7 years agoperl plugin: Fix potential double-free.
Florian Forster [Sun, 14 May 2017 06:24:51 +0000 (08:24 +0200)]
perl plugin: Fix potential double-free.

The av2notification_meta() function updated it's parameter by doing

    (*m) = malloc();

Afterwards, if an error occurred, it would call `free(*m);` and (potentially)
return, leaving an invalid pointer stored in `m`. The caller would then try to
free the returned pointer because it was non-NULL.

This patch fixes this by doing several code cleanups:

*   The meta argument is not updated unnecessarily. Instead, a local variable
    is allocated and used within the loop and only on success is the return
    pointer updated.
*   Introduce additional local variables instead of re-using the `tmp` variable
    multiple times.
*   Name the variable pointing to the end of the linked list appropriately
    `tail` and remove one level of indirection. Reading code that is using
    pointers to pointers is unnecessarily hard.

bind plugin: Use timegm() to convert to time_t if available.

FreeBSD doesn't provide the "extern long timezone", presumably because
it's "only" an XSI extension, leading to a portability issue with the
previous approach.

timegm() is a non-standard function available in GNU's and BSD's libc
which is doing exactly what we need. The previous code is left as a
fallback.

common.c: Use _LINUX_CAPABILITY_VERSION_3 in cap_header

While check_capability() function already requires
_LINUX_CAPABILITY_VERSION_3 via "#ifdef" since commit 448627953c we still
set the cap_header's version to deprecated _LINUX_CAPABILITY_VERSION. This
results in a warning like

 > capability: warning: `collectd' uses 32-bit capabilities (legacy support in use)

from the kernel when a plugin (like iptables) calls our check_capability()
function.

With this commit we will set cap_header to kernel's current capability
version (_LINUX_CAPABILITY_VERSION_3), which is default since
kernel 2.6.26.

curl_json plugin: Skip unexpected non-map values.

Assume, for example, the config `Key "*/foo"`. This config expects JSON
in the form:

    {
      "bar": {
        "foo": 1337
      }
    }

If the available JSON is instead:

    {
      "error_code": 0,
      "bar": {
        "foo": 1337
      }
    }

the code will take a look at the zero associated with "error_code" and
determine that a map (with key "foo") is expected instead. Previously
the code would continue, eventually calling `cj_get_type()` which
expects that `key->type` is a valid pointer, resulting in a segmentation
fault.

This patch does three things to ensure that this segmentation fault does
not happen again:

1.  `cj_get_type()` checks its argument to make sure it is valid before
    dereferencing any pointers.
2.  In case a non-map is found when a map is expected, the code will
    return instead of limping on.
3.  After calling `cj_cb_inc_array_index()`, which may update the key,
    make sure that it actually did and that key is valid now.
