Such counters are then\n\u0027inherited\u0027 by all child tasks (be they fork()-ed or clone()-ed). These\ncounters get inherited through exec() boundaries as well (except through\nsetuid boundaries).\n\nThe counter values get added back to the parent counter(s) when the child\ntask(s) exit - much like stime/utime statistics are gathered. So inherited\ncounters are ideal to gather summary statistics about an application\u0027s\nbehavior via shell commands, without having to modify that application.\n\nThe timec.c command utilizes counter inheritance:\n\n http://redhat.com/~mingo/perfcounters/timec.c\n\nSample output:\n\n $ ./timec -e 1 -e 3 -e 5 ls -lR /usr/include/ \u003e/dev/null\n\n Performance counter stats for \u0027ls\u0027:\n\n 163516953 instructions\n 2295 cache-misses\n 2855182 branch-misses\n\nSigned-off-by: Ingo Molnar \u003cmingo@elte.hu\u003e\n" }, { "commit": "ee06094f8279e1312fc0a31591320cc7b6f0ab1e", "tree": "aecf8f2177b2398e4db8df68a9705009b31a8ef7", "parents": [ "9b194e831fb2c322ed81a373e49620f34edc2778" ], "author": { "name": "Ingo Molnar", "email": "mingo@elte.hu", "time": "Sat Dec 13 09:00:03 2008 +0100" }, "committer": { "name": "Ingo Molnar", "email": "mingo@elte.hu", "time": "Sun Dec 14 20:30:48 2008 +0100" }, "message": "perfcounters: restructure x86 counter math\n\nImpact: restructure code\n\nChange counter math from absolute values to clear delta logic.\n\nWe try to extract elapsed deltas from the raw hw counter - and put\nthat into the generic counter.\n\nSigned-off-by: Ingo Molnar \u003cmingo@elte.hu\u003e\n" }, { "commit": "92bf73e90a35d40ebc1446488218f03833b36f86", "tree": "8aaae58fcb7f3e06e63a5214f910acf47f4cc9d6", "parents": [ "447557ac7ce120306b4a31d6003faef39cb1bf14", "915b0d0104b72fd36af088ba4b11b5690bc96a6c" ], "author": { "name": "Ingo Molnar", "email": "mingo@elte.hu", "time": "Fri Dec 12 12:00:02 2008 +0100" }, "committer": { "name": "Ingo Molnar", "email": "mingo@elte.hu", "time": "Fri Dec 12 12:00:14 2008 +0100" }, "message": "Merge branch \u0027x86/irq\u0027 into perfcounters/core\n\n( with manual semantic merge of arch/x86/kernel/cpu/perf_counter.c )\n" }, { "commit": "fd10902797fc9d6abaf55d9c2e3c6698c90b10c7", "tree": "0bc15b8b967e6f0973387e7c81f5b0dc9ce44e75", "parents": [ "5b3eec0c80038c8739ccd465b897a35c0dff1cc4", "8b1fae4e4200388b64dd88065639413cb3f1051c" ], "author": { "name": "Ingo Molnar", "email": "mingo@elte.hu", "time": "Fri Dec 12 11:59:39 2008 +0100" }, "committer": { "name": "Ingo Molnar", "email": "mingo@elte.hu", "time": "Fri Dec 12 11:59:39 2008 +0100" }, "message": "Merge commit \u0027v2.6.28-rc8\u0027 into x86/irq\n" }, { "commit": "6a930700c8b655a9e25e42fc4adc0b225ebbcefc", "tree": "5b6aa07d2734f43d0c5bc7d97aebe256e6d86fa8", "parents": [ "1d1c7ddbfab358445a542715551301b7fc363e28" ], "author": { "name": "Ingo Molnar", "email": "mingo@elte.hu", "time": "Thu Dec 11 15:17:03 2008 +0100" }, "committer": { "name": "Ingo Molnar", "email": "mingo@elte.hu", "time": "Thu Dec 11 15:45:56 2008 +0100" }, "message": "perf counters: clean up state transitions\n\nImpact: cleanup\n\nIntroduce a proper enum for the 3 states of a counter:\n\n\tPERF_COUNTER_STATE_OFF\t\t\u003d -1\n\tPERF_COUNTER_STATE_INACTIVE\t\u003d 0\n\tPERF_COUNTER_STATE_ACTIVE\t\u003d 1\n\nand rename counter-\u003eactive to counter-\u003estate and propagate the\nchanges everywhere.\n\nSigned-off-by: Ingo Molnar \u003cmingo@elte.hu\u003e\n" }, { "commit": "1d1c7ddbfab358445a542715551301b7fc363e28", "tree": "d4421834d109b206f39c2019ea039fd42ed22e1d", "parents": [ "bae43c9945ebeef15e7952e317efb02393d3bfc7" ], "author": { "name": "Ingo Molnar", "email": "mingo@elte.hu", "time": "Thu Dec 11 14:59:31 2008 +0100" }, "committer": { "name": "Ingo Molnar", "email": "mingo@elte.hu", "time": "Thu Dec 11 15:45:55 2008 +0100" }, "message": "perf counters: add prctl interface to disable/enable counters\n\nAdd a way for self-monitoring tasks to disable/enable counters summarily,\nvia a prctl:\n\n\tPR_TASK_PERF_COUNTERS_DISABLE\t\t31\n\tPR_TASK_PERF_COUNTERS_ENABLE\t\t32\n\nSigned-off-by: Ingo Molnar \u003cmingo@elte.hu\u003e\n" }, { "commit": "bae43c9945ebeef15e7952e317efb02393d3bfc7", "tree": "78d12a494fa9c3f73e76e8d7895ceb94d48d517d", "parents": [ "01b2838c4298c5e0d30b4993c195ac34dd9df61e" ], "author": { "name": "Ingo Molnar", "email": "mingo@elte.hu", "time": "Thu Dec 11 14:03:20 2008 +0100" }, "committer": { "name": "Ingo Molnar", "email": "mingo@elte.hu", "time": "Thu Dec 11 15:45:54 2008 +0100" }, "message": "perf counters: implement PERF_COUNT_TASK_CLOCK\n\nImpact: add new perf-counter type\n\nThe \u0027task clock\u0027 counter counts the amount of time a task is executing,\nin nanoseconds.

It zeroes out counters on \"other\" cpus,\nwithout holding any locks which will prevent races agaist updates from\nthose other CPUS.\n\nThis patch reverts 1f7c14c62ce63805f9574664a6c6de3633d4a354. This means\nthat percpu_counter_sum_and_set() still has the race, but\npercpu_counter_sum() does not.\n\nNote that this is not a simple revert - ext4 has since started using\npercpu_counter_sum() for its dirty_blocks counter as well.\n\nNote that this revert patch changes percpu_counter_sum() semantics.\n\nBefore the patch, a call to percpu_counter_sum() will bring the counter\u0027s\ncentral counter mostly up-to-date, so a following percpu_counter_read()\nwill return a close value.\n\nAfter this patch, a call to percpu_counter_sum() will leave the counter\u0027s\ncentral accumulator unaltered, so a subsequent call to\npercpu_counter_read() can now return a significantly inaccurate result.\n\nIf there is any code in the tree which was introduced after\ne8ced39d5e8911c662d4d69a342b9d053eaaac4e was merged, and which depends\nupon the new percpu_counter_sum() semantics, that code will break.\n\nReported-by: Eric Dumazet \u003cdada1@cosmosbay.com\u003e\nCc: \"David S.

To\nsolve such problem, default limits are now imposed, and /proc based\nconfiguration has been introduced. A new directory has been created,\nnamed /proc/sys/fs/epoll/ and inside there, there are two configuration\npoints:\n\n max_user_instances \u003d Maximum number of devices - per user\n\n max_user_watches \u003d Maximum number of \"watched\" fds - per user\n\nThe current default for \"max_user_watches\" limits the memory used by epoll\nto store \"watches\", to 1/32 of the amount of the low RAM.

More details here:\nhttp://udrepper.livejournal.com/20407.html \"Secure File Descriptor Handling\",\nUlrich Drepper).\n\nThe other flag is SOCK_NONBLOCK, which causes the O_NONBLOCK flag\nto be enabled on the new open file description created by accept4().\n(This flag is merely a convenience, saving the use of additional calls\nfcntl(F_GETFL) and fcntl (F_SETFL) to achieve the same result.\n\nHere\u0027s a test program. Works on x86-32. Should work on x86-64, but\nI (mtk) don\u0027t have a system to hand to test with.\n\nIt tests accept4() with each of the four possible combinations of\nSOCK_CLOEXEC and SOCK_NONBLOCK set/clear in \u0027flags\u0027, and verifies\nthat the appropriate flags are set on the file descriptor/open file\ndescription returned by accept4().\n\nI tested Ulrich\u0027s patch in this thread by applying against 2.6.28-rc2,\nand it passes according to my test program.\n\n/* test_accept4.c\n\n Copyright (C) 2008, Linux Foundation, written by Michael Kerrisk\n \u003cmtk.manpages@gmail.com\u003e\n\n Licensed under the GNU GPLv2 or later.\n*/\n#define _GNU_SOURCE\n#include \u003cunistd.h\u003e\n#include \u003csys/syscall.h\u003e\n#include \u003csys/socket.h\u003e\n#include \u003cnetinet/in.h\u003e\n#include \u003cstdlib.h\u003e\n#include \u003cfcntl.h\u003e\n#include \u003cstdio.h\u003e\n#include \u003cstring.h\u003e\n\n#define PORT_NUM 33333\n\n#define die(msg) do { perror(msg); exit(EXIT_FAILURE); } while (0)\n\n/**********************************************************************/\n\n/* The following is what we need until glibc gets a wrapper for\n accept4() */\n\n/* Flags for socket(), socketpair(), accept4() */\n#ifndef SOCK_CLOEXEC\n#define SOCK_CLOEXEC O_CLOEXEC\n#endif\n#ifndef SOCK_NONBLOCK\n#define SOCK_NONBLOCK O_NONBLOCK\n#endif\n\n#ifdef __x86_64__\n#define SYS_accept4 288\n#elif __i386__\n#define USE_SOCKETCALL 1\n#define SYS_ACCEPT4 18\n#else\n#error \"Sorry -- don\u0027t know the syscall # on this architecture\"\n#endif\n\nstatic int\naccept4(int fd, struct sockaddr *sockaddr, socklen_t *addrlen, int flags)\n{\n printf(\"Calling accept4(): flags \u003d %x\", flags);\n if (flags !\u003d 0) {\n printf(\" (\");\n if (flags \u0026 SOCK_CLOEXEC)\n printf(\"SOCK_CLOEXEC\");\n if ((flags \u0026 SOCK_CLOEXEC) \u0026\u0026 (flags \u0026 SOCK_NONBLOCK))\n printf(\" \");\n if (flags \u0026 SOCK_NONBLOCK)\n printf(\"SOCK_NONBLOCK\");\n printf(\")\");\n }\n printf(\"\\n\");\n\n#if USE_SOCKETCALL\n long args[6];\n\n args[0] \u003d fd;\n args[1] \u003d (long) sockaddr;\n args[2] \u003d (long) addrlen;\n args[3] \u003d flags;\n\n return syscall(SYS_socketcall, SYS_ACCEPT4, args);\n#else\n return syscall(SYS_accept4, fd, sockaddr, addrlen, flags);\n#endif\n}\n\n/**********************************************************************/\n\nstatic int\ndo_test(int lfd, struct sockaddr_in *conn_addr,\n int closeonexec_flag, int nonblock_flag)\n{\n int connfd, acceptfd;\n int fdf, flf, fdf_pass, flf_pass;\n struct sockaddr_in claddr;\n socklen_t addrlen;\n\n printf(\"\u003d\u003d\u003d\u003d\u003d\u003d\u003d\u003d\u003d\u003d\u003d\u003d\u003d\u003d\u003d\u003d\u003d\u003d\u003d\u003d\u003d\u003d\u003d\u003d\u003d\u003d\u003d\u003d\u003d\u003d\u003d\u003d\u003d\u003d\u003d\u003d\u003d\u003d\u003d\\n\");\n\n connfd \u003d socket(AF_INET, SOCK_STREAM, 0);\n if (connfd \u003d\u003d -1)\n die(\"socket\");\n if (connect(connfd, (struct sockaddr *) conn_addr,\n sizeof(struct sockaddr_in)) \u003d\u003d -1)\n die(\"connect\");\n\n addrlen \u003d sizeof(struct sockaddr_in);\n acceptfd \u003d accept4(lfd, (struct sockaddr *) \u0026claddr, \u0026addrlen,\n closeonexec_flag | nonblock_flag);\n if (acceptfd \u003d\u003d -1) {\n perror(\"accept4()\");\n close(connfd);\n return 0;\n }\n\n fdf \u003d fcntl(acceptfd, F_GETFD);\n if (fdf \u003d\u003d -1)\n die(\"fcntl:F_GETFD\");\n fdf_pass \u003d ((fdf \u0026 FD_CLOEXEC) !\u003d 0) \u003d\u003d\n ((closeonexec_flag \u0026 SOCK_CLOEXEC) !\u003d 0);\n printf(\"Close-on-exec flag is %sset (%s); \",\n (fdf \u0026 FD_CLOEXEC) ?

That\u0027s fine if we have a hold on inode; however, for all\nother cases we need to make damn sure we don\u0027t race with umount. We can\n*NOT* just grab a reference to a watch - inotify_unmount_inodes() will\nhappily sail past it and we\u0027ll end with reference to inode potentially\noutliving its superblock.\n\nIdeally we just want to grab an active reference to superblock if we\ncan; that will make sure we won\u0027t go into inotify_umount_inodes() until\nwe are done. Cleanup is just deactivate_super().\n\nHowever, that leaves a messy case - what if we *are* racing with\numount() and active references to superblock can\u0027t be acquired anymore?\nWe can bump -\u003es_count, grab -\u003es_umount, which will almost certainly wait\nuntil the superblock is shut down and the watch in question is pining\nfor fjords. That\u0027s fine, but there is a problem - we might have hit the\nwindow between -\u003es_active getting to 0 / -\u003es_count - below S_BIAS (i.e.\nthe moment when superblock is past the point of no return and is heading\nfor shutdown) and the moment when deactivate_super() acquires\n-\u003es_umount.\n\nWe could just do drop_super() yield() and retry, but that\u0027s rather\nantisocial and this stuff is luser-triggerable. OTOH, having grabbed\n-\u003es_umount and having found that we\u0027d got there first (i.e. that\n-\u003es_root is non-NULL) we know that we won\u0027t race with\ninotify_umount_inodes().\n\nSo we could grab a reference to watch and do the rest as above, just\nwith drop_super() instead of deactivate_super(), right? Wrong. We had\nto drop ih-\u003emutex before we could grab -\u003es_umount. So the watch\ncould\u0027ve been gone already.\n\nThat still can be dealt with - we need to save watch-\u003ewd, do idr_find()\nand compare its result with our pointer. If they match, we either have\nthe damn thing still alive or we\u0027d lost not one but two races at once,\nthe watch had been killed and a new one got created with the same -\u003ewd\nat the same address. That couldn\u0027t have happened in inotify_destroy(),\nbut inotify_rm_wd() could run into that.

It is a global flag, and affects all ring buffers.\n\nThe buffers start out with tracing_on enabled.\n\nThere are now three flags that control recording into the buffers:\n\n tracing_on: which affects all ring buffer tracers.\n\n buffer-\u003erecord_disabled: which affects an allocated buffer, which may be set\n if an anomaly is detected, and tracing is disabled.\n\n cpu_buffer-\u003erecord_disabled: which is set by tracing_stop() or if an\n anomaly is detected. tracing_start can not reenable this if\n an anomaly occurred.\n\nThe userspace debugfs/tracing/tracing_enabled is implemented with\ntracing_stop() but the user space code can not enable it if the kernel\ncalled tracing_stop().\n\nUserspace can enable the tracing_on even if the kernel disabled it.\nIt is just a switch used to stop tracing if a condition was hit.\ntracing_on is not for protecting critical areas in the kernel nor is\nit for stopping tracing if an anomaly occurred. This is because userspace\ncan reenable it at any time.\n\nSide effect: With this patch, I discovered a dead variable in ftrace.c\n called tracing_on. This patch removes it.\n\nSigned-off-by: Steven Rostedt \u003csrostedt@redhat.com\u003e\n" }, { "commit": "2f96cb57cde9957bac0991c712068d29364b2ac9", "tree": "60e3f985b9e865f3a1fdda131599fa84159cc73e", "parents": [ "09eb3b5b1bcab7b25e9dd57e90ee9753adf7afe2", "2002c69595a092518107f7e3c1294c9710bc92ae" ], "author": { "name": "Linus Torvalds", "email": "torvalds@linux-foundation.org", "time": "Tue Nov 11 10:52:25 2008 -0800" }, "committer": { "name": "Linus Torvalds", "email": "torvalds@linux-foundation.org", "time": "Tue Nov 11 10:52:25 2008 -0800" }, "message": "Merge branch \u0027sched-fixes-for-linus\u0027 of git://git.kernel.org/pub/scm/linux/kernel/git/tip/linux-2.6-tip\n\n* \u0027sched-fixes-for-linus\u0027 of git://git.kernel.org/pub/scm/linux/kernel/git/tip/linux-2.6-tip:\n sched: release buddies on yield\n fix for account_group_exec_runtime(), make sure -\u003esignal can\u0027t be freed under rq-\u003elock\n sched: clean up debug info\n" }, { "commit": "0906dd9df2f79042cfa82d8388895be7cbe7a51b", "tree": "98344a1ecf258320008846434475e58c70f479c3", "parents": [ "8eb04cf3402c59e84af9d2e86149edb4044f9a9e" ], "author": { "name": "Alan Cox", "email": "alan@lxorguk.ukuu.org.uk", "time": "Tue Nov 11 14:51:23 2008 +0000" }, "committer": { "name": "Linus Torvalds", "email": "torvalds@linux-foundation.org", "time": "Tue Nov 11 09:30:23 2008 -0800" }, "message": "telephony: trivial: fix up email address\n\nSigned-off-by: Alan Cox \u003calan@redhat.com\u003e\nSigned-off-by: Linus Torvalds \u003ctorvalds@linux-foundation.org\u003e\n" }, { "commit": "0a4cf2c8786219b4871c37240ab9787a61d843ee", "tree": "a126516733f3a757711754bbac189417c79d8bcb", "parents": [ "4694516d1987303dd83bfd0efdd36fa5b65d701b", "df02c6ff2e3937379b31ea161b53229134fe92f7" ], "author": { "name": "Linus Torvalds", "email": "torvalds@linux-foundation.org", "time": "Tue Nov 11 09:20:29 2008 -0800" }, "committer": { "name": "Linus Torvalds", "email": "torvalds@linux-foundation.org", "time": "Tue Nov 11 09:20:29 2008 -0800" }, "message": "Merge git://git.kernel.org/pub/scm/linux/kernel/git/davem/net-2.6\n\n* git://git.kernel.org/pub/scm/linux/kernel/git/davem/net-2.6:\n dsa: fix master interface allmulti/promisc handling\n dsa: fix skb-\u003epkt_type when mac address of slave interface differs\n net: fix setting of skb-\u003etail in skb_recycle_check()\n net: fix /proc/net/snmp as memory corruptor\n mac80211: fix a buffer overrun in station debug code\n netfilter: payload_len is be16, add size of struct rather than size of pointer\n ipv6: fix ip6_mr_init error path\n [4/4] dca: fixup initialization dependency\n [3/4] I/OAT: fix async_tx.callback checking\n [2/4] I/OAT: fix dma_pin_iovec_pages() error handling\n [1/4] I/OAT: fix channel resources free for not allocated channels\n ssb: Fix DMA-API compilation for non-PCI systems\n SSB: hide empty sub menu\n vlan: Fix typos in proc output string\n [netdrvr] usb/hso: Cleanup rfkill error handling\n sfc: Correct address of gPXE boot configuration in EEPROM\n el3_common_init() should be __devinit, not __init\n hso: rfkill type should be WWAN\n mlx4_en: Start port error flow bug fix\n af_key: mark policy as dead before destroying\n" }, { "commit": "ad474caca3e2a0550b7ce0706527ad5ab389a4d4", "tree": "6d4e5cbcee3a85230317a33d66655ece0c873f5c", "parents": [ "5ac5c4d604bf894ef672a7971d03fefdc7ea7e49" ], "author": { "name": "Oleg Nesterov", "email": "oleg@redhat.com", "time": "Mon Nov 10 15:39:30 2008 +0100" }, "committer": { "name": "Ingo Molnar", "email": "mingo@elte.hu", "time": "Tue Nov 11 08:01:43 2008 +0100" }, "message": "fix for account_group_exec_runtime(), make sure -\u003esignal can\u0027t be freed under rq-\u003elock\n\nImpact: fix hang/crash on ia64 under high load\n\nThis is ugly, but the simplest patch by far.\n\nUnlike other similar routines, account_group_exec_runtime() could be\ncalled \"implicitly\" from within scheduler after exit_notify().
