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.

For most filesystems, this should be done with simple_set_mnt()\nwhich will set the superblock pointer and then set the root dentry to the\nsuperblock\u0027s s_root (as per the old default behaviour).\n\nThe get_sb() op now returns an integer as there\u0027s now no need to return the\nsuperblock pointer.\n\nThis patch permits a superblock to be implicitly shared amongst several mount\npoints, such as can be done with NFS to avoid potential inode aliasing. In\nsuch a case, simple_set_mnt() would not be called, and instead the mnt_root\nand mnt_sb would be set directly.\n\nThe patch also makes the following changes:\n\n (*) the get_sb_*() convenience functions in the core kernel now take a vfsmount\n pointer argument and return an integer, so most filesystems have to change\n very little.\n\n (*) If one of the convenience function is not used, then get_sb() should\n normally call simple_set_mnt() to instantiate the vfsmount. This will\n always return 0, and so can be tail-called from get_sb().\n\n (*) generic_shutdown_super() now calls shrink_dcache_sb() to clean up the\n dcache upon superblock destruction rather than shrink_dcache_anon().\n\n This is required because the superblock may now have multiple trees that\n aren\u0027t actually bound to s_root, but that still need to be cleaned up. The\n currently called functions assume that the whole tree is rooted at s_root,\n and that anonymous dentries are not the roots of trees which results in\n dentries being left unculled.\n\n However, with the way NFS superblock sharing are currently set to be\n implemented, these assumptions are violated: the root of the filesystem is\n simply a dummy dentry and inode (the real inode for \u0027/\u0027 may well be\n inaccessible), and all the vfsmounts are rooted on anonymous[*] dentries\n with child trees.\n\n [*] Anonymous until discovered from another tree.\n\n (*) The documentation has been adjusted, including the additional bit of\n changing ext2_* into foo_* in the documentation.\n\n[akpm@osdl.org: convert ipath_fs, do other stuff]\nSigned-off-by: David Howells \u003cdhowells@redhat.com\u003e\nAcked-by: Al Viro \u003cviro@zeniv.linux.org.uk\u003e\nCc: Nathan Scott \u003cnathans@sgi.com\u003e\nCc: Roland Dreier \u003crolandd@cisco.com\u003e\nSigned-off-by: Andrew Morton \u003cakpm@osdl.org\u003e\nSigned-off-by: Linus Torvalds \u003ctorvalds@osdl.org\u003e\n" }, { "commit": "e0182909297da8d38a5d473ae7bee3d0324632a1", "tree": "0c5c06bac1d626ba66aba1142f439b0f34c75282", "parents": [ "ac03221a4fdda9bfdabf99bcd129847f20fc1d80" ], "author": { "name": "Al Viro", "email": "viro@zeniv.linux.org.uk", "time": "Thu May 18 08:28:02 2006 -0400" }, "committer": { "name": "Al Viro", "email": "viro@zeniv.linux.org.uk", "time": "Tue Jun 20 05:25:24 2006 -0400" }, "message": "[PATCH] proc_loginuid_write() uses simple_strtoul() on non-terminated array\n\nSigned-off-by: Al Viro \u003cviro@zeniv.linux.org.uk\u003e\n" }, { "commit": "ca99c1da080345e227cfb083c330a184d42e27f3", "tree": "e417b4c456ae31dc1dde8027b6be44a1a9f19395", "parents": [ "fb30d64568fd8f6a21afef987f11852a109723da" ], "author": { "name": "Dipankar Sarma", "email": "dipankar@in.ibm.com", "time": "Tue Apr 18 22:21:46 2006 -0700" }, "committer": { "name": "Linus Torvalds", "email": "torvalds@g5.osdl.org", "time": "Wed Apr 19 09:13:51 2006 -0700" }, "message": "[PATCH] Fix file lookup without ref\n\nThere are places in the kernel where we look up files in fd tables and\naccess the file structure without holding refereces to the file.

Originally it was called whenever rss or\ntotal_vm got raised. Then many of those callsites were replaced by a timer\ntick call from account_system_time. Now Frank van Maarseveen reports that to\nbe found inadequate. How about this? Works for Frank.\n\nReplace update_mem_hiwater, a poor combination of two unrelated ops, by macros\nupdate_hiwater_rss and update_hiwater_vm. Don\u0027t attempt to keep\nmm-\u003ehiwater_rss up to date at timer tick, nor every time we raise rss (usually\nby 1): those are hot paths. Do the opposite, update only when about to lower\nrss (usually by many), or just before final accounting in do_exit. Handle\nmm-\u003ehiwater_vm in the same way, though it\u0027s much less of an issue. Demand\nthat whoever collects these hiwater statistics do the work of taking the\nmaximum with rss or total_vm.\n\nAnd there has been no collector of these hiwater statistics in the tree. The\nnew convention needs an example, so match Frank\u0027s usage by adding a VmPeak\nline above VmSize to /proc/\u003cpid\u003e/status, and also a VmHWM line above VmRSS\n(High-Water-Mark or High-Water-Memory).\n\nThere was a particular anomaly during mremap move, that hiwater_vm might be\ncaptured too high. A fleeting such anomaly remains, but it\u0027s quickly\ncorrected now, whereas before it would stick.\n\nWhat locking? None: if the app is racy then these statistics will be racy,\nit\u0027s not worth any overhead to make them exact. But whenever it suits,\nhiwater_vm is updated under exclusive mmap_sem, and hiwater_rss under\npage_table_lock (for now) or with preemption disabled (later on): without\ngoing to any trouble, minimize the time between reading current values and\nupdating, to minimize those occasions when a racing thread bumps a count up\nand back down in between.\n\nSigned-off-by: Hugh Dickins \u003chugh@veritas.com\u003e\nSigned-off-by: Andrew Morton \u003cakpm@osdl.org\u003e\nSigned-off-by: Linus Torvalds \u003ctorvalds@osdl.org\u003e\n" }, { "commit": "4294621f41a85497019fae64341aa5351a1921b7", "tree": "fdeb7eb44384a99d0679ffa6de5019bab0ea2166", "parents": [ "404351e67a9facb475abf1492245374a28d13e90" ], "author": { "name": "Hugh Dickins", "email": "hugh@veritas.com", "time": "Sat Oct 29 18:16:05 2005 -0700" }, "committer": { "name": "Linus Torvalds", "email": "torvalds@g5.osdl.org", "time": "Sat Oct 29 21:40:38 2005 -0700" }, "message": "[PATCH] mm: rss \u003d file_rss + anon_rss\n\nI was lazy when we added anon_rss, and chose to change as few places as\npossible.

And update anon_rss\nupfront, typically in memory.c, not tucked away in page_add_anon_rmap.\n\nSigned-off-by: Hugh Dickins \u003chugh@veritas.com\u003e\nSigned-off-by: Andrew Morton \u003cakpm@osdl.org\u003e\nSigned-off-by: Linus Torvalds \u003ctorvalds@osdl.org\u003e\n" }, { "commit": "dfcd3c0dc426bb75770c34b40e14f2da8845ea62", "tree": "bd7e9f8463a18025c4775c6cdf22abbbd4236b64", "parents": [ "e46a5e28c201f703c18b47b108bfddec44f897c4" ], "author": { "name": "Andi Kleen", "email": "ak@suse.de", "time": "Sat Oct 29 18:15:48 2005 -0700" }, "committer": { "name": "Linus Torvalds", "email": "torvalds@g5.osdl.org", "time": "Sat Oct 29 21:40:35 2005 -0700" }, "message": "[PATCH] Convert mempolicies to nodemask_t\n\nThe NUMA policy code predated nodemask_t so it used open coded bitmaps.\nConvert everything to nodemask_t.
