as you can see the list is truncated because the internal buffer isn't large enough, but I'm not sure it's the reason for the original error...

I manually tested cpuid feature check and it also says sse2 IS supported.

Steps To Reproduce
add a project Einstein@Home and enable Multi-Directional Gravitational Wave search on O3 (CPU)

Expected behavior
it doesn't accept work due to a missing feature sse2 which is supported on this CPU (no VMs or hacks are involved). Other boinc projects work just fine.

System Information

  • OS: Linux desktop-b49ep3v.easy.local 6.2.0-1275.native #1 SMP Wed Feb 22 18:59:06 PST 2023 x86_64 GNU/Linux
  • BOINC Version: 7.20.5

Additional context
see related code
https://github.com/BOINC/boinc/blob/master/lib/hostinfo.h#L53
https://github.com/BOINC/boinc/blob/master/client/hostinfo_unix.cpp#L530
https://github.com/BOINC/boinc/blob/master/client/hostinfo_unix.cpp#L683

and the original report https://einsteinathome.org/cs/content/ryzen-7950x-lacks-feature-sse2

let me know if there's more info / logs or tests I can provide. Thanks!

Message [version] CPU [' family 25 model 97 stepping 2 '] lacks feature ' sse2 ' is different from the message that could be sent from the vanilla code: https://github.com/BOINC/boinc/blob/master/sched/plan_class_spec.cpp#L278
That makes me think that E@H runs customized version of this utility, thus it can't be verified and/or fixed from our side

The vanilla code has a 1024-char buffer for CPU features, and I think it's being exceeded here.
I'll change it to std::string.

In the current version of the code (master branch), p_features size of the host record is still fixed 1024. That doesn't look right (and probably won't help):

    char p_features[1024];
