Subject: [PATCH v2] libselinux: be careful with non-portable LFS macro
Date: Sat, 26 Apr 2025 17:13:57 +0200

musl does not provide the obsolete LFS64 APIs (like ino64_t) — ino_t
has always been 64-bit on all platforms there. That means there's
also no __INO_T_MATCHES_INO64_T macro, meaning the check would pass
and reach the static asserts for the shim, which would fail due to
there being no ino64_t to check the size of. Fix this by only
assuming the absense of __INO_T_MATCHES_INO64_t is meaningful when
another non-portable Glibc macro, __INO64_T_TYPE, is defined. If both
are missing, that probably just means there is no ino64_t.
Fixes: 5c3fcbd9 ("Inject matchpathcon_filespec_add64() if !defined(__INO_T_MATCHES_INO64_T) instead of using __BITS_PER_LONG < 64 as proxy")

v2: Made the same change to the condition in the header, as suggested
in a GitHub comment. The omission didn't seem to break anything,
but it makes sense to change it there too.
