2020-05-14net: qed: invoke err notify on critical areasIgor Russkikh
In a number of critical places not only debug trace should be printed, but the appropriate hw error condition should be raised and error handling/recovery should start. Introduce our new qed_hw_err_notify invocation in these places to record and indicate critical error conditions in hardware.

2020-05-14net: qede: add hw err scheduled handlerIgor Russkikh
qede (ethernet level driver) registers a callback handler. This handler maintains eth dev state flags/bits to track error processing. It implements in place processing part for nonsleeping context (WARN_ON trigger), and a deferred (delayed work) part which triggers recovery process for recoverable errors. In later patches this atomic handler will come with more meat. We introduce err_flags on ethdevice structure, its being used to record error handling properties.

2020-05-11net: qed: Disable SRIOV functionality inside kdump kernelBhupesh Sharma
Since we have kdump kernel(s) running under severe memory constraint it makes sense to disable the qed SRIOV functionality when running the kdump kernel as kdump configurations on several distributions don't support SRIOV targets for saving the vmcore (see [1] for example). Currently the qed SRIOV functionality ends up consuming memory in the kdump kernel, when we don't really use the same. An example log seen in the kdump kernel with the SRIOV functionality enabled can be seen below (obtained via memstrack tool, see [2]): dracut-pre-pivot[676]: ======== Report format module_summary: ======== dracut-pre-pivot[676]: Module qed using 149.6MB (2394 pages), peak allocation 149.6MB (2394 pages) This patch disables the SRIOV functionality inside kdump kernel and with the same applied the memory consumption goes down: dracut-pre-pivot[671]: ======== Report format module_summary: ======== dracut-pre-pivot[671]: Module qed using 124.6MB (1993 pages), peak allocation 124.7MB (1995 pages) [1]. https://access.redhat.com/documentation/en-us/red_hat_enterprise_linux/8/html/managing_monitoring_and_updating_the_kernel/installing-and-configuring-kdump_managing-monitoring-and-updating-the-kernel#supported-kdump-targets_supported-kdump-configurations-and-targets [2].

2020-05-11net: qed*: Reduce RX and TX default ring count when running inside kdump kernelBhupesh Sharma
Normally kdump kernel(s) run under severe memory constraint with the basic idea being to save the crashdump vmcore reliably when the primary kernel panics/hangs. Currently the qed* ethernet driver ends up consuming a lot of memory in the kdump kernel, leading to kdump kernel panic when one tries to save the vmcore via ssh/nfs (thus utilizing the services of the underlying qed* network interfaces). An example OOM message log seen in the kdump kernel can be seen here [1], with crashkernel size reservation of 512M. Using tools like memstrack (see [2]), we can track the modules taking up the bulk of memory in the kdump kernel and organize the memory usage output as per 'highest allocator first'. An example log for the OOM case indicates that the qed* modules end up allocating approximately 216M memory, which is a large part of the total crashkernel size: dracut-pre-pivot[676]: ======== Report format module_summary: ======== dracut-pre-pivot[676]: Module qed using 149.6MB (2394 pages), peak allocation 149.6MB (2394 pages) dracut-pre-pivot[676]: Module qede using 65.3MB (1045 pages), peak allocation 65.3MB (1045 pages) This patch reduces the default RX and TX ring count from 1024 to 64 when running inside kdump kernel, which leads to a significant memory saving. An example log with the patch applied shows the reduced memory allocation in the kdump kernel: dracut-pre-pivot[674]: ======== Report format module_summary: ======== dracut-pre-pivot[674]: Module qed using 141.8MB (2268 pages), peak allocation 141.8MB (2268 pages) <..snip..> [dracut-pre-pivot[674]: Module qede using 4.8MB (76 pages), peak allocation 4.9MB (78 pages) Tested crashdump vmcore save via ssh/nfs protocol using underlying qed* network interface after applying this patch.

2020-03-30qed: Fix use after free in qed_chain_freeYuval Basson
The qed_chain data structure was modified in commit 1a4a69751f4d ("qed: Chain support for external PBL") to support receiving an external pbl (due to iWARP FW requirements). The pages pointed to by the pbl are allocated in qed_chain_alloc and their virtual address are stored in an virtual addresses array to enable accessing and freeing the data. The physical addresses however weren't stored and were accessed directly from the external-pbl during free. Destroy-qp flow, leads to freeing the external pbl before the chain is freed, when the chain is freed it tries accessing the already freed external pbl, leading to a use-after-free. Therefore we need to store the physical addresses in additional to the virtual addresses in a new data structure.

2020-02-26qlogic: Replace zero-length array with flexible-array memberGustavo A. R. Silva
The current codebase makes use of the zero-length array language extension to the C90 standard, but the preferred mechanism to declare variable-length types such as these ones is a flexible array member[1][2], introduced in C99: struct foo { int stuff; struct boo array[]; }; By making use of the mechanism above, we will get a compiler warning in case the flexible array does not occur last in the structure, which will help us prevent some kind of undefined behavior bugs from being inadvertently introduced[3] to the codebase from now on. Also, notice that, dynamic memory allocations won't be affected by this change: "Flexible array members have incomplete type, and so the sizeof operator may not be applied. As a quirk of the original implementation of zero-length arrays, sizeof evaluates to zero."[1] This issue was detected with the help of Coccinelle.

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.

This change decreased the "legacy" ram-based queues therefore the first ll2 queue used for iWARP was converted to the ctx-based ll2 queue.

2020-01-27qed: FW 8.42.2.0 Queue Manager changesMichal Kalderon
This patch contains changes in initialization and usage of the QM blocks. Instead of setting a rate limiter per vport the rate limiters are now a global resource and set independentaly. The patch also contains a field name change: vport_wfq which is part of vport_params was renamed to wfq as the vport prefix is redundant.

Driver while collecting firmware dump takes longer time to collect/process some of the firmware dump entries/memories. Bigger capture masks makes it worse as it results in larger amount of data being collected and results in CPU soft lockup. Place cond_resched() in some of the driver flows that are expectedly time consuming to relinquish the CPU to avoid CPU soft lockup panic.

2019-12-17net: qlogic: Fix error paths in ql_alloc_large_buffers()Ben Hutchings
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 ...")
