2018-03-26qcow2: Reset free_cluster_index when allocating a new refcount blockAlberto Garcia
When we try to allocate new clusters we first look for available ones starting from s->free_cluster_index and once we find them we increase their reference counts. Before we get to call update_refcount() to do this last step s->free_cluster_index is already pointing to the next cluster after the ones we are trying to allocate. During update_refcount() it may happen however that we also need to allocate a new refcount block in order to store the refcounts of these new clusters (and to complicate things further that may also require us to grow the refcount table). After all this we don't know if the clusters that we originally tried to allocate are still available, so we return -EAGAIN to ask the caller to restart the search for free clusters. This is what can happen in a common scenario: 1) We want to allocate a new cluster and we see that cluster N is free. 2) We try to increase N's refcount but all refcount blocks are full, so we allocate a new one at N+1 (where s->free_cluster_index was pointing at). 3) Once we're done we return -EAGAIN to look again for a free cluster, but now s->free_cluster_index points at N+2, so that's the one we allocate. Cluster N remains unallocated and we have a hole in the qcow2 file. This can be reproduced easily: qemu-img create -f qcow2 -o cluster_size=512 hd.qcow2 1M qemu-io -c 'write 0 124k' hd.qcow2 After this the image has 132608 bytes (256 clusters), and the refcount block is full. If we write 512 more bytes it should allocate two new clusters: the data cluster itself and a new refcount block. qemu-io -c 'write 124k 512' hd.qcow2 However the image has now three new clusters (259 in total), and the first one of them is empty (and unallocated): dd if=hd.qcow2 bs=512c skip=256 count=1 | hexdump -C If we write larger amounts of data in the last step instead of the 512 bytes used in this example we can create larger holes in the qcow2 file. What this patch does is reset s->free_cluster_index to its previous value when alloc_refcount_block() returns -EAGAIN. This way the caller will try to allocate again the original clusters if they are still free. The output of iotest 026 also needs to be updated because now that images have no holes some tests fail at a different point and the number of leaked clusters is different.

2018-03-23qapi: Force UTF8 encoding when parsing qapi filesEric Blake
Commit d4e5ec877 already fixed things to work around Python 3's lame bug of having LC_ALL=C not be 8-bit clean, when parsing the main QMP qapi files; but failed to do likewise in the tests directory. As a result, running 'LC_ALL=C make check' fails on escape-too-big and unicode-str when using python 3 with a nasty stack trace instead of the intended graceful error message that QAPI doesn't yet support 8-bit data (the two tests contain Unicode é, when parsed in UTF-8; they represent something different when parsed in a proper single-byte C locale, but that doesn't matter to the error message printed out, provided that brain-dead Python hasn't first choked on the input instead of being 8-bit clean). Ideally, we'd teach the qapi generator scripts to automatically slurp things in using UTF-8 regardless of locale, and to honor content that is not limited to 7 bit data rather than gracefully erroring out; but until then, since our graceful error depends on python parsing 8-bit data (even if nothing we generate uses 8-bit data), our quick fix is to use the right locale when running these tests.

2018-03-23Revert "monitor: enable IO thread for (qmp & !mux) typed"Peter Xu
This reverts commit 3fd2457d18edf5736f713dfe1ada9c87a9badab1. Enabling OOB caused several iotests failures; due to the imminent 2.12 release, the safest action is to disable OOB for now. If other patches fix the issues that iotests exposed, it may be turned back on in time for the release, otherwise it will be 2.13 material; either way, the framework changes not reverted now do not hurt if they remain as part of the 2.12 release. Additionally, revert the tests in the patch 02130314d8 ("qmp: introduce QMPCapability", 2018-03-19), as both parts must be reverted at once to keep 'make check' passing.

2018-03-19qapi: introduce new cmd option "allow-oob"Peter Xu
Here "oob" stands for "Out-Of-Band". When "allow-oob" is set, it means the command allows out-of-band execution. The "oob" idea is proposed by Markus Armbruster in following thread: https://lists.gnu.org/archive/html/qemu-devel/2017-09/msg02057.html This new "allow-oob" boolean will be exposed by "query-qmp-schema" as well for command entries, so that QMP clients can know which commands can be used in out-of-band calls. For example the command "migrate" originally looks like: {"name": "migrate", "ret-type": "17", "meta-type": "command", "arg-type": "86"} And it'll be changed into: {"name": "migrate", "ret-type": "17", "allow-oob": false, "meta-type": "command", "arg-type": "86"} This patch only provides the QMP interface level changes. It does not contain the real out-of-band execution implementation yet.

2018-03-19qmp: introduce QMPCapabilityPeter Xu
There were no QMP capabilities defined. Define the first capability, "oob", to allow out-of-band messages. After this patch, we will allow QMP clients to enable QMP capabilities when sending the first "qmp_capabilities" command. Originally we are starting QMP session with no arguments like: { "execute": "qmp_capabilities" } Now we can enable some QMP capabilities using (take OOB as example, which is the only capability that we support): { "execute": "qmp_capabilities", "arguments": { "enable": [ "oob" ] } } When the "arguments" key is not provided, no capability is enabled. For capability "oob", the monitor needs to be run on a dedicated IO thread, otherwise the command will fail. For example, trying to enable OOB on a MUXed typed QMP monitor will fail. One thing to mention is that QMP capabilities are per-monitor, and also when the connection is closed due to some reason, the capabilities will be reset. Also, touch up qmp-test.c to test the new bits.

2018-03-19iotests: Avoid realpath, for CentOS 6Eric Blake
CentOS 6 lacks a realpath binary on the base install, which makes all iotests runs fail since the 2.11 release: 001 - output mismatch (see 001.out.bad) ./check: line 815: realpath: command not found diff: missing operand after `/home/dummy/qemu/tests/qemu-iotests/001.out' diff: Try `diff --help' for more information. Many of the uses of 'realpath' in the check script were being used on the output of 'type -p' - but that is already an absolute file name. While a canonical name can often be shorter (realpath gets rid of /../), it can also be longer (due to symlink expansion); and we really don't care if the name is canonical, merely that it was an executable file with an absolute path. These were broken in commit cceaf1db. The remaining use of realpath was to convert a possibly relative filename into an absolute one before calling diff to make it easier to copy-and-paste the filename for moving the .bad file into place as the new reference file even when running iotests out-of-tree (see commit 93e53fb6), but $PWD can achieve the same purpose.

2018-03-19block/mirror: change the semantic of 'force' of block-job-cancelLiang Li
When doing drive mirror to a low speed shared storage, if there was heavy BLK IO write workload in VM after the 'ready' event, drive mirror block job can't be canceled immediately, it would keep running until the heavy BLK IO workload stopped in the VM. Libvirt depends on the current block-job-cancel semantics, which is that when used without a flag after the 'ready' event, the command blocks until data is in sync. However, these semantics are awkward in other situations, for example, people may use drive mirror for realtime backups while still wanting to use block live migration. Libvirt cannot start a block live migration while another drive mirror is in progress, but the user would rather abandon the backup attempt as broken and proceed with the live migration than be stuck waiting for the current drive mirror backup to finish. The drive-mirror command already includes a 'force' flag, which libvirt does not use, although it documented the flag as only being useful to quit a job which is paused. However, since quitting a paused job has the same effect as abandoning a backup in a non-paused job (namely, the destination file is not in sync, and the command completes immediately), we can just improve the documentation to make the force flag obviously useful.

2018-03-19blockjobs: add block_job_verb permission tableJohn Snow
Which commands ("verbs") are appropriate for jobs in which state is also somewhat burdensome to keep track of. As of this commit, it looks rather useless, but begins to look more interesting the more states we add to the STM table. A recurring theme is that no verb will apply to an 'undefined' job. Further, it's not presently possible to restrict the "pause" or "resume" verbs any more than they are in this commit because of the asynchronous nature of how jobs enter the PAUSED state; justifications for some seemingly erroneous applications are given below. ===== Verbs ===== Cancel: Any state except undefined. Pause: Any state except undefined; 'created': Requests that the job pauses as it starts. 'running': Normal usage. (PAUSED) 'paused': The job may be paused for internal reasons, but the user may wish to force an indefinite user-pause, so this is allowed. 'ready': Normal usage. (STANDBY) 'standby': Same logic as above. Resume: Any state except undefined; 'created': Will lift a user's pause-on-start request. 'running': Will lift a pause request before it takes effect. 'paused': Normal usage. 'ready': Will lift a pause request before it takes effect. 'standby': Normal usage. Set-speed: Any state except undefined, though ready may not be meaningful. Complete: Only a 'ready' job may accept a complete request. ======= Changes ======= (1) To facilitate "nice" error checking, all five major block-job verb interfaces in blockjob.c now support an errp parameter: - block_job_user_cancel is added as a new interface. - block_job_user_pause gains an errp paramter - block_job_user_resume gains an errp parameter - block_job_set_speed already had an errp parameter. - block_job_complete already had an errp parameter. (2) block-job-pause and block-job-resume will no longer no-op when trying to pause an already paused job, or trying to resume a job that isn't paused. These functions will now report that they did not perform the action requested because it was not possible. iotests have been adjusted to address this new behavior. (3) block-job-complete doesn't worry about checking !block_job_started, because the permission table guards against this. (4) test-bdrv-drain's job implementation needs to announce that it is 'ready' now, in order to be completed.

2018-03-19iotests: add pause_waitJohn Snow
Split out the pause command into the actual pause and the wait. Not every usage presently needs to resubmit a pause request. The intent with the next commit will be to explicitly disallow redundant or meaningless pause/resume requests, so the tests need to become more judicious to reflect that.

2018-03-19blockjobs: add status enumJohn Snow
We're about to add several new states, and booleans are becoming unwieldly and difficult to reason about. It would help to have a more explicit bookkeeping of the state of blockjobs. To this end, add a new "status" field and add our existing states in a redundant manner alongside the bools they are replacing: UNDEFINED: Placeholder, default state. Not currently visible to QMP unless changes occur in the future to allow creating jobs without starting them via QMP. CREATED: replaces !!job->co && paused && !busy RUNNING: replaces effectively (!paused && busy) PAUSED: Nearly redundant with info->paused, which shows pause_count. This reports the actual status of the job, which almost always matches the paused request status. It differs in that it is strictly only true when the job has actually gone dormant. READY: replaces job->ready. STANDBY: Paused, but job->ready is true. New state additions in coming commits will not be quite so redundant: WAITING: Waiting on transaction. This job has finished all the work it can until the transaction converges, fails, or is canceled. PENDING: Pending authorization from user. This job has finished all the work it can until the job or transaction is finalized via block_job_finalize. This implies the transaction has converged and left the WAITING phase. ABORTING: Job has encountered an error condition and is in the process of aborting. CONCLUDED: Job has ceased all operations and has a return code available for query and may be dismissed via block_job_dismiss. NULL: Job has been dismissed and (should) be destroyed. Should never be visible to QMP. Some of these states appear somewhat superfluous, but it helps define the expected flow of a job; so some of the states wind up being synchronous empty transitions. Importantly, jobs can be in only one of these states at any given time, which helps code and external users alike reason about the current condition of a job unambiguously.

2018-03-19blockjobs: model single jobs as transactionsJohn Snow
model all independent jobs as single job transactions. It's one less case we have to worry about when we add more states to the transition machine. This way, we can just treat all job lifetimes exactly the same. This helps tighten assertions of the STM graph and removes some conditionals that would have been needed in the coming commits adding a more explicit job lifetime management API.
