2007-04-25[SK_BUFF]: unions of just one member don't get anything done, kill themArnaldo Carvalho de Melo1-1/+1
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).

2007-04-25[SK_BUFF]: Introduce skb_transport_header(skb)Arnaldo Carvalho de Melo1-1/+1
For the places where we need a pointer to the transport header, it is still legal to touch skb->h.raw directly if just adding to, subtracting from or setting it to another layer header. Signed-off-by: Arnaldo Carvalho de Melo <acme@redhat.com> Signed-off-by: David S. Miller <davem@davemloft.net>

2007-04-25[SK_BUFF]: Introduce ipv6_hdr(), remove skb->nh.ipv6hArnaldo Carvalho de Melo1-1/+1
Now the skb->nh union has just one member, .raw, i.e. it is just like the skb->mac union, strange, no? I'm just leaving it like that till the transport layer is done with, when we'll rename skb->mac.raw to skb->mac_header (or ->mac_header_offset?), ditto for ->{h,nh}.

2006-09-22[XFRM] STATE: Add a hook to find offset to be inserted header in outbound.Masahide NAKAMURA1-0/+1
On current kernel, ip6_find_1stfragopt() is used by IPv6 IPsec to find offset to be inserted header in outbound for transport mode. (BTW, no usage may be needed for IPv4 case.) Mobile IPv6 requires another logic for routing header and destination options header respectively. This patch is common platform for the offset and adopts it to IPsec. Based on MIPL2 kernel patch.

2006-07-12[IPCOMP]: Fix truesize after decompressionHerbert Xu1-1/+2
The truesize check has uncovered the fact that we forgot to update truesize after pskb_expand_head. Unfortunately pskb_expand_head can't update it for us because it's used in all sorts of different contexts, some of which would not allow truesize to be updated by itself. So the solution for now is to simply update it in IPComp. This patch also changes skb_put to __skb_put since we've just expanded tailroom by exactly that amount so we know it's there (but gcc does not).

2006-06-17[NET]: Clean up skb_linearizeHerbert Xu1-8/+3
The linearisation operation doesn't need to be super-optimised. So we can replace __skb_linearize with __pskb_pull_tail which does the same thing but is more general. Also, most users of skb_linearize end up testing whether the skb is linear or not so it helps to make skb_linearize do just that. Some callers of skb_linearize also use it to copy cloned data, so it's useful to have a new function skb_linearize_cow to copy the data if it's either non-linear or cloned. Last but not least, I've removed the gfp argument since nobody uses it anymore. If it's ever needed we can easily add it back.

2006-06-17[IPSEC] proto: Move transport mode input path into xfrm_mode_transportHerbert Xu1-22/+5
Now that we have xfrm_mode objects we can move the transport mode specific input decapsulation code into xfrm_mode_transport. This removes duplicate code as well as unnecessary header movement in case of tunnel mode SAs since we will discard the original IP header immediately. 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). Of course the other neat thing is that we no longer have to allocate temporary buffers to hold the IP headers for ESP and IPComp.

2006-04-11[PATCH] for_each_possible_cpu: network codesKAMEZAWA Hiroyuki1-4/+4
for_each_cpu() actually iterates across all possible CPUs. We've had mistakes in the past where people were using for_each_cpu() where they should have been iterating across only online or present CPUs. This is inefficient and possibly buggy. We're renaming for_each_cpu() to for_each_possible_cpu() to avoid this in the future.

2006-04-01[IPSEC]: Kill unused decap state argumentHerbert Xu1-1/+1
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. Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au> Signed-off-by: David S. Miller <davem@davemloft.net>
2006-03-26[IPSEC]: Fix tunnel error handling in ipcomp6Herbert Xu1-0/+5
The error handling in ipcomp6_tunnel_create is broken in two ways: 1) If we fail to allocate an SPI (this should never happen in practice since there are plenty of 32-bit SPI values for us to use), we will still go ahead and create the SA. 2) When xfrm_init_state fails, we first of all may trigger the BUG_TRAP in __xfrm_state_destroy because we didn't set the state to DEAD. More importantly we end up returning the freed state as if we succeeded! This patch fixes them both. Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au> Signed-off-by: David S.

2005-09-01[CRYPTO]: crypto_free_tfm() callers no longer need to check for NULLJesper Juhl1-2/+1
Since the patch to add a NULL short-circuit to crypto_free_tfm() went in, there's no longer any need for callers of that function to check for NULL. This patch removes the redundant NULL checks and also a few similar checks for NULL before calls to kfree() that I ran into while doing the crypto_free_tfm bits. I've succesfuly compile tested this patch, and a kernel with the patch applied boots and runs just fine. When I posted the patch to LKML (and other lists/people on Cc) it drew the following comments : J. Bruce Fields commented "I've no problem with the auth_gss or nfsv4 bits.--b." Sridhar Samudrala said "sctp change looks fine." Herbert Xu signed off on the patch. So, I guess this is ready to be dropped into -mm and eventually mainline.

2005-06-20[IPSEC]: Add xfrm_init_stateHerbert Xu1-7/+2
This patch adds xfrm_init_state which is simply a wrapper that calls xfrm_get_type and subsequently x->type->init_state. It also gets rid of the unused args argument. Abstracting it out allows us to add common initialisation code, e.g., to set family-specific flags. The add_time setting in xfrm_user.c was deleted because it's already set by xfrm_state_alloc.

2005-04-16Linux-2.6.12-rc2v2.6.12-rc2Linus Torvalds1-0/+524
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!
