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.

Adds new 2 new tests to the PTMU script: pmtu_ipv4/6_route_change. These tests explicitly test for a recently discovered problem in the IPv6 routing framework where PMTU exceptions were not properly released when replacing a route via "ip route change ...". After creating PMTU exceptions, the route from the device A to R1 will be replaced with a new route, then device A will be deleted. If the PMTU exceptions were properly cleaned up by the kernel, this device deletion will succeed. Otherwise, the unregistration of the device will stall, and messages such as the following will be logged in dmesg: unregister_netdevice: waiting for veth_A-R1 to become free.

kunit_tool relies on the UML console outputting printk() output to the tty in order to get results. Since the default console driver could change, pass 'console=tty' to the kernel. This is triggered by a change[1] to use ttynull as a fallback console driver which -- by chance or by design -- seems to have changed the default console output on UML, breaking kunit_tool. While this may be fixed, we should be less fragile to such changes in the default.

When CONFIG_BPF_LSM is not set, bpf_lsm will not be compiled, so vmlinux.h will not include definition of BPF_F_BPRM_SECUREEXEC.

Replace usages of perf_cpu_map with cpu_aggr map in places that are involved with 'perf stat' aggregation. This will then later be changed to be a map of cpu_aggr_id rather than an int so that more data can be stored. No functional changes.

Currently this is a duplicate of perf_cpu_map so that it can be used as a drop in replacement. In a later commit it will be changed from a map of ints to use the new cpu_aggr_id struct.
