New Revision: 259638
URL: http://svnweb.freebsd.org/changeset/base/259638
Log:
Use more fine-grained kvm(3) symbol lookup: routing code
retrieves only
necessary symbols needed per subsystem. Main kvm(3) init is now
delayed
as much as possbile. This finally fixes performance issues
reported in
kern/167204.
Some non-working code (ng_socket.ko symbol addresses
calculation) removed.
Some global variables eliminated.
PR: kern/167204
MFC after: 4 weeks
Hi Alexander,
"netstat -gW" no more correctly detect inet4 MROUTING after this
commit (that was MFC to stable).
Behavior of my MROUTING enabled system before your commit:
Whoops. Fixed in r265096, thank you!
