* hso: Fix stack corruption on some architecturesDaniel Gimpelevich2013-08-211-1/+5

* usbnet: do not pretend to support SG/TSOEric Dumazet2013-07-262-14/+7
| | | | | | | | | | | | | | | | | | | usbnet doesn't support yet SG, so drivers should not advertise SG or TSO capabilities, as they allow TCP stack to build large TSO packets that need to be linearized and might use order-5 pages. This adds an extra copy overhead and possible allocation failures. Current code ignore skb_linearize() return code so crashes are even possible. Best is to not pretend SG/TSO is supported, and add this again when/if usbnet really supports SG for devices who could get a performance gain.

The xen-netback conflict was overlapping changes involving the handling of the notify list in xen_netbk_rx_action(). Batman conflict resolution provided by Antonio Quartulli, basically keep everything in both conflict hunks. The nl80211 conflict is a little more involved. In 'net' we added a dynamic memory allocation to nl80211_dump_wiphy() to fix a race that Linus reported. Meanwhile in 'net-next' the handlers were converted to use pre and post doit handlers which use a flag to determine whether to hold the RTNL mutex around the operation. However, the dump handlers to not use this logic. Instead they have to explicitly do the locking. There were apparent bugs in the conversion of nl80211_dump_wiphy() in that we were not dropping the RTNL mutex in all the return paths, and it seems we very much should be doing so. So I fixed that whilst handling the overlapping changes. To simplify the initial returns, I take the RTNL mutex after we try to allocate 'tb'. Signed-off-by: David S. Miller <davem@davemloft.net>
| * qmi_wwan/cdc_ether: let qmi_wwan handle the Huawei E1820Bjørn Mork2013-06-112-0/+7
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Another QMI speaking Qualcomm based device, which should be driven by qmi_wwan, while cdc_ether should ignore it. Like on other Huawei devices, the wwan function can appear either as a single vendor specific interface or as a CDC ECM class function using separate control and data interfaces. The ECM control interface protocol is 0xff, likely in an attempt to indicate that vendor specific management is required. In addition to the near standard CDC class, Huawei also add vendor specific AT management commands to their firmwares. This is probably an attempt to support non-Windows systems using standard class drivers. Unfortunately, this part of the firmware is often buggy. Linux is much better off using whatever native vendor specific management protocol the device offers, and Windows uses, whenever possible. This means QMI in the case of Qualcomm based devices. The E1820 has been verified to work fine with QMI. Matching on interface number is necessary to distiguish the wwan function from serial functions in the single interface mode, as both function types will have class/subclass/function set to ff/ff/ff. The control interface number does not change in CDC ECM mode, so the interface number matching rule is sufficient to handle both modes. The cdc_ether blacklist entry is only relevant in CDC ECM mode, but using a similar interface number based rule helps document this as a transfer from one driver to another. Other Huawei 02/06/ff devices are left with the cdc_ether driver because we do not know whether they are based on Qualcomm chips. The Huawei specific AT command management is known to be somewhat hardware independent, and their usage of these class codes may also be independent of the modem hardware.

* sierra_net: keep status interrupt URB activeDan Williams2013-05-081-7/+31
| | | | | | | | | | | | | | | | The driver and firmware sync up through SYNC messages, and the firmware's affirmative reply to these SYNC messages appears to be the "Reset" indication received via the status interrupt endpoint. Thus the driver needs the status interrupt endpoint always active so that the Reset indication can be received even if the netdev is closed, which is the case right after device insertion. If the Reset indication is not received by the driver, it continues sending SYNC messages to the firmware, which crashes about 10 seconds later and the device stops responding.

* usbnet: allow status interrupt URB to always be activeDan Williams2013-05-081-6/+71
| | | | | | | | | | | | | | | | | | | | | Some drivers (sierra_net) need the status interrupt URB active even when the device is closed, because they receive custom indications from firmware. Add functions to refcount the status interrupt URB submit/kill operation so that sub-drivers and the generic driver don't fight over whether the status interrupt URB is active or not. A sub-driver can call usbnet_status_start() at any time, but the URB is only submitted the first time the function is called. Likewise, when the sub-driver is done with the URB, it calls usbnet_status_stop() but the URB is only killed when all users have stopped it. The URB is still killed and re-submitted for suspend/resume, as before, with the same refcount it had at suspend.

Call Trace: <IRQ> [<ffffffff8126f86d>] ? skb_release_all+0x9/0x1e [<ffffffff8126f8ad>] ? __kfree_skb+0x9/0x6f [<ffffffffa00b4200>] ? asix_rx_fixup_internal+0xff/0x1ae [asix] [<ffffffffa00fb3dc>] ? usbnet_bh+0x4f/0x226 [usbnet] ... It is easily reproducable by setting an MTU of 512 e. g. and sending something like ping -s 1472 -c 1 -M do $SELF from another box. And this is because the rx->ax_skb is freed on error, but rx->ax_skb is not reset, and the size is not reset to zero in this case. And since the skb is added again to the usbnet->done skb queue it is accessing already freed memory, resulting in the BUG when freeing a 2nd time. I therefore think the value 0x0000004000000001 show in the trace is more or less random data. Signed-off-by: Holger Eitzenberger <holger@eitzenberger.org> Signed-off-by: David S.

| | | | | | | | | | | | | | | | | | | | | | | | Pegasus driver used single callback for sync and async control URBs. Special flags were employed to distinguish between both, but due to flawed logic it didn't always work. As a result of this change [get|set]_registers() are now much simpler. Async write is also leaner and does not use single, statically allocated memory for usb_ctrlrequest, which is another potential race when asynchronously submitting URBs.

The be2net driver had a bug fix in 'net' that overlapped with the VLAN interface changes by Patrick McHardy in net-next. An IGB conflict existed because in 'net' the build_skb() support was reverted, and in 'net-next' there was a comment style fix within that code. Several batman-adv conflicts were resolved by making sure that all calls to batadv_is_my_mac() are changed to have a new bat_priv first argument. Eric Dumazet's TS ECR fix in TCP in 'net' conflicted with the F-RTO rewrite in 'net-next', mostly overlapping changes.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Add a protocol argument to the VLAN packet tagging functions. In case of HW tagging, we need that protocol available in the ndo_start_xmit functions, so it is stored in a new field in the skb. The new field fits into a hole (on 64 bit) and doesn't increase the sks's size. Signed-off-by: Patrick McHardy <kaber@trash.net> Signed-off-by: David S. Miller <davem@davemloft.net>

Two adavantages may be obtained with stopping bulk transfer after link becomes off: - USB bus bandwidth is saved(USB bus is shared bus except for USB3.0), for example, lots of 'IN' token packets and 'NYET' handshake packets is transfered on 2.0 bus. - probabaly power might be saved for usb host controller since cancelling bulk transfer may disable the asynchronous schedule of host controller. With this patch, when link becomes off, about ~10% performance boost can be found on bulk transfer of anther usb device which is attached to same bus with the usbnet device, see below test on next-20130410: - read from usb mass storage(Sandisk Extreme USB 3.0) on pandaboard with below command after unplugging ethernet cable: dd if=/dev/sda iflag=direct of=/dev/null bs=1M count=800 - without the patch 1, 838860800 bytes (839 MB) copied, 36.2216 s, 23.2 MB/s 2, 838860800 bytes (839 MB) copied, 35.8368 s, 23.4 MB/s 3, 838860800 bytes (839 MB) copied, 35.823 s, 23.4 MB/s 4, 838860800 bytes (839 MB) copied, 35.937 s, 23.3 MB/s 5, 838860800 bytes (839 MB) copied, 35.7365 s, 23.5 MB/s average: 23.6MB/s - with the patch 1, 838860800 bytes (839 MB) copied, 32.3817 s, 25.9 MB/s 2, 838860800 bytes (839 MB) copied, 31.7389 s, 26.4 MB/s 3, 838860800 bytes (839 MB) copied, 32.438 s, 25.9 MB/s 4, 838860800 bytes (839 MB) copied, 32.5492 s, 25.8 MB/s 5, 838860800 bytes (839 MB) copied, 31.6178 s, 26.5 MB/s average: 26.1MB/s Signed-off-by: Ming Lei <ming.lei@canonical.com> Signed-off-by: David S.
