2011-11-29tcp: do not scale TSO segment size with reordering degreeNeal Cardwell3-2/+10
Since 2005 (c1b4a7e69576d65efc31a8cea0714173c2841244) tcp_tso_should_defer has been using tcp_max_burst() as a target limit for deciding how large to make outgoing TSO packets when not using sysctl_tcp_tso_win_divisor. But since 2008 (dd9e0dda66ba38a2ddd1405ac279894260dc5c36) tcp_max_burst() returns the reordering degree. We should not have tcp_tso_should_defer attempt to build larger segments just because there is more reordering. This commit splits the notion of deferral size used in TSO from the notion of burst size used in cwnd moderation, and returns the TSO deferral limit to its original value.

2011-11-29NET: NETROM: When adding a route verify length of mnemonic string.Ralf Baechle1-0/+5
struct nr_route_struct's mnemonic permits a string of up to 7 bytes to be used. If userland passes a not zero terminated string to the kernel adding a node to the routing table might result in the kernel attempting to read copy a too long string. Mnemonic is part of the NET/ROM routing protocol; NET/ROM routing table updates only broadcast 6 bytes. The 7th byte in the mnemonic array exists only as a \0 termination character for the kernel code's convenience. Fixed by rejecting mnemonic strings that have no terminating \0 in the first 7 characters. Do this test only NETROM_NODE to avoid breaking NETROM_NEIGH where userland might passing an uninitialized mnemonic field. Initial patch by Dan Carpenter <dan.carpenter@oracle.com>.

2011-11-28tg3: Scale back code that modifies MRRSMatt Carlson1-17/+10
Tg3 normally gets a performance boost by increasing the PCI Maximum Read Request Size (MRRS) to 4k. Unfortunately, this is causing some problems on particular hardware platforms. This patch removes all code that modifies the MRRS except for one case. As part of a solution to fix an internal FIFO problem on the 5719, the driver artificially capped the MRRS to 2k for the entire 5719, and later 5720, ASIC revs. This was overly aggressive and only really needed to be done for the 5719 A0. In the spirit of the rest of this patch, the driver will only reprogram the MRRS for this device if the value exceeds the 2k cap.

2011-11-28tg3: Fix TSO CAP for 5704 devs w / ASF enabledMatt Carlson1-2/+12
On the earliest TSO capable devices, TSO was accomplished through firmware. The TSO cannot coexist with ASF management firmware though. The tg3 driver determines whether or not ASF is enabled by calling tg3_get_eeprom_hw_cfg(), which checks a particular bit of NIC memory. Commit dabc5c670d3f86d15ee4f42ab38ec5bd2682487d, entitled "tg3: Move TSO_CAPABLE assignment", accidentally moved the code that determines TSO capabilities earlier than the call to tg3_get_eeprom_hw_cfg(). As a consequence, the driver was attempting to determine TSO capabilities before it had all the data it needed to make the decision. This patch fixes the problem by revisiting and reevaluating the decision after tg3_get_eeprom_hw_cfg() is called.

2011-11-27tcp: skip cwnd moderation in TCP_CA_Open in tcp_try_to_openNeal Cardwell1-1/+2
The problem: Senders were overriding cwnd values picked during an undo by calling tcp_moderate_cwnd() in tcp_try_to_open(). The fix: Don't moderate cwnd in tcp_try_to_open() if we're in TCP_CA_Open, since doing so is generally unnecessary and specifically would override a DSACK-based undo of a cwnd reduction made in fast recovery.

2011-11-27tcp: allow undo from reordered DSACKsNeal Cardwell1-13/+2
Previously, SACK-enabled connections hung around in TCP_CA_Disorder state while snd_una==high_seq, just waiting to accumulate DSACKs and hopefully undo a cwnd reduction. This could and did lead to the following unfortunate scenario: if some incoming ACKs advance snd_una beyond high_seq then we were setting undo_marker to 0 and moving to TCP_CA_Open, so if (due to reordering in the ACK return path) we shortly thereafter received a DSACK then we were no longer able to undo the cwnd reduction. The change: Simplify the congestion avoidance state machine by removing the behavior where SACK-enabled connections hung around in the TCP_CA_Disorder state just waiting for DSACKs. Instead, when snd_una advances to high_seq or beyond we typically move to TCP_CA_Open immediately and allow an undo in either TCP_CA_Open or TCP_CA_Disorder if we later receive enough DSACKs.

2011-11-27tcp: use SACKs and DSACKs that arrive on ACKs below snd_unaNeal Cardwell1-3/+7
The bug: When the ACK field is below snd_una (which can happen when ACKs are reordered), senders ignored DSACKs (preventing undo) and did not call tcp_fastretrans_alert, so they did not increment prr_delivered to reflect newly-SACKed sequence ranges, and did not call tcp_xmit_retransmit_queue, thus passing up chances to send out more retransmitted and new packets based on any newly-SACKed packets. The change: When the ACK field is below snd_una (the "old_ack" goto label), call tcp_fastretrans_alert to allow undo based on any newly-arrived DSACKs and try to send out more packets based on newly-SACKed packets.
