2013-01-18enic: change sprintf() to snprintf()Dan Carpenter
These are copying data into 16 char arrays. They all specify that the first string can't be more than 11 characters but once you add on the "-rx-" and the NUL character there isn't space for the %d. The first string is probably never going to be 11 characters, but if it is then let's truncate the string instead of corrupting memory.

2013-01-18net: ethernet: davinci_cpdma: Add boundary for rx and tx descriptorsMugunthan V N
When there is heavy transmission traffic in the CPDMA, then Rx descriptors memory is also utilized as tx desc memory looses all rx descriptors and the driver stops working then. This patch adds boundary for tx and rx descriptors in bd ram dividing the descriptor memory to ensure that during heavy transmission tx doesn't use rx descriptors. This patch is already applied to davinci_emac driver, since CPSW and davici_dmac shares the same CPDMA, moving the boundry seperation from Davinci EMAC driver to CPDMA driver which was done in the following commit commit 86d8c07ff2448eb4e860e50f34ef6ee78e45c40c Author: Sascha Hauer <s.hauer@pengutronix.de> Date: Tue Jan 3 05:27:47 2012 +0000 net/davinci: do not use all descriptors for tx packets The driver uses a shared pool for both rx and tx descriptors. During open it queues fixed number of 128 descriptors for receive packets. For each received packet it tries to queue another descriptor. If this fails the descriptor is lost for rx. The driver has no limitation on tx descriptors to use, so it can happen during a nmap / ping -f attack that the driver allocates all descriptors for tx and looses all rx descriptors. The driver stops working then. To fix this limit the number of tx descriptors used to half of the descriptors available, the rx path uses the other half. Tested on a custom board using nmap / ping -f to the board from two different hosts. Signed-off-by: Mugunthan V N <mugunthanvnm@ti.com> Signed-off-by: David S. Miller <davem@davemloft.net>

2013-01-18igb: Add mechanism for detecting latched hardware Rx timestampMatthew Vick
Add a check against possible Rx timestamp freezing in the hardware via watchdog mechanism. This situation can occur when an Rx timestamp has been latched, but the packet has been dropped because the Rx ring is full. Whenever a packet comes in that should be timestamped, the Rx timestamp gets latched into the hardware registers and we will store the jiffy value in the rx_ring. The watchdog will keep track of his own jiffy timer whenever there is no valid timestamp in the registers. If the watchdog detects a valid timestamp in the registers, meaning that no Rx packet has consumed it yet, it will check which time is most recent: the last time in the watchdog or any time in the rx_rings. If the most recent "event" was more than 5 seconds ago, it will flush the Rx timestamp and print a warning message to the syslog.

Since submit 621b4d6 the bnx2x driver support FW GRO. However, when using the device with GRO enabled in bridging scenarios throughput is very low, as the bridge expects all incoming packets to be passed with CHECKSUM_PARTIAL - a demand which is satisfied by the SW GRO implementation, but was missed in the bnx2x driver implementation (which returned CHECKSUM_UNNECESSARY). Now, given that the traffic is supported by FW GRO (TCP/IP), the bnx2x driver calculates the pseudo checksum by itself, passing skbs with CHECKSUM_PARTIAL and giving a much better throughput when receiving GRO traffic.
