What's weird is that other verify-sig packages (outside of LLVM, I guess) are fine: ``` >>> Emerging (1 of 1) sys-apps/sed-4.8::gentoo * sed-4.8.tar.xz BLAKE2B SHA512 size ;-) ...

Works okay outside of Portage: ``` # gemato gpg-wrap -K /usr/share/openpgp-keys/llvm.asc -R -- gpg --verify /var/tmp/portage.notmp/portage/sys-libs/compiler-rt-sanitizers-14.0.6/distdir/llvm-project-14.0.6.src.tar.xz.sig /var/tmp/portage.notmp/portage/sys-libs/compiler-rt-sanitizers-14.0.6/distdir/llvm-project-14.0.6.src.tar.xz gpg: Signature made Sat Jun 25 05:09:12 2022 BST gpg: using RSA key 474E22316ABF4785A88C6E8EA2C794A986419D8A gpg: Good signature from "Tom Stellard <tstellar@redhat.com>" [ultimate] ``` And as non-root. Apparently it can't handle the dir being "/var/tmp/portage.notmp". Maybe permissions or something (although they seem right to me). Maybe it exceeds UNIX socket path limit. Try setting a shorter TMPDIR inside the verify-sig eclass. If that helps, I can update it to use a shorter TMPDIR for gpg invocations.

If that helps, I can update it to use a > shorter TMPDIR for gpg invocations. That seems to be it. The long package name 'compiler-rt-sanitizers' seems to push it over the limit. The other LLVM packages, with shorter names but using the same eclass, work fine. The following was working for me at the command prompt but not during the build: gemato gpg-wrap -K /usr/share/openpgp-keys/llvm.asc -R -- gpg --verify /mnt/scratch/portage/portage/sys-libs/compiler-rt-sanitizers-14.0.6/distdir/llvm-project-14.0.6.src.tar.xz.sig /mnt/scratch/portage/portage/sys-libs/compiler-rt-sanitizers-14.0.6/distdir/llvm-project-14.0.6.src.tar.xz I altered TMPDIR to be /mnt/scratch instead of /mnt/scratch/portage (it seems it creates its own portage subdirectory anyway) and the build worked. I don't know whether it's worth using a shortened name in the compiler-rt-sanitizers ebuild or perhaps adding a length check in the llvm.org eclass. Just using a shortened name should reduce the likelihood of hitting this. As you can see, shaving off just eight characters worked for me.
