Implement the conv=fsync feature which does an fsync(2) after the

final write to output. GNU dd also has this. It is useful for write performance measurement or guaranteed writes to reliable storage. OK kn@ tedu@ deraadt@

Free operand copies after parsing.

2018-07-25T15:09:48Z

We strdup operands before destructively parsing them to keep w(1) output looking nice and neat, but after parsing we ought to free them. We do need to keep copies for file paths, though, so add additional strdups for operands if and of. While here, use the preferred err(1, NULL) for an allocation failure. Also while here, don't assign `oper' to a copy of itself because it looks strange. "sure." deraadt

from erroring out with "dd: skip: Undefined error: 0", mostly for consistency and to avoid the unidiomatic, wrong looking code. Patch from Bulat Musin . OK guenther@ millert@

Error out when negative values are given for sizes on the command line.

Do not error out when the maximum permissible value is given, but only when it is exceeded. Patch from William Orr using feedback from tedu@. ok millert@

The "old" conversions are not mandated by any standard and are

Add an operand to /bin/dd that suppresses the status lines printed

to stderr after transfer. Use the GNU syntax status=noxfer and status=none to make dd quiet. The output is annoying in some situations, so people redirect stderr to /dev/null. This approach also suppresses the error messages and bugs in shell scripts remain undetected. The new feature status=none is the better alternative. OK mpf@
