Subject: [RFC PATCH glibc 0/8] Restartable Sequences enablement
Date: Mon, 23 Mar 2020 09:15:59 -0400 [thread overview]
Message-ID: <20200323131607.15185-1-mathieu.desnoyers@efficios.com> (raw)
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:
- A copy of linux/rseq.h (reformatted to glibc's coding style) is
integrated into sys/rseq.h as a fallback when linux/rseq.h cannot be
found in the UAPI headers.
- This approach allows removing the __ASSUME_RSEQ macro.
- Introduce a _Static_assert in sys/rseq.h to validate that the compiler
meets the alignment requirements of the rseq UAPI, IOW that it does not
ignore the aligned attribute for struct rseq and struct rseq_cs.
- Document that posix_memalign should be used intead of malloc when
allocating struct rseq and struct rseq_cs on the heap.
Thanks for the feedback!
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 (5):
glibc: Perform rseq(2) registration at C startup and thread creation
(v16)
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)
