[PATCH v13 00/21] Introduce the lwIP network stack
by Jerome Forissier 07 Nov '24

07 Nov '24

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 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.

With that the CI status is all GREEN: https://dev.azure.com/u-boot/u-boot/_build/results?buildId=9225&view=results 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.

wget bug report
by Simon Glass 06 Nov '24

06 Nov '24

Hi Jerome, Just something I noticed earlier...when running 'ut lib' I see this failure on sandbox: test/cmd/wget.c:215, net_test_wget(): 0 == run_command("wget ${loadaddr} 1.1.2.2:/index.html", 0): Expected 0x0 (0), got 0x1 (1) Also, since it is testing a command and is in test/cmd it really should be in the 'cmd' test suite, not 'lib'. Regards, Simon

[PATCH v12 00/13] net: tcp: improve tcp support in legacy stack
by Mikhail Kshevetskiy 06 Nov '24

06 Nov '24

Legacy TCP stack is bad. Here are some of the known issues: * tcp packet from other connection can break a current one * tcp send sequence always starts from zero * bad tcp options processing * strange assumptions on packet size for selective acknowledge * tcp interface assumes one of the two scenarios: - data downloading from remote host to a board - request-response exchange with a small packets so it's not possible to upload large amount of data from the board to remote host. * wget test generate bad tcp stream, test should fail but it passes instead This series of patches fixes all of the above issues. The benefits: * A lot of bug was fixed * Better and more reliable TCP state machine * Tcp clients becomes smaller/simpler * Data uploading was fixed (now it's possible to transmit a huge amount of data from the board to remote host) * Netcat over tcp was implemented. Netcat supports data downloading/uploading from/to remote host in client/server mode. * An example web-server implementation. This code can be used as a base for web-based firmware uploading used by some vendors. Modification was verified with * firmware downloading via u-boot wget command * fastboot over tcp * netcat linux client * Firefox/Chrome/Edge using example web-server implementation Changes v2: * cover letter was added * some patches were removed Changes v3: * better cover letter Changes v4: * fix bug in debug output * add more comments * code style fixes Changes v5: * old patches were occasionally sent with v4 * add back web-server patches * fix bug in debug output * add more comments * code style fixes Changes v6: * fix the wget test * improve description of "simplify tcp header filling code" patch Changes v7: * fix include ordering * improve option descriptions * fix a lot of extra brackets and comparisons against NULL / 0 * add empty lines before final returns * fixed a bug with zero size httpd uploads Changes v8: * [tcp] add function to restart rx inactivity timeout. This may help in the cases where remote peer waits for u-boot data, but u-boot is busy with long executing action * [httpd] add function returning underlying tcp stream from request id. This (with the above change) allows avoid connection break for the long processing post requests. Changes v9: * rebase all changes on top of origin/next * update test/cmd/wget patch description (bad tcp ack/seq issue was already fixed in origin/next) * tcp: add rx/tx packet counters to a tcp_stream structure * wget: use tcp rx packet counter instead of own one * netcat: use tcp rx/tx packet counters instead of own one Changes v10: * netcat: fix bug appeared after rx/tx packet counter addition * rebased on top of v2024.10 Changes v11: * fix spelling in cover letter Changes v12: * rebase on top of master branch (3df6145db0e) * slightly change tcp->rx() & tcp->tx() callback declarations, this allow us to terminate a connection if something goes wrong in rx/tx paths. * set net_boot_file_size variable in httpd_upload * set filesize env variable to a proper value netcat and httpd_upload Mikhail Kshevetskiy (13): net/tcp: fix TCP options processing net/tcp: fix selective acknowledge net/tcp: put connection specific data into a tcp_stream structure net/tcp: add connection info to tcp_stream structure net/tcp: rename ack_edge and seq_init to more common rcv_nxt and irs net/tcp: improve tcp framework, use better state machine test/cmd/wget: fix the test net/tcp: simplify tcp header filling code net/tcp: define a fallback value for rcv_wnd size net/net: fix include ordering net/netcat: add netcat over tcp support net/httpd: add httpd common code net/httpd-upload: an example web-server implementation for file uploading arch/sandbox/include/asm/eth.h | 4 + cmd/Kconfig | 35 + cmd/net.c | 55 +- include/net-legacy.h | 7 +- include/net/httpd-upload.h | 12 + include/net/httpd.h | 71 ++ include/net/netcat.h | 20 + include/net/tcp.h | 258 ++++++- include/net/wget.h | 8 - net/Kconfig | 14 + net/Makefile | 3 + net/fastboot_tcp.c | 193 ++--- net/httpd-upload.c | 173 +++++ net/httpd.c | 735 ++++++++++++++++++ net/net.c | 60 +- net/netcat.c | 194 +++++ net/tcp.c | 1297 ++++++++++++++++++++++---------- net/wget.c | 476 ++++-------- test/cmd/wget.c | 58 +- 19 files changed, 2766 insertions(+), 907 deletions(-) create mode 100644 include/net/httpd-upload.h create mode 100644 include/net/httpd.h create mode 100644 include/net/netcat.h create mode 100644 net/httpd-upload.c create mode 100644 net/httpd.c create mode 100644 net/netcat.c -- 2.45.2
