This permits a key type\n to intercept requests at the point /sbin/request-key is about to be\n spawned and do something else with them - passing them over the\n rpc_pipefs files or netlink sockets for instance.\n\n The uninstantiated key, the authorisation key and the intended operation\n name are passed to the method.\n\n (2) The callout_info is no longer passed as an argument to /sbin/request-key\n to prevent unauthorised viewing of this data using ps or by looking in\n /proc/pid/cmdline.\n\n This means that the old /sbin/request-key program will not work with the\n patched kernel as it will expect to see an extra argument that is no\n longer there.\n\n A revised keyutils package will be made available tomorrow.\n\n (3) The callout_info is now attached to the authorisation key. Reading this\n key will retrieve the information.\n\n (4) A new field has been added to the task_struct. This holds the\n authorisation key currently active for a thread. Searches now look here\n for the caller\u0027s set of keys rather than looking for an auth key in the\n lowest level of the session keyring.\n\n This permits a thread to be servicing multiple requests at once and to\n switch between them. Note that this is per-thread, not per-process, and\n so is usable in multithreaded programs.\n\n The setting of this field is inherited across fork and exec.\n\n (5) A new keyctl function (KEYCTL_ASSUME_AUTHORITY) has been added that\n permits a thread to assume the authority to deal with an uninstantiated\n key. Assumption is only permitted if the authorisation key associated\n with the uninstantiated key is somewhere in the thread\u0027s keyrings.\n\n This function can also clear the assumption.\n\n (6) A new magic key specifier has been added to refer to the currently\n assumed authorisation key (KEY_SPEC_REQKEY_AUTH_KEY).\n\n (7) Instantiation will only proceed if the appropriate authorisation key is\n assumed first. The assumed authorisation key is discarded if\n instantiation is successful.\n\n (8) key_validate() is moved from the file of request_key functions to the\n file of permissions functions.\n\n (9) The documentation is updated.\n\nFrom: \u003cValdis.Kletnieks@vt.edu\u003e\n\n Build fix.\n\nSigned-off-by: David Howells \u003cdhowells@redhat.com\u003e\nCc: Trond Myklebust \u003ctrond.myklebust@fys.uio.no\u003e\nCc: Alexander Zangerl \u003caz@bond.edu.au\u003e\nSigned-off-by: Andrew Morton \u003cakpm@osdl.org\u003e\nSigned-off-by: Linus Torvalds \u003ctorvalds@osdl.org\u003e\n" }, { "commit": "017679c4d45783158dba1dd6f79e712c22bb3d9a", "tree": "a536f0b581eacd88a64077f5ff15b29d23fc6405", "parents": [ "cd140a5c1f456f50897af4a2e9a23d228a5fe719" ], "author": { "name": "David Howells", "email": "dhowells@redhat.com", "time": "Sun Jan 08 01:02:43 2006 -0800" }, "committer": { "name": "Linus Torvalds", "email": "torvalds@g5.osdl.org", "time": "Sun Jan 08 20:13:53 2006 -0800" }, "message": "[PATCH] keys: Permit key expiry time to be set\n\nAdd a new keyctl function that allows the expiry time to be set on a key or\nremoved from a key, provided the caller has attribute modification access.\n\nSigned-off-by: David Howells \u003cdhowells@redhat.com\u003e\nCc: Trond Myklebust \u003ctrond.myklebust@fys.uio.no\u003e\nCc: Alexander Zangerl \u003caz@bond.edu.au\u003e\nSigned-off-by: Andrew Morton \u003cakpm@osdl.org\u003e\nSigned-off-by: Linus Torvalds \u003ctorvalds@osdl.org\u003e\n" }, { "commit": "4a30131e7dbb17e5fec6958bfac9da9aff1fa29b", "tree": "2ff6139b393a9a413e2ea4db4dd2d15eec2201f8", "parents": [ "788540141f4549637e89aadca6e25cf25eb53383" ], "author": { "name": "NeilBrown", "email": "neilb@suse.de", "time": "Sun Jan 08 01:02:39 2006 -0800" }, "committer": { "name": "Linus Torvalds", "email": "torvalds@g5.osdl.org", "time": "Sun Jan 08 20:13:52 2006 -0800" }, "message": "[PATCH] Fix some problems with truncate and mtime semantics.\n\nSUS requires that when truncating a file to the size that it currently\nis:\n truncate and ftruncate should NOT modify ctime or mtime\n O_TRUNC SHOULD modify ctime and mtime.\n\nCurrently mtime and ctime are always modified on most local\nfilesystems (side effect of -\u003etruncate) or never modified (on NFS).\n\nWith this patch:\n ATTR_CTIME|ATTR_MTIME are sent with ATTR_SIZE precisely when\n an update of these times is required whether size changes or not\n (via a new argument to do_truncate).

The kernel maintains\ninternal state for each mempolicy, tracking what nodes are used for the\nMPOL_INTERLEAVE, MPOL_BIND or MPOL_PREFERRED policies.\n\nWhen a tasks cpuset memory placement changes, whether because the cpuset\nchanged, or because the task was attached to a different cpuset, then the\ntasks mempolicies have to be rebound to the new cpuset placement, so as to\npreserve the cpuset-relative numbering of the nodes in that policy.\n\nAn earlier fix handled such mempolicy rebinding for mempolicies attached to a\ntask.\n\nThis fix rebinds mempolicies attached to vma\u0027s (address ranges in a tasks\naddress space.) Due to the need to hold the task-\u003emm-\u003emmap_sem semaphore while\nupdating vma\u0027s, the rebinding of vma mempolicies has to be done when the\ncpuset memory placement is changed, at which time mmap_sem can be safely\nacquired. The tasks mempolicy is rebound later, when the task next attempts\nto allocate memory and notices that its task-\u003ecpuset_mems_generation is\nout-of-date with its cpusets mems_generation.\n\nBecause walking the tasklist to find all tasks attached to a changing cpuset\nrequires holding tasklist_lock, a spinlock, one cannot update the vma\u0027s of the\naffected tasks while doing the tasklist scan. In general, one cannot acquire\na semaphore (which can sleep) while already holding a spinlock (such as\ntasklist_lock). So a list of mm references has to be built up during the\ntasklist scan, then the tasklist lock dropped, then for each mm, its mmap_sem\nacquired, and the vma\u0027s in that mm rebound.\n\nOnce the tasklist lock is dropped, affected tasks may fork new tasks, before\ntheir mm\u0027s are rebound. A kernel global \u0027cpuset_being_rebound\u0027 is set to\npoint to the cpuset being rebound (there can only be one; cpuset modifications\nare done under a global \u0027manage_sem\u0027 semaphore), and the mpol_copy code that\nis used to copy a tasks mempolicies during fork catches such forking tasks,\nand ensures their children are also rebound.\n\nWhen a task is moved to a different cpuset, it is easier, as there is only one\ntask involved. It\u0027s mm-\u003evma\u0027s are scanned, using the same\nmpol_rebind_policy() as used above.\n\nIt may happen that both the mpol_copy hook and the update done via the\ntasklist scan update the same mm twice. This is ok, as the mempolicies of\neach vma in an mm keep track of what mems_allowed they are relative to, and\nsafely no-op a second request to rebind to the same nodes.\n\nSigned-off-by: Paul Jackson \u003cpj@sgi.com\u003e\nSigned-off-by: Andrew Morton \u003cakpm@osdl.org\u003e\nSigned-off-by: Linus Torvalds \u003ctorvalds@osdl.org\u003e\n" }, { "commit": "202f72d5d1b5c2c084f63ef996c736d208b447b5", "tree": "f50551f9588f9090fee17130614e17a2dd64c656", "parents": [ "74cb21553f4bf244185b9bec4c26e4e3169ad55e" ], "author": { "name": "Paul Jackson", "email": "pj@sgi.com", "time": "Sun Jan 08 01:01:57 2006 -0800" }, "committer": { "name": "Linus Torvalds", "email": "torvalds@g5.osdl.org", "time": "Sun Jan 08 20:13:44 2006 -0800" }, "message": "[PATCH] cpuset: number_of_cpusets optimization\n\nEasy little optimization hack to avoid actually having to call\ncpuset_zone_allowed() and check mems_allowed, in the main page allocation\nroutine, __alloc_pages().

This means that the\nvirtual addresses that the process sees do not change. However, the system\nrearranges the physical location of those pages.\n\nThe main intent of page migration patches here is to reduce the latency of\nmemory access by moving pages near to the processor where the process\naccessing that memory is running.\n\nThe patchset allows a process to manually relocate the node on which its\npages are located through the MF_MOVE and MF_MOVE_ALL options while\nsetting a new memory policy.\n\nThe pages of process can also be relocated from another process using the\nsys_migrate_pages() function call. Requires CAP_SYS_ADMIN. The migrate_pages\nfunction call takes two sets of nodes and moves pages of a process that are\nlocated on the from nodes to the destination nodes.\n\nManual migration is very useful if for example the scheduler has relocated a\nprocess to a processor on a distant node. A batch scheduler or an\nadministrator can detect the situation and move the pages of the process\nnearer to the new processor.\n\nsys_migrate_pages() could be used on non-numa machines as well, to force all\nof a particualr process\u0027s pages out to swap, if someone thinks that\u0027s useful.\n\nLarger installations usually partition the system using cpusets into sections\nof nodes. Paul has equipped cpusets with the ability to move pages when a\ntask is moved to another cpuset. This allows automatic control over locality\nof a process. If a task is moved to a new cpuset then also all its pages are\nmoved with it so that the performance of the process does not sink\ndramatically (as is the case today).\n\nSwap migration works by simply evicting the page. The pages must be faulted\nback in. The pages are then typically reallocated by the system near the node\nwhere the process is executing.\n\nFor swap migration the destination of the move is controlled by the allocation\npolicy. Cpusets set the allocation policy before calling sys_migrate_pages()\nin order to move the pages as intended.\n\nNo allocation policy changes are performed for sys_migrate_pages(). This\nmeans that the pages may not faulted in to the specified nodes if no\nallocation policy was set by other means. The pages will just end up near the\nnode where the fault occurred.\n\nThere\u0027s another patch series in the pipeline which implements \"direct\nmigration\".\n\nThe direct migration patchset extends the migration functionality to avoid\ngoing through swap. The destination node of the relation is controllable\nduring the actual moving of pages. The crutch of using the allocation policy\nto relocate is not necessary and the pages are moved directly to the target.\nIts also faster since swap is not used.\n\nAnd sys_migrate_pages() can then move pages directly to the specified node.\nImplement functions to isolate pages from the LRU and put them back later.\n\nThis patch:\n\nAn earlier implementation was provided by Hirokazu Takahashi\n\u003ctaka@valinux.co.jp\u003e and IWAMOTO Toshihiro \u003ciwamoto@valinux.co.jp\u003e for the\nmemory hotplug project.\n\nFrom: Magnus\n\nThis breaks out isolate_lru_page() and putpack_lru_page().
