cee0aa0c31 ANDROID: arm64: add __va_function
With CFI, the compiler replaces function references with pointers
to the CFI jump table. This breaks passing these addresses to
code running at EL2, where the jump tables are not valid. Add a
__va_function macro similarly to the earlier __pa_function to take
address of the actual function in inline assembly and use that in
kvm_ksym_ref instead.

030d374eb9 arm64/bpf: don't allocate BPF JIT programs in module memory
The arm64 module region is a 128 MB region that is kept close to
the core kernel, in order to ensure that relative branches are
always in range. So using the same region for programs that do
not have this restriction is wasteful, and preferably avoided.

Now that the core BPF JIT code permits the alloc/free routines to
be overridden, implement them by vmalloc()/vfree() calls from a
dedicated 128 MB region set aside for BPF programs. This ensures
that BPF programs are still in branching range of each other, which
is something the JIT currently depends upon (and is not guaranteed
when using module_alloc() on KASLR kernels like we do currently).
It also ensures that placement of BPF programs does not correlate
with the placement of the core kernel or modules, making it less
likely that leaking the former will reveal the latter.

This also solves an issue under KASAN, where shadow memory is
needlessly allocated for all BPF programs (which don't require KASAN
shadow pages since they are not KASAN instrumented)

1db3ea5127 BACKPORT: arm64: kasan: fix page_alloc tagging with DEBUG_VIRTUAL
When CONFIG_DEBUG_VIRTUAL is enabled, the default page_to_virt() macro
implementation from include/linux/mm.h is used. That definition doesn't
account for KASAN tags, which leads to no tags on page_alloc allocations.

Provide an arm64-specific definition for page_to_virt() when
CONFIG_DEBUG_VIRTUAL is enabled that takes care of KASAN tags.

a8ef2a2913 ANDROID: arm64: add __pa_function
We use non-canonical CFI jump tables with CONFIG_CFI_CLANG, which
means the compiler replaces function address references with the
address of the function's CFI jump table entry. This results in
__pa_symbol(function) returning the physical address of the jump
table entry, which can lead to address space confusion since the
jump table points to a virtual address.

This change adds a __pa_function macro, which uses inline assembly
to take the actual function address instead.

(Upstream commit 597399d0cb91d049fcb78fb45c7694771b583bb7).

Sign-extending TTBR1 addresses when converting to an untagged address
breaks the documented POSIX semantics for mlock() in some obscure error
cases where we end up returning -EINVAL instead of -ENOMEM as a direct
result of rewriting the upper address bits.

Rework the untagged_addr() macro to preserve the upper address bits for
TTBR1 addresses and only clear the tag bits for user addresses. This
matches the behaviour of the 'clear_address_tag' assembly macro, so
rename that and align the implementations at the same time so that they
use the same instruction sequences for the tag manipulation.

(Upstream commit 7732d20a160c76006c7fe7bca5178aea6af1d2e8).

When CONFIG_KASAN_SW_TAGS=n, set_tag() is compiled away. GCC throws a
warning,

mm/kasan/common.c: In function '__kasan_kmalloc':
mm/kasan/common.c:464:5: warning: variable 'tag' set but not used
[-Wunused-but-set-variable]
  u8 tag = 0xff;
     ^~~

Fix it by making __tag_set() a static inline function the same as
arch_kasan_set_tag() in mm/kasan/kasan.h for consistency because there
is a macro in arch/arm64/include/asm/kasan.h,

 #define arch_kasan_set_tag(addr, tag) __tag_set(addr, tag)

However, when CONFIG_DEBUG_VIRTUAL=n and CONFIG_SPARSEMEM_VMEMMAP=y,
page_to_virt() will call __tag_set() with incorrect type of a
parameter, so fix that as well. Also, still let page_to_virt() return
"void *" instead of "const void *", so will not need to add a similar
cast in lowmem_page_address().

14d0bfec3f UPSTREAM: arm64: untag user pointers in access_ok and __uaccess_mask_ptr
(Upstream commit 2b835e24b5c6f9c633ff51973581ee7ca7b3e8ec).

This patch is a part of a series that extends kernel ABI to allow to pass
tagged user pointers (with the top byte set to something else other than
0x00) as syscall arguments.

copy_from_user (and a few other similar functions) are used to copy data
from user memory into the kernel memory or vice versa. Since a user can
provided a tagged pointer to one of the syscalls that use copy_from_user,
we need to correctly handle such pointers.

Do this by untagging user pointers in access_ok and in __uaccess_mask_ptr,
before performing access validity checks.

Note, that this patch only temporarily untags the pointers to perform the
checks, but then passes them as is into the kernel internals.

f46851e627 BACKPORT: kasan: remove use after scope bugs detection.
(Upstream commit 7771bdbbfd3d6f204631b6fd9e1bbc30cd15918e).

Use after scope bugs detector seems to be almost entirely useless for
the linux kernel.  It exists over two years, but I've seen only one
valid bug so far [1].  And the bug was fixed before it has been
reported.  There were some other use-after-scope reports, but they were
false-positives due to different reasons like incompatibility with
structleak plugin.

This feature significantly increases stack usage, especially with GCC <
9 version, and causes a 32K stack overflow.  It probably adds
performance penalty too.

Given all that, let's remove use-after-scope detector entirely.

While preparing this patch I've noticed that we mistakenly enable
use-after-scope detection for clang compiler regardless of
CONFIG_KASAN_EXTRA setting.  This is also fixed now.

be21fa3044 UPSTREAM: kasan, mm, arm64: tag non slab memory allocated via pagealloc
(Upstream commit 2813b9c0296259fb11e75c839bab2d958ba4f96c).

Tag-based KASAN doesn't check memory accesses through pointers tagged with
0xff.  When page_address is used to get pointer to memory that corresponds
to some page, the tag of the resulting pointer gets set to 0xff, even
though the allocated memory might have been tagged differently.

For slab pages it's impossible to recover the correct tag to return from
page_address, since the page might contain multiple slab objects tagged
with different values, and we can't know in advance which one of them is
going to get accessed.  For non slab pages however, we can recover the tag
in page_address, since the whole page was marked with the same tag.

This patch adds tagging to non slab memory allocated with pagealloc.  To
set the tag of the pointer returned from page_address, the tag gets stored
to page->flags when the memory gets allocated.

(Upstream commit 3c9e3aa11094e821aff4a8f6812a6e032293dbc0).

This commit adds a few helper functions, that are meant to be used to work
with tags embedded in the top byte of kernel pointers: to set, to get or
to reset the top byte.

b32b4dfdb2 UPSTREAM: arm64: move untagged_addr macro from uaccess.h to memory.h
(Upstream commit 9c23f84723d2bb5611a973f56f0952fa74f048f3).

Move the untagged_addr() macro from arch/arm64/include/asm/uaccess.h
to arch/arm64/include/asm/memory.h to be later reused by KASAN.

Also make the untagged_addr() macro accept all kinds of address types
(void *, unsigned long, etc.). This allows not to specify type casts in
each place where the macro is used. This is done by using __typeof__.

(Upstream commit b2f557eae9ed0ab2b612ce9ce7e3f06174a83e76).

Tag-based KASAN uses 1 shadow byte for 16 bytes of kernel memory, so it
requires 1/16th of the kernel virtual address space for the shadow memory.

This commit sets KASAN_SHADOW_SCALE_SHIFT to 4 when the tag-based KASAN
mode is enabled.

8f183b3323 arm64: kasan: Increase stack size for KASAN_EXTRA
[ Upstream commit 6e8830674ea77f57d57a33cca09083b117a71f41 ]

If the kernel is configured with KASAN_EXTRA, the stack size is
increased significantly due to setting the GCC -fstack-reuse option to
"none" [1]. As a result, it can trigger a stack overrun quite often with
32k stack size compiled using GCC 8. For example, this reproducer

  https://github.com/linux-test-project/ltp/blob/master/testcases/kernel/syscalls/madvise/madvise06.c

can trigger a "corrupted stack end detected inside scheduler" very
reliably with CONFIG_SCHED_STACK_END_CHECK enabled. There are other
reports at:

  https://lore.kernel.org/lkml/1542144497.12945.29.camel@gmx.us/
  https://lore.kernel.org/lkml/721E7B42-2D55-4866-9C1A-3E8D64F33F9C@gmx.us/

There are just too many functions that could have a large stack with
KASAN_EXTRA due to large local variables that have been called over and
over again without being able to reuse the stacks. Some noticiable ones
are,

size
7536 shrink_inactive_list
7440 shrink_page_list
6560 fscache_stats_show
3920 jbd2_journal_commit_transaction
3216 try_to_unmap_one
3072 migrate_page_move_mapping
3584 migrate_misplaced_transhuge_page
3920 ip_vs_lblcr_schedule
4304 lpfc_nvme_info_show
3888 lpfc_debugfs_nvmestat_data.constprop

There are other 49 functions over 2k in size while compiling kernel with
"-Wframe-larger-than=" on this machine. Hence, it is too much work to
change Makefiles for each object to compile without
-fsanitize-address-use-after-scope individually.

e48d53a91f arm64: KVM: Add support for Stage-2 control of memory types and cacheability
Up to ARMv8.3, the combinaison of Stage-1 and Stage-2 attributes
results in the strongest attribute of the two stages.  This means
that the hypervisor has to perform quite a lot of cache maintenance
just in case the guest has some non-cacheable mappings around.

ARMv8.4 solves this problem by offering a different mode (FWB) where
Stage-2 has total control over the memory attribute (this is limited
to systems where both I/O and instruction fetches are coherent with
the dcache). This is achieved by having a different set of memory
attributes in the page tables, and a new bit set in HCR_EL2.

On such a system, we can then safely sidestep any form of dcache
management.

2dd8a62c64 linux/const.h: move UL() macro to include/linux/const.h
ARM, ARM64 and UniCore32 duplicate the definition of UL():

  #define UL(x) _AC(x, UL)

This is not actually arch-specific, so it will be useful to move it to a
common header.  Currently, we only have the uapi variant for
linux/const.h, so I am creating include/linux/const.h.

I also added _UL(), _ULL() and ULL() because _AC() is mostly used in
the form either _AC(..., UL) or _AC(..., ULL).  I expect they will be
replaced in follow-up cleanups.  The underscore-prefixed ones should
be used for exported headers.

Pull arm64 updates from Will Deacon:
 "The big highlight is support for the Scalable Vector Extension (SVE)
  which required extensive ABI work to ensure we don't break existing
  applications by blowing away their signal stack with the rather large
  new vector context (<= 2 kbit per vector register). There's further
  work to be done optimising things like exception return, but the ABI
  is solid now.

  Much of the line count comes from some new PMU drivers we have, but
  they're pretty self-contained and I suspect we'll have more of them in
  future.

  Plenty of acronym soup here:

   - initial support for the Scalable Vector Extension (SVE)

   - improved handling for SError interrupts (required to handle RAS
     events)

   - enable GCC support for 128-bit integer types

   - remove kernel text addresses from backtraces and register dumps

   - use of WFE to implement long delay()s

   - ACPI IORT updates from Lorenzo Pieralisi

   - perf PMU driver for the Statistical Profiling Extension (SPE)

b02faed15d arm64: Use larger stacks when KASAN is selected
AddressSanitizer instrumentation can significantly bloat the stack, and
with GCC 7 this can result in stack overflows at boot time in some
configurations.

We can avoid this by doubling our stack size when KASAN is in use, as is
already done on x86 (and has been since KASAN was introduced).
Regardless of other patches to decrease KASAN's stack utilization,
kernels built with KASAN will always require more stack space than those
built without, and we should take this into account.

ILP32 series [1] introduces the dependency on <asm/is_compat.h> for
TASK_SIZE macro. Which in turn requires <asm/thread_info.h>, and
<asm/thread_info.h> include <asm/memory.h>, giving a circular dependency,
because TASK_SIZE is currently located in <asm/memory.h>.

In other architectures, TASK_SIZE is defined in <asm/processor.h>, and
moving TASK_SIZE there fixes the problem.

872d8327ce arm64: add VMAP_STACK overflow detection
This patch adds stack overflow detection to arm64, usable when vmap'd stacks
are in use.

Overflow is detected in a small preamble executed for each exception entry,
which checks whether there is enough space on the current stack for the general
purpose registers to be saved. If there is not enough space, the overflow
handler is invoked on a per-cpu overflow stack. This approach preserves the
original exception information in ESR_EL1 (and where appropriate, FAR_EL1).

Task and IRQ stacks are aligned to double their size, enabling overflow to be
detected with a single bit test. For example, a 16K stack is aligned to 32K,
ensuring that bit 14 of the SP must be zero. On an overflow (or underflow),
this bit is flipped. Thus, overflow (of less than the size of the stack) can be
detected by testing whether this bit is set.

The overflow check is performed before any attempt is made to access the
stack, avoiding recursive faults (and the loss of exception information
these would entail). As logical operations cannot be performed on the SP
directly, the SP is temporarily swapped with a general purpose register
using arithmetic operations to enable the test to be performed.

This gives us a useful error message on stack overflow, as can be trigger with
the LKDTM overflow test:

[  305.388749] lkdtm: Performing direct entry OVERFLOW

e3067861ba arm64: add basic VMAP_STACK support
This patch enables arm64 to be built with vmap'd task and IRQ stacks.

As vmap'd stacks are mapped at page granularity, stacks must be a multiple of
PAGE_SIZE. This means that a 64K page kernel must use stacks of at least 64K in
size.

To minimize the increase in Image size, IRQ stacks are dynamically allocated at
boot time, rather than embedding the boot CPU's IRQ stack in the kernel image.

8018ba4edf arm64: move SEGMENT_ALIGN to <asm/memory.h>
Currently we define SEGMENT_ALIGN directly in our vmlinux.lds.S.

This is unfortunate, as the EFI stub currently open-codes the same
number, and in future we'll want to fiddle with this.

This patch moves the definition to our <asm/memory.h>, where it can be
used by both vmlinux.lds.S and the EFI stub code.

f60ad4edcf arm64: clean up irq stack definitions
Before we add yet another stack to the kernel, it would be nice to
ensure that we consistently organise stack definitions and related
helper functions.

This patch moves the basic IRQ stack defintions to <asm/memory.h> to
live with their task stack counterparts. Helpers used for unwinding are
moved into <asm/stacktrace.h>, where subsequent patches will add helpers
for other stacks. Includes are fixed up accordingly.

This patch is a pure refactoring -- there should be no functional
changes as a result of this patch.

dbc9344a68 arm64: clean up THREAD_* definitions
Currently we define THREAD_SIZE and THREAD_SIZE_ORDER separately, with
the latter dependent on particular CONFIG_ARM64_*K_PAGES definitions.
This is somewhat opaque, and will get in the way of future modifications
to THREAD_SIZE.

This patch cleans this up, defining both in terms of a common
THREAD_SHIFT, and using PAGE_SHIFT to calculate THREAD_SIZE_ORDER,
rather than using a number of definitions dependent on config symbols.
Subsequent patches will make use of this to alter the stack size used in
some configurations.

At the same time, these are moved into <asm/memory.h>, which will avoid
circular include issues in subsequent patches. To ensure that existing
code isn't adversely affected, <asm/thread_info.h> is updated to
transitively include these definitions.

b6531456ba arm64: factor out PAGE_* and CONT_* definitions
Some headers rely on PAGE_* definitions from <asm/page.h>, but cannot
include this due to potential circular includes. For example, a number
of definitions in <asm/memory.h> rely on PAGE_SHIFT, and <asm/page.h>
includes <asm/memory.h>.

This requires users of these definitions to include both headers, which
is fragile and error-prone.

This patch ameliorates matters by moving the basic definitions out to a
new header, <asm/page-def.h>. Both <asm/page.h> and <asm/memory.h> are
updated to include this, avoiding this fragility, and avoiding the
possibility of circular include dependencies.

82cd588052 arm64: avoid overflow in VA_START and PAGE_OFFSET
The bitmask used to define these values produces overflow, as seen by
this compiler warning:

arch/arm64/kernel/head.S:47:8: warning:
      integer overflow in preprocessor expression
  #elif (PAGE_OFFSET & 0x1fffff) != 0
         ^~~~~~~~~~~
arch/arm64/include/asm/memory.h:52:46: note:
      expanded from macro 'PAGE_OFFSET'
  #define PAGE_OFFSET             (UL(0xffffffffffffffff) << (VA_BITS -
1))
                                      ~~~~~~~~~~~~~~~~~~  ^

It would be preferrable to use GENMASK_ULL() instead, but it's not set
up to be used from assembly (the UL() macro token pastes UL suffixes
when not included in assembly sources).

called 'page', we'll refer to the wrong struct name (which might not
exist).

ec6d06efb0 arm64: Add support for CONFIG_DEBUG_VIRTUAL
x86 has an option CONFIG_DEBUG_VIRTUAL to do additional checks
on virt_to_phys calls. The goal is to catch users who are calling
virt_to_phys on non-linear addresses immediately. This inclues callers
using virt_to_phys on image addresses instead of __pa_symbol. As features
such as CONFIG_VMAP_STACK get enabled for arm64, this becomes increasingly
important. Add checks to catch bad virt_to_phys usage.

__ASSEMBLY__ guard. Move them in preparation for support for
CONFIG_DEBUG_VIRTUAL.

3fa72fe9c6 arm64: mm: fix __page_to_voff definition
Fix parameter name for __page_to_voff, to match its definition.
At present, we don't see any issue, as page_to_virt's caller
declares 'page'.

Fixes: 9f2875912d ("arm64: mm: restrict virt_to_page() to the linear mapping")

ca219452c6 arm64: Correctly bounds check virt_addr_valid
virt_addr_valid is supposed to return true if and only if virt_to_page
returns a valid page structure. The current macro does math on whatever
address is given and passes that to pfn_valid to verify. vmalloc and
module addresses can happen to generate a pfn that 'happens' to be
valid. Fix this by only performing the pfn_valid check on addresses that
have the potential to be valid.

a13e3a5b54 arm64: update stale PAGE_OFFSET comment
Commit ab893fb9f1 ("arm64: introduce KIMAGE_VADDR as the virtual
base of the kernel region") logically split KIMAGE_VADDR from
PAGE_OFFSET, and since commit f9040773b7 ("arm64: move kernel
image to base of vmalloc area") the two have been distinct values.

Unfortunately, neither commit updated the comment above these
definitions, which now erroneously states that PAGE_OFFSET is the start
of the kernel image rather than the start of the linear mapping.

This patch fixes said comment, and introduces an explanation of
KIMAGE_VADDR.

9f2875912d arm64: mm: restrict virt_to_page() to the linear mapping
Now that the vmemmap region has been redefined to cover the linear region
rather than the entire physical address space, we no longer need to
perform a virtual-to-physical translation in the implementaion of
virt_to_page(). This restricts virt_to_page() translations to the linear
region, so redefine virt_addr_valid() as well.
