Subject: alpha: force old OSF1 syscalls for getegid, geteuid and getppid [BZ #24986]
X-Git-Tag: changelog-ends-here~62
X-Git-Url: http://git.ipfire.org/?a=commitdiff_plain;h=1a6566094d3097f4a3037ab5555cddc6cb11c3a3;p=thirdparty%2Fglibc.git

alpha: force old OSF1 syscalls for getegid, geteuid and getppid [BZ #24986]

On alpha, Linux kernel 5.1 added the standard getegid, geteuid and
getppid syscalls (commit ecf7e0a4ad15287). Up to now alpha was using
the corresponding OSF1 syscalls through:
 - sysdeps/unix/alpha/getegid.S
 - sysdeps/unix/alpha/geteuid.S
 - sysdeps/unix/alpha/getppid.S

When building against kernel headers >= 5.1, the glibc now use the new
syscalls through sysdeps/unix/sysv/linux/syscalls.list. When it is then
used with an older kernel, the corresponding 3 functions fail.

A quick fix is to move the OSF1 wrappers under the
sysdeps/unix/sysv/linux/alpha directory so they override the standard
linux ones. A better fix would be to try the new syscalls and fallback
to the old OSF1 in case the new ones fail. This can be implemented in
a later commit.
