Lustre crc32c implementation not use final bit inversion

Improvement Blocker Resolved Fixed Andreas Dilger Alexander Boyko Tue, 24 Jan 2012 03:25:22 +0000 Tue, 27 Mar 2012 17:12:53 +0000 Wed, 8 Feb 2012 11:34:16 +0000 Lustre 2.2.0 Lustre 2.2.0 0 3 <p>Alexander,<br/> thanks for the bug report. Fortunately, since the CRC32C feature was landed after the 2.1.0 release, there is still time to fix this before 2.2.0 is released.</p> <p>Can you please describe the difference in the implementation in more detail. Are you planning to submit a patch? </p> <p>Sure, the kernel implementation example is below.</p> <div class="preformatted panel" style="border-width: 1px;"><div class="preformattedContent panelContent"> <pre>crc = crc32c(~0, part1, len1); crc = crc32c(crc, part2, len2); crc = crc32c(crc, part3, len3); crc = ~crc; </pre> </div></div> <p>Lustre implementation doesn`t do crc = ~crc. Simple fix is to add fini_cksum(cksum, cksum_type) at obd_cksum.h and call it after cksum calculation loop at osc_request.c and ost_handler.c.</p> <div class="preformatted panel" style="border-width: 1px;"><div class="preformattedContent panelContent"> <pre>u32 fini_cksum(cksum, cksum_type) { if (cksum_type == OBD_CKSUM_CRC32C) return ~cksum; return cksum; } </pre> </div></div> <p>Alexander</p> <p>I appreciate that this is a simple tweak to the existing code, but it would still expedite us reviewing and landing the correction if you could upload it into gerrit.</p> <p>Thanks</p> <p>Peter</p> <p>patch submitted to <a href="http://review.whamcloud.com/2018" class="external-link" target="_blank" rel="nofollow noopener">http://review.whamcloud.com/2018</a></p> <p>Thanks!</p> <p>Alex</p> <p>Could you please rebase your patch on the tip of master? The landing of the fix for LU1048 should have now addressed the reason behind the autotest failure.</p> <p>Thanks</p> <p>Peter</p> <p>done</p> <p>Thanks Alex!</p> <p>Landed for 2.2</p> <p>Integrated
