ethtool: netlink: Add missing ethnl_ops_begin/complete

2024-01-18T12:21:06Z

Accessing an ethernet device that is powered off or clock gated might cause the CPU to hang. Add ethnl_ops_begin/complete in ethnl_set_features() to protect against this.

net: ethtool: Fix symmetric-xor RSS RX flow hash check

2024-01-03T00:19:18Z

Commit 13e59344fb9d ("net: ethtool: add support for symmetric-xor RSS hash") adds a check to the ethtool set_rxnfc operation, which checks the RX flow hash if the flag RXH_XFRM_SYM_XOR is set. This flag is introduced with the same commit. It calls the ethtool get_rxfh operation to get the RX flow hash data. If get_rxfh is not supported, then EOPNOTSUPP is returned. There are driver like tsnep, macb, asp2, genet, gianfar, mtk, ... which support the ethtool operation set_rxnfc but not get_rxfh. This results in EOPNOTSUPP returned by ethtool_set_rxnfc() without actually calling the ethtool operation set_rxnfc. Thus, set_rxnfc got broken for all these drivers. Check RX flow hash in ethtool_set_rxnfc() only if driver supports RX flow hash.

net: ethtool: add a NO_CHANGE uAPI for new RXFH's input_xfrm

Add a NO_CHANGE uAPI value for the new RXFH/RSS input_xfrm uAPI field. This needed so that user-space can set other RSS values (hkey or indir table) without affecting input_xfrm.
