Hi, Please find the rseq-enablement patchset for comments in this series. It has been modified following the discussions at the GNU Cauldron in Montreal this Fall. I will be on vacation for the next 2 weeks, so feedback from me may be delayed until early January 2020. This patch series is based on glibc master branch at commit a059f9505b tunables: report sbrk() failure Thanks for the feedback! Mathieu Florian Weimer (8): Introduce <elf_machine_sym_no_match.h> Implement __libc_early_init nptl: Start new threads with all signals blocked [BZ #25098] Linux: Add tables with system call numbers Linux: Use system call tables during build build-many-glibcs.py: Introduce LinuxHeadersPolicyForBuild build-many-glibcs.py: Introduce glibc build policy classes build-many-glibcs.py: Implement update-syscalls command Mathieu Desnoyers (5): glibc: Perform rseq(2) registration at C startup and thread creation (v13) glibc: sched_getcpu(): use rseq cpu_id TLS on Linux (v5) support record failure: allow use from constructor support: implement xpthread key create/delete (v3) rseq registration tests (v7) ChangeLog.old/ChangeLog.19 | 109 ++++ NEWS | 13 +- csu/init-first.c | 4 -
