From: Geliang Tang <geliang.tang@suse.com>
If the initial subflow has been removed, we cannot know without checking
other counters, e.g. ss -ti <filter> | grep -c tcp-ulp-mptcp or
getsockopt(SOL_MPTCP, MPTCP_FULL_INFO, ...) (or others except MPTCP_INFO
of course) and then check mptcp_subflow_data->num_subflows to get the
total amount of subflows.
This patch adds a new counter mptcpi_subflows_total in mptcpi_flags to
store the total amount of subflows, including the initial one. A new
helper __mptcp_has_initial_subflow() is added to check whether the
initial subflow has been removed or not. With this helper, we can then
compute the total amount of subflows from mptcp_info by doing something
like:
mptcpi_subflows_total = mptcpi_subflows +
__mptcp_has_initial_subflow(msk).

This patch adds a new helper get_info_value(), using 'sed' command to
parse the value of the given item name in the line with the given keyword,
to make chk_mptcp_info() and pedit_action_pkts() more readable.
Also add another helper evts_get_info() to use get_info_value() to parse
the output of 'pm_nl_ctl events' command, to make all the userspace pm
selftests more readable, both in mptcp_join.sh and userspace_pm.sh.

This patch adds a new helper chk_subflows_total(), in it use the newly
added counter mptcpi_subflows_total to get the "correct" amount of
subflows, including the initial one.
To be compatible with old 'ss' or kernel versions not supporting this
counter, get the total subflows by listing TCP connections that are
MPTCP subflows:
ss -ti state state established state syn-sent state syn-recv |
grep -c tcp-ulp-mptcp.

From: Geliang Tang <geliang.tang@suse.com>
This patch adds a new argument namespace to userspace_pm_add_addr() and
userspace_pm_add_sf() to make these two helper more versatile.
Add two more versatile helpers for userspace pm remove subflow or address:
userspace_pm_rm_addr() and userspace_pm_rm_sf(). The original test helpers
userspace_pm_rm_sf_addr_ns1() and userspace_pm_rm_sf_addr_ns2() can be
replaced by these new helpers.

This patch adds a selftest to create id 0 subflow. Pass id 0 to the
helper userspace_pm_add_sf() to create id 0 subflow. chk_mptcp_info
shows one subflow but chk_subflows_total shows two subflows in each
namespace.

The value of 'err' will not be only '-EINVAL', but can be '0' in some
cases.
So it's better to rename the label 'remove_err' to 'out' to avoid
confusions.

To avoid duplicated code in different MPTCP selftests, we can add
and use helpers defined in mptcp_lib.sh.
Export kill_wait() helper in userspace_pm.sh into mptcp_lib.sh and
rename it as mptcp_lib_kill_wait(). It can be used to instead of
kill_wait() in mptcp_join.sh. Use the new helper in both scripts.

To avoid duplicated code in different MPTCP selftests, we can add
and use helpers defined in mptcp_lib.sh.
is_v6() helper is defined in mptcp_connect.sh, mptcp_join.sh and
mptcp_sockopt.sh, so export it into mptcp_lib.sh and rename it as
mptcp_lib_is_v6(). Use this new helper in all scripts.

To avoid duplicated code in different MPTCP selftests, we can add
and use helpers defined in mptcp_lib.sh.
The helper get_counter() in mptcp_join.sh and get_mib_counter() in
mptcp_connect.sh have the same functionality, export get_counter() into
mptcp_lib.sh and rename it as mptcp_lib_get_counter(). Use this new
helper instead of get_counter() and get_mib_counter().

From: Geliang Tang <geliang.tang@suse.com>
In mptcp_connect.sh we are missing something like "oflag=append"
because this will write "${rem}" bytes at the beginning of the file
where there is already some random bytes. It should write that at
the end.
This patch adds this missing 'oflag=append' flag for 'dd' command in
make_file().

To avoid duplicated code in different MPTCP selftests, we can add
and use helpers defined in mptcp_lib.sh.
make_file() helper in mptcp_sockopt.sh and userspace_pm.sh are the same.
Export it into mptcp_lib.sh and rename it as mptcp_lib_kill_wait(). Use
it in both mptcp_connect.sh and mptcp_join.sh.

To avoid duplicated code in different MPTCP selftests, we can add
and use helpers defined in mptcp_lib.sh.
check_transfer() and print_file_err() helpers are defined both in
mptcp_connect.sh and mptcp_sockopt.sh, export them into mptcp_lib.sh
and rename them with mptcp_lib_ prefix. And use them in all scripts.
Note: In mptcp_sockopt.sh it is OK to drop 'ret=1' in check_transfer()
because it will be set in run_tests() anyway.

From: Geliang Tang <geliang.tang@suse.com>
To avoid duplicated code in different MPTCP selftests, we can add
and use helpers defined in mptcp_lib.sh.
wait_local_port_listen() helper is defined in diag.sh, mptcp_connect.sh,
mptcp_join.sh and simult_flows.sh, export it into mptcp_lib.sh and
rename it with mptcp_lib_ prefix. Use this new helper in all these
scripts.
Note: We only have IPv4 connections in this helper, not looking at IPv6
(tcp6) but that's OK because we only have IPv4 connections here in diag.sh.

I was finalizing the PR already when you posted, sorry :(
## Form letter - net-next-closed
The merge window for v6.7 has begun and we have already posted our pull
request. Therefore net-next is closed for new drivers, features, code
refactoring and optimizations. We are currently accepting bug fixes only.
Please repost when net-next reopens after Nov 12th.
RFC patches sent for review only are obviously welcome at any time.
See: https://www.kernel.org/doc/html/next/process/maintainer-netdev.html#development-cycle
