-  programs to communicate with alfred (done via unix sockets). alfred then takes
-  care of distributing the local information to other alfred servers on other

-  configuration. A user can request data from alfred, and will receive the
-  information available from all alfred servers in the network.

 define Package/babeld/description
-  Babel is a loop-avoiding distance-vector routing protocol for IPv6 and IPv4
-  with fast convergence properties. It is based on the ideas in DSDV, AODV and
-  Cisco's EIGRP, but is designed to work well not only in wired networks but
-  also in wireless mesh networks, and has been extended with support for
-  overlay networks. Babel is an IETF standard protocol (RFC 8966).
+ Babel is a loop-avoiding distance-vector routing protocol roughly based
+ on DSDV and AODV, but with provisions for link cost estimation and
+ redistribution of routes from other routing protocols.
+ While it is optimised for wireless mesh networks, Babel will also work
+ efficiently on wired networks. It will generate between 1.2 and 2.4 times
+ the amount of routing traffic that RIPng would generate, while
+ never counting to infinity.

+Subject: batctl: suppress implicit-fallthrough compiler warning
+
+GCC 7.1.0 complains about an intended fallthrough.
+“__attribute__ ((fallthrough))” in this part of code would suppress this
+warning. Because older GCC compiler don’t understand this statement attribute
+and because there is already a comment in the source containing
+“falls?[ \t-]*thr(ough|u)” we can suppress the warning with the
+“-Wimplicit-fallthrough=2” warning option. Unintended fallthroughs without a
+comment would trigger this warning again.
+
+To avoid compiler recognition in the Makefile a simply change of the comment
+is sufficient to suppress the warning. For some reason only stand alone
+comments mentioned in [1] are recognized so the comment has to be split up into
+two parts.

 define KernelPackage/batman-adv/description
-  B.A.T.M.A.N. (better approach to mobile ad-hoc networking) is
-  a routing protocol for multi-hop ad-hoc mesh networks. The
-  networks may be wired or wireless. See
-  https://www.open-mesh.org/ for more information and user space
-  tools. This package builds version $(PKG_VERSION) of the kernel
-  module.
+B.A.T.M.A.N. advanced is a kernel module which allows to
+build layer 2 mesh networks. This package builds
+version $(PKG_VERSION) of the kernel module.

-Subject: Revert "batman-adv: Migrate to linux/container_of.h"
-
-The original patch requires Linux 5.16.0 or a mac80211 compat header with this
-name. But the mac80211 package is currently not providing this header and
-OpenWrt main is still using older Linux kernel versions for some targets.
-
-This reverts commit 043ae5634bdfd4c4dd8b95a22890752495080bb5.

+Subject: batman-adv: Fix double free during fragment merge error
+
+The function batadv_frag_skb_buffer was supposed not to consume the skbuff
+on errors. This was followed in the helper function
+batadv_frag_insert_packet when the skb would potentially be inserted in the
+fragment queue. But it could happen that the next helper function
+batadv_frag_merge_packets would try to merge the fragments and fail. This
+results in a kfree_skb of all the enqueued fragments (including the just
+inserted one). batadv_recv_frag_packet would detect the error in
+batadv_frag_skb_buffer and try to free the skb again.
+
+The behavior of batadv_frag_skb_buffer (and its helper
+batadv_frag_insert_packet) must therefore be changed to always consume the
+skbuff to have a common behavior and avoid the double kfree_skb.

+Trying to split and transmit a unicast packet in 16 parts will fail for

+Subject: batman-adv: decrease maximum fragment size
+
+With this patch the maximum fragment size is reduced from 1400 to 1280
+bytes.
+
+Fragmentation v2 correctly uses the smaller of 1400 and the interface
+MTU, thus generally supporting interfaces with an MTU < 1400 bytes, too.
+
+However, currently "Fragmentation v2" does not support re-fragmentation.
+Which means that once a packet is split into two packets of 1400 + x
+bytes for instance and the next hop provides an interface with an even
+smaller MTU of 1280 bytes, then the larger fragment is lost.
+
+A maximum fragment size of 1280 bytes is a safer option as this is the
+minimum MTU required by IPv6, making interfaces with an MTU < 1280
+rather exotic.
+
+Regarding performance, this should have no negative impact on unicast
+traffic: Having some more bytes in the smaller and some less in the
+larger does not change the sum of both fragments.
+
+Concerning TT, choosing 1280 bytes fragments might result in more TT
+messages than necessary when a large network is bridged into batman-adv.
+However, the TT overhead in general is marginal due to its reactive
+nature, therefore such a performance impact on TT should not be
+noticeable for a user.

+Subject: batman-adv: Keep fragments equally sized
+
+The batman-adv fragmentation packets have the design problem that they
+cannot be refragmented. This often leads to problems when networks are
+incorrectly configured and don't use a common MTU.
+
+The sender could for example fragment a 1500 byte packet to fit in a 1280
+bytes large MTU. This would create a 1280 large packet and a 284 bytes
+large packet. But the next hop is then not able to transport 1280 bytes to
+its next hop. The 1280 byte large packet will be dropped but the 284 bytes
+large packet will still be forwarded to its destination.
+
+This can partly being avoided by splitting packets more equally. In this
+example, the two 782 bytes large packets could both potentially reach its
+destination.

+Subject: batman-adv: Initialize gw sel_class via batadv_algo
+
+The gateway selection class variable is shared between different algorithm
+versions. But the interpretation of the content is algorithm specific. The
+initialization is therefore also algorithm specific.
+
+But this was implemented incorrectly and the initialization for BATMAN_V
+always overwrote the value previously written for BATMAN_IV. This could
+only be avoided when BATMAN_V was disabled during compile time.
+
+Using a special batadv_algo hook for this initialization avoids this
+problem.

+Subject: batman-adv: prevent duplication of ARP replies when DAT is used
+
+If none of the backbone gateways in a bla setup has already knowledge of
+the mac address searched for in an incoming ARP request from the backbone
+an address resolution via the DHT of DAT is started. The gateway can send
+several ARP requests to different DHT nodes and therefore can get several
+replies. This patch assures that not all of the possible ARP replies are
+returned to the backbone by checking the local DAT cache of the gateway.
+If there is an entry in the local cache the gateway has already learned
+the requested address and there is no need to forward the additional reply
+to the backbone.
+Furthermore it is checked if this gateway has claimed the source of the ARP
+reply and only forwards it to the backbone if it has claimed the source or
+if there is no claim at all.

+Subject: batman-adv: handle race condition for claims between gateways
+
+Consider the following situation which has been found in a test setup:
+Gateway B has claimed client C and gateway A has the same backbone
+network as B. C sends a broad- or multicast to B and directly after
+this packet decides to send another packet to A due to a better TQ
+value. B will forward the broad-/multicast into the backbone as it is
+the responsible gw and after that A will claim C as it has been
+chosen by C as the best gateway. If it now happens that A claims C
+before it has received the broad-/multicast forwarded by B (due to
+backbone topology or due to some delay in B when forwarding the
+packet) we get a critical situation: in the current code A will
+immediately unclaim C when receiving the multicast due to the
+roaming client scenario although the position of C has not changed
+in the mesh. If this happens the multi-/broadcast forwarded by B
+will be sent back into the mesh by A and we have looping packets
+until one of the gateways claims C again.
+In order to prevent this, unclaiming of a client due to the roaming
+client scenario is only done after a certain time is expired after
+the last claim of the client. 100 ms are used here, which should be
+slow enough for big backbones and slow gateways but fast enough not
+to break the roaming client use case.

+Subject: batman-adv: fix TT sync flag inconsistencies
+
+This patch fixes an issue in the translation table code potentially
+leading to a TT Request + Response storm. The issue may occur for nodes
+involving BLA and an inconsistent configuration of the batman-adv AP
+isolation feature. However, since the new multicast optimizations, a
+single, malformed packet may lead to a mesh-wide, persistent
+Denial-of-Service, too.
+
+The issue occurs because nodes are currently OR-ing the TT sync flags of
+all originators announcing a specific MAC address via the
+translation table. When an intermediate node now receives a TT Request
+and wants to answer this on behalf of the destination node, then this
+intermediate node now responds with an altered flag field and broken
+CRC. The next OGM of the real destination will lead to a CRC mismatch
+and triggering a TT Request and Response again.
+
+Furthermore, the OR-ing is currently never undone as long as at least
+one originator announcing the according MAC address remains, leading to
+the potential persistency of this issue.
+
+This patch fixes this issue by storing the flags used in the CRC
+calculation on a a per TT orig entry basis to be able to respond with
+the correct, original flags in an intermediate TT Response for one
+thing. And to be able to correctly unset sync flags once all nodes
+announcing a sync flag vanish for another.

+Subject: batman-adv: Avoid spurious warnings from bat_v neigh_cmp implementation
+
+The neighbor compare API implementation for B.A.T.M.A.N. V checks whether
+the neigh_ifinfo for this neighbor on a specific interface exists. A
+warning is printed when it isn't found.
+
+But it is not called inside a lock which would prevent that this
+information is lost right before batadv_neigh_ifinfo_get. It must therefore
+be expected that batadv_v_neigh_(cmp|is_sob) might not be able to get the
+requested neigh_ifinfo.
+
+A WARN_ON for such a situation seems not to be appropriate because this
+will only flood the kernel logs. The warnings must therefore be removed.

+Subject: batman-adv: Fix internal interface indices types
+
+batman-adv uses internal indices for each enabled and active interface.
+It is currently used by the B.A.T.M.A.N. IV algorithm to identifify the
+correct position in the ogm_cnt bitmaps.
+
+The type for the number of enabled interfaces (which defines the next
+interface index) was set to char. This type can be (depending on the
+architecture) either signed (limiting batman-adv to 127 active slave
+interfaces) or unsigned (limiting batman-adv to 255 active slave
+interfaces).
+
+This limit was not correctly checked when an interface was enabled and thus
+an overflow happened. This was only catched on systems with the signed char
+type when the B.A.T.M.A.N. IV code tried to resize its counter arrays with
+a negative size.
+
+The if_num interface index was only a s16 and therefore significantly
+smaller than the ifindex (int) used by the code net code.
+
+Both &batadv_hard_iface->if_num and &batadv_priv->num_ifaces must be
+(unsigned) int to support the same number of slave interfaces as the net
+core code. And the interface activation code must check the number of
+active slave interfaces to avoid integer overflows.

+Subject: batman-adv: Fix multicast packet loss with a single WANT_ALL_IPV4/6 flag
+
+As the kernel doc describes too the code is supposed to skip adding
+multicast TT entries if both the WANT_ALL_IPV4 and WANT_ALL_IPV6 flags
+are present.
+
+Unfortunately, the current code even skips adding multicast TT entries
+if only either the WANT_ALL_IPV4 or WANT_ALL_IPV6 is present.
+
+This could lead to IPv6 multicast packet loss if only an IGMP but not an
+MLD querier is present for instance or vice versa.

+Subject: batman-adv: fix packet loss for broadcasted DHCP packets to a server
+
+DHCP connectivity issues can currently occur if the following conditions
+are met:
+
+1) A DHCP packet from a client to a server
+2) This packet has a multicast destination
+3) This destination has a matching entry in the translation table
+   (FF:FF:FF:FF:FF:FF for IPv4, 33:33:00:01:00:02/33:33:00:01:00:03
+    for IPv6)
+4) The orig-node determined by TT for the multicast destination
+   does not match the orig-node determined by best-gateway-selection
+
+In this case the DHCP packet will be dropped.
+
+The "gateway-out-of-range" check is supposed to only be applied to
+unicasted DHCP packets to a specific DHCP server.
+
+In that case dropping the the unicasted frame forces the client to
+retry via a broadcasted one, but now directed to the new best
+gateway.
+
+A DHCP packet with broadcast/multicast destination is already ensured to
+always be delivered to the best gateway. Dropping a multicasted
+DHCP packet here will only prevent completing DHCP as there is no
+other fallback.
+
+So far, it seems the unicast check was implicitly performed by
+expecting the batadv_transtable_search() to return NULL for multicast
+destinations. However, a multicast address could have always ended up in
+the translation table and in fact is now common.
+
+To fix this potential loss of a DHCP client-to-server packet to a
+multicast address this patch adds an explicit multicast destination
+check to reliably bail out of the gateway-out-of-range check for such
+destinations.
+
+The issue and fix were tested in the following three node setup:
+
+- Line topology, A-B-C
+- A: gateway client, DHCP client
+- B: gateway server, hop-penalty increased: 30->60, DHCP server
+- C: gateway server, code modifications to announce FF:FF:FF:FF:FF:FF
+
+Without this patch, A would never transmit its DHCP Discover packet
+due to an always "out-of-range" condition. With this patch,
+a full DHCP handshake between A and B was possible again.

+Subject: batman-adv: Avoid race in TT TVLV allocator helper
+
+The functions batadv_tt_prepare_tvlv_local_data and
+batadv_tt_prepare_tvlv_global_data are responsible for preparing a buffer
+which can be used to store the TVLV container for TT and add the VLAN
+information to it.
+
+This will be done in three phases:
+
+1. count the number of VLANs and their entries
+2. allocate the buffer using the counters from the previous step and limits
+   from the caller (parameter tt_len)
+3. insert the VLAN information to the buffer
+
+The step 1 and 3 operate on a list which contains the VLANs. The access to
+these lists must be protected with an appropriate lock or otherwise they
+might operate on on different entries. This could for example happen when
+another context is adding VLAN entries to this list.
+
+This could lead to a buffer overflow in these functions when enough entries
+were added between step 1 and 3 to the VLAN lists that the buffer room for
+the entries (*tt_change) is smaller then the now required extra buffer for
+new VLAN entries.

+Subject: batman-adv: Fix TT sync flags for intermediate TT responses
+
+The previous TT sync fix so far only fixed TT responses issued by the
+target node directly. So far, TT responses issued by intermediate nodes
+still lead to the wrong flags being added, leading to CRC mismatches.
+
+This behaviour was observed at Freifunk Hannover in a 800 nodes setup
+where a considerable amount of nodes were still infected with 'WI'
+TT flags even with (most) nodes having the previous TT sync fix applied.
+
+I was able to reproduce the issue with intermediate TT responses in a
+four node test setup and this patch fixes this issue by ensuring to
+use the per originator instead of the summarized, OR'd ones.

+Subject: batman-adv: prevent TT request storms by not sending inconsistent TT TLVLs
+
+A translation table TVLV changset sent with an OGM consists
+of a number of headers (one per VLAN) plus the changeset
+itself (addition and/or deletion of entries).
+
+The per-VLAN headers are used by OGM recipients for consistency
+checks. Said consistency check might determine that a full
+translation table request is needed to restore consistency. If
+the TT sender adds per-VLAN headers of empty VLANs into the OGM,
+recipients are led to believe to have reached an inconsistent
+state and thus request a full table update. The full table does
+not contain empty VLANs (due to missing entries) the cycle
+restarts when the next OGM is issued.
+
+Consequently, when the translation table TVLV headers are
+composed, empty VLANs are to be excluded.
+

+Subject: batman-adv: Fix debugfs path for renamed hardif

+batman-adv is creating special debugfs directories in the init

+possible to rename a net_device to a completely different name then the
+original one.
+
+It can therefore happen that a user registers a new net_device which gets
+the name "wlan0" assigned by default. batman-adv is also adding a new
+directory under $debugfs/batman-adv/ with the name "wlan0".
+
+The user then decides to rename this device to "wl_pri" and registers a
+different device. The kernel may now decide to use the name "wlan0" again
+for this new device. batman-adv will detect it as a valid net_device and
+tries to create a directory with the name "wlan0" under
+$debugfs/batman-adv/. But there already exists one with this name under
+this path and thus this fails. batman-adv will detect a problem and
+rollback the registering of this device.
+
+batman-adv must therefore take care of renaming the debugfs directories
+for hard-interfaces whenever it detects such a net_device rename.

+Subject: batman-adv: Avoid storing non-TT-sync flags on singular entries too
+
+Since commit 382d020fe3fa ("batman-adv: fix TT sync flag inconsistencies")
+TT sync flags and TT non-sync'd flags are supposed to be stored
+separately.
+
+The previous patch missed to apply this separation on a TT entry with
+only a single TT orig entry.
+
+This is a minor fix because with only a single TT orig entry the DDoS
+issue the former patch solves does not apply.

+Subject: batman-adv: Fix multicast TT issues with bogus ROAM flags
+
+When a (broken) node wrongly sends multicast TT entries with a ROAM
+flag then this causes any receiving node to drop all entries for the
+same multicast MAC address announced by other nodes, leading to
+packet loss.
+
+Fix this DoS vector by only storing TT sync flags. For multicast TT
+non-sync'ing flag bits like ROAM are unused so far anyway.

+Subject: batman-adv: Avoid probe ELP information leak
+
+The probe ELPs for WiFi interfaces are expanded to contain at least
+BATADV_ELP_MIN_PROBE_SIZE bytes. This is usually a lot more than the
+number of bytes which the template ELP packet requires.
+
+These extra padding bytes were not initialized and thus could contain data
+which were previously stored at the same location. It is therefore required
+to set it to some predefined or random values to avoid leaking private
+information from the system transmitting these kind of packets.

+The per hardif sysfs file "batman_adv/throughput_override" prints the

+
+The function batadv_info requires as first parameter the batman-adv softif

+batadv_store_throughput_override used as first argument the slave
+net_device. This slave device doesn't have the batadv_priv private data
+which is access by batadv_info.
+
+Writing to this file with CONFIG_BATMAN_ADV_DEBUG enabled can either lead
