Make the 'zpool import' command honor the overlay property to allow filesystems to be mounted on a non-empty directory. As it stands now this property is only checked by the 'zfs mount' command. Move the check into 'zfs_mount()` in libzpool so the property is honored for all callers. Signed-off-by: Ned Bass <bass6@llnl.gov> Signed-off-by: Brian Behlendorf <behlendorf1@llnl.gov> Closes #3227
When using 'zpool import' to scan for available pools prefer vdev names which reference vdevs with more valid labels. There should be two labels at the start of the device and two labels at the end of the device. If labels are missing then the device has been damaged or is in some other way incomplete. Preferring names with fully intact labels helps weed out bad paths and improves the likelihood of being able to import the pool. This behavior only applies when scanning /dev/ for valid pools. If a cache file exists the pools described by the cache file will be used.

When _zed_event_add_var() was updated to be the common routine for adding zedlet environment variables, an additional snprintf() was added to the processing of each nvpair. This commit changes _zed_event_add_nvpair() to directly call _zed_event_add_var() for nvpair non-array types, thereby removing a superfluous call to snprintf(). For consistency, the helper functions for converting nvpair array types are similarly adjusted to add variables. The _zed_event_value_is_hex() and _zed_event_add_var() functions have been moved up in the file since forward declarations are not used, but no changes have been made to these functions.

The zed_strings container stores strings in an AVL, but does not check for duplicate strings being added. Within the AVL, strings are indexed by the string value itself. avl_add() requires the node being added must not already exist in the tree, and will assert() if this is not the case. This should not cause problems in practice. ZED uses this container in two places. In zed_conf.c, it is used to store the names of enabled zedlets as zed scans the zedlet directory listing; duplicate entries cannot occur here since duplicate names cannot occur within a directory. In zed_event.c, it is used to store the environment variables (as "NAME=VALUE" strings) that will be passed to zedlets; duplicate strings here should never happen unless there is a bug resulting in a duplicate nvpair or environment variable. This commit protects against adding a duplicate to a zed_strings container by first checking for the string being added, and removing the previous entry should one exist. This implements a "last one wins" policy. This commit also changes the prototype for zed_strings_add() to allow the string key (by which it is indexed in the AVL) to differ from the string value. By adding zedlet environment variables using the variable name as the key, multiple adds for the same variable name will result in only the last value being stored. Finally, this commit routes all additions of zedlet environment variables through the updated _zed_event_add_var(). This ensures all zedlet environment variable names are properly converted.
