2010-12-01genirq: Fix incorrect proc spurious outputKenji Kaneshige
Since commit a1afb637(switch /proc/irq/*/spurious to seq_file) all /proc/irq/XX/spurious files show the information of irq 0. Current irq_spurious_proc_open() passes on NULL as the 3rd argument, which is used as an IRQ number in irq_spurious_proc_show(), to the single_open(). Because of this, all the /proc/irq/XX/spurious file shows IRQ 0 information regardless of the IRQ number. To fix the problem, irq_spurious_proc_open() must pass on the appropreate data (IRQ number) to single_open().

2010-11-30Input: add keycodes for touchpad on/off keysBastien Nocera
Some laptops will have a "touchpad toggle" soft button, which expects user-space to turn off the touchpad themselves, some other devices will do this in hardware, but send key events telling us that the touchpad has been turned off/on. KEY_TOUCHPAD_ON/KEY_TOUCHPAD_OFF will be used by user-space to show a popup with the status of the touchpad.

2010-12-01sh: Assume new page cache pages have dirty dcache lines.Paul Mundt
This follows the ARM change c01778001a4f5ad9c62d882776235f3f31922fdd ("ARM: 6379/1: Assume new page cache pages have dirty D-cache") for the same rationale: There are places in Linux where writes to newly allocated page cache pages happen without a subsequent call to flush_dcache_page() (several PIO drivers including USB HCD). This patch changes the meaning of PG_arch_1 to be PG_dcache_clean and always flush the D-cache for a newly mapped page in update_mmu_cache(). This addresses issues seen with executing binaries from MMC, in addition to some of the other HCDs that don't explicitly do cache management for their pipe-in buffers.

2010-11-30sparc: Write to prom console using indirect buffer.David S. Miller
sparc64 systems have a restriction in that passing in buffer addressses above 4GB to prom calls is not reliable. We end up violating this when we do prom console writes, because we use an on-stack buffer to translate '\n' into '\r\n'. So instead, do this translation into an intermediate buffer, which is in the kernel image and thus below 4GB, then pass that to the PROM console write calls. On the 32-bit side we don't have to deal with any of these issues, so the new prom_console_write_buf() uses the existing prom_nbputchar() implementation. However we can now mark those routines static. Since the 64-bit side completely uses new code we can delete the putchar bits as they are now completely unused. Signed-off-by: David S.

2010-11-30exec: copy-and-paste the fixes into compat_do_execve() pathsOleg Nesterov
Note: this patch targets 2.6.37 and tries to be as simple as possible. That is why it adds more copy-and-paste horror into fs/compat.c and uglifies fs/exec.c, this will be cleanuped later. compat_copy_strings() plays with bprm->vma/mm directly and thus has two problems: it lacks the RLIMIT_STACK check and argv/envp memory is not visible to oom killer. Export acct_arg_size() and get_arg_page(), change compat_copy_strings() to use get_arg_page(), change compat_do_execve() to do acct_arg_size(0) as do_execve() does. Add the fatal_signal_pending/cond_resched checks into compat_count() and compat_copy_strings(), this matches the code in fs/exec.c and certainly makes sense.

2010-11-30exec: make argv/envp memory visible to oom-killerOleg Nesterov
Brad Spengler published a local memory-allocation DoS that evades the OOM-killer (though not the virtual memory RLIMIT): http://www.grsecurity.net/~spender/64bit_dos.c execve()->copy_strings() can allocate a lot of memory, but this is not visible to oom-killer, nobody can see the nascent bprm->mm and take it into account. With this patch get_arg_page() increments current's MM_ANONPAGES counter every time we allocate the new page for argv/envp. When do_execve() succeds or fails, we change this counter back. Technically this is not 100% correct, we can't know if the new page is swapped out and turn MM_ANONPAGES into MM_SWAPENTS, but I don't think this really matters and everything becomes correct once exec changes ->mm or fails.

2010-11-30cifs: fix parsing of hostname in dfs referralsJeff Layton
The DFS referral parsing code does a memchr() call to find the '\\' delimiter that separates the hostname in the referral UNC from the sharename. It then uses that value to set the length of the hostname via pointer subtraction. Instead of subtracting the start of the hostname however, it subtracts the start of the UNC, which causes the code to pass in a hostname length that is 2 bytes too long.

(the correct SA/TA would be: 00:1f:31:f8:64:ff) Since the AP does not know from where the frames come, it generates a DEAUTH response for the (invalid) mcast address. This mcast deauth frame then passes through all filters and tricks the stack into thinking that the AP brutally kicked us! This patch fixes the problem by simply ignoring non-broadcast, group-addressed deauth/disassoc frames.

If a 32bit CUSE server is run on 64bit this results in EIO being returned to the caller. The reason is that FUSE_IOCTL_RETRY reply was defined to use 'struct iovec', which is different on 32bit and 64bit archs. Work around this by looking at the size of the reply to determine which struct was used. This is only needed if CONFIG_COMPAT is defined.

Fix kernel-doc warning for set_consumer_device_supply(): Warning(drivers/regulator/core.c:912): missing initial short description on line: * set_consumer_device_supply: Bind a regulator to a symbolic supply Signed-off-by: Randy Dunlap <randy.dunlap@oracle.com> Cc: Liam Girdwood <lrg@slimlogic.co.uk> Cc: Mark Brown <broonie@opensource.wolfsonmicro.com> Acked-by: Mark Brown <broonie@opensource.wolfsonmicro.com> Signed-off-by: Liam Girdwood <lrg@slimlogic.co.uk>
2010-11-30regulator: enable supply regulator only when use count is zeroBengt Jonsson
Supply regulators are disabled only when the last reference count is removed on the child regulator (the use count goes from 1 to 0). This patch changes the behaviour of enable so the supply regulator is enabled only when the use count of the child regulator goes from 0 to 1.

2010-11-30regulator: twl-regulator - fix twlreg_set_modeAxel Lin
The Singular Message is 16 bits: DEV_GRP[15:13] MT[12] RES_ID[11:4] RES_STATE[3:0] Current implementation return immedially after sucessfuly write MSB part. To properly set mode, we need to write the complete message ( MSB and LSB ). In twl.h, now we have defines for PM Master module register offsets, use it instead of hard coded 0x15/0x16. Use "message & 0xff" to ensure we send correct value for LSB.
