With commit eea40b8f ("infiniband: call ipv6 route lookup via the stub interface"), if the route lookup fails due to ipv6 being disabled, the dst variable is left untouched, and the following dst_release() may access uninitialized memory. Since ipv6_dst_lookup() always sets dst to NULL in case of lookup failure with ipv6 enabled, fix the above just returning the error code if the lookup fails.

When importing the patch 57520751 (IB/SA: Add OPA path record type), a new header file should have been added to the repo as part of the patch. However, as the patch didn't apply cleanly using git am, I instead used patch manually, and followed that up with git add -u, which misses new files. This adds the new file back in.

Add port_xmit_wait to the error counters read by mlx5_ib_process_mad to ensure sysfs port counter provides correct value for PortXmitWait. Otherwise the sysfs port_xmit_wait file always contains zero. The previous MAD_IFC implementation populated this counter, but it was removed during the migration to PPCNT for error counters (32-bit only). Signed-off-by:

In write to debugfs file 'resource_stats' the local buffer 'tmp_str' is written at index 'count-1' where 'count' is the size of the write, so potentially 0. This patch filters odd values for the write size/position to avoid this type of problem. Signed-off-by:

The last two actual parameters when calling id_map_find_by_sl_id() from id_map_get() are swapped. However, the same formal parameters to id_map_get() have them swapped as well, inverting the effect of the first error. This commit improves readability, but makes no functional change to the code.

When reading a RDMA WRITE FIRST packet we copy the DMA length from the RDMA header into the qp->resp.resid variable for later use. Later in check_rkey() we clamp it to the MTU if the packet is an RDMA WRITE packet and has a residual length bigger than the MTU. Later in write_data_in() we subtract the payload of the packet from the residual length. If the packet happens to have a payload of exactly the MTU size we end up with a residual length of 0 despite the packet not being the last in the conversation. When the next packet in the conversation arrives, we don't have any residual length left and thus set the QP into an error state. This broke NVMe over Fabrics functionality over rdma_rxe.ko The patch was verified using the following test. # echo eth0 > /sys/module/rdma_rxe/parameters/add # nvme connect -t rdma -a 192.168.155.101 -s 1023 -n nvmf-test # mkfs.xfs -fK /dev/nvme0n1 meta-data=/dev/nvme0n1 isize=256 agcount=4, agsize=65536 blks = sectsz=4096 attr=2, projid32bit=1 = crc=0 finobt=0, sparse=0 data = bsize=4096 blocks=262144, imaxpct=25 = sunit=0 swidth=0 blks naming =version 2 bsize=4096 ascii-ci=0 ftype=1 log =internal log bsize=4096 blocks=2560, version=2 = sectsz=4096 sunit=1 blks, lazy-count=1 realtime =none extsz=4096 blocks=0, rtextents=0 # mount /dev/nvme0n1 /tmp/ [ 148.923263] XFS (nvme0n1): Mounting V4 Filesystem [ 148.961196] XFS (nvme0n1): Ending clean mount # dd if=/dev/urandom of=test.bin bs=1M count=128 128+0 records in 128+0 records out 134217728 bytes (134 MB, 128 MiB) copied, 0.437991 s, 306 MB/s # sha256sum test.bin cde42941f045efa8c4f0f157ab6f29741753cdd8d1cff93a6b03649d83c4129a test.bin # cp test.bin /tmp/ sha256sum /tmp/test.bin cde42941f045efa8c4f0f157ab6f29741753cdd8d1cff93a6b03649d83c4129a /tmp/test.bin Signed-off-by:Johannes Thumshirn <jthumshirn@suse.de> Cc: Hannes Reinecke <hare@suse.de> Cc: Sagi Grimberg <sagi@grimberg.me> Cc: Max Gurtovoy <maxg@mellanox.com> Acked-by:

Callers such as IPoIB and CM can query the SA to get the classportinfo information. Apart from making the caller code much simpler, this change puts the onus on the SA to query and maintain classportinfo much like how it maitains the address handle to the SM. Reviewed-by:
