-Subject: [PATCH 00/19] aarch64: Fix -fstack-protector issue
-Date: Tue, 12 Sep 2023 16:25:10 +0100
-
-This series of patches fixes deficiencies in GCC's -fstack-protector
-implementation for AArch64 when using dynamically allocated stack space.
-This is CVE-2023-4039.  See:
-
-https://developer.arm.com/Arm%20Security%20Center/GCC%20Stack%20Protector%20Vulnerability%20AArch64
-https://github.com/metaredteam/external-disclosures/security/advisories/GHSA-x7ch-h5rf-w2mf
-
-for more details.
-
-The fix is to put the saved registers above the locals area when
--fstack-protector is used.
-
-The series also fixes a stack-clash problem that I found while working
-on the CVE.  In unpatched sources, the stack-clash problem would only
-trigger for unrealistic numbers of arguments (8K 64-bit arguments, or an
-equivalent).  But it would be a more significant issue with the new
--fstack-protector frame layout.  It's therefore important that both
-problems are fixed together.
-
-Some reorganisation of the code seemed necessary to fix the problems in a
-cleanish way.  The series is therefore quite long, but only a handful of
-patches should have any effect on code generation.
-
-See the individual patches for a detailed description.
-
-Tested on aarch64-linux-gnu. Pushed to trunk and to all active branches.
-I've also pushed backports to GCC 7+ to vendors/ARM/heads/CVE-2023-4039.

-Subject: [PATCH 01/19] aarch64: Use local frame vars in shrink-wrapping code
-
-aarch64_layout_frame uses a shorthand for referring to
-cfun->machine->frame:
-
-  aarch64_frame &frame = cfun->machine->frame;
-
-This patch does the same for some other heavy users of the structure.
-No functional change intended.
-
-gcc/
-        * config/aarch64/aarch64.cc (aarch64_save_callee_saves): Use
-        a local shorthand for cfun->machine->frame.
-        (aarch64_restore_callee_saves, aarch64_get_separate_components):
-        (aarch64_process_components): Likewise.
-        (aarch64_allocate_and_probe_stack_space): Likewise.
-        (aarch64_expand_prologue, aarch64_expand_epilogue): Likewise.
-        (aarch64_layout_frame): Use existing shorthand for one more case.

-Subject: [PATCH 02/19] aarch64: Avoid a use of callee_offset
-
-When we emit the frame chain, i.e. when we reach Here in this statement
-of aarch64_expand_prologue:
-
-  if (emit_frame_chain)
-    {
-      // Here
-      ...
-    }
-
-the stack is in one of two states:
-
-- We've allocated up to the frame chain, but no more.
-
-- We've allocated the whole frame, and the frame chain is within easy
-  reach of the new SP.
-
-The offset of the frame chain from the current SP is available
-in aarch64_frame as callee_offset.  It is also available as the
-chain_offset local variable, where the latter is calculated from other
-data.  (However, chain_offset is not always equal to callee_offset when
-!emit_frame_chain, so chain_offset isn't redundant.)
-
-In c600df9a4060da3c6121ff4d0b93f179eafd69d1 I switched to using
-chain_offset for the initialisation of the hard frame pointer:
-
-       aarch64_add_offset (Pmode, hard_frame_pointer_rtx,
--                         stack_pointer_rtx, callee_offset,
-+                         stack_pointer_rtx, chain_offset,
-                          tmp1_rtx, tmp0_rtx, frame_pointer_needed);
-
-But the later REG_CFA_ADJUST_CFA handling still used callee_offset.
-
-I think the difference is harmless, but it's more logical for the
-CFA note to be in sync, and it's more convenient for later patches
-if it uses chain_offset.
-
-gcc/
-        * config/aarch64/aarch64.cc (aarch64_expand_prologue): Use
-        chain_offset rather than callee_offset.

-Subject: [PATCH 03/19] aarch64: Explicitly handle frames with no saved
- registers
-
-If a frame has no saved registers, it can be allocated in one go.
-There is no need to treat the areas below and above the saved
-registers as separate.
-
-And if we allocate the frame in one go, it should be allocated
-as the initial_adjust rather than the final_adjust.  This allows the
-frame size to grow to guard_size - guard_used_by_caller before a stack
-probe is needed.  (A frame with no register saves is necessarily a
-leaf frame.)
-
-This is a no-op as thing stand, since a leaf function will have
-no outgoing arguments, and so all the frame will be above where
-the saved registers normally go.
-
-gcc/
-        * config/aarch64/aarch64.cc (aarch64_layout_frame): Explicitly
-        allocate the frame in one go if there are no saved registers.

-
-The frame layout code currently hard-codes the assumption that

-value into a new field of aarch64_frame.
-
-gcc/

-        field.
-        * config/aarch64/aarch64.cc (aarch64_layout_frame): Initialize it,
-        and use it instead of crtl->outgoing_args_size.
-        (aarch64_get_separate_components): Use bytes_below_saved_regs instead
-        of outgoing_args_size.
-        (aarch64_process_components): Likewise.

-Subject: [PATCH 05/19] aarch64: Add bytes_below_hard_fp to frame info
-
-Following on from the previous bytes_below_saved_regs patch, this one
-records the number of bytes that are below the hard frame pointer.
-This eventually replaces below_hard_fp_saved_regs_size.
-
-If a frame pointer is not needed, the epilogue adds final_adjust
-to the stack pointer before restoring registers:
-
-     aarch64_add_sp (tmp1_rtx, tmp0_rtx, final_adjust, true);
-
-Therefore, if the epilogue needs to restore the stack pointer from
-the hard frame pointer, the directly corresponding offset is:
-
-     -bytes_below_hard_fp + final_adjust
-
-i.e. go from the hard frame pointer to the bottom of the frame,
-then add the same amount as if we were using the stack pointer
-from the outset.
-

-Subject: [PATCH 06/19] aarch64: Tweak aarch64_save/restore_callee_saves
-
-aarch64_save_callee_saves and aarch64_restore_callee_saves took
-a parameter called start_offset that gives the offset of the
-bottom of the saved register area from the current stack pointer.
-However, it's more convenient for later patches if we use the
-bottom of the entire frame as the reference point, rather than
-the bottom of the saved registers.
-
-Doing that removes the need for the callee_offset field.
-Other than that, this is not a win on its own.  It only really
-makes sense in combination with the follow-on patches.
-
-gcc/
-        * config/aarch64/aarch64.h (aarch64_frame::callee_offset): Delete.
-        * config/aarch64/aarch64.cc (aarch64_layout_frame): Remove
-        callee_offset handling.
-        (aarch64_save_callee_saves): Replace the start_offset parameter
-        with a bytes_below_sp parameter.
-        (aarch64_restore_callee_saves): Likewise.
-        (aarch64_expand_prologue): Update accordingly.
-        (aarch64_expand_epilogue): Likewise.

-Subject: [PATCH 08/19] aarch64: Rename locals_offset to bytes_above_locals
-MIME-Version: 1.0
-Content-Type: text/plain; charset=UTF-8
-Content-Transfer-Encoding: 8bit
-
-locals_offset was described as:
-
-  /* Offset from the base of the frame (incomming SP) to the
-     top of the locals area.  This value is always a multiple of
-     STACK_BOUNDARY.  */
-
-This is implicitly an “upside down” view of the frame: the incoming
-SP is at offset 0, and anything N bytes below the incoming SP is at
-offset N (rather than -N).
-
-However, reg_offset instead uses a “right way up” view; that is,
-it views offsets in address terms.  Something above X is at a
-positive offset from X and something below X is at a negative
-offset from X.
-
-Also, even on FRAME_GROWS_DOWNWARD targets like AArch64,
-target-independent code views offsets in address terms too:
-locals are allocated at negative offsets to virtual_stack_vars.
-
-It seems confusing to have *_offset fields of the same structure
-using different polarities like this.  This patch tries to avoid
-that by renaming locals_offset to bytes_above_locals.

-Subject: [PATCH 11/19] aarch64: Measure reg_offset from the bottom of the
- frame
-
-reg_offset was measured from the bottom of the saved register area.
-This made perfect sense with the original layout, since the bottom
-of the saved register area was also the hard frame pointer address.
-It became slightly less obvious with SVE, since we save SVE

-Subject: [PATCH 14/19] aarch64: Tweak stack clash boundary condition
-
-The AArch64 ABI says that, when stack clash protection is used,
-there can be a maximum of 1KiB of unprobed space at sp on entry
-to a function.  Therefore, we need to probe when allocating
->= guard_size - 1KiB of data (>= rather than >).  This is what
-GCC does.
-
-If an allocation is exactly guard_size bytes, it is enough to allocate
-those bytes and probe once at offset 1024.  It isn't possible to use a
-single probe at any other offset: higher would conmplicate later code,
-by leaving more unprobed space than usual, while lower would risk
-leaving an entire page unprobed.  For simplicity, the code probes all
-allocations at offset 1024.
-
-Some register saves also act as probes.  If we need to allocate
-more space below the last such register save probe, we need to
-probe the allocation if it is > 1KiB.  Again, this allocation is
-then sometimes (but not always) probed at offset 1024.  This sort of
-allocation is currently only used for outgoing arguments, which are
-rarely this big.
-
-However, the code also probed if this final outgoing-arguments
-allocation was == 1KiB, rather than just > 1KiB.  This isn't
-necessary, since the register save then probes at offset 1024
-as required.  Continuing to probe allocations of exactly 1KiB
-would complicate later patches.
-
-gcc/
-        * config/aarch64/aarch64.cc (aarch64_allocate_and_probe_stack_space):
-        Don't probe final allocations that are exactly 1KiB in size (after
-        unprobed space above the final allocation has been deducted).

-Subject: [PATCH 15/19] aarch64: Put LR save probe in first 16 bytes
-
--fstack-clash-protection uses the save of LR as a probe for the next
-allocation.  The next allocation could be:
-
-* another part of the static frame, e.g. when allocating SVE save slots
-  or outgoing arguments
-
-* an alloca in the same function
-
-* an allocation made by a callee function
-
-However, when -fomit-frame-pointer is used, the LR save slot is placed
-above the other GPR save slots.  It could therefore be up to 80 bytes
-above the base of the GPR save area (which is also the hard fp address).
-
-aarch64_allocate_and_probe_stack_space took this into account when
-deciding how much subsequent space could be allocated without needing
-a probe.  However, it interacted badly with:
-
-      /* If doing a small final adjustment, we always probe at offset 0.
-         This is done to avoid issues when LR is not at position 0 or when
-         the final adjustment is smaller than the probing offset.  */
-      else if (final_adjustment_p && rounded_size == 0)
-        residual_probe_offset = 0;
-
-which forces any allocation that is smaller than the guard page size
-to be probed at offset 0 rather than the usual offset 1024.  It was
-therefore possible to construct cases in which we had:
-
-* a probe using LR at SP + 80 bytes (or some other value >= 16)
-* an allocation of the guard page size - 16 bytes
-* a probe at SP + 0
-
-which allocates guard page size + 64 consecutive unprobed bytes.
-
-This patch requires the LR probe to be in the first 16 bytes of the
-save area when stack clash protection is active.  Doing it
-unconditionally would cause code-quality regressions.
-
-Putting LR before other registers prevents push/pop allocation
-when shadow call stacks are enabled, since LR is restored
-separately from the other callee-saved registers.
-
-The new comment doesn't say that the probe register is required
-to be LR, since a later patch removes that restriction.
-
-gcc/
-        * config/aarch64/aarch64.cc (aarch64_layout_frame): Ensure that
-        the LR save slot is in the first 16 bytes of the register save area.
-        Only form STP/LDP push/pop candidates if both registers are valid.
-        (aarch64_allocate_and_probe_stack_space): Remove workaround for
-        when LR was not in the first 16 bytes.
-

-Subject: [PATCH 16/19] aarch64: Simplify probe of final frame allocation
-
-Previous patches ensured that the final frame allocation only needs
-a probe when the size is strictly greater than 1KiB.  It's therefore
-safe to use the normal 1024 probe offset in all cases.
-
-The main motivation for doing this is to simplify the code and
-remove the number of special cases.
-
-gcc/
-        * config/aarch64/aarch64.cc (aarch64_allocate_and_probe_stack_space):
-        Always probe the residual allocation at offset 1024, asserting
-        that that is in range.
-
-gcc/testsuite/
-        * gcc.target/aarch64/stack-check-prologue-17.c: Expect the probe
-        to be at offset 1024 rather than offset 0.
-        * gcc.target/aarch64/stack-check-prologue-18.c: Likewise.
-        * gcc.target/aarch64/stack-check-prologue-19.c: Likewise.

-Subject: [PATCH 17/19] aarch64: Explicitly record probe registers in frame
- info
-
-The stack frame is currently divided into three areas:
-
-A: the area above the hard frame pointer
-B: the SVE saves below the hard frame pointer
-C: the outgoing arguments
-
-If the stack frame is allocated in one chunk, the allocation needs a
-probe if the frame size is >= guard_size - 1KiB.  In addition, if the
-function is not a leaf function, it must probe an address no more than
-1KiB above the outgoing SP.  We ensured the second condition by
-
-(1) using single-chunk allocations for non-leaf functions only if
-    the link register save slot is within 512 bytes of the bottom
-    of the frame; and
-
-(2) using the link register save as a probe (meaning, for instance,
-    that it can't be individually shrink wrapped)
-
-If instead the stack is allocated in multiple chunks, then:
-
-* an allocation involving only the outgoing arguments (C above) requires
-  a probe if the allocation size is > 1KiB
-
-* any other allocation requires a probe if the allocation size
-  is >= guard_size - 1KiB
-
-* second and subsequent allocations require the previous allocation
-  to probe at the bottom of the allocated area, regardless of the size
-  of that previous allocation
-
-The final point means that, unlike for single allocations,
-it can be necessary to have both a non-SVE register probe and
-an SVE register probe.  For example:
-
-* allocate A, probe using a non-SVE register save
-* allocate B, probe using an SVE register save
-* allocate C
-
-The non-SVE register used in this case was again the link register.
-It was previously used even if the link register save slot was some
-bytes above the bottom of the non-SVE register saves, but an earlier
-patch avoided that by putting the link register save slot first.
-
-As a belt-and-braces fix, this patch explicitly records which
-probe registers we're using and allows the non-SVE probe to be
-whichever register comes first (as for SVE).
-
-The patch also avoids unnecessary probes in sve/pcs/stack_clash_3.c.
-
-gcc/
-        * config/aarch64/aarch64.h (aarch64_frame::sve_save_and_probe)
-        (aarch64_frame::hard_fp_save_and_probe): New fields.
-        * config/aarch64/aarch64.cc (aarch64_layout_frame): Initialize them.
-        Rather than asserting that a leaf function saves LR, instead assert
-        that a leaf function saves something.
-        (aarch64_get_separate_components): Prevent the chosen probe
-        registers from being individually shrink-wrapped.
-        (aarch64_allocate_and_probe_stack_space): Remove workaround for
-        probe registers that aren't at the bottom of the previous allocation.
-
-gcc/testsuite/
-        * gcc.target/aarch64/sve/pcs/stack_clash_3.c: Avoid redundant probes.

-Subject: [PATCH 19/19] aarch64: Make stack smash canary protect saved
- registers
-
-AArch64 normally puts the saved registers near the bottom of the frame,
-immediately above any dynamic allocations.  But this means that a
-stack-smash attack on those dynamic allocations could overwrite the
-saved registers without needing to reach as far as the stack smash
-canary.
-
-The same thing could also happen for variable-sized arguments that are
-passed by value, since those are allocated before a call and popped on
-return.
-
-This patch avoids that by putting the locals (and thus the canary) below
-the saved registers when stack smash protection is active.
-
-The patch fixes CVE-2023-4039.
-
-gcc/
-        * config/aarch64/aarch64.cc (aarch64_save_regs_above_locals_p):
-        New function.
-        (aarch64_layout_frame): Use it to decide whether locals should
-        go above or below the saved registers.
-        (aarch64_expand_prologue): Update stack layout comment.
-        Emit a stack tie after the final adjustment.
