linux64 fails to load on 10.3-RELEASE


I'm on 10.3-RELEASE/amd64 and I'd like to use the new linux64 module.
However, when I do 'kldload linux64', I get:
kldload: an error occurred while loading the module. Please check
dmesg(8) for more details.

And I've got in dmesg(8):
link_elf_obj: symbol elf64_linux_shared_page_fini undefined
linker_load_file: Unsupported file type

I've got in my kernel:
options COMPAT_LINUX32

Can it interfere with linux64? If not, what else can I check?

OpenSSH changes between 10.2 and 10.3 ...

Hi, all,

minor problem/annoyance here:

root <at> noc:/etc/ssh # ssh admin <at>
Unable to negotiate with port 22: no matching key exchange method found. Their offer: diffie-hellman-group1-sha1,none
root <at> noc:/etc/ssh # uname -a
FreeBSD noc.pluspunkthosting.de 10.3-RELEASE FreeBSD 10.3-RELEASE #3: Wed Apr 13 14:46:57 CEST 2016    
root <at> noc.pluspunkthosting.de:/usr/obj/usr/src/sys/GENERIC  amd64

Of course I was able to find http://www.openssh.com/legacy.html myself.

FreeBSD 10.2 uses OpenSSH 6.6.x while 10.3 imported 7.2.
So far so good.

The recommended method from the document above works on the
command line:

	ssh -oKexAlgorithms=+diffie-hellman-group1-sha1 admin <at>

But if I add

	KexAlgorithms +diffie-hellman-group1-sha1

to /etc/ssh/ssh_config, that does not change anything. Oddly enough,
checking which algorithms are supported gives the same result
regardless of any configuration options:

root <at> noc:/etc/ssh # ssh -Q kex

VLAN problem on some em(4) cards

while replacing a switch I ran into a problem with using 802.1q VLANs
(vlan(4)) on a em(4) card - that is, I could not get the card to work
with VLANs.
Software is FreeBSD 10.3-RELEASE i386 with a custom kernel (but has
em(4) and vlan(4) compiled in (not as a module)).
Hardware is a Soekris net6501-70, the interface in question is (pciconf)
em2 <at> pci0:10:0:0:        class=0x020000 card=0x00008086 chip=0x10d38086 rev=0x00
    vendor     = 'Intel Corporation'
    device     = '82574L Gigabit Network Connection'
    class      = network
    subclass   = ethernet

The setup I wanted to create was a "router on a stick", that is having
3 (for starters) tagged VLANs on that one link between router and
switch. I was not able to get any packet through to the switch,
while tcpdump shows the packets on the vlan interface (but not on
the underlying em interface - I understand that this could be the
result of hardware vlan processing). I could not ping any host beyond
the switch nor the switch's management interface itself, I did not
even receive ARP replies.
I tried both manual creation of the vlan devices and the rc.conf/
netif mechanism - with the very same results ("doesn't work").
Experimenting with the vlanhw* flags on the em interface did not
result in any change.

To make sure it's not the switch (or my own mistake), I took another
host with an em interface - this time, it was a
em0 <at> pci0:0:25:0:        class=0x020000 card=0x21ce17aa chip=0x15028086 rev=0x04

FreeBSD and Intel XL710 Ethernet drivers and malicious driver detection

We have recently come across what appears to be a driver/firmware problem
with our Intel Ethernet Converged Network Adapter X710-DA2.  Wanted to see
if anyone had insight into whether it was a known bug and if any
fixes/workarounds exist.

Symptoms:  On two FreeBSD 10.2-STABLE r292570 amd64 instances with these
cards -- we experienced packet loss (incrementing packet error counts) at
exactly the same time we observed /var/log/messages such as those below.
Here are the details of our hardware/driver/firmware:


Intel Ethernet Card:
Dual Port, SFP 10GbE,
PCIe 3.0, x8

FreeBSD Drivers we are running:

# sysctl -a | grep dev.ixl.0.%desc
dev.ixl.0.%desc: Intel(R) Ethernet Connection XL710 Driver, Version - 1.4.3

Intel Firmware we were running:

# sysctl -a | grep dev.ixl.0.fw_version
dev.ixl.0.fw_version: f4.40 a1.4 n04.53 e80001dc0

IPFW with NAT : Problems with duplicate packets on FreeBSD 10.3-RC3

I’m scratching my head with an IPFW / NAT configuration; could someone please throw me a bone?

I’ve got a jail, and I’m NATing using IPFW to connect it to the outside world.

In particular I’m forwarding port 8080 from the host’s public address to the jail’s private address.

When I pull an HTTP connection from port publicip:8080 I get the first packet of the TCP stream twice, and
then the HTTP connection fails.
That ought not to happen :(.

The firewall rule is very simple

nat 1 config if vlan10 reset redirect_port tcp 8080 // NAT for jails - forward to portal on 8080
nat 1 ip from any to any via vlan10 in
nat 1 ip from any to any via vlan10 out

add allow ip from any to any

If I tcpdump on the host:

# tcpdump -i vlan10 port 8080
tcpdump: verbose output suppressed, use -v or -vv for full protocol decode
listening on vlan10, link-type EN10MB (Ethernet), capture size 65535 bytes

SSHd in FreeBSD 10.3 complains about PrintLastLog

I had "PrintLastLog yes" in my sshd_config for many years but after 
upgrade to 10.3 I got this error message:

/etc/ssh/sshd_config line 112: Unsupported option PrintLastLog

It is confusing because "#PrintLastLog yes" is still included in default 
sshd_config file and mentioned in manpage.

Is it error in default config or error in sshd? What should be fixed?
