The OBJECT_FILES_NON_STANDARD annotation is used to tell objtool to ignore a file. File-level ignores won't work when validating vmlinux.o. Instead, convert restore_image() and core_restore_code() to be ELF functions. Their code is conventional enough for objtool to be able to understand them. Cc: "Rafael J.

Because restore_registers() is page-aligned, the assembler inexplicably adds an unreachable jump from after the end of the previous function to the beginning of restore_registers(). That confuses objtool, understandably. It also creates significant text fragmentation. As a result, most of the object file is wasted text (nops). Move restore_registers() to the beginning of the file to both prevent the text fragmentation and avoid the dead jump instruction. $ size /tmp/hibernate_asm_64.before.o /tmp/hibernate_asm_64.after.o text data bss dec hex filename 4415 0 0 4415 113f /tmp/hibernate_asm_64.before.o 524 0 0 524 20c /tmp/hibernate_asm_64.after.o Cc: "Rafael J.

With objtool vmlinux.o validation of return_to_handler(), now that objtool has visibility inside the retpoline, jumping from EMPTY state to a proper function state results in a stack state mismatch. return_to_handler() is actually quite normal despite the underlying magic. Just annotate it as a normal function. Acked-by:

The Xen hypercall page is filled with zeros, causing objtool to fall through all the empty hypercall functions until it reaches a real function, resulting in a stack state mismatch. The build-time contents of the hypercall page don't matter because the page gets rewritten by the hypervisor. Make it more palatable to objtool by making each hypervisor function a true empty function, with nops and a return. Cc: Juergen Gross <jgross@suse.com> Reviewed-by:

The ORC metadata generated for UNWIND_HINT_FUNC isn't actually very func-like. With certain usages it can cause stack state mismatches because it doesn't set the return address (CFI_RA). Also, users of UNWIND_HINT_RET_OFFSET no longer need to set a custom return stack offset. Instead they just need to specify a func-like situation, so the current ret_offset code is hacky for no good reason. Solve both problems by simplifying the RET_OFFSET handling and converting it into a more useful UNWIND_HINT_FUNC. If we end up needing the old 'ret_offset' functionality again in the future, we should be able to support it pretty easily with the addition of a custom 'sp_offset' in UNWIND_HINT_FUNC.

There's an inconsistency in how sibling calls are detected in non-function asm code, depending on the scope of the object. If the target code is external to the object, objtool considers it a sibling call. If the target code is internal but not a function, objtool *doesn't* consider it a sibling call. This can cause some inconsistencies between per-object and vmlinux.o validation. Instead, assume only ELF functions can do sibling calls. This generally matches existing reality, and makes sibling call validation consistent between vmlinux.o and per-object. Signed-off-by:

Objtool converts direct retpoline jumps to type INSN_JUMP_DYNAMIC, since that's what they are semantically. That conversion doesn't work in vmlinux.o validation because the indirect thunk function is present in the object, so the intra-object jump check succeeds before the retpoline jump check gets a chance. Rearrange the checks: check for a retpoline jump before checking for an intra-object jump. Signed-off-by:

With my version of GCC 9.3.1 the ".cold" subfunctions no longer have a numbered suffix, so the trailing period is no longer there. Presumably this doesn't yet trigger a user-visible bug since most of the subfunction detection logic is duplicated. I only found it when testing vmlinux.o validation.

The ORC unwinder showed a warning [1] which revealed the stack layout didn't match what was expected. The problem was that paravirt patching had replaced "CALL *pv_ops.irq.save_fl" with "PUSHF;POP". That changed the stack layout between the PUSHF and the POP, so unwinding from an interrupt which occurred between those two instructions would fail. Part of the agreed upon solution was to rework the custom paravirt patching code to use alternatives instead, since objtool already knows how to read alternatives (and converging runtime patching infrastructure is always a good thing anyway). But the main problem still remains, which is that runtime patching can change the stack layout. Making stack layout changes in alternatives was disallowed with commit 7117f16b ("objtool: Fix ORC vs alternatives"), but now that paravirt is going to be doing it, it needs to be supported. One way to do so would be to modify the ORC table when the code gets patched. But ORC is simple -- a good thing! -- and it's best to leave it alone. Instead, support stack layout changes by "flattening" all possible stack states (CFI) from parallel alternative code streams into a single set of linear states. The only necessary limitation is that CFI conflicts are disallowed at all possible instruction boundaries. For example, this scenario is allowed: Alt1 Alt2 Alt3 0x00 CALL *pv_ops.save_fl CALL xen_save_fl PUSHF 0x01 POP %RAX 0x02 NOP ... 0x05 NOP ... 0x07 <insn> The unwind information for offset-0x00 is identical for all 3 alternatives. Similarly offset-0x05 and higher also are identical (and the same as 0x00). However offset-0x01 has deviating CFI, but that is only relevant for Alt3, neither of the other alternative instruction streams will ever hit that offset. This scenario is NOT allowed: Alt1 Alt2 0x00 CALL *pv_ops.save_fl PUSHF 0x01 NOP6 ... 0x07 NOP POP %RAX The problem here is that offset-0x7, which is an instruction boundary in both possible instruction patch streams, has two conflicting stack layouts. [ The above examples were stolen from Peter Zijlstra. ] The new flattened CFI array is used both for the detection of conflicts (like the second example above) and the generation of linear ORC entries. BTW, another benefit of these changes is that, thanks to some related cleanups (new fake nops and alt_group struct) objtool can finally be rid of fake jumps, which were a constant source of headaches.

Currently objtool headers are being included either by their base name or included via ../ from a parent directory. In case of a base name usage: #include "warn.h" #include "arch_elf.h" it does not make it apparent from which directory the file comes from. To make it slightly better, and actually to avoid name clashes some arch specific files have "arch_" suffix. And files from an arch folder have to revert to including via ../ e.g: #include "../../elf.h" With additional architectures support and the code base growth there is a need for clearer headers naming scheme for multiple reasons: 1. to make it instantly obvious where these files come from (objtool itself / objtool arch|generic folders / some other external files), 2. to avoid name clashes of objtool arch specific headers, potential obtool arch generic headers and the system header files (there is /usr/include/elf.h already), 3. to avoid ../ includes and improve code readability. 4. to give a warm fuzzy feeling to developers who are mostly kernel developers and are accustomed to linux kernel headers arranging scheme. Doesn't this make it instantly obvious where are these files come from? #include <objtool/warn.h> #include <arch/elf.h> And doesn't it look nicer to avoid ugly ../ includes? Which also guarantees this is elf.h from the objtool and not /usr/include/elf.h. #include <objtool/elf.h> This patch defines and implements new objtool headers arranging scheme. Which is: - all generic headers go to include/objtool (similar to include/linux) - all arch headers go to arch/$(SRCARCH)/include/arch (to get arch prefix). This is similar to linux arch specific "asm/*" headers but we are not abusing "asm" name and calling it what it is. This also helps to prevent name clashes (arch is not used in system headers or kernel exports). To bring objtool to this state the following things are done: 1. current top level tools/objtool/ headers are moved into include/objtool/ subdirectory, 2. arch specific headers, currently only arch/x86/include/ are moved into arch/x86/include/arch/ and were stripped of "arch_" suffix, 3. new -I$(srctree)/tools/objtool/include include path to make includes like <objtool/warn.h> possible, 4. rewriting file includes, 5. make git not to ignore include/objtool/ subdirectory.

Correct objtool orc generation endianness problems to enable fully functional x86 cross-compiles on big endian hardware. Introduce bswap_if_needed() macro, which does a byte swap if target endianness doesn't match the host, i.e. cross-compilation for little endian on big endian and vice versa. The macro is used for conversion of multi-byte values which are read from / about to be written to a target native endianness ELF file. Signed-off-by:

Currently the x86 instruction decoder is used from: - the kernel itself, - from tools like objtool and perf, - within x86 tools, i.e. instruction decoder selftests. The first two cases are similar, because tools headers try to mimic kernel headers. Instruction decoder selftests include some of the kernel headers directly, including uapi headers. This works until headers dependencies are kept to a minimum and tools are not cross-compiled. Since the goal of the x86 instruction decoder selftests is not to verify uapi headers, move it to using tools headers, like is already done for vdso2c tool, mkpiggy and other tools in arch/x86/boot/.

A valid stack frame should contain both the return address and the previous frame pointer value. On x86, the return value is placed on the stack by the calling instructions. On other architectures, the callee needs to explicitly save the return address on the stack. Add the necessary checks to verify a function properly sets up all the elements of the stack frame.
