These patches contain the following linux kernel bug fixes:

Description:

kernel: ptrace peek and poke interface.

Symptom:

ptrace poke on a 64 bit system on acrs[15] or fpc register can crash the kernel.

Problem:

The special cases of peek and poke on acrs[15] and the fpc register are not handled correctly. A poke on acrs[15] will clobber the 4 bytes after the access registers in the thread_info structure. That happens to be the kernel stack pointer. A poke on the fpc with an invalid value is not caught by the validity check correctly. On the next context switch the broken fpc value will cause a program check in the kernel.

Solution:

Correctly handle the special cases for acrs[15] and fpc.

Problem-ID:

15792

Note:

applicable for 64-bit Linux, only

Description:

kernel: user access context check.

Symptom:

Console message "bad: scheduling while atomic!".

Problem:

A kernel compiled with preemption sometimes prints a message on the console about bad scheduling. That happens if the interrupted context was disabled for preemption. The check for no context in do_exception on checks for hard and soft interrupts by using in_interrupt() but not for preemption.

Solution:

Use in_atomic() instead of in_interrupt() in do_exception. in_atomic checks for disabled preemption as well.

Problem-ID:

15294

Description:

qeth: dhcp does not work with qdio HSTR (high speed token ring).

Symptom:

dhcp client does not get IP configuration data from the dhcp server, when qeth runs in layer 3 mode.

Problem:

Fake_ll is not implemented for HSTR. Token ring packages got leading ethernet header, which was not correct.

Solution:

Implement fake_ll for HSTR. Now all token ring packages get a faked token ring header.

Problem-ID:

15734
