It was easier to trigger if\nthere was disk IO and dirty pages at the same time and he bisected it to\ncommit 1fb3f8ca0e92 (\"mm: compaction: capture a suitable high-order page\nimmediately when it is made available\").\n\nThe intention of that patch was to improve high-order allocations under\nmemory pressure after changes made to reclaim in 3.6 drastically hurt\nTHP allocations but the approach was flawed. For Eric, the problem was\nthat page-\u003epfmemalloc was not being cleared for captured pages leading\nto a poor interaction with swap-over-NFS support causing the packets to\nbe dropped. However, I identified a few more problems with the patch\nincluding the fact that it can increase contention on zone-\u003elock in some\ncases which could result in async direct compaction being aborted early.\n\nIn retrospect the capture patch took the wrong approach. What it should\nhave done is mark the pageblock being migrated as MIGRATE_ISOLATE if it\nwas allocating for THP and avoided races that way. While the patch was\nshowing to improve allocation success rates at the time, the benefit is\nmarginal given the relative complexity and it should be revisited from\nscratch in the context of the other reclaim-related changes that have\ntaken place since the patch was first written and tested.

The C standard says \"If one operand has\nunsigned int type, the other operand is converted to unsigned int\", so\nthe compiler is not to blame. As a result, DIV_ROUND_CLOSEST(0, 2U) and\nsimilar operations now return bad values, since the automatic conversion\nof expressions such as \"0 - 2U/2\" to unsigned was not taken into\naccount.\n\nFix by checking for the divisor variable type when deciding which\noperation to perform. This fixes DIV_ROUND_CLOSEST(0, 2U), but still\nreturns bad values for negative dividends divided by unsigned divisors.\nMark the latter case as unsupported.\n\nOne observed effect of this problem is that the s2c_hwmon driver reports\na value of 4198403 instead of 0 if the ADC reads 0.\n\nOther impact is unpredictable. Problem is seen if the divisor is an\nunsigned variable or constant and the dividend is less than (divisor/2).\n\nSigned-off-by: Guenter Roeck \u003clinux@roeck-us.net\u003e\nReported-by: Juergen Beisert \u003cjbe@pengutronix.de\u003e\nTested-by: Juergen Beisert \u003cjbe@pengutronix.de\u003e\nCc: Jean Delvare \u003ckhali@linux-fr.org\u003e\nCc: \u003cstable@vger.kernel.org\u003e\t[3.7.x]\nSigned-off-by: Andrew Morton \u003cakpm@linux-foundation.org\u003e\nSigned-off-by: Linus Torvalds \u003ctorvalds@linux-foundation.org\u003e\n" }, { "commit": "b66c5984017533316fd1951770302649baf1aa33", "tree": "78d1e5fc82a057c62699734602c8e5f7ca86b7a2", "parents": [ "9f9c9cbb60576a1518d0bf93fb8e499cffccf377" ], "author": { "name": "Kees Cook", "email": "keescook@chromium.org", "time": "Thu Dec 20 15:05:16 2012 -0800" }, "committer": { "name": "Linus Torvalds", "email": "torvalds@linux-foundation.org", "time": "Thu Dec 20 17:40:19 2012 -0800" }, "message": "exec: do not leave bprm-\u003einterp on stack\n\nIf a series of scripts are executed, each triggering module loading via\nunprintable bytes in the script header, kernel stack contents can leak\ninto the command line.\n\nNormally execution of binfmt_script and binfmt_misc happens recursively.\nHowever, when modules are enabled, and unprintable bytes exist in the\nbprm-\u003ebuf, execution will restart after attempting to load matching\nbinfmt modules.

This includes places where\n we just return pages to the netfs for reading from the server and where\n accessing the cache fails and we discard the proposed netfs page.\n\nThe bugs in the unfixed state management manifest themselves as oopses like the\nfollowing where the operation completion gets out of sync with return of the\ncookie by the netfs. This is possible because the cache unlocks and returns\nall the netfs pages before recording its completion - which means that there\u0027s\nnothing to stop the netfs discarding them and returning the cookie.\n\n\nFS-Cache: Cookie \u0027NFS.fh\u0027 still has outstanding reads\n------------[ cut here ]------------\nkernel BUG at fs/fscache/cookie.c:519!\ninvalid opcode: 0000 [#1] SMP\nCPU 1\nModules linked in: cachefiles nfs fscache auth_rpcgss nfs_acl lockd sunrpc\n\nPid: 400, comm: kswapd0 Not tainted 3.1.0-rc7-fsdevel+ #1090 /DG965RY\nRIP: 0010:[\u003cffffffffa007050a\u003e] [\u003cffffffffa007050a\u003e] __fscache_relinquish_cookie+0x170/0x343 [fscache]\nRSP: 0018:ffff8800368cfb00 EFLAGS: 00010282\nRAX: 000000000000003c RBX: ffff880023cc8790 RCX: 0000000000000000\nRDX: 0000000000002f2e RSI: 0000000000000001 RDI: ffffffff813ab86c\nRBP: ffff8800368cfb50 R08: 0000000000000002 R09: 0000000000000000\nR10: ffff88003a1b7890 R11: ffff88001df6e488 R12: ffff880023d8ed98\nR13: ffff880023cc8798 R14: 0000000000000004 R15: ffff88003b8bf370\nFS: 0000000000000000(0000) GS:ffff88003bd00000(0000) knlGS:0000000000000000\nCS: 0010 DS: 0000 ES: 0000 CR0: 000000008005003b\nCR2: 00000000008ba008 CR3: 0000000023d93000 CR4: 00000000000006e0\nDR0: 0000000000000000 DR1: 0000000000000000 DR2: 0000000000000000\nDR3: 0000000000000000 DR6: 00000000ffff0ff0 DR7: 0000000000000400\nProcess kswapd0 (pid: 400, threadinfo ffff8800368ce000, task ffff88003b8bf040)\nStack:\n ffff88003b8bf040 ffff88001df6e528 ffff88001df6e528 ffffffffa00b46b0\n ffff88003b8bf040 ffff88001df6e488 ffff88001df6e620 ffffffffa00b46b0\n ffff88001ebd04c8 0000000000000004 ffff8800368cfb70 ffffffffa00b2c91\nCall Trace:\n [\u003cffffffffa00b2c91\u003e] nfs_fscache_release_inode_cookie+0x3b/0x47 [nfs]\n [\u003cffffffffa008f25f\u003e] nfs_clear_inode+0x3c/0x41 [nfs]\n [\u003cffffffffa0090df1\u003e] nfs4_evict_inode+0x2f/0x33 [nfs]\n [\u003cffffffff810d8d47\u003e] evict+0xa1/0x15c\n [\u003cffffffff810d8e2e\u003e] dispose_list+0x2c/0x38\n [\u003cffffffff810d9ebd\u003e] prune_icache_sb+0x28c/0x29b\n [\u003cffffffff810c56b7\u003e] prune_super+0xd5/0x140\n [\u003cffffffff8109b615\u003e] shrink_slab+0x102/0x1ab\n [\u003cffffffff8109d690\u003e] balance_pgdat+0x2f2/0x595\n [\u003cffffffff8103e009\u003e] ? process_timeout+0xb/0xb\n [\u003cffffffff8109dba3\u003e] kswapd+0x270/0x289\n [\u003cffffffff8104c5ea\u003e] ? __init_waitqueue_head+0x46/0x46\n [\u003cffffffff8109d933\u003e] ? balance_pgdat+0x595/0x595\n [\u003cffffffff8104bf7a\u003e] kthread+0x7f/0x87\n [\u003cffffffff813ad6b4\u003e] kernel_thread_helper+0x4/0x10\n [\u003cffffffff81026b98\u003e] ? finish_task_switch+0x45/0xc0\n [\u003cffffffff813abcdd\u003e] ? retint_restore_args+0xe/0xe\n [\u003cffffffff8104befb\u003e] ? __init_kthread_worker+0x53/0x53\n [\u003cffffffff813ad6b0\u003e] ? gs_change+0xb/0xb\n\nSigned-off-by: David Howells \u003cdhowells@redhat.com\u003e\n" }, { "commit": "ef46ed888efb1e8da33be5d33c9b54476289a43b", "tree": "d538dc01a075162f95da416da1fb5d6fd676445a", "parents": [ "37491a1339df26259b06dfa33f30e574e9e52034" ], "author": { "name": "David Howells", "email": "dhowells@redhat.com", "time": "Thu Dec 20 21:52:35 2012 +0000" }, "committer": { "name": "David Howells", "email": "dhowells@redhat.com", "time": "Thu Dec 20 21:58:25 2012 +0000" }, "message": "FS-Cache: Make cookie relinquishment wait for outstanding reads\n\nMake fscache_relinquish_cookie() log a warning and wait if there are any\noutstanding reads left on the cookie it was given.\n\nSigned-off-by: David Howells \u003cdhowells@redhat.com\u003e\n" }, { "commit": "a13eea6bd9ee62ceacfc5243d54c84396bc86cb4", "tree": "46192468880c144f2b367deb5188267866ee1fac", "parents": [ "fcc16882ac4532aaa644bff444f0c5d6228ba71e", "6666e6aa9f36b2bfd6b30072c07b34f2a24becf1" ], "author": { "name": "Linus Torvalds", "email": "torvalds@linux-foundation.org", "time": "Thu Dec 20 13:54:51 2012 -0800" }, "committer": { "name": "Linus Torvalds", "email": "torvalds@linux-foundation.org", "time": "Thu Dec 20 13:54:52 2012 -0800" }, "message": "Merge tag \u0027for-3.8-merge\u0027 of git://git.kernel.org/pub/scm/linux/kernel/git/jaegeuk/f2fs\n\nPull new F2FS filesystem from Jaegeuk Kim:\n \"Introduce a new file system, Flash-Friendly File System (F2FS), to\n Linux 3.8.\n\n Highlights:\n - Add initial f2fs source codes\n - Fix an endian conversion bug\n - Fix build failures on random configs\n - Fix the power-off-recovery routine\n - Minor cleanup, coding style, and typos patches\"\n\nFrom the Kconfig help text:\n\n F2FS is based on Log-structured File System (LFS), which supports\n versatile \"flash-friendly\" features.
