Hello everyone,

Busybox's insmod fails to locate a module when that module is the only one
existing in the /lib/modules directory (with a unique name).

Example:

# find /lib/modules/ -type f
/lib/modules/kernel/drivers/char/bios.o
# insmod bios
insmod: bios.o: no module by that name found
# touch /lib/modules/dummy
# find /lib/modules/ -type f
/lib/modules/kernel/drivers/char/bios.o
/lib/modules/dummy
# insmod bios
Using /lib/modules/kernel/drivers/char/bios.o

As long as there is another file in the /lib/modules directory, insmod
finds it OK.

I tracked the problem down to 'check_module_name_match()' in insmod.c:

It returns TRUE when a match is found, and FALSE otherwise. In the case
where there is only one module in the /lib/modules directory (or more that
one module, but all with the same name), 'recursive_action()' will return
TRUE and we end up on line 4196 in 'insmod.c' which returns an error.
[The reason it works with more than one module with different
names is that in this case there will always be one not matching,
'recursive_action()' will return FALSE and we end up in line 4189.]

Now, from the implementation of 'recursive_action()' and from other
usages of it (tar.c, etc.), it seems to me that FALSE should be returned
to indicate that we want to stop the recursion, so TRUE and FALSE should
be inverted in 'check_module_name_match()'.

At the same time, 'recursive_action()' continues to recurse even after
the recursive call has returned FALSE; again in my understanding and
other usages of it, we can safely stop recursing at this point.


Here is my patch against 1.00-pre8:

I've noticed a bug in the "autowidth" feature more, and is probably in
others.  The call to the function get_terminal_width_height() passes
in a file descriptor but that file descriptor is never used, instead
the ioctl() is called with 0.  In more_main() the call to
get_terminal_width_height() passes 0 as the file descriptor instead of
fileno(cin).  This isn't a problem when you more a file (e.g. "more
/etc/passwd") but when you pipe a file to it (e.g. "cat /etc/passwd |
more") the size of the terminal cannot be determined because file
descriptor 0 is not a terminal.  The fix is simple, I've attached a
patch for more.c and get_terminal_width_height.c.

d2b860fecb Patch from Vernon Sauder.
The off_t type is not a consistent size; it depends on the kernel options
(something about large file support). Therefore, the format string for
printing an address is not always the same.

817565a0ff For the time being, revert the changes for detecting copying
a directory into itself.  It is harder to do this correctly
than it appears.  Not trying at all seems a better compromise
for the time being, untill we can implement this correctly.

As Manuel points out, this is a flawed fix, and doesnt fix the
following:

mkdir -p cpa cpb cpc
cp -a cpa cpa/cpb/cpc

Attached what appears to be a more sane fix.  Apply on top of previous.
Please confirm sanity.

I was adding -s/--symbolic-link support to busybox cp when I noticed a
bug with -r/-a.  Test case:

mkdir -p test/out
cd test
busybox cp -a * out/

Will never return until we run out of open files or similar.
Coreutils cp on the other hand will error with "cannot copy a directory,
`out', into itself, `out'".  Patch attached.

ef8cd3be17 Make the loop support stuff be much less evil, and make it cope
with 2.6.x asm/posix_types.h, which has done singularly evil thing
by yanking __kernel_dev_t and renaming it.  The loop interface was
really poorly designed in the first place.  The new 64 bit loop
interface looks to be somewhat less horrible, too bad it is only
present in 2.6.x kernels.

4575bbf7b8 The variable 'complementaly' used to be allocated with calloc, which zeroed it
out during the allocation process.  When vodz changed it to be allocated on the
stack, he forgot to explicitly zero it, leaving its value filled with whatever
used to be sitting on the stack.  It would garbage values, depending on the
garbage that happened to be sitting on the stack when the function was called.
The result was that applets using bb_getopt_ulflags() were showing
unpredictable behavior (such as segfaults), which naturally broke many things.

1cda715bbc Fix a bug where mount could check the wrong device. st_rdev is the correct
device ID iff the named file is a character or block special device.  Otherwise
it is meaningless junk, in which case st_dev should be used.  This was done
incorrectly, which could cause mount to display bogus mount info.

e6dc439b3a Rework wget, the xconnect interface, and its various clients
in order to fix the problems with round robin DNS reported
by Andrew Flegg:
    http://busybox.net/lists/busybox/2003-October/009579.html

This removes the ipv6 specific xconnect dns lookups.  I do
not see why that would need to be special cased for ipv6 as
was done, but that will just have to be tested.

So IPV6 people -- please test this change!
