Message-ID: <9a31f486329e36bbe6f6156eb89d4d455fc0a7d8.1707394627.git.jdenemar@redhat.com>

Subject: [PATCH] Don't overwrite error message from 'virXPathNodeSet'
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit
'virXPathNodeSet' returns -1 only when 'ctxt' or 'xpath' are NULL or
when the 'xpath' string is invalid. Both are programming errors. It
doesn't make sense for the code to overwrite the error message for
anything supposedly more relevant.
The majority of calls to 'virXPathNodeSet' already didn't do this, so
this patch fixes the rest to prevent it from spreading again.

Subject: [PATCH] conf: Introduce dynamicMemslots attribute for virtio-mem
Introduced in v8.2.0-rc0~74^2~2, QEMU now allows setting
.dynamic-memslots attribute for virtio-mem-pci devices. When
turned on, it allows memory exposed to guest to be split into
multiple memslots and thus smaller memory footprint (see the
original commit for detailed explanation).
Therefore, introduce new <target/> attribute which will control
that QEMU knob.

'virNodeDeviceCapVPDParseCustomFields' to fix error reporting
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit
The errors raised in virNodeDeviceCapVPDParseCustomFields were actually
ignored by continuing the parse rather than raised.
Rather than just replace 'continue' by 'return -1' this patch refactors
the whole parser to simplify it as well as report reasonable errors.
Parsing of individual fields is done without XPath and is extracted into
a common helper.

e74d627bb3bc2684cbe3 refactored the code and started registering it, the
old logic which was clearing 'priv->nbdPort' in case when it was manually
specified was not removed.
This caused following problems:
- the port was not released after successful migration
- the port was released even when it was not allocated on failures
regarding the NBD server start
- the port was not released on other failures of the migration after
NBD server startup
To address this we remove the assumption that 'priv->nbdPort' is used
only for auto-allocated port and fill it only once the port is
allocated and make the caller of qemuMigrationDstStartNBDServer
responsible for releasing it.

Historically creating offline external snapshot required disk-only flag
as well. Now when user requests new snapshot for offline VM and at least
one disk is specified to use external snapshot we will no longer require
disk-only flag as all other not specified disk will use external
snapshots as well.

Subject: [PATCH] qemu_snapshot: fix detection if non-leaf snapshot isn't in
active chain
The condition was completely wrong. As per the comment for function
virDomainMomentIsAncestor() it checks that the first argument is
descendant of the second argument.
Consider the following snapshot tree for VM:
s1
|
+- s2
| |
| +- s3
|
+- s4
|
+- s5 (current)
When deleting s2 with the original code we checked if
virDomainMomentIsAncestor(s2, s5) which would return false basically for
any snapshot as s5 is leaf snapshot so no children.
When deleting s2 with fixed code we check if
virDomainMomentIsAncestor(s5, s2) which still returns false but when
deleting s4 it will correctly return true.
Before this fix it fails with the following error:
error: Failed to delete snapshot s2
error: invalid argument: could not find base disk source in disk source chain
After the fix it fails with correct error:
error: Failed to delete snapshot s2
error: unsupported configuration: deletion of non-leaf external snapshot that is not in active chain is not supported

Subject: [PATCH] remoteDispatchAuthPolkit: Fix lock ordering deadlock if
client closes connection during auth
Locks in following text:
A: virNetServer
B: virNetServerClient
C: daemonClientPrivate
'virNetServerSetClientAuthenticated' locks A then B
'remoteDispatchAuthPolkit' calls 'virNetServerSetClientAuthenticated'
while holding C.
If a client closes its connection 'virNetServerProcessClients' with the
lock A and B locked will call 'virNetServerClientCloseLocked' which will
try to dispose of the 'client' private data by:
ref(b);
unlock(b);
remoteClientFreePrivateCallbacks();
lock(b);
unref(b);
Unfortunately remoteClientFreePrivateCallbacks() tries lock C.
Thus the locks are held in the following order:
polkit auth: C -> A
connection close: A -> C
causing a textbook-example deadlock. To resolve it we can simply drop
lock 'C' before calling 'virNetServerSetClientAuthenticated' as the lock
is not needed any more.

Subject: [PATCH] remote_driver: Restore special behavior of
remoteDomainGetBlockIoTune()
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit
In v9.10.0-rc1~103 the remote driver was switched to g_auto() for
client RPC return parameters. But whilst doing so a small bug
slipped in: previously, when virDomainGetBlockIoTune() was called
with *nparams == 0, the function set *nparams to the number of
supported params and zero was returned (so that client can
allocate memory and call the API second time). IOW - the usual,
old style of APIs where we didn't want to allocate memory on
caller's behalf. But because of this bug, a negative one is
returned instead.

Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit
The case checks only the 'virPCIVPDReadVPDBytes' which is also tested
multiple times via 'virPCIVPDParse' as it's used to read the data, thus
having a special case for this is pointless.

None of the callers pass NULL, so the NULL check is pointless. Remove it
an remove the return value.
The function is exported only for use in 'virpcivpdtest' thus marking
the arguments as NONNULL is unnecessary.

MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit
The function always succeeded and after the removal of programing error
checks doesn't even have a 'return false' case. Additionally one of the
tests in 'virpcivpdtest' tested that this function never failed on wrong
data. Embrace this logic and remove the return value and adjust logging
to VIR_DEBUG level to avoid spamming logs.

Similarly to previous commit other specific fields which come from the

formatted via virBufferAsprintf.
Other static and safe strings used virBufferEscapeString instead of
virBufferAddLit.

Subject: [PATCH] virNodeDeviceCapVPDFormatCustom*: Escape unsanitized strings
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit
The custom field data is taken from PCI device data which can contain
any printable characters, and thus must be escaped when putting into
XML.
Originally, based on the comment and XML schema which was fixed in
previous commits the idea seemed to be that the parser would validate
that only characters which don't break the XML would be present but that
didn't seem to materialize.
Switch to proper escaping of the XML.

Subject: [PATCH] virPCIDeviceGetVPD: Fix multiple error handling bugs
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit
- fix passing of 'errno' to 'virReportSystemError'
The 'open' syscall returns '-1' and sets 'errno' on failure. The code
passed '-fd' as 'errno' rather than errno itself, thus always reporting
EPERM.
- don't overwrite errors when closing FD
Use VIR_AUTOCLOSE to avoid overwriting the errors from virPCIVPDParse.

Subject: [PATCH] virPCIVPDParseVPDLargeResourceFields: Refactor return logic
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit
Rewrite the conditions after exiting the parser so that they are easier
to understand. This partially decreases the granularity of "error"
messages as they are not strictly necessary albeit for debugging.
As it was already observed in this code the logic itself often does
something else than the comment claims, thus the code logic is
preserved.
Changes:
- any case when not all data was processed is aggregated together and
gets a common "error" message
- absence of 'checksum' field is checked separately
- helper variables are removed as they are no longer needed

expected. Move the check inside virPCIVPDReadVPDBytes and make it report
a proper error rather than just a combination of VIR_DEBUG inside the
function and a random VIR_INFO in the caller.

MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8

This is a synthetic case which tests the behaviour if the 'ro' or 'rw'
struct members are uninitialized, basically excercising only a pointless
programming-error NULL check in 'virPCIVPDResourceUpdateKeyword' as real
usage does always pass a proper pointer.

Subject: [PATCH] virt-admin: Add warning when connection to default daemon
fails
The admin connection defaults to the system-wide 'libvirtd' daemon to
manage (libvirtd:///system). As we've now switched to modular daemons
this will not work for most users out of the box:
$ virt-admin version
error: Failed to connect to the admin server
error: no valid connection
error: Failed to connect socket to '/run/user/1000/libvirt/libvirt-admin-sock': No such file or directory
As we don't want to assume which daemon the user wants to manage in the
modular topology there's no reasonable default to pick.
Give a hint to the users to use the '-c' if the connection to the
default URI fails:
$ virt-admin version
NOTE: Connecting to default daemon. Specify daemon using '-c' (e.g. virtqemud:///system)
error: Failed to connect to the admin server
error: no valid connection
error: Failed to connect socket to '/run/user/1000/libvirt/libvirt-admin-sock': No such file or directory
