* IB/mad: Fix incorrect access to items on local_listSean Hefty2008-01-25
| | | | | | | | | | | | | | | | | | | | In cancel_mads(), MADs are moved from the wait_list and local_list to a cancel_list for processing. However, the structures on these two lists are not the same. The wait_list references struct ib_mad_send_wr_private, but local_list references struct ib_mad_local_private. Cancel_mads() treats all items moved to the cancel_list as struct ib_mad_send_wr_private. This leads to a system crash when requests are moved from the local_list to the cancel_list. Fix this by leaving local_list alone. All requests on the local_list have completed are just awaiting processing by a queued worker thread. Bug (crash) reported by Dotan Barak <dotanb@dev.mellanox.co.il>. Problem with local_list access reported by Robert Reynolds <rreynolds@opengridcomputing.com>.

* IB/mad: Enable loopback of DR SMP responses from userspaceSteve Welch2008-01-25
| | | | | | | | | | | | | | | The local loopback of an outgoing DR SMP response is limited to those that originate at the driver specific SMA implementation during the driver specific process_mad() function. This patch enables a returning DR SMP originating in userspace (or elsewhere) to be delivered to the local managment stack. In this specific case the driver process_mad() function does not consume or process the MAD, so a reponse mad has not be created and the original MAD must manually be copied to the MAD buffer that is to be handed off to the local agent.

* IPoIB/cm: Add connected mode support for devices without SRQsPradeep Satyanarayana2008-01-25
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Some IB adapters (notably IBM's eHCA) do not implement SRQs (shared receive queues). The current IPoIB connected mode support only works on devices that support SRQs. Fix this by adding support for using the receive queue of each connected mode receive QP. The disadvantage of this compared to using an SRQ is that it means a full queue of receives must be posted for each remote connected mode peer, which means that total memory usage is potentially much higher than when using SRQs. To manage this, add a new module parameter "max_nonsrq_conn_qp" that limits the number of connections allowed per interface. The rest of the changes are fairly straightforward: we use a table of struct ipoib_cm_rx to hold all the active connections, and put the table index of the connection in the high bits of receive WR IDs. This is needed because we cannot rely on the struct ib_wc.qp field for non-SRQ receive completions. Most of the rest of the changes just test whether or not an SRQ is available, and post receives or find received packets in the right place depending on the answer. Cleaning up dead connections actually becomes simpler, because we do not have to do the "last WQE reached" dance that is required to destroy QPs attached to an SRQ. We just move the QP to the error state and wait for all pending receives to be flushed.

| | | | | | | | | | | | | | | Commit 23b9c1ab ("Infiniband: make ipath driver use default driver groups.") introduced a bug in the ipath driver where ipath_device_create_group() fell through into the error path, even on success, which meant that the sysfs groups it created would always get removed right away. This made ipath_device_remove_group() hit the BUG_ON() in sysfs_remove_group() when it tried to remove those groups a second time.

According to a comment in the BSD source, this is true for the external clock on almost all every board. - writes to a reserved bit - doesn't follow the initialization procedure specified in chapter 6.11.1 of the HIFN hardware users guide - doesn't allow to use the PCI clock This patch adds a module parameter to specify the reference clock (pci or external) and its frequency and uses that to calculate the optimum multiplier to reach the maximal speed. By default it uses the external clock and assumes a speed of 66MHz, which effectively halfs the frequency currently used.

This is suboptimal because ablkcipher refers to two things. On the one hand it refers to the top-level ablkcipher interface with requests. On the other hand it refers to and algorithm type underneath. As it is you cannot request a synchronous block cipher algorithm with the ablkcipher interface on top. This is a problem because we want to be able to eventually phase out the blkcipher top-level interface. This patch fixes this by making ABLKCIPHER its own type, just as we have distinct types for HASH and DIGEST. The type it associated with the algorithm implementation only. Which top-level interface is used for synchronous block ciphers is then determined by the mask that's used. If it's a specific mask then the old blkcipher interface is given, otherwise we go with the new ablkcipher interface. Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au>

| * | [CRYPTO] hifn: Schedule callback invocation to tasklet.Evgeniy Polyakov2008-01-10
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch forces HIFN driver to invoke crypto request callbacks from tasklet (softirq context) instead of hardirq context, since network stack expects it to be called from bottom halves. It is done by simply scheduling callback invocation via dedicated tasklet. Workqueue solution was dropped because of tooo slow rescheduling performance (7 times slower than tasklet, for mode details one can check this link: http://tservice.net.ru/~s0mbre/blog/devel/other/2007_11_09.html). Driver passed all AES and DES tests in tcryt.c module. Signed-off-by: Evgeniy Polyakov <johnpol@2ka.mipt.ru> Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au>
| * | [CRYPTO] geode: Add fallback for unsupported modesSebastian Siewior2008-01-10
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The Geode AES crypto engine supports only 128 bit long key. This patch adds fallback for other key sizes which are required by the AES standard.

| * | [CRYPTO] geode: relax in busy loop and care about return valueSebastian Siewior2008-01-10
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The code waits in a busy loop until the hardware finishes the encryption or decryption process. This wants a cpu_relax() :) The busy loop finishes either if the encryption is done or if the counter is zero. If the latter is true than the hardware failed. Since this should not happen, leave sith a BUG(). Signed-off-by: Sebastian Siewior <sebastian@breakpoint.cc> Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au>
| * | [CRYPTO] geode: use consistent IV copySebastian Siewior2008-01-10
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | It is enough if the IV is copied before and after the while loop. With DM-Crypt is seems not be required to save the IV after encrytion because a new one is used in the request (dunno about other users). It is not save to load the IV within while loop and not save afterwards because we mill end up with the wrong IV if the request goes consists of more than one page.
