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.

Unconditionally pass TARGET_CPPFLAGS (not passed at all before) and
TARGET_LDFLAGS (passed only in certain non-default configuration before the
Makefile streamlining). Without these flags, hardening options
(PKG_FORTIFY_SOURCE and PKG_RELRO) were not actually applied to busybox.
The addition of these flags increases the size of the stripped busybox
binary by about 6KB (~4KB with fortify headers, ~2KB with "-znow -zrelro")
with the default hardening options PKG_FORTIFY_SOURCE_1 and PKG_RELRO_FULL.

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

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.

ntpd from Busybox supports peer-less (standalone) mode when it's started
with option -l and without any peer provided with option -p. In this
mode ntpd uses local time as reference and acts as stratum 1 server.
This mode can be used in isolated networks, where Internet access and/or
other NTP server/s are not available, but the device has some other way
of getting correct time, like e.g. GPS (ugps supports setting local time
by default).
Support for this mode was incorrectly disabled/removed in:

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.
