The final call to fscache_put_operation() can then check that an op\n in the appropriate state (complete or cancelled).\n\n (3) Adjust the use of object-\u003en_ops, -\u003en_in_progress, -\u003en_exclusive to better\n govern the state of an object:\n\n\t(a) The -\u003en_ops is now the number of extant operations on the object\n\t and is now decremented by fscache_put_operation() only.\n\n\t(b) The -\u003en_in_progress is simply the number of objects that have been\n\t taken off of the object\u0027s pending queue for the purposes of being\n\t run. This is decremented by fscache_op_complete() only.\n\n\t(c) The -\u003en_exclusive is the number of exclusive ops that have been\n\t submitted and queued or are in progress. It is decremented by\n\t fscache_op_complete() and by fscache_cancel_op().\n\n fscache_put_operation() and fscache_operation_gc() now no longer try to\n clean up -\u003en_exclusive and -\u003en_in_progress. That was leading to double\n decrements against fscache_cancel_op().\n\n fscache_cancel_op() now no longer decrements -\u003en_ops. That was leading to\n double decrements against fscache_put_operation().\n\n fscache_submit_exclusive_op() now decides whether it has to queue an op\n based on -\u003en_in_progress being \u003e 0 rather than -\u003en_ops \u003e 0 as the latter\n will persist in being true even after all preceding operations have been\n cancelled or completed. Furthermore, if an object is active and there are\n runnable ops against it, there must be at least one op running.\n\n (4) Add a remaining-pages counter (n_pages) to struct fscache_retrieval and\n provide a function to record completion of the pages as they complete.\n\n When n_pages reaches 0, the operation is deemed to be complete and\n fscache_op_complete() is called.\n\n Add calls to fscache_retrieval_complete() anywhere we\u0027ve finished with a\n page we\u0027ve been given to read or allocate for. 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": "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.

No client that we\u0027re aware of has\never done this, but in theory it could be useful.\n\nThe source of the limitation: we need an array of iovecs to pass to the\nwrite operation. In the worst case that array of iovecs could have\nhundreds of elements (the maximum rwsize divided by the page size), so\nit\u0027s too big to put on the stack, or in each compound op.

This effectively ensures\nthat the underlying blocks are allocated and avoids the need for the swap\nsubsystem to locate what physical blocks store offsets within a file.\n\nIf the swap subsystem is to use the filesystem information to locate the\nblocks, it is critical that information such as block groups, block\nbitmaps and the block descriptor table that map the swap file were\nresident in memory. This patch adds address_space_operations that the VM\ncan call when activating or deactivating swap backed by a file.\n\n int swap_activate(struct file *);\n int swap_deactivate(struct file *);\n\nThe -\u003eswap_activate() method is used to communicate to the file that the\nVM relies on it, and the address_space should take adequate measures such\nas reserving space in the underlying device, reserving memory for mempools\nand pinning information such as the block descriptor table in memory. The\n-\u003eswap_deactivate() method is called on sys_swapoff() if -\u003eswap_activate()\nreturned success.\n\nAfter a successful swapfile -\u003eswap_activate, the swapfile is marked\nSWP_FILE and swapper_space.a_ops will proxy to\nsis-\u003eswap_file-\u003ef_mappings-\u003ea_ops using -\u003edirect_io to write swapcache\npages and -\u003ereadpage to read.\n\nIt is perfectly possible that direct_IO be used to read the swap pages but\nit is an unnecessary complication. Similarly, it is possible that\n-\u003ewritepage be used instead of direct_io to write the pages but filesystem\ndevelopers have stated that calling writepage from the VM is undesirable\nfor a variety of reasons and using direct_IO opens up the possibility of\nwriting back batches of swap pages in the future.\n\n[a.p.zijlstra@chello.nl: Original patch]\nSigned-off-by: Mel Gorman \u003cmgorman@suse.de\u003e\nAcked-by: Rik van Riel \u003criel@redhat.com\u003e\nCc: Christoph Hellwig \u003chch@infradead.org\u003e\nCc: David S.

An IP address:port combination\n2. A string URI which is constructed as a URL with a protocol prefix\n followed by :// and a string as address. For each protocol prefix\n the string-address format might be different.\n\nWe only support the second option. The first option is just redundant\nto the second one.\nNOTE: The Kernel part of autologin does not parse the URI string. It\njust channels it to a user-mode script. So any new login protocols should\nonly update the user-mode script which is a part of the nfs-utils package,\nbut the Kernel need not change.\n\nWe implement the autologin by using the call_usermodehelper() API.\n(Thanks to Steve Dickson \u003csteved@redhat.com\u003e for pointing it out)\nSo there is no running daemon needed, and/or special setup.\n\nWe Add the osd_login_prog Kernel module parameters which defaults to:\n\t/sbin/osd_login\n\nKernel try\u0027s to upcall the program specified in osd_login_prog.

The default backward-compatible \"relaxed\" behaviour is left\nuntouched.\n\nThe first mount option is called \"hidepid\" and its value defines how much\ninfo about processes we want to be available for non-owners:\n\nhidepid\u003d0 (default) means the old behavior - anybody may read all\nworld-readable /proc/PID/* files.\n\nhidepid\u003d1 means users may not access any /proc/\u003cpid\u003e/ directories, but\ntheir own. Sensitive files like cmdline, sched*, status are now protected\nagainst other users. As permission checking done in proc_pid_permission()\nand files\u0027 permissions are left untouched, programs expecting specific\nfiles\u0027 modes are not confused.\n\nhidepid\u003d2 means hidepid\u003d1 plus all /proc/PID/ will be invisible to other\nusers. It doesn\u0027t mean that it hides whether a process exists (it can be\nlearned by other means, e.g. by kill -0 $PID), but it hides process\u0027 euid\nand egid. It compicates intruder\u0027s task of gathering info about running\nprocesses, whether some daemon runs with elevated privileges, whether\nanother user runs some sensitive program, whether other users run any\nprogram at all, etc.\n\ngid\u003dXXX defines a group that will be able to gather all processes\u0027 info\n(as in hidepid\u003d0 mode). This group should be used instead of putting\nnonroot user in sudoers file or something. However, untrusted users (like\ndaemons, etc.) which are not supposed to monitor the tasks in the whole\nsystem should not be added to the group.\n\nhidepid\u003d1 or higher is designed to restrict access to procfs files, which\nmight reveal some sensitive private information like precise keystrokes\ntimings:\n\nhttp://www.openwall.com/lists/oss-security/2011/11/05/3\n\nhidepid\u003d1/2 doesn\u0027t break monitoring userspace tools. ps, top, pgrep, and\nconky gracefully handle EPERM/ENOENT and behave as if the current user is\nthe only user running processes. pstree shows the process subtree which\ncontains \"pstree\" process.\n\nNote: the patch doesn\u0027t deal with setuid/setgid issues of keeping\npreopened descriptors of procfs files (like\nhttps://lkml.org/lkml/2011/2/7/368). We rely on that the leaked\ninformation like the scheduling counters of setuid apps doesn\u0027t threaten\nanybody\u0027s privacy - only the user started the setuid program may read the\ncounters.\n\nSigned-off-by: Vasiliy Kulikov \u003csegoon@openwall.com\u003e\nCc: Alexey Dobriyan \u003cadobriyan@gmail.com\u003e\nCc: Al Viro \u003cviro@zeniv.linux.org.uk\u003e\nCc: Randy Dunlap \u003crdunlap@xenotime.net\u003e\nCc: \"H.
