The comments "/* fall through */" are interpreted by compilers and other tools, and they will not issue warnings in such cases. For gcc, the warning is turnend on by -Wimplicit-fallthrough. With this patch, there will be no such warnings in target/mips directory. If such warning appears in future, it should be checked if it is intentional, and, if yes, marked with a comment similar to those from this patch.

2018-08-16libqtest: Improve error reporting for bad read from QEMUMarkus Armbruster1-3/+3
When read() from the qtest socket or the QMP socket fails or EOFs, we report "Broken pipe" and exit(1). This commonly happens when QEMU crashes. It also happens when QEMU refuses to run because the test passed it bad arguments. Sadly, we neglect to report either. Improve this by calling abort() instead of exit(1), so kill_qemu() runs, and reports how QEMU died. This improves error reporting to something like /x86_64/device/introspect/list: Broken pipe tests/libqtest.c:129: kill_qemu() detected QEMU death from signal 6 (Aborted) (dumped core) Three exit() remain in libqtest.c: * In qmp_response(), when we can't parse a QMP reply read from the QMP socket. Change to abort() for consistency. * In qtest_qemu_binary(), when QTEST_QEMU_BINARY isn't in the environment. This can only happen before we start QEMU. Leave alone. * In qtest_init_without_qmp_handshake(), when the fork()ed child fails to execlp(). Leave alone. exit() elsewhere are unlikely due to QEMU dying on us. If that should turn out to be wrong, we can move kill_qemu() from @abrt_hooks to atexit() or something.

2018-08-16tests/libqtest: Improve kill_qemu()Eric Blake1-3/+21
In kill_qemu() we have an assert that checks that the QEMU process didn't dump core: assert(!WCOREDUMP(wstatus)); Unfortunately the WCOREDUMP macro here means the resulting message is not very easy to comprehend on at least some systems: ahci-test: tests/libqtest.c:113: kill_qemu: Assertion `!(((__extension__ (((union { __typeof(wstatus) __in; int __i; }) { .__in = (wstatus) }).__i))) & 0x80)' failed. and it doesn't identify what signal the process took. What's more, WCOREDUMP is not reliable - in some cases, setrlimit() coupled with kernel dump settings can result in the flag not being set. It's better to log ALL death by signal, instead of caring whether a core dump was attempted (although once we know a signal happened, also mentioning if a core dump is present can be helpful). Furthermore, we are NOT detecting EINTR (while EINTR shouldn't be happening if we didn't install signal handlers, it's still better to always be robust). Finally, even non-signal death with a non-zero status is suspicious, since qemu's SIGINT handler is supposed to result in exit(0). Instead of using a raw assert, print the information in an easier to understand way: /i386/ahci/sanity: tests/libqtest.c:129: kill_qemu() detected QEMU death from signal 11 (Segmentation fault) (core dumped) (Of course, the really useful information would be why the QEMU process dumped core in the first place, but we don't have that by the time the test program has picked up the exit status.)

2018-08-16tests: Clean up string interpolation into QMP input (simple cases)Markus Armbruster6-113/+78
When you build QMP input manually like this cmd = g_strdup_printf("{ 'execute': 'migrate'," "'arguments': { 'uri': '%s' } }", uri); rsp = qmp(cmd); g_free(cmd); you're responsible for escaping the interpolated values for JSON. Not done here, and therefore works only for sufficiently nice @uri. For instance, if @uri contained a single "'", qobject_from_vjsonf_nofail() would abort. A sufficiently nasty @uri could even inject unwanted members into the arguments object. Leaving interpolation into JSON to qmp() is more robust: rsp = qmp("{ 'execute': 'migrate', 'arguments': { 'uri': %s } }", uri); It's also more concise. Clean up the simple cases where we interpolate exactly a JSON value. Bonus: gets rid of non-literal format strings.

We have two flavors of vararg usage in qtest: qtest_hmp() etc. work like sprintf(), and qtest_qmp() etc. work like qobject_from_jsonf(). Spell that out in the comments. Also add GCC_FMT_ATTR() to qtest_hmp() etc. so that the compiler can flag incorrect use. We have some cleanup work to do before we can do the same for qtest_qmp() etc. This would get us the same better-than-nothing checking we already have for qobject_from_jsonf(): common incorrect uses of supported conversion specifications will be flagged (e.g. passing a double for %d), but use of unsupported ones won't.

2018-08-16libqtest: Remove qtest_qmp_discard_response() & friendsMarkus Armbruster11-55/+34
qtest_qmp_discard_response(...) is shorthand for qobject_unref(qtest_qmp(...), except it's not actually shorter. Moreover, the presence of these functions encourage sloppy testing. Remove them from libqtest. Add them as macros to the tests that use them, with a TODO comment asking for cleanup.

2018-08-15block: Simplify append_open_options()Alberto Garcia1-5/+2
This function returns a BDS's driver-specific options, excluding also those from its children. Since we have just removed all children options from bs->options there's no need to do this last step. We allow references to children, though ("backing": "node0"), so those we still have to remove. Signed-off-by: Alberto Garcia <berto@igalia.com> Signed-off-by: Kevin Wolf <kwolf@redhat.com>
2018-08-15block: Update bs->options if bdrv_reopen() succeedsAlberto Garcia1-1/+14
If bdrv_reopen() succeeds then bs->explicit_options is updated with the new values, but bs->options never changes. Here's an example: { "execute": "blockdev-add", "arguments": { "driver": "qcow2", "node-name": "hd0", "overlap-check": "all", "file": { "driver": "file", "filename": "hd0.qcow2" } } } After this, both bs->options and bs->explicit_options contain "overlap-check": "all". Now let's change that using qemu-io's reopen command: (qemu) qemu-io hd0 "reopen -o overlap-check=none" After this, bs->explicit_options contains the new value but bs->options still keeps the old one. This patch updates bs->options after a BDS has been successfully reopened. Signed-off-by: Alberto Garcia <berto@igalia.com> Signed-off-by: Kevin Wolf <kwolf@redhat.com>
2018-08-15block: Simplify bdrv_reopen_abort()Alberto Garcia1-5/+4
If a bdrv_reopen_multiple() call fails, then the explicit_options QDict has to be deleted for every entry in the reopen queue. This must happen regardless of whether that entry's bdrv_reopen_prepare() call succeeded or not. This patch simplifies the cleanup code a bit.

2018-08-15block: Remove children options from bs->{options,explicit_options}Alberto Garcia1-0/+11
When bdrv_open_inherit() opens a BlockDriverState the options QDict can contain options for some of its children, passed in the form of child-name.option=value So while each child is opened with that subset of options, those same options remain stored in the parent BDS, leaving (at least) two copies of each one of them ("child-name.option=value" in the parent and "option=value" in the child). Having the children options stored in the parent is unnecessary and it can easily lead to an inconsistent state: $ qemu-img create -f qcow2 hd0.qcow2 10M $ qemu-img create -f qcow2 -b hd0.qcow2 hd1.qcow2 $ qemu-img create -f qcow2 -b hd1.qcow2 hd2.qcow2 $ $QEMU -drive file=hd2.qcow2,node-name=hd2,backing.node-name=hd1 This opens a chain of images hd0 <- hd1 <- hd2. Now let's remove hd1 using block_stream: (qemu) block_stream hd2 0 hd0.qcow2 After this hd2 contains backing.node-name=hd1, which is no longer correct because hd1 doesn't exist anymore. This patch removes all children options from the parent dictionaries at the end of bdrv_open_inherit() and bdrv_reopen_queue_child().
