* rndis_wlan: cleanup: rename all rndis_wext* objects to rndis_wlan*Jussi Kivilinna2009-06-10
| | | | | | | | | | Driver used to be named rndis_wext before inclusion to upstream. Since rndis_wlan is being converted to cfg80211, use of rndis_wext* names can be confusing. So rename all rndis_wext to rndis_wlan (as should have been when driver was renamed). Signed-off-by: Jussi Kivilinna <jussi.kivilinna@mbnet.fi> Signed-off-by: John W.

| | | | | | | | | | | | e1000e_config_collision_dist() sets tctl, but subsequently tctl is overwritten. It seems to me that as things stand the call to e1000e_config_collision_dist() has no effect and should either be removed or moved down a little bit. This kernel patch takes the latter option.

* e1000e: Fixes possible phy corrupton on 82571 designs.Dave Graham2009-06-09
| | | | | | | | | | | | | | | Phy corruption has been observed on 2-port 82571 adapters, and is root-caused to lack of synchronization between the 2 driver instances, which conflict when attempting to access the phy via the single MDIC register. A semaphore exists for this purpose, and is now used on these designs. Because PXE &/or EFI boot code (which we cannot expect to be built with this fix) may leave the inter-instance semaphore in an invalid initial state when the driver first loads, this fix also includes a one-time (per driver load) fix-up of the semaphore initial state.

* net: add IEEE 802.15.4 socket family implementationSergey Lapin2009-06-09
| | | | | | | | | | | | | | | | | | | | Add support for communication over IEEE 802.15.4 networks. This implementation is neither certified nor complete, but aims to that goal. This commit contains only the socket interface for communication over IEEE 802.15.4 networks. One can either send RAW datagrams or use SOCK_DGRAM to encapsulate data inside normal IEEE 802.15.4 packets. Configuration interface, drivers and software MAC 802.15.4 implementation will follow. Initial implementation was done by Maxim Gorbachyov, Maxim Osipov and Pavel Smolensky as a research project at Siemens AG. Later the stack was heavily reworked to better suit the linux networking model, and is now maitained as an open project partially sponsored by Siemens.

* pkt_sched: Change PSCHED_SHIFT from 10 to 6Jarek Poplawski2009-06-09
| | | | | | | | | | | | | | | | | | | | | Change PSCHED_SHIFT from 10 to 6 to increase schedulers time resolution. This will increase 16x a number of (internal) ticks per nanosecond, and is needed to improve accuracy of schedulers based on rate tables, like HTB, TBF or CBQ, with rates above 100Mbit. It is assumed this change is safe for 32bit accounting of time diffs up to 2 minutes, which should be enough for common use (extremely low rate values may overflow, so get inaccurate instead). To make full use of this change an updated iproute2 will be needed. (But using older iproute2 should be safe too.) This change breaks ticks - microseconds similarity, so some minor code fixes might be needed. It is also planned to change naming adequately eg. to PSCHED_TICKS2NS() etc. in the near future.

* be2net: Remove unnecessary frag list traversing.David S. Miller2009-06-09
| | | | | | | | | | | | | | | | | | | | | | This driver does not indicate support for frag lists. Furthermore, even if it did, the code is walking the frag lists incorrectly. The idiom is: for (iter = skb_shinfo(skb)->frag_list; iter; iter = iter->next) but it's doing: for (iter = skb_shinfo(skb)->frag_list; iter; iter = skb_shinfo(iter)->frag_list) which would never work. And this proves that this driver never saw an SKB with active frag lists. So just remove the code altogether and the driver TX path becomes much simpler. Signed-off-by: David S.

* declance: Restore tx descriptor ring lockingMaciej W. Rozycki2009-06-08
| | | | | | | | | | | | | | | | | | | | | | | | | A driver overhaul on 29 Feb 2000 (!) broke locking around fiddling with the tx descriptor ring in start_xmit(); a follow-on "fix" removed the broken remnants altogether. Here's a patch to restore proper locking in the function -- the complement in the interrupt handler has been correct all the time. This *may* have been the reason for the occasional confusion of the chip -- triggering a tx timeout followed by a chip reset sequence -- seen on R4k-based DECstations with the onboard Ethernet interface. Another theory is the confusion is due to an unindentified problem -- perhaps a silicon erratum -- associated with the variation of the MT ASIC used to interface the R4k CPU to the rest of the system on these computers; with its aggressive write-back buffering the design is particularly weakly ordered when it comes to MMIO (in the absence of ordering barriers uncached reads are allowed to bypass earlier uncached writes, even if to the same location), which may trigger all kinds of corner cases in peripheral hardware as well as software. Either way this piece of code is buggy. Signed-off-by: Maciej W. Rozycki <macro@linux-mips.org> Signed-off-by: David S. Miller <davem@davemloft.net>

* tun: Fix unregister raceEric W. Biederman2009-06-08
| | | | | | | | | | | | | | | | | | It is possible for tun_chr_close to race with dellink on the a tun device. In which case if __tun_get runs before dellink but dellink runs before tun_chr_close calls unregister_netdevice we will attempt to unregister the netdevice after it is already gone. The two cases are already serialized on the rtnl_lock, so I have gone for the cheap simple fix of moving rtnl_lock to cover __tun_get in tun_chr_close. Eliminating the possibility of the tun device being unregistered between __tun_get and unregister_netdevice in tun_chr_close. Signed-off-by: Eric W.
