| * IB/cm: Modify interface to send MRAs in response to duplicate messagesSean Hefty2007-10-091-2/+5
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The IB CM provides a message received acknowledged (MRA) message that can be sent to indicate that a REQ or REP message has been received, but will require more time to process than the timeout specified by those messages. In many cases, the application may not know how long it will take to respond to a CM message, but the majority of the time, it will usually respond before a retry has been sent. Rather than sending an MRA in response to all messages just to handle the case where a longer timeout is needed, it is more efficient to queue the MRA for sending in case a duplicate message is received. This avoids sending an MRA when it is not needed, but limits the number of times that a REQ or REP will be resent. It also provides for a simpler implementation than generating the MRA based on a timer event. (That is, trying to send the MRA after receiving the first REQ or REP if a response has not been generated, so that it is received at the remote side before a duplicate REQ or REP has been received) Signed-off-by: Sean Hefty <sean.hefty@intel.com> Signed-off-by: Roland Dreier <rolandd@cisco.com>

| * IB/umad: Fix bit ordering and 32-on-64 problems on big endian systemsRoland Dreier2007-10-091-1/+21
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The declaration of struct ib_user_mad_reg_req.method_mask[] exported to userspace was an array of __u32, but the kernel internally treated it as a bitmap made up of longs. This makes a difference for 64-bit big-endian kernels, where numbering the bits in an array of__u32 gives: |31.....0|63....31|95....64|127...96| while numbering the bits in an array of longs gives: |63..............0|127............64| 64-bit userspace can handle this by just treating method_mask[] as an array of longs, but 32-bit userspace is really stuck: the meaning of the bits in method_mask[] depends on whether the kernel is 32-bit or 64-bit, and there's no sane way for userspace to know that. Fix this by updating <rdma/ib_user_mad.h> to make it clear that method_mask[] is an array of longs, and using a compat_ioctl method to convert to an array of 64-bit longs to handle the 32-on-64 problem. This fixes the interface description to match existing behavior (so working binaries continue to work) in almost all situations, and gives consistent semantics in the case of 32-bit userspace that can run on either a 32-bit or 64-bit kernel, so that the same binary can work for both 32-on-32 and 32-on-64 systems.

| * IB/umad: Add P_Key index supportRoland Dreier2007-10-091-0/+48
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Add support for setting the P_Key index of sent MADs and getting the P_Key index of received MADs. This requires a change to the layout of the ABI structure struct ib_user_mad_hdr, so to avoid breaking compatibility, we default to the old (unchanged) ABI and add a new ioctl IB_USER_MAD_ENABLE_PKEY that allows applications that are aware of the new ABI to opt into using it. We plan on switching to the new ABI by default in a year or so, and this patch adds a warning that is printed when an application uses the old ABI, to push people towards converting to the new ABI.

| * | [NET]: make netlink user -> kernel interface synchroniousDenis V. Lunev2007-10-103-5/+5

This change was inspired by the talk with Alexey Kuznetsov about current netlink messages processing. He says that he was badly wrong when introduced asynchronious user -> kernel communication. The call netlink_unicast is the only path to send message to the kernel netlink socket. But, unfortunately, it is also used to send data to the user. Before this change the user message has been attached to the socket queue and sk->sk_data_ready was called. The process has been blocked until all pending messages were processed. The bad thing is that this processing may occur in the arbitrary process context. This patch changes nlk->data_ready callback to get 1 skb and force packet processing right in the netlink_unicast. Kernel -> user path in netlink_unicast remains untouched. EINTR processing for in netlink_run_queue was changed. It forces rtnl_lock drop, but the process remains in the cycle until the message will be fully processed. So, there is no need to use this kludges now. Signed-off-by: Denis V.

The construction is done by concatenating the encrypted result from the cipher with the output from the hash, as is used by the IPsec ESP protocol. The authenc algorithm exists as a template with four parameters: authenc(auth, authsize, enc, enckeylen). The authentication algorithm, the authentication size (i.e., truncating the output of the authentication algorithm), the encryption algorithm, and the encryption key length. Both the size field and the key length field are in bytes. For example, AES-128 with SHA1-HMAC would be represented by authenc(hmac(sha1), 12, cbc(aes), 16) The key for the authenc algorithm is the concatenation of the keys for the authentication algorithm with the encryption algorithm. For the above example, if a key of length 36 bytes is given, then hmac(sha1) would receive the first 20 bytes while the last 16 would be given to cbc(aes).

| * | [IPSEC]: Move common code into xfrm_alloc_spiHerbert Xu2007-10-101-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch moves some common code that conceptually belongs to the xfrm core from af_key/xfrm_user into xfrm_alloc_spi. In particular, the spin lock on the state is now taken inside xfrm_alloc_spi. Previously it also protected the construction of the response PF_KEY/XFRM messages to user-space. This is inconsistent as other identical constructions are not protected by the state lock. This is bad because they in fact should be protected but only in certain spots (so as not to hold the lock for too long which may cause packet drops).

| * | [NETNS]: Move some code into __init section when CONFIG_NET_NS=nPavel Emelyanov2007-10-102-0/+10
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | With the net namespaces many code leaved the __init section, thus making the kernel occupy more memory than it did before. Since we have a config option that prohibits the namespace creation, the functions that initialize/finalize some netns stuff are simply not needed and can be freed after the boot. Currently, this is almost not noticeable, since few calls are no longer in __init, but when the namespaces will be merged it will be possible to free more code. I propose to use the __net_init, __net_exit and __net_initdata "attributes" for functions/variables that are not used if the CONFIG_NET_NS is not set to save more space in memory. The exiting functions cannot just reside in the __exit section, as noticed by David, since the init section will have references on it and the compilation will fail due to modpost checks. These references can exist, since the init namespace never dies and the exit callbacks are never called. So I introduce the __exit_refok attribute just like it is already done with the __init_refok.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The replay counter is one of only two remaining things in the output code that requires a lock on the xfrm state (the other being the crypto). This patch moves it into the generic xfrm_output so we can remove the lock from the transforms themselves. Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au> Signed-off-by: David S.

| * | [IPSEC]: Move common output code to xfrm_outputHerbert Xu2007-10-101-0/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Most of the code in xfrm4_output_one and xfrm6_output_one are identical so this patch moves them into a common xfrm_output function which will live in net/xfrm. In fact this would seem to fix a bug as on IPv4 we never reset the network header after a transform which may upset netfilter later on.

| * | [AF_IUCV]: postpone receival of iucv-packetsUrsula Braun2007-10-101-0/+7
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | AF_IUCV socket programs may waste Linux storage, because af_iucv allocates an skb whenever posted by the receive callback routine and receives the message immediately. Message receival is now postponed if data from previous callbacks has not yet been transferred to the receiving socket program. Instead a message handle is saved in a message queue as a reminder. Once messages could be given to the receiving socket program, there is an additional checking for entries in the message queue, followed by skb allocation and message receival if applicable.
