      "message": "[PATCH] proc: readdir race fix (take 3)\n\nThe problem: An opendir, readdir, closedir sequence can fail to report\nprocess ids that are continually in use throughout the sequence of system\ncalls.  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.

      "message": "[PATCH] pidhash: Refactor the pid hash table\n\nSimplifies the code, reduces the need for 4 pid hash tables, and makes the\ncode more capable.\n\nIn the discussions I had with Oleg it was felt that to a large extent the\ncleanup itself justified the work.  With struct pid being dynamically\nallocated meant we could create the hash table entry when the pid was\nallocated and free the hash table entry when the pid was freed.  Instead of\nplaying with the hash lists when ever a process would attach or detach to a\nprocess.\n\nFor myself the fact that it gave what my previous task_ref patch gave for free\nwith simpler code was a big win.  The problem is that if you hold a reference\nto struct task_struct you lock in 10K of low memory.  If you do that in a user\ncontrollable way like /proc does, with an unprivileged but hostile user space\napplication with typical resource limits of 1000 fds and 100 processes I can\ntrigger the OOM killer by consuming all of low memory with task structs, on a\nmachine wight 1GB of low memory.\n\nIf I instead hold a reference to struct pid which holds a pointer to my\ntask_struct, I don\u0027t suffer from that problem because struct pid is 2 orders\nof magnitude smaller.  In fact struct pid is small enough that most other\nkernel data structures dwarf it, so simply limiting the number of referring\ndata structures is enough to prevent exhaustion of low memory.\n\nThis splits the current struct pid into two structures, struct pid and struct\npid_link, and reduces our number of hash tables from PIDTYPE_MAX to just one.\nstruct pid_link is the per process linkage into the hash tables and lives in\nstruct task_struct.  struct pid is given an indepedent lifetime, and holds\npointers to each of the pid types.\n\nThe independent life of struct pid simplifies attach_pid, and detach_pid,\nbecause we are always manipulating the list of pids and not the hash table.\nIn addition in giving struct pid an indpendent life it makes the concept much\nmore powerful.\n\nKernel data structures can now embed a struct pid * instead of a pid_t and\nnot suffer from pid wrap around problems or from keeping unnecessarily\nlarge amounts of memory allocated.\n\nSigned-off-by: Eric W.

Contrary,\nboot_cpu\u0027s idle thread explicitely registers itself for each pid_type with nr\n\u003d 0.\n\ncopy_process() already checks p-\u003epid !\u003d 0 before process_counts++, I think we\ncan just skip attach_pid() calls and job control inits for idle threads and\nkill unhash_process().  We don\u0027t need to cleanup -\u003eproc_dentry in fork_idle()\nbecause with this patch idle threads are never hashed in\nkernel/pid.c:pid_hash[].\n\nWe don\u0027t need to hash pid \u003d\u003d 0 in pidmap_init().  free_pidmap() is never\ncalled with pid \u003d\u003d 0 arg, so it will never be reused.  So it is still possible\nto use pid \u003d\u003d 0 in any PIDTYPE_xxx namespace from kernel/pid.c\u0027s POV.\n\nHowever with this patch we don\u0027t hash pid \u003d\u003d 0 for PIDTYPE_PID case.  We still\nhave have PIDTYPE_PGID/PIDTYPE_SID entries with pid \u003d\u003d 0: /sbin/init and\nkernel threads which don\u0027t call daemonize().\n\nSigned-off-by: Oleg Nesterov \u003coleg@tv-sign.ru\u003e\nCc: \"Eric W.

      "message": "[PATCH] pidhash: kill switch_exec_pids\n\nswitch_exec_pids is only called from de_thread by way of exec, and it is\nonly called when we are exec\u0027ing from a non thread group leader.\n\nCurrently switch_exec_pids gives the leader the pid of the thread and\nunhashes and rehashes all of the process groups.  The leader is already in\nthe EXIT_DEAD state so no one cares about it\u0027s pids.  The only concern for\nthe leader is that __unhash_process called from release_task will function\ncorrectly.  If we don\u0027t touch the leader at all we know that\n__unhash_process will work fine so there is no need to touch the leader.\n\nFor the task becomming the thread group leader, we just need to give it the\npid of the old thread group leader, add it to the task list, and attach it\nto the session and the process group of the thread group.\n\nCurrently de_thread is also adding the task to the task list which is just\nsilly.\n\nCurrently the only leader of __detach_pid besides detach_pid is\nswitch_exec_pids because of the ugly extra work that was being\nperformed.\n\nSo this patch removes switch_exec_pids because it is doing too much, it is\ncreating an unnecessary special case in pid.c, duing work duplicated in\nde_thread, and generally obscuring what it is going on.\n\nThe necessary work is added to de_thread, and it seems to be a little\nclearer there what is going on.\n\nSigned-off-by: Eric W.
