This allows programs to be given a\nsubset of root\u0027s powers regardless of who runs them, without having to use\nsetuid and giving the binary all of root\u0027s powers.\n\nThis version works with Kaigai Kohei\u0027s userspace tools, found at\nhttp://www.kaigai.gr.jp/index.php.  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.  Need same checks as setrlimit\n\n\tAug 21:\n\tUpdated secureexec implementation to reflect the fact that\n\teuid and uid might be the same and nonzero, but the process\n\tmight still have elevated caps.\n\n\tAug 15:\n\tHandle endianness of xattrs.\n\tEnforce capability version match between kernel and disk.\n\tEnforce that no bits beyond the known max capability are\n\tset, else return -EPERM.\n\tWith this extra processing, it may be worth reconsidering\n\tdoing all the work at bprm_set_security rather than\n\td_instantiate.\n\n\tAug 10:\n\tAlways call getxattr at bprm_set_security, rather than\n\tcaching it at d_instantiate.\n\n[morgan@kernel.org: file-caps clean up for linux/capability.h]\n[bunk@kernel.org: unexport cap_inode_killpriv]\nSigned-off-by: Serge E.

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. Hence not including those patches\n   in this take.\n2.

Those customers that use xip on s390 are not\nusing sendfile() as far as we know, and so far s390 is the only platform\nthis could potentially be used on so far.\nHaving sendfile is not a popular feature for execute in place file\nsystems, however we have a working implementation of splice_read() based\non fs/splice.c if anyone asks for it.\nAt this point in time, it does not seem preferable to merge\nsplice_read() for xip because it causes extra maintenence effort due to\ncode duplication and it requires struct page behind the xip memory\nsegment.

      "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"

      "message": "locks: add fl_grant callback for asynchronous lock return\n\nAcquiring a lock on a cluster filesystem may require communication with\nremote hosts, and to avoid blocking lockd or nfsd threads during such\ncommunication, we allow the results to be returned asynchronously.\n\nWhen a -\u003elock() call needs to block, the file system will return\n-EINPROGRESS, and then later return the results with a call to the\nroutine in the fl_grant field of the lock_manager_operations struct.\n\nThis differs from the case when -\u003elock returns -EAGAIN to a blocking\nlock request; in that case, the filesystem calls fl_notify when the lock\nis granted, and the caller retries the original lock.  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.
