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 2/8] wireshark: Switch header files to #pragma once
Content-type: text/plain
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 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).

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.

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].
