glusterfs.git/tests/bugs/readdir-ahead/bug-1670253-consistent-metadata.t, branch v5.7 readdir-ahead: do not zero-out iatt in fop cbk 2019-02-04T14:52:59+00:00 Ravishankar N ravishankar@redhat.com 2019-01-29T06:21:16+00:00 3f05fb00a090686bbdb0b467cec1f3647903b851 ...when ctime is zero. ia_type and ia_gfid always need to be non-zero for things to work correctly. Problem: Commit c9bde3021202f1d5c5a2d19ac05a510fc1f788ac zeroed out the iatt buffer in the cbks of modification fops before unwinding if the ctime in the buffer was zero. This was causing the fops to fail: noticeable when AFR's 'consistent-metadata' option was enabled. (AFR zeros out the ctime when the option is set. See commit 4c4624c9bad2edf27128cb122c64f15d7d63bbc8). Fixes: -Do not zero out the ia_type and ia_gfid of the iatt buff under any circumstance. -Also, fixed _rda_inode_ctx_update_iatts() to always update these values from the incoming buf when ctime is zero. Otherwise we end up with zero ia_type and ia_gfid the first time the function is called *and* the incoming buf has ctime set to zero. fixes: bz#1665145 Reported-By:Michael Hanselmann <public@hansmi.ch> Change-Id: Ib72228892d42c3513c19fc6dfb543f2aa3489eca Signed-off-by: Ravishankar N <ravishankar@redhat.com> (cherry picked from commit 09db11b0c020bc79d493c6d7e7ea4f3beb000c68) 
...when ctime is zero. ia_type and ia_gfid always need to be non-zero
for things to work correctly.

Problem:
Commit c9bde3021202f1d5c5a2d19ac05a510fc1f788ac zeroed out the iatt
buffer in the cbks of modification fops before unwinding if the ctime in
the buffer was zero. This was causing the fops to fail: noticeable when
AFR's 'consistent-metadata' option was enabled. (AFR zeros out the ctime
when the option is set. See commit
4c4624c9bad2edf27128cb122c64f15d7d63bbc8).

Fixes:
-Do not zero out the ia_type and ia_gfid of the iatt buff under any
circumstance.
-Also, fixed _rda_inode_ctx_update_iatts() to always update these values from
the incoming buf when ctime is zero. Otherwise we end up with zero
ia_type and ia_gfid the first time the function is called *and* the
incoming buf has ctime set to zero.
