Status: NEW
Severity: normal
Priority: P2
Component: runtime
Assignee: systemtap at sourceware dot org

Target Milestone: ---
Analysis of the systemtap buildbot data shows the following regressions

- breakage in at_deref.exp
FAIL: at_uderef unexpected output
after a790dc6 PR27251: support buildid probing on --x--x--x perm binaries
or ea81249 PR27273: port to linux 5.11
(exact location unclear)
- breakage in at_var_mark,at_var_mark_func,at_var_pie,at_var_timer_profile
- more breakage in at_deref.exp
FAIL: at_var_mark unexpected output
FAIL: at_var_mark_func startup (eof)
FAIL: at_var_pie
after cd7b3e0 PR27030 bpf/uconversions.stp: other sizes user_*_error()

executable

--- Comment #2 from Serhei Makarov <me at serhei dot io> ---
after more investigation of the data
15:53 < fche> serhei, and do I remember correctly that your tool associated
these test cases with
the previous relocation-related change that kerneltoast is about
to revise?
15:56 < serhei> which commit id was that change in?
15:56 < fche> d1b554876c68f3
15:58 < serhei> interesting
15:58 < serhei> that's associated with a regression in a different set of
testcases
15:58 < serhei> namely exelib.exp, usymbols.exp, sdt_global_var.exp
15:58 < serhei> + process-begin-user.exp
15:59 < serhei> ah, and also the at_var_* cases documented in the PR
