Subject: fcntl(..,F_SETLK,..) over NFS fails on 2.2.5-15
Date: 27 May 1999 16:51:45 -0400
Hi,
I am not sure how/why, but fcntl() locks of files on NFS mounted
file systems fails with 2.2.5-15. It works on 2.0.34 (and other
OSs such as freeBSD, so I suspect this is something to do with
the 2.2 version. Here's a small sample program, (originally from
nmh-0.27-* (sbr/lock_file.c)), to illustrate the problem.
The machine runs stock redhat 6.0, and is
kannanvpc snippets$ uname -a
Linux kv 2.2.5-15 #3 Tue May 25 10:56:10 EDT 1999 i686 unknown
Has anyone else seen this before?
I wonder if this is a bug in the 2.2 kernels, my configuration
(I am also appending my kernel .config file at the bottom), or
something with the redhat 6.0 configuration.
Hopefully, someone can spot what I am missing in this?
Thanks,
Kannan
PS: Is there an appropriate place to posit kernel related bugs/issues?

One of the coolest things about Unix is its I/O redirection.
Couple that with several specialized utilities, and now you're
talking power.
One way to solve your problem is by using the 'wc' utility.
It counts not only words, but bytes or lines, too. So
$ grep /pattern/ foo.bar | wc -l
says to have grep send the lines that match /pattern/ to the
standard input of wc, which counts the number of lines when given
the '-l' option. Probably there is an option to grep which
does this too, but I think it's much simpler to learn a few
basic commands and hook them together.
If you want the output directed to foo.out just
$ grep /pattern/ foo.bar | wc -l > foo.out
If you don't like the format of wc's output, you can use sed, awk,
or perl, or put the commands into a shell script, to strip/add spaces,
insert text, etc.. But don't stop there. Learn Tcl/Tk, or use
PerlWish or Perl/Tk, and add a graphical interface.
Flexibility. Power. That's what I'm talking about...

Have you tried fscking the drive? Bring the system up under the install
bootdisk, go to one of the terminals that has a shell running(there should be
at least one), then run:
fsck -b 8193 /dev/hda1
Replace hda1 with your partition. It should be able to fix all the problems
on the drive.

Subject: GNU libtool 1.3.2 released
Date: 27 May 1999 11:55:24 -0300
Dear developers,
Just after release 1.3 of GNU libtool, we were flooded with bug
reports about a security problem in the libtool installation: the
directory $prefix/share/libtool/libltdl would be installed with mode
777. :-( Furthermore, developers started to complain about weird
autoconf errors, caused by a typo in libtool.m4, that would show up
only for *some* `configure.in's. :-(
GNU libtool 1.3.1 was never released, because we found a few critical
portability problems just before announcing it.
These and a few other portability problems have been fixed in release
1.3.2. Unfortunately, at the time of this writing, we've already
found out one more, that causes -export-symbols-regex to fail when
creating a libtool library linked with libtool convenience libraries.
If you need this feature, you may want to get a CVS snapshot from the
release branch (-r branch-1-3). Instructions are available at our
home page: <URL:http://www.gnu.org/software/libtool/libtool.html>
If you have already upgraded to libtool 1.3, we urge you to upgrade to
at least libtool 1.3.2, or at least to chmod the directory containing
libltdl so that it is not world-writable.
The list of user-visible changes since release 1.3 follows:
New in 1.3.2: 1999-05-26, CVS version 1.3.1a, Libtool team:
* Avoid circular links of objects and libraries.
* Look for dlerror when dlopen was found in -ldl (typo).
* Disable shared libraries with broken GNU ld on Solaris.
* Documentation improvements; recommend automake users to insert libtool.m4
in acinclude.m4
* AC_LIBLTDL_CONVENIENCE and AC_LIBLTDL_INSTALLABLE now set INCLTDL.
* New port to NEC UX/4800.
* cygwin-b20.1 passes all tests.
* Slightly improved BeOS support.
* Many AIX 4.3.2 test failures have gone.
