I'm a bit puzzled by this. On my 4.1-STABLE box, it appears to correctly
return EOPNOTSUPP in the simplist invocation:
> cat > tmp.c
#include <sys/types.h>
#include <sys/acl.h>
int
main(int argc, char *argv[])
{
acl_t acl;
int error;
acl = acl_get_file("/bin/sh", ACL_TYPE_ACCESS);
if (error)
perror("acl_get_file");
}
> gcc -o tmp tmp.c -lposix1e
> ./tmp
acl_get_file: Operation not supported
Which is the correct behavior, as none of the base file systems currently
defines ACL functionality. The same should occur for acl_check_file() and
acl_set_file(). I haven't tried this on 5.0-CURRENT recently, but
vop_panic() should only be invoked when there is an attempt to call slot 0
of the VOP table for the file system. Slot 1, the default slot, should
return EOPNOTSUPP.
It looks like you attempted to invoke acl_get_file() much as above. Are
you using any file system modules, and what file system was the target of
acl_get_file() in? Could it be the case that your modules are out of
sync with your kernel? (Not that I'd hope this was the result, but...)
