* USB-RNDIS: Send RNDIS state on disconnectingVitaly Kuzmichev2011-02-19-0/+36
| | | | | | | Add waiting for receiving Ethernet gadget state on the Windows host side before dropping pullup, but keep it for debug. Signed-off-by: Vitaly Kuzmichev <vkuzmichev@mvista.com>

* USB-CDC: handle interrupt after dropped pullupVitaly Kuzmichev2011-02-19-0/+7
| | | | | | | | | | | | Disconnecting USB gadget with pending interrupt may cause its wrong handling in the next time when interface will be started again (especially actual for RNDIS). This interrupt may force the gadget to queue unexpected response before setup stage. Despite the fact that such interrupt handled after dropped pullup also may add pending response, this will not bring to any issues due to usb_ep_disable (which clears the queue) called on gadget unregistering.

* USB-CDC: Move MAC addresses setting into usb_eth_initVitaly Kuzmichev2011-01-19-36/+26
| | | | | | | This allows to change device and host MAC addresses without performing reset. Signed-off-by: Vitaly Kuzmichev <vkuzmichev@mvista.com>
* USB-CDC: Do not rename netdev after its registrationVitaly Kuzmichev2011-01-19-3/+2
| | | | | | | Calling eth_bind at usb_eth_init time causes renaming of the network device from 'usb_ether' to 'usb0'. Fixing this to keep the first name. Signed-off-by: Vitaly Kuzmichev <vkuzmichev@mvista.com>
* usb_ether: register usb ethernet gadget at each eth initLei Wen2011-01-19-4/+8
| | | | | | | | | | | | Since the ether may not be the only one usb gadget would be used in the uboot, it is neccessary to do the register each time the eth begin to work to make usb gadget driver less confussed when we want to use two different usb gadget at the same time. Usb gadget driver could simple ignore the register operation, if it find the driver has been registered already. Signed-off-by: Lei Wen <leiwen@marvell.com>
* Switch from archive libraries to partial linkingSebastien Carlier2010-11-17-2/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | Before this commit, weak symbols were not overridden by non-weak symbols found in archive libraries when linking with recent versions of binutils. As stated in the System V ABI, "the link editor does not extract archive members to resolve undefined weak symbols". This commit changes all Makefiles to use partial linking (ld -r) instead of creating library archives, which forces all symbols to participate in linking, allowing non-weak symbols to override weak symbols as intended. This approach is also used by Linux, from which the gmake function cmd_link_o_target (defined in config.mk and used in all Makefiles) is inspired. The name of each former library archive is preserved except for extensions which change from ".a" to ".o". This commit updates references accordingly where needed, in particular in some linker scripts. This commit reveals board configurations that exclude some features but include source files that depend these disabled features in the build, resulting in undefined symbols. Known such cases include: - disabling CMD_NET but not CMD_NFS; - enabling CONFIG_OF_LIBFDT but not CONFIG_QE. Signed-off-by: Sebastien Carlier <sebastien.carlier@gmail.com>

* USB-CDC: Prevent rx_req being enqueued twiceVitaly Kuzmichev2010-10-13-0/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | After gadget reinitializaton (after tftp has been done once) packet_received may become equal to 1 due to nuking OUT_EP while disabling it in eth_reset_config. rx_submit called from usb_eth_init queues rx_req first time. But the first call of usb_eth_recv from NetLoop queues rx_req again due to packet_received = 1. The following flow shows the path of functions calls when this happens: net/net.c:NetLoop | +-net/eth.c:eth_init | ether.c:usb_eth_init | | | +-udc_driver:usb_gadget_handle_interrupts | | udc_driver:... | | ether.c:eth_setup | | ether.c:eth_set_config | | ether.c:eth_reset_config | | udc_driver:usb_ep_disable | | udc_driver:nuke | | ether.c:rx_complete | | ether.c: packet_received = 1; | | | +-ether.c:rx_submit | udc_driver:usb_ep_queue --- The first time when rx_req is queued | +-net/eth.c:eth_rx ether.c:usb_eth_recv | +-udc_driver:usb_gadget_handle_interrupts | udc_driver:... --- no interrupts, returning +-ether.c: if (packet_received) { ... ether.c:rx_submit udc_driver:usb_ep_queue --- The second time!

* USB-CDC: Fix tx/rx_req memory leaksVitaly Kuzmichev2010-10-13-13/+7
| | | | | | | | | | | | Remove and fix needless and destructive operations with tx/rx_req. 1) 'req' in rx_complete is always not NULL and always equals to rx_req 2) Free allocated tx_req if rx_req allocation has failed 3) Do not zero out tx/rx_req in usb_eth_init, leave this for eth_reset_config which will be called at the next use of usb0 4) Additional check in usb_eth_recv is not required Signed-off-by: Vitaly Kuzmichev <vkuzmichev@mvista.com>

* USB-CDC: called handle_interrupts inside usb_eth_sendStefano Babic2010-09-20-1/+9
| | | | | | | | | The patch removes an endless loop in the usb_eth_send if the tx_complete is not called before going in the loop. The driver interrupt routine is called allowing the driver to check if the TX is completed. Signed-off-by: Stefano Babic <sbabic@denx.de>
* USB-CDC: correct wrong alignment in ether.cStefano Babic2010-09-20-1/+1
| | | | | | | | The buffer for the status request must be word aligned because it is accessed with 32 bit pointer in the eth_status_complete function. Signed-off-by: Stefano Babic <sbabic@denx.de>
* USB-CDC: change simple_strtol to simple_strtoulVitaly Kuzmichev2010-09-20-1/+1
| | | | | | | | | | The patch is based on commit bb9496c6f7e853e5d4edd5397c9d45f1968d623c (done by Julia Lawall <julia@diku.dk>) from linux-2.6.git. Since num is unsigned, it would seem better to use simple_strtoul that simple_strtol. Signed-off-by: Vitaly Kuzmichev <vkuzmichev@mvista.com>
* USB-CDC: ethernet error path potential oops fixVitaly Kuzmichev2010-09-20-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Fix potential oops on rare error path. The patch is based on commit e7b13ec9235b9fded90f826ceeb8c34548631351 (done by David Brownell <david-b@pacbell.net>) from linux-2.6.git. Description of the issue taken from linux kernel bugzilla: (https://bugzilla.kernel.org/show_bug.cgi?id=9594) The potential error can be tracked down as follows: (1) line 807: let the second conjunct on the "if" statment be false meaning "dev->status_ep" is null. This means the "if" evaluates to false. follow thru the code until... (2) line 808: usb_ep_disable(dev->status_ep) passes in a null argument, however "usb_ep_disable" cannot handle that: (from include/linux/usb/gadget.h) 191 static inline int 192 usb_ep_disable (struct usb_ep *ep) 193 { 194 return ep->ops->disable (ep); 195 } -- Signed-off-by: Vitaly Kuzmichev <vkuzmichev@mvista.com>
