Subject: [PATCH 0/1] rseq/selftests: add __rseq_abi misalignment check
Date: Mon, 6 Aug 2018 13:47:00 +0200 [thread overview]
Message-ID: <cover.thread-5c3a1c.your-ad-here.call-01533555685-ext-8699@work.hours> (raw)
While implementing rseq selftest for s390 a glibc problem with tls
variables alignment has been discovered. It turned out to be a general
problem affecting several architectures. The bug opened for this problem:
https://sourceware.org/bugzilla/show_bug.cgi?id=23403
There is no fix yet. On s390 __rseq_abi ends up aligned to 0x10 instead
of 0x20 which makes rseq selftest fail every time.
The change proposed adds __rseq_abi misalignment check, produces user
friendly message and skips the test.
