* Accept udev and dracut paths specified by ./configureTurbo Fredriksson2014-06-113-7/+36
| | | | | | | | | | | | | | | | | | | | | | There are two common locations where udev and dracut components are commonly installed. When building packages using the 'make rpm|deb' targets check those common locations and pass them to rpmbuild. For non-standard configurations these values can be provided by the the following configure options: --with-udevdir=DIR install udev helpers [default=check] --with-udevruledir=DIR install udev rules [[UDEVDIR/rules.d]] --with-dracutdir=DIR install dracut helpers [default=check] When rebuilding using the source packages the per-distribution default values specified in the spec file will be used. This is the preferred way to build packages for a distribution but the ability to override the defaults is provided as a convenience.

* Move the libraries into separate packagesTurbo Fredriksson2014-06-021-5/+10
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | From day one the various ZFS libraries should have been placed in their own sub-packages. Primarily this allows for multiple major versions of the libraries to be concurrently installed. It also facilitates a smaller build environment by minimizing the required dependencies. The specific changes required to split the libraries from the utilities are as follows: * libzpool2, libnvpair1, libuutil1, and libzfs2 packages were added and contain the versioned shared libraries. The Fedora packaging guidelines discourage providing static libraries so they are not included in the packages. http://fedoraproject.org/wiki/Packaging:Guidelines#Packaging_Static_Libraries * The zfs-devel package was renamed libzfs2-devel and the new package obsoletes the old zfs-devel package. This package includes all the required headers for the libzpool2, libnvpair1, libuutil1, and libzfs2 libraries and their respective unversioned shared libraries. This package should eventually be split in to individual lib*-devel packages but it will still take some work to cleanly separate them. Therefore the libzfs2-devel package provides the expected lib*-devel packages so the all proper dependencies can still be created. http://fedoraproject.org/wiki/Packaging:Guidelines#Devel_Packages * Moved '/sbin/ldconfig' execution from the zfs packge to each of the new library packages as described by the packaging guidelines. http://fedoraproject.org/wiki/Packaging:Guidelines#Shared_Libraries * The /usr/share/doc/ files were moved in to the libzfs2-devel package. * Updated config/deb.am to be aware of the packaging changes. This ensures that 'deb-utils' make target converts all the resulting packages generated by the 'rpm-utils' target.

* Replace check for _POSIX_MEMLOCK w/ HAVE_MLOCKALLChris Dunlap2014-04-021-0/+3
| | | | | | | | | | | | | | | | | | | zed supports a '-M' cmdline opt to lock all pages in memory via mlockall(). The _POSIX_MEMLOCK define is checked to determine whether this function is supported. The current test assumes mlockall() is supported if _POSIX_MEMLOCK is non-zero. However, this test is insufficient according to mlock(2) and sysconf(3). If _POSIX_MEMLOCK is -1, mlockall() is not supported; but if _POSIX_MEMLOCK is 0, availability must be checked at runtime. This commit adds an autoconf check for mlockall() to user.m4. The zed code block for mlockall() is now guarded with a test for HAVE_MLOCKALL. If defined, mlockall() will be called and its runtime availability checked via its return value.

* Add defs for makefile installation dir varsChris Dunlap2014-03-313-0/+11
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Add macro definitions to AM_CPPFLAGS to propagate makefile installation directory variables for libexecdir, runstatedir, sbindir, and sysconfdir. https://www.gnu.org/software/autoconf/manual/autoconf-2.69/html_node/Installation-Directory-Variables.html A corollary is that you should not use these variables except in makefiles. For instance, instead of trying to evaluate datadir in configure and hard-coding it in makefiles using e.g., 'AC_DEFINE_UNQUOTED([DATADIR], ["$datadir"], [Data directory.])', you should add -DDATADIR='$(datadir)' to your makefile's definition of CPPFLAGS (AM_CPPFLAGS if you are also using Automake). The runstatedir directory is for "installing data files which the programs modify while they run, that pertain to one specific machine, and which need not persist longer than the execution of the program". https://www.gnu.org/prep/standards/html_node/Directory-Variables.html It will be defined by autoconf 2.70 or later, and default to "$(localstatedir)/run". http://git.savannah.gnu.org/gitweb/?p=autoconf.git;a=commit;h=a197431414088a417b407b9b20583b2e8f7363bd Signed-off-by: Chris Dunlap <[email protected]> Signed-off-by: Brian Behlendorf <[email protected]> Issue #2

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This adds systemd unit files replacing the functionality offered by the SysV init script found in etc/init.d. It has been developed and tested on Fedora 19, Fedora 20 and openSuSE 13.1. Four unit files and one target are offered. zfs-import-cache.service: Import pools from /etc/zfs/zpool.cache. This unit will wait for udev to settle. zfs-import-scan.service: Import pools by scanning /dev/disk/by-id for zvols. This unit will only run if /etc/zfs/zpool.cache is not present. This unit will wait for udev to settle zfs-mount.service: Mount ZFS native filesystems. It contains a dependency to be loaded before local-fs.target. zfs-share.service: Share NFS/SMB filesystems. This unit contains a dependency that will cause it to be restarted whenever the smb or nfs-server unit is restarted, restoring the shares added. zfs.target: This target pulls in the other units in order to start ZFS. It's the only unit that can be enabled/disabled, all other services are static and pulled in by dependencies. It will honour zfs=off and zfs=no options on the kernel command line.

* Disable GCCs aggressive loop optimizationBrian Behlendorf2014-01-144-2/+26
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

* Add full SELinux supportMatthew Thode2013-12-192-37/+0
| | | | | | | | | | | | | | | | | | | | | | | | | | | | Four new dataset properties have been added to support SELinux. They are 'context', 'fscontext', 'defcontext' and 'rootcontext' which map directly to the context options described in mount(8). When one of these properties is set to something other than 'none'. That string will be passed verbatim as a mount option for the given context when the filesystem is mounted. For example, if you wanted the rootcontext for a filesystem to be set to 'system_u:object_r:fs_t' you would set the property as follows: $ zfs set rootcontext="system_u:object_r:fs_t" storage-pool/media This will ensure the filesystem is automatically mounted with that rootcontext. It is equivalent to manually specifying the rootcontext with the -o option like this: $ zfs mount -o rootcontext=system_u:object_r:fs_t storage-pool/media By default all four contexts are set to 'none'. Further information on SELinux contexts is detailed in mount(8) and selinux(8) man pages.

* Posix ACL SupportMassimo Maggi2013-10-293-0/+331
| | | | | | | | | | | | | | | | | | | | | | | | This change adds support for Posix ACLs by storing them as an xattr which is common practice for many Linux file systems. Since the Posix ACL is stored as an xattr it will not overwrite any existing ZFS/NFSv4 ACLs which may have been set. The Posix ACL will also be non-functional on other platforms although it may be visible as an xattr if that platform understands SA based xattrs. By default Posix ACLs are disabled but they may be enabled with the new 'aclmode=noacl|posixacl' property. Set the property to 'posixacl' to enable them. If ZFS/NFSv4 ACL support is ever added an appropriate acltype will be added.

* Fix libblkid supportRichard Yao2013-10-101-7/+26
| | | | | | | | | | | | | | | | | | | | | | | | | libblkid support is dormant because the autotools check is broken and liblkid identifies ZFS vdevs as "zfs_member", not "zfs". We fix that with a few changes: First, we fix the libblkid autotools check to do a few things: 1. Make a 64MB file, which is the minimum size ZFS permits. 2. Make 4 fake uberblock entries to make libblkid's check succeed. 3. Return 0 upon success to make autotools use the success case. 4. Include stdlib.h to avoid implicit declration of free(). 5. Check for "zfs_member", not "zfs" 6. Make --with-blkid disable autotools check (avoids Gentoo sandbox violation) 7. Pass '-lblkid' correctly using LIBS not LDFLAGS. Second, we change the libblkid support to scan for "zfs_member", not "zfs". This makes --with-blkid work on Gentoo.

* Linux 3.11 compat: fops->iterate()Richard Yao2013-08-152-0/+44
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Commit torvalds/linux@2233f31aade393641f0eaed43a71110e629bb900 replaced ->readdir() with ->iterate() in struct file_operations. All filesystems must now use the new ->iterate method. To handle this the code was reworked to use the new ->iterate interface. Care was taken to keep the majority of changes confined to the ZPL layer which is already Linux specific. However, minor changes were required to the common zfs_readdir() function. Compatibility with older kernels was accomplished by adding versions of the trivial dir_emit* helper functions. Also the various *_readdir() functions were reworked in to wrappers which create a dir_context structure to pass to the new *_iterate() functions. Unfortunately, the new dir_emit* functions prevent us from passing a private pointer to the filldir function. The xattr directory code leveraged this ability through zfs_readdir() to generate the list of xattr names. Since we can no longer use zfs_readdir() a simplified zpl_xattr_readdir() function was added to perform the same task.

* Fix arc_adapt() spinning in iterate_supers_type()Brian Behlendorf2013-07-172-0/+40
| | | | | | | | | | | | | | | | | | | | | | | | | | The iterate_supers_type() function which was introduced in the 3.0 kernel was supposed to provide a safe way to call an arbitrary function on all super blocks of a specific type. Unfortunately, because a list_head was used a bug was introduced which made it possible for iterate_supers_type() to get stuck spinning on a super block which was just deactivated. This can occur because when the list head is removed from the fs_supers list it is reinitialized to point to itself. If the iterate_supers_type() function happened to be processing the removed list_head it will get stuck spinning on that list_head. The bug was fixed in the 3.3 kernel by converting the list_head to an hlist_node. However, to resolve the issue for existing 3.0 - 3.2 kernels we detect when a list_head is used. Then to prevent the spinning from occurring the .next pointer is set to the fs_supers list_head which ensures the iterate_supers_type() function will always terminate.

Tested with xfstests 285 and 286. All tests pass except for 7-9 of 285 which try to reserve blocks first via fallocate(2) and fail because fallocate(2) is not yet supported. Note that the filp->f_lock spinlock did not exist prior to Linux 2.6.30, but we avoid the need for autotools check by virtue of the fact that SEEK_DATA/SEEK_HOLE support was not added until Linux 3.1. An autoconf check was added for lseek_execute() which is currently a private function but the expectation is that it will be exported perhaps as early as Linux 3.11.

* Configure --with-spl{-obj} auto-detect cleanupBrian Behlendorf2013-03-131-37/+49
| | | | | | | | | | | | | | | | | | | | | | | | | | Because the install location for the spl/zfs-devel headers was changed we need to refresh the auto-detect code. Note that for packaging which already explicitly calls --with-spl{-obj} nothing has changed. The updated code is now structured like that in ZFS_AC_KERNEL and should be cleaner and easier to maintain. In addition, it's stricter about detecting a valid source and object directory. It requires: * The source directory contains the file 'spl.release' * The object directory contains the file 'spl_config.h' * The following paths will be checked. Notice the /var/lib/ and /usr/src paths require that the spl and zfs version be matched. This is done to prevent accidentally mixing releases. dnl # 1) /var/lib/dkms/spl/<version>/build dnl # 2) /usr/src/spl-<version>/<kernel-version> dnl # 3) /usr/src/spl-<version> dnl # 4) ../spl dnl # 5) /usr/src/kernels/<kernel-version> Signed-off-by: Brian Behlendorf <[email protected]>
* Remove ARCH packagingBrian Behlendorf2013-03-062-95/+3
| | | | | | | | | | | | | | The kernel modules are now available in the Arch User Repository (AUR) via zfs. Since their packaging is maintained and superior to ours it is being removed from the tree. https://wiki.archlinux.org/index.php/ZFS Now that various distributions are picking up the packages we should eventually be able to remove most of this infrastructure.

* Add --with-dracutdir configure optionBrian Behlendorf2013-03-062-0/+9
| | | | | | | | | | | | | The standard dracut directory has moved from /usr/share/dracut to /usr/lib/dracut. To ensure the dracut modules get installed in the correct location provide a --with-dracutdir configure option to set the path. The default install location has been updated to /usr/lib/dracut which is used by more current versions of Fedora. However, this default is overriden by the RPM packaging for consistency.

* Eliminate runtime function pointer mods in autotools checksRichard Yao2013-03-0410-150/+113
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | PaX/GrSecurity patched kernels implement a dialect of C that relies on a GCC plugin for enforcement. A basic idea in this dialect is that function pointers in structures should not change during runtime. This causes code that modifies function pointers at runtime to fail to compile in many instances. The autotools checks rely on whether or not small test cases compile against a given kernel. Some autotools checks assume some default case if other cases fail. When one of these autotools checks tests a PaX/GrSecurity patched kernel by modifying a function pointer at runtime, the default case will be used. Early detection of such situations is possible by relying on compiler warnings, which are compiler errors when --enable-debug is used. Unfortunately, very few people build ZFS with --enable-debug. The more common situation is that these issues manifest themselves as runtime failures in the form of NULL pointer exceptions. Previous patches that addressed such issues with PaX/GrSecurity compatibility largely relied on rewriting autotools checks to avoid runtime function pointer modification or the addition of PaX/GrSecurity specific checks. This patch takes the previous work to its logical conclusion by eliminating the use of runtime function pointer modification. This permits the removal of PaX-specific autotools checks in favor of ones that work across all supported kernels. This should resolve issues that were reported to occur with PaX/GrSecurity-patched Linux 3.7.5 kernels on Gentoo Linux. https://bugs.gentoo.org/show_bug.cgi?id=457176 We should be able to prevent future regressions in PaX/GrSecurity compatibility by ensuring that all changes to ZFSOnLinux avoid runtime function pointer modification. At the same time, this does not solve the issue of silent failures triggering default cases in the autotools check, which is what permitted these regressions to become runtime failures in the first place. This will need to be addressed in a future patch.

* Remove the bio_empty_barrier() check.Etienne Dechamps2013-02-242-20/+0
| | | | | | | | | | | | | | | | | | | | | | | To determine whether the kernel is capable of handling empty barrier BIOs, we check for the presence of the bio_empty_barrier() macro, which was introduced in 2.6.24. If this macro is defined, then we can flush disk vdevs; if it isn't, then flushing is disabled. Unfortunately, the bio_empty_barrier() macro was removed in 2.6.37, even though the kernel is still capable of handling empty barrier BIOs. As a result, flushing is effectively disabled on kernels >= 2.6.37, meaning that starting from this kernel version, zfs doesn't use barriers to guarantee on-disk data consistency. This is quite bad and can lead to potential data corruption on power failures. This patch fixes the issue by removing the configure check for bio_empty_barrier(), as we don't support kernels <= 2.6.24 anymore. Thanks to Richard Kojedzinszky for catching this nasty bug.

* Use -Werror for all kernel configure tests.Etienne Dechamps2013-02-244-11/+1
| | | | | | | | | | | | | As a matter of fact, we're already using -Werror for most tests because of a bug in kernel-bio-empty-barrier.m4 which sets -Werror without reverting it afterwards. This meant that all tests which ran after this one was using -Werror. This patch simply makes it clear that we're using -Werror and makes the code more readable and more predictable.

* Remove NPTL_GUARD_WITHIN_STACKBrian Behlendorf2013-01-292-57/+0
| | | | | | | | | | | | | | | | | Commit 4b2f65b253952c5103311cc8bb4b8cdc6836fd7e increased the user space stack by 4x to resolve certain stack overflows. As such it no longer makes sense to worry about a single extra page which might or might not be part of the process stack. There is now ample headroom for normal usage. By eliminating this configure check we are also resolving the following segfault which intentionally occurs at configure time and may be logged in dmesg. conftest[22156]: segfault at 7fbf18a47e48 ip 00000000004007fe sp 00007fbf18a4be50 error 6 in conftest[400000+1000] Signed-off-by: Brian Behlendorf <[email protected]>
* Linux 2.6.26 compat, lookup_bdev()Brian Behlendorf2013-01-282-0/+18
| | | | | | | | | | | | | | | | | | | It's doubtful many people were impacted by this but commit 6c28567 accidentally broke ZFS builds for 2.6.26 and earlier kernels. This commit depends on the lookup_bdev() function which exists in 2.6.26 but wasn't exported until 2.6.27. The availability of the function isn't critical so a wrapper is introduced which returns ERR_PTR(-ENOTSUP) when the function isn't defined. This will have the effect of causing zvol_is_zvol() to always fail for 2.6.26 kernels. This in turn means vdevs will always get opened concurrently which is good for normal usage. This will only become an issue if your using a zvol as a vdev in another pool. In which case you really should be using a newer kernel anyway.

* Use sb->s_d_op default dentry operationsBrian Behlendorf2013-01-182-0/+20

* Fix false ENOENT on snapshot control dentriesNed Bass2013-01-162-0/+67
| | | | | | | | | | | | | | | | | | | | | | Lookups in the snapshot control directory for an existing snapshot fail with ENOENT if an earlier lookup failed before the snapshot was created. This is because the earlier lookup causes a negative dentry to be cached which is never invalidated. The bug can be reproduced as follows (the second ls should succeed): $ ls /tank/.zfs/snapshot/s ls: cannot access /tank/.zfs/snapshot/s: No such file or directory $ zfs snap tank@s $ ls /tank/.zfs/snapshot/s ls: cannot access /tank/.zfs/snapshot/s: No such file or directory To remedy this, always invalidate cached dentries in the snapshot control directory. Since these entries never exist on disk there is no significant performance penalty for the extra lookups. Signed-off-by: Brian Behlendorf <[email protected]> Closes #1192
* Only use gcc -Wunused-but-set-variable when availableBrian Behlendorf2013-01-1020-20/+20
| | | | | | | | | | | | | | | | | | | Certain versions of gcc generate an 'unrecognized command line option' error message when -Wunused-but-set-variable is used unconditionally. This in turn can cause several of the autoconf tests to misdetect an interface. Now, the use of -Wunused-but-set-variable in the autoconf tests was introduced by commit b9c59ec8 to address a gcc 4.6 compatibility problem. So we really only need to pass this option for version of gcc which are known to support it. Therefore, the tests have been updated to use the result of the existing ZFS_AC_CONFIG_ALWAYS_NO_UNUSED_BUT_SET_VARIABLE which determines if gcc supports this option.

* Update SAs when an inode is dirtiedBrian Behlendorf2012-12-142-0/+24
| | | | | | | | | | | | | | | | | | | | | | | | | | | Revert the portion of commit d3aa3ea which always resulted in the SAs being update when an mmap()'ed file was closed. That change accidentally resulted in unexpected ctime updates which upset tools like git. That was always a horrible hack and I'm happy it will never make it in to a tagged release. The right fix is something I initially resisted doing because I was worried about the additional overhead. However, in hindsight the overhead isn't as bad as I feared. This patch implemented the sops->dirty_inode() callback which is unsurprisingly called when an inode is dirtied. We leverage this callback to keep the znode SAs strictly in sync with the inode. However, for now we're going to go slowly to avoid introducing any new unexpected issues by only updating the atime, mtime, and ctime. This will cover the callpath of most concern to us. ->filemap_page_mkwrite->file_update_time->update_time-> mark_inode_dirty_sync->__mark_inode_dirty->dirty_inode Signed-off-by: Brian Behlendorf <[email protected]> Closes #764 Closes #1140
