Revision 8872d8e1c4311dd7e5086975df9c76120a0be83b authored by Angelo P. Castellani on 17 May 2006, 04:42:11 UTC, committed by David S. Miller on 17 May 2006, 04:42:11 UTC
From: "Angelo P. Castellani" <angelo.castellani+lkml@gmail.com> Using NewReno, if a sk_buff is timed out and is accounted as lost_out, it should also be removed from the sacked_out. This is necessary because recovery using NewReno fast retransmit could take up to a lot RTTs and the sk_buff RTO can expire without actually being really lost. left_out = sacked_out + lost_out in_flight = packets_out - left_out + retrans_out Using NewReno without this patch, on very large network losses, left_out becames bigger than packets_out + retrans_out (!!). For this reason unsigned integer in_flight overflows to 2^32 - something. Signed-off-by: David S. Miller <davem@davemloft.net>
