* [IPSEC]: Add support for aes-ctr.Joy Latten2008-02-08
| | | | | | | | | The below patch allows IPsec to use CTR mode with AES encryption algorithm. Tested this using setkey in ipsec-tools. Signed-off-by: Joy Latten <latten@austin.ibm.com> Acked-by: Herbert Xu <herbert@gondor.apana.org.au> Signed-off-by: David S. Miller <davem@davemloft.net>
* [IPSEC]: Add support for combined mode algorithmsHerbert Xu2008-01-31
| | | | | | | | | | | | | | | | This patch adds support for combined mode algorithms with GCM being the first algorithm supported. Combined mode algorithms can be added through the xfrm_user interface using the new algorithm payload type XFRMA_ALG_AEAD. Each algorithms is identified by its name and the ICV length. For the purposes of matching algorithms in xfrm_tmpl structures, combined mode algorithms occupy the same name space as encryption algorithms. This is in line with how they are negotiated using IKE.

* cleanup asm/scatterlist.h includesAdrian Bunk2007-11-02

* SG: Change sg_set_page() to take length and offset argumentJens Axboe2007-10-24
| | | | | | | | | | Most drivers need to set length and offset as well, so may as well fold those three lines into one. Add sg_assign_page() for those two locations that only needed to set the page, where the offset/length is set outside of the function context. Signed-off-by: Jens Axboe <jens.axboe@oracle.com>

* [IPSEC] pfkey: Load specific algorithm in pfkey_add rather than allHerbert Xu2007-05-19
| | | | | | | | | | | | | This is a natural extension of the changeset [XFRM]: Probe selected algorithm only. which only removed the probe call for xfrm_user. This patch does exactly the same thing for af_key. In other words, we load the algorithm requested by the user rather than everything when adding xfrm states in af_key.

* [NET]: Revert sk_buff walker cleanups.David S. Miller2007-04-27
| | | | | | | | | | | This reverts eefa3906283a2b60a6d02a2cda593a7d7d7946c5 The simplification made in that change works with the assumption that the 'offset' parameter to these functions is always positive or zero, which is not true. It can be and often is negative in order to access SKB header values in front of skb->data. Signed-off-by: David S. Miller <davem@davemloft.net>
* [NET]: Clean up sk_buff walkers.Jean Delvare2007-04-26
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | I noticed recently that, in skb_checksum(), "offset" and "start" are essentially the same thing and have the same value throughout the function, despite being computed differently. Using a single variable allows some cleanups and makes the skb_checksum() function smaller, more readable, and presumably marginally faster. We appear to have many other "sk_buff walker" functions built on the exact same model, so the cleanup applies to them, too. Here is a list of the functions I found to be affected: net/appletalk/ddp.c:atalk_sum_skb() net/core/datagram.c:skb_copy_datagram_iovec() net/core/datagram.c:skb_copy_and_csum_datagram() net/core/skbuff.c:skb_copy_bits() net/core/skbuff.c:skb_store_bits() net/core/skbuff.c:skb_checksum() net/core/skbuff.c:skb_copy_and_csum_bit() net/core/user_dma.c:dma_skb_copy_datagram_iovec() net/xfrm/xfrm_algo.c:skb_icv_walk() net/xfrm/xfrm_algo.c:skb_to_sgvec() OTOH, I admit I'm a bit surprised, the cleanup is rather obvious so I'm really wondering if I am missing something. Can anyone please comment on this? Signed-off-by: Jean Delvare <jdelvare@suse.de> Signed-off-by: David S. Miller <davem@davemloft.net>
* [NET]: Move generic skbuff stuff from XFRM code to generic codeDavid Howells2007-04-26
| | | | | | | | | | | | Move generic skbuff stuff from XFRM code to generic code so that AF_RXRPC can use it too. The kdoc comments I've attached to the functions needs to be checked by whoever wrote them as I had to make some guesses about the workings of these functions.

* [XFRM]: Algorithm lookup using .compat nameMartin Willi2006-12-31
| | | | | | | | | | | Installing an IPsec SA using old algorithm names (.compat) does not work if the algorithm is not already loaded. When not using the PF_KEY interface, algorithms are not preloaded in xfrm_probe_algs() and installing a IPsec SA fails.

* [IPSEC]: Use HMAC template and hash interfaceHerbert Xu2006-09-20
| | | | | | | | | | | | | This patch converts IPsec to use the new HMAC template. The names of existing simple digest algorithms may still be used to refer to their HMAC composites. The same structure can be used by other MACs such as AES-XCBC-MAC. This patch also switches from the digest interface to hash.

* [IPSEC] ESP: Use block ciphers where applicableHerbert Xu2006-09-20

* [IPSEC]: Add compatibility algorithm name supportHerbert Xu2006-09-20
| | | | | | | | This patch adds a compatibility name field for each IPsec algorithm. This is needed when parameterised algorithms are used. For example, "md5" will become "hmac(md5)", and "aes" will become "cbc(aes)". Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au>

* [XFRM]: skb_cow_data() does not set proper owner for new skbs.Evgeniy Polyakov2005-05-19
| | | | | | | | | | | | | | | | | | | | | It looks like skb_cow_data() does not set proper owner for newly created skb. If we have several fragments for skb and some of them are shared(?) or cloned (like in async IPsec) there might be a situation when we require recreating skb and thus using skb_copy() for it. Newly created skb has neither a destructor nor a socket assotiated with it, which must be copied from the old skb. As far as I can see, current code sets destructor and socket for the first one skb only and uses truesize of the first skb only to increment sk_wmem_alloc value. If above "analysis" is correct then attached patch fixes that. Signed-off-by: Evgeniy Polyakov <johnpol@2ka.mipt.ru> Acked-by: Herbert Xu <herbert@gondor.apana.org.au> Signed-off-by: David S.

* Linux-2.6.12-rc2v2.6.12-rc2Linus Torvalds2005-04-16
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!
