* diff: fix incorrectly displaying files as duplicatesJamie Landeg-Jones2021-01-253-0/+8
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | When diff hits certain access errors, function diffreg() shows the error message, and then returns to the calling function, which calls print_status() with the return value. However, in these cases, the return value isn't changed from the initial default value of D_SAME. Normally, print_status() with a value of D_SAME does nothing, so this works out ok, however, if the "-s" flag is set, a message is displayed showing identicality: case D_SAME: if (sflag) printf("Files %s%s and %s%s are identical\n", path1, entry, path2, entry); break; This then produces such results as: % diff -s /COPYRIGHT /var/run/rpcbind.sock diff: /var/run/rpcbind.sock: Operation not supported Files /COPYRIGHT and /var/run/rpcbind.sock are identical % diff -s /COPYRIGHT /etc/master.passwd diff: /etc/master.passwd: Permission denied Files /COPYRIGHT and /etc/master.passwd are identical Create a D_ERROR status which is returned in such cases, and print_status() then deals with that status seperately from D_SAME PR: 252614 MFC after: 1 week

* elfctl: prefix disable flags with "no"Ed Maste2021-01-141-4/+5
| | | | | | | | | | | | | | Some ELF feature flags indicate a request to opt-out of some feature, for example NT_FREEBSD_FCTL_ASLR_DISABLE indicates that ASLR should be disabled for the tagged binary. Using "aslr" as the short name for the flag is confusing as it seems to indicate a request for ASLR to be enabled. Rename "noaslr", and make a similar change for other opt-out flags.

Note that using -z with differing skip values will currently always fail. We may want to compare size1 - skip1 with size2 - skip2 instaead, and in any case the man page should be clarified.

* | du: tests: fix the H_flag test (primarily grep usage)Kyle Evans2021-01-071-3/+4
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This test attempts to use \t (tab intended) in a grep expression. With the former /usr/bin/grep (i.e. gnugrep), this was interpreted as a literal 't'. The expression would work anyways because the tr(1) usage would ultimately replace all of the spaces with a single newline, and they would match the paths whether they were correctly fromatted or not. Current /usr/bin/grep (i.e. bsdgrep) is less-tolerant of ordinary-escapes, a property of the underlying regex(3) engine, to make it easier to identify when stuff like this happens. In-fact, this expression broke after the switch happened. This revision does the bare basics to fix the usage by using a printf to get a literal tab character to insert into the expression. It also swaps out the manual insertion of the line prefix into the grep expression by pulling that part out of $sep and reusing it for the leading path. The secondary issue was the tr(1) usage, since tr would only replace the first character of string1 with the first character of string2. This has instead been replaced by a sed expression, which similary understands \n to be a newline on all supported versions of FreeBSD. Each path now gets prefixed with the appropriate context that should be there (i.e. numeric sequence followed by a tab).
