* Move strlcat, strlcpy, and strnlenBrian Behlendorf2018-11-206-162/+54
| | | | | | | | | | | | | | | | | | | | | | | | Move strlcat() and strlcpy() from .c source files in to the libspl string.h header. By changing these compatibility functions to static inline functions they can included as needed without requiring linking with the libspl.so library. Remove strnlen() which is barely used in the source, and has been provided by glibc since v2.10. Finally, convert four instances of strncpy() to strlcpy() in libzfs_input_check.c which were causing build warnings when compiling with gcc 8.2.1. For example: libzfs_input_check.c: In function ‘zfs_destroy’: libzfs_input_check.c:651:9: error: ‘strncpy’ specified bound \ 4096 equals destination size [-Werror=stringop-truncation] (void) strncpy(zc.zc_name, dataset, sizeof (zc.zc_name)); ^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ Reviewed-by: Olaf Faaland <[email protected]> Reviewed-by: Richard Laager <[email protected]> Signed-off-by: Brian Behlendorf <[email protected]> Closes #8116

| | | | | | | | | | | | | | filetest_001_pos consumes the output using read -r, assigning each field to a variable. The problem comes when a vdev is marked degraded, which appends extra fields to the line. This causes the trailing text to be treated as part of the `cksum` variable. Using awk instead of read -r allows us to extract the checksum error count from the output whether the vdev is degraded or not.

* Allow spaces in pool names for cmdline argumentkpande2018-11-111-0/+3
| | | | | | | | | | | | | | | | | | | | | PR #8114 quoted the ${ENCRYPTIONROOT} parameter to ensure we don't lose spaces when unlocking root filesystem in the off chance that it has a space in its name. Unfortunately, dracut and initramfs-tools do not actually get the quotes from the cmdline. If we use root=ZFS="root pool/filesystem name" the script still only sees root=ZFS=root and no quotation marks. Because + is a reserved character in ZFS, it's used as a placeholder for spaces in the kernel cmdline. In this way, root=ZFS=root+pool/filesystem+name will properly expand by replacing the character with sed (POSIX compliant method).

* ztest: reduce gangblock creationBrian Behlendorf2018-11-052-3/+6
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | In order to validate the gang block code ztest is configured to artificially force a fraction of large blocks to be written as gang blocks. The default setting chosen for this was to write 25% of all blocks 32k or larger using gang blocks. The confluence of an unrealistically large number of gang blocks, the aggressive fault injection done by ztest, and the split segment reconstruction logic introduced by device removal has resulted in the following type of failure: zdb -bccsv -G -d ... exit code 3 Specifically, zdb was unable to open the pool because it was unable to reconstruct a damaged block. Manual investigation of multiple failures clearly showed that the block could be reconstructed. However, due to the large number of damaged segments (>35) it could not be done in the allotted time. Furthermore, the large number of gang blocks was determined to be the reason for the unrealistically large number of damaged segments. In order to make this situation less likely, this change both increases the forced gang block size to 64k and reduces the frequency to 3% of blocks.

* bpobj_enqueue_subobj() should copy small subobj'sMatthew Ahrens2018-10-311-40/+176
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | When we delete a snapshot, we consolidate some bpobj's together because we no longer need to keep their entries in separate buckets. This is done in constant time by including the "sub" bpobj by reference in the parent bpobj. After many snapshots have been deleted, we may have many sub-bpobj's. Usually, most sub-bpobj's don't contain many BP's. Compared to this small payload, the sub-bpobj is relatively heavyweight since it is a object in the MOS. A common scenario on a long-lived pool is for the vast majority of MOS objects to be small sub-bpobj's. To improve this situation, when consolidating bpobj's together, bpobj_enqueue_subobj() can copy the contents of small bpobj's into the parent, and then delete the enqueued bpobj, rather than including it by reference. Since this copying is limited in size (to one block), the consolidation is still constant time, though with a larger constant due to reading in the one block of the enqueued bpobj. This idea and mechanism are similar to how we handle "sub-subobj's". When including a sub-bpobj by reference, if the sub-bpobj itself has less than a block of sub-sub-bpobj's, the list of sub-sub-bpobj's is copied to the parent bpobj's list of sub-bpobj's.

* Fix ztest deadman panic with indirect vdev damageTom Caputi2018-10-242-4/+9
| | | | | | | | | | | | | | This patch fixes an issue where ztest's deadman thread would trigger a panic because reconstructing artifically damaged blocks would take too long to reconstruct. This patch simply limits how often ztest inflicts split-block damage and how many segments it can damage when it does.

* Fix issue with scanning dedup blocks as scan endsTom Caputi2018-10-241-0/+16
| | | | | | | | | | | | | | This patch fixes an issue discovered by ztest where dsl_scan_ddt_entry() could add I/Os to the dsl scan queues between when the scan had finished all required work and when the scan was marked as complete. This caused the scan to spin indefinitely without ending.

* Fix lock inversion in txg_sync_thread()Tom Caputi2018-10-241-2/+2
| | | | | | | | | | | | | | | This patch fixes a lock inversion issue in txg_sync_thread() where the code would attempt hold the spa config lock as a reader while holding tx->tx_sync_lock. This races with spa_vdev_remove() which attempts to hold the tx->tx_sync_lock to assign a new tx (via spa_history_log_internal()) while holding the spa config lock as a writer.

* Fix dbgmsg printing in ztest and zdbTom Caputi2018-10-245-26/+82
| | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch resolves a problem where the -G option in both zdb and ztest would cause the code to call __dprintf() to print zfs_dbgmsg output. This function was not properly wired to add messages to the dbgmsg log as it is in userspace and so the messages were simply dropped. This patch also tries to add some degree of distinction to dprintf() (which now prints directly to stdout) and zfs_dbgmsg() (which adds messages to an internal list that can be dumped with zfs_dbgmsg_print()). In addition, this patch corrects an issue where ztest used a global variable to decide whether to dump the dbgmsg buffer on a crash. This did not work because ztest spins up more instances of itself using execv(), which did not copy the global variable to the new process. The option has been moved to the ztest_shared_opts_t which already exists for interprocess communication. This patch also changes zfs_dbgmsg_print() to use write() calls instead of printf() so that it will not fail when used in a signal handler.

| | | | | | | | | | | | | The zloop test has been failing in buildbot for the last few weeks with various failures in ztest_deadman_thread(). This is due to the fact that this thread is not stopped when performing pool import / export tests as it should be. This patch simply corrects this.

* Allow use of pool GUID as root poolGeorge Melikov2018-10-231-1/+10
| | | | | | | | | | | | | It's helpful if there are pools with same names, but you need to use only one of them. Main case is twin servers, meanwhile some software requires the same name of pools (e.g. Proxmox).
