glibc binding failure on kfreebsd

[sthibaul]

The debian package fails to build on kfreebsd*:

FAIL: glibc-sched
=================

glibc-sched: glibc-sched.c:43: main: Assertion `!err' failed.
Aborted (core dumped)
FAIL glibc-sched (exit status: 134)

See https://buildd.debian.org/status/fetch.php?pkg=hwloc&arch=kfreebsd-amd64&ver=1.11.13-1&stamp=1563986094&raw=0

(And the same happens with 2.1.0: https://buildd.debian.org/status/fetch.php?pkg=hwloc&arch=kfreebsd-amd64&ver=2.1.0%2Bdfsg-1&stamp=1571205479&raw=0 )

Is there a recent netinst iso for kfreebsd/gnu? Last time I tried installing it in our CI, there was only a Jessie but I couldn't install Jenkins on it (java too old, if I remember correctly).

As a Debian Developer, you can access the kfreebsd porter box, lemon.debian.net .

(I don't know if there are recent ISOs for kfreebsd)

I cannot get sched_set/getaffinity() to work, even when manually changing the size and contents of the bitmask, they always return EINVAL. I can't find any obvious bug in glibc/kfreebsd implementation. Don't know where to look now.

[sthibaul]

Ok, I guess we'll leave as it is for a BSD hacker to have a look at it.

Just for the record, with the move of checking for sched_setaffinity to the Linux-specific section, this test is not run any more. sched_setaffinity is actually glibc-specific (i.e. host_os ~= *gnu*) rather than Linux-specific, kFreeBSD/GNU does provide it, so its presence should rather be tested on all host_os ~= *gnu*. The current state should be fine enough though, until a kFreeBSD/GNU hacker looks at the matter.
