This chunks out the accept_queue and tcp_listen_opt code and moves them to net/core/request_sock.c and include/net/request_sock.h, to make it useful for other transport protocols, DCCP being the first one to use it. Next patches will rename tcp_listen_opt to accept_sock and remove the inline tcp functions that just call a reqsk_queue_ function.

Ok, this one just renames some stuff to have a better namespace and to dissassociate it from TCP: struct open_request -> struct request_sock tcp_openreq_alloc -> reqsk_alloc tcp_openreq_free -> reqsk_free tcp_openreq_fastfree -> __reqsk_free With this most of the infrastructure closely resembles a struct sock methods subset.

Kept this first changeset minimal, without changing existing names to ease peer review. Basicaly tcp_openreq_alloc now receives the or_calltable, that in turn has two new members: ->slab, that replaces tcp_openreq_cachep ->obj_size, to inform the size of the openreq descendant for a specific protocol The protocol specific fields in struct open_request were moved to a class hierarchy, with the things that are common to all connection oriented PF_INET protocols in struct inet_request_sock, the TCP ones in tcp_request_sock, that is an inet_request_sock, that is an open_request. I.e. this uses the same approach used for the struct sock class hierarchy, with sk_prot indicating if the protocol wants to use the open_request infrastructure by filling in sk_prot->rsk_prot with an or_calltable. Results? Performance is improved and TCP v4 now uses only 64 bytes per open request minisock, down from 96 without this patch :-) Next changeset will rename some of the structs, fields and functions mentioned above, struct or_calltable is way unclear, better name it struct request_sock_ops, s/struct open_request/struct request_sock/g, etc. Signed-off-by: NArnaldo Carvalho de Melo <acme@ghostprotocols.net> Signed-off-by: NDavid S.

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.

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: NHerbert Xu <herbert@gondor.apana.org.au>

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: NHerbert Xu <herbert@gondor.apana.org.au>

This patch ensures that the hard state/policy expire notifications are only sent when the state/policy is successfully removed from their respective tables. As it is, it's possible for a state/policy to both expire through reaching a hard limit, as well as being deleted by the user. Note that this behaviour isn't actually forbidden by RFC 2367. However, it is a quality of implementation issue. As an added bonus, the restructuring in this patch will help eventually in moving the expire notifications from softirq context into process context, thus improving their reliability. One important side-effect from this change is that SAs reaching their hard byte/packet limits are now deleted immediately, just like SAs that have reached their hard time limits. Previously they were announced immediately but only deleted after 30 seconds. This is bad because it prevents the system from issuing an ACQUIRE command until the existing state was deleted by the user or expires after the time is up. In the scenario where the expire notification was lost this introduces a 30 second delay into the system for no good reason. Signed-off-by: NHerbert Xu <herbert@gondor.apana.org.au>

This patch alows you to change the source address of icmp error messages. It applies cleanly to 2.6.11.11 and retains the default behaviour. In the old (default) behaviour icmp error messages are sent with the ip of the exiting interface. The new behaviour (when the sysctl variable is toggled on), it will send the message with the ip of the interface that received the packet that caused the icmp error. This is the behaviour network administrators will expect from a router. It makes debugging complicated network layouts much easier. Also, all 'vendor routers' I know of have the later behaviour.

Userland layer-2 tunneling devices allocated through the TUNTAP driver (drivers/net/tun.c) have a type of ARPHRD_NONE, and have no link-layer address. The kernel complains at regular interval when IPv6 Privacy extension are enabled because it can't find an hardware address : Dec 29 11:02:04 auguste kernel: __ipv6_regen_rndid(idev=cb3e0c00): cannot get EUI64 identifier; use random bytes. IPv6 Privacy extensions should probably be disabled on that sort of device. They won't work anyway. If userland wants a more usual Ethernet-ish interface with usual IPv6 autoconfiguration, it will use a TAP device with an emulated link-layer and a random hardware address rather than a TUN device. As far as I could fine, TUN virtual device from TUNTAP is the very only sort of device using ARPHRD_NONE as kernel device type.

Changing the sysctl net.core.dev_weight has no effect because the weight of the backlog devices is set during initialization and never changed.
