Linux-2.6.12-rc2 Initial git repository build. I'm not bothering with the full history, even though we have it. We can create a separate "historical" git archive of that later if we want to, and in the meantime it's about 3.2GB when imported into git - space that would just make the early git days unnecessarily complicated, when we don't have a lot of good infrastructure for it. Let it rip!

ipv4/ipv6: Fix FSF address in file headers Several files refer to an old address for the Free Software Foundation in the file header comment. Resolve by replacing the address with the URL <http://www.gnu.org/licenses/> so that we do not have to keep updating the header comments anytime the address changes.

ipv6: Handle PMTU in ICMP error handlers. One tricky issue on the ipv6 side vs. ipv4 is that the ICMP callouts to handle the error pass the 32-bit info cookie in network byte order whereas ipv4 passes it around in host byte order. Like the ipv4 side, we have two helper functions. One for when we have a socket context and one for when we do not. ip6ip6 tunnels are not handled here, because they handle PMTU events by essentially relaying another ICMP packet-too-big message back to the original sender. This patch allows us to get rid of rt6_do_pmtu_disc(). It handles all kinds of situations that simply cannot happen when we do the PMTU update directly using a fully resolved route. In fact, the "plen == 128" check in ip6_rt_update_pmtu() can very likely be removed or changed into a BUG_ON() check. We should never have a prefixed ipv6 route when we get there. Another piece of strange history here is that TCP and DCCP, unlike in ipv4, never invoke the update_pmtu() method from their ICMP error handlers. This is incredibly astonishing since this is the context where we have the most accurate context in which to make a PMTU update, namely we have a fully connected socket and associated cached socket route.

esp6: Avoid skb_cow_data whenever possible This patch tries to avoid skb_cow_data on esp6. On the encrypt side we add the IPsec tailbits to the linear part of the buffer if there is space on it. If there is no space on the linear part, we add a page fragment with the tailbits to the buffer and use separate src and dst scatterlists. On the decrypt side, we leave the buffer as it is if it is not cloned. With this, we can avoid a linearization of the buffer in most of the cases.

[SK_BUFF]: Convert skb->tail to sk_buff_data_t So that it is also an offset from skb->head, reduces its size from 8 to 4 bytes on 64bit architectures, allowing us to combine the 4 bytes hole left by the layer headers conversion, reducing struct sk_buff size to 256 bytes, i.e. 4 64byte cachelines, and since the sk_buff slab cache is SLAB_HWCACHE_ALIGN... :-) Many calculations that previously required that skb->{transport,network, mac}_header be first converted to a pointer now can be done directly, being meaningful as offsets or pointers.

esp6: Avoid skb_cow_data whenever possible This patch tries to avoid skb_cow_data on esp6. On the encrypt side we add the IPsec tailbits to the linear part of the buffer if there is space on it. If there is no space on the linear part, we add a page fragment with the tailbits to the buffer and use separate src and dst scatterlists. On the decrypt side, we leave the buffer as it is if it is not cloned. With this, we can avoid a linearization of the buffer in most of the cases.

Some KERN_<LEVEL> uses are changed to KERN_DEBUG. This may have some negative impact on messages that were emitted at KERN_INFO that are not not enabled at all unless DEBUG is defined or dynamic_debug is enabled. Even so, these messages are now _not_ emitted by default. This also eliminates the use of the net_msg_warn sysctl "/proc/sys/net/core/warnings". For backward compatibility, the sysctl is not removed, but it has no function.

esp6: Avoid skb_cow_data whenever possible This patch tries to avoid skb_cow_data on esp6. On the encrypt side we add the IPsec tailbits to the linear part of the buffer if there is space on it. If there is no space on the linear part, we add a page fragment with the tailbits to the buffer and use separate src and dst scatterlists. On the decrypt side, we leave the buffer as it is if it is not cloned. With this, we can avoid a linearization of the buffer in most of the cases.

networking: make skb_push & __skb_push return void pointers It seems like a historic accident that these return unsigned char *, and in many places that means casts are required, more often than not. Make these functions return void * and remove all the casts across the tree, adding a (u8 *) cast only where the unsigned char pointer was used directly, all done with the following spatch: @@ expression SKB, LEN; typedef u8; identifier fn = { skb_push, __skb_push, skb_push_rcsum }; @@ - *(fn(SKB, LEN)) + *(u8 *)fn(SKB, LEN) @@ expression E, SKB, LEN; identifier fn = { skb_push, __skb_push, skb_push_rcsum }; type T; @@ - E = ((T *)(fn(SKB, LEN))) + E = fn(SKB, LEN) @@ expression SKB, LEN; identifier fn = { skb_push, __skb_push, skb_push_rcsum }; @@ - fn(SKB, LEN)[0] + *(u8 *)fn(SKB, LEN) Note that the last part there converts from push(...)[0] to the more idiomatic *(u8 *)push(...).

[IPSEC]: Kill unused decap state argument This patch removes the decap_state argument from the xfrm input hook. Previously this function allowed the input hook to share state with the post_input hook. The latter has since been removed. The only purpose for it now is to check the encap type. However, it is easier and better to move the encap type check to the generic xfrm_rcv function. This allows us to get rid of the decap state argument altogether.

This also fixes a minor bug for transport-mode ESP where the IP payload length is set to the correct value minus the header length (with extension headers for IPv6).

We can create a separate "historical" git archive of that later if we want to, and in the meantime it's about 3.2GB when imported into git - space that would just make the early git days unnecessarily complicated, when we don't have a lot of good infrastructure for it.

Updating the pmtu on ICMPV6_DEST_UNREACH is wrong in any case, it causes strangely fragmented packets.

This allows all namespaces to apply routing and iptables rules to kernel-originated traffic in that namespaces by matching UID 0. This is better than using the UID of the kernel socket that is sending the traffic, because the UID of kernel sockets created at namespace creation time (e.g., the per-processor ICMP and TCP sockets) is the UID of the user that created the socket, which might not be mapped in the namespace.

esp: Use a synchronous crypto algorithm on offloading. We need a fallback algorithm for crypto offloading to a NIC. This is because packets can be rerouted to other NICs that don't support crypto offloading. The fallback is going to be implemented at layer2 where we know the final output device but can't handle asynchronous returns fron the crypto layer.

net: ipv6: Standardize prefixes for message logging Add #define pr_fmt(fmt) as appropriate. Add "IPv6: " to appropriate files. Convert printk(KERN_<LEVEL> to pr_<level> (but not KERN_DEBUG). Standardize on "%s: " not "%s(): " when emitting __func__. Use "%s: ", __func__ instead of embedding function name. Coalesce formats, align arguments. ADDRCONF output is now prefixed with "IPv6: " Signed-off-by: Joe Perches <joe@perches.com> Signed-off-by: David S. Miller <davem@davemloft.net>

Linux-2.6.12-rc2 Initial git repository build. I'm not bothering with the full history, even though we have it. We can create a separate "historical" git archive of that later if we want to, and in the meantime it's about 3.2GB when imported into git - space that would just make the early git days unnecessarily complicated, when we don't have a lot of good infrastructure for it. Let it rip!

[XFRM]: Add module alias for transformation type. It is clean-up for XFRM type modules and adds aliases with its protocol: ESP, AH, IPCOMP, IPIP and IPv6 for IPsec ROUTING and DSTOPTS for MIPv6 It is almost the same thing as XFRM mode alias, but it is added new defines XFRM_PROTO_XXX for preprocessing since some protocols are defined as enum.
