The macro was just making things harder to follow, and audit, so remove it and call debugfs_create_file() directly. Also, the macro did not need to warn about the call failing as no one should ever care about any debugfs functions failing. Signed-off-by:

As the comment block of nonseekable_open() describes, nonseekable_open() can never fail. Several places in kernel depend on this behavior. Therefore, simplify the umad module to depend on this basic kernel functionality. Signed-off-by:

ib_umad_init_port_dev() holds the reference of a ib_umad_device instance. ib_umad_device contains standard core device and cdev. cdev holds the reference of its parent core device. file ops holds the reference to cdev using core kernel. Therefore, there is no need to hold additional reference while opening umad related char devices. While at it, add comments to bring clarity on releasing references to ib_umd_device. Signed-off-by:

Two flow specifications can set the ip protocol field in the flow table entry: 1) IB_FLOW_SPEC_TCP/UDP/GRE - set the ip protocol accordingly. 2) IB_FLOW_SPEC_IPV4/6 - has ip_protocol field for users who want to receive specific L4 packets. We need to avoid overriding of the ip_protocol with zeros, in case that the user first put the L4 specification and only then the L3.

AEQ overflow will be reported by hardware when too many asynchronous events occurred but not be handled in time. Normally, AEQ overflow error is not easy to occur. Once happened, we have to do physical function reset to recover. PF reset is implemented in two steps. Firstly, set reset level with ae_dev->ops->set_default_reset_request. Secondly, run reset with ae_dev->ops->reset_event. Signed-off-by:

ib_dma_map_sg() augments the SGL into a 'dma mapped SGL'. This process may change the number of entries and the lengths of each entry. Code that touches dma_address is iterating over the 'dma mapped SGL' and must use dma_nents which returned from ib_dma_map_sg(). ib_sg_to_pages() and ib_map_mr_sg() are using dma_address so they must use dma_nents.

If cma_acquire_dev_by_src_ip() returns error in addr_handler(), the device state changes back to RDMA_CM_ADDR_BOUND but the resolved source IP address is still left. After that, if rdma_destroy_id() is called after rdma_listen(), the device is freed without removed from listen_any_list in cma_cancel_operation(). Revert to the previous IP address if acquiring device fails. Reported-by: syzbot+f3ce716af730c8f96637@syzkaller.appspotmail.com Signed-off-by:

This is from static analysis not from testing. Depending on the value of rcfw->cmdq_depth, then this might not cause an issue at runtime. The BITS_TO_LONGS() macro tells us how many longs it take to hold a bitmap. In other words, it divides by the number if bits per long and rounds up. Then we want to take that number and multiple by sizeof(long) to get the number of bytes to allocate. The code here does the multiplication first so the rounding up is done in the wrong place. So imagine we want to allocate 1 bit, then "(1 * 8) / 64 = 1" when we round up. But it should be "(1 / 64) * 8 = 8". In other words, because of the rounding difference we might allocate up to "sizeof(long) - 1" bytes fewer than intended. Fixes: 1ac5a404 ("RDMA/bnxt_re: Add bnxt_re RoCE driver") Signed-off-by:

Most provider routines are callback routines which ib core invokes. _callback suffix doesn't convey information about when such callback is invoked. Therefore, rename port_callback to init_port. Additionally, store the init_port function pointer in ib_device_ops, so that it can be accessed in subsequent patches when binding rdma device to net namespace. Signed-off-by:
