Now network timestamps use ktime_t infrastructure, we can add a new ioctl() SIOCGSTAMPNS command to get timestamps in 'struct timespec'. User programs can thus access to nanosecond resolution. Signed-off-by:

This patch eliminates some duplicate code for the verification of receive checksums between UDP-Lite and UDP. It does this by introducing __skb_checksum_complete_head which is identical to __skb_checksum_complete_head apart from the fact that it takes a length parameter rather than computing the first skb->len bytes. As a result UDP-Lite will be able to use hardware checksum offload for packets which do not use partial coverage checksums. It also means that UDP-Lite loopback no longer does unnecessary checksum verification. If any NICs start support UDP-Lite this would also start working automatically. This patch removes the assumption that msg_flags has MSG_TRUNC clear upon entry in recvmsg. Signed-off-by:

This reverts the changeset [IPV6]: UDPv6 checksum. We always need to check UDPv6 checksum because it is mandatory. The sk_filter optimisation has nothing to do whether we verify the checksum. It simply postpones it to the point when the user calls recv or poll. Signed-off-by: -

1) Some sysctl vars are declared __read_mostly 2) We can avoid updating stack[] when doing an AVL lookup only. lookup() macro is extended to receive a second parameter, that may be NULL in case of a pure lookup (no need to save the AVL path). This removes unnecessary instructions, because compiler knows if this _stack parameter is NULL or not. text size of net/ipv4/inetpeer.o is 2063 bytes instead of 2107 on x86_64 Signed-off-by: -

The Newton-Raphson method is quadratically convergent so only a small fixed number of steps are necessary. Therefore it is faster to unroll the loop. Since div64_64 is no longer inline it won't cause code explosion. Also fixes a bug that can occur if x^2 was bigger than 32 bits. Signed-off-by:

The inet6_ifaddr for source address of RS is leaked if the address is not an optimistic address. Signed-off-by:
-
Neil Horman authored
Nominally an autoconfigured IPv6 address is added to an interface in the Tentative state (as per RFC 2462). Addresses in this state remain in this state while the Duplicate Address Detection process operates on them to determine their uniqueness on the network. During this period, these tentative addresses may not be used for communication, increasing the time before a node may be able to communicate on a network. Using Optimistic Duplicate Address Detection, autoconfigured addresses may be used immediately for communication on the network, as long as certain rules are followed to avoid conflicts with other nodes during the Duplicate Address Detection process.

ip6_tunnel before supporting IPv4/IPv6 tunnel allows only IPPROTO_IPV6 in configurations from userland. This allows userland to set IPPROTO_IPIP and 0(wildcard). ip6_tunnel only handles allowed inner protocols. Signed-off-by:

Some notes - Protocol number IPPROTO_IPIP is used for IPv4 over IPv6 packets. - If IP6_TNL_F_USE_ORIG_TCLASS is set, TOS in IPv4 header is copied to Traffic Class in outer IPv6 header on xmit. - IP6_TNL_F_USE_ORIG_FLOWLABEL is ignored on xmit of IPv4 packets, because IPv4 header does not have flow label. - Kernel sends ICMP error if IPv4 packet is too big on xmit, even if DF flag is not set.

If the user passes MSG_TRUNC in via msg_flags, return the full packet size not the truncated size. Idea from Herbert Xu and Thomas Graf. Signed-off-by: -

We currently use a special structure (struct skb_timeval) and plain 'struct timeval' to store packet timestamps in sk_buffs and struct sock. This has some drawbacks : - Fixed resolution of micro second. - Waste of space on 64bit platforms where sizeof(struct timeval)=16 I suggest using ktime_t that is a nice abstraction of high resolution time services, currently capable of nanosecond resolution. As sizeof(ktime_t) is 8 bytes, using ktime_t in 'struct sock' permits a 8 byte shrink of this structure on 64bit architectures. Some other structures also benefit from this size reduction (struct ipq in ipv4/ip_fragment.c, struct frag_queue in ipv6/reassembly.c, ...) Once this ktime infrastructure adopted, we can more easily provide nanosecond resolution on top of it. (ioctl SIOCGSTAMPNS and/or SO_TIMESTAMPNS/SCM_TIMESTAMPNS) Note : this patch includes a bug correction in compat_sock_get_timestamp() where a "err = 0;" was missing (so this syscall returned -ENOENT instead of 0) Signed-off-by:
