2.4.19 NFS file perms

[Richard Zidlicky <rz@linux-m68k.org>]

Hi,

on an NFS mounted fs, executing as root I see this:

[root@sirizidl nfsr]# ll /nfsr/toplev.fig 
-rw-------    1 kernel   users       48500 Oct  5 11:42 /nfsr/toplev.fig
[root@sirizidl nfsr]# xfig /nfsr/toplev.fig 
[snip]
...
stat64("toplev.fig", {st_mode=S_IFREG|0600, st_size=48500, ...}) = 0
open("toplev.fig", O_RDONLY)            = 4
fstat64(4, {st_mode=S_IFREG|0600, st_size=48500, ...}) = 0
old_mmap(NULL, 48500, PROT_READ, MAP_PRIVATE, 4, 0) = 0xc0011000
read(4, 0xefffe4cb, 1)                  = -1 EIO (Input/output error)
_llseek(4, 48500, [48500], SEEK_SET)    = 0
--- SIGBUS (Bus error) ---

glibc crashes in fgets because it doesn't expect the problem after the 
file has been successfully opened and mapped.. who is at fault here?

Remote nfs server is an old userspace implementation btw.
