are represented as having "True" as value in pyroute2.

Add a test case into the netlink checks that will show the number of
nested action recursions won't exceed 16. Going to 17 on a small
clone call isn't enough to exhaust the stack on (most) systems, so
it should be safe to run even on systems that don't have the fix
applied.

Pull networking fixes from Jakub Kicinski:
"Including fixes from bluetooth, netfilter, WiFi.

Feels like an up-tick in regression fixes, mostly for older releases.
The hfsc fix, tcp_disconnect() and Intel WWAN fixes stand out as
fairly clear-cut user reported regressions. The mlx5 DMA bug was
causing strife for 390x folks. The fixes themselves are not
particularly scary, tho. No open investigations / outstanding reports
at the time of writing.

Current release - regressions:

- eth: mlx5: perform DMA operations in the right locations, make
devices usable on s390x, again

- sched: sch_hfsc: upgrade 'rt' to 'sc' when it becomes a inner
curve, previous fix of rejecting invalid config broke some scripts

- rfkill: reduce data->mtx scope in rfkill_fop_open, avoid deadlock

- revert "ethtool: Fix mod state of verbose no_mask bitset", needs
more work

Current release - new code bugs:

- tcp: fix listen() warning with v4-mapped-v6 address

Previous releases - regressions:

- tcp: allow tcp_disconnect() again when threads are waiting, it was
denied to plug a constant source of bugs but turns out .NET depends
on it

- eth: mlx5: fix double-free if buffer refill fails under OOM

- revert "net: wwan: iosm: enable runtime pm support for 7560", it's
causing regressions and the WWAN team at Intel disappeared

- tcp: tsq: relax tcp_small_queue_check() when rtx queue contains a
single skb, fix single-stream perf regression on some devices

Previous releases - always broken:

- Bluetooth:
- fix issues in legacy BR/EDR PIN code pairing
- correctly bounds check and pad HCI_MON_NEW_INDEX name

- netfilter:
- more fixes / follow ups for the large "commit protocol" rework,
which went in as a fix to 6.5
- fix null-derefs on netlink attrs which user may not pass in

- tcp: fix excessive TLP and RACK timeouts from HZ rounding (bless
Debian for keeping HZ=250 alive)

- net: more strict VIRTIO_NET_HDR_GSO_UDP_L4 validation, prevent
letting frankenstein UDP super-frames from getting into the stack

- net: fix interface altnames when ifc moves to a new namespace

- eth: qed: fix the size of the RX buffers

- mptcp: avoid sending RST when closing the initial subflow"

Message-ID: <20231011194939.704565-1-aconole@redhat.com> (raw)

A number of corner cases were caught when trying to run the selftests on
older systems. Missed skip conditions, some error cases, and outdated
python setups would all report failures but the issue would actually be
related to some other condition rather than the selftest suite.

Address these individual cases.

selftests: openvswitch: Add version check for pyroute2

Paolo Abeni reports that on some systems the pyroute2 version isn't
new enough to run the test suite. Ensure that we support a minimum
version of 0.6 for all cases (which does include the existing ones).
The 0.6.1 version was released in May of 2021, so should be
propagated to most installations at this point.

The alternative that Paolo proposed was to only skip when the
add-flow is being run. This would be okay for most cases, except
if a future test case is added that needs to do flow dump without
an associated add (just guessing). In that case, it could also be
broken and we would need additional skip logic anyway. Just draw
a line in the sand now.

Merge branch 'ovs-drop-reasons'

Adrian Moreno says:

====================
openvswitch: add drop reasons

There is currently a gap in drop visibility in the openvswitch module.
This series tries to improve this by adding a new drop reason subsystem
for OVS.

Apart from adding a new drop reasson subsystem and some common drop
reasons, this series takes Eric's preliminary work [1] on adding an
explicit drop action and integrates it into the same subsystem.

A limitation of this series is that it does not report upcall errors.
The reason is that there could be many sources of upcall drops and the
most common one, which is the netlink buffer overflow, cannot be
reported via kfree_skb() because the skb is freed in the netlink layer
(see [2]). Therefore, using a reason for the rare events and not the
common one would be even more misleading. I'd propose we add (in a
follow up patch) a tracepoint to better report upcall errors.

- Moved the ovs-dpctl.py changes from patch 7/7 to 3/7
- Added a test to ensure actions following a drop are rejected

- Added a drop reason for action errors

net: openvswitch: add explicit drop action

From: Eric Garver <eric@garver.life>

This adds an explicit drop action. This is used by OVS to drop packets
for which it cannot determine what to do. An explicit action in the
kernel allows passing the reason _why_ the packet is being dropped or
zero to indicate no particular error happened (i.e: OVS intentionally
dropped the packet).

Since the error codes coming from userspace mean nothing for the kernel,
we squash all of them into only two drop reasons:
- OVS_DROP_EXPLICIT_WITH_ERROR to indicate a non-zero value was passed
- OVS_DROP_EXPLICIT to indicate a zero value was passed (no error)

e.g. trace all OVS dropped skbs

# perf trace -e skb:kfree_skb --filter="reason >= 0x30000"
[..]
106.023 ping/2465 skb:kfree_skb(skbaddr: 0xffffa0e8765f2000, \
location:0xffffffffc0d9b462, protocol: 2048, reason: 196611)

reason: 196611 --> 0x30003 (OVS_DROP_EXPLICIT)

Also, this patch allows ovs-dpctl.py to add explicit drop actions as:
"drop" -> implicit empty-action drop
"drop(0)" -> explicit non-error action drop
"drop(42)" -> explicit error action drop

The openvswitch selftests currently contain a few cases for managing the

the control path.

Add the ability to program some of the more common flows with actions. This
can be improved overtime to include regression testing, etc.

selftests: openvswitch: add an initial flow programming case

The openvswitch self-tests can test much of the control side of
the module (ie: what a vswitchd implementation would process),
but the actual packet forwarding cases aren't supported, making
the testing of limited value.

Add some flow parsing and an initial ARP based test case using
arping utility. This lets us display flows, add some basic
output flows with simple matches, and test against a known good
forwarding case.
