Hello together,
I have set up a PC using jhalfs with SVN-20200201. This is not the
first
time installing LFS for me.
glibc-2.31, I think ?
I saw something about openssh and that yesterday, somewhere. Ah
yes, at the bottom of https://lwn.net/Articles/811275/#Comments
(that might be subscribers only at the moment so I'll quote) - "it
might be useful to know that the current OpenSSH (8.1p1) needs some
patches backported to update the system call filter - grab the last
few from here. Without those, it'll just close the connection when
you try to log in, as nanosleep causes a SIGSYS. Otherwise it all
seems to work well so far!"
And 'here' is a link to
https://github.com/openssh/openssh-portable/commits/master/sandbox-seccomp-filter.c
I'm not sure, but I'll guess perhaps latest back as far as Nov 13th,
or maybe not all of those. Unfortunately, I'm not running
glibc-2.31 at the moment (looking for pre-existing problems, so I
can distinguish them from glibc-related).
If you patch it successfully, please let us know and provide the
patch. Thanks.

We had folksingers in the lower bar for six months back home where
I worked. In the end we had to get a man in with a ferret.

The following single patch fixed the issue for me:
https://src.fedoraproject.org/rpms/openssh/raw/master/f/openssh-8.1p1-seccomp-nanosleep.patch
Thanks Wayne. Taking a look at the patch, the second part appears to
only apply to ARM. When I look at the source for openssh-8.0p1, the
first part seems to be present already.
Are we talking about an ARM installation here?
Never mind. The patch seemd to do the right thing.
