* Introduce new function if_unit(9). This function returns a pointer themvs2021-01-182-19/+55
| | | | | | | | | | | interface descriptor corresponding to the unique name. This descriptor is guaranteed to be valid until if_put(9) is called on the returned pointer. if_unit(9) should replace already existent ifunit() which returns descriptor not safe for dereference when context was switched. This allow us to avoid some use-after-free issues in ioctl(2) path. Also this unifies interface descriptor usage. ok claudio@ sashan@

* kqueue: Revise fd close notificationvisa2021-01-173-33/+121
| | | | | | | | | | | | | | | | | | Deliver file descriptor close notification for __EV_POLL knotes through struct kevent that kqueue_scan() returns. This replaces the previous way of returning EBADF from kqueue_scan(), making it easier to determine what exactly has changed. When a file descriptor is closed, its __EV_POLL knotes are turned into one-shot events and queued for delivery. These knotes are "unregistered" as they are reachable only through the queue of active events. This reduces interference with the normal workings of kqueue. However, more care is needed to avoid leaking knotes. In addition, the unregistering removes a limit on the number of issued knotes. To prevent accumulation of pending fd close notifications, kqpoll_init() flushes the active queue at the start of a kqpoll scan. OK mpi@

| | | | | | | | | the vlan tag we're injecting into the mbuf chain is either straight off the wire and therefore already has the vlan priority encoded, or is straight after it's been set up by vlan(4), which also has the prio already encoded. ok kn@ visa@ mvs@

* The sysctl variable net.inet.ip.forwarding is checked beforebluhm2021-01-161-7/+19
| | | | | | | | | ip_input() passes the packet to ip_forward(). But with an af-to rule, pf(4) calls ip_forward() directly. Check the forwarding sysctl also in pf to get consistent behavior. This requires to set both ip and ip6 forwarding to get packet flow in both directions over af-to rules. OK kn@

| | | | | | | | struct ip_mreq or a struct ip_mreqn. Using struct ip_mreqn allows to pass a interface index instead of specifying the multicast interface via its IP address. This is also the API implemented by Linux and FreeBSD and should help porting software. OK bluhm@ phessler@ robert@

Make the extent start at 0 and immediately reserve the first 16M right away, so that we can change the reserved memory allocator to EX_CONFLICTOK to make allocations succeed if they are already reserved. ok kettenis@

* syncer_thread: sleep without lboltcheloha2021-01-141-6/+25
| | | | | | | | | | | | | | | | | | | | | The syncer_thread() uses lbolt to perform periodic execution. We can do this without lbolt. - Adding a local wakeup(9) channel (syncer_chan) and sleep on it. - Use a local copy of getnsecuptime() to get 1/hz resolution for time measurements. This is much better than using gettime(9), which is wholly unsuitable for this use case. Measure how long we spend in the loop and use this to calculate how long to sleep until the next execution. NB: getnsecuptime() is probably ready to be moved to kern_tc.c and documented. - Using the system uptime instead of the UTC time avoids issues with time jumps. ok mpi@

* kernel, sysctl(8): remove dead variable: tickadjcheloha2021-01-135-15/+6
| | | | | | | | | | | | | | | | | | | | The global "tickadj" variable is a remnant of the old NTP adjustment code we used in the kernel before the current timecounter subsystem was imported from FreeBSD circa 2004 or 2005. Fifteen years hence it is completely vestigial and we can remove it. We probably should have removed it long ago but I guess it slipped through the cracks. FreeBSD removed it in 2002: https://cgit.freebsd.org/src/commit/?id=e1d970f1811e5e1e9c912c032acdcec6521b2a6d NetBSD and DragonflyBSD can probably remove it, too. We export tickadj via the kern.clockrate sysctl(2), so update sysctl.2 and sysctl(8) accordingly. Hypothetically this change could break someone's sysctl(8) parsing script. I don't think that's very likely. ok mvs@

* Link pflog(4) instances to `pflog_ifs' list instead of allocatingmvs2021-01-132-52/+31
| | | | | | | | | | | | `pflogifs' array. This was done to prevent panics caused by internal malloc(9) limit. Also we avoid the case while single pflog(4) interface with a high index allocates an array for all indices below and eats up kernel memory. Since we have a very little count of pflog(4) interfaces linear search does not performance impact. ok bluhm@ claudio@ kn@
* Send without kernel lockkn2021-01-131-10/+7

* When an endpoint stalls, we usually try to reset it by callingmglocker2021-01-111-2/+2
| | | | | | | | | | | | usbd_clear_endpoint_stall(), which in turn will call usbd_clear_endpoint_toggle(). It can be a common situation that when this happens, there is still a transfer in the stalled queue being in progress. The ehci(4) clear toggle function is currently doing a panic() in the diagnostic code in this situation, which is a bit of an overkill. The device still can be recovered by detaching/attaching it. Therefore change the panic() in to a printf(). ok mpi@
* Simplify sleep signal handling a bit by introducing sleep_signal_check().claudio2021-01-112-19/+26

* Create a path MTU host route for IPsec over IPv6. Basically thebluhm2021-01-117-32/+111
| | | | | | | | | | | | | | | | code is copied from IPv4 and adapted. Some things are changed in v4 to make it look similar. - ip6_forward increases the noroute error counter, do that in ip_forward, too. - Pass more specific sockaddr_in6 to icmp6_mtudisc_clone(). - IPv6 may also use reject routes for IPsec PMTU clones. - To pass a route_in6 to ip6_output_ipsec_send() introduce one in ip6_forward(). That is the same what IPv4 does. Note that dst and sin6 switch roles. - Copy comments from ip_output_ipsec_send() to ip6_output_ipsec_send() to make code similar. - Implement dynamic IPv6 IPsec PMTU routes. OK tobhe@
