Re: [PATCH net-next v5] sctp: auth: discard auth_chunk when skb_clone fails

When processing AUTH + COOKIE-ECHO packets, if skb_clone() fails
due to memory pressure, chunk->auth_chunk is NULL. The original
code still sets chunk->auth = 1 and continues, leaving the
COOKIE-ECHO to be processed without a valid auth_chunk for
deferred verification.

Discard the AUTH chunk early via pdiscard when skb_clone() fails,
so that the receive loop can continue processing remaining chunks
in the inqueue instead of stalling the entire packet.  

Hi Xin Long, should we apply this or it's no longer worth it after
8e04823c120b ?
 

Apply it to net-next.git.

Thanks!

So sending patches with wrong in-reply-to doesn't require repost?

If patchwork ingests the series correctly (which is usually does 
for single patch postings) there's no need to resend. It's mostly 
a convenience thing for maintainers since we try to process patches
from oldest and the threading makes the sort harder.
