tools/loongarch: Use __SIZEOF_LONG to define BITS_PER_LONG

2023-04-19T04:07:34Z

Although __SIZEOF_POINTER__ is equal to _SIZEOF_LONG__ on LoongArch, it is better to use __SIZEOF_LONG__ to define __BITS_PER_LONG to keep consistent between arch/loongarch/include/uapi/asm/bitsperlong.h and tools/arch/loongarch/include/uapi/asm/bitsperlong.h.

tools/mm/page_owner_sort.c: fix TGID output when cull=tg is used

When using cull option with 'tg' flag, the fprintf is using pid instead of tgid. It should use tgid instead.

selftests/bpf: xdp_hw_metadata remove bpf_printk and add counters

2023-04-13T18:15:10Z

The tool xdp_hw_metadata can be used by driver developers implementing XDP-hints metadata kfuncs. Remove all bpf_printk calls, as the tool already transfers all the XDP-hints related information via metadata area to AF_XDP userspace process. Add counters for providing remaining information about failure and skipped packet events.

selftests: openvswitch: adjust datapath NL message declaration

2023-04-13T17:01:23Z

The netlink message for creating a new datapath takes an array of ports for the PID creation. This shouldn't cause much issue but correct it for future cases where we need to do decode of datapath information that could include the per-cpu PID map.

selftests: mptcp: userspace pm: uniform verify events

2023-04-13T16:58:55Z

Simply adding a "sleep" before checking something is usually not a good idea because the time that has been picked can not be enough or too much. The best is to wait for events with a timeout. In this selftest, 'sleep 0.5' is used more than 40 times. It is always used before calling a 'verify_*' function except for this verify_listener_events which has been added later. At the end, using all these 'sleep 0.5' seems to work: the slow CIs don't complain so far. Also because it doesn't take too much time, we can just add two more 'sleep 0.5' to uniform what is done before calling a 'verify_*' function. For the same reasons, we can also delay a bigger refactoring to replace all these 'sleep 0.5' by functions waiting for events instead of waiting for a fix time and hope for the best.
