Originally we asserted that all reads are less than SPA_MAXBLOCKSIZE However, nvlists are not ZFS records, and are not limited to SPA_MAXBLOCKSIZE. Add a new environment variable, ZFS_SENDRECV_MAX_NVLIST, to allow the user to specify the maximum size of the nvlist that can be sent or received. Default value: 4 * SPA_MAXBLOCKSIZE (64 MB) Modify libzfs send routines to return a useful error if the send stream will generate an nvlist that is beyond the maximum size. Modify libzfs recv routines to add an explicit error message if the nvlist is too large, rather than abort()ing. Move the change the assert() to only trigger on data records Reviewed-by: Paul Dagnelie <pcd@delphix.com> Reviewed-by: Kjeld Schouten <kjeld@schouten-lebbing.nl> Reviewed-by: Brian Behlendorf <behlendorf1@llnl.gov> Reviewed-by: Matthew Ahrens <mahrens@delphix.com> Signed-off-by: Allan Jude <allan@klarasystems.com> Closes #9616
