Arnaldo, Setting tx_qlen=0 did not help, the receiver receives only 1 packet, despite of sender's sending 10 packets. Attached are the dmesg output of sender & receiver. I modified the DCCP code on the sender side to print some debug messages (input/output to/from functions, etc.). BTW, I am using CCID3. ----- Original Message ---- From: Arnaldo Carvalho de Melo <arnaldo.melo@xxxxxxxxx> To: Ian McDonald <ian.mcdonald@xxxxxxxxxxx> Cc: Leandro Melo de Sales <leandroal@xxxxxxxxx>; burak gorkemli <burakgorkemli@xxxxxxxxx>; DCCP Mailing List <dccp@xxxxxxxxxxxxxxx> Sent: Thursday, November 30, 2006 12:51:11 PM Subject: Re: On 11/29/06, Ian McDonald <ian.mcdonald@xxxxxxxxxxx> wrote: > Folks, > > Another thing to note is that with a limit on tx queue sizes now you > will get EAGAIN if the queue is full... Yes, 4, 5 packets should be, in dccp_sendmsg: if (sysctl_dccp_tx_qlen && (sk->sk_write_queue.qlen >= sysctl_dccp_tx_qlen)) { rc = -EAGAIN; goto out_release; } Leandro and Burak: could you please try setting sysctl_dccp_tx_qlen to zero? doing this: [root@qemu ~]# cat /proc/sys/net/dccp/default/tx_qlen 5 [root@qemu ~]# echo 0 > /proc/sys/net/dccp/default/tx_qlen [root@qemu ~]# cat /proc/sys/net/dccp/default/tx_qlen 0 [root@qemu ~]# And report the results? - Arnaldo - To unsubscribe from this list: send the line "unsubscribe dccp" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
