Subject: [PATCH] interface: fix udev reference leak with invalid flags

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.

Subject: [PATCH] qemu, xen: add missing deps on virtlockd/virtlogd sockets
|
||||
MIME-Version: 1.0
|
||||
Content-Type: text/plain; charset=UTF-8
|
||||
Content-Transfer-Encoding: 8bit
|
||||
|
||||
The QEMU driver uses both virtlogd and virtlockd, while the Xen driver
|
||||
uses virtlockd. The libvirtd.service unit contains deps on the socket
|
||||
units for these services, but these deps were missed in the modular
|
||||
daemons. As a result the virtlockd/virtlogd sockets are not started
|
||||
when the virtqemud/virtxend daemons are started.

Subject: [PATCH] rpc: avoid leak of GSource in use for interrupting main loop
|
||||
MIME-Version: 1.0
|
||||
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.

|
||||
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 1/2] wireshark: Switch to tvb_bytes_to_str()
|
||||
|
||||
When the dissector sees a byte sequence that is either an opaque
|
||||
data (xdr_opaque) or a byte sequence (xdr_bytes) it formats the
|
||||
bytes as a hex numbers using our own implementation. But
|
||||
wireshark already provides a function for it: tvb_bytes_to_str().
|
||||
NB, the reason why it returns a const string is so that callers
|
||||
don't try to free it - the string is allocated using an allocator
|
||||
which will decide when to free it.
|
||||
|
||||
The wireshark formatter was introduced in wireshark commit of
|
||||
v1.99.2~479 and thus is present in the version we require at
|
||||
least (2.6.0).

|
||||
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 2/2] wireshark: Drop needless comment in dissect_xdr_bytes()
|
||||
|
||||
In the dissect_xdr_bytes() there's a comment that the string
|
||||
allocated by xdr_bytes() can't be freed using xdr_free(). Well,
|
||||
that is expected because xdr_bytes() used plain calloc() AND the
|
||||
string is not an XDR struct but plain 'char *' type. Passing it
|
||||
to xdr_free() must result in weird things happening.
