2023-12-12ibuf_getdata() abuses the rpos from the ibuf. This is no longer allowedClaudio Jeker
and breaks because ibuf_seek() now uses rpos itself. Now this is just ibuf_get_ibuf() with an extra allocation done. OK tobhe@ tb@

2023-12-12Extend imsg and ibuf API with useful getter methodsClaudio Jeker
For ibufs: - various getters for ibufs (ibuf_get* and ibuf_skip) - additional ibuf set/add functions that don't alter byte order - ibuf_truncate and ibuf_rewind - ibuf_from_buffer and ibuf_from_ibuf to populate a reader ibuf - a getter for the msgbuf queuelen For imsg: - various getters for imsg (especially imsg_get_data() which can be used in most cases as a simple one call api with all error checks). All the imsg.hdr fields can also be accessed by getters. - The imsg data is now actually an ibuf but the old imsg.data pointer is kept for now to not break every imsg application. - Introduce imsg_forward to simply forward a message from one channel to an other (used in the control socket code). Since this requires a major bump take the oportunity to also cleanup some function signatures to use size_t for length fields. Also internal data structures are removed from the public header.

2023-12-12To avoid kbind(2) becoming a powerful gadget, it is called inline to aTheo de Raadt
function. Therefore we cannot create a precise pinsyscall label. Instead create a duplicate entry (using inline asm) to force the kernel's pinsyscall code to skip validation, rather than labelling it illegal. kbind(2) remains safe because it self-protects by checking its calling address. ok kettenis

2023-12-12syncTheo de Raadt
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?

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@

2023-12-11Turn `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@
