From 90c05f68fcab57d669233033d34e52b8d55d57dd Mon Sep 17 00:00:00 2001 From: Jerome Forissier Date: Mon, 4 Aug 2025 14:51:01 +0200 Subject: net: lwip: ping: set net_try_count to 1 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 --- include/net-lwip.h | 2 ++ 1 file changed, 2 insertions(+) (limited to 'include/net-lwip.h') diff --git a/include/net-lwip.h b/include/net-lwip.h index f54f23471f1..e88e2186635 100644 --- a/include/net-lwip.h +++ b/include/net-lwip.h @@ -18,6 +18,8 @@ extern size_t cacert_size; extern enum auth_mode cacert_auth_mode; extern bool cacert_initialized; +extern int net_try_count; + int set_cacert_builtin(void); enum proto_t { -- cgit v1.2.3
