Hi,
Hauke here form OpenWrt, I am just reading this. ;-)
OpenWrt never shipped musl 1.1.20 or 1.1.23 in any final release.
OpenWrt 19.07 uses musl 1.1.24
OpenWrt 18.06 uses musl 1.1.19
I also checked that this is really using this version and not just
claims to do so.
I assume that some vendor forked a random OpenWrt master state and had a
problem with their broken application and "fixed" it by downgrading
musl, but they only changed the git commit hash which should be used
and not the version number.
I saw that lynxis just send this patch to use the official tar.gz for
musl and not check musl out from git any more, I assume this is related
to this discussion:
