2005-11-10[IPoIB] no need to set skb->dev right before freeing skbRoland Dreier1-13/+4
For cut-and-paste reasons, the IPoIB driver was setting skb->dev right before calling dev_kfree_skb_any(). Get rid of this. Signed-off-by: Roland Dreier <rolandd@cisco.com>
2005-11-10[IPoIB] add path record information in debugfsRoland Dreier5-49/+231
Add ibX_path files to debugfs that contain information about the IPoIB path cache. IPoIB ARP only gives GIDs, which the IPoIB driver must resolve to real IB paths through the ib_sa module. For debugging, when the ARP table looks OK but traffic isn't flowing, it's useful to be able to see if the resolution from GID to path worked. Also clean up the formatting of the existing _mcg debugfs files. Signed-off-by: Roland Dreier <rolandd@cisco.com>
2005-11-09[PATCH] changing CONFIG_LOCALVERSION rebuilds too much, for no good reasonOlaf Hering1-1/+0
This patch removes almost all inclusions of linux/version.h. The 3 #defines are unused in most of the touched files. A few drivers use the simple KERNEL_VERSION(a,b,c) macro, which is unfortunatly in linux/version.h. There are also lots of #ifdef for long obsolete kernels, this was not touched. In a few places, the linux/version.h include was move to where the LINUX_VERSION_CODE was used. quilt vi `find * -type f -name "*.[ch]"|xargs grep -El '(UTS_RELEASE|LINUX_VERSION_CODE|KERNEL_VERSION|linux/version.h)'|grep -Ev '(/(boot|coda|drm)/|~$)'` search pattern: /UTS_RELEASE\|LINUX_VERSION_CODE\|KERNEL_VERSION\|linux\/\(utsname\|version\).h Signed-off-by: Olaf Hering <olh@suse.de> Signed-off-by: Andrew Morton <akpm@osdl.org> Signed-off-by: Linus Torvalds <torvalds@osdl.org>

2005-11-03[IPoIB] don't compile debug code if debugging isn't enabledRoland Dreier3-1/+7
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>
2005-11-03IB: Add SCSI RDMA Protocol (SRP) initiatorRoland Dreier4-0/+1862
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 Dreier1-9/+2
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 Dreier2-9/+3
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 Dreier2-9/+7
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>
2005-10-30[IPoIB] use spin_trylock_irqsave()Roland Dreier1-4/+1
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>
2005-10-29[IPoIB] Drop RX packets when out of memoryRoland Dreier3-60/+85
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 Dreier1-2/+5
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>
2005-10-18[IPoIB] Rename ipoib_create_qp() -> ipoib_init_qp() and fix error cleanupRoland Dreier3-7/+8
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>
2005-09-29[IPoIB] Rename IPoIB's path_lookup() to avoid name clashesRoland Dreier1-2/+2
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 Dreier3-6/+7
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>
2005-09-19[PATCH] IPoIB: Fix SA client retransmission strategyHal Rosenstock1-3/+3
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>
2005-09-19[PATCH] IPoIB: fix module removal raceMichael S. Tsirkin1-0/+2
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. Tsirkin1-0/+2

2005-08-27[PATCH] IB: move include files to include/rdmaRoland Dreier4-7/+5
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>
2005-08-27[PATCH] IPoIB: Fix device removal raceMichael S. Tsirkin1-1/+1
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>
2005-08-27[PATCH] IPoIB: Set full membership bit in P_KeysRoland Dreier1-0/+12
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>

2005-04-17[PATCH] IPoIB: fix static rate calculationRoland Dreier2-8/+6
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.

2005-04-17[PATCH] IPoIB: set skb->mac.raw on receiveHal Rosenstock1-1/+1
Set skb->mac.raw on receive. This fixes crashes when this is dereferenced, for example by netfilter or when PF_PACKET is used.

2005-04-17Linux-2.6.12-rc2v2.6.12-rc2Linus Torvalds9-0/+3883
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!
