Subject: [PATCH 00/19] Signal mask for timer helper thread
Date: Tue, 19 May 2020 12:43:39 +0200 [thread overview]
Message-ID: <cover.1589884403.git.fweimer@redhat.com> (raw)
This series cleans up various aspects of NPTL and eventually adds
functionality to explicitly block internal signals on new threads.
There is now a proper public interface (for non-internal signals) and
the awkward separate sigset_t * argument and a pthread_create variant is
no longer needed.
To avoid creating new symbols in libpthread, some dependent
functionality had to be moved into libc. Since more parts of
pthread_attr_t are now dynamically allocated, it seemed prudent to
consolidate the copying of thread attributes.
Tested on x86_64-linux-gnu, i686-linux-gnu. Built with
build-many-glibcs.py (also various intermediate steps).
Thanks,
Florian
