blkid: add curly braces to do-while statement
Some say people read do-while statements are easily as while statements and
get wrong impression. This happens because do-whiles are not common.
Adding braces should make it easier to read the code.

libblkid: ensure uninitialized variable is not used [clang]
Following condition can be true if minix file system is corrupt, and versio

is unlikely.

login: prevent OOB read on illegal /etc/hushlogins
If the file /etc/hushlogins exists and a line starts with '\0', the
login tools are prone to an off-by-one read.
I see no reliability issue with this, as it would clearly need a
hostile action from a system administrator. But for the sake of
correctness, I've sent this patch nonetheless.
The SEND_UEVENT=yes|no line is not properly parsed, because the offset
jumps one byte too far behind the equal sign. Therefore, every
configuration that contains the line "SEND_UEVENT=yes" still does not
send an uevent.
The fix is simple: adjust the offset to be "12" instead of "13".
* hwclock.c: replace interpret_date_string() with parse_date().
Eliminates shell injection vulnerability from popen() date(1).
Removes system dependency on date(1).
Reduction in hwclock execution time.
Significant cleanup of hwclock.c code.
* Bug fix for "hwclock --predict --date 'bad_date'" printing:
hwclock: No usable set-to time. Cannot set clock.
The message now matches date(1) for an invalid --date argument.
