* m68k: switch to MEMBLOCK + NO_BOOTMEMMike Rapoport2018-07-292-26/+8
| | | | | | | | | | | | | | | | | In m68k the physical memory is described by [memory_start, memory_end] for !MMU variant and by m68k_memory array of memory ranges for the MMU version. This information is directly use to register the physical memory with memblock. The reserve_bootmem() calls are replaced with memblock_reserve() and the bootmap bitmap allocation is simply dropped. Since the MMU variant creates early mappings only for the small part of the memory we force bottom-up allocations in memblock.

| | | | | | | | | | | | | Commit 397ac99c6cef ("m68k: remove dead timer code") removed set_rtc_mmss() because it was unused in 2012. However, this was itself the only user of the mach_set_clock_mmss() callback and the many implementations of that callback, which are equally unused. This removes all of those as well.

| * m68k: Use read_persistent_clock64() consistentlyArnd Bergmann2018-05-221-6/+9
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | We have two ways of getting the current time from a platform at boot or during suspend: either using read_persistent_clock() or the rtc class operation. We never need both, so I'm hiding the read_persistent_clock variant when the generic RTC is enabled. Since read_persistent_clock() and mktime() are deprecated because of the y2038 overflow of time_t, we should use the time64_t based replacements here. Finally, the dependency on CONFIG_ARCH_USES_GETTIMEOFFSET looks completely bogus in this case, so let's remove that. It was added in commit b13b3f51ff7b ("m68k: fix inclusion of arch_gettimeoffset for non-MMU 68k classic CPU types") to deal with arch_gettimeoffset(), which has since been removed from this file and is unrelated to the RTC functions. The rtc accessors are only used by classic machines, while coldfire uses proper RTC drivers, so we can put the old ifdef back around both functions.

| * m68k: Fix off-by-one calendar monthFinn Thain2018-05-221-7/+7
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This fixes a bug in read_persistent_clock() which causes the system clock to lag the Real Time Clock by one month. The problem was noticed on a Mac, but theoretically it must also affect Atari, BVME6000 and Q40. The tm_mon value in the struct rtc_time passed to mach_hwclk() is zero-based, and atari_mste_hwclk(), atari_tt_hwclk(), bvme6000_hwclk(), mac_hwclk() and q40_hwclk() all make this adjustment. Unfortunately, dn_dummy_hwclk(), mvme147_hwclk(), mvme16x_hwclk(), sun3_hwclk() and sun3x_hwclk() fail to decrement tm_mon. Also m68328_hwclk() assumes a one-based tm_mon. Bring these platforms into line and fix read_persistent_clock() so it works correctly on all m68k platforms. The datasheets for the RTC devices found on the affected platforms all confirm that the year is stored as a value in the range 0-99 and the month is stored as a value in the range 1-12. Please refer to the datasheets for MC146818 (Apollo), DS1643 (MVME), ICM7170 (Sun 3) and M48T02 (Sun 3x).

There remains work to do on nds32, arc, unicore32, powerpc, arm, arm64, ia64 and x86 to get the code that generates siginfo into a simpler and more maintainable state. Most of that work involves refactoring the signal handling code and thus careful code review. Also not included is the work to shrink the in kernel version of struct siginfo. That depends on getting the number of places that directly manipulate struct siginfo under control, as it requires the introduction of struct kernel_siginfo for the in kernel things.

In short about a 5 line reduction in code for every time force_sig_info is called, which makes the calling function clearer.

Note: It is not safe to depend on C initializers to initialize struct siginfo on the stack because C is allowed to skip holes when initializing a structure. The initialization of struct siginfo in tracehook_report_syscall_exit was moved from the helper user_single_step_siginfo into tracehook_report_syscall_exit itself, to make it clear that the local variable siginfo gets fully initialized. In a few cases the scope of struct siginfo has been reduced to make it clear that siginfo siginfo is not used on other paths in the function in which it is declared. Instances of using memset to initialize siginfo have been replaced with calls clear_siginfo for clarity. Signed-off-by: "Eric W. Biederman" <ebiederm@xmission.com>

The progress that was made was the definition of FPE_FLTUNK. Which is usable to fix many of the cases where siginfo generation is erroneously generating SI_USER by setting si_code to 0, that has recently been tagged as FPE_FIXME. You already have the change by way of the arm64 tree as that definition was pulled into the arm64 tree to allow fixing the problem there. What remains is the second round of fixing for what I thought was a trivial change to the struct siginfo when put the union in _sigfault where it belongs. Do to historical reasons 32bit m68k only ensures that pointers are 2 byte aligned. So I have added a m68k test case made of BUILD_BUG_ONs to verify I have this fix correct and possibly catch problems, and I have computed the number of bytes of padding needed for the _addr_bnd and _addr_pkey cases and just use an array of characters that size. For pure paranoia I have written the code so if there is an architecture out there that does not perform any alignment of structures it should still work. With the removal of all of the stale arechitectures this cycle future work on cleaning up struct siginfo should be much easier. Almost all of the conflicting si_code definitions have been removed with the removal of (blackfin, tile, and frv). Plus some of the most difficult to test cases have simply been removed from the tree. Which means that with a little luck copy_siginfo_to_user can become a light weight wrapper around copy_to_user in the next cycle" * 'siginfo-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/ebiederm/user-namespace: m68k: Verify the offsets in struct siginfo never change. signal: Correct the offset of si_pkey and si_lower in struct siginfo on m68k

Therefore, system call functions such as sys_xyzzy() or compat_sys_xyzzy() should only be called from userspace via the syscall table, but not from elsewhere in the kernel. At least on 64-bit x86, it will likely be a hard requirement from v4.17 onwards to not call system call functions in the kernel: It is better to use use a different calling convention for system calls there, where struct pt_regs is decoded on-the-fly in a syscall wrapper which then hands processing over to the actual syscall function. This means that only those parameters which are actually needed for a specific syscall are passed on during syscall entry, instead of filling in six CPU registers with random user space content all the time (which may cause serious trouble down the call chain). Those x86-specific patches will be pushed through the x86 tree in the near future. Moreover, rules on how data may be accessed may differ between kernel data and user data. This is another reason why calling sys_xyzzy() is generally a bad idea, and -- at most -- acceptable in arch-specific code. This patchset removes all in-kernel calls to syscall functions in the kernel with the exception of arch/.

* m68k: add missing SOFTIRQENTRY_TEXT linker sectionGreg Ungerer2017-12-043-0/+6
| | | | | | | | | | | | | | | | | | | | | | | | Commit be7635e7287e ("arch, ftrace: for KASAN put hard/soft IRQ entries into separate sections") added a new linker section, SOFTIRQENTRY_TEXT, to the linker scripts for most architectures. It didn't add it to any of the linker scripts for the m68k architecture. This was not really a problem because it is only defined if either of CONFIG_FUNCTION_GRAPH_TRACER or CONFIG_KASAN are enabled - which can never be true for m68k. However commit 229a71860547 ("irq: Make the irqentry text section unconditional") means that SOFTIRQENTRY_TEXT is now always defined. So on m68k we now end up with a separate ELF section for .softirqentry.text instead of it being part of the .text section. On some m68k targets in some configurations this can also cause a fatal link error: LD vmlinux /usr/local/bin/../m68k-uclinux/bin/ld.real: section .softirqentry.text loaded at [0000000010de10c0,0000000010de12dd] overlaps section .rodata loaded at [0000000010de10c0,0000000010e0fd67] To fix add in the missing SOFTIRQENTRY_TEXT section into the m68k linker scripts.

| | | | | | | | | | | | | | | | | | | | The M54[78]x ColdFire parts are not the only members of the ColdFire family that have an MMU. But currently some of the early MMU initialization code is inside the startup code specific to only the ColdFire M54[78]x parts. Move that early ColdFire MMU init code so that it is run for other ColdFire parts running with MMU enabled. Specifically this means that the MMU initialization code will now also be run for the ColdFire M5441x parts when running with MMU enabled. The code move meant that the extern definition for the mmu_context_init() function had to be moved as well. To make it clear that is ColdFire specific I have renamed that with a "cf_" in front of it and put its extern definition in the mcfmmu.h (which is already included by the setup code).

* License cleanup: add SPDX GPL-2.0 license identifier to files with no licenseGreg Kroah-Hartman2017-11-0216-0/+16

By default all files without license information are under the default license of the kernel, which is GPL version 2. Update the files which contain no license information with the 'GPL-2.0' SPDX license identifier. The SPDX identifier is a legally binding shorthand, which can be used instead of the full boiler plate text. This patch is based on work done by Thomas Gleixner and Kate Stewart and Philippe Ombredanne. How this work was done: Patches were generated and checked against linux-4.14-rc6 for a subset of the use cases: - file had no licensing information it it. - file was a */uapi/* one with no licensing information in it, - file was a */uapi/* one with existing licensing information, Further patches will be generated in subsequent months to fix up cases where non-standard license headers were used, and references to license had to be inferred by heuristics based on keywords. The analysis to determine which SPDX License Identifier to be applied to a file was done in a spreadsheet of side by side results from of the output of two independent scanners (ScanCode & Windriver) producing SPDX tag:value files created by Philippe Ombredanne. Philippe prepared the base worksheet, and did an initial spot review of a few 1000 files. The 4.13 kernel was the starting point of the analysis with 60,537 files assessed. Kate Stewart did a file by file comparison of the scanner results in the spreadsheet to determine which SPDX license identifier(s) to be applied to the file. She confirmed any determination that was not immediately clear with lawyers working with the Linux Foundation. Criteria used to select files for SPDX license identifier tagging was: - Files considered eligible had to be source code files. - Make and config files were included as candidates if they contained >5 lines of source - File already had some variant of a license header in it (even if <5 lines). All documentation files were explicitly excluded. The following heuristics were used to determine which SPDX license identifiers to apply. - when both scanners couldn't find any license traces, file was considered to have no license information in it, and the top level COPYING file license applied. For non */uapi/* files that summary was: SPDX license identifier # files ---------------------------------------------------|------- GPL-2.0 11139 and resulted in the first patch in this series. If that file was a */uapi/* path one, it was "GPL-2.0 WITH Linux-syscall-note" otherwise it was "GPL-2.0". Results of that was: SPDX license identifier # files ---------------------------------------------------|------- GPL-2.0 WITH Linux-syscall-note 930 and resulted in the second patch in this series. - if a file had some form of licensing information in it, and was one of the */uapi/* ones, it was denoted with the Linux-syscall-note if any GPL family license was found in the file or had no licensing in it (per prior point). Results summary: SPDX license identifier # files ---------------------------------------------------|------ GPL-2.0 WITH Linux-syscall-note 270 GPL-2.0+ WITH Linux-syscall-note 169 ((GPL-2.0 WITH Linux-syscall-note) OR BSD-2-Clause) 21 ((GPL-2.0 WITH Linux-syscall-note) OR BSD-3-Clause) 17 LGPL-2.1+ WITH Linux-syscall-note 15 GPL-1.0+ WITH Linux-syscall-note 14 ((GPL-2.0+ WITH Linux-syscall-note) OR BSD-3-Clause) 5 LGPL-2.0+ WITH Linux-syscall-note 4 LGPL-2.1 WITH Linux-syscall-note 3 ((GPL-2.0 WITH Linux-syscall-note) OR MIT) 3 ((GPL-2.0 WITH Linux-syscall-note) AND MIT) 1 and that resulted in the third patch in this series. - when the two scanners agreed on the detected license(s), that became the concluded license(s). - when there was disagreement between the two scanners (one detected a license but the other didn't, or they both detected different licenses) a manual inspection of the file occurred. - In most cases a manual inspection of the information in the file resulted in a clear resolution of the license that should apply (and which scanner probably needed to revisit its heuristics). - When it was not immediately clear, the license identifier was confirmed with lawyers working with the Linux Foundation. - If there was any question as to the appropriate license identifier, the file was flagged for further research and to be revisited later in time. In total, over 70 hours of logged manual review was done on the spreadsheet to determine the SPDX license identifiers to apply to the source files by Kate, Philippe, Thomas and, in some cases, confirmation by lawyers working with the Linux Foundation. Kate also obtained a third independent scan of the 4.13 code base from FOSSology, and compared selected files where the other two scanners disagreed against that SPDX file, to see if there was new insights. The Windriver scanner is based on an older version of FOSSology in part, so they are related. Thomas did random spot checks in about 500 files from the spreadsheets for the uapi headers and agreed with SPDX license identifier in the files he inspected. For the non-uapi files Thomas did random spot checks in about 15000 files. In initial set of patches against 4.14-rc6, 3 files were found to have copy/paste license identifier errors, and have been fixed to reflect the correct identifier. Additionally Philippe spent 10 hours this week doing a detailed manual inspection and review of the 12,461 patched files from the initial patch version early this week with: - a full scancode scan run, collecting the matched texts, detected license ids and scores - reviewing anything where there was a license detected (about 500+ files) to ensure that the applied SPDX license was correct - reviewing anything where there was no detection but the patch license was not GPL-2.0 WITH Linux-syscall-note to ensure that the applied SPDX license was correct This produced a worksheet with 20 files needing minor correction. This worksheet was then exported into 3 different .csv files for the different types of files to be modified. These .csv files were then reviewed by Greg. Thomas wrote a script to parse the csv files and add the proper SPDX tag to the file, in the format that the file expected. This script was further refined by Greg based on the output to detect more types of files automatically and to distinguish between header and source .c files (which need different comment types.) Finally Greg ran the script using the .csv files to generate the patches.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | When doing an nmi backtrace of many cores, most of which are idle, the output is a little overwhelming and very uninformative. Suppress messages for cpus that are idling when they are interrupted and just emit one line, "NMI backtrace for N skipped: idling at pc 0xNNN". We do this by grouping all the cpuidle code together into a new .cpuidle.text section, and then checking the address of the interrupted PC to see if it lies within that section. This commit suitably tags x86 and tile idle routines, and only adds in the minimal framework for other architectures.

That is OK for all existing MMU enabled CPU types, but won't handle the case for some ColdFire SoC CPU parts that we want to support that have no FPU hardware. dump_fpu() is expected to be present by the ELF loader, so we must always have it available and exported.
