Do you observe the same message under GENERIC.MP kernel as well?

Synopsis: on XenServer 6.5 messages log is flooded with xen related events
Category: Xen
Environment:
System  : OpenBSD 5.9

Description:

On fresh installed system I noticed (in console first, then in messages) that 
log is flooded with records like:

xen0: grant table reference 802 is held by domain 0
xen0: grant table reference 924 is held by domain 0
xen0: grant table reference 1032 is held by domain 0

On this system I have enabled IP forwarding and NAT (with pf).

How-To-Repeat:

Install OpenBSD with 2 NICs, enable simple NAT rule, enable IP forwarding and 
activate PF, then pass some traffic through it.

match on $ext_if from $int_if:network to any nat-to ($ext_if)

Fix: Unknown

Mar 23 snapshot and ipv6 problem

2016-03-24 Thread Sebastien Marie
Hi,

I encountered a problem with IPv6 connectivity after upgrade to snapshot
Mar 23 on my amd64 router.

The router use a pppoe session to get IPv4 and IPv6. I had to made a
DHCP-ND request to get routable IPv6, and I use dhcpcd from ports for
that.

The IPv4 is ok, but for IPv6, dhcpcd has the following error:

Mar 24 20:16:33 alf dhcpcd[43667]: DUID 00:01:00:01:1e:40:7c:6c
Mar 24 20:16:33 alf dhcpcd[43667]: pppoe0: IAID 00:00:00:01
Mar 24 20:16:33 alf dhcpcd[43667]: pppoe0: IAID 00:00:00:02
Mar 24 20:16:33 alf dhcpcd[43667]: pppoe0: rebinding prior DHCPv6 lease
Mar 24 20:16:35 alf dhcpcd[43667]: pppoe0: dhcp6_sendmessage: sendmsg: Invalid 
argument
Mar 24 20:17:03 alf dhcpcd[43667]: timed out
Mar 24 20:17:03 alf dhcpcd[43667]: forked to background, child pid 10317


I had ktraced it for grabing the sendmsg syscall arguments used:

 43667 dhcpcd   CALL  sendmsg(10,0x1abbb5052020,0)
 43667 dhcpcd   STRU  struct msghdr { name=0x7f7c5260, namelen=28, 
iov=0x1abbb5052050, iovlen=1, control=0x1abbb5052070, controllen=40, flags=0 }
 43667 dhcpcd   STRU  struct iovec { base=0x1abb901b5000, len=167 }
 43667 dhcpcd   STRU  struct sockaddr { AF_INET6, [ff02::1:2]:547 }
 43667 dhcpcd   STRU  struct cmsghdr { len=36, level=41, type=46 }
 43667 dhcpcd   RET   sendmsg -1 errno 22 Invalid argument

Below a full dmesg.

Thanks.
