2008-11-25hrtimer: removing all ur callback modesPeter Zijlstra9-293/+37
Impact: cleanup, move all hrtimer processing into hardirq context This is an attempt at removing some of the hrtimer complexity by reducing the number of callback modes to 1. This means that all hrtimer callback functions will be ran from HARD-irq context. I went through all the 30 odd hrtimer callback functions in the kernel and saw only one that I'm not quite sure of, which is the one in net/can/bcm.c - hence I'm CC-ing the folks responsible for that code. Furthermore, the hrtimer core now calls callbacks directly with IRQs disabled in case you try to enqueue an expired timer. If this timer is a periodic timer (which should use hrtimer_forward() to advance its time) then it might be possible to end up in an inf. recursive loop due to the fact that hrtimer_forward() doesn't round up to the next timer granularity, and therefore keeps on calling the callback - obviously this needs a fix. Aside from that, this seems to compile and actually boot on my dual core test box - although I'm sure there are some bugs in, me not hitting any makes me certain :-) Signed-off-by: Peter Zijlstra <a.p.zijlstra@chello.nl> Signed-off-by: Ingo Molnar <mingo@elte.hu>

2008-11-20[IA64] Rationalize kernel mode alignment checkingTony Luck2-1/+2
Itanium processors can handle some misaligned data accesses. They also provide a mode where all such accesses are forced to trap. The kernel was schizophrenic about use of this mode: * Base kernel code ran in permissive mode where the only traps generated were from those cases that the h/w could not handle. * Interrupt, syscall and trap code ran in strict mode where all unaligned accesses caused traps to the 0x5a00 unaligned reference vector. Use strict alignment checking throughout the kernel, but make sure that we continue to let user mode use more relaxed mode as the default. Signed-off-by: Tony Luck <tony.luck@intel.com>
2008-11-20x86: Fix interrupt leak due to migrationMatthew Wilcox1-0/+14
When we migrate an interrupt from one CPU to another, we set the move_in_progress flag and clean up the vectors later once they're not being used. If you're unlucky and call destroy_irq() before the vectors become un-used, the move_in_progress flag is never cleared, which causes the interrupt to become unusable. This was discovered by Jesse Brandeburg for whom it manifested as an MSI-X device refusing to use MSI-X mode when the driver was unloaded and reloaded repeatedly.

2008-11-20SUNRPC: Fix a performance regression in the RPC authentication codeTrond Myklebust1-2/+18
Fix a regression reported by Max Kellermann whereby kernel profiling showed that his clients were spending 45% of their time in rpcauth_lookup_credcache. It turns out that although his processes had identical uid/gid/groups, generic_match() was failing to detect this, because the task->group_info pointers were not shared. This again lead to the creation of a huge number of identical credentials at the RPC layer. The regression is fixed by comparing the contents of task->group_info if the actual pointers are not identical.

But since translate_usr_offset() returns -1 for invalid offsets, addr can now get the value 0xffffffff which then fails the next return-value sanity check and thus the kernel tries to access invalid memory: if (addr < 0) break; Fix this bug by modifying translate_usr_offset() to take and return values of type compat_ulong_t, and by returning the value "sizeof(struct pt_regs)" as an error indicator. Additionally change the sanity check to check for return values for >= sizeof(struct pt_regs). This patch survived my compile and run-tests.

2008-11-20[CIFS] Do not attempt to close invalidated file handlesSteve French4-9/+30
If a connection with open file handles has gone down and come back up and reconnected without reopening the file handle yet, do not attempt to send an SMB close request for this handle in cifs_close. We were checking for the connection being invalid in cifs_close but since the connection may have been reconnected we also need to check whether the file handle was marked invalid (otherwise we could close the wrong file handle by accident).

2008-11-20TPROXY: fill struct flowi->flags in udp_sendmsg()Balazs Scheidler1-0/+1
udp_sendmsg() didn't fill struct flowi->flags, which means that the route lookup would fail for non-local IPs even if the IP_TRANSPARENT sockopt was set. This prevents sendto() to work properly for UDP sockets, whereas bind(foreign-ip) + connect() + send() worked fine. Signed-off-by: Balazs Scheidler <bazsi@balabit.hu> Signed-off-by: David S.

2008-11-19USB: usbmon: fix read(2)Pete Zaitcev1-1/+4
There's a bug in the usbmon binary reader: When using read() to fetch the packets and a packet's data is partially read, the next read call will once again return up to len_cap bytes of data. The b_read counter is not regarded when determining the remaining chunk size. So, when dumping USB data with "cat /dev/usbmon0 > usbmon.trace" while reading from a USB storage device and analyzing the dump file afterwards it will get out of sync after a couple of packets.

2008-11-19USB: gadget rndis: send notificationsRichard Röjfors1-1/+1
It turns out that atomic_inc_return() returns the *new* value not the original one, so the logic in rndis_response_available() kept the first RNDIS response notification from getting out. This prevented interoperation with MS-Windows (but not Linux). Fix this to make RNDIS behave again.

2008-11-19USB: gadget rndis: stop windows self-immolationDavid Brownell1-1/+0
Somewhere in the conversion of the RNDIS gadget code to the new framework, the descriptor of its data interface seems to have been copied from the CDC Ethernet driver. Unfortunately that means it got a nonzero altsetting ... which is incorrect. Issue uncovered by Richard Röjfors <richard.rojfors@endian.se>. This patch fixes that problem, and resolves at least some cases of Windows XP bluescreening itself. Tested-by: Richard Röjfors <richard.rojfors@endian.se>.

This patch (as1168) updates the unusual_devs entry for the Nokia 5300. According to Jorge Lucangeli Obes <t4m5yn@gmail.com>, some existing models have a revision number lower than the lower limit of the current entry. The patch also moves the entry for the Nokia 5310 to its correct place in the file. Signed-off-by: Alan Stern <stern@rowland.harvard.edu> Signed-off-by: Greg Kroah-Hartman <gregkh@suse.de>

2008-11-19USB: fix SB700 usb subsystem hang bugAndiry Xu1-0/+21
This patch is required for AMD SB700 south bridge revision A12 and A13 to avoid USB subsystem hang symptom. The USB subsystem hang symptom is observed when the system has multiple USB devices connected to it. In some cases a USB hub may be required to observe this symptom. This patch works around the problem by correcting the internal register setting that will help by changing the behavior of the internal logic to avoid the USB subsystem hang issue. The change in the behavior of the logic does not impact the normal operation of the USB subsystem.
