Independent processes\naccessing the same file synchronize over a single lock, even though\nthey have no need for synchronization at all.\n\nUnder high utilization this can cause llseek to scale very poorly on larger\nsystems.\n\nThis patch does some rethinking of the llseek locking model:\n\nFirst the 64bit f_pos is not necessarily atomic without locks\non 32bit systems. This can already cause races with read() today.\nThis was discussed on linux-kernel in the past and deemed acceptable.\nThe patch does not change that.\n\nLet\u0027s look at the different seek variants:\n\nSEEK_SET: Doesn\u0027t really need any locking.\nIf there\u0027s a race one writer wins, the other loses.\n\nFor 32bit the non atomic update races against read()\nstay the same. Without a lock they can also happen\nagainst write() now. The read() race was deemed\nacceptable in past discussions, and I think if it\u0027s\nok for read it\u0027s ok for write too.\n\n\u003d\u003e Don\u0027t need a lock.\n\nSEEK_END: This behaves like SEEK_SET plus it reads\nthe maximum size too. Reading the maximum size would have the\n32bit atomic problem. But luckily we already have a way to read\nthe maximum size without locking (i_size_read), so we\ncan just use that instead.\n\nWithout i_mutex there is no synchronization with write() anymore,\nhowever since the write() update is atomic on 64bit it just behaves\nlike another racy SEEK_SET. On non atomic 32bit it\u0027s the same\nas SEEK_SET.\n\n\u003d\u003e Don\u0027t need a lock, but need to use i_size_read()\n\nSEEK_CUR: This has a read-modify-write race window\non the same file. One could argue that any application\ndoing unsynchronized seeks on the same file is already broken.\nBut for the sake of not adding a regression here I\u0027m\nusing the file-\u003ef_lock to synchronize this. Using this\nlock is much better than the inode mutex because it doesn\u0027t\nsynchronize between processes.\n\n\u003d\u003e So still need a lock, but can use a f_lock.\n\nThis patch implements this new scheme in generic_file_llseek.\nI dropped generic_file_llseek_unlocked and changed all callers.\n\nSigned-off-by: Andi Kleen \u003cak@linux.intel.com\u003e\nSigned-off-by: Christoph Hellwig \u003chch@lst.de\u003e\n" }, { "commit": "36b8d186e6cc8e32cb5227f5645a58e1bc0af190", "tree": "1000ad26e189e6ff2c53fb7eeff605f59c7ad94e", "parents": [ "cd85b557414fe4cd44ea6608825e96612a5fe2b2", "c45ed235abf1b0b6666417e3c394f18717976acd" ], "author": { "name": "Linus Torvalds", "email": "torvalds@linux-foundation.org", "time": "Tue Oct 25 09:45:31 2011 +0200" }, "committer": { "name": "Linus Torvalds", "email": "torvalds@linux-foundation.org", "time": "Tue Oct 25 09:45:31 2011 +0200" }, "message": "Merge branch \u0027next\u0027 of git://selinuxproject.org/~jmorris/linux-security\n\n* \u0027next\u0027 of git://selinuxproject.org/~jmorris/linux-security: (95 commits)\n TOMOYO: Fix incomplete read after seek.\n Smack: allow to access /smack/access as normal user\n TOMOYO: Fix unused kernel config option.\n Smack: fix: invalid length set for the result of /smack/access\n Smack: compilation fix\n Smack: fix for /smack/access output, use string instead of byte\n Smack: domain transition protections (v3)\n Smack: Provide information for UDS getsockopt(SO_PEERCRED)\n Smack: Clean up comments\n Smack: Repair processing of fcntl\n Smack: Rule list lookup performance\n Smack: check permissions from user space (v2)\n TOMOYO: Fix quota and garbage collector.\n TOMOYO: Remove redundant tasklist_lock.\n TOMOYO: Fix domain transition failure warning.\n TOMOYO: Remove tomoyo_policy_memory_lock spinlock.\n TOMOYO: Simplify garbage collector.\n TOMOYO: Fix make namespacecheck warnings.\n target: check hex2bin result\n encrypted-keys: check hex2bin result\n ...\n" }, { "commit": "b99b98dc2673a123a73068f16720232d7be7e669", "tree": "a191b03e9c054c62777d1b3ab3cae55cbd6e5e01", "parents": [ "9ae32429fe036fcfce036ec57b28fc59f3911976" ], "author": { "name": "Steven Whitehouse", "email": "swhiteho@redhat.com", "time": "Wed Sep 21 11:05:16 2011 +0100" }, "committer": { "name": "Steven Whitehouse", "email": "swhiteho@redhat.com", "time": "Fri Oct 21 12:39:54 2011 +0100" }, "message": "GFS2: Move readahead of metadata during deallocation into its own function\n\nMove the recently added readahead of the indirect pointer\ntree during deallocation into its own function in order\nthat we can use it elsewhere in the future.

The metadata\nblocks were journaled and also the rgrp itself was added to a list. The reason\nfor adding the rgrp to the list in the journal was so that the \"repolish\nclones\" code could be run to update the free space, and potentially send any\ndiscard requests when the log was flushed. This was done by comparing the\n\"cloned\" bitmap with what had been written back on disk during the transaction\ncommit.\n\nDue to this, there was a requirement to hang on to the rgrps\u0027 bitmap buffers\nuntil the journal had been flushed. For that reason, there was a rather\ncomplicated set up in the -\u003ego_lock -\u003ego_unlock functions for rgrps involving\nboth a mutex and a spinlock (the -\u003esd_rindex_spin) to maintain a reference\ncount on the buffers.\n\nHowever, the journal maintains a reference count on the buffers anyway, since\nthey are being journaled as metadata buffers. So by moving the code which deals\nwith the post-journal accounting for bitmap blocks to the metadata journaling\ncode, we can entirely dispense with the rather strange buffer ref counting\nscheme and also the requirement to journal the rgrps.\n\nThe net result of all this is that the -\u003esd_rindex_spin is left to do exactly\none job, and that is to look after the rbtree or rgrps.\n\nThis patch is designed to be a stepping stone towards using RCU for the rbtree\nof resource groups, however the reduction in the number of uses of the\n-\u003esd_rindex_spin is likely to have benefits for multi-threaded workloads,\nanyway.\n\nThe patch retains -\u003ego_lock and -\u003ego_unlock for rgrps, however these maybe also\nbe removed in future in favour of calling the functions directly where required\nin the code. That will allow locking of resource groups without needing to\nactually read them in - something that could be useful in speeding up statfs.\n\nIn the mean time though it is valid to dereference -\u003ebi_bh only when the rgrp\nis locked. This is basically the same rule as before, modulo the references not\nbeing valid until the following journal flush.\n\nSigned-off-by: Steven Whitehouse \u003cswhiteho@redhat.com\u003e\nSigned-off-by: Bob Peterson \u003crpeterso@redhat.com\u003e\nCc: Benjamin Marzinski \u003cbmarzins@redhat.com\u003e\n" }, { "commit": "9453615a1a7ef3fa910c6464a619595556cfcd63", "tree": "40242c84367376197420ce12e50ae29e720dc5e3", "parents": [ "9a63edd12ba3c18351f00d6b77a6b2f49f2b8eb6" ], "author": { "name": "Steven Whitehouse", "email": "swhiteho@redhat.com", "time": "Tue Aug 23 10:19:25 2011 +0100" }, "committer": { "name": "Steven Whitehouse", "email": "swhiteho@redhat.com", "time": "Fri Oct 21 12:39:29 2011 +0100" }, "message": "GFS2: Fix lseek after SEEK_DATA, SEEK_HOLE have been added\n\nWe need to take the inode\u0027s glock whenever the inode\u0027s size\nis referenced, otherwise it might not be uptodate.

The lock thats added into gfs2_releasepage() may\npossibly be a candidate for replacing with RCU at some future\npoint, but at this stage we\u0027ve gone for the obvious fix.\n\nThe second issue is that gfs2_write_inode() can end up calling\na glock recursively when called from gfs2_evict_inode() via the\nsyncing code, so it needs a guard added.\n\nThe third issue is that we either need to not truncate the metadata\npages of inodes which have zero link count, but which we cannot\ndeallocate due to them still being in use by other nodes, or we need\nto ensure that those pages have all made it through the journal and\nail lists first. This patch takes the former approach, but the\nlatter has also been tested and there is nothing to choose between\nthem performance-wise.
