- The no-data cap (patch 1) is a prerequisite, not a stand-alone fix.
Once control records reach read_sock, a record carrying no payload
stops advancing the caller's read descriptor, so a peer streaming
such records would pin the socket lock and the kernel receive
context for as long as the flood lasts. Bounding consecutive
no-data records supplies the return boundary a system call would
otherwise provide. The cap is scoped to tls_sw_read_sock() alone:
splice and recvmsg run in the caller's own context, reschedule, and
drop the lock on return, so they need nothing.
Is it just me or this is incomprehensible slop? Run on sentences
full of terms no kernel developer would use?
It makes sense to me. Which terms do you have trouble with?
Patch 1 is moving to a pre-requisite series, so this can be dropped
from the cover letter.
Did you write this? If not what model did you use?
