The variable 'copied' is used in udp_recvmsg() to emphasize that the passed 'len' is adjusted to fit the actual datagram length. But the same can be done by adjusting 'len' directly. This patch thus removes the indirection. Signed-off-by:

DCCP is datagram-oriented but lacks UDP's support for MSG_TRUNC as defined in recvmsg(2)/recv(2). Hence the following 'Hello world\0' receiver len = recv(fd, buf, 10, MSG_PEEK | MSG_TRUNC); wrongly (always) returns 10, while in UDP it returns 12 as expected. This patch adds the missing MSG_TRUNC support to recvmsg(). Signed-off-by:

Rewrite sky2_reset to work with interrupts disabled and avoid freeing and reallocing memory. The old code used sky2_down and sky2_up to implement sky2_reset, which meant interrupts could not be disabled, and the transmit and receive ring buffers would be free'd and reallocated. To avoid the interrupt handler waking the transmit queue while we're doing a reset, it's better to have interrupts and NAPI polls disabled. Note: Modified Mike's patch to do IRQ disable in sky2_down before calling sky2_hw_down - Stephen Signed-off-by:

Allocate everything in one place so there's a single point of failure in sky2_up, and sky2_rx_start can no longer fail. Don't leave the hardware in a partially initialized state in the case rx ring allocation fails. As with the old code, the rx ring still needs to be fully allocated for sky2_up to succeed.

Change how FIFO is programmed in jumbo mode (to match vendor driver). Mostly cosmetic, the only register change is that the bits 22,23 are not programemd used. Signed-off-by:

This bit is not changed by vendor driver, and should be left alone. The documentation implies this a debug bit. 0 = WAKE# only asserted when VMAIN not available 1 = WAKE# is depend on wake events and independent of VMAIN. Signed-off-by:

Change Wake On Lan code to be similar to vendor driver. The definition of Y2_HW_WOL_ON is confusing; what it means is transition to firmware SPI setting when doing power change. Since same code is done for both shutdown and suspend, use common code path. Signed-off-by:

Logging messages sometimes had duplicated "ATL1E" output. For instance: ATL1E 0000:03:00.0: ATL1E: eth0 NIC Link is Up<100 Mbps Full Duplex> is now: ATL1E 0000:03:00.0: eth0: NIC Link is Up <100 Mbps Full Duplex> Add some consistency to logging messages Add some missing \n's to logging messages Miscellaneous typo spelling corrections Change atl1e_validate_option argument from pdev to adapter Signed-off-by:

These netdev_printk routines take a struct net_device * and emit dev_printk logging messages adding "%s: " ... netdev->dev.parent to the dev_printk format and arguments. This can create some uniformity in the output message log. These helpers should not be used until a successful alloc_netdev. Signed-off-by:

Permanent IPV6 addresses should not be removed when the link is set to admin down, only when device is removed. When link is lost permanent addresses should be marked as tentative so that when link comes back they are subject to duplicate address detection (if DAD was enabled for that address). Other routing systems keep manually configured IPv6 addresses when link is set down. Signed-off-by:

Add Micrel KSZ8841/KSZ8842 PCI Ethernet chip support. Signed-off-by:
-
Tristram Ha authored
This is a new network driver for Micrel KSZ8841/KSZ8842 PCI Ethernet chips. The same driver can run both chips at the same time. It supports IPv4 TCP hardware checksumming and so can use scatter/gather transmission. The KSZ8842 switch has 2 ports. Some users like to take direct control of those ports. So KSZ8842 has a multiple devices mode in which the driver creates another network device so that users can specify which port to send packets. This mode is enabled by passing the "multi_dev=1" parameter to the driver during loading. The KSZ884X can receive huge frames with size up to 1916 bytes. To use this feature change the network device MTU from 1500 to 1898. The KSZ884X driver has 3 packet receive processing functions for the normal mode, multiple devices mode, and huge frame mode. Those functions are identical except for more checking for the new features. In normal programming point of view the huge frame version is the one to use because it covers all the cases, but this is done for performance consideration because the target clients for the KSZ884X chips are embedded systems, which unlike desktop PC may not have powerful CPU.

A pointer to am79c961_probe is passed to the core via platform_driver_register and so the function must not disappear when the .init sections are discarded. Otherwise (if also having HOTPLUG=y) unbinding and binding a device to the driver via sysfs will result in an oops as does a device being registered late. An alternative to this patch is using platform_driver_probe instead of platform_driver_register plus removing the pointer to the probe function from the struct platform_driver. Signed-off-by:

When the fib size exceeds what can be dumped in a single skb, the dump is suspended and resumed once the last skb has been received by userspace. When the fib is changed while the dump is suspended, the walker might contain stale pointers, causing a crash when the dump is resumed.

This fixes a problem in the DCCP getsockopt() API: currently there is no way for a user to a priori know the number of built-in CCIDs, other than trying DCCP_SOCKOPT_AVAILABLE_CCIDS in a loop, incrementing the option length until EINVAL is no longer returned. This patch truncates the array to the user-provided length. No copy is made when the length is <= 0. Due to the length restriction in do_dccp_getsockopt() to sizeof(int), the minimum array length remains 4, which is a reasonable default (only 3 CCIDs, CCID-2..4, are currently defined).
