* Copy the user provided sockaddr into a normalized sockaddr in rtrequest()claudio2019-06-131-16/+59
| | | | | | | | | | before adding it to the routing table. The rtable code is doing memcmp() of those rt_dest sockaddrs so it is important that they are stored in a canonical form. To do this struct domain is extended to include the sockaddr size for this address family. OK bluhm@ anton@ Reported-by: syzbot+10fe9cd8d0211c562ead@syzkaller.appspotmail.com

* Do not check for IFF_RUNNING inside bstp_initialization().mpi2019-05-131-3/+2
| | | | | | | This allows to set such flag after completing the initialization of a bridge and still have bstp_tick() be scheduled from the begining. Fix a regression reported by and ok markus@
* Deal with the case where bridge_getbif() can return NULL.mpi2019-05-131-3/+4
| | | | | | | | Since `bif' are removed from the interface list before calling smr_barrier() and the hash queue is cleaned up afterward, it is possible to find an ifidx with bridge_rtlookup() that won't match to any `bif'. Fix a panic reported by Hrvoje Popovski, ok visa@
* Switch the list of span interfaces and interfaces to SMR.mpi2019-05-123-86/+123
| | | | | | | | | | | | This removes the KERNEL_LOCK() around the list iteration in bridge_enqueue(). Since the NET_LOCK() isn't protecting any data structure, release it early in all the code paths coming from the Network Stack to prevent possible deadlock situations with smr_barrier(). bridge_input() is still KERNEL_LOCK()ed as well as bridge_filterrule(). ok visa@

* A trunk(4) usually stays up when the link state of one of its membersflorian2019-05-111-1/+3
| | | | | | | | | changes. While we do get RTM_IFINFO messages for the (physical) member interfaces there is no indication that something changed from the trunk(4) interface. It is helpful to get this information in userland from the trunk so that userland daemons do not need to track interface membership by themselves. OK phessler
* Make rt_mpls_set() be more strict in what it accepts. Also ensure thatclaudio2019-05-112-10/+16
| | | | | | | | | | the RTF_MPLS can't be toggled without rt_mpls_set() being called. While RTF_MPLS is part of RTF_FMASK it should be excluded from the flags and mask when they are applied to the route since toggling it requires a call to rt_mpls_set().

* Add port protection support to switch(4). The behavior copies that ofakoshibe2019-05-103-7/+34
| | | | | | | | | | | | | bridge(4), where the SIOCBRDGSIFPROT ioctl can be used to add a port to up to 31 protected domains. This allows configuration by specifying a list of IDs to the 'protected' option in ifconfig(8): # ifconfig switch0 protected pair1 1,2,.. Domain membership is checked for unicast, flooded (broadcast), and local (host-network-bound, e.g. trunk) traffic. OK benno@

* pretty much all of tun_wakeup needs to be protected with KERNEL_LOCKdlg2019-05-011-1/+3
| | | | | | | | | | | | tun_wakeup is called from the network stack, which generally runs with NET_LOCK, not KERNEL_LOCK, which is a problem when it calls into things like csignal or kq code. this started causing corruption and panics of a list inside the kq code, which got reported to bugs@. this version of the fix is ok mpi@ (even though he hasn't seen it) an earlier but far trickier fix was ok visa@ the bug was reported by Olivier Antoine, and again by jmc@ privately.

* don't have lacp input push lacp packets into the trunkports bpf again.dlg2019-04-291-11/+1
| | | | | | if_input already runs bpf for all packets on a trunkport. having lacp code do it again means packets are seen twice by bpf filters twice, which is misleading.
* Removes the KERNEL_LOCK() from bridge(4)'s output fast-path.mpi2019-04-288-163/+198
| | | | | | | | This redefines the ifp <-> bridge relationship. No lock can be currently used across the multiples contexts where the bridge has tentacles to protect a pointer, use an interface index. Tested by various, ok dlg@, visa@
