- Use refcount(9) API to manage node and hook refcounting.

- Make ng_unref_node() void, since caller shouldn't be interested in whether node is valid after call or not, since it can't be guaranteed to be valid. [1] Ok from: julian [1]

This reversal may give some modules empty set_pcpu or set_vnet sections, but these are harmless.

Increase the target buffer for performing NGM_ASCII2BINARY conversion

2010-05-13T16:48:28Z

from 2000 bytes to 20 Kbytes, which now matches the buffer size used for NGM_BINARY2ASCII conversions. The aim of this change is to allow for bigger binary structures to be managed via netgraph ASCII messages, until we come up with an API improvement which would get rid of such arbitrary hardcoded limits.

network stacks, VNET_SYSINIT: - Add VNET_SYSINIT and VNET_SYSUNINIT macros to declare events that will occur each time a network stack is instantiated and destroyed. In the !VIMAGE case, these are simply mapped into regular SYSINIT/SYSUNINIT. For the VIMAGE case, we instead use SYSINIT's to track their order and properties on registration, using them for each vnet when created/ destroyed, or immediately on module load for already-started vnets. - Remove vnet_modinfo mechanism that existed to serve this purpose previously, as well as its dependency scheme: we now just use the SYSINIT ordering scheme. - Implement VNET_DOMAIN_SET() to allow protocol domains to declare that they want init functions to be called for each virtual network stack rather than just once at boot, compiling down to DOMAIN_SET() in the non-VIMAGE case. - Walk all virtualized kernel subsystems and make use of these instead of modinfo or DOMAIN_SET() for init/uninit events. In some cases, convert modular components from using modevent to using sysinit (where appropriate). In some cases, do minor rejuggling of SYSINIT ordering to make room for or better manage events.
