* dd: Incorporate some changes from imp for status=progressKyle Evans2018-08-151-0/+2
| | | | | | | | | | | | | | | Notable changes from what landed in r337505: - sigalarm handler isn't setup unless we're actually using it - Humanized versions of the amount of data transferred in the progress update Submitted by: imp Reviewed by: kevans MFC after: 1 week Differential Revision: https://reviews.freebsd.org/D16642 Notes: svn path=/head/; revision=337865
* General further adoption of SPDX licensing ID tags.Pedro F. Giffuni2017-11-201-0/+2
| | | | | | | | | | | | | | | | | Mainly focus on files that use BSD 3-Clause license. The Software Package Data Exchange (SPDX) group provides a specification to make it easier for automated tools to detect and summarize well known opensource licenses. We are gradually adopting the specification, noting that the tags are considered only advisory and do not, in any way, superceed or replace the license texts. Special thanks to Wind River for providing access to "The Duke of Highlander" tool: an older (2014) run over FreeBSD tree was useful as a starting point. Notes: svn path=/head/; revision=326025
* dd(1): Incorrect casting of argumentsAlan Somers2017-08-251-1/+1
| | | | | | | | | | | | | | | dd(1) casts many of its numeric arguments from uintmax_t to intmax_t and back again to detect whether or not the original arguments were negative. This is not correct, and causes problems with boundary cases, for example when count is SSIZE_MAX-1.

* Fix integer overflow detection in ddAlan Somers2017-05-311-1/+1
| | | | | | | | | | | | | | | dd(1) tried to detect whether the seek offset would overflow, but it failed to account for the case where the provided argument was negative and the file was a regular file (negative seeks are allowed for character devices). I fixed it, and added a regression test. Reported by: Coverity CID: 1368659 MFC after: 3 weeks Sponsored by: Spectra Logic Corp Notes: svn path=/head/; revision=319339
* Renumber copyright clause 4Warner Losh2017-02-281-1/+1
| | | | | | | | | | | | Renumber cluase 4 to 3, per what everybody else did when BSD granted them permission to remove clause 3. My insistance on keeping the same numbering for legal reasons is too pedantic, so give up on that point.

* dd(1): Enable access to SIZE_T_MAX character devicesConrad Meyer2016-07-091-2/+31
| | | | | | | | | | | On machines where SIZE_T_MAX exceeds OFF_MAX (signed 64-bit), permit seeking character devices to negative off_t values. This enables dd(1) to interact with kernel KVA in /dev/kmem on amd64, for example. Sponsored by: EMC / Isilon Storage Division Notes: svn path=/head/; revision=302500

* Even more cleanups to dd(1). This is probably the culmination of theBrian Feldman1999-09-121-8/+6
| | | | | | | | | | | | | | | | BDEification process of dd(1). Most of the changes are from BDE's archive. Support for negative offsets is gone again, but the case where you lseek() onto byte -1 of something from a negative offset using seek/skip is fixed; if you end up on -1, you won't get a false positive lseek failure. The biggest changes are to data types (more size_t, for instance) and argument parsing. skip/seek on /dev/{,k}mem now occurs (instead of "read until you reach the offset") due to mem devices now being D_DISK. Some const things are now correctly declared as such, and the "case table" building is better. The only thing that seems to be left to make dd(1) everything TOG wants it to be is l10n.
