Subject: [Bug 1923693] [NEW] Lack of architecture in gdbstub makes debugging confusing
Date: Wed, 14 Apr 2021 02:33:11 -0000 [thread overview]
Message-ID: <161836759211.17765.12297179006766447607.malonedeb@wampee.canonical.com> (raw)
Public bug reported:
I spent some quality time debugging GEF and came to a conclusion here:
https://github.com/hugsy/gef/issues/598#issuecomment-819174169
tldr;
* gdb_arch_name was undefined on riscv
* this bug was fixed recently via https://github.com/qemu/qemu/commit/edf647864bdab84ed4b1a4f47ea05be6bb075c69
* An undefined gdb_arch_name results in qemu's gdbstub omitting the <architecture> xml.
* gdb translates a missing <architecture> as "auto" which breaks a lot of stuff.
* tracking down where "auto" comes from is a bit confusing and time consuming.
It might be better to report a missing / blank gdb_arch_name as "<architecture>unknown</architecture>" instead of omitting the block completely.
