CVS commit: src/sys/compat/netbsd32

["Simon Burge" <simonb%netbsd.org@localhost>]

Module Name:    src
Committed By:   simonb
Date:           Tue Jan 19 03:41:22 UTC 2021

Modified Files:
        src/sys/compat/netbsd32: netbsd32.h netbsd32_conv.h netbsd32_fs.c
            netbsd32_netbsd.c netbsd32_socket.c

Log Message:
The read/write/send/recv system calls return ssize_t because -1 is
returned on error.  Therefore we must restrict the lengths of any
buffers to NETBSD32_SSIZE_MAX with compat32 to avoid garbage return
values.

Fixes ATF lib/libc/sys/t_write:write_err.
