2012-09-07target: support zero-size allocation lengths in transport_kmap_data_sgPaolo Bonzini
In order to support zero-size allocation lengths, do not assert that we have a scatterlist until after checking cmd->data_length. But once we do this, we can have two cases of transport_kmap_data_sg returning NULL: a zero-size allocation length, or an out-of-memory condition. Report the latter using sense codes, so that the SCSI command that triggered it will fail. Signed-off-by: Paolo Bonzini <pbonzini@redhat.com> Signed-off-by: Nicholas Bellinger <nab@linux-iscsi.org>

2012-09-07target: fail REPORT LUNS with less than 16 bytes of payloadPaolo Bonzini
SPC says: "The ALLOCATION LENGTH field is defined in 4.3.5.6. The allocation length should be at least 16. Device servers compliant with SPC return CHECK CONDITION status, with the sense key set to ILLEGAL REQUEST, and the additional sense code set to INVALID FIELD IN CDB when the allocation length is less than 16 bytes". Testcase: sg_raw -r8 /dev/sdb a0 00 00 00 00 00 00 00 00 08 00 00 should fail with ILLEGAL REQUEST / INVALID FIELD IN CDB sense does not fail without the patch fails correctly with the patch Signed-off-by: Paolo Bonzini <pbonzini@redhat.com> Signed-off-by: Nicholas Bellinger <nab@linux-iscsi.org>
2012-09-07target: report too-small parameter lists everywherePaolo Bonzini
Several places were not checking that the parameter list length was large enough, and thus accessing invalid memory. Zero-length parameter lists are just a special case of this. Signed-off-by: Paolo Bonzini <pbonzini@redhat.com> Signed-off-by: Nicholas Bellinger <nab@linux-iscsi.org>
2012-09-07target: go through normal processing for zero-length PSCSI commandsPaolo Bonzini
Right now, commands with a zero-size payload are skipped completely. This is wrong; such commands should be passed down to the device and processed normally. For physical backends, this ignores completely things such as START STOP UNIT. For virtual backends, we have a hack in place to clear a unit attention state on a zero-size REQUEST SENSE, but we still do not report errors properly on zero-length commands---out-of-bounds 0-block reads and writes, too small parameter list lengths, etc. This patch fixes this for PSCSI. Uses of transport_kmap_data_sg are guarded with a check for non-zero cmd->data_length; for all other commands a zero length is handled properly in pscsi_execute_cmd. The sole exception will be for now REPORT LUNS, which is handled through the normal SPC emulation.

2012-09-07net/mlx4_core: Looking for promiscuous entries on the correct portAviad Yehezkel
The search for promisc entries was always done on the first port, While the addition is done on the correct port. This lead to resource leackage of promisc entries on the second port and brought to a state where we could no longer enter to promiscuous mode after enough iterations of "ifconfig promisc" on the second port.

2012-09-07SUNRPC: Fix a UDP transport regressionTrond Myklebust
Commit 43cedbf0e8dfb9c5610eb7985d5f21263e313802 (SUNRPC: Ensure that we grab the XPRT_LOCK before calling xprt_alloc_slot) is causing hangs in the case of NFS over UDP mounts. Since neither the UDP or the RDMA transport mechanism use dynamic slot allocation, we can skip grabbing the socket lock for those transports. Add a new rpc_xprt_op to allow switching between the TCP and UDP/RDMA case. Note that the NFSv4.1 back channel assigns the slot directly through rpc_run_bc_task, so we can ignore that case.
