* In r227207, to fix the issue with possible NULL inp_socket pointertrociny2013-07-042-11/+7
| | | | | | | | | | | | | | | | | | | | | dereferencing, when checking for SO_REUSEPORT option (and SO_REUSEADDR for multicast), INP_REUSEPORT flag was introduced to cache the socket option. It was decided then that one flag would be enough to cache both SO_REUSEPORT and SO_REUSEADDR: when processing SO_REUSEADDR setsockopt(2), it was checked if it was called for a multicast address and INP_REUSEPORT was set accordingly. Unfortunately that approach does not work when setsockopt(2) is called before binding to a multicast address: the multicast check fails and INP_REUSEPORT is not set. Fix this by adding INP_REUSEADDR flag to unconditionally cache SO_REUSEADDR. PR: 179901 Submitted by: Michael Gmelin freebsd grem.de (initial version) Reviewed by: rwatson MFC after: 1 week
* - Allow ND6_IFF_AUTO_LINKLOCAL for IFT_BRIDGE. An interface with IFT_BRIDGEhrs2013-07-024-15/+51
| | | | | | | | | | | | | | | | | | | | | | | is initialized with !ND6_IFF_AUTO_LINKLOCAL && !ND6_IFF_ACCEPT_RTADV regardless of net.inet6.ip6.accept_rtadv and net.inet6.ip6.auto_linklocal. To configure an autoconfigured link-local address (RFC 4862), the following rc.conf(5) configuration can be used: ifconfig_bridge0_ipv6="inet6 auto_linklocal" - if_bridge(4) now removes IPv6 addresses on a member interface to be added when the parent interface or one of the existing member interfaces has an IPv6 address. if_bridge(4) merges each link-local scope zone which the member interfaces form respectively, so it causes address scope violation. Removal of the IPv6 addresses prevents it. - if_lagg(4) now removes IPv6 addresses on a member interfaces unconditionally. - Set reasonable flags to non-IPv6-capable interfaces.

| | | | | | | | | | | | | | | | | | Address. Although KAME implementation used FF02:0:0:0:0:2::/96 based on older versions of draft-ietf-ipngwg-icmp-name-lookup, it has been changed in RFC 4620. The kernel always joins the /104-prefixed address, and additionally does /96-prefixed one only when net.inet6.icmp6.nodeinfo_oldmcprefix=1. The default value of the sysctl is 1. ping6(8) -N flag now uses /104-prefixed one. When this flag is specified twice, it uses /96-prefixed one instead.

* Simplify in6_setscope() function to get better performance.ae2013-01-101-46/+17
| | | | | | | | | | | | Currently we use interface indeces as zone IDs for link-local and interface-local scopes, and since we don't have any tool to configure zone IDs, there is no need to acquire the afdata lock several times per packet only to read if_index value. So, now in6_setscope reads zone IDs for interface-local, link-local and global scopes without a lock. Sponsored by: Yandex LLC MFC after: 2 weeks

* The in6_setscope() function determines the scope zone id of an addressae2013-01-091-14/+15
| | | | | | | | | | | | and embeds it into address. Inside the kernel we keep addresses with embedded zone id only for two scopes: link-local and interface-local. For other scopes this function is nop in most cases. To reduce an overhead of locking, first check that address is capable for embedding. Also, handle the loopback address before acquire the lock.

| | | | | | | | | | | | | | | | | | all interested parties in case if interface flag IFF_UP has changed. However, not only SIOCSIFFLAGS can raise the flag, but SIOCAIFADDR and SIOCAIFADDR_IN6 can, too. The actual |= is done not in the protocol code, but in code of interface drivers. To fix this historical layering violation, we will check whether ifp->if_ioctl(SIOCSIFADDR) raised the IFF_UP flag, and if it did, run the if_up() handler. This fixes configuring an address under CARP control on an interface that was initially !IFF_UP. P.S. I intentionally omitted handling the IFF_SMART flag. This flag was never ever used in any driver since it was introduced, and since it means another layering violation, it should be garbage collected instead of pretended to be supported.
