agetty uses NETLINK_ROUTE to be notified about network interface
changes. Unfortunately, the code that monitor the netlink FD does not
increment number of the monitored file descriptors when call
select(2), so the netlink notifications are invisible for agetty.

From v4.4, linux kernel starts to support direct I/O and
AIO to backing file for loop driver, so allow losetup to
enable the feature by using LOOP_SET_DIRECT_IO ioctl cmd.

fstrim takes mountpoint as argument but the bash completion
was completing it to a device node.

The stat(3) and access(3) are in this case almost interchangeable, so choose
the lightweight function with additional advantage checking the file is
executable.

Now we bump only PACKAGE_VERSION_MAJOR and PACKAGE_VERSION_MINOR
numbers. The PACKAGE_VERSION_RELEASE is always zero.
These numbers are used for LIBxxx_VERSION strings and Version: field
in the .pc files.
Unfortunately, if we keep PACKAGE_VERSION_RELEASE= always zero then
our bugfix releases are invisible for pkg-config.
(Although I don't think it's good idea to depend in code on any
library bugfix release, code should be about APIs).

Now the function uses result buffer for internal stuff (readlink), so
it requires that the buffer is large enough. This is unexpected as
caller assumes that the buffer has to be large enough for devname only.

If you have really paranoid syslog (or systemd who listens on /dev/log)
then it replaces in the message PID with a real PID from socket header
credentials:
# echo $PPID
1550
# logger -p info --stderr --id=$PPID "This is message baby!"
<14>Oct 29 11:22:13 kzak[1550]: This is message baby!
# journald -n 1
Oct 29 11:22:13 ws kzak[22100]: This is message baby!
^^^^^
This patch forces kernel to accept another *valid* PID if logger(1)
executed with root permissions; improved version:
# logger -p info --stderr --id=$PPID "This is message baby!"
<14>Oct 29 11:26:00 kzak[1550]: This is message baby!
# journald -n 1
Oct 29 11:26:00 ws kzak[1550]: This is message baby!

The iovec based solutions allow to send multiple strings by one
syscall (for example additional \n messages separator). We can also
use it to send additional socket header metadata (e.g.
SCM_CREDENTIALS) later.

This makes silly practical jokes impossible, like for example symlinking

time_t may change to 64-bit on 32-bit Linux kernels at some point;
at that point, it may be desireable to test for issues with dates
past 2038.

This reverts commit bc9007c372.
We need a better way, it seems that the original report is mostly
about udev rules disadvantages than about libblkid bug. See RH
bugzilla (#1172510) for more details.
The libmount provides way how to deal with parsing errors in fstab --
on error callback function is executed and according to the return
libmount manipulate with the malformed line, possible are three
states:
1/ fatal error; all file ignored (callback rc < 0)
2/ recoverable error; malformed line ignored (callback rc > 0)
3/ ignore the error (callback rc == 0)
The 2/ is the default if no callback specified.
Unfortunately our utils uses 3/. The correct way is to use 2/.
