xen-netback: fix fragment detection in checksum setup

2013-12-06T01:31:40Z

The code to detect fragments in checksum_setup() was missing for IPv4 and too eager for IPv6. (It transpires that Windows seems to send IPv6 packets with a fragment header even if they are not a fragment - i.e. offset is zero, and M bit is not set). This patch also incorporates a fix to callers of maybe_pull_tail() where skb->network_header was being erroneously added to the length argument.

inet: fix addr_len/msg->msg_namelen assignment in recv_error and rxpmtu functions

2013-11-23T22:46:23Z

Commit bceaa90240b6019ed73b49965eac7d167610be69 ("inet: prevent leakage of uninitialized memory to user in recv syscalls") conditionally updated addr_len if the msg_name is written to. The recv_error and rxpmtu functions relied on the recvmsg functions to set up addr_len before. As this does not happen any more we have to pass addr_len to those functions as well and set it to the size of the corresponding sockaddr length. This broke traceroute and such.

ipv6: enable IPV6_FLOWLABEL_MGR for getsockopt

2013-11-08T18:42:57Z

It is already possible to set/put/renew a label with IPV6_FLOWLABEL_MGR and setsockopt. This patch add the possibility to get information about this label (current value, time before expiration, etc). It helps application to take decision for a renew or a release of the label. v2: * Add spin_lock to prevent race condition * return -ENOENT if no result found * check if flr_action is GET v3: * move the spin_lock to protect only the relevant code Signed-off-by: Florent Fourcot Acked-by: Hannes Frederic Sowa Signed-off-by: David S.

ipv6: split inet6_hash_frag for netfilter and initialize secrets with net_get_random_once

2013-10-23T21:01:40Z

Defer the fragmentation hash secret initialization for IPv6 like the previous patch did for IPv4. Because the netfilter logic reuses the hash secret we have to split it first. Thus introduce a new nf_hash_frag function which takes care to seed the hash secret. Cc: David S.

ipv6: split inet6_ehashfn to hash functions per compilation unit

2013-10-19T23:45:34Z

This patch splits the inet6_ehashfn into separate ones in ipv6/inet6_hashtables.o and ipv6/udp.o to ease the introduction of seperate secrets keys later. Cc: Eric Dumazet Cc: "David S. Miller" Signed-off-by: Hannes Frederic Sowa Signed-off-by: David S. Miller

ip*.h: Remove extern from function prototypes

2013-09-21T18:01:38Z

There are a mix of function prototypes with and without extern in the kernel sources. Standardize on not using extern for function prototypes. Function prototypes don't need to be written with extern. extern is assumed by the compiler. Its use is as unnecessary as using auto to declare automatic/local variables in a block.

net: ipv6: Add IPv6 support to the ping socket.

2013-05-26T04:07:49Z

This adds the ability to send ICMPv6 echo requests without a raw socket. The equivalent ability for ICMPv4 was added in 2011. Instead of having separate code paths for IPv4 and IPv6, make most of the code in net/ipv4/ping.c dual-stack and only add a few IPv6-specific bits (like the protocol definition) to a new net/ipv6/ping.c. Hopefully this will reduce divergence and/or duplication of bugs in the future. Caveats: - Setting options via ancillary data (e.g., using IPV6_PKTINFO to specify the outgoing interface) is not yet supported. - There are no separate security settings for IPv4 and IPv6; everything is controlled by /proc/net/ipv4/ping_group_range. - The proc interface does not yet display IPv6 ping sockets properly. Tested with a patched copy of ping6 and using raw socket calls. Compiles and works with all of CONFIG_IPV6={n,m,y}. Signed-off-by: Lorenzo Colitti Signed-off-by: David S. Miller
