2019-06-25RDMA/netlink: Audit policy settings for netlink attributesDoug Ledford
For all string attributes for which we don't currently accept the element as input, we only use it as output, set the string length to RDMA_NLDEV_ATTR_EMPTY_STRING which is defined as 1. That way we will only accept a null string for that element. This will prevent someone from writing a new input routine that uses the element without also updating the policy to have a valid value. Also while there, make sure the existing entries that are valid have the correct policy, if not, correct the policy. Remove unnecessary checks for nla_strlcpy() overflow once the policy has been set correctly. Signed-off-by: Doug Ledford <dledford@redhat.com> Signed-off-by: Jason Gunthorpe <jgg@mellanox.com>

2019-06-24RDMA/rw: Use IB_WR_REG_MR_INTEGRITY for PI handoverIsrael Rukshin
Replace the old signature handover API with the new one. The new API simplifes PI handover code complexity for ULPs and improve performance. For RW API it will reduce the maximum number of work requests per task and the need of dealing with multiple MRs (and their registrations and invalidations) per task. All the mappings and registration of the data and the protection buffers is done by the LLD using a single WR and a special MR type (IB_MR_TYPE_INTEGRITY) for the PI handover operation. The setup of the tested benchmark (using iSER ULP): - 2 servers with 24 cores (1 initiator and 1 target) - ConnectX-4/ConnectX-5 adapters - 24 target sessions with 1 LUN each - ramdisk backstore - PI active Performance results running fio (24 jobs, 128 iodepth) using write_generate=1 and read_verify=1 (w/w.o patch): bs IOPS(read) IOPS(write) ---- ---------- ---------- 512 1243.3K/1182.3K 1725.1K/1680.2K 4k 571233/528835 743293/748259 32k 72388/71086 71789/93573 Using write_generate=0 and read_verify=0 (w/w.o patch): bs IOPS(read) IOPS(write) ---- ---------- ---------- 512 1572.1K/1427.2K 1823.5K/1724.3K 4k 921992/916194 753772/768267 32k 75052/73960 73180/95484 There is a performance degradation when writing big block sizes.

2019-06-24RDMA/mlx5: Introduce and implement new IB_WR_REG_MR_INTEGRITY work requestMax Gurtovoy
This new WR will be used to perform PI (protection information) handover using the new API. Using the new API, the user will post a single WR that will internally perform all the needed actions to complete PI operation. This new WR will use a memory region that was allocated as IB_MR_TYPE_INTEGRITY and was mapped using ib_map_mr_sg_pi to perform the registration. In the old API, in order to perform a signature handover operation, each ULP should perform the following: 1. Map and register the data buffers. 2. Map and register the protection buffers. 3. Post a special reg WR to configure the signature handover operation layout. 4. Invalidate the signature memory key. 5. Invalidate protection buffers memory key. 6. Invalidate data buffers memory key. In the new API, the mapping of both data and protection buffers is performed using a single call to ib_map_mr_sg_pi function. Also the registration of the buffers and the configuration of the signature operation layout is done by a single new work request called IB_WR_REG_MR_INTEGRITY. This patch implements this operation for mlx5 devices that are capable to offload data integrity generation/validation while performing the actual buffer transfer. This patch will not remove the old signature API that is used by the iSER initiator and target drivers. This will be done in the future. In the internal implementation, for each IB_WR_REG_MR_INTEGRITY work request, we are using a single UMR operation to register both data and protection buffers using KLM's. Afterwards, another UMR operation will describe the strided block format. These will be followed by 2 SET_PSV operations to set the memory/wire domains initial signature parameters passed by the user. In the end of the whole transaction, only the signature memory key (the one that exposed for the RDMA operation) will be invalidated.

PI offload (protection information) is a feature that each RDMA provider can implement differently. Thus, introduce new device attribute to define the maximal length of the page list for PI fast registration operation. For example, mlx5 driver uses a single internal MR to map both data and protection SGL's, so it's equal to max_fast_reg_page_list_len / 2.

2019-05-18panic: add an option to replay all the printk message in bufferFeng Tang
Currently on panic, kernel will lower the loglevel and print out pending printk msg only with console_flush_on_panic(). Add an option for users to configure the "panic_print" to replay all dmesg in buffer, some of which they may have never seen due to the loglevel setting, which will help panic debugging .
