a4d45d423f The fact "tar tvjf thing.tbz" didn't work was due to the "-1" in -r11859,
which was apparently never tested.  That meant that there always had
to be at least one unparsed argument left over, which is not the case for
tar.

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 found that gcc in cvs (HEAD in 2005/02/11) reject the gzip source
in the busybox.

This is caused by changing gcc's error handling behavior(
The gcc check the function prototype more strictly).

I show the compilation log as follow:
-- compilation log

Hi!

I've created a patch to busybox' build system to allow building it in
separate tree in a manner similar to kbuild from kernel version 2.6.

That is, one runs command like
'make O=/build/some/where/for/specific/target/and/options'
and everything is built in this exact directory, provided that it exists.

I understand that applyingc such invasive changes during 'release
candidates' stage of development is at best unwise. So, i'm currently
asking for comments about this patch, starting from whether such thing
is needed at all to whether it coded properly.

'make check' should work now, and one make creates Makefile in build
directory, so one can run 'make' in build directory after that.

One possible caveat is that if we build in some directory other than
source one, the source directory should be 'distclean'ed first.

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.

fea4b446df Important bugfixes from Ian Campbell.
init_archive_deb_data()
        We want to filter for data.tar.* in the AR file not the TAR
        file, else we get nothing.

all_control_list()
        Make the 'extensions' array of control file names a global so it
        can be used in unpack_package as well. Name the global
        all_control_files. Don't hard code the length of
        all_control_files but instead used sizeof.

unpack_package()
        Only unpack the control files we are interested in (from
        all_control_files). Extract the data.tar.gz into / rather than
        the current directory.

dpkg_main()
        Configure packages in a second pass so all the packages being
        installed are unpacked before configuring.

Some purely cosmetic changes:

header
        update list of differences since two of them are no longer true.
        The .control file is no longer stored as a result of this patch
        -- it was redundant since the info is in status. New packages
        appear to be added to the end of the status file now rather than
        the start.

remove_package()
        Make message printing optional, so we can avoid a redundant
        message when replacing/upgrading a package. When we do print
        stuff then include the version number.

purge_package()
        Print "Purging xxx (yyy) ..." message like the other actions.

configure_package()
        Add "..." to "Setting up" message to be consistent with other
        actions.
