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.

The udevInterfaceGetXMLDesc method takes a reference on the udev

driver as its first action. If the virCheckFlags() condition

fails, however, this reference is never released.

udev_device_get_sysattr_value() may return NULL by number of reasons.

Subject: [PATCH] rpc: avoid leak of GSource in use for interrupting main loop

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.

|
||||
|
||||
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.

The genxdrstub.pl script generates some header files. But they
|

use the old pattern to guard against multiple inclusion:

|

#ifndef SOMETHING_H
|

#define SOMETHING_H

...

#endif

Change the script to generate just '#pragma once' used everywhere

else in our code.

Subject: [PATCH 4/8] wireshark: Fix int type of some virNetMessageHeader
|
||||
members
|
||||
Content-type: text/plain
|
||||
|
||||
Our virNetMessageHeader is a struct that's declared as follows:
|
||||
|
||||
struct virNetMessageHeader {
|
||||
unsigned prog;
|
||||
unsigned vers;
|
||||
int proc;
|
||||
virNetMessageType type;
|
||||
unsigned serial;
|
||||
virNetMessageStatus status;
|
||||
};
|
||||
|
||||
Now, per RFC 4506 enums are also encoded as signed integers. This
|
||||
means, that only 'prog', 'vers' and 'serial' are really unsigned
|
||||
integers. The others ('proc', 'type' and 'status') are encoded as
|
||||
signed integers. Fix their type when dissecting.
|
||||
|
||||
While at it, also follow latest trend in wireshark and switch
|
||||
from guint32 to uint32_t.

Subject: [PATCH 5/8] wireshark: Don't special case retval of
|
||||
get_program_data() in dissect_libvirt_message()
|
||||
Content-type: text/plain
|
||||
|
||||
The get_program_data() function returns a pointer (in this
|
||||
specific case to an array of procedure strings) which, if
|
||||
non-NULL is then passed val_to_str(). Well, if val_to_str() sees
|
||||
NULL it is treated gracefully, i.e. like if the numeric value
|
||||
'proc' wasn't found in the array.
|
||||
|
||||
Therefore, there's no need to special case call to
|
||||
col_append_fstr(). Both result into the same behaviour.

Subject: [PATCH 6/8] wireshark: Introduce and use vir_val_to_str()
|
||||
Content-type: text/plain
|
||||
|
||||
Wireshark offers val_to_str() function which converts numeric
|
||||
value to string by looking up value ('val') in an array ('vs') of
|
||||
<val, string> pairs. If no corresponding string is found, then
|
||||
the value is formatted using given 'fmt' string.
|
||||
|
||||
Starting from wireshark-4.6.0 not only this function gained
|
||||
another argument but also returns a strdup()-ed string. To keep
|
||||
our code simple, let's introduce a wrapper so which can be then
|
||||
adjusted as needed.

Subject: [PATCH 7/8] wireshark: Don't leak column strings
|
||||
Content-type: text/plain
|
||||
|
||||
One of the problems of using val_to_str() is that it may return a
|
||||
const string from given table ('vs'), OR return an allocated one.
|
||||
Since the caller has no idea which case it is, it resides to safe
|
||||
option and don't free returned string. But that might lead to a
|
||||
memleak. This behaviour is fixed with wireshark-4.6.0 and support
|
||||
for it will be introduced soon. But first, make vir_val_to_str()
|
||||
behave like fixed val_to_str() from newer wireshark: just always
|
||||
allocate the string.
|
||||
|
||||
Now, if val_to_str() needs to allocate new memory it obtains
|
||||
allocator by calling wmem_packet_scope() which is what we may do
|
||||
too.
|
||||
|
||||
Hand in hand with that, we need to free the memory using the
|
||||
correct allocator, hence wmem_free(). But let's put it into a
|
||||
wrapper vir_wmem_free() because just like val_to_str(), it'll
|
||||
need additional argument when adapting to new wireshark.
|
||||
|
||||
Oh, and freeing the memory right after col_add_fstr() is safe as
|
||||
it uses vsnprintf() under the hood to format passed args.
|
||||
|
||||
One last thing, the wmem.h file used to live under epan/wmem/ but
|
||||
then in v3.5.0~240 [1] was moved to wsutil/wmem/.

Subject: [PATCH 8/8] wireshark: Adapt to wireshark-4.6.0
|
||||
Content-type: text/plain
|
||||
|
||||
The main difference is that wmem_packet_scope() is gone [1] but
|
||||
the packet_info struct has 'pool` member which points to the
|
||||
allocator used for given packet.
|
||||
|
||||
Unfortunately, while we were given pointer to packet_info at the
|
||||
entry level to our dissector (dissect_libvirt() ->
|
||||
tcp_dissect_pdus() -> dissect_libvirt_message()) it was never
|
||||
propagated to generated/primitive dissectors.
|
||||
|
||||
But not all dissectors need to allocate memory, so mark the new
|
||||
argument as unused. And while our generator could be rewritten so
|
||||
that the argument is annotated as unused iff it's really unused,
|
||||
I couldn't bother rewriting it. It's generated code after all.
|
||||
Too much work for little gain.
|
||||
|
||||
Another significant change is that val_to_str() now requires new
|
||||
argument: pointer to allocator to use because it always allocates
|
||||
new memory [2][3].

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
