We want to add reference counting for FDB entries in cross-chip
topologies, and in order for that to have any chance of working and not
be unbalanced (leading to entries which are never deleted), we need to
ensure that higher layers are sane, because if they aren't, it's garbage
in, garbage out.
For example, if we add a bridge FDB entry twice, the bridge properly
errors out:
$ bridge fdb add dev swp0 00:01:02:03:04:07 master static
$ bridge fdb add dev swp0 00:01:02:03:04:07 master static
RTNETLINK answers: File exists
However, the same thing cannot be said about the bridge bypass
operations:
$ bridge fdb add dev swp0 00:01:02:03:04:07
$ bridge fdb add dev swp0 00:01:02:03:04:07
$ bridge fdb add dev swp0 00:01:02:03:04:07
$ bridge fdb add dev swp0 00:01:02:03:04:07
$ echo $?
0
But one 'bridge fdb del' is enough to remove the entry, no matter how
many times it was added.
The bridge bypass operations are impossible to maintain in these
circumstances and lack of support for reference counting the cross-chip
notifiers is holding us back from making further progress, so just drop
support for them. The only way left for users to install static bridge
FDB entries is the proper one, using the "master static" flags.
With this change, rtnl_fdb_add() falls back to calling
ndo_dflt_fdb_add() which uses the duplicate-exclusive variant of
dev_uc_add(): dev_uc_add_excl(). Because DSA does not (yet) declare
IFF_UNICAST_FLT, this results in us going to promiscuous mode:
$ bridge fdb add dev swp0 00:01:02:03:04:05
[ 28.206743] device swp0 entered promiscuous mode
$ bridge fdb add dev swp0 00:01:02:03:04:05
RTNETLINK answers: File exists
So even if it does not completely fail, there is at least some indication
that it is behaving differently from before, and closer to user space
expectations, I would argue (the lack of a "local|static" specifier
defaults to "local", or "host-only", so dev_uc_add() is a reasonable
default implementation). If the generic implementation of .ndo_fdb_add
provided by Vlad Yasevich is a proof of anything, it only proves that
the implementation provided by DSA was always wrong, by not looking at
"ndm->ndm_state & NUD_NOARP" (the "static" flag which means that the FDB
entry points outwards) and "ndm->ndm_state & NUD_PERMANENT" (the "local"
flag which means that the FDB entry points towards the host). It all
used to mean the same thing to DSA.
Update the documentation so that the users are not confused about what's
going on.

These is no need to wait for 'interval' period for the next probe
if the last probe is already acked in search state. The 'interval'
period waiting should be only for probe failure timeout and the
current pmtu check when it's in search complete state.
This change will shorten the probe time a lot in search state, and
also fix the document accordingly.

This patch is meant to start the initiative to document libbpf.
It includes .rst files which are text documentation describing building,
API naming convention, as well as an index to generated API documentation.
In this approach the generated API documentation is enabled by the kernels
existing kernel documentation system which uses sphinx. The resulting docs
would then be synced to kernel.org/doc
You can test this by running `make htmldocs` and serving the html in
Documentation/output. Since libbpf does not yet have comments in kernel
doc format, see kernel.org/doc/html/latest/doc-guide/kernel-doc.html for
an example so you can test this.
The advantage of this approach is to use the existing sphinx
infrastructure that the kernel has, and have libbpf docs in
the same place as everything else.
The current plan is to have the libbpf mirror sync the generated docs
and version them based on the libbpf releases which are cut on github.
This patch includes the addition of libbpf_api.rst which pulls comment
documentation from header files in libbpf under tools/lib/bpf/. The comment
docs would be of the standard kernel doc format.

Patch series "Actually fix freelist pointer vs redzoning", v4.
This fixes redzoning vs the freelist pointer (both for middle-position
and very small caches). Both are "theoretical" fixes, in that I see no
evidence of such small-sized caches actually be used in the kernel, but
that's no reason to let the bugs continue to exist, especially since
people doing local development keep tripping over it. :)
This patch (of 3):
Instead of repeating "Redzone" and "Poison", clarify which sides of
those zones got tripped. Additionally fix column alignment in the
trailer.
Before:
BUG test (Tainted: G B ): Redzone overwritten
...
Redzone (____ptrval____): bb bb bb bb bb bb bb bb ........
Object (____ptrval____): f6 f4 a5 40 1d e8 ...@..
Redzone (____ptrval____): 1a aa ..

After:

Add IPA device attributes to expose information known by the IPA
driver about the hardware and its configuration.
All pointers used to display these attribute values (i.e., IPA
pointer and endpoint pointers) will have been initialized by the
time IPA probe has completed, so they may be safely dereferenced.

Some really really weird switches just couldn't decide whether to use a
normal or a tail tagger, so they just did both.
This creates problems for DSA, because we only have the concept of an
'overhead' which can be applied to the headroom or to the tailroom of
the skb (like for example during the central TX reallocation procedure),
depending on the value of bool tail_tag, but not to both.
We need to generalize DSA to cater for these odd switches by
transforming the 'overhead / tail_tag' pair into 'needed_headroom /
needed_tailroom'.
The DSA master's MTU is increased to account for both.
The flow dissector code is modified such that it only calls the DSA
adjustment callback if the tagger has a non-zero header length.
Taggers are trivially modified to declare either needed_headroom or
needed_tailroom, based on the tail_tag value that they currently
declare.

Move private bridge structures to dedicated headers that is accessible to
bridge tracepoint header. Implemented following tracepoints:
- Initialize FDB entry.
- Refresh FDB entry.
- Cleanup FDB entry.
- Create VLAN.
- Cleanup VLAN.
- Attach port to bridge.
- Detach port from bridge.
Usage example:
># cd /sys/kernel/debug/tracing
># echo mlx5:mlx5_esw_bridge_fdb_entry_init >> set_event
># cat trace

Implement support for pushing vlan header into untagged packet on ingress
of port that has pvid configured and support for popping vlan on egress of
port that has the matching vlan configured as untagged. To support such
configurations packet reformat contexts of {INSERT|REMOVE}_HEADER types are
created per such vlan and saved to struct mlx5_esw_bridge_vlan which allows
all FDB entries on particular vlan to share single packet reformat
instance. When initializing FDB entries with pvid or untagged vlan type set
its mlx5_flow_act->pkt_reformat action accordingly.
Flush all flows when removing vlan from port. This is necessary because
even though software bridge removes all FDB entries before removing their
vlan, mlx5 bridge implementation deletes their corresponding flow entries
from hardware in asynchronous workqueue task, which will cause firmware
error if vlan packet reformat context is deleted before all flows that
point to it.

Hardware supported by mlx5 driver doesn't provide learning and requires the
driver to emulate all switch-like behavior in software. As such, all
packets by default go through miss path, appear on representor and get to
software bridge, if it is the upper device of the representor. This causes
bridge to process packet in software, learn the MAC address to FDB and send
SWITCHDEV_FDB_ADD_TO_DEVICE event to all subscribers.
In order to offload FDB entries in mlx5, register switchdev notifier
callback and implement support for both 'added_by_user' and dynamic FDB
entry SWITCHDEV_FDB_ADD_TO_DEVICE events asynchronously using new
mlx5_esw_bridge_offloads->wq ordered workqueue. In workqueue callback
offload the ingress rule (matching FDB entry MAC as packet source MAC) and
egress table rule (matching FDB entry MAC as destination MAC). For ingress
table rule also match source vport to ensure that only traffic coming from
expected bridge port is matched by offloaded rule. Save all the relevant
FDB entry data in struct mlx5_esw_bridge_fdb_entry instance and insert the
instance in new mlx5_esw_bridge->fdb_list list (for traversing all entries
by software ageing implementation in following patch) and in new
mlx5_esw_bridge->fdb_ht hash table for fast retrieval. Notify the bridge
that FDB entry has been offloaded by sending SWITCHDEV_FDB_OFFLOADED
notification.
Delete FDB entry on reception of SWITCHDEV_FDB_DEL_TO_DEVICE event.
