umask broken on master

Bug Blocker Resolved Fixed Lai Siyao Christopher Morrone LB Fri, 12 Apr 2013 22:52:38 +0000 Fri, 19 Apr 2013 12:17:26 +0000 Fri, 19 Apr 2013 12:17:26 +0000 Lustre 2.4.0 Lustre 2.4.0 0 4 <p>Perhaps another swabbing bug introduced in the umask handling code when it was recently reworked? An x86_64 client running lustre 2.1.4-3chaos does not see the umask problem. So either the server behaves differently for the older client, or the different is the architecture of the client.</p> <p>Lai</p> <p>Could you please look into this one?</p> <p>Thanks</p> <p>Peter</p> <p>It looks like mdt_rec_create.cr_umask uses the rr_padding_3 field from the template struct mdt_rec_reint, but lustre_swab_mdt_rec_reint() was never updated to swab that field.</p> <p>Both rr_flags_h and rr_umask are missing in mdt_rec_reint, the patch is on <a href="http://review.whamcloud.com/#change,6054" class="external-link" target="_blank" rel="nofollow noopener">http://review.whamcloud.com/#change,6054</a></p> <p>Lai, your patch takes care of the umask problem.
