The simplified semantics for container-init are:\n\n\t- container-init must never be terminated by a signal from a\n\t descendant process.\n\n\t- container-init must never be immune to SIGKILL from an ancestor\n\t namespace (so a process in parent namespace must always be able\n\t to terminate a descendant container).\n\n\t- container-init may be immune to unhandled fatal signals (like\n\t SIGUSR1) even if they are from ancestor namespace. SIGKILL/SIGSTOP\n\t are the only reliable signals to a container-init from ancestor\n\t namespace.\n\nThis patch:\n\nBased on an earlier patch submitted by Oleg Nesterov and comments from\nRoland McGrath (http://lkml.org/lkml/2008/11/19/258).\n\nThe handler parameter is currently unused in the tracehook functions.\nBesides, the tracehook functions are called with siglock held, so the\nfunctions can check the handler if they later need to.\n\nRemoving the parameter simiplifies changes to sig_ignored() in a follow-on\npatch.\n\nSigned-off-by: Sukadev Bhattiprolu \u003csukadev@linux.vnet.ibm.com\u003e\nAcked-by: Roland McGrath \u003croland@redhat.com\u003e\nSigned-off-by: Oleg Nesterov \u003coleg@tv-sign.ru\u003e\nCc: \"Eric W.

By this, scanning\n\t css under root can be written without locks.\n\t ex)\n\t do {\n\t\trcu_read_lock();\n\t\tnext \u003d cgroup_get_next(subsys, id, root, \u0026found);\n\t\t/* check sanity of next here */\n\t\tcss_tryget();\n\t\trcu_read_unlock();\n\t\tid \u003d found + 1\n\t } while(...)\n\nCharacteristics:\n\t- Each css has unique ID under subsys.\n\t- Lifetime of ID is controlled by subsys.\n\t- css ID contains \"ID\" and \"Depth in hierarchy\" and stack of hierarchy\n\t- Allowed ID is 1-65535, ID 0 is UNUSED ID.\n\nDesign Choices:\n\t- scan-by-ID v.s. scan-by-tree-walk.\n\t As /proc\u0027s pid scan does, scan-by-ID is robust when scanning is done\n\t by following kind of routine.\n\t scan -\u003e rest a while(release a lock) -\u003e conitunue from interrupted\n\t memcg\u0027s hierarchical reclaim does this.\n\n\t- When subsys-\u003euse_id is set, # of css in the system is limited to\n\t 65535.\n\n[bharata@linux.vnet.ibm.com: remove rcu_read_lock() from css_get_next()]\nSigned-off-by: KAMEZAWA Hiroyuki \u003ckamezawa.hiroyu@jp.fujitsu.com\u003e\nAcked-by: Paul Menage \u003cmenage@google.com\u003e\nCc: Li Zefan \u003clizf@cn.fujitsu.com\u003e\nCc: Balbir Singh \u003cbalbir@in.ibm.com\u003e\nCc: Daisuke Nishimura \u003cnishimura@mxp.nes.nec.co.jp\u003e\nSigned-off-by: Bharata B Rao \u003cbharata@linux.vnet.ibm.com\u003e\nSigned-off-by: Andrew Morton \u003cakpm@linux-foundation.org\u003e\nSigned-off-by: Linus Torvalds \u003ctorvalds@linux-foundation.org\u003e\n" }, { "commit": "313e924c0852943e67335fad9d2608701f0dfe8e", "tree": "fa4c3f65a7ed6edea52ae78b012138ebab1420c3", "parents": [ "d20a390a0ee2bf2f692c539c6ce1c829e1080bb5" ], "author": { "name": "Grzegorz Nosek", "email": "root@localdomain.pl", "time": "Thu Apr 02 16:57:23 2009 -0700" }, "committer": { "name": "Linus Torvalds", "email": "torvalds@linux-foundation.org", "time": "Thu Apr 02 19:04:53 2009 -0700" }, "message": "cgroups: relax ns_can_attach checks to allow attaching to grandchild cgroups\n\nThe ns_proxy cgroup allows moving processes to child cgroups only one\nlevel deep at a time.

So the\nonly choice epoll has (not being able to call f_op-\u003epoll() from inside the\ncallback), is to add the file* to a ready-list and resolve the real events\nlater on, at epoll_wait() (or its own f_op-\u003epoll()) time. This can cause\nspurious wakeups, since the wake_up() itself might be for an event the\ncaller is not interested into.\n\nThe rate of these spurious wakeup can be pretty high in case of many\nnetwork sockets being monitored.\n\nBy allowing devices to report the events the wakeups refer to (at least\nthe two major classes - POLLIN/POLLOUT), we are able to spare useless\nwakeups by proper handling inside the epoll\u0027s poll callback.\n\nEpoll will have in any case to call f_op-\u003epoll() on the file* later on,\nsince the change to be done in order to have the full event set sent via\nwakeup, is too invasive for the way our f_op-\u003epoll() system works (the\nfull event set is calculated inside the poll function - there are too many\nof them to even start thinking the change - also poll/select would need\nchange too).\n\nEpoll is changed in a way that both devices which send event hints, and\nthe ones that don\u0027t, are correctly handled. The former will gain some\nefficiency though.\n\nAs a general rule for devices, would be to add an event mask by using\nkey-aware wakeup macros, when making up poll wait queues. I tested it\n(together with the epoll\u0027s poll fix patch Andrew has in -mm) and wakeups\nfor the supported devices are correctly filtered.\n\nTest program available here:\n\nhttp://www.xmailserver.org/epoll_test.c\n\nThis patch:\n\nNothing revolutionary here.

I\nprepared this patch for 2.6.29, but the merge window arrived before I\u0027d\ncompleted gathering statistics to justify sending it in.\n\nThen while comparing SLQB against SLUB, running SLUB on a laptop I\u0027d\nhabitually used with SLAB, I found SLUB to run my tmpfs kbuild swapping\ntests five times slower than SLAB or SLQB - other machines slower too, but\nnowhere near so bad. Simpler \"cp -a\" swapping tests showed the same.\n\nslub_max_order\u003d0 brings sanity to all, but heavy swapping is too far from\nnormal to justify such a tuning. The crucial factor on that laptop turns\nout to be that I\u0027m using an SD card for swap. What happens is this:\n\nBy default, SLUB uses order-2 pages for shmem_inode_cache (and many other\nfs inodes), so creating tmpfs files under memory pressure brings lumpy\nreclaim into play. One subpage of the order is chosen from the bottom of\nthe LRU as usual, then the other three picked out from their random\npositions on the LRUs.\n\nIn a tmpfs load, many of these pages will be ones which already passed\nthrough shmem_writepage, so already have swap allocated. And though their\noffsets on swap were probably allocated sequentially, now that the pages\nare picked off at random, their swap offsets are scattered.\n\nBut the flash storage on the SD card is very sensitive to having its\nwrites merged: once swap is written at scattered offsets, performance\nfalls apart. Rotating disk seeks increase too, but less disastrously.\n\nSo: stop giving shmem/tmpfs pages a second pass around the LRU, write them\nout to swap as soon as their swap has been allocated.\n\nIt\u0027s surely possible to devise an artificial load which runs faster the\nold way, one whose sizing is such that the tmpfs pages on their second\npass are the ones that are wanted again, and other pages not.\n\nBut I\u0027ve not yet found such a load: on all machines, under the loads I\u0027ve\ntried, immediate swap_writepage speeds up shmem swapping: especially when\nusing the SLUB allocator (and more effectively than slub_max_order\u003d0), but\nalso with the others; and it also reduces the variance between runs. How\nmuch faster varies widely: a factor of five is rare, 5% is common.\n\nOne load which might have suffered: imagine a swapping shmem load in a\nlimited mem_cgroup on a machine with plenty of memory. Before 2.6.29 the\nswapcache was not charged, and such a load would have run quickest with\nthe shmem swapcache never written to swap.
