[Linux-stable-mirror] Patch "tcp: provide timestamps for partial writes" has been added to the 4.9-stable tree

by gregkh＠linuxfoundation.org

This is a note to let you know that I've just added the patch titled tcp: provide timestamps for partial writes to the 4.9-stable tree which can be found at: http://www.kernel.org/git/?p=linux/kernel/git/stable/stable-queue.git;a=sum… The filename of the patch is: tcp-provide-timestamps-for-partial-writes.patch and it can be found in the queue-4.9 subdirectory. If you, or anyone else, feels it should not be added to the stable tree, please let <stable(a)vger.kernel.org> know about it. >From foo@baz Sun Nov 19 11:32:28 CET 2017 From: Soheil Hassas Yeganeh <soheil(a)google.com> Date: Wed, 4 Jan 2017 11:19:34 -0500 Subject: tcp: provide timestamps for partial writes From: Soheil Hassas Yeganeh <soheil(a)google.com> [ Upstream commit ad02c4f547826167a709dab8a89a1caefd2c1f50 ] For TCP sockets, TX timestamps are only captured when the user data is successfully and fully written to the socket. In many cases, however, TCP writes can be partial for which no timestamp is collected. Collect timestamps whenever any user data is (fully or partially) copied into the socket. Pass tcp_write_queue_tail to tcp_tx_timestamp instead of the local skb pointer since it can be set to NULL on the error path. Note that tcp_write_queue_tail can be NULL, even if bytes have been copied to the socket. This is because acknowledgements are being processed in tcp_sendmsg(), and by the time tcp_tx_timestamp is called tcp_write_queue_tail can be NULL. For such cases, this patch does not collect any timestamps (i.e., it is best-effort). This patch is written with suggestions from Willem de Bruijn and Eric Dumazet. Change-log V1 -> V2: - Use sockc.tsflags instead of sk->sk_tsflags. - Use the same code path for normal writes and errors.

In order to prepare for allowing us to follow function prologue macros with an EXPORT_SYMBOL invocation, end the prologue macros (LEAD, NESTED & FEXPORT) with a .insn directive.
