https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=3D225922 Bug ID: 225922 Summary: security/libargon2: optimised code gives illegal instruction fault on older/less capable machines Product: Ports & Packages Version: Latest Hardware: amd64 OS: Any Status: New Severity: Affects Only Me Priority: --- Component: Individual Port(s) Assignee: freebsd-ports-bugs@FreeBSD.org Reporter: arthur@qeng-ho.org CC: hsw@bitmark.com CC: hsw@bitmark.com Flags: maintainer-feedback?(hsw@bitmark.com) The Gnu makefile for argon2 by default compiles for the build machine architecture. Unfortunately I use poudriere to build a local package reposi= tory on my fastest machine and install packages on all other machines on my netw= ork. My build machine has AVX-512 instructions, the machine I want to run the co= de on doesn't and crashes with an illegal instruction when it hits a vxorps opcode. The ports Makefile has no option to control whether or not optimised code is used, that depends only on the actual hardware used for the build. It needs= an option to disable use of the optimised code. I've got a quick hack to the Makefile that works, but don't know if it's of suitable quality for ports. = The diff is attached. I reused the standard SIMD option as the control. --=20 You are receiving this mail because: You are the assignee for the bug.=
