2013-03-03ax88179_178a: ASIX AX88179_178A USB 3.0/2.0 to gigabit ethernet adapter driverFreddy Xin3-0/+1467
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. This driver had been verified on x86 system with AX88179/AX88178A and Sitcomm LN-032 USB dongles. Signed-off-by: Freddy Xin <freddy@asix.com.tw> Signed-off-by: David S. Miller <davem@davemloft.net>
2013-02-27usb/net/asix_devices: Add USBNET HG20F9 ethernet dongleGlen Turner1-0/+31
This USB ethernet adapter was purchased in anodyne packaging from the computer store adjacent to linux.conf.au 2013 in Canberra (Australia). 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.

2013-02-14net: cdc_ncm: fix probing of devices with multiple control interface altsettingsBjørn Mork1-3/+8
commit bd329e1 ("net: cdc_ncm: do not bind to NCM compatible MBIM devices") added a test for a CDC MBIM altsetting, implementing the cdc_ncm part of MBIM backward compatibility support. This intentionally made the driver behave differently for CDC NCM devices with 2 alternate settings for the Communication interface, depending on whether or not CONFIG_USB_NET_CDC_MBIM was enabled. This is correct iff alternate setting #1 really *is* a MBIM setting. If not, then NCM probing will use a different altsetting than before, possibly causing probing failures depending on CONFIG_USB_NET_CDC_MBIM. Fix by setting the altsetting back to default after the test, restoring the previous behaviour for non MBIM devices. This bug causes probing of Huawei E3276 devices to fail when the MBIM driver is enabled, because these devices have a second alternate setting with no CDC functional descriptors.

2013-02-04net: usbnet: fix tx_dropped statisticsBjørn Mork1-6/+4
It is normal for minidrivers accumulating frames to return NULL from their tx_fixup function. We do not want to count this as a drop, or log any debug messages. A different exit path is therefore chosen for such drivers, skipping the debug message and the tx_dropped increment. The test for accumulating drivers was however completely bogus, making the exit path selection depend on whether the user had enabled tx_err logging or not. This would arbitrarily mess up accounting for both accumulating and non-accumulating minidrivers, and would result in unwanted debug messages for the accumulating drivers. Fix by testing for FLAG_MULTI_PACKET instead, which probably was the intention from the beginning. This usage match the documented behaviour of this flag: Indicates to usbnet, that USB driver accumulates multiple IP packets. Affects statistic (counters) and short packet handling.

2013-01-23net: cdc_mbim: send ZLP only for the specific buggy deviceBjørn Mork1-0/+19
Reverting 328d7b8 and instead adding an exception for the Sierra Wireless MC7710. commit 328d7b8 (net: cdc_mbim: send ZLP after max sized NTBs) added a workaround for an issue observed on one specific device. Concerns were raised that this workaround adds a performance penalty to all devices based on questionable, if not buggy, behaviour of a single device: "If you add ZLP for NTBs of dwNtbOutMaxSize, you are heavily affecting CPU load, increasing interrupt load by factor of 2 in high load traffic scenario and possibly decreasing throughput for all other devices which behaves correctly." "The idea of NCM was to avoid extra ZLPs. If your transfer is exactly dwNtbOutMaxSize, it's known, you can submit such request on the receiver side and you do not need any EOT indicatation, so the frametime can be used for useful data." Adding a device specific exception to prevent the workaround from affecting well behaved devices. The assumption here is that needing a ZLP is truly an *exception*. We do not yet have enough data to verify this. The generic workaround in commit 328d7b8 should be considered acceptable despite the performance penalty if the exception list becomes a maintainance hassle.

2013-01-21net: cdc_mbim: send ZLP after max sized NTBsBjørn Mork1-1/+1
We normally avoid sending ZLPs by padding NTBs with a zero byte if the NTB is shorter than dwNtbOutMaxSize, resulting in a short USB packet instead of a ZLP. But in the case where the NTB length is exactly dwNtbOutMaxSize and this is an exact multiplum of wMaxPacketSize, then we must send a ZLP. This fixes an issue seen on a Sierra Wireless MC7710 device where the transmission would fail whenever we ended up padding the NTBs to max size.

2013-01-21net: cdc_ncm: workaround for missing CDC UnionBjørn Mork1-0/+27
Adding support for the MBIM mode in some Sierra Wireless devices. Some Sierra Wireless firmwares support CDC MBIM but have no CDC Union funtional descriptor. This violates the MBIM specification, but we can easily work around the bug by looking at the Interface Association Descriptor instead. This is most likely what Windows uses too, which explains how the firmware bug has gone unnoticed until now. This change will not affect any currently supported device conforming to the NCM or MBIM specifications, as they must have the CDC Union descriptor.

2013-01-18tty: Added a CONFIG_TTY option to allow removal of TTYJoe Millenbach1-2/+2
The option allows you to remove TTY and compile without errors. This saves space on systems that won't support TTY interfaces anyway. bloat-o-meter output is below. The bulk of this patch consists of Kconfig changes adding "depends on TTY" to various serial devices and similar drivers that require the TTY layer. Ideally, these dependencies would occur on a common intermediate symbol such as SERIO, but most drivers "select SERIO" rather than "depends on SERIO", and "select" does not respect dependencies. bloat-o-meter output comparing our previous minimal to new minimal by removing TTY. The list is filtered to not show removed entries with awk '$3 != "-"' as the list was very long. add/remove: 0/226 grow/shrink: 2/14 up/down: 6/-35356 (-35350) function old new delta chr_dev_init 166 170 +4 allow_signal 80 82 +2 static.__warned 143 142 -1 disallow_signal 63 62 -1 __set_special_pids 95 94 -1 unregister_console 126 121 -5 start_kernel 546 541 -5 register_console 593 588 -5 copy_from_user 45 40 -5 sys_setsid 128 120 -8 sys_vhangup 32 19 -13 do_exit 1543 1526 -17 bitmap_zero 60 40 -20 arch_local_irq_save 137 117 -20 release_task 674 652 -22 static.spin_unlock_irqrestore 308 260 -48 Signed-off-by: Joe Millenbach <jmillenbach@gmail.com> Reviewed-by: Jamey Sharp <jamey@minilop.net> Reviewed-by: Josh Triplett <josh@joshtriplett.org> Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>

In two places, tmp is initialized implicitly by being passed as a pointer during a function call. However, this is not obvious to the compiler, which logs a warning.

2013-01-15TTY: switch tty_flip_buffer_pushJiri Slaby1-16/+15
Now, we start converting tty buffer functions to actually use tty_port. This will allow us to get rid of the need of tty in many call sites. Only tty_port will needed and hence no more tty_port_tty_get in those paths. Now, the one where most of tty_port_tty_get gets removed: tty_flip_buffer_push. IOW we also closed all the races in drivers not using tty_port_tty_get at all yet. Also we move tty_flip_buffer_push declaration from include/linux/tty.h to include/linux/tty_flip.h to all others while we are changing it anyway.

2013-01-14net: phy: remove flags argument from phy_{attach, connect, connect_direct}Florian Fainelli1-1/+1
The flags argument of the phy_{attach,connect,connect_direct} functions is then used to assign a struct phy_device dev_flags with its value. All callers but the tg3 driver pass the flag 0, which results in the underlying PHY drivers in drivers/net/phy/ not being able to actually use any of the flags they would set in dev_flags. This patch gets rid of the flags argument, and passes phydev->dev_flags to the internal PHY library call phy_attach_direct() such that drivers which actually modify a phy device dev_flags get the value preserved for use by the underlying phy driver.
