These patches contain the following linux kernel bug fixes:

Description:

kernel: user readable uninitialized kernel memory.

Symptom:

None.

Problem:

A user space program can read uninitialized kernel memory by appending to a file from a bad address and then reading the result back. The cause is the copy_from_user function that does not clear the remaining bytes of the kernel buffer after it got a fault on the user space address.

Solution:

Fix the copy_from_user function to clear the remaining bytes of the kernel buffer after a user space fault.

Problem-ID:

27706

Description:

qeth: stack trace with msg 'inconsistent lock state'.

Symptom:

messages

[ INFO: inconsistent lock state ]
inconsistent {in-softirq-W} -> {softirq-on-W} usage.
modprobe/758 [HC0[0]:SC0[0]:HE1:SE1] takes:
(&tbl->lock){-+-.}, at: [<000000008080c396>].
qeth_init+0x396/0x4e4 [qeth]

Problem:

This was discovered on a higher kernel level using the service 'Lock dependency validator'.

Solution:

bhs must be disabled when accessing neighbor tables.

Problem-ID:

26014
