Under C99, Sec 6.2.4, paragraph 2:
The value of a pointer becomes indeterminate when the object it
points to reaches the end of its lifetime.
`Indeterminate' (3.17.2) includes a trap representation, and any
reference to a trap representation is undefined behaviour. Thus,
after realloc(res, ...) succeeds, any reference to res (or p) is
undefined behaviour.
So, instead of using `p - res` after res has been freed, use the
existing name for the value we know it has now: len. (We could also
use alloced because p == end in this branch, and end = res + alloced,
and p = res + len. Of course, we would have to move it up a line to
before we update alloced to have a different value.)
fix https://github.com/heimdal/heimdal/issues/1164
- Add an import command that imports JSON as output by
`ktutil list --json --keys`.
This is enables one to filter/edit keytabs with jq!
- Add a `merge` alias for the `copy` command, since that's effectively
what it does.
- Add a `--copy-duplicates` option to the `copy`/`merge` command.
- Add a `--no-create` option to the `get` command.
- Add a `--no-change-keys` option to the `get` command.
- Make `add` complain if it can't finish writing to the keytab.
