cmd: lwip/wget: avoid NULL dereference in _set_cacert()

2025-12-18T15:27:15Z

Running `wget cacert builtin` leads to a crash in _set_cacert(): Unhandled exception: Load access fault Function _set_cacert() dereferences variable wget_info. We must initialize it before executing the cacert sub-command.

net: lwip: ping: set net_try_count to 1

2025-08-18T13:47:58Z

The legacy network stack sets net_try_count to 1 at the beginning of the net_loop() function. This is required for net_start_again() to work properly. Therefore, set the variable accordingly in the do_ping() function when NET_LWIP=y. This fixes an issue where a ping to an unreachable destination would run twice on the same network device. For example with qemu_arm64_lwip_defconfig: => dhcp DHCP client bound to address 10.0.2.15 (3 ms) => ping 10.0.0.1 Using virtio-net#32 device ping failed; host 10.0.0.1 is not alive Using virtio-net#32 device ping failed; host 10.0.0.1 is not alive => QEMU: Terminated Signed-off-by: Jerome Forissier

lwip: sntp: remove redundant sys_check_timeouts()

2025-08-18T13:47:58Z

Now that sys_check_timeouts() is called in net_lwip_rx(), there is no need to call it from the SNTP receive loop. Remove the redundant call. Signed-off-by: Jerome Forissier

lwip: dns: do not print IP address when a variable is specified

2025-07-08T09:07:37Z

When calling "dns ", do not print out the IP address of onto the console. Print it only when no variable is passed. The reason is to be able to call do_dns() from another command in need of the DNS services without polluting the output. Signed-off-by: Jerome Forissier

lwip: dns: do not return CMD_RET_FAILURE on successful resolution

2025-07-08T09:07:37Z

The DNS loop checks for a non-zero IP address after DNS resolution, but the address is in fact never copied into the context. Fix that. Signed-off-by: Jerome Forissier
