This patch series extends inet diag with cgroup v2 ID attribute and
filter. Which allows investigate sockets on per cgroup basis. Patch for
ss is already sent to iproute2-next mailing list.
Ok, this looks fine, series applied.
Although I wish you could have done something like only emit the cgroup
attribute if it is a non-default value (zero, or whatever it is).
Every time a new socket attribute is added, it makes long dumps more
and more expensive.
Maybe then put it under condition
if (ext & (1 << (INET_DIAG_CLASS_ID - 1)) ||
ext & (1 << (INET_DIAG_TCLASS - 1))) {
like legacy cgroup id INET_DIAG_CLASS_ID above.
(userspace requests it by INET_DIAG_TCLASS because INET_DIAG_CLASS_ID does not
fit into field)
