sg3_utils version/release 1.48

Summary Changelog for release sg3_utils-1.48 [20230801] [svn: r1042]

New utilities:

sg_rem_rest_elem: removing or restoring physical elements
sg_rep_density: decode report density response (tape)
sg_sat_datetime: accessing  date/time (S)ATA commands
sg_write_attr: for write attribute command (tape)
sg_z_act_query: for zone activate or zone query command

JSON support:

utilities in this package that decode a significant amount of
metadata (as defined by T10) now have optional JSON output. The
default remains plain text output. The long forms of the new JSON
options are --json[=JO] and -js-file=JFN where the (optional) 'JO'
is a sequence of JSON one letter options. 'JFN' is a filename into
which the JSON output will be sent; otherwise JSON output goes to
stdout. The utilities with JSON support are:
sg_decode_sense, sg_get_elem_status, sg_get_lba_status, sg_inq,
sg_logs, sg_luns, sg_opcodes, sg_readcap, sg_rep_zones, sg_ses,
sg_vpd .
Snake notation is used for JSON names, similar to sysfs file naming
conventions (e.g. 'vpd_pg83'). T10 command, page and field names
are all converted to snake notation when they appear in a JSON name.

BUILD changes:

All the intermediate build files like configure and Makefile.in
have been removed. This reduces the size of the source package
in subversion and git. The downside is that an extra step is
required at the start of the build process. The canonical form
is now './autogen.sh ; ./configure ; make ; make install' .
There is also a 'bootstrap' script that simply calls autogen.sh .
The official tarballs will contain the intermediate files for
compatibility with older versions.

Others changes:

• netbsd: experimental port, scsi only
• rescan-scsi-bus.sh: lots of fixes and speed ups
• track additions in recent drafts of SPC-5, SPC-6 and SBC-5
• expansion of support for the --inhex=HFN option. HFN is a
  filename assumed to contain hex representing the response to
  one or more SCSI commands. The new 'inhex' directory contains
  files of hex data for many utilities in this package.
  Invocation examples are included as comments in those files.
  For example inhex/get_lba_status.hex is response data for
  the sg_get_lba_status utility.
