Hannu Nyman b6cbbbb6ef busybox: update to version 1.34.0 
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)

config BUSYBOX_CONFIG_UDHCPD
bool "udhcpd (21 kb)"
default BUSYBOX_DEFAULT_UDHCPD
help
udhcpd is a DHCP server geared primarily toward embedded systems,
while striving to be fully functional and RFC compliant.
config BUSYBOX_CONFIG_FEATURE_UDHCPD_BASE_IP_ON_MAC
bool "Select IP address based on client MAC"
default BUSYBOX_DEFAULT_FEATURE_UDHCPD_BASE_IP_ON_MAC
depends on BUSYBOX_CONFIG_UDHCPD
help
If selected, udhcpd will base its selection of IP address to offer
on the client's hardware address. Otherwise udhcpd uses the next
consecutive free address.
This reduces the frequency of IP address changes for clients
which let their lease expire, and makes consecutive DHCPOFFERS
for the same client to (almost always) contain the same
IP address.
config BUSYBOX_CONFIG_FEATURE_UDHCPD_WRITE_LEASES_EARLY
bool "Rewrite lease file at every new acknowledge"
default BUSYBOX_DEFAULT_FEATURE_UDHCPD_WRITE_LEASES_EARLY
depends on BUSYBOX_CONFIG_UDHCPD
help
If selected, udhcpd will write a new file with leases every
time a new lease has been accepted, thus eliminating the need
to send SIGUSR1 for the initial writing or updating. Any timed
rewriting remains undisturbed.
config BUSYBOX_CONFIG_DHCPD_LEASES_FILE
string "Absolute path to lease file"
default BUSYBOX_DEFAULT_DHCPD_LEASES_FILE
depends on BUSYBOX_CONFIG_UDHCPD
help
udhcpd stores addresses in a lease file. This is the absolute path
of the file. Normally it is safe to leave it untouched.
config BUSYBOX_CONFIG_DUMPLEASES
bool "dumpleases (5.1 kb)"
default BUSYBOX_DEFAULT_DUMPLEASES
help
dumpleases displays the leases written out by the udhcpd.
Lease times are stored in the file by time remaining in lease, or
by the absolute time that it expires in seconds from epoch.
config BUSYBOX_CONFIG_DHCPRELAY
bool "dhcprelay (5.2 kb)"
default BUSYBOX_DEFAULT_DHCPRELAY
help
dhcprelay listens for DHCP requests on one or more interfaces
and forwards these requests to a different interface or DHCP
server.
config BUSYBOX_CONFIG_UDHCPC
bool "udhcpc (24 kb)"
default BUSYBOX_DEFAULT_UDHCPC
help
udhcpc is a DHCP client geared primarily toward embedded systems,
while striving to be fully functional and RFC compliant.
The udhcp client negotiates a lease with the DHCP server and
runs a script when a lease is obtained or lost.
config BUSYBOX_CONFIG_FEATURE_UDHCPC_ARPING
bool "Verify that the offered address is free, using ARP ping"
default BUSYBOX_DEFAULT_FEATURE_UDHCPC_ARPING
depends on BUSYBOX_CONFIG_UDHCPC
help
If selected, udhcpc will send ARP probes and make sure
the offered address is really not in use by anyone. The client
will DHCPDECLINE the offer if the address is in use,
and restart the discover process.
config BUSYBOX_CONFIG_FEATURE_UDHCPC_SANITIZEOPT
bool "Do not pass malformed host and domain names"
default BUSYBOX_DEFAULT_FEATURE_UDHCPC_SANITIZEOPT
depends on BUSYBOX_CONFIG_UDHCPC
help
If selected, udhcpc will check some options (such as option 12 -
hostname) and if they don't look like valid hostnames
(for example, if they start with dash or contain spaces),
they will be replaced with string "bad" when exporting
to the environment.
config BUSYBOX_CONFIG_UDHCPC_DEFAULT_SCRIPT
string "Absolute path to config script"
default BUSYBOX_DEFAULT_UDHCPC_DEFAULT_SCRIPT
depends on BUSYBOX_CONFIG_UDHCPC || BUSYBOX_CONFIG_UDHCPC6
help
This script is called after udhcpc receives an answer. See
examples/udhcp for a working example. Normally it is safe
to leave this untouched.
# udhcpc6 config is inserted here:
config BUSYBOX_CONFIG_UDHCPC6
bool "udhcpc6 (21 kb)"
default BUSYBOX_DEFAULT_UDHCPC6
depends on BUSYBOX_CONFIG_FEATURE_IPV6
help
udhcpc6 is a DHCPv6 client
config BUSYBOX_CONFIG_FEATURE_UDHCPC6_RFC3646
bool "Support RFC 3646 (DNS server and search list)"
default BUSYBOX_DEFAULT_FEATURE_UDHCPC6_RFC3646
depends on BUSYBOX_CONFIG_UDHCPC6
help
List of DNS servers and domain search list can be requested with
"-O dns" and "-O search". If server gives these values,
they will be set in environment variables "dns" and "search".
config BUSYBOX_CONFIG_FEATURE_UDHCPC6_RFC4704
bool "Support RFC 4704 (Client FQDN)"
default BUSYBOX_DEFAULT_FEATURE_UDHCPC6_RFC4704
depends on BUSYBOX_CONFIG_UDHCPC6
help
You can request FQDN to be given by server using "-O fqdn".
config BUSYBOX_CONFIG_FEATURE_UDHCPC6_RFC4833
bool "Support RFC 4833 (Timezones)"
default BUSYBOX_DEFAULT_FEATURE_UDHCPC6_RFC4833
depends on BUSYBOX_CONFIG_UDHCPC6
help
You can request POSIX timezone with "-O tz" and timezone name
with "-O timezone".
config BUSYBOX_CONFIG_FEATURE_UDHCPC6_RFC5970
bool "Support RFC 5970 (Network Boot)"
default BUSYBOX_DEFAULT_FEATURE_UDHCPC6_RFC5970
depends on BUSYBOX_CONFIG_UDHCPC6
help
You can request bootfile-url with "-O bootfile_url" and
bootfile-params with "-O bootfile_params".
comment "Common options for DHCP applets"
depends on BUSYBOX_CONFIG_UDHCPD || BUSYBOX_CONFIG_UDHCPC || BUSYBOX_CONFIG_UDHCPC6 || BUSYBOX_CONFIG_DHCPRELAY
config BUSYBOX_CONFIG_UDHCPC_DEFAULT_INTERFACE
string "Default interface name"
default BUSYBOX_DEFAULT_UDHCPC_DEFAULT_INTERFACE
depends on BUSYBOX_CONFIG_UDHCPC || BUSYBOX_CONFIG_UDHCPC6
help
The interface that will be used if no other interface is
specified on the commandline.
config BUSYBOX_CONFIG_FEATURE_UDHCP_PORT
bool "Enable '-P port' option for udhcpd and udhcpc"
default BUSYBOX_DEFAULT_FEATURE_UDHCP_PORT
depends on BUSYBOX_CONFIG_UDHCPD || BUSYBOX_CONFIG_UDHCPC || BUSYBOX_CONFIG_UDHCPC6
help
At the cost of ~300 bytes, enables -P port option.
This feature is typically not needed.
config BUSYBOX_CONFIG_UDHCP_DEBUG
int "Maximum verbosity level (0..9)"
default BUSYBOX_DEFAULT_UDHCP_DEBUG
range 0 9
depends on BUSYBOX_CONFIG_UDHCPD || BUSYBOX_CONFIG_UDHCPC || BUSYBOX_CONFIG_UDHCPC6 || BUSYBOX_CONFIG_DHCPRELAY
help
Verbosity can be increased with multiple -v options.
This option controls how high it can be cranked up.
Bigger values result in bigger code. Levels above 1
are very verbose and useful for debugging only.
config BUSYBOX_CONFIG_UDHCPC_SLACK_FOR_BUGGY_SERVERS
int "DHCP options slack buffer size"
default BUSYBOX_DEFAULT_UDHCPC_SLACK_FOR_BUGGY_SERVERS
range 0 924
depends on BUSYBOX_CONFIG_UDHCPD || BUSYBOX_CONFIG_UDHCPC
help
Some buggy DHCP servers send DHCP offer packets with option
field larger than we expect (which might also be considered a
buffer overflow attempt). These packets are normally discarded.
If circumstances beyond your control force you to support such
servers, this may help. The upper limit (924) makes udhcpc accept
even 1500 byte packets (maximum-sized ethernet packets).
This option does not make udhcp[cd] emit non-standard
sized packets.
Known buggy DHCP servers:
3Com OfficeConnect Remote 812 ADSL Router:
seems to confuse maximum allowed UDP packet size with
maximum size of entire IP packet, and sends packets
which are 28 bytes too large.
Seednet (ISP) VDSL: sends packets 2 bytes too large.
config BUSYBOX_CONFIG_FEATURE_UDHCP_RFC3397
bool "Support RFC 3397 domain search options"
default BUSYBOX_DEFAULT_FEATURE_UDHCP_RFC3397
depends on BUSYBOX_CONFIG_UDHCPD || BUSYBOX_CONFIG_UDHCPC
help
If selected, both client and server will support passing of domain
search lists via option 119, specified in RFC 3397,
and SIP servers option 120, specified in RFC 3361.
config BUSYBOX_CONFIG_FEATURE_UDHCP_8021Q
bool "Support 802.1Q VLAN parameters options"
default BUSYBOX_DEFAULT_FEATURE_UDHCP_8021Q
depends on BUSYBOX_CONFIG_UDHCPD || BUSYBOX_CONFIG_UDHCPC
help
If selected, both client and server will support passing of VLAN
ID and priority via options 132 and 133 as per 802.1Q.
