[libnbd PATCH v3 13/29] socket activation: avoid manipulating the sign bit
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:
~(unsigned)FD_CLOEXEC
The bitwise complement then results in an &...

MIT Kerberos suddenly stopping
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).

[Bug 1104] New: Use close on exec flags instead of fcntl
...at lists.netfilter.org
Reporter: g.gupta at samsung.com
Now in lateswt versions of glibc, close on exec flags are available for
file/socket open functions which are better than using fcntl.
Below is current usage of fcntl in iptables:
./libxtables/xtables.c: if (fcntl(procfile, F_SETFD, FD_CLOEXEC) == -1) {
./libxtables/xtables.c: if (fcntl(sockfd, F_SETFD, FD_CLOEXEC) == -1) {
./libiptc/libiptc.c: if (fcntl(sockfd, F_SETFD, FD_CLOEXEC) == -1) {
./extensions/libxt_set.h: if (fcntl(sockfd, F_SETFD, FD_CLOEXEC) == -1)
It can use O_CLOEXEC flag with open() system call & SOCK_CLOEX...

[PATCH 1/2] Use gnulib set_nonblocking_flag function instead of fcntl.
The previous code:
fcntl (fd, F_SETFL, O_NONBLOCK)
was technically incorrect, because it would have reset any
other flags on the file descriptor.
Thanks: Eric Blake
