<kerneltoast> fche, weekend's over
<kerneltoast> time to fix some bugsies
<kerneltoast> how much do you know about the uprobe code?
<fche> I have had that part of my brain surgically removed
<kerneltoast> can't remove what doesn't exist
<kerneltoast> in any case
<kerneltoast> "Error removing uprobe at pid 6577 vaddr 0x7ff5c1c42ee0: can't restore original instruction"
<kerneltoast> what does this mean to you
<fche> means the kernel is Not Happy
<fche> this is beneath systemtap's code base
<kerneltoast> we hit it on centos6 kernels
<kerneltoast> and i have no clue what it means
<fche> ah centos6
<fche> hm so that uprobe is our uprobe
<fche> well, other than this message ... is anything wrong?
<kerneltoast> the process dies from a SIGTRAP
orivej has joined #systemtap
<fche> no funeral dirge
<fche> mournful sigh
<kerneltoast> that process was like family to me
<kerneltoast> and now he's gone
<kerneltoast> fallen into a trap

<agentzh> fche: does the old centos6 utrace/uprobe patch support parallel probing on the same target process?
<agentzh> wondering if it's the parallell probing on the same target limitation.
<agentzh> glad the 7k kernel fuzzing indeed found some real stap bugs.
orivej has quit [Ping timeout: 256 seconds]
<agentzh> there are still 125 kernels with freezes/panics when running stap. they will need our investigations. most of them are from ubuntu 16.04's official repos. the rest are from other ubuntu and debian versions.
tromey has quit [Quit: ERC (IRC client for Emacs 27.1)]
<agentzh> so the red hat family should be clean now.
<agentzh> it takes a week to fuzz 7k+ kernels for a single round.
<agentzh> time to add more amd big boxes...
<agentzh> we currently only cover x86_64 kernels.
<agentzh> will take on aarch64 kernels soon.
irker224 has quit [Quit: transmission timeout]
<kerneltoast> fche, btw you should migrate the buildbots to parallel testing
<agentzh> good idea

<agentzh> fche: btw, thanks for the procfs fix. it's working for us now.
<fche> glad to hear
