eb24a57b7f busybox: store applet usage messages uncompressed
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:

  9161688 vs 9160600 bytes (1088 bytes difference).

openwrt-mvebu-cortexa9-cznic_turris-omnia-sysupgrade.img.gz:

 9729550 vs 9729230 bytes (320 bytes difference).

All in all, we save just a little bit over 1 kiB. As an added bonus, we
also don't have to decompress the messages twice, (first from squashfs,
then from the bzip2 message storage).

c5c652e5ad busybox: use CLOCK_MONOTONIC instead of gettimeofday
The clock_gettime(CLOCK_MONOTONIC) syscall exists for so long that the first
kernel version to support it is not even specified in the man page [1]. Let's
enable it on BusyBox by default. Otherwise, gettimeofday will be used instead,
which will give wrong results if the date/time is reset (time moving backwards).

f1410902e6 busybox: add glibc dependency for vi regex option
Build with musl libc fails with BUSYBOX_DEFAULT_FEATURE_VI_REGEX_SEARCH

8eab0a0036 busybox: disable default config option FEATURE_SUID=y
Commit ad7c6102f2 ("busybox: fix missing install with suid bit set if
FEATURE_SUID=y") actually fixes BUSYBOX_CONFIG_FEATURE_SUID option and
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
facilitate the merge of the changes that unbreak FEATURE_SUID.

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).

to enable CONFIG_BUSYBOX_CONFIG_FEATURE_SYSLOG and configure syslog

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.

d13e86d4c2 procd: Add wrapper for uci_validate_section()
This adds a wrapper (uci_load_validate) for uci_validate_section() that
allows callers (through a callback function) to access the values set by
uci_validate_section(), without having to manually declare a
(potentially long) list of local variables.

The callback function receives two arguments when called, the config
section name and the return value of uci_validate_section().

If no callback function is given, then the wrapper exits with the value
returned by uci_validate_section().

This also updates several init scripts to use the new wrapper function.

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

busybox: remove i386-specific build flags
busybox tries to be smart and passes a number of additional flags to the
compiler. Unfortunately, the i386-specific flags break ABI compatiblity
with libc.

Fixes busybox crashes observed on x86-generic with GCC 7.

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.
