2025-02-28legacy-net: wget: fix wget_info handling after new tcp legacy stackAdriano Cordova
Check wget_info->buffer_size for overflow and do not clean the wget_info struct on failure, let the owner of the struct handle the error. The latter is necesary , e.g., for when a request fails because the provided buffer was too small. Signed-off-by: Adriano Cordova <adriano.cordova@canonical.com>
2024-12-28net/tcp: improve tcp framework, use better state machineMikhail Kshevetskiy
Changes: * Fix initial send sequence always zero issue * Use state machine close to RFC 9293. This should make TCP transfers more reliable (now we can upload a huge array of data from the board to external server) * Improve TCP framework a lot. This should make tcp client code much more simple. * rewrite wget with new tcp stack * rewrite fastboot_tcp with new tcp stack It's quite hard to fix the initial send sequence (ISS) issue with the separate patch. A naive attempt to fix an issue inside the tcp_set_tcp_header() function will break tcp packet retransmit logic in wget and other clients. Example: Wget stores tcp_seq_num value before tcp_set_tcp_header() will be called and (on failure) retransmit the packet with the stored tcp_seq_num value. Thus: * the same ISS must allways be used (current case) * or tcp clients needs to generate a proper ISS when required. A proper ISS fix will require a big redesing comparable with a this one.

2024-12-04efi_loader: net: set EFI bootdevice device path to HTTP when loaded from wgetAdriano Cordova
Set the device path of the efi boot device to an HTTP device path (as formed by efi_dp_from_http) when the next boot stage is loaded using wget (i.e., when wget is used with wget_info.set_bootdev=1). When loaded from HTTP, the device path should account for it so that the next boot stage is aware (e.g. grub only loads its http stack if it itself was loaded from http, and it checks this from its device path).

Commit 2dd076a9c1b4 ("net: wget: integrate struct wget_info into legacy wget code") introduced function wget_fill_info() which retrieves the headers from the HTTP server response. As we want to parse the string in later patches we need to ensure that it is NUL terminated. We must further check that wget_info->headers in not NULL. Otherwise a crash occurs.

2024-11-16net: wget: make wget_with_dns return value compatible with its lwip versionAdriano Cordova
There are two wget_with_dns functions, one in the legacy network stack and one in lwip, but the return values are not compatible. This commit modifies the legacy version of wget_with_dns so that the return values are compatible: 0 on success, otherwise a negative error.

2024-09-20wget: rework the logic to validate the load addressSughosh Ganu
Use the lmb_read_check() function to verify if it is safe to use a region of memory to load data from the wget command. The current logic checks the amount of free memory available, starting from the 'load address'. This call fails if the same region of memory has been used earlier. This used to work earlier as the LMB memory map had a local scope and was not persistent. Fix this issue by using the lmb_read_check() call instead which only returns an error in case the memory region has been marked for not allowing re-use.

The current LMB API's for allocating and reserving memory use a per-caller based memory view. Memory allocated by a caller can then be overwritten by another caller. Make these allocations and reservations persistent using the alloced list data structure. Two alloced lists are declared -- one for the available(free) memory, and one for the used memory. Once full, the list can then be extended at runtime.

2024-04-16net: wget: Support retransmission a dropped packetYasuharu Shibata
The server sends multiple packets without waiting for an ACK by window control and if some packets are dropped, wget will return an ACK including the dropped packets. Following log indicates this issue. wget_handler() wget: Transferring, seq=97bbdd4a, ack=30,len=580 wget_handler() wget: Transferring, seq=97bbedca, ack=30,len=580 First packet of TCP sequence number is 0x97bbdd4a. Second packet of TCP sequence number should be 0x97bbe2ca, however it is 0x97bbedca and returns its ACK, so the server suppose that 0x97bbe2ca and 0x97bbedca are received appropriately. In this case, 0x97bbe2ca was lost and the data of wget was broken. In this patch, next_data_seq_num holds the next expected TCP sequence number. If the TCP sequence number different from next_data_seq_num, trying to retransmit the packet.

2023-12-19net: wget: Support non-default HTTP portMarek Vasut
Currently the wget command is hard wired to HTTP port 80. This is inconvenient, as it is extremely easy to start trivial HTTP server as an unprivileged user using e.g. python http module to serve the files, but such a server has to run on one of the higher ports: " $ python3 -m http.server -d $(pwd) 8080 " Make it possible to configure HTTP server port the same way it is possible to configure TFTP server port, using environment variable 'httpdstp' (similar to 'tftpdstp'). Retain port 80 as the default fallback port. This way, users can start their own trivial server and conveniently download whatever files they need into U-Boot.
