[linux-merge]linux integration; branch, batadv/lts/5.15, updated. v5.15.83-17-gd68f50bfb00f

by postmaster＠open-mesh.org

The following commit has been merged in the batadv/lts/5.15 branch: commit 0cac1c84e1ccdd71924c644f83e24f5ef47d6f7c Author: Sebastian Andrzej Siewior <bigeasy(a)linutronix.de> Date: Tue Jul 19 18:08:12 2022 +0200 batman-adv: Use netif_rx_any_context() any. This reverts the stable commit e65d78b12fbc0 ("batman-adv: Use netif_rx().") The commit message says: | Since commit | baebdf48c3600 ("net: dev: Makes sure netif_rx() can be invoked in any context.") | | the function netif_rx() can be used in preemptible/thread context as | well as in interrupt context. This commit (baebdf48c3600) has not been backported to the 5.15 stable series and therefore, the commit which builds upon it, must not be backported either. Revert the backport and use netif_rx_any_context() again.

The following commit has been merged in the batadv/lts/5.15 branch: commit 8f37aad74f46dd5d8b95fac17804b75f77931fa9 Author: Sven Eckelmann <sven(a)narfation.org> Date: Sat Apr 16 13:51:10 2022 +0200 batman-adv: Don't skb_split skbuffs with frag_list [ Upstream commit a063f2fba3fa633a599253b62561051ac185fa99 ] The receiving interface might have used GRO to receive more fragments than MAX_SKB_FRAGS fragments. In this case, these will not be stored in skb_shinfo(skb)->frags but merged into the frag list. batman-adv relies on the function skb_split to split packets up into multiple smaller packets which are not larger than the MTU on the outgoing interface. But this function cannot handle frag_list entries and is only operating on skb_shinfo(skb)->frags. If it is still trying to split such an skb and xmit'ing it on an interface without support for NETIF_F_FRAGLIST, then validate_xmit_skb() will try to linearize it. But this fails due to inconsistent information. And __pskb_pull_tail will trigger a BUG_ON after skb_copy_bits() returns an error. In case of entries in frag_list, just linearize the skb before operating on it with skb_split().
