Hi all, Here's v3 of the verifier magic value fixup series. This version adds a couple more patches to separate and convert the allocation btree buffer verifier to the new magic value verification scheme. The allocbt is similar to the inobt verifier in that it currently uses the same verifier code for multiple magic values. This change allows the verifier to ensure that bnobt/cntbt blocks have the appropriate magic value for v4 and v5 filesytems. The only other change from v2 is a fixup to include parameter names in function declarations. Thoughts, reviews, flames appreciated. Brian v3: - Fix function declarations to include parameter names. - Convert allocbt buffer verifier. v2: https://marc.info/?l=linux-xfs&m=154894958207167&w=2 - Include djwong's ->b_ops patch w/ modifications. - Added patch to fix up existing cpu endian magic checks, fold in typo fix. - Replace static inline magic verifier helper with out of line variant, kill macro. - Store on-disk byte order magics in ->b_ops. - Added patch to refactor common xfs_da3_blkinfo checks. v1: https://marc.info/?l=linux-xfs&m=154878684317178&w=2 - Remove endian conversion from helper. - Drop finobt bad magic mitigation patch. - Additional verifier magic fixups. - Add verifier name typo fixup. rfcv2: https://marc.info/?l=linux-xfs&m=154868884311668&w=2 - Split off finobt verifier into separate patch, assign it appropriately. - Created helpers for xfs_buf_ops magic value verification. - Added error mitigation patch for problematic finobt blocks. rfcv1: https://marc.info/?l=linux-xfs&m=154834528212262&w=2 Brian Foster (8): xfs: always check magic values in on-disk byte order xfs: create a separate finobt verifier xfs: distinguish between inobt and finobt magic values xfs: split up allocation btree verifier xfs: distinguish between bnobt and cntbt magic values xfs: use verifier magic field in dir2 leaf verifiers xfs: miscellaneous verifier magic value fixups xfs: factor xfs_da3_blkinfo verification into common helper Darrick J.
