- Refactor the incore extent map manipulations to use a cursor instead of directly modifying extent data. - Refactor the incore extent map cursor to use an in-memory btree instead of a single high-order allocation. This eliminates a major source of complaints about insufficient memory when opening a heavily fragmented file into a system whose memory is also heavily fragmented. - Fix a longstanding bug where deleting a file with a complex extended attribute btree incorrectly handled memory pointers, which could lead to memory corruption. - Improve metadata validation to eliminate crashing problems found while fuzzing xfs. - Move the error injection tag definitions into libxfs to be shared with userspace components. - Fix some log recovery bugs where we'd underflow log block position vector and incorrectly fail log recovery. - Drain the buffer lru after log recovery to force recovered buffers back through the verifiers after mount. On a v4 filesystem the log never attaches verifiers during log replay (v5 does), so we could end up with buffers marked verified but without having ever been verified. - Fix various other bugs. - Introduce the first part of a new online fsck tool. The new fsck tool will be able to iterate every piece of metadata in the filesystem to look for obvious errors and corruptions. In the next release cycle the checking will be extended to cross-reference with the other fs metadata, so this feature should only be used by the developers in the mean time. -----BEGIN PGP SIGNATURE----- Version: GnuPG v1 iQIcBAABCgAGBQJaBdbZAAoJEPh/dxk0SrTrKoUP/RroXfZX3PSn3Z0Qo99E6Ev9 +Z3CoJSSfXPJtSPBh6mUgonzzpKMqoN3kj8ZezYRLaeSEo+36ZkBtdLOb/8PydOZ 4agNvtGDhwt88+1vSAccbT6l4wB/Z16NfzGaVN4dioHF1LpC4rORqdEuoq5xXxzo JVjuwTbz8uPSCpTTukzll9XFghvvj+YXm20MgEOCJiR5uULlGW5gZ38mNCmS76Bk Nks5dNSmNzlGwIpwsVmthd0s0jwj8WeQPnUOv27naRm4J6GOvB5gE8vn15e07AHT EqeTTHy25lnJhmpazphvDwbN3B6UdWCHGoG8ll2B+45pZegS7SKt4G6b4ittHq9x +ErCHFElrNCO77QDQmQoXHy6+DJV/Rdnyb5K575rA91TAb0q2C7OP6vQt6oV0rDM obZ7M3MvW9jBVn9A07Hdsk4+J2/SYW0jf5Dv4O69U1KuvZYUES2B++PL+u7pdTpy JPg1+pWO+AgxRKQNviFFzRwQDPE3JSp854TCE/5D/59h2ZeSWg+g4ZH5jcLjKwKM +uHbJgqOdgk2/WPHiEFCOouom3RUxdE1Yg7S87sbaQC4iU5oWWQ8Kenl2AUyNQEN yaU/leq6rqX3Z2z+T70ujWSvh5xl07YHLW3LJszZMi4w+i8C7c0lIX9F8CNu26Cf yJApOvMWhhY3Mf7Gn1l5 =vQrJ -----END PGP SIGNATURE----- Merge tag 'xfs-4.15-merge-1' of git://git.kernel.org/pub/scm/fs/xfs/xfs-linux Pull xfs updates from Darrick Wong: "xfs: great scads of new stuff for 4.15. This merge cycle, we're making some substantive changes to XFS. The in-core extent mappings have been refactored to use proper iterators and a btree to handle heavily fragmented files without needing high-order memory allocations; some important log recovery bug fixes; and the first part of the online fsck functionality. (The online fsck feature is disabled by default and more pieces of it will be coming in future release cycles.) This giant pile of patches has been run through a full xfstests run over the weekend and through a quick xfstests run against this morning's master, with no major failures reported. New in this version: - Refactor the incore extent map manipulations to use a cursor instead of directly modifying extent data. - Refactor the incore extent map cursor to use an in-memory btree instead of a single high-order allocation. This eliminates a major source of complaints about insufficient memory when opening a heavily fragmented file into a system whose memory is also heavily fragmented. - Fix a longstanding bug where deleting a file with a complex extended attribute btree incorrectly handled memory pointers, which could lead to memory corruption. - Improve metadata validation to eliminate crashing problems found while fuzzing xfs. - Move the error injection tag definitions into libxfs to be shared with userspace components. - Fix some log recovery bugs where we'd underflow log block position vector and incorrectly fail log recovery. - Drain the buffer lru after log recovery to force recovered buffers back through the verifiers after mount.
