sys/kern : kern_sysctl.c uipc_domain.c
sys/netmpls : mpls_raw.c
Log message:
Push kernel lock down to net_sysctl().
All except PF_MPLS paths are mp-safe:
- net_link_sysctl() and following net_ifiq_sysctl() only return
EOPNOTSUPP;
- uipc_sysctl() - mp-safe atomic access to integers;
- bpf_sysctl() - mp-safe atomic access to integers;
- pflow_sysctl() - returns statistics from per-CPU counters;
- pipex_sysctl() - mp-safe atomic access to integer;
Push kernel lock down to mpls_sysctl(). sysctl_int_bounded() do copying
with local variable, so context switch is safe. No need to wire memory
or take `sysctl_lock' rwlock(9).
Keep protocols locked as they was include pages wiring. Copying will not
sleep - no network slowdown while doing it with net lock held.
