Package: src:linux
Version: 3.2.35-2
Severity: normal
IP_MTU socket option is not updated after 10 minutes of waiting for
SOCK_STREAM sockets when the value of socket option IP_MTU_DISCOVER
is IP_PMTUDISC_DO or IP_PMTUDISC_WANT.
This can be reproduced with 3 hosts configuration. Let it be the
hosts: host_A, host_B and host _C. host_A via interface eth1 connected with
host_B via intefaces eth1. Let host_C via interface eth1 connected with host_B
via interface eth2. Also Lets address 10.0.1.1/24 is assigned to eth1 on host_A;
10.0.1.2/24 is assigned to eth1 on host_B; 10.0.2.1/24 is assigned to eth2
on host_B; 10.0.2.2/24 is assigned to eth1 on host_C. Also there are two routes:
"10.0.2.2 via 10.0.1.2 dev eth1" on host_A and "10.0.1.1 via 10.0.2.1 dev eth1"
on host_C. Also forwarding is on on host_B. So we have the following picture:
host_A-eth1(10.0.1.1)<-->(10.0.1.2)eth1-host_B-eth2(10.0.2.1)<-->(10.0.2.2)eth1-host_C
MTU is equal to 1500 on all involved interfaces. Then we make the followign
steps:
on host_A:
1. socket(SOCK_STREAM) -> 6
2. bind(6, 10.0.1.1:25630) -> 0
3. listen(6, 1) -> 0
on host_C:
4. socket(SOCK_STREAM) -> 5
5. bind(5, 10.0.2.2:25631) -> 0
6. connect(5, 10.0.1.1:25630) -> 0
on host_A:
7. accept(6) -> 7
8. close(6) -> 0
9. getsockopt(7,IP_MTU) -> 0 // Returns that MTU is 1500
10. getsockopt(7,IP_MTU_DISCOVER) -> 0 // Returns that default value is
IP_PMTUDISC_WANT
On eth2 on host_B and on eth1 on host_C change MTU from 1500 to 750. Wait for a
while.
11. send(7, lenght=1400) -> 1400
On host_C:
12. recv(6) -> 1400
On host_A
13. sleep(5);
14. getsockopt(7,IP_MTU) -> 0 // Returns that MTU is 750
On eth2 on host_B and on eth1 on host_C change MTU from 750 to 1500. Wait for a
while.
Repeat the steps 15-18 for 20 minutes:
On host_A:
15. send(7, lenght=650) -> 650
On host_C:
16. recv(6) -> 650
On host_A:
17. sleep(60)
18. getsockopt(7,IP_MTU) -> 0 // Always returns that MTU is 750
So the value of IP_MTU socket option is not restored to 1500 even after 20
minutes.
There is the same picture if IP_MTU_DISCOVER is set to IP_PMTUDISC_DO at step
10.
