The other ptrace checks within\nproc for elements like environ, maps, and fds are changed to pass the\nread mode instead of attach.\n\nIn the SELinux case, we model such reading of process state as a\nreading of a proc file labeled with the target process\u0027 label. This\nenables SELinux policy to permit such reading of process state without\npermitting control or manipulation of the target process, as there are\na number of cases where programs probe for such information via proc\nbut do not need to be able to control the target (e.g. procps,\nlsof, PolicyKit, ConsoleKit). At present we have to choose between\nallowing full ptrace in policy (more permissive than required/desired)\nor breaking functionality (or in some cases just silencing the denials\nvia dontaudit rules but this can hide genuine attacks).\n\nThis version of the patch incorporates comments from Casey Schaufler\n(change/replace existing ptrace_may_attach interface, pass access\nmode), and Chris Wright (provide greater consistency in the checking).\n\nNote that like their predecessors __ptrace_may_attach and\nptrace_may_attach, the __ptrace_may_access and ptrace_may_access\ninterfaces use different return value conventions from each other (0\nor -errno vs. 1 or 0). I retained this difference to avoid any\nchanges to the caller logic but made the difference clearer by\nchanging the latter interface to return a bool rather than an int and\nby adding a comment about it to ptrace.h for any future callers.\n\nSigned-off-by: Stephen Smalley \u003csds@tycho.nsa.gov\u003e\nAcked-by: Chris Wright \u003cchrisw@sous-sol.org\u003e\nSigned-off-by: James Morris \u003cjmorris@namei.org\u003e\n" }, { "commit": "aed5417593ad125283f35513573282139a8664b5", "tree": "8e9ba5f4d81ef3c8e8de0e0d7d6d1acaa79041f2", "parents": [ "aabe188565124ee2ed060a072764d6ed34dfa4ed" ], "author": { "name": "Vegard Nossum", "email": "vegard.nossum@gmail.com", "time": "Thu Jun 05 22:46:53 2008 -0700" }, "committer": { "name": "Linus Torvalds", "email": "torvalds@linux-foundation.org", "time": "Fri Jun 06 11:29:13 2008 -0700" }, "message": "proc: calculate the correct /proc/\u003cpid\u003e link count\n\nThis patch:\n\n commit e9720acd728a46cb40daa52c99a979f7c4ff195c\n Author: Pavel Emelyanov \u003cxemul@openvz.org\u003e\n Date: Fri Mar 7 11:08:40 2008 -0800\n\n [NET]: Make /proc/net a symlink on /proc/self/net (v3)\n\nintroduced a /proc/self/net directory without bumping the corresponding\nlink count for /proc/self.\n\nThis patch replaces the static link count initializations with a call that\ncounts the number of directory entries in the given pid_entry table\nwhenever it is instantiated, and thus relieves the burden of manually\nkeeping the two in sync.\n\n[akpm@linux-foundation.org: cleanup]\nAcked-by: Eric W.

With a debug\npatch adding proper reverse links and stack trace logging in ext3 deployed\nin production, I found journal_stop is never run because\nmark_inode_dirty_sync is called inside release_task called by do_exit.\n(that was quite fun because I would have never thought about this\nsubtleness, I thought a regular path in ext3 had a bug and it forgot to\ncall journal_stop)\n\ndo_exit-\u003erelease_task-\u003emark_inode_dirty_sync-\u003eschedule() (will never\ncome back to run journal_stop)\n\nThe reason is that shrink_dcache_parent is racy by design (feature not\na bug) and it can do blocking I/O in some case, but the point is that\ncalling shrink_dcache_parent at the last stage of do_exit isn\u0027t safe\nfor self-reaping tasks.\n\nI guess the memory pressure of the unbalanced highmem system allowed\nto trigger this more easily.\n\nNow mainline doesn\u0027t have this line in iput (like sles9 has):\n\n \t if (inode-\u003ei_state \u0026 I_DIRTY_DELAYED)\n\t \t\t\tmark_inode_dirty_sync(inode);\n\nso it will probably not crash with ext3, but for example ext2 implements an\nI/O-blocking ext2_put_inode that will lead to similar screwups with\next2_free_blocks never coming back and it\u0027s definitely wrong to call\nblocking-IO paths inside do_exit. So this should fix a subtle bug in\nmainline too (not verified in practice though). The equivalent fix for\next3 is also not verified yet to fix the problem in sles9 but I don\u0027t have\ndoubt it will (it usually takes days to crash, so it\u0027ll take weeks to be\nsure).\n\nAn alternate fix would be to offload that work to a kernel thread, but I\ndon\u0027t think a reschedule for this is worth it, the vm should be able to\ncollect those entries for the synchronous release_task.\n\nSigned-off-by: Andrea Arcangeli \u003candrea@suse.de\u003e\nCc: Jan Kara \u003cjack@ucw.cz\u003e\nCc: Ingo Molnar \u003cmingo@elte.hu\u003e\nCc: \"Eric W.
