ipv6: coding style: comparison for equality with NULL

2015-03-31T17:51:54+00:00

The ipv6 code uses a mixture of coding styles. In some instances check for NULL pointer is done as x == NULL and sometimes as !x. !x is preferred according to checkpatch and this patch makes the code consistent by adopting the latter form. No changes detected by objdiff. Signed-off-by: Ian Morris Signed-off-by: David S. Miller

ipv6: ipv6_find_hdr restore prev functionality

2014-02-27T23:27:26+00:00

The commit 9195bb8e381d81d5a315f911904cdf0cfcc919b8 ("ipv6: improve ipv6_find_hdr() to skip empty routing headers") broke ipv6_find_hdr(). When a target is specified like IPPROTO_ICMPV6 ipv6_find_hdr() returns -ENOENT when it's found, not the header as expected. A part of IPVS is broken and possible also nft_exthdr_eval(). When target is -1 which it is most cases, it works. This patch exits the do while loop if the specific header is found so the nexthdr could be returned as expected.

ipv6: Correct comparisons and calculations using skb->tail and skb-transport_header

2013-05-29T06:49:07+00:00

This corrects an regression introduced by "net: Use 16bits for *_headers fields of struct skbuff" when NET_SKBUFF_DATA_USES_OFFSET is not set. In that case skb->tail will be a pointer whereas skb->transport_header will be an offset from head. This is corrected by using wrappers that ensure that comparisons and calculations are always made using pointers. Signed-off-by: Simon Horman Signed-off-by: David S. Miller

Merge branch 'master' of git://git.kernel.org/pub/scm/linux/kernel/git/jesse/openvswitch

2012-11-30T17:01:30+00:00

Conflicts: net/ipv6/exthdrs_core.c Jesse Gross says: ==================== This series of improvements for 3.8/net-next contains four components: * Support for modifying IPv6 headers * Support for matching and setting skb->mark for better integration with things like iptables * Ability to recognize the EtherType for RARP packets * Two small performance enhancements The movement of ipv6_find_hdr() into exthdrs_core.c causes two small merge conflicts. I left it as is but can do the merge if you want. The conflicts are: * ipv6_find_hdr() and ipv6_find_tlv() were both moved to the bottom of exthdrs_core.c. Both should stay. * A new use of ipv6_find_hdr() was added to net/netfilter/ipvs/ip_vs_core.c after this patch. The IPVS user has two instances of the old constant name IP6T_FH_F_FRAG which has been renamed to IP6_FH_F_FRAG. ==================== Signed-off-by: David S. Miller

ipv6: Update ipv6 static library with newly needed functions

UDP offload needs some additional functions to be in the static kernel for it work correclty. Move those functions into the core. Signed-off-by: Vlad Yasevich Signed-off-by: David S. Miller

ipv6: improve ipv6_find_hdr() to skip empty routing headers

2012-11-12T20:31:37+00:00

This patch prepares ipv6_find_hdr() function so that it could be able to skip routing headers, where segements_left is 0. This is required to handle multiple routing header case correctly when changing IPv6 addresses. Signed-off-by: Ansis Atteka Signed-off-by: Jesse Gross

ipv6: Move ipv6_find_hdr() out of Netfilter code.

2012-11-10T01:05:07+00:00

Open vSwitch will soon also use ipv6_find_hdr() so this moves it out of Netfilter-specific code into a more common location. Signed-off-by: Jesse Gross

ipv6: Add fragment reporting to ipv6_skip_exthdr().

2011-12-03T17:35:10+00:00

While parsing through IPv6 extension headers, fragment headers are skipped making them invisible to the caller. This reports the fragment offset of the last header in order to make it possible to determine whether the packet is fragmented and, if so whether it is a first or last fragment.
