In the add_match function in libbb/lineedit.c in BusyBox through 1.27.2,
the tab autocomplete feature of the shell, used to get a list of filenames
in a directory, does not sanitize filenames and results in executing any
escape sequence in the terminal. This could potentially result in code
execution, arbitrary file writes, or other attacks.

busybox currently installs passwd into /usr/bin which prevents its
'full' shadow-utils variant from being installed.
Move the passwd applet to /bin to avoid that collision.
shadow also provides /usr/bin/login which doesn't collide with busybox
as the busybox login applet is installed at /bin/login.

busybox currently installs traceroute and traceroute6 into /usr/bin
which prevents their 'full' iputils variants from being installed.
Move those applets to /bin so they can coexist with their iputils
siblings using the same PATH convention already applied for coreutils
and other drop-in 'full' versions.
Refresh existing patch while at it.

When invoking "nslookup_lede" with a domain argument and without explicit
query type, issue both A and AAAA queries and display the resulting IP
addresses in a numbered list style, similar to how the old BusyBox nslookup
used to output the records.
This is required for compatibility with certain scripts.

The ":*" optstring syntax was only recently introduced with BusyBox v1.26,
older versions need a corresponding hint in the "opt_complementary" variable
to denote flag values that should be stored as llist entries.
Add the required opt_complementary entry to fix random SIGBUS, SIGILL or
SIGSEGV related crashes on BusyBox 1.25.x when attempting to use the "-q"
flag of the "nslookup_lede" applet.

Since the LEDE nslookup applet is already specific to LEDE, move the

This fixes builds with external toolchains that don't automatically

The "new style" busybox applet approach moves all config and build
definitions related to an applet to its .c file. This makes the
patches easier to maintain, as they only add new files to the busybox
build directory, without modifying BusyBox files.

The Linux kernel uses two distinct fields to denote the routing table ID in
use by network routes; the 8 bit `rtm_table` member of `struct rtmsg` and the
32 bit `RTA_TABLE` netlink attribute.
If a routing table ID is larger than 255, the `RT_TABLE` attribute must be used
and the `rtm_table` field has to be set to the special `RT_TABLE_UNSPEC` value.
This commit adds a patch which...
- switches the *_n2a() and *_a2n() functions of rt_names.c to use dynamically
sized, name-sorted arrays instead of fixed arrays limited to 1024 slots in
order to support IDs up to 65535
- adds proper handling of high table IDs to iprule.c and iproute.c when
adding, removing and dumping ip rules and network routes
After this change, the Busybox ip applet fully supports IP rules with high ID
numbers, using the same logic as the full iproute2.

lock -n is similiar to flock -n. If the lock was already taken,
fail with exit code = 1 and write error message to stderr.
example:
if ! lock -n /tmp/foo ; then
echo lock exits.
else
echo lock was free. But is locked now.

> lock was free. But is locked now.

Patch sets the source IP address of DHCP request messages during rebind to the IP address
assigned to the udhcpc client. Source address 0.0.0.0 can only be used by a client prior
to obtaining its IP address (see RFC2131 § 4.1). Source IP address behavior lines up now with
the ISC dhcp client implementation for DHCP request messages during rebind and DHCP release
messages.

Some boards have the WLAN EEPROM stored in flash in big-endian format,
whereas the driver requires the EEPROM in little-endian format. The
conv=swab option in dd is particularly useful in this case. This patch
backports this feature from busybox-1.22 based on the following commits:
commit b941316ae5313be523b64f0a9151ee4decb2b35b dd: support conv=swab
commit 8395bd3f52f8ed46fa3ffc316b2d113afa748bae dd: fix example in a

Minor fix to existing patch which did not correctly implement -n support for the export command in ash. The VEXPORT flag of a variable was set in the first call to setvareq() and then remained set in the subsequent call, because the variable already existed in the environment.
Although /lib/functions.sh by default does not export variables (NO_EXPORT=1), this issue was leading to dirty environments.
Without this fix:
(ash) export A=1; export -n B=2; /bin/ash -c "echo \$A, \$B"

With this fix:
(ash) export A=1; export -n B=2; /bin/ash -c "echo \$A, \$B"
