On machines with a coarse monotonic clock (here: TP-Link RE200 powered
by a MediaTek MT7620A) it can happen that the two DNS requests (for A
and AAAA) share the same transaction ID. If this happens the second
reply is wrongly dropped and nslookup reports "No answer".
Fix this by ensuring that the transaction IDs are unique.

Kernel setting `/proc/sys/kernel/pid_max` can be set up to 4194304 (7
digits) which will cause buffer overflow in busbox lock patch, this
often happens when running in a rootfs container environment.
This commit enlarges `pidstr` to 12 bytes to ensure a sufficient buffer
for pid number and an additional char '\n'.

The nslookup_lede/openwrt applet was introduced in de5b8e5. It was
introduced because:
Add a new LEDE nslookup applet which is compatible with musl libc
and providing more features like ability to specify query type.
In contrast to busybox' builtin nslookup applet, this variant does
not rely on libc resolver internals but uses explicit send logic
and the libresolv primitives to parse received DNS responses.
In busybox this applet is added in 0dd3be8. In particular, this commit
introduces the variable NSLOOKUP_BIG. We set the default to true and
so nothing changes.

PREFER_IPV4_ADDRESS is broken on IPv6-only hosts, as it causes busybox
utilities (ping, traceroute, ntpd) to forcibly use the A record instead of
the AAAA record when resolving a DNS name. This obviously fails when
there is no IPv4 connectivity. Since IPv6-only hosts or routers will only
become more common over time, disable PREFER_IPV4_ADDRESS to support this
use-case.
As a side-effect, disabling PREFER_IPV4_ADDRESS changes the default
resolution behaviour of busybox utilities on dual-stack hosts. Busybox
utilities now simply use the order given by getaddrinfo(), so they will
now prefer IPv6 addresses when resolving a name with both A and AAAA
records if there is IPv6 connectivity. This is in line with RFC 6724.
PREFER_IPV4_ADDRESS was likely intended to work around naive
implementations of getaddrinfo() that could return AAAA records first,
even on an IPv4-only host. But both musl (since 1.1.3) and glibc
correctly implement RFC 6724 for getaddrinfo() and check connectivity to
determine the correct order in which to return records. On IPv4-only
hosts, getaddrinfo() will return A records first, so there is no need for
the PREFER_IPV4_ADDRESS hack.

Before this commit, it was assumed that mkhash is in the PATH. While
this was fine for the normal build workflow, this led to some issues if
make TOPDIR="$(pwd)" -C "$pkgdir" compile
was called manually. In most of the cases, I just saw warnings like this:
make: Entering directory '/home/.../package/gluon-status-page'
bash: line 1: mkhash: command not found
bash: line 1: mkhash: command not found
bash: line 1: mkhash: command not found

While these were only warnings and the package still compiled sucessfully,
I also observed that some package even fail to build because of this.

variable points to $(STAGING_DIR_HOST)/bin/mkhash, which is always the

The rootfs squashfs is already highly (XZ) compressed. Storing the applet
messages in compressed form will increase the entropy and reduce the overall
image compression ratio.
Size diffs (compressed vs uncompressed):
busybox (the executable): 364596 vs 384804 bytes.
OpenWrt target images (the kernel image is unchanged, obviously):
omnia-medkit-openwrt-mvebu-cortexa9-cznic_turris-omnia-initramfs.tar.gz:
9163597 vs 9162531 bytes (1066 bytes difference).
openwrt-mvebu-cortexa9-cznic_turris-omnia-initramfs-kernel.bin:

Commit ad7c6102f2 ("busybox: fix missing install with suid bit set if

thus would install busybox setuid root by default which would result in
possibly unwanted change of current behaviour, so let's disable this
option by default in order to preserve the current status-quo.
For the record: disabling FEATURE_SUID to preserve the status-quo does
*not* imply the current status-quo is "safer", or for that matter, in
any way desireable. That is a discussion to be had on the mailing
lists.
Switching the FEATURE_SUID default to "n" is simply a compromise to

With FEATURE_SUID=y one can install busybox binary belonging to root
with the suid bit set, enabling some applets to perform root-level
operations even when run by ordinary users. Busybox then drops
privileges for applets that don't need root access, before entering
their main() function.
Currently we don't install busybox binary with suid bit set, rendering
this feature unusable.
Note that we can't just "chmod u+s /bin/busybox" at runtime as a
"cheaper" solution: it would waste approximately 200KiB of FLASH (the
whole /bin/busybox binary gets copied into the overlay).
