For more information on how to use this\npatch, Chris Friedhoff has posted a nice page at\nhttp://www.friedhoff.org/fscaps.html.\n\nChangelog:\n\tNov 27:\n\tIncorporate fixes from Andrew Morton\n\t(security-introduce-file-caps-tweaks and\n\tsecurity-introduce-file-caps-warning-fix)\n\tFix Kconfig dependency.\n\tFix change signaling behavior when file caps are not compiled in.\n\n\tNov 13:\n\tIntegrate comments from Alexey: Remove CONFIG_ ifdef from\n\tcapability.h, and use %zd for printing a size_t.\n\n\tNov 13:\n\tFix endianness warnings by sparse as suggested by Alexey\n\tDobriyan.\n\n\tNov 09:\n\tAddress warnings of unused variables at cap_bprm_set_security\n\twhen file capabilities are disabled, and simultaneously clean\n\tup the code a little, by pulling the new code into a helper\n\tfunction.\n\n\tNov 08:\n\tFor pointers to required userspace tools and how to use\n\tthem, see http://www.friedhoff.org/fscaps.html.\n\n\tNov 07:\n\tFix the calculation of the highest bit checked in\n\tcheck_cap_sanity().\n\n\tNov 07:\n\tAllow file caps to be enabled without CONFIG_SECURITY, since\n\tcapabilities are the default.\n\tHook cap_task_setscheduler when !CONFIG_SECURITY.\n\tMove capable(TASK_KILL) to end of cap_task_kill to reduce\n\taudit messages.\n\n\tNov 05:\n\tAdd secondary calls in selinux/hooks.c to task_setioprio and\n\ttask_setscheduler so that selinux and capabilities with file\n\tcap support can be stacked.\n\n\tSep 05:\n\tAs Seth Arnold points out, uid checks are out of place\n\tfor capability code.\n\n\tSep 01:\n\tDefine task_setscheduler, task_setioprio, cap_task_kill, and\n\ttask_setnice to make sure a user cannot affect a process in which\n\tthey called a program with some fscaps.\n\n\tOne remaining question is the note under task_setscheduler: are we\n\tok with CAP_SYS_NICE being sufficient to confine a process to a\n\tcpuset?\n\n\tIt is a semantic change, as without fsccaps, attach_task doesn\u0027t\n\tallow CAP_SYS_NICE to override the uid equivalence check.  But since\n\tit uses security_task_setscheduler, which elsewhere is used where\n\tCAP_SYS_NICE can be used to override the uid equivalence check,\n\tfixing it might be tough.\n\n\t     task_setscheduler\n\t\t note: this also controls cpuset:attach_task.  Are we ok with\n\t\t     CAP_SYS_NICE being used to confine to a cpuset?\n\t     task_setioprio\n\t     task_setnice\n\t\t sys_setpriority uses this (through set_one_prio) for another\n\t\t process.

If there is\nanother inode with a small number of dirty pages, we hit a case where the loop\niteration in wb_kupdate() terminates prematurely because wbc.nr_to_write \u003e 0.\nThus leaving the inode that has large amount of dirty pages behind and it has\nto wait for another dirty_writeback_interval before we flush it again.  We\neffectively only write out MAX_WRITEBACK_PAGES every dirty_writeback_interval.\nIf the rate of dirtying is sufficiently high, the system will start\naccumulate a large number of dirty pages.\n\nSo fix it by having another sb-\u003es_more_io list on which to park the inode\nwhile we iterate through sb-\u003es_io and to allow each dirty inode which resides\non that sb to have an equal chance of flushing some amount of dirty pages.\n\nSigned-off-by: Ken Chen \u003ckenchen@google.com\u003e\nSigned-off-by: Andrew Morton \u003cakpm@linux-foundation.org\u003e\nSigned-off-by: Linus Torvalds \u003ctorvalds@linux-foundation.org\u003e\n"

With preallocation, applications\nalso get a guarantee of space for particular file(s) - even if later the\nthe system becomes full.\n\nCurrently, glibc provides an interface called posix_fallocate() which\ncan be used for similar cause. Though this has the advantage of working\non all file systems, but it is quite slow (since it writes zeroes to\neach block that has to be preallocated). Without a doubt, file systems\ncan do this more efficiently within the kernel, by implementing\nthe proposed fallocate() system call. It is expected that\nposix_fallocate() will be modified to call this new system call first\nand incase the kernel/filesystem does not implement it, it should fall\nback to the current implementation of writing zeroes to the new blocks.\nToDos:\n1. Implementation on other architectures (other than i386, x86_64,\n   and ppc). Patches for s390(x) and ia64 are already available from\n   previous posts, but it was decided that they should be added later\n   once fallocate is in the mainline.

      "message": "add filesystem subtype support\n\nThere\u0027s a slight problem with filesystem type representation in fuse\nbased filesystems.\n\nFrom the kernel\u0027s view, there are just two filesystem types: fuse and\nfuseblk.  From the user\u0027s view there are lots of different filesystem\ntypes.  The user is not even much concerned if the filesystem is fuse based\nor not.  So there\u0027s a conflict of interest in how this should be\nrepresented in fstab, mtab and /proc/mounts.\n\nThe current scheme is to encode the real filesystem type in the mount\nsource.  So an sshfs mount looks like this:\n\n  sshfs#user@server:/   /mnt/server    fuse   rw,nosuid,nodev,...\n\nThis url-ish syntax works OK for sshfs and similar filesystems.  However\nfor block device based filesystems (ntfs-3g, zfs) it doesn\u0027t work, since\nthe kernel expects the mount source to be a real device name.\n\nA possibly better scheme would be to encode the real type in the type\nfield as \"type.subtype\".  So fuse mounts would look like this:\n\n  /dev/hda1       /mnt/windows   fuseblk.ntfs-3g   rw,...\n  user@server:/   /mnt/server    fuse.sshfs        rw,nosuid,nodev,...\n\nThis patch adds the necessary code to the kernel so that this can be\ncorrectly displayed in /proc/mounts.\n\nSigned-off-by: Miklos Szeredi \u003cmszeredi@suse.cz\u003e\nSigned-off-by: Andrew Morton \u003cakpm@linux-foundation.org\u003e\nSigned-off-by: Linus Torvalds \u003ctorvalds@linux-foundation.org\u003e\n"

So while\nfl_notify is merely a hint to the caller that it should retry, fl_grant\nactually communicates the final result of the lock operation (with the\nlock already acquired in the succesful case).\n\nTherefore fl_grant takes a lock, a status and, for the test lock case, a\nconflicting lock.  We also allow fl_grant to return an error to the\nfilesystem, to handle the case where the fl_grant requests arrives after\nthe lock manager has already given up waiting for it.\n\nSigned-off-by: Marc Eshel \u003ceshel@almaden.ibm.com\u003e\nSigned-off-by: J.

      "message": "[PATCH] VFS: Make filldir_t and struct kstat deal in 64-bit inode numbers\n\nThese patches make the kernel pass 64-bit inode numbers internally when\ncommunicating to userspace, even on a 32-bit system.  They are required\nbecause some filesystems have intrinsic 64-bit inode numbers: NFS3+ and XFS\nfor example.  The 64-bit inode numbers are then propagated to userspace\nautomatically where the arch supports it.\n\nProblems have been seen with userspace (eg: ld.so) using the 64-bit inode\nnumber returned by stat64() or getdents64() to differentiate files, and\nfailing because the 64-bit inode number space was compressed to 32-bits, and\nso overlaps occur.\n\nThis patch:\n\nMake filldir_t take a 64-bit inode number and struct kstat carry a 64-bit\ninode number so that 64-bit inode numbers can be passed back to userspace.\n\nThe stat functions then returns the full 64-bit inode number where\navailable and where possible.  If it is not possible to represent the inode\nnumber supplied by the filesystem in the field provided by userspace, then\nerror EOVERFLOW will be issued.\n\nSimilarly, the getdents/readdir functions now pass the full 64-bit inode\nnumber to userspace where possible, returning EOVERFLOW instead when a\ndirectory entry is encountered that can\u0027t be properly represented.\n\nNote that this means that some inodes will not be stat\u0027able on a 32-bit\nsystem with old libraries where they were before - but it does mean that\nthere will be no ambiguity over what a 32-bit inode number refers to.\n\nNote similarly that directory scans may be cut short with an error on a\n32-bit system with old libraries where the scan would work before for the\nsame reasons.\n\nIt is judged unlikely that this situation will occur because modern glibc\nuses 64-bit capable versions of stat and getdents class functions\nexclusively, and that older systems are unlikely to encounter\nunrepresentable inode numbers anyway.\n\n[akpm: alpha build fix]\nSigned-off-by: David Howells \u003cdhowells@redhat.com\u003e\nCc: Trond Myklebust \u003ctrond.myklebust@fys.uio.no\u003e\nCc: Al Viro \u003cviro@zeniv.linux.org.uk\u003e\nSigned-off-by: Andrew Morton \u003cakpm@osdl.org\u003e\nSigned-off-by: Linus Torvalds \u003ctorvalds@osdl.org\u003e\n"

      "message": "[PATCH] BLOCK: Make it possible to disable the block layer [try #6]\n\nMake it possible to disable the block layer.  Not all embedded devices require\nit, some can make do with just JFFS2, NFS, ramfs, etc - none of which require\nthe block layer to be present.\n\nThis patch does the following:\n\n (*) Introduces CONFIG_BLOCK to disable the block layer, buffering and blockdev\n     support.\n\n (*) Adds dependencies on CONFIG_BLOCK to any configuration item that controls\n     an item that uses the block layer.  This includes:\n\n     (*) Block I/O tracing.\n\n     (*) Disk partition code.\n\n     (*) All filesystems that are block based, eg: Ext3, ReiserFS, ISOFS.\n\n     (*) The SCSI layer.  As far as I can tell, even SCSI chardevs use the\n     \t block layer to do scheduling.  Some drivers that use SCSI facilities -\n     \t such as USB storage - end up disabled indirectly from this.\n\n     (*) Various block-based device drivers, such as IDE and the old CDROM\n     \t drivers.\n\n     (*) MTD blockdev handling and FTL.\n\n     (*) JFFS - which uses set_bdev_super(), something it could avoid doing by\n     \t taking a leaf out of JFFS2\u0027s book.\n\n (*) Makes most of the contents of linux/blkdev.h, linux/buffer_head.h and\n     linux/elevator.h contingent on CONFIG_BLOCK being set.  sector_div() is,\n     however, still used in places, and so is still available.\n\n (*) Also made contingent are the contents of linux/mpage.h, linux/genhd.h and\n     parts of linux/fs.h.\n\n (*) Makes a number of files in fs/ contingent on CONFIG_BLOCK.\n\n (*) Makes mm/bounce.c (bounce buffering) contingent on CONFIG_BLOCK.\n\n (*) set_page_dirty() doesn\u0027t call __set_page_dirty_buffers() if CONFIG_BLOCK\n     is not enabled.\n\n (*) fs/no-block.c is created to hold out-of-line stubs and things that are\n     required when CONFIG_BLOCK is not set:\n\n     (*) Default blockdev file operations (to give error ENODEV on opening).\n\n (*) Makes some /proc changes:\n\n     (*) /proc/devices does not list any blockdevs.\n\n     (*) /proc/diskstats and /proc/partitions are contingent on CONFIG_BLOCK.\n\n (*) Makes some compat ioctl handling contingent on CONFIG_BLOCK.\n\n (*) If CONFIG_BLOCK is not defined, makes sys_quotactl() return -ENODEV if\n     given command other than Q_SYNC or if a special device is specified.\n\n (*) In init/do_mounts.c, no reference is made to the blockdev routines if\n     CONFIG_BLOCK is not defined.  This does not prohibit NFS roots or JFFS2.\n\n (*) The bdflush, ioprio_set and ioprio_get syscalls can now be absent (return\n     error ENOSYS by way of cond_syscall if so).\n\n (*) The seclvl_bd_claim() and seclvl_bd_release() security calls do nothing if\n     CONFIG_BLOCK is not set, since they can\u0027t then happen.\n\nSigned-Off-By: David Howells \u003cdhowells@redhat.com\u003e\nSigned-off-by: Jens Axboe \u003caxboe@kernel.dk\u003e\n"
