When processing the unregister notify for a hard interface, removing the sysfs files may lead to a circular deadlock (rtnl mutex <-> s_active). To overcome this problem, postpone the sysfs removal in a worker. Reported-by:

A delayed_work struct does not need to be initialized each every time before being enqueued. Therefore the INIT_DELAYED_WORK() macro should be used during the initialization process only. Signed-off-by:

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. Signed-off-by:

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 86d8c07f 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:

Jeff Kirsher says: ==================== This series contains updates to e1000e and igb. Most notably is the added timestamp support in e1000e and additional software timestamp support in igb. As well as, the added thermal data support and SR-IOV configuration support in igb. v2- dropped the following patches from the previous 14 patch series because changes were requested from the community: e1000e: add support for IEEE-1588 PTP igb: Report L4 Rx hash via skb->l4_rxhash ==================== Signed-off-by: -

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. Cc: Richard Cochran <richardcochran@gmail.com> Signed-off-by:

When transmitting a packet that must return a Tx timestamp, a work item gets scheduled to poll for the Tx timestamp being completed in hardware. Add a timeout on this work item of 15 seconds from when the driver gets the skb, after which it will stop polling. Report via stats and system log if this occurs.

Use the standard #defines for PCIe Capability ASPM fields. Previously we used PCIE_LINK_STATE_L0S and PCIE_LINK_STATE_L1 directly, but these are defined for the Linux ASPM interfaces, e.g., pci_disable_link_state(), and only coincidentally match the actual register bits. PCIE_LINK_STATE_CLKPM, also part of that interface, does not match the register bit. Signed-off-by:
