babeld: Update babeld to 1.9.2
babeld is updated to 1.9.2 using a feed patch. The new version includes fixes a few minor issues. With babeld 1.9.2 a fix for IPv4 xroutes has been introduced. Therefore, our own patch isn't necessary anymore, so it is removed. Signed-off-by: Fabian Bläse <fabian@blaese.de> Reviewed-by: Adrian Schmutzler <freifunk@adrianschmutzler.de>

+Subject: [PATCH] Remove src_plen assignments which break v4mapped encoding
|
||||
+MIME-Version: 1.0
|
||||
+Content-Type: text/plain; charset=UTF-8
|
||||
+Content-Transfer-Encoding: 8bit
|
||||
+
|
||||
+These assignments were introduced in f8bce04, probably
|
||||
+to ensure that src_plen doesn't contain any leftovers from
|
||||
+earlier revisions when source specific wasn't done via sub-TLVs.
|
||||
+
|
||||
+This however breaks v4mapped encoding as a prefix length of 0
|
||||
+for IPv4 routes is represented as src_plen = 96. This offset is
|
||||
+already added outside of the affected functions and therefore
|
||||
+gets overwritten by this assignment.
|
||||
+
|
||||
+Both functions contain an additional check if the message contains
|
||||
+ipv4 addresses, but as this check is only executed if the message has
|
||||
+a source-specific sub-TLV, the offset isn't added for non source-specific
|
||||
+routes.
|
||||
+
|
||||
+Because the offset is already added outside of the subtlv parsing
|
||||
+functions, this additional check is also removed, as it would otherwise
|
||||
+break IPv4 source specifics by adding the IPv4 offset two times.

Fabian Bläse.
