Subject: [PATCH net 0/6] wireguard fixes for 6.9-rc1

Hey netdev,

This series has four WireGuard fixes:

1) Annotate a data race that KCSAN found by using READ_ONCE/WRITE_ONCE,
   which has been causing syzkaller noise.

2) Use the generic netdev tstats allocation and stats getters instead of
   doing this within the driver.

3) Explicitly check a flag variable instead of an empty list in the
   netlink code, to prevent a UaF situation when paging through GET
   results during a remove-all SET operation.

4) Set a flag in the RISC-V CI config so the selftests continue to boot.

Please apply these!

Thanks,
Jason
