2007-10-10[AF_IUCV]: postpone receival of iucv-packetsUrsula Braun2-86/+132
AF_IUCV socket programs may waste Linux storage, because af_iucv allocates an skb whenever posted by the receive callback routine and receives the message immediately. Message receival is now postponed if data from previous callbacks has not yet been transferred to the receiving socket program. Instead a message handle is saved in a message queue as a reminder. Once messages could be given to the receiving socket program, there is an additional checking for entries in the message queue, followed by skb allocation and message receival if applicable.

2007-10-10[TG3]: Fix ethtool autonegotiate flags.Andy Gospodarek1-1/+2
I recently noticed that when calling: # ethtool -s eth0 autoneg on on a 5722 (though I'm sure it's not specific to that card) that subsequent checks of the cards status looked like this: # ethtool eth0 Settings for eth0: Supported ports: [ MII ] Supported link modes: 10baseT/Half 10baseT/Full 100baseT/Half 100baseT/Full 1000baseT/Half 1000baseT/Full Supports auto-negotiation: Yes Advertised link modes: 10baseT/Half 10baseT/Full 100baseT/Half 100baseT/Full 1000baseT/Half 1000baseT/Full Advertised auto-negotiation: No <---- This seems odd?!?

Honor the advertisement bitmask from ethtool. We used to always advertise the full capability when autoneg was set to on. changed things around so that ethtool speed settings were strictly followed. Unfortunately ethtool doesn't seem to set ADVERTISED_Autoneg in the advertising field (and maybe it shouldn't have to). I'd vote that it should be fixed there, but it should also be added here just in case someone using ethtool ioctls in their own application gets what they want. Adding that flag in tg3_set_settings seemed like the most logical place since the driver works fine on boot. This is just an issue when re-enabling autonegotiation, so we should probably nip it there.

2007-10-10[DCCP]: Twice the wrong reset code in receiving connection-RequestsGerrit Renker2-11/+7
This fixes two bugs in processing of connection-Requests in v{4,6}_conn_request: 1. Due to using the variable `reset_code', the Reset code generated internally by dccp_parse_options() is overwritten with the initialised value ("Too Busy") of reset_code, which is not what is intended. 2. When receiving a connection-Request on a multicast or broadcast address, no Reset should be generated, to avoid storms of such packets. Instead of jumping to the `drop' label, the v{4,6}_conn_request functions now return 0. Below is why in my understanding this is correct: When the conn_request function returns < 0, then the caller, dccp_rcv_state_process(), returns 1. In all instances where dccp_rcv_state_process is called (dccp_v4_do_rcv, dccp_v6_do_rcv, and dccp_child_process), a return value of != 0 from dccp_rcv_state_process() means that a Reset is generated. If on the other hand the conn_request function returns 0, the packet is discarded and no Reset is generated. Note: There may be a related problem when sending the Response, due to the following. if (dccp_v6_send_response(sk, req, NULL)) goto drop_and_free; /* ... */ drop_and_free: return -1; In this case, if send_response fails due to transmission errors, the next thing that is generated is a Reset with a code "Too Busy". I haven't been able to conjure up such a condition, but it might be good to change the behaviour here also (not done by this patch).

2007-10-10[CCID2]: Sequence number wraparound issuesGerrit Renker1-3/+4
