* [XFS] Warn on transaction in flight on read-only remountFelix Blyakher2009-01-27
| | | | | | | | | Till VFS can correctly support read-only remount without racing, use WARN_ON instead of BUG_ON on detecting transaction in flight after quiescing filesystem. Signed-off-by: Felix Blyakher <felixb@sgi.com> Reviewed-by: Christoph Hellwig <hch@lst.de>

* | Long btree pointers are still 64 bit on diskDave Chinner2009-01-21
|/ | | | | | | | | | | | | | | | | | | | | | | | | | | | | [XFS] Long btree pointers are still 64 bit on disk On 32 bit machines with CONFIG_LBD=n, XFS reduces the in memory size of xfs_fsblock_t to 32 bits so that it will fit within 32 bit addressing. However, the disk format for long btree pointers are still 64 bits in size. The recent btree rewrite failed to take this into account when initialising new btree blocks, setting sibling pointers to NULL and checking if they are NULL. Hence checking whether a 64 bit NULL was the same as a 32 bit NULL was failingi resulting in NULL sibling pointers failing to be detected correctly. This showed up as WANT_CORRUPTED_GOTO shutdowns in xfs_btree_delrec. Fix this by making all the comparisons and setting of long pointer btree NULL blocks to the disk format, not the in memory format. i.e. use NULLDFSBNO.

| * xfs: sanity check attr fork sizeChristoph Hellwig2009-01-18
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Recently we have quite a few kerneloops reports about dereferencing a NULL if_data in the attribute fork. From looking over the code this can only happen if we pass a 0 size argument to xfs_iformat_local. This implies some sort of corruption and in fact the only mailinglist report about this from earlier this year was after a powerfail presumably on a system with write cache and without barriers. Add a quick sanity check for the attr fork size in xfs_iformat to catch these early and without an oops. Signed-off-by: Christoph Hellwig <hch@lst.de> Reviewed-by: Dave Chinner <david@fromorbit.com>
| * xfs: fix bad_features2 fixups for the root filesystemChristoph Hellwig2009-01-18
| | | | | | | | | | | | | | | | | | | | | | | | | | Currently the bad_features2 fixup and the alignment updates in the superblock are skipped if we mount a filesystem read-only. But for the root filesystem the typical case is to mount read-only first and only later remount writeable so we'll never perform this update at all. It's not a big problem but means the logs of people needing the fixup get spammed at every boot because they never happen on disk.

| * xfs: fix dentry aliasing issues in open_by_handleChristoph Hellwig2009-01-18
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Open by handle just grabs an inode by handle and then creates itself a dentry for it. While this works for regular files it is horribly broken for directories, where the VFS locking relies on the fact that there is only just one single dentry for a given inode, and that these are always connected to the root of the filesystem so that it's locking algorithms work (see Documentations/filesystems/Locking) Remove all the existing open by handle code and replace it with a small wrapper around the exportfs code which deals with all these issues. At the same time we also make the checks for a valid handle strict enough to reject all not perfectly well formed handles - given that we never hand out others that's okay and simplifies the code.

The former takes vlan_mutex, and then might take RTNL via register_netdev()/unregister_netdev(). The latter is executed with RTNL held, and tries to take vlan_mutex, which can lead to an AB-BA deadlock. Fix this by having the child interface creation/deletion code take the RTNL first so vlan_mutex always nests inside RTNL. We can use register_netdevice() for child interfaces because we form the interface name from the parent interface and hence don't need the '%' expansion of register_netdev().

Switch from *_interruptible to *_killable on the sysfs- and procfs-related mutexes. This closes this possible can of worms.

The new subdriver is moslty a trimmed down copy of the wwan subdriver.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Store in firmware NVRAM the radio state on machine shutdown for WWAN and bluetooth. Also, try to set the initial boot state of these radios as the rfkill default state for their respective classes.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Instruct the firmware to not enable the radios when resuming. This is safer, and the rfkill core will take care to manually enable any radios that need to be enabled.

| | | * | | ACPI: thinkpad-acpi: debug facility to emulate the rf switchesHenrique de Moraes Holschuh2009-01-15

Add a debug facility to simulate an rfkill hardware rocker switch, a bluetooth rfkill soft-switch, a WWAN rfkill soft-switch on thinkpads. The simulated switches obviously do not kill any radios in hardware or firmware (unlike the real one). They also don't issue deprecated proc events.
