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

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.

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.

Native Encryption for ZFS on Linux This change incorporates three major pieces: The first change is a keystore that manages wrapping and encryption keys for encrypted datasets. These commands mostly involve manipulating the new DSL Crypto Key ZAP Objects that live in the MOS. Each encrypted dataset has its own DSL Crypto Key that is protected with a user's key. This level of indirection allows users to change their keys without re-encrypting their entire datasets. The change implements the new subcommands "zfs load-key", "zfs unload-key" and "zfs change-key" which allow the user to manage their encryption keys and settings. In addition, several new flags and properties have been added to allow dataset creation and to make mounting and unmounting more convenient. The second piece of this patch provides the ability to encrypt, decyrpt, and authenticate protected datasets. Each object set maintains a Merkel tree of Message Authentication Codes that protect the lower layers, similarly to how checksums are maintained. This part impacts the zio layer, which handles the actual encryption and generation of MACs, as well as the ARC and DMU, which need to be able to handle encrypted buffers and protected data. The last addition is the ability to do raw, encrypted sends and receives. The idea here is to send raw encrypted and compressed data and receive it exactly as is on a backup system. This means that the dataset on the receiving system is protected using the same user key that is in use on the sending side. By doing so, datasets can be efficiently backed up to an untrusted system without fear of data being compromised.

Fix libzfs_core changes to follow GNU libtool guidelines The GNU libtool documentation states to start with a version of 0:0:0, rather than 1:1:0. Illumos uses the name libzfs_core.so.1, so to be consistent, we should go with 1:0:0. http://www.gnu.org/software/libtool/manual/libtool.html#Updating-version-info The GNU libtool documentation also provides guidence on how the version information should be incremented. Doing this does a SONAME bump of the libzfs and libzpool libraries. This is particularly important on Gentoo because a SONAME bump enables portage to retain the older libraries until any packages that link to them are rebuilt. The main example of this is GRUB2's grub2-mkconfig, which will break unless it is rebuilt against the new libraries.
