IB/iser: Don't defer connection failure notification to workqueue

2007-04-05T16:46:04Z

When a connection is terminated asynchronously from the iSCSI layer's perspective, iSER needs to notify the iSCSI layer that the connection has failed. This is done using a workqueue (switched to from the iSER tasklet context). Meanwhile, the connection object (that holds the work struct) is released. If the workqueue function wasn't called yet, it will be called later with a NULL pointer, which will crash the kernel. The context switch (tasklet to workqueue) is not required, and everything can be done from the iSER tasklet. This eliminates the NULL work struct bug (and simplifies the code).

IB/iser: Handle aborting a command after it is sent

2007-03-26T23:35:09Z

The SCSI midlayer may abort a command that was already sent. If the initiator is still trying to send the command (or data-out PDUs for that command), the QP may time out after the midlayer times out. Therefore, when aborting the command, iSER may still have references for the command's buffers. When sending these PDUs, the sends will complete with an error and their resources will be released then. Signed-off-by: Erez Zilber Signed-off-by: Roland Dreier

IB/iser: Return error code when PDUs may not be sent

2007-01-07T18:15:15Z

iSER limits the number of outstanding PDUs to send. When this threshold is reached, it should return an error code (-ENOBUFS) instead of setting the suspend_tx bit (which should be used only by libiscsi). Signed-off-by: Erez Zilber Signed-off-by: Roland Dreier

IB/iser: Use the new verbs DMA mapping functions

2006-12-12T22:31:00Z

Convert iSER to use the new verbs DMA mapping functions for kernel verbs consumers. Signed-off-by: Ralph Campbell Signed-off-by: Roland Dreier

IB/iser: Remove unused "write-only" variables

2006-12-12T19:50:20Z

Remove variables that are set but then never looked at in the iSER initiator. These cleanups came from David Binderman's list of "set but never used" warnings from icc. Signed-off-by: Roland Dreier

[PATCH] LOG2: Implement a general integer log2 facility in the kernel

2006-12-08T16:28:51Z

This facility provides three entry points: ilog2() Log base 2 of unsigned long ilog2_u32() Log base 2 of u32 ilog2_u64() Log base 2 of u64 These facilities can either be used inside functions on dynamic data: int do_something(long q) { ...; y = ilog2(x) ...; } Or can be used to statically initialise global variables with constant values: unsigned n = ilog2(27); When performing static initialisation, the compiler will report "error: initializer element is not constant" if asked to take a log of zero or of something not reducible to a constant. They treat negative numbers as unsigned. When not dealing with a constant, they fall back to using fls() which permits them to use arch-specific log calculation instructions - such as BSR on x86/x86_64 or SCAN on FRV - if available.
