Subject: [Bug runtime/27224] stap 4.4 'cannot attach to module' in debugfs mode as non-root
Date: Fri, 22 Jan 2021 04:31:12 +0000	[thread overview]
Message-ID: <bug-27224-6586-jPwvzzOX4K@http.sourceware.org/bugzilla/> (raw)

--- Comment #2 from Craig Ringer <craig.ringer at 2ndquadrant dot com> ---
Created attachment 13144
  --> https://sourceware.org/bugzilla/attachment.cgi?id=13144&action=edit
stap -vvvv -DSTAP_TRANS_DEBUGFS output

Output from

  $ sudo mount /sys/kernel/debug -o remount,mode=700

  $ stap -vvvv -DSTAP_TRANS_DEBUGFS -e 'probe begin { printf("started\n");
exit(); }'

on stap 4.4 from systemtap-4.4-2.fc33.x86_64 

I filtered it with 

  egrep -v '^(Skipping tapset|Processing)'

to reduce irrelevant spam.
