afr: check for non-zero call_count before doing a stack wind
When one of the bricks of a 1x2 replicate volume is down, writes to the volume is causing a race between afr_flush_wrapper() and afr_flush_cbk(). The latter frees up the call_frame's local variables in the unwind, while the former accesses them in the for loop and sending a stack wind the second time. This causes the FUSE mount process (glusterfs) toa receive a SIGSEGV when the corresponding unwind is hit. This patch adds the call_count check which was removed when afr_flush_wrapper() was introduced in commit 29619b4e Change-Id: I87d12ef39ea61cc4c8244c7f895b7492b90a7042 BUG: 988182 Signed-off-by: Ravishankar N <> Reviewed-on: Tested-by: Gluster Build System <> Reviewed-by: Pranith Kumar Karampuri <> Reviewed-by: Anand Avati <>
