scsi: qla4xxx needs libiscsi.o

2011-10-03T18:41:10Z

commit 3538a001ea7db13fa1be2966b71f69d808acff01 upstream. qla4xxx driver needs to be linked with libiscsi.o to fix build errors. This happens when no other drivers that use libiscsi.o are enabled.

libsas: fix failure to revalidate domain for anything but the first expander child.

2011-10-03T18:41:10Z

commit 24926dadc41cc566e974022b0e66231b82c6375f upstream. In an enclosure model where there are chaining expanders to a large body of storage, it was discovered that libsas, responding to a broadcast event change, would only revalidate the domain of first child expander in the list. The issue is that the pointer value to the discovered source device was used to break out of the loop, rather than the content of the pointer. This still remains non-compliant as the revalidate domain code is supposed to loop through all child expanders, and not stop at the first one it finds that reports a change count. However, the design of this routine does not allow multiple device discoveries and that would be a more complicated set of patches reserved for another day. We are fixing the glaring bug rather than refactoring the code. Signed-off-by: Mark Salyzyn Signed-off-by: James Bottomley Signed-off-by: Greg Kroah-Hartman

3w-9xxx: fix iommu_iova leak

2011-10-03T18:41:09Z

commit 96067723e46b0dd24ae7b934085ab4eff4d26a1b upstream. Following reports on the list, it looks like the 3e-9xxx driver will leak dma mappings every time we get a transient queueing error back from the card. This is because it maps the sg list in the routine that sends the command, but doesn't unmap again in the transient failure path (even though the command is sent back to the block layer). Fix by unmapping before returning the status. Reported-by: Chris Boot Tested-by: Chris Boot Acked-by: Adam Radford Signed-off-by: James Bottomley Signed-off-by: Greg Kroah-Hartman

bnx2fc: scsi_dma_unmap() not invoked on IO completions

bnx2fc: Fix kernel panic when deleting NPIV ports

2011-10-03T18:41:05Z

commit d36b3279e157641c345b12eddb3db78fb42da80f upstream. Deleting NPIV port causes a kernel panic when the NPIV port is in the same zone as the physical port and shares the same LUN. This happens due to the fact that vport destroy and unsolicited ELS are scheduled to run on the same workqueue, and vport destroy destroys the lport and the unsolicited ELS tries to access the invalid lport. This patch fixes this issue by maintaining a list of valid lports and verifying if the lport is valid or not before accessing it.
