- kprobes: use struct_size() for variable size kretprobe_instance data structure. - eprobe: Simplify trace_eprobe list iteration. - probe events: Data structure field access support on BTF argument. . Update BTF argument support on the functions in the kernel loadable modules (only loaded modules are supported). . Move generic BTF access function (search function prototype and get function parameters) to a separated file. . Add a function to search a member of data structure in BTF. . Support accessing BTF data structure member from probe args by C-like arrow('->') and dot('.') operators. e.g. 't sched_switch next=next->pid vruntime=next->se.vruntime' . Support accessing BTF data structure member from $retval. e.g. 'f getname_flags%return +0($retval->name):string' . Add string type checking if BTF type info is available. This will reject if user specify ":string" type for non "char pointer" type. . Automatically assume the fprobe event as a function return event if $retval is used. - selftests/ftrace: Add BTF data field access test cases. - Documentation: Update fprobe event example with BTF data field. -----BEGIN PGP SIGNATURE----- iQFPBAABCgA5FiEEh7BulGwFlgAOi5DV2/sHvwUrPxsFAmTycQkbHG1hc2FtaS5o aXJhbWF0c3VAZ21haWwuY29tAAoJENv7B78FKz8bqS8H/jeR1JhOzIXOvTw7XCFm MrSY/SKi8tQfV6lau2UmoYdbYvYjpqL34XLOQPNf2/lrcL2M9aNYXk9fbhlW8enx vkMyKQ0E5anixkF4vsTbEl9DaprxbpsPVACmZ/7VjQk2JuXIdyaNk8hno9LgIcEq udztb0o2HmDFqAXfRi0LvlSTAIwvXZ+usmEvYpaq1g2WwrCe7NHEYl42vMpj+h4H 9l4t5rA9JyPPX4yQUjtKGW5eRVTwDTm/Gn6DRzYfYzkkiBZv27qfovzBOt672LgG hyot+u7XeKvZx3jjnF7+mRWoH/m0dqyhyi/nPhpIE09VhgwclrbGAcDuR1x6sp01 PHY= =hBDN -----END PGP SIGNATURE----- Merge tag 'probes-v6.6' of git://git.kernel.org/pub/scm/linux/kernel/git/trace/linux-trace Pull probes updates from Masami Hiramatsu: - kprobes: use struct_size() for variable size kretprobe_instance data structure. - eprobe: Simplify trace_eprobe list iteration. - probe events: Data structure field access support on BTF argument. - Update BTF argument support on the functions in the kernel loadable modules (only loaded modules are supported). - Move generic BTF access function (search function prototype and get function parameters) to a separated file. - Add a function to search a member of data structure in BTF. - Support accessing BTF data structure member from probe args by C-like arrow('->') and dot('.') operators. e.g. 't sched_switch next=next->pid vruntime=next->se.vruntime' - Support accessing BTF data structure member from $retval. e.g. 'f getname_flags%return +0($retval->name):string' - Add string type checking if BTF type info is available.
