2011-03-27net: fix ethtool->set_flags not intended -EINVAL return valueStanislaw Gruszka1-0/+1
After commit d5dbda23804156ae6f35025ade5307a49d1db6d7 "ethtool: Add support for vlan accleration.", drivers that have NETIF_F_HW_VLAN_TX, and/or NETIF_F_HW_VLAN_RX feature, but do not allow enable/disable vlan acceleration via ethtool set_flags, always return -EINVAL from that function. Fix by returning -EINVAL only if requested features do not match current settings and can not be changed by driver. Change any driver that define ethtool->set_flags to use ethtool_invalid_flags() to avoid similar problems in the future (also on drivers that do not have the problem). Tested with modified (to reproduce this bug) myri10ge driver. Cc: stable@kernel.org # 2.6.37+ Signed-off-by: Stanislaw Gruszka <sgruszka@redhat.com> Signed-off-by: David S.

This introduces a new framework to handle device features setting. It consists of: - new fields in struct net_device: + hw_features - features that hw/driver supports toggling + wanted_features - features that user wants enabled, when possible - new netdev_ops: + feat = ndo_fix_features(dev, feat) - API checking constraints for enabling features or their combinations + ndo_set_features(dev) - API updating hardware state to match changed dev->features - new ethtool commands: + ETHTOOL_GFEATURES/ETHTOOL_SFEATURES: get/set dev->wanted_features and trigger device reconfiguration if resulting dev->features changed + ETHTOOL_GSTRINGS(ETH_SS_FEATURES): get feature bits names (meaning) Signed-off-by: Michał Mirosław <mirq-linux@rere.qmqm.pl> Signed-off-by: David S.

2010-12-10ethtool: Report link-down while interface is downBen Hutchings1-1/+3
While an interface is down, many implementations of ethtool_ops::get_link, including the default, ethtool_op_get_link(), will report the last link state seen while the interface was up. In general the current physical link state is not available if the interface is down. Define ETHTOOL_GLINK to reflect whether the interface *and* any physical port have a working link, and consistently return 0 when the interface is down.

2010-09-17ethtool, ixgbe: Move RX n-tuple mask fixup to ethtoolBen Hutchings1-2/+3
The ethtool utility does not set masks for flow parameters that are not specified, so if both value and mask are 0 then this must be treated as equivalent to a mask with all bits set. Currently that is done in the only driver that implements RX n-tuple filtering, ixgbe. Move it to the ethtool core. Signed-off-by: Ben Hutchings <bhutchings@solarflare.com> Signed-off-by: David S.

2010-09-15ethtool: Remove unimplemented flow specification typesBen Hutchings1-19/+2
struct ethtool_rawip4_spec and struct ethtool_ether_spec are neither commented nor used by any driver, so remove them. Adjust padding in the user-visible unions that included these structures. Fix references to struct ethtool_rawip4_spec in ethtool_get_rx_ntuple(), which should use struct ethtool_usrip4_spec. struct ethtool_usrip4_spec cannot hold IPv6 host addresses and there is no separate structure that can, so remove ETH_RX_NFC_IP6 and the reference to it in niu.

2010-09-15ethtool: Complete kernel-doc comments for RX flow filter and hash controlBen Hutchings1-16/+113
There are now several interfaces within the ethtool API for getting and setting RX flow filtering and hashing behaviour, most of which are poorly documented.

2010-06-30ethtool: Add support for control of RX flow hash indirectionBen Hutchings1-0/+15
Many NICs use an indirection table to map an RX flow hash value to one of an arbitrary number of queues (not necessarily a power of 2). It can be useful to remove some queues from this indirection table so that they are only used for flows that are specifically filtered there. It may also be useful to weight the mapping to account for user processes with the same CPU-affinity as the RX interrupts.

2010-06-30ethtool: Change ethtool_op_set_flags to validate flagsBen Hutchings1-1/+1
ethtool_op_set_flags() does not check for unsupported flags, and has no way of doing so. This means it is not suitable for use as a default implementation of ethtool_ops::set_flags. Add a 'supported' parameter specifying the flags that the driver and hardware support, validate the requested flags against this, and change all current callers to pass this parameter. Change some other trivial implementations of ethtool_ops::set_flags to call ethtool_op_set_flags().

2010-06-29ethtool: Fix potential user buffer overflow for ETHTOOL_{G, S}RXFHBen Hutchings1-0/+2
struct ethtool_rxnfc was originally defined in 2.6.27 for the ETHTOOL_{G,S}RXFH command with only the cmd, flow_type and data fields. It was then extended in 2.6.30 to support various additional commands. These commands should have been defined to use a new structure, but it is too late to change that now. Since user-space may still be using the old structure definition for the ETHTOOL_{G,S}RXFH commands, and since they do not need the additional fields, only copy the originally defined fields to and from user-space.

Debatable -- the current comment is located at the callsite of ops->get_sset_count(), which is where an implementor might think to add a new call. Not all the numeric fields in ethtool_drvinfo are obtained from ->get_sset_count(). Hence the "some" in the attached patch to include/linux/ethtool.h, addressing your comment. > [...] >> +static noinline int ethtool_get_sset_info(struct net_device *dev, >> + void __user *useraddr) >> +{ > [...] >> + /* calculate size of return buffer */ >> + for (i = 0; i< 64; i++) >> + if (sset_mask& (1ULL<< i)) >> + n_bits++; > [...] > > We have a function for this: > > n_bits = hweight64(sset_mask); Agreed.

2009-10-07ethtool: Add reset operationBen Hutchings1-0/+32
After updating firmware stored in flash, users may wish to reset the relevant hardware and start the new firmware immediately. This should not be completely automatic as it may be disruptive. A selective reset may also be useful for debugging or diagnostics. This adds a separate reset operation which takes flags indicating the components to be reset. Drivers are allowed to reset only a subset of those requested, and must indicate the actual subset. This allows the use of generic component masks and some future expansion.
