* Illumos #3588Matthew Ahrens2013-10-311-0/+34

* Posix ACL SupportMassimo Maggi2013-10-291-4/+18
| | | | | | | | | | | | | | | | | | | | | | | | 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. This change passes the POSIX Test Suite cleanly with the exception of xacl/00.t test 45 which is incorrect for Linux (Ext4 fails too). http://www.tuxera.com/community/posix-test-suite/ Signed-off-by: Massimo Maggi <[email protected]> Signed-off-by: Richard Yao <[email protected]> Signed-off-by: Brian Behlendorf <[email protected]> Closes #170

That means that the zfs/zpool utilities built from master are NOT compatible with the 0.6.2 kernel modules. Ensure you load the matching kernel modules from master after updating the utilities. Otherwise the zfs/zpool commands will be unable to interact with your pool and you will see errors similar to the following: $ zpool list failed to read pool configuration: bad address no pools available $ zfs list no datasets available Add zvol minor device creation to the new zfs_snapshot_nvl function. Remove the logging of the "release" operation in dsl_dataset_user_release_sync(). The logging caused a null dereference because ds->ds_dir is zeroed in dsl_dataset_destroy_sync() and the logging functions try to get the ds name via the dsl_dataset_name() function. I've got no idea why this particular code would have worked in Illumos. This code has subsequently been completely reworked in Illumos commit 3b2aab1 (3464 zfs synctask code needs restructuring). Squash some "may be used uninitialized" warning/erorrs. Fix some printf format warnings for %lld and %llu. Apply a few spa_writeable() changes that were made to Illumos in illumos/illumos-gate.git@cd1c8b8 as part of the 3112, 3113, 3114 and 3115 fixes. Add a missing call to fnvlist_free(nvl) in log_internal() that was added in Illumos to fix issue 3085 but couldn't be ported to ZoL at the time (zfsonlinux/zfs@9e11c73) because it depended on future work.

For consistenty with the vdev_disk.c code the upstream version leverages the Illumos bio interfaces. This makes sense for Illumos but not for ZoL for two reasons. 1) The vdev_disk.c code in ZoL has been rewritten to use the Linux block device interfaces which differ significantly from those in Illumos. Therefore, updating the vdev_file.c to use the Illumos interfaces doesn't get you consistency with vdev_disk.c. 2) Using the upstream patch as is would requiring implementing compatibility code for those Solaris block device interfaces in user and kernel space. That additional complexity could lead to confusion and doesn't buy us anything. For these reasons I've opted to simply move the existing vn_rdwr() as is in to the taskq function. This has the advantage of being low risk and easy to understand. Moving the vn_rdwr() function in to its own taskq thread also neatly avoids the possibility of a stack overflow. Finally, because of the additional work which is being handled by the free taskq the number of threads has been increased. The thread count under Illumos defaults to 100 but was decreased to 2 in commit 08d08e due to contention. We increase it to 8 until the contention can be address by porting Illumos #3581.

* Add snapdev=[hidden|visible] dataset propertyEric Dillmann2013-03-051-0/+11
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The new snapdev dataset property may be set to control the visibility of zvol snapshot devices. By default this value is set to 'hidden' which will prevent zvol snapshots from appearing under /dev/zvol/ and /dev/<dataset>/. When set to 'visible' all zvol snapshots for the dataset will be visible. This functionality was largely added because when automatic snapshoting is enabled large numbers of read-only zvol snapshots will be created. When creating these devices the kernel will attempt to read their partition tables, and blkid will attempt to identify any filesystems on those partitions. This leads to a variety of issues: 1) The zvol partition tables will be read in the context of the `modprobe zfs` for automatically imported pools. This is undesirable and should be done asynchronously, but for now reducing the number of visible devices helps. 2) Udev expects to be able to complete its work for a new block devices fairly quickly. When many zvol devices are added at the same time this is no longer be true. It can lead to udev timeouts and missing /dev/zvol links. 3) Simply having lots of devices in /dev/ can be aukward from a management standpoint. Hidding the devices your unlikely to ever use helps with this. Any snapshot device which is needed can be made visible by changing the snapdev property. NOTE: This patch changes the default behavior for zvols which was effectively 'snapdev=visible'. Signed-off-by: Brian Behlendorf <[email protected]> Closes #1235 Closes #945 Issue #956 Issue #756

* vdev_id support for device link aliasesNed Bass2012-12-031-4/+9
| | | | | | | | | | | | | | | | | | | | | | | | | | | | Add a vdev_id feature to map device names based on already defined udev device links. To increase the odds that vdev_id will run after the rules it depends on, increase the vdev.rules rule number from 60 to 69. With this change, vdev_id now provides functionality analogous to zpool_id and zpool_layout, paving the way to retire those tools. A defined alias takes precedence over a topology-derived name, but the two naming methods can otherwise coexist. For example, one might name drives in a JBOD with the sas_direct topology while naming an internal L2ARC device with an alias. For example, the following lines in vdev_id.conf will result in the creation of links /dev/disk/by-vdev/{d1,d2}, each pointing to the same target as the device link specified in the third field. # by-vdev # name fully qualified or base name of device link alias d1 /dev/disk/by-id/wwn-0x5000c5002de3b9ca alias d2 wwn-0x5000c5002def789e Also perform some minor vdev_id cleanup, such as removal of the unused -s command line option.

* Set zvol discard_granularity to the volblocksize.Etienne Dechamps2012-08-071-0/+1
| | | | | | | | | | | | | | | | | | Currently, zvols have a discard granularity set to 0, which suggests to the upper layer that discard requests of arbirarily small size and alignment can be made efficiently. In practice however, ZFS does not handle unaligned discard requests efficiently: indeed, it is unable to free a part of a block. It will write zeros to the specified range instead, which is both useless and inefficient (see dnode_free_range). With this patch, zvol block devices expose volblocksize as their discard granularity, so the upper layer is aware that it's not supposed to send discard requests smaller than volblocksize.

Extra care should be taken when updating to ensure both the kernel modules and utilities are updated. This change has reordered all of the new ioctl()s to the end of the list. This should help minimize this issue in the future.

* Linux 3.5 compat, end_writeback() changed to clear_inode()Richard Yao2012-07-231-0/+1
| | | | | | | | | | | | | | | | The end_writeback() function was changed by moving the call to inode_sync_wait() earlier in to evict(). This effecitvely changes the ordering of the sync but it does not impact the details of the zfs implementation. However, as part of this change end_writeback() was renamed to clear_inode() to reflect the new semantics. This change does impact us and clear_inode() now maps to end_writeback() for kernels prior to 3.5.

This interface used to take the child dentry and a bool describing if the parent is needed. NOTE: While updating this code I noticed that we do not currently cleanly handle the case where we're passed a connectable parent. This code should be audited to make sure we're doing the right thing. Signed-off-by: Richard Yao <[email protected]> Signed-off-by: Brian Behlendorf <[email protected]> Issue #784
