wireguard: selftests: load nf_conntrack if not present

2024-12-09T09:32:12+00:00

[ Upstream commit 0290abc9860917f1ee8b58309c2bbd740a39ee8e ] Some distros may not load nf_conntrack by default, which will cause subsequent nf_conntrack sets to fail. Load this module if it is not already loaded.

wireguard: selftests: use acpi=off instead of -no-acpi for recent QEMU

2024-07-18T11:21:23+00:00

commit 2cb489eb8dfc291060516df313ff31f4f9f3d794 upstream. QEMU 9.0 removed -no-acpi, in favor of machine properties, so update the Makefile to use the correct QEMU invocation.

wireguard: selftests: set RISCV_ISA_FALLBACK on riscv{32,64}

2024-04-03T13:28:37+00:00

[ Upstream commit e995f5dd9a9cef818af32ec60fc38d68614afd12 ] This option is needed to continue booting with QEMU. Recent changes that made this optional meant that it gets unset in the test harness, and so WireGuard CI has been broken. Fix this by simply setting this option.

treewide: drop CONFIG_EMBEDDED

2023-08-21T20:46:25+00:00

There is only one Kconfig user of CONFIG_EMBEDDED and it can be switched to EXPERT or "if !ARCH_MULTIPLATFORM" (suggested by Arnd).

wireguard: netlink: send staged packets when setting initial private key

2023-07-03T08:17:52+00:00

Packets bound for peers can queue up prior to the device private key being set. For example, if persistent keepalive is set, a packet is queued up to be sent as soon as the device comes up. However, if the private key hasn't been set yet, the handshake message never sends, and no timer is armed to retry, since that would be pointless. But, if a user later sets a private key, the expectation is that those queued packets, such as a persistent keepalive, are actually sent. So adjust the configuration logic to account for this edge case, and add a test case to make sure this works. Maxim noticed this with a wg-quick(8) config to the tune of: [Interface] PostUp = wg set %i private-key somefile [Peer] PublicKey = ... Endpoint = ... PersistentKeepalive = 25 Here, the private key gets set after the device comes up using a PostUp script, triggering the bug.

random: use random.trust_{bootloader,cpu} command line option only

2022-11-18T01:18:10+00:00

It's very unusual to have both a command line option and a compile time option, and apparently that's confusing to people. Also, basically everybody enables the compile time option now, which means people who want to disable this wind up having to use the command line option to ensure that anyway. So just reduce the number of moving pieces and nix the compile time option in favor of the more versatile command line option. Signed-off-by: Jason A. Donenfeld

wireguard: selftests: do not install headers on UML

2022-09-20T18:26:14+00:00

Since 1b620d539ccc ("kbuild: disable header exports for UML in a straightforward way"), installing headers fails on UML, so just disable installing them, since they're not needed anyway on the architecture.

wireguard: selftests: set CONFIG_NONPORTABLE on riscv32

2022-08-12T14:47:12+00:00

When the CONFIG_PORTABLE/CONFIG_NONPORTABLE switches were added, various configs were updated, but the wireguard config was forgotten about. This leads to unbootable test kernels, causing CI fails. Add CONFIG_NONPORTABLE=y to the wireguard test suite configuration for riscv32. Fixes: 44c1e84a38a0 ("RISC-V: Add CONFIG_{NON,}PORTABLE") Signed-off-by: Jason A.
