Appreciate these patches. Finally some love for sctp. Small comment below: On 16-04-09 12:53 AM, Xin Long wrote:
sctp_diag will dump some important details of sctp's assoc or ep, we use sctp_info to describe them, sctp_get_sctp_info to get them, and export it to sctp_diag.ko.

Can you double check to make sure this is 32 bit aligned (no holes) maybe in your case 64 bit aligned? Sticking + __u16 sctpi_p_error in there seems to kill it. Also, any plans to do the netlink events and destroy features? cheers, jamal -- To unsubscribe from this list: send the line "unsubscribe linux-sctp" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
