net: lwip: add DHCP support and dhcp commmand

2024-10-16T17:11:56Z

Add what it takes to enable NETDEVICES with NET_LWIP and enable DHCP as well as the dhcp command. CMD_TFTPBOOT is selected by BOOTMETH_EFI due to this code having an implicit dependency on do_tftpb(). Note that PXE is likely non-fonctional with NET_LWIP (or at least not 100% functional) because DHCP option 209 is not supported by the lwIP library. Therefore, BOOTP_PXE_DHCP_OPTION cannot be enabled. Signed-off-by: Jerome Forissier Tested-by: Ilias Apalodimas Acked-by: Ilias Apalodimas

net: split net into net{,-common,-legacy,-lwip}

2024-10-16T17:11:56Z

Make net.h a wrapper which includes net-common.h and either net-legacy.h or net-lwip.h based on NET_LWIP. The function copy_filename() can be useful when NET_LWIP is enabled, therefore move it out of net/net.c which is built only when networking choice is NET and create a new file net/net-common.c.

net: introduce alternative implementation as net/lwip/

2024-10-16T17:11:56Z

Prepare the introduction of the lwIP (lightweight IP) TCP/IP stack by adding a new net/lwip/ directory and the NET_LWIP symbol. Network support is either NO_NET, NET (legacy stack) or NET_LWIP. Subsequent commits will introduce the lwIP code, re-work the NETDEVICE integration and port some of the NET commands and features to lwIP. SPL_NET cannot be enabled when NET_LWIP=y. SPL_NET pulls some symbols that are part of NET (such as arp_init(), arp_timeout_check(), arp_receive(), net_arp_wait_packet_ip()). lwIP support in SPL may be added later. Similarly, DFU_TFTP and FASTBOOT are not compatible with NET_LWIP because of dependencies on net_loop(), tftp_timeout_ms, tftp_timeout_count_max and other NET things. Let's add a dependency on !NET_LWIP for now. SANDBOX can select NET_LWIP but doing so will currently disable the eth dm tests as well as the wget tests which have strong dependencies on the NET code. Other adjustments to Kconfig files are made to fix "unmet direct dependencies detected" for USB_FUNCTION_SDP and CMD_FASTBOOT when the default networking stack is set to NET_LWIP ("default NET_LWIP" instead of "default NET" in Kconfig). The networking stack is now a choice between NO_NET, NET and NET_LWIP. Therefore '# CONFIG_NET is not set' should be 'CONFIG_NO_NET=y'. Adjust the defconfigs accordingly.

global: Rename SPL_TPL_ to PHASE_

2024-10-11T17:44:48Z

Use PHASE_ as the symbol to select a particular XPL build. This means that SPL_TPL_ is no-longer set. Update the comment in bootstage to refer to this symbol, instead of SPL_ Signed-off-by: Simon Glass

global: Rename SPL_ to XPL_

net: Fix compiling SPL when fastboot is enabled

2023-10-18T00:50:52Z

When fastboot is enabled in U-Boot proper and SPL_NET is enabled, we will try to (unsuccessfully) reference it in SPL. Fix these linker errors by conditioning on SPL_UDP/TCP_FUNCTION_FASTBOOT. Signed-off-by: Sean Anderson Reviewed-by: Simon Glass Reviewed-by: Tom Rini

net: add fastboot TCP support

2023-05-05T21:48:44Z

Known limitations are 1. fastboot reboot doesn't work (answering OK but not rebooting) 2. flashing isn't supported (TCP transport only limitation) The command syntax is fastboot tcp Signed-off-by: Dmitrii Merkurev Cc: Ying-Chun Liu (PaulLiu) Cc: Simon Glass Сс: Joe Hershberger Сс: Ramon Fried Reviewed-by: Simon Glass

net: dhcp6: Add DHCPv6 (DHCP for IPv6)

2023-05-05T21:48:44Z

Adds DHCPv6 protocol to u-boot. Allows for address assignement with DHCPv6 4-message exchange (SOLICIT->ADVERTISE->REQUEST->REPLY). Includes DHCPv6 options required by RFC 8415. Also adds DHCPv6 options required for PXE boot. Possible enhancements: - Duplicate address detection on DHCPv6 assigned address - IPv6 address assignement through SLAAC - Sending/parsing other DHCPv6 options (NTP, DNS, etc...)

net: Remove eth_legacy.c

As there are no more non-DM_ETH cases for networking, remove this legacy file and update the Makefile to match current usage. Signed-off-by: Tom Rini

net: ping6: Add ping6 command

2022-12-05T17:47:16Z

Implement ping6 command to ping hosts using IPv6. It works the same way as an ordinary ping command. There is no ICMP request so it is not possible to ping our host. This patch adds options in Kconfig and Makefile to build ping6 command. Series-changes: 3 - Added structures and functions descriptions - Added to ping6_receive() return value instead of void Series-changes: 4 - Fixed structures and functions description style Signed-off-by: Viacheslav Mitrofanov Reviewed-by: Ramon Fried Reviewed-by: Simon Glass
