That means, given a\nlarge s_log_groups_per_flex value like 36, groups_per_flex \u003d 1 \u003c\u003c 36\nis essentially 1 \u003c\u003c 4 \u003d 16, rather than 0. This will bypass the check,\nleaving s_log_groups_per_flex and groups_per_flex inconsistent.\n\n2) The sanity check relies on undefined behavior, i.e., oversized shift.\nA standard-confirming C compiler could rewrite the check in unexpected\nways. Consider the following equivalent form, assuming groups_per_flex\nis unsigned for simplicity.\n\n\tgroups_per_flex \u003d 1 \u003c\u003c sbi-\u003es_log_groups_per_flex;\n\tif (groups_per_flex \u003d\u003d 0 || groups_per_flex \u003d\u003d 1) {\n\nWe compile the code snippet using Clang 3.0 and GCC 4.6. Clang will\ncompletely optimize away the check groups_per_flex \u003d\u003d 0, leaving the\npatched code as vulnerable as the original. GCC keeps the check, but\nthere is no guarantee that future versions will do the same.\n\nSigned-off-by: Xi Wang \u003cxi.wang@gmail.com\u003e\nSigned-off-by: \"Theodore Ts\u0027o\" \u003ctytso@mit.edu\u003e\nCc: stable@vger.kernel.org\n" }, { "commit": "e4e11180dfa545233e5145919b75b7fac88638df", "tree": "bfdb18eee49aa55fd3d6170a422164e772736a1b", "parents": [ "37cfc3f67db9f2d907f6bfcfae590cdbbef623e8", "adc0e91ab142abe93f5b0d7980ada8a7676231fe" ], "author": { "name": "Linus Torvalds", "email": "torvalds@linux-foundation.org", "time": "Mon Jan 09 17:37:37 2012 -0800" }, "committer": { "name": "Linus Torvalds", "email": "torvalds@linux-foundation.org", "time": "Mon Jan 09 17:37:37 2012 -0800" }, "message": "Merge branch \u0027for-linus\u0027 of git://git.kernel.org/pub/scm/linux/kernel/git/viro/vfs\n\n* \u0027for-linus\u0027 of git://git.kernel.org/pub/scm/linux/kernel/git/viro/vfs:\n vfs: new helper - d_make_root()\n dcache: use a dispose list in select_parent\n ceph: d_alloc_root() may fail\n ext4: fix failure exits\n isofs: inode leak on mount failure\n" }, { "commit": "94bf608a18fa4421315275a81c5489734599297a", "tree": "69b0022e0f47a5af7888c7e97459302373bfa338", "parents": [ "8fdd8c49fe50394fef3e193db27222cb03c2b212" ], "author": { "name": "Al Viro", "email": "viro@zeniv.linux.org.uk", "time": "Mon Jan 09 15:53:24 2012 -0500" }, "committer": { "name": "Al Viro", "email": "viro@zeniv.linux.org.uk", "time": "Mon Jan 09 15:57:20 2012 -0500" }, "message": "ext4: fix failure exits\n\na) leaking root dentry is bad\nb) in case of failed ext4_mb_init() we don\u0027t want to do ext4_mb_release()\nc) OTOH, in the same case we *do* want ext4_ext_release()\n\nSigned-off-by: Al Viro \u003cviro@zeniv.linux.org.uk\u003e\n" }, { "commit": "ac69e0928054ff29a5049902fb477f9c7605c773", "tree": "05be6b9285186823452e0adeffe40e1dfee6e354", "parents": [ "9e203936eac786f9268d6a13e6442d2accef1829", "302bf2f3259948c93361d501b04a5ed69c3bd4f8" ], "author": { "name": "Linus Torvalds", "email": "torvalds@linux-foundation.org", "time": "Mon Jan 09 12:51:21 2012 -0800" }, "committer": { "name": "Linus Torvalds", "email": "torvalds@linux-foundation.org", "time": "Mon Jan 09 12:51:21 2012 -0800" }, "message": "Merge branch \u0027for_linus\u0027 of git://git.kernel.org/pub/scm/linux/kernel/git/jack/linux-fs\n\n* \u0027for_linus\u0027 of git://git.kernel.org/pub/scm/linux/kernel/git/jack/linux-fs:\n ext2/3/4: delete unneeded includes of module.h\n ext{3,4}: Fix potential race when setversion ioctl updates inode\n udf: Mark LVID buffer as uptodate before marking it dirty\n ext3: Don\u0027t warn from writepage when readonly inode is spotted after error\n jbd: Remove j_barrier mutex\n reiserfs: Force inode evictions before umount to avoid crash\n reiserfs: Fix quota mount option parsing\n udf: Treat symlink component of type 2 as /\n udf: Fix deadlock when converting file from in-ICB one to normal one\n udf: Cleanup calling convention of inode_getblk()\n ext2: Fix error handling on inode bitmap corruption\n ext3: Fix error handling on inode bitmap corruption\n ext3: replace ll_rw_block with other functions\n ext3: NULL dereference in ext3_evict_inode()\n jbd: clear revoked flag on buffers before a new transaction started\n ext3: call ext3_mark_recovery_complete() when recovery is really needed\n" }, { "commit": "302bf2f3259948c93361d501b04a5ed69c3bd4f8", "tree": "22ccdf5774a28476745a94532b5ce2c2cc454d98", "parents": [ "6c2155b9cc5a193e85194bbeaae2e2e4512dd597" ], "author": { "name": "Paul Gortmaker", "email": "paul.gortmaker@windriver.com", "time": "Wed Jan 04 15:59:47 2012 -0500" }, "committer": { "name": "Jan Kara", "email": "jack@suse.cz", "time": "Mon Jan 09 13:52:10 2012 +0100" }, "message": "ext2/3/4: delete unneeded includes of module.h\n\nDelete any instances of include module.h that were not strictly\nrequired.
