| * [POWERPC] ppc32: Fix errata for 603 CPUsKumar Gala2008-04-211-1/+7
| | | | | | | | | | | | | | | | | | | | 603 CPUs have the same issue that some 750 CPUs have in that they can crash in funny ways if a store from an FPU register instruction is executed on a register that has never been initialized since power on. This patch fixes it by making sure all FP registers have been properly initialized at kernel boot. Signed-off-by: Kumar Gala <galak@kernel.crashing.org>

| | | | | | | | | | | | | | | | | | | | | | | | | | Since 43cc71eed1250755986da4c0f9898f9a635cb3bf, the platform modalias is prefixed with "platform:". Add MODULE_ALIAS() to the hotpluggable "macintosh" platform drivers, to re-enable auto loading.

Code shared between /proc/<pid>/mounts and /proc/<pid>/mountinfo is extracted into separate functions. Thanks to Al Viro for the help in getting the design right.

The identifiers are reused after the peer group dissolves. The IDR structures are protected by holding namepspace_sem for write while allocating or deallocating IDs. IDs are allocated when a previously unshared vfsmount becomes the first member of a peer group. When a new member is added to an existing group, the ID is copied from one of the old members. IDs are freed when the last member of a peer group is unshared. Setting the MNT_SHARED flag on members of a subtree is done as a separate step, after all the IDs have been allocated. This way an allocation failure can be cleaned up easilty, without affecting the propagation state. Based on design sketch by Al Viro.

| * | | [IPSEC]: Fix catch-22 with algorithm IDs above 31Herbert Xu2008-04-224-2/+7

It just happens to work on x86 but fails miserably on ppc64. The reason is that we're using a bit mask to check the algorithm ID but the mask is only 32 bits wide. After looking at how this is used in the field, I have concluded that in the long term we should phase out state matching by IDs because this is made superfluous by the reqid feature. For current applications, the best solution IMHO is to allow all algorithms when the bit masks are all ~0. The following patch does exactly that. This bug was identified by IBM when testing on the ppc64 platform using the NULL authentication algorithm which has an ID of 251.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The del_timer() function doesn't guarantee, that the timer callback is not active by the time it exits. Thus, the fib6_net_exit() may kfree() all the data, that is required by the fib6_run_gc(). The race window is tiny, but slab poisoning can trigger this bug. Using del_timer_sync() will cure this.

That way we know that umount_tree(), copy_tree() and clone_mnt() are _always_ serialized by namespace_sem. umount_tree() still needs vfsmount_lock (it manipulates hash chains, among other things), but that's a separate story.

This fixes it and clarifies the code a bit too (we used to have to use the insane PCI bridge alignment logic that put the alignment in the "start" field, this makes it use the slightly easier-to-understand size-based alignment, and allows us to set the resource start to zero until it gets allocated).
