> Subject: [PATCH] examples/ipsec-secgw: fix partial overflow
>=20
> Case of partial overflow detected with ASan. Added extra padding to cdev_=
key
> structure.
>=20
> This structure is used for the key in hash table.
> Padding is added to force the struct to use 8 bytes, to ensure memory is
> notread past this structs boundary (the hash key calculation reads 8 byte=
s if
> this struct is size 5 bytes).
> The padding should be zeroed.
> If fields are modified in this struct, the padding must be updated to ens=
ure
> multiple of 8 bytes size overall.
