net: drop the weight argument from netif_napi_add

2022-09-29T01:57:14Z

We tell driver developers to always pass NAPI_POLL_WEIGHT as the weight to netif_napi_add(). This may be confusing to newcomers, drop the weight argument, those who really need to tweak the weight can use netif_napi_add_weight().

net: ethernet: move from strlcpy with unused retval to strscpy

2022-08-31T21:11:26Z

Follow the advice of the below link and prefer 'strscpy' in this subsystem. Conversion is 1:1 because the return value is not used. Generated by a coccinelle script.

net: add skb_[inner_]tcp_all_headers helpers

2022-07-02T15:22:25Z

Most drivers use "skb_transport_offset(skb) + tcp_hdrlen(skb)" to compute headers length for a TCP packet, but others use more convoluted (but equivalent) ways. Add skb_tcp_all_headers() and skb_inner_tcp_all_headers() helpers to harmonize this a bit. Signed-off-by: Eric Dumazet Signed-off-by: David S. Miller

net_tstamp: add new flag HWTSTAMP_FLAG_BONDED_PHC_INDEX

2021-12-14T12:28:24Z

Since commit 94dd016ae538 ("bond: pass get_ts_info and SIOC[SG]HWTSTAMP ioctl to active device") the user could get bond active interface's PHC index directly. But when there is a failover, the bond active interface will change, thus the PHC index is also changed. This may break the user's program if they did not update the PHC timely. This patch adds a new hwtstamp_config flag HWTSTAMP_FLAG_BONDED_PHC_INDEX. When the user wants to get the bond active interface's PHC, they need to add this flag and be aware the PHC index may be changed. With the new flag. All flag checks in current drivers are removed. Only the checking in net_hwtstamp_validate() is kept. Suggested-by: Jakub Kicinski Signed-off-by: Hangbin Liu Signed-off-by: David S. Miller

bpf: Let bpf_warn_invalid_xdp_action() report more info

2021-12-13T21:28:27Z

In non trivial scenarios, the action id alone is not sufficient to identify the program causing the warning. Before the previous patch, the generated stack-trace pointed out at least the involved device driver. Let's additionally include the program name and id, and the relevant device name. If the user needs additional infos, he can fetch them via a kernel probe, leveraging the arguments added here.
