Hi Erik,
Hi to all,
This is part five of the my_get*id story.
I've tweaked a bit this two functions to make them more flexible,
but this changes will not affect existing code.
Now they work so:
1) my_getpwuid( char *user, uid_t uid, int bufsize)

   if bufsize is > 0 char *user cannot be set to NULL
                     on success username is written on static allocated buffer
                     on failure uid as string is written to buffer and NULL is returned
   if bufsize is = 0 char *user can be set to NULL
                     on success username is returned
                     on failure NULL is returned
   if bufsize is < 0 char *user can be set to NULL
                     on success username is returned
                     on failure an error message is printed and the program exits

  2) 1) my_getgrgid( char *group, uid_t uid, int bufsize)

   if bufsize is > 0 char *group cannot be set to NULL
                     on success groupname is written on static allocated buffer
                     on failure gid as string is written to buffer and NULL is returned
   if bufsize is = 0 char *group can be set to NULL
                     on success groupname is returned
                     on failure NULL is returned
   if bufsize is < 0 char *group can be set to nULL
                     on success groupname is returned
                     on failure an error message is printed and the program exits

This changes were needed mainly for my new id applet.
It is somewhat bigger then the previous but matches the behaviour of GNU id
and is capable to handle usernames of whatever length.
BTW: at a first look it seems to me that it will integrate well (with just a few changes)
with the pending patch  in patches/id_groups_alias.patch.
The increase in size is balanced by the removal of my_getpwnamegid.c
from libbb as this was used only in previous id applet and by size optimizations
made possible in whoami.c and in passwd.c.
I know that we are in feature freeze but I think that i've tested it enough
(at least I hope so.......).

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,

Hi to all,
This patch is useful for:
1) remove an unused var from extern char *find_real_root_device_name(const char* name)
    changing it to extern char *find_real_root_device_name(void).
2) fixes include/libbb.h, coreutils/df.c, util-linux/mount.c and  util-linux/umount.c accordingly.
3) fixes a bug, really a false positive,  in find_real_root_device_name() that happens if
    in the /dev directory exists a link named root (/dev/root) that should be skipped but
    is not. This affects applets like df that display wrong results

This removes the ipv6 specific xconnect dns lookups.  I do

was done, but that will just have to be tested.

Manuel,

    I rewrite bb_getopt_ulflags() function for more universal usage.
    My version support now:
    - options with arguments (optional arg as GNU extension also)
    - complementaly and/or incomplementaly and/or incongruously and/or list
    options
    - long_opt (all applets may have long option, add supporting is trivial)
    This realisation full compatibile from your version.
    Code size grow 480 bytes, but only coreutils/* over compensate this size
    after using new function. Last patch reduced over 800 bytes and not full
    applied to all. "mkdir" and "mv" applets have long_opt now for demonstrate
    trivial addition support long_opt with usage new bb_getopt_ulflags().
    Complementaly and/or incomplementaly and/or incongruously and/or list options
    logic is not trivial, but new "cut" and "grep" applets using this logic
    for examples with full demostrating. New "grep" applet reduced over 300
    bytes.

cleanups elsewhere.

74bcd16425 This incorporates Posix math support into ash. The Posix math support
was written by Aaron Lehmann <aaronl@vitelus.com> for busybox.  This
patch makes a few trivial changes to Aaron's code so that it can be
used (in theory) by the other shells as well...

eb1c94078f Reorganise unarchiving functions, more code re-use, only does single pass(no more linked lists), basis for supporting a cpio (and cheaper untar) applet, but cpio applet isnt included in this.
It effects ar, dpkg-deb applets only

f429baca86 I reworked make_human_readable_str so it now has a sane interface,
and then fixed up df, du, and ls to use the new interface.  I also
fixed up some formatting issues in ls while I was in there.
