Log: MFC r298483, r298744, r299085, r299087, and r300747 to usr.sbin/extattr r300747 | asomers | 2016-05-26 08:26:49 -0600 (Thu, 26 May 2016) | 8 lines rmextattr(8) man page clarifications regarding -qq r299087 | asomers | 2016-05-04 15:07:30 -0600 (Wed, 04 May 2016) | 13 lines Fix "getextattr -x" with non-ascii attribute values extattr/rmextattr.c When printing hex output, treat all attribute values as unsigned char arrays instead of sign extending them to 32 bit values. extattr/tests/extattr_test.sh Add a regression test r299085 | asomers | 2016-05-04 14:20:55 -0600 (Wed, 04 May 2016) | 30 lines Allow setextattr(8) to take attribute values from stdin Add the -i option to setextattr. This option allow extended attribute data to be provided via stdin. Add a -qq option to getextattr, which omits the trailing newline. Together these options can be used to work with extended attributes whose values are large and/or binary. usr.sbin/extattr/Makefile: Link against libsbuf which is used for processing stdin data. usr.sbin/extattr/rmextattr.8: Document setextattr's -i option, getextattr's -qq option, and remove the BUG about setextattr only being useful for strings. usr.sbin/extattr/rmextattr.c: For setextattr operations, buffer attribute data in an sbuf. If -i is specified, pull the data from stdin, otherwise from the appropriate argurment. Update usage text and argument validation code for setextattr's -i option. usr.sbin/extattr/tests/extattr_test.sh Add tests for -q and -i. r298744 | asomers | 2016-04-28 09:13:50 -0600 (Thu, 28 Apr 2016) | 11 lines Add PACKAGE fields to usr.sbin/extattr/tests/Makefile usr.sbin/extattr/tests/Makefile Add boiler plate required by 298107 but omitted by 298483. These two changes passed through CR in parallel. I think this should get the full test suite running in Jenkins again. r298483 | asomers | 2016-04-22 11:02:47 -0600 (Fri, 22 Apr 2016) | 10 lines Add ATF tests for usr.sbin/extattr Add ATF tests for the existing behavior of setextattr, rmextattr, lsextattr, and getextattr.
