2022-12-08Forcibly set console output to the framebuffer on the Lenovo x13s.Patrick Wildt
We should actually do something like checking that both stdout-path and serial0 don't exist to realize we have to switch, but this hack gets us going for now. ok kettenis@

2022-12-07Do not store unused ICMPv6 Option PREFIX_INFORMATIONKlemens Nanni
Dead since 2017 sys/netinet6/nd6_rtr.c r1.163 Remove sending of router solicitations and processing of router advertisements from the kernel. It's handled by slaacd(8) these days. sysctl(2) net.inet6.icmp6.nd6_debug does not warn about it like it does for, e.g., duplicate MTU options, so don't do anything with this option. Remove access macros for other unused options while here. Eventually, union nd_opts should be removed completely. All under _KERNEL. tcpdump(8)/rad(8)/slaacd(8) keep showing/sending/receiving this option when running this diff on both router and client. OK claudio

2022-12-06i386: switch to clockintrScott Soule Cheloha
In lapic timer mode: - Rip out lapic_delay(). We can't use the lapic timer to delay(9) when it's running in one-shot mode. - Add a randomized statclock(), stathz = hz. - Add profiling support, profhz = stathz * 10. - Wire up lapic_intrclock. In i8254-mode: - i8254's clockintr() does not have a monopoly on hardclock(9). - mc146818's rtcintr() does not have a monopoly on statclock(). - In profiling mode, the statclock() will drift very slightly because (profhz = 1024) does not divide into 1 billion. Need to consider how best to fix this. ACPI suspend/resume tested by mlarkin@ via ESXi. Tons of testing by Scott Bennett on a Pentium 4 machine; APM suspend/resume confirmed to work there, too.

2022-12-06m88k, luna88k: switch to clockintrScott Soule Cheloha
- Initialize tick_nsec during cpu_initclocks() We have no control over the interrupt clock on luna88k, so this switch is trivial. Bringup help and testing from aoyama@ and miod@. Link: https://marc.info/?l=openbsd-tech&m=166776371203450&w=2 ok aoyama@ mlarkin@
2022-12-06hppa: switch to clockintrScott Soule Cheloha
- Remove hppa-specific clock interrupt scheduling bits from cpu_info. - Rename cpu_hardclock() to itmr_intr(); it doesn't exclusively run hardclock(9) anymore. - Wire up itmr_intrclock. hppa now has a randomized statclock(), stathz = hz. Patch help, testing, and review from kettenis@ (B2000) and miod@ (C3650). MP testing from guenther@ (dual-core J6700). ok mlarkin@ kettenis@, "Ship it?" guenther@

2022-12-02Remove constant basereachable and retrans members from struct nd_ifinfoKlemens Nanni
Both are initalised with compile-time constants and never written to. They are part of the Neighbour Discovery machinery and only surface through the single-user SIOCGIFINFO_IN6: $ ndp -i lo0 basereachable=30s0ms, reachable=39s, retrans=1s0ms These values are read-only since 2017 sys/netinet6/nd6.c r1.217 usr.sbin/ndp/ndp.c r1.85 Remove knob and always do neighbor unreachable detection Inline the macros (to keep meaningful names), shrink the per-interface allocated struct nd_ifinfo to what is actually needed and inline nd6_dad_starttimer()'s constant `msec' argument. Nothing else in base, incl. regress, uses SIOCGIFINFO_IN6 or `ndp -i'. OK bluhm
2022-12-02Remove useless variable, simplify codeKlemens Nanni
Using a local `duplicate' variable to defer the actual checks by a few lines, interleaved with comments (saying the same thing but negated), is harder to follow that neccessary. Fold the logic and merge comments (remove the last obvious one missing a negation) to save 20 LOC. OK bluhm
2022-12-02Unlock in6_ioctl_get() aka. SIOCGIF{DSTADDR,NETMASK,AFLAG,ALIFETIME}_IN6Klemens Nanni
First the right address is picked from the net lock protected if_addrlist. Then all ioctls just copy out the address, nothing requires the kernel lock. SIOCGIFDSTADDR_IN6 checks the net lock protected if_flags, SIOCGIFALIFETIME_IN6 computes lifetimes which only need the address. This removes the last kernel lock from IPv6 read ioctls (multicast being the untouched exception here). Users of these ioctl(2)s are route6d(8), rad(8), slaacd(8), isakmpd(8) and of course ifconfig(8). OK mvs

2022-11-30Unlock nd6_ioctl(), push kernel lock into in6_ioctl_{get,change_ifaddr}()Klemens Nanni
Neighbour Discovery information is protected by the net lock, as documented in nd6.h struct nd_ifinfo. ndp(8) is the only SIOCGIFINFO_IN6 and SIOCGNBRINFO_IN6 user in base. nd6_lookup(), also used in ICMP6 input and IPv6 forwarding, only needs the net lock. OK mvs
2022-11-30Use shared socket/net lock for IP socketsKlemens Nanni
so{,un}lock_shared() take the shared net lock for PF_INET and PF_INET6 while sticking to the exclusive rwlock elsewhere. getsockopt(2), getsockname(2) and getpeername(2) (all UNLOCK) do not write, so the exclusive net lock is overkill here. OK mvs
2022-11-30regenVitaliy Makkoveev
2022-11-30Unlock getsockopt(2) and setsockopt(2). Unlock them both because atVitaliy Makkoveev
protocol layer they follow the same (*pr_ctloutput)() handlers. At sockets layer we touch only per-socket data, which is solock() protected. At protocol layer, udp(4), unix(4) and key management sockets have no (*pr_ctloutput)() handlers. route_ctloutput() touches only per socket data, which is solock() protected. inet{,6} globals are protected by netlock, which is solock() backend for corresponding sockets. ok bluhm@
