2024-04-05On machines lacking xonly support hardware, we emulate xonly in theTheo de Raadt
copyin(9) layer below system calls, using a 4-entry lookup; the 4th entry is libc.so text. We were assuming, or rather insisting, that on all our architectures libc.so text is treated as xonly, even if the linker was behind in it's game. Since msyscall(2) is gone, kernel no longer has information about the start,len of libc.so text segment. But we can instead use the (same) start,len range of pinsyscalls() instead for this purpose. ld.so is passing the same text-range to the kernel in this position. regression tests run by anton discovered that libc.so text had become copyin-readable. ok kettenis
2024-04-05Esure the base,len range provided by ld.so is definately in the map.Theo de Raadt
Being outside the map doesn't seem like it can do anything bad. Discussed with kettenis

ok mpi@
2024-04-03Initialize earlier macppc's and powerpc64's pmap_hash_lockGeorge Koehler
At boot, the powerpc64 kernel was calling pmap_bootstrap -> pmap_kenter_pa -> mtx_enter(&pmap_hash_lock) before it did pmap_init -> mtx_init(&pmap_hash_lock, IPL_HIGH) Change from mtx_init to MUTEX_INITIALIZER. This allows an option WITNESS kernel to boot without warning of an uninitialized mutex. Also change macppc's pmap_hash_lock from __ppc_lock_init to PPC_LOCK_INITIALIZER, though WITNESS doesn't see this lock. ok mpi@

2024-04-03Reuse the timeout from struct scsi_xfer rather than declaring one inMiod Vallat
struct ncr53c9x_ecb. When the scsi_xfer timeout was introduced *cough* 23 years ago, SCSI drivers were progressively updated to use this, but for some reason that driver got missed. ok dlg@ krw@
2024-04-03Change ipmi(4)'s taskq from IPL_NONE to IPL_MPFLOORGeorge Koehler
The IPL_NONE mutex didn't block interrupts that can cause a powerpc64 kernel with option WITNESS to "panic: acquiring blockable sleep lock with spinlock or critical section held (kernel_lock) &kernel_lock". ok mpi@
2024-04-03Add ci_cpuid_level and ci_vendor holding the per-CPU basic cpuidPhilip Guenther
level and a numeric mapping of the cpu vendor, both from CPUID(0). Convert the general use of strcmp(cpu_vendor) to simple numeric tests of ci_vendor.

2024-04-02Delete the msyscall mechanism entirely, since mimmutable+pinsyscalls hasTheo de Raadt
replaced it with a more strict mechanism, which happens to be lockless O(1) rather than micro-lock O(1)+O(log N). Also nop-out the sys_msyscall(2) guts, but leave the syscall around for a bit longer so that people can build through it, since ld.so(1) still wants to call it.

2024-04-01Delete 108 lines of ASM from vmx_enter_guest() that predated lotsPhilip Guenther
of later enhancements, removing the save/restore of flags, selectors, and MSRs: flags are caller-saved and don't need restoring while selectors and MSRs are auto-restored. The FSBASE, GSBASE, and KERNELGSBASE MSRs just need the correct values set with vmwrite() in the "on new CPU?" block of vcpu_run_vmx(). Also, only rdmsr(MSR_MISC_ENABLE) once in vcpu_reset_regs_vmx(), give symbolic names to the exit-load MSR slots, eliminate VMX_NUM_MSR_STORE, and #if 0 the vc_vmx_msr_entry_load_{va,pa} code and definitions as unused. ok dv@
2024-03-31Enable rge(4).Mark Kettenis
2024-03-31Combine route_cache() and rtalloc_mpath() in new route_mpath().Alexander Bluhm
Fill and check the cache and call rtalloc_mpath() together. Then the caller of route_mpath() does not have to care about the uint32_t *src pointer and just pass struct in_addr. All the conversions are done inside the functions. A previous version of this diff was backed out. There was an additional rtisvalid() in rtalloc_mpath() that prevented packet output via interfaces that were not up. Now the route in the cache has to be valid, but after new lookup, rtalloc_mpath() may return invalid routes. This generates less errors in userland an preserves existing behavior. OK sashan@
2024-03-31Allow listen(2) only on sockets of type SOCK_STREAM or SOCK_SEQPACKET.Vitaliy Makkoveev
listen(2) man(1) page clearly prohibits sockets of other types. Reported-by: syzbot+00450333592fcd38c6fe@syzkaller.appspotmail.com ok bluhm
2024-03-31Mark `so_rcv' sockbuf of udp(4) sockets as SB_OWNLOCK.Vitaliy Makkoveev
sbappend*() and soreceive() of SB_MTXLOCK marked sockets uses `sb_mtx' mutex(9) for protection, meanwhile buffer usage check and corresponding sbwait() sleep still serialized by solock(). Mark udp(4) as SB_OWNLOCK to avoid solock() serialization and rely to `sb_mtx' mutex(9). The `sb_state' and `sb_flags' modifications must be protected by `sb_mtx' too. ok bluhm

2024-03-30Prevent a recursion inside wakeup(9) when scheduler tracepoints are enabled.Martin Pieuchot
Tracepoints like "sched:enqueue" and "sched:unsleep" were called from inside the loop iterating over sleeping threads as part of wakeup_proc(). When such tracepoints were enabled they could result in another wakeup(9) possibly corrupting the sleepqueue. Rewrite wakeup(9) in two stages, first dequeue threads from the sleepqueue then call setrunnable() and possible tracepoints for each of them. This requires moving unsleep() outside of setrunnable() because it messes with the sleepqueue. ok claudio@
