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 chroot check was\nasking a question about the visibility of files to the calling process and\nit was actually checking the destination process, and not the files\nthemselves. That test was clearly bogus.\n\nIn my first pass through I simply fixed the test to check the visibility of\nthe files themselves. That naive approach to fixing the permissions was\ntoo strict and resulted in cases where a task could not even see all of\nit\u0027s file descriptors.\n\nWhat has disturbed me about relaxing this check is that file descriptors\nare per-process private things, and they are occasionaly used a user space\ncapability tokens. Looking a little farther into the symlink path on /proc\nI did find userid checks and a check for capability (CAP_DAC_OVERRIDE) so\nthere were permissions checking this.\n\nBut I was still concerned about privacy. Besides /proc there is only one\nother way to find out this kind of information, and that is ptrace. ptrace\nhas been around for a long time and it has a well established security\nmodel.\n\nSo after thinking about it I finally realized that the permission checks\nthat make sense are the permission checks applied to ptrace_attach. The\nchecks are simple per process, and won\u0027t cause nasty surprises for people\ncoming from less capable unices.\n\nUnfortunately there is one case that the current ptrace_attach test does\nnot cover: Zombies and kernel threads. Single stepping those kinds of\nprocesses is impossible. Being able to see which file descriptors are open\non these tasks is important to lsof, fuser and friends. So for these\nspecial processes I made the rule you can\u0027t find out unless you have\nCAP_SYS_PTRACE.\n\nThese proc permission checks should now conform to the principle of least\nsurprise.

Unfortunately it does not prevent us from returning a stale dcache\nentry. This race has been explicitly plugged in proc_pid_lookup but there is\nnothing to confine it to just that proc lookup function.\n\nSo to prevent the race I call revalidate explictily in all of the proc lookup\nfunctions after I call d_add, and report an error if the revalidate does not\nsucceed.\n\nYears ago Al Viro did something similar but those changes got lost in the\nchurn.\n\nSigned-off-by: Eric W.

There was a\nsmall patch in there that I find to be very useful since it allows the\ndisplay of the locality of the pages in use by a process. I reworked that\npatch and came up with a /proc/\u003cpid\u003e/numa_maps that gives more information\nabout the vma\u0027s of a process. numa_maps is indexes by the start address\nfound in /proc/\u003cpid\u003e/maps. F.e. with this patch you can see the page use\nof the \"getty\" process:\n\nmargin:/proc/12008 # cat maps\n00000000-00004000 r--p 00000000 00:00 0\n2000000000000000-200000000002c000 r-xp 00000000 08:04 516 /lib/ld-2.3.3.so\n2000000000038000-2000000000040000 rw-p 00028000 08:04 516 /lib/ld-2.3.3.so\n2000000000040000-2000000000044000 rw-p 2000000000040000 00:00 0\n2000000000058000-2000000000260000 r-xp 00000000 08:04 54707842 /lib/tls/libc.so.6.1\n2000000000260000-2000000000268000 ---p 00208000 08:04 54707842 /lib/tls/libc.so.6.1\n2000000000268000-2000000000274000 rw-p 00200000 08:04 54707842 /lib/tls/libc.so.6.1\n2000000000274000-2000000000280000 rw-p 2000000000274000 00:00 0\n2000000000280000-20000000002b4000 r--p 00000000 08:04 9126923 /usr/lib/locale/en_US.utf8/LC_CTYPE\n2000000000300000-2000000000308000 r--s 00000000 08:04 60071467 /usr/lib/gconv/gconv-modules.cache\n2000000000318000-2000000000328000 rw-p 2000000000318000 00:00 0\n4000000000000000-4000000000008000 r-xp 00000000 08:04 29576399 /sbin/mingetty\n6000000000004000-6000000000008000 rw-p 00004000 08:04 29576399 /sbin/mingetty\n6000000000008000-600000000002c000 rw-p 6000000000008000 00:00 0 [heap]\n60000fff7fffc000-60000fff80000000 rw-p 60000fff7fffc000 00:00 0\n60000ffffff44000-60000ffffff98000 rw-p 60000ffffff44000 00:00 0 [stack]\na000000000000000-a000000000020000 ---p 00000000 00:00 0 [vdso]\n\ncat numa_maps\n2000000000000000 default MaxRef\u003d43 Pages\u003d11 Mapped\u003d11 N0\u003d4 N1\u003d3 N2\u003d2 N3\u003d2\n2000000000038000 default MaxRef\u003d1 Pages\u003d2 Mapped\u003d2 Anon\u003d2 N0\u003d2\n2000000000040000 default MaxRef\u003d1 Pages\u003d1 Mapped\u003d1 Anon\u003d1 N0\u003d1\n2000000000058000 default MaxRef\u003d43 Pages\u003d61 Mapped\u003d61 N0\u003d14 N1\u003d15 N2\u003d16 N3\u003d16\n2000000000268000 default MaxRef\u003d1 Pages\u003d2 Mapped\u003d2 Anon\u003d2 N0\u003d2\n2000000000274000 default MaxRef\u003d1 Pages\u003d3 Mapped\u003d3 Anon\u003d3 N0\u003d3\n2000000000280000 default MaxRef\u003d8 Pages\u003d3 Mapped\u003d3 N0\u003d3\n2000000000300000 default MaxRef\u003d8 Pages\u003d2 Mapped\u003d2 N0\u003d2\n2000000000318000 default MaxRef\u003d1 Pages\u003d1 Mapped\u003d1 Anon\u003d1 N2\u003d1\n4000000000000000 default MaxRef\u003d6 Pages\u003d2 Mapped\u003d2 N1\u003d2\n6000000000004000 default MaxRef\u003d1 Pages\u003d1 Mapped\u003d1 Anon\u003d1 N0\u003d1\n6000000000008000 default MaxRef\u003d1 Pages\u003d1 Mapped\u003d1 Anon\u003d1 N0\u003d1\n60000fff7fffc000 default MaxRef\u003d1 Pages\u003d1 Mapped\u003d1 Anon\u003d1 N0\u003d1\n60000ffffff44000 default MaxRef\u003d1 Pages\u003d1 Mapped\u003d1 Anon\u003d1 N0\u003d1\n\ngetty uses ld.so.
