qed: Fix use after free in qed_chain_free

2020-05-02T06:49:01Z

commit 8063f761cd7c17fc1d0018728936e0c33a25388a upstream. 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.

qed*: Fix size of config attribute dump.

2019-09-11T14:15:23Z

Driver currently returns max-buf-size as size of the config attribute. This patch incorporates changes to read this value from MFW (if available) and provide it to the user. Also did a trivial clean up in this path. Fixes: d44a3ced7023 ("qede: Add support for reading the config id attributes.")

qed: Add driver API for flashing the config attributes.

2019-08-15T19:54:45Z

The patch adds driver interface for reading the config attributes from user provided buffer, and updates these values on nvm config flash partition. This is basically an expansion of our existing ethtool -f implementation. The management FW has exposed an additional method of configuring some of the nvram options, and this makes use of that. This implementation will come into use when newer FW files which contain configuration directives employing this API will be provided to ethtool -f.

qed*: Change dpi_addr to be denoted with __iomem

2019-07-25T18:03:26Z

Several casts were required around dpi_addr parameter in qed_rdma_if.h This is an address on the doorbell bar and should therefore be marked with __iomem.
