genetlink: Build a generic netlink family module alias

2012-05-30T02:33:56+00:00

Generic netlink searches for -type- formatted aliases when requesting a module to
fulfill a protocol request (i.e. net-pf-16-proto-16-type-, where x is a type
value).  However generic netlink protocols have no well defined type numbers,
they have string names.  Modify genl_ctrl_getfamily to request an alias in the
format net-pf-16-proto-16-family- instead, where x is a generic string, and
add a macro that builds on the previously added MODULE_ALIAS_NET_PF_PROTO_NAME
macro to allow modules to specifify those generic strings.

Note, l2tp previously hacked together an net-pf-16-proto-16-type-l2tp alias
using the MODULE_ALIAS macro, with these updates we can convert that to use the
PROTO_NAME macro.

af_netlink: drop_monitor/dropwatch friendly

2012-04-24T04:35:14+00:00

Need to consume_skb() instead of kfree_skb() in netlink_dump() and
netlink_unicast_kernel() to avoid false dropwatch positives.

netlink: dont drop packet but consume it

2012-04-19T18:23:55+00:00

When we need to clone skb, we dont drop a packet.
Call consume_skb() to not confuse dropwatch.

netlink: fix races after skb queueing

2012-04-06T08:21:06+00:00

As soon as an skb is queued into socket receive_queue, another thread
can consume it, so we are not allowed to reference skb anymore, or risk
use after free.

genetlink: Stop using NLA_PUT*().

2012-04-01T22:43:25+00:00

These macros contain a hidden goto, and are thus extremely error
prone and make code hard to audit.

netlink: allow to pass data pointer to netlink_dump_start() callback

2012-02-26T19:10:44+00:00

This patch allows you to pass a data pointer that can be
accessed from the dump callback.

Netfilter is going to use this patch to provide filtered dumps
to user-space. This is specifically interesting in ctnetlink that
may handle lots of conntrack entries. We can save precious
cycles by skipping the conversion to TLV format of conntrack
entries that are not interesting for user-space.

More specifically, ctnetlink will include one operation to allow
to filter the dumping of conntrack entries by ctmark values.

netlink: add netlink_dump_control structure for netlink_dump_start()

2012-02-26T19:10:06+00:00

Davem considers that the argument list of this interface is getting
out of control. This patch tries to address this issue following
his proposal:

struct netlink_dump_control c = { .dump = dump, .done = done, ... };

netlink_dump_start(..., &c);

Suggested by David S. Miller.
