Subject: [PATCH 0/8] migration fixes
Date: Mon, 18 Sep 2023 14:28:14 -0300 [thread overview]
Message-ID: <20230918172822.19052-1-farosas@suse.de> (raw)
This series contains fixes for the two currently know failures that
show up in migration tests plus a set of fixes for some theoretical
race conditions around QEMUFile handling.
Patch 1 addresses the issue found in the postcopy/preempt/plain test:
https://gitlab.com/qemu-project/qemu/-/issues/1886
Patch 7 fixes a rare crash during the postocpy/preempt/recovery/plain test:
Thread 7 "return path" received signal SIGSEGV, Segmentation fault.
0x00005555560e4893 in qemu_file_get_error_obj (f=0x0, errp=0x0) at ../migration/qemu-file.c:154
154 return f->last_error;
CI run: https://gitlab.com/farosas/qemu/-/pipelines/1008652837
Fabiano Rosas (7):
migration: Fix possible race when setting rp_state.error
migration: Fix possible races when shutting down the return path
migration: Fix possible race when shutting down to_dst_file

Peter Xu (1):
