2020-02-18qede: Fix race between rdma destroy workqueue and link change eventMichal Kalderon2-1/+30
If an event is added while the rdma workqueue is being destroyed it could lead to several races, list corruption, null pointer dereference during queue_work or init_queue. This fixes the race between the two flows which can occur during shutdown. A kref object and a completion object are added to the rdma_dev structure, these are initialized before the workqueue is created. The refcnt is used to indicate work is being added to the workqueue and ensures the cleanup flow won't start while we're in the middle of adding the event. Once the work is added, the refcnt is decreased and the cleanup flow is safe to run.

2020-01-27qed: FW 8.42.2.0 debug featuresMichal Kalderon5-2536/+1519
Add to debug dump more information on the platform it was collected from (pci func, path id). Provide human readable reg fifo erros. Removed static debug arrays from HSI Functions, and move them to the hwfn. Some structures were slightly changed (removing reserved chip id for example) which lead to many long initializations being modified with one parameter less during initialization. This leads to some long diffs that don't really change anything.

2020-01-27qed: rt init valid initialization changedMichal Kalderon3-21/+6
The QM phase init tool can be invoked multiple times during the driver lifetime. Part of the init comes from the runtime array. The logic for setting the values did not init all values, basically assuming the runtime array was all zeroes. But if it was invoked multiple times, nobody was zeroing it after the first time. In this change we zero the runtime array right after using it.

2020-01-27qed: FW 8.42.2.0 Additional ll2 typeMichal Kalderon8-34/+212
LL2 queues were a limited resource due to FW constraints. This FW introduced a new resource which is a context based ll2 queue (memory on host). The additional ll2 queues are required for RDMA SRIOV. The code refers to the previous ll2 queues as ram-based or legacy, and the new queues as ctx-based. This change decreased the "legacy" ram-based queues therefore the first ll2 queue used for iWARP was converted to the ctx-based ll2 queue. This feature also exposed a bug in the DIRECT_REG_WR64 macro implementation which didn't have an effect in other use cases.

2020-01-27qed: Use dmae to write to widebus registers in fw_funcsMichal Kalderon7-91/+142
There are several wide-bus registers written to by the fw_funcs that require using the dmae for atomicity. Therefore using the dmae channel functionality was added to the fw_funcs file, since the code is very similar to the previously used code, the structures used were moved to qed_hsi. Due to FW conventions, the names of the flags in the struct changed. Since this required slight modification in the places that set the flags the code was modified to use GET/SET FIELD macros.

2019-12-17net: qlogic: Fix error paths in ql_alloc_large_buffers()Ben Hutchings1-4/+4
ql_alloc_large_buffers() has the usual RX buffer allocation loop where it allocates skbs and maps them for DMA. It also treats failure as a fatal error. There are (at least) three bugs in the error paths: 1. ql_free_large_buffers() assumes that the lrg_buf[] entry for the first buffer that couldn't be allocated will have .skb == NULL. But the qla_buf[] array is not zero-initialised. 2. ql_free_large_buffers() DMA-unmaps all skbs in lrg_buf[]. This is incorrect for the last allocated skb, if DMA mapping failed. 3. Commit 1acb8f2a7a9f ("net: qlogic: Fix memory leak in ql_alloc_large_buffers") added a direct call to dev_kfree_skb_any() after the skb is recorded in lrg_buf[], so ql_free_large_buffers() will double-free it. The bugs are somewhat inter-twined, so fix them all at once: * Clear each entry in qla_buf[] before attempting to allocate an skb for it. This goes half-way to fixing bug 1. * Set the .skb field only after the skb is DMA-mapped. This fixes the rest. Fixes: 1357bfcf7106 ("qla3xxx: Dynamically size the rx buffer queue ...")

Similarly to bpf_map's refcnt/usercnt, convert bpf_prog's refcnt to atomic64 and remove artificial 32k limit.

2019-11-08qede: fix NULL pointer deref in __qede_remove()Manish Chopra1-2/+10
While rebooting the system with SR-IOV vfs enabled leads to below crash due to recurrence of __qede_remove() on the VF devices (first from .shutdown() flow of the VF itself and another from PF's .shutdown() flow executing pci_disable_sriov()) This patch adds a safeguard in __qede_remove() flow to fix this, so that driver doesn't attempt to remove "already removed" devices.

2019-10-30qed: Optimize execution time for nvm attributes configuration.Sudarsana Reddy Kalluru1-6/+21
Current implementation for nvm_attr configuration instructs the management FW to load/unload the nvm-cfg image for each user-provided attribute in the input file. This consumes lot of cycles even for few tens of attributes. This patch updates the implementation to perform load/commit of the config for every 50 attributes. After loading the nvm-image, MFW expects that config should be committed in a predefined timer value (5 sec), hence it's not possible to write large number of attributes in a single load/commit window. Hence performing the commits in chunks. Fixes: 0dabbe1bb3a4 ("qed: Add driver API for flashing the config attributes.")
