All these errors are caused by a buggy guest: QEMU should not exit. With this patch, if virtio_blk_handle_request() detects a buggy request, it marks the device as broken and returns an error to the caller so it takes appropriate action. In the case of virtio_blk_handle_vq(), we detach the request from the virtqueue, free its allocated memory and stop popping new requests. We don't need to bother about multireq since virtio_blk_handle_request() errors out early and mrb.num_reqs == 0. In the case of virtio_blk_dma_restart_bh(), we need to detach and free all queued requests as well.

A broken guest may send a request without providing buffers for the reply or for the request itself, and virtqueue_pop() will return an element with either in_num == 0 or out_num == 0. All 9P requests are expected to start with the following 7-byte header: uint32_t size_le; uint8_t id; uint16_t tag_le; If iov_to_buf() fails to return these 7 bytes, then something is wrong in the guest. In both cases, it is wrong to crash QEMU, since the root cause lies in the guest. This patch hence does the following: - keep the check of in_num since pdu_complete() assumes it has enough space to store the reply and we will send something broken to the guest - let iov_to_buf() handle out_num == 0, since it will return 0 just like if the guest had provided an zero-sized buffer. - call virtio_error() to inform the guest that the device is now broken, instead of aborting - detach the request from the virtqueue and free it Signed-off-by: NGreg Kurz <groug@kaod.org> Reviewed-by: NStefan Hajnoczi <stefanha@redhat.com> Reviewed-by: NMichael S.

Ports enter a "throttled" state when writing to the chardev would block. The current output VirtQueueElement is kept around until the chardev becomes writable again. There are several places in the virtio-serial lifecycle where the VirtQueueElement should be thrown away. For example, if the virtio device is reset then virtqueue elements are no longer valid. This patch adds the discard_throttle_data() function to unmap the scatter-gather list and decrement vq->inuse. This ensures that the VirtQueueElement is freed properly.

During device reset or similar situations a VirtQueueElement needs to be freed without pushing it onto the used ring or rewinding the virtqueue. Extract a new function to do this. Later patches add virtio_detach_element() calls to existing device so that scatter-gather lists are unmapped and vq->inuse goes back to zero during device reset. Currently some devices don't bother and simply call g_free(elem) which is not a clean way to throw away a VirtQueueElement.

Add support for enabling the virtio 1.0 "emergency write" (VIRTIO_CONSOLE_F_EMERG_WRITE) feature. The previous patch introduced the plumbing required for this; now we expose the virtio feature to the guest. The feature is disabled for compatibility machines to avoid exposing a new feature to existing guests. As required by the virtio 1.0 spec, the emergency write functionality is available to the guest even if the guest doesn't negotatiate the feature, as well as before feature negotation.

The quiet-command make rule currently takes two arguments: the command and arguments to run, and a string to print if the V flag is not set (ie we are not being verbose). By convention, the string printed is of the form " NAME some args". Unfortunately to get nicely lined up output all the strings have to agree about what column the arguments should start in, which means that if we add a new quiet-command usage which wants a slightly longer CMD name then we either put up with misalignment or change every quiet-command string. Split the quiet-mode string into two, the "NAME" and the "same args" part, and use printf(1) to format the string automatically. This means we only need to change one place if we want to support a longer maximum name. In particular, we can now print 7-character names lined up properly (they are needed for the OSX "SETTOOL" invocation). Change all the uses of quiet-command to the new syntax. (Any which are missed or inadvertently reintroduced via later merges will result in slightly misformatted quiet output rather than disaster.) A few places in the pc-bios/ makefiles are updated to use "BUILD", "SIGN" and "STRIP" rather than "Building", "Signing" and "Stripping" for consistency and to keep them below 7 characters. Module .mo links now print "LD" rather than the nonstandard "LD -r".

A couple of distributors are compiling their distributions with "-mcpu=power8" for ppc64le these days, so the user sooner or later runs into a crash there when not explicitely specifying the "-cpu POWER8" option to QEMU (which is currently using POWER7 for the "pseries" machine by default). Due to this reason, the linux-user target already switched to POWER8 a while ago (see commit de3f1b98). Since the softmmu target of course has the same problem, we should switch there to POWER8 for the newer machine types, too.

SLOF is unfortunately quite slow when running with TCG, so the pxe test is also performing rather slow here. By using "-nodefaults" we can disable some devices (vscsi) that we are not interested in here, so that SLOF does not have to scan them during boot and thus starts up a little bit faster. The ppc64 pxe-test now only takes 27 seconds on my laptop instead of 33 seconds. The "-nodefaults" flag seems to work fine for the x86 tests, too, so it is added here unconditionally here (though there is no speed-up on x86 by using this flag).

If the user passes an alias name and a property to -cpu, QEMU fails to find the CPU definition and exits. $ qemu-system-ppc64 -cpu POWER8E,compat=power7 qemu-system-ppc64: Unable to find sPAPR CPU Core definition This happens because spapr_get_cpu_core_type() passes the full string from the command line (i.e. "POWER8E,compat=power7") to ppc_cpu_lookup_alias(), instead of the alias name piece only (i.e. "POWER8E"). The fix is to pass model_pieces[0] to ppc_cpu_lookup_alias().
