2024-05-15net: eth-uclass: guard against reentrant eth_init()/eth_halt() callsMatthias Schiffer
With netconsole, any log message can result in an eth_init(), possibly causing an reentrant call into eth_init() if a driver's ops print anything: eth_init() -> driver.start() -> printf() -> netconsole -> eth_init() eth_halt() -> driver.stop() -> printf() -> netconsole -> eth_init() Rather than expecting every single Ethernet driver to handle this case, prevent the reentrant calls in eth_init() and eth_halt(). The issue was noticed on an AM62x board, where a bootm after simultaneous netconsole and TFTP would result in a crash.

2022-10-17net: eth-uclass: Do not set device on errorMichal Suchanek
eth_get_dev relies on the broken behavior that returns an error but not the device on which the error happened which gives the caller no reasonable way to report or handle the error. In a later patch uclass_first_device_err will be changed to return the device on error but eth_get_dev stores the returned device pointer directly in a global state without checking the return value.

2022-10-17dm: treewide: Use uclass_first_device_err when accessing one deviceMichal Suchanek
There is a number of users that use uclass_first_device to access the first and (assumed) only device in uclass. Some check the return value of uclass_first_device and also that a device was returned which is exactly what uclass_first_device_err does. Some are not checking that a device was returned and can potentially crash if no device exists in the uclass. Finally there is one that returns NULL on error either way. Convert all of these to use uclass_first_device_err instead, the return value will be removed from uclass_first_device in a later patch.

2021-06-18net: use the same alias stem for ethernet as linuxMichael Walle
Linux uses the prefix "ethernet" whereas u-boot uses "eth". This is from the linux tree: $ grep "eth[0-9].*=.*&" arch/**/*dts{,i}|wc -l 0 $ grep "ethernet[0-9].*=.*&" arch/**/*dts{,i}|wc -l 633 In u-boot device trees both prefixes are used. Until recently the only user of the ethernet alias was the sandbox test device tree. This changed with commit fc054d563bfb ("net: Introduce DSA class for Ethernet switches"). There, the MAC addresses are inherited based on the devices sequence IDs which is in turn given by the device tree. Before there are more users in u-boot and both worlds will differ even more, rename the alias prefix to "ethernet" to match the linux ones. Also adapt the test cases and rename any old aliases in the u-boot device trees.

2021-01-19net: eth-uclass: avoid running start() twice without stop()Matthias Schiffer
Running the start() handler twice without a stop() inbetween completely breaks communication for some ethernet drivers like fec_mxc. eth_halt() is called before each eth_init(). Due to the switch to eth_is_active() in commit 68acb51f442f ("net: Only call halt on a driver that has been init'ed"), this is not sufficient anymore when netconsole is active: eth_init_state_only()/eth_halt_state_only() manipulate the state check that is performed by eth_is_active() without actually calling into the driver. The issue can be triggered by starting a network operation (e.g. ping or tftp) while netconsole is active. Add an additional "running" flag that reflects the actual state of the driver and use it to ensure that eth_halt() actually stops the device as it is supposed to.

This construct is quite long-winded. In earlier days it made some sense since auto-allocation was a strange concept. But with driver model now used pretty universally, we can shorten this to 'auto'.

2020-10-10net: Expose some errors generated in net_initSean Anderson
net_init does not always succeed, and there is no existing mechanism to discover errors. This patch allows callers of net_init (such as net_init) to handle errors. The root issue is that eth_get_dev can fail, but net_init_loop doesn't expose that. The ideal way to fix eth_get_dev would be to return an error with ERR_PTR, but there are a lot of callers, and all of them just check if it's NULL. Another approach would be to change the signature to something like int eth_get_dev(struct udevice **pdev) but that would require rewriting all of the many callers.

2020-05-10net: Add eth phy generic driver for shared MDIOYe Li
For dual ethernet controllers, the HW design may connect ETH phys to one MDIO ports. So two different ethernet drivers have to share MDIO bus. Since two ethernet drivers are independent, we can't ensure their probe order. To resolve this problem, introduce an eth phy generic driver and uclass. After eth-uclass binds, we search the mdio node and binds the phy node with the eth-phy-generic driver. When one eth driver get its phy device, the parent of phy device will probe prior than phy device. So this ensure the eth driver ownes the MDIO bus will be probed before using its MDIO.
