      "message": "core dump: remain dumpable\n\nThe coredump code always calls set_dumpable(0) when it starts (even\nif RLIMIT_CORE prevents any core from being dumped).  The effect of\nthis (via task_dumpable) is to make /proc/pid/* files owned by root\ninstead of the user, so the user can no longer examine his own\nprocess--in a case where there was never any privileged data to\nprotect.  This affects e.g. auxv, environ, fd; in Fedora (execshield)\nkernels, also maps.  In practice, you can only notice this when a\ndebugger has requested PTRACE_EVENT_EXIT tracing.\n\nset_dumpable was only used in do_coredump for synchronization and not\nintended for any security purpose.  (It doesn\u0027t secure anything that wasn\u0027t\nalready unsecured when a process dies by SIGTERM instead of SIGQUIT.)\n\nThis changes do_coredump to check the core_waiters count as the means of\nsynchronization, which is sufficient.

      "message": "core_pattern: ignore RLIMIT_CORE if core_pattern is a pipe\n\nFor some time /proc/sys/kernel/core_pattern has been able to set its output\ndestination as a pipe, allowing a user space helper to receive and\nintellegently process a core.  This infrastructure however has some\nshortcommings which can be enhanced.  Specifically:\n\n1) The coredump code in the kernel should ignore RLIMIT_CORE limitation\n   when core_pattern is a pipe, since file system resources are not being\n   consumed in this case, unless the user application wishes to save the core,\n   at which point the app is restricted by usual file system limits and\n   restrictions.\n\n2) The core_pattern code should be able to parse and pass options to the\n   user space helper as an argv array.  The real core limit of the uid of the\n   crashing proces should also be passable to the user space helper (since it\n   is overridden to zero when called).\n\n3) Some miscellaneous bugs need to be cleaned up (specifically the\n   recognition of a recursive core dump, should the user mode helper itself\n   crash.  Also, the core dump code in the kernel should not wait for the user\n   mode helper to exit, since the same context is responsible for writing to\n   the pipe, and a read of the pipe by the user mode helper will result in a\n   deadlock.\n\nThis patch:\n\nRemove the check of RLIMIT_CORE if core_pattern is a pipe.  In the event that\ncore_pattern is a pipe, the entire core will be fed to the user mode helper.\n\nSigned-off-by: Neil Horman \u003cnhorman@tuxdriver.com\u003e\nCc: \u003cmartin.pitt@ubuntu.com\u003e\nCc: \u003cwwoods@redhat.com\u003e\nCc: Jeremy Fitzhardinge \u003cjeremy@goop.org\u003e\nSigned-off-by: Andrew Morton \u003cakpm@linux-foundation.org\u003e\nSigned-off-by: Linus Torvalds \u003ctorvalds@linux-foundation.org\u003e\n"

      "message": "signal/timer/event: signalfd core\n\nThis patch series implements the new signalfd() system call.\n\nI took part of the original Linus code (and you know how badly it can be\nbroken :), and I added even more breakage ;) Signals are fetched from the same\nsignal queue used by the process, so signalfd will compete with standard\nkernel delivery in dequeue_signal().  If you want to reliably fetch signals on\nthe signalfd file, you need to block them with sigprocmask(SIG_BLOCK).  This\nseems to be working fine on my Dual Opteron machine.  I made a quick test\nprogram for it:\n\nhttp://www.xmailserver.org/signafd-test.c\n\nThe signalfd() system call implements signal delivery into a file descriptor\nreceiver.  The signalfd file descriptor if created with the following API:\n\nint signalfd(int ufd, const sigset_t *mask, size_t masksize);\n\nThe \"ufd\" parameter allows to change an existing signalfd sigmask, w/out going\nto close/create cycle (Linus idea).  Use \"ufd\" \u003d\u003d -1 if you want a brand new\nsignalfd file.\n\nThe \"mask\" allows to specify the signal mask of signals that we are interested\nin.  The \"masksize\" parameter is the size of \"mask\".\n\nThe signalfd fd supports the poll(2) and read(2) system calls.  The poll(2)\nwill return POLLIN when signals are available to be dequeued.  As a direct\nconsequence of supporting the Linux poll subsystem, the signalfd fd can use\nused together with epoll(2) too.\n\nThe read(2) system call will return a \"struct signalfd_siginfo\" structure in\nthe userspace supplied buffer.  The return value is the number of bytes copied\nin the supplied buffer, or -1 in case of error.  The read(2) call can also\nreturn 0, in case the sighand structure to which the signalfd was attached,\nhas been orphaned.  The O_NONBLOCK flag is also supported, and read(2) will\nreturn -EAGAIN in case no signal is available.\n\nIf the size of the buffer passed to read(2) is lower than sizeof(struct\nsignalfd_siginfo), -EINVAL is returned.  A read from the signalfd can also\nreturn -ERESTARTSYS in case a signal hits the process.  The format of the\nstruct signalfd_siginfo is, and the valid fields depends of the (-\u003ecode \u0026\n__SI_MASK) value, in the same way a struct siginfo would:\n\nstruct signalfd_siginfo {\n\t__u32 signo;\t/* si_signo */\n\t__s32 err;\t/* si_errno */\n\t__s32 code;\t/* si_code */\n\t__u32 pid;\t/* si_pid */\n\t__u32 uid;\t/* si_uid */\n\t__s32 fd;\t/* si_fd */\n\t__u32 tid;\t/* si_fd */\n\t__u32 band;\t/* si_band */\n\t__u32 overrun;\t/* si_overrun */\n\t__u32 trapno;\t/* si_trapno */\n\t__s32 status;\t/* si_status */\n\t__s32 svint;\t/* si_int */\n\t__u64 svptr;\t/* si_ptr */\n\t__u64 utime;\t/* si_utime */\n\t__u64 stime;\t/* si_stime */\n\t__u64 addr;\t/* si_addr */\n};\n\n[akpm@linux-foundation.org: fix signalfd_copyinfo() on i386]\nSigned-off-by: Davide Libenzi \u003cdavidel@xmailserver.org\u003e\nSigned-off-by: Andrew Morton \u003cakpm@linux-foundation.org\u003e\nSigned-off-by: Linus Torvalds \u003ctorvalds@linux-foundation.org\u003e\n"

He writes:\n\n When a script is loaded, load_script() replaces argv[0] with the\n name of the interpreter and the filename passed to the exec syscall.\n However, there is no guarantee that the length of the interpreter\n name plus the length of the filename is greater than the length of\n the original argv[0]. If the difference happens to cross a page boundary,\n setup_arg_pages() will call put_dirty_page() [aka install_arg_page()]\n with an address outside the VMA.\n\n Therefore, remove_arg_zero() must free all pages which would be unused\n after the argument is removed.\n\nSo, rewrite the remove_arg_zero function without gotos, with a few comments,\nand with the commonly used explicit index/offset.

      "message": "[PATCH] Support piping into commands in /proc/sys/kernel/core_pattern\n\nUsing the infrastructure created in previous patches implement support to\npipe core dumps into programs.\n\nThis is done by overloading the existing core_pattern sysctl\nwith a new syntax:\n\n|program\n\nWhen the first character of the pattern is a \u0027|\u0027 the kernel will instead\nthreat the rest of the pattern as a command to run.  The core dump will be\nwritten to the standard input of that program instead of to a file.\n\nThis is useful for having automatic core dump analysis without filling up\ndisks.  The program can do some simple analysis and save only a summary of\nthe core dump.\n\nThe core dump proces will run with the privileges and in the name space of\nthe process that caused the core dump.\n\nI also increased the core pattern size to 128 bytes so that longer command\nlines fit.\n\nMost of the changes comes from allowing core dumps without seeks.  They are\nfairly straight forward though.\n\nOne small incompatibility is that if someone had a core pattern previously\nthat started with \u0027|\u0027 they will get suddenly new behaviour.  I think that\u0027s\nunlikely to be a real problem though.\n\nAdditional background:\n\n\u003e Very nice, do you happen to have a program that can accept this kind of\n\u003e input for crash dumps?  I\u0027m guessing that the embedded people will\n\u003e really want this functionality.\n\nI had a cheesy demo/prototype.  Basically it wrote the dump to a file again,\nran gdb on it to get a backtrace and wrote the summary to a shared directory.\nThen there was a simple CGI script to generate a \"top 10\" crashes HTML\nlisting.\n\nUnfortunately this still had the disadvantage to needing full disk space for a\ndump except for deleting it afterwards (in fact it was worse because over the\npipe holes didn\u0027t work so if you have a holey address map it would require\nmore space).\n\nFortunately gdb seems to be happy to handle /proc/pid/fd/xxx input pipes as\ncores (at least it worked with zsh\u0027s \u003d(cat core) syntax), so it would be\nlikely possible to do it without temporary space with a simple wrapper that\ncalls it in the right way.  I ran out of time before doing that though.\n\nThe demo prototype scripts weren\u0027t very good.  If there is really interest I\ncan dig them out (they are currently on a laptop disk on the desk with the\nlaptop itself being in service), but I would recommend to rewrite them for any\nserious application of this and fix the disk space problem.\n\nAlso to be really useful it should probably find a way to automatically fetch\nthe debuginfos (I cheated and just installed them in advance).  If nobody else\ndoes it I can probably do the rewrite myself again at some point.\n\nMy hope at some point was that desktops would support it in their builtin\ncrash reporters, but at least the KDE people I talked too seemed to be happy\nwith their user space only solution.\n\nAlan sayeth:\n\n  I don\u0027t believe that piping as such as neccessarily the right model, but\n  the ability to intercept and processes core dumps from user space is asked\n  for by many enterprise users as well.  They want to know about, capture,\n  analyse and process core dumps, often centrally and in automated form.\n\n[akpm@osdl.org: loff_t !\u003d unsigned long]\nSigned-off-by: Andi Kleen \u003cak@suse.de\u003e\nCc: Alan Cox \u003calan@lxorguk.ukuu.org.uk\u003e\nSigned-off-by: Andrew Morton \u003cakpm@osdl.org\u003e\nSigned-off-by: Linus Torvalds \u003ctorvalds@osdl.org\u003e\n"

This is useful we ever want to atomically traverse the\nprocess group and session lists, in a rcu safe manner.\n\nEven if the atomic properties this change should be a win as transfer_pid\nshould be less code to execute than executing both attach_pid and\ndetach_pid, and this should make de_thread slightly smaller as only a\nsingle function call needs to be emitted.

Now that\nwe demote the leader to a thread there is no longer any reason to change\nit\u0027s parentage.\n\nNot changing our ptrace parents is a user visible change if someone\nlooks hard enough.  I don\u0027t think user space applications will care or\neven notice.\n\nIn the practical and I think common case a debugger will have attached\nto all of the threads using the same ptrace flags.  From my quick skim\nof strace and gdb that appears to be the case.  Which if true means\ndebuggers will not notice a change.\n\nBefore this point we have already generated a ptrace event in do_exit\nthat reports the leaders pid has died so de_thread is visible to a\ndebugger.  Which means attempting to hide this case by copying flags\naround appears excessive.\n\nBy not doing anything it avoids all of the weird locking issues between\nde_thread and ptrace attach, and removes one case from consideration for\nfixing the ptrace locking.\n\nThis only addresses Oleg\u0027s first concern with ptrace_attach, that of the\nproblems caused by reparenting.  Oleg\u0027s second concern is essentially a\nrace between ptrace_attach and release_task that causes an oops when we\nget to force_sig_specific.

The simplest is a long standing double decrement of\n__get_cpu_var(process_counts) in __unhash_process.  Caused by\ntwo processes exiting when only one was created.\n\nThe other is that since we no longer detach from the thread_group list\nit is possible for do_each_thread when run under the tasklist_lock to\nsee the same task_struct twice.  Once on the task list as a\nthread_group_leader, and once on the thread list of another\nthread.\n\nThe double appearance in do_each_thread can cause a double increment\nof mm_core_waiters in zap_threads resulting in problems later on in\ncoredump_wait.\n\nTo remedy those two problems this patch takes the simple approach\nof changing the old thread group leader into a child thread.\nThe only routine in release_task that cares is __unhash_process,\nand it can be trivially seen that we handle cleaning up a\nthread group leader properly.\n\nSince de_thread doesn\u0027t change the pid of the exiting leader process\nand instead shares it with the new leader process.

These functions, openat etc, have been discussed on numerous\noccasions.  They are needed to implement race-free filesystem traversal,\nthey are necessary to implement a virtual per-thread current working\ndirectory (think multi-threaded backup software), etc.\n\nWe have in glibc today implementations of the interfaces which use the\n/proc/self/fd magic.  But this code is rather expensive.  Here are some\nresults (similar to what Jim Meyering posted before).\n\nThe test creates a deep directory hierarchy on a tmpfs filesystem.  Then\nrm -fr is used to remove all directories.  Without syscall support I get\nthis:\n\nreal    0m31.921s\nuser    0m0.688s\nsys     0m31.234s\n\nWith syscall support the results are much better:\n\nreal    0m20.699s\nuser    0m0.536s\nsys     0m20.149s\n\nThe interfaces are for obvious reasons currently not much used.  But they\u0027ll\nbe used.  coreutils (and Jeff\u0027s posixutils) are already using them.\nFurthermore, code like ftw/fts in libc (maybe even glob) will also start using\nthem.

This allows NFS to do\n    the right thing for O_TRUNC.\n  inode_setattr nolonger forces ATTR_MTIME|ATTR_CTIME when the ATTR_SIZE\n    sets the size to it\u0027s current value.  This allows local filesystems\n    to do the right thing for f?truncate.\n\nAlso, the logic in inode_setattr is changed a bit so there are two return\npoints.  One returns the error from vmtruncate if it failed, the other\nreturns 0 (there can be no other failure).\n\nFinally, if vmtruncate succeeds, and ATTR_SIZE is the only change\nrequested, we now fall-through and mark_inode_dirty.  If a filesystem did\nnot have a -\u003etruncate function, then vmtruncate will have changed i_size,\nwithout marking the inode as \u0027dirty\u0027, and I think this is wrong.\n\nSigned-off-by: Neil Brown \u003cneilb@suse.de\u003e\nCc: Christoph Hellwig \u003chch@lst.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"

Remove the temporary\nbridging hack from __pud_alloc, __pmd_alloc, __pte_alloc: expect callers not\nto hold page_table_lock, whether it\u0027s on init_mm or a user mm; take\npage_table_lock internally to check if a racing task already allocated.\n\nConvert their callers from common code.  But avoid coming back to change them\nagain later: instead of moving the spin_lock(\u0026mm-\u003epage_table_lock) down,\nswitch over to new macros pte_alloc_map_lock and pte_unmap_unlock, which\nencapsulate the mapping+locking and unlocking+unmapping together, and in the\nend may use alternatives to the mm page_table_lock itself.\n\nThese callers all hold mmap_sem (some exclusively, some not), so at no level\ncan a page table be whipped away from beneath them; and pte_alloc uses the\n\"atomic\" pmd_present to test whether it needs to allocate.

      "message": "[PATCH] mm: update_hiwaters just in time\n\nupdate_mem_hiwater has attracted various criticisms, in particular from those\nconcerned with mm scalability.  Originally it was called whenever rss or\ntotal_vm got raised.  Then many of those callsites were replaced by a timer\ntick call from account_system_time.  Now Frank van Maarseveen reports that to\nbe found inadequate.  How about this?  Works for Frank.\n\nReplace update_mem_hiwater, a poor combination of two unrelated ops, by macros\nupdate_hiwater_rss and update_hiwater_vm.  Don\u0027t attempt to keep\nmm-\u003ehiwater_rss up to date at timer tick, nor every time we raise rss (usually\nby 1): those are hot paths.  Do the opposite, update only when about to lower\nrss (usually by many), or just before final accounting in do_exit.  Handle\nmm-\u003ehiwater_vm in the same way, though it\u0027s much less of an issue.  Demand\nthat whoever collects these hiwater statistics do the work of taking the\nmaximum with rss or total_vm.\n\nAnd there has been no collector of these hiwater statistics in the tree.  The\nnew convention needs an example, so match Frank\u0027s usage by adding a VmPeak\nline above VmSize to /proc/\u003cpid\u003e/status, and also a VmHWM line above VmRSS\n(High-Water-Mark or High-Water-Memory).\n\nThere was a particular anomaly during mremap move, that hiwater_vm might be\ncaptured too high.  A fleeting such anomaly remains, but it\u0027s quickly\ncorrected now, whereas before it would stick.\n\nWhat locking?  None: if the app is racy then these statistics will be racy,\nit\u0027s not worth any overhead to make them exact.  But whenever it suits,\nhiwater_vm is updated under exclusive mmap_sem, and hiwater_rss under\npage_table_lock (for now) or with preemption disabled (later on): without\ngoing to any trouble, minimize the time between reading current values and\nupdating, to minimize those occasions when a racing thread bumps a count up\nand back down in between.\n\nSigned-off-by: Hugh Dickins \u003chugh@veritas.com\u003e\nSigned-off-by: Andrew Morton \u003cakpm@osdl.org\u003e\nSigned-off-by: Linus Torvalds \u003ctorvalds@osdl.org\u003e\n"
