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.

WIRESHARK_VERSION macro definition among with its deps into

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].

|

When the session dies or when the system is going to be shut down
|
||||
we save all active VMs and exit libvirtd.
|
||||
|
||||
Additionally whenever there is an active domain we hold a
|
||||
shutdown inhibitor to avoid shutting down before all the
|
||||
VMs are saved.
