Fixes the following security issues:
- CVE-2020-13254: Potential data leakage via malformed memcached keys
In cases where a memcached backend does not perform key validation,
passing malformed cache keys could result in a key collision, and
potential data leakage. In order to avoid this vulnerability, key
validation is added to the memcached cache backends.
- CVE-2020-13596: Possible XSS via admin ForeignKeyRawIdWidget
Query parameters for the admin ForeignKeyRawIdWidget were not properly URL
encoded, posing an XSS attack vector. ForeignKeyRawIdWidget now ensures
query parameters are correctly URL encoded.

Changes since 1.63:
- 1.64 2020-04-11 Fixed error in definitions of BCM2835_AUX_SPI_STAT_TX_LVL
and BCM2835_AUX_SPI_STAT_RX_LVL
- 1.65, 1.66 2020-04-16 Added support for use of capability cap_sys_rawio
to determine if access to /dev/mem is available for non-root users
That latter part (using capabilities) is not supported, because it is
broken upstream (the code is messed up using two similar #defines to
test and enable it; messy...) Since it previously required root access
to work, and still does now, this is not a regression, so do not add
support for capablities.

Although those patches were properly dropped when the origianl bump was
applied to the next branch (commit 4675c7d441), both net and master also
had a commit that moved the patches around when the csku fork was
removed (commit 58af9a70cc and 20f45029cc, respectively).
This seemed to have caused some confusion with git-merge, though, and
the y re-appeared after the merge.

The soon-to-be-released linux 5.7 has changed the way it detects the
ability of gcc to use plugins, when it dropped support for gcc 4.7 or
older [0].
To detect the ability to use gcc plugins, the kernel has to check
whether the host gcc is capable enough to build them.
When we call one of the configurator for the Linux kernel, we explicitly
pass a value of HOSTCC=$(HOSTCC_NOCCACHE), because there might be a
discrepancy between the ncurses headers and libraries as found by the
Linux kconfig build [1] [2].
But then, when we build the kernel, we pass another value to use [3]
HOSTCC="$(HOSTCC) $(HOST_CFLAGS) $(HOST_LDFLAGS)" which boils down to
roughly: gcc -I.../host/include -L.../host/lib -Wl,-rpath,.../host/lib
This is needed so that at build time, the kernel can build host tools
that link with our openssl et al.
So, the two HOSTCC we pass to the kernel may have different behaviours.
For example, on a machine where gmp is missing in the system, it is
available in $(O)/host/ when using an internal toolchain (and under a
few other conditions).
In that case, when configuring the kernel, it decides that the host
compiler can't build plugins, so the dependencies of CONFIG_GCC_PLUGINS
are not met, and that option is not present in the linux' .config file
(neither as "=y" nor as "is not set"). But then, when we build the
kernel, the host compiler suddenly becomes capable of building the
plugins, and the internal syncconfig run by the kernel will notice that
the dependencies of CONFIG_GCC_PLUGINS are now met, and that the user
shall decide on its value. And this blocks a build on an interactive
console (abbreviated):
* Restart config...
* GCC plugins
GCC plugins (GCC_PLUGINS) [Y/n/?] (NEW) _
But most problematic is the behaviour when run in a shell that is not
interactiove (e.g. a CI job or such) (abbreviated):
* Restart config...
* GCC plugins
GCC plugins (GCC_PLUGINS) [Y/n/?] (NEW)
Error in reading or end of file.
Generate some entropy during boot and runtime (GCC_PLUGIN_LATENT_ENTROPY) [N/y/?] (NEW)
Error in reading or end of file.
Randomize layout of sensitive kernel structures (GCC_PLUGIN_RANDSTRUCT) [N/y/?] (NEW)
Error in reading or end of file.
* Memory initialization
Initialize kernel stack variables at function entry
> 1. no automatic initialization (weakest) (INIT_STACK_NONE)
2. zero-init structs marked for userspace (weak) (GCC_PLUGIN_STRUCTLEAK_USER) (NEW)
3. zero-init structs passed by reference (strong) (GCC_PLUGIN_STRUCTLEAK_BYREF) (NEW)
4. zero-init anything passed by reference (very strong) (GCC_PLUGIN_STRUCTLEAK_BYREF_ALL) (NEW)
choice[1-4?]:
Error in reading or end of file.
Poison kernel stack before returning from syscalls (GCC_PLUGIN_STACKLEAK) [N/y/?] (NEW)
Error in reading or end of file.
Enable heap memory zeroing on allocation by default (INIT_ON_ALLOC_DEFAULT_ON) [N/y/?] n
Enable heap memory zeroing on free by default (INIT_ON_FREE_DEFAULT_ON) [N/y/?] n
The most obvious and simple solution would be to unconditionally disable
gcc plugins altogether, in the KCONFIG_FIXUP hook. But that can't work
either, because after applying the fixups, we call olddefconfig (or the
likes) with the incapable HOSTCC, so the disabled option would be removed
anyway, and we'd be back to square one.
So, in addition to the above, we also forcibly hack the same call just
before actually building the kernel.
Note that the two are needed: the one in the fixups is needed for those
that have a system that already allows building gcc plugins, and the
second is needed in the other case, where the system does not allow it
but would work with our additional headers and libs in $(O)/host/. The
two ensure there is a very similar experience in the two situations.
Forcibly disabling the use of gcc plugins is not a regression on our
side: it has never been possible to do so so far. We're now making sure
that can't work by accident.

While cross-compiling, qt5webengine is building a host tool, 'gn', and

/lib64/ld-linux-x86-64.so.2 (0x00007f48a3c53000)
Not all ditributions have the static libraries installed by default; for
example, on Fedora, libstdc++-static is not installed on a fresh system,
leading to build issues:

The current script (S51sysrepo-plugind) is not able to stop the daemon.
Possible options to fix the problem:
A) By adding the "-m -p $PIDFILE" option to start the pid file will be
created but it will not contain the correct PID used by the daemon.
This is obviously because the daemon forks.
B) By not starting the daemon in background (sysrepo-plugind -d) and
let do it by start-stop-daemon with "-b" option. But then the log
messages of the daemon will not longer ends in the syslog but to stderr.
C) Start the daemon without a pidfile and stop the daemon with the
"-x" option.
The only valid option is C to fix that.

- Fix CVE-2020-11739: An issue was discovered in Xen through 4.13.x,
allowing guest OS users to cause a denial of service or possibly gain
privileges because of missing memory barriers in read-write unlock
paths. The read-write unlock paths don't contain a memory barrier. On
Arm, this means a processor is allowed to re-order the memory access
with the preceding ones. In other words, the unlock may be seen by
another processor before all the memory accesses within the "critical"
section. As a consequence, it may be possible to have a writer executing
a critical section at the same time as readers or another writer. In
other words, many of the assumptions (e.g., a variable cannot be
modified after a check) in the critical sections are not safe anymore.
The read-write locks are used in hypercalls (such as grant-table ones),
so a malicious guest could exploit the race. For instance, there is a
small window where Xen can leak memory if XENMAPSPACE_grant_table is
used concurrently. A malicious guest may be able to leak memory, or
cause a hypervisor crash resulting in a Denial of Service (DoS).
Information leak and privilege escalation cannot be excluded.
- Fix CVE-2020-11740: An issue was discovered in xenoprof in Xen through
4.13.x, allowing guest OS users (without active profiling) to obtain
sensitive information about other guests. Unprivileged guests can
request to map xenoprof buffers, even if profiling has not been enabled
for those guests. These buffers were not scrubbed.
- Fix CVE-2020-11741: An issue was discovered in xenoprof in Xen through
4.13.x, allowing guest OS users (with active profiling) to obtain
sensitive information about other guests, cause a denial of service, or
possibly gain privileges. For guests for which "active" profiling was
enabled by the administrator, the xenoprof code uses the standard Xen
shared ring structure. Unfortunately, this code did not treat the guest
as a potential adversary: it trusts the guest not to modify buffer size
information or modify head / tail pointers in unexpected ways. This can
crash the host (DoS). Privilege escalation cannot be ruled out.
- Fix CVE-2020-11742: An issue was discovered in Xen through 4.13.x,
allowing guest OS users to cause a denial of service because of bad
continuation handling in GNTTABOP_copy. Grant table operations are
expected to return 0 for success, and a negative number for errors. The
fix for CVE-2017-12135 introduced a path through grant copy handling
where success may be returned to the caller without any action taken. In
particular, the status fields of individual operations are left
uninitialised, and may result in errant behaviour in the caller of
GNTTABOP_copy. A buggy or malicious guest can construct its grant table
in such a way that, when a backend domain tries to copy a grant, it hits
the incorrect exit path. This returns success to the caller without
doing anything, which may cause crashes or other incorrect behaviour.
- Fix CVE-2020-11743: An issue was discovered in Xen through 4.13.x,
allowing guest OS users to cause a denial of service because of a bad
error path in GNTTABOP_map_grant. Grant table operations are expected to
return 0 for success, and a negative number for errors. Some misplaced
brackets cause one error path to return 1 instead of a negative value.
The grant table code in Linux treats this condition as success, and
proceeds with incorrectly initialised state. A buggy or malicious guest
can construct its grant table in such a way that, when a backend domain
tries to map a grant, it hits the incorrect error path. This will crash
a Linux based dom0 or backend domain.
