9c8e0b0e8a build: enable gzipped images for armvirt and malta
As we're now going to pad all images by default to 128MiB let's enable
compression of the images for armvirt and malta in order to save some
space and bandwidth.

469ba337a7 build: make TARGET_ROOTFS_PARTSIZE 128MiB by default
As we're now going to pad all images by default, lets decrease the
default rootfs partition size from 256MiB to 128MiB in order to save
some space.

I'm keeping it above 100MiB in order to keep current behavior, where
overlay filesystem is using F2FS.

d03ef97c1b build: remove TARGET_IMAGES_PAD option
It's being used only in x86 target to produce combined images, where
it's mandatory to have padded images in order to produce working
squashfs combined images usable in QEMU.

Currently we're producing unusable x86 combined squashfs images
(18.06.1, 18.06.2 and snapshots) as we don't enable TARGET_IMAGES_PAD,
thus providing very small space for the overlay filesystem, leading to
the following with OpenWrt 18.06.1 r7258-5eb055306f images on x86 QEMU:

 root@(none):/# mount | egrep 'root|overlay'
  /dev/root on /rom type squashfs
  /dev/loop0 on /overlay type ext4
  overlayfs:/overlay on / type overlay

 root@(none):/# df -h | egrep 'root|overlay|Size'
  Filesystem                Size      Used Available Use% Mounted on
  /dev/root                 2.5M      2.5M         0 100% /rom
  /dev/loop0              113.0K      8.0K     97.0K   8% /overlay
  overlayfs:/overlay      113.0K      8.0K     97.0K   8% /

So we should rather ensure proper image padding in image generation code
and we shouldn't rely on config options in order to generate usable
images.

5cd49395d3 lantiq/xrx200: enable initramfs images
Commit eae6cac6a3 ("lantiq: add support for AVM FRITZ!Box 7362 SL"), but
one needs an initramfs image to flash OpenWrt from stock firmware (as
described in the commit log). This patch has the initramfs image built
by default.

Thanks to blogic (for pointing to the FEATURES declaration in the target
Makefiles) and Musashino on the forum for suggesting
config/Config-images.in needed editing too. While at it, reorder the
TARGET_INITRAMFS_COMPRESSION_LZMA declarations alphabetically.

This patch will result in initramfs images for all lantiq subtargets
that have the ramdisk flag set. I tested on the falcon and ase
subtargets, which lack that flag, to confirm they don't produce any
initramfs images with this patch - which they do not.

Given the limited scope of the lantiq (sub)target(s), blogic indicated
this should be OK.

da50f027f0 config: kernel: Fix missing symbol on brcm2708 with CGROUPS
When CGROUP block io is enabled a new symbol is exposed and needs to
be set or unset else kernel oldconfig hangs waiting for input during
normal OpenWrt builds.  Therefore add sane defaults for this symbol
in that case.  Also, the defaults brcm2708 are different than generic
defaults because the platform's defconfig enables BLK_DEV_THROTTLING

upstream's kernel, not in OpenWrt config-4.xx).

cf7154db07 kernel: only optimized for size if small_flash
Add a new config option to allow to select the default compile
optimization level for the kernel.

Select the optimization for size by default if the small_flash feature is
set. Otherwise "Optimize for performance" is set.

Add the small_flash feature flag to all (sub)targets which had the
optimization for size in their default kernel config.

Remove CC_OPTIMIZE_FOR_* symbols from all kernel configs to apply the new
setting.

Exceptions to the above are:

  - lantiq, where the optimization for size is only required for the
    xway_legacy subtarget but was set for the whole target
  - mediatek, ramips/mt7620 & ramips/mt76x8 where boards should have
    plenty of space and an optimization for size doesn't make much sense
  - rb532, which has 128MByte flash

241e6dd3e9 build: cleanup SSP_SUPPORT configure option
Configure variable SSP_SUPPORT is ambiguous for packages (tor, openssh,
avahi, freeswitch). It means 'toolchain supporting SSP', but for toolchain
and depends it means 'build gcc with libssp'.

Musl no longer uses libssp (1877bc9d8f), it has internal support, so
SSP_SUPPORT was disabled leading some package to not use SSP.

No information why Glibc and uClibc use libssp, but they may also provide
their own SSP support. uClibc used it own with commit 933b588e25 but it was
reverted in f3cacb9e84 without details.

Create an new configure GCC_LIBSSP and automatically enable SSP_SUPPORT
if either USE_MUSL or GCC_LIBSSP.

entries to support online-resizing.

For x86 targets, increase the default rootfs size to 2048MB which allows
online resizing the filesystem to up to 2TB which is the current theoretical
maximum for LEDE, due to missing GPT support on the root block device.

Note that the filesystem artefact will not occupy 2GB on the build system as
the make_ext4fs utility uses sparse files to generate the filesystem images,
so the actual disk usage is much lower. Furthermore the filesystem images
are gzip compressed, shrinking them to only a few megabytes on the download
server.

d1ae4c4958 config: ext4: drop option to set maximum number of inodes
There is very little practical use to limit the number of available inodes on
an ext4 filesystem and the make_ext4fs utility is able to calculate useful
defaults by itself.

Drop the option to make resulting ext4 filesystems more flexible by default.

config: enable shadow passwords unconditionally
Configurations without shadow passwords have been broken since the removal
of telnet: as the default entry in /etc/passwd is not empty (but rather
unset), there will be no way to log onto such a system by default. As
disabling shadow passwords is not useful anyways, remove this configuration
option.

The config symbol is kept (for a while), as packages from feeds depend on
it.

Added gen_mvebu_sdcard_img.sh to facilitate creating an fixed-size sdcard image,
adding the bootloader and populating it with actual data.

Added the required rules for creating a 4GB sdcard image according to this layout:
p0: boot (fat32)
p1: rootfs (squashfs)
p2: rootfs_data (ext4)
This should be generic to any mvebu boards that can boot from block storage.

Added the new sdcard image to the Clearfog image profile.

08257a4053 apm821xx: use lzma compression for the initramfs images
The MR24's u-boot takes it sweet time decompressing the
LZMA-packed initramfs image. A user reported that
compared to the old gzip method in v2: it "takes a ton
longer to decompress like 4\x the old boot time for
decompression".

This patch also fixes a issue with the WNDR4700's initramfs
image getting to big and causing the following u-boot crash
during the decompression:

"Uncompressing Multi-File Image ... Error: inflate() returned -5
out-of-mem or overwrite error - must RESET board to recover"

This patch fixes both issues by reverting the MR24's initramfs
compression method back to gzip. And choosing to compress the
initramfs within the initramfs image as LZMA by default.

33beafa8d8 Configure IPv6 kernel options in config/Config-kernel.in
Revision 46834 changed IPv6 support from a module to builtin. But
since the configuration of the IPv6 kernel options was left in
package/kernel/linux/modules/netsupport.mk, this means that an
empty kmod-ipv6 module was still being generated (not packaged).

This patch moves the configuration of the IPv6 kernel options to
config/Config-kernel.in to remove this last bit of the module.

Note that CONFIG_IPV6_PRIVACY was dropped (enabled by default
since Linux v3.13), so this option is no longer needed.

increases only a little.
On ARM systems comes down to 800 bytes uncompressed and about
200 bytes compressed size.
On MIPS systems it's about 1.2 kB size increase of the LZMA
compressed kernel.

491f3fc048 Support for building an hardened OpenWRT
Introduce configuration options to build an "hardened" OpenWRT.

Options to enable Stack-Smashing Protection, FORTIFY_SOURCE and RELRO
have been introduced.

uClibc makefile now automatically detects if SSP support is necessary.

hostapd makefile has been fixed to use "^" as sed separator since
using a comma was problematic when using "-Wl,-z,now" and the like in
TARGET_CFLAGS.

Currently enabling SSP on user space depends on enabling SSP kernel
side, this is due to the fact that TARGET_CFLAGS are used to build
kernel modules (at least). Suggestions on how to avoid this are welcome.
Using "select" instead of "depends on" doesn't seem to work with choice
entries.

Tested with a lantiq (WBMR) router, GCC 4.8, uClibc and a subset of
the available packages.
Needs to be tested with GCC 4.9 and the remaining packages.

45e3540a3f config: Remove KERNEL_GIT_LOCAL_REPOSITORY option
The GIT_LOCAL_REPOSITORY option adds the --reference argument to the
git clone kernel command line, if KERNEL_GIT_CLONE_URI is set.

This option is intended to speed-up the repo creation by using local
objets rather than downloading it. However, a local repo can be cloned
much faster by setting GIT_LOCAL_REPOSITORY directly to the local tree.

In that case, git clone will bypass the normal "git aware" transport
mechanism and clone the repository by copying and hardlinking objects
rather than downloading it, resulting in a significant speed increase.

That makes the GIT_LOCAL_REPOSITORY option pretty useless so we'll just
remove it and recommand the usage of KERNEL_GIT_CLONE_URI directly.

76133009c9 sparse: add as a new package selectable from the config
This change does multiple things, all related to enable sparse usage as
a static analysis tool selectable from the OpenWrt configuration:
*add a KERNEL_SPARSE option in the config to add sparse to the kernel
 build (through the C=1 option usage)
*add sparse as a new host tools. It will get selected automatically when
 the above option will be enabled
