block: New BdrvChildRole.activate() for blk_resume_after_migration()
Instead of manually calling blk_resume_after_migration() in migration
code after doing bdrv_invalidate_cache_all(), integrate the BlockBackend
activation with cache invalidation into a single function. This is
achieved with a new callback in BdrvChildRole that is called by
bdrv_invalidate_cache_all().

migration: Unify block node activation error handling
Migration code activates all block driver nodes on the destination when
the migration completes. It does so by calling
bdrv_invalidate_cache_all() and blk_resume_after_migration(). There is
one code path for precopy and one for postcopy migration, resulting in
four function calls, which used to have three different failure modes.
This patch unifies the behaviour so that failure to activate all block
nodes is non-fatal, but the error message is logged and the VM isn't
automatically started. 'cont' will retry activating the block nodes.

test-qga: Actually test 0xff sync bytes
Commit
62c39b3 introduced test-qga, and at face value, appears
to be testing the 'guest-sync' behavior that is recommended for
guests in sending 0xff to QGA to force the parser to reset. But
this aspect of the test has never actually done anything: the
qmp_fd() call chain converts its string argument into QObject,
then converts that QObject back to the actual string that is
sent over the wire - and the conversion process silently drops
the 0xff byte from the string sent to QGA, thus never resetting
the QGA parser.
An upcoming patch will get rid of the wasteful round trip
through QObject, at which point the string in test-qga will be
directly sent over the wire.
But fixing qmp_fd() to actually send 0xff over the wire is not
all we have to do - the actual QMP parser loudly complains that
0xff is not valid JSON, and sends an error message _prior_ to
actually parsing the 'guest-sync' or 'guest-sync-delimited'
command. With 'guest-sync', we cannot easily tell if this error
message is a result of our command - which is WHY we invented
the 'guest-sync-delimited' command. So for the testsuite, fix
things to only check 0xff behavior on 'guest-sync-delimited',
and to loop until we've consumed all garbage prior to the
requested delimiter, which is compatible with the documented actions
that a real QGA client is supposed to do.
Ideally, we'd fix the QGA JSON parser to silently ignore 0xff
rather than sending an error message back, at which point we
could enhance this test for 'guest-sync' as well as for

is NULL on success and that QDECREF(NULL) is safe. So merge the

hax: Fix memory mapping de-duplication logic
hax_update_mapping() avoids unnecessary and potentially expensive
calls to HAX_VM_IOCTL_SET_RAM by computing the net result (i.e.
effective mapping changes) of each MemoryRegion transaction, with
the help of a linked list of HAXMapping objects.
However, when processing a new mapping that overlaps with an
existing mapping in the list, it fails to handle the case where the
start address of the new mapping is above that of the existing
mapping in the guest physical address space. This happens when QEMU
is launched with "-machine q35 -enable-hax", which involves the
following MemoryRegion transaction for digging the VGA hole:
region_del: 0x00000000->0x08000000 VA
05fa0000 ('pc.ram')
region_add: 0x00000000->0x000a0000 VA
05fa0000 ('pc.ram')
region_add: 0x000a0000->0x000c0000 VA
00000000 ('vga-lowmem')
region_add: 0x000c0000->0x08000000 VA
06060000 ('pc.ram')
where the third MemoryRegion is MMIO and is ignored. The current
de-duplication logic handles the last MemoryRegion incorrectly and
produces the following result:
hax_mapping_dump_list updates:
+ 0x000c0000->0x08000000 VA 0x06060000
- 0x07fe0000->0x08000000 VA 0x0df80000
which is why VGA emulation does not work for Q35.
With this patch, one can see VGA output as Q35 boots up. Note that
Q35 support also requires a change to HAXM kernel module, which is
not available in the current HAXM release (6.1.2).
+ Add a warning if the input MemoryRegion is a ROM device, which is
not supported by HAXM kernel module at this time.

checkpatch: Disallow glib asserts in main code
Glib commit
a6a875068779 (from 2013) made many of the glib assert

This causes two problems:
a) Compilers moan that your code is unsafe even though you've
put an assert in before the point of use.
b) Someone evil could, in a library, call
g_test_set_nonfatal_assertions() and cause our assertions in
important places not to fail and potentially allow memory overruns.
Ban most of the glib assertion functions (basically everything except
g_assert and g_assert_not_reached) except in tests/

trace: add qemu mutex lock and unlock trace events
These trace events were very useful to help me to understand and find a
reordering issue in vfio, for example:
qemu_mutex_lock locked mutex 0x10905ad8
vfio_region_write (0001:03:00.0:region1+0xc0, 0x2020c, 4)
qemu_mutex_unlock unlocked mutex 0x10905ad8
qemu_mutex_lock locked mutex 0x10905ad8
vfio_region_write (0001:03:00.0:region1+0xc4, 0xa0000, 4)
qemu_mutex_unlock unlocked mutex 0x10905ad8
that also helped me to see the desired result after the fix:
qemu_mutex_lock locked mutex 0x10905ad8
vfio_region_write (0001:03:00.0:region1+0xc0, 0x2000c, 4)
vfio_region_write (0001:03:00.0:region1+0xc4, 0xb0000, 4)
qemu_mutex_unlock unlocked mutex 0x10905ad8
So it could be a good idea to have these traces implemented. It's worth
mentioning that they should be surgically enabled during the debugging,
otherwise it can flood the trace logs with lock/unlock messages.
How to use it:
trace-event qemu_mutex_lock on|off
trace-event qemu_mutex_unlock on|off
or
trace-event qemu_mutex* on|off
