In case somebody hits this, here's a resolved issue: -fno-wrapv is
matters for UBSan coverage.
Confusion starts with:
$ uname -srm; cat a.c && clang -fsanitize=undefined a.c -c -o a.o && nm a.o
OpenBSD 7.0 amd64
int main(int argc, char **argv) {
int k = 0x7fff;
k += argc;
return 0;
}
00
This change is OK with me.
The mdns.allow stuff should be fixed by go recognizing that it doesn't
exist in OpenBSD, and not attempting the open.

A go program that uses pledge("dns") mostly works except for two
incompatibilities with the way golang's dns library works. Otherwise
pledge("rpath") is required.
1. go likes to stat /etc/hosts to check for changes. I think this is
reasonable behavior. Patch below adds a whitelist to the kernel to

My confusion is easily resolved. People use UBSan in the kernel w
To add a bit more color, the same problem happens with ports clang from

Sure, added one.

Ok. Updated
In tr(1), we have these two global arrays, "string1" and "string2".
I have a few complaints:
1. They are not strings. They are lookup tables. The names are

2. The arguments given to tr(1) in argv[] are indeed called "string1"
and "string2". These are the names used in the st
