rocker: fix memory leak in rocker_world_port_post_fini()

2026-02-06T15:57:31Z

[ Upstream commit 8d7ba71e46216b8657a82ca2ec118bc93812a4d0 ] In rocker_world_port_pre_init(), rocker_port->wpriv is allocated with kzalloc(wops->port_priv_size, GFP_KERNEL). However, in rocker_world_port_post_fini(), the memory is only freed when wops->port_post_fini callback is set: if (!wops->port_post_fini) return; wops->port_post_fini(rocker_port); kfree(rocker_port->wpriv); Since rocker_ofdpa_ops does not implement port_post_fini callback (it is NULL), the wpriv memory allocated for each port is never freed when ports are removed. This leads to a memory leak of sizeof(struct ofdpa_port) bytes per port on every device removal. Fix this by always calling kfree(rocker_port->wpriv) regardless of whether the port_post_fini callback exists.

Since '1 << rocker_port->pport' may be undefined for port >= 32, cast the left operand to 'unsigned long long' like it's done in 'rocker_port_set_enable()' above. Compile tested only.

net: annotate writes on dev->mtu from ndo_change_mtu()

2024-05-07T23:19:14Z

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 Reported-by: Simon Horman Closes: https://lore.kernel.org/netdev/20240505144608.GB67882@kernel.org/ Reviewed-by: Jacob Keller Reviewed-by: Sabrina Dubroca Reviewed-by: Simon Horman Acked-by: Shannon Nelson Link: https://lore.kernel.org/r/20240506102812.3025432-1-edumazet@google.com Signed-off-by: Jakub Kicinski
