2022-02-22Since other exported commandnames were increased to 24 and graduated intoTheo de Raadt
proper strings, adapt dt's exported string in the same way. Old/new files/tools will not work the same way. That this interface needs to also change was pointed out by jsg
2022-02-22Since other exported commandnames were increased to 24 and graduated intoTheo de Raadt
proper strings, adapt struct acct's ac_comm similarily. While here increase ac_mem to 32-bits, increase ac_flag from 8 to 32 bits for future extensions, add ac_pid for forensics, and reorder the structure to avoid compiler pads. More work remains in the sa(8) command to use ac_pid better. This is a flag day for the acct file format, new/old files/tools are incompatible. ok bluhm millert
2022-02-22Start using new _MAXCOMLEN (a proper string expanded to 24 bytesTheo de Raadt
including the NUL), in all internal interafaces, and expose this in ktrace, core, or proc.h visibility. ok millert
2022-02-22sysctl already passed the commandname as a 24-byte string KI_MAXCOMLENTheo de Raadt
because it was padded. Define it in terms of _MAXCOMLEN from syslimits.h ok millert
2022-02-22Define MAXCOMLEN in terms of _MAXCOMLEN (-1, because MAXCOMLEN does notTheo de Raadt
have the terminating NUL). In the near future, fewer programs will use this yucky non-string, some kernel:userland interfaces will to change to pass a proper string. ok millert
2022-02-22Add _MAXCOMLEN to syslimits, it is 24, and includes the NUL. FollowingTheo de Raadt
commits will change sys/param.h MAXCOMLEN, sys/sysctl.h KI_MAXCOMLEN, sys/acct.h ac_comm[], dev/ic/dtvar.h DTMAXCOMLEN to use this, and also adapt most to the included NUL correctly. This will allow us to remove sys/param.h include from userland base. sys/syslimits.h is chosen as the best place for this define because it has very small namespace which is already pulled in often. ok millert

No functional change.
2022-02-22Clear frame pointer in cpu_fork() on riscv64Visa Hankala
This ensures the chain of call frames is terminated properly, preventing errors when unwinding kernel stacks. OK miod@ kettenis@
2022-02-22ddb: Improve stack unwinding on riscv64Visa Hankala
Add logic to navigate across trapframes. Stop unwinding if the frame pointer is clearly bad. Adjust output, and tweak details. OK miod@ kettenis@
2022-02-22Make audio(4) event filters MP-safeVisa Hankala
Add f_modify and f_process callbacks, and initialize the knote lists to use audio_lock. This makes audio_lock cover the device's knote processing. OK mpi@
2022-02-22The FILL_KPROC() macro should be useable in situations where sys/param.hTheo de Raadt
hasn't been included, so the use of MIN() is not legit, and a local version is required.

2022-02-21Grab vmobjlocks with RW_DUPOK in vm_obj_wire() to silence WITNESSKlemens Nanni
The drm subsystem implements graphics buffers as uvm objects backed by anonymous memory, thus drm locks and aobj locks share the same "vmobjlock" type. uvm_obj_wire() is only called from sys/dev/pci/drm/, so instead of changing drm's lock init/alloc routines to mark allow duplicate locks in general, enter uvm's vmobjlock with RW_DUPOK in this function to allow duplicate lock types per thread in this specific call path alone. Fixes the following WITNESS report when booting/starting X (as seen already in other unrelated bugs@ reports): wsdisplay0: screen 1-5 added (std, vt100 emulation) witness: acquiring duplicate lock of same type: "&uobj->vmobjlock" 1st uobjlk 2nd uobjlk Starting stack trace... witness_checkorder(fffffd83b625f9b0,9,0) at witness_checkorder+0x8ac rw_enter(fffffd83b625f9a0,1) at rw_enter+0x68 uvm_obj_wire(fffffd843c39e948,0,40000,ffff800033b70428) at uvm_obj_wire+0x46 shmem_get_pages(ffff800008008500) at shmem_get_pages+0xb8 __i915_gem_object_get_pages(ffff800008008500) at __i915_gem_object_get_pages+0x6d i915_gem_fault(ffff800008008500,ffff800033b707c0,10009b000,a43d6b1c000,ffff800033b70740,1,35ba896911df1241,ffff8000000aa078,ffff8000000aa178) at i915_gem_fault+0x203 drm_fault(ffff800033b707c0,a43d6b1c000,ffff800033b70740,1,0,0,7eca45006f70ee0,ffff800033b707c0) at drm_fault+0x156 uvm_fault(fffffd843a7cf480,a43d6b1c000,0,2) at uvm_fault+0x179 upageflttrap(ffff800033b70920,a43d6b1c000) at upageflttrap+0x62 usertrap(ffff800033b70920) at usertrap+0x129 recall_trap() at recall_trap+0x8 end of kernel end trace frame: 0x7f7ffffdc7c0, count: 246 End of stack trace.
