Raise gcc version requirement to 4.9
I realize that we fairly recently raised it to 4.8, but the fact is, 4.9
is a much better minimum version to target.
We have a number of workarounds for actual bugs in pre-4.9 gcc versions
(including things like internal compiler errors on ARM), but we also
have some syntactic workarounds for lacking features.
In particular, raising the minimum to 4.9 means that we can now just
assume _Generic() exists, which is likely the much better replacement
for a lot of very convoluted built-time magic with conditionals on
sizeof and/or __builtin_choose_expr() with same_type() etc.
Using _Generic also means that you will need to have a very recent
version of 'sparse', but thats easy to build yourself, and much less of
a hassle than some old gcc version can be.
The latest (in a long string) of reasons for minimum compiler version
upgrades was commit

Second batch of perf tooling fixes for v5.8:
- Intel PT fixes for PEBS-via-PT with registers.
- Fixes for Intel PT python based GUI.
- Avoid duplicated sideband events with Intel PT in system wide tracing.
- Remove needless 'dummy' event from TUI menu, used when synthesizing
meta data events for pre-existing processes.
- Fix corner case segfault when pressing enter in a screen without
entries in the TUI for report/top.
- Fixes for time stamp handling in libtraceevent.
- Explicitly set utf-8 encoding in perf flamegraph.
- Update arch/x86/lib/memcpy_64.S copy used in 'perf bench mem memcpy',
silencing perf build warning.

Test results:
The first ones are container based builds of tools/perf with and without libelf
support. Where clang is available, it is also used to build perf with/without
libelf, and building with LIBCLANGLLVM=1 (built-in clang) with gcc and clang
when clang and its devel libraries are installed.
The objtool and samples/bpf/ builds are disabled now that I'm switching from
using the sources in a local volume to fetching them from a http server to
build it inside the container, to make it easier to build in a container cluster.
Those will come back later.
Several are cross builds, the ones with -x-ARCH and the android one, and those
may not have all the features built, due to lack of multi-arch devel packages,
available and being used so far on just a few, like
debian:experimental-x-{arm64,mipsel}.
The 'perf test' one will perform a variety of tests exercising
tools/perf/util/, tools/lib/{bpf,traceevent,etc}, as well as run perf commands
with a variety of command line event specifications to then intercept the
sys_perf_event syscall to check that the perf_event_attr fields are set up as
expected, among a variety of other unit tests.
Then there is the 'make -C tools/perf build-test' ones, that build tools/perf/
with a variety of feature sets, exercising the build with an incomplete set of
features as well as with a complete one. It is planned to have it run on each
of the containers mentioned above, using some container orchestration
infrastructure. Get in contact if interested in helping having this in place.
Some of the most recent, experimental distros are failing, fixes will be
provided, but those gcc/clang versions are not yet in general use and some
are related to linking with libllvm, not the default build.

perf report TUI: Remove needless 'dummy' event from menu
Fixing the common case of: perf record perf report And getting just the cycles events. We now have a 'dummy' event to get perf metadata events that take place while we synthesize metadata records for pre-existing processes by traversing procfs, so we always have this extra 'dummy' evsel, but we don't have to offer it as there will be no samples on it, remove this distraction.

perf intel-pt: Fix displaying PEBS-via-PT with registers
After recording PEBS-via-PT, perf script will not accept 'iregs' field e.g.
# perf record -c 10000 -e '{intel_pt/branch=0/,branch-loads/aux-output/ppp}' -I -- ls -l
...
[ perf record: Woken up 1 times to write data ]
[ perf record: Captured and wrote 0.062 MB perf.data ]
# ./perf script --itrace=eop -F+iregs
Samples for 'dummy:u' event do not have IREGS attribute set. Cannot print 'iregs' field.
Fix by using allow_user_set, which is true when recording AUX area data.

perf intel-pt: Fix recording PEBS-via-PT with registers
When recording PEBS-via-PT, the kernel will not accept the intel_pt
event with register sampling e.g.
# perf record --kcore -c 10000 -e '{intel_pt/branch=0/,branch-loads/aux-output/ppp}' -I -- ls -l
Error:
intel_pt/branch=0/: PMU Hardware doesn't support sampling/overflow-interrupts. Try 'perf stat'
Fix by suppressing register sampling on the intel_pt evsel.
Committer notes:
Adrian informed that this is only available from Tremont onwards, so on
older processors the error continues the same as before.

perf report TUI: Fix segmentation fault in perf_evsel__hists_browse()
The segmentation fault can be reproduced as following steps:
1) Executing perf report in tui.
2) Typing '/xxxxx' to filter the symbol to get nothing matched.
3) Pressing enter with no entry selected.
Then it will report a segmentation fault.
It is caused by the lack of check of browser->he_selection when
accessing it's member res_samples in perf_evsel__hists_browse().
These processes are meaningful for specified samples, so we can skip
these when nothing is selected.

A series of fixes for x86:
- Reset MXCSR in kernel_fpu_begin() to prevent using a stale user space
value.
- Prevent writing MSR_TEST_CTRL on CPUs which are not explicitly
whitelisted for split lock detection. Some CPUs which do not support
it crash even when the MSR is written to 0 which is the default value.
- Fix the XEN PV fallout of the entry code rework
- Fix the 32bit fallout of the entry code rework
- Add more selftests to ensure that these entry problems don't come back.
- Disable 16 bit segments on XEN PV. It's not supported because XEN PV
does not implement ESPFIX64

selftests/x86: Consolidate and fix get/set_eflags() helpers
There are several copies of get_eflags() and set_eflags() and they all are buggy. Consolidate them and fix them. The fixes are: Add memory clobbers. These are probably unnecessary but they make sure that the compiler doesn't move something past one of these calls when it shouldn't. Respect the redzone on x86_64. There has no failure been observed related to this, but it's definitely a bug.

Peter Zijlstra says:
These patches address a number of instrumentation issues that were found after
the x86/entry overhaul. When combined with rcu/urgent and objtool/urgent, these
patches make UBSAN/KASAN/KCSAN happy again.
Part of making this all work is bumping the minimum GCC version for KASAN
builds to gcc-8.3, the reason for this is that the __no_sanitize_address
function attribute is broken in GCC releases before that.
No known GCC version has a working __no_sanitize_undefined, however because the
only noinstr violation that results from this happens when an UB is found, we
treat it like WARN. That is, we allow it to violate the noinstr rules in order
to get the warning out.

Pull arm64 fixes from Will Deacon:
"The big fix here is to our vDSO sigreturn trampoline as, after a
painfully long stint of debugging, it turned out that fixing some of
our CFI directives in the merge window lit up a bunch of logic in
libgcc which has been shown to SEGV in some cases during asynchronous
pthread cancellation.
It looks like we can fix this by extending the directives to restore
most of the interrupted register state from the sigcontext, but it's
risky and hard to test so we opted to remove the CFI directives for
now and rely on the unwinder fallback path like we used to.

kunit: kunit_tool: Fix invalid result when build fails
When separating out different phases of running tests[1] (build/exec/parse/etc), the format of the KunitResult tuple changed (adding an elapsed_time variable). This is not populated during a build failure, causing kunit.py to crash. This fixes [1] to probably populate the result variable, causing a failing build to be reported properly.

bpf: tcp: bpf_cubic: fix spurious HYSTART_DELAY exit upon drop in min RTT
Apply the fix from:
"tcp_cubic: fix spurious HYSTART_DELAY exit upon drop in min RTT"
to the BPF implementation of TCP CUBIC congestion control.
Repeating the commit description here for completeness:
Mirja Kuehlewind reported a bug in Linux TCP CUBIC Hystart, where
Hystart HYSTART_DELAY mechanism can exit Slow Start spuriously on an
ACK when the minimum rtt of a connection goes down. From inspection it
is clear from the existing code that this could happen in an example
like the following:
o The first 8 RTT samples in a round trip are 150ms, resulting in a
curr_rtt of 150ms and a delay_min of 150ms.
o The 9th RTT sample is 100ms. The curr_rtt does not change after the
first 8 samples, so curr_rtt remains 150ms. But delay_min can be
lowered at any time, so delay_min falls to 100ms. The code executes
the HYSTART_DELAY comparison between curr_rtt of 150ms and delay_min
of 100ms, and the curr_rtt is declared far enough above delay_min to
force a (spurious) exit of Slow start.
The fix here is simple: allow every RTT sample in a round trip to
lower the curr_rtt.

letter explaining the problem:
A crash happened on ppc64le when running ltp network tests triggered by
"rmmod iptable_mangle".
See previous discussion in this thread:
https://lists.openwall.net/netdev/2020/06/03/161 .
In the crash I found in iptable_mangle_hook() that
state->net->ipv4.iptable_mangle=NULL causing a NULL pointer dereference.
net->ipv4.iptable_mangle is set to NULL in +iptable_mangle_net_exit() and
called when ip_mangle modules is unloaded. A rmmod task was found running
in the crash dump. A 2nd crash showed the same problem when running
"rmmod iptable_filter" (net->ipv4.iptable_filter=NULL).
To fix this I added .pre_exit hook in all iptable_foo.c. The pre_exit will
un-register the underlying hook and exit would do the table freeing. The
netns core does an unconditional +synchronize_rcu after the pre_exit hooks
insuring no packets are in flight that have picked up the pointer before
completing the un-register.
These patches include changes for both iptables and ip6tables.
We tested this fix with ltp running iptables01.sh and iptables01.sh -6 a
loop for 72 hours.
4) Add a selftest for conntrack helper assignment, from Florian Westphal.

selftests: netfilter: add test case for conntrack helper assignment
check that 'nft ... ct helper set <foo>' works:
1. configure ftp helper via nft and assign it to
connections on port 2121
2. check with 'conntrack -L' that the next connection
has the ftp helper attached to it.
Also add a test for auto-assign (old behaviour).

Fixes all over the place. This includes a couple of tests that I would normally defer, but since they have already been helpful in catching some bugs, don't build for any users at all, and having them upstream makes life easier for everyone, I think it's ok even at this late stage.

kselftest: arm64: Remove redundant clean target
The arm64 signal tests generate warnings during build since both they and the toplevel lib.mk define a clean target: Makefile:25: warning: overriding recipe for target 'clean' ../../lib.mk:126: warning: ignoring old recipe for target 'clean' Since the inclusion of lib.mk is in the signal Makefile there is no situation where this warning could be avoided so just remove the redundant clean target.

wireguard: device: avoid circular netns references
Before, we took a reference to the creating netns if the new netns was
different. This caused issues with circular references, with two
wireguard interfaces swapping namespaces. The solution is to rather not
take any extra references at all, but instead simply invalidate the
creating netns pointer when that netns is deleted.
In order to prevent this from happening again, this commit improves the
rough object leak tracking by allowing it to account for created and
destroyed interfaces, aside from just peers and keys. That then makes it
possible to check for the object leak when having two interfaces take a
reference to each others' namespaces.
