2017-05-09sockets: Rename SocketAddress to SocketAddressLegacyMarkus Armbruster1-36/+36
The next commit will rename SocketAddressFlat to SocketAddress, and the commit after that will replace most uses of SocketAddressLegacy by SocketAddress, replacing most of this commit's renames right back. Note that checkpatch emits a few "line over 80 characters" warnings. The long lines are all temporary; the SocketAddressLegacy replacement will shorten them again.

2017-05-09test-qga: Actually test 0xff sync bytesEric Blake2-7/+42
Commit 62c39b3 introduced test-qga, and at face value, appears to be testing the 'guest-sync' behavior that is recommended for guests in sending 0xff to QGA to force the parser to reset. But this aspect of the test has never actually done anything: the qmp_fd() call chain converts its string argument into QObject, then converts that QObject back to the actual string that is sent over the wire - and the conversion process silently drops the 0xff byte from the string sent to QGA, thus never resetting the QGA parser. An upcoming patch will get rid of the wasteful round trip through QObject, at which point the string in test-qga will be directly sent over the wire. But fixing qmp_fd() to actually send 0xff over the wire is not all we have to do - the actual QMP parser loudly complains that 0xff is not valid JSON, and sends an error message _prior_ to actually parsing the 'guest-sync' or 'guest-sync-delimited' command. With 'guest-sync', we cannot easily tell if this error message is a result of our command - which is WHY we invented the 'guest-sync-delimited' command. So for the testsuite, fix things to only check 0xff behavior on 'guest-sync-delimited', and to loop until we've consumed all garbage prior to the requested delimiter, which is compatible with the documented actions that a real QGA client is supposed to do. Ideally, we'd fix the QGA JSON parser to silently ignore 0xff rather than sending an error message back, at which point we could enhance this test for 'guest-sync' as well as for 'guest-sync-delimited'. But for the sake of this patch, our testing of 'guest-sync' is no worse than it was pre-patch, because we have never been sending 0xff over the wire in the first place.

2017-04-28qcow2: Allow discard of final unaligned clusterEric Blake2-9/+15
As mentioned in commit 0c1bd46, we ignored requests to discard the trailing cluster of an unaligned image. While discard is an advisory operation from the guest standpoint, (and we are therefore free to ignore any request), our qcow2 implementation exploits the fact that a discarded cluster reads back as 0. As long as we discard on cluster boundaries, we are fine; but that means we could observe non-zero data leaked at the tail of an unaligned image. Enhance iotest 66 to cover this case, and fix the implementation to honor a discard request on the final partial cluster.

2017-04-27iotests: 109: Filter out "len" of failed jobsFam Zheng3-12/+20
Mirror calculates job len from current I/O progress: s->common.len = s->common.offset + (cnt + s->sectors_in_flight) * BDRV_SECTOR_SIZE; The final "len" of a failed mirror job in iotests 109 depends on the subtle timing of the completion of read and write issued in the first mirror iteration. The second iteration may or may not have run when the I/O error happens, resulting in non-deterministic output of the BLOCK_JOB_COMPLETED event text. Similar to what was done in a752e4786, filter out the field to make the test robust.

2017-04-21throttle: make throttle_config(throttle_get_config()) symmetricStefan Hajnoczi1-4/+4
Throttling has a weird property that throttle_get_config() does not always return the same throttling settings that were given with throttle_config(). In other words, the set and get functions aren't symmetric. If .max is 0 then the throttling code assigns a default value of .avg / 10 in throttle_config(). This is an implementation detail of the throttling algorithm. When throttle_get_config() is called the .max value returned should still be 0. Users are exposed to this quirk via "info block" or "query-block" monitor commands. This has caused confusion because it looks like a bug when an unexpected value is reported. This patch hides the .max value adjustment in throttle_get_config() and updates test-throttle.c appropriately.

2017-04-11block: Use bdrv_coroutine_enter to start I/O coroutinesFam Zheng1-5/+5

2017-04-03iotests: fix 097 when run with qcowDaniel P. Berrange5-130/+251
The previous commit: commit a3e1505daec31ef56f0489f8c8fff1b8e4ca92bd Author: Eric Blake <eblake@redhat.com> Date: Mon Dec 5 09:49:34 2016 -0600 qcow2: Don't strand clusters near 2G intervals during commit extended the 097 test case so that it did two passes, once with an internal snapshot, once without. qcow (v1) does not support internal snapshots, so this change broke test 097 when run against qcow. This splits 097 in two, creating a new 176 that tests the internal snapshot codepath, effectively putting 097 back to its content before the above commit.

2017-04-03nbd: Tidy up blockdev-add interfaceMarkus Armbruster1-8/+17
SocketAddress is a simple union, and simple unions are awkward: they have their variant members wrapped in a "data" object on the wire, and require additional indirections in C. I intend to limit its use to existing external interfaces, and convert all internal interfaces to SocketAddressFlat. BlockdevOptionsNbd is an external interface using SocketAddress. We already use SocketAddressFlat elsewhere in blockdev-add. Replace it by SocketAddressFlat while we can (it's new in 2.9) for simplicity and consistency. For example, { "execute": "blockdev-add", "arguments": { "node-name": "foo", "driver": "nbd", "server": { "type": "inet", "data": { "host": "localhost", "port": "12345" } } } } becomes { "execute": "blockdev-add", "arguments": { "node-name": "foo", "driver": "nbd", "server": { "type": "inet", "host": "localhost", "port": "12345" } } } Since the internal interfaces still take SocketAddress, this requires conversion function socket_address_crumple(). It'll go away when I update the interfaces. Unfortunately, SocketAddress is also visible in -drive since 2.8: -drive if=none,driver=nbd,server.type=inet,server.data.host=127.0.0.1,server.data.port=12345 Nobody should be using it, as it's fairly new and has never been documented, so adding still more compatibility gunk to keep it working isn't worth the trouble. You now have to use -drive if=none,driver=nbd,server.type=inet,server.host=127.0.0.1,server.port=12345 Signed-off-by: Markus Armbruster <armbru@redhat.com> Message-id: 1490895797-29094-9-git-send-email-armbru@redhat.com [mreitz: Change iotest 147 accordingly] Because of this interface change, iotest 147 has to be adapted. Unfortunately, we cannot just flatten all of the addresses because nbd-server-start still takes a plain SocketAddress. Therefore, we need both and this is most easily achieved by writing the SocketAddress into the code and flattening it where necessary.

2017-03-30tests/acpi: don't pack a structureMichael S. Tsirkin1-1/+1
There's no reason to pack structures where we don't care about size or padding, this applies to AcpiStdTable in tests/acpi-utils.h. OTOH bios-tables-test happens to be passing the address of a field in this struct to a function that expects a pointer to normally aligned data which results in a SIGBUS on architectures like SPARC that have strict alignment requirements.

The supported blockdev-add is not compatible to its experimental predecessors; bump all Since: tags to 2.9. x-blockdev-remove-medium, x-blockdev-insert-medium and x-blockdev-change need a bit more work, so leave them alone for now.

2017-03-27tests/virtio-9p-test: Don't call le*_to_cpus on fields of packed structPeter Maydell1-2/+2
For a packed struct like 'P9Hdr' the fields within it may not be aligned as much as the natural alignment for their types. This means it is not valid to pass the address of such a field to a function like le32_to_cpus() which operate on uint32_t* and assume alignment. Doing this results in a SIGBUS on hosts like SPARC which have strict alignment requirements. Use ldl_le_p() instead, which is specified to correctly handle unaligned pointers.
