Subject: [PATCH 0/6] Improve ptrace-error detection
Date: Wed, 26 Feb 2020 20:06:00 -0000 [thread overview]
Message-ID: <20200226200542.746617-1-sergiodj@redhat.com> (raw)
In-Reply-To: <20190926042155.31481-1-sergiodj@redhat.com>
This patch series is the continuation of:
[PATCH v5] Improve ptrace-error detection on Linux targets
https://sourceware.org/ml/gdb-patches/2019-09/msg00504.html
I decided to start a new series because this involved a rewrite of
several parts of the patch. I addressed all of the comments I
received back in September (mostly from Pedro), but I also did some
improvements, especially in the 'fork_inferior' code.
After submitting this series to our Buildbot, no regressions were
found.
Sergio Durigan Junior (6):
Introduce scoped_pipe.h
Don't reset errno/bfd_error on 'throw_perror_with_name'
Expand 'fork_inferior' to check whether 'traceme_fun' succeeded
Extend GNU/Linux to check for ptrace error
Document Linux-specific possible ptrace restrictions
Fix comment for 'gdb_dlopen'
