* mlx4_en: Add driver for Mellanox ConnectX 10GbE NICYevgeny Petrilin2008-10-2312-0/+5370
| | | | | | | | | | | | | | The Mellanox ConnectX can operate as an InfiniBand adapter, as an Ethernet NIC, or as a Fibre Channel (FC) HBA. The kernel has a low-level driver, mlx4_core, which handles multiplexing access to the device, and there is also already an InfiniBad driver, mlx4_ib. This patch adds a new driver, mlx4_en, which implements a standard Ethernet NIC driver.

* mlx4_core: Multiple port type supportYevgeny Petrilin2008-10-239-11/+266
| | | | | | | | | | | | Multi-protocol adapters support different port types. Each consumer of mlx4_core queries for supported port types; in particular mlx4_ib can no longer assume that all physical ports belong to it. Port type is configured through a sysfs interface. When the type of a port is changed, all mlx4 interfaces are unregistered, and then registered again with the new port types.

* mlx4_core: Support multiple pre-reserved QP regionsYevgeny Petrilin2008-10-2213-29/+144
| | | | | | | | | | | | | For ethernet support, we need to reserve QPs for the ethernet and fibre channel driver. The QPs are reserved at the end of the QP table. (This way we assure that they are aligned to their size) We need to consider these reserved ranges in bitmap creation, so we extend the mlx4 bitmap utility functions to allow reserved ranges at both the bottom and the top of the range.

* mlx4_core: Add QP range reservation supportYevgeny Petrilin2008-10-105-18/+129
| | | | | | | | | | | | To allow allocating an aligned range of consecutive QP numbers, add an interface to reserve an aligned range of QP numbers and have the QP allocation function always take a QP number. This will be used for RSS support in the mlx4_en Ethernet driver and also potentially by IPoIB RSS support.

| * crypto: skcipher - Use RNG interface instead of get_random_bytesHerbert Xu2008-08-294-13/+75
| | | | | | | | | | | | | | This patch makes the IV generators use the new RNG interface so that the user can pick an RNG other than the default get_random_bytes. Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au>
| * crypto: rng - RNG interface and implementationNeil Horman2008-08-298-1/+754
| | | | | | | | | | | | | | | | | | | | | | | | This patch adds a random number generator interface as well as a cryptographic pseudo-random number generator based on AES. It is meant to be used in cases where a deterministic CPRNG is required. One of the first applications will be as an input in the IPsec IV generation process.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Add the ability to turn FIPS-compliant mode on or off at boot In order to be FIPS compliant, several check may need to be preformed that may be construed as unusefull in a non-compliant mode. This patch allows us to set a kernel flag incating that we are running in a fips-compliant mode from boot up. It also exports that mode information to user space via a sysctl (/proc/sys/crypto/fips_enabled). Tested successfully by me.

| | | | | | | | | | | | | | | | | | | | | | As it is we only test ciphers when combined with a mode. That means users that do not invoke a mode of operations may get an untested cipher. This patch tests all ciphers using the ECB mode so that simple cipher users such as ansi-cprng are also protected. Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au>

| * crypto: tcrypt - Add alg_test interfaceHerbert Xu2008-08-291-438/+1017
| | | | | | | | | | | | | | | | | | | | | | | | | | This patch creates a new interface algorithm testing. A test can be requested for a particular implementation of an algorithm. This is achieved by taking both the name of the algorithm and that of the implementation. The all-inclusive test has also been rewritten to no longer require a duplicate listing of all algorithms with tests. In that process a number of missing tests have also been discovered and rectified. Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au>
| * crypto: tcrypt - Abort and only log if there is an errorHerbert Xu2008-08-291-146/+200
| | | | | | | | | | | | | | | | | | | | | | | | The info printed is a complete waste of space when there is no error since it doesn't tell us anything that we don't already know. If there is an error, we can also be more verbose. In case that there is an error, this patch also aborts the test and returns the error to the caller. In future this will be used to algorithms at registration time. Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au>
| * crypto: crc32c - Use Intel CRC32 instructionAustin Zhang2008-08-293-0/+211
| | | | | | | | | | | | | | | | | | | | | | | | | | From NHM processor onward, Intel processors can support hardware accelerated CRC32c algorithm with the new CRC32 instruction in SSE 4.2 instruction set. The patch detects the availability of the feature, and chooses the most proper way to calculate CRC32c checksum. Byte code instructions are used for compiler compatibility. No MMX / XMM registers is involved in the implementation.

| | | | | | | | | | | | | | | | | | | | If tcrypt is to be used as a run-time integrity test, it needs to be more resilient in a hostile environment. For a start allocating 32K of physically contiguous memory is definitely out. This patch teaches it to use separate pages instead. Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au>
| * crypto: api - Display larval objects properlyHerbert Xu2008-08-291-2/+5
| | | | | | | | | | | | | | Rather than displaying larval objects as real objects, this patch makes them show up under /proc/crypto as of type larval. Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au>

However, that was removed (by me!) years ago, so mthca can just use pci_request_regions() and pci_release_regions() instead of its own much more complicated code that avoids requesting the MSI-X tables.

| | | | | * | | IPoIB: Use netif_tx_lock() and get rid of private tx_lock, LLTXRoland Dreier2008-09-305-107/+118

Not only do we want to get rid of LLTX, this actually causes problems because of the skb_orphan() done with this tx_lock held: some skb destructors expect to be run with interrupts enabled. The simplest fix for this is to get rid of the driver-private tx_lock and stop using LLTX. We kill off priv->tx_lock and use netif_tx_lock[_bh]() instead; the patch to do this is a tiny bit tricky because we need to update places that take priv->lock inside the tx_lock to disable IRQs, rather than relying on tx_lock having already disabled IRQs. Also, there are a couple of places where we need to disable BHs to make sure we have a consistent context to call netif_tx_lock() (since we no longer can use _irqsave() variants), and we also have to change ipoib_send_comp_handler() to call drain_tx_cq() through a timer rather than directly, because ipoib_send_comp_handler() runs in interrupt context and drain_tx_cq() must run in BH context so it can call netif_tx_lock().

| | | | | * | | IPoIB: Fix crash when path record fails after path flushRoland Dreier2008-09-261-4/+4

This change introduces a problem if the path record query triggered by fails, causing path->ah to become NULL. A later successful path query will then trigger WARN_ON() in path_rec_completion(), and crash because path->ah has already been freed, so the ipoib_put_ah() inside the lock in path_rec_completion() may actually drop the last reference (contrary to the comment that claims this is safe). Fix this by updating path->ah and freeing old_ah only when the path record query is successful. This prevents the neighbour AH and that path AH from getting out of sync.

Whenever a QP gets into error state, it is added to the QP error list of its respective CQ. If the error QP list of a CQ is not empty, poll_cq() generates flush CQEs before polling the actual CQ.
