Re: [Crash-utility] loop in crash
Hi
and thanks for your work with this problem.
As you expected crash silently just loops and I spotted the problem by turning on debug
printouts.
If I include printouts for the "cache" address, the first value seems
reasonable, but then it starts to repeat with the value 0x00000001.
Last, your patch solves the problem nicely. I get a warning about duplicate kmem_slab
entry and crash continues to execute and issues other warnings indicating a corrupt vmcore
file.

So I don't understand how you got into a loop unless the kmem_cache
list walk-through is the real problem. If you were to print out the "cache"
address each time through the do-while loop, does the list start
repeating itself?
And if that's true, perhaps the kmem_cache_init() should use the
hq_open()/hq_enter()/hq_close() facility on each cache address to
catch a duplicate (false) entry.
And if that's true, does the attached patch help?
Thanks,
Dave
