Re: [PATCH net] net/rds: fix tcp stream corruption with large pages

Hello:

This patch was applied to netdev/net.git (main)
by Jakub Kicinski [off-list ref]:

rds_message_map_pages() assigns PAGE_SIZE bytes to every
scatterlist entry, even when total_len ends in a partial page. The RDS
congestion map is defined as 8192 bytes, so on systems with PAGE_SIZE
greater than 8192 the scatterlist maps bytes beyond the end of the
congestion map.  RDS-TCP transmits the SG contents according to those
lengths, so the extra bytes become part of the TCP RDS stream and are
interpreted as subsequent RDS message headers, corrupting the stream.
