Subject: [PATCH] Fix padding of encrypted data
|
||||
|
||||
If we are encoding a block of data that is 16 bytes in length,
|
||||
we cannot leave it as 16 bytes, we must pad it out to the next
|
||||
block boundary, 32 bytes. Without this padding, the decoder will
|
||||
incorrectly treat the last byte of plain text as the padding
|
||||
length, as it can't distinguish padded from non-padded data.
|
||||
|
||||
The problem exhibited itself when using a 16 byte passphrase
|
||||
for a LUKS volume
|
||||
|
||||
$ virsh secret-set-value 55806c7d-8e93-456f-829b-607d8c198367 \

|

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

Content-Transfer-Encoding: 8bit
|

|

We never release the reference on the GSource created for
|
||||
interrupting the main loop, nor do we remove it from the
|
||||
main context if our thread is woken up prior to the wakeup
|
||||
callback firing.
|
||||
|
||||
This can result in a leak of GSource objects, along with an
|
||||
ever growing list of GSources attached to the main context,
|
||||
which will gradually slow down execution of the loop, as
|
||||
several operations are O(N) for the number of attached GSource
|
||||
objects.

|

|
||||
The root cause is a bad assumption in the virNetClientIOEventLoop
|
||||
method. This method is run by whichever thread currently owns the
|
||||
buck, and is responsible for handling I/O. Inside a for(;;) loop,
|
||||
this method creates a temporary GSource, adds it to the event loop
|
||||
and runs g_main_loop_run(). When I/O is ready, the GSource callback
|
||||
(virNetClientIOEventFD) will fire and call g_main_loop_quit(), and
|
||||
return G_SOURCE_REMOVE which results in the temporary GSource being
|
||||
destroyed. A g_autoptr() will then remove the last reference.
|
||||
|
||||
What was overlooked, is that a second thread can come along and
|
||||
while it can't enter virNetClientIOEventLoop, it will register an
|
||||
idle source that uses virNetClientIOWakeup to interrupt the
|
||||
original thread's 'g_main_loop_run' call. When this happens the
|
||||
virNetClientIOEventFD callback never runs, and so the temporary
|
||||
GSource is not destroyed. The g_autoptr() will remove a reference,
|
||||
but by virtue of still being attached to the event context, there
|
||||
is an extra reference held causing GSource to be leaked. The
|
||||
next time 'g_main_loop_run' is called, the original GSource will
|
||||
trigger its callback, and access data that was allocated on the
|
||||
stack by the previous thread, and likely SEGV.
|
||||
|
||||
To solve this, the thread calling 'g_main_loop_run' must call
|
||||
g_source_destroy, immediately upon return, to guarantee that
|
||||
the temporary GSource is removed.

Subject: [PATCH 2/3] virarptable: Fix check for message length
|
||||
Content-type: text/plain
|
||||
|
||||
The previous check was all wrong since it calculated the how long would
|
||||
the netlink message be if the netlink header was the payload and then
|
||||
subtracted that from the whole message length, a variable that was not
|
||||
used later in the code. This check can fail if there are no additional
|
||||
payloads, struct rtattr in particular, which we are parsing later,
|
||||
however the RTA_OK macro would've caught that anyway.

Subject: [PATCH] Avoid hidden cgroup mount points
|
||||
|
||||
Currently the scan of the /proc/mounts file used to find cgroup mount
|
||||
points doesn't take into account that mount points may hidden by other
|
||||
mount points. For, example in certain Kubernetes environments the
|
||||
/proc/mounts contains the following lines:
|
||||
|
||||
cgroup /sys/fs/cgroup/net_prio,net_cls cgroup ...
|
||||
tmpfs /sys/fs/cgroup tmpfs ...
|
||||
cgroup /sys/fs/cgroup/net_cls,net_prio cgroup ...
|
||||
|
||||
In this particular environment the first mount point is hidden by the
|
||||
second one. The correct mount point is the third one, but libvirt will
|
||||
never process it because it only checks the first mount point for each
|
||||
controller (net_cls in this case). So libvirt will try to use the first
|
||||
mount point, which doesn't actually exist, and the complete detection
|
||||
process will fail.
|
||||
|
||||
To avoid that issue this patch changes the virCgroupDetectMountsFromFile
|
||||
function so that when there are duplicates it takes the information from
|
||||
the last line in /proc/mounts. This requires removing the previous
|
||||
explicit condition to skip duplicates, and adding code to free the
|
||||
memory used by the processing of duplicated lines.

Subject: [PATCH 3/3] virarptable: End parsing earlier in case of NLMSG_DONE
|
||||
Content-type: text/plain
|
||||
|
||||
Check for the last multipart message right as the first thing. The
|
||||
presumption probably was that the last message might still contain a
|
||||
payload we want to parse. However that cannot be true since that would
|
||||
have to be a type RTM_NEWNEIGH. This was not caught because older
|
||||
kernels were note sending NLMSG_DONE and probably relied on the fact
|
||||
that the parsing just stops after all the messages are walked through,
|
||||
which the NLMSG_OK macro successfully did.

Subject: [PATCH] docs: schema: make disk driver name attribute optional
|
||||
|
||||
/domain/devices/disk/driver/@name is not a required or mandatory
|
||||
attribute according to formatdomain, and indeed it was agreed on
|
||||
IRC that the attribute is "optional for input, recommended (but
|
||||
not required) for output". Currently the schema requires the
|
||||
attribute, causing virt-xml-validate to fail on disk config where
|
||||
the driver name is not explicitly specified. E.g.
|
||||
|
||||
# cat test.xml | grep -A 5 cdrom
|
||||
<disk type='file' device='cdrom'>
|
||||
<driver type='raw'/>
|
||||
<target dev='hdb' bus='ide'/>
|
||||
<readonly/>
|
||||
<address type='drive' controller='0' bus='0' target='0' unit='1'/>
|
||||
</disk>
|
||||
|
||||
# virt-xml-validate test.xml
|
||||
Relax-NG validity error : Extra element devices in interleave
|
||||
test.xml:21: element devices: Relax-NG validity error : Element domain failed to validate content
|
||||
test.xml fails to validate
|
||||
|
||||
Relaxing the name attribute to be optional fixes the validation
|
||||
|
||||
# virt-xml-validate test.xml
|
||||
test.xml validates

Subject: [PATCH] qemu: virtiofs: set correct label when creating the socket

MIME-Version: 1.0

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

Content-Transfer-Encoding: 8bit

Use svirt_t instead of virtd_t, since virtd_t is not available in the
|
||||
session mode and qemu with svirt_t won't be able to talk to unconfined_t
|
||||
socket.
