net: Use skb accessors in network drivers

2019-07-23T03:47:56+00:00

In preparation for unifying the skb_frag and bio_vec, use the fine accessors which already exist and use skb_frag_t instead of struct skb_frag_struct. Signed-off-by: Matthew Wilcox (Oracle) Signed-off-by: David S. Miller

net: tehuti: replace dev_kfree_skb_irq by dev_consume_skb_irq for drop profiles

2019-02-07T01:38:15+00:00

dev_consume_skb_irq() should be called in bdx_tx_cleanup() when skb xmit done. It makes drop profiles(dropwatch, perf) more friendly. Signed-off-by: Yang Wei Signed-off-by: David S. Miller

net: tehuti: remove redundant pointer skb

2018-07-05T10:33:39+00:00

Pointer skb is being assigned but is never used hence it is redundant and can be removed. Cleans up clang warning: warning: variable 'skb' set but not used [-Wunused-but-set-variable] Signed-off-by: Colin Ian King Signed-off-by: David S. Miller

net: tehuti: don't process data if it has not been copied from userspace

2017-07-20T05:48:02+00:00

The array data is only populated with valid information from userspace if cmd != SIOCDEVPRIVATE, other cases the array contains garbage on the stack. The subsequent switch statement acts on a subcommand in data[0] which could be any garbage value if cmd is SIOCDEVPRIVATE which seems incorrect to me. Instead, just return EOPNOTSUPP for the case where cmd == SIOCDEVPRIVATE to avoid this issue. As a side note, I suspect that the original intention of the code was for this ioctl to work just for cmd == SIOCDEVPRIVATE (and the current logic is reversed). However, I don't wont to change the current semantics in case any userspace code relies on this existing behaviour.

net: tehuti: use new api ethtool_{get|set}_link_ksettings

2017-03-27T23:00:07+00:00

The ethtool api {get|set}_settings is deprecated. We move this driver to new api {get|set}_link_ksettings. As I don't have the hardware, I'd be very pleased if someone may test this patch. Signed-off-by: Philippe Reynes Signed-off-by: David S. Miller

drivers: net: generalize napi_complete_done()

napi_complete_done() allows to opt-in for gro_flush_timeout, added back in linux-3.19, commit 3b47d30396ba ("net: gro: add a per device gro flush timer") This allows for more efficient GRO aggregation without sacrifying latencies. Signed-off-by: Eric Dumazet Signed-off-by: David S. Miller
