2022-08-11riscv/purgatory: Omit use of bin2cMasahiro Yamada1-0/+2
The .incbin assembler directive is much faster than bin2c + $(CC). Do similar refactoring as in commit 4c0f032d4963 ("s390/purgatory: Omit use of bin2c"). Please note the .quad directive matches to size_t in C (both 8 byte) because the purgatory is compiled only for the 64-bit kernel. (KEXEC_FILE depends on 64BIT).

2022-08-11Revert "Makefile.extrawarn: re-enable -Wformat for clang"Linus Torvalds1-0/+1
This reverts commit 258fafcd0683d9ccfa524129d489948ab3ddc24c. The clang -Wformat warning is terminally broken, and the clang people can't seem to get their act together. This test program causes a warning with clang: #include <stdio.h> int main(int argc, char **argv) { printf("%hhu\n", 'a'); } resulting in t.c:5:19: warning: format specifies type 'unsigned char' but the argument has type 'int' [-Wformat] printf("%hhu\n", 'a'); ~~~~ ^~~ %d and apparently clang people consider that a feature, because they don't want to face the reality of how either C character constants, C arithmetic, and C varargs functions work. The rest of the world just shakes their head at that kind of incompetence, and turns off -Wformat for clang again. And no, the "you should use a pointless cast to shut this up" is not a valid answer. That warning should not exist in the first place, or at least be optinal with some "-Wformat-me-harder" kind of option. [ Admittedly, there's also very little reason to *ever* use '%hh[ud]' in C, but what little reason there is is entirely about 'I want to see only the low 8 bits of the argument'. So I would suggest nobody ever use that format in the first place, but if they do, the clang behavious is simply always wrong. Because '%hhu' takes an 'int'. It's that simple. ] Reported-by: Sudip Mukherjee (Codethink) <sudipm.mukherjee@gmail.com> Cc: Nick Desaulniers <ndesaulniers@google.com> Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>

2022-08-08Merge tag 'modules-6.0-rc1' of ↵Linus Torvalds1-0/+2
git://git.kernel.org/pub/scm/linux/kernel/git/mcgrof/linux Pull module updates from Luis Chamberlain: "For the 6.0 merge window the modules code shifts to cleanup and minor fixes effort. This becomes much easier to do and review now due to the code split to its own directory from effort on the last kernel release. I expect to see more of this with time and as we expand on test coverage in the future. The cleanups and fixes come from usual suspects such as Christophe Leroy and Aaron Tomlin but there are also some other contributors. One particular minor fix worth mentioning is from Helge Deller, where he spotted a *forever* incorrect natural alignment on both ELF section header tables: * .altinstructions * __bug_table sections A lot of back and forth went on in trying to determine the ill effects of this misalignment being present for years and it has been determined there should be no real ill effects unless you have a buggy exception handler. Helge actually hit one of these buggy exception handlers on parisc which is how he ended up spotting this issue. When implemented correctly these paths with incorrect misalignment would just mean a performance penalty, but given that we are dealing with alternatives on modules and with the __bug_table (where info regardign BUG()/WARN() file/line information associated with it is stored) this really shouldn't be a big deal. The only other change with mentioning is the kmap() with kmap_local_page() and my only concern with that was on what is done after preemption, but the virtual addresses are restored after preemption. This is only used on module decompression. This all has sit on linux-next for a while except the kmap stuff which has been there for 3 weeks" * tag 'modules-6.0-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/mcgrof/linux: module: Replace kmap() with kmap_local_page() module: Show the last unloaded module's taint flag(s) module: Use strscpy() for last_unloaded_module module: Modify module_flags() to accept show_state argument module: Move module's Kconfig items in kernel/module/ MAINTAINERS: Update file list for module maintainers module: Use vzalloc() instead of vmalloc()/memset(0) modules: Ensure natural alignment for .altinstructions and __bug_table sections module: Increase readability of module_kallsyms_lookup_name() module: Fix ERRORs reported by checkpatch.pl module: Add support for default value for module async_probe

It introduces the runtime verification that is necessary for running Linux on safety critical systems. It allows for deterministic automata models to be inserted into the kernel that will attach to tracepoints, where the information on these tracepoints will move the model from state to state. If a state is encountered that does not belong to the model, it will then activate a given reactor, that could just inform the user or even panic the kernel (for which safety critical systems will detect and can recover from). - Two monitor models are also added: Wakeup In Preemptive (WIP - not to be confused with "work in progress"), and Wakeup While Not Running (WWNR). - Added __vstring() helper to the TRACE_EVENT() macro to replace several vsnprintf() usages that were all doing it wrong. - eprobes now can have their event autogenerated when the event name is left off. - The rest is various cleanups and fixes. * tag 'trace-v6.0' of git://git.kernel.org/pub/scm/linux/kernel/git/rostedt/linux-trace: (50 commits) rv: Unlock on error path in rv_unregister_reactor() tracing: Use alignof__(struct {type b;}) instead of offsetof() tracing/eprobe: Show syntax error logs in error_log file scripts/tracing: Fix typo 'the the' in comment tracepoints: It is CONFIG_TRACEPOINTS not CONFIG_TRACEPOINT tracing: Use free_trace_buffer() in allocate_trace_buffers() tracing: Use a struct alignof to determine trace event field alignment rv/reactor: Add the panic reactor rv/reactor: Add the printk reactor rv/monitor: Add the wwnr monitor rv/monitor: Add the wip monitor rv/monitor: Add the wip monitor skeleton created by dot2k Documentation/rv: Add deterministic automata instrumentation documentation Documentation/rv: Add deterministic automata monitor synthesis documentation tools/rv: Add dot2k Documentation/rv: Add deterministic automaton documentation tools/rv: Add dot2c Documentation/rv: Add a basic documentation rv/include: Add instrumentation helper functions rv/include: Add deterministic automata monitor definition via C macros ...

2022-08-03sign-file: Fix confusing error messagesTianjia Zhang1-1/+1
When an error occurs, use errx() instead of err() to display the error message, because openssl has its own error record. When an error occurs, errno will not be changed, while err() displays the errno error message. It will cause confusion. For example, when CMS_add1_signer() fails, the following message will appear: sign-file: CMS_add1_signer: Success errx() ignores errno and does not cause such issue.

2022-08-03modpost: use more reliable way to get fromsec in section_rel(a)()Masahiro Yamada1-4/+2
The section name of Rel and Rela starts with ".rel" and ".rela" respectively (but, I do not know whether this is specification or convention). For example, ".rela.text" holds relocation entries applied to the ".text" section. So, the code chops the ".rel" or ".rela" prefix to get the name of the section to which the relocation applies. However, I do not like to skip 4 or 5 bytes blindly because it is potential memory overrun. The ELF specification provides a more reliable way to do this. - The sh_info field holds extra information, whose interpretation depends on the section type - If the section type is SHT_REL or SHT_RELA, the sh_info field holds the section header index of the section to which the relocation applies.

2022-08-03modpost: add array range check to sec_name()Masahiro Yamada1-1/+9
The section index is always positive, so the argument, secindex, should be unsigned. Also, inserted the array range check. If sym->st_shndx is a special section index (between SHN_LORESERVE and SHN_HIRESERVE), there is no corresponding section header. For example, if a symbol specifies an absolute value, sym->st_shndx is SHN_ABS (=0xfff1). The current users do not cause the out-of-range access of info->sechddrs[], but it is better to avoid such a pitfall. Signed-off-by: Masahiro Yamada <masahiroy@kernel.org>

Swap the order of 'mkdir' and 'trap' just in case the subshell is interrupted between 'mkdir' and 'trap' although the effect might be subtle. This does not intend to make the cleanup perfect. There are more cases that miss to remove the tmp directory, for example: - When interrupted, dash does not invoke the EXIT trap (bash does) - 'rm' command might be interrupted before removing the directory I am not addressing all the cases since the tmp directory is harmless after all.

2022-08-03Makefile.extrawarn: re-enable -Wformat for clangJustin Stitt1-1/+0
There's been an ongoing mission to re-enable the -Wformat warning for Clang. A previous attempt at enabling the warning showed that there were many instances of this warning throughout the codebase. The sheer amount of these warnings really polluted builds and thus -Wno-format was added to _temporarily_ toggle them off. After many patches the warning has largely been eradicated for x86, x86_64, arm, and arm64 on a variety of configs. The time to enable the warning has never been better as it seems for the first time we are ahead of them and can now solve them as they appear rather than tackling from a backlog. As to the root cause of this large backlog of warnings, Clang seems to pickup on some more nuanced cases of format warnings caused by implicit integer conversion as well as default argument promotions from printf-like functions.

In Makefile, '$$$$' is correct (see TMPOUT in scripts/Malefile.compiler) because '$$' is an escape sequence of '$'. Make expands '$$$$' into '$$', then shell expands it into the process ID.
