Block I/O throttling uses timers and currently always adds them to the main loop. Throttling will break if bdrv_set_aio_context() is used to move a BlockDriverState to a different AioContext. This patch adds throttle_detach/attach_aio_context() interfaces so the throttling timers and uses them to move timers to the new AioContext. Note that bdrv_set_aio_context() already drains all requests so we're sure no throttled requests are pending. The test cases need to be updated since the throttle_init() interface has changed.

2014-05-28aio: Fix use-after-free in cancellation pathFam Zheng
The current flow of canceling a thread from THREAD_ACTIVE state is: 1) Caller wants to cancel a request, so it calls thread_pool_cancel. 2) thread_pool_cancel waits on the conditional variable elem->check_cancel. 3) The worker thread changes state to THREAD_DONE once the task is done, and notifies elem->check_cancel to allow thread_pool_cancel to continue execution, and signals the notifier (pool->notifier) to allow callback function to be called later. But because of the global mutex, the notifier won't get processed until step 4) and 5) are done. 4) thread_pool_cancel continues, leaving the notifier signaled, it just returns to caller. 5) Caller thinks the request is already canceled successfully, so it releases any related data, such as freeing elem->common.opaque. 6) In the next main loop iteration, the notifier handler, event_notifier_ready, is called. It finds the canceled thread in THREAD_DONE state, so calls elem->common.cb, with an (likely) dangling opaque pointer. This is a use-after-free. Fix it by calling event_notifier_ready before leaving thread_pool_cancel. Test case update: This change will let cancel complete earlier than test-thread-pool.c expects, so update the code to check this case: if it's already done, done_cb sets .aiocb to NULL, skip calling bdrv_aio_cancel on them.

A huge image size could cause s->l1_size to overflow. Make sure that images never require a L1 table larger than what fits in s->l1_size.

2014-05-19qcow1: Validate L2 table size (CVE-2014-0222)Kevin Wolf
Too large L2 table sizes cause unbounded allocations. Images actually created by qemu-img only have 512 byte or 4k L2 tables. To keep things consistent with cluster sizes, allow ranges between 512 bytes and 64k (in fact, down to 1 entry = 8 bytes is technically working, but L2 table sizes smaller than a cluster don't make a lot of sense). This also means that the number of bytes on the virtual disk that are described by the same L2 table is limited to at most 8k * 64k or 2^29, preventively avoiding any integer overflows.

2014-05-15qapi: Replace uncommon use of the error API by the common oneMarkus Armbruster
We commonly use the error API like this: err = NULL; foo(..., &err); if (err) { goto out; } bar(..., &err); Every error source is checked separately. The second function is only called when the first one succeeds. Both functions are free to pass their argument to error_set(). Because error_set() asserts no error has been set, this effectively means they must not be called with an error set. The qapi-generated code uses the error API differently: // *errp was initialized to NULL somewhere up the call chain frob(..., errp); gnat(..., errp); Errors accumulate in *errp: first error wins, subsequent errors get dropped. To make this work, the second function does nothing when called with an error set. Requires non-null errp, or else the second function can't see the first one fail. This usage has also bled into visitor tests, and two device model object property getters rtc_get_date() and balloon_stats_get_all(). With the "accumulate" technique, you need fewer error checks in callers, and buy that with an error check in every callee. Can be nice. However, mixing the two techniques is confusing. You can't use the "accumulate" technique with functions designed for the "check separately" technique. You can use the "check separately" technique with functions designed for the "accumulate" technique, but then error_set() can't catch you setting an error more than once. Standardize on the "check separately" technique for now, because it's overwhelmingly prevalent.

2014-05-15Revert "iotests: Use configured python"Peter Maydell
This reverts commit f915db07ef9c368ea6db6430256de064fdd1525f. This commit is broken because it does not account for the build tree and the source tree being different, and can cause build failures for out-of-tree builds. Revert it until we can identify a better solution to the problem.

2014-05-14savevm: Remove all the unneeded version_minimum_id_old (rest)Juan Quintela
After previous Peter patch, they are redundant. This way we don't assign them except when needed. Once there, there were lots of case where the ".fields" indentation was wrong: .fields = (VMStateField []) { and .fields = (VMStateField []) { Change all the combinations to: .fields = (VMStateField[]){ The biggest problem (appart from aesthetics) was that checkpatch complained when we copy&pasted the code from one place to another.

2014-05-09block: qemu-iotests - test for live migrationJeff Cody
This is an initial, simple live migration test from one running VM to another, using monitor commands. This is also an example of using the new common.qemu functions for controlling multiple running qemu instances, for tests that need a live qemu vm.

2014-05-09block: qemu-iotests - update 085 to use common.qemuJeff Cody
The new functionality of common.qemu implements the QEMU control and communication functionality that was originally in test 085. This removes that now-duplicate functionality, and uses the common.qemu functions. The QEMU commandline changes slightly due to this; in addition to monitor and qmp i/o options, the new QEMU commandline from inside common.qemu now introduces -machine accel=qtest.

2014-05-09block: qemu-iotests - add common.qemu, for bash-controlled qemu testsJeff Cody
This creates some common functions for bash language qemu-iotests to control, and communicate with, a running QEMU process. 4 functions are introduced: 1. _launch_qemu() This launches the QEMU process(es), and sets up the file descriptors and fifos for communication. You can choose to launch each QEMU process listening for either QMP or HMP monitor. You can call this function multiple times, and save the handle returned from each. The returned handle is in $QEMU_HANDLE. You must copy this value. Commands 2 and 3 use the handle received from _launch_qemu(), to talk to the appropriate process. 2. _send_qemu_cmd() Sends a command string, specified by $2, to QEMU. If $3 is non-NULL, _send_qemu_cmd() will wait to receive $3 as a required result string from QEMU. Failure to receive $3 will cause the test to fail. The command can optionally be retried $qemu_cmd_repeat number of times. Set $qemu_error_no_exit to not force the test the fail on exit; in this case, $QEMU_STATUS[$1] will be set to -1 on failure. 3. _timed_wait_for() Waits for a response, for up to a default of 10 seconds. If $2 is not seen in that time (anywhere in the response), then the test fails. Primarily used by _send_qemu_cmd, but could be useful standalone, as well. To prevent automatic exit (and therefore test failure), set $qemu_error_no_exit to a non-NULL value. If $silent is a non-NULL value, then output to stdout will be suppressed. 4. _cleanup_qemu() Kills the running QEMU processes, and removes the fifos.
