netdev-genl: create a simple family for netdev stuff

2023-02-03T04:48:23+00:00

Add a Netlink spec-compatible family for netdevs. This is a very simple implementation without much thought going into it. It allows us to reap all the benefits of Netlink specs, one can use the generic client to issue the commands: $ ./cli.py --spec netdev.yaml --dump dev_get [{'ifindex': 1, 'xdp-features': set()}, {'ifindex': 2, 'xdp-features': {'basic', 'ndo-xmit', 'redirect'}}, {'ifindex': 3, 'xdp-features': {'rx-sg'}}] the generic python library does not have flags-by-name support, yet, but we also don't have to carry strings in the messages, as user space can get the names from the spec.

devlink: move code to a dedicated directory

2023-01-06T06:12:00+00:00

The devlink code is hard to navigate with 13kLoC in one file. I really like the way Michal split the ethtool into per-command files and core. It'd probably be too much to split it all up, but we can at least separate the core parts out of the per-cmd implementations and put it in a directory so that new commands can be separate files. Move the code, subsequent commit will do a partial split. Reviewed-by: Jacob Keller Reviewed-by: Jiri Pirko Signed-off-by: Jakub Kicinski

net: skb: export skb drop reaons to user by TRACE_DEFINE_ENUM

2022-09-07T14:28:08+00:00

As Eric reported, the 'reason' field is not presented when trace the kfree_skb event by perf: $ perf record -e skb:kfree_skb -a sleep 10 $ perf script ip_defrag 14605 [021] 221.614303: skb:kfree_skb: skbaddr=0xffff9d2851242700 protocol=34525 location=0xffffffffa39346b1 reason: The cause seems to be passing kernel address directly to TP_printk(), which is not right. As the enum 'skb_drop_reason' is not exported to user space through TRACE_DEFINE_ENUM(), perf can't get the drop reason string from the 'reason' field, which is a number. Therefore, we introduce the macro DEFINE_DROP_REASON(), which is used to define the trace enum by TRACE_DEFINE_ENUM(). With the help of DEFINE_DROP_REASON(), now we can remove the auto-generate that we introduced in the commit ec43908dd556 ("net: skb: use auto-generation to convert skb drop reason to string"), and define the string array 'drop_reasons'. Hmmmm...now we come back to the situation that have to maintain drop reasons in both enum skb_drop_reason and DEFINE_DROP_REASON. But they are both in dropreason.h, which makes it easier. After this commit, now the format of kfree_skb is like this: $ cat /tracing/events/skb/kfree_skb/format name: kfree_skb ID: 1524 format: field:unsigned short common_type; offset:0; size:2; signed:0; field:unsigned char common_flags; offset:2; size:1; signed:0; field:unsigned char common_preempt_count; offset:3; size:1; signed:0; field:int common_pid; offset:4; size:4; signed:1; field:void * skbaddr; offset:8; size:8; signed:0; field:void * location; offset:16; size:8; signed:0; field:unsigned short protocol; offset:24; size:2; signed:0; field:enum skb_drop_reason reason; offset:28; size:4; signed:0; print fmt: "skbaddr=%p protocol=%u location=%p reason: %s", REC->skbaddr, REC->protocol, REC->location, __print_symbolic(REC->reason, { 1, "NOT_SPECIFIED" }, { 2, "NO_SOCKET" } ......

net: skb: use auto-generation to convert skb drop reason to string

2022-06-07T10:51:41+00:00

It is annoying to add new skb drop reasons to 'enum skb_drop_reason' and TRACE_SKB_DROP_REASON in trace/event/skb.h, and it's easy to forget to add the new reasons we added to TRACE_SKB_DROP_REASON. TRACE_SKB_DROP_REASON is used to convert drop reason of type number to string. For now, the string we passed to user space is exactly the same as the name in 'enum skb_drop_reason' with a 'SKB_DROP_REASON_' prefix. Therefore, we can use 'auto-generation' to generate these drop reasons to string at build time. The new source 'dropreason_str.c' will be auto generated during build time, which contains the string array 'const char * const drop_reasons[]'.
