Eric Dumazet b9553558b4 vxlan: use pskb_network_may_pull() for transmit path header pulls ... In vxlan_xmit(), arp_reduce(), and vxlan_mdb_entry_skb_get(), pskb_may_pull() was being called to verify the availability of network layer headers (ARP, IPv6/ND, IP/IPv6 MDB keys). However, during transmit skb->data points to the MAC header, so skb_network_offset(skb) is ETH_HLEN (14 bytes). Using pskb_may_pull(skb, len) only checks len bytes from skb->data rather than skb_network_offset(skb) + len, which can leave part of the network header in non-linear frags. Replace these remaining pskb_may_pull() calls with pskb_network_may_pull() to properly account for the MAC header offset. Fixes: e4f67addf1 ("add DOVE extensions for VXLAN") Fixes: f564f45c45 ("vxlan: add ipv6 proxy support") Fixes: 0f83e69f44 ("vxlan: Add MDB data path support") Signed-off-by: Eric Dumazet <edumazet@google.com> Cc: stable@vger.kernel.org Reviewed-by: Vadim Fedorenko <vadim.fedorenko@linux.dev> Reviewed-by: Ido Schimmel <idosch@nvidia.com> Link: https://patch.msgid.link/20260723144249.759100-6-edumazet@google.com Signed-off-by: Jakub Kicinski <kuba@kernel.org>		2026-07-27 15:16:15 -07:00
