The following commit has been merged in the master branch: commit 1eb2cded45b35816085c1f962933c187d970f9dc Author: Eric Dumazet <edumazet(a)google.com> Date: Mon May 6 10:28:12 2024 +0000 net: annotate writes on dev->mtu from ndo_change_mtu() Simon reported that ndo_change_mtu() methods were never updated to use WRITE_ONCE(dev->mtu, new_mtu) as hinted in commit 501a90c94510 ("inet: protect against too small mtu values.") We read dev->mtu without holding RTNL in many places, with READ_ONCE() annotations. It is time to take care of ndo_change_mtu() methods to use corresponding WRITE_ONCE() Signed-off-by: Eric Dumazet <edumazet(a)google.com> Reported-by: Simon Horman <horms(a)kernel.org> Closes: https://lore.kernel.org/netdev/20240505144608.GB67882@kernel.org/ Reviewed-by: Jacob Keller <jacob.e.keller(a)intel.com> Reviewed-by: Sabrina Dubroca <sd(a)queasysnail.net> Reviewed-by: Simon Horman <horms(a)kernel.org> Acked-by: Shannon Nelson <shannon.nelson(a)amd.com> Link: https://lore.kernel.org/r/20240506102812.3025432-1-edumazet@google.com Signed-off-by: Jakub Kicinski <kuba(a)kernel.org> diff --git a/drivers/infiniband/ulp/ipoib/ipoib_main.c b/drivers/infiniband/ulp/ipoib/ipoib_main.c index 6f2a688fccbfb..32f6a28b02b1e 100644 --- a/drivers/infiniband/ulp/ipoib/ipoib_main.c +++ b/drivers/infiniband/ulp/ipoib/ipoib_main.c @@ -238,7 +238,7 @@ static int ipoib_change_mtu(struct net_device *dev, int new_mtu) ipoib_warn(priv, "mtu > %d will cause multicast packet drops.\n", priv->mcast_mtu);
