net: lwip: enable debug traces for SNTP when CONFIG_LWIP_DEBUG is set

2025-09-30T10:01:36Z

Now that SNTP is supported, enable SNTP debug traces when LWIP_DEBUG is enabled. In particular, this allows to see which NTP servers are received during DHCP. Signed-off-by: Jerome Forissier

lwip: tftp: resend initial request

2025-08-18T13:47:58Z

The TFTP implementation does not resend the initial request if there is no response from the server. Since TFTP is based on UDP, there should be a mechanism to deal with unreliable transmissions at this point, similar to what we have for data packets. Therefore, introduce request retransmission.

net: lwip: add Kconfig option to show ICMP unreachable errors

2025-08-18T12:08:57Z

Add Kconfig symbol LWIP_ICMP_SHOW_UNREACH which, when enabled, prints a message to the console upon reception of ICMP unreachable messages. For example: $ make qemu_arm64_lwip_defconfig $ qemu-system-aarch64 -M virt -cpu max -nographic -bios u-boot.bin [...] => dhcp DHCP client bound to address 10.0.2.15 (0 ms) => tftp 192.168.0.100:69:Image Using virtio-net#32 device TFTP from server 192.168.0.100; our IP address is 10.0.2.15 Filename 'Image'. Load address: 0x40200000 Loading: ICMP destination unreachable (host unreachable) from 192.168.0.16 Timeout! => tftp 192.168.0.16:69:Image Using virtio-net#32 device TFTP from server 192.168.0.16; our IP address is 10.0.2.15 Filename 'Image'.

lwip: provide a sntp_format_time() function

2025-08-01T07:30:47Z

Provide a trivial implementation of sntp_format_time() to fix a build error when CONFIG_LWIP_DEBUG=y: lib/lwip/lwip/src/apps/sntp/sntp.c: In function ‘sntp_format_time’: lib/lwip/lwip/src/apps/sntp/sntp.c:283:10: error: implicit declaration of function ‘ctime’ [-Werror=implicit-function-declaration] 283 | return ctime(&ut); | ^~~~~ Signed-off-by: Jerome Forissier

net: lwip: enable IP_FRAG and IP_REASSEMBLY

net, net-lwip: wget: suppress console output when called by EFI

2025-05-20T13:43:08Z

Functions called from EFI applications should not do console output. Refactor the wget code to implement this requirement. The wget_http_info struct is used to hold the boolean that signifies whether the output is allowed or not. Signed-off-by: Jerome Forissier Reported-by: Heinrich Schuchardt

Kbuild: Always use $(PHASE_)

2025-04-11T18:16:44Z

It is confusing to have both "$(PHASE_)" and "$(XPL_)" be used in our Makefiles as part of the macros to determine when to do something in our Makefiles based on what phase of the build we are in. For consistency, bring this down to a single macro and use "$(PHASE_)" only. Signed-off-by: Tom Rini

lwip: tls: warn when no CA exists amd log certificate validation errors

2025-03-11T13:16:03Z

Using HTTPS without root (CA) certificates is a security issue. Print a warning in this case. Also, when certificate verification fail, print an additional message because "HTTP client error 4" is not very informative (4 is HTTPC_RESULT_ERR_CLOSED).
