Description Dmitry V. Levin 2021-05-20 22:54:06 UTC

+++ This bug was initially created as a clone of Bug #1929836 +++

The scv ABI introduced by glibc-2.32.9000-24 at 2021-01-08 has the following bug: RET_SCV macro (added by upstream commit glibc-2.33~117) treats any negative value returned by syscall via scv ABI as an error, but this is not correct.

Proposed fix was posted by Nicholas Piggin at
https://sourceware.org/pipermail/libc-alpha/2021-May/126534.html

This bug was found by strace test suite and it blocks strace updates in Fedora.

I hope the fix will be applied before strace is kicked out from Fedora due to ftbfs which is 19 weeks already.
