Title
net: mana: Fix RX buf alloc_size alignment and atomic op panic
Summary
In the Linux kernel, the following vulnerability has been resolved:
net: mana: Fix RX buf alloc_size alignment and atomic op panic
The MANA driver's RX buffer alloc_size is passed into napi_build_skb() to
create SKB. skb_shinfo(skb) is located at the end of skb, and its alignment
is affected by the alloc_size passed into napi_build_skb(). The size needs
to be aligned properly for better performance and atomic operations.
Otherwise, on ARM64 CPU, for certain MTU settings like 4000, atomic
operations may panic on the skb_shinfo(skb)->dataref due to alignment fault.
To fix this bug, add proper alignment to the alloc_size calculation.
Sample panic info:
[ 253.298819] Unable to handle kernel paging request at virtual address ffff000129ba5cce
[ 253.300900] Mem abort info:

[ 253.305172] EA = 0, S1PTW = 0
