2022-03-14RDMA/irdma: Prevent some integer underflowsDan Carpenter1-5/+5
My static checker complains that: drivers/infiniband/hw/irdma/ctrl.c:3605 irdma_sc_ceq_init() warn: can subtract underflow 'info->dev->hmc_fpm_misc.max_ceqs'? It appears that "info->dev->hmc_fpm_misc.max_ceqs" comes from the firmware in irdma_sc_parse_fpm_query_buf() so, yes, there is a chance that it could be zero. Even if we trust the firmware, it's easy enough to change the condition just as a hardenning measure.

This is not allowed during spin_unlock_bh() causing programs that use rdmacm to fail. This patch reverts the changes to locks that had this problem or got dragged into the same mess. After this patch blktests/check -q srp now runs correctly.

2022-02-11RDMA/hfi: Replace cpumask_weight with cpumask_empty where appropriateYury Norov1-2/+2
drivers/infiniband/hw/hfi1/affinity.c code calls cpumask_weight() to check if any bit of a given cpumask is set. We can do it more efficiently with cpumask_empty() because cpumask_empty() stops traversing the cpumask as soon as it finds first set bit, while cpumask_weight() counts all bits unconditionally.

2022-02-03ice: add support for DSCP QoS for IDCDave Ertman2-0/+9
The ice driver provides QoS information to auxiliary drivers through the exported function ice_get_qos_params. This function doesn't currently support L3 DSCP QoS. Add the necessary defines, structure elements and code to support DSCP QoS through the IIDC functions.
