Support parallel build trees (VPATH builds) 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.

Support custom build directories and move includes One of the neat tricks an autoconf style project is capable of is allow configurion/building in a directory other than the source directory. The major advantage to this is that you can build the project various different ways while making changes in a single source tree. For example, this project is designed to work on various different Linux distributions each of which work slightly differently. This means that changes need to verified on each of those supported distributions perferably before the change is committed to the public git repo. Using nfs and custom build directories makes this much easier. I now have a single source tree in nfs mounted on several different systems each running a supported distribution. When I make a change to the source base I suspect may break things I can concurrently build from the same source on all the systems each in their own subdirectory. wget -c http://github.com/downloads/behlendorf/zfs/zfs-x.y.z.tar.gz tar -xzf zfs-x.y.z.tar.gz cd zfs-x-y-z ------------------------- run concurrently ---------------------- <ubuntu system> <fedora system> <debian system> <rhel6 system> mkdir ubuntu mkdir fedora mkdir debian mkdir rhel6 cd ubuntu cd fedora cd debian cd rhel6 ../configure ../configure ../configure ../configure make make make make make check make check make check make check This change also moves many of the include headers from individual incude/sys directories under the modules directory in to a single top level include directory. This has the advantage of making the build rules cleaner and logically it makes a bit more sense.

Combine libraries: spl, avl, efi, share, unicode. These libraries, which are an artifact of the ZoL development process, conflict with packages that are already in distribution: * libspl: SPL Programming Language * libavl: AVL for Linux * libefi: GRUB And these libraries are potential conflicts: * libshare: the Linux Mount Manager * libunicode: Perl and Python Recompose these five ZoL components into the four libraries that are conventionally provided by Solaris and FreeBSD systems: + libnvpair + libuutil + libzpool + libzfs This change resolves the name conflict, makes ZoL more compatible with existing software that uses autotools to detect ZFS, and allows pkg-zfs to better reflect the official Debian kFreeBSD packaging.

Add libtpool (thread pools) OpenZFS provides a library called tpool which implements thread pools for user space applications. Porting this library means the zpool utility no longer needs to borrow the kernel mutex and taskq interfaces from libzpool. This code was updated to use the tpool library which behaves in a very similar fashion. Porting libtpool was relatively straight forward and minimal modifications were needed. The core changes were: * Fully convert the library to use pthreads. * Updated signal handling. * lmalloc/lfree converted to calloc/free * Implemented portable pthread_attr_clone() function. Finally, update the build system such that libzpool.so is no longer linked in to zfs(8), zpool(8), etc. All that is required is libzfs to which the zcommon soures were added (which is the way it always should have been). Removing the libzpool dependency resulted in several build issues which needed to be resolved. * Moved zfeature support to module/zcommon/zfeature_common.c * Moved ratelimiting to to module/zfs/zfs_ratelimit.c * Moved get_system_hostid() to lib/libspl/gethostid.c * Removed use of cmn_err() in zcommon source * Removed dprintf_setup() call from zpool_main.c and zfs_main.c * Removed highbit() and lowbit() * Removed unnecessary library dependencies from Makefiles * Removed fletcher-4 kstat in user space * Added sha2 support explicitly to libzfs * Added highbit64() and lowbit64() to zpool_util.c Reviewed-by: Tony Hutter <hutter2@llnl.gov> Signed-off-by: Brian Behlendorf <behlendorf1@llnl.gov> Closes #6442

ABD optimized page allocation code * Convert ABD to use the Linux Kernel scatterlist implementation instead of the hand rolled one from illumos. * Scatter ABDs are preferentially populated with higher order compound pages from a single zone. Allocation size is progressively decreased until it can be satisfied without performing reclaim or compaction. * An alternate page allocator is provided for kernels older than 3.6 and for CONFIG_HIGHMEM systems. This allocator is designed as a fallback for maximum compatibility. * Extended abdstats to provide visibility in the the allocator. * Add cached value for PAGESIZE in userspace.

Support -fsanitize=address with --enable-asan When --enable-asan is provided to configure then build all user space components with fsanitize=address. For kernel support use the Linux KASAN feature instead. https://github.com/google/sanitizers/wiki/AddressSanitizer When using gcc version 4.8 any test case which intentionally generates a core dump will fail when using --enable-asan. The default behavior is to disable core dumps and only newer versions allow this behavior to be controled at run time with the ASAN_OPTIONS environment variable. Additionally, this patch includes some build system cleanup. * Rules.am updated to set the minimum AM_CFLAGS, AM_CPPFLAGS, and AM_LDFLAGS. Any additional flags should be added on a per-Makefile basic. The --enable-debug and --enable-asan options apply to all user space binaries and libraries. * Compiler checks consolidated in always-compiler-options.m4 and renamed for consistency. * -fstack-check compiler flag was removed, this functionality is provided by asan when configured with --enable-asan. * Split DEBUG_CFLAGS in to DEBUG_CFLAGS, DEBUG_CPPFLAGS, and DEBUG_LDFLAGS. * Moved default kernel build flags in to module/Makefile.in and split in to ZFS_MODULE_CFLAGS and ZFS_MODULE_CPPFLAGS. These flags are set with the standard ccflags-y kbuild mechanism. * -Wframe-larger-than checks applied only to binaries or libraries which include source files which are built in both user space and kernel space. This restriction is relaxed for user space only utilities. * -Wno-unused-but-set-variable applied only to libzfs and libzpool. The remaining warnings are the result of an ASSERT using a variable when is always declared. * -D_POSIX_PTHREAD_SEMANTICS and -D__EXTENSIONS__ dropped because they are Solaris specific and thus not needed. * Ensure $GDB is defined as gdb by default in zloop.sh.

Add proper library versioning The zfs libraries were never properly versioned. Since the API has remained static for quite some time this we never an issue. However, going forward they should be versioned. This commit versions all of the libraries to 1.0.0. From here on out this version must be updated to reflect changes to the library.

Generate libraries with correct DT_NEEDED entries Libraries that depend on other libraries should list them in ELF's DT_NEEDED field so that programs linking to them do not need to specify those libraries unless they depend on them as well. This is not the case in the current code and the consequence is that anything that needs a library must know its dependencies. This is fragile and caused GRUB2's configure script to break when a dependency was added on libblkid in libzfs. This resolves that problem by using LIBADD/LDADD to specify libraries in Makefile.am instead of LDFLAGS. This ensures that proper DT_NEEDED entries are generated and prevents GRUB2's configure script from breaking in the presence of a libblkid dependency. This also removes unneeded dependencies from various files. Signed-off-by: Richard Yao <ryao@gentoo.org> Signed-off-by: Brian Behlendorf <behlendorf1@llnl.gov> Issue #1751
