Subject: Initial redhat build
|
||||
|
||||
This patch introduces redhat build structure in redhat subdirectory. In addition,
|
||||
several issues are fixed in QEMU tree:
|
||||
|
||||
- Change of app name for sasl_server_init in VNC code from qemu to qemu-kvm
|
||||
- As we use qemu-kvm as name in all places, this is updated to be consistent
|
||||
- Man page renamed from qemu to qemu-kvm
|
||||
- man page is installed using make install so we have to fix it in qemu tree
|
||||
|
||||
We disable make check due to issues with some of the tests.
|
||||
|
||||
This rebase is based on qemu-kvm-7.1.0-7.el9

+QEMU tracing using systemtap-initscript
|
||||
+---------------------------------------
|
||||
+
|
||||
+You can capture QEMU trace data all the time using systemtap-initscript. This
|
||||
+uses SystemTap's flight recorder mode to trace all running guests to a
|
||||
+fixed-size buffer on the host. Old trace entries are overwritten by new
|
||||
+entries when the buffer size wraps.
|
||||
+
|
||||
+1. Install the systemtap-initscript package:
|
||||
+ # yum install systemtap-initscript
|
||||
+
|
||||
+2. Install the systemtap scripts and the conf file:
|
||||
+ # cp /usr/share/qemu-kvm/systemtap/script.d/qemu_kvm.stp /etc/systemtap/script.d/
|
||||
+ # cp /usr/share/qemu-kvm/systemtap/conf.d/qemu_kvm.conf /etc/systemtap/conf.d/
|
||||
+
|
||||
+The set of trace events to enable is given in qemu_kvm.stp. This SystemTap
|
||||
+script can be customized to add or remove trace events provided in
|
||||
+/usr/share/systemtap/tapset/qemu-kvm-simpletrace.stp.
|
||||
+
|
||||
+SystemTap customizations can be made to qemu_kvm.conf to control the flight
|
||||
+recorder buffer size and whether to store traces in memory only or disk too.
|
||||
+See stap(1) for option documentation.
|
||||
+
|
||||
+3. Start the systemtap service.
|
||||
+ # service systemtap start qemu_kvm
|
||||
+
|
||||
+4. Make the service start at boot time.
|
||||
+ # chkconfig systemtap on
|
||||
+
|
||||
+5. Confirm that the service works.
|
||||
+ # service systemtap status qemu_kvm
|
||||
+ qemu_kvm is running...
|
||||
+
|
||||
+When you want to inspect the trace buffer, perform the following steps:
|
||||
+
|
||||
+1. Dump the trace buffer.
|
||||
+ # staprun -A qemu_kvm >/tmp/trace.log
|
||||
+
|
||||
+2. Start the systemtap service because the preceding step stops the service.
|
||||
+ # service systemtap start qemu_kvm
|
||||
+
|
||||
+3. Translate the trace record to readable format.
|
||||
+ # /usr/share/qemu-kvm/simpletrace.py --no-header /usr/share/qemu-kvm/trace-events /tmp/trace.log

Subject: Initial redhat build
|
||||
|
||||
This patch introduces redhat build structure in redhat subdirectory. In addition,
|
||||
several issues are fixed in QEMU tree:
|
||||
|
||||
- Change of app name for sasl_server_init in VNC code from qemu to qemu-kvm
|
||||
- As we use qemu-kvm as name in all places, this is updated to be consistent
|
||||
- Man page renamed from qemu to qemu-kvm
|
||||
- man page is installed using make install so we have to fix it in qemu tree
|
||||
|
||||

+QEMU tracing using systemtap-initscript
|
||||
+---------------------------------------
|
||||
+
|
||||
+You can capture QEMU trace data all the time using systemtap-initscript. This
|
||||
+uses SystemTap's flight recorder mode to trace all running guests to a
|
||||
+fixed-size buffer on the host. Old trace entries are overwritten by new
|
||||
+entries when the buffer size wraps.
|
||||
+
|
||||
+1. Install the systemtap-initscript package:
|
||||
+ # yum install systemtap-initscript
|
||||
+
|
||||
+2. Install the systemtap scripts and the conf file:
|
||||
+ # cp /usr/share/qemu-kvm/systemtap/script.d/qemu_kvm.stp /etc/systemtap/script.d/
|
||||
+ # cp /usr/share/qemu-kvm/systemtap/conf.d/qemu_kvm.conf /etc/systemtap/conf.d/
|
||||
+
|
||||
+The set of trace events to enable is given in qemu_kvm.stp. This SystemTap
|
||||
+script can be customized to add or remove trace events provided in
|
||||
+/usr/share/systemtap/tapset/qemu-kvm-simpletrace.stp.
|
||||
+
|
||||
+SystemTap customizations can be made to qemu_kvm.conf to control the flight
|
||||
+recorder buffer size and whether to store traces in memory only or disk too.
|
||||
+See stap(1) for option documentation.
|
||||
+
|
||||
+3. Start the systemtap service.
|
||||
+ # service systemtap start qemu_kvm
|
||||
+
|
||||
+4. Make the service start at boot time.
|
||||
+ # chkconfig systemtap on
|
||||
+
|
||||
+5. Confirm that the service works.
|
||||
+ # service systemtap status qemu_kvm
|
||||
+ qemu_kvm is running...
|
||||
+
|
||||
+When you want to inspect the trace buffer, perform the following steps:
|
||||
+
|
||||
+1. Dump the trace buffer.
|
||||
+ # staprun -A qemu_kvm >/tmp/trace.log
|
||||
+
|
||||
+2. Start the systemtap service because the preceding step stops the service.
|
||||
+ # service systemtap start qemu_kvm
|
||||
+
|
||||
+3. Translate the trace record to readable format.
|
||||
+ # /usr/share/qemu-kvm/simpletrace.py --no-header /usr/share/qemu-kvm/trace-events /tmp/trace.log

Subject: globally limit the maximum number of CPUs
|
||||
|
||||
We now globally limit the number of VCPUs.
|
||||
Especially, there is no way one can specify more than
|
||||
max_cpus VCPUs for a VM.
|
||||
|
||||
This allows us the restore the ppc max_cpus limitation to the upstream
|
||||
default and minimize the ppc hack in kvm-all.c.

qcow2 v3 has been around for a long time (since QEMU 1.1/RHEL 7), so
|
||||
there is no real reason any more to use it. People still using it might
|
||||
do so unintentionally. Warn about it and suggest upgrading during the
|
||||
RHEL 9 timeframe so that the code can possibly be disabled in RHEL 10.
|
||||
|
||||
The warning is restricted to read-write mode and the system emulator.
|
||||
The primary motivation for not having it in qemu-img is that 'qemu-img
|
||||
amend' for upgrades would warn otherwise. It also avoids having to make
|
||||
too many changes to the test suite.
|
||||
|
||||
bdrv_uses_whitelist() is used as a proxy for deciding whether we are
|
||||
running in a tool or the system emulator. This is not entirely clean,
|
||||
but it's what is available and the same function qcow2_do_open() already
|
||||
uses it this way for another warning.

|

We need a fix for RHEL 7.4 and 7.3.z, but unfortunately upstream isn't
|
||||
ready. If it were, the changes will be too invasive. To have an idea:
|
||||
|
||||
https://lists.gnu.org/archive/html/qemu-devel/2017-05/msg05400.html
|
||||
|
||||
is an incomplete attempt to fix part of the issue, and the remaining
|
||||
work unfortunately involve even more complex changes.
|
||||
|
||||
As a band-aid, this partially reverts the effect of ef8875b
|
||||
(virtio-scsi: Remove op blocker for dataplane, since v2.7). We cannot
|
||||
simply revert that commit as a whole because we already shipped it in
|
||||
qemu-kvm-rhev 7.3, since when, block jobs has been possible. We should
|
||||
only block what has been broken. Also, faithfully reverting the above
|
||||
commit means adding back the removed op blocker, but that is not enough,
|
||||
because it still crashes when inserting media into an initially empty
|
||||
scsi-cd.
|
||||
|
||||
All in all, scsi-cd on virtio-scsi-dataplane has basically been unusable
|
||||
unless the scsi-cd never enters an empty state, so, disable it
|
||||
altogether. Otherwise it would be much more difficult to avoid
|
||||
crashing.

Bugzilla: https://bugzilla.redhat.com/show_bug.cgi?id=2143585
|

Upstream Status: n/a (rhel-only)

|

Add the compatibility handling for the rebase from QEMU 7.1 to 7.2,
|
||||
i.e. the settings from ccw_machine_7_1_class_options() and
|
||||
ccw_machine_7_1_instance_options() to the rhel9.1.0 machine type
|
||||
(earlier settings have been added by previous rebases already).

hw_compat_rhel_8_4 has an issue: it affects only "virtio-net-pci"
|
||||
but not "virtio-net-pci-transitional" and
|
||||
"virtio-net-pci-non-transitional". The solution is to use the
|
||||
"virtio-net-pci-base" type in compat_props.
|
||||
|
||||
An equivalent fix will be submitted for hw_compat_5_2 upstream.

Add pc_rhel_8_5_compat as the merge of pc_compat_6_1 and pc_compat_6_0
|
||||
(since 8.5 was based on 6.0).
|
||||
|
||||
Note, x-keep-pci-slot-hpc flipped back and forward, leaving it out
|
||||
looks like it leaves us with the original.

Add compatibility handling for the rhel8.5.0 machine type (and
|
||||
recursively older, of course).
|
||||
|
||||
Based on the following upstream commits:
|
||||
|
||||
463e50da8b - s390x/cpumodel: Bump up QEMU model to a stripped-down IBM z14 GA2
|
||||
30e398f796 - s390x/cpumodel: Add more feature to gen16 default model
|
||||
4a0af2930a - machine: Prefer cores over sockets in smp parsing since 6.2
|
||||
2b52619994 - machine: Move smp_prefer_sockets to struct SMPCompatProps

RH-MergeRequest: 176: Enable KVM AMX support

|
||||
|
||||
Some AMD processors expose the PKRU extended save state even if they do not have
|
||||
the related PKU feature in CPUID. Worse, when they do they report a size of
|
||||
64, whereas the expected size of the PKRU extended save state is 8, therefore
|
||||
the esa->size == eax assertion does not hold.
|
||||
|
||||
The state is already ignored by KVM_GET_SUPPORTED_CPUID because it
|
||||
was not enabled in the host XCR0. However, QEMU kvm_cpu_xsave_init()
|
||||
runs before QEMU invokes arch_prctl() to enable dynamically-enabled
|
||||
save states such as XTILEDATA, and KVM_GET_SUPPORTED_CPUID hides save
|
||||
states that have yet to be enabled. Therefore, kvm_cpu_xsave_init()
|
||||
needs to consult the host CPUID instead of KVM_GET_SUPPORTED_CPUID,
|
||||
and dies with an assertion failure.
|
||||
|
||||
When setting up the ExtSaveArea array to match the host, ignore features that
|
||||
KVM does not report as supported. This will cause QEMU to skip the incorrect
|
||||
CPUID leaf instead of tripping the assertion.
|
||||

|
||||
|
||||
Add flags to io_writev and introduce io_flush as optional callback to
|
||||
QIOChannelClass, allowing the implementation of zero copy writes by
|
||||
subclasses.
|
||||
|
||||
How to use them:
|
||||
- Write data using qio_channel_writev*(...,QIO_CHANNEL_WRITE_FLAG_ZERO_COPY),
|
||||
- Wait write completion with qio_channel_flush().
|
||||
|
||||
Notes:
|
||||
As some zero copy write implementations work asynchronously, it's
|
||||
recommended to keep the write buffer untouched until the return of
|
||||
qio_channel_flush(), to avoid the risk of sending an updated buffer
|
||||
instead of the buffer state during write.
|
||||
|
||||
As io_flush callback is optional, if a subclass does not implement it, then:
|
||||
- io_flush will return 0 without changing anything.
|
||||
|
||||
Also, some functions like qio_channel_writev_full_all() were adapted to
|
||||
receive a flag parameter. That allows shared code between zero copy and
|
||||
non-zero copy writev, and also an easier implementation on new flags.

|
||||
|
||||
For using MSG_ZEROCOPY, there are two steps:
|
||||
1 - io_writev() the packet, which enqueues the packet for sending, and
|
||||
2 - io_flush(), which gets confirmation that all packets got correctly sent
|
||||
|
||||
Currently, if MSG_ZEROCOPY is used to send packets over IPV6, no error will
|
||||
be reported in (1), but it will fail in the first time (2) happens.
|
||||
|
||||
This happens because (2) currently checks for cmsg_level & cmsg_type
|
||||
associated with IPV4 only, before reporting any error.
|
||||
|
||||
Add checks for cmsg_level & cmsg_type associated with IPV6, and thus enable
|
||||
support for MSG_ZEROCOPY + IPV6

|

|
||||
If flush is called when no buffer was sent with MSG_ZEROCOPY, it currently
|
||||
returns 1. This return code should be used only when Linux fails to use
|
||||
MSG_ZEROCOPY on a lot of sendmsg().
|
||||
|
||||
Fix this by returning early from flush if no sendmsg(...,MSG_ZEROCOPY)
|
||||
was attempted.

|
||||
Somewhere between v6 and v7 the of the zero-copy-send patchset a crucial
|
||||
part of the flushing mechanism got missing: incrementing zero_copy_queued.
|
||||
|
||||
Without that, the flushing interface becomes a no-op, and there is no
|
||||
guarantee the buffer is really sent.
|
||||
|
||||
This can go as bad as causing a corruption in RAM during migration.

|
||||
|
||||
For CONFIG_LINUX, implement the new zero copy flag and the optional callback
|
||||
io_flush on QIOChannelSocket, but enables it only when MSG_ZEROCOPY
|
||||
feature is available in the host kernel, which is checked on
|
||||
qio_channel_socket_connect_sync()
|
||||
|
||||
qio_channel_socket_flush() was implemented by counting how many times
|
||||
sendmsg(...,MSG_ZEROCOPY) was successfully called, and then reading the
|
||||
socket's error queue, in order to find how many of them finished sending.
|
||||
Flush will loop until those counters are the same, or until some error occurs.
|
||||
|
||||
Notes on using writev() with QIO_CHANNEL_WRITE_FLAG_ZERO_COPY:
|
||||
1: Buffer
|
||||
- As MSG_ZEROCOPY tells the kernel to use the same user buffer to avoid copying,
|
||||
some caution is necessary to avoid overwriting any buffer before it's sent.
|
||||
If something like this happen, a newer version of the buffer may be sent instead.
|
||||
- If this is a problem, it's recommended to call qio_channel_flush() before freeing
|
||||
or re-using the buffer.
|
||||
|
||||
2: Locked memory
|
||||
- When using MSG_ZERCOCOPY, the buffer memory will be locked after queued, and
|
||||
unlocked after it's sent.
|
||||
- Depending on the size of each buffer, and how often it's sent, it may require
|
||||
a larger amount of locked memory than usually available to non-root user.
|
||||
- If the required amount of locked memory is not available, writev_zero_copy
|
||||
will return an error, which can abort an operation like migration,
|
||||
- Because of this, when an user code wants to add zero copy as a feature, it
|
||||
requires a mechanism to disable it, so it can still be accessible to less
|
||||
privileged users.

During implementation of MSG_ZEROCOPY feature, a lot of #ifdefs were
|
||||
introduced, particularly at qio_channel_socket_writev().
|
||||
|
||||
Rewrite some of those changes so it's easier to read.
|

|

Also, introduce an assert to help detect incorrect zero-copy usage is when
|
||||
it's disabled on build.

vhost-vsock device in RHEL 8 kernels doesn't support seqpacket.
|

To avoid problems when migrating a VM from RHEL 9 host, we need to
|

disable it in rhel8-* machine types.

Manual revert of commit 70d3924521c9bfd912bcf1a1fc76f49eb377de46, since

the directory structure looks different from rhel-av-8.4.0.z where

this commit is taken from. Besides, x86_64-softmmu.mak looks totally

different and should not be affected by this reversal.

|
||||
|
||||
This reverts commit a7f523c7d114d445c5d83aecdba3efc038e5a692.
|
||||
|
||||
The nested event loop is broken by design. It's only user was removed.
|
||||
Drop the code as well so that nobody ever tries to use it again.
|
||||
|
||||
I had to fix a couple of trivial conflicts around return values because
|
||||
of 025faa872bcf ("vhost-user: stick to -errno error return convention").

|
||||
|
||||
This reverts commit db8a3772e300c1a656331a92da0785d81667dc81.
|
||||
|
||||
Motivation : this is breaking vhost-user with DPDK as reported in [0].

||||

||||

|
||||

|
||||

|
||||
Received unexpected msg type. Expected 22 received 11
|
||||
Fail to update device iotlb
|
||||
Received unexpected msg type. Expected 11 received 22
|
||||
vhost VQ 0 ring restore failed: -71: Protocol error (71)
|
||||
unable to start vhost net: 71: falling back on userspace virtio
|
||||
|
||||
The failing sequence that leads to the first error is :
|
||||
- QEMU sends a VHOST_USER_GET_STATUS (40) request to DPDK on the master
|
||||
socket
|
||||
- QEMU starts a nested event loop in order to wait for the
|
||||
VHOST_USER_GET_STATUS response and to be able to process messages from
|
||||
the slave channel
|
||||
- DPDK sends a couple of legitimate IOTLB miss messages on the slave
|
||||
channel
|
||||
- QEMU processes each IOTLB request and sends VHOST_USER_IOTLB_MSG (22)
|
||||
updates on the master socket
|
||||
- QEMU assumes to receive a response for the latest VHOST_USER_IOTLB_MSG
|
||||
but it gets the response for the VHOST_USER_GET_STATUS instead
|
||||
|
||||
The subsequent errors have the same root cause : the nested event loop
|
||||
breaks the order by design. It lures QEMU to expect responses to the
|
||||
latest message sent on the master socket to arrive first.
|
||||
|
||||
Since this was only needed for DAX enablement which is still not merged
|
||||
upstream, just drop the code for now. A working solution will have to
|
||||
be merged later on. Likely protect the master socket with a mutex
|
||||
and service the slave channel with a separate thread, as discussed with
|
||||
Maxime in the mail thread below.

Test: 'kvm unit test ./run_tests.sh -g debug' does not SIGSEV anymore
|
||||
|
||||
After commit 4e4fa6c12d ("accel/tcg: Complete cpu initialization
|
||||
before registration"), it looks the CPUJumpCache pointer can be NULL.
|
||||
This causes a SIGSEV when running debug-wp-migration kvm unit test.
|
||||
|
||||
At the first place it should be clarified why this TCG code is called
|
||||
with KVM acceleration. This may hide another bug.

acpi: fix OEM ID/OEM Table ID padding
|
||||
|
||||
Commit [2] broke original '\0' padding of OEM ID and OEM Table ID
|
||||
fields in headers of ACPI tables. While it doesn't have impact on
|
||||
default values since QEMU uses 6 and 8 characters long values
|
||||
respectively, it broke usecase where IDs are provided on QEMU CLI.
|
||||
It shouldn't affect guest (but may cause licensing verification
|
||||
issues in guest OS).
|
||||
One of the broken usecases is user supplied SLIC table with IDs
|
||||
shorter than max possible length, where [2] mangles IDs with extra
|
||||
spaces in RSDT and FADT tables whereas guest OS expects those to
|
||||
mirror the respective values of the used SLIC table.
|
||||
|
||||
Fix it by replacing whitespace padding with '\0' padding in
|
||||
accordance with [1] and expectations of guest OS
|
||||
|
||||
1) ACPI spec, v2.0b
|
||||
17.2 AML Grammar Definition
|
||||
...
|
||||
//OEM ID of up to 6 characters. If the OEM ID is
|
||||
//shorter than 6 characters, it can be terminated
|
||||
//with a NULL character.
|
||||

||||

acpi: fix QEMU crash when started with SLIC table
|

|
||||
if QEMU is started with used provided SLIC table blob,
|
||||
|
||||
-acpitable sig=SLIC,oem_id='CRASH ',oem_table_id="ME",oem_rev=00002210,asl_compiler_id="",asl_compiler_rev=00000000,data=/dev/null
|

it will assert with:

|
||||
hw/acpi/aml-build.c:61:build_append_padded_str: assertion failed: (len <= maxlen)
|
||||
|
||||
and following backtrace:
|
||||
|
||||
...
|
||||
build_append_padded_str (array=0x555556afe320, str=0x555556afdb2e "CRASH ME", maxlen=0x6, pad=0x20) at hw/acpi/aml-build.c:61

|
||||
...
|

|

which happens due to acpi_table_begin() expecting NULL terminated

oem_id and oem_table_id strings, which is normally the case, but

in case of user provided SLIC table, oem_id points to table's blob
|
||||
directly and as result oem_id became longer than expected.
|
||||
|
||||
Fix issue by handling oem_id consistently and make acpi_get_slic_oem()
|
||||
return NULL terminated strings.
|
||||
|
||||
PS:
|
||||
After [1] refactoring, oem_id semantics became inconsistent, where
|
||||
NULL terminated string was coming from machine and old way pointer
|
||||
into byte array coming from -acpitable option. That used to work
|
||||
since build_header() wasn't expecting NULL terminated string and
|
||||
blindly copied the 1st 6 bytes only.
|
||||
|
||||
However commit [2] broke that by replacing build_header() with
|
||||
acpi_table_begin(), which was expecting NULL terminated string
|
||||
and was checking oem_id size.
|
||||
|
||||

|
||||
2)

RH-Commit: [1/2] c5b9cdf5791cd856207b7df7e2ef5df360ec8de4
|
||||
|
||||
vmstate_acpi_pcihp_use_acpi_index() was expecting AcpiPciHpState
|
||||
as state but it actually received PIIX4PMState, because
|
||||
VMSTATE_PCI_HOTPLUG is a macro and not another struct.
|
||||
So it ended up accessing random pointer, which resulted
|
||||
in 'false' return value and acpi_index field wasn't ever
|
||||
sent.
|
||||
|
||||
However in 7.0 that pointer de-references to value > 0, and
|
||||
destination QEMU starts to expect the field which isn't
|
||||
sent in migratioon stream from older QEMU (6.2 and older).
|
||||
As result migration fails with:
|
||||
qemu-system-x86_64: Missing section footer for 0000:00:01.3/piix4_pm
|
||||
qemu-system-x86_64: load of migration failed: Invalid argument
|
||||
|
||||
In addition with QEMU-6.2, destination due to not expected
|
||||
state, also never expects the acpi_index field in migration
|
||||
stream.
|
||||
|
||||
Q35 is not affected as it always sends/expects the field as
|
||||
long as acpi based PCI hotplug is enabled.
|
||||
|
||||
Fix issue by introducing compat knob to never send/expect
|
||||
acpi_index in migration stream for 6.2 and older PC machine
|
||||
types and always send it for 7.0 and newer PC machine types.

acpi: pcihp: pcie: set power on cap on parent slot
|
||||
|
||||
on creation a PCIDevice has power turned on at the end of pci_qdev_realize()
|
||||
however later on if PCIe slot isn't populated with any children
|
||||
it's power is turned off. It's fine if native hotplug is used
|
||||
as plug callback will power slot on among other things.
|
||||
However when ACPI hotplug is enabled it replaces native PCIe plug
|
||||
callbacks with ACPI specific ones (acpi_pcihp_device_*plug_cb) and
|
||||
as result slot stays powered off. It works fine as ACPI hotplug
|
||||
on guest side takes care of enumerating/initializing hotplugged
|
||||
device. But when later guest is migrated, call chain introduced by]
|
||||
commit d5daff7d312 (pcie: implement slot power control for pcie root ports)
|
||||
|
||||
pcie_cap_slot_post_load()
|
||||
-> pcie_cap_update_power()
|
||||
-> pcie_set_power_device()
|
||||
-> pci_set_power()
|
||||
-> pci_update_mappings()
|
||||
|
||||
will disable earlier initialized BARs for the hotplugged device
|
||||
in powered off slot due to commit 23786d13441 (pci: implement power state)
|
||||
which disables BARs if power is off.
|
||||
|
||||
Fix it by setting PCI_EXP_SLTCTL_PCC to PCI_EXP_SLTCTL_PWR_ON
|
||||
on slot (root port/downstream port) at the time a device
|
||||
hotplugged into it. As result PCI_EXP_SLTCTL_PWR_ON is migrated
|
||||
to target and above call chain keeps device plugged into it
|
||||
powered on.

When bus is looked up on a pci write, we didn't
|
||||
validate that the lookup succeeded.
|
||||
Fuzzers thus can trigger QEMU crash by dereferencing the NULL
|
||||
bus pointer.

aio-wait: switch to smp_mb__after_rmw()
|
||||
|
||||
The barrier comes after an atomic increment, so it is enough to use
|
||||
smp_mb__after_rmw(); this avoids a double barrier on x86 systems.

aio_wait_kick: add missing memory barrier
|
||||
|
||||
It seems that aio_wait_kick always required a memory barrier
|
||||
or atomic operation in the caller, but nobody actually
|
||||
took care of doing it.
|
||||
|
||||
Let's put the barrier in the function instead, and pair it
|
||||
with another one in AIO_WAIT_WHILE. Read aio_wait_kick()
|
||||
comment for further explanation.

async: avoid use-after-free on re-entrancy guard
|
||||
|
||||
A BH callback can free the BH, causing a use-after-free in aio_bh_call.
|
||||
Fix that by keeping a local copy of the re-entrancy guard pointer.

RH-Commit: [1/1] b5a1047750af32c0a261b8385ea0e819eb16681a
|
||||
|
||||
It is currently not possible yet to use "memory-backend-memfd" on s390x
|
||||
with hugepages enabled. This problem is caused by qemu_maxrampagesize()
|
||||
not taking memory-backend-memfd objects into account yet, so the code
|
||||
in s390_memory_init() fails to enable the huge page support there via
|
||||
s390_set_max_pagesize(). Fix it by generalizing the code, so that it
|
||||
looks at qemu_ram_pagesize(memdev->mr.ram_block) instead of re-trying
|
||||
to get the information from the filesystem.

RH-Commit: [12/16] ea9a433dc01d1b8539a2d4ea12887f2a3ce830ea (sgarzarella/qemu-kvm-c-9-s)
|
||||
|
||||
We only need to call both the BlockDriver's callback and the parent
|
||||
callbacks when going from undrained to drained or vice versa. A second
|
||||
drain section doesn't make a difference for the driver or the parent,
|
||||
they weren't supposed to send new requests before and after the second
|
||||
drain.
|
||||
|
||||
One thing that gets in the way is the 'ignore_bds_parents' parameter in
|
||||
bdrv_do_drained_begin_quiesce() and bdrv_do_drained_end(): It means that
|
||||
bdrv_drain_all_begin() increases bs->quiesce_counter, but does not
|
||||
quiesce the parent through BdrvChildClass callbacks. If an additional
|
||||
drain section is started now, bs->quiesce_counter will be non-zero, but
|
||||
we would still need to quiesce the parent through BdrvChildClass in
|
||||
order to keep things consistent (and unquiesce it on the matching
|
||||
bdrv_drained_end(), even though the counter would not reach 0 yet as
|
||||
long as the bdrv_drain_all() section is still active).
|
||||
|
||||
Instead of keeping track of this, let's just get rid of the parameter.
|
||||
It was introduced in commit 6cd5c9d7b2d as an optimisation so that
|
||||
during bdrv_drain_all(), we wouldn't recursively drain all parents up to
|
||||
the root for each node, resulting in quadratic complexity. As it happens,
|
||||
calling the callbacks only once solves the same problem, so as of this
|
||||
patch, we'll still have O(n) complexity and ignore_bds_parents is not
|
||||
needed any more.
|
||||
|
||||
This patch only ignores the 'ignore_bds_parents' parameter. It will be
|
||||
removed in a separate patch.

RH-Commit: [2/5] 1d86ce8398e4ab66e308a686f9855c963e52b0a9
|
||||
|
||||
When processing vectored guest requests that are not aligned to the
|
||||
storage request alignment, we pad them by adding head and/or tail
|
||||
buffers for a read-modify-write cycle.
|
||||
|
||||
The guest can submit I/O vectors up to IOV_MAX (1024) in length, but
|
||||
with this padding, the vector can exceed that limit. As of
|
||||
4c002cef0e9abe7135d7916c51abce47f7fc1ee2 ("util/iov: make
|
||||
qemu_iovec_init_extended() honest"), we refuse to pad vectors beyond the
|
||||
limit, instead returning an error to the guest.
|
||||
|
||||
To the guest, this appears as a random I/O error. We should not return
|
||||
an I/O error to the guest when it issued a perfectly valid request.
|
||||
|
||||
Before 4c002cef0e9abe7135d7916c51abce47f7fc1ee2, we just made the vector
|
||||
longer than IOV_MAX, which generally seems to work (because the guest
|
||||
assumes a smaller alignment than we really have, file-posix's
|
||||
raw_co_prw() will generally see bdrv_qiov_is_aligned() return false, and
|
||||
so emulate the request, so that the IOV_MAX does not matter). However,
|
||||
that does not seem exactly great.
|
||||
|
||||
I see two ways to fix this problem:
|
||||
1. We split such long requests into two requests.
|
||||
2. We join some elements of the vector into new buffers to make it
|
||||
shorter.
|
||||
|
||||
I am wary of (1), because it seems like it may have unintended side
|
||||
effects.
|
||||
|
||||
(2) on the other hand seems relatively simple to implement, with
|
||||
hopefully few side effects, so this patch does that.
|
||||
|
||||
To do this, the use of qemu_iovec_init_extended() in bdrv_pad_request()
|
||||
is effectively replaced by the new function bdrv_create_padded_qiov(),
|
||||
which not only wraps the request IOV with padding head/tail, but also
|
||||
ensures that the resulting vector will not have more than IOV_MAX
|
||||
elements. Putting that functionality into qemu_iovec_init_extended() is
|
||||
infeasible because it requires allocating a bounce buffer; doing so
|
||||
would require many more parameters (buffer alignment, how to initialize
|
||||
the buffer, and out parameters like the buffer, its length, and the
|
||||
original elements), which is not reasonable.
|
||||
|
||||
Conversely, it is not difficult to move qemu_iovec_init_extended()'s
|
||||
functionality into bdrv_create_padded_qiov() by using public
|
||||
qemu_iovec_* functions, so that is what this patch does.
|
||||
|
||||
Because bdrv_pad_request() was the only "serious" user of
|
||||
qemu_iovec_init_extended(), the next patch will remove the latter
|
||||
function, so the functionality is not implemented twice.

RH-Commit: [15/16] 5fc7d6b703a2d6c1118d875056f0afbd6ba5cca9 (sgarzarella/qemu-kvm-c-9-s)
|
||||
|
||||
In order to make sure that bdrv_replace_child_noperm() doesn't have to
|
||||
poll any more, get rid of the bdrv_parent_drained_begin_single() call.
|
||||
|
||||
This is possible now because we can require that the parent is already
|
||||
drained through the child in question when the function is called and we
|
||||
don't call the parent drain callbacks more than once.
|
||||
|
||||
The additional drain calls needed in callers cause the test case to run
|
||||
its code in the drain handler too early (bdrv_attach_child() drains
|
||||
now), so modify it to only enable the code after the test setup has
|
||||
completed.

child nodes of base that we're not even interested in), use a normal

drain for base, which automatically drains all of the parents, too.

||||
accounting for the additional complexity in the drain mechanism itself.
|
||||
|
||||
Simplify the code by switching to draining the individual nodes that are
|
||||
already managed in the BlockReopenQueue anyway.

|
||||
|
||||
The next patch adds a parent drain to bdrv_attach_child_common(), which
|
||||
shouldn't be, but is currently called from coroutines in some cases (e.g.
|
||||
.bdrv_co_create implementations generally open new nodes). Therefore,
|
||||
the assertion that we're not in a coroutine doesn't hold true any more.
|
||||
|
||||
We could just remove the assertion because there is nothing in the
|
||||
function that should be in conflict with running in a coroutine, but
|
||||
just to be on the safe side, we can reverse the caller relationship
|
||||
between bdrv_do_drained_begin() and bdrv_do_drained_begin_quiesce() so
|
||||
that the latter also just drops out of coroutine context and we can
|
||||
still be certain in the future that any drain code doesn't run in
|
||||
coroutines.
|
||||
|
||||
As a nice side effect, the structure of bdrv_do_drained_begin() is now
|
||||
symmetrical with bdrv_do_drained_end().

RH-Commit: [5/5] f9188bd089d6c67185ea1accde20d491a2ed3193
|
||||
|
||||
bdrv_pad_request() relies on requests' lengths not to exceed SIZE_MAX,
|
||||
which bdrv_check_qiov_request() does not guarantee.
|
||||
|
||||
bdrv_check_request32() however will guarantee this, and both of
|
||||
bdrv_pad_request()'s callers (bdrv_co_preadv_part() and
|
||||
bdrv_co_pwritev_part()) already run it before calling
|
||||
bdrv_pad_request(). Therefore, bdrv_pad_request() can safely call
|
||||
bdrv_check_request32() without expecting error, too.
|
||||
|
||||
In effect, this patch will not change guest-visible behavior. It is a
|
||||
clean-up to tighten a condition to match what is guaranteed by our
|
||||
callers, and which exists purely to show clearly why the subsequent
|
||||
assertion (`assert(*bytes <= SIZE_MAX)`) is always true.
|
||||
|
||||
Note there is a difference between the interfaces of
|
||||
bdrv_check_qiov_request() and bdrv_check_request32(): The former takes
|
||||
an errp, the latter does not, so we can no longer just pass
|
||||
&error_abort. Instead, we need to check the returned value. While we
|
||||
do expect success (because the callers have already run this function),
|
||||
an assert(ret == 0) is not much simpler than just to return an error if
|
||||
it occurs, so let us handle errors by returning them up the stack now.

RH-Commit: [1/12] be551e83f426e620e673302198b51368bfd324ce (hreitz/qemu-kvm-c-9-s)
|
||||
|
||||
When a block driver supports obtaining format-specific information, but
|
||||
that object only contains optional fields, it is possible that none of
|
||||
them are present, so that dump_qobject() (called by
|
||||
bdrv_image_info_specific_dump()) will not print anything.
|
||||
|
||||
The callers of bdrv_image_info_specific_dump() put a header above this
|
||||
information ("Format specific information:\n"), which will look strange
|
||||
when there is nothing below. Modify bdrv_image_info_specific_dump() to
|
||||
print this header instead of its callers, and only if there is indeed
|
||||
something to be printed.

bdrv_subtree_drained_end() requires the caller to hold the AioContext
|
||||
lock for the drained node. Not doing this for nodes outside of the main
|
||||
AioContext leads to crashes when AIO_WAIT_WHILE() needs to wait and
|
||||
tries to temporarily release the lock.

|
||||
|
||||
bdrv_refresh_limits() recurses down to the node's children. That does
|
||||
not seem necessary: When we refresh limits on some node, and then
|
||||
recurse down and were to change one of its children's BlockLimits, then
|
||||
that would mean we noticed the changed limits by pure chance. The fact
|
||||
that we refresh the parent's limits has nothing to do with it, so the
|
||||
reason for the change probably happened before this point in time, and
|
||||
we should have refreshed the limits then.
|
||||
|
||||
Consequently, we should actually propagate block limits changes upwards,
|
||||
not downwards. That is a separate and pre-existing issue, though, and
|
||||
so will not be addressed in this patch.
|
||||
|
||||
The problem with recursing is that bdrv_refresh_limits() is not atomic.
|
||||
It begins with zeroing BDS.bl, and only then sets proper, valid limits.
|
||||
If we do not drain all nodes whose limits are refreshed, then concurrent
|
||||
I/O requests can encounter invalid request_alignment values and crash
|
||||
qemu. Therefore, a recursing bdrv_refresh_limits() requires the whole
|
||||
subtree to be drained, which is currently not ensured by most callers.
|
||||
|
||||
A non-recursive bdrv_refresh_limits() only requires the node in question
|
||||
to not receive I/O requests, and this is done by most callers in some
|
||||
way or another:
|
||||
- bdrv_open_driver() deals with a new node with no parents yet
|
||||
- bdrv_set_file_or_backing_noperm() acts on a drained node
|
||||
- bdrv_reopen_commit() acts only on drained nodes
|
||||
- bdrv_append() should in theory require the node to be drained; in
|
||||
practice most callers just lock the AioContext, which should at least
|
||||
be enough to prevent concurrent I/O requests from accessing invalid
|
||||
limits
|
||||
|
||||
So we can resolve the bug by making bdrv_refresh_limits() non-recursive.

Subject: [PATCH 17/31] block: Remove drained_end_counter
|

|

RH-Commit: [5/16] 5589e3f05dece5394a05641f7f42096e8dc62bdb (sgarzarella/qemu-kvm-c-9-s)
|
||||
|
||||
drained_end_counter is unused now, nobody changes its value any more. It
|
||||
can be removed.
|
||||
|
||||
In cases where we had two almost identical functions that only differed
|
||||
in whether the caller passes drained_end_counter, or whether they would
|
||||
poll for a local drained_end_counter to reach 0, these become a single
|
||||
function.

RH-Commit: [13/16] 1ed88d975a9569bffeb33ad847874417780ce408 (sgarzarella/qemu-kvm-c-9-s)
|
||||
|
||||
ignore_bds_parents is now ignored during drain_begin and drain_end, so
|
||||
we can just remove it there. It is still a valid optimisation for
|
||||
drain_all in bdrv_drained_poll(), so leave it around there.

RH-Commit: [11/16] d92f5041cceeeec49a65441b22d20f692c0f1c77 (sgarzarella/qemu-kvm-c-9-s)
|
||||
|
||||
Subtree drains are not used any more. Remove them.
|
||||
|
||||
After this, BdrvChildClass.attach/detach() don't poll any more.

Subject: [PATCH 16/31] block: Revert .bdrv_drained_begin/end to

non-coroutine_fn

RH-MergeRequest: 135: block: Simplify drain to prevent QEMU from crashing during snapshot

RH-Commit: [4/16] 86d6049e40a99604e414c2572b67f74b85868832 (sgarzarella/qemu-kvm-c-9-s)
|
||||
|
||||
Polling during bdrv_drained_end() can be problematic (and in the future,
|
||||
we may get cases for bdrv_drained_begin() where polling is forbidden,
|
||||
and we don't care about already in-flight requests, but just want to
|
||||
prevent new requests from arriving).
|
||||
|
||||
The .bdrv_drained_begin/end callbacks running in a coroutine is the only
|
||||
reason why we have to do this polling, so make them non-coroutine
|
||||
callbacks again. None of the callers actually yield any more.
|
||||
|
||||
This means that bdrv_drained_end() effectively doesn't poll any more,
|
||||
even if AIO_WAIT_WHILE() loops are still there (their condition is false
|
||||
from the beginning). This is generally not a problem, but in
|
||||
test-bdrv-drain, some additional explicit aio_poll() calls need to be
|
||||
added because the test case wants to verify the final state after BHs
|
||||
have executed.

Subject: [PATCH 09/20] block: Split BlockNodeInfo off of ImageInfo

RH-MergeRequest: 145: Show protocol-level information in qemu-img info

RH-Commit: [4/12] fc8d69d549bb9a929db218b91697ee3ae95c1ff6 (hreitz/qemu-kvm-c-9-s)
|
||||
|
||||
ImageInfo sometimes contains flat information, and sometimes it does
|
||||
not. Split off a BlockNodeInfo struct, which only contains information
|
||||
about a single node and has no link to the backing image.
|
||||
|
||||
We do this so we can extend BlockNodeInfo to a BlockGraphInfo struct,
|
||||
which has links to all child nodes, not just the backing node. It would
|
||||
be strange to base BlockGraphInfo on ImageInfo, because then this
|
||||
extended struct would have two links to the backing node (one in
|
||||
BlockGraphInfo as one of all the child links, and one in ImageInfo).
|
||||
|
||||
Furthermore, it is quite common to ignore the backing-image field
|
||||
altogether: bdrv_query_image_info() does not set it, and
|
||||
bdrv_image_info_dump() does not evaluate it. That signals that we
|
||||
should have different structs for describing a single node and one that
|
||||
has a link to the backing image.
|
||||
|
||||
Still, bdrv_query_image_info() and bdrv_image_info_dump() are not
|
||||
changed too much in this patch. Follow-up patches will handle them.

RH-Commit: [1/2] da5a59eddff0dc10be7de8e291fa675143d11d73

|
||||
|
||||
The BlockBackend root child can change when aio_poll() is invoked. This
|
||||
happens when a temporary filter node is removed upon blockjob
|
||||
completion, for example.
|
||||
|
||||
Functions in block/block-backend.c must be aware of this when using a
|
||||
blk_bs() pointer across aio_poll() because the BlockDriverState refcnt
|
||||
may reach 0, resulting in a stale pointer.
|
||||
|
||||
One example is scsi_device_purge_requests(), which calls blk_drain() to
|
||||
wait for in-flight requests to cancel. If the backup blockjob is active,
|
||||
then the BlockBackend root child is a temporary filter BDS owned by the
|
||||
blockjob. The blockjob can complete during bdrv_drained_begin() and the
|
||||
last reference to the BDS is released when the temporary filter node is
|
||||
removed. This results in a use-after-free when blk_drain() calls
|
||||
bdrv_drained_end(bs) on the dangling pointer.
|
||||
|
||||
Explicitly hold a reference to bs across block APIs that invoke
|
||||
aio_poll().
