67b23e6043 getopt_ulflags -> getopt32. 
It is impossible to formulate sane ABI based on

Basically it means that you cannot portably use
more that 32 option chars in one call anyway...

1bfca7bac7 Cleanup headers and replace the zero padding with an even smaller version. 
One of the pads turned out to be unnecessary: sizeof(struct TarHeader) is
TAR_BLOCK_SIZE, the padding's in the struct.  The others could be done inline
with bb_common_bufsiz1.

This is a cleanup I did to Denis' patch long ago, but got sidetracked by
what turned into svn 15660.

3ee6c24ea2 Add --exclude option (to make uClibc-0.9.28 headers install using busybox tar). 
I have no idea how to apply bb_getopt_complementally to a --longopt that
has no short option.  The documentation from vodz has a bad case of
babelfish poisoning, and I can't understand it.  It sort of seems to
suggest there is a way, but what it is I have no idea.  So I used \n as
the short option, which is fairly unlikely to be used for something else. :)

Hi,
I've spent the half night staring at the devilish  my_getpwuid and my_getgrgid functions
trying to find out a way to avoid actual and future potential buffer overflow problems
without breaking existing code.
Finally I've  found a not intrusive way to do this that surely doesn't break existing code
and fixes a couple of problems too.
The attached patch:
1) changes the behaviour of my_getpwuid and my_getgrgid to avoid potetntial buffer overflows
2) fixes all occurences of this function calls in tar.c , id.c , ls.c, whoami.c, logger.c, libbb.h.
3) The behaviour of tar, ls and  logger is unchanged.
4) The behavior of ps with somewhat longer usernames messing up output is fixed.
5) The only bigger change was the increasing of size of the buffers in id.c to avoid
     false negatives (unknown user: xxxxxx) with usernames longer than 8 chars.
     The value i used ( 32 chars ) was taken from the tar header ( see gname and uname).
     Maybe this buffers can be reduced a bit  ( to 16 or whatever ), this is up to you.
6) The increase of size of the binary is not so dramatic:
     size busybox
       text    data     bss     dec     hex filename
     239568    2300   36816  278684   4409c busybox
    size busybox_fixed
       text    data     bss     dec     hex filename
     239616    2300   36816  278732   440cc busybox
7) The behaviour of whoami changed:
    actually it  prints out an username cut down to the size of the buffer.
    This could be fixed by increasing the size of the buffer as in id.c or
    avoid the use of my_getpwuid and use getpwuid directly instead.
    Maybe this colud be also remain unchanged......

Please apply if you think it is ok to do so.
The diff applies on today's cvs tarball (2004-08-25).
Thanks in advance,
Ciao,
Tito

4f807a84c5 BusyBox has no business hard coding the number of major and minor bits for a 
dev_t.  This is especially important now that the user space concept of a dev_t
and the kernel concept of a dev_t are divergant.  The only bit of user space
allowed to know the number of major and minor bits is include/sys/sysmacros.h
(i.e. part of libc).  When used with a current C library and a 2.6.x kernel,
this fix should allow BusyBox to support wide device major/minor numbers.

Erik - please apply.

Authors - please check that I didn't corrupt any meaning.

Package importers - see if any of these changes should be

I glossed over lots of sloppy capitalizations, missing apostrophes,
mixed American/British spellings, and German-style compound words.

What is "pretect redefined for test" in cmdedit.c?
