Windows share modes and Linux file locking, flock & fcntl
...start=256, len=1}, 0xbff6a890) = 0
open("temp/test.txt", O_RDWR|O_LARGEFILE) = 19
flock(19, 0x20 /* LOCK_??? */) = 0
fcntl64(19, F_SETSIG, 0x23) = 0
fcntl64(19, 0x400 /* F_??? */, 0x1) = 0
The second argument to flock() on the test file is 0x20, which is what
LOCK_MAND is defined as in the samba-3.0.28 source in the file
source/include/includes.h. This is the same value I find in
/usr/include/bits/fcntl.h and /usr/include/asm/fcntl.h.
So I wrote a test program (included below) that uses flock with this
value (instad of the usual LOCK_EX) but multiple instances...

blocking file locks
...ocks would work for them, and also they do not seem to be Linux-compatible
on the server, and I suspect I may need that for efficiency's sake (a lot of
files are being locked/unlocked). I downloaded samba-latest.tar.gz and
noticed that source/smbd/blocking.c seems to respond to these by setting
LOCK_MAND versions of flock states, which are available only for "sys_flock"
and rumored not to affect normal Linux programming.
Can file locks block a Samba open request? Can they be set by, or made to
affect, Linux programming on the server (I don't care about NFS file opens,
only local open...

oplocks, kernel oplocks, kernel share modes, .. - how it all works?
Hi!
I'm trying to understand how various ways to grant a file lease to (windows) clients
works. Especially in context when files are being modified locally on the linux
filesystem.
For example, there's this wording in man smb.conf:
kernel share modes
...
Kernel share modes provide a minimal level of interoperability with
local UNIX processes and NFS operations by

[klibc 00/31] klibc as a historyless patchset (updated and reorganized)
I have updated the klibc patchset based on feedback received. In
particular, the patchset has been reorganized so as not to break
git-bisect.
Additionally, this updates the patch base to 2.6.17-git12
(d38b69689c349f35502b92e20dafb30c62d49d63) and klibc 1.4.8; the main
difference on the klibc side is removal of obsolete code.
