Hello, I'm using samba 4.7.3 to run an AD and I'm currently having issues with the MIT kerberos because it stops some time after starting (and apparently working correctly) without logging nothing out of the ordinary. My setup has 2 DC: one in an ubuntu 12.04 with version 4.1.9 (which we're migrating from) and the one I mentioned in CentOS 7 (which will be the only DC in the future).

F_SETFD takes an "int", so it stands to reason that FD_CLOEXEC expands to an "int". In turn, it's bad hygiene to manipulate the sign bit of (signed) integers with bit operations: ~FD_CLOEXEC Convert FD_CLOEXEC to "unsigned int" for the bitwise complement operator: ~...

The previous code: fcntl (fd, F_SETFL, O_NONBLOCK) was technically incorrect, because it would have reset any other flags on the file descriptor.

I'm trying to test a trivial patch to set FD_CLOEXEC on the flintlock lockfd when using F_OFD_SETLK and am running into a build failure even in an unpatched state. This is on a Debian jessie amd64 system building the jessie-backports version. The stable version (1.2.19-1+deb8u1) works and builds fine using the same commands, however I also encountered a similar build problem in a sid chroot
