Around a year and a half ago, I’ve asked my former company for some time to
work on an issue that was impacting the debugging capabilities in our project:
gdbserver couldn’t debug multithreaded applications running on a PowerPC32
architecture. The connection to the gdbserver was broken and it couldn’t
control the debug session anymore. Multiple people have already investigated
this problem and I had a good starting point, but we still weren’t sure in
which software component the issue lied: it could have been the toolchain, the
gdbserver, the Linux kernel or the custom patches we applied on top of the
kernel tree. We were quite far away from finding the root cause.
You did receive credit. A good bug report allows reproducing and ideally fixing the issue - which can involve considerable effort. This is the difference between your report, and the one you linked from 6 years ago.
Like I said, I'd probably have added an additional thanks for that in my commit message - but I'm unfamiliar with the kind of reports this particular subsystem typically receives, so it is quite possible your report is just something average coming in there.
I personally prefer to include code suggesting a fix in my bug reports - but I usually don't expect it to be just merged as I'm not familiar with surrounding code. I also don't expect that to receive an additional mention - it's just part of the report, and is often cleaner in demonstrating the issue than a problem description.
