3.6.11.4 stable review patch. If anyone has any objections, please let me know. ------------------ From: Patrick McHardy <kaber@xxxxxxxxx> [ Upstream commit 3a7b21eaf4fb3c971bdb47a98f570550ddfe4471 ] Some Cisco phones create huge messages that are spread over multiple packets. After calculating the offset of the SIP body, it is validated to be within the packet and the packet is dropped otherwise. This breaks operation of these phones. Since connection tracking is supposed to be passive, just let those packets pass unmodified and untracked.
