[IPSEC]: Fix crypto_alloc_comp error checking

2007-11-07T12:15:03Z

The function crypto_alloc_comp returns an errno instead of NULL to indicate error. So it needs to be tested with IS_ERR. This is based on a patch by Vicen� Beltran Querol. Signed-off-by: Herbert Xu Signed-off-by: David S. Miller

cleanup asm/scatterlist.h includes

2007-11-02T07:47:06Z

Not architecture specific code should not #include . This patch therefore either replaces them with #include or simply removes them if they were unused. Signed-off-by: Adrian Bunk Signed-off-by: Jens Axboe

[IPSEC]: Move IP protocol setting from transforms into xfrm4_input.c

2007-10-10T23:55:56Z

This patch makes the IPv4 x->type->input functions return the next protocol instead of setting it directly. This is identical to how we do things in IPv6 and will help us merge common code on the input path. Signed-off-by: Herbert Xu Signed-off-by: David S. Miller

[IPSEC]: Move IP length/checksum setting out of transforms

2007-10-10T23:55:56Z

This patch moves the setting of the IP length and checksum fields out of the transforms and into the xfrmX_output functions. This would help future efforts in merging the transforms themselves. It also adds an optimisation to ipcomp due to the fact that the transport offset is guaranteed to be zero. Signed-off-by: Herbert Xu Signed-off-by: David S. Miller

[IPSEC]: Get rid of ipv6_{auth,esp,comp}_hdr

2007-10-10T23:55:55Z

This patch removes the duplicate ipv6_{auth,esp,comp}_hdr structures since they're identical to the IPv4 versions. Duplicating them would only create problems for ourselves later when we need to add things like extended sequence numbers. I've also added transport header type conversion headers for these types which are now used by the transforms. Signed-off-by: Herbert Xu Signed-off-by: David S. Miller

[IPSEC]: Use IPv6 calling convention as the convention for x->mode->output

2007-10-10T23:55:54Z

The IPv6 calling convention for x->mode->output is more general and could help an eventual protocol-generic x->type->output implementation. This patch adopts it for IPv4 as well and modifies the IPv4 type output functions accordingly. It also rewrites the IPv6 mac/transport header calculation to be based off the network header where practical. Signed-off-by: Herbert Xu Signed-off-by: David S. Miller

[IPSEC]: Set skb->data to payload in x->mode->output

2007-10-10T23:55:54Z

This patch changes the calling convention so that on entry from x->mode->output and before entry into x->type->output skb->data will point to the payload instead of the IP header. This is essentially a redistribution of skb_push/skb_pull calls with the aim of minimising them on the common path of tunnel + ESP. It'll also let us use the same calling convention between IPv4 and IPv6 with the next patch. Signed-off-by: Herbert Xu Signed-off-by: David S. Miller

[XFRM]: Add module alias for transformation type.

2007-07-11T05:15:43Z

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.

[SK_BUFF]: Introduce skb_copy_to_linear_data{_offset}

2007-04-26T05:28:29Z

To clearly state the intent of copying to linear sk_buffs, _offset being a overly long variant but interesting for the sake of saving some bytes. Signed-off-by: Arnaldo Carvalho de Melo

[SK_BUFF]: unions of just one member don't get anything done, kill them

2007-04-26T05:26:20Z

Renaming skb->h to skb->transport_header, skb->nh to skb->network_header and skb->mac to skb->mac_header, to match the names of the associated helpers (skb[_[re]set]_{transport,network,mac}_header). Signed-off-by: Arnaldo Carvalho de Melo Signed-off-by: David S. Miller
