2009-01-14[CVE-2009-0029] System call wrapper special casesHeiko Carstens7-17/+106
System calls with an unsigned long long argument can't be converted with the standard wrappers since that would include a cast to long, which in turn means that we would lose the upper 32 bit on 32 bit architectures. Also semctl can't use the standard wrapper since it has a 'union' parameter. So we handle them as special case and add some extra wrappers instead.

2009-01-13Fix timeouts in sys_pselect7Bernd Schmidt1-1/+1
Since we (Analog Devices) updated our Blackfin kernel to 2.6.28, we've seen occasional 5-second hangs from telnet. telnetd calls select with a NULL timeout, but with the new kernel, the system call occasionally returns 0, which causes telnet to call sleep (5). This did not happen with earlier kernels. The code in sys_pselect7 looks a bit strange, in particular the variable "to" is initialized to NULL, then changed if a non-null timeout was passed in, but not used further. It needs to be passed to core_sys_select instead of &end_time. This bug was introduced by 8ff3e8e85fa6c312051134b3953e397feb639f51 ("select: switch select() and poll() over to hrtimers").

2009-01-13fix early_serial_setup() regressionHelge Deller2-1/+2
Commit b430428a188e8a434325e251d0704af4b88b4711 ("8250: Don't clobber spinlocks.") introduced a regression on the parisc architecture, which broke the handover to the serial port at boottime. early_serial_setup() was changed to only copy a subset of the uart_port fields, and sadly the "type" and "line" fields were forgotten and thus the serial port was not initialized and could not be used for a handover. This patch fixes this by copying the missing fields. As this change to early_serial_setup() doesn't need an initialized spinlock in the uart_port struct any longer, we can drop the spinlock initialization in the superio driver.

2009-01-13x86 PAT: return compatible mapping to remap_pfn_range callersvenkatesh.pallipadi@intel.com1-15/+28
Impact: avoid warning message, potentially solve 3D performance regression Change x86 PAT code to return compatible memtype if the exact memtype that was requested in remap_pfn_rage and friends is not available due to some conflict. This is done by returning the compatible type in pgprot parameter of track_pfn_vma_new(), and the caller uses that memtype for page table. Note that track_pfn_vma_copy() which is basically called during fork gets the prot from existing page table and should not have any conflict. Hence we use strict memtype check there and do not allow compatible memtypes. This patch fixes the bug reported here: http://marc.info/?l=linux-kernel&m=123108883716357&w=2 Specifically the error message: X:5010 map pfn expected mapping type write-back for d0000000-d0101000, got write-combining Should go away.

2009-01-12IPoIB: Do not join broadcast group if interface is brought downYossi Etigin1-0/+3
Because the ipoib_workqueue is not flushed when ipoib interface is brought down, ipoib_mcast_join() may trigger a join to the broadcast group after priv->broadcast was set to NULL (during cleanup). This will cause the system to be a member of the broadcast group when interface is down. As a side effect, this breaks the optimization of setting the Q_key only when joining the broadcast group.

2009-01-12ti_usb_3410_5052: support alternate firmwareChris Adams1-15/+29
The TI USB serial driver supports specifying alternate vendor and product IDs (since the chips can and are used in devices under other vendor/product IDs). However, the alternate IDs were not loaded in the combined product table. This patch also adds support for loading alternate firmware for alternate vendor/product IDs.

2009-01-12usb-serial: remove NULL checkAlan Cox1-3/+0
Julia Lawell found a case where a NULL check was misplaced in the usb-serial code. However as the object in question cannot be NULL the check can simply be removed. Signed-off-by: Alan Cox <alan@redhat.com> Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>
2009-01-12neo: Remove a bogus NULL checkAlan Cox1-3/+0
Julia Lawall found an un-needed check in the neo driver. Her patch moves the check to cover the code dereferencing it, however it cannot be NULL anyway so remove the NULL check instead. Signed-off-by: Alan Cox <alan@redhat.com> Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>
