The ELF core dump code has one use of off_t when writing out segments. Some of the segments may be passed the 2GB limit of an off_t, even on a 32-bit system, so it's important to use loff_t instead. This fixes a corrupted core dump in the bigcore test in GDB's testsuite.

We should never apply a lookup intent to anything other than the last path component in an open(), create() or access() call. Introduce the helper nfs_lookup_check_intent() which always returns zero if LOOKUP_CONTINUE or LOOKUP_PARENT are set, and returns the intent flags if we're on the last component of the lookup. By doing so, we fix a bug in open(O_EXCL), where we may end up optimizing away a real lookup of the parent directory.

Getting rid of sloppy logics: a) in do_follow_link() we have the wrong vfsmount dropped if our symlink had been mounted on something. Currently it worls only because we never get such situation (modulo filesystem playing dirty tricks on us). And it obfuscates already convoluted logics... b) same goes for open_namei(). c) in __link_path_walk() we have another "it should never happen" sloppiness - out_dput: there does double-free on underlying vfsmount and leaks the covering one if we hit it just after crossing a mountpoint. Again, wrong vfsmount getting dropped. d) another too-early-mntput() race - in do_follow_mount() we need to postpone conditional mntput(path->mnt) until after dput(path->dentry). Again, this one happens only in it-currently-never-happens-unless-some-fs-plays-dirty scenario...

In open_namei() exit_dput: we have mntput() done in the wrong order - if nd->mnt != path.mnt we end up doing mntput(nd->mnt); nd->mnt = path.mnt; dput(nd->dentry); mntput(nd->mnt); which drops nd->dentry too late.

In open_namei(), __follow_down() loop turned into __follow_mount(). Instead of if we are on a mountpoint dentry if O_NOFOLLOW checks fail drop path.dentry drop nd return do equivalent of follow_mount(&path.mnt, &path.dentry) nd->mnt = path.mnt we do if __follow_mount(path) had, indeed, traversed mountpoint /* now both nd->mnt and path.mnt are pinned down */ if O_NOFOLLOW checks fail drop path.dentry drop path.mnt drop nd return mntput(nd->mnt) nd->mnt = path.mnt Now __follow_down() can be folded into follow_down() - no other callers left. We need to reorder dput()/mntput() there - same problem as in follow_mount(). Equivalent transformation + fix for a bug in O_NOFOLLOW handling - we used to get -ELOOP if we had the same fs mounted on /foo and /bar, had something bound on /bar/baz and tried to open /foo/baz with O_NOFOLLOW.

New helper: __follow_mount(struct path *path). Same as follow_mount(), except that we do *not* do mntput() after the first lookup_mnt(). IOW, original path->mnt stays pinned down. We also take care to do dput() before mntput() in the loop body (follow_mount() also needs that reordering, but that will be done later in the series). The following are equivalent, assuming that path.mnt == x: (1) follow_mount(&path.mnt, &path.dentry) (2) __follow_mount(&path); if (path->mnt != x) mntput(x); (3) if (__follow_mount(&path)) mntput(x); Callers of follow_mount() in __link_path_walk() converted to (2).

In open_namei() we never use path.mnt or path.dentry after exit: or ok:. Assignment of path.dentry in case of LAST_BIND is dead code and only obfuscates already convoluted function; assignment of path.mnt after __do_follow_link() can be moved down to the place where we set path.dentry.

mntget(path->mnt) in do_follow_link() moved down to right before the __do_follow_link() call and rigth after loop: resp. dput()+mntput() on non-ELOOP branch moved up to right after __do_follow_link() call. resulting loop: mntget(path->mnt); path_release(nd); dput(path->mnt); mntput(path->mnt); replaced with equivalent dput(path->mnt); path_release(nd); Equivalent transformations - the reason why we have that mntget() is that __do_follow_link() can drop a reference to nd->mnt and that's what holds path->mnt. So that call can happen at any point prior to __do_follow_link() touching nd->mnt. The rest is obvious. NOTE: current tree relies on symlinks *never* being mounted on anything. It's not hard to get rid of that assumption (actually, that will come for free later in the series). For now we are just not making the situation worse than it is.

fix for too early mntput() in open_namei() - we pin path.mnt down for the duration of __do_follow_link(). Otherwise we could get the fs where our symlink lived unmounted while we were in __do_follow_link(). That would end up with dentry of symlink staying pinned down through the fs shutdown.

We set path.mnt to nd->mnt after path_lookup() and __do_follow_link(). In __follow_down() loop we use &path.mnt instead of &nd->mnt and set nd->mnt to path.mnt immediately after that loop.

OK, here comes a patch series that hopefully should close all too-early-mntput() races in fs/namei.c. Entire area is convoluted as hell, so I'm splitting that series into _very_ small chunks. Patches alread in the tree close only (very wide) races in following symlinks (see "busy inodes after umount" thread some time ago). Unfortunately, quite a few narrower races of the same nature were not closed. Hopefully this should take care of all of them.

When fsync() runs wait_on_page_writeback_range() it only inspects pages which are actually under I/O (PAGECACHE_TAG_WRITEBACK). If a page completed I/O prior to wait_on_page_writeback_range() looking at it, it is supposed to have recorded its I/O error state in the address_space. But mpage_mpage_end_io_write() forgot to set the address_space error flag in this case.

Fix a bug in list scanning that can cause us to skip the last buffer on the checkpoint list (and hence fail to do any progress under some rather unfavorable conditions). The problem is we first do jh=next_jh and then test } while (jh!=last_jh); Hence we skip the last buffer on the list (if it was not the only buffer on the list). As we already do jh=next_jh; in the beginning of the loop we are safe to just remove the assignment in the end. It can happen that 'jh' will be freed at the point we test jh != last_jh but that does not matter as we never *dereference* the pointer.

This cleans up the /proc/device-tree representation of the Open Firmware device-tree on ppc and ppc64. It does the following things: - Workaround an issue in some Apple device-trees where a property may exist with the same name as a child node of the parent. We now simply "drop" the property instead of creating duplicate entries in /proc with random result... - Do not try to chop off the "@0" at the end of a node name whose unit address is 0. This is not useful, inconsistent, and the code was buggy and didn't always work anyway. - Do not create symlinks for the short name and unit address parts of a node. These were never really used, bloated the memory footprint of the device-tree with useless struct proc_dir_entry and their matching dentry and inode cache bloat. This results in smaller code, smaller memory footprint, and a more accurate view of the tree presented to userland.
