net: Convert net_ratelimit uses to net__ratelimited

2012-05-15T17:45:03Z

Standardize the net core ratelimited logging functions. Coalesce formats, align arguments. Change a printk then vprintk sequence to use printf extension %pV. Signed-off-by: Joe Perches Signed-off-by: David S. Miller

net: cleanup unsigned to unsigned int

2012-04-15T16:44:40Z

Use of "unsigned int" is preferred to bare "unsigned" in net tree. Signed-off-by: Eric Dumazet Signed-off-by: David S. Miller

ipv4: fix checkpatch errors

2012-04-15T16:37:19Z

Fix checkpatch errors of the following type: * ERROR: "foo * bar" should be "foo *bar" * ERROR: "(foo*)" should be "(foo *)" Signed-off-by: Daniel Baluta Signed-off-by: David S. Miller

net: ipv4: Standardize prefixes for message logging

2012-03-13T00:05:21Z

Add #define pr_fmt(fmt) as appropriate. Add "IPv4: ", "TCP: ", and "IPsec: " to appropriate files. Standardize on "UDPLite: " for appropriate uses. Some prefixes were previously "UDPLITE: " and "UDP-Lite: ". Add KBUILD_MODNAME ": " to icmp and gre. Remove embedded prefixes as appropriate. Add missing "\n" to pr_info in gre.c.

net: Convert printks to pr_

2012-03-12T06:42:51Z

Use a more current kernel messaging style. Convert a printk block to print_hex_dump. Coalesce formats, align arguments. Use %s, __func__ instead of embedding function names. Some messages that were prefixed with _close are now prefixed with _fini. Some ah4 and esp messages are now not prefixed with "ip ". The intent of this patch is to later add something like #define pr_fmt(fmt) "IPv4: " fmt. to standardize the output messages. Text size is trivially reduced.

ipv4: Fix wrong order of ip_rt_get_source() and update iph->daddr.

2012-02-10T20:12:12Z

This patch fix a bug which introduced by commit ac8a4810 (ipv4: Save nexthop address of LSRR/SSRR option to IPCB.).In that patch, we saved the nexthop of SRR in ip_option->nexthop and update iph->daddr until we get to ip_forward_options(), but we need to update it before ip_rt_get_source(), otherwise we may get a wrong src.

ipv4: Save nexthop address of LSRR/SSRR option to IPCB.

2011-11-24T00:19:32Z

We can not update iph->daddr in ip_options_rcv_srr(), It is too early. When some exception ocurred later (eg. in ip_forward() when goto sr_failed) we need the ip header be identical to the original one as ICMP need it. Add a field 'nexthop' in struct ip_options to save nexthop of LSRR or SSRR option. Signed-off-by: Li Wei Signed-off-by: David S. Miller

ipv4: fix for ip_options_rcv_srr() daddr update.

2011-11-09T20:59:00Z

When opt->srr_is_hit is set skb_rtable(skb) has been updated for 'nexthop' and iph->daddr should always equals to skb_rtable->rt_dst holds, We need update iph->daddr either. Signed-off-by: Li Wei Signed-off-by: David S. Miller

ip_options_compile: properly handle unaligned pointer

2011-05-31T22:11:02Z

The current code takes an unaligned pointer and does htonl() on it to make it big-endian, then does a memcpy(). The problem is that the compiler decides that since the pointer is to a __be32, it is legal to optimize the copy into a processor word store. However, on an architecture that does not handled unaligned writes in kernel space, this produces an unaligned exception fault. The solution is to track the pointer as a "char *" (which removes a bunch of unpleasant casts in any case), and then just use put_unaligned_be32() to write the value to memory.

ipv4: Remove rt->rt_dst reference from ip_forward_options().

At this point iph->daddr equals what rt->rt_dst would hold. Signed-off-by: David S. Miller
