[PATCH v13 00/21] Introduce the lwIP network stack
This is a rework of a patch series by Maxim Uvarov: "net/lwip: add lwip library for the network stack" [1]. The goal is to introduce the lwIP TCP/IP stack [2] [3] as an alternative to the current implementation in net/, selectable with Kconfig, and ultimately keep only lwIP if possible. Some reasons for doing so are: - Make the support of HTTPS in the wget command easier. Javier T. and Raymond M. (CC'd) have some additional lwIP and Mbed TLS patches to do so. With that it becomes possible to fetch and launch a distro installer such as Debian etc. using a secure, authenticated connection directly from the U-Boot shell. Several use cases: * Authentication: prevent MITM attack (third party replacing the binary with a different one) * Confidentiality: prevent third parties from grabbing a copy of the image as it is being downloaded * Allow connection to servers that do not support plain HTTP anymore (this is becoming more and more common on the Internet these days) - Possibly benefit from additional features implemented in lwIP - Less code to maintain in U-Boot
Prior to applying this series, the lwIP stack needs to be added as a Git subtree with the following command:
$ git subtree add --squash --prefix lib/lwip/lwip \ https://github.com/lwip-tcpip/lwip.git STABLE-2_2_0_RELEASE
Notes
1. A number of features are currently incompatible with NET_LWIP: DFU_TFTP, FASTBOOT, SPL_NET, ETH_SANDBOX, ETH_SANDBOX_RAW, DM_ETH. They all make assumptions on how the network stack is implemented and/or pull sybols that are not trivially exported from lwIP. Some interface rework may be needed.
2. Due to the above, and in order to provide some level of testing of the lwIP code in CI even when the legacy NET is the default, a new QEMU configuration is introduced (qemu_arm64_lwip_defconfig) which is based on qemu_arm64_defconfig with NET_LWIP and CMD_*_LWIP enabled. In addition to that, this series has some [TESTING] patches which make NET_LWIP the default.

Changes in v13:
- Rebased onto master - "net: lwip: tftp: add support of blksize option to client": update computation of blksize_length (Ilias A.)
Changes in v12:
- Rebase onto master - Combine "net: split include/net.h into net{, -common, -legacy, -lwip}.h" and "net: move copy_filename() to new file net/net-common.c" (Ilias A.) - Fold "net-lwip: lwIP wget supports user defined port in the uri, so allow it." into parent patch "net-lwip: add wget command" - CI: update .gitlab-ci.yml too (Tom R.) - Fold "configs: replace '# CONFIG_NET is not set' with CONFIG_NO_NET=y" into "net: introduce alternative implementation as net-lwip/" - bootflow_cmd_label test: use 'if CONFIG_IS_ENABLED(DSA_SANDBOX)' - Drop the "[TESTING]" patches: * "[TESTING] Kconfig: enable NET_LWIP by default" * "[TESTING] configs: set CONFIG_NET=y for FTGMAC100" - Drop the patches sent separately: * "net: recv(): return -EAGAIN instead of 0 when no cleanup is expected" * "Make AVB_VERIFY depend on FASTBOOT" * "linker_lists: set LINKER_LIST_ALIGN to 8 if 64BIT" - Fix "configs: use syntax CONFIG_FOO=n in tools-only_defconfig": 'CONFIG_NET=n' was inadvertently forgotten. - Fix "net: introduce alternative implementation as net-lwip/": set CONFIG_NO_NET=y in tools-only_defconfig. - Add the "git subtree add" command to the patch description in "net-lwip: build lwIP". - All patches: use "net: lwip:" as a subsystem prefix rather than "net-lwip:". - Apply review tags
Changes in v11:
- Rebased onto next - "Miscellaneous fixes" removed (patches were merged in next). The series still begins with small fixes posted separately [1] [2] [3]. - Add (some) support for CMD_PXE and therefore drop patch "[TESTING] configs: set CONFIG_NET=y when PXE is enabled". This is build-tested only and it is very likely that some work is needed to make it useful. For example, adding the code for DHCP option 209 to lwIP so that BOOTP_PXE_DHCP_OPTION can be supported. - SANDBOX is now supported, but with the dm eth and wget tests disabled. - Move eth_set_enable_bootdevs() declaration to net-common.h Fixes warning with snow_defconfig: test/test-main.c:310:17: warning: implicit declaration of function ‘eth_set_enable_bootdevs’ [....] - Do eth_init() and eth_init_rings() only once, and do not forget lwip_init()! Fixes TFTP stalls on TI K3 (reported by Tom R. and tested by Ilias A.) - Set MEM_ALIGNMENT to 8 in lib/lwip/u-boot/lwipopts.h. Fixes TFTP random crashes on TI K3 (Ilias A.) - net_lwip_rx(): call free_pkt() even when recv() has returned 0, as required by the driver model documentation (and imx8mp_evk). Fixes a regression introduced in v9. Goes together with patch [2]. - Add "lwip: tftp: bind to TFTP port only when in server mode" to fix an issue with interrupted tftp commands (the tftp command hangs if it is interrupted with Ctrl-C and started again). - TFTP: fix uninitialized "ret" variable in do_tftpb(); print "Abort" on Ctrl-C. - MAINTAINERS: remove README and add sandbox ethernet driver to the list of maintained files. - AFAICT, CI should be all good except qemu_xtensa_dc233c which is broken when NET_LWIP=y (QEMU just hangs with no output). I could not find or build a suitable GDB binary to debug that.

Changes in v10:
- Rebase onto next - URL for lwIP changed in cover letter: using GitHub now since all tags have suddenly disappeared from the repository on gnu.org. - Post fixes as a separate series [1] or individual patches [2] [3] - Add "if NET_LWIP" to net/lwip/Kconfig to fix a kconfig warning when doing the full branch build with buildman ("[NEW]") - net/ is added to libs-y only when NET or NET_LWIP, not NO_NET - Apply review tags

Changes in v9:
- Rebased onto master, reordered commits to put some fixes that are not strictly related to lwIP first. - New commit "test/py: test_efi_loader: add missing dependency on cmd_tftpboot" (Tom R.) - test_efi_loader.py: add missing dependency on cmd_wget (Tom R.) - wget: fix divide by zero when transfer takes less than 1ms (Tom R.) - New commit "configs: use syntax CONFIG_FOO=n in tools-only_defconfig" (Tom R.) - Make TCP_WND configurable (via CONFIG_LWIP_TCP_WND) because a large value is needed for good performance especially with latency but transfers stall in QEMU (-net user) when the value is larger than a few KB (Anton A., offlist) - Added [TESTING] commits to run CI with NET_LWIP enabled by default except for SANDBOX and platforms that enable PXE, and fixed a number of issues: * coreboot_defconfig: 'implicit declaration' warnings on ip_checksum_ok() and compute_ip_checksum() * Fix EFI net tests (bootefi selftest) by adding missing push_packed() call to net_process_received_packet() * qemu_arm64: fix test_efi_loader.py failures (skip HTTP test by default since it needs a HTTP server; fix a bug in the dhcp command which would not set the "serverip" variable) * QEMU CI tests for r2dplus_i82557c, r2dplus_rtl8139: Fixed receive errors due to calling free_pkt() with a length of zero. r2dplus_tulip: fixed "dm_pci_phys_to_bus: invalid physical address" caused by too late eth_init_rings(). With that the CI status is all GREEN: https://dev.azure.com/u-boot/u-boot/_build/results?buildId=9225&view=res...
Changes in v8:
- Fix bootefi with tftp and wget. It would previously fail with an error message: "No UEFI binary known at 200000". Tested on Raspberry 3B+. Also fix the legacy wget. (Tom R.) - wget: add "Bytes transferred =" message and accept legacy syntax for better compatibility which also makes it easier to add a test to the test suite - wget: When no server name or address is supplied, use ${httpserverip} then ${serverip}. - wget: start the timer used for measuring throughput when the first data block is received. In other words: do not include DNS resolution and TCP connection time in measurement. It gives better numbers ;) but more importantly is how the legacy code works. - wget: handle non-200 result codes from the server as errors. - tftp: when no server name or ip is supplied, use ${tftpserverip} then fall back to ${serverip}. - New commit: "test/py: add HTTP (wget) test" - New commit: "net: wget: removed unused function wget_success()" - Change back all !CONFIG_IS_ENABLED(NO_NET) tests to (CONFIG_IS_ENABLED(NET) || CONFIG_IS_ENABLED(NET_LWIP)) since the NO_NET case is wrong when CONFIG_SPL_BUILD or CONFIG_TPL_BUILD is defined (Tom R.)
Changes in v7:
- Rebased onto master - Updated binary size comparisons in this cover letter. Note that the increase for imx8mp_evk_defconfig was wrong due to a configuration error.
Changes in v6:
- Rebased on next - "flash: prefix error codes with FL_" Update drivers/mtd/altera_qspi.c too (Tom R.) - "net: introduce alternative implementation as net-lwip/" Introduce a "Networking" top-level menu in the main Kconfig. Avoids having a lot of network-related symbols on the first screen of menuconfig. The "Networking stack" choice as well as the applicable symbols (depending on the selected choice) are now all inside this "Networking" menu. (Michal S.) For PROT_DHCP_LWIP and PROT_DNS_LWIP, use "select" PROT_UDP_LWIP rather than "depends on". Move NET_RANDOM_ETHADDR to the common ('if NET || NET_LWIP') block. Move SYS_RX_ETH_BUFFER out of 'if NET || NET_LWIP' since it is used unguarded in some code (e.g., am62x_beagleplay_r5) (Tom R.). - "net: split include/net.h into net{,-common,-legacy,-lwip}.h" Move net_random_ethaddr() to net-common.h. - "net: eth-uclass: add function eth_start_udev()" Fix typo and apply Tom R.'s R-b. - "net-lwip: add DHCP support and dhcp commmand" Convert !CONFIG_IS_ENABLED(NET) to CONFIG_IS_ENABLED(NO_NET) in board/xilinx/common/board.c to fix an issue with device having no MAC address (thanks Michal S.). Do the same at other places (icore_mx8mp.c, imx8mp_debix_model_a.c, board/ti/am335x/board.c, tiny-printf.c). Move CMD_MII and CMD_MDIO into 'if NET || NET_LWIP'. - "net-lwip: add TFTP support and tftpboot command": Fix help string. - "net: split cmd/net.c into cmd/net.c and cmd/net-common.c": Apply Ilias' R-b. - "net-lwip: add TFTP_BLOCKSIZE" Apply Ilias' R-b. I moved the TFTP_BLOCKSIZE Kconfig into this commit where it belongs (it was previously in "net" split ... net.h").
Changes in v5:
- Rebased on next - Refactor Kconfig options to avoid duplicates - Library functions use a more consistent naming (dhcp_loop(), ping_loop() etc.) and take a struct udevice * parameter (Heinrich S.) - Do not use net_process_receive_packet() for input anymore. Instead of calling eth_rx() which would invoke net_process_receive_packet(), we call a new net_lwip_rx(udev) function which invokes the device recv() and pushes the packets up the lwIP stack. Thus everything is tied to a udevice now. (Heinrich S.) - Add "configs: replace '# CONFIG_NET is not set' with CONFIG_NO_NET=y" (Tom R.) - tftp: unify display with legacy command: add throughput, 65 hashes per line, one every 10 blocks received (Tom R.) - Moved net-lwip/* to net/lwip/* (Simon G.) - Rename static function low_level_output() to linkoutput() since it is the name used in the lwIP netif struct. - Fixed off-by-one in parse_url() which could cause wget to fail when passed a URL with a host name (as opposed to a URL with an IP address). - Improved TFTP performance by adding support for the blksize option (patches "lwip: tftp: add support of blksize option to client" and "net-lwip: add TFTP_BLOCKSIZE) (Tom R.) - Add an optional port number to the tftp command for easier testing (syntax: tftp [[ip:[port:]]filename]) - wget: display an "unsupported URI" error if uri is not http:// (Jon H.) - Adjusted the lwIP TCP options in lib/lwip/u-boot/lwipopts.h for better performance, in particular TCP_WND. - Add "net: fec_mxc_init(): do not ignore return status of fec_open()" - Set the proper environment variables when DHCP succeeds (ipaddr%d etc.) and read the proper ones for the given device in new_netif(), allowing correct behavior when several adapters are available (tested on i.MX8M Plus). - Fix an alignment issue with outgoing packets (see the linkoutput() function). With that the i.MX8M Plus ENET1 interface works properly. (reported by Tim H.). - Add review tags
Changes in v4:
- Fixed the DHCP algorithm which was missing a sys_timeout() call in the "fine timer" callback. This should close the issue that Tom R. reported with his Raspberry Pi 3 (it does fix it on mine). - The DHCP exchange timeout is increased from 2 to 10 seconds - The DHCP exchange can be interrupted with Ctrl-C. - "net: introduce alternative implementation as net-lwip/": rework dependencies. A few symbols have 'depends on !NET_LWIP' and in addition 'NET_LWIP depends on !SANDBOX'. Sandbox, DSA and fastboot are unsupported, because they are deeply welded to the current stack. - All network commands (dns, ping, tftp and wget): * Get rid of global variables (Ilias A.) * Use printf() rather than log_info() - "net-lwip: add ping command": use packet count instead of timeout, fix code style (Ilias A.) - Add "net: split cmd/net.c into cmd/net.c and cmd/net-common.c" extracted from the wget patch (Ilias A.). - Add "net: split include/net.h into net{,-common,-legacy,-lwip}.h" (Ilias A.) - Add "flash: prefix error codes with FL_" which is required to avoid name clashes when splitting net.h - Reworked the initialization of the lwIP stack. One and only one network interface (struct netif) is added for the duration of the command that uses that interface. That's commit "net-lwip: add DHCP support and dhcp commmand". - Drop "test: dm: dsa, eth: disable tests when CONFIG_NET_LWIP=y", not needed now that NET_LWIP depend on !SANDBOX. - qemu_arm64_lwip_defconfig now enables CMD_DNS and CMD_WGET (so that all the supported network commands are available).
Changes in v3:
- Make NET_LWIP a Kconfig choice in patch "net: introduce alternative implementation as net-lwip/" (Tom R.) - Drop the patch introducing lwIP as a Git subtree and document the git command in the cover letter instead (Tom R.) - "net-lwip: add TFTP support and tftpboot command": use the same "Bytes transferred =" message as in the legacy implementation (Tom R., Maxim U.) - Drop "test/py: net: add _lwip variants of dhcp, ping and tftpboot tests" which is not needed anymore. - Add missing kfree() calls in cmd/net-common.c and fix the parsing of decimal address in net-lwip/wget.c (patch "net-lwip: add wget command") (Maxim U.) - "net-lwip: add ping command": drop the ICMP payload (Ilias A.). Set the sequence number to zero when entering ping_loop().
Changes in v2:
** Address comments from Ilias A.
- "net-lwip: add wget command" Implement the wget_with_dns() function to do most of the wget work and call it from do_wget(). This allows to simplify patch "net-lwip: add support for EFI_HTTP_BOOT".
- "net-lwip: import net command from cmd/net.c" Move a few functions from cmd/net.c to a new file cmd/net-common.c rather than duplicating then in cmd/net-lwip.c.
- "net-lwip: add support for EFI_HTTP_BOOT" Since wget_with_dns() is now implemented in "net-lwip: add wget command", just enable the wget command when the lwIP stack is enabled and EFI_HTTP_BOOT is requested.
** Address comments from Tom R.
- "net-lwip: add DHCP support and dhcp commmand", "net-lwip: add TFTP support and tftpboot command", "net-lwip: add ping command", "net-lwip: add dns command", "net-lwip: add wget command" Do not introduce new CMD_XXX_LWIP symbols and use existing CMD_XXX instead.
- "configs: add qemu_arm64_lwip_defconfig" Use #include <configs/qemu_arm64_defconfig>.
- "net-lwip: import lwIP library under lib/lwip" Patch removed and replaced by the introduction of a Git subtree: "Squashed 'lib/lwip/lwip/' content from commit 0a0452b2c3".
Note that I have not yet addressed your comments on "test: dm: dsa, eth: disable tests when CONFIG_NET_LWIP=y"). I need some more time for that and I think running CI on this v2 will help better understand what is needed for v3.
** Miscellaneous improvements
- "net: introduce alternative implementation as net-lwip/":
* Make DFU_OVER_TFTP not DFU_TFTP incompatible with NET_LWIP. It seems quite natural to supplement "depends on NET" with "&& !NET_LWIP". * Make PROT_*_LWIP not visible by removing the Kconfig prompt.

The tools-only defconfig causes troubles on MacOSX due to the default C compiler being Clang (LLVM) rather than GCC and more specifically due to [1]. Therefore replace "# CONFIG_FOO is not set" with the equivalent "CONFIG_FOO=n" using the following command:
$ sed -i -e 's/# (CONFIG_[^ ]*) is not set/\1=n/' \ configs/tools-only_defconfig
This fixes the tools_only_macOS CI job on GitHub [2].

Introduce ETH_SANDBOX_LWIP which enables a mock driver similar to ETH_SANDOX but without the dependencies on the legacy network stack (NET) so that it may be enabled when the lwIP stack (NET_LWIP) is introduced. The driver does nothing at this stage but its presence will allow dm_test_iommu_noiommu [1] to pass.

When DSA_SANDBOX is not set, the sandbox tests fail as follows:
$ ./test/py/test.py --build-dir=$(pwd) -k bootdev_test_any [...] Test: bootdev_test_any: bootdev.c test/boot/bootdev.c:156, bootdev_test_any(): "mmc2" = media->name: Expected "mmc2", got "mmc0" [...]
This is due to the device list containing two less entries than expected. Therefore, adjust the expected index to be two less when DSA_SANDBOX is disabled.
The actual use case is NET_LWIP=y (to be introduced in later patches) which implies DSA_SANDBOX=n for the time being.

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.

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.

Build the lwIP library when NET_LWIP is enabled. The following files are adaptation layers written specially for U-Boot:
lib/lwip/u-boot/arch/cc.h lib/lwip/u-boot/arch/sys_arch.h (empty) lib/lwip/u-boot/limits.h (empty) lib/lwip/u-boot/lwipopts.h
They were initially contributed by Maxim in a previous RFC patch series.
The lwIP stack needs to be added as a Git subtree with the following command:
$ git subtree add --squash --prefix lib/lwip/lwip \ https://github.com/lwip-tcpip/lwip.git STABLE-2_2_0_RELEASE

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.

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.

Acked-by: Ilias Apalodimas ilias.apalodimas@linaro.org
The TFTP app should not bind to the TFTP server port when configured as a client. Instead, the local port should be chosen from the dynamic range (49152 ~ 65535) so that if the application is stopped and started again, the remote server will not consider the new packets as part of the same context (which would cause an error since a new RRQ would be unexpected).

Implement do_tftpb(). This implementation of the tftp command supports an optional port number. For example:
tftp 192.168.0.30:9069:file.bin
It also supports taking the server IP from ${tftpserverip} if defined, before falling back to ${serverip}.

Add support for the wget command with NET_LWIP. The command normally expects a URL: wget [loadaddr] url, but it also accepts the legacy syntax: wget [loadaddr] [server:]file. The server IP may alternatively be supplied via ${httpserverip} which has higher priority than ${serverip}.

Add support for the wget command with NET_LWIP. The command normally expects a URL: wget [loadaddr] url, but it also accepts the legacy syntax: wget [loadaddr] [server:]file. The server IP may alternatively be supplied via ${httpserverip} which has higher priority than ${serverip}.
Based on code initially developed by Maxim U.

The TFTP protocol uses a default block size of 512 bytes. This value is sub-optimal for ethernet devices, which have a MTU (Maximum Transmission Unit) of 1500 bytes. When taking into acount the overhead of the IP and UDP layers, this leaves 1468 bytes for the TFTP payload.
This patch introduces a new function: tftp_client_set_blksize() which may be used to change the block size from the default. It has to be called after tftp_client_init() and before tftp_get(). If the server does not support the option, the client will still accept to receive 512-byte blocks.

Add support for setting the TFTP block size. The default value (1468) is fine for Ethernet and allows a better throughput than the TFTP default (512), if the server supports the blksize option of course.
I tested this change with qemu_arm64_lwip_defconfig. The throughput is now 875 KiB/s vs. 313 KiB/s before. That is still a low number, but I think we can't expect more without implementing the windowsize option.
