This makes it no longer safe to set the output\nlock\u0027s fl_type to F_UNLCK before looking for a conflict, since that\nmeans searching for a conflict against a lock with type F_UNLCK.\n\nThis fixes a regression which causes F_GETLK to incorrectly report no\nconflict on most filesystems (including any filesystem that doesn\u0027t do\nits own locking).\n\nAlso fix posix_lock_to_flock() to copy the lock type. This isn\u0027t\nstrictly necessary, since the caller already does this; but it seems\nless likely to cause confusion in the future.\n\nThanks to Doug Chapman for the bug report.\n\nSigned-off-by: \"J.

We can\u0027t do anything for filesystems that have actual\n \u003e32-bit inode numbers, but on filesystems that generate i_ino values on the\n fly, we should try to have them fit in 32 bits. We could trivially fix this\n by making the static counters in new_inode and iunique 32 bits, but...\n\n- many filesystems call new_inode and assume that the i_ino values they are\n given are unique. They are not guaranteed to be so, since the static\n counter can wrap. This problem is exacerbated by the fix for #1.\n\n- after allocating a new inode, some filesystems call iunique to try to get\n a unique i_ino value, but they don\u0027t actually add their inodes to the\n hashtable, and so they\u0027re still not guaranteed to be unique if that counter\n wraps.\n\nThis patch set takes the simpler approach of simply using iunique and hashing\nthe inodes afterward. Christoph H. previously mentioned that he thought that\nthis approach may slow down lookups for filesystems that currently hash their\ninodes.\n\nThe questions are:\n\n1) how much would this slow down lookups for these filesystems?\n2) is it enough to justify adding more infrastructure to avoid it?\n\nWhat might be best is to start with this approach and then only move to using\nIDR or some other scheme if these extra inodes in the hashtable prove to be\nproblematic.\n\nI\u0027ve done some cursory testing with this patch and the overhead of hashing and\nunhashing the inodes with pipefs is pretty low -- just a few seconds of system\ntime added on to the creation and destruction of 10 million pipes (very\nsimilar to the overhead that the IDR approach would add).\n\nThe hard thing to measure is what effect this has on other filesystems. I\u0027m\nopen to ways to try and gauge this.\n\nAgain, I\u0027ve only converted pipefs as an example. If this approach is\nacceptable then I\u0027ll start work on patches to convert other filesystems.\n\nWith a pretty-much-worst-case microbenchmark provided by Eric Dumazet\n\u003cdada1@cosmosbay.com\u003e:\n\nhashing patch (pipebench):\nsys 1m15.329s\nsys 1m16.249s\nsys 1m17.169s\n\nunpatched (pipebench):\nsys 1m9.836s\nsys 1m12.541s\nsys 1m14.153s\n\nWhich works out to 1.05642174294555027017. So ~5-6% slowdown.\n\nThis patch:\n\nWhen a 32-bit program that was not compiled with large file offsets does a\nstat and gets a st_ino value back that won\u0027t fit in the 32 bit field, glibc\n(correctly) generates an EOVERFLOW error. We can\u0027t do anything about fs\u0027s\nwith larger permanent inode numbers, but when we generate them on the fly, we\nought to try and have them fit within a 32 bit field.\n\nThis patch takes the first step toward this by making the static counters in\nthese two functions be 32 bits.\n\n[jlayton@redhat.com: mention that it\u0027s only the case for 32bit, non-LFS stat]\nSigned-off-by: Jeff Layton \u003cjlayton@redhat.com\u003e\nCc: Christoph Hellwig \u003chch@lst.de\u003e\nCc: Al Viro \u003cviro@zeniv.linux.org.uk\u003e\nSigned-off-by: Andrew Morton \u003cakpm@linux-foundation.org\u003e\nSigned-off-by: Linus Torvalds \u003ctorvalds@linux-foundation.org\u003e\n" }, { "commit": "b140f25108a8b11aa4903014814988549838b324", "tree": "466b0c1a8056a2307c8219d1dfc5c059c043f07d", "parents": [ "ce0be1273d1473a5a7b57bf0b4995b40c22d6b54" ], "author": { "name": "Alexey Kuznetsov", "email": "alexey@openvz.org", "time": "Tue May 08 00:31:57 2007 -0700" }, "committer": { "name": "Linus Torvalds", "email": "torvalds@woody.linux-foundation.org", "time": "Tue May 08 11:15:15 2007 -0700" }, "message": "Invalid return value of execve() resulting in oopses\n\nWhen elf loader fails to map executable (due to memory shortage or because\nbinary is malformed), it can return 0.

From the user\u0027s view there are lots of different filesystem\ntypes. The user is not even much concerned if the filesystem is fuse based\nor not. So there\u0027s a conflict of interest in how this should be\nrepresented in fstab, mtab and /proc/mounts.\n\nThe current scheme is to encode the real filesystem type in the mount\nsource. So an sshfs mount looks like this:\n\n sshfs#user@server:/ /mnt/server fuse rw,nosuid,nodev,...\n\nThis url-ish syntax works OK for sshfs and similar filesystems. However\nfor block device based filesystems (ntfs-3g, zfs) it doesn\u0027t work, since\nthe kernel expects the mount source to be a real device name.\n\nA possibly better scheme would be to encode the real type in the type\nfield as \"type.subtype\".

Looking at the code again, I\nnoticed that we already hold the epoll semaphore in read, and this\n(together with other locking conditions that hold while doing an\nepoll_wait()) can lead to a smarter way [1] to \"ship\" events to userspace\n(in a single pass).\n\nThis is a stress application that can be used to test the new code. It\nspwans multiple thread and call epoll_wait() and epoll_ctl() from many\nthreads. Stress tested on my dual Opteron 254 w/out any problems.\n\nhttp://www.xmailserver.org/totalmess.c\n\nThis is not a benchmark, just something that tries to stress and exploit\npossible problems with the new code.\nAlso, I made a stupid micro-benchmark:\n\nhttp://www.xmailserver.org/epwbench.c\n\n[1] Considering that epoll must be thread-safe, there are five ways we can\n be hit during an epoll_wait() transfer loop (ep_send_events()):\n\n 1) The epoll fd going away and calling ep_free\n This just can\u0027t happen, since we did an fget() in sys_epoll_wait\n\n 2) An epoll_ctl(EPOLL_CTL_DEL)\n This can\u0027t happen because epoll_ctl() gets ep-\u003esem in write, and\n we\u0027re holding it in read during ep_send_events()\n\n 3) An fd stored inside the epoll fd going away\n This can\u0027t happen because in eventpoll_release_file() we get\n ep-\u003esem in write, and we\u0027re holding it in read during\n ep_send_events()\n\n 4) Another epoll_wait() happening on another thread\n They both can be inside ep_send_events() at the same time, we get\n (splice) the ready-list under the spinlock, so each one will get\n its own ready list. Note that an fd cannot be at the same time\n inside more than one ready list, because ep_poll_callback() will\n not re-queue it if it sees it already linked:\n\n if (ep_is_linked(\u0026epi-\u003erdllink))\n goto is_linked;\n\n Another case that can happen, is two concurrent epoll_wait(),\n coming in with a userspace event buffer of size, say, ten.\n Suppose there are 50 event ready in the list. The first\n epoll_wait() will \"steal\" the whole list, while the second, seeing\n no events, will go to sleep. But at the end of ep_send_events() in\n the first epoll_wait(), we will re-inject surplus ready fds, and we\n will trigger the proper wake_up to the second epoll_wait().\n\n 5) ep_poll_callback() hitting us asyncronously\n This is the tricky part. As I said above, the ep_is_linked() test\n done inside ep_poll_callback(), will guarantee us that until the\n item will result linked to a list, ep_poll_callback() will not try\n to re-queue it again (read, write data on any of its members). When\n we do a list_del() in ep_send_events(), the item will still satisfy\n the ep_is_linked() test (whatever data is written in prev/next,\n it\u0027ll never be its own pointer), so ep_poll_callback() will still\n leave us alone. It\u0027s only after the eventual smp_mb()+INIT_LIST_HEAD(\u0026epi-\u003erdllink)\n that it\u0027ll become visible to ep_poll_callback(), but at the point\n we\u0027re already past it.\n\n[akpm@osdl.org: 80 cols]\nSigned-off-by: Davide Libenzi \u003cdavidel@xmailserver.org\u003e\nSigned-off-by: Andrew Morton \u003cakpm@linux-foundation.org\u003e\nSigned-off-by: Linus Torvalds \u003ctorvalds@linux-foundation.org\u003e\n" }, { "commit": "fedee54d8f12cdfde299f181fec5c62b0c647ad6", "tree": "815a5de82d0c242bb1e6a012a237d0715c3b08af", "parents": [ "753e9c5cd9b123156152c66c816f751954b15e53" ], "author": { "name": "Dmitriy Monakhov", "email": "dmonakhov@sw.ru", "time": "Tue May 08 00:25:34 2007 -0700" }, "committer": { "name": "Linus Torvalds", "email": "torvalds@woody.linux-foundation.org", "time": "Tue May 08 11:15:01 2007 -0700" }, "message": "ext3: dirindex error pointer issues\n\n- ext3_dx_find_entry() exit with out setting proper error pointer\n\n- do_split() exit with out setting proper error pointer\n it is realy painful because many callers contain folowing code:\n\n de \u003d do_split(handle,dir, \u0026bh, frame, \u0026hinfo, \u0026retval);\n if (!(de))\n return retval;\n \u003c\u003c\u003c WOW retval wasn\u0027t changed by do_split(), so caller failed\n \u003c\u003c\u003c but return SUCCESS :)\n\n- Rearrange do_split() error path.
