2020-10-06ethtool: link up ethnl_header_policy as a nested policyJakub Kicinski1-2/+4
To get the most out of parsing by the core, and to allow dumping full policies we need to specify which policy applies to nested attrs. For headers it's ethnl_header_policy. $ sed -i 's@\(ETHTOOL_A_.*HEADER\].*=\) { .type = NLA_NESTED },@\1\n\t\tNLA_POLICY_NESTED(ethnl_header_policy),@' net/ethtool/* Signed-off-by: Jakub Kicinski <kuba@kernel.org> Signed-off-by: David S.

2020-10-06ethtool: trim policy tablesJakub Kicinski1-6/+2
Since ethtool uses strict attribute validation there's no need to initialize all attributes in policy tables. 0 is NLA_UNSPEC which is going to be rejected. Remove the NLA_REJECTs. Similarly attributes above maxattrs are rejected, so there's no need to always size the policy tables to ETHTOOL_A_..._MAX. v2: - new patch Suggested-by: Johannes Berg <johannes@sipsolutions.net> Signed-off-by: Jakub Kicinski <kuba@kernel.org> Signed-off-by: David S.

2020-10-06ethtool: wire up set policies to opsJakub Kicinski1-7/+2
Similarly to get commands wire up the policies of set commands to get parsing by the core and policy dumps. Signed-off-by: Jakub Kicinski <kuba@kernel.org> Signed-off-by: David S. Miller <davem@davemloft.net>
2020-10-06ethtool: wire up get policies to opsJakub Kicinski1-4/+1
Wire up policies for get commands in struct nla_policy of the ethtool family. Make use of genetlink code attr validation and parsing, as well as allow dumping policies to user space. For every ETHTOOL_MSG_*_GET: - add 'ethnl_' prefix to policy name - add extern declaration in net/ethtool/netlink.h - wire up the policy & attr in ethtool_genl_ops[]. - remove .request_policy and .max_attr from ethnl_request_ops. Obviously core only records the first "layer" of parsed attrs so we still need to parse the sub-attrs of the nested header attribute. v2: - merge of patches 1 and 2 from v1 - remove stray empty lines in ops - also remove .max_attr Signed-off-by: Jakub Kicinski <kuba@kernel.org> Signed-off-by: David S.

2020-03-24ethtool: fix reference leak in some *_SET handlersMichal Kubecek1-1/+3
Andrew noticed that some handlers for *_SET commands leak a netdev reference if required ethtool_ops callbacks do not exist. A simple reproducer would be e.g. ip link add veth1 type veth peer name veth2 ethtool -s veth1 wol g ip link del veth1 Make sure dev_put() is called when ethtool_ops check fails. v2: add Fixes tags Fixes: a53f3d41e4d3 ("ethtool: set link settings with LINKINFO_SET request") Fixes: bfbcfe2032e7 ("ethtool: set link modes related data with LINKMODES_SET request") Fixes: e54d04e3afea ("ethtool: set message mask with DEBUG_SET request") Fixes: 8d425b19b305 ("ethtool: set wake-on-lan settings with WOL_SET request") Reported-by: Andrew Lunn <andrew@lunn.ch> Signed-off-by: Michal Kubecek <mkubecek@suse.cz> Reviewed-by: Andrew Lunn <andrew@lunn.ch> Reviewed-by: Florian Fainelli <f.fainelli@gmail.com> Reviewed-by: Jakub Kicinski <kuba@kernel.org> Signed-off-by: David S.

2020-03-13ethtool: rename ethnl_parse_header() to ethnl_parse_header_dev_get()Michal Kubecek1-2/+3
Andrew Lunn pointed out that even if it's documented that ethnl_parse_header() takes reference to network device if it fills it into the target structure, its name doesn't make it apparent so that corresponding dev_put() looks like mismatched. Rename the function ethnl_parse_header_dev_get() to indicate that it takes a reference.

2020-01-27ethtool: add WOL_NTF notificationMichal Kubecek1-1/+3
Send ETHTOOL_MSG_WOL_NTF notification whenever wake-on-lan settings of a device are modified using ETHTOOL_MSG_WOL_SET netlink message or ETHTOOL_SWOL ioctl request. As notifications can be received by anyone, do not include SecureOn(tm) password in notification messages. Signed-off-by: Michal Kubecek <mkubecek@suse.cz> Signed-off-by: David S.

Implement WOL_GET request to get wake-on-lan settings for a device, traditionally available via ETHTOOL_GWOL ioctl request. As part of the implementation, provide symbolic names for wake-on-line modes as ETH_SS_WOL_MODES string set.
