The ebuild fails for me as well (with only -fno-semantic-interposition and without LTO), but I found that the vanilla package works just fine *with* it. Apparently the iproute2-5.12.0-configure-nomagic patch is to blame since it now somehow breaks the built-in check for strlcpy. When I delete the NEED_STRLCPY section in lib/utils.c it also works, so this is not a problem in glibc.
While the problems building with USE=-libbsd are self-inflicted by the aforementioned patch, the good news here is that they can be circumvented for now by USE=libbsd, which will trick the iproute2 config process into ignoring both glibc's strlcpy and the provided version, using libbsd as intended. It will then build fine. IMHO the sanest way forward here is to remove libbsd as USE flag and either use it or not, depending on glibc >= 2.38.
This happens here too. >/usr/include/bits/string_fortified.h: In function 'strlcat': >/usr/include/bits/string_fortified.h:150:1: error: inlining failed in call to 'always_inline'

Please use attachments for large pastes. Please also avoid making bug reports with -ffast-math, as it breaks standards compliance and is not simply an optimisation. -fipa-pta should also not be used unless you measure a performance improvement, per GCC upstream recommendations, because it's both a buggy optimisation pass for now but also very slow at compile-time. Anyway, your second paste is unrelated.

This happens even with COMMON_FLAGS="-O1 -fno-semantic-interposition" or higher -O level. However, it works with COMMON_FLAGS="-O0 -fno-semantic-interposition" or COMMON_FLAGS="-fno-semantic-interposition"

(In reply to stefan11111 from comment #6) > -fipa-pta is one of the recommendations from the GentooLTO overlay. I don't think there's much that the LTO overlay actually recommends, they recognize that it's experimental and it's just something that's attempted by default until someone reports an issue so they can disable it by default for specific packages. Albeit IMO that one should just be dropped entirely.

After looking a bit further into this it seems the opposite is true, and we should just remove any dependency on libbsd, since that is just not needed at all moving forward due to the existing strlcat/strlcpy implementations in iproute. Upstream's "optional fallback" to libbsd was really the worst possible idea here.
WIP branch, iproute2-6.4.0 only for now: https://github.com/hhoffstaette/gentoo/commits/iproute2 This: - removes the libbsd USE and dependency, which is not needed - undoes the libbsd enforcement by iproute2-5.12.0-configure-nomagic.patch - removes the optional libbsd fallback from iproute's configure All this will make iproute2 use glibc's strlcpy when built on glibc-2.38. It builds successfully & works with LTO and -fno-semantic-interposition. Would appreciate if someone could test the build on glibc <2.38, where it should simply fall back onto its own strlcpy. If it works I'll make a PR.
(In reply to Holger Hoffstätte from comment #10) Thanks for the investigation!
Created attachment 869880 [details] iproute2 build.log without libbsd
Built successfully with glibc 2.37-r3.

It is also no longer needed since glibc-2.38; for older glibc versions we can let configure fall back to iproute's built-in strlcpy.
