After all of the\nusers have been update it is my intention to remove the variants that take a\npid_t as using pid_t can be more work (an extra hash table lookup) and\ndifficult to get right in the presence of multiple pid namespaces.\n\nThere are two kinds of functions introduced in this patch. The are the\ngeneral use functions kill_pgrp and kill_pid which take a priv argument that\nis ultimately used to create the appropriate siginfo information, Then there\nare _kill_pgrp_info, kill_pgrp_info, kill_pid_info the internal implementation\nhelpers that take an explicit siginfo.\n\nThe distinction is made because filling out an explcit siginfo is tricky, and\nwill be even more tricky when pid namespaces are introduced.\n\nSigned-off-by: Eric W.

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.

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.
