Enable support for configuring outer UDP checksums on Geneve tunnels:
ip link add type geneve id 10 remote 10.0.0.2 udpcsum
Signed-off-by: Jesse Gross <jesse@kernel.org>
On recent kernels, UDP checksum computation has become more efficient and
the default behavior was changed, however, the ip command overrides this
by always specifying a particular behavior.
If the user does not specify that UDP checksums should either be computed
or not then we don't need to send an explicit netlink message - the kernel
can just use its default behavior.

Older kernels use -1 internally as indicator to use the sysctl default,
but they still export the setting. Newer kernels use 0 to indicate that
(which is why the conversion from -1 to 0 was done here), but they also
stopped exporting the value. Since the meaning of -1 is clear, treat it
equally like default on newer kernels (which is to not print anything).

Technically, the range of possible hoplimit values are defined by IPv4
and IPv6 header formats. Both define the field to be eight bits in size,
which leads to a value range of [0;255]. Setting a packet's hoplimit
field to 0 though makes not much sense, as the next hop would
immediately drop the packet. Therefore Linux uses 0 as a special value
indicating to use the system's default hoplimit (configurable via
sysctl). In iproute, setting the hoplimit of a route to 0 is equivalent
to omitting the hoplimit parameter alltogether, so it is actually not
necessary to allow that value to be specified, but keep it anyway for
backwards compatibility.

I found recently that, if I disabled address promotion in the kernel, that
ip addr flush dev <dev>
would fail with an EADDRNOTAVAIL errno (though the flush operation would in fact
flush all addresses from an interface properly)
Whats happening is that, if I add a primary and multiple secondary addresses to
an interface, the flush operation first ennumerates them all with a GETADDR |
DUMP operation, then sends a delete request for each address. But the kernel,
having promotion disabled, deletes all secondary addresses when the primary is
removed. That means, that several delete requests may still be pending in the
netlink request for addresses that have been removed on our behalf, resulting in
EADDRNOTAVAIL return codes.
It seems the simplest thing to do is to understand that EADDRUNAVAIL isn't a
fatal outcome on a flush operation, as it just indicates that an address which
you want to remove is already removed, so it can safely be ignored.

Currently 'ip route get' does not show the table the lookup result comes
from and prior to kernel commit c36ba6603a11 the response from the kernel
was hardcoded to the main table. From the discussion this appears to be
a leftover from the route cache where the cached entry lost the table id
and so the result was hardcoded to main table.
c36ba6603a11 added the RTM_F_LOOKUP_TABLE flag to maintain that behavior
but to allow new tools to ask for the actual table id for the lookup.
This patch adds that flag to ip route get request and if the result is
not the main table shows the table id.

Currently when we specify AF_INET6 when it is disabled, we will get
all routes.
For example, we can boot kernel with ipv6.disable=1 and try to get ipv6
routes:
$ ip -6 route show
default via 192.168.122.1 dev eth0 proto static metric 100
192.168.122.0/24 dev eth0 proto kernel scope link src 192.168.122.141 metric 100

by forcing whatever follows 'dev' to be presumed as interface name.

If a tunnel is created with a local address, you can't change it to any.
# ip tunnel add tunl1 mode ipip remote 10.16.42.37 local 10.16.42.214 ttl 64
# ip tunnel show tunl1
tunl1: ip/ip remote 10.16.42.37 local 10.16.42.214 ttl 64
# ip tunnel change tunl1 local any
# echo $?
0
# ip tunnel show tunl1
tunl1: ip/ip remote 10.16.42.37 local 10.16.42.214 ttl 64
It happens that parse_args zeroes ip_tunnel_parm, and when creating the
tunnel, it is OK to leave it as is if the address is any. However, when
changing the tunnel, the current parameters will be read from
ip_tunnel_parm, and local and remote address won't be zeroes anymore, so
it needs to be explicitly set to any.

The kernel now has the capability to offload FDB and FIB entries to hardware.
It is important to let users know if table entries are also offloaded to
hardware. Currently offloaded FDB entries are indicated by the existence of
the flag 'external' on the entry as of the following commit:
commit 28467b7f3f
Author: Scott Feldman <sfeldma@gmail.com>
Date: Thu Dec 4 09:57:15 2014 +0100
bridge/fdb: add flag/indication for FDB entry synced from offload device
When the patch to add support for indicating that FIB entries were also
offloaded as posted to netdev by Scott Feldman it became clear that 'external'
would not be an ideal name for routes. There could definitely be confusion
about what this might mean since many routes are to external networks -- a
collision/confusion that did not happen with FDB.
Scott Feldman asked me to check with others and build concensus around a name.
After speaking with several people about this I am proposing we refer to both
FDB and FIB entries that are currently backed by hardware (based on the work
done in rocker) with the flag 'offload' appended to the end ofthe entry.
Some people liked the string 'external,' others liked 'hardware,' but the point
is to communicate that these routes are available to something that will will
offload the forwarding normally done by the kernel. Since the term 'offload'
is used so frequently it seems appropriate to use the same language in
ip/bridge output.
The term 'offload' also seems to resonate with many of the people who have
responded on Scott's original thread or to those who I reached out to directly
and did respond to my query, so it seems we have reached consensus that it
should be the term used going forward.

as is done with AF_DECnet
The address syntax for multiple mpls labels is a complete invention.
When I looked there seemed to be no wide spread convention for talking
about an mpls label stack in text for. Sometimes people did:
"{ Label1, Label2, Label3 }", sometimes people would do:
"[ label3, label2, label1 ]", and most of the time label
stacks were not explicitly shown at all.
The syntax I wound up using, so it would not have spaces and so it
would visually distinct from other kinds of addresses is.
label1/label2/label3 Where label1 is the label at the top of the label
stack and label3 is the label at the bottom on the label stack.
When there is a single label this matches what seems to be convention
with other tools. Just print out the numeric value of the mpls label.
The netlink protocol for labels uses the on the wire format for a
label stack. The ttl and traffic class are expected to be 0. Using
the on the wire format is common and what happens with other address
types. BGP when passing label stacks also uses this technique with the
exception that the ttl byte is not included making each label in a BGP
label stack 3 bytes instead of 4.

This attribute is like RTA_DST except it specifies the destination
address to place on a packet when it leaves the host. For ip based
protocols this is destination NAT and not a common part of forwarding.
For protocols like MPLS label swapping is something that typically
happens on every hop.
There is likely to be a RTA_NEWSRC at some point so RTA_NEWDST
is printed as "as to" and can be specified either as "as to"
or just "as"

Joining multicast group on ethernet level via "ip maddr" command would
not work if we have an Ethernet switch that does igmp snooping since
the switch would not replicate multicast packets on ports that did not
have IGMP reports for the multicast addresses.
Linux vxlan interfaces created via "ip link add vxlan" have the group option
that enables then to do the required join.
By extending ip address command with option "autojoin" we can get similar
functionality for openvswitch vxlan interfaces as well as other tunneling
mechanisms that need to receive multicast traffic.
example:
ip address add 224.1.1.10/24 dev eth5 autojoin
ip address del 224.1.1.10/24 dev eth5

This patch adds support to remote checksum checksum offload
confinguration for IPIP, SIT, and GRE tunnels. This patch
adds a [no]encap-remcsum to ip link command which applicable
when configured tunnels that use GUE.
http://tools.ietf.org/html/draft-herbert-remotecsumoffload-00
Example:
ip link add name tun1 type gre remote 192.168.1.1 local 192.168.1.2 \
ttl 225 encap fou encap-sport auto encap-dport 7777 encap-csum \
encap-remcsum
This would create an GRE tunnel in GUE encapsulation where the source
port is automatically selected (based on hash of inner packet),
checksums in the encapsulating UDP header are enabled (needed.for
remote checksum offload), and remote checksum ffload is configured to
be used on the tunnel (affects TX side).

This patch makes CAN_CTRLMODE_FD_NON_ISO netlink feature configurable.
During the CAN FD standardization process within the ISO it turned out that
the failure detection capability has to be improved.
The CAN in Automation organization (CiA) defined the already implemented CAN
FD controllers as 'non-ISO' and the upcoming improved CAN FD controllers as
'ISO' compliant. See at http://www.can-cia.com/index.php?id=1937
Starting with the - currently non-ISO - driver for M_CAN v3.0.1 introduced in
Linux 3.18 this bit needs to be propagated to userspace. In future drivers this
bit will become configurable depending on the CAN FD controllers capabilities.

As 'ip monitor' by default subscribes to the all mcast rtnl groups except

* IFLA_VF_TX_RATE: When IFLA_VF_TX_RATE is used, min_tx_rate is always read
in kernel space. This takes care of below scenarios:
(1) when old tool sends "rate" but kernel is new (expects min and max)
(2) when new tool sends only "rate" but kernel is old (expects only "rate")
o Change in v4 as suggested by Stephen Hemminger:

When configuring a system with multiple network uplinks and default routes, it
is often convenient to reference a routing table multiple times - but reject
its routing decision if certain constraints are not met by it.
Consider this setup:
$ ip route add table secuplink default via 10.42.23.1
$ ip rule add pref 100 table main suppress_prefixlength 0
$ ip rule add pref 150 fwmark 0xA table secuplink
With this setup, packets marked 0xA will be processed by the additional routing
table "secuplink", but only if no suitable route in the main routing table can
be found. By suppressing entries with a prefixlength of 0 (or less), the
default route (/0) of the table "main" is hidden to packets processed by rule
100; packets traveling to destinations via more specific routes are processed
as usual.
It is also possible to suppress a routing entry if a device belonging to
a specific interface group is to be used:
$ ip rule add pref 150 table main suppress_group 1

The netns code was using EXIT_SUCCESS/EXIT_FAILURE but the rest of the ip
code used -1 explictly, so change to follow convention. Also, certain types
of errors like fork failure should abort a batch operation, rather than just
returning an error.
execvp() does not return when the command succeed, hence all commands in the
batch file after the line 'ip netns exec' are not executed.
Let's fork before calling execvp() if batch mode is used..
Example:
$ cat test.batch
netns add netns1
netns exec netns1 ip l
netns
$ ip -b test.batch

link/sit 0.0.0.0 brd 0.0.0.0
All command after 'netns exec' are never executed.

When unmanaged L2TP sessions are created using "ip l2tp add session",
there is no option to allow the session's Layer2SpecificHeader type to
be selected - the kernel's default setting is always used. For
interopability with some vendor equipment, it might be necessary to
use a different setting. So add a new l2spec_type parameter to the "ip
l2tp add session" parameter list, allowing operators to set a specific
Layer2SpecificHeader type. The kernel already exposes the setting as a
netlink attribute so it is straightforward to add support for it in
iproute2.

Fixes Debian bug #700434
Need to table id in filter to be unsigned to avoid conversion to -1
The documentation for "ip" suggests that, when using multiple routing tables, the table ID can be an arbitrary 32 bit number. I've been writing a script that calculates a table Id based on an IP addresses and sets up tables accordingly based on it. This seems to work for everything I've tried except "ip route flush". If you specify a table to flush with an ID over 2^31, it flushes all IPv4 routing tables. For example:
Will delete all routing tables, including the default one. Needless to say, this is quite annoying. I think this is an upstream bug, but your opinions will be greatly appreciated.

Sometimes "ip netns delete" fails because it can not delete the file a
network namespace was mounted on. If this only happened when a
network namespace was really in use this would be fine, but today it
is possible to pin all network namespaces by simply having a long
running process started with "ip netns exec".
Every mount is copied when a network namespace is created so it is
impossible to prevent the mounts from getting into other mount
namespaces. Modify all mounts in the files and subdirectories of
/var/run/netns to be shared mount points so that unmount events can
propogate, making it unlikely that "ip netns delete" will fail because
a directory is mounted in another mount namespace.

Some time ago the save+restore commands were added to ip route (git
id f4ff11e3, Add ip route save/restore). These two save the raw rtnl
stream into a file and restore one (reading it from stdin).
The problem is that there's no way to get the contents of the dump
file in a human readable form. The proposal is to add a command that
reads the rtnl stream from stdin and prints the data in a way the
usual "ip route list" does?
changes since v1:
* Take the magic at the beginning of the dump file into account
* Check for stdin (the dump is taken from) is not a tty

Hi,
I've attached a trivial patch for iproute2 to allow naming interfaces
created with "ip l2tp add session".
I believe patches should go through the netdev mailing list but this
patch is so small I figured that would just add noise. Hope that's OK.
Originally I thought I would need a bigger patch and was going to take a
stab at implementing something like
ip l2tp add tunnel L2TP_TUNNEL_ARGS
ip link add name NAME [ LINK_OPTS ] type l2tp L2TP_SESSION_ARGS
(a better interface IMHO) but all the code was there already, all that I
needed to add was option parsing.
Thanks,

Subject: [PATCH] ipl2tp: allow setting session interface name
The kernel supports a link mode attribute (which can be dormant or default).
This attribute is used to control how the link watch engine
handles operstate transistion.
This adds a new parameter to ip link command to allow setting and
displaying the value.
---
There is nothing in the standard that says 0 can't be used as a key.
It makes sense to allow it. Also fix typo where ikey was printed for
when printing okey.
Change the order of evaluation of ip link type arguements to allow
changing parameters of gre tunnels.
The following wouldn't work:
# ip li add mytunnel type gretap remote 1.1.1.1 key 3
# ip li set mytunnel type gretap key 9
LIBNETLINK will be defined in the main Makefile, so
both ../lib/libnetlink.a ../lib/libutil.a will be
automatically appended during linking. Otherwise
../lib/libnetlink.a ../lib/libutil.a will appear
twice during linking.

Alternative fix to problem reported by: Bin Li
The issue is came from https://bugzilla.novell.com/show_bug.cgi?id=681952.
In any previous version (since suse ... 10.0?), ip addr add always returned
the error code 2 in case the ip address is already set on the interface:
inet 172.16.2.3/24 brd 172.16.2.255 scope global bond0
RTNETLINK answers: File exists
2
On 11.4, it returns the exit code 254:
inet 172.16.1.1/24 brd 172.16.1.255 scope global eth0
RTNETLINK answers: File exists
254
This of course causes ifup to return an error in this quite common case..
When changing ip6ip6 parameters (ip -6 tun change), ip passes zeroed
struct ip6_tnl_parm to the kernel. The kernel then tries to change all of
the tunnel parameters to the passed values, including zeroing of local and
remote address. This fails (-EEXIST in net/ipv6/ip6_tunnel.c:ip6_tnl_ioctl).
For other tunnel types, ip fetches the current parameters first and applies
the required changes on top of them. This patch applies the same code as in
ip/iptunnel.c to ip/ip6tunnel.c.

The goal of this code change is to implement a mechanism such that it is
simple to work with a kernel that is using multiple network namespaces
at once.
This comes in handy for interacting with vpns where there may be rfc1918
address overlaps, and different policies default routes, name servers
and the like.
Configuration specific to a network namespace that would ordinarily be
stored under /etc/ is stored under /etc/netns/<name>. For example if
the dns server configuration is different for your vpn you would create
a file /etc/netns/myvpn/resolv.conf.
File descriptors that can be used to manipulate a network namespace can
be created by opening /var/run/netns/<NAME>.
This adds the following commands to iproute.
ip netns add NAME
ip netns delete NAME
ip netns monitor
ip netns list
ip netns exec NAME cmd ....
ip link set DEV netns NAME
ip netns exec exists to cater the vast majority of programs that only
know how to operate in a single network namespace. ip netns exec
changes the default network namespace, creates a new mount namespace,
remounts /sys and bind mounts netns specific configuration files to
their standard locations.

There are no functional changes made.
The documentation for the ip command has many different meanings for the

consistent use of brackets [ ] to indicate optional parameters, pipes | to
mean "OR", braces { } to group things together, and dashes - instead of
underscores _ inside of parameter names. The parameters are listed in the
order in which they are parsed in the source code.
There are several parameters and options that are still not mentioned or

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.

The user provides the security context when adding
SAs and policies. If a policy or SA contains a security

For example,

This patch adds save and restore commands to "ip route". Save dumps
the RTNL stream to stdout which can then be passed to restore later.
This may be helpful in some normal situations, and will allow C/R to
migrate the routing information in userspace. Tweaking of the stream
can be done by userspace helpers to convert between versions and adjust
things like device indexes when restoring routes in a different
environment.
By factoring out some of the common bits of print_route() into
filter_nlmsg(), the "save" command can use the same selection logic
as "list," allowing the caller to save only specific routes as
necessary.
The only change since the RFC is the addition of manpage and doc
material.

The old 'ip addr flush' logic had several flaws:
* It reversed logic for primary v/s secondary flags
(though, it sort of worked right anyway)
* The code tried to remove secondaries and then primaries,
but in practice, it always removed one primary per loop,
which not at all efficient.
* The filter logic in the core would run only the first
filter in most cases.
* If you used '-s -s', the ifa_flags member would be
modified, which could make future filters fail
to function fine.
This patch attempts to fix all of these issues.

This patch provides iproute2 facilities to configure 6rd tunnel. To
configure a 6rd tunnel, you need to configure a sit tunnel and set

ip tunnel add sit1 mode sit local a.b.c.d ttl 64
ip tunnel 6rd dev sit1 6rd-prefix xxxx:yyyy::/z
Optionally you can provide a relay prefix :

Finally you can reset previous tunnel settings :
ip tunnel 6rd dev sit1 6rd-reset

Currently you can configure "equalize" and it looks all fine and dandy.
The kernel has the interface defined, but apparently there's never actually
been any implementation for it (only a never merged patch in the 2.4 era).
I'm suggesting to drop the code to give any potential users of this feature
the benefit of receiving a proper error message. I see it unlikely that
this will be implemented in the near future, but if it ever happens
reviving the iproute2 side should be as easy as git revert this patch.

Macvlan can now optionally support forwarding between its
ports, if they are in "bridge" mode. This adds support
for this option to "ip link add", "ip link set" and "ip
-d link show".
The default mode in the kernel is now "vepa" mode, meaning
"virtual ethernet port aggregator". This mode is used
together with the "hairpin" mode of an ethernet bridge
that the parent of the macvlan device is connected to.
All frames still get sent out to the external interface,
but the adjacent bridge is able to send them back on
the same wire in hairpin mode, so the macvlan ports
are able to see each other, which the bridge can be
configured to monitor and control traffic between
all macvlan instances. Multicast traffic coming in
from the external interface is checked for the source
MAC address and only delivered to ports that have not
yet seen it.
In bridge mode, macvlan will send all multicast traffic
to other interfaces that are also in bridge mode but
not to those in vepa mode, which get them on the way
back from the hairpin.
The third supported mode is "private", which prevents
communication between macvlans even if the adjacent
bridge is in hairpin mode. This behavior is closer to
the original implementation of macvlan but stricly
maintains isolation.

Unless promote_secondaries has been active deleting the primary address of
an interface will automatically delete all the secondary addresses.
In the case where ip flush requests the primary then secondary addresses to
be removed - which is the order the addresses are returned by the kernel -
this will cause an error as by the time the request to remove a secondary
address is made it will be missing as it will have been deleted in the
course of deleting the primary address.
This approach to solving this problem orders requests for the
deletion of secondary addresses before primary ones providing
rtnl_dump_filter_l(), a version of rtnl_dump_filter() that
iterates over a list of filters. And by providing two specialised
filters print_addrinfo_secondary() and print_addrinfo_primary().
rtnl_dump_filter_l() first iterates over all addresses using
print_addrinfo_secondary(), which appends secondary addresses to the
request buffer. Then again using print_addrinfo_primary() which appends
primary addresses.
This approach should work regardless of it promote_secondaries is
active or not. And regardless of if any primary of secondary addresses
are present or not.

The iptables code supports a "no shared libs" mode where it can be used
without requiring dlfcn related functionality. This adds similar support
to iproute2 so that it can easily be used on systems like nommu Linux (but
obviously with a few limitations -- no dynamic plugins).
Rather than modify every location that uses dlfcn.h, I hooked the dlfcn.h
header with stub functions when shared library support is disabled. Then
symbol lookup is done via a local static lookup table (which is generated
automatically at build time) so that internal symbols can be found.

t's not a big problem, but it makes a better show in 'ip link show' on
CAN interfaces :-)
I also moved __PF(CAN,can) in ll_proto.c to the same position where it
can be found in if_ether.h .
The only thing i did not know if the __PF(CAN,can) in ll_types.c needs
to be put in #ifdef ARPHDR_CAN like __PF(HWX25,hwx25) is or not. You
definitely know that better than me.
"ip -6 tunnel show" displays only ip6ip6 tunnels not ip4ip6 tunnels
- it should display all irrespective of proto.
This is because the default tunnel proto is initialized to IPPROTO_IPV6 in ip6_tnl_parm_init() which is fine for a 'add' command but not for 'show'. This patch overrides proto with 0 signifying 'mode any' as the default in case of a 'show'.
please commit my patch below to the iproutes package. It just an incorrect
check so that adding an isatap tunnel with remote works, since it's needed if
one wants to use stateless autoconf. The current check makes tunnel mode
isatap unusable for all client users.
