Linus Torvalds 69fc06f70f There are a lot of objtool changes in this cycle, all across the map: ... - Speed up objtool significantly, especially when there are large number of sections - Improve objtool's understanding of special instructions such as IRET, to reduce the number of annotations required - Implement 'noinstr' validation - Do baby steps for non-x86 objtool use - Simplify/fix retpoline decoding - Add vmlinux validation - Improve documentation - Fix various bugs and apply smaller cleanups Signed-off-by: Ingo Molnar <mingo@kernel.org> -----BEGIN PGP SIGNATURE----- iQJFBAABCgAvFiEEBpT5eoXrXCwVQwEKEnMQ0APhK1gFAl7VHvcRHG1pbmdvQGtl cm5lbC5vcmcACgkQEnMQ0APhK1gEfBAAhvPWljUmfQsetYq4q9BdbuC4xPSQN9ra e+2zu1MQaohkjAdFM1boNVhCCGKFUvlTEEw3GJR141Us6Y/ZRS8VIo70tmVSku6I OwuR5i8SgEKwurr1SwLxrI05rovYWRLSaDIRTHn2CViPEjgriyFGRV8QKam3AYmI dx47la3ELwuQR68nIdIMzDRt49oZVy+ZKW8Pjgjklzrd5KMYsPy7HPtraHUMeDg+ GdoC7RresIt5AFiDiIJzKTT/jROI7KuHFnM6blluKHoKenWhYBFCz3sd6IvCdQWX JGy+KKY6H+YDMSpgc4FRP56M3GI0hX14oCd7L72epSLfOuzPr9Tmf6wfyQ8f50Je LGLD47tyltIcQR9H85YdR8UQspkjSW6xcql4ByCPTEqp0UzSGTsVntvsHzwsgz6A Csh3s+DVdv0rk5ZjMCu8STA2oErpehJm7fmugt2oLx+nsCNCBUI25lilw5JGeq5c +cO0IRxRxHPeRvMWvItTjbixVAHOHYlB00ilDbvsm+GnTJgu/5cMqpXdLvfXI2Rr nl360bSS3t3J4w5rX0mXw4x24vjQmVrA69jU+oo8RSHje2X8Y4Q7sFHNjmN0YAI3 Re8aP6HSLQjioJxGz9aISlrxmPOXe0CMp8JE586SREVgmS/olXtidMgi7l12uZ2B cRdtNYcn31U= =dbCU -----END PGP SIGNATURE----- Merge tag 'objtool-core-2020-06-01' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip Pull objtool updates from Ingo Molnar: "There are a lot of objtool changes in this cycle, all across the map: - Speed up objtool significantly, especially when there are large number of sections - Improve objtool's understanding of special instructions such as IRET, to reduce the number of annotations required - Implement 'noinstr' validation - Do baby steps for non-x86 objtool use - Simplify/fix retpoline decoding - Add vmlinux validation - Improve documentation - Fix various bugs and apply smaller cleanups" * tag 'objtool-core-2020-06-01' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip: (54 commits) objtool: Enable compilation of objtool for all architectures objtool: Move struct objtool_file into arch-independent header objtool: Exit successfully when requesting help objtool: Add check_kcov_mode() to the uaccess safelist samples/ftrace: Fix asm function ELF annotations objtool: optimize add_dead_ends for split sections objtool: use gelf_getsymshndx to handle >64k sections objtool: Allow no-op CFI ops in alternatives x86/retpoline: Fix retpoline unwind x86: Change {JMP,CALL}_NOSPEC argument x86: Simplify retpoline declaration x86/speculation: Change FILL_RETURN_BUFFER to work with objtool objtool: Add support for intra-function calls objtool: Move the IRET hack into the arch decoder objtool: Remove INSN_STACK objtool: Make handle_insn_ops() unconditional objtool: Rework allocating stack_ops on decode objtool: UNWIND_HINT_RET_OFFSET should not check registers objtool: is_fentry_call() crashes if call has no destination x86,smap: Fix smap_{save,restore}() alternatives ...		2020-06-01 13:13:00 -07:00
