>Description:

Recently (within the last week) compat_netbsd32 on amd64 broke. This is
from trying to exec a i386 tcsh in a i386 chroot on an amd64 machine running
-current as of a few hours ago:

 26296  26296 tcsh     CALL  netbsd32___sigprocmask14(1,0xfff9a2f4,0xfff9a2e4)
 26296  26296 tcsh     RET   netbsd32___sigprocmask14 0
 26296  26296 tcsh     CALL  netbsd32___sigsuspend14(0xfff9a304)
 26296  26296 tcsh     RET   netbsd32___sigsuspend14 -1 errno 4 Interrupted system call
 26296  26296 tcsh     PSIG  SIGCHLD caught handler=0x808bace mask=(2,20): code=CLD_EXITED child pid=15948, uid=0,  status=0, utime=0, stime=0)
 26296  26296 tcsh     CALL  compat_16_netbsd32___sigreturn14(0xfff9a260)
 26296  26296 tcsh     RET   compat_16_netbsd32___sigreturn14 -1 errno 78 Function not implemented
 26296  26296 tcsh     PSIG  SIGSYS SIG_DFL: code=SI_NOINFO
 26296  26296 tcsh     NAMI  "tcsh.core"


The same works on aarch64, both tcsh binaries are a bit oldish, both (base)
userlands are up to date (as of a few hours ago):

tcsh: ELF 32-bit LSB executable, Intel 80386, version 1 (SYSV), dynamically linked, interpreter /usr/libexec/ld.elf_so, for NetBSD 9.99.82, stripped
tcsh: ELF 32-bit LSB executable, ARM, EABI5 version 1 (SYSV), dynamically linked, interpreter /usr/libexec/ld.elf_so, for NetBSD 9.99.80, compiled for: earmv7hf, stripped

 Should we have this commit (and NFC style fixes in rev 1.6) for
 NetBSD 10.1? Or leave as is until PR 58225 and 58746 are fixed?

 Thanks,
 rin

 So I vote for fixing i386 compat binaries at least as you suggested.

 Sorry for the late response, and thanks for comment!

 I've filed [pullup-10 #989] COMPAT_NETBSD32: Fixes for signal handling 
 (kern/58215).

 Thanks,
 rin

 Pullups for this are easy and work, but it would be better to have
