* Add FreeBSD support to OpenZFSMatthew Macy2020-04-141-2/+3
| | | | | | | | | | | | | | | | | | Add the FreeBSD platform code to the OpenZFS repository. As of this commit the source can be compiled and tested on FreeBSD 11 and 12. Subsequent commits are now required to compile on FreeBSD and Linux. Additionally, they must pass the ZFS Test Suite on FreeBSD which is being run by the CI. As of this commit 1230 tests pass on FreeBSD and there are no unexpected failures.

* Perform KABI checks in parallelBrian Behlendorf2019-10-011-3/+3
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Reduce the time required for ./configure to perform the needed KABI checks by allowing kbuild to compile multiple test cases in parallel. This was accomplished by splitting each test's source code from the logic handling whether that code could be compiled or not. By introducing this split it's possible to minimize the number of times kbuild needs to be invoked. As importantly, it means all of the tests can be built in parallel. This does require a little extra care since we expect some tests to fail, so the --keep-going (-k) option must be provided otherwise some tests may not get compiled. Furthermore, since a failure during the kbuild modpost phase will result in an early exit; the final linking phase is limited to tests which passed the initial compilation and produced an object file. Once everything has been built the configure script proceeds as previously. The only significant difference is that it now merely needs to test for the existence of a .ko file to determine the result of a given test. This vastly speeds up the entire process. New test cases should use ZFS_LINUX_TEST_SRC to declare their test source code and ZFS_LINUX_TEST_RESULT to check the result. All of the existing kernel-*.m4 files have been updated accordingly, see config/kernel-current-time.m4 for a basic example. The legacy ZFS_LINUX_TRY_COMPILE macro has been kept to handle special cases but it's use is not encouraged. master (secs) patched (secs) ------------- ---------------- autogen.sh 61 68 configure 137 24 (~17% of current run time) make -j $(nproc) 44 44 make rpms 287 150 Reviewed-by: Tony Hutter <[email protected]> Signed-off-by: Brian Behlendorf <[email protected]> Closes #8547 Closes #9132 Closes #9341

| | | | | | | | | | | | | | | | Since the merge of the Linux Solaris Porting Layer source tree into the ZFS codebase, ZFS is now a double-licensed codebase, with the former SPL codebase retaining its license (GPLv2+) within the ZFS source tree.

* Create /proc/sys/kernel/spl/gitrev with git hashMatthew Ahrens2018-10-081-1/+8
| | | | | | | | | | | | | | | | | | | | | | | | | | | | The existing mechanisms for determining what code is running in the kernel do not always correctly report the git hash. The versions reported there do not reflect changes made since `configure` was run (i.e. incremental builds do not update the version) and they are misleading if git tags are not set up properly. This applies to `modinfo zfs`, `dmesg`, and `/sys/module/zfs/version`. There are complicated requirements on how the existing version is generated. Therefore we are leaving that alone, and adding a new mechanism to record and retrieve the git hash: `cat /proc/sys/kernel/spl/gitrev` The gitrev is re-generated at compile time, when running `make` (including for incremental builds). The value is the output of `git describe` (or "unknown" if not in a git repo or there are uncommitted changes). We're also removing /proc/sys/kernel/spl/version, which was never very useful.

| | | | | | | | | | | | | | | | | We'd like to have tooling that verifies code style, while ignoring the commit message. For example, code does not need to be signed off in order to be tested. Current workarounds are to run `git checkstyle` and ignore the commit message errors, or to run `make cstyle shellcheck flake8 mancheck testscheck`, and make sure that list stays updated. Solution is to add a new make target, `codecheck` which does all the code checks. `checkstyle` is now simply `codecheck` + `commitcheck`.

* Prebaked scripts for zpool status/iostat -cTony Hutter2017-04-211-1/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch updates the "zpool status/iostat -c" commands to only run "pre-baked" scripts from the /etc/zfs/zpool.d directory (or wherever you install to). The scripts can only be run from -c as an unprivileged user (unless the ZPOOL_SCRIPTS_AS_ROOT environment var is set by root). This was done to encourage scripts to be written is such a way that normal users can use them, and to be cautious. If your script needs to run a privileged command, consider adding the appropriate line in /etc/sudoers. See zpool(8) for an example of how to do this. The patch also allows the scripts to output custom column names. If the script outputs a line like: name=value then "name" is used for the column name, and "value" is its value. Multiple columns can be specified by outputting multiple lines. Column names and values can have spaces. If the value is empty, a dash (-) is printed instead. After all the "name=value" lines are read (if any), zpool will take the next the next line of output (if any) and print it without a column header. After that, no more lines will be processed. This can be useful for printing errors. Lastly, this patch also disables the -c option with the latency and request size histograms, since it produced awkward output and made the code harder to maintain.

* Fix make lint targetBrian Behlendorf2016-09-091-1/+1
| | | | | | | | When errors are detected 'make lint' should return a non-zero error code. The value 2 was chosen to indicate these are warnings and not fatal. Signed-off-by: Brian Behlendorf <[email protected]>
* Add `make lint` targetBrian Behlendorf2016-08-021-0/+7
| | | | | | | | | | Add a `make lint` target which maps to a cppcheck target. As with the shellcheck target it will only run when cppcheck is installed. This allows a `make lint` build check to be incrementally added to the automated testing for distribution which provide cppcheck. Signed-off-by: Brian Behlendorf <[email protected]> Closes #4915
* Add the ZFS Test SuiteBrian Behlendorf2016-03-161-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Add the ZFS Test Suite and test-runner framework from illumos. This is a continuation of the work done by Turbo Fredriksson to port the ZFS Test Suite to Linux. While this work was originally conceived as a stand alone project integrating it directly with the ZoL source tree has several advantages: * Allows the ZFS Test Suite to be packaged in zfs-test package. * Facilitates easy integration with the CI testing. * Users can locally run the ZFS Test Suite to validate ZFS. This testing should ONLY be done on a dedicated test system because the ZFS Test Suite in its current form is destructive. * Allows the ZFS Test Suite to be run directly in the ZoL source tree enabled developers to iterate quickly during development. * Developers can easily add/modify tests in the framework as features are added or functionality is changed. The tests will then always be in sync with the implementation. Full documentation for how to run the ZFS Test Suite is available in the tests/README.md file. Warning: This test suite is designed to be run on a dedicated test system. It will make modifications to the system including, but not limited to, the following. * Adding new users * Adding new groups * Modifying the following /proc files: * /proc/sys/kernel/core_pattern * /proc/sys/kernel/core_uses_pid * Creating directories under / Notes: * Not all of the test cases are expected to pass and by default these test cases are disabled. The failures are primarily due to assumption made for illumos which are invalid under Linux. * When updating these test cases it should be done in as generic a way as possible so the patch can be submitted back upstream. Most existing library functions have been updated to be Linux aware, and the following functions and variables have been added. * Functions: * is_linux - Used to wrap a Linux specific section. * block_device_wait - Waits for block devices to be added to /dev/. * Variables: Linux Illumos * ZVOL_DEVDIR "/dev/zvol" "/dev/zvol/dsk" * ZVOL_RDEVDIR "/dev/zvol" "/dev/zvol/rdsk" * DEV_DSKDIR "/dev" "/dev/dsk" * DEV_RDSKDIR "/dev" "/dev/rdsk" * NEWFS_DEFAULT_FS "ext2" "ufs" * Many of the disabled test cases fail because 'zfs/zpool destroy' returns EBUSY. This is largely causes by the asynchronous nature of device handling on Linux and is expected, the impacted test cases will need to be updated to handle this. * There are several test cases which have been disabled because they can trigger a deadlock. A primary example of this is to recursively create zpools within zpools. These tests have been disabled until the root issue can be addressed. * Illumos specific utilities such as (mkfile) should be added to the tests/zfs-tests/cmd/ directory. Custom programs required by the test scripts can also be added here. * SELinux should be either is permissive mode or disabled when running the tests. The test cases should be updated to conform to a standard policy. * Redundant test functionality has been removed (zfault.sh). * Existing test scripts (zconfig.sh) should be migrated to use the framework for consistency and ease of testing. * The DISKS environment variable currently only supports loopback devices because of how the ZFS Test Suite expects partitions to be named (p1, p2, etc). Support must be added to generate the correct partition name based on the device location and name. * The ZFS Test Suite is part of the illumos code base at: https://github.com/illumos/illumos-gate/tree/master/usr/src/test Original-patch-by: Turbo Fredriksson <[email protected]> Signed-off-by: Brian Behlendorf <[email protected]> Signed-off-by: Olaf Faaland <[email protected]> Closes #6 Closes #1534
* Support parallel build trees (VPATH builds)Turbo Fredriksson2015-07-171-6/+5
| | | | | | | | | | | | | | | | | | | | | | | | | | | | Build products from an out of tree build should be written relative to the build directory. Sources should be referred to by their locations in the source directory. This is accomplished by adding the 'src' and 'obj' variables for the module Makefile.am, using relative paths to reference source files, and by setting VPATH when source files are not co-located with the Makefile. This enables the following: $ mkdir build $ cd build $ ../configure \ --with-spl=$HOME/src/git/spl/ \ --with-spl-obj=$HOME/src/git/spl/build $ make -s This change also has the advantage of resolving the following warning which is generated by modern versions of automake. Makefile.am:00: warning: source file 'xxx' is in a subdirectory, Makefile.am:00: but option 'subdir-objects' is disabled Signed-off-by: Turbo Fredriksson <[email protected]> Signed-off-by: Brian Behlendorf <[email protected]> Closes #1082
* Move dracut directory to contribBrian Behlendorf2015-07-091-1/+1
| | | | | | | The dracut code is analogous to the initramfs code and as such it should be located in the contrib with initramfs for consistency. Signed-off-by: Brian Behlendorf <[email protected]>
* Style check shell scriptsTurbo Fredriksson2015-05-201-1/+13
| | | | | | | | | | | If the command "shellcheck" exists, then find all shell scripts and run shellcheck on them. * Use 'gcc' format with shellcheck. * Exclude zfs-script-config.sh (which isn't really a script).

* cstyle: Exclude several files from 'make checkstyle'Brian Behlendorf2013-12-181-1/+2
| | | | | | | | | The zfs_config.h header and *.mod.c files are both products of the build process. They must be excluded from the style check because they are not part of the pristine source. Signed-off-by: Brian Behlendorf <[email protected]> Issue #1821
* Add cstyle.pl utility and cstyle.1 man pageBrian Behlendorf2013-10-301-0/+3
| | | | | | | | | | | | | | | | | | | | | | | | Cstyle is the C source style checker used by Illumos. Since the original ZFS source was written using these style guidelines they must also be followed by ZoL for consistency. The checker has been added to the scripts directory and may be run on a per file basis. New patches should be careful to avoid introducing new style warnings. Additionally, the 'checkstyle' target has been added to the top level Makefile and can be used to check the entire source tree. While Zol has historically attempted to follow the SunOS style guide the lack of a rigorous style checker has allowed various warning to be introduced. Currently there are 2211 reported style violations and we want to gradually eliminate these from the tree. Note the cstyle.1 man page is provided under man/man1/cstyle.1 but since it is a developer utility it is not installed along with the other man pages.

* Use 'git describe' for working buildsBrian Behlendorf2013-03-221-0/+4
| | | | | | | | | | | | | | | | | When building from an arbitrary commit in the git tree it's useful for the resulting packages to be uniquely identifiable. Therefore, the build system has been updated to detect if your compiling in git tree. If you are building in a git tree, and there are commits after the last annotated tag. Then the <id>-<hash> component of 'git describe' will be used to overwrite the 'Release:' field in the META file. The only tricky part is that to ensure the 'make dist' tarball is built using the correct release. A dist-hook was added to the top level make file to rewrite the META file using the correct release.
