2005-11-02[IPoIB] don't compile debug code if debugging isn't enabledRoland Dreier
Don't build ipoib_mcast_iter_ functions if CONFIG_INFINIBAND_IPOIB_DEBUG is not enabled -- their only callers will not be built either. Also move the prototype for ipoib_open() to ipoib.h to fix a sparse warning. Signed-off-by: Roland Dreier <rolandd@cisco.com>
2005-11-02IB: Add SCSI RDMA Protocol (SRP) initiatorRoland Dreier
Add an InfiniBand SCSI RDMA Protocol (SRP) initiator. This driver is used to talk talk to InfiniBand SRP targets (storage devices). Signed-off-by: Roland Dreier <rolandd@cisco.com>
2005-11-02[IPoIB] remove unneeded initializations to 0Roland Dreier
Shrink our source and .text a little by removing a few assignments of NULL and 0 to memory that is already cleared as part of the allocation. Signed-off-by: Roland Dreier <rolandd@cisco.com>
2005-11-02[IB] kzalloc() conversionsRoland Dreier
Replace kmalloc()+memset(,0,) with kzalloc(), for a net savings of 35 source lines and about 500 bytes of text. Signed-off-by: Roland Dreier <rolandd@cisco.com>
2005-10-31[IPoIB] cleanups: fix comment, remove useless variablesRoland Dreier
Minor cleanups: fix a misleading comment, and get rid of attr_mask variables that are only used to hold constants (just use the constants directly). Signed-off-by: Roland Dreier <rolandd@cisco.com>
2005-10-29[IPoIB] use spin_trylock_irqsave()Roland Dreier
Use spin_trylock_irqsave() in ipoib_start_xmit() instead of reinventing it out of local_irq_save(), spin_trylock() and local_irq_restore(). Signed-off-by: Roland Dreier <rolandd@cisco.com>
2005-10-28[IPoIB] Drop RX packets when out of memoryRoland Dreier
Change the way IPoIB handles RX packets when it can't allocate a new receive skbuff. If the allocation of a new receive skb fails, we now drop the packet we just received and repost the original receive skb. This means that the receive ring always stays full and we don't have to monkey around with trying to schedule a refill task for later. Signed-off-by: Roland Dreier <rolandd@cisco.com>
2005-10-18[IPoIB] Improve ipoib_timeout() outputRoland Dreier
Use jiffies_to_msecs() so we print a human-readable time so we don't have to worry about what HZ is configured to, and print out a few values to make post-mortem analysis easier. Signed-off-by: Roland Dreier <rolandd@cisco.com>
2005-10-17[IPoIB] Rename ipoib_create_qp() -> ipoib_init_qp() and fix error cleanupRoland Dreier
ipoib_create_qp() no longer creates IPoIB's QP, so it shouldn't destroy the QP on failure -- that unwinding happens elsewhere, so the current code can cause a double free. While we're at it, the function's name should match what it actually does, so rename it to ipoib_init_qp(). Signed-off-by: Roland Dreier <rolandd@cisco.com>
2005-09-28[IPoIB] Rename IPoIB's path_lookup() to avoid name clashesRoland Dreier
Rename IPoIB driver's path_lookup() to ipoib_path_lookup() to avoid a clashes with the kernel global path_lookup(). We don't hit this with the current kernel source, but some external patches seem to trigger this, and it's cleaner to avoid clashing with global names anyway.

2005-09-20[PATCH] IPoIB: Don't flush workqueue from within workqueueRoland Dreier
ipoib_mcast_restart_task() is always called from within the single-threaded IPoIB workqueue, so flushing the workqueue from within the function can lead to a recursion overflow. But since we're running in a single-threaded workqueue, we're already synchronized against other items in the workqueue, so just get rid of the flush in ipoib_mcast_restart_task(). Signed-off-by: Roland Dreier <rolandd@cisco.com>
2005-09-18[PATCH] IPoIB: Fix SA client retransmission strategyHal Rosenstock
We got a little mixed up with what the backoff member holds in the IPoIB multicast group structure: sometimes it was used as a number of seconds, and sometimes it was used as a number of jiffies. Fix the code so that backoff is always in seconds. Signed-off-by: Hal Rosenstock <halr@voltaire.com> Signed-off-by: Roland Dreier <rolandd@cisco.com>
2005-09-18[PATCH] IPoIB: fix module removal raceMichael S. Tsirkin
Since ipoib uses queue_delayed_work to run flush task on port state events, it must flush scheduled work after unregistering the event handler. Signed-off-by: Michael S. Tsirkin <mst@mellanox.co.il> Signed-off-by: Roland Dreier <rolandd@cisco.com>
2005-09-07[PATCH] IPoIB: fix memory leakMichael S. Tsirkin
Fix IPoIB memory leak on device removal. Signed-off-by: Michael S. Tsirkin <mst@mellanox.co.il> Signed-off-by: Roland Dreier <rolandd@cisco.com>
2005-08-26[PATCH] IB: move include files to include/rdmaRoland Dreier
Move the InfiniBand headers from drivers/infiniband/include to include/rdma. This allows InfiniBand-using code to live elsewhere, and lets us remove the ugly EXTRA_CFLAGS include path from the InfiniBand Makefiles. Signed-off-by: Roland Dreier <rolandd@cisco.com>
2005-08-26[PATCH] IPoIB: Fix device removal raceMichael S. Tsirkin
Currently we may have work scheduled in default kernel workqueue when the device is going down. The device could get freed before this workqueue gets serviced. I am actually seeing this causing system hangs. The following patch fixes this by using ipoib_workqueue which gets flushed when the device is going down. Signed-off-by: Michael S. Tsirkin <mst@mellanox.co.il> Signed-off-by: Roland Dreier <rolandd@cisco.com>
2005-08-26[PATCH] IPoIB: Set full membership bit in P_KeysRoland Dreier
Always make sure that the full membership bit is set in the P_Keys that IPoIB uses. This makes sure that all hosts join the correct multicast groups so that hosts that are partial partition members can talk to the rest of the network. Signed-off-by: Roland Dreier <rolandd@cisco.com>
2005-08-26[PATCH] IB: Remove unnecessary includes of <linux/version.h>Olaf Hering
changing CONFIG_LOCALVERSION rebuilds too much, for no appearent reason. Remove unneeded includes of <linux/version.h>. Signed-off-by: Olaf Hering <olh@suse.de> Signed-off-by: Roland Dreier <rolandd@cisco.com>

2005-08-26[PATCH] IB: Add copyright noticesRoland Dreier
Make some lawyers happy and add copyright notices for people who forgot to include them when they actually touched the code. Signed-off-by: Roland Dreier <rolandd@cisco.com>
2005-07-28[PATCH] [IPoIB] Handle sending of unicast RARP responsesHal Rosenstock
RARP replies are another valid case where IPoIB may need to send a unicast packet with no neighbour structure. Signed-off-by: Hal Rosenstock <halr@voltaire.com> Signed-off-by: Roland Dreier <rolandd@cisco.com>
2005-07-27[IB/ipoib]: Fix unsigned comparisons to handle wraparoundRoland Dreier

2005-04-16[PATCH] IPoIB: convert to debugfsRoland Dreier
Convert IPoIB to use debugfs instead of its own custom debugging filesystem. Signed-off-by: Roland Dreier <roland@topspin.com> Signed-off-by: Andrew Morton <akpm@osdl.org> Signed-off-by: Linus Torvalds <torvalds@osdl.org>
2005-04-16[PATCH] IPoIB: fix static rate calculationRoland Dreier
Correct and simplify calculation of static rate. We need to round up the quotient of (local_rate - path_rate) / path_rate. To round up we add (path_rate - 1) to the numerator, so the quotient simplifies to (local_rate - 1) / path_rate. No idea how I came up with the old formula.

2005-04-16[PATCH] IPoIB: set skb->mac.raw on receiveHal Rosenstock
Set skb->mac.raw on receive. This fixes crashes when this is dereferenced, for example by netfilter or when PF_PACKET is used.

2005-04-16Linux-2.6.12-rc2Linus Torvalds
Initial git repository build. I'm not bothering with the full history, even though we have it. We can create a separate "historical" git archive of that later if we want to, and in the meantime it's about 3.2GB when imported into git - space that would just make the early git days unnecessarily complicated, when we don't have a lot of good infrastructure for it. Let it rip!
