For this race to trigger the process that proc_pid_readdir stops at\nmust exit before readdir is called again.\n\nThis can cause ps to fail to report processes, and it is in violation of\nposix guarantees and normal application expectations with respect to\nreaddir.\n\nCurrently there is no way to work around this problem in user space short\nof providing a gargantuan buffer to user space so the directory read all\nhappens in on system call.\n\nThis patch implements the normal directory semantics for proc, that\nguarantee that a directory entry that is neither created nor destroyed\nwhile reading the directory entry will be returned. For directory that are\neither created or destroyed during the readdir you may or may not see them.\n Furthermore you may seek to a directory offset you have previously seen.\n\nThese are the guarantee that ext[23] provides and that posix requires, and\nmore importantly that user space expects. Plus it is a simple semantic to\nimplement reliable service. It is just a matter of calling readdir a\nsecond time if you are wondering if something new has show up.\n\nThese better semantics are implemented by scanning through the pids in\nnumerical order and by making the file offset a pid plus a fixed offset.\n\nThe pid scan happens on the pid bitmap, which when you look at it is\nremarkably efficient for a brute force algorithm. Given that a typical\ncache line is 64 bytes and thus covers space for 64*8 \u003d\u003d 200 pids. There\nare only 40 cache lines for the entire 32K pid space. A typical system\nwill have 100 pids or more so this is actually fewer cache lines we have to\nlook at to scan a linked list, and the worst case of having to scan the\nentire pid bitmap is pretty reasonable.\n\nIf we need something more efficient we can go to a more efficient data\nstructure for indexing the pids, but for now what we have should be\nsufficient.\n\nIn addition this takes no additional locks and is actually less code than\nwhat we are doing now.\n\nAlso another very subtle bug in this area has been fixed. It is possible\nto catch a task in the middle of de_thread where a thread is assuming the\nthread of it\u0027s thread group leader. This patch carefully handles that case\nso if we hit it we don\u0027t fail to return the pid, that is undergoing the\nde_thread dance.\n\nThanks to KAMEZAWA Hiroyuki \u003ckamezawa.hiroyu@jp.fujitsu.com\u003e for\nproviding the first fix, pointing this out and working on it.\n\n[oleg@tv-sign.ru: fix it]\nSigned-off-by: Eric W.

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.

Not all embedded devices require\nit, some can make do with just JFFS2, NFS, ramfs, etc - none of which require\nthe block layer to be present.\n\nThis patch does the following:\n\n (*) Introduces CONFIG_BLOCK to disable the block layer, buffering and blockdev\n support.\n\n (*) Adds dependencies on CONFIG_BLOCK to any configuration item that controls\n an item that uses the block layer. This includes:\n\n (*) Block I/O tracing.\n\n (*) Disk partition code.\n\n (*) All filesystems that are block based, eg: Ext3, ReiserFS, ISOFS.\n\n (*) The SCSI layer. As far as I can tell, even SCSI chardevs use the\n \t block layer to do scheduling. Some drivers that use SCSI facilities -\n \t such as USB storage - end up disabled indirectly from this.\n\n (*) Various block-based device drivers, such as IDE and the old CDROM\n \t drivers.\n\n (*) MTD blockdev handling and FTL.\n\n (*) JFFS - which uses set_bdev_super(), something it could avoid doing by\n \t taking a leaf out of JFFS2\u0027s book.\n\n (*) Makes most of the contents of linux/blkdev.h, linux/buffer_head.h and\n linux/elevator.h contingent on CONFIG_BLOCK being set. sector_div() is,\n however, still used in places, and so is still available.\n\n (*) Also made contingent are the contents of linux/mpage.h, linux/genhd.h and\n parts of linux/fs.h.\n\n (*) Makes a number of files in fs/ contingent on CONFIG_BLOCK.\n\n (*) Makes mm/bounce.c (bounce buffering) contingent on CONFIG_BLOCK.\n\n (*) set_page_dirty() doesn\u0027t call __set_page_dirty_buffers() if CONFIG_BLOCK\n is not enabled.\n\n (*) fs/no-block.c is created to hold out-of-line stubs and things that are\n required when CONFIG_BLOCK is not set:\n\n (*) Default blockdev file operations (to give error ENODEV on opening).\n\n (*) Makes some /proc changes:\n\n (*) /proc/devices does not list any blockdevs.\n\n (*) /proc/diskstats and /proc/partitions are contingent on CONFIG_BLOCK.\n\n (*) Makes some compat ioctl handling contingent on CONFIG_BLOCK.\n\n (*) If CONFIG_BLOCK is not defined, makes sys_quotactl() return -ENODEV if\n given command other than Q_SYNC or if a special device is specified.\n\n (*) In init/do_mounts.c, no reference is made to the blockdev routines if\n CONFIG_BLOCK is not defined. This does not prohibit NFS roots or JFFS2.\n\n (*) The bdflush, ioprio_set and ioprio_get syscalls can now be absent (return\n error ENOSYS by way of cond_syscall if so).\n\n (*) The seclvl_bd_claim() and seclvl_bd_release() security calls do nothing if\n CONFIG_BLOCK is not set, since they can\u0027t then happen.\n\nSigned-Off-By: David Howells \u003cdhowells@redhat.com\u003e\nSigned-off-by: Jens

In\nthis context, POSIX is referring to sysconf(OPEN_MAX), which is the value\nof current-\u003esignal-\u003erlim[RLIMIT_NOFILE].rlim_cur in the linux kernel, not\nthe compile-time constant which happens to also be named OPEN_MAX. In the\ncurrent code, an application may poll up to max_fdset file descriptors,\neven if this exceeds RLIMIT_NOFILE. The current code also breaks\napplications which poll more than max_fdset descriptors, which worked circa\n2.4.18 when the check was against NR_OPEN, which is 1024*1024. This patch\nenforces the limit precisely as POSIX defines, even if RLIMIT_NOFILE has\nbeen changed at run time with ulimit -n.\n\nTo elaborate on the rationale for this, there are three cases:\n\n1) RLIMIT_NOFILE is at the default value of 1024\n\nIn this (default) case, the patch changes nothing. Calls with nfds \u003e 1024\nfail with EINVAL both before and after the patch, and calls with nfds \u003c\u003d\n1024 pass the check both before and after the patch, since 1024 is the\ninitial value of max_fdset.\n\n2) RLIMIT_NOFILE has been raised above the default\n\nIn this case, poll() becomes more permissive, allowing polling up to\nRLIMIT_NOFILE file descriptors even if less than 1024 have been opened.\nThe patch won\u0027t introduce new errors here. If an application somehow\ndepends on poll() failing when it polls with duplicate or invalid file\ndescriptors, it\u0027s already broken, since this is already allowed below 1024,\nand will also work above 1024 if enough file descriptors have been open at\nsome point to cause max_fdset to have been increased above nfds.\n\n3) RLIMIT_NOFILE has been lowered below the default\n\nIn this case, the system administrator or the user has gone out of their\nway to protect the system from inefficient (or malicious) applications\nwasting kernel memory. The current code allows polling up to 1024 file\ndescriptors even if RLIMIT_NOFILE is much lower, which is not what the user\nor administrator intended. Well-written applications which only poll\nvalid, unique file descriptors will never notice the difference, because\nthey\u0027ll hit the limit on open() first. If an application gets broken\nbecause of the patch in this case, then it was already poorly/maliciously\ndesigned, and allowing it to work in the past was a violation of POSIX and\na DoS risk on low-resource systems.\n\nWith this patch, poll() will permit exactly what POSIX suggests, no more,\nno less, and for any run-time value set with ulimit -n, not just 256 or\n1024. There are existing apps which which poll a large number of file\ndescriptors, some of which may be invalid, and if those numbers stradle\n1024, they currently fail with or without the patch in -mm, though they\nworked fine under 2.4.18.\n\nSigned-off-by: Chris Snook \u003ccsnook@redhat.com\u003e\nSigned-off-by: Andrew Morton \u003cakpm@osdl.org\u003e\nSigned-off-by: Linus Torvalds \u003ctorvalds@osdl.org\u003e\n" }, { "commit": "e518ddb7ba44a3d852c0e41961365844c76eb2bf", "tree": "82bda48f6dac153015ef02fe6f8ccbbfa15151d0", "parents": [ "c16a02d6f5fcfe05dc6fd40aa80a8e1d055300db" ], "author": { "name": "Andreas Mohr", "email": "andi@rhlx01.fht-esslingen.de", "time": "Fri Sep 29 02:01:22 2006 -0700" }, "committer": { "name": "Linus Torvalds", "email": "torvalds@g5.osdl.org", "time": "Fri Sep 29 09:18:22 2006 -0700" }, "message": "[PATCH] fs/namei.c: replace multiple current-\u003efs by shortcut variable\n\nReplace current-\u003efs by fs helper variable to reduce some indirection\noverhead and (at least at the moment, before the current_thread_info() %gs\nPDA improvement is available) get rid of more costly current references.\nReduces fs/namei.o from 37786 to 37082 Bytes (704 Bytes saved).\n\n[akpm@osdl.org: cleanup]\nSigned-off-by: Andreas Mohr \u003candi@lisas.de\u003e\nSigned-off-by: Andrew Morton \u003cakpm@osdl.org\u003e\nSigned-off-by: Linus Torvalds \u003ctorvalds@osdl.org\u003e\n" }, { "commit": "6ea36ddbd1abfe867f1e874a8312bfd811e5fd2c", "tree": "c70f28e5e644440cfa93dac2effdde9040866e9c", "parents": [ "d826380b305971ff9825ef005ff039d655542bbb" ], "author": { "name": "Alexey Dobriyan", "email": "adobriyan@gmail.com", "time": "Fri Sep 29 02:01:07 2006 -0700" }, "committer": { "name": "Linus Torvalds", "email": "torvalds@g5.osdl.org", "time": "Fri Sep 29 09:18:20 2006 -0700" }, "message": "[PATCH] Ban register_filesystem(NULL);\n\nEveryone passes valid pointer there.\n\nSigned-off-by: Alexey Dobriyan \u003cadobriyan@gmail.com\u003e\nSigned-off-by: Andrew Morton \u003cakpm@osdl.org\u003e\nSigned-off-by: Linus Torvalds \u003ctorvalds@osdl.org\u003e\n" } ], "next": "d826380b305971ff9825ef005ff039d655542bbb" }
