Hi Anton,
Unfortunately it's still crashing. The log is below, but to make
sure I'm not deluding myself, the source tree is
https://github.com/blackgnezdo/src/tree/anton-kcov-dec1
This is the workdir where I'm building:
commit fea58d64a837907fd3b5c45eb2b77351ac105d5f (HEAD -> anton-kcov-dec1)
SYZKALLER.MP conf
commit 583b85f9857e44ee3339d9bb74e2780e435e3937 (origin/anton-kcov-dec1)
anton@: disable kcov in files incompatible with tracing
By performing a semi-automated bisect I was able to identify the source
files that are incompatible with tracing. Common for all source files
seems to be that they define routines called early on in the boot
process before curcpu() is usable.
commit 3f7c3e6a6fe644f1ab7c92ea63819fb056a99f6d
regen
Happy to test more patches. The easiest for me would be to merge
them as PRs into my github tree, but I'm happy to keep applying
them manually if it's more convenient for you.
