* [DECNET]: Remove unnecessary initilization of unused variable entriesThomas Graf2005-06-19
| | | | | | | | This patch was supposed to be part of the neighbour tables related patchset but apparently got lost. Signed-off-by: Thomas Graf <tgraf@suug.ch> Signed-off-by: David S. Miller <davem@davemloft.net>
* [IPSEC]: Add XFRMA_SA/XFRMA_POLICY for delete notificationHerbert Xu2005-06-19
| | | | | | | | | | | | | | This patch changes the format of the XFRM_MSG_DELSA and XFRM_MSG_DELPOLICY notification so that the main message sent is of the same format as that received by the kernel if the original message was via netlink. This also means that we won't lose the byid information carried in km_event. Since this user interface is introduced by Jamal's patch we can still afford to change it.

* [NETLINK]: Correctly set NLM_F_MULTI without checking the pidJamal Hadi Salim2005-06-19
| | | | | | | | | | | This patch rectifies some rtnetlink message builders that derive the flags from the pid. It is now explicit like the other cases which get it right. Also fixes half a dozen dumpers which did not set NLM_F_MULTI at all. Signed-off-by: Jamal Hadi Salim <hadi@cyberus.ca> Signed-off-by: Thomas Graf <tgraf@suug.ch> Signed-off-by: David S.

* [NETLINK]: Introduce NLMSG_NEW macro to better handle netlink flagsThomas Graf2005-06-19
| | | | | | | | | | | | | | Introduces a new macro NLMSG_NEW which extends NLMSG_PUT but takes a flags argument. NLMSG_PUT stays there for compatibility but now calls NLMSG_NEW with flags == 0. NLMSG_PUT_ANSWER is renamed to NLMSG_NEW_ANSWER which now also takes a flags argument. Also converts the users of NLMSG_PUT_ANSWER to use NLMSG_NEW_ANSWER and fixes the two direct users of __nlmsg_put to either provide the flags or use NLMSG_NEW(_ANSWER).

* [NETLINK]: Neighbour table configuration and statistics via rtnetlinkThomas Graf2005-06-19
| | | | | | | | | | | | | | | | | | | | | | | | | | | To retrieve the neighbour tables send RTM_GETNEIGHTBL with the NLM_F_DUMP flag set. Every neighbour table configuration is spread over multiple messages to avoid running into message size limits on systems with many interfaces. The first message in the sequence transports all not device specific data such as statistics, configuration, and the default parameter set. This message is followed by 0..n messages carrying device specific parameter sets. Although the ordering should be sufficient, NDTA_NAME can be used to identify sequences. The initial message can be identified by checking for NDTA_CONFIG. The device specific messages do not contain this TLV but have NDTPA_IFINDEX set to the corresponding interface index. To change neighbour table attributes, send RTM_SETNEIGHTBL with NDTA_NAME set. Changeable attribute include NDTA_THRESH[1-3], NDTA_GC_INTERVAL, and all TLVs in NDTA_PARMS unless marked otherwise. Device specific parameter sets can be changed by setting NDTPA_IFINDEX to the interface index of the corresponding device. Signed-off-by: Thomas Graf <tgraf@suug.ch> Signed-off-by: David S.

* [NETLINK] Routing attribute related shortcutsThomas Graf2005-06-19
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | RTA_GET_U(32|64)(tlv) Assumes TLV is a u32/u64 field and returns its value. RTA_GET_[M]SECS(tlv) Assumes TLV is a u64 and transports jiffies converted to seconds or milliseconds and returns its value. RTA_PUT_U(32|64)(skb, type, value) Appends %value as fixed u32/u64 to %skb as TLV %type. RTA_PUT_[M]SECS(skb, type, jiffies) Converts %jiffies to secs/msecs and appends it as u64 to %skb as TLV %type. RTA_PUT_STRING(skb, type, string) Appends %NUL terminated %string to %skb as TLV %type. RTA_NEST(skb, type) Starts a nested TLV %type and returns the nesting handle. RTA_NEST_END(skb, nesting_handle) Finishes the nested TLV %nesting_handle, must be called symmetric to RTA_NEST(). Returns skb->len RTA_NEST_CANCEL(skb, nesting_handle) Cancel the nested TLV %nesting_handle and trim nested TLV from skb again, returns -1.

* [NET] Generalise tcp_listen_optArnaldo Carvalho de Melo2005-06-19
| | | | | | | | | | | | | 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.

* [NET] Rename open_request to request_sockArnaldo Carvalho de Melo2005-06-19
| | | | | | | | | | | | | | | | 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.

* [NET] Generalise TCP's struct open_request minisock infrastructureArnaldo Carvalho de Melo2005-06-19
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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: Arnaldo Carvalho de Melo <acme@ghostprotocols.net> Signed-off-by: David 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.

* [IPSEC] Use XFRM_MSG_* instead of XFRM_SAP_*Herbert Xu2005-06-19
| | | | | | | | | | 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>
* [IPSEC] Set byid for km_event in xfrm_get_policyHerbert Xu2005-06-19

* [IPSEC] Fix xfrm to pfkey SA state conversionHerbert Xu2005-06-19
| | | | | | | | | | | | | 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>
* [IPSEC] Kill spurious hard expire messagesHerbert Xu2005-06-19
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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: Herbert Xu <herbert@gondor.apana.org.au>

Note that d_name.name is nul- terminated by d_alloc(), and that sun_path is nul-terminated by unix_mkname(), so it is not necessary for the AVC to create nul- terminated copies or to alter audit_log_untrustedstring to take a length argument.
