* 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.

* asix: fix BUG in receive path when lowering MTUholger@eitzenberger.org2013-05-031-0/+3
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | There is bug in the receive path of the asix driver at the time a packet is received larger than MTU size and DF bit set: BUG: unable to handle kernel paging request at 0000004000000001 IP: [<ffffffff8126f65b>] skb_release_head_state+0x2d/0xd2 ... 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.

| * drivers: net: usb: pegasus: fix control urb submissionPetko Manolov2013-04-292-217/+76
| | | | | | | | | | | | | | | | | | | | | | | | 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.

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.

It is likely a hardcoded firmware default. The circumstances where this bug has been observed indicates that the trigger is related to timing or some other factor the host cannot control. Repeating the exact same configuration sequence that caused it to trigger once, will not necessarily cause it to trigger the next time. Reproducing the bug is therefore difficult. This opens up a possibility that the bug is more common than we can confirm, because affected devices often will work properly again after a reset. A procedure most users are likely to try out before reporting a bug. Unconditionally rewriting the destination address if the first digit of the received packet is 0, is considered an acceptable compromise since we already have to inspect this digit. The simplification will cause unnecessary rewrites if the real address starts with 0, but this is still better than adding additional tests for this particular case.

* | | | net: qmi_wwan: fixup missing ethernet header (firmware bug workaround)Bjørn Mork2013-04-191-0/+84

The devices work as expected when attached to 2G or 3G networks, sending an ethernet header with all packets. This driver is not aware of which network the modem attached to, and even if it were there are still some packet types which are always received with the header intact. All devices supported by this driver have severely limited networking capabilities: - can only transmit IPv4, IPv6 and possibly ARP - can only support a single host hardware address at any time - will only do point-to-point communcation with the host Because of this, we are able to reliably identify any bogus raw IP packets by simply looking at the 4 IP version bits. All we need to do is to avoid 4 or 6 in the first digit of the mac address. This workaround ensures this, and fix up the received packets as necessary. Given the distribution of the bug, it is believed that the source is the chipset vendor. The devices which are verified to be affected are: Huawei E392u-12 (Qualcomm MDM9200) Pantech UML290 (Qualcomm MDM9600) Novatel USB551L (Qualcomm MDM9600) Novatel E362 (Qualcomm MDM9600) It is believed that the bug depend on firmware revision, which means that possibly all devices based on the above mentioned chipset may be affected if we consider all available firmware revisions. The information about affected devices and versions is likely incomplete. As the additional overhead for packets not needing this fixup is very small, it is considered acceptable to apply the workaround to all devices handled by this driver.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | commit bd329e1 ("net: cdc_ncm: do not bind to NCM compatible MBIM devices") introduced a new policy, preferring MBIM for dual NCM/MBIM functions if the cdc_mbim driver was enabled. This caused a regression for users wanting to use NCM. Devices implementing NCM backwards compatibility according to section 3.2 of the MBIM v1.0 specification allow either NCM or MBIM on a single USB function, using different altsettings. The cdc_ncm and cdc_mbim drivers will both probe such functions, and must agree on a common policy for selecting either MBIM or NCM. Until now, this policy has been set at build time based on CONFIG_USB_NET_CDC_MBIM. Use a module parameter to set the system policy at runtime, allowing the user to prefer NCM on systems with the cdc_mbim driver.

|/ | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | commit bd877e4 ("net: qmi_wwan: use a single bind function for all device types") made Gobi 1K devices fail probing. Using the number of endpoints in the default altsetting to decide whether the function use one or two interfaces is wrong. Other altsettings may provide more endpoints. With Gobi 1K devices, USB interface #3's altsetting is 0 by default, but altsetting 0 only provides one interrupt endpoint and is not sufficent for QMI. Altsetting 1 provides all 3 endpoints required for qmi_wwan and works with QMI. Gobi 1K layout for intf#3 is: Interface Descriptor: 255/255/255 bInterfaceNumber 3 bAlternateSetting 0 Endpoint Descriptor: Interrupt IN Interface Descriptor: 255/255/255 bInterfaceNumber 3 bAlternateSetting 1 Endpoint Descriptor: Interrupt IN Endpoint Descriptor: Bulk IN Endpoint Descriptor: Bulk OUT Prior to commit bd877e4, we would call usbnet_get_endpoints before giving up finding enough endpoints. Removing the early endpoint number test and the strict functional descriptor requirement allow qmi_wwan_bind to continue until usbnet_get_endpoints has made the final attempt to collect endpoints. This restores the behaviour from before commit bd877e4 without losing the added benefit of using a single bind function. The driver has always required a CDC Union functional descriptor for two-interface functions. Using the existence of this descriptor to detect two-interface functions is the logically correct method.

| | | | | | | | | | | | | | | | | | | | | | | | | | This is a resubmission. Added kfree() in ax88179_get_eeprom to prevent memory leakage. Modified "__le16 rxctl" to "u16 rxctl" in "struct ax88179_data" and removed pointless casts. Removed asix_init and asix_exit functions and added "module_usb_driver(ax88179_178a_driver)". Fixed endianness issue on big endian systems and verified this driver on iBook G4. Removed steps that change net->features in ax88179_set_features function. Added "const" to ethtool_ops structure and fixed the coding style of AX88179_BULKIN_SIZE array. Fixed the issue that the default MTU is not 1500. Added ax88179_change_mtu function and enabled the hardware jumbo frame function to support an MTU higher than 1500. Fixed indentation and empty line coding style errors. The _nopm version usb functions were added to access register in suspend and resume functions. Serveral variables allocted dynamically were removed and replaced by stack variables. ax88179_get_eeprom were modified from asix_get_eeprom in asix_common. This patch adds a driver for ASIX's AX88179 family of USB 3.0/2.0 to gigabit ethernet adapters. It's based on the AX88xxx driver but the usb commands used to access registers for AX88179 are completely different.

A web search shows other recent purchasers in Lancaster (UK) and Seattle (USA). Just like an emergent virus, our age of e-commerce and airmail allows underdocumented hardware to spread around the world instantly using the vector of ridiculously low prices. Paige Thompson, infected via eBay, discovered that the HG20F9 is a copy of the Asix 88772B; many viruses copy the RNA of other viruses. See Paige's work at <https://github.com/paigeadele/HG20F9>. This patch uses her discovery to update the restructured Asix driver in the current kernel. Just as some viruses inhabit seemingly-healthy cells, the HG20F9 uses the Vendor ID 0x066b assigned to Linksys Inc. For the present there is no clash of Product ID 0x20f9.
