I'm trying to run a SCO SVR4 executable on FreeBSD but I get a SIGSYS
(invalid system call) at the very beginning. Here is the kdump:
39525 ktrace RET ktrace 0
39525 ktrace CALL sigprocmask(0x1,0x28061000,0x28061010)

39525 ktrace CALL sigprocmask(0x3,0x28061010,0)
39525 ktrace RET sigprocmask 0
39525 ktrace CALL execve(0xbfbff9a3,0xbfbff880,0xbfbff88c)
39525 ktrace NAMI "./scobin"

39525 scobin RET break 0

39525 scobin RET setlogin 0
39525 scobin CALL getpid
39525 scobin RET getpid 39525/0x9a65
39525 scobin CALL old.lstat
39525 scobin PSIG SIGSYS SIG_DFL
39525 scobin NAMI "scobin.core"
Which call is it about? I see an "old.lstat" but I couldn't find any
reference in the kernel source tree. Is there any doc I could read to
see if I can hack this syscall in the emulator?
Thanks,
