Due to too early RCT0 interrput, win10x32 may hang on booting. This problem can be reproduced by doing power cycle on win10x32 guest. In our environment, we have 10 win10x32 and stress power cycle. The problem will happen about 20 rounds. Below shows some log with comment: The normal case: 22831@1551928392.984687:e1000x_rx_disabled Received packet dropped because receive is disabled RCTL = 0 22831@1551928392.985655:e1000x_rx_disabled Received packet dropped because receive is disabled RCTL = 0 22831@1551928392.985801:e1000x_rx_disabled Received packet dropped because receive is disabled RCTL = 0 e1000: set_ics 0, ICR 0, IMR 0 e1000: set_ics 0, ICR 0, IMR 0 e1000: set_ics 0, ICR 0, IMR 0 e1000: RCTL: 0, mac_reg[RCTL] = 0x0 22831@1551928393.056710:e1000x_rx_disabled Received packet dropped because receive is disabled RCTL = 0 e1000: set_ics 0, ICR 0, IMR 0 e1000: ICR read: 0 e1000: set_ics 0, ICR 0, IMR 0 e1000: set_ics 0, ICR 0, IMR 0 e1000: RCTL: 0, mac_reg[RCTL] = 0x0 22831@1551928393.077548:e1000x_rx_disabled Received packet dropped because receive is disabled RCTL = 0 e1000: set_ics 0, ICR 0, IMR 0 e1000: ICR read: 0 e1000: set_ics 2, ICR 0, IMR 0 e1000: set_ics 2, ICR 2, IMR 0 e1000: RCTL: 0, mac_reg[RCTL] = 0x0 22831@1551928393.102974:e1000x_rx_disabled Received packet dropped because receive is disabled RCTL = 0 22831@1551928393.103267:e1000x_rx_disabled Received packet dropped because receive is disabled RCTL = 0 e1000: RCTL: 255, mac_reg[RCTL] = 0x40002 <- win10x32 says it can handle RX now e1000: set_ics 0, ICR 2, IMR 9d <- unmask interrupt e1000: RCTL: 255, mac_reg[RCTL] = 0x48002 e1000: set_ics 80, ICR 2, IMR 9d <- interrupt and work! ...

-net socket has a fd argument, and may be passed pre-opened sockets. TCP sockets use framing. UDP sockets have datagram boundaries. When given a unix dgram socket, it will be able to read from it, but will attempt to send on the dgram_dst, which is unset. The other end will not receive the data. Let's teach -net socket to recognize a UNIX DGRAM socket, and use the regular send() command (without dgram_dst). This makes running slirp out-of-process possible that way (python pseudo-code): a, b = socket.socketpair(socket.AF_UNIX, socket.SOCK_DGRAM) subprocess.Popen('qemu -net socket,fd=%d -net user' % a.fileno(), shell=True) subprocess.Popen('qemu ... -net nic -net socket,fd=%d' % b.fileno(), shell=True) Signed-off-by: NMarc-André Lureau <marcandre.lureau@redhat.com> Signed-off-by: NJason Wang <jasowang@redhat.com>

The Mesa library tries to set process affinity on some of its threads in order to optimize its performance. Currently this results in QEMU being immediately terminated when seccomp is enabled. Mesa doesn't consider failure of the process affinity settings to be fatal to its operation, but our seccomp policy gives it no choice in gracefully handling this denial. It is reasonable to consider that malicious code using the resource control syscalls to be a less serious attack than if they were trying to spawn processes or change UIDs and other such things. Generally speaking changing the resource control setting will "merely" affect quality of service of processes on the host. With this in mind, rather than kill the process, we can relax the policy for these syscalls to return the EPERM errno value. This allows callers to detect that QEMU does not want them to change resource allocations, and apply some reasonable fallback logic. The main downside to this is for code which uses these syscalls but does not check the return value, blindly assuming they will always succeeed. Returning an errno could result in sub-optimal behaviour. Arguably though such code is already broken & needs fixing regardless. Signed-off-by: NDaniel P.

The vCont packet accepts a series of actions, each being applied on a given thread ID. Giving no thread ID for an action is valid and means "all threads". This commit fixes vCont packets being incorrectly rejected when no thread ID was given for an action. In multiprocess mode, the GDB Remote Protocol specification is unclear on what "all threads" means. We choose to apply the action on all threads of all attached processes. This commit is based on the initial fix by Lucien Murray-Pitts.

由 Kevin Wolf 提交于
If qemu-img convert sees that the target image isn't zero-initialised yet, it tries to do an efficient zero write for the whole image first to save the overhead of repeated explicit zero writes during the conversion. Obviously, this provides only an advantage if the pre-zeroing is actually efficient. Otherwise, we can end up writing zeroes slowly while zeroing out the whole image, and then overwrite the same blocks again with real data, potentially doubling the written data. Pass BDRV_REQ_NO_FALLBACK to blk_make_zero() to avoid this case. If we can't efficiently zero out, we'll instead write explicit zeroes only if there is no data to be written to a block.

We know that the kernel implements a slow fallback code path for BLKZEROOUT, so if BDRV_REQ_NO_FALLBACK is given, we shouldn't call it. The other operations we call in the context of .bdrv_co_pwrite_zeroes should usually be quick, so no modification should be needed for them. If we ever notice that there are additional problematic cases, we can still make these conditional as well. Signed-off-by: NKevin Wolf <kwolf@redhat.com> Acked-by: NEric Blake <eblake@redhat.com>

We reject undersized backends with a rather enigmatic "failed to read the initial flash content" error. For instance: $ qemu-system-ppc64 -S -display none -M sam460ex -drive if=pflash,format=raw,file=eins.img qemu-system-ppc64: Initialization of device cfi.pflash02 failed: failed to read the initial flash content We happily accept oversized images, ignoring their tail. Throwing away parts of firmware that way is pretty much certain to end in an even more enigmatic failure to boot. Require the backend's size to match the device's size exactly. Report mismatch like this: qemu-system-ppc64: Initialization of device cfi.pflash01 failed: device requires 1048576 bytes, block backend provides 512 bytes Improve the error for actual read failures to "can't read block backend". To avoid duplicating even more code between the two pflash device models, do all that in new helper blk_check_size_and_read_all(). The error reporting can still be confusing. For instance: qemu-system-ppc64 -S -display none -M taihu -drive if=pflash,format=raw,file=eins.img -drive if=pflash,unit=1,format=raw,file=zwei.img qemu-system-ppc64: Initialization of device cfi.pflash02 failed: device requires 2097152 bytes, block backend provides 512 bytes Leaves the user guessing which of the two -drive is wrong.

There are no harm but just looks weird to return bool in pointer-returning function. Introduced in 69240fe6 with the whole failure-checking "if" chunk.

The assert checking if the value of lexer->state in next_state(), which is used as an index to the 'json_lexer' array, incorrectly checks for an index value less than or equal to ARRAY_SIZE(json_lexer). Fix assert so that it just checks for an index less than the array size.

This NULL check was required while introduced in 680d16dc. Later refactor added a NULL check in error_setv(), so this check is now redundant. Reviewed-by: NDaniel P.

The recently added max-postcopy-bandwidth parameter is only read at the transition from precopy->postcopy where as the older max-bandwidth parameter updates the migration bandwidth when changed even if the migration is already running. Fix this discrepency so that: a) You can change the bandwidth during postcopy by setting max-postcopy-bandwidth b) Changing max-bandwidth during postcopy has no effect (it currently changes the postcopy bandwidth which isn't expected).

In this patch we add the processing state for COLOExitReason, because we have to identify COLO in the failover processing state or failover error state. In the way, we can handle all the failover state. We have improved the description of the COLOExitReason by the way.
