| * IB/mad: include GID/class when matching receivesJack Morgenstein2006-03-30
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Received responses are currently matched against sent requests based on TID only. According to the spec, responses should match based on the combination of TID, management class, and requester LID/GID. Without the additional qualification, an agent that is responding to two requests, both of which have the same TID, can match RMPP ACKs with the incorrect transaction. This problem can occur on the SM node when responding to SA queries.

| * IB/mthca: Fix section mismatch problemsRoland Dreier2006-03-29
| | | | | | | | | | | | | | | | | | Quite a few cleanup functions in mthca were marked as __devexit. However, they could also be called from error paths during initialization, so they cannot be marked that way. Just delete all of the incorrect annotations.

| * IPoIB: Fix oops with raw socketsRoland Dreier2006-03-29
| | | | | | | | | | | | | | | | | | | | ipoib_hard_header() needs to handle the case that daddr is NULL. This can happen when packets are injected via a raw socket, and IPoIB shouldn't oops in this case. Reported by Anton Blanchard <anton@samba.org> Signed-off-by: Roland Dreier <rolandd@cisco.com>
| * IB/mthca: Fix check of size in SRQ creationJack Morgenstein2006-03-29
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The previous patch for Tavor broke MemFree logic. The driver should perform limit check only for Tavor. For MemFree, the check is incorrect, since ds (WQE stride) is always a power-of-2 (although the max_desc_size may not be). In Tavor, however, WQE stride and desc_size are the same, and are not necessarily power-of-2. The check was really for the WQE stride (and it Tavor, we use max_desc_size for the stride).

| * IB/srp: Fix unmapping of fake scatterlistRoland Dreier2006-03-29
| | | | | | | | | | | | | | | | | | The recently merged patch to create a fake scatterlist for non-SG SCSI commands had a bug: the driver ended up doing dma_unmap_sg() on a scatterlist scmnd->request_buffer rather than the fake scatter list it created. Fix this so that the driver unmaps the same thing it maps. Signed-off-by: Roland Dreier <rolandd@cisco.com>

Fixed. (1) The DEV_IRQ interrupt cause bit happens spuriously during EDMA operation, and was not being ignored by the driver. This led to various "drive busy" errors being reported, with associated unpredictable behaviour. Fixed. (2) If a SATA or PCI interrupt was received with no outstanding command, the interrupt handler still attempted to invoke ata_qc_complete(), triggering assert()/BUG_ON() behaviour elsewhere in libata. Fixed. The driver still has issues with confusion after error-recovery, but should now be reliable in the absence of drive errors. I will be looking more into the error-handling bugs next.

The simplex filter deals with 'to spec' simplex DMA systems found in older chips. The cable filter avoids duplicating the same rules in each chip driver with PATA. Finally the mode filter is neccessary because drive/chip combinations have errata that forbid certain modes with some drives or types of ATA object. Drive speed setup remains per channel for now and the filters now use the framework Tejun put into place which cleans them up a lot from the older libata-pata patches.

Simplex status is recorded but not acted upon in this change, this isn't a problem with the current drivers as none of them are for simplex hardware. A following diff will deal with that. The flags in the probe structure remain ->host_set_flags although Jeff asked me to rename them, simply because the rename would break the usual Linux rules that old code should break when there are changes. not compile and run and then blow up/eat your computer/etc. Renaming this later is a trivial exercise once a better name is chosen.

What appears to be a problem coming from flush_tlb_range(), which currently unconditionally calls platform_global_tlb_purge(). For some of the numa machines in existence today, this function is mapped into ia64_global_tlb_purge(), which holds ptcg_lock spin lock while executing ptc.ga instruction. Here is a patch that attempt to avoid global tlb purge whenever possible. It will use local tlb purge as much as possible. Though the conditions to use local tlb purge is pretty restrictive. One of the side effect of having flush tlb range instruction on ia64 is that kernel don't get a chance to clear out cpu_vm_mask. On ia64, this mask is sticky and it will accumulate if process bounces around. Thus diminishing the possible use of ptc.l. Thoughts?

* | | | | | | [PATCH] Introduce sys_splice() system callJens Axboe2006-03-30
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This adds support for the sys_splice system call. Using a pipe as a transport, it can connect to files or sockets (latter as output only). From the splice.c comments: "splice": joining two ropes together by interweaving their strands. This is the "extended pipe" functionality, where a pipe is used as an arbitrary in-memory buffer. Think of a pipe as a small kernel buffer that you can use to transfer data from one end to the other. The traditional unix read/write is extended with a "splice()" operation that transfers data buffers to or from a pipe buffer. Named by Larry McVoy, original implementation from Linus, extended by Jens to support splicing to files and fixing the initial implementation bugs.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | gcc4 doesn't like us declaring a static function inside another function. We can do away with this construct altogether and use BUILD_BUG_ON() instead (idea from Andi Kleen.)

A recent patch (in the last 3 months) changed how the code worked, but did not change the comments. Side comment: the new behaviour is good; I've got a pcnet32 card which powers up with garbage in the CSR's, and a good MAC addr in the PROM.
