linux-2.4.21-s390-32-june2003.tar.gz / MD5 ... accumulated patch, recommended (2006-03-08)

linux-2.4.21-s390-32-june2003-patches.tar.gz / MD5 ... per-problem-patches, recommended (2006-03-08)

These patches contain the following linux kernel bug fixes:

Description:

kernel: magic sysrq-t addressing exception.

Symptom:

Kernel hangs after the magic sysrq key "t" is submitted.

Problem:

The show_task function walks the kernel stack backchain of processes assuming that the processes are not running. Since this assumption is not correct walking the backchain can lead to an addressing exception and therefore to a kernel hang.

Solution:

Verify that all read accesses are within the bounds of the kernel stack before performing them.

Problem-ID:

20475

Description:

lcs: LCS device drops too many packets on a flood ping.

Symptom:

Significant drop count increase when flood ping is running.
Ping program reports 90% packet loss.

Problem:

Number of LCS send buffers is too small.
Netif_stop_queue has not been issued in LCS send routine.

Solution:

Number of LCS send buffers increased to 32.
Call netif_stop_queue when sending a packet.

Problem-ID:

17612

Everybody should apply this patch.
