POSIX says this in the spec for chown():\n\n \"If the specified file is a regular file, one or more of the\n S_IXUSR, S_IXGRP, or S_IXOTH bits of the file mode are set, and the\n process does not have appropriate privileges, the set-user-ID\n (S_ISUID) and set-group-ID (S_ISGID) bits of the file mode shall\n be cleared upon successful return from chown().\"\n\nIf I\u0027m reading this correctly, then knfsd is doing this wrong. It should\nbe clearing both the setuid and setgid bit on any SETATTR that changes\nthe uid or gid. This wasn\u0027t really as noticable before, but now that the\nATTR_KILL_S*ID bits are a no-op for the NFS client, it\u0027s more evident.\n\nThis patch corrects the nfsd_setattr logic so that this occurs. It also\ndoes a bit of cleanup to the function.\n\nThere is also one small behavioral change. If a SETATTR call comes in\nthat changes the uid/gid and the mode, then we now only clear the setgid\nbit if the group execute bit isn\u0027t set. The setgid bit without a group\nexecute bit signifies mandatory locking and we likely don\u0027t want to\nclear the bit in that case. Since there is no call in POSIX that should\ngenerate a SETATTR call like this, then this should rarely happen, but\nit\u0027s worth noting.\n\nSigned-off-by: Jeff Layton \u003cjlayton@redhat.com\u003e\nSigned-off-by: J.

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.

Could you investigate whether it could use vfs_getxattr or if not\nadd a __vfs_getxattr helper to share the bits it is fine with?)\n\nFor NFSv4: instead of just converting it add an nfsd_getxattr helper for the\ncode shared by NFSv2/3 and NFSv4 ACLs. In fact that code isn\u0027t even\nNFS-specific, but I\u0027ll wait for more users to pop up first before moving it to\ncommon code.\n\nSigned-off-by: Christoph Hellwig \u003chch@lst.de\u003e\nAcked-by: Dave Kleikamp \u003cshaggy@austin.ibm.com\u003e\nSigned-off-by: Adrian Bunk \u003cbunk@stusta.de\u003e\nSigned-off-by: Neil Brown \u003cneilb@suse.de\u003e\nCc: Trond Myklebust \u003ctrond.myklebust@fys.uio.no\u003e\nSigned-off-by: Andrew Morton \u003cakpm@osdl.org\u003e\nSigned-off-by: Linus Torvalds \u003ctorvalds@osdl.org\u003e\n" }, { "commit": "1b1dcc1b57a49136f118a0f16367256ff9994a69", "tree": "b0b36d4f41d28c9d6514fb309d33c1a084d6309b", "parents": [ "794ee1baee1c26be40410233e6c20bceb2b03c08" ], "author": { "name": "Jes Sorensen", "email": "jes@sgi.com", "time": "Mon Jan 09 15:59:24 2006 -0800" }, "committer": { "name": "Ingo Molnar", "email": "mingo@hera.kernel.org", "time": "Mon Jan 09 15:59:24 2006 -0800" }, "message": "[PATCH] mutex subsystem, semaphore to mutex: VFS, -\u003ei_sem\n\nThis patch converts the inode semaphore to a mutex.
