Subject: [PATCH] Fix off-by-one error in udevListInterfacesByStatus

Ever since this function was introduced in 2012 it could've tried
|
||||
filling in an extra interface name. That was made worse in 2019 when
|
||||
the caller functions started accepting NULL arrays of size 0.
|
||||
|
||||
This is assigned CVE-2024-1441.

Subject: [PATCH] interface: fix udev_device_get_sysattr_value return value
|
||||
check
|
||||
|
||||
Reviewing the code I found that return value of function
|
||||
udev_device_get_sysattr_value() is dereferenced without a check.
|
||||
udev_device_get_sysattr_value() may return NULL by number of reasons.
|
||||
|
||||
v2: VIR_DEBUG added, replaced STREQ(NULLSTR()) with STREQ_NULLABLE()
|
||||
v3: More checks added, to skip earlier. More verbose VIR_DEBUG.

Subject: [PATCH] rpc: fix race in waking up client event loop
|
||||
MIME-Version: 1.0
|
||||
Content-Type: text/plain; charset=UTF-8
|
||||
Content-Transfer-Encoding: 8bit
|
||||
|
||||
The first thread to issue a client RPC request will own the event
|
||||
loop execution, sitting in the virNetClientIOEventLoop function.
|
||||
|
||||
It releases the client lock while running:
|
||||
|
||||
virNetClientUnlock()
|
||||
g_main_loop_run()
|
||||
virNetClientLock()
|
||||
|
||||
If a second thread arrives with an RPC request, it will queue it
|
||||
for the first thread to process. To inform the first thread that
|
||||
there's a new request it calls g_main_loop_quit() to break it out
|
||||
of the main loop.
|
||||
|
||||
This works if the first thread is in g_main_loop_run() at that
|
||||
time. There is a small window of opportunity, however, where
|
||||
the first thread has released the client lock, but not yet got
|
||||
into g_main_loop_run(). If that happens, the wakeup from the
|
||||
second thread is lost.
|
||||
|
||||
This patch deals with that by changing the way the wakeup is
|
||||
performed. Instead of directly calling g_main_loop_quit(), the
|
||||
second thread creates an idle source to run the quit function
|
||||
from within the first thread. This guarantees that the first
|
||||
thread will see the wakeup.

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.

|
||||
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] conf: Restore setting default bus for input devices
|
||||
|
||||
Prior to v9.3.0-rc1~30 we used to set default bus for <input/>
|
||||
devices, during XML parsing. In the commit this code was moved to
|
||||
a post parse callback. But somehow the line that sets the bus in
|
||||
one specific case disappeared. Bring it back.
|
||||
|
||||
Resolves: https://gitlab.com/libvirt/libvirt/-/issues/577
|
||||
Fixes: c4bc4d3b82fbe22e03c986ca896090f481df5c10
