Hi. Won't tell about panic in tcp_sacktag_walk() since I cannot trigger it intentionally, but setting net.ipv4.tcp_retrans_collapse to 0 *does not* fix warning in tcp_fastretrans_alert() for me. On středa 27. září 2017 2:18:32 CEST Yuchung Cheng wrote: > On Tue, Sep 26, 2017 at 5:12 PM,

[REGRESSION] Warning in tcp_fastretrans_alert() of net/ipv4/tcp_input.c

Hello. Since, IIRC, v4.11, there is some regression in TCP stack resulting in the warning shown below. Most of the time it is harmless, but rarely it just causes either freeze or (I believe, this is related too) panic in tcp_sacktag_walk() (because sk_buff passed to this function is NULL).

[REGRESSION] Warning in tcp_fastretrans_alert() of net/ipv4/tcp_input.c

Hello. Since, IIRC, v4.11, there is some regression in TCP stack resulting in the warning shown below. Most of the time it is harmless, but rarely it just causes either freeze or (I believe, this is related too) panic in tcp_sacktag_walk() (because sk_buff passed to this function is NULL).
