Because resuming from a token requires "guid" -> "snapshot" mapping we have to walk the whole dataset hierarchy to find the right snapshot to send; when both source and destination exists, for an incremental resumable stream, libzfs gets confused and picks up the wrong snapshot to send from: this results in attempting to send "destination@snap1 -> source@snap2" instead of "source@snap1 -> source@snap2" which fails with a "Invalid cross-device link" error (EXDEV). Fix this by adjusting the logic behind dataset traversal in zfs_iter_children() to pick the right snapshot to send from. Additionally update dry-run 'zfs send -t' to print its output to stderr: this is consistent with other dry-run commands.

# Description:
|
|
# Verify resumability of full and incremental ZFS send/receive with the -c
|
|
# (compress) flag in the presence of a corrupted stream.
|
|
#
|
|
# Strategy:
|
|
# 1. Start a full ZFS send with the -c flag (compress), redirect output to
|
|
# a file
|
|
# 2. Mess up the contents of the stream state file on disk
|
|
# 3. Try ZFS receive, which should fail with a checksum mismatch error
|
|
# 4. ZFS send to the stream state file again using the receive_resume_token
|
|
# 5. ZFS receieve and verify the receive completes successfully
|
|
# 6. Repeat steps on an incremental ZFS send
|
