Multiple security fixes
* CVE-2018-0497 Remote plaintext recovery on use of CBC based ciphersuites through a timing side-channel
* CVE-2018-0498 Plaintext recovery on use of CBC based ciphersuites through a cache based side-channel
Disable OFB block mode and XTS block cipher mode, added in 2.11.0.
Disable Chacha20 and Poly1305 cryptographic primitives, added in 2.12.0
Patch the so version back to the original one, the API changes are
looking no so invasive.

Some of the ubi-tools in the upstream mtd-utils have been
broken by a bad patch upstream. It causes major breakage
during sysupgrade when the kernel, rootfs, ... volumes
are deleted in the wrong order.
This patch therefore reverts the faulty upstream commit which
fixes the bug.

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.

mbedtls changed in version 2.7.0 the soversion of the libmbedcrypto.so
library, all applications using this shared library have to be
recompiled to be able to load the new library.
Some binaries got rebuild to for the 2.7.0 release and are now using

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

libext2fs breaks krb5 by always installing its own copies of libcom_err.so
and libss.so.
Move the libraries into separate libcomerr and libss packages respectively
and add a host build recipe to stage the required compile_et and mk_cmds
utilities for use by other packages.
This allows the krb5 package to be fixed to use the system wide libcomerr
and libss libraries.

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.

In the add_match function in libbb/lineedit.c in BusyBox through 1.27.2,
the tab autocomplete feature of the shell, used to get a list of filenames
in a directory, does not sanitize filenames and results in executing any
escape sequence in the terminal. This could potentially result in code
execution, arbitrary file writes, or other attacks.

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
