treewide: Add SPDX license identifier for more missed files

2019-05-21T08:50:45+00:00

Add SPDX license identifiers to all files which: - Have no license information of any form - Have MODULE_LICENCE("GPL*") inside which was used in the initial scan/conversion to ignore the file These files fall under the project license, GPL v2 only. The resulting SPDX license identifier is: GPL-2.0-only Signed-off-by: Thomas Gleixner Signed-off-by: Greg Kroah-Hartman

net: veth: use generic helper to report timestamping info

2019-04-12T23:26:37+00:00

For reporting the common set of SW timestamping capabilities, use ethtool_op_get_ts_info() instead of re-implementing it. Signed-off-by: Julian Wiedmann Signed-off-by: David S. Miller

veth: Fix -Wformat-truncation

2019-02-23T21:44:58+00:00

Provide a precision hint to snprintf() in order to eliminate a -Wformat-truncation warning provided below. A maximum of 11 characters is allowed to reach a maximum of 32 - 1 characters given a possible maximum value of queues using up to UINT_MAX which occupies 10 characters. Incidentally 11 is the number of characters for "xdp_packets" which is the largest string we append. drivers/net/veth.c: In function 'veth_get_strings': drivers/net/veth.c:118:47: warning: '%s' directive output may be truncated writing up to 31 bytes into a region of size between 12 and 21 [-Wformat-truncation=] snprintf(p, ETH_GSTRING_LEN, "rx_queue_%u_%s", ^~ drivers/net/veth.c:118:5: note: 'snprintf' output between 12 and 52 bytes into a destination of size 32 snprintf(p, ETH_GSTRING_LEN, "rx_queue_%u_%s", ^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ i, veth_rq_stats_desc[j].desc); ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ Signed-off-by: Florian Fainelli Signed-off-by: David S.

veth: Mark expected switch fall-throughs

2019-02-08T19:51:52+00:00

In preparation to enabling -Wimplicit-fallthrough, mark switch cases where we are expecting to fall through. Warning level 3 was used: -Wimplicit-fallthrough=3 This patch is part of the ongoing efforts to enabling -Wimplicit-fallthrough. Signed-off-by: Gustavo A. R. Silva Signed-off-by: David S. Miller

net: Add extack argument to rtnl_create_link

2018-11-06T23:00:45+00:00

Add extack arg to rtnl_create_link and add messages for invalid number of Tx or Rx queues. Signed-off-by: David Ahern Signed-off-by: David S. Miller

veth: Add ethtool statistics support for XDP

2018-10-16T04:58:46+00:00

Expose per-queue stats for ethtool -S. As there are only rx queues, and rx queues are used only when XDP is used, per-queue counters are only rx XDP ones. Example: $ ethtool -S veth0 NIC statistics: peer_ifindex: 11 rx_queue_0_xdp_packets: 28601434 rx_queue_0_xdp_bytes: 1716086040 rx_queue_0_xdp_drops: 28601434 rx_queue_1_xdp_packets: 17873050 rx_queue_1_xdp_bytes: 1072383000 rx_queue_1_xdp_drops: 17873050 Signed-off-by: Toshiaki Makita Signed-off-by: David S. Miller

veth: Account for XDP packet statistics on rx side

2018-10-16T04:58:46+00:00

On XDP path veth has napi handler so we can collect statistics on per-queue basis for XDP. By this change now we can collect XDP_DROP drop count as well as packets and bytes coming through ndo_xdp_xmit. Packet counters shown by "ip -s link", sysfs stats or /proc/net/dev is now correct for XDP. Signed-off-by: Toshiaki Makita Signed-off-by: David S. Miller

veth: Account for packet drops in ndo_xdp_xmit

2018-10-16T04:58:46+00:00

Use existing atomic drop counter. Since drop path is really an exceptional case here, I'm thinking atomic ops would not hurt the performance. XDP packets and bytes are not counted in ndo_xdp_xmit, but will be accounted on rx side by the following commit. Signed-off-by: Toshiaki Makita Signed-off-by: David S. Miller

veth: rename pcpu_vstats as pcpu_lstats

2018-09-19T02:52:23+00:00

struct pcpu_vstats and pcpu_lstats have same members and usage, and pcpu_lstats is used in many files, so rename pcpu_vstats as pcpu_lstats to reduce duplicate definition Signed-off-by: Zhang Yu Signed-off-by: Li RongQing Signed-off-by: David S. Miller

Two new tls tests added in parallel in both net and net-next. Used Stephen Rothwell's linux-next resolution. Signed-off-by: David S. Miller
