[PATCH iproute2] ip: Support IFLA_TXQLEN in ip link show command
We currently use an expensive ioctl() to get device txqueuelen, while
rtnetlink gave it to us for free. This patch speeds up ip link operation
when many devices are registered.

The genl code uses constructs which violate the strict aliasing
constraints of gcc 4.4. Disable the optimization to avoid warnings
and potential breakage.
User can specify device group to list by using the group keyword:
ip link show group test
If no group is specified, 0 (default) is implied.

Hi,
here is a patch against iproute2 to allow user to set a state with a specific
auth length.
Example:
$ ip xfrm state add src 10.16.0.72 dst 10.16.0.121 proto ah spi 0x10000000
auth-trunc "sha256" "azertyuiopqsdfghjklmwxcvbn123456" 96 mode tunnel
$ ip xfrm state
src 10.16.0.72 dst 10.16.0.121
proto ah spi 0x10000000 reqid 0 mode tunnel
replay-window 0
auth-trunc hmac(sha256)

Subject: [PATCH] iproute2: allow to specify truncation bits on auth algo
Attribute XFRMA_ALG_AUTH_TRUNC can be used to specify
truncation bits, so we add a new algo type: auth-trunc.

The get_jiffies() function retrieves rtt-type values in units of
milliseconds. This patch updates the function name accordingly,
following the pattern given by dst_metric() <=> dst_metric_rtt().
Since July 2008 (2.6.27, c1e20f7c8b9), the kernel stores the values for
RTAX_{RTT{,VAR},RTO_MIN} in milliseconds. When using a kernel > 2.6.27 with
the current iproute2, conversion of these values is broken in either way.
This patch
* updates the code to pass and retrieve milliseconds;
* since values < 1msec would be rounded up, also drops the usec/nsec variants;
* since there is no way to query kernel HZ, also drops the jiffies variant.
Arguments such as
rtt 3.23sec
rto_min 0xff
rto_min 0.200s
rttvar 25ms
now all work as expected when reading back previously set values.
In the Linux kernel, ipsec policy and SAs can include a
security context to support MAC networking. This feature
is often referred to as "labeled ipsec".
This patchset adds security context support into ip xfrm
such that a security context can be included when
add/delete/display SAs and policies with the ip command.
The user provides the security context when adding
SAs and policies. If a policy or SA contains a security
context, the changes allow the security context to be displayed.
For example,
ip xfrm state
src 10.1.1.6 dst 10.1.1.2
proto esp spi 0x00000301 reqid 0 mode transport
replay-window 0
auth hmac(digest_null) 0x3078
enc cbc(des3_ede) 0x6970763672656164796c6f676f33646573636263696e3031
security context root:system_r:unconfined_t:s0
Please let me know if all is ok with the patchset.
Thanks!!

Add support for 'passthru' mode when creating a macvlan/macvtap device
which allows takeover of the underlying device and passing it to a KVM
guest using virtio with macvtap backend.
Only one macvlan device is allowed in passthru mode and it inherits
the mac address from the underlying device and sets it in promiscuous
mode to receive and forward all the packets.

While the previous code was supposed to work nonetheless, it could be
messed up if further -L were used in LDFLAGS to list the path where glibc's
libutil was to be found.

Add the group keyword to ip link set, which has the following meaning:
If both a group and a device name are pressent, we change the device's
group to the specified one. If only a group is present, then the
operation specified by the rest of the command should apply on an entire
group, not a single device.
So, to set eth0 to the default group, one would use
ip link set dev eth0 group default
Conversely, to set all the devices in the default group down, use
ip link set group default down
