2017-04-14esp6: Reorganize esp_outputSteffen Klassert1-0/+3
We need a fallback for ESP at layer 2, so split esp6_output into generic functions that can be used at layer 3 and layer 2 and use them in esp_output. We also add esp6_xmit which is used for the layer 2 fallback. Signed-off-by: Steffen Klassert <steffen.klassert@secunet.com>

2013-11-07net: move pskb_put() to core codeMathias Krause1-2/+0
This function has usage beside IPsec so move it to the core skbuff code. While doing so, give it some documentation and change its return type to 'unsigned char *' to be in line with skb_put().

2013-10-29net: esp{4,6}: get rid of struct esp_dataMathias Krause1-7/+0
struct esp_data consists of a single pointer, vanishing the need for it to be a structure. Fold the pointer into 'data' direcly, removing one level of pointer indirection.

The padlen member of struct esp_data is always zero. Get rid of it.

2013-09-20esp.h: Remove extern from function prototypesJoe Perches1-1/+1
There are a mix of function prototypes with and without extern in the kernel sources. Standardize on not using extern for function prototypes. Function prototypes don't need to be written with extern. extern is assumed by the compiler. Its use is as unnecessary as using auto to declare automatic/local variables in a block.

2008-01-31[IPSEC]: Use crypto_aead and authenc in ESPHerbert Xu1-46/+8
This patch converts ESP to use the crypto_aead interface and in particular the authenc algorithm. This lays the foundations for future support of combined mode algorithms. Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au> Signed-off-by: David S. Miller <davem@davemloft.net>
2007-11-02cleanup asm/scatterlist.h includesAdrian Bunk1-1/+1
Not architecture specific code should not #include <asm/scatterlist.h>. This patch therefore either replaces them with #include <linux/scatterlist.h> or simply removes them if they were unused. Signed-off-by: Adrian Bunk <bunk@kernel.org> Signed-off-by: Jens Axboe <jens.axboe@oracle.com>
2007-10-10[IPSEC]: Get rid of ipv6_{auth,esp,comp}_hdrHerbert Xu1-0/+7
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 <herbert@gondor.apana.org.au> Signed-off-by: David S. Miller <davem@davemloft.net>
2007-10-10[IPSEC] esp: Remove keys from esp_data structureHerbert Xu1-7/+0
The keys are only used during initialisation so we don't need to carry them in esp_data. Since we don't have to allocate them again, there is no need to place a limit on the authentication key length anymore. This patch also kills the unused auth.icv member.

2007-04-25[NET]: Move generic skbuff stuff from XFRM code to generic codeDavid Howells1-2/+0
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.

2006-09-22[IPSEC] esp: Defer output IV initialization to first use.David S. Miller1-2/+3
First of all, if the xfrm_state only gets used for input packets this entropy is a complete waste. Secondly, it is often the case that a configuration loads many rules (perhaps even dynamically) and they don't all necessarily ever get used. This get_random_bytes() call was showing up in the profiles for xfrm_state inserts which is how I noticed this. Signed-off-by: David S. Miller <davem@davemloft.net>
2006-09-21[IPSEC]: Use HMAC template and hash interfaceHerbert Xu1-12/+16
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.

2006-09-21[IPSEC] ESP: Use block ciphers where applicableHerbert Xu1-1/+1
This patch converts IPSec/ESP to use the new block cipher type where applicable. Similar to the HMAC conversion, existing algorithm names have been kept for compatibility. Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au>
2006-09-21[IPSEC]: Move linux/crypto.h inclusion out of net/xfrm.hHerbert Xu1-0/+1
The header file linux/crypto.h is only needed by a few files so including it in net/xfrm.h (which is included by half of the networking stack) is a waste. This patch moves it out of net/xfrm.h and into the specific header files that actually need it. Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au>
2005-04-16Linux-2.6.12-rc2v2.6.12-rc2Linus Torvalds1-0/+59
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!
