timeout in eppic.mk
by Karlsson, Jan
Hi Dave
When I build crash, including the extension directory, I get a "Connection timeout" for the git clone command in eppic.mk. For some reason this command fails in my environment. As this timeout is 10 minutes I just wonder if it is possible to make some change in the make file to avoid this waiting time. I could of course remove the eppic extension but I want to make as few changes in the file structure for crash as possible.

[PATCH] netdump, diskdump: address the issue caused by no NT_PRSTATUS notes
by HATAYAMA Daisuke
Hello Dave,
I have three patches today.
The 1st and 2nd patches address the issue that vmcore has no NT_PRSTATUS
notes.
- The 1st patch makes crash consider the case where the number of
NT_PRSTATUS notes
is 0. Without this patch, crash leads to NULL pointer dereference when
using bt
command for active tasks.
- The 2nd patch makes crash pass boot-time sanity check to nr_cpus
memebr of diskdump
header on x86 and x86_64 if it is 0. On both architectures, we can get cpu
information from memory part. In fact, the value of nr_cpus member is
not used
except for the sanity check.
I saw the situation where vmcore with no NT_PRSTATUS notes is generated,
on Xen HVM,
where the version of kexec not supporting Xen HVM. It determins if
system is Xen Dom0
wrongly and uses interface for Dom0. As a result, vmcore doesn't contain any
NT_PRSTATUS note.
When converting this vmcore using makedumpfile, nr_cpus member of
diskdump header of
the resulted vmcore is 0. So the 2nd patch is needed.
The 3rd patch is differnet from the above two, fixing potencial bug in
panic task
detection code, which I found during investigation for the above two
patches.
But sorry, I didn't test this yet.
I made every patch on top of crash version 6.1.0.
Thanks.
