In general, global structures manipulated in the softnet codepath only require a splsoftnet() protection when they are modified in process (ioctl) context.

* Stop mixing interface address flags with routing entry ones.mpi2014-03-271-7/+5
| | | | | | | | | | Instead of always copying ifa_flags to the routing entry flags when creating a route by calling rtinit(), explicitly pass the RTF_CLONING flag when required. This means ifa_flags are now *only* used to check if an address has an associated route that was created by the kernel auto-magically. ok benno@

* Some follow-up fixes for IFID collision handling in IPv6CP.stsp2014-01-071-2/+2
| | | | | | | | | | | | | | | Really change the link-local address in the unlikely event of an IFID collision, instead of going into an infinite conf-nak loop with the peer. To make the netinet6 code use the IPv6CP IFID in a new link-local address, in6_ifattach_linklocal() must accept a provided IFID. Replace the unused 'altifp' parameter with a new 'ifid' parameter for this purpose. Always use the latest suggested address in IPv6CP replies, even if the task to update the interface's address hasn't run yet. Also, clear the ifindex (KAME hack) in addresses sent during IPv6CP. ok mpi
* Change the way protocol multicast addresses are linked to an interface.mpi2013-11-281-182/+34
| | | | | | | | | | | | | | | | | | | | | | Instead of linking multicast records to the first configured address of the corresponding protocol, making this address and its position in the global list special, add them to a new list directly linked to the interface descriptor. This new multicast address list is similar to the address list, all its elements contain a protocol agnostic part. This design allows us to be able to join a multicast group without necessarily having a configured address. That means IPv6 multicast kludges are no longer needed. Another benefit is to be able to add and remove an IP address from an interface without worrying about multicast records. That means that the global IPv4 list is no longer needed since the first configured address of an interface is no longer special. This new list might also be extended in the future to contain the link-layer addresses used to configure hardware filters. Tested by sthen@ and weerd@, ok mikeb@

* In in6_update_ifa(), don't set the TENTATIVE flag on an IPv6 address thatstsp2013-11-131-2/+3
| | | | | | | | | | | is marked as NODAD. Since we're not gonna do duplicate address detection for this address, the TENTATIVE flag won't get cleared, rendering the address unusable. The existing logic only checked whether DAD was enabled for the interface, but DAD can be configured on a per-address basis. ok sthen@ as part of a larger diff

Assign new syscall numbers for (almost all) the syscalls that involve the affected types, including anything with time_t, timeval, itimerval, timespec, rusage, dirent, stat, or kevent arguments. Add a d_off member to struct dirent and replace getdirentries() with getdents(), thus immensely simplifying and accelerating telldir/seekdir. Build perl with -DBIG_TIME. Bump the major on every single base library: the compat bits included here are only good enough to make the transition; the T32 compat option will be burned as soon as we've reached the new world are are happy with the snapshots for all architectures. DANGER: ABI incompatibility. Updating to this kernel requires extra work or you won't be able to login: install a snapshot instead.
