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.

The use of this errcode in\ncontainer_of() may alter this errcode, and we don\u0027t want this.\n\nAnd in xxx_exit_ns, the pointer return by idr_find is of type \u0027struct\nkern_ipc_per\u0027...\n\nToday, the code will work as is because the member used in these\ncontainer_of() is the first member of its container (offset \u003d\u003d 0), the\nerrcode isn\u0027t changed then. But in the general case, we can\u0027t count on\nthis assumption and this may lead later to a real bug if we don\u0027t correct\nthis.\n\nAgain, the proposed solution is simple and correct.

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 patch introduces helper routines for\nsys_{msgrcv,msgsnd} as below:\n\ndo_msgsnd() : Accepts the mtype and user space ptr to the buffer along with\nthe msqid and msgflg.\n\ndo_msgrcv() : Accepts a kernel space ptr to mtype and a userspace ptr to\nthe buffer. The mtype has to be copied back the user space msgbuf by the\ncaller.\n\nThese changes avoid the need to allocate the msgsize on the userspace (\nthus removing the size limt ) and the overhead of an extra copy_in_user().\n\nSigned-off-by: Suzuki K P \u003csuzuki@in.ibm.com\u003e\nCc: Arnd Bergmann \u003carnd@arndb.de\u003e\nCc: \"David S.

For most filesystems, this should be done with simple_set_mnt()\nwhich will set the superblock pointer and then set the root dentry to the\nsuperblock\u0027s s_root (as per the old default behaviour).\n\nThe get_sb() op now returns an integer as there\u0027s now no need to return the\nsuperblock pointer.\n\nThis patch permits a superblock to be implicitly shared amongst several mount\npoints, such as can be done with NFS to avoid potential inode aliasing. In\nsuch a case, simple_set_mnt() would not be called, and instead the mnt_root\nand mnt_sb would be set directly.\n\nThe patch also makes the following changes:\n\n (*) the get_sb_*() convenience functions in the core kernel now take a vfsmount\n pointer argument and return an integer, so most filesystems have to change\n very little.\n\n (*) If one of the convenience function is not used, then get_sb() should\n normally call simple_set_mnt() to instantiate the vfsmount.

It wasn\u0027t being\n set and when audit_ipc_obj() is called from ipcperms(), the\n information isn\u0027t available. If we want the information in the IPC\n record, more extensive changes will be necessary.
