While the -nopad option prevents mksquashfs from padding the
image to an arbitrary 4k. It does not take into consideration
that squashfs is programmed to have this 4k padding when it's
being used on on a block device... which is its main "use-case".
Now, after a week long discussion on the ML that included a
back-and-forth between some of the possible options.
But this is likely the best KISS patch to deal with the issue
right away given the limited resources.
From squashfs code point of view, be warned. The 4k padding is
not enough when dealing with devices that have a PAGE_SIZE
bigger than 4k.
if it turns out to be affecting you, then please look-up either:
"FS#2460 - kernel panic reading squashfs from ubi volume" bug
Or the discussion on the OpenWrt-Devel ML in
"amp821xx: use newly added pad-squashfs for Meraki MR24" and
"Squashfs breakage lottery with UBI..."
before making an educated guess.
Note: This will not affect the "tiny"/small flash devices as
much as it seems at first. This is because the the rootfs_data
partition that follows uses jffs2. And it requires to be aligned
to the flash block-size in order to work at all.
So either the involved FSes will meet in the middle as before,
or not at all. But in that latter case the image was already
hoping for the "undefined behaviour" gamble to turn out in its
favour and this is probably why this was unnoticed for so long.

Underscores don't harm in filenames, however the sanitize function from
version.mk replaces them, causing inconsistent filenames.
A fix tried to solve this previously via
dfe99645db however I did not look close
enough:

openwrt-ath79-generic_8dev-carambola2.manifest # patched

Eventually the sanitization of PROFILES *could* be removed as more and

Some devices are produced and sold under different names. To debloat
the buildroot but keeping it complete, new variables are introduced to
handle different namings. Below an example taken from a recent PR[0]
DEVICE_VENDOR := Arcadyan
DEVICE_MODEL := ARV4520PW
DEVICE_ALT0_VENDOR := Vodafone
DEVICE_ALT0_MODEL := Easybox 800
DEVICE_ALT1_VENDOR := Airties
DEVICE_ALT1_MODEL := WAV-281
With this commit the buildroot is extended to take care of up to three
alternative namings. The primary title plus alternatives names (if
defined) are shown in the `make menuconfig` dialog. Selecting on of
devices automatically selects all alternative names as they share the
same profile.
A list of the newly introduced variables:
DEVICE_ALT0_VENDOR :=
DEVICE_ALT0_MODEL :=
DEVICE_ALT0_VARIANT :=
DEVICE_ALT1_VENDOR :=
DEVICE_ALT1_MODEL :=
DEVICE_ALT1_VARIANT :=
DEVICE_ALT2_VENDOR :=
DEVICE_ALT2_MODEL :=
DEVICE_ALT2_VARIANT :=

Allow overriding the default selection state for Devices, similar to
setting a default for packages.
E.g. by setting DEFAULT to n, they won't be selected by default anymore
when enabling all device in the multi device profile.
This allows preventing images being built by the default config for
known broken devices, devices without enough RAM/flash, or devices not
working with a certain kernel versions.
This does not prevent the devices from being manually selected or images
being built by the ImageBuilder. These devices often still have worth
with a reduced package-set, or as a device for regression testing, when
no better device is available.

The manifest file is based on IMG_PREFIX and PROFILE_SANITIZED, whereas
the latter takes a string like DEVICE_8dev_carambola2 and sanitizes it.
This behaviour results in a useless "device_" profile-prefix in the
device manifest filename. Now uses *subst* to remove that.
Therefore this patch results more consistent device file names:
openwrt-ath79-generic-8dev_carambola2-initramfs-kernel.bin
openwrt-ath79-generic-8dev-carambola2.manifest
openwrt-ath79-generic-8dev_carambola2-squashfs-sysupgrade.bin

This allows the definition of DEVICE_VENDOR, DEVICE_MODEL and
DEVICE_VARIANT. All three are merged together to look the same as the
current DEVICE_TITLE. Also, if DEVICE_TITLE is set it's directly used as
a *fallback* for devices which weren't upgraded yet.
This is based on the work of @sudhanshu16.
The motivation is to create JSON files based on provided metadata,
needing clear differentiation between vendor, model and revision.

BIN_DIR can be set to overwrite the output path for new images. This is an
advertised feature for the imagebuilder and is used by systems like
LibreMesh's chef.
The legacy images are build using a new sub-make which doesn't receive the
variable overwrites of the parent make process. As result, the BIN_DIR is
automatically defined to the default value from rules.mk. The images will
therefore not be placed in the output path which was selected by the user.
Providing BIN_DIR as an explicit variable override to the sub-make works
around this problem.

While helping with review and build testing of a few 4.19 pull requests,
I've noticed, that dtc compiler in OpenWrt uses different options then
upstream kernel, which is leading to a very noisy output[1]. It wouldn't
be that bad per se, but a lot of such warnings aren't easily fixable so
I think, that we should follow what upstream does and simply ignore^W
silence those noisy warnings.
So this patch tries to syncs dtc compiler flags with upstream kernel
till version 4.19.13, disabling those warnings as they were added in
upstream kernel:
v4.6-rc1-2-gbc55398 dtc: turn off dtc unit address warnings by default
The newly added dtc warning to check DT unit-address without reg
property and vice-versa generates lots of warnings. Turn off the check
unless building with W=1 or W=2.
v4.11-rc2-11-g8654cb8 dtc: update warning settings for new bus and node/property
dtc gained new warnings checking PCI and simple buses, unit address
formatting, and stricter node and property name checking. Disable the
new dtc warnings by default as there are 1000s. As before, warnings are
enabled with W=1 or W=2. The strict node and property name checks are a
bit subjective, so they are only enabled for W=2.
v4.16-rc3-9-g4fd98e3 scripts: turn off some new dtc warnings by default
The latest dtc update adds some new noisy warnings, so turn them off by
default. Disable 'avoid_unnecessary_addr_size' and 'alias_paths'. They
can be re-enabled by building with 'W=1'.
v4.17-rc1-27-g74656b6 kbuild: disable new dtc graph and unit-address warnings
dtc gained some new warnings for OF graphs and unique unit addresses,
but they are currently much too noisy. So turn off
'graph_child_address', 'graph_port', and 'unique_unit_address' warnings
by default. They can be enabled by building dtbs with W=1.

Add the ABI_VERSION source makefile variable to the binary package basename
and resolve source dependencies on packages with ABI_VERSION set to such
expanded names.
If for example a package specifies DEPENDS:=libopenssl while the OpenSSL
Makefile specifies ABI_VERSION:=1.0.0, the resulting ipk control data
dependency will be "Depends: libopenssl1.0.0" and the libopenssl ipk file
will be called "libopenssl1.0.0_<version>_<arch>.ipk".
The next time a library such as OpenSSL is updated to an incompatible
version, the ABI_VERSION shall be changed accordingly to prevent opkg from
simply upgrading to an incompatible library without considering the
dependencies of already installed packages.
Also introduce another "SourceName" control field which is required by
the newly introduced "scritps/ipkg-remove" to determine the proper related
.ipk files to delete upon buildroot package clean operations.

We currently could (ab)use IMAGES for this task, but the downside is,
that the filenames has filesystem tied to the filename, which might be
confusing as the artifact itself don't has to be used with that specific
filesystem. Another downside is, that the artifacts built with IMAGES
target are build for every FILESYSTEMS filesystem.
Consider following use case:
define Device/apalis
...
FILESYSTEMS := ext4 squashfs
IMAGES := spl-uboot.bin recovery.scr
IMAGE/spl-uboot.bin := append-uboot-spl | pad-to 68k | append-uboot
IMAGE/recovery.scr := recovery-scr
endef
Where we would get target binaries with following filenames:
openwrt-imx6-apalis-squashfs.recovery.scr
openwrt-imx6-apalis-squashfs.spl-uboot.bin
openwrt-imx6-apalis-ext4.recovery.scr
openwrt-imx6-apalis-ext4.spl-uboot.bin
With proposed patch, we could now just do:
define Device/apalis
...
ARTIFACTS := spl-uboot.bin recovery.scr
ARTIFACT/spl-uboot.bin := append-uboot-spl | pad-to 68k | append-uboot
ARTIFACT/recovery.scr := recovery-scr
endef
Which would produce target binaries with following filenames:
openwrt-imx6-apalis-recovery.scr
openwrt-imx6-apalis-spl-uboot.bin

The image production rules does not have the initramfs-image
as a dependency. So, from make’s perspective initramfs
creation can run independently/in parallel with the image
generation code in the target's Makefile.
This is a problem for devices that have to use the initramfs
for the image creation and can lead to broken images.

When generating per-device rootfs directories, the ./etc/opkg/ directory
is moved away prior to calling opkg install, opkg remove and rootfs_prepare.
After the opkg invocations and the rootfs_prepare macro call, the saved opkg
config directory is supposed to be moved back to its previous ./etc/opkg
location.
The mv command however can fail to properly restore the directory under
certain circumstances, e.g. when the prior opkg or files/ overlay copy
operations caused a new ./etc/opkg/ directory to be created.
In this case, the backed up directory (named target-dir-$hash.opkg) will be
moved into the preexisting ./etc/opkg/ directory instead, causing the opkg
configuration to be located in a wrong path on the final rootfs, e.g. in
/etc/opkg/target-dir-$hash.opkg/distfeeds.conf instead of
/etc/opkg/distfeeds.conf.
Solve this problem by replacing the naive "mv" command with a recursive
"cp -T" invocation which causes the backed up directory tree to get merged
with the destination directory in case it already exists.
Also perform the rootfs_prepare macro call after restoring the opkg
configuration, to allow users to override it again by using the files/
overlay mechanism.
