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
Hi,
With the following /etc/fstab (any two or more lines of nfs), mount -a
-t nfs causes a segmentation faults.
server:/exports/aaa /mnt/aaa nfs defaults 0 0
server:/exprots/bbb /mnt/bbb nfs defaults 0 0
In util-linux/nfsmount.c, it overwrites malloc'ed pointer *mount_opts
with a static pointer. With this patch it does proper memory realloc
and data copy instead.
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.

With job control enabled, ash fails to tcsetpgrp back to initialpgrp
upon exit. exitshell() should call setjobctl(0) to do this.
Context: I am using a lightweight menu system (replimenu[.sf.net]) on my
console, which invokes "/bin/sh -i -c /bin/login", where /bin/sh and
/bin/login are busybox applets. /bin/sh is ash, with
CONFIG_ASH_JOB_CONTROL=y as the sole suboption. The shell of the user
concerned (nobody) is also /bin/sh (ash). When the user /bin/sh exits
(and thereby login and its parent sh), replimenu receives EIO when it
tries to read from the terminal.
"As noticed today by Steven Scholz, the od's `-v' was broken.
I've fixed that and now both the flags `-v' and `-a' are OK"
Fixes a segfault in
echo "uuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuu\02bar\4"| ./busybox od -av
Support for /etc/modprobe.conf (for 2.6 kernels) should likely be added
to bb's modprobe, see attached patch.
modprobe.conf is just a (even simpler) variant of modules.conf
"I have a need to _really_ know if the interface was properly configured
via ifup so I made busybox's ifupdown pass the return codes through rather
than dropping them on the floor."
"All the functions in ifupdown.c return 1 on success and 0 on failure
(which happens to the opposite of standard practices but whatever).
So it is important for all these functions to not blindly return 1."
"The problem with blindly returning ret, even if it is != 1, is the
callers expect a 0 or 1 and accumulate the return codes. So a function that
makes 3 calls to execute will have a value of 3 accumulated. That value
of 1 (success) was almost always returned even if 1 of the commands in the
command sequence failed. The attached patch fixes the lack of checking
to verify thar result == expected_reult."
