net-libs/libnftnl-1.0.7::gentoo was built with the following: USE="examples json static-libs threads -test" Reproducible: Always
Created attachment 508758 [details] build.log
Same failure on ppc and ppc64.
Same on hppa, even for 1.0.8-r1.
Similar for ppc and ppc64. Looks like full Big Endian house.
Found endianness problem (manifests in json parser): https://git.netfilter.org/libnftnl/tree/src/utils.c#n82 int nftnl_get_value(enum nftnl_type type, void *val, void *out) { int64_t sval; uint64_t uval; switch (type) { case NFTNL_TYPE_U8: case NFTNL_TYPE_U16: case NFTNL_TYPE_U32: case NFTNL_TYPE_U64: uval = *((uint64_t *)val); if (uval > basetype[type].max) { errno = ERANGE; return -1; } memcpy(out, &uval, basetype[type].len); break; As a result 'out' does not contain any data if, say 'type' is NFTNL_TYPE_U32: - memcpy copies first four bytes - actual value is in last 4 bytes (big-endian leyout)
And the cast before is probably also wrong. The value is casted to an uint64_t*, so the compiler can assume it has the proper alignment, and optimize the following memcopy away. It's in fact not needed at all if it is only passed to memcpy, this is fine with void*.
This looks like it could be the fix: https://git.netfilter.org/libnftnl/commit/src/utils.c?id=9737856067b97cbb869e04fc6b6e65c1d859f521
