1) Three bluetooth regression fixes from Marcel Holtmann. 2) In 2.6.27 we added a faster and more reliable IPSEC policy and state dumping mechanism, but this new code leaves out larval and socket local policies which is an unintended user visible change. Fixed by Herbert Xu. 3) As per kernel bugzilla, ip6_dst_lookup_tail() can OOPS when the optimistic DAD config option is enabled because said code assumes there is always a neighbour attached to a route at this point, but th...

Tejun's commit 7b595756ec1f49e0049a9e01a1298d53a7faaa15 made sysfs attribute->owner unnecessary. But the field was left in the structure to ease the merge. It's been over a year since that change and it is now time to start killing attribute->owner along with its users - one arch at a time! This patch is attempt #1 to get rid of attribute->owner only for CONFIG_X86_64 or CONFIG_X86_32 . We will deal with other arches later on as and when possible - avr32 will be the next since that is som...

Hi, Last week, the subvolumes feature was dropped from Tux3. I thought it would be worth explaining why, because it says something about the Tux3 design philosophy and the direction I think we ought to be headed. A subvolume is a separately mountable filesystem that coexists with other subvolumes in a single, physical volume. For a tree-structured filesystem, which is to say, nearly every modern filesystem, having subvolumes just requires adding more tree roots. Nothing could be simpler, righ...

From: Alexander van Heukelum <heukelum@fastmail.fm> x86_64 handles all exceptions with interrupts off initially, this bisectable patch set does the same for i386, in (very) small steps.

From: Alexander van Heukelum <heukelum@fastmail.fm> There is some macro magic in traps_32.c to construct standard exception dispatch functions. This patch renames the DO_ERROR- like macros to DO_TRAP, and introduces new DO_ERROR ones that conditionally reenable interrupts explicitly, like x86_64. No code changes.

From: Alexander van Heukelum <heukelum@fastmail.fm> The int3 exception was already takes as an interrupt and do_int3 does not fit in the new DO_ERROR macro. This patch just expands the DO_TRAP macro and rearranges the code a bit. No functional changes intended.

What's the proprietary module that's tainting it? Ideally we'd like to see it reproduced on an untainted kernel, but depending on what it is, it may not matter. When you say you're not able to log in, is that because the keyboard is unresponsive? It appears to be affecting USB, so I'd be curious to know if you can ssh into the box, or log in with a PS/2 keyboard. Of course, some PS/2 ports are connected via USB under the hood, so the keyboard might not tell us much. -- Chris --
