5367f3400c Security improvements for games (largely from or inspired by OpenBSD). 
Games which run setgid from dm, but don't need to, should drop their
privileges at startup.

Games which have a scorefile should open it at startup, then drop all
privileges leaving just the open writable file descriptor.  If the
game can invoke subprocesses, this should be made close-on-exec.

Games with scorefiles should make sure they do not get a file
descriptor < 3.  (Otherwise, they could get confused and corrupt the
scorefile when using stdin, stdout or stderr.)

Some old setuid revokes from the days of setuid games change into gid
revokes.

to stderr.

The existing error message ("I don't know what xxx means") is
unchanged, as it is stylisticly in keeping with the light-hearted
nature of the program, and is also more likely to be accurate than the
"no such acronym" error message proposed in 8201.

ef49c17e92 This patch fixes adventure(6) to use `extern' on declarations of 
objects in its header file, and to add corresponding definitions to
init.c accordingly.  (See the C standard - relying on linker commons
where there are multiple uninitialised declarations of an object in
the program traditionally works on Unix, but is not standard C.)

The patch also removes a bit-rotten code fragment under #ifdef

ECMA don't supply copies of obsolete standards, though they will
supply printed copies of any or all of their current standards at no
charge.)

d8b3f85961 In atc(6), the function getAChar() has BSD and SYSV variants to deal 
with variations in EINTR behaviour, but the optimisation of using the
BSD version where the SYSV version isn't needed is insignificant.
This patch therefore simplifies the code by making there be just one
version, a more paranoid (about EOF when errno is already EINTR)
version of the SYSV code.  Since the BSD/SYSV defines are mainly used
to control whether BSD timers are used, this helps where BSD timers
but SYSV EINTR handling are wanted.

6c243d931c This patch improves the handling of save files in battlestar(6), by 
allowing the user to choose the name of the save file and specify it
on the command line when restoring.  It also eliminates a buffer
overrun in determining the path to the save file, and any particular
arbitrary limit on the name length.  In the name of a tidier home
directory, the default name is changed from "Bstar" to ".Bstar".

d5f85ed9c9 The patch below improves the security of the game atc(6), by having it 
open the score file at the start and then drop all setgid privileges
while keeping a (close-on-exec) file descriptor open to it.  In order
to allow this the static data files have to be made world readable.
In addition a potential buffer overrun with corrupted score files is
avoided by more careful use of scanf (note that SCORE_SCANF_FMT is
defined alongside the definition of the relevant structure).

adf74b1e92 This patch cleans up the handling of the variable `saved' in 
adventure(6).  The handling of this variable is somewhat confusing,
since it is used for two different purposes (controlling the time
required before a saved game can be restored, and controlling various
aspects of dwarf behaviour); in fact, it is also declared twice in
hdr.h.  Except possibly when saving a game fails, these uses can never
interfere; when used for controlling dwarf behaviour, we always have
saved == -1.  This can be better understood with reference to the
original PDP-10 FORTRAN source (URL in patch, since hdr.h references
the comments of the FORTRAN as still relevant to this version) of
which the C version is a direct translation: the wrong value for
`saved' meant that someone was cheating and had bypassed normal
initialisation.  Saving was done by halting and telling the user to
save their core image, so the question of carrying on after saving
failed to open the output file did not arise.

This patch separates the uses of `saved' into uses of two separate
variables.

148eb780dc This patch makes fish(6) honour PAGER for viewing the instructions. 
The detailed behaviour follows POSIX.2.  A similar patch for wump(6)
which was accepted is in bin/6699.  Fish does not need any setgid
privileges it gets from dm, so this patch also moves the gid resetting
earlier.

92932dfcc8 The patch below makes the game backgammon(6) use `const' where 
appropriate.  It also removes some obsolete, unused code to check the
number of users on the system (obsoleted by dm); removes a prototype
for an unused function that was removed earlier; and removes a control
character from one message that was I think intended to clear the
screen on some particular terminal (though I can't find the comment to
that effect in any of the BSD source trees I have handy) but no longer
serves any useful purpose.

From PR 6580 by Joseph Myers <jsm28@cam.ac.uk>.

Also contains two more patches, one in teachgammon/tutor.h (by Joseph)
and one in common_source/fancy.c (by me).

24f809b060 The game sail(6) has a function Write() which is used both with 
integer arguments and with string arguments (cast to long, and in one
place to int).  The patch here cleans this up, making it into two
separate functions; this allows for the game to be made const-correct
in future and improves portability.

The patch also contains two other fragments: a change to use the
symbolic constant SEEK_END with fseek(), and a change to use snprintf
in one place to avoid a buffer overrun.

c7bcded63e The patch below does some minor cleanup of adventure(6): an additional 
use of const I missed in bin/6041; avoiding a signed/unsigned warning;
marking an unused parameter as such; revoking setgid privileges
(including the saved gid) rather than setuid ones; includes and
function prototypes in setup.c; the string passed to err() should not
end with a `.'.  Together with the patch sent concerning adventure's
EOF handling, this synchronises adventure(6) in NetBSD with the Linux
port of the NetBSD games.
