* batman-adv: Fix lock assert after fragmentation changeSven Eckelmann2023-08-221-0/+35
| | | | | | | | | | | | | | | | The automatic recalculation of the maximum allowed MTU is usually triggered by code sections which are already rtnl lock protected by callers outside of batman-adv. But when the fragmentation setting is changed via batman-adv's own batadv genl family, then the rtnl lock is not yet taken. But dev_set_mtu requires that the caller holds the rtnl lock because it uses netdevice notifiers. And this code will then fail the check for this lock: RTNL: assertion failed at net/core/dev.c (1953) Fixes: 12577be7ed67 ("batman-adv: Merge bugfixes from 2023.2") Signed-off-by: Sven Eckelmann <sven@narfation.org>

* batman-adv: compat: Add atomic mc_forwarding support for stable kernelsSven Eckelmann2022-04-172-0/+50
| | | | | | | | | | | | | | | Eric Dumazet changed the mc_forwarding in commit 145c7a793838 ("ipv6: make mc_forwarding atomic") the type of mc_forwarding from __s32 to an atomic_t. This patch was then ported to various stable kernels. This code change caused a FTBFS when in batman-adv when CONFIG_BATMAN_ADV_MCAST was activated. To work around this problem, provide a version for kernels with __s32 mc_forwarding and a version for kernel with atomic_t mc_forwarding.

* | batman-adv: Prevent use from libc headers to not build with BIG_ENDIANHendrik Borghorst2021-11-271-0/+1
|/ | | | | | | | | | | | | | Commit 97d35a552ec5b6ddf7923dd2f9a8eb973526acea of musl introduced the macros __LITTLE_ENDIAN and __BIG_ENDIAN in alltypes.h. These are pulled into the compilation of batman-adv. This has the side effect that the function is_multicast_ether_addr of etherdevice.h in Linux kernel is compiled as the big endian version and so fails to work properly on little endian devices. This commits prevents pulling in header files of musl libc similar to OpenWRT commit 9ac47ee46918c45b91f4e4d1fa76b1e26b9d57fe Signed-off-by: Hendrik Borghorst <hendrikborghorst@gmail.com>

* batman-adv: Always send iface index+name in genlmsgSven Eckelmann2021-05-181-0/+117
| | | | | | | | | | | | | | | | | | | | | | The batman-adv netlink messages often contain the interface index and interface name in the same message. This makes it easy for the receiver to operate on the incoming data when it either needs to print something or needs to operate on the interface index. But one of the attributes was missing for: * neighbor table dumps * originator table dumps * gateway list dumps * query of hardif information * query of vid information The userspace therefore had to implement special workarounds using SIOCGIFNAME or SIOCGIFINDEX depending on what was actually provided. Providing both information simplifies the userspace code massively without adding a lot of extra overhead in the kernel portion. Signed-off-by: Sven Eckelmann <sven@narfation.org>

* batman-adv: Fix duplicated OGMs on NETDEV_UPSven Eckelmann2019-06-022-1/+78
| | | | | | | | | | | | | | | | | | | | | The state of slave interfaces are handled differently depending on whether the interface is up or not. All active interfaces (IFF_UP) will transmit OGMs. But for B.A.T.M.A.N. IV, also non-active interfaces are scheduling (low TTL) OGMs on active interfaces. The code which setups and schedules the OGMs must therefore already be called when the interfaces gets added as slave interface and the transmit function must then check whether it has to send out the OGM or not on the specific slave interface. But v2016.3 moved the setup code from the enable function to the activate function. The latter is called either when the added slave was already up when batadv_hardif_enable_interface processed the new interface or when a NETDEV_UP event was received for this slave interfac. As result, each NETDEV_UP would schedule a new OGM worker for the interface and thus OGMs would be send a lot more than expected.

* batman-adv: Split batadv proto in meshif and hardif partSven Eckelmann2019-03-077-117/+235
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | batman-adv allows to configure three different objects: * batadv hardif - network interface used by batadv meshif to transport the batman-adv packets - its master interface is set to the batadv meshif * batadv (meshif/softif) - virtual interface that emulates a normal 802.3 interface on top - encapsulates traffic and forwards it via the batadv hardifs * batadv vlan - potential VLAN ID on top of batadv meshif - allows filtering of traffic from specific VIDs While batadv vlan objects were already represented as an own proto "batadv_vlan", the batadv meshif could never be fully configured using /etc/config/network. Instead, parts of its configuration were stored in /etc/config/batman_adv and some in the interfaces with the "batadv" proto. To increase the confusion, the "batadv" proto wasn't used to define the batadv meshif but to identify batadv (slave) hardifs. The batman-adv meshifs were also never created directly but only when a hardif was configured. The actual modification of the configuration settings was then applied using a hotplug script hack. The batadv meshif network interface could therefore only be created when an hardif was available and not manipulated with ifup/ifdown. Also `/etc/init.d/network reload` didn't modify the batadv meshif interface configuration correctly. The "batadv" is now renamed to "batadv_hardif" and a new "batadv" proto is used to configure the main (meshif) network interface with all its configuration. A simple network configuration with WiFi & ethernet interfaces and static IP on top of bat0 would look like: # batadv meshif bat0 config interface 'bat0' option proto 'batadv' option routing_algo 'BATMAN_IV' option aggregated_ogms 1 option ap_isolation 0 option bonding 0 option fragmentation 1 #option gw_bandwidth '10000/2000' option gw_mode 'off' #option gw_sel_class 20 option log_level 0 option orig_interval 1000 option bridge_loop_avoidance 1 option distributed_arp_table 1 option multicast_mode 1 option network_coding 0 option hop_penalty 30 option isolation_mark '0x00000000/0x00000000' # add *single* wifi-iface with network bat0_hardif_wlan as hardif to bat0 config interface 'bat0_hardif_wlan' option mtu '1536' option proto 'batadv_hardif' option master 'bat0' # option ifname is filled out by the wifi-iface # add eth0 as hardif to bat0 config interface 'bat0_hardif_eth0' option proto 'batadv_hardif' option master 'bat0' option ifname 'eth0' option mtu '1536' # configure IP on bat0 config interface 'bat0_lan' option ifname 'bat0' option proto 'static' option ipaddr '192.168.1.1' option netmask '255.255.255.0' option ip6assign '60' Signed-off-by: Sven Eckelmann <sven@narfation.org>
