7Subject: [PATCH] aarch64: Fix up __aarch64_cas16_acq_rel fallback
8
9As mentioned in the PR, the fallback path when LSE is unavailable writes
10incorrect registers to the memory if the previous content compares equal
11to x0, x1 - it writes copy of x0, x1 from the start of function, but it
12should write x2, x3.

8Subject: [PATCH 1/3] aarch64: New Straight Line Speculation (SLS) mitigation
9 flags
10
11Here we introduce the flags that will be used for straight line speculation.
12
13The new flag introduced is `-mharden-sls=`.
14This flag can take arguments of `none`, `all`, or a comma seperated list of one
15or more of `retbr` or `blr`.
16`none` indicates no special mitigation of the straight line speculation
17vulnerability.
18`all` requests all mitigations currently implemented.
19`retbr` requests that the RET and BR instructions have a speculation barrier
20inserted after them.
21`blr` requests that BLR instructions are replaced by a BL to a function stub
22using a BR with a speculation barrier after it.
23
24Setting this on a per-function basis using attributes or the like is not
25enabled, but may be in the future.

7Subject: [PATCH 2/3] aarch64: Introduce SLS mitigation for RET and BR
8 instructions
9
10Instructions following RET or BR are not necessarily executed. In order
11to avoid speculation past RET and BR we can simply append a speculation
12barrier.
13
14Since these speculation barriers will not be architecturally executed,
15they are not expected to add a high performance penalty.
16
17The speculation barrier is to be SB when targeting architectures which
18have this enabled, and DSB SY + ISB otherwise.
19
20We add tests for each of the cases where such an instruction was seen.
21
22This is implemented by modifying each machine description pattern that
23emits either a RET or a BR instruction. We choose not to use something
24like `TARGET_ASM_FUNCTION_EPILOGUE` since it does not affect the
25`indirect_jump`, `jump`, `sibcall_insn` and `sibcall_value_insn`
26patterns and we find it preferable to implement the functionality in the
27same way for every pattern.
28
29There is one particular case which is slightly tricky. The
30implementation of TARGET_ASM_TRAMPOLINE_TEMPLATE uses a BR which needs
31to be mitigated against. The trampoline template is used *once* per
32compilation unit, and the TRAMPOLINE_SIZE is exposed to the user via the
33builtin macro __LIBGCC_TRAMPOLINE_SIZE__.
34In the future we may implement function specific attributes to turn on
35and off hardening on a per-function basis.
36The fixed nature of the trampoline described above implies it will be
37safer to ensure this speculation barrier is always used.
38
39Testing:
40 Bootstrap and regtest done on aarch64-none-linux
41 Used a temporary hack(1) to use these options on every test in the
42 testsuite and a script to check that the output never emitted an
43 unmitigated RET or BR.
44
451) Temporary hack was a change to the testsuite to always use
46`-save-temps` and run a script on the assembly output of those
47compilations which produced one to ensure every RET or BR is immediately
48followed by a speculation barrier.
49
50gcc/ChangeLog:
51
52 * config/aarch64/aarch64-protos.h (aarch64_sls_barrier): New.

56 of code copied.
57 (aarch64_sls_barrier): New.
58 (aarch64_asm_trampoline_template): Add needed barriers.
59 * config/aarch64/aarch64.h (AARCH64_ISA_SB): New.
60 (TARGET_SB): New.
61 (TRAMPOLINE_SIZE): Account for barrier.
62 * config/aarch64/aarch64.md (indirect_jump, *casesi_dispatch,
63 simple_return, *do_return, *sibcall_insn, *sibcall_value_insn):
64 Emit barrier if needs be, also account for possible barrier using
65 "sls_length" attribute.
66 (sls_length): New attribute.
67 (length): Determine default using any non-default sls_length
68 value.

7Subject: [PATCH 3/3] aarch64: Mitigate SLS for BLR instruction
8
9This patch introduces the mitigation for Straight Line Speculation past
10the BLR instruction.
11
12This mitigation replaces BLR instructions with a BL to a stub which uses
13a BR to jump to the original value. These function stubs are then
14appended with a speculation barrier to ensure no straight line
15speculation happens after these jumps.
16
17When optimising for speed we use a set of stubs for each function since
18this should help the branch predictor make more accurate predictions
19about where a stub should branch.
20
21When optimising for size we use one set of stubs for all functions.
22This set of stubs can have human readable names, and we are using
23`__call_indirect_x<N>` for register x<N>.
24
25When BTI branch protection is enabled the BLR instruction can jump to a
26`BTI c` instruction using any register, while the BR instruction can
27only jump to a `BTI c` instruction using the x16 or x17 registers.
28Hence, in order to ensure this transformation is safe we mov the value
29of the original register into x16 and use x16 for the BR.
30
31As an example when optimising for size:
32a
33 BLR x0
34instruction would get transformed to something like
35 BL __call_indirect_x0
36where __call_indirect_x0 labels a thunk that contains
37__call_indirect_x0:
38 MOV X16, X0
39 BR X16
40 <speculation barrier>
41
42The first version of this patch used local symbols specific to a
43compilation unit to try and avoid relocations.
44This was mistaken since functions coming from the same compilation unit
45can still be in different sections, and the assembler will insert
46relocations at jumps between sections.
47
48On any relocation the linker is permitted to emit a veneer to handle
49jumps between symbols that are very far apart. The registers x16 and
50x17 may be clobbered by these veneers.
51Hence the function stubs cannot rely on the values of x16 and x17 being
52the same as just before the function stub is called.
53
54Similar can be said for the hot/cold partitioning of single functions,
55so function-local stubs have the same restriction.
56
57This updated version of the patch never emits function stubs for x16 and
58x17, and instead forces other registers to be used.
59
60Given the above, there is now no benefit to local symbols (since they
61are not enough to avoid dealing with linker intricacies). This patch
62now uses global symbols with hidden visibility each stored in their own
63COMDAT section. This means stubs can be shared between compilation
64units while still avoiding the PLT indirection.
65
66This patch also removes the `__call_indirect_x30` stub (and
67function-local equivalent) which would simply jump back to the original
68location.
69
70The function-local stubs are emitted to the assembly output file in one
71chunk, which means we need not add the speculation barrier directly
72after each one.
73This is because we know for certain that the instructions directly after
74the BR in all but the last function stub will be from another one of
75these stubs and hence will not contain a speculation gadget.
76Instead we add a speculation barrier at the end of the sequence of
77stubs.
78
79The global stubs are emitted in COMDAT/.linkonce sections by
80themselves so that the linker can remove duplicates from multiple object
81files. This means they are not emitted in one chunk, and each one must
82include the speculation barrier.
83
84Another difference is that since the global stubs are shared across
85compilation units we do not know that all functions will be targeting an
86architecture supporting the SB instruction.
87Rather than provide multiple stubs for each architecture, we provide a
88stub that will work for all architectures -- using the DSB+ISB barrier.
89
90This mitigation does not apply for BLR instructions in the following
91places:
92- Some accesses to thread-local variables use a code sequence with a BLR
93 instruction. This code sequence is part of the binary interface between
94 compiler and linker. If this BLR instruction needs to be mitigated, it'd
95 probably be best to do so in the linker. It seems that the code sequence
96 for thread-local variable access is unlikely to lead to a Spectre Revalation
97 Gadget.
98- PLT stubs are produced by the linker and each contain a BLR instruction.
99 It seems that at most only after the last PLT stub a Spectre Revalation
100 Gadget might appear.
101
102Testing:
103 Bootstrap and regtest on AArch64
104 (with BOOT_CFLAGS="-mharden-sls=retbr,blr")
105 Used a temporary hack(1) in gcc-dg.exp to use these options on every
106 test in the testsuite, a slight modification to emit the speculation
107 barrier after every function stub, and a script to check that the
108 output never emitted a BLR, or unmitigated BR or RET instruction.
109 Similar on an aarch64-none-elf cross-compiler.
110
1111) Temporary hack emitted a speculation barrier at the end of every stub
112function, and used a script to ensure that:
113 a) Every RET or BR is immediately followed by a speculation barrier.
114 b) No BLR instruction is emitted by compiler.
