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.

ZTEST: Always enable asserts The build for ztest always enabled debug information but does not enable asserts unless --enable-debug is used. This will always enable asserts in the ztest code.

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.

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

Cleanup linking I noticed during code review of zfsonlinux/zfs#4385 that the author of a commit had peppered the various Makefile.am files with `$(TIRPC_LIBS)` when putting it into `lib/libspl/Makefile.am` should have sufficed. Upon further examination, it seems that he had copied what we do with `$(ZLIB)`. We also have a bit of that with `-ldl` too. Unfortunately, what we do is wrong, so lets fix it to set a good example for future contributors. In addition, we have multiple `-lz` and `-luuid` passed to the compiler because each `AC_CHECK_LIB` adds it to `$LIBS`. That is somewhat annoying to see, so we switch to `AC_SEARCH_LIBS` to avoid it. This is consistent with the recommendation to use `AC_SEARCH_LIBS` over `AC_CHECK_LIB` by autotools upstream: https://www.gnu.org/software/autoconf/manual/autoconf-2.66/html_node/Libraries.html In an ideal world, this would translate into improvements in ELF's `DT_NEEDED` entries, but that is not the case because of a couple of bugs in libtool. The first bug causes libtool to overlink by using static link dependencies for dynamic linking: https://wiki.mageia.org/en/Overlinking_issues_in_packaging#libtool_issues The workaround for this should be to pass `-Wl,--as-needed` in `LDFLAGS`. That leads us to the second bug, where libtool passes `LDFLAGS` after the libraries are specified and `ld` will only honor `--as-needed` on libraries specified before it: https://sigquit.wordpress.com/2011/02/16/why-asneeded-doesnt-work-as-expected-for-your-libraries-on-your-autotools-project/ There are a few possible workarounds for the second bug. One is to either patch the compiler spec file to specify `-Wl,--as-needed` or pass `-Wl,--as-needed` via `CC` like `CC='gcc -Wl,--as-needed'` so that it is specified early. Another is to patch ltmain.sh like Gentoo does: https://gitweb.gentoo.org/repo/gentoo.git/tree/eclass/ELT-patches/as-needed Without one of those workarounds, this cleanup provides no benefit in terms of `DT_NEEDED` entry generation. It should still be an improvement because it nicely simplifies the code while encouraging good habits when patching autotools scripts.
