net: lwip: allow DM_DSA=y when NET_LWIP=y

2025-04-23T08:02:49Z

Now that the DSA tests in test/dm/dsa.c are compatible with NET_LWIP, remove the dependency of DM_DSA on NET. Signed-off-by: Jerome Forissier Reviewed-by: Simon Glass

net: lwip: use timer_early_get_count() when CONFIG_SANDBOX_TIMER=y

2025-04-23T08:02:49Z

When the sandbox timer is available, use it. This allows skipping time in the tests (sandbox_eth_skip_timeout()). Signed-off-by: Jerome Forissier Reviewed-by: Simon Glass

net: lwip: add restart support to ping

2025-04-23T08:02:49Z

Use net_start_again() in do_ping() to determine if a failed ping should be restarted on a different interface. Signed-off-by: Jerome Forissier Reviewed-by: Simon Glass

net: lwip: provide net_start_again()

2025-04-23T08:02:49Z

Implement net_start_again() when NET_LWIP=y in a very similar way to NET. This will be used in a future commit to determine if a failed ping needs to be tried again on a different interface. Signed-off-by: Jerome Forissier Reviewed-by: Simon Glass

net: lwip: fix initialization sequence before a command

2025-04-23T08:02:49Z

The things that are done prior to executing a network command with NET_LWIP are not consistent with what is done with NET. It impacts the selection of the current device, and more precisely if the active device is invalid NET would return an error while NET_LWIP would try to pick a new device. This incorrect behavior was detected thanks to the eth_rotate sandbox test (dm_test_eth_rotate()). Fix it by re-using a sequence similar to what NET has in net_loop(). This piece of code is inserted in a function called net_lwip_eth_start() renamed from net_lwip_eth_set_current(). Signed-off-by: Jerome Forissier Reviewed-by: Simon Glass

net: dhcpv6: remove excluded middle expression

net: dhcp6: Send DHCPv6 using multicast MAC

2025-04-23T07:58:07Z

In IPv6, the broadcast MAC address is not used. Instead, it should use the multicast address (see RFC RFC2464). Add IPV6_ALL_NODE_ETH_ADDR macro for clarity. Signed-off-by: Sean Edmond Reviewed-by: Jerome Forissier

Merge patch series "Switch to using $(PHASE_) in Makefiles"

2025-04-11T18:16:49Z

Tom Rini says: This series switches to always using $(PHASE_) in Makefiles when building rather than $(PHASE_) or $(XPL_). It also starts on documenting this part of the build, but as a follow-up we need to rename doc/develop/spl.rst and expand on explaining things a bit.

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

Merge patch series "Annotate switch/case fallthrough cases"

2025-04-08T22:24:12Z

Andre Przywara says: C's implicit fallthrough behaviour in switch/case statements can lead to subtle bugs. Quite some while ago many compilers introduced warnings in those cases, requiring intentional fallthrough's to be annotated. So far we were not enabling that compiler option, so many ambiguities and some bugs in the code went unnoticed. This series adds the required annotations in code paths that the first stage of the U-Boot CI covers. There is a large number of cases left in the libbz2 code. The usage of switch/case is borderline insane there, labels are hidden in macros, and there are no breaks, but just goto's. Upstream still uses very similar code, without any annotations. I still am not 100% sure those are meant to fall through or not, and plan to do further investigations, but didn't want to hold the rest of the patches back. You can see for yourself by applying patch 18/18 and building for sandbox64, for instance. Because of this we cannot quite enable the warning in the Makefile yet, but those fixes are worth regardless, and be it to increase readability. Please note that those patches do not fix anything, really, they just add those fallthrough annotations, so the series is not really critical.
