p.s. there are those who:
a. make things happen
b. watch things happen
c. wonder what happened..
and .. perhaps related to b., and particularly apropos to Usenet..
d. interfere/complain/criticise/oppose/flame what is happening..

Subject: v2.2.5+, fcntl locking of file on an NFS mounted partition fails
Date: 10 Jun 1999 15:52:48 -0400
Hi,
I am trying to lock files that exist on an NFS mounted partition
using the fcntl() system call as:
fcntl(fd, F_RDLCK, { F_RDLCK, SEEK_SET, 0, 0})
or fcntl(fd, F_WRLCK, { F_WRLCk, SEEK_SET, 0, 0})
I get 'No locks available' when I do this. My machine is:
% uname -a
Linux
kannanvpc.research.bell-labs.com
2.2.5-15 #2 Fri Jun 4 17:02:59 EDT 1999
i686
unknown
I see this both with the stock 2.2.5 kernel that was distributed in
redhat6.0, as well as with the 2.2.9 kernel. I did not see this
problem in 2.0.* kernels.
I see this problem with NFS servers on freebsd 3.1 machines, or
netapps (of unknown pedigree). This problem happens often, because
the default configuration for the nmh anno(tate) program is to
use fcntl locking.
I am not really sure what I am doing wrong, or how this would get fixed.
I have turned on (some) detailed traces of the lock code, and stared at
some tcp dump traces, but they are meaningless to me. I am including
portions of the log from my turning on debugging, the sample program I
used to illustrate the problem, tcpdump traces when I use the program,
as well as my kernel config.
Thoroughly puzzled at this stage, and glad for any concrete suggestions
or fixes -- Kannan
1. In conjunction with the locking failing, I also kept seeing:
lockd: failed to monitor 135.104.27.216
To get additional traces, I turned on tracing in the locking and
sunrpc code: specifically, I had
nlm_debug = NLMDBG_CLIENT|NLMDBG_MONITOR;
rpc_debug = RPCDBG_CALL|RPCDBG_XPRT;
in fs/lockd/clntproc.c:nlmclnt_lock(). The trace of a typical lock
operation then is:

2. Funnily enough, when I use tcpdump to trace traffic, I see no RPC
calls to the remote host, associated with the file locking. I see
NFS calls, and responses, but no locking calls. Here's a small test
program that does does the file creation, write a small piece of
data, and attempt to lock it (This file is copied a minor variant of
the lock_file.c from the nmh-0.27 sources):
/*
* lock.c -- routines to lock/unlock files
*
* $Id$
*/
#include <stdio.h>
#include <sys/types.h>
#include <stdlib.h>
#include <unistd.h>
#include <string.h>
# include <errno.h>
# include <fcntl.h>
static void testLock(char*, int);
int
main(int argc, char* argv[])
{
int fd;
char* file = (argc >= 2 ? argv[1] : "./test");
/* create the file */
fd = open(file, O_RDWR|O_CREAT, 0644);
if (fd < 0) {
perror("write");
return EXIT_FAILURE;
}
(void) write(fd, "TEST", 5);
(void) close(fd);
testLock(file, O_RDONLY);
testLock(file, O_RDWR);
(void) unlink(file);
return EXIT_SUCCESS;
}
static void
testLock(char *file, int access)
{
int fd, j;
struct flock buf;
/* make sure we open at the beginning */
access &= ~O_APPEND;
if ((fd = open (file, access | O_NDELAY)) == -1) {
fprintf(stderr, "open(%s): %s", file, strerror(errno));
return;
}
buf.l_type = (((access & O_WRONLY) || (access & O_RDWR)) ?
F_WRLCK : F_RDLCK);
buf.l_whence = SEEK_SET;
buf.l_start = 0;
buf.l_len = 0;
j = fcntl (fd, F_SETLK, &buf);
if (j < 0) {
fprintf(stderr,
"fcntl(%s(fd = %d), F_SETLK, {%s, SEEK_SET, 0, 0}) = %s\n",
file, fd,
(buf.l_type == F_RDLCK ? "F_RDLCK" : "F_WRLCK"),
strerror(errno));
} else {
fprintf(stderr,
"fcntl(%s(fd = %d), F_SETLK, {%s, SEEK_SET, 0, 0}) = %s\n",
file, fd,
(buf.l_type == F_RDLCK ? "F_RDLCK" : "F_WRLCK"),
"success");
buf.l_type = F_UNLCK;
buf.l_whence = SEEK_SET;
buf.l_start = 0;
buf.l_len = 0;
fcntl(fd, F_SETLK, &buf);
}
close (fd);
return;
}
3. Here's a trace of traffic when this code is executed:

(So, there's the lookup -> create -> write and lookup -> remove
sequences between the two hosts.)
