In order -to avoid speculation past RET and BR we can simply append a speculation -barrier. - -Since these speculation barriers will not be architecturally executed, -they are not expected to add a high performance penalty. - -The speculation barrier is to be SB when targeting architectures which -have this enabled, and DSB SY + ISB otherwise. - -We add tests for each of the cases where such an instruction was seen. - -This is implemented by modifying each machine description pattern that -emits either a RET or a BR instruction. We choose not to use something -like `TARGET_ASM_FUNCTION_EPILOGUE` since it does not affect the -`indirect_jump`, `jump`, `sibcall_insn` and `sibcall_value_insn` -patterns and we find it preferable to implement the functionality in the -same way for every pattern. - -There is one particular case which is slightly tricky. The -implementation of TARGET_ASM_TRAMPOLINE_TEMPLATE uses a BR which needs -to be mitigated against. The trampoline template is used *once* per -compilation unit, and the TRAMPOLINE_SIZE is exposed to the user via the -builtin macro __LIBGCC_TRAMPOLINE_SIZE__. -In the future we may implement function specific attributes to turn on -and off hardening on a per-function basis. -The fixed nature of the trampoline described above implies it will be -safer to ensure this speculation barrier is always used. - -Testing: - Bootstrap and regtest done on aarch64-none-linux - Used a temporary hack(1) to use these options on every test in the - testsuite and a script to check that the output never emitted an - unmitigated RET or BR. - -1) Temporary hack was a change to the testsuite to always use -`-save-temps` and run a script on the assembly output of those -compilations which produced one to ensure every RET or BR is immediately -followed by a speculation barrier. - -gcc/ChangeLog: - - * config/aarch64/aarch64-protos.h (aarch64_sls_barrier): New. - * config/aarch64/aarch64.c (aarch64_output_casesi): Emit - speculation barrier after BR instruction if needs be. - (aarch64_trampoline_init): Handle ptr_mode value & adjust size - of code copied. - (aarch64_sls_barrier): New. - (aarch64_asm_trampoline_template): Add needed barriers. - * config/aarch64/aarch64.h (AARCH64_ISA_SB): New. - (TARGET_SB): New. - (TRAMPOLINE_SIZE): Account for barrier. - * config/aarch64/aarch64.md (indirect_jump, *casesi_dispatch, - simple_return, *do_return, *sibcall_insn, *sibcall_value_insn): - Emit barrier if needs be, also account for possible barrier using - "sls_length" attribute. - (sls_length): New attribute. - (length): Determine default using any non-default sls_length - value. - -gcc/testsuite/ChangeLog: - - * gcc.target/aarch64/sls-mitigation/sls-miti-retbr.c: New test. - * gcc.target/aarch64/sls-mitigation/sls-miti-retbr-pacret.c: - New test. - * gcc.target/aarch64/sls-mitigation/sls-mitigation.exp: New file. - * lib/target-supports.exp (check_effective_target_aarch64_asm_sb_ok): - New proc. ---- - gcc/config/aarch64/aarch64-protos.h | 1 + - gcc/config/aarch64/aarch64.c | 41 ++++++- - gcc/config/aarch64/aarch64.h | 10 +- - gcc/config/aarch64/aarch64.md | 76 +++++++++---- - .../aarch64/sls-mitigation/sls-miti-retbr-pacret.c | 21 ++++ - .../aarch64/sls-mitigation/sls-miti-retbr.c | 119 +++++++++++++++++++++ - .../aarch64/sls-mitigation/sls-mitigation.exp | 73 +++++++++++++ - gcc/testsuite/lib/target-supports.exp | 2 +- - 8 files changed, 318 insertions(+), 25 deletions(-) - create mode 100644 gcc/testsuite/gcc.target/aarch64/sls-mitigation/sls-miti-retbr-pacret.c - create mode 100644 gcc/testsuite/gcc.target/aarch64/sls-mitigation/sls-miti-retbr.c - create mode 100644 gcc/testsuite/gcc.target/aarch64/sls-mitigation/sls-mitigation.exp - -diff --git a/gcc/config/aarch64/aarch64-protos.h b/gcc/config/aarch64/aarch64-protos.h -index eb5f4b4..ee0ffde 100644 ---- a/gcc/config/aarch64/aarch64-protos.h -+++ b/gcc/config/aarch64/aarch64-protos.h -@@ -781,6 +781,7 @@ extern const atomic_ool_names aarch64_ool_ldeor_names; - - tree aarch64_resolve_overloaded_builtin_general (location_t, tree, void *); - -+const char *aarch64_sls_barrier (int); - extern bool aarch64_harden_sls_retbr_p (void); - extern bool aarch64_harden_sls_blr_p (void); - -diff --git a/gcc/config/aarch64/aarch64.c b/gcc/config/aarch64/aarch64.c -index 437a9cf..44e3d1f 100644 ---- a/gcc/config/aarch64/aarch64.c -+++ b/gcc/config/aarch64/aarch64.c -@@ -10852,8 +10852,8 @@ aarch64_return_addr (int count, rtx frame ATTRIBUTE_UNUSED) - static void - aarch64_asm_trampoline_template (FILE *f) - { -- int offset1 = 16; -- int offset2 = 20; -+ int offset1 = 24; -+ int offset2 = 28; - - if (aarch64_bti_enabled ()) - { -@@ -10876,6 +10876,17 @@ aarch64_asm_trampoline_template (FILE *f) - } - asm_fprintf (f, "\tbr\t%s\n", reg_names [IP1_REGNUM]); - -+ /* We always emit a speculation barrier. -+ This is because the same trampoline template is used for every nested -+ function.

-This patch introduces the mitigation for Straight Line Speculation past -the BLR instruction. - -This mitigation replaces BLR instructions with a BL to a stub which uses -a BR to jump to the original value. These function stubs are then -appended with a speculation barrier to ensure no straight line -speculation happens after these jumps. - -When optimising for speed we use a set of stubs for each function since -this should help the branch predictor make more accurate predictions -about where a stub should branch. - -When optimising for size we use one set of stubs for all functions. -This set of stubs can have human readable names, and we are using -`__call_indirect_x<N>` for register x<N>. - -When BTI branch protection is enabled the BLR instruction can jump to a -`BTI c` instruction using any register, while the BR instruction can -only jump to a `BTI c` instruction using the x16 or x17 registers. -Hence, in order to ensure this transformation is safe we mov the value -of the original register into x16 and use x16 for the BR. - -As an example when optimising for size: -a - BLR x0 -instruction would get transformed to something like - BL __call_indirect_x0 -where __call_indirect_x0 labels a thunk that contains -__call_indirect_x0: - MOV X16, X0 - BR X16 - <speculation barrier> - -The first version of this patch used local symbols specific to a -compilation unit to try and avoid relocations. -This was mistaken since functions coming from the same compilation unit -can still be in different sections, and the assembler will insert -relocations at jumps between sections. - -On any relocation the linker is permitted to emit a veneer to handle -jumps between symbols that are very far apart. The registers x16 and -x17 may be clobbered by these veneers. -Hence the function stubs cannot rely on the values of x16 and x17 being -the same as just before the function stub is called. - -Similar can be said for the hot/cold partitioning of single functions, -so function-local stubs have the same restriction. - -This updated version of the patch never emits function stubs for x16 and -x17, and instead forces other registers to be used. - -Given the above, there is now no benefit to local symbols (since they -are not enough to avoid dealing with linker intricacies). This patch -now uses global symbols with hidden visibility each stored in their own -COMDAT section. This means stubs can be shared between compilation -units while still avoiding the PLT indirection. - -This patch also removes the `__call_indirect_x30` stub (and -function-local equivalent) which would simply jump back to the original -location. - -The function-local stubs are emitted to the assembly output file in one -chunk, which means we need not add the speculation barrier directly -after each one. -This is because we know for certain that the instructions directly after -the BR in all but the last function stub will be from another one of -these stubs and hence will not contain a speculation gadget. -Instead we add a speculation barrier at the end of the sequence of -stubs. - -The global stubs are emitted in COMDAT/.linkonce sections by -themselves so that the linker can remove duplicates from multiple object -files. This means they are not emitted in one chunk, and each one must -include the speculation barrier. - -Another difference is that since the global stubs are shared across -compilation units we do not know that all functions will be targeting an -architecture supporting the SB instruction. -Rather than provide multiple stubs for each architecture, we provide a -stub that will work for all architectures -- using the DSB+ISB barrier. - -This mitigation does not apply for BLR instructions in the following -places: -- Some accesses to thread-local variables use a code sequence with a BLR - instruction.

For some reason qemu appears to accept the test +code when it shouldn't. Our selected MIPS cpu for QEMU doesn't support them. + +MIPS is unusual in the gcc testsuite as it uses EFFECTIVE_TARGETS and loops +multiple times through the vector testsuite. In the case of the two above, we can +compile/link them but not run them. Even with the runtime disabled, if the code +marks it as a runtime test, it will elevate itself to that. Setting the default +target to compile therefore isn't enough. + +Therefore add code to downgrade runtime tests to link tests if the hardware +support isn't there to run them.

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.

For simplicity, the code probes all +allocations at offset 1024. + +Some register saves also act as probes.

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.

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. + +gcc/testsuite/ + * gcc.target/aarch64/stack-check-prologue-18.c: New test. + * gcc.target/aarch64/stack-check-prologue-19.c: Likewise. + * gcc.target/aarch64/stack-check-prologue-20.c: Likewise. +--- + gcc/config/aarch64/aarch64.cc | 72 ++++++------- + .../aarch64/stack-check-prologue-18.c | 100 ++++++++++++++++++ + .../aarch64/stack-check-prologue-19.c | 100 ++++++++++++++++++ + .../aarch64/stack-check-prologue-20.c | 3 + + 4 files changed, 233 insertions(+), 42 deletions(-) + create mode 100644 gcc/testsuite/gcc.target/aarch64/stack-check-prologue-18.c + create mode 100644 gcc/testsuite/gcc.target/aarch64/stack-check-prologue-19.c + create mode 100644 gcc/testsuite/gcc.target/aarch64/stack-check-prologue-20.c + +diff --git a/gcc/config/aarch64/aarch64.cc b/gcc/config/aarch64/aarch64.cc +index 5cad847977a..a765f92329d 100644 +--- a/gcc/config/aarch64/aarch64.cc ++++ b/gcc/config/aarch64/aarch64.cc +@@ -8534,26 +8534,34 @@ aarch64_layout_frame (void) + bool saves_below_hard_fp_p + = maybe_ne (frame.below_hard_fp_saved_regs_size, 0); + frame.bytes_below_hard_fp = offset; ++ ++ auto allocate_gpr_slot = [&](unsigned int regno) ++ { ++ frame.reg_offset[regno] = offset; ++ if (frame.wb_push_candidate1 == INVALID_REGNUM) ++ frame.wb_push_candidate1 = regno; ++ else if (frame.wb_push_candidate2 == INVALID_REGNUM) ++ frame.wb_push_candidate2 = regno; ++ offset += UNITS_PER_WORD; ++ }; ++ + if (frame.emit_frame_chain) + { + /* FP and LR are placed in the linkage record. */ +- frame.reg_offset[R29_REGNUM] = offset; +- frame.wb_push_candidate1 = R29_REGNUM; +- frame.reg_offset[R30_REGNUM] = offset + UNITS_PER_WORD; +- frame.wb_push_candidate2 = R30_REGNUM; +- offset += 2 * UNITS_PER_WORD; ++ allocate_gpr_slot (R29_REGNUM); ++ allocate_gpr_slot (R30_REGNUM); + } ++ else if (flag_stack_clash_protection ++ && known_eq (frame.reg_offset[R30_REGNUM], SLOT_REQUIRED)) ++ /* Put the LR save slot first, since it makes a good choice of probe ++ for stack clash purposes.

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. + +gcc/testsuite/ + * gcc.target/aarch64/stack-protector-8.c: New test. + * gcc.target/aarch64/stack-protector-9.c: Likewise. +--- + gcc/config/aarch64/aarch64.cc | 46 +++++++-- + .../gcc.target/aarch64/stack-protector-8.c | 95 +++++++++++++++++++ + .../gcc.target/aarch64/stack-protector-9.c | 33 +++++++ + 3 files changed, 168 insertions(+), 6 deletions(-) + create mode 100644 gcc/testsuite/gcc.target/aarch64/stack-protector-8.c + create mode 100644 gcc/testsuite/gcc.target/aarch64/stack-protector-9.c + +diff --git a/gcc/config/aarch64/aarch64.cc b/gcc/config/aarch64/aarch64.cc +index b95e805a8cc..389c0e29353 100644 +--- a/gcc/config/aarch64/aarch64.cc ++++ b/gcc/config/aarch64/aarch64.cc +@@ -8394,6 +8394,20 @@ aarch64_needs_frame_chain (void) + return aarch64_use_frame_pointer; + } + ++/* Return true if the current function should save registers above ++ the locals area, rather than below it. */ ++ ++static bool ++aarch64_save_regs_above_locals_p () ++{ ++ /* When using stack smash protection, make sure that the canary slot ++ comes between the locals and the saved registers.
