2008-07-26[PATCH] fix RLIM_NOFILE handlingAl Viro3-21/+15
* dup2() should return -EBADF on exceeded sysctl_nr_open * dup() should *not* return -EINVAL even if you have rlimit set to 0; it should get -EMFILE instead. Check for orig_start exceeding rlimit taken to sys_fcntl(). Failing expand_files() in dup{2,3}() now gets -EMFILE remapped to -EBADF. Consequently, remaining checks for rlimit are taken to expand_files(). Signed-off-by: Al Viro <viro@zeniv.linux.org.uk>
2008-07-26[PATCH] get rid of corner case in dup3() entirelyAl Viro1-9/+11
Since Ulrich is OK with getting rid of dup3(fd, fd, flags) completely, to hell the damn thing goes. Corner case for dup2() is handled in sys_dup2() (complete with -EBADF if dup2(fd, fd) is called with fd that is not open), the rest is done in dup3(). Signed-off-by: Al Viro <viro@zeniv.linux.org.uk>

2008-07-26[PATCH] dup3 fixUlrich Drepper1-1/+6
Al Viro notice one cornercase that the new dup3() code. The dup2() function, as a special case, handles dup-ing to the same file descriptor. In this case the current dup3() code does nothing at all. I.e., it ingnores the flags parameter. This shouldn't happen, the close-on-exec flag should be set if requested. In case the O_CLOEXEC bit in the flags parameter is not set the dup3() function should behave in this respect identical to dup2(). This means dup3(fd, fd, 0) should not actively reset the c-o-e flag. The patch below implements this minor change.

2008-07-26[patch 4/4] vfs: immutable inode checking cleanupMiklos Szeredi3-26/+7
Move the immutable and append-only checks from chmod, chown and utimes into notify_change(). Checks for immutable and append-only files are always performed by the VFS and not by the filesystem (see permission() and may_...() in namei.c), so these belong in notify_change(), and not in inode_change_ok(). This should be completely equivalent.

2008-07-26[patch 3/4] fat: dont call notify_changeMiklos Szeredi1-1/+14
The FAT_IOCTL_SET_ATTRIBUTES ioctl() calls notify_change() to change the file mode before changing the inode attributes. Replace with explicit calls to security_inode_setattr(), fat_setattr() and fsnotify_change(). This is equivalent to the original. The reason it is needed, is that later in the series we move the immutable check into notify_change(). That would break the FAT_IOCTL_SET_ATTRIBUTES ioctl, as it needs to perform the mode change regardless of the immutability of the file. [Fix error if fat is built as a module.

2008-07-26[patch 1/4] vfs: utimes: move owner check into inode_change_ok()Miklos Szeredi2-14/+5
Add a new ia_valid flag: ATTR_TIMES_SET, to handle the UTIMES_OMIT/UTIMES_NOW and UTIMES_NOW/UTIMES_OMIT cases. In these cases neither ATTR_MTIME_SET nor ATTR_ATIME_SET is in the flags, yet the POSIX draft specifies that permission checking is performed the same way as if one or both of the times was explicitly set to a timestamp. See the path "vfs: utimensat(): fix error checking for {UTIME_NOW,UTIME_OMIT} case" by Michael Kerrisk for the patch introducing this behavior. This is a cleanup, as well as allowing filesystems (NFS/fuse/...) to perform their own permission checking instead of the default.

2008-07-26[patch 05/14] hpfs: dont call permission()Miklos Szeredi1-1/+1
hpfs_unlink() calls permission() prior to truncating the file. HPFS doesn't define a .permission method, so replace with explicit call to generic_permission(). This is equivalent, except that devcgroup_inode_permission() and security_inode_permission() are not called. The truncation is just an implementation detail of the unlink, so these security checks are unnecessary. I suspect that even calling generic_permission() is unnecessary, since we shouldn't mind if the file isn't writable. But I leave that to the maintainer to decide.

2008-07-26[patch] vfs: fix lookup on deleted directoryMiklos Szeredi1-2/+17
Lookup can install a child dentry for a deleted directory. This keeps the directory dentry alive, and the inode pinned in the cache and on disk, even after all external references have gone away. This isn't a big problem normally, since memory pressure or umount will clear out the directory dentry and its children, releasing the inode. But for UBIFS this causes problems because its orphan area can overflow. Fix this by returning ENOENT for all lookups on a S_DEAD directory before creating a child dentry. Thanks to Zoltan Sogor for noticing this while testing UBIFS, and Artem for the excellent analysis of the problem and testing.

This moves all the ptrace hooks related to exec into tracehook.h inlines. This also lifts the calls for tracing out of the binfmt load_binary hooks into search_binary_handler() after it calls into the binfmt module. This change has no effect, since all the binfmt modules' load_binary functions did the call at the end on success, and now search_binary_handler() does it immediately after return if successful. We consolidate the repeated code, and binfmt modules no longer need to import ptrace_notify().
