Fixes the following security issues:
CVE-2020-14367: Insecure writing of pidfile
-------------------------------------------
When chronyd is configured to save the pidfile in a directory where the
chrony user has write permissions (e.g. /var/run/chrony - the default
since chrony-3.4), an attacker that compromised the chrony user account
could create a symbolic link at the location of the pidfile to make
chronyd starting with root privileges follow the symlink and write its
process ID to a file for which the chrony user doesn't have write
permissions, causing a denial of service, or data loss.
This issue was reported by Matthias Gerstner of SUSE.

python-numpy is an optional dependency since
545c1a1d3a
This dependency will raise the following build failure if python-numpy
is found on the host:
aarch64_be-linux-gnu-g++: ERROR: unsafe header/library path used in cross-compilation: '-I/usr/lib/python3/dist-packages/numpy/core/include'
because mjpg-streamer uses the python executable to retrieve the include
directory:

-- Found PythonInterp: /usr/bin/python3.5 (found version "3.5.3")
-- Found NUMPY: /usr/lib/python3/dist-packages/numpy/core/include
So disable python filter as well as cpp example while at it

This new runtime test is based on test_dropbear.py. The only required change
is to use "-oStrictHostKeyChecking=no" instead of "-y" to accept the new key.
Since the base test infra only provide a uClibc-ng toolchain, add a second
test using a glibc based internal toolchain.
For example, this allow to trigger the openssh 8.1p bug with glibc 2.31 [1].

Release notes:
https://dovecot.org/pipermail/dovecot-news/2020-August/000440.html
Fixes the following CVEs:
* CVE-2020-12100: Parsing mails with a large number of MIME parts could
have resulted in excessive CPU usage or a crash due to running out of
stack memory.
* CVE-2020-12673: Dovecot's NTLM implementation does not correctly check
message buffer size, which leads to reading past allocation which can
lead to crash.
* CVE-2020-10967: lmtp/submission: Issuing the RCPT command with an
address that has the empty quoted string as local-part causes the lmtp
service to crash.
* CVE-2020-12674: Dovecot's RPA mechanism implementation accepts
zero-length message, which leads to assert-crash later on.

In keepalived, ipset is only used when iptables support is
enabled. The configure.ac script is quite convoluted, but one can
clearly see:
AS_IF([test .$enable_iptables != .no],
[
... testing for iptables ...
if test $USE_IPTABLES = Yes; then
dnl ----[Check for ipset libraries]----
SAV_CPPFLAGS="$CPPFLAGS"
CPPFLAGS="$CPPFLAGS $kernelinc"
if test "${enable_libipset}" != no; then
... testing for libipset ...
fi
]
So, the libipset library is only tested and used if iptables is
enabled. This is also visible by the code that shows at the end of the
configure script which features are enabled:
echo "Use iptables : ${USE_IPTABLES}"
if test .$USE_IPTABLES = .Yes; then
echo "Use libipset : ${USE_LIBIPSET}"
fi
Once again, the libipset support only makes sense when iptables is
enabled.
However, the configure.ac script also has some logic to detect if a
--<something>-libipset option is passed while iptables is enabled:
AS_IF([test .$enable_iptables = .no],
AS_IF([test .$enable_libipset != .], [AC_MSG_ERROR([disable-libipset requires vrrp and iptables])])
)
The error message is quite misleading because it is in fact displayed
as soon as a --<something>-libipset is passed not just
--disable-libipset.
In the context of Buildroot, we are always passing a
--<something>-libipset, regardless of whether iptables support is
enabled or not, which makes the build error out:
configure: error: disable-libipset requires vrrp and iptables
This commit fixes that by enclosing the libipset logic inside the
iptables condition. When iptables is not available, we pass
--disable-iptables and that's it, nothing else is needed. When
iptables is available, we pass --enable-iptables *and*
--enable-libipset or --disable-libipset depending on the availability
of libipset.
This has been tested successfully with the following combinations:
- keepalived, without iptables or libipset
- keepalived, with iptables, but without libipset
- keepalived, without iptables, but with libipset. In this case
libipset is obviously not used.
- keepalived, with iptables and with libipset. Both are used. Note
that you will not see the keepalived binary linked with libipset.so
in "readelf -d" because keepalived dlopen()s the libipset.so
library by default.
