commit bc715ee4dbc5db462c59b9cfba92d31b3274fe3a upstream.
The function_graph_enter() function does the work of calling the function
graph hook function and the management of the shadow stack, simplifying the
work done in the architecture dependent prepare_ftrace_return().Have superh use the new code, and remove the shadow stack management as well as
having to set up the trace structure.This is needed to prepare for a fix of a design bug on how the curr_ret_stack
is used.Cc: Yoshinori Sato

Commit a0f97e06a43c ("kbuild: enable 'make CFLAGS=...' to add
additional options to CC") renamed CFLAGS to KBUILD_CFLAGS.Commit 222d394d30e7 ("kbuild: enable 'make AFLAGS=...' to add
additional options to AS") renamed AFLAGS to KBUILD_AFLAGS.Commit 06c5040cdb13 ("kbuild: enable 'make CPPFLAGS=...' to add
additional options to CPP") renamed CPPFLAGS to KBUILD_CPPFLAGS.For some reason, LDFLAGS was not renamed.
Using a well-known variable like LDFLAGS may result in accidental
override of the variable.Kbuild generally uses KBUILD_ prefixed variables for the internally
appended options, so here is one more conversion to sanitize the
naming convention.I did not touch Makefiles under tools/ since the tools build system
is a different world.Signed-off-by: Masahiro Yamada

Use new return type vm_fault_t for fault handler. For now, this is just
documenting that the function returns a VM_FAULT value rather than an
errno. Once all instances are converted, vm_fault_t will become a
distinct type.Ref-> commit 1c8f422059ae ("mm: change return type to vm_fault_t")
In this patch all the caller of handle_mm_fault() are changed to return

Many of the inc/dec ops are mandatory, but for most architectures inc/dec are
simply trivial wrappers around their corresponding add/sub ops.Let's make all the inc/dec ops optional, so that we can get rid of these
boilerplate wrappers.The instrumented atomics are updated accordingly.
There should be no functional change as a result of this patch.

Some of the atomics return the result of a test applied after the atomic
operation, and almost all architectures implement these as trivial
wrappers around the underlying atomic. Specifically:* _inc_and_test(v) is (_inc_return(v) == 0)
* _dec_and_test(v) is (_dec_return(v) == 0)
* _sub_and_test(i, v) is (_sub_return(i, v) == 0)
* _add_negative(i, v) is (_add_return(i, v) < 0)Rather than have these definitions duplicated in all architectures, with
minor inconsistencies in formatting and documentation, let's make these
operations optional, with default fallbacks as above. Implementations
must now provide a preprocessor symbol.The instrumented atomics are updated accordingly.
Both x86 and m68k have custom implementations, which are left as-is,
given preprocessor symbols to avoid being overridden.There should be no functional change as a result of this patch.

Several architectures these have a near-identical implementation based
on atomic_read() and atomic_cmpxchg() which we can instead define in
, so let's do so, using something close to the existing
x86 implementation with try_cmpxchg().Where an architecture provides its own atomic_fetch_add_unless(), it
must define a preprocessor symbol for it. The instrumented atomics are
updated accordingly.Note that arch/arc's existing atomic_fetch_add_unless() had redundant
barriers, as these are already present in its atomic_cmpxchg()
implementation.There should be no functional change as a result of this patch.

While __atomic_add_unless() was originally intended as a building-block
for atomic_add_unless(), it's now used in a number of places around the
kernel. It's the only common atomic operation named __atomic*(), rather
than atomic_*(), and for consistency it would be better named
atomic_fetch_add_unless().This lack of consistency is slightly confusing, and gets in the way of
scripting atomics. Given that, let's clean things up and promote it to
an official part of the atomics API, in the form of
atomic_fetch_add_unless().This patch converts definitions and invocations over to the new name,
including the instrumented version, using the following script:----
git grep -w __atomic_add_unless | while read line; do
sed -i '{s/\/atomic_fetch_add_unless/}' "${line%%:*}";
done
git grep -w __arch_atomic_add_unless | while read line; do
sed -i '{s/\/arch_atomic_fetch_add_unless/}' "${line%%:*}";
done
----Note that we do not have atomic{64,_long}_fetch_add_unless(), which will
be introduced by later patches.There should be no functional change as a result of this patch.

Clear current_kprobe and enable preemption in kprobe
even if pre_handler returns !0.This simplifies function override using kprobes.
Jprobe used to require to keep the preemption disabled and
keep current_kprobe until it returned to original function
entry. For this reason kprobe_int3_handler() and similar
arch dependent kprobe handers checks pre_handler result
and exit without enabling preemption if the result is !0.After removing the jprobe, Kprobes does not need to
keep preempt disabled even if user handler returns !0
anymore.But since the function override handler in error-inject
and bpf is also returns !0 if it overrides a function,
to balancing the preempt count, it enables preemption
and reset current kprobe by itself.That is a bad design that is very buggy. This fixes
such unbalanced preempt-count and current_kprobes setting
in kprobes, bpf and error-inject.Note: for powerpc and x86, this removes all preempt_disable
from kprobe_ftrace_handler because ftrace callbacks are
called under preempt disabled.Signed-off-by: Masami Hiramatsu

HAVE_CC_STACKPROTECTOR should be selected by architectures with stack
canary implementation. It is not about the compiler support.For the consistency with commit 050e9baa9dc9 ("Kbuild: rename
CC_STACKPROTECTOR[_STRONG] config variables"), remove 'CC_' from the
config symbol.I moved the 'select' lines to keep the alphabetical sorting.
