He also\nsuggested using system call instead of /proc/\u003cpid\u003e/ interface, I decided to\nuse the latter continuously because adding new system call with pid argument\nwill give a big impact on the kernel.\n\nYou can access the per-process flags via /proc/\u003cpid\u003e/coredump_filter\ninterface. coredump_filter represents a bitmask of memory types, and if a bit\nis set, VMAs of corresponding memory type are written into a core file when\nthe process is dumped. The bitmask is inherited from the parent process when\na process is created.\n\nThe original purpose is to avoid longtime system slowdown when a number of\nprocesses which share a huge shared memory are dumped at the same time. To\nachieve this purpose, this patch series adds an ability to suppress dumping\nanonymous shared memory for specified processes. In this version, three other\nmemory types are also supported.\n\nHere are the coredump_filter bits:\n bit 0: anonymous private memory\n bit 1: anonymous shared memory\n bit 2: file-backed private memory\n bit 3: file-backed shared memory\n\nThe default value of coredump_filter is 0x3. This means the new core dump\nroutine has the same behavior as conventional behavior by default.\n\nIn this version, coredump_filter bits and mm.dumpable are merged into\nmm.flags, and it is accessed by atomic bitops.\n\nThe supported core file formats are ELF and ELF-FDPIC. ELF has been tested,\nbut ELF-FDPIC has not been built and tested because I don\u0027t have the test\nenvironment.\n\nThis patch limits a value of suid_dumpable sysctl to the range of 0 to 2.\n\nSigned-off-by: Hidehiro Kawai \u003chidehiro.kawai.ez@hitachi.com\u003e\nCc: Alan Cox \u003calan@lxorguk.ukuu.org.uk\u003e\nCc: David Howells \u003cdhowells@redhat.com\u003e\nCc: Hugh Dickins \u003chugh@veritas.com\u003e\nCc: Nick Piggin \u003cnickpiggin@yahoo.com.au\u003e\nSigned-off-by: Andrew Morton \u003cakpm@linux-foundation.org\u003e\nSigned-off-by: Linus Torvalds \u003ctorvalds@linux-foundation.org\u003e\n" }, { "commit": "bdf4c48af20a3b0f01671799ace345e3d49576da", "tree": "7c3b903d2de1cba6e212ad6f347bc8742b08035a", "parents": [ "b111757c50ee30dad162192df6168e270a90c252" ], "author": { "name": "Peter Zijlstra", "email": "a.p.zijlstra@chello.nl", "time": "Thu Jul 19 01:48:15 2007 -0700" }, "committer": { "name": "Linus Torvalds", "email": "torvalds@woody.linux-foundation.org", "time": "Thu Jul 19 10:04:45 2007 -0700" }, "message": "audit: rework execve audit\n\nThe purpose of audit_bprm() is to log the argv array to a userspace daemon at\nthe end of the execve system call.

The core dump will be\nwritten to the standard input of that program instead of to a file.\n\nThis is useful for having automatic core dump analysis without filling up\ndisks. The program can do some simple analysis and save only a summary of\nthe core dump.\n\nThe core dump proces will run with the privileges and in the name space of\nthe process that caused the core dump.\n\nI also increased the core pattern size to 128 bytes so that longer command\nlines fit.\n\nMost of the changes comes from allowing core dumps without seeks. They are\nfairly straight forward though.\n\nOne small incompatibility is that if someone had a core pattern previously\nthat started with \u0027|\u0027 they will get suddenly new behaviour. I think that\u0027s\nunlikely to be a real problem though.\n\nAdditional background:\n\n\u003e Very nice, do you happen to have a program that can accept this kind of\n\u003e input for crash dumps? I\u0027m guessing that the embedded people will\n\u003e really want this functionality.\n\nI had a cheesy demo/prototype. Basically it wrote the dump to a file again,\nran gdb on it to get a backtrace and wrote the summary to a shared directory.\nThen there was a simple CGI script to generate a \"top 10\" crashes HTML\nlisting.\n\nUnfortunately this still had the disadvantage to needing full disk space for a\ndump except for deleting it afterwards (in fact it was worse because over the\npipe holes didn\u0027t work so if you have a holey address map it would require\nmore space).\n\nFortunately gdb seems to be happy to handle /proc/pid/fd/xxx input pipes as\ncores (at least it worked with zsh\u0027s \u003d(cat core) syntax), so it would be\nlikely possible to do it without temporary space with a simple wrapper that\ncalls it in the right way. I ran out of time before doing that though.\n\nThe demo prototype scripts weren\u0027t very good. If there is really interest I\ncan dig them out (they are currently on a laptop disk on the desk with the\nlaptop itself being in service), but I would recommend to rewrite them for any\nserious application of this and fix the disk space problem.\n\nAlso to be really useful it should probably find a way to automatically fetch\nthe debuginfos (I cheated and just installed them in advance). If nobody else\ndoes it I can probably do the rewrite myself again at some point.\n\nMy hope at some point was that desktops would support it in their builtin\ncrash reporters, but at least the KDE people I talked too seemed to be happy\nwith their user space only solution.\n\nAlan sayeth:\n\n I don\u0027t believe that piping as such as neccessarily the right model, but\n the ability to intercept and processes core dumps from user space is asked\n for by many enterprise users as well. They want to know about, capture,\n analyse and process core dumps, often centrally and in automated form.\n\n[akpm@osdl.org: loff_t !\u003d unsigned long]\nSigned-off-by: Andi Kleen \u003cak@suse.de\u003e\nCc: Alan Cox \u003calan@lxorguk.ukuu.org.uk\u003e\nSigned-off-by: Andrew Morton \u003cakpm@osdl.org\u003e\nSigned-off-by: Linus Torvalds \u003ctorvalds@osdl.org\u003e\n" }, { "commit": "29cbc78b90a73ad80f2f58ba2927956cf663abed", "tree": "e72fdb9c1c055da47b4cd8834bc944af8efc1ed8", "parents": [ "013bf2c50ed943e9c23a2145d3ea7c4d88cda310" ], "author": { "name": "Andi Kleen", "email": "ak@suse.de", "time": "Sat Sep 30 01:47:55 2006 +0200" }, "committer": { "name": "Andi Kleen", "email": "andi@basil.nowhere.org", "time": "Sat Sep 30 01:47:55 2006 +0200" }, "message": "[PATCH] x86: Clean up x86 NMI sysctls\n\nUse prototypes in headers\nDon\u0027t define panic_on_unrecovered_nmi for all architectures\n\nCc: dzickus@redhat.com\n\nSigned-off-by: Andi Kleen \u003cak@suse.de\u003e\n" }, { "commit": "f400e198b2ed26ce55b22a1412ded0896e7516ac", "tree": "a3d78bfc1c20635e199fe0fe85aaa1d8792acc58", "parents": [ "959ed340f4867fda7684340625f60e211c2296d6" ], "author": { "name": "Sukadev Bhattiprolu", "email": "sukadev@us.ibm.com", "time": "Fri Sep 29 02:00:07 2006 -0700" }, "committer": { "name": "Linus Torvalds", "email": "torvalds@g5.osdl.org", "time": "Fri Sep 29 09:18:12 2006 -0700" }, "message": "[PATCH] pidspace: is_init()\n\nThis is an updated version of Eric Biederman\u0027s is_init() patch.\n(http://lkml.org/lkml/2006/2/6/280).

Zone reclaim may remove 32 unmapped\npages. File I/O will use these pages for the next read/write requests and the\nunmapped pages increase. After the zone has filled up again zone reclaim will\nremove it again after only 32 pages. This cycle is too inefficient and there\nare potentially too many zone reclaim cycles.\n\nWith the 1% boundary we may still remove all unmapped pages for file I/O in\nzone reclaim pass.
