Network transport abstraction layer supports packet fragmentation. While fragmenting a packet, it checks for more fragments from packet length and current fragment length. It is susceptible to an infinite loop, if the current fragment length is zero. Add check to avoid it.

Since aa5cb7f5, the chardevs are being cleaned up when leaving qemu, before the atexit() handlers. audio_cleanup() may use the monitor to notify of changes. For compatibility reasons, let's clean up audio before the monitor so it keeps emitting monitor events. The audio_atexit() function is made idempotent (so it can be called multiple times), and renamed to audio_cleanup(). Since coreaudio backend is using a 'isAtexit' code path, change it to check audio_is_cleaning_up() instead, so the path is taken during normal exit.

109 iotest is broken for raw after 0965a41e [mirror: double performance of the bulk stage if the disc is full] The problem is with finishing block-job with error: before specified patch mirror was not very async and it created one big request at disk start, this request finished with error and qemu produced BLOCK_JOB_COMPLETED with zero progress. After 0965a41e, mirror starts several smaller requests in parallel, when BLOCK_JOB_COMPLETED emited we have some successful non-zero progress. This patch solves the issue by filtering out progress from 109 test output. Signed-off-by: NVladimir Sementsov-Ogievskiy <vsementsov@virtuozzo.com> Signed-off-by: NKevin Wolf <kwolf@redhat.com>

When a TCE table (sPAPR IOMMU context) is in disabled state (which is true by default for the 64-bit window), it has tcet->nb_table == 0 and tcet->table == NULL. However, on system reset, spapr_tce_reset() executes, which unconditionally calls memset(tcet->table, 0, table_size); We get away with this in practice, because it's a zero length memset(), but memset() on a NULL pointer is undefined behaviour, so we should not call it in this case.

Prior to c8721d35 "spapr: Error out when CPU hotplug is attempted on older pseries machines", attempting to use query-hotpluggable-cpus on pseries-2.6 and earlier machine types would SEGV. That change fixed that, but due to some unexpected interactions in init order and a brown-paper-bag worthy failure to test, it accidentally disabled query-hotpluggable-cpus for all pseries machine types, including the current one which should allow it. In fact, query_hotpluggable_cpus needs to be non-NULL when and only when the dr_cpu_enabled flag in sPAPRMachineClass is set, which makes dr_cpu_enabled itself redundant. This patch removes dr_cpu_enabled, instead directly setting query_hotpluggable_cpus from the machine class_init functions, and using that to determine the availability of CPU hotplug when necessary.

Move the sglist destruction inside of ncq_err and then delete it from the other two locations to keep it tidy. Call dma_buf_commit in ide_dma_cb after the early return. Though, this is also a little wonky because this routine does more than clear the list, but it is at the moment the centralized "we're done with the sglist" function and none of the other side effects that occur in dma_buf_commit will interfere with the reset that occurs from ide_restart_bh, I think Signed-off-by: NMarc-André Lureau <marcandre.lureau@redhat.com> Reviewed-by: NJohn Snow <jsnow@redhat.com>

Make sure the connection data got freed when closing the chardev, to avoid leaks. Introduce tcp_chr_free_connection() to clean all connection related data, and move some tcp_chr_close() clean-ups there. (while at it, set write_msgfds_num to 0 when clearing array in tcp_set_msgfds()) Signed-off-by: NMarc-André Lureau <marcandre.lureau@redhat.com> Reviewed-by: NPaolo Bonzini <pbonzini@redhat.com>

Rather than rely on recursion during the middle of register allocation, lower indirect registers to loads and stores off the indirect base into plain temps. For an x86_64 host, with sufficient registers, this results in identical code, modulo the actual register assignments. For an i686 host, with insufficient registers, this means that temps can be (temporarily) spilled to the stack in order to satisfy an allocation. This as opposed to the possibility of not being able to spill, to allocate a register for the indirect base, in order to perform a spill.

We only need two bits per temporary. Fold the two bytes into one, and reduce the memory and cachelines required during compilation. Reviewed-by: NAurelien Jarno <aurelien@aurel32.net> Signed-off-by: NRichard Henderson <rth@twiddle.net>
