net: marvell: prestera: Propagate nh state from hw to kernel
We poll nexthops in HW and call for each active nexthop appropriate neighbour. Also we provide implicity neighbour resolving. For example, user have added nexthop route: # ip route add 5.5.5.5 via 1.1.1.2 But neighbour 1.1.1.2 doesn't exist. In this case we will try to call neigh_event_send, even if there is no traffic. This is useful, when you have add route, which will be used after some time but with a lot of traffic (burst). So, we has prepared, offloaded route in advance.

kcfi updates for v6.1-rc1
This replaces the prior support for Clang's standard Control Flow
Integrity (CFI) instrumentation, which has required a lot of special
conditions (e.g. LTO) and work-arounds. The current implementation
("Kernel CFI") is specific to C, directly designed for the Linux kernel,
and takes advantage of architectural features like x86's IBT. This
series retains arm64 support and adds x86 support. Additional "generic"
architectural support is expected soon:

net/mlx5e: xsk: Optimize for unaligned mode with 3072-byte frames
When XSK frame size is 3072 (or another power of two multiplied by 3), KLM mechanism for NIC virtual memory page mapping can be optimized by replacing it with KSM. Before this change, two KLM entries were needed to map an XSK frame that is not a power of two: one entry maps the UMEM memory up to the frame length, the other maps the rest of the stride to the garbage page. When the frame length divided by 3 is a power of two, it can be mapped using 3 KSM entries, and the fourth will map the rest of the stride to the garbage page. All 4 KSM entries are of the same size, which allows for a much faster lookup. Frame size 3072 is useful in certain use cases, because it allows packing 4 frames into 3 pages. Generally speaking, other frame sizes equal to PAGE_SIZE minus a power of two can be optimized in a similar way, but it will require many more KSMs per frame, which slows down UMRs a little bit, but more importantly may hit the limit for the maximum number of KSM entries.

net/mlx5e: xsk: Print a warning in slow configurations
On striding RQ, when the XSK frame size doesn't match the MKey page size, KLM is used for memory mappings, which is a slower mechanism than MTT or KSM. It may happen in two cases: 1. Frame size is not a power of two (only possible in the unaligned mode of XSK). 2. Frame size is 2048 bytes, and the firmware doesn't support MKey pages smaller than 4096 bytes. Depending on the case, print a warning and recommend to disable striding RQ or upgrade the firmware.

net/mlx5e: xsk: Use KLM to protect frame overrun in unaligned mode
XSK RQs support striding RQ linear mode, but the stride size may be bigger than the XSK frame size, because: 1. The stride size must be a power of two. 2. The stride size must be equal to the UMR page size. Each XSK frame is treated as a separate page, because they aren't necessarily adjacent in physical memory, so the driver can't put more than one stride per page. 3. The minimal MTT page size is 4096 on older firmware. That means that if XSK frame size is 2048 or not a power of two, the strides may be bigger than XSK frames. Normally, it's not a problem if the hardware enforces the MTU. However, traffic between vports skips the hardware MTU check, and oversized packets may be received. If an oversized packet is bigger than the XSK frame but not bigger than the stride, it will cause overwriting of the adjacent UMEM region. If the packet takes more than one stride, they can be recycled for reuse, so it's not a problem when the XSK frame size matches the stride size. Work around the above issue by leveraging KLM to make a more fine-grained mapping. The beginning of each stride is mapped to the frame memory, and the padding up to the closest power of two is mapped to the overflow page that doesn't belong to UMEM. This way, application data corruption won't happen upon receiving packets bigger than MTU.

Ensure that there is always an even amount of MTTs in a UMR WQE, so that complete octwords are formed, and no garbage is mapped.

net/mlx5e: xsk: Improve need_wakeup logic
XSK need_wakeup mechanism allows the driver to stop busy waiting for buffers when the fill ring is empty, yield to the application and signal it that the driver needs to be waken up after the application refills the fill ring. Add protection against the race condition on the RX (refill) side: if the application refills buffers after xskrq->post_wqes is called, but before mlx5e_xsk_update_rx_wakeup, NAPI will exit, skipping taking these buffers to the hardware WQ, and the application won't wake it up again.

net: mvpp2: fix mvpp2 debugfs leak
When mvpp2 is unloaded, the driver specific debugfs directory is not
removed, which technically leads to a memory leak. However, this
directory is only created when the first device is probed, so the
hardware is present. Removing the module is only something a developer
would to when e.g. testing out changes, so the module would be
reloaded. So this memory leak is minor.
The original attempt in commit fe2c9c61f668 ("net: mvpp2: debugfs: fix
memory leak when using debugfs_lookup()") that was labelled as a memory
leak fix was not, it fixed a refcount leak, but in doing so created a
problem when the module is reloaded - the directory already exists, but
mvpp2_root is NULL, so we lose all debugfs entries. This fix has been
reverted.
This is the alternative fix, where we remove the offending directory
whenever the driver is unloaded.
Fixes: 21da57a23125 ("net: mvpp2: add a debugfs interface for the Header Parser")

net: ipa: update comments
This patch just updates comments throughout the IPA code. Transaction state is now tracked using indexes into an array rather than linked lists, and a few comments refer to the "old way" of doing things. The description of how transactions are used was changed to refer to "operations" rather than "commands", to (hopefully) remove a possible ambiguity. IPA register offsets and fields are now handled differently as well, and the register documentation is updated to better describe the code. A few minor updates to comments were made (e.g., adding a missing word, fixing a typo or punctuation, etc.). Finally, the local macro atomic_dec_not_zero() is no longer used, so it is deleted.

net: lan966x: Fix return type of lan966x_port_xmit
The ndo_start_xmit field in net_device_ops is expected to be of type netdev_tx_t (*ndo_start_xmit)(struct sk_buff *skb, struct net_device *dev). The mismatched return type breaks forward edge kCFI since the underlying function definition does not match the function hook definition. The return type of lan966x_port_xmit should be changed from int to netdev_tx_t.

Rust introduction for v6.1-rc1

There's not a huge amount of activity in the docs tree this time around,
but a few significant changes even so:
- A complete rewriting of the top-level index.rst file, which mostly
reflects itself in a redone top page in the HTML-rendered docs. The hope
is that the new organization will be a friendlier starting point for
both users and developers.
- Some math-rendering improvements.
- A coding-style.rst update on the use of BUG() and WARN()
- A big maintainer-PHP guide update.
- Some code-of-conduct updates
- More Chinese translation work
Plus the usual pile of typo fixes, corrections, and updates.

RCU pull request for v6.1
This pull request contains the following branches: doc.2022.08.31b: Documentation updates. This is the first in a series from an ongoing review of the RCU documentation. "Why are people thinking -that- about RCU? Oh. Because that is an entirely reasonable interpretation of its documentation." fixes.2022.08.31b: Miscellaneous fixes. kvfree.2022.08.31b: Improved memory allocation and heuristics. nocb.2022.09.01a: Improve rcu_nocbs diagnostic output. poll.2022.08.31b: Add full-sized polled RCU grace period state values. These are the same size as an rcu_head structure, which is double that of the traditional unsigned long state values that may still be obtained from et_state_synchronize_rcu(). The added size avoids missing overlapping grace periods. This benefit is that call_rcu() can be replaced by polling, which can be attractive in situations where RCU-protected data is aged out of memory. Early in the series, the size of this state value is three unsigned longs. Later in the series, the synchronize_rcu() and synchronize_rcu_expedited() fastpaths are reworked to permit the full state to be represented by only two unsigned longs. This reworking slows these two functions down in SMP kernels running either on single-CPU systems or on systems with all but one CPU offlined, but this should not be a significant problem. And if it somehow becomes a problem in some yet-as-unforeseen situations, three-value state values can be provided for only those situations. Finally, a pair of functions named same_state_synchronize_rcu() and same_state_synchronize_rcu_full() allow grace-period state values to be compared for equality. This permits users to maintain lists of data structures having the same state value, removing the need for per-data-structure grace-period state values, thus decreasing memory footprint. poll-srcu.2022.08.31b: Polled SRCU grace-period updates, including adding tests to rcutorture and reducing the incidence of Tiny SRCU grace-period-state counter wrap. tasks.2022.08.31b: Improve Tasks RCU diagnostics and quiescent-state detection. -----BEGIN PGP SIGNATURE----- iQJHBAABCgAxFiEEbK7UrM+RBIrCoViJnr8S83LZ+4wFAmM3bxQTHHBhdWxtY2tA a2VybmVsLm9yZwAKCRCevxLzctn7jC0zD/0cPe9Nl3LPKVTqDN8wWG6SUOHcwQrg dLBUo1pbBh3mK3HcHzwl1iIF7gd2nmKN7UT3m+C+qv+N3Q9ej9K+MutGThCiRvNT A56TDYU9I1xfqoQ25E9TL7nqty818rtYYMl36Rw8epcLKHo/It9MFODb5kEBY5ir P5UaIK2D4heHfJL6Di8JDq9vC5a/NlNIIkiIj7lUB+px0FpVW0dUqmnWbIOE74YH OBGJ/Mxn6KDO4WeFO0v0DxVaBTLd+khu6W0JspI0szOO6iyTqiDCGE5EqkEdcs5I Fk9WCifdo9nrQG0LPIuEBv0YnwNfGbe5nYXupAmGFb3tdCbjkM+W0UBUE032nXog 3E6m5FEBD1XGQttScFHm70kYssa+xI7khGb9/ZFoYN/QW28oWqwfnx6+eAZGxPNS AZx6pc2bebg8sOUhkz/Sv+qMH7CQgIgcMR66SKl5SdT1Onaig45sgdUuC23BshgG oEdDxvK7vexFQT6q0oqU8LAO/CVKdyVIswt3pB6CUmn8yNgSo+qDZzlEHt0gPdMY 4Xa1jnNtOHobDnI4g0JMdVqAujByrRq74ZsVW96hdedKrA0r9y462jnVBm9tqW68 lu0Lw9WLif2kw0lMY8Q59zqTL+fB8TdNiZrHoqefwvQ/ZrvinfHGSblcrS8zAhX3 4oVwCUs9pPQRMA== =AZPZ -----END PGP SIGNATURE----- Merge tag 'rcu.2022.09.30a' of git://git.kernel.org/pub/scm/linux/kernel/git/paulmck/linux-rcu Pull RCU updates from Paul McKenney: - Documentation updates.
