The language at http://tools.ietf.org/html/rfc7530#section-16.10.4 isn't as clear as it could be, but I think INVAL at least is unambiguously wrong in the case you're testing (it should be BAD_RANGE or OK). My interpretation is actually that we should return: - INVAL for 64-bit overflow, otherwise - BAD_RANGE for 32-bit overflow on 32-bit server, otherwise - OK for ranges that extend past FATTR4_MAXFILESIZE. (You're allowed to lock ranges not in the file.) So I prefer the test as-is, but might be open to argument about whether this is the most important case to be testing. --b. > > Signed-off-by: Tigran Mkrtchyan <tigran.mkrtchyan@xxxxxxx> > --- > nfs4.0/nfs4lib.py | 6 ++++++ > nfs4.0/servertests/st_lock.py | 3 ++- > 2 files changed, 8 insertions(+), 1 deletion(-) > > diff --git a/nfs4.0/nfs4lib.py b/nfs4.0/nfs4lib.py > index 5031feb..41870dc 100644 > --- a/nfs4.0/nfs4lib.py > +++ b/nfs4.0/nfs4lib.py > @@ -587,6 +587,12 @@ class NFS4Client(rpc.RPCClient, nfs4_ops.NFS4Operations): > d = self.do_getattrdict([], [FATTR4_LEASE_TIME]) > return d[FATTR4_LEASE_TIME] > > + def getMaxFileSize(self): > + """Get maximum supported file size""" > + d = self.do_getattrdict([], [FATTR4_MAXFILESIZE]) > + return d[FATTR4_MAXFILESIZE] > + > + > def create_obj(self, path, type=NF4DIR, attrs={FATTR4_MODE:0755}, > linkdata="/etc/X11"): > if __builtins__['type'](path) is str: > diff --git a/nfs4.0/servertests/st_lock.py b/nfs4.0/servertests/st_lock.py > index d54614d..80518f4 100644 > --- a/nfs4.0/servertests/st_lock.py > +++ b/nfs4.0/servertests/st_lock.py > @@ -189,8 +189,9 @@ def testLenTooLong(t, env): > """ > c = env.c1 > c.init_connection() > + max_size = c.getMaxFileSize(); > fh, stateid = c.create_confirm(t.code) > - res = c.lock_file(t.code, fh, stateid, 100, 0xfffffffffffffffe) > + res = c.lock_file(t.code, fh, stateid, 100, max_size) > check(res, NFS4ERR_INVAL, "LOCK with offset+len overflow") > > def testNoFh(t, env): > -- > 2.5.0 -- To unsubscribe from this list: send the line "unsubscribe linux-nfs" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
