ARM: 6891/1: prevent heap corruption in OABI semtimedop

2012-02-11T14:37:17+00:00

commit 0f22072ab50cac7983f9660d33974b45184da4f9 upstream. When CONFIG_OABI_COMPAT is set, the wrapper for semtimedop does not bound the nsops argument. A sufficiently large value will cause an integer overflow in allocation size, followed by copying too much data into the allocated buffer. Fix this by restricting nsops to SEMOPM. Untested.

ARM: Ensure predictable endian state on signal handler entry

2011-04-30T14:53:07+00:00

commit 53399053eb505cf541b2405bd9d9bca5ecfb96fb upstream. Ensure a predictable endian state when entering signal handlers. This avoids programs which use SETEND to momentarily switch their endian state from having their signal handlers entered with an unpredictable endian state.

ARM: 6482/2: Fix find_next_zero_bit and related assembly

2010-12-09T21:24:19+00:00

commit 0e91ec0c06d2cd15071a6021c94840a50e6671aa upstream. The find_next_bit, find_first_bit, find_next_zero_bit and find_first_zero_bit functions were not properly clamping to the maxbit argument at the bit level. They were instead only checking maxbit at the byte level. To fix this, add a compare and a conditional move instruction to the end of the common bit-within-the- byte code used by all the functions and be sure not to clobber the maxbit argument before it is used.

ARM: Add i2c_board_info for RiscPC PCF8583

2009-03-17T00:53:03+00:00

commit 531660ef5604c75de6fdead9da1304051af17c09 upstream Add the necessary i2c_board_info structure to fix the lack of PCF8583 RTC on RiscPC. Signed-off-by: Russell King Signed-off-by: Jean Delvare Cc: Alessandro Zummo Signed-off-by: Greg Kroah-Hartman

Rename old_readdir to sys_old_readdir

commit e55380edf68796d75bf41391a781c68ee678587d upstream. This way it matches the generic system call name convention. Signed-off-by: Heiko Carstens Signed-off-by: Greg Kroah-Hartman

ARM: 5329/1: Feroceon: fix feroceon_l2_inv_range

2008-11-20T22:54:43+00:00

commit 72bc2b1ad62f4d2f0a51b35829093d41f55accce upstream. Same fix as commit c7cf72dcadb: when 'start' and 'end' are less than a cacheline apart and 'start' is unaligned we are done after cleaning and invalidating the first cacheline.

ARM: 5300/1: fixup spitz reset during boot

2008-11-13T17:56:03+00:00

commit 69fc7eed5f56bce15b239e5110de2575a6970df4 upstream Some machines don't have the pullup/down on their reset pin, so configuring the reset generating pin as input makes them reset immediately. Fix that by making reset pin direction configurable.

ARM: xsc3: fix xsc3_l2_inv_range

2008-11-13T17:55:58+00:00

commit c7cf72dcadbe39c2077b32460f86c9f8167be3be upstream When 'start' and 'end' are less than a cacheline apart and 'start' is unaligned we are done after cleaning and invalidating the first cacheline. So check for (start < end) which will not walk off into invalid address ranges when (start > end). This issue was caught by drivers/dma/dmatest. 2.6.27 is susceptible.
