Subject: [PATCH] gro: check payload length after trim
|

|

When packet is padded with extra bytes the

the validation of the payload length should be done
|

after the trim operation

a 3rd packet which is matching the sequence of the 2nd packet the

prev_idx will be 1 and not 2, hence resulting in packet re-ordering

Subject: [PATCH] gro: trim tail padding bytes
|
||||
|
||||
Exclude CRC fields, the minimum Ethernet packet
|
||||
length is 60 bytes. When the actual packet length
|
||||
is less than 60 bytes, padding is added to the tail.
|
||||
When GRO is performed on a packet containing a padding
|
||||
field, mbuf->pkt_len is the one that contains the
|
||||
padding field, which leads to the error of thinking
|
||||
of the padding field as the actual content of the packet.
|
||||
We need to trim away this extra padding field during
|
||||
GRO processing.
