batman-adv/patches/0013-batman-adv-Broken-sync-while-rescheduling-delayed-wo.patch

+From: Vladislav Efanov <VEfanov@ispras.ru>
+Date: Fri, 26 May 2023 19:16:32 +0300
+Subject: batman-adv: Broken sync while rescheduling delayed work
+
+Syzkaller got a lot of crashes like:
+KASAN: use-after-free Write in *_timers*
+
+All of these crashes point to the same memory area:
+
+The buggy address belongs to the object at ffff88801f870000
+ which belongs to the cache kmalloc-8k of size 8192
+The buggy address is located 5320 bytes inside of
+ 8192-byte region [ffff88801f870000, ffff88801f872000)
+
+This area belongs to :
+        batadv_priv->batadv_priv_dat->delayed_work->timer_list
+
+The reason for these issues is the lack of synchronization. Delayed
+work (batadv_dat_purge) schedules new timer/work while the device
+is being deleted. As the result new timer/delayed work is set after
+cancel_delayed_work_sync() was called. So after the device is freed
+the timer list contains pointer to already freed memory.
+
+Found by Linux Verification Center (linuxtesting.org) with syzkaller.

batman-adv/patches/0015-batman-adv-Do-not-get-eth-header-before-batadv_check.patch

+Date: Fri, 28 Jul 2023 15:38:50 +0200
+Subject: batman-adv: Do not get eth header before batadv_check_management_packet
+
+If received skb in batadv_v_elp_packet_recv or batadv_v_ogm_packet_recv
+is either cloned or non linearized then its data buffer will be
+reallocated by batadv_check_management_packet when skb_cow or
+skb_linearize get called. Thus geting ethernet header address inside
+skb data buffer before batadv_check_management_packet had any chance to
+reallocate it could lead to the following kernel panic:

+Date: Wed, 19 Jul 2023 10:15:05 +0200
+Subject: batman-adv: Trigger events for auto adjusted MTU
+
+If an interface changes the MTU, it is expected that an NETDEV_PRECHANGEMTU
+and NETDEV_CHANGEMTU notification events is triggered. This worked fine for
+.ndo_change_mtu based changes because core networking code took care of it.
+But for auto-adjustments after hard-interfaces changes, these events were
+simply missing.
+
+Due to this problem, non-batman-adv components weren't aware of MTU changes
+and thus couldn't perform their own tasks correctly.

+Subject: batman-adv: Don't increase MTU when set by user
+
+If the user set an MTU value, it usually means that there are special
+requirements for the MTU. But if an interface gots activated, the MTU was
+always recalculated and then the user set value was overwritten.
+
+The only reason why this user set value has to be overwritten, is when the
+MTU has to be decreased because batman-adv is not able to transfer packets

+The automatic recalculation of the maximum allowed MTU is usually triggered
