Commit 7d0f982b changed generated introspection output to no longer
produce long lines in the generated .c file, but failed to adjust
comments to match. Add some clarity that the shorter length that
matters most is the overall QMP response on the wire.
Commit 25b1ef31 triggers a pep8 formatting nit.

The generated qapi_event_send_FOO() take an Error ** argument. They
can't actually fail, because all they do with the argument is passing it
to functions that can't fail: the QObject output visitor, and the
@qmp_emit callback, which is either monitor_qapi_event_queue() or
event_test_emit().
Drop the argument, and pass &error_abort to the QObject output visitor
and @qmp_emit instead.

PACK fails on the test from the Principles of Operation: F1F2F3F4
becomes 0000234C instead of 0001234C due to an off-by-one error.
Furthermore, it overwrites one extra byte to the left of F1.
If len_dest is 0, then we only want to flip the 1st byte and never loop
over the rest. Therefore, the loop condition should be > and not >=.
If len_src is 1, then we should flip the 1st byte and pack the 2nd.
Since len_src is already decremented before the loop, the first
condition should be >=, and not >.
Likewise for len_src == 2 and the second condition.

CSST is defined as:

It means that the first parameter is handled by in1_la1().
in1_la1() fills addr1 field, and not in1.
Furthermore, when extract32() is used for the alignment check, the
third parameter should specify the number of trailing bits that must
be 0. For FC these numbers are:
FC=0 (word, 4 bytes): 2
FC=1 (double word, 8 bytes): 3
FC=2 (quad word, 16 bytes): 4
For SC these numbers correspond to the size:

Commit 2c88b098e7 added a call to SPAPR_MACHINE_GET_CLASS(spapr) in
spapr_phb_realize() before we check spapr isn't NULL. This causes QEMU
to crash when starting a non-pseries machine with a sPAPR PHB.
This could be fixed by setting the smc variable after the null check,
but it seems more explicit to use a ternary operator to skip the call
to SPAPR_MACHINE_GET_CLASS() if spapr is NULL, since spapr_phb_realize()
will return immediately in this case.
This was reported by Coverity (CID 1395170 and 1395183).

[ kraxel: buildfix: util/drm.o must be CONFIG_OPENGL not CONFIG_LINUX ]
Signed-off-by: Gerd Hoffmann <kraxel@redhat.com>
There are many error_report()s that can be used in frequently called
functions, especially on IO paths. That can be unideal in that
malicious guest can try to trigger the error tons of time which might
use up the log space on the host (e.g., libvirt can capture the stderr
of QEMU and put it persistently onto disk). In VT-d emulation code, we
have trace_vtd_error() tracer. AFAIU all those places can be replaced
by something like error_report() but trace points are mostly used to
avoid the DDOS attack that mentioned above. However using trace points
mean that errors are not dumped if trace not enabled.
It's not a big deal in most modern server managements since we have
things like logrotate to maintain the logs and make sure the quota is
expected. However it'll still be nice that we just provide another way
to restrict message generations. In most cases, this kind of
error_report()s will only provide valid information on the first message
sent, and all the rest of similar messages will be mostly talking about
the same thing. This patch introduces *_report_once() helpers to allow
a message to be dumped only once during one QEMU process's life cycle.
It will make sure: (1) it's on by deffault, so we can even get something
without turning the trace on and reproducing, and (2) it won't be
affected by DDOS attack.
To implement it, I stole the printk_once() macro from Linux.
