inet: constify ip headers and in6_addr

2011-04-22T18:04:14+00:00

Add const qualifiers to structs iphdr, ipv6hdr and in6_addr pointers
where possible, to make code intention more obvious.

net: use CHECKSUM_NONE instead of magic number

2011-03-28T06:35:05+00:00

Two places in the kernel were doing skb->ip_summed = 0.

Change both to skb->ip_summed = CHECKSUM_NONE, which is more readable.

net: Put flowi_* prefix on AF independent members of struct flowi

2011-03-12T23:08:44+00:00

I intend to turn struct flowi into a union of AF specific flowi
structs.  There will be a common structure that each variant includes
first, much like struct sock_common.

This is the first step to move in that direction.

ipv6: ignore rtnl_unicast() return code

2011-02-25T22:00:23+00:00

rtnl_unicast() return value is not of interest, we can silently ignore
it, save some instructions and four byte on the stack.

net: use the macros defined for the members of flowi

2010-11-17T20:27:45+00:00

Use the macros defined for the members of flowi to clean the code up.

net: add a core netdev->rx_dropped counter

2010-10-05T21:47:55+00:00

In various situations, a device provides a packet to our stack and we
drop it before it enters protocol stack :
- softnet backlog full (accounted in /proc/net/softnet_stat)
- bad vlan tag (not accounted)
- unknown/unregistered protocol (not accounted)

We can handle a per-device counter of such dropped frames at core level,
and automatically adds it to the device provided stats (rx_dropped), so
that standard tools can be used (ifconfig, ip link, cat /proc/net/dev)

This is a generalization of commit 8990f468a (net: rx_dropped
accounting), thus reverting it.

net: rx_dropped accounting

2010-09-20T17:08:58+00:00

Under load, netif_rx() can drop incoming packets but administrators dont
have a chance to spot which device needs some tuning (RPS activation for
example)

This patch adds rx_dropped accounting in vlans and tunnels.

ipmr: dont corrupt lists

2010-06-07T09:57:14+00:00

ipmr_rules_exit() and ip6mr_rules_exit() free a list of items, but
forget to properly remove these items from list. List head is not
changed and still points to freed memory.

This can trigger a fault later when icmpv6_sk_exit() is called.

Fix is to either reinit list, or use list_del() to properly remove items
from list before freeing them.

bugzilla report : https://bugzilla.kernel.org/show_bug.cgi?id=16120

Introduced by commit d1db275dd3f6e4 (ipv6: ip6mr: support multiple
tables) and commit f0ad0860d01e (ipv4: ipmr: support multiple tables)
