Description Sam James archtester Gentoo Infrastructure gentoo-dev Security 2023-03-30 22:38:07 UTC
musl-1.2.4 (9999 right now) will remove/removes the LFS compatibility hacks, like fopen64:
- https://git.musl-libc.org/cgit/musl/commit/?id=246f1c811448f37a44b41cd8df8d0ef9736d95f4
- https://git.musl-libc.org/cgit/musl/commit/?id=25e6fee27f4a293728dd15b659170e7b9c7db9bc

The gist is that bad configure tests (suffering from -Wimplicit-function-declaration) would build and link successfully because musl provided these symbols as aliases, despite not needing them (musl natively supports both LFS & time64).

To head this off, these aliases are now gone, but remain in libc.so for binary compatibility.

The fix is to just use the regular functions and not anything _LARGEFILE64_SOURCE.

As a workaround, we can pass -D_LARGEFILE64_SOURCE in tricky cases *for one release cycle*. musl will drop that compatibility hack entirely in the next release *after* 1.2.4.
