* configure fixesHarald van Dijk2020-07-011-19/+19
| | | | | | | | | | | | | | | | | | a+=b is not supported by all shells. It is equivalent to a=${a}b, so just rewrite it as that. This also fixes commit 9ea6c3d3, which intended to only make the definitions of _dracutdir, _udevdir, and _udevruledir conditional, but actually ensured that _initconfdir no longer got defined if _dracutdir was defined, and defined _udevdir to the value that should have been used for _udevruledir. This also fixes the fact that the checks introduced by commit 9ea6c3d3 could never work: ZFS_AC_PACKAGE was called before the configuration options were processed.

* Perform KABI checks in parallelBrian Behlendorf2019-10-011-0/+11
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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

* pyzfs: python3 support (build system)Brian Behlendorf2019-01-061-3/+7
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Almost all of the Python code in the respository has been updated to be compatibile with Python 2.6, Python 3.4, or newer. The only exceptions are arc_summery3.py which requires Python 3, and pyzfs which requires at least Python 2.7. This allows us to maintain a single version of the code and support most default versions of python. This change does the following: * Sets the default shebang for all Python scripts to python3. If only Python 2 is available, then at install time scripts which are compatible with Python 2 will have their shebangs replaced with /usr/bin/python. This is done for compatibility until Python 2 goes end of life. Since only the installed versions are changed this means Python 3 must be installed on the system for test-runner when testing in-tree. * Added --with-python=<2|3|3.4,etc> configure option which sets the PYTHON environment variable to target a specific python version. By default the newest installed version of Python will be used or the preferred distribution version when creating pacakges. * Fixed --enable-pyzfs configure checks so they are run when --enable-pyzfs=check and --enable-pyzfs=yes. * Enabled pyzfs for Python 3.4 and newer, which is now supported. * Renamed pyzfs package to python<VERSION>-pyzfs and updated to install in the appropriate site location. For example, when building with --with-python=3.4 a python34-pyzfs will be created which installs in /usr/lib/python3.4/site-packages/. * Renamed the following python scripts according to the Fedora guidance for packaging utilities in /bin - dbufstat.py -> dbufstat - arcstat.py -> arcstat - arc_summary.py -> arc_summary - arc_summary3.py -> arc_summary3 * Updated python-cffi package name. On CentOS 6, CentOS 7, and Amazon Linux it's called python-cffi, not python2-cffi. For Python3 it's called python3-cffi or python3x-cffi. * Install one version of arc_summary. Depending on the version of Python available install either arc_summary2 or arc_summary3 as arc_summary. The user output is only slightly different.

* Implement --enable-debuginfo to force debuginfoRichard Yao2017-08-291-1/+32
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Inspection of a Ubuntu 14.04 x64 system revealed that the config file used to build the kernel image differs from the config file used to build kernel modules by the presence of CONFIG_DEBUG_INFO=y: This in itself is insufficient to show that the kernel is built with debuginfo, but a cursory analysis of the debuginfo provided and the size of the kernel strongly suggests that it was built with CONFIG_DEBUG_INFO=y while the modules were not. Installing linux-image-$(uname -r)-dbgsym had no obvious effect on the debuginfo provided by either the modules or the kernel. The consequence is that issue reports from distributions such as Ubuntu and its derivatives build kernel modules without debuginfo contain nonsensical backtraces. It is therefore desireable to force generation of debuginfo, so we implement --enable-debuginfo. Since the build system can build both userspace components and kernel modules, the generic --enable-debuginfo option will force debuginfo for both. However, it also supports --enable-debuginfo=kernel and --enable-debuginfo=user for finer grained control. Enabling debuginfo for the kernel modules works by injecting CONFIG_DEBUG_INFO=y into the make environment. This is enables generation of debuginfo by the kernel build systems on all Linux kernels, but the build environment is slightly different int hat CONFIG_DEBUG_INFO has not been in the CPP. Adding -DCONFIG_DEBUG_INFO would fix that, but it would also cause build failures on kernels where CONFIG_DEBUG_INFO=y is already set. That would complicate its use in DKMS environments that support a range of kernels and is therefore undesireable. We could write a compatibility shim to enable CONFIG_DEBUG_INFO only when it is explicitly disabled, but we forgo doing that because it is unnecessary. Nothing in ZoL or the kernel uses CONFIG_DEBUG_INFO in the CPP at this time and that is unlikely to change. Enabling debuginfo for the userspace components is done by injecting -g into CPPFLAGS. This is not necessary because the build system honors the environment's CPPFLAGS by appending them to the actual CPPFLAGS used, but it is supported for consistency.

We “need” to know how much we will dirty so that we can check if we should fail this transaction with ENOSPC/EDQUOT, in dmu_tx_assign(). While the transaction is open (i.e. between dmu_tx_assign() and dmu_tx_commit() — typically less than a millisecond), we call dbuf_dirty() on the exact blocks that will be modified. Once this happens, the temporary accounting in tx_space_* is unnecessary, because we know exactly what blocks are newly dirtied; we call dnode_willuse_space() to track this more exact accounting. The fundamental problem causing this bug is that dmu_tx_hold_*() relies on the current state in the DMU (e.g. dn_nlevels) to predict how much will be dirtied by this transaction, but this state can change before we actually perform the transaction (i.e. call dbuf_dirty()). This bug will be fixed by removing the assertion that the tx_space_* accounting is perfectly accurate (i.e. we never dirty more than was predicted by dmu_tx_hold_*()). By removing the requirement that this accounting be perfectly accurate, we can also vastly simplify it, e.g. removing most of the logic in dmu_tx_count_*(). The new tx space accounting will be very approximate, and may be more or less than what is actually dirtied. It will still be used to determine if this transaction will put us over quota. Transactions that are marked by dmu_tx_mark_netfree() will be excepted from this check. We won’t make an attempt to determine how much space will be freed by the transaction — this was rarely accurate enough to determine if a transaction should be permitted when we are over quota, which is why dmu_tx_mark_netfree() was introduced in 2014. We also won’t attempt to give “credit” when overwriting existing blocks, if those blocks may be freed. This allows us to remove the do_free_accounting logic in dbuf_dirty(), and associated routines. This logic attempted to predict what will be on disk when this txg syncs, to know if the overwritten block will be freed (i.e. exists, and has no snapshots).

* Illumos Crypto Port module added to enable native encryption in zfsTom Caputi2016-07-201-3/+1
| | | | | | | | | | | | | | | | | | | | A port of the Illumos Crypto Framework to a Linux kernel module (found in module/icp). This is needed to do the actual encryption work. We cannot use the Linux kernel's built in crypto api because it is only exported to GPL-licensed modules. Having the ICP also means the crypto code can run on any of the other kernels under OpenZFS. I ended up porting over most of the internals of the framework, which means that porting over other API calls (if we need them) should be fairly easy. Specifically, I have ported over the API functions related to encryption, digests, macs, and crypto templates. The ICP is able to use assembly-accelerated encryption on amd64 machines and AES-NI instructions on Intel chips that support it.

For this purpose, following new defines are provided if instruction set is supported: - HAVE_SSE, - HAVE_SSE2, - HAVE_SSE3, - HAVE_SSSE3, - HAVE_SSE4_1, - HAVE_SSE4_2, - HAVE_AVX, - HAVE_AVX2. For detecting if an instruction set can be used in runtime, following functions are provided in (include/linux/simd_x86.h): - zfs_sse_available() - zfs_sse2_available() - zfs_sse3_available() - zfs_ssse3_available() - zfs_sse4_1_available() - zfs_sse4_2_available() - zfs_avx_available() - zfs_avx2_available() - zfs_bmi1_available() - zfs_bmi2_available() These function should be called once, on module load, or initialization. They are safe to use from user and kernel space. If an implementation is using more than single instruction set, both compiler and runtime support for all relevant instruction sets should be checked. Kernel fpu methods: - kfpu_begin() - kfpu_end() Use __get_cpuid_max and __cpuid_count from <cpuid.h> Both gcc and clang have support for these. They also handle ebx register in case it is used for PIC code.

* Add the ZFS Test SuiteBrian Behlendorf2016-03-161-2/+2

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

If this, the resulting dataset, already exists, destroy it. Then mount it on root. * If snapshot does not exist, use base dataset (the part before '@') as boot filesystem instead. * If no snapshot is specified on the 'root=' kernel command line, but there is an '@', then get a list of snapshots below that filesystem and ask the user which to use. * Clone with 'mountpoint=none' and 'canmount=noauto' - we mount manually and explicitly. * For sub-filesystems, that doesn't have a mountpoint property set, we use the 'org.zol:mountpoint' to keep track of it's mountpoint. * Allow rollback of snapshots instead of clone it and boot from the clone. * Allow mounting a root- and subfs with mountpoint=legacy set * Allow mounting a filesystem which is using nativ encryption. * Support all currently used kernel command line arguments All the different distributions have their own standard on what to specify on the kernel command line to boot of a ZFS filesystem. * Extra options: * zfsdebug=(on,yes,1) Show extra debugging information * zfsforce=(on,yes,1) Force import the pool * rollback=(on,yes,1) Rollback (instead of clone) the snapshot * Only try to import pool if it haven't already been imported * This will negate the need to force import a pool that have not been exported cleanly. * Support exclusion of pools to import by setting ZFS_POOL_EXCEPTIONS in /etc/default/zfs. * Support additional configuration variable ZFS_INITRD_ADDITIONAL_DATASETS to mount additional filesystems not located under your root dataset. * Include /etc/modprobe.d/{zfs,spl}.conf in the initrd if it/they exist. * Include the udev rule to use by-vdev for pool imports. * Include the /etc/default/zfs file to the initrd. * Only try /dev/disk/by-* in the initrd if USE_DISK_BY_ID is set. * Use /dev/disk/by-vdev before anything. * Add /dev as a last ditch attempt. * Fallback to using the cache file if that exist if nothing else worked. * Use /sbin/modprobe instead of built-in (BusyBox) modprobe.

Primarily used in initrd scripts to allow for when filesystem needed to boot (such as /usr, /opt, /var etc) isn't directly under the root dataset. * ZFS_POOL_EXCEPTIONS Exclude pools from being imported (in the initrd and/or init scripts). * ZFS_DKMS_ENABLE_DEBUG, ZFS_DKMS_ENABLE_DEBUG_DMU_TX, ZFS_DKMS_DISABLE_STRIP Set to control how dkms should build the dkms packages. * ZPOOL_IMPORT_PATH Set path(s) where "zpool import" should import pools from. This was previously the job of "USE_DISK_BY_ID" (which is still used for backwards compatibility) but was renamed to allow for better control of import path(s). * If old USE_DISK_BY_ID is set, but not new ZPOOL_IMPORT_PATH, then we set ZPOOL_IMPORT_PATH to sane defaults just to be on the safe side. * ZED_ARGS To allow for local options to zed without having to change the init script. * The import function, do_import(), imports pools by name instead of '-a' for better control of pools to import and from where. * If USE_DISK_BY_ID is set (for backwards compatibility), but isn't 'yes' then ignore it. * If pool(s) isn't found with a simple "zpool import" (seen it happen), try looking for them in /dev/disk/by-id (if it exists). Any duplicates (pools found with both commands) is filtered out. * IF we have found extra pool(s) this way, we must force USE_DISK_BY_ID so that the first, simple "zpool import $pool" is able to find it. * Fallback on importing the pool using the cache file (if it exists) only if 'simple' import (either with ZPOOL_IMPORT_PATH or the 'built in' defaults) didn't work. * The export function, do_export(), will export all pools imported, EXCEPT the root pool (if there is one). * ZED script from the Debian GNU/Linux packages added. * Refreshed ZED init script from behlendorf@5e7a660 to be portable so it may be used on both LSB and Redhat style systems. * If there is no pool(s) imported and zed successfully shut down, we will unload the zfs modules. * The function library file for the ZoL init script is installed as /etc/init.d/zfs-functions. * The four init scripts, the /etc/{defaults,sysconfig,conf.d}/zfs config file as well as the common function library is tagged as '%config(noreplace)' in the rpm rules file to make sure they are not replaced automatically if locally modifed. * Pitfals and workarounds: * If we're running from init, remove stale /etc/dfs/sharetab before importing pools in the zfs-import init script. * On Debian GNU/Linux, there's a 'sendsigs' script that will kill basically everything quite early in the shutdown phase and zed is/should be stopped much later than that. We don't want zed to be among the ones killed, so add the zed pid to list of pids for 'sendsigs' to ignore. * CentOS uses echo_success() and echo_failure() to print out status of command. These in turn uses "echo -n \0xx[etc]" to move cursor and choose colour etc. This doesn't work with the modified IFS variable we need to use in zfs-import for some reason, so work around that when we define zfs_log_{end,failure}_msg() for RedHat and derivative distributions. * All scripts passes ShellCheck (with one false positive in do_mount()).

* Disable GCCs aggressive loop optimizationBrian Behlendorf2014-01-141-0/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | GCC >+ 4.8's aggressive loop optimization breaks some of the iterators over the dn_blkptr[] pseudo-array in dnode_phys. Since dn_blkptr[] is defined as a single-element array, GCC believes an iterator can only access index 0 and will unroll the loop into a single iteration. One way to resolve the issue would be to cast the array to a pointer and fix all the iterators that might break. The only loop where it is known to cause a problem is this loop in dmu_objset_write_ready(): for (i = 0; i < dnp->dn_nblkptr; i++) bp->blk_fill += dnp->dn_blkptr[i].blk_fill; In the common case where dn_nblkptr is 3, the loop is only executed a single time and "i" is equal to 1 following the loop. The specific breakage caused by this problem is that the blk_fill of root block pointers wouldn't be set properly when more than one blkptr is in use (when no indrect blocks are needed). The simple reproducing sequence is: zpool create tank /tank.img zdb -ddddd tank 0 Notice that "fill=31", however, there are two L0 indirect blocks with "F=31" and "F=5". The fill count should be 36 rather than 31. This problem causes an assert to be hit in a simple "zdb tank" when built with --enable-debug. However, this approach was not taken because we need to be absolutely sure we catch all instances of this unwanted optimization. Therefore, the build system has been updated to detect if GCC supports the aggressive loop optimization. If it does the optimization will be explicitly disabled using the -fno-aggressive-loop-optimization option.
