* OpenZFS 5380 - receive of a send -p stream doesn't need to try renaming ↵Andriy Gapon2017-04-091-3/+3

All of the above are not necessary if we are receiving a stream for a single dataset that has been generated with zfs send -p, that is, a stream that includes properties. zfs_receive_one() already takes care of applying the properties to the received datasets.

* glibc 2.5 compat: use correct header for makedev() et al.Olaf Faaland2017-03-312-1/+6
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | In glibc 2.5, makedev(), major(), and minor() are defined in sys/sysmacros.h. They are also defined in types.h for backward compatability, but using these definitions triggers a compile warning. This breaks the ZFS build, as it builds with -Werror. autoconf email threads indicate these macros may be defined in sys/mkdev.h in some cases. This commit adds configure checks to detect where makedev() is defined: sys/sysmacros.h sys/mkdev.h It assumes major() and minor() are defined in the same place. The libspl types.h then includes sys/sysmacros.h (preferred) or sys/mkdev.h (2nd choice) if one of those defines makedev(). This is done before including the system types.h. An alternative would be to remove uses of major, minor, and makedev, instead comparing the st_dev returned from stat64. These configure checks would then be unnecessary. This change revealed that __NORETURN was being defined unnecessarily in libspl/include/sys/sysmacros.h. That definition is removed. The files in which __NORETURN are used all include types.h, and so all will get the definition provided by feature_tests.h Reviewed-by: Brian Behlendorf <[email protected]> Signed-off-by: Olaf Faaland <[email protected]> Closes #5945

* Fix `zpool status -v` error messageBrian Behlendorf2017-03-221-6/+6
| | | | | | | | | | | | | | | | | | | | | | | | | When a pool is suspended it's impossible to read the list of damaged files from disk. This would result in a generic misleading "insufficient permissions" error message. Update zpool_get_errlog() to use the standard zpool error logging functions to generate a useful error message. In this case: errors: List of errors unavailable: pool I/O is currently suspended This patch does not address the related issue of potentially not being able to resume a suspend pool when the underlying device names have changed. Additionally, remove the error handling from zfs_alloc() in zpool_get_errlog() for readability since this function can never fail.

* libspl: Fix incorrect use of platform defines on sparc64John Paul Adrian Glaubitz2017-03-221-2/+2
| | | | | | | | | | | | | | | | libspl tries to detect sparc64 by checking whether __sparc64__ is defined. Unfortunately, this assumption is not correct as sparc64 does not define __sparc64__ but it defines __sparc__ and __arch64__ instead. This leads to sparc64 being detected as 32-Bit sparc and the build fails because both _ILP32 and _LP64 are defined in this case. To fix the problem, remove the checks for __sparc64__ and just check __arch64__ if a sparc host was previously detected with __sparc__.

* Fix nfs snapdir automountChunwei Chen2017-03-081-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | The current implementation for allowing nfs to access snapdir is very buggy. It uses a special fh for snapdirs, such that the next time nfsd does fh_to_dentry, it actually returns the root inode inside the snapshot. So nfsd never knows it cross a mountpoint. The problem is that nfsd will not hold a reference on the vfsmount of the snapshot. This cause auto unmounter to unmount the snapshot even though nfs is still holding dentries in it. To fix this, we return the inode for the snapdirs themselves. However, we also trigger automount upon fh_to_dentry, and return ESTALE so nfsd will revalidate and see the mountpoint and do crossmnt. Because nfsd will now be aware that these are different filesystems users must add crossmnt to their export options to access snapshot directories.

This is important in the case where a disk that is labeled with vdev_enc_sysfs_path is pulled out and put into another enclosure.

* OpenZFS 7745 - print error if lzc_* is called before libzfs_core_initGeorge Melikov2017-01-312-3/+24
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The problem is that consumers of `libZFS_Core` that forget to call `libzfs_core_init()` before calling any other function of the library are having a hard time realizing their mistake. The library's internal file descriptor is declared as global static, which is ok, but it is not initialized explicitly; therefore, it defaults to 0, which is a valid file descriptor. If `libzfs_core_init()`, which explicitly initializes the correct fd, is skipped, the ioctl functions return errors that do not have anything to do with `libZFS_Core`, where the problem is actually located. Even though assertions for that existed within `libZFS_Core` for debug builds, they were never enabled because the `-DDEBUG` flag was missing from the compiler flags. This patch applies the following changes: 1. It adds `-DDEBUG` for debug builds of `libZFS_Core` and `libzfs`, to enable their assertions on debug builds. 2. It corrects an assertion within `libzfs`, where a function had been spelled incorrectly (`zpool_prop_unsupported()`) and nobody knew because the `-DDEBUG` flag was missing, and the preprocessor was taking that part of the code away. 3. The library's internal fd is initialized to `-1` and `VERIFY` assertions have been placed to check that the fd is not equal to `-1` before issuing any ioctl. It is important here to note, that the `VERIFY` assertions exist in both debug and non-debug builds. 4. In `libzfs_core_fini` we make sure to never increment the refcount of our fd below 0, and also reset the fd to `-1` when no one refers to it. The reason for this, is for the rare case that the consumer closes all references but then calls one of the library's functions without using `libzfs_core_init()` first, and in the mean time, a previous call to `open()` decided to reuse our previous fd. This scenario would have passed our assertion in non-debug builds. 5. Once the `ASSERTION` macros were enabled again, two tests from the test suite were failing in `libzfs_sendrecv.c` at a `ZIO_CHECKSUM_IS_ZERO` check within `dump_record()`. We now zero the kernel filled checksums in all `dmu_replay_record`s that we read in `cksummer()`, except the ones that are of type `DRR_BEGIN`. I considered making all assertions available for both debug and non-debug builds, but I figured that it would not be appropriate if, for example, an outside consumer of `libZFS_Core` suddenly triggers an assertion failure because they happened to call `libzfs_core_fini()`, even if previously the reference counter was `0`. Therefore, all the reference counter related assertions are only enabled for debug builds, and fd related assertions are enabled for debug and non-debug builds. Porting notes: - `ASSERT3S(g_refcount, >, 0);` added to `recv_impl` in lib/libzfs_core/libzfs_core.c .

* Add -c to zpool iostat & status to run commandTony Hutter2016-11-292-97/+88
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch adds a command (-c) option to zpool status and zpool iostat. The -c option allows you to run an arbitrary command on each vdev and display the first line of output in zpool status/iostat. The environment vars VDEV_PATH and VDEV_UPATH are set to the vdev's path and "underlying path" before running the command. For device mapper, multipath, or partitioned vdevs, VDEV_UPATH is the actual underlying /dev/sd* disk. This can be useful if the command you're running requires a /dev/sd* device. The patch also uses /sys/block/<dev>/slaves/ to lookup the underlying device instead of using libdevmapper. This not only removes the libdevmapper requirement at build time, but also allows you to resolve device mapper devices without being root. This means that UDEV_UPATH get set correctly when running zpool status/iostat as an unprivileged user. Example: $ zpool status -c 'echo I am $VDEV_PATH, $VDEV_UPATH' NAME STATE READ WRITE CKSUM mypool ONLINE 0 0 0 mirror-0 ONLINE 0 0 0 mpatha ONLINE 0 0 0 I am /dev/mapper/mpatha, /dev/sdc sdb ONLINE 0 0 0 I am /dev/sdb1, /dev/sdb Reviewed-by: Giuseppe Di Natale <[email protected]> Reviewed-by: Brian Behlendorf <[email protected]> Signed-off-by: Tony Hutter <[email protected]> Closes #5368

* Fix 'zpool import' detection issueBrian Behlendorf2016-11-141-3/+16
| | | | | | | | | | | | | | | | | | | | | Before adding the entry to the configuration verify that the device can be opened exclusively. This ensures that as long as multipathd is running the underlying multipath devices, which otherwise appear identical to their /dev/mapper counterpart, are pruned from the configuration. Failure to do so can result in a result in the vdev appearing as UNAVAIL when the vdev path provided to the kernel can't be opened exclusively. This check would normally be performed in zpool_open_func() but placing it there would result in false positives because it is called concurrently for many devices.

* Fix 'zpool import' detection issuesBrian Behlendorf2016-11-072-35/+105
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch addresses multiple 'zpool import' block device indentification problems which are most likely to occur on a system configured to use blkid, by_vdev paths, multipath and failover. The symptom most commonly observed is the import uses different path names to import the pool than would normally be expected. * When using blkid to identify vdevs the listed devices may be added to the cache in any order. In order to apply the preferred search order heuristic a zfs_path_order() function was added to calculate the order given full path names. * Since it's possible to have multiple block devices with different vdev guids which refer to the same ZPOOL_CONFIG_PATH the slice cache must be indexed by guid and name. By avoiding collisions the preferred ordering can be maintaining even when multiple block devices claim the same ZPOOL_CONFIG_PATH. The preferred sorting by partition was never benefitial for a Linux system and was removed as part of this change. * When adding entries to the blkid cache avl_find/avl_insert are used instead of avl_add because collisions are possible and must be handled gracefully. * For pools using multipath devices there are, at a minimum, three devices where a vdev label may be read. They are the dm-* device and each underlying /dev/sd* device. Due to the way the block cache is implemented each of these devices may have a different cached copy of the vdev label. This can result in "ghost pools" which appear to persist even after a 'zpool labelclear' has been done to the dm-* device. In order to prevent this the vdev label is read with O_DIRECT in order to bypass any caching to get the on-disk version. * When opening a block device verify that vdev guid read from the disk matches the expected vdev guid. This allows for bad labels to be filtered out. Reviewed-by: Tony Hutter <[email protected]> Signed-off-by: Brian Behlendorf <[email protected]> Closes #5359
