ab6a96f3f5 Config-devel.in: rename symbol KERNEL_GIT_BRANCH -> KERNEL_GIT_REF
The Download/git rule will do a `git checkout <git-ref>`.
So, we can use any ref we want.

No need to limit just to branches.

fce35bce0f config: support new symbol intro'd in kernel 4.12
Symbol CONFIG_INITRAMFS_FORCE allows to ignore the value passed by the
bootloader.

By default, all symbols containing INITRAMFS are wiped from the final
config and then re-added conditionally.

Add support for this symbol, as the build will stop otherwise
questioning the user about this option:

* Restart config...
*
*
* General setup
*
Cross-compiler tool prefix (CROSS_COMPILE) []
Compile also drivers which will not load (COMPILE_TEST) [N/y/?] n

Select the other CONFIG_ALL_* options in the hierarchy when the master
option is selected. Currently CONFIG_ALL_KMODS is not selected when the
build bot selects CONFIG_ALL_NONSHARED for example.

Now the rtc kmods should get build when CONFIG_ALL_KMODS,
CONFIG_ALL_NONSHARED or CONFIG_ALL and CONFIG_RTC_SUPPORT are selected
like it is done by the build bots for targets with rtc support.

ab20c638b6 x86: Set default baud rate on Geode images to 115200
Prior to commit 1496b95a0 ("x86: clean up default grub baudrate

19200 for net5501, 38400 for alix2, and 115200 for Geos.

It doesn't seem that there's a very good reason for varying from our
default 115200 baud, so let's make the Geode target do that instead.

4cc1f1ac1c x86: revert default root size back to 256 MB
2 GB is overkill and was only added to allow unlimited ext4 resizing,
which is a pretty rare use case. 256 MB allows resizing up to 256 GB,
which should be good enough for almost all users.

A lot of this is mostly irrelevant anyway, since you can just use
squashfs + ext4 overlay.

dc6cc04016 config: ext4: increase x86 rootfs size to 2GB to support online resize2fs
The current default rootfs size of 256MB in conjunction with 4K blocks
produces an ext4 filesystem which lacks the appropriate amount of backup GDT
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.

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 the required rules for creating a 4GB sdcard image according to this layout:

p1: rootfs (squashfs)
p2: rootfs_data (ext4)
This should be generic to any mvebu boards that can boot from block storage.

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.

02e2548b84 x86: use PARTUUID instead explicitly specifying the device by default
This changes the x86 image generation to match x86_64, using the PARTUUID for
the rootfs instead of explicitly configuring the device.

It unbreaks KVM with VirtIO, which uses /dev/vda2 instead of /dev/sda2.

Tested in QEMU/KVM with VirtIO, VirtualBox and VMware.

b1953bdf27 kernel: enable open by fhandle syscalls
This is needed by many services to function properly and as
all modern distributions got it enabled, it starts to be a
de-facto standard, i.e. user-space starts to silently depend
on it.

This also pulls in EXPORTFS, however, the kernel binary size
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.

v2: use menuconfig option instead of just enabling the option

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.
PIE not currently included.

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.
