Gabi Falk ca70c8f0b3 rt_sigreturn: emit argument name for sigmask under -N
The rt_sigreturn(2) decoder printed the synthesized sigmask value via
print_sigset_addr() without a leading "sigmask=", so -N/--arg-names
output lacked the label other syscalls have.

* src/rt_sigreturn.c (SYS_FUNC(rt_sigreturn)): Add
tprints_arg_name("sigmask") before print_sigset_addr().

strace - the linux syscall tracer

This is strace -- a diagnostic, debugging and instructional userspace utility with a traditional command-line interface for Linux. It is used to monitor and tamper with interactions between processes and the Linux kernel, which include system calls, signal deliveries, and changes of process state. The operation of strace is made possible by the kernel feature known as ptrace.

strace is released under the terms of the GNU Lesser General Public License version 2.1 or later; see the file COPYING for details. strace test suite is released under the terms of the GNU General Public License version 2 or later; see the file tests/COPYING for details.

See the file NEWS for information on what has changed in recent versions.

Please read the file INSTALL-git for installation instructions.

Please take a look at the guide for new contributors if you want to get involved in strace development.

The user discussion and development of strace take place on the strace mailing list -- everyone is welcome to post bug reports, feature requests, comments and patches to strace-devel@lists.strace.io. The mailing list archives are available at https://lists.strace.io/pipermail/strace-devel/ and other archival sites.

The GIT repository of strace is available at GitHub and GitLab.

Strace packages are available downstream in many repositories.
