* cppcheck: (error) Address of local auto-variable assignedBrian Behlendorf2019-12-182-0/+2
| | | | | | | | | | | | Suppress autoVariables warnings in the lua interpreter. The usage here while unconventional in intentional and the same as upstream. [module/lua/ldebug.c:327]: (error) Address of local auto-variable assigned to a function parameter.

* Wrap Linux module macrosMatthew Macy2019-11-011-7/+7
| | | | | | | | | | MODULE_VERSION is already defined on FreeBSD. Wrap all of the used MODULE_* macros for the sake of consistency and portability. Add a user space noop version to reduce the need for _KERNEL ifdefs. Reviewed-by: Brian Behlendorf <[email protected]> Signed-off-by: Matt Macy <[email protected]> Closes #9542

* Fix channel programs on s390xBrian Behlendorf2019-07-281-1/+1
| | | | | | | | | | | | | | When adapting the original sources for s390x the JMP_BUF_CNT was mistakenly halved due to an incorrect assumption of the size of a unsigned long. They are 8 bytes for the s390x architecture. Increase JMP_BUF_CNT accordingly.

* Update build system and packagingBrian Behlendorf2018-05-296-6/+6
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Minimal changes required to integrate the SPL sources in to the ZFS repository build infrastructure and packaging. Build system and packaging: * Renamed SPL_* autoconf m4 macros to ZFS_*. * Removed redundant SPL_* autoconf m4 macros. * Updated the RPM spec files to remove SPL package dependency. * The zfs package obsoletes the spl package, and the zfs-kmod package obsoletes the spl-kmod package. * The zfs-kmod-devel* packages were updated to add compatibility symlinks under /usr/src/spl-x.y.z until all dependent packages can be updated. They will be removed in a future release. * Updated copy-builtin script for in-kernel builds. * Updated DKMS package to include the spl.ko. * Updated stale AUTHORS file to include all contributors. * Updated stale COPYRIGHT and included the SPL as an exception. * Renamed README.markdown to README.md * Renamed OPENSOLARIS.LICENSE to LICENSE. * Renamed DISCLAIMER to NOTICE. Required code changes: * Removed redundant HAVE_SPL macro. * Removed _BOOT from nvpairs since it doesn't apply for Linux. * Initial header cleanup (removal of empty headers, refactoring). * Remove SPL repository clone/build from zimport.sh. * Use of DEFINE_RATELIMIT_STATE and DEFINE_SPINLOCK removed due to build issues when forcing C99 compilation. * Replaced legacy ACCESS_ONCE with READ_ONCE. * Include needed headers for `current` and `EXPORT_SYMBOL`.

* Address objtool check failures in lua moduleDon Brady2018-02-151-1/+3
| | | | | | | | | | | | The use of void __attribute__((noreturn)) in kernel builds was causing lots of warnings if CONFIG_STACK_VALIDATION is active. For now we just remove this attribute to achieve clean builds for the Lua module. There was no significant increase in the time to run the full channel_program ZTS tests.
