usb: gadget: ether: return error from rx_submit if no request

2013-10-20T21:42:39Z

This prevents a crash if tftpboot is given a bad filename. rx_req will be released by eth_reset_config which is called by eth_disconnect, which is called using the .disconnect member of usb_gadget_driver by mv_pullup in mv_udc which is called using the .pullup member of usb_gadget_ops by usb_gadget_disconnect which is called by usb_eth_halt which is called using the .halt member of eth_device by eth_halt which is called by TftpHandler when TFTP_ERR_FILE_NOT_FOUND or TFTP_ERR_ACCESS_DENIED occurs I trigger this with the following commands setenv ipaddr 10.0.0.2 && setenv netmask 255.255.255.0 && setenv serverip 10.0.0.1 setenv usbnet_devaddr 00:11:22:33:44:55 && setenv usbnet_hostaddr 00:aa:bb:cc:dd:ee setenv ethprime usb_ether && setenv ethact usb_ether && setenv ncip 10.0.0.1 tftpboot 10800000 10.0.0.1:missing_file Signed-off-by: Troy Kisky

usb: gadget: ether set wMaxPacketSize

2013-10-20T21:42:39Z

set wMaxPacketSize for full speed descriptors fs_source_desc, fs_sink_desc to 64. Full-speed bulk endpoint can have a maximum packet size of 8, 16, 32, or 64 bytes, so choice 64. The hs_source_desc, hs_sink_desc, already have their wMaxPacketSize set to 512. That is the only legal value for high speed bulk endpoints. Strictly speaking, this patch is not needed because usb_ep_autoconfig will call ep_matches which will override wMaxPacketSize for BULK endpoints only with the size associated with the endpoint setup by the udc driver. But if you want to rely on this, you may as well combine the full speed descriptor with the high speed descriptor to minimize confusion. Signed-off-by: Troy Kisky

usb: gadget: Fix data aborts during USB ethernet boot

2013-09-24T15:51:34Z

As seen on GCC 4.6 Linaro compiler, control_req buffer is not aligned on 4 byte boundaray causing data aborts in eth_setup -> conf_buf during dhcp boot over usb_ether. Fix the issue my aligning control_req buffer using DEFINE_CACHE_ALIGN_BUFFER. Tested on am335x_evm platform (beaglebone). Applies on 2013.10-rc1 branch.

usb gadget ether: Fix warning in is_eth_addr_valid()

2012-11-04T18:00:38Z

The gadget ethernet driver needs to keep copies of the MAC address (at both endpoints) as strings so it needs a custom function for validation of the MAC. It was not however performing a totally correct check and also was emitting a warning about a set but unused variable. The solution to both is that after checking the string contents we use the standard test for a valid MAC. Cc: Joe Hershberger Cc: Marek Vasut Signed-off-by: Tom Rini Acked-by: Joe Hershberger

usbether: Removed DEV_CONFIG_{CDC,SUBSET}

2012-10-15T18:54:01Z

Removed DEV_CONFIG_CDC and DEV_CONFIG_SUBSET and replaced it with CONFIG_USB_ETH_CDC and CONFIG_USB_ETH_SUBSET. Signed-off-by: Lukasz Dalek

usbether: Define CONFIG_USB_ETH_{CDC,SUBSET}

2012-10-15T18:54:01Z

Introduced CONFIG_USB_ETH_CDC and CONFIG_USB_ETH_SUBSET as preparation for removal DEV_CONFIG_CDC and DEV_CONFIG_SUBSET Signed-off-by: Lukasz Dalek

usbether: Fixed bug when using with PXA25X chips

2012-10-15T18:54:01Z

PXA25X chips don't support alternate settings so driver uses non-CDC driver. But only code defined between DEV_CONFIG_CDC signals that network is up. This patch is fixing this bug by signaling that network is up after USB SET_INTERFACE request. Signed-off-by: Lukasz Dalek

net: Fix remaining API interface breakage

2012-05-23T19:19:21Z

These are all the files which use the API incorrectly but did not get built using MAKEALL -a powerpc|arm. I have no compiler for them, but the remaining issues should be far less than without this patch. Any outstanding issues are left to the maintainers of boards that use these drivers.
