2005-10-08[PATCH] gfp flags annotations - part 1Al Viro
- added typedef unsigned int __nocast gfp_t; - replaced __nocast uses for gfp flags with gfp_t - it gives exactly the same warnings as far as sparse is concerned, doesn't change generated code (from gcc point of view we replaced unsigned int with typedef) and documents what's going on far better.

2005-10-05[IPSEC]: Document that policy direction is derived from the index.Herbert Xu
Here is a patch that adds a helper called xfrm_policy_id2dir to document the fact that the policy direction can be and is derived from the index. This is based on a patch by YOSHIFUJI Hideaki and 210313105@suda.edu.cn. Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au> Signed-off-by: David S. Miller <davem@davemloft.net>
2005-10-04[AF_KEY]: fix sparse gfp nocast warningsRandy Dunlap
Fix implicit nocast warnings in net/key code: net/key/af_key.c:195:27: warning: implicit cast to nocast type net/key/af_key.c:1439:28: warning: implicit cast to nocast type Signed-off-by: Randy Dunlap <rdunlap@xenotime.net> Signed-off-by: David S. Miller <davem@davemloft.net>
2005-06-20[IPSEC]: Add XFRM_STATE_NOPMTUDISC flagHerbert Xu
This patch adds the flag XFRM_STATE_NOPMTUDISC for xfrm states. It is similar to the nopmtudisc on IPIP/GRE tunnels. It only has an effect on IPv4 tunnel mode states. For these states, it will ensure that the DF flag is always cleared. This is primarily useful to work around ICMP blackholes. In future this flag could also allow a larger MTU to be set within the tunnel just like IPIP/GRE tunnels. This could be useful for short haul tunnels where temporary fragmentation outside the tunnel is desired over smaller fragments inside the tunnel.

2005-06-20[IPSEC]: Add xfrm_init_stateHerbert Xu
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.

We hold two references (one from xfrm_state_alloc(), one from xfrm_state_hold()), but only drop one. We need to take the reference because the reference from xfrm_state_alloc() can be dropped by __xfrm_state_delete(), so the fix is to drop both references on error. Same problem in xfrm_user.c.

2005-06-18[IPSEC] Use XFRM_MSG_* instead of XFRM_SAP_*Herbert Xu
This patch removes XFRM_SAP_* and converts them over to XFRM_MSG_*. The netlink interface is meant to map directly onto the underlying xfrm subsystem. Therefore rather than using a new independent representation for the events we can simply use the existing ones from xfrm_user. Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au>
2005-06-18[IPSEC] Turn km_event.data into a unionHerbert Xu
This patch turns km_event.data into a union. This makes code that uses it clearer. Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au>
2005-06-18[IPSEC] Fix xfrm to pfkey SA state conversionHerbert Xu
This patch adjusts the SA state conversion in af_key such that XFRM_STATE_ERROR/XFRM_STATE_DEAD will be converted to SADB_STATE_DEAD instead of SADB_STATE_DYING. According to RFC 2367, SADB_STATE_DYING SAs can be turned into mature ones through updating their lifetime settings. Since SAs which are in the states XFRM_STATE_ERROR/XFRM_STATE_DEAD cannot be resurrected, this value is unsuitable. Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au>

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!
