2024-09-03tests/qtest/migration: Remove vmstate-static-checker testFabiano Rosas1-11/+6
I fumbled one of my last pull requests when fixing in-tree an issue with commit 87d67fadb9 ("monitor: Stop removing non-duplicated fds"). Basically mixed-up my `git add -p` and `git checkout -p` and committed a piece of test infra that has not been reviewed yet. This has not caused any bad symptoms because the test is not enabled by default anywhere: make check doesn't use two qemu binaries and the CI doesn't have PYTHON set for the compat tests. Besides, the test works fine anyway, it would not break anything. Remove this because it was never intended to be merged.

2024-06-21monitor: Stop removing non-duplicated fdsFabiano Rosas1-5/+10
monitor_fdsets_cleanup() currently has three responsibilities: 1- Remove the fds that have been marked for removal(->removed=true) by qmp_remove_fd(). This is overly complicated, but ok. 2- Remove any file descriptors that have been passed into QEMU and never duplicated[1,2]. A file descriptor without duplicates indicates that no part of QEMU has made use of it. This is problematic because the current implementation does it only if the guest is not running and the monitor is closed. 3- Remove/free fdsets that have become empty due to the above removals. This is ok. The scenario described in (2) is starting to show some cracks now that we're trying to consume fds from the migration code: - Doing cleanup every time the last monitor connection closes works to reap unused fds, but also has the side effect of forcing the management layer to pass the file descriptors again in case of a disconnect/re-connect, if that happened to be the only monitor connection. Another side effect is that removing an fd with qmp_remove_fd() is effectively delayed until the last monitor connection closes. The usage of mon_refcount is also problematic because it's racy. - Checking runstate_is_running() skips the cleanup unless the VM is running and avoids premature cleanup of the fds, but also has the side effect of blocking the legitimate removal of an fd via qmp_remove_fd() if the VM happens to be in another state. This affects qmp_remove_fd() and qmp_query_fdsets() in particular because requesting a removal at a bad time (guest stopped) might cause an fd to never be removed, or to be removed at a much later point in time, causing the query command to continue showing the supposedly removed fd/fdset. Note that file descriptors that *have* been duplicated are owned by the code that uses them and will be removed after qemu_close() is called. Therefore we've decided that the best course of action to avoid the undesired side-effects is to stop managing non-duplicated file descriptors. 1- efb87c1697 ("monitor: Clean up fd sets on monitor disconnect") 2- ebe52b592d ("monitor: Prevent removing fd from set during init") Reviewed-by: Peter Xu <peterx@redhat.com> [fix logic mistake: s/fdset_free/fdset_free_if_empty] Signed-off-by: Fabiano Rosas <farosas@suse.de>

Added a new test api qtest_has_cpu_model() in order to check availability of some cpu models in the current QEMU binary. The specific architecture of the QEMU binary is selected using the QTEST_QEMU_BINARY environment variable. This api would be useful to run tests against some older cpu models after checking if QEMU actually supported these models.

Coverity points out that g_setenv() can fail and we don't check for this in qtest_inproc_init(). In practice this will only fail if a memory allocation failed in setenv() or if the caller passed an invalid architecture name (e.g. one with an '=' in it), so rather than requiring the callsite to check for failure, make g_setenv() failure fatal here, similarly to what we did in commit aca68d95c515.

2023-10-20tests/qtest: Introduce qtest_resolve_machine_aliasFabiano Rosas1-0/+16
The migration tests are being enhanced to test migration between different QEMU versions. A requirement of migration is that the machine type between source and destination matches, including the version. We cannot hardcode machine types in the tests because those change with each release. QEMU provides a machine type alias that has a fixed name, but points to the latest machine type at each release. Add a helper to resolve the alias into the exact machine type. E.g.

2022-05-18tests/qtest: use prctl(PR_SET_PDEATHSIG) as fallback to kill QEMUDaniel P. Berrangé1-0/+17
Although we register a ABRT handler to kill off QEMU when g_assert() triggers, we want an extra safety net. The QEMU process might be non-functional and thus not have responded to SIGTERM. The test script might also have crashed with SEGV, in which case the cleanup handlers won't ever run. Using the Linux specific prctl(PR_SET_PDEATHSIG) syscall, we can ensure that QEMU gets sent SIGKILL as soon as the controlling qtest exits, if nothing else has correctly told it to quit. Note, technically the death signal is sent when the *thread* that called fork() exits. IOW, if you are calling qtest_init() in one thread, letting that thread exit, and then expecting to run qtest_quit() in a different thread, things are not going to work out. Fortunately that is not a scenario that exists in qtests, as pairs of qtest_init and qtest_quit are always called from the same thread. Signed-off-by: Daniel P.

2022-05-18tests/qtest: fix registration of ABRT handler for QEMU cleanupDaniel P. Berrangé1-2/+2
qtest_init registers a hook to cleanup the running QEMU process should g_assert() fire before qtest_quit is called. When the first hook is registered, it is supposed to triggere registration of the SIGABRT handler. Unfortunately the logic in hook_list_is_empty is inverted, so the SIGABRT handler never gets registered, unless 2 or more QEMU processes are run concurrently. This caused qtest to leak QEMU processes anytime g_assert triggers. Signed-off-by: Daniel P.

The QMP commands have a trailing newline, but the response does not. This makes the qtest logs hard to follow as the next QMP command appears in the same line as the previous QMP response.
