IB/srp: Check match_strdup() return

2007-01-23T01:03:54Z

Checks if the kmalloc in match_strdup() was successful, and bail out on looking at the token if it failed. Signed-off-by: Ishai Rabinovitz 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/srp: Fix FMR mapping for 32-bit kernels and addresses above 4G

2006-12-15T22:01:49Z

struct srp_device.fmr_page_mask was unsigned long, which means that the top part of addresses above 4G was being chopped off on 32-bit architectures. Of course nothing good happens when data from SRP targets is DMAed to the wrong place. Fix this by changing fmr_page_mask to u64, to match the addresses actually used by IB devices. Thanks to Brian Cain and David McMillen for help diagnosing the bug and testing the fix. Signed-off-by: Roland Dreier

IPoIB: Make sure struct ipoib_neigh.queue is always initialized

2006-12-12T22:48:18Z

Move the initialization of ipoib_neigh's skb_queue into ipoib_neigh_alloc(), since commit 2745b5b7 ("IPoIB: Fix skb leak when freeing neighbour") will make iterate over the skb_queue to free any packets left over when freeing the ipoib_neigh structure. This fixes a crash when freeing ipoib_neigh structures allocated in ipoib_mcast_send(), which otherwise don't have their skb_queue initialized. Signed-off-by: Roland Dreier

IB/iser: Use the new verbs DMA mapping functions

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.
