* [SCTP] sctp_connectx() API supportFrank Filz2005-06-20
| | | | | | | | | Implements sctp_connectx() as defined in the SCTP sockets API draft by tunneling the request through a setsockopt(). Signed-off-by: Frank Filz <ffilzlnx@us.ibm.com> Signed-off-by: Sridhar Samudrala <sri@us.ibm.com> Signed-off-by: David S. Miller <davem@davemloft.net>
* [TCP]: Fix sysctl_tcp_low_latencyDavid S. Miller2005-06-19
| | | | | | | When enabled, this should disable UCOPY prequeue'ing altogether, but it does not due to a missing test. Signed-off-by: David S. Miller <davem@davemloft.net>
* [IPV4]: [4/4] signed vs unsigned cleanup in net/ipv4/raw.cJesper Juhl2005-06-19
| | | | | | | | | | | | | | | | | | | This patch changes the type of the third parameter 'length' of the raw_send_hdrinc() function from 'int' to 'size_t'. This makes sense since this function is only ever called from one location, and the value passed as the third parameter in that location is itself of type size_t, so this makes the recieving functions parameter type match. Also, inside raw_send_hdrinc() the 'length' variable is used in comparisons with unsigned values and passed as parameter to functions expecting unsigned values (it's used in a single comparison with a signed value, but that one can never actually be negative so the patch also casts that one to size_t to stop gcc worrying, and it is passed in a single instance to memcpy_fromiovecend() which expects a signed int, but as far as I can see that's not a problem since the value of 'length' shouldn't ever exceed the value of a signed int).

* [IPV4]: [3/4] signed vs unsigned cleanup in net/ipv4/raw.cJesper Juhl2005-06-19
| | | | | | | | | | | | | | | | | | | This patch changes the type of the local variable 'i' in raw_probe_proto_opt() from 'int' to 'unsigned int'. The only use of 'i' in this function is as a counter in a for() loop and subsequent index into the msg->msg_iov[] array. Since 'i' is compared in a loop to the unsigned variable msg->msg_iovlen gcc -W generates this warning : net/ipv4/raw.c:340: warning: comparison between signed and unsigned Changing 'i' to unsigned silences this warning and is safe since the array index can never be negative anyway, so unsigned int is the logical type to use for 'i' and also enables a larger msg_iov[] array (but I don't know if that will ever matter).

* [IPV4]: [2/4] signed vs unsigned cleanup in net/ipv4/raw.cJesper Juhl2005-06-19
| | | | | | | | | | | | | | This patch gets rid of the following gcc -W warning in net/ipv4/raw.c : net/ipv4/raw.c:387: warning: comparison of unsigned expression < 0 is always false Since 'len' is of type size_t it is unsigned and can thus never be <0, and since this is obvious from the function declaration just a few lines above I think it's ok to remove the pointless check for len<0.

* [IPV4]: [1/4] signed vs unsigned cleanup in net/ipv4/raw.cJesper Juhl2005-06-19
| | | | | | | | | | | | | | This patch silences these two gcc -W warnings in net/ipv4/raw.c : net/ipv4/raw.c:517: warning: signed and unsigned type in conditional expression net/ipv4/raw.c:613: warning: signed and unsigned type in conditional expression It doesn't change the behaviour of the code, simply writes the conditional expression with plain 'if()' syntax instead of '? :' , but since this breaks it into sepperate statements gcc no longer complains about having both a signed and unsigned value in the same conditional expression.

* [SCTP]: Replace spin_lock_irqsave with spin_lock_bhHerbert Xu2005-06-19
| | | | | | | | | | | | | | | This patch replaces the spin_lock_irqsave call on the receive queue lock in SCTP with spin_lock_bh. Despite the proliferation of spin_lock_irqsave calls in this stack, it is only entered from the IPv4/IPv6 stack and user space. That is, it is never entered from hardirq context. The call in question is only called from recvmsg which means that IRQs aren't disabled. Therefore it is safe to replace it with spin_lock_bh.

* [IPV4/IPV6]: Replace spin_lock_irq with spin_lock_bhHerbert Xu2005-06-19
| | | | | | | | | | | | | In light of my recent patch to net/ipv4/udp.c that replaced the spin_lock_irq calls on the receive queue lock with spin_lock_bh, here is a similar patch for all other occurences of spin_lock_irq on receive/error queue locks in IPv4 and IPv6. In these stacks, we know that they can only be entered from user or softirq context. Therefore it's safe to disable BH only.

* [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]: 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.

* [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>

The main change is that it adds all the necessary APIs for WPA and WPA2 support. This work was entirely done by Jouni Malinen, so let's thank him for both his hard work and deep expertise on the subject ;-) This APIs obviously doesn't do much by itself and works in concert with driver support (Jouni already sent you the HostAP changes) and userspace (Jouni is updating wpa_supplicant). This is also orthogonal with the ongoing work on in-kernel IEEE support (but potentially useful). The patch is attached, tested with 2.6.11. Normally, I would ask you to push that directly in the kernel (99% of the patch has been on my web page for ages and it does not affect non-WPA stuff), but Jouni convinced me that it should bake a few weeks in wireless-2.6 first, so that other driver maintainers can get up to speed with it.
