In\ntwo places.\n\nThe big constant that is being xor\u0027ed is GOLDEN_RATIO_PRIME, which is a\nfairly random-looking number that is designed to be *multiplied* with so\nthat the bits get spread out over a whole long-word.\n\nBut xor\u0027ing with it is insane. It doesn\u0027t really even change the hash -\nit really only shifts the hash around in the hash table. To make\nmatters worse, the insane big constant is different on 32-bit and 64-bit\nbuilds, even though the name hash bits we use are always 32-bit (and the\nbits from the pointer we mix in effectively are too).\n\nIt\u0027s all total voodoo programming, in other words.\n\nNow, some testing and analysis of the hash chains shows that the rest of\nthe hash function seems to be fairly good. It does pick the right bits\nof the parent dentry pointer, for example, and while it\u0027s generally a\nbad idea to use an xor to mix down the upper bits (because if there is a\nrepeating pattern, the xor can cause \"destructive interference\"), it\nseems to not have been a disaster.\n\nFor example, replacing the hash with the normal \"hash_long()\" code (that\nuses the GOLDEN_RATIO_PRIME constant correctly, btw) actually just makes\nthe hash worse. The hand-picked hash knew which bits of the pointer had\nthe highest entropy, and hash_long() ends up mixing bits less optimally\nat least in some trivial tests.\n\nSo the hash function overall seems fine, it just has that really odd\n\"shift result around by a constant xor\".\n\nSo get rid of the silly xor, and replace the down-mixing of the bits\nwith an add instead of an xor that tends to not have the same kind of\ndestructive interference issues. Some stats on the resulting hash\nchains shows that they look statistically identical before and after,\nbut the code is simpler and no longer makes you go \"WTF?\".\n\nAlso, the incoming hash really is just \"unsigned int\", not a long, and\nthere\u0027s no real point to worry about the high 26 bits of the dentry\npointer for the 64-bit case, because they are all going to be identical\nanyway.\n\nSo also change the hashing to be done in the more natural \u0027unsigned int\u0027\nthat is the real size of the actual hashed data anyway.\n\nSigned-off-by: Linus Torvalds \u003ctorvalds@linux-foundation.org\u003e\n" }, { "commit": "9521d830b6341d1887dcfc2aebde23fbfa5f1473", "tree": "db6b03aaca5ca4a254912ae1a7f3e5e89ee182e4", "parents": [ "bea95c152dee1791dd02cbc708afbb115bb00f9a", "c31a94570552dcaa517c4f7a043ffd28835016be" ], "author": { "name": "Ingo Molnar", "email": "mingo@kernel.org", "time": "Mon Mar 19 20:14:46 2012 +0100" }, "committer": { "name": "Ingo Molnar", "email": "mingo@kernel.org", "time": "Mon Mar 19 20:14:46 2012 +0100" }, "message": "Merge tag \u0027perf-core-for-mingo\u0027 of git://git.kernel.org/pub/scm/linux/kernel/git/acme/linux into perf/core\n\nFixes for the last batch from Namhyung and the initial GTK report browser\nfrom Pekka.\n\nSigned-off-by: Arnaldo Carvalho de Melo \u003cacme@redhat.com\u003e\n" }, { "commit": "c31a94570552dcaa517c4f7a043ffd28835016be", "tree": "db6b03aaca5ca4a254912ae1a7f3e5e89ee182e4", "parents": [ "fde0eeaba7fe18dfd2ee6142fb562123e510ef84" ], "author": { "name": "Pekka Enberg", "email": "penberg@kernel.org", "time": "Mon Mar 19 15:13:29 2012 -0300" }, "committer": { "name": "Arnaldo Carvalho de Melo", "email": "acme@redhat.com", "time": "Mon Mar 19 15:13:29 2012 -0300" }, "message": "perf report: Add a simple GTK2-based \u0027perf report\u0027 browser\n\nThis patch adds a simple GTK2-based browser to \u0027perf report\u0027 that\u0027s\nbased on the TTY-based browser in builtin-report.c.\n\nTo launch \"perf report\" using the new GTK interface just type:\n\n $ perf report --gtk\n\nThe interface is somewhat limited in features at the moment:\n\n -

results in SEGV\n\nI have a workload where perf top scribbles over the stack and we SEGV.\nWhat makes it interesting is that an snprintf is causing this.\n\nThe workload is a c++ gem that has method names over 3000 characters\nlong, but snprintf is designed to avoid overrunning buffers. So what\nwent wrong?\n\nThe problem is we assume snprintf returns the number of characters\nwritten:\n\n ret +\u003d repsep_snprintf(bf + ret, size - ret, \"[%c] \", self-\u003elevel);\n...\n ret +\u003d repsep_snprintf(bf + ret, size - ret, \"%s\", self-\u003ems.sym-\u003ename);\n\nUnfortunately this is not how snprintf works. snprintf returns the\nnumber of characters that would have been written if there was enough\nspace. In the above case, if the first snprintf returns a value larger\nthan size, we pass a negative size into the second snprintf and happily\nscribble over the stack. If you have 3000 character c++ methods thats a\nlot of stack to trample.\n\nThis patch fixes repsep_snprintf by clamping the value at size - 1 which\nis the maximum snprintf can write before adding the NULL terminator.\n\nI get the sinking feeling that there are a lot of other uses of snprintf\nthat have this same bug, we should audit them all.\n\nCc: David Ahern \u003cdsahern@gmail.com\u003e\nCc: Eric B Munson \u003cemunson@mgebm.net\u003e\nCc: Frederic Weisbecker \u003cfweisbec@gmail.com\u003e\nCc: Ingo Molnar \u003cmingo@elte.hu\u003e\nCc: Paul Mackerras \u003cpaulus@samba.org\u003e\nCc: Peter Zijlstra \u003cpeterz@infradead.org\u003e\nCc: Yanmin Zhang \u003cyanmin_zhang@linux.intel.com\u003e\nCc: stable@kernel.org\nLink: http://lkml.kernel.org/r/20120307114249.44275ca3@kryten\nSigned-off-by: Anton Blanchard \u003canton@samba.org\u003e\nSigned-off-by: Arnaldo Carvalho de Melo \u003cacme@redhat.com\u003e\n" }, { "commit": "ff8c1474cc2f5e11414c71ec4d739c18e6e669c0", "tree": "d498e6e97243a25d20100b9c5a1cee8c73920fb7", "parents": [ "ea5f4db8ece896c2ab9eafa0924148a2596c52e4" ], "author": { "name": "Xiaotian Feng", "email": "xtfeng@gmail.com", "time": "Wed Mar 14 15:34:48 2012 +0100" }, "committer": { "name": "Jens Axboe", "email": "axboe@kernel.dk", "time": "Wed Mar 14 15:34:48 2012 +0100" }, "message": "block: fix ioc leak in put_io_context\n\nWhen put_io_context is called, if ioc-\u003eicq_list is empty and refcount\nis 1, kernel will not free the ioc.\n\nThis is caught by following kmemleak:\n\nunreferenced object 0xffff880036349fe0 (size 216):\n comm \"sh\", pid 2137, jiffies 4294931140 (age 290579.412s)\n hex dump (first 32 bytes):\n 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 ................\n 01 00 01 00 ad 4e ad de ff ff ff ff 00 00 00 00 .....N..........\n backtrace:\n [\u003cffffffff8169f926\u003e] kmemleak_alloc+0x26/0x50\n [\u003cffffffff81195a9c\u003e] kmem_cache_alloc_node+0x1cc/0x2a0\n [\u003cffffffff81356b67\u003e] create_io_context_slowpath+0x27/0x130\n [\u003cffffffff81356d2b\u003e] get_task_io_context+0xbb/0xf0\n [\u003cffffffff81055f0e\u003e] copy_process+0x188e/0x18b0\n [\u003cffffffff8105609b\u003e] do_fork+0x11b/0x420\n [\u003cffffffff810247f8\u003e] sys_clone+0x28/0x30\n [\u003cffffffff816d3373\u003e] stub_clone+0x13/0x20\n [\u003cffffffffffffffff\u003e] 0xffffffffffffffff\n\nioc should be freed if ioc-\u003eicq_list is empty.\nSigned-off-by: Xiaotian Feng \u003cdannyfeng@tencent.com\u003e\nAcked-by: Vivek Goyal \u003cvgoyal@redhat.com\u003e\nAcked-by: Tejun Heo \u003ctj@kernel.org\u003e\nSigned-off-by: Jens Axboe \u003caxboe@kernel.dk\u003e\n" }, { "commit": "37d73998920859784e6504462a2fd5f52cc08051", "tree": "907bbfb570241027762c1b3f20a95b9cd8a191f9", "parents": [ "fa73dc9400516945bcbae8d98c23393bcefe1440" ], "author": { "name": "Jiri Olsa", "email": "jolsa@redhat.com", "time": "Wed Mar 14 00:03:02 2012 +0100" }, "committer": { "name": "Steven Rostedt", "email": "rostedt@goodmis.org", "time": "Wed Mar 14 08:47:58 2012 -0400" }, "message": "perf: Add ifdef to remove unused enum switch warnings\n\nFix for unused symbols in switch warnings.\n\nLink: http://lkml.kernel.org/r/20120313230302.GA1514@m.redhat.com\n\nCc: Mark Brown \u003cbroonie@opensource.wolfsonmicro.com\u003e\nCc: Frederic Weisbecker \u003cfweisbec@gmail.com\u003e\nCc: Ingo Molnar \u003cmingo@redhat.com\u003e\nSigned-off-by: Jiri Olsa \u003cjolsa@redhat.com\u003e\nSigned-off-by: Steven Rostedt \u003crostedt@goodmis.org\u003e\n" } ], "next": "7140ea1980f2fae9c7aaeac5f6b35317e1389ee6" }
