* net: TCP_MSS_DEFAULT, TCP_MSS_DESIREDWilliam Allen Simpson2009-11-13
| | | | | | | | | | | | | | | Define two symbols needed in both kernel and user space. Remove old (somewhat incorrect) kernel variant that wasn't used in most cases. Default should apply to both RMSS and SMSS (RFC2581). Replace numeric constants with defined symbols. Stand-alone patch, originally developed for TCPCT.

* vlan/macvlan: propagate transmission state to upper layersPatrick McHardy2009-11-13
| | | | | | | | | | Both vlan and macvlan devices usually don't use a qdisc and immediately queue packets to the underlying device. Propagate transmission state of the underlying device to the upper layers so they can react on congestion and/or inform the sending process.

* net: allow to propagate errors through ->ndo_hard_start_xmit()Patrick McHardy2009-11-13
| | | | | | | | | | | | | | | | | | Currently the ->ndo_hard_start_xmit() callbacks are only permitted to return one of the NETDEV_TX codes. This prevents any kind of error propagation for virtual devices, like queue congestion of the underlying device in case of layered devices, or unreachability in case of tunnels. This patches changes the NET_XMIT codes to avoid clashes with the NETDEV_TX codes and changes the two callers of dev_hard_start_xmit() to expect either errno codes, NET_XMIT codes or NETDEV_TX codes as return value. In case of qdisc_restart(), all non NETDEV_TX codes are mapped to NETDEV_TX_OK since no error propagation is possible when using qdiscs. In case of dev_queue_xmit(), the error is propagated upwards.

* net/atm: move all compat_ioctl handling to atm/ioctl.cArnd Bergmann2009-11-11
| | | | | | | | | | | | | | | | | | | | | | | | | We have two implementations of the compat_ioctl handling for ATM, the one that we have had for ages in fs/compat_ioctl.c and the one added to net/atm/ioctl.c by David Woodhouse. Unfortunately, both versions are incomplete, and in practice we use a very confusing combination of the two. For ioctl numbers that have the same identifier on 32 and 64 bit systems, we go directly through the compat_ioctl socket operation, for those that differ, we do a conversion in fs/compat_ioctl.c. This patch moves both variants into the vcc_compat_ioctl() function, while preserving the current behaviour. It also kills off the COMPATIBLE_IOCTL definitions that we never use here. Doing it this way is clearly not a good solution, but I hope it is a step into the right direction, so that someone is able to clean up this mess for real.

* net/compat: fix dev_ifsioc emulation corner casesArnd Bergmann2009-11-11
| | | | | | | | | | | | | | | | | | | Handling for SIOCSHWTSTAMP is broken on architectures with a split user/kernel address space like s390, because it passes a real user pointer while using set_fs(KERNEL_DS). A similar problem might arise the next time somebody adds code to dev_ifsioc. Split up dev_ifsioc into three separate functions for SIOCSHWTSTAMP, SIOC*IFMAP and all other numbers so we can get rid of set_fs in all potentially affected cases.

* DM9000: Wake on LAN supportBen Dooks2009-11-11
| | | | | | | | | | | | | | | Add support for Wake on LAN (WOL) reception and waking the device up from this signal via the ethtool interface. Currently we are only supporting the magic-packet variant of wakeup. WOL is enabled by specifying a second interrupt resource to the driver which indicates where the interrupt for the WOL is being signalled. This then enables the necessary ethtool calls to leave the device in a state to receive WOL frames when going into suspend.

* netdev: fold name hash properly (v3)stephen hemminger2009-11-11
| | | | | | | | | | | | | | | | | The full_name_hash function does not produce well distributed values in the lower bits, so most code uses hash_32() to fold it. This is really a bug introduced when name hashing was added, back in 2.5 when I added name hashing. hash_32 is all that is needed since full_name_hash returns unsigned int which is only 32 bits on 64 bit platforms. Also, there is no point in using hash_32 on ifindex, because the is naturally sequential and usually well distributed.

* gianfar: Revive SKB recyclingAnton Vorontsov2009-11-11
| | | | | | | | | | | | | | | | | | Before calling gfar_clean_tx_ring() the driver grabs an irqsave spinlock, and then tries to recycle skbs. But since skb_recycle_check() returns 0 with IRQs disabled, we'll never recycle any skbs. It appears that gfar_clean_tx_ring() and gfar_start_xmit() are mostly idependent and can work in parallel, except when they modify num_txbdfree. So we can drop the lock from most sections and thus fix the skb recycling.

* skbuff: Do not allow skb recycling with disabled IRQsAnton Vorontsov2009-11-11
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | NAPI drivers try to recycle SKBs in their polling routine, but we generally don't know the context in which the polling will be called, and the skb recycling itself may require IRQs to be enabled. This patch adds irqs_disabled() test to the skb_recycle_check() routine, so that we'll not let the drivers hit the skb recycling path with IRQs disabled. As a side effect, this patch actually disables skb recycling for some [broken] drivers. E.g. gianfar driver grabs an irqsave spinlock during TX ring processing, and then tries to recycle an skb, and that caused the following badness: nf_conntrack version 0.5.0 (1008 buckets, 4032 max) ------------[ cut here ]------------ Badness at kernel/softirq.c:143 NIP: c003e3c4 LR: c423a528 CTR: c003e344 ...

| * iwlwifi: Use RTS/CTS as the preferred protection mechanism for 6000 seriesWey-Yi Guy2009-11-10

In an HT Beacon, HT stations use the "Operating Mode" field in the HT Information Element to determine whether or not to use protection. The Operating Mode field has 4 possible settings: 0-3: Mode 0: If all stations in the BSS are 20/40 MHz HT capable, or if the BSS is 20/40 MHz capable, or if all stations in the BSS are 20 MHz HT stations in a 20 MHz BSS Mode 1: used if there are non-HT stations or APs using the primary or secondary channels Mode 2: if only HT stations are associated in the BSS and at least one 20 MHz HT station is associated. Mode 3: used if one or more non-HT stations are associated in the BSS. When in operating modes 1 or 3, and the Use_Protection field is 1 in the Beacon's ERP IE, all HT transmissions must be protected using RTS/CTS or CTS-to-Self. By default, CTS-to-self is the preferred protection mechanism for less overhead and higher throughput; but using the full RTS/CTS will better protect the inner exchange from interference, especially in highly-congested environment. For 6000 series WIFI NIC, RTS/CTS protection mechanism is the recommended choice for HT traffic based on the HW design.
