Subject: [PATCH 0/4] Catch syscall groups
Date: Sun, 02 Nov 2014 19:36:00 -0000 [thread overview]
Message-ID: <1414956944-8856-1-git-send-email-gabriel@krisman.be> (raw)
Hello,
This patch series implements the ability to catch a group of related
syscalls with the catch syscall command. Basically, We separate
syscalls into syscall groups, such as 'network' and 'process' and let
users say something like "catch syscall group:<groupname>" to catch all
the system calls in the group at once.
For the record, I sent a RFC for this feature a few weeks ago. It can
be seen here
<https://www.sourceware.org/ml/gdb-patches/2014-10/msg00130.html>.
I followed the suggestions presented on that thread, and now we are
using the prefixes "group:" and "g:" to specify group names. So, these
syntaxes are allowed:
/* Catches network and process groups. */
$ catch syscall group:network group:process
$ catch syscall g:network g:process
Other than the usual word completion feature, this patch doesn't provide
a way to list all the groups available. This was discussed in the RFC
but we couldn't reach a consensus about the syntax. So, I am leaving it
to a future patch.
Right now, I created syscall groups only for the x86_64 architecture. I
sorted the syscalls following the same scheme strace does. I plan to
include support for other architectures as well, after getting this part
upstream.
This patch series is divided as follows: Part 1 updates the xml-syscall
interface to support the syscall group feature; Part 2 has the actual
catchpoint code; Part 3 has the updated x86_64 xml, which defines the
syscall groups for this architecture, and includes tests for this
feature on x86_64; Finally, Part 4 updates documentation and the NEWS
file.
This presented no regressions on Fedora 20 x86 and x86_64.
