2023-12-12remove support for syscall(2) -- the "indirection system call" becauseTheo de Raadt
it is a dangerous alternative entry point for all system calls, and thus incompatible with the precision system call entry point scheme we are heading towards. This has been a 3-year mission: First perl needed a code-generated wrapper to fake syscall(2) as a giant switch table, then all the ports were cleaned with relatively minor fixes, except for "go". "go" required two fixes -- 1) a framework issue with old library versions, and 2) like perl, a fake syscall(2) wrapper to handle ioctl(2) and sysctl(2) because "syscall(SYS_ioctl" occurs all over the place in the "go" ecosystem because the "go developers" are plan9-loving unix-hating folk who tried to build an ecosystem without allowing "ioctl". ok kettenis, jsing, afresh1, sthen
2023-12-12slyle(9) fix. No functional changes.Vitaliy Makkoveev
2023-12-12The sigtramp was calling sigreturn(2), and upon failure exit(2), whichTheo de Raadt
doesn't make sense anymore. It is better to just issue an illegal instruction. ok kettenis, with some misgivings about inconsistant approaches between architectures. In the future we could change sigreturn(2) to never return an exit code, but always just terminate the process. We stopped this system call from being callable ages ago with msyscall(2), and there is no stub for it in libc.. maybe that's the next step to take?
2023-12-12Turn `pflowstats' statistics counters into per-CPU counters to make themVitaliy Makkoveev
mpsafe. The weird interactions around `pflow_flows' and `sc_gcounter' replaced by simple `pflow_flows' increment. Since the flow sequence is the 32 bits integer, the `sc_gcounter' type replaced by the type of uint32_t. ok bluhm sashan
2023-12-11Implement per-CPU caching for the page table page (vp) pool and the PTEMark Kettenis
descriptor (pted) pool in the arm64 pmap implementation. This significantly reduces the side-effects of lock contention on the kernel map lock that is (incorrectly) translated into excessive page daemon wakeups. This is not a perfect solution but it does lead to significant speedups on machines with many CPU cores. This requires adding a new pmap_init_percpu() function that gets called at the point where kernel is ready to set up the per-CPU pool caches. Dummy implementations of this function are added for all non-arm64 architectures. Some other architectures can probably benefit from providing an actual implementation that sets up per-CPU caches for pmap pools as well. ok phessler@, claudio@, miod@, patrick@
2023-12-11Fix the shift of status bits 2:0 to 11:9 from <<8 to <<9.Kenneth R Westerback

2023-12-11Turn `pflow_softc' list into SMR list.Vitaliy Makkoveev
Since the revision 1.1182 of net/pf.c netlock is not taken while export_pflow() called from pf_purge_states(). Current locks order requires netlock to be taken before PF_LOCK(), so there is no reason to turn it back into this path only for optional export_pflow() call. The `pflowif_list' foreach loop has no context switch within, so SMR list is better than mutex(9). Tested by Hrvoje Popovski. ok sashan bluhm

2023-12-10vmm(4): flush EPTs after enabling VMX mode.Dave Voutila
The Intel SDM states the vmxon/vmxoff instructions don't invalidate any EPT states on the cpu and recommend invalidating the global context. vmm(4) opportunistically disables and enables VMX mode as vms are created or terminated, so this adds a recommended housekeeping step per the SDM. While here, tidy up the CR4 toggling by moving it to after the MSR feature check. ok mlarkin@

2023-12-10Skip interfaces already claimed by other uaudio(4) instances.Alexandre Ratchov
Fixes support of devices that attach multiple uaudio(4) drivers. Every uaudio(4) instance parses the full set of device descriptors because there are multiple interfaces per driver instance. If there is a second uaudio(4) instance (i.e. a second control & stream interfaces combo), the latter must skip the interfaces already used by the first one (if it didn't, multiple uaudio(4) would try to use the same interface and neither would work).

2023-12-07Inpcb table mutex protects addr and port during bind(2) and connect(2).Alexander Bluhm
in_pcbbind(), in_pcbconnect(), and in6_pcbconnect() have to set addresses and ports within the same critical section as the inpcb hash table calculation. Also lookup and address selection have to be protected to avoid bindings and connections that are not unique. For that in_pcbpickport() and in_pcbbind_locked() expect that the table mutex is already taken. The functions in_pcblookup_lock(), in_pcblookup_local_lock(), and in_pcbaddrisavail_lock() grab the mutex iff the lock parameter is IN_PCBLOCK_GRAB. Otherwise the parameter is IN_PCBLOCK_HOLD has the lock has to be taken already. Note that in_pcblookup_lock() and in_pcblookup_local() return an inp with increased reference iff they take and release the lock. Otherwise the caller protects the life time of the inp. This gives enough flexibility that in_pcbbind() and in_pcbconnect() can hold the table mutex when they need it. The public inpcb API does not change. OK sashan@ mvs@

2023-12-07avoid bad register access in eephy_reset for Marvell Alaska 88E1512Uwe Stuehler
The register write before this change had no visible run-time effect on 88E1512 under normal conditions but it tried to update a reserved bit and might prevent the standard behaviour of breaking the link on insufficient Inter-Packet Gaps. Cross-checked with datasheets for supported variants. Extended special control register 20 exists only in E1111 but not in E151x, E1545x, or E3016. It seems that the register was dropped in E15xx and subsequent designs. Originally from stsp@ ok claudio@ stsp@
2023-12-06Protect socket receive buffer in IP multicast routing.Alexander Bluhm
Since soreceive() runs in parallel for raw sockets, sbappendaddr() has to be protected by inpcb mutex. This was missing in multicast forwarding which is running with a combination of shared net lock and kernel lock. soreceive() uses shared net lock and mutex per inpcb.

This avoids an intermediate link state (10baseT) before the interface is configured via ifconfig(8), and is consistent with other MII drivers and OSes. The original reason for this workaround is mainly thought be related to either reducing the time required for auto-negotiation to complete or indeed incorrect advertisement of link capabilities.
