New loader (installed with ALPHA3) complains about missing modules but doesn't say what it needed

2018-08-31 Thread Lev Serebryakov
Hello FreeBSD,

   When I rebuilt NanoBSD image from CYRRENT r336582 to ALPHA3 r338399
 loader starts to complain that it could not find required module(s). But I
 don't have any in my /boot/loader.conf and I didn't change anything in my
 configs.

  Unfortunately, loader doesn't provide any details: which modules are
 required.

Regression: ALPHA3 can not properly init diskless / nanobsd system

2018-08-31 Thread Lev Serebryakov
Hello FreeBSD,

 I have NanoBSD system built from and it works. It creates THREE memory
filesystems, as needed:

% mount | grep /dev/md
/dev/md0 on /etc (ufs, local)
/dev/md1 on /var (ufs, local)
/dev/md2 on /var/tmp (ufs, local)
%

 But same system built from ALPHA3 sources (r338399 to be exact) doesn't
create /etc in-memory overlay, and can not copy SSHD keys and create
host.conf. After that sshd could not start.

 New version doesn't properly create overlay for /etc:

% mount | grep /dev/md
/dev/md1 on /var (ufs, local)
/dev/md2 on /var/tmp (ufs, local)
%

 All configuration files are the same.

I tried the patches from D16972 and it seems to work on a DELL Latitude
E6520. It now boots with OPTIONS EFIRT and without efi.rt.disabled=1.

Many thanks!

A version of the patch which finishes items which I wanted
to handle, is available both for review and for testing at
https://reviews.freebsd.org/D16972 .

Re: NFS via IPv6 between 11.2-REL amd64 and larger (>45 files) directories?

2018-08-31 Thread Kurt Jaeger
Hi!

As Rick told me there's a ongoing debate on this, here's a copy
from my mail to stable@:

I've seen a strange effect: NFS via IPv6 between 11.2-REL amd64
boxes failed for directories with more than 45 files or directories.
Small directories worked. It seems to be an issue with
ipv6 fragmentation (?), as can be seen by tcpdump:

17:54:16.855978 IP6 nfs-serv > nfs-client frag (0|1448) 2049 > 709: NFS reply 
xid 1536109002 reply ok 1440 readdir
17:54:16.855979 IP6 nfs-serv > nfs-client frag (1448|36)

As soon as the NFS request is sent with fragments, it stalls.

Using TCP or IPv4 for the nfs mount works, UDP fails.
