supported since it's not easy to put 3 bytes accross 64Kb windows
of memory. This should not be such a problem with linear framebuffers.
There is no major interface modification except that the color type
becomes u_long instead of byte. So one just need to recompile his
application.

- errno is already set to ENOMEM (as appropriate) when asprintf(),
strdup(), or acl_init() fails
o acl_to_text.c:
- the return value of the initial strdup() is not checked
- errno is already set to ENOMEM (as appropriate) when asprintf
and acl_init() fails
- let the the default: case use 'goto error_label' for consistency

Rather than have a separate (misnamed) FTP_ANONYMOUS_PASSWORD constant, use
FTP_ANONYMOUS_USER (i.e. "anonymous") to construct the anonymous ftp password
if getlogin() fails.
- The stack was getting smashed by __grow_type_table()
- reallocf() was being called with the wrong pointer
- The maximum argument number was being incorrectly computed

This is needed when linking statically as SVR4 (ie, ELF) behavior is to only
link in a module if it satisfies an undefined strong reference from somewhere.
(this surprises a lot of people) Things are different when using shared libs,
the entire library and its modules and their symbols are available at run-time
(when the weak reference is seen to still be unsatisfied and is satisfied on
the spot), this is not the case with static libs.
Thus one can have a static binary with unresolved week references, and at
run-time dereference a NULL pointer.

interface was based on a draft version of POSIX whereas the final
(1996) version of POSIX specified that the error is returned.
While I'm here, fix getlogin_r so that it works for more than just
the first time it's called.

quitting every time. The way to free a CIRCLEQ was to loop until
the current == current->head, but the way to free a TAILQ is to loop
until current->head == NULL.
In any case, the CORRECT way to do it is a loop of TAILQ_EMPTY() checks
and TAILQ_REMOVE()al of TAILQ_FIRST(). This bug wouldn't have happened
if the loop wasn't hard-coded...
There may be more bugs of this type from the conversion.
so I am backing it out for now. The problem is that some random program
calling crypt() could be passing a DES salt and the crypt(3) library
would encrypt it in md5 mode and there would be a password mismatch as a
result. I wrote a validater function for the DES code to verify that
a salt is valid for DES, but I realized there were too many strange things
to go wrong. passwd(1), pw(8) etc still generate md5 passwords by default
for /etc/master.passwd, so this is almost academic. It is a big deal for
things that have their own crypt(3)-ed password strings (.htaccess,
etc etc). Those are the things I do not want to break.
My DES salt recognizer basically checked if the salt was either 2 or
13 characters long, or began with '_' (_PASSWORD_EFMT1). I think it
would have worked but I have seen way too much crypt() mishandling
in the past.
one-way hash functions for authentication purposes. There is no more
"set the libcrypt->libXXXcrypt" nightmare.
- Undo the libmd.so hack, use -D to hide the md5c.c internals.
- Remove the symlink hacks in release/Makefile
- the algorthm is set by set_crypt_format() as before. If this is
not called, it tries to heuristically figure out the hash format, and
if all else fails, it uses the optional auth.conf entry to chose the
overall default hash.
- Since source has non-hidden crypto in it there may be some issues with
having the source it in some countries, so preserve the "secure/*"
division. You can still build a des-free libcrypt library if you want
to badly enough. This should not be a problem in the US or exporting
from the US as freebsd.org had notified BXA some time ago. That makes
this stuff re-exportable by anyone.
- For consistancy, the default in absence of any other clues is md5. This
is to try and minimize POLA across buildworld where folk may suddenly
be activating des-crypt()-hash support. Since the des hash may not
always be present, it seemed sensible to make the stronger md5 algorithm
the default.
All things being equal, no functionality is lost.
