Fixes the following security issues:
- CVE-2019-19921: runc volume mount race condition with shared mounts
- CVE-2019-16884: runc through 1.0.0-rc8, as used in Docker through
19.03.2-ce and other products, allows AppArmor restriction bypass because
libcontainer/rootfs_linux.go incorrectly checks mount targets, and thus a
malicious Docker image can mount over a /proc directory.

Fixes CVE-2019-9755: An integer underflow issue exists in ntfs-3g 2017.3.23.
A local attacker could potentially exploit this by running /bin/ntfs-3g with
specially crafted arguments from a specially crafted directory to cause a
heap buffer overflow, resulting in a crash or the ability to execute
arbitrary code. In installations where /bin/ntfs-3g is a setuid-root
binary, this could lead to a local escalation of privileges.

In gcc 5.1.0, a change was introduced which causes internal search paths
inside the sysroot to be relative to 'lib64' rather than 'lib'. See [1] [2]
and [3].
For example for dtc:
LD convert-dtsv0

collect2: error: ld returned 1 exit status

In this case, crt1.o was searched for in following locations:

As can be seen above, all attempted paths contain 'lib64' as base,
instead of 'lib' or 'lib32', e.g.
.../sysroot/lib64/../lib32-fp/crt1.o
.../sysroot/lib64/crt1.o
This problem was detected on a gcc 7.x toolchain provided by Marvell as part
of their Octeon SDK. For this toolchain, here are the values of the paths
as detected by the Buildroot toolchain logic, for two different Octeon
processors:
- octeon2 (soft-float) (-mabi=n32 -march=octeon2):
SYSROOT_DIR=/opt/buildroot/output/host/opt/ext-toolchain/mips64-octeon-linux-gnu/sys-root/;
ARCH_SYSROOT_DIR=/opt/buildroot/output/host/opt/ext-toolchain/mips64-octeon-linux-gnu/sys-root/;
ARCH_SUBDIR=;
ARCH_LIB_DIR=lib32/octeon2;
SUPPORT_LIB_DIR=/opt/buildroot/output/host/opt/ext-toolchain/mips64-octeon-linux-gnu/lib32/octeon2/
- octeon3 (hard-float) (-mabi=n32 -march=octeon3):
SYSROOT_DIR=/opt/buildroot/output/host/opt/ext-toolchain/mips64-octeon-linux-gnu/sys-root/;
ARCH_SYSROOT_DIR=/opt/buildroot/output/host/opt/ext-toolchain/mips64-octeon-linux-gnu/sys-root/;
ARCH_SUBDIR=;
ARCH_LIB_DIR=lib32-fp;
SUPPORT_LIB_DIR=/opt/buildroot/output/host/opt/ext-toolchain/mips64-octeon-linux-gnu/lib32-fp/
For both cases (MIPS64n32) Buildroot created a symlink 'lib32->lib', from
SYSTEM_LIB_SYMLINK in system/system.mk. Additionally, the function
create_lib_symlinks in
toolchain/toolchain-external/pkg-toolchain-external.mk will use ARCH_LIB_DIR
and create an additional link $(ARCH_LIB_DIR)->lib.
For the Octeon3 case this thus results in the following symlinks (where the
'lib32' one is normally not needed):
lib32 -> lib/
lib32-fp -> lib/
Since the toolchain is searching based on a 'lib64' component, it will fail
to find its internal paths.
To solve the problem, we need to create an additional symlink 'lib64':
lib64 -> lib/

configure.ac contains a test using $ax_cv_check_cl_libcl:
if test "$build_modules" != 'no' || test "X$ax_cv_check_cl_libcl" != Xno; then
AC_MSG_RESULT([-------------------------------------------------------------])
AC_MSG_CHECKING([for libltdl])
But ax_cv_check_cl_libcl is only assigned a value (yes/no) if
--disable-opencl is NOT passed, as the assignment logic is inside a
conditional:
AC_ARG_ENABLE([opencl],
[AC_HELP_STRING([--disable-opencl],

[disable_opencl=$enableval],
[disable_opencl='yes'])
if test "$disable_opencl" = 'yes'; then
..
AC_CACHE_CHECK([for OpenCL library], [ax_cv_check_cl_libcl],
So configure errors out if --disable-opencl is passed on setups where
libltdl isn't available:

configure: error: in `/home/naourr/work/instance-0/output-1/build/imagemagick-7.0.8-59':
configure: error: libltdl is required for modules and OpenCL builds

egrep/fgrep are wrapper scripts, calling the grep binary with the correct
arguments.
The shell wrappers use the value of SHELL at build time as the shebang value
in these wrapper scripts, which in Buildroot points to /bin/bash.
The target may not have bash available, causing runtime errors.
As a fix, add a post-install hook to change this to /bin/sh.
If the target does not have /bin/sh, simply remove the aliases.

The meson script includes the full path to the python interpreter. In
deep build trees, this path can be more than 128 characters long, which
is the limit for how long a shebang may be.
Notice that this has been bumped to 256 since kerel 5.1, but the issue still
persists:
https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?id=6eb3c3d0a52dca337e327ae8868ca1f44a712e02
In older kernels, this limit was silently ignored, leading to potential
bugs, but newer kernels enforce that limit, and refuse to execve() the
script, returning with NOEXEC. Since the script is +x, the shell (any
bourne shell, as well as the C shell) will conclude from that situation that
they should interpret it as a shell script, which it obviously is not.
Fix the problem by replacing the shebang with a call to /usr/bin/env
which will redirect to the correct python3 interpreter found in the
PATH.
Note however that this means our meson installation can no longer be
called from outside of the meson-package infrastructure anymore (not
that we ever supported it before, but who knows what people may have
done in their br2-external), unless one does set the PATH to include
$(HOST_DIR)/bin/ earlier than a system-provided python3 would be found.

While the kernel is built for the target, the build may need various host
libraries depending on config (and kernel version), so use HOST_MAKE_ENV
instead of TARGET_MAKE_ENV.
In particular, this ensures that our host-pkgconf will look for host
libraries and not target ones.
Fixes building scripts/dtc for Buildroot configurations enabling libyaml and
host-pkgconf for kernels after commit 067c650c45 (dtc: Use pkg-config to
locate libyaml).
With this enabled, we can drop the PKG_CONFIG_* variables for the
_NEEDS_HOST_LIBELF conditional, as those are included in HOST_MAKE_ENV.

Pull some fixed applied after the release.
Disable the use of code under GPLv3 included in hwclock since v2.30. The
subject was discussed upstream[1] and it was decided that hwclock will
be made GPLv2-only again in v2.36, so do it in advance in Buildroot.
Meanwhile, be warned that all OS images selecting hwclock built with
Buildroot since commit 74235a6854 (util-linux: bump to version 2.30)
contain code under GPLv3, which imposes some technical difficulties to
include in embedded systems. For more information see GPLv3, Section 6,
"Conveying Non-Source Forms", and the definitions of User Product and

On 32-bit architectures, a malformed input to crypto/x509 or the ASN.1
parsing functions of golang.org/x/crypto/cryptobyte can lead to a panic.
The malformed certificate can be delivered via a crypto/tls connection to a
client, or to a server that accepts client certificates. net/http clients
can be made to crash by an HTTPS server, while net/http servers that accept
client certificates will recover the panic and are unaffected. Thanks to
Project Wycheproof for providing the test cases that led to the discovery of
this issue. The issue is CVE-2020-7919 and Go issue golang.org/issue/36837.

CMakeLists.txt contains a toolchain check:
if (${CMAKE_CXX_COMPILER_ID} STREQUAL "GNU")
if (${CMAKE_CXX_COMPILER_VERSION} VERSION_LESS "7.3.0")
message(FATAL_ERROR "GCC 7.3 or newer is required to build WebKit. Use a newer GCC version or Clang.")
endif ()
endif ()
So bump the toolchain dependency to >= GCC 7. The check is really about >=
7.3.0, but we do not have such detailed version checks. Given that GCC
7.3.0 was released in January 2018 (and 7.1.0 in May 2017), most external
GCC 7.x toolchains probably use >= 7.3.0.

When 'make' includes a new Makefile, it appends its path to the MAKEFILE_LIST
variable. From that variable, we construct a few set of derivative
variables:
pkgdir = $(dir $(lastword $(MAKEFILE_LIST)))
pkgname = $(lastword $(subst /, ,$(pkgdir)))
Essentially, pkgdir is the full directory where the package is located
(either relative to Buildroot's top directory for in-tree packages, or
absolute for packages in br2-external trees), while pkgname is the last
component of that directory.
pkgdir is in turn used to seed FOO_PKGDIR.
This all happens when we eventually call the package-generic infra,
later down in the file.
When they are parsed, the Makefiles for each linux-extensions are
appended to MAKEFILE_LIST, after the linux.mk one. But since they are
located in the same directory as the main linux.mk, the last component
of MAKEFILE_LIST, which is no longer the main linux.mk, will still yield
the correct values for the linux package.
This is a tough assumption we made there and then.
When we added the support for br2-external linux extensions, we where
very cautious to explicitly scan them from a directory named 'linux', so
that this would yield the correct package name.
And that worked well so far, until someone needed to build an older
kernel, for which our conditional patch is needed, and which just
failed:
/bin/bash: [...]/buildroot-external-linux-test/linux//0001-timeconst.pl-Eliminate-Perl-warning.patch.conditional: No such file or directory
When we scan linux extensions from a br2-external tree, the last
component of MAKEFILE_LIST is no longer in the same directory as the
main linux.mk, and thus the assumption above falls to pieces...
Again, when we added support for linux extensions from br2-external,
although we cared about the package name (pkgname), we completely missed
out on the package directory, and the LINUX_PKGDIR variable.
We do not have a very clean way out of this mess, but we have a nice
dirty trick: Scan the linux extensions from a br2-external tree before we
scan the in-tree ones. That way, the last component of MAKEFILE_LIST is
back to one that is in the same directory as the main linux.mk, and
we're back on tracks.
This is still very fragile, though, but short of a complete overhaul on
how packages are parsed and evaluated, this is the best we can come in
short order.

Signed-off-by: Peter Korsgaard <peter@korsgaard.com>
Qt5 has predefined optimization flags depending if you're building for
size, for debug etc. These flags are defined in
mkspecs/common/gcc-base.conf:
QMAKE_CFLAGS_OPTIMIZE = -O2
QMAKE_CFLAGS_OPTIMIZE_FULL = -O3
QMAKE_CFLAGS_OPTIMIZE_DEBUG = -Og
QMAKE_CFLAGS_OPTIMIZE_SIZE = -Os
Then, in the same file, they use them to set
QMAKE_CFLAGS_RELEASE/QMAKE_CXXFLAGS_RELEASE:
QMAKE_CFLAGS_RELEASE += $$QMAKE_CFLAGS_OPTIMIZE
QMAKE_CXXFLAGS_RELEASE += $$QMAKE_CFLAGS_RELEASE
At this point there is our chance to override QMAKE_CFLAGS_OPTIMIZE_* in
qmake.conf, but it's too late, because QMAKE_CFLAGS_RELEASE is already
set (i.e. -O2) so trying to add or remove QMAKE_CFLAGS_OPTIMIZE (that is
reset now on) from QMAKE_CLAGS_RELEASE in
common/features/default_post.prf won't work:
optimize_size {
!isEmpty(QMAKE_CFLAGS_OPTIMIZE):!isEmpty(QMAKE_CFLAGS_OPTIMIZE_SIZE) {
QMAKE_CFLAGS_RELEASE -= $$QMAKE_CFLAGS_OPTIMIZE
QMAKE_CXXFLAGS_RELEASE -= $$QMAKE_CFLAGS_OPTIMIZE
QMAKE_CFLAGS_RELEASE += $$QMAKE_CFLAGS_OPTIMIZE_SIZE
QMAKE_CXXFLAGS_RELEASE += $$QMAKE_CFLAGS_OPTIMIZE_SIZE
}
} else: optimize_full {
!isEmpty(QMAKE_CFLAGS_OPTIMIZE):!isEmpty(QMAKE_CFLAGS_OPTIMIZE_FULL) {
QMAKE_CFLAGS_RELEASE -= $$QMAKE_CFLAGS_OPTIMIZE
QMAKE_CXXFLAGS_RELEASE -= $$QMAKE_CFLAGS_OPTIMIZE
QMAKE_CFLAGS_RELEASE += $$QMAKE_CFLAGS_OPTIMIZE_FULL
QMAKE_CXXFLAGS_RELEASE += $$QMAKE_CFLAGS_OPTIMIZE_FULL
}
}
So let's reset:
QMAKE_CFLAGS_RELEASE
QMAKE_CFLAGS_DEBUG
QMAKE_CXXFLAGS_RELEASE
QMAKE_CXXFLAGS_DEBUG
in our qmake.conf since the only assignment done in
mkspecs/common/gcc-base.conf only regards optimization.
This package is also affected by BR2_TOOLCHAIN_HAS_GCC_BUG_90620 and
it's been worked around by appending -O0 to CFLAGS/CXXFLAGS. This bug
prevented workaround to work overriding optimization flags, so solving
this also solves workaround problem.
