Lee, Andre Guedes, Anders Roxell, Mao Wenan, Yue Haibing. ==================== Signed-off-by: David S. Miller <davem@davemloft.net>
2019-11-18bpf: Convert bpf_prog refcnt to atomic64_tAndrii Nakryiko1-6/+2
Similarly to bpf_map's refcnt/usercnt, convert bpf_prog's refcnt to atomic64 and remove artificial 32k limit. This allows to make bpf_prog's refcounting non-failing, simplifying logic of users of bpf_prog_add/bpf_prog_inc. Validated compilation by running allyesconfig kernel build.

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.")

2019-08-15qed: Add driver API for flashing the config attributes.Sudarsana Reddy Kalluru1-0/+68
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.

2019-08-02net/ethernet/qlogic/qed: force the string buffer NULL-terminatedWang Xiayang1-1/+1
strncpy() does not ensure NULL-termination when the input string size equals to the destination buffer size 30. The output string is passed to qed_int_deassertion_aeu_bit() which calls DP_INFO() and relies NULL-termination. Use strlcpy instead. The other conditional branch above strncpy() needs no fix as snprintf() ensures NULL-termination. This issue is identified by a Coccinelle script.

2019-07-09net: flow_offload: add flow_block_cb_setup_simple()Pablo Neira Ayuso1-20/+3
Most drivers do the same thing to set up the flow block callbacks, this patch adds a helper function to do this. This preparation patch reduces the number of changes to adapt the existing drivers to use the flow block callback API. This new helper function takes a flow block list per-driver, which is set to NULL until this driver list is used. This patch also introduces the flow_block_command and flow_block_binder_type enumerations, which are renamed to use FLOW_BLOCK_* in follow up patches. There are three definitions (aliases) in order to reduce the number of updates in this patch, which go away once drivers are fully adapted to use this flow block API.
