Bisecting identified the redacted send/receive as the source of the bug for issue #12014. Specifically the call to dsl_dataset_hold_obj(&fromds) has been replaced by dsl_dataset_hold_obj_flags() which passes a DECRYPT flag and creates a key mapping. A subsequent dsl_dataset_rele_flag(&fromds) is missing and the key mapping is not cleared. This may be inadvertedly used, which results in arc_untransform failing with ECKSUM in: arc_untransform+0x96/0xb0 [zfs] dbuf_read_verify_dnode_crypt+0x196/0x350 [zfs] dbuf_read+0x56/0x770 [zfs] dmu_buf_hold_by_dnode+0x4a/0x80 [zfs] zap_lockdir+0x87/0xf0 [zfs] zap_lookup_norm+0x5c/0xd0 [zfs] zap_lookup+0x16/0x20 [zfs] zfs_get_zplprop+0x8d/0x1d0 [zfs] setup_featureflags+0x267/0x2e0 [zfs] dmu_send_impl+0xe7/0xcb0 [zfs] dmu_send_obj+0x265/0x360 [zfs] zfs_ioc_send+0x10c/0x280 [zfs] Fix this by restoring the call to dsl_dataset_hold_obj(). The same applies for to_ds: here replace dsl_dataset_rele(&to_ds) with dsl_dataset_rele_flags(). Both leaked key mappings will cause a panic when exporting the sending pool or unloading the zfs module after a non-raw send from an encrypted filesystem.
