* Do not use the flow of the first fragment to store ECN information.bluhm2019-08-261-5/+6
| | | | | | Handle the ECN in the fragment queue. Reported-by: syzbot+0aa80b25e9041001cac8@syzkaller.appspotmail.com fix from FreeBSD; OK claudio@
* Instead of calculating the mbuf packet header length here and there,bluhm2018-09-101-9/+2
| | | | | | put the algorithm into a new function m_calchdrlen(). Also set an uninitialized m_len to 0 in NFS code. OK claudio@
* During fragment reassembly, mbuf chains with packet headers werebluhm2018-09-101-2/+5
| | | | | | | created. Add a new function m_removehdr() do convert packet header mbufs within the chain to regular mbufs. Assert that the mbuf at the beginning of the chain has a packet header. found by Maxime Villard in NetBSD; from markus@; OK claudio@
* frag6_slowtimo: push NET_LOCK into frag6_freef around icmp6_error.cheloha2018-08-221-8/+6
| | | | | | | | | | | | | | | icmp6_error() still probably needs the NET_LOCK, as the call chain icmp6_error -> icmp6_reflect -> rt_match -> rt_clone -> rtrequest is possible. The fragment discard loop in frag6_slowtimo and the other cleanup bits in frag6_freef do not require it however. So push the lock down into frag6_freef around icmp6_error. Prompted by mpi. Discussed with bluhm and kn. Regress test help by bluhm. Additional testing by kn. ok kn@ visa@ mpi@
* The function ip6_get_prevhdr() did return a pointer into a mbuf.bluhm2018-02-011-9/+15
| | | | | | It was not guaranteed that the mbuf data was not somewhere else in the chain. So return an offset and do a proper mbuf pulldown. found by Maxime Villard; from NetBSD; with markus@; OK deraadt@

* Serialize access to the IPv6 reassembly queue with a mutex.visa2017-11-071-83/+71
| | | | | | | | | This lets the code run without KERNEL_LOCK() and NET_LOCK(). In addition, this patch reorganizes a part of the code, to move some of the memory release operations outside the critical section. Input and OK mpi@, OK florian@, an earlier version OK bluhm@

* Use percpu counters for ip6statjca2017-02-051-9/+9
| | | | | | | | | Try to follow the existing examples. Some notes: - don't implement counters_dec() yet, which could be used in two similar chunks of code. Let's see if there are more users first. - stop incrementing IPv6-specific mbuf stats, IPv4 has no equivalent. Input from mpi@, ok bluhm@ mpi@
* Assert that every slow/fast timeout routine is called at IPL_SOFTNET.mpi2016-11-281-4/+3
| | | | This removes multipe recursive splsoftnet()/splx() dances.
* When the IPv6 network stack receives an empty non atomic fragment,bluhm2016-10-241-1/+7
| | | | | | | | just drop it. It can never overlap existing content, there is no ambiguous payload. So save resources and do not try to insert it into the queue. This makes our IPv6 stack behave like pf fragment reassembly. OK deraadt@

* Store a unique ID, an interface index, rather than a pointer to thempi2015-06-161-2/+2
| | | | | | | | | | | | | | | receiving interface in the packet header of every mbuf. The interface pointer should now be retrieved when necessary with if_get(). If a NULL pointer is returned by if_get(), the interface has probably been destroy/removed and the mbuf should be freed. Such mechanism will simplify garbage collection of mbufs and limit problems with dangling ifp pointers. Tested by jmatthew@ and krw@, discussed with many. ok mikeb@, bluhm@, dlg@

* "struct pkthdr" holds a routing table ID, not a routing domain one.mpi2014-04-141-2/+2
| | | | | | | | | | | | | | Avoid the confusion by using an appropriate name for the variable. Note that since routing domain IDs are a subset of the set of routing table IDs, the following idiom is correct: rtableid = rdomain But to get the routing domain ID corresponding to a given routing table ID, you must call rtable_l2(9). claudio@ likes it, ok mikeb@
