The user\n  space interface is now complete.\n\n  This set of changes adds support for unprivileged users to create user\n  namespaces and as a user namespace root to create other namespaces.\n  The tyranny of supporting suid root preventing unprivileged users from\n  using cool new kernel features is broken.\n\n  This set of changes completes the work on setns, adding support for\n  the pid, user, mount namespaces.\n\n  This set of changes includes a bunch of basic pid namespace\n  cleanups/simplifications.  Of particular significance is the rework of\n  the pid namespace cleanup so it no longer requires sending out\n  tendrils into all kinds of unexpected cleanup paths for operation.  At\n  least one case of broken error handling is fixed by this cleanup.\n\n  The files under /proc/\u003cpid\u003e/ns/ have been converted from regular files\n  to magic symlinks which prevents incorrect caching by the VFS,\n  ensuring the files always refer to the namespace the process is\n  currently using and ensuring that the ptrace_mayaccess permission\n  checks are always applied.\n\n  The files under /proc/\u003cpid\u003e/ns/ have been given stable inode numbers\n  so it is now possible to see if different processes share the same\n  namespaces.\n\n  Through the David Miller\u0027s net tree are changes to relax many of the\n  permission checks in the networking stack to allowing the user\n  namespace root to usefully use the networking stack.  Similar changes\n  for the mount namespace and the pid namespace are coming through my\n  tree.\n\n  Two small changes to add user namespace support were commited here adn\n  in David Miller\u0027s -net tree so that I could complete the work on the\n  /proc/\u003cpid\u003e/ns/ files in this tree.\n\n  Work remains to make it safe to build user namespaces and 9p, afs,\n  ceph, cifs, coda, gfs2, ncpfs, nfs, nfsd, ocfs2, and xfs so the\n  Kconfig guard remains in place preventing that user namespaces from\n  being built when any of those filesystems are enabled.\n\n  Future design work remains to allow root users outside of the initial\n  user namespace to mount more than just /proc and /sys.\"\n\n* \u0027for-linus\u0027 of git://git.kernel.org/pub/scm/linux/kernel/git/ebiederm/user-namespace: (38 commits)\n  proc: Usable inode numbers for the namespace file descriptors.\n  proc: Fix the namespace inode permission checks.\n  proc: Generalize proc inode allocation\n  userns: Allow unprivilged mounts of proc and sysfs\n  userns: For /proc/self/{uid,gid}_map derive the lower userns from the struct file\n  procfs: Print task uids and gids in the userns that opened the proc file\n  userns: Implement unshare of the user namespace\n  userns: Implent proc namespace operations\n  userns: Kill task_user_ns\n  userns: Make create_new_namespaces take a user_ns parameter\n  userns: Allow unprivileged use of setns.\n  userns: Allow unprivileged users to create new namespaces\n  userns: Allow setting a userns mapping to your current uid.\n  userns: Allow chown and setgid preservation\n  userns: Allow unprivileged users to create user namespaces.\n  userns: Ignore suid and sgid on binaries if the uid or gid can not be mapped\n  userns: fix return value on mntns_install() failure\n  vfs: Allow unprivileged manipulation of the mount namespace.\n  vfs: Only support slave subtrees across different user namespaces\n  vfs: Add a user namespace reference from struct mnt_namespace\n  ...\n"

      "message": "mm: support more pagesizes for MAP_HUGETLB/SHM_HUGETLB\n\nThere was some desire in large applications using MAP_HUGETLB or\nSHM_HUGETLB to use 1GB huge pages on some mappings, and stay with 2MB on\nothers.  This is useful together with NUMA policy: use 2MB interleaving\non some mappings, but 1GB on local mappings.\n\nThis patch extends the IPC/SHM syscall interfaces slightly to allow\nspecifying the page size.\n\nIt borrows some upper bits in the existing flag arguments and allows\nencoding the log of the desired page size in addition to the *_HUGETLB\nflag.  When 0 is specified the default size is used, this makes the\nchange fully compatible.\n\nExtending the internal hugetlb code to handle this is straight forward.\nInstead of a single mount it just keeps an array of them and selects the\nright mount based on the specified page size.  When no page size is\nspecified it uses the mount of the default page size.\n\nThe change is not visible in /proc/mounts because internal mounts don\u0027t\nappear there.  It also has very little overhead: the additional mounts\njust consume a super block, but not more memory when not used.\n\nI also exported the new flags to the user headers (they were previously\nunder __KERNEL__).  Right now only symbols for x86 and some other\narchitecture for 1GB and 2MB are defined.  The interface should already\nwork for all other architectures though.  Only architectures that define\nmultiple hugetlb sizes actually need it (that is currently x86, tile,\npowerpc).  However tile and powerpc have user configurable hugetlb\nsizes, so it\u0027s not easy to add defines.  A program on those\narchitectures would need to query sysfs and use the appropiate log2.\n\n[akpm@linux-foundation.org: cleanups]\n[rientjes@google.com: fix build]\n[akpm@linux-foundation.org: checkpatch fixes]\nSigned-off-by: Andi Kleen \u003cak@linux.intel.com\u003e\nCc: Michael Kerrisk \u003cmtk.manpages@gmail.com\u003e\nAcked-by: Rik van Riel \u003criel@redhat.com\u003e\nAcked-by: KAMEZAWA Hiroyuki \u003ckamezawa.hiroyu@jp.fujitsu.com\u003e\nCc: Hillf Danton \u003cdhillf@gmail.com\u003e\nSigned-off-by: David Rientjes \u003crientjes@google.com\u003e\nSigned-off-by: Andrew Morton \u003cakpm@linux-foundation.org\u003e\nSigned-off-by: Linus Torvalds \u003ctorvalds@linux-foundation.org\u003e\n"

This allows the code to code to compile with user namespaces\n  enabled and removes the assumption there is only the initial user\n  namespace.  Everything is converted except for the most complex of the\n  filesystems: autofs4, 9p, afs, ceph, cifs, coda, fuse, gfs2, ncpfs,\n  nfs, ocfs2 and xfs as those patches need a bit more review.\n\n  The strategy is to push kuid_t and kgid_t values are far down into\n  subsystems and filesystems as reasonable.  Leaving the make_kuid and\n  from_kuid operations to happen at the edge of userspace, as the values\n  come off the disk, and as the values come in from the network.\n  Letting compile type incompatible compile errors (present when user\n  namespaces are enabled) guide me to find the issues.\n\n  The most tricky areas have been the places where we had an implicit\n  union of uid and gid values and were storing them in an unsigned int.\n  Those places were converted into explicit unions.  I made certain to\n  handle those places with simple trivial patches.\n\n  Out of that work I discovered we have generic interfaces for storing\n  quota by projid.  I had never heard of the project identifiers before.\n  Adding full user namespace support for project identifiers accounts\n  for most of the code size growth in my git tree.\n\n  Ultimately there will be work to relax privlige checks from\n  \"capable(FOO)\" to \"ns_capable(user_ns, FOO)\" where it is safe allowing\n  root in a user names to do those things that today we only forbid to\n  non-root users because it will confuse suid root applications.\n\n  While I was pushing kuid_t and kgid_t changes deep into the audit code\n  I made a few other cleanups.  I capitalized on the fact we process\n  netlink messages in the context of the message sender.  I removed\n  usage of NETLINK_CRED, and started directly using current-\u003etty.\n\n  Some of these patches have also made it into maintainer trees, with no\n  problems from identical code from different trees showing up in\n  linux-next.\n\n  After reading through all of this code I feel like I might be able to\n  win a game of kernel trivial pursuit.\"\n\nFix up some fairly trivial conflicts in netfilter uid/git logging code.\n\n* \u0027for-linus\u0027 of git://git.kernel.org/pub/scm/linux/kernel/git/ebiederm/user-namespace: (107 commits)\n  userns: Convert the ufs filesystem to use kuid/kgid where appropriate\n  userns: Convert the udf filesystem to use kuid/kgid where appropriate\n  userns: Convert ubifs to use kuid/kgid\n  userns: Convert squashfs to use kuid/kgid where appropriate\n  userns: Convert reiserfs to use kuid and kgid where appropriate\n  userns: Convert jfs to use kuid/kgid where appropriate\n  userns: Convert jffs2 to use kuid and kgid where appropriate\n  userns: Convert hpfs to use kuid and kgid where appropriate\n  userns: Convert btrfs to use kuid/kgid where appropriate\n  userns: Convert bfs to use kuid/kgid where appropriate\n  userns: Convert affs to use kuid/kgid wherwe appropriate\n  userns: On alpha modify linux_to_osf_stat to use convert from kuids and kgids\n  userns: On ia64 deal with current_uid and current_gid being kuid and kgid\n  userns: On ppc convert current_uid from a kuid before printing.\n  userns: Convert s390 getting uid and gid system calls to use kuid and kgid\n  userns: Convert s390 hypfs to use kuid and kgid where appropriate\n  userns: Convert binder ipc to use kuids\n  userns: Teach security_path_chown to take kuids and kgids\n  userns: Add user namespace support to IMA\n  userns: Convert EVM to deal with kuids and kgids in it\u0027s hmac computation\n  ...\n"

      "message": "ipc/mqueue: add rbtree node caching support\n\nWhen I wrote the first patch that added the rbtree support for message\nqueue insertion, it sped up the case where the queue was very full\ndrastically from the original code.  It, however, slowed down the case\nwhere the queue was empty (not drastically though).\n\nThis patch caches the last freed rbtree node struct so we can quickly\nreuse it when we get a new message.  This is the common path for any queue\nthat very frequently goes from 0 to 1 then back to 0 messages in queue.\n\nAndrew Morton didn\u0027t like that we were doing a GFP_ATOMIC allocation in\nmsg_insert, so this patch attempts to speculatively allocate a new node\nstruct outside of the spin lock when we know we need it, but will still\nfall back to a GFP_ATOMIC allocation if it has to.\n\nOnce I added the caching, the necessary various ret \u003d ; spin_unlock\ngyrations in mq_timedsend were getting pretty ugly, so this also slightly\nrefactors that function to streamline the flow of the code and the\nfunction exit.\n\nFinally, while working on getting performance back I made sure that all of\nthe node structs were always fully initialized when they were first used,\nrendering the use of kzalloc unnecessary and a waste of CPU cycles.\n\nThe net result of all of this is:\n\n1) We will avoid a GFP_ATOMIC allocation when possible, but fall back\n   on it when necessary.\n\n2) We will speculatively allocate a node struct using GFP_KERNEL if our\n   cache is empty (and save the struct to our cache if it\u0027s still empty\n   after we have obtained the spin lock).\n\n3) The performance of the common queue empty case has significantly\n   improved and is now much more in line with the older performance for\n   this case.\n\nThe performance changes are:\n\n            Old mqueue      new mqueue      new mqueue + caching\nqueue empty\nsend/recv   305/288ns       349/318ns       310/322ns\n\nI don\u0027t think we\u0027ll ever be able to get the recv performance back, but\nthat\u0027s because the old recv performance was a direct result and\nconsequence of the old methods abysmal send performance.  The recv path\nsimply must do more so that the send path does not incur such a penalty\nunder higher queue depths.\n\nAs it turns out, the new caching code also sped up the various queue full\ncases relative to my last patch.  That could be because of the difference\nbetween the syscall path in 3.3.4-rc5 and 3.3.4-rc6, or because of the\nchange in code flow in the mq_timedsend routine.  Regardless, I\u0027ll take\nit.  It wasn\u0027t huge, and I *would* say it was within the margin for error,\nbut after many repeated runs what I\u0027m seeing is that the old numbers trend\nslightly higher (about 10 to 20ns depending on which test is the one\nrunning).\n\n[akpm@linux-foundation.org: checkpatch fixes]\nSigned-off-by: Doug Ledford \u003cdledford@redhat.com\u003e\nCc: Frederic Weisbecker \u003cfweisbec@gmail.com\u003e\nCc: Manfred Spraul \u003cmanfred@colorfullife.com\u003e\nCc: Stephen Rothwell \u003csfr@canb.auug.org.au\u003e\nCc: KOSAKI Motohiro \u003ckosaki.motohiro@jp.fujitsu.com\u003e\nSigned-off-by: Andrew Morton \u003cakpm@linux-foundation.org\u003e\nSigned-off-by: Linus Torvalds \u003ctorvalds@linux-foundation.org\u003e\n"

      "message": "ipc/mqueue: improve performance of send/recv\n\nThe existing implementation of the POSIX message queue send and recv\nfunctions is, well, abysmal.  Even worse than abysmal.  I submitted a\npatch to increase the maximum POSIX message queue limit to 65536 due to\ncustomer needs, however, upon looking over the send/recv implementation, I\nrealized that my customer needs help with that too even if they don\u0027t know\nit.  The basic problem is that, given the fairly typical use case scenario\nfor a large queue of queueing lots of messages all at the same priority (I\nverified with my customer that this is indeed what their app does), the\nmsg_insert routine is basically a frikkin\u0027 bubble sort.  I mean, whoa,\nthat\u0027s *so* middle school.\n\nOK, OK, to not slam the original author too much, I\u0027m sure they didn\u0027t\nenvision a queue depth of 50,000+ messages.  No one would think that\nmoving elements in an array, one at a time, and dereferencing each pointer\nin that array to check priority of the message being pointed too, again\none at a time, for 50,000+ times would be good.  So let\u0027s assume that, as\nis typical, the users have found a way to break our code simply by using\nit in a way we didn\u0027t envision.  Fair enough.\n\n\"So, just how broken is it?\", you ask.  I wondered the same thing, so I\nwrote an app to let me know.  It\u0027s my next patch.  It gave me some\ninteresting results.  Here\u0027s what it tested:\n\nInterference with other apps - In continuous mode, the app just sits there\nand hits a message queue forever, while you go do something productive on\nanother terminal using other CPUs.  You then measure how long it takes you\nto do that something productive.  Then you restart the app in fake\ncontinuous mode, and it sits in a tight loop on a CPU while you repeat\nyour tests.  The whole point of this is to keep one CPU tied up (so it\ncan\u0027t be used in your other work) but in one case tied up hitting the\nmqueue code so we can see the effect of walking that 65,528 element array\none pointer at a time on the global CPU cache.  If it\u0027s bad, then it will\nslow down your app on the other CPUs just by polluting cache mercilessly.\nIn the fake case, it will be in a tight loop, but not polluting cache.\nTesting the mqueue subsystem directly - Here we just run a number of tests\nto see how the mqueue subsystem performs under different conditions.  A\ncouple conditions are known to be worst case for the old system, and some\nroutines, so this tests all of them.\n\nSo, on to the results already:\n\nSubsystem/Test                  Old                         New\n\nTime to compile linux\nkernel (make -j12 on a\n6 core CPU)\n  Running mqueue test     user 49m10.744s             user 45m26.294s\n\t\t\t   sys  5m51.924s              sys  4m59.894s\n\t\t\t total 55m02.668s            total 50m26.188s\n\n  Running fake test       user 45m32.686s             user 45m18.552s\n                           sys  5m12.465s              sys  4m56.468s\n                         total 50m45.151s            total 50m15.020s\n\n  % slowdown from mqueue\n    cache thrashing            ~8%                         ~.5%\n\nAvg time to send/recv (in nanoseconds per message)\n  when queue empty            305/288                    349/318\n  when queue full (65528 messages)\n    constant priority      526589/823                    362/314\n    increasing priority    403105/916                    495/445\n    decreasing priority     73420/594                    482/409\n    random priority        280147/920                    546/436\n\nTime to fill/drain queue (65528 messages, in seconds)\n  constant priority         17.37/.12                    .13/.12\n  increasing priority        4.14/.14                    .21/.18\n  decreasing priority       12.93/.13                    .21/.18\n  random priority            8.88/.16                    .22/.17\n\nSo, I think the results speak for themselves.  It\u0027s possible this\nimplementation could be improved by cacheing at least one priority level\nin the node tree (that would bring the queue empty performance more in\nline with the old implementation), but this works and is *so* much better\nthan what we had, especially for the common case of a single priority in\nuse, that further refinements can be in follow on patches.\n\n[akpm@linux-foundation.org: fix typo in comment, remove stray semicolon]\n[levinsasha928@gmail.com: use correct gfp flags in msg_insert]\nSigned-off-by: Doug Ledford \u003cdledford@redhat.com\u003e\nCc: Stephen Rothwell \u003csfr@canb.auug.org.au\u003e\nCc: Manfred Spraul \u003cmanfred@colorfullife.com\u003e\nAcked-by: KOSAKI Motohiro \u003ckosaki.motohiro@jp.fujitsu.com\u003e\nSigned-off-by: Sasha Levin \u003clevinsasha928@gmail.com\u003e\nSigned-off-by: Andrew Morton \u003cakpm@linux-foundation.org\u003e\nSigned-off-by: Linus Torvalds \u003ctorvalds@linux-foundation.org\u003e\n"

After reviewing POSIX, we found\nthat it is silent on the maximum message size.  We did find a couple other\nareas in which it was not silent.  Fix up the mqueue maximums so that the\ncustomer\u0027s system can continue to work, and document both the POSIX and\nreal world requirements in ipc_namespace.h so that we don\u0027t have this\nissue crop back up.\n\nAlso, commit 9cf18e1dd74cd0 (\"ipc: HARD_MSGMAX should be higher not lower\non 64bit\") fiddled with HARD_MSGMAX without realizing that the number was\nintentionally in place to limit the msg queue depth to one that was small\nenough to kmalloc an array of pointers (hence why we divided 128k by\nsizeof(long)).  If we wish to meet POSIX requirements, we have no choice\nbut to change our allocation to a vmalloc instead (at least for the large\nqueue size case).  With that, it\u0027s possible to increase our allowed\nmaximum to the POSIX requirements (or more if we choose).\n\n[sfr@canb.auug.org.au: using vmalloc requires including vmalloc.h]\nSigned-off-by: Doug Ledford \u003cdledford@redhat.com\u003e\nCc: Serge E.

Switch back to using acceptable defaults regardless of what the\nmaximums are.\n\nNote: so far, we only know of a few applications that rely on this\nbehavior (specifically, set the maximums in /proc, then run the\napplication which calls mq_open() without passing in an attr struct, and\nthe application expects the newly created message queue to have the\nmaximum sizes that were set in /proc used on the mq_open() call, and all\nof those applications that we know of are actually part of regression\ntest suites that were coded to do something like this:\n\nfor size in 4096 65536 $((1024 * 1024)) $((16 * 1024 * 1024)); do\n\techo $size \u003e /proc/sys/fs/mqueue/msgsize_max\n\tmq_open || echo \"Error opening mq with size $size\"\ndone\n\nThese test suites that depend on any behavior like this are broken.  The\nconcept that programs should rely upon the system wide maximum in order\nto get their desired results instead of simply using a attr struct to\nspecify what they want is fundamentally unfriendly programming practice\nfor any multi-tasking OS.\n\nFixing this will break those few apps that we know of (and those app\nauthors recognize the brokenness of their code and the need to fix it).\nHowever, the following patch \"mqueue: separate mqueue default value\"\nallows a workaround in the form of new knobs for the default msg queue\ncreation parameters for any software out there that we don\u0027t already\nknow about that might rely on this behavior at the moment.\n\nSigned-off-by: Doug Ledford \u003cdledford@redhat.com\u003e\nCc: Serge E.

      "message": "ipc/mqueue: cleanup definition names and locations\n\nSince commit b231cca4381e (\"message queues: increase range limits\") on\nOct 18, 2008, calls to mq_open() that did not pass in an attribute\nstruct and expected to get default values for the size of the queue and\nthe max message size now get the system wide maximums instead of\nhardwired defaults like they used to get.\n\nThis was uncovered when one of the earlier patches in this patch set\nincreased the default system wide maximums at the same time it increased\nthe hard ceiling on the system wide maximums (a customer specifically\nneeded the hard ceiling brought back up, the new ceiling that commit\nb231cca4381e introduced was too low for their production systems).  By\nincreasing the default maximums and not realising they were tied to any\nattempt to create a message queue without an attribute struct, I had\ninadvertently made it such that all message queue creation attempts\nwithout an attribute struct were failing because the new default\nmaximums would create a queue that exceeded the default rlimit for\nmessage queue bytes.\n\nAs a result, the system wide defaults were brought back down to their\nprevious levels, and the system wide ceilings on the maximums were\nraised to meet the customer\u0027s needs.  However, the fact that the no\nattribute struct behavior of mq_open() could be broken by changing the\nsystem wide maximums for message queues was seen as fundamentally broken\nitself.  So we hardwired the no attribute case back like it used to be.\nBut, then we realized that on the very off chance that some piece of\nsoftware in the wild depended on that behavior, we could work around\nthat issue by adding two new knobs to /proc that allowed setting the\ndefaults for message queues created without an attr struct separately\nfrom the system wide maximums.\n\nWhat is not an option IMO is to leave the current behavior in place.  No\npiece of software should ever rely on setting the system wide maximums\nin order to get a desired message queue.  Such a reliance would be so\nfundamentally multitasking OS unfriendly as to not really be tolerable.\nFortunately, we don\u0027t know of any software in the wild that uses this\nexcept for a regression test program that caught the issue in the first\nplace.  If there is though, we have made accommodations with the two new\n/proc knobs (and that\u0027s all the accommodations such fundamentally broken\nsoftware can be allowed)..\n\nThis patch:\n\nThe various defines for minimums and maximums of the sysctl controllable\nmqueue values are scattered amongst different files and named\ninconsistently.  Move them all into ipc_namespace.h and make them have\nconsistent names.  Additionally, make the number of queues per namespace\nalso have a minimum and maximum and use the same sysctl function as the\nother two settable variables.\n\nSigned-off-by: Doug Ledford \u003cdledford@redhat.com\u003e\nAcked-by: Serge E.

      "message": "[PATCH v3] ipc: provide generic compat versions of IPC syscalls\n\nWhen using the \"compat\" APIs, architectures will generally want to\nbe able to make direct syscalls to msgsnd(), shmctl(), etc., and\nin the kernel we would want them to be handled directly by\ncompat_sys_xxx() functions, as is true for other compat syscalls.\n\nHowever, for historical reasons, several of the existing compat IPC\nsyscalls do not do this.  semctl() expects a pointer to the fourth\nargument, instead of the fourth argument itself.  msgsnd(), msgrcv()\nand shmat() expect arguments in different order.\n\nThis change adds an ARCH_WANT_OLD_COMPAT_IPC config option that can be\nset to preserve this behavior for ports that use it (x86, sparc, powerpc,\ns390, and mips).  No actual semantics are changed for those architectures,\nand there is only a minimal amount of code refactoring in ipc/compat.c.\n\nNewer architectures like tile (and perhaps future architectures such\nas arm64 and unicore64) should not select this option, and thus can\navoid having any IPC-specific code at all in their architecture-specific\ncompat layer.  In the same vein, if this option is not selected, IPC_64\nmode is assumed, since that\u0027s what the \u003casm-generic\u003e headers expect.\n\nThe workaround code in \"tile\" for msgsnd() and msgrcv() is removed\nwith this change; it also fixes the bug that shmat() and semctl() were\nnot being properly handled.\n\nReviewed-by: Arnd Bergmann \u003carnd@arndb.de\u003e\nSigned-off-by: Chris Metcalf \u003ccmetcalf@tilera.com\u003e\n"

      "message": "SHM_UNLOCK: fix Unevictable pages stranded after swap\n\nCommit cc39c6a9bbde (\"mm: account skipped entries to avoid looping in\nfind_get_pages\") correctly fixed an infinite loop; but left a problem\nthat find_get_pages() on shmem would return 0 (appearing to callers to\nmean end of tree) when it meets a run of nr_pages swap entries.\n\nThe only uses of find_get_pages() on shmem are via pagevec_lookup(),\ncalled from invalidate_mapping_pages(), and from shmctl SHM_UNLOCK\u0027s\nscan_mapping_unevictable_pages().  The first is already commented, and\nnot worth worrying about; but the second can leave pages on the\nUnevictable list after an unusual sequence of swapping and locking.\n\nFix that by using shmem_find_get_pages_and_swap() (then ignoring the\nswap) instead of pagevec_lookup().\n\nBut I don\u0027t want to contaminate vmscan.c with shmem internals, nor\nshmem.c with LRU locking.  So move scan_mapping_unevictable_pages() into\nshmem.c, renaming it shmem_unlock_mapping(); and rename\ncheck_move_unevictable_page() to check_move_unevictable_pages(), looping\ndown an array of pages, oftentimes under the same lock.\n\nLeave out the \"rotate unevictable list\" block: that\u0027s a leftover from\nwhen this was used for /proc/sys/vm/scan_unevictable_pages, whose flawed\nhandling involved looking at pages at tail of LRU.\n\nWas there significance to the sequence first ClearPageUnevictable, then\ntest page_evictable, then SetPageUnevictable here? I think not, we\u0027re\nunder LRU lock, and have no barriers between those.\n\nSigned-off-by: Hugh Dickins \u003chughd@google.com\u003e\nReviewed-by: KOSAKI Motohiro \u003ckosaki.motohiro@jp.fujitsu.com\u003e\nCc: Minchan Kim \u003cminchan.kim@gmail.com\u003e\nCc: Rik van Riel \u003criel@redhat.com\u003e\nCc: Shaohua Li \u003cshaohua.li@intel.com\u003e\nCc: Eric Dumazet \u003ceric.dumazet@gmail.com\u003e\nCc: Johannes Weiner \u003channes@cmpxchg.org\u003e\nCc: Michel Lespinasse \u003cwalken@google.com\u003e\nCc: \u003cstable@vger.kernel.org\u003e [back to 3.1 but will need respins]\nSigned-off-by: Andrew Morton \u003cakpm@linux-foundation.org\u003e\nSigned-off-by: Linus Torvalds \u003ctorvalds@linux-foundation.org\u003e\n"

It does this with\npagevec_lookup()s across the whole object (which might occupy most of\nmemory), and takes 300ms to unlock 7GB here.  A cond_resched() every\nPAGEVEC_SIZE pages would be good.\n\nHowever, KOSAKI-san points out that this is called under shmem.c\u0027s\ninfo-\u003elock, and it\u0027s also under shm.c\u0027s shm_lock(), both spinlocks.\nThere is no strong reason for that: we need to take these pages off the\nunevictable list soonish, but those locks are not required for it.\n\nSo move the call to scan_mapping_unevictable_pages() from shmem.c\u0027s\nunlock handling up to shm.c\u0027s unlock handling.  Remove the recently\nadded barrier, not needed now we have spin_unlock() before the scan.\n\nUse get_file(), with subsequent fput(), to make sure we have a reference\nto mapping throughout scan_mapping_unevictable_pages(): that\u0027s something\nthat was previously guaranteed by the shm_lock().\n\nRemove shmctl\u0027s lru_add_drain_all(): we don\u0027t fault in pages at SHM_LOCK\ntime, and we lazily discover them to be Unevictable later, so it serves\nno purpose for SHM_LOCK; and serves no purpose for SHM_UNLOCK, since\npages still on pagevec are not marked Unevictable.\n\nThe original code avoided redundant rescans by checking VM_LOCKED flag\nat its level: now avoid them by checking shp\u0027s SHM_LOCKED.\n\nThe original code called scan_mapping_unevictable_pages() on a locked\narea at shm_destroy() time: perhaps we once had accounting cross-checks\nwhich required that, but not now, so skip the overhead and just let\ninode eviction deal with them.\n\nPut check_move_unevictable_page() and scan_mapping_unevictable_pages()\nunder CONFIG_SHMEM (with stub for the TINY case when ramfs is used),\nmore as comment than to save space; comment them used for SHM_UNLOCK.\n\nSigned-off-by: Hugh Dickins \u003chughd@google.com\u003e\nReviewed-by: KOSAKI Motohiro \u003ckosaki.motohiro@jp.fujitsu.com\u003e\nCc: Minchan Kim \u003cminchan.kim@gmail.com\u003e\nCc: Rik van Riel \u003criel@redhat.com\u003e\nCc: Shaohua Li \u003cshaohua.li@intel.com\u003e\nCc: Eric Dumazet \u003ceric.dumazet@gmail.com\u003e\nCc: Johannes Weiner \u003channes@cmpxchg.org\u003e\nCc: Michel Lespinasse \u003cwalken@google.com\u003e\nSigned-off-by: Andrew Morton \u003cakpm@linux-foundation.org\u003e\nSigned-off-by: Linus Torvalds \u003ctorvalds@linux-foundation.org\u003e\n"

Passing the target task would\n\tmake callers even easier to read, but we pass in user_ns because\n\tcurrent_user_ns() !\u003d task_cred_xxx(current, user_ns).\nSep 20: As recommended by Oleg, also put task_pid_vnr() under rcu_read_lock\n\tin ptrace_signal().\nSep 23: In send_signal(), detect when (user) signal is coming from an\n\tancestor or unrelated user namespace.  Pass that on to __send_signal,\n\twhich sets si_uid to 0 or overflowuid if needed.\nOct 12: Base on Oleg\u0027s fixup_uid() patch.  On top of that, handle all\n\tSI_FROMKERNEL cases at callers, because we can\u0027t assume sender is\n\tcurrent in those cases.\nNov 10: (mhelsley) rename fixup_uid to more meaningful usern_fixup_signal_uid\nNov 10: (akpm) make the !CONFIG_USER_NS case clearer\n\nSigned-off-by: Serge Hallyn \u003cserge.hallyn@canonical.com\u003e\nCc: Oleg Nesterov \u003coleg@redhat.com\u003e\nCc: Matt Helsley \u003cmatthltc@us.ibm.com\u003e\nCc: \"Eric W.
