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
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.

Usually this function is called for appending some small files only
(like fs marks) but let's just make it more generic and capable of
handling bigger files easily. Increasing buffer to 1 KiB shouldn't hurt.

It was there in case of adding some "create" command options that should
be parsed before actually creating the output image. It seems we don't
need any at this point so let's drop this function for now.

There is no need to allocate buffer as big as the whole image in order
to calculate CRC32. It's enough to use small buffer and just read file
content block by block.

This requires changing this helper to accept initial/current CRC32
value as argument but it allows dropping duplicated (complex?) code
calculating the CRC32.

The init script generated something like "DEVICE=/dev/sda" when it should
have been generating "DEVICE /dev/sda". mdadm errors on this. Patch by jow.
Also changed the default sendmail path to /usr/sbin/sendmail. No package
in LEDE provides /sbin/sendmail. msmtp provides /usr/sbin/sendmail so use
that.
Also add a patch to fix file paths for mdadm runtime files. mdadm currently
errors on them since /run is missing. Once /run is added to stock LEDE, this
patch can be removed.

getrandom blocks until the random pool is being initialized.
Unfortunately, this code is being called early during init to create the
overlay filesystem, on some devices leaving little chance for a
successful random pool init.
True randomness is not that important here, so fix this issue by
sticking to using /dev/urandom, like in older versions of this code.

Enable linking with libblkid instead of using private (included) version.
The libblkid is ~210KBytes in size, but with using the shared library
the binaries are ~25KBytes smaller. This also brings it in sync with

busybox currently installs passwd into /usr/bin which prevents its
'full' shadow-utils variant from being installed.
Move the passwd applet to /bin to avoid that collision.
shadow also provides /usr/bin/login which doesn't collide with busybox
as the busybox login applet is installed at /bin/login.

busybox currently installs traceroute and traceroute6 into /usr/bin
which prevents their 'full' iputils variants from being installed.
Move those applets to /bin so they can coexist with their iputils
siblings using the same PATH convention already applied for coreutils

Fix memory leak on nvram_open() and nvram_open_rdonly().
For nvram_open(), the 'fd' should be closed on error, and
mmap_area should be unmap when nvram magic can not be found.
For nvram_open_rdonly(), the 'file' variable should free before
return. Once nvram_find_mtd() return successfully, it will allocate
memory to save mtd device string.
