Re: Oops in arm kernel 4.4.32 on d_tcp_parse_packet
Yakir,
Great to know that the patches fix the first problem!
For the TCP-related problem, it looks like that the ROHC decompressor was "restarted" between the two SSH sessions. The decompressor seems indeed to have lost the information of the first SSH stream. Was the ROHC decompressor "rohc_decomp" object destroyed then created again?
Regards,
Didier
