busybox: update to version 1.34.0

Browse Source 
Update busybox to version 1.34.0

* Remove upstreamed patches (205, 530, 540)

* Remove one old patch that does not apply any more. (203)
  That was originally introduced in 2008 with 563d23459,
  but does not apply after busybox restructuring with
  https://git.busybox.net/busybox/commit/networking/udhcp/dhcpc.c?h=1_34_stable&id=e6007c4911c3ea26925f9473b9f156a692585f30
  and
  https://git.busybox.net/busybox/commit/networking/udhcp/dhcpc.c?h=1_34_stable&id=1c7253726fcbab09917f143f0b703efbd2df55c3

* Refresh config and patches.

* Backport upstream fixes for
   - MIPS compilation breakage and
   - process substitution regression

Config refresh:

Refresh commands, run after busybox is first built once:

cd utils/busybox/
cd config/
../convert_menuconfig.pl ../../../../build_dir/target-aarch64_cortex-a53_musl/busybox-default/busybox-1.34.0
cd ..
./convert_defaults.pl < ../../../build_dir/target-aarch64_cortex-a53_musl/busybox-default/busybox-1.34.0/.config > Config-defaults.in

Manual edits needed afterward:

* Config-defaults.in:  OpenWrt config symbol IPV6 logic applied to
  BUSYBOX_DEFAULT_FEATURE_IPV6
* Config-defaults.in:  OpenWrt configTARGET_bcm53xx logic applied to
  BUSYBOX_DEFAULT_TRUNCATE (commit 547f1ec)
* Config-defaults.in:  OpenWrt logic applied to
  BUSYBOX_DEFAULT_LOGIN_SESSION_AS_CHILD (commit dc92917)
  BUSYBOX_DEFAULT_UDHCPC_DEFAULT_INTERFACE (just "")
* config/editors/Config.in: Add USE_GLIBC dependency to
  BUSYBOX_CONFIG_FEATURE_VI_REGEX_SEARCH (commit f141090)
* config/shell/Config.in : change at "Options common to all shells"  the symbol
  SHELL_ASH  -->  BUSYBOX_CONFIG_SHELL_ASH
   (discussion in http://lists.openwrt.org/pipermail/openwrt-devel/2021-January/033140.html
     Apparently our script does not see the hidden option while
     prepending config options with "BUSYBOX_CONFIG_" which leads to a
     missed dependency when the options are later evaluated.)
* Edit Config.in files by adding quotes to sourced items in
  config/Config.in, config/networking/Config.in and config/util-linux/Config.in (commit 1da014f)

When enabled, the watchdog device is opened and then immediately
magic-closed, before being opened a second time. This may be necessary
for some watchdog devices, but can cause spurious warnings in the
kernel log if the nowayout feature is enabled. If this workaround
is really needed for you machine to work properly, consider whether
it should be fixed in the kernel driver instead. Even when disabled,
the behaviour is easily emulated with a "printf 'V' > /dev/watchdog"
immediately before starting the busybox watchdog daemon. Say n unless
you know that you absolutely need this.

Stacy Harper reports that this script:
test() { . /tmp/bb_test; }
echo "export TEST=foo" >/tmp/bb_test
test 2>/dev/null
echo "$TEST"
correctly prints 'foo' in BusyBox 1.33 but hangs in 1.34.
Bisection suggested the problem was caused by commit a1b0d3856 (ash: add
process substitution in bash-compatibility mode). Removing the call to
unwindredir() in cmdloop() introduced in that commit makes the script
work again.
Additionally, these examples of process substitution:
while true; do cat <(echo hi); done
f() { while true; do cat <(echo hi); done }
f
result in running out of file descriptors. This is a regression from
v5 of the process substitution patch caused by changes to evalcommand()
not being transferred to v6.

From 7eed119b84b0f7efb7ef351940dd895dc2379eb3 Mon Sep 17 00:00:00 2001
From: Russell Senior <russell@personaltelco.net>
Date: Mon, 15 Mar 2021 23:27:58 -0700
Subject: [PATCH v2] udhcpc: ignore zero-length DHCP options
Discovered that the DHCP server on a TrendNet router (unknown model)
provides a zero-length option 12 (Host Name) in the DHCP ACK message. This
has the effect of causing udhcpc to drop the rest of the options, including
option 51 (IP Address Lease Time), 3 (Router), and 6 (Domain Name Server),
most importantly leaving the OpenWrt device with no default gateway.
The TrendNet behavior violates RFC 2132, which in Section 3.14 declares that
option 12 has a miniumum length of 1 octet. It is perhaps not a cosmic coincidence
that I found this behavior on Pi Day.
This patch allows zero length options without bailing out, by simply skipping them.
v2 changelog:
* advance the optionptr by two bytes, not one;
* add a message to warn about the rfc violation;

Subject: [PATCH] use SOURCE_DATE_EPOCH for timestamp if available
The SOURCE_DATE_EPOCH is an effort of the Reproducible Builds
organization to make timestamps/build dates in compiled tools
deterministic over several repetitive builds.
Busybox shows by default the build date timestamp which changes whenever
compiled. To have a reasonable accurate build date while staying
reproducible, it's possible to use the *date of last source
modification* rather than the current time and date.
Further information on SOURCE_DATE_EPOCH are available online [1].
This patch modifies `confdata.c` so that the content of the
SOURCE_DATE_EPOCH env variable is used as timestamp.
To be independent of different timezones between builds, whenever
SOURCE_DATE_EPOCH is defined the GMT time is used.

Subject: [PATCH] nslookup: mention QUERY_TYPE SRV
SRV lookups are supported since "6b4960155 nslookup: implement support
for SRV records" and should therefore be mentioned as a possible
QUERY_TYPE in the help message.
