Subject: [PATCH][pseudo 7/7] ports/linux/xattr: add arm64 versions for xattr calls
Date: Fri, 8 Jan 2021 14:06:40 +0000 [thread overview]
Message-ID: <20210108140640.1069133-7-ross.burton@arm.com> (raw)
In-Reply-To: <20210108140640.1069133-1-ross.burton@arm.com>
The xattr functions need to use a specific version of the symbols to avoid
calling into libattr.so, which on Tumbleweed causes failures[1].
However on arm64 systems the glibc version is different. This means that
searching for llistattr(GLIBC_2.3) fails to initially match the symbol in
libc.so, and instead if libattr.so is linked then the symbol in that library
is used. This is simply a wrapper that is intended to call the symbol in
libc.so but instead calls the symbol in pseudo, so infinite loops.
Using the just-added architecture overrides, add the right versions for
arm64 systems so the correct symbols in libc.so are found.
