AIX capabilities not set
Hi,
we're in the process of setting up large-page support on IBM regattas,
but for large-page support the users have to have a set of extra
capabilities (CAP_BYPASS_RAC_VMM,CAP_PROPAGATE). This are configured
on a per user basis by listing which capability each user have in
/etc/security/user.
Unfortunately they don't get set when the users log in via OpenSSH
(3.1p1). Does anybody know

Are squeeze Xen dom0 kernels subject to this the same IPv6 GSO problem?
...nsfer. Doing the same data
transfer from the server dom0 itself does not show the same issue,
and the expected tens of MB/sec data transfer is achieved.
Here's an example tcpdump of when the problem is occurring:

[Bug 1343] New: With iPv6 masquerade, ICMPv6 time-exceeded pkts are forwarded with bad checksum
...the upstream interface just fine with good
cksum, but then on the forwarded-to interface (i.e. after translation) I get
bad checksum. The next hop does not see the packet at all.
I looked at nf_nat_proto_icmpv6.c for a bit but so far haven't found much.
Kernel 4.9.168.
e.g. on ingress:
IP6 (hlim 61, next-header ICMPv6 (58) payload length: 80) 2a01:4f9:0:c001::a015
> 2a01:???:????:????::1: [icmp6 sum ok] ICMP6, time exceeded in-transit for
fra16s12-in-x04.1e100.net
on egress:

syslinux.efi pxeboot across multiple subnets
The same client was used for syslinux.efi (both success on same subnet and
failure on different subnet) and grub.efi. The DHCP host block is setup
like:
host testing {
hardware ethernet {mac} ;
next-server 10.16.195.178 ;
filename "rhel64/syslinux.efi" ;
}
I'll pull a tcpdump filtering by the IP tomorrow when I get back to the
systems.
