Instead of having a fixed buffer of 16 bytes for the interface name,
tailor size of new ll_cache entry using the interface name's actual
length. This also makes sure the following call to strcpy() is safe.

This big patch was compiled by vimgrepping for memset calls and changing
to C99 initializer if applicable. One notable exception is the
initialization of union bpf_attr in tc/tc_bpf.c: changing it would break
for older gcc versions (at least <=3.4.6).
Calls to memset for struct rtattr pointer fields for parse_rtattr*()
were just dropped since they are not needed.
The changes here allowed the compiler to discover some unused variables,
so get rid of them, too.

Two commands are added:
- ip netns list-id
- ip monitor nsid
A cache is also added to remember the association between the iproute2 netns
name (from /var/run/netns/) and the nsid.
To avoid interfering with the rth socket, a new rtnl socket (rtnsh) is used to
get nsid (we may send rtnl request during listing on rth).
Example:
$ ip netns list-id
nsid 0 (iproute2 netns name: foo)
$ ip monitor nsid
Deleted nsid 0 (iproute2 netns name: foo)
nsid 16 (iproute2 netns name: bar)

ll_index can return -1 but was declared unsigned.
rt_addr_n2a had unused length parameter
|
| |
|
|
|
| |
Make ll_ functions faster by having a name hash, and allow
for deletion. Also, allow them to work without calling ll_init_map.

The address was being stored but not used by current code.

Both rtnl_talk and rtnl_dump had a callback for handling portions
of netlink message that do not match the correct pid or seq.
But this callback was never used by any part of iproute2 so remove
it.

In preparation for adding name hash:
* add const
* use same types in cache as ifinfomsg
* rename idxmap to ll_cache
|
| |
|
|
|
|
|
| |
Avoid initializing the LL map (which involves a costly RTNL dump)
multiple times. This can happen when running in batch mode.

ip addrlabel outputs if%d names due to missing init call:
$ ip addrlabel s
prefix a::42/128 dev if4 label 1000
Also, ip did not accept "if%d" interfaces on input.

After calling ll_init_map, all of the information stored in the link-layer map
can be retrieved by function calls (ll_index_to_*), except for the link-layer
address. This patch fills the gap by adding a ll_index_to_addr function.
Changes welcome.

In order to support these new flags add current
linux/if.h into the directory with the local copies.
This caused troubles with outdated redefinitions from net/if.h
so I've removed the dependency on it.
