t ] <nic>
+#
+# Copyright (c) 2011 Hannes Reinecke, SUSE Labs
+# This script is licensed under the GPL.
+#
+# The script creates an open-iscsi interface definition
+# in the style <nic>-<module>, where <nic> matches the
+# network interface passed on the commandline.
+# If '-t' (test mode) is passed as an option, the script
+# will not create nor modify any setting but just print
+# the currently active ones.
+#
+# Currently the script works with Broadcom (bnx2i) and
+# Chelsio T3 (cxgbi) iSCSI offload engines.
+# Should work with Chelsio T4, but has not been tested.
+# ServerEngines (be2iscsi) and QLogic (qla4xxx) can only
+# be configured via BIOS, open-iscsi support is still in
+# development.
+#
+
+#
+# Return codes:
+# 0: Success
+# 1: Invalid command line parameter
+# 2: iSCSI offloading not supported
+# 3: Error during module loading
+# 4: Cannot configure interface via iscsiadm, use BIOS setup
+# 5: internal error running iscsiadm
+#
+# Output:
+# <mac> [none|dhcp|ip <ipaddr>|ibft]
+# where
+# <mac>: MAC Address of the iSCSI offload engine
+# none: No IP configuration set for the iSCSI offload engine
+# dhcp: iSCSI offload engine configured for DHCP
+# ip: iSCSI offload engine configured with static IP address <ipaddr>
