2021-09-28net: dsa: ensure port names are NULL-terminated after DSA_PORT_NAME_LENGTH ↵Vladimir Oltean1-2/+2
truncation strncpy() simply bails out when copying a source string whose size exceeds the destination string size, potentially leaving the destination string unterminated. One possible way to address is to pass DSA_PORT_NAME_LENGTH - 1 and a previously zero-initialized destination string, but this is more difficult to maintain. The chosen alternative is to use strlcpy(), which properly limits the copy len in the (srclen >= size) case to "size - 1", and which is also more efficient than the strncpy() byte-by-byte implementation by using memcpy. The destination string returned by strlcpy() is always NULL terminated. Signed-off-by: Vladimir Oltean <vladimir.oltean@nxp.com> Reviewed-by: Ramon Fried <rfried.dev@gmail.com>

2021-06-18net: use the same alias stem for ethernet as linuxMichael Walle1-2/+2
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.

2021-04-15net: phy: fixed: Be compatible with live OF treeVladimir Oltean1-2/+4
On systems that use CONFIG_OF_LIVE, the "ofnode" type is defined as const struct device_node *np, while on the flat DT systems it is defined as a long of_offset into gd->fdt_blob. It is desirable that the fixed PHY driver uses the higher-level ofnode abstraction instead of parsing gd->fdt_blob directly, because that enables it to work on live OF systems. The fixed PHY driver has used a nasty hack since its introduction in commit db40c1aa1c10 ("drivers/net/phy: add fixed-phy / fixed-link support"), which is to pass the long gd->fdt_blob offset inside int phydev->addr (a value that normally holds the MDIO bus address at which the PHY responds). Even ignoring the fact that the types were already mismatched leading to a potential truncation (flat OF offset was supposed to be a long and not an int), we really cannot extend this hack any longer, because there's no way an int will hold the other representation of ofnode, the struct device_node *np. So we unfortunately need to do the right thing, which is to use the framework introduced by Grygorii Strashko in commit eef0b8a930d1 ("net: phy: add ofnode node to struct phy_device"). This will populate phydev->node for the fixed PHY. Note that phydev->node will not be valid in the probe function, since that is called synchronously from phy_device_create and we really have no way of passing the ofnode directly through the phy_device_create API. So we do what other drivers do too: we move the OF parsing logic from the .probe to the .config method of the PHY driver. The new function will be called at phy_config() time. I do believe I've converted all the possible call paths for creating a PHY with PHY_FIXED_ID, so there is really no reason to maintain compatibility with the old logic of retrieving a flat OF tree offset from phydev->addr. We just pass 0 to phydev->addr now.

2021-02-21mdio-uclass.c: support fixed-link subnodesRasmus Villemoes1-0/+7
When trying to port our mpc8309-based board to DM_ETH, on top of Heiko's patches, I found that nothing in mdio-uclass.c seems to support the use of a fixed-link subnode of the ethernet DT node. That is, the ethernet node looks like enet0: ethernet@2000 { device_type = "network"; compatible = "ucc_geth"; ... fixed-link { reg = <0xffffffff>; speed = <100>; full-duplex; }; but the current code expects there to be phy-handle property. Adding that, i.e. phy-handle = <&enet0phy>; enet0phy: fixed-link { just makes the code break a few lines later since a fixed-link node doesn't have a reg property. Ignoring the dtc complaint and adding a dummy reg property, we of course hit "can't find MDIO bus for node ethernet@2000" since indeed, the parent node of the phy node does not represent an MDIO bus. So that's obviously the wrong path. Now, in linux, it seems that the fixed link case is treated specially; in the of_phy_get_and_connect() which roughly corresponds to dm_eth_connect_phy_handle() we have if (of_phy_is_fixed_link(np)) { ret = of_phy_register_fixed_link(np); ... } else { phy_np = of_parse_phandle(np, "phy-handle", 0); ... } phy = of_phy_connect(dev, phy_np, hndlr, 0, iface); And U-Boot's phy_connect() does have support for fixed-link subnodes. Calling phy_connect() directly with NULL bus and a dummy address does seem to make the ethernet work.

2021-01-19net: Do not respond to ICMP_ECHO_REQUEST if we do not have an IP addressDavid Rivshin1-0/+3
While doing DHCP the interface IP is set to 0.0.0.0. This causes the check in net.c on dst_ip to be effectively skipped, and all IP datagrams are accepted up the IP stack. In the case of an ICMP_ECHO_REQUEST for the matching MAC address (regardless of destination IP), the result is that an ICMP_ECHO_REPLY is sent. The source address of the ICMP_ECHO_REPLY is 0.0.0.0, which is an illegal source address. This can happen in common practice with the following sequence: DHCP (U-Boot or OS) acquires IP address 10.0.0.1 System reboots U-Boot starts DHCP and send DHCP DISCOVER DHCP server decides to OFFER 10.0.0.1 again (perhaps because of existing lease or manual configuration) DHCP server tries to PING 10.0.0.1 to see if anyone is squatting on it DHCP server still has our MAC address in its ARP table for 10.0.0.1 U-Boot receives PING, and responds with an illegal source address This may further result in a the DHCP server seeing the response as confirmation that someone is squatting on 10.0.0.1, and picking a new IP address from the pool to try again Signed-off-by: David Rivshin <drivshin@allworx.com>

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.

2020-10-10net: Expose some errors generated in net_initSean Anderson2-4/+14
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.
