Fix f_flags/f_mode in case of lookup_instantiate_filp() from open(pathname, 3)

2009-12-22T17:27:34+00:00

Just set f_flags when shoving struct file into nameidata; don't
postpone that until __dentry_open().  do_filp_open() has correct
value; lookup_instantiate_filp() doesn't - we lose the difference
between O_RDWR and 3 by that point.

We still set .intent.open.flags, so no fs code needs to be changed.

sysfs: Propagate renames to the vfs on demand

2009-12-11T19:24:54+00:00

By teaching sysfs_revalidate to hide a dentry for
a sysfs_dirent if the sysfs_dirent has been renamed,
and by teaching sysfs_lookup to return the original
dentry if the sysfs dirent has been renamed.  I can
show the results of renames correctly without having to
update the dcache during the directory rename.

This massively simplifies the rename logic allowing a lot
of weird sysfs special cases to be removed along with
a lot of now unnecesary helper code.

Cache root in nameidata

2009-06-12T01:35:59+00:00

New field: nd->root.  When pathname resolution wants to know the root,
check if nd->root.mnt is non-NULL; use nd->root if it is, otherwise
copy current->fs->root there.  After path_walk() is finished, we check
if we'd got a cached value in nd->root and drop it.  Before calling
path_walk() we should either set nd->root.mnt to NULL *or* copy (and
pin down) some path to nd->root.  In the latter case we won't be
looking at current->fs->root at all.

vfs: introduce helper function to safely NUL-terminate symlinks

2008-12-31T23:07:38+00:00

A number of filesystems were potentially triggering kernel bugs due to
corrupted symlink names on disk. This function helps safely terminate
the names.

[PATCH vfs-2.6 6/6] vfs: add LOOKUP_RENAME_TARGET intent

2008-10-23T09:13:20+00:00

This adds LOOKUP_RENAME_TARGET intent for lookup of rename destination.

LOOKUP_RENAME_TARGET is going to be used like LOOKUP_CREATE. But since
the destination of rename() can be existing directory entry, so it has a
difference. Although that difference doesn't matter in my usage, this
tells it to user of this intent.

[PATCH] make O_EXCL in nd->intent.flags visible in nd->flags

2008-10-23T09:12:56+00:00

New flag: LOOKUP_EXCL.  Set before doing the final step of pathname
resolution on the paths that have LOOKUP_CREATE and O_EXCL.
