+Subject: mptcp: pr_debug: add missing \n at the end
+To: stable@vger.kernel.org, gregkh@linuxfoundation.org

+Message-ID: <20240903100957.3368081-2-matttbe@kernel.org>
+
+From: "Matthieu Baerts (NGI0)" <matttbe@kernel.org>
+
+commit cb41b195e634d3f1ecfcd845314e64fd4bb3c7aa upstream.
+
+pr_debug() have been added in various places in MPTCP code to help
+developers to debug some situations. With the dynamic debug feature, it
+is easy to enable all or some of them, and asks users to reproduce
+issues with extra debug.
+
+Many of these pr_debug() don't end with a new line, while no 'pr_cont()'
+are used in MPTCP code. So the goal was not to display multiple debug
+messages on one line: they were then not missing the '\n' on purpose.
+Not having the new line at the end causes these messages to be printed
+with a delay, when something else needs to be printed. This issue is not
+visible when many messages need to be printed, but it is annoying and
+confusing when only specific messages are expected, e.g.
+
+ # echo "func mptcp_pm_add_addr_echoed +fmp" \
+ > /sys/kernel/debug/dynamic_debug/control
+ # ./mptcp_join.sh "signal address"; \
+ echo "$(awk '{print $1}' /proc/uptime) - end"; \
+ sleep 5s; \
+ echo "$(awk '{print $1}' /proc/uptime) - restart"; \
+ ./mptcp_join.sh "signal address"
+ 013 signal address
+ (...)
+ 10.75 - end
+ 15.76 - restart
+ 013 signal address
+ [ 10.367935] mptcp:mptcp_pm_add_addr_echoed: MPTCP: msk=(...)
+ (...)
+
+ => a delay of 5 seconds: printed with a 10.36 ts, but after 'restart'
+ which was printed at the 15.76 ts.
+
+The 'Fixes' tag here below points to the first pr_debug() used without
+'\n' in net/mptcp. This patch could be split in many small ones, with
+different Fixes tag, but it doesn't seem worth it, because it is easy to
+re-generate this patch with this simple 'sed' command:
+
+ git grep -l pr_debug -- net/mptcp |
+ xargs sed -i "s/\(pr_debug(\".*[^n]\)\(\"[,)]\)/\1\\\n\2/g"
+
+So in case of conflicts, simply drop the modifications, and launch this
+command.
+
