Package: bpftrace
Version: 0.11.3-2
Severity: wishlist
X-Debbugs-Cc: john.ogn...@linutronix.de
Dear Maintainer,
In order for bpftrace to support setting uprobes by address/offset, the build
dependency libbfd-dev must be added. Otherwise uprobes are limited to symbols,
which in many cases is not sufficient for debugging live systems.
Example:
# bpftrace -e 'uprobe:/root/hello:0x1139 { print(nsecs); }'
Attaching 1 probe...
Can't check if uprobe is in proper place (compiled without (k|u)probe offset
support): /root/hello:main+4
When bpftrace is built with libbfd-dev as a build dep:
# bpftrace -e 'uprobe:/root/hello:0x1139 { print(nsecs); }'
Attaching 1 probe...

^C
Please consider making this simple change to allow full uprobe support.
Thank you.
John Ogness
