Hi,
Please find the rseq-enablement patchset for comments in this series.
This patch series is based on glibc master branch at commit
1fabdb9908 x86: Remove ARCH_CET_LEGACY_BITMAP [BZ #25397]
Since the last post:
- Move elf/elf_machine_sym_no_match.h to sysdeps/generic (additional
patch).
- Move NEWS entry under 2.32.
- Move new __rseq_abi symbol to GLIBC_2.32.
Please consider for merging into glibc.
Mathieu
Florian Weimer (3):
Introduce <elf_machine_sym_no_match.h>
Implement __libc_early_init
nptl: Start new threads with all signals blocked [BZ #25098]
Mathieu Desnoyers (6):
Move elf/elf_machine_sym_no_match.h to sysdeps/generic
glibc: Perform rseq(2) registration at C startup and thread creation
(v17)
glibc: sched_getcpu(): use rseq cpu_id TLS on Linux (v7)
support record failure: allow use from constructor
support: implement xpthread key create/delete (v4)
rseq registration tests (v9)
