configs/qemu: Update defconfigs to Linux 4.19.16

Linux version are changed to 4.19.16 (LTS) for all qemu defconfigs,
except for riscv. riscv defconfigs are left unchanged because they have
a custom Linux repository causing more difficulties when upgrading to
4.19 for riscv32. And for the riscv64, it has been updated recently to
Linux 4.20 by another contributor.

Patch for arm-versatile-nommu is changed into a git format

Add cache attributes for xtensa-lx60-nommu config because the commit
https://github.com/torvalds/linux/commit/7bb516ca5424e12b42124fab2906b6da9c81ba9c

utils/scanpypi: protect against zip-slip vulnerability in zip/tar handling

For details, see https://github.com/snyk/zip-slip-vulnerability

Older python versions do not validate that the extracted files are inside
the target directory.  Detect and error out on evil paths before extracting
.zip / .tar file.

Given the scope of this (zip issue was fixed in python 2.7.4, released
2013-04-06, scanpypi is only used by a developer when adding a new python

package/runc: add upstream security fix for CVE-2019-5736

The vulnerability allows a malicious container to (with minimal user
interaction) overwrite the host runc binary and thus gain root-level
code execution on the host. The level of user interaction is being able
to run any command (it doesn't matter if the command is not
attacker-controlled) as root within a container in either of these
contexts:

  * Creating a new container using an attacker-controlled image.
  * Attaching (docker exec) into an existing container which the
    attacker had previous write access to.

For more details, see the advisory:

https://www.openwall.com/lists/oss-security/2019/02/11/2

The fix for this issue uses fexecve(3), which isn't available on uClibc, so
add a dependency on !uclibc to runc and propagate to the reverse
dependencies (containerd/docker-engine).

support/testing: build a glibc toolchain for docker / docker-compose tests

runc (which is a reverse dependency of docker-engine) is about to gain a

There are currently no prebuilt x86_64 / core2 / glibc toolchains available,
so instead use the internal toolchain backend to build one.

While we are at it, drop the infra.basetest.BASIC_TOOLCHAIN_CONFIG

CVE-2019-6109: Due to missing character encoding in the progress

rcp, the server chooses which files/directories are sent to the client.
However, the scp client only performs cursory validation of the object

package/openjdk-bin: new package

Paradoxically, building OpenJDK requires a pre-existing JDK.  This
pre-existing JDK is called the "boot JDK."

The boot JDK for building JDK major version N should be a JDK of major
version N-1, so for building JDK11, JDK10 would be needed. This
requirement is an issue when building on most distributions, as the
host JDK tends to be JDK8.

The AdoptOpenJDK project provides binaries that can act as the boot
JDK to build the target JDK, which is what this package provides.

Currently, only a x86_64 host is supported, for two reasons:

1) A 32bit x86 binary distribution is not available from AdoptOpenJDK

2) We didn't had access to a host machine using an architecture other
   than x86-64

The provided unpack200 has an invalid RPATH and relies on libzlib.
When host-libzlib runs the install step, the following error is
generated:

*** ERROR: package host-libzlib installs executables without proper RPATH:
***   $(HOST_DIR)/bin/unpack200

Because unpack200 is a deprecated tool, removing it after installation
is safe and fixes the issue.

package/brcm-patchram-plus: fix license file hash

Commit 684bcc45e52a8300a2115799e96017b180695a14
("package/brcm-patchram-plus: fix build on sparc") added a patch that
modifies the src/main.c file, without paying attention to the fact
that this file is used as the license file for the package, and
therefore the .hash had to be updated at the same time. This commit
updates the license file hash as needed. There are obviously no
licensing related changes in the SPARC build fixes.

package/mosquitto: security bump to version 1.5.6

Fixes the following security issues:

CVE-2018-12551: If Mosquitto is configured to use a password file for
authentication, any malformed data in the password file will be treated as
valid. This typically means that the malformed data becomes a username and
no password.  If this occurs, clients can circumvent authentication and get
access to the broker by using the malformed username.  In particular, a
blank line will be treated as a valid empty username.  Other security
measures are unaffected.  Users who have only used the mosquitto_passwd
utility to create and modify their password files are unaffected by this
vulnerability.  Affects version 1.0 to 1.5.5 inclusive.

CVE-2018-12550: If an ACL file is empty, or has only blank lines or
comments, then mosquitto treats the ACL file as not being defined, which
means that no topic access is denied.  Although denying access to all topics
is not a useful configuration, this behaviour is unexpected and could lead
to access being incorrectly granted in some circumstances.  Affects versions
1.0 to 1.5.5 inclusive.

CVE-2018-12546: If a client publishes a retained message to a topic that
they have access to, and then their access to that topic is revoked, the
retained message will still be delivered to future subscribers.  This
behaviour may be undesirable in some applications, so a configuration option
check_retain_source has been introduced to enforce checking of the retained
message source on publish.

Add two upstream post-1.5.6 patches to fix a build error in the bridge code
when ADNS is enabled and when building with older toolchains not defaulting

package/xenomai: move arch restriction to Cobalt core, no restriction for Mercury

Xenomai has two mutually exclusive cores:
- Cobalt: dual-kernel approach: patched kernel + userland
- Mercury: only userland

In the Cobalt core, not all architectures are supported. This is the source
of the existing ARCH_SUPPORTS variable.

In the Mercury core, there is no imposed architecture restriction.

Rename the XENOMAI_ARCH_SUPPORTS flag to XENOMAI_COBALT_ARCH_SUPPORTS and
move its check from the Xenomai package to the Cobalt core.

Nevertheless, even for Mercury, there are some restrictions:
- pthread_atfork is used, which requires an MMU
- sync functions like __sync_sub_and_fetch and __sync_add_and_fetch are
  expected.

As the corresponding 'linux extension' selects Xenomai, we add the
MMU and sync dependencies there too. They may or may not already be covered
by XENOMAI_COBALT_ARCH_SUPPORTS flag.

core/pkg-infra: restore completeness of packages files lists

In commit 7fb6e782542f (core/instrumentation: shave minutes off the
build time), the built stampfile is used as a reference to detect files
installed by a package.

However, packages may install files keeping their mtime intact, and we
end up not detecting this. For example, the internal skeleton package
will install (e.g.) /etc/passwd with an mtime of when the file was
created in $(TOP_DIR), which could be the time the git repository was
checked out; that mtime is always older than the build stamp file, so
files installed by the skeleton package are never accounted for to that
package, or to any other package for that matters.

We switch to an alternate solution, which consists of storing some extra
metadata per file, so that we can more reasily detect modifications to
the files. Then we compare the state before the package is installed (by
reusing the existing list) and after the package is installed, compare
that to list any new file or modified files (in reality, ignoring
untouched and removed files). Finally, we store the file->package
association in the global list and store the new stat list as the global
list.

The format used for the .stat file is:

mtime:inode:perms:filetype:size,filename

docs/website: add page for the Buildroot Association

For about two years, a legal entity called "Buildroot Association" was
created in France to support the Buildroot project. Until fall 2018,
this legal entity has not been used. In fall 2018, we started using it
in order to receive donations from companies in order to organize the
Buildroot Developers Meeting that took place before the Embedded Linux
Conference Europe 2018 in Edinburgh.

This commit creates a new page on our web site that documents the
existence of this Buildroot Association, and details how to become a
member. Both individuals and companies can become members.

It is worth stating that the Buildroot Association does not control
the Buildroot project: it remains a fully open-source and
community-driven project. The Buildroot Association only serves as a
legal entity to handle donations and money needed to organize the
Buildroot Developers Meeting, and pay for a few expenses related to
the project (such as domain names).

package/mongodb: remove package

Fixes:
http://autobuild.buildroot.net/results/dd4/dd412fae45a84e44e7e6a49f8cdb124d0851c1df/

The mongodb version used (3.3.4) is no longer supported by upstream and
fails to build with openssl 1.1.1x.  On top of that it uses internal copies
of boost, pcre and zlib instead of the system ones.

Bumping the version to 3.4.19 (which is still supported until September
2019) has been tried, but it:

- No longer builds for 32bit ARM

- Doesn't build without extra patches, E.G.:
  https://git.openembedded.org/meta-openembedded/tree/meta-oe/recipes-support/mongodb/mongodb/0002-d_state.cpp-Add-missing-dependenncy-on-local_shardin.patch?h=rocko

- Doesn't build with the system version of boost (1.69.0)

- Also fails to build with openssl-1.1.1x

So it looks like mongodb needs to be bumped to the 3.6.x series (which
changes the license to the SSPL) - Or simply dropped.

weston: add weston-imx variant when using imx-gpu-viv

This variant contains various optimizations for i.MX processors.

For instance, on i.MX6/7 devices with GPU, the gl-renderer needs to be
enabled for the fbdev-backend which was removed from upstream weston
long time ago.

Also, weston-imx adds support for G2D which is enabled by default, this
patch makes sure to disable it when imx-gpu-g2d isn't selected.

The tag version rel_imx_4.9.51_8mq_ga proved to work fine on both
i.MX6Q/DL and i.MX8MQ processors.

Here are the commands used to start weston on i.MX6Q:
- Using 3D GPU (gl-renderer):
 # weston --tty=1 --device=/dev/fb0
- Using 2D GPU (G2D):
 # weston --tty=1 --device=/dev/fb0 --use-g2d=1

configs/pc_x86_64_efi: use a GPT partition table

Since all EFI-based systems support GPT, this commit changes
pc_x86_64_efi to use a GPT partition table. It shows an example of how
to craft a disk image with GPT partitioning instead of MBR. This is
achieved by means of a post-image script which uses
mkdosfs+mcopy+sfdisk, since genimage is unable to deal with GPT. Long
term, it would be ideal if genimage had GPT support, but until then,
this script shows how to achieve creating a GPT-based disk image.

The script was kept as simple as possible to make it easy to understand
and adapt for other purposes.

The root filesystem location is passed to the kernel by a partition
UUID, so it is possible to boot on QEMU, directly from the disk image,
or dump the image to a physical device.

system: allow selecting merged /usr along with custom rootfs skeleton

If the user is brave enough to use a custom rootfs skeleton then we must
not prevent using merged /usr too. Actually it is already possible to do
this, although indirectly, by selecting BR2_INIT_SYSTEMD.

Makefile: allow rootfs overlays to override symbolic links

Since commit 0db34529f48 we use rsync with the --keep-dirlinks option to
prevent overlays from accidentally overwriding /{usr,bin,sbin,lib} links
when BR2_ROOTFS_MERGED_USR option is enabled. Unfortunately this also
prevents replacing a symlink by a directory on purpose (e.g. /var/log,
to persist system logs).

Steps to reproduce:

- enable BR2_ROOTFS_MERGED_USR and BR2_PACKAGE_SKELETON_INIT_SYSV
- mkdir some_path/rootfs-overlay/var/log
- enable BR2_ROOTFS_OVERLAY="some_path/rootfs-overlay"
- run 'make'
- 'target/var/log' is still a symlink to '../tmp', not a directory

The --keep-dirlinks option can be dropped, since we run sanity checks
on overlays. Now the rsync invocation is identical to the SYSTEM_RSYNC
logic we have in system/system.mk, so use that variable.

Makefile: check rootfs overlays with BR2_ROOTFS_MERGED_USR enabled

Add a step to target-finalize that checks each rootfs overlay, following
the criteria established for custom skeletons and using the same script
uesd by skeleton-custom.mk.

Add a paragraph to the documentation clarifying that rootfs overlays
don't need to contain /bin, /lib or /sbin and must not contain them when
BR2_ROOTFS_MERGED_USR is enabled.
