This hid two\nformat errors - shp-\u003eshm_segsz and shp-\u003eshm_nattach are both unsigned\nlong, but were being printed as unsigned int and signed int respectively.\nThis leads to 32-bit truncation of SHM segment sizes reported in\n/proc/sysvipc/shm.

In\nsome cases up to 32K. However simply setting MSGMNI to a larger value may\ncause problems for smaller systems.\n\nThe first patch of this series introduces a default maximum number of message\nqueue ids that scales with the amount of lowmem.\n\nSince msgmni is per namespace and there is no amount of memory dedicated to\neach namespace so far, the second patch of this series scales msgmni to the\nnumber of ipc namespaces too.\n\nSince msgmni depends on the amount of memory, it becomes necessary to\nrecompute it upon memory add/remove. In the 4th patch, memory hotplug\nmanagement is added: a notifier block is registered into the memory hotplug\nnotifier chain for the ipc subsystem. Since the ipc namespaces are not linked\ntogether, they have their own notification chain: one notifier_block is\ndefined per ipc namespace. Each time an ipc namespace is created (removed) it\nregisters (unregisters) its notifier block in (from) the ipcns chain. The\ncallback routine registered in the memory chain invokes the ipcns notifier\nchain with the IPCNS_MEMCHANGE event. Each callback routine registered in the\nipcns namespace, in turn, recomputes msgmni for the owning namespace.\n\nThe 5th patch makes it possible to keep the memory hotplug notifier chain\u0027s\nlock for a lesser amount of time: instead of directly notifying the ipcns\nnotifier chain upon memory add/remove, a work item is added to the global\nworkqueue. When activated, this work item is the one who notifies the ipcns\nnotifier chain.\n\nSince msgmni depends on the number of ipc namespaces, it becomes necessary to\nrecompute it upon ipc namespace creation / removal. The 6th patch uses the\nipc namespace notifier chain for that purpose: that chain is notified each\ntime an ipc namespace is created or removed. This makes it possible to\nrecompute msgmni for all the namespaces each time one of them is created or\nremoved.\n\nWhen msgmni is explicitely set from userspace, we should avoid recomputing it\nupon memory add/remove or ipcns creation/removal. This is what the 7th patch\ndoes: it simply unregisters the ipcns callback routine as soon as msgmni has\nbeen changed from procfs or sysctl().\n\nEven if msgmni is set by hand, it should be possible to make it back\nautomatically recomputed upon memory add/remove or ipcns creation/removal.\nThis what is achieved in patch 8: if set to a negative value, msgmni is added\nback to the ipcns notifier chain, making it automatically recomputed again.\n\nThis patch:\n\nCompute msg_ctlmni to make it scale with the amount of lowmem. msg_ctlmni is\nnow set to make the message queues occupy 1/32 of the available lowmem.\n\nSome cleaning has also been done for the MSGPOOL constant: the msgctl man page\nsays it\u0027s not used, but it also defines it as a size in bytes (the code\nexpresses it in Kbytes).\n\nSigned-off-by: Nadia Derbey \u003cNadia.Derbey@bull.net\u003e\nCc: Yasunori Goto \u003cy-goto@jp.fujitsu.com\u003e\nCc: Matt Helsley \u003cmatthltc@us.ibm.com\u003e\nCc: Mingming Cao \u003ccmm@us.ibm.com\u003e\nCc: Pierre Peiffer \u003cpierre.peiffer@bull.net\u003e\nSigned-off-by: Andrew Morton \u003cakpm@linux-foundation.org\u003e\nSigned-off-by: Linus Torvalds \u003ctorvalds@linux-foundation.org\u003e\n" }, { "commit": "48dea404ed01869313f1908cca8a15774dcd8ee5", "tree": "c4c50c9032556cf96b21f8704e4544998769b6b9", "parents": [ "02d15c43225afb2ebb6d700144285175a1c4abd9" ], "author": { "name": "Pierre Peiffer", "email": "pierre.peiffer@bull.net", "time": "Tue Apr 29 01:00:35 2008 -0700" }, "committer": { "name": "Linus Torvalds", "email": "torvalds@linux-foundation.org", "time": "Tue Apr 29 08:06:12 2008 -0700" }, "message": "IPC: use ipc_buildid() directly from ipc_addid()\n\nBy continuing to consolidate a little the IPC code, each id can be built\ndirectly in ipc_addid() instead of having it built from each callers of\nipc_addid()\n\nAnd I also remove shm_addid() in order to have, as much as possible, the\nsame code for shm/sem/msg.\n\n[akpm@linux-foundation.org: coding-style fixes]\nSigned-off-by: Pierre Peiffer \u003cpierre.peiffer@bull.net\u003e\nCc: Nadia Derbey \u003cNadia.Derbey@bull.net\u003e\nSigned-off-by: Andrew Morton \u003cakpm@linux-foundation.org\u003e\nSigned-off-by: Linus Torvalds \u003ctorvalds@linux-foundation.org\u003e\n" }, { "commit": "52cd3b074050dd664380b5e8cfc85d4a6ed8ad48", "tree": "fcfcf55c0e81376ea34919fab26e29bedd7f3b88", "parents": [ "a6020ed759404372e8be2b276e85e51735472cc9" ], "author": { "name": "Lee Schermerhorn", "email": "lee.schermerhorn@hp.com", "time": "Mon Apr 28 02:13:16 2008 -0700" }, "committer": { "name": "Linus Torvalds", "email": "torvalds@linux-foundation.org", "time": "Mon Apr 28 08:58:24 2008 -0700" }, "message": "mempolicy: rework mempolicy Reference Counting [yet again]\n\nAfter further discussion with Christoph Lameter, it has become clear that my\nearlier attempts to clean up the mempolicy reference counting were a bit of\noverkill in some areas, resulting in superflous ref/unref in what are usually\nfast paths. In other areas, further inspection reveals that I botched the\nunref for interleave policies.\n\nA separate patch, suitable for upstream/stable trees, fixes up the known\nerrors in the previous attempt to fix reference counting.\n\nThis patch reworks the memory policy referencing counting and, one hopes,\nsimplifies the code. Maybe I\u0027ll get it right this time.\n\nSee the update to the numa_memory_policy.txt document for a discussion of\nmemory policy reference counting that motivates this patch.\n\nSummary:\n\nLookup of mempolicy, based on (vma, address) need only add a reference for\nshared policy, and we need only unref the policy when finished for shared\npolicies. So, this patch backs out all of the unneeded extra reference\ncounting added by my previous attempt. It then unrefs only shared policies\nwhen we\u0027re finished with them, using the mpol_cond_put() [conditional put]\nhelper function introduced by this patch.\n\nNote that shmem_swapin() calls read_swap_cache_async() with a dummy vma\ncontaining just the policy. read_swap_cache_async() can call alloc_page_vma()\nmultiple times, so we can\u0027t let alloc_page_vma() unref the shared policy in\nthis case. To avoid this, we make a copy of any non-null shared policy and\nremove the MPOL_F_SHARED flag from the copy. This copy occurs before reading\na page [or multiple pages] from swap, so the overhead should not be an issue\nhere.\n\nI introduced a new static inline function \"mpol_cond_copy()\" to copy the\nshared policy to an on-stack policy and remove the flags that would require a\nconditional free. The current implementation of mpol_cond_copy() assumes that\nthe struct mempolicy contains no pointers to dynamically allocated structures\nthat must be duplicated or reference counted during copy.\n\nSigned-off-by: Lee Schermerhorn \u003clee.schermerhorn@hp.com\u003e\nCc: Christoph Lameter \u003cclameter@sgi.com\u003e\nCc: David Rientjes \u003crientjes@google.com\u003e\nCc: Mel Gorman \u003cmel@csn.ul.ie\u003e\nCc: Andi Kleen \u003cak@suse.de\u003e\nSigned-off-by: Andrew Morton \u003cakpm@linux-foundation.org\u003e\nSigned-off-by: Linus Torvalds \u003ctorvalds@linux-foundation.org\u003e\n" }, { "commit": "ae4d8c16aa22775f5731677abb8a82f03cec877e", "tree": "2d34c6fd334b51cc5f3265cd4ec26db758639b5c", "parents": [ "f4e53d910b7dde2685b177f1e7c3e3e0b4a42f7b" ], "author": { "name": "Lee Schermerhorn", "email": "lee.schermerhorn@hp.com", "time": "Mon Apr 28 02:13:11 2008 -0700" }, "committer": { "name": "Linus Torvalds", "email": "torvalds@linux-foundation.org", "time": "Mon Apr 28 08:58:24 2008 -0700" }, "message": "mempolicy: fixup Fallback for Default Shmem Policy\n\nget_vma_policy() is not handling fallback to task policy correctly when the\nget_policy() vm_op returns NULL.

However, that series will require testing in -mm once\nI repost it.\n\n1) alloc_page_vma() does not release the extra reference taken for\n vma/shared mempolicy when the mode \u003d\u003d MPOL_INTERLEAVE. This can result in\n leaking mempolicy structures. This is probably occurring, but not being\n noticed.\n\n Fix: add the conditional release of the reference.\n\n2) hugezonelist unconditionally releases a reference on the mempolicy when\n mode \u003d\u003d MPOL_INTERLEAVE. This can result in decrementing the reference\n count for system default policy [should have no ill effect] or premature\n freeing of task policy. If this occurred, the next allocation using task\n mempolicy would use the freed structure and probably BUG out.\n\n Fix: add the necessary check to the release.\n\n3) The current reference counting method assumes that vma \u0027get_policy()\u0027\n methods automatically add an extra reference a non-NULL returned mempolicy.\n This is true for shmem_get_policy() used by tmpfs mappings, including\n regular page shm segments. However, SHM_HUGETLB shm\u0027s, backed by\n hugetlbfs, just use the vma policy without the extra reference. This\n results in freeing of the vma policy on the first allocation, with reuse of\n the freed mempolicy structure on subsequent allocations.\n\n Fix: Rather than add another condition to the conditional reference\n release, which occur in the allocation path, just add a reference when\n returning the vma policy in shm_get_policy() to match the assumptions.\n\nSigned-off-by: Lee Schermerhorn \u003clee.schermerhorn@hp.com\u003e\nCc: Greg KH \u003cgreg@kroah.com\u003e\nCc: Andi Kleen \u003cak@suse.de\u003e\nCc: Christoph Lameter \u003cclameter@sgi.com\u003e\nCc: Mel Gorman \u003cmel@csn.ul.ie\u003e\nCc: David Rientjes \u003crientjes@google.com\u003e\nCc: \u003ceric.whitney@hp.com\u003e\nSigned-off-by: Andrew Morton \u003cakpm@linux-foundation.org\u003e\nSigned-off-by: Linus Torvalds \u003ctorvalds@linux-foundation.org\u003e\n" }, { "commit": "56496c1d83dfae0c74e2f43adb45d2d95e16c0d5", "tree": "36cdf6421d0b26e8372dd1167a1ecd18f73fc3a5", "parents": [ "6c5f3e7b43300508fe3947ff3cfff0f86043bb57" ], "author": { "name": "Pavel Emelyanov", "email": "xemul@openvz.org", "time": "Fri Feb 08 04:19:21 2008 -0800" }, "committer": { "name": "Linus Torvalds", "email": "torvalds@woody.linux-foundation.org", "time": "Fri Feb 08 09:22:29 2008 -0800" }, "message": "Pidns: fix badly converted mqueues pid handling\n\nWhen sending the pid namespaces patches I wrongly converted the tsk-\u003etgid into\ntask_pid_vnr(tsk) in mqueue-s (the git id of this patch is\nb488893a390edfe027bae7a46e9af8083e740668).\n\nThe proper behavior is to get the task_tgid_vnr(tsk).\n\nThis seem to be the only mistake of that kind.\n\nSigned-off-by: Pavel Emelyanov \u003cxemul@openvz.org\u003e\nCc: \"Eric W.

In the\nprocess of doing that, it also provides infrastructure for keeping track of\nthe number of writers to any given mount.\n\nThis has a number of uses. It allows chroots to have parts of filesystems\nwritable.

With the option of\nbacking ipc shared memory with either hugetlbfs or ordinary shared memory\nthe problems got worse. With the added support for ipc namespaces things\nbehaved so unexpected that we now have several bad namespace reference\ncounting bugs when using what appears at first glance to be a reasonable\nidiom.\n\nSo to attack these problems and hopefully make the code more maintainable\nthis patch simply uses the files provided by other parts of the kernel and\nbuilds it\u0027s own files out of them. The shm files are allocated in do_shmat\nand freed when their reference count drops to zero with their last unmap.\nThe file and vm operations that we don\u0027t want to implement or we don\u0027t\nimplement completely we just delegate to the operations of our backing\nfile.\n\nThis means that we now get an accurate shm_nattch count for we have a\nhugetlbfs inode for backing store, and the shm accounting of last attach\nand last detach time work as well.\n\nThis means that getting a reference to the ipc namespace when we create the\nfile and dropping the referenece in the release method is now safe and\ncorrect.\n\nThis means we no longer need a special case for clearing VM_MAYWRITE\nas our file descriptor now only has write permissions when we have\nrequested write access when calling shmat. Although VM_SHARED is now\ncleared as well which I believe is harmless and is mostly likely a\nminor bug fix.\n\nBy using the same set of operations for both the hugetlb case and regular\nshared memory case shmdt is not simplified and made slightly more correct\nas now the test \"vma-\u003evm_ops \u003d\u003d \u0026shm_vm_ops\" is 100% accurate in spotting\nall shared memory regions generated from sysvipc shared memory.\n\nSigned-off-by: Eric W.

This governs auto-release of the structure upon execution.\n\nOrdinarily, the work queue executor would release the work_struct for further\nscheduling or deallocation by clearing the pending bit prior to jumping to the\nwork function.

This is a\nproblem if the auxiliary data is taken away (as done by the last patch).\n\nHowever, if the pending bit is *not* cleared before jumping to the work\nfunction, then the work function *may* access the work_struct and its container\nwith no problems. But then the work function must itself release the\nwork_struct by calling work_release().\n\nIn most cases, automatic release is fine, so this is the default.
