# 241848 22-Oct-2012 eadler

Check the return error of set[e][ug]id. While this can never fail in the
current version of FreeBSD, this isn't guarenteed by the API.
Custom security modules, or future implementations of the setuid and
setgid may fail.

# 239991 01-Sep-2012 ed

Rework all non-contributed files that use `struct timezone'.

This structure is not part of POSIX. According to POSIX, gettimeofday()
has the following prototype:

int gettimeofday(struct timeval *restrict tp, void *restrict tzp);

Also, POSIX states that gettimeofday() shall return 0 (as long as tzp is
not used). Remove dead error handling code. Also use NULL for a
nul-pointer instead of integer 0.

While there, change all pieces of code that only use tv_sec to use
time(3), as this provides less overhead.


# 231994 22-Feb-2012 kevlo

Handle NULL return from crypt(3). Mostly from DragonFly


# 227169 06-Nov-2011 ed

Add missing static keywords to lock(1)


# 216737 27-Dec-2010 ed

Fix style bug introduced in r216696.

Additional indentation caused the line to become longer than 80 columns.


# 216696 25-Dec-2010 ed

Slightly improve output of lock(1).

- Remove the /dev/ portion of the TTY name.
- In case we use lock -p, print the username that was used to obtain the
password hash.


# 216370 11-Dec-2010 joel

Remove the advertising clause from UCB copyrighted files in usr.bin. This
is in accordance with the information provided at
ftp://ftp.cs.berkeley.edu/pub/4bsd/README.Impt.License.Change

Also add $FreeBSD$ to a few files to keep svn happy.

Revert most part of 200420 as requested, as more review and polish is
needed.

Remove unneeded header includes from usr.bin/ except contributed code.

Tested with: make universe


# 124824 22-Jan-2004 cperciva

Two fixes here:
1. If fgets fails, don't go into an infinite cpu-intensive loop. Instead,
check to see if the terminal still exists, and sleep(1) otherwise.
2. When we check to see if the terminal still exists, make sure we're not
mislead by EINTR. This could have been a security issue, but fortunately
the current implementation of tcgetattr doesn't EINTR.

# 119632 01-Sep-2003 kan

Eliminate last three uses of varargs.h in the tree. These three files
were including varargs.h file but did not use any of its macros,
so they escaped the clean-up before.


# 110609 10-Feb-2003 tjr

Make this work without COMPAT_43 by using tcgetattr()/tcsetattr() instead
of ioctl TIOCGETP/TIOCSETP.


# 102944 04-Sep-2002 dwmalone

ANSIify function definitions.
Add some constness to avoid some warnings.
Remove use register keyword.
Deal with missing/unneeded extern/prototypes.
Some minor type changes/casts to avoid warnings.

# 100806 28-Jul-2002 dd

Add a -v option that prevents switching virtual terminals while this
terminal is locked. This permits the user to easily lock the entire
console from a single terminal.


# 99709 10-Jul-2002 dd

Correct a comment: Typing in the root password at the "Key:" prompt
doesn't (and shouldn't) work.


# 99708 10-Jul-2002 dd

Fix indentation: Don't use space where tabs will do; specifically,
don't use spaces at the beginning of a line where tabs are normally
used (the worst thing was that half of this file was right (tabs) and
half was wrong (spaces), making for painful reading).

Closes PR bin/1567

/usr/bin/lock can be used to lock a terminal much like xlock does
for your X-windows session. Problem is, /usr/bin/lock cannot lock
your terminal indefinately. Rather you must specify a timeout
value, after which, your terminal is unlocked and become unsecured.

I have added a ``-n'' no timeout option to /usr/bin/lock
Currently the only way to get this functionality is to use a huge
timeout value and hope it is long enought (in time). This method
also requires you to know the maxium number of minutes you are
allowed to specify.
