b993b68b6c build: introduce $(MKHASH)
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
    bash: line 1: mkhash: command not found
    bash: line 1: mkhash: command not found
    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.

After applying this commit, the variable $(MKHASH) is introduced. This
variable points to $(STAGING_DIR_HOST)/bin/mkhash, which is always the
correct path.

0275ee5dde busybox: update to 1.33
Remove stime backport.

Remove static libgcc patch as upstream fixed it with
BUSYBOX_DEFAULT_STATIC_LIBGCC which defauls to off.

Remove date -k patch as it no longer applies. It's also pointless as
busybox' hwclock utility can do the same thing.

Remove ntpd patch as that seems to have been applied upstream.

Add smalll patch fixing compilation with SELinux. Upstream commit
2496616b0a8d1c80cd1416b73a4847b59b9f969a renamed the variable without
renaming it in the SELinux path.

Refresh config and patches.

Config refresh:

Refresh commands, run after busybox is first built once:

  cd package/utils/busybox/config/
  ../convert_menuconfig.pl ../../../../build_dir/target-mips_24kc_musl/busybox-default/busybox-1.33.0
  cd ..
  ./convert_defaults.pl < ../../../build_dir/target-mips_24kc_musl/busybox-default/busybox-1.33.0/.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)
* editors/Config.in: Add USE_GLIBC dependency to
  BUSYBOX_CONFIG_FEATURE_VI_REGEX_SEARCH (commit f141090)
* 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, networking/Config.in and util-linux/Config.in (commit 1da014f)

ad7c6102f2 busybox: fix missing install with suid bit set if FEATURE_SUID=y
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).

If a user finds that logd is too barebone for their needs and wishes
to have more control over syslog, the user presently has an option
to enable CONFIG_BUSYBOX_CONFIG_FEATURE_SYSLOG and configure syslog
with settings in /etc/syslog.conf.

Presently /etc/syslog.conf silently disappears on sysupgrade. This

1211832977 busybox: handle crypt() errors in loginutils
The crypt(3) function is allowed to fail with either EINVAL or ENOSYS when
the given salt is either invalid or when the requested algorithm is not
implemented.

In such a case, libbb's pw_encrypt() function will silently convert the
crypt() NULL return value into an empty string which is then processed
without further errors by utilities such as chpasswd or passwd, causing
them to set an empty password when an unsupported cipher is requested.

Patch the relevant users of pw_encrypt() to abort in case an empty hash
is returned by pw_encrypt() in order to mitigate the problem.

e4259bed3f busybox: udhcpc: no MSG_DONTROUTE when sending packet
This reverts a change made in Sep 2017 [1] which introduced
MSG_DONTROUTE flag to prevent udhcpc from reaching out to servers on a
different subnet. That change violates RFC2131 by forcing fully
configured clients, who got their configurations through an offer
relayed by a DHCP relay, from renewing through a unicast request
directly to the DHCP server, resulting in the client resorting to
boradcasting lease extension requests instead of unicasting them,
further breaking RFC2131.

The problem with MSG_DONTROUTE appears when talking to a properly
configured DHCP server that rejects non-compliant requests. Such server
will reject lease extension attempts sent via broadcast rather than
unicast, as is the case with Finnish ISPs Telia and DNA as well as
Estonian ISP Starman. Once the lease expires without renewal, udhcpc
enters init mode, taking down the interfaces with it, and thus causing
interruption on every lease expiry. On some ISPs (such as the ones
mentioned above) that can be once every 10-20 minutes. The interruptions
appear in the logs as such:
----
udhcpc: sending renew to x.x.x.x
udhcpc: send: Network unreachable
udhcpc: sending renew to 0.0.0.0
udhcpc: sending renew to 0.0.0.0
...
udhcpc: lease lost, entering init state
Interface 'wan' has lost the connection
Interface 'wan' is now down
Network alias 'eth0' link is down
udhcpc: sending select for y.y.y.y
udhcpc: lease of y.y.y.y obtained, lease time 1200
Network alias 'eth0' link is up
Interface 'wan' is now up
----

During lease extension, a fully configured client should be able to
reach out to the server from which it recieved the lease for extension,
regardless in which network it is; that's up to the gateway to find. [2]
This patch ensures that.

02fba1a181 busybox: drop providing virtual package ip
Drop providing the virtual package ip by busybox which was added in commit
1cec4d4ef0.

Letting busybox provide the virtual package ip is not optimal for the
following reasons :

	- Applications depending on ip expect either the ip-full or
	  ip-tiny package to be enabled.
	- Busybox ip applet cannot be added or removed at runtime

df0bd42fde build: add hardened builds with PIE (ASLR) support
Introduce a configuration option to build a "hardened" OpenWrt with
ASLR PIE support.

Add new option PKG_ASLR_PIE to enable Address Space Layout Randomization (ASLR)
by building Position Independent Executables (PIE). This new option protects
against "return-to-text" attacks.

Busybox need a special care, link is done with ld, not gcc, leading to
unknown flags. Set BUSYBOX_DEFAULT_PIE instead and disable PKG_ASLR_PIE.

If other failing packages were found, PKG_ASLR_PIE:=0 should be added to
their Makefiles.

busybox: add missing TARGET_CPPFLAGS and TARGET_LDFLAGS
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: streamline Makefile
Use default Build/Install steps where possible. No binary change in default
configuration, so PKG_RELEASE is not incremented.
