igb: Fix lack of flush after register write and before delay

2011-08-29T21:08:09+00:00

commit 064b43304ed8ede8e13ff7b4338d09fd37bcffb1 upstream. Register writes followed by a delay are required to have a flush before the delay in order to commit the values to the register. Without the flush, the code following the delay may not function correctly.

commit 7c4c3960dff109bc5db4c35da481c212dadb5eb5 upstream. ttm_tt_destroy kfrees passed object, so we need to nullify a reference to it. Signed-off-by: Marcin Slusarz Reviewed-by: Thomas Hellstrom Signed-off-by: Dave Airlie Signed-off-by: Greg Kroah-Hartman

hwmon: (ibmaem) add missing kfree

2011-08-29T21:08:04+00:00

commit 66a89b2164e2d30661edbd1953eacf0594d8203a upstream. rs_resp is dynamically allocated in aem_read_sensor(), so it should be freed before exiting in every case. This collects the kfree and the return at the end of the function. Signed-off-by: Julia Lawall Signed-off-by: Guenter Roeck Signed-off-by: Greg Kroah-Hartman

USB: usb-storage: unusual_devs entry for ARM V2M motherboard.

2011-08-29T21:08:02+00:00

commit a871e4f5519d8c52430052e1d340dd5710eb5ad6 upstream. Connecting the V2M to a Linux host results in a constant stream of errors spammed to the console, all of the form sd 1:0:0:0: ioctl_internal_command return code = 8070000 : Sense Key : 0x4 [current] : ASC=0x0 ASCQ=0x0 The errors appear to be otherwise harmless. Add an unusual_devs entry which eliminates all of the error messages. Signed-off-by: Nick Bowler Acked-by: Alan Stern Signed-off-by: Greg Kroah-Hartman

net: Compute protocol sequence numbers and fragment IDs using MD5.

2011-08-16T01:57:20+00:00

Computers have become a lot faster since we compromised on the partial MD4 hash which we use currently for performance reasons. MD5 is a much safer choice, and is inline with both RFC1948 and other ISS generators (OpenBSD, Solaris, etc.) Furthermore, only having 24-bits of the sequence number be truly unpredictable is a very serious limitation. So the periodic regeneration and 8-bit counter have been removed. We compute and use a full 32-bit sequence number. For ipv6, DCCP was found to use a 32-bit truncated initial sequence number (it needs 43-bits) and that is fixed here as well.
