REVIEW: http://review.gluster.org/15168 (cluster/afr: copy loc before passing to syncop) posted (#1) for review on release-3.7 by Oleksandr Natalenko (oleksandr)
COMMIT: http://review.gluster.org/15168 committed in release-3.7 by Pranith Kumar Karampuri (pkarampu) ------ commit 318aacabbc482bcc2e1686988a77ad0bc054837e Author: Pranith Kumar K <pkarampu> Date: Tue Aug 2 15:19:00 2016 +0530 cluster/afr: copy loc before passing to syncop Problem: When io-threads is enabled on the client side, io-threads destroys the call-stub in which the loc is stored as soon as the c-stack unwinds. Because afr is creating a syncop with the address of loc passed in setxattr by the time syncop tries to access it, io-threads would have already freed the call-stub. This will lead to crash. Fix: Copy loc to frame->local and use it's address. > Reviewed-on: http://review.gluster.org/15070 > Smoke: Gluster Build System <jenkins.org> > CentOS-regression: Gluster Build System <jenkins.org> > NetBSD-regression: NetBSD Build System <jenkins.org> > Reviewed-by: Ravishankar N <ravishankar> BUG: 1367305 Change-Id: I16987e491e24b0b4e3d868a6968e802e47c77f7a Signed-off-by: Pranith Kumar K <pkarampu> Signed-off-by: Oleksandr Natalenko <oleksandr> Reviewed-on: http://review.gluster.org/15168 Reviewed-by: Ravishankar N <ravishankar> Smoke: Gluster Build System <jenkins.org> CentOS-regression: Gluster Build System <jenkins.org> NetBSD-regression: NetBSD Build System <jenkins.org>
