2005-11-07[PATCH] introduce shared mountsRam Pai5-2/+21
This creates shared mounts. A shared mount when bind-mounted to some mountpoint, propagates mount/umount events to each other. All the shared mounts that propagate events to each other belong to the same peer-group.

2005-11-07[PATCH] beginning of the shared-subtree properRam Pai6-6/+62
A private mount does not forward or receive propagation. This patch provides user the ability to convert any mount to private. Signed-off-by: Ram Pai <linuxram@us.ibm.com> Signed-off-by: Al Viro <viro@zeniv.linux.org.uk> Signed-off-by: Linus Torvalds <torvalds@osdl.org>
2005-11-07[PATCH] making namespace_sem globalRam Pai2-24/+23
This removes the per-namespace semaphore in favor of a global semaphore. This can have an effect on namespace scalability.

2005-11-07[PATCH] mount expiry fixesRam Pai1-42/+22
- clean up the ugliness in may_umount_tree() - fix a bug in do_loopback(). after cloning a tree, do_loopback() unlinks only the topmost mount of the cloned tree, leaving behind the children mounts on their corresponding expiry list.

2005-11-07[PATCH] umount_tree() locking changeRam Pai1-33/+51
umount is done under the protection of the namespace semaphore. This can lead to intresting deadlocks when the last reference to a mount is released, if filesystem code is in sufficiently nasty state. This collects all the to-be-released-mounts and releases them after releasing the namespace semaphore. That both reduces the time we are holding namespace semaphore and gets the things more robust.

2005-11-07[PATCH] sanitize the interface of graft_tree().Ram Pai1-6/+6
Old semantics: graft_tree() grabs a reference on the vfsmount before returning success. New one: graft_tree() leaves that to caller. All the callers of graft_tree() immediately dropped that reference anyway. Changing the interface takes care of this unnecessary overhead. Idea proposed by Al Viro.

2005-11-07[PATCH] allow callers of seq_open do allocation themselvesAl Viro1-4/+8

2005-11-07[PATCH] cleanups and bug fix in do_loopback()Al Viro1-19/+22
- check_mnt() on the source of binding should've been unconditional from the very beginning. My fault - as far I could've trace it, that's an old thinko made back in 2001.

2005-11-07[PATCH] saner handling of auto_acct_off() and DQUOT_OFF() in umountAl Viro7-79/+113
The way we currently deal with quota and process accounting that might keep vfsmount busy at umount time is inherently broken; we try to turn them off just in case (not quite correctly, at that) and a) pray umount doesn't fail (otherwise they'll stay turned off) b) pray nobody doesn anything funny just as we turn quota off Moreover, LSM provides hooks for doing the same sort of broken logics. The proper way to deal with that is to introduce the second kind of reference to vfsmount. Semantics: - when the last normal reference is dropped, all special ones are converted to normal ones and if there had been any, cleanup is done. - normal reference can be cloned into a special one - special reference can be converted to normal one; that's a no-op if we'd already passed the point of no return (i.e. mntput() had converted special references to normal and started cleanup). The way it works: e.g. starting process accounting converts the vfsmount reference pinned by the opened file into special one and turns it back to normal when it gets shut down; acct_auto_close() is done when no normal references are left. That way it does *not* obstruct umount(2) and it silently gets turned off when the last normal reference to vfsmount is gone. Which is exactly what we want... The same should be done by LSM module that holds some internal references to vfsmount and wants to shut them down on umount - it should make them special and security_sb_umount_close() will be called exactly when the last normal reference to vfsmount is gone. quota handling is even simpler - we don't use normal file IO anymore, so there's no need to hold vfsmounts at all. DQUOT_OFF() is done from deactivate_super(), where it really belongs. Signed-off-by: Al Viro <viro@zeniv.linux.org.uk> Signed-off-by: Linus Torvalds <torvalds@osdl.org>

2005-11-07[ARM] 3121/1: unconditionally use XCB=101 on ixp2000Lennert Buytenhek1-22/+13
Patch from Lennert Buytenhek Since we have to use XCB=101 instead of XCB=000 on the ixp2400 to prevent it from regularly falling over, and since we have to deal with manual write buffer flushing because of that, we might as well use XCB=101 on all ixp2000 platforms since it's faster than XCB=000.

2005-11-07[ARM] 3118/1: fix and reenable nwfpe extended precision emulation for big-endianLennert Buytenhek4-7/+22
Patch from Lennert Buytenhek nwfpe extended precision emulation used to be broken on big-endian and was therefore disabled. This patch fixes nwfpe so that it copies extended precision floats to/from userspace in the proper word order (similar to patch #2046, see the description of that patch for an explanation) and reenables the Kconfig option.

2005-11-07[ARM] 3117/1: nwfpe kernel memory info leakLennert Buytenhek4-8/+16
Patch from Lennert Buytenhek The routine that nwfpe uses for converting floats/doubles to extended precision fails to zero two bytes of kernel stack. This is not immediately obvious, as the floatx80 structure has 16 bits of implicit padding (by design.) These two bytes are copied to userspace when an stfe is emulated, causing a possible info leak. Make the padding explicit and zero it out in the relevant places. Signed-off-by: Lennert Buytenhek <buytenh@wantstofly.org> Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>

Move some of the m68knommu platform specific irq core support to its own header, irqnode.h.
