Remi Pommarel 0d2fbae5f5 batman-adv: Remove uninitialized data in full table TT response
[ Upstream commit 8038806db64da15721775d6b834990cacbfcf0b2 ]

The number of entries filled by batadv_tt_tvlv_generate() can be less
than initially expected in batadv_tt_prepare_tvlv_{global,local}_data()
(changes can be removed by batadv_tt_local_event() in ADD+DEL sequence
in the meantime as the lock held during the whole tvlv global/local data
generation).

Thus tvlv_len could be bigger than the actual TT entry size that need
to be sent so full table TT_RESPONSE could hold invalid TT entries such
as below.

 * 00:00:00:00:00:00   -1 [....] (  0) 88:12:4e:ad:7e:ba (179) (0x45845380)
 * 00:00:00:00:78:79 4092 [.W..] (  0) 88:12:4e:ad:7e:3c (145) (0x8ebadb8b)

Remove the extra allocated space to avoid sending uninitialized entries
for full table TT_RESPONSE in both batadv_send_other_tt_response() and
batadv_send_my_tt_response().

README

Linux kernel
============

There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.

In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``.  The formatted documentation can also be read online at:

    https://www.kernel.org/doc/html/latest/

There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.

Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
