2009-10-13x25: bit and/or confusion in x25_ioctl()?roel kluin
Looking at commit ebc3f64b864f it appears that this was intended and not the original, equivalent to `if (facilities.reverse & ~0x81)'. In x25_parse_facilities() that patch changed how facilities->reverse was set. No other bits were set than 0x80 and/or 0x01. Signed-off-by: Roel Kluin <roel.kluin@gmail.com> Signed-off-by: David S.

2009-10-13cxgb3: Added private MAC address and provisioning packet handler for iSCSIKaren Xie
This patch added support of private MAC address per port and provisioning packet handler for iSCSI traffic only. The above changes are isolated to the cxgb3 driver, independent of any scsi or iscsi driver changes.

2009-10-13can: make the number of echo skb's configurableWolfgang Grandegger
This patch allows the CAN controller driver to define the number of echo skb's used for the local loopback (echo), as suggested by Kurt Van Dijck, with the function: struct net_device *alloc_candev(int sizeof_priv, unsigned int echo_skb_max); The CAN drivers have been adapted accordingly. For the ems_usb driver, as suggested by Sebastian Haas, the number of echo skb's has been increased to 10, which improves the transmission performance a lot.

2009-10-13bonding: change bond_create_proc_entry() to return voidNicolas de Pesloüan
The function bond_create_proc_entry is currently of type int. Two versions of this function exist: The one in the ifdef CONFIG_PROC_FS branch always return 0. The one in the else branch (which is empty) return nothing. When CONFIG_PROC_FS is undef, this cause the following warning: drivers/net/bonding/bond_main.c: In function `bond_create_proc_entry': drivers/net/bonding/bond_main.c:3393: warning: control reaches end of non-void function No caller of this function use the returned value.

2009-10-12mdio: Advertise pause (flow control) settings even if autoneg is offBen Hutchings
Currently, if pause autoneg is off we do not set either pause advertising flag. If autonegotiation of speed and duplex settings is enabled, there is no way for the link partner to distinguish this from our refusing to use pause frames. We should instead set the advertising flags according to the forced mode so that the link partner can follow our lead. This is consistent with the behaviour of other drivers.

2009-10-12gianfar: Add support for hibernationAnton Vorontsov
Thanks to various cleanups and refactorings this is now straightforward: convert the gianfar driver to dev_pm_ops, plus add ->restore() callback that will fully reinitialize MAC internal registers and BDs. Note that I kept legacy suspend/resume callbacks so that this patch doesn't depend on PowerPC changes (i.e. dev_pm_ops support for OF platform drivers).

2009-10-12gianfar: Factor out gfar_init_bds() from gfar_alloc_skb_resources()Anton Vorontsov
After hibernation we want to just reinitialize BDs, no need to allocate anything. So, factor out BDs initialization code from gfar_alloc_skb_resourses(). Also, teach gfar_init_bds() to reuse already allocated RX SKBs, i.e. just call gfar_init_rxbdp() if a SKB was already allocated and mapped.

2009-10-12gianfar: Factor out RX BDs initialization from gfar_new_rxbdp()Anton Vorontsov
We want to just reinitialize RX BDs after hibernation, no need to map the skb->data again. So let's factor gfar_init_rxbdp() out of gfar_new_rxbdp(). Signed-off-by: Anton Vorontsov <avorontsov@ru.mvista.com> Signed-off-by: David S. Miller <davem@davemloft.net>
2009-10-12gianfar: Move tbase/rbase initialization to gfar_init_mac()Anton Vorontsov
For hibernation we want to call gfar_init_mac() without need to free/allocate_skb_resources sequence, so save the DMA address into a private struct, and move tbase/rbase initialization to gfar_init_mac().

2009-10-12gianfar: Split allocation and initialization steps out of startup_gfar()Anton Vorontsov
Two new functions implemented: gfar_alloc_skb_resources() and gfar_init_mac(). We'll use gfar_init_mac() for restoring after hibernation. The patch just moves the code around, there should be no functional changes. Signed-off-by: Anton Vorontsov <avorontsov@ru.mvista.com> Signed-off-by: David S. Miller <davem@davemloft.net>
2009-10-12gianfar: Don't needlessly set the wrap bit for the last RX BDAnton Vorontsov
startup_gfar() sets the wrap bit for the last rxbd just after gfar_new_rxbdp() call, which is issued for all rxbds. And gfar_new_rxbdp() has the following check already: if (bdp == priv->rx_bd_base + priv->rx_ring_size - 1) lstatus |= BD_LFLAG(RXBD_WRAP); So we don't need to set the bit again.

2009-10-12gianfar: Simplify skb resources freeing codeAnton Vorontsov
Remove dma_free_coherent() from stop_gfar() and gfar_start() calls, place it into free_skb_resources(). That makes SKB resources management more understandable, plus free_skb_resources() will be used as a cleanup routine for gfar_alloc_skb_resources() that will be implemented soon.

2009-10-12gianfar: Some cleanups for startup_gfar()Anton Vorontsov
We're going to split the startup_gfar() into 3 separate functions, so let's cleanup the code a little bit so that cosmetic changes won't distract attention from logical ones. - Remove needless casts (e.g. (struct sk_buff **)kmalloc()); - Turn 'unsigned long vaddr;' into 'void *vaddr', to avoid casting; - Add new 'struct device *dev' variable as a shorthand for '&priv->ofdev->dev' that is used all over the place, also rename 'struct net_device *dev' to 'struct net_device *ndev'; - Turn printk(KERN_ERR ...) to pr_err(...), which is shorter; - Don't return bogus -1 (i.e. -EPERM) when request_irq() fails; - Turn '&priv->regs->' to just '&regs->'.

2009-10-12net: Introduce recvmmsg socket syscallArnaldo Carvalho de Melo
Meaning receive multiple messages, reducing the number of syscalls and net stack entry/exit operations. Next patches will introduce mechanisms where protocols that want to optimize this operation will provide an unlocked_recvmsg operation. This takes into account comments made by: . Paul Moore: sock_recvmsg is called only for the first datagram, sock_recvmsg_nosec is used for the rest. . Caitlin Bestler: recvmmsg now has a struct timespec timeout, that works in the same fashion as the ppoll one. If the underlying protocol returns a datagram with MSG_OOB set, this will make recvmmsg return right away with as many datagrams (+ the OOB one) it has received so far. . Rémi Denis-Courmont & Steven Whitehouse: If we receive N < vlen datagrams and then recvmsg returns an error, recvmmsg will return the successfully received datagrams, store the error and return it in the next call. This paves the way for a subsequent optimization, sk_prot->unlocked_recvmsg, where we will be able to acquire the lock only at batch start and end, not at every underlying recvmsg call.

2009-10-12net: Generalize socket rx gap / receive queue overflow cmsgNeil Horman
Create a new socket level option to report number of queue overflows Recently I augmented the AF_PACKET protocol to report the number of frames lost on the socket receive queue between any two enqueued frames. This value was exported via a SOL_PACKET level cmsg. AFter I completed that work it was requested that this feature be generalized so that any datagram oriented socket could make use of this option. As such I've created this patch, It creates a new SOL_SOCKET level option called SO_RXQ_OVFL, which when enabled exports a SOL_SOCKET level cmsg that reports the nubmer of times the sk_receive_queue overflowed between any two given frames. It also augments the AF_PACKET protocol to take advantage of this new feature (as it previously did not touch sk->sk_drops, which this patch uses to record the overflow count). Tested successfully by me. Notes: 1) Unlike my previous patch, this patch simply records the sk_drops value, which is not a number of drops between packets, but rather a total number of drops. Deltas must be computed in user space. 2) While this patch currently works with datagram oriented protocols, it will also be accepted by non-datagram oriented protocols. I'm not sure if thats agreeable to everyone, but my argument in favor of doing so is that, for those protocols which aren't applicable to this option, sk_drops will always be zero, and reporting no drops on a receive queue that isn't used for those non-participating protocols seems reasonable to me. This also saves us having to code in a per-protocol opt in mechanism. 3) This applies cleanly to net-next assuming that commit 977750076d98c7ff6cbda51858bb5a5894a9d9ab (my af packet cmsg patch) is reverted Signed-off-by: Neil Horman <nhorman@tuxdriver.com> Signed-off-by: Eric Dumazet <eric.dumazet@gmail.com> Signed-off-by: David S.
