Merge tag 'rcu.2022.09.30a' of git://git./linux/kernel/git/paulmck/linux-rcu
Pull RCU updates from Paul McKenney:
- 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."
- Miscellaneous fixes.
- Improved memory allocation and heuristics.
- Improve rcu_nocbs diagnostic output.
- 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 fastpaths in synchronize_rcu() and
synchronize_rcu_expedited() 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.
- Polled SRCU grace-period updates, including adding tests to
rcutorture and reducing the incidence of Tiny SRCU grace-period-state
counter wrap.
- Improve Tasks RCU diagnostics and quiescent-state detection.

This is because __inet_hash_connect() uses get_random_once()

after commit
4c2c8f03a5ab ("tcp: increase source port perturb table to 2^16")
get_random_once() uses DO_ONCE(), which block hard irqs for the duration

====================
net: Introduce macsec hardware offload for cn10k platform
CN10K-B and CNF10K-B variaints of CN10K silicon has macsec block(MCS)
to encrypt and decrypt packets at MAC/hardware level. This block is a
global resource with hardware resources like SecYs, SCs and SAs
and is in between NIX block and RPM LMAC. CN10K-B silicon has only
one MCS block which receives packets from all LMACS whereas
CNF10K-B has seven MCS blocks for seven LMACs. Both MCS blocks are
similar in operation except for few register offsets and some
configurations require writing to different registers. This patchset
introduces macsec hardware offloading support. AF driver manages hardware
resources and PF driver consumes them when macsec hardware offloading
is needed.
Patch 1 adds basic pci driver for both CN10K-B and CNF10K-B
silicons and initializes hardware block.
Patches 2 and 3 adds mailboxes to init, reset and manage
resources of the MCS block
Patch 4 adds a low priority rule in MCS TCAM so that the
traffic which do not need macsec processing can be sent/received
Patch 5 adds macsec stats collection support
Patch 6 adds interrupt handling support and any event in which
AF consumer is interested can be notified via mbox notification
Patch 7 adds debugfs support which helps in debugging packet
path
Patch 8 introduces macsec hardware offload feature for
PF netdev driver.

This patch introduces the macsec offload feature to cn10k
PF netdev driver. The macsec offload ops like adding, deleting
and updating SecYs, SCs, SAs and stats are supported. XPN support
will be added in later patches. Some stats use same counter in hardware
which means based on the SecY mode the same counter represents different
stat. Hence when SecY mode/policy is changed then snapshot of current
stats are captured. Also there is no provision to specify the unique
flow-id/SCI per packet to hardware hence different mac address needs to
be set for macsec interfaces.

Hardware triggers an interrupt for events like PN wrap to zero,
PN crosses set threshold. This interrupt is received
by the MCS_AF. MCS AF then finds the PF/VF to which SA is mapped

PF/VF using mcs_intr_cfg mbox can configure the list

We can accommodate a such user by extending the fastclose

Some of the patches I've taken from Russell King's net-queue [1]

The important change from my previous attempts are:
- I am including the changes needed to phylink and marvell10g driver,
so that the 88X3310 PHY is configured to use PHY modes supported by
the host (the PHY defaults to use 10gbase-r only on host's side)
- I have changed the patch that informs phylib about the interfaces
supported by the host (patch 5 of this series): it now fills in the
phydev->host_interfaces member only when connecting a PHY that is
inside a SFP module. This may change in the future.

This adds support for multigig copper SFP modules from RollBall/Hilink.
These modules have a specific way to access clause 45 registers of the
internal PHY.
We also need to wait at least 22 seconds after deasserting TX disable
before accessing the PHY. The code waits for 25 seconds just to be sure.

Some multigig SFPs from RollBall and Hilink do not expose functional
MDIO access to the internal PHY of the SFP via I2C address 0x56
(although there seems to be read-only clause 22 access on this address).
Instead these SFPs PHY can be accessed via I2C via the SFP Enhanced
Digital Diagnostic Interface - I2C address 0x51. The SFP_PAGE has to be

This extends the mdio-i2c driver to support this protocol by adding a

net: phy: marvell10g: select host interface configuration
Select the host interface configuration according to the capabilities of
the host if the host provided them. This is currently provided only when
connecting PHY that is inside a SFP.
The PHY supports several configurations of host communication:
- always communicate with host in 10gbase-r, even if copper speed is
lower (rate matching mode),
- the same as above but use xaui/rxaui instead of 10gbase-r,
- switch host SerDes mode between 10gbase-r, 5gbase-r, 2500base-x and
sgmii according to copper speed,
- the same as above but use xaui/rxaui instead of 10gbase-r.
This mode of host communication, called MACTYPE, is by default selected
by strapping pins, but it can be changed in software.
This adds support for selecting this mode according to which modes are
supported by the host.
This allows the kernel to:
- support SFP modules with 88X33X0 or 88E21X0 inside them
Note: we use mv3310_select_mactype() for both 88X3310 and 88X3340,
although 88X3340 does not support XAUI. This is not a problem because
88X3340 does not declare XAUI in it's supported_interfaces, and so this

We can reproduce this issue by creating two AF_UNIX SOCK_STREAM sockets,
send()ing an OOB skb to each other, and close()ing them without consuming
the OOB skbs.
int skpair[2];
socketpair(AF_UNIX, SOCK_STREAM, 0, skpair);
send(skpair[0], "x", 1, MSG_OOB);
send(skpair[1], "x", 1, MSG_OOB);
close(skpair[0]);
close(skpair[1]);
Currently, we free an OOB skb in unix_sock_destructor() which is called via
__sk_free(), but it's too late because the receiver's unix_sk(sk)->oob_skb
is accounted against the sender's sk->sk_wmem_alloc and __sk_free() is
called only when sk->sk_wmem_alloc is 0.
In the repro sequences, we do not consume the OOB skb, so both two sk's
sock_put() never reach __sk_free() due to the positive sk->sk_wmem_alloc.
Then, no one can consume the OOB skb nor call __sk_free(), and we finally
leak the two whole sk.
Thus, we must free the unconsumed OOB skb earlier when close()ing the
socket.

Saeed Mahameed says:
====================
mlx5 xsk updates part3 2022-09-30
The gist of this 4 part series is in this patchset's last patch
This series contains performance optimizations. XSK starts using the
batching allocator, and XSK data path gets separated from the regular
RX, allowing to drop some branches not relevant for non-XSK use cases.
Some minor optimizations for indirect calls and need_wakeup are also
included.
Other than that, this series adds a few features to the mlx5e
implementation of XSK:
1. XDP metadata support on XSK RQs.
2. RSS contexts support for XSK RQs.
3. Some other optimizations
4. Last but not least, change the queuing scheme, so that XSK RQs no longer
use higher indices, but replace the regular RQs.
Maxim Says:
==========
In the initial implementation of XSK in mlx5e, XSK RQs coexisted with
regular RQs in the same channel. The main idea was to allow RSS work the
same for regular traffic, without need to reconfigure RSS to exclude XSK
queues.
However, this scheme didn't prove to be beneficial, mainly because of
incompatibility with other vendors. Some tools don't properly support
using higher indices for XSK queues, some tools get confused with the
double amount of RQs exposed in sysfs. Some use cases are purely XSK,
and allocating the same amount of unused regular RQs is a waste of
resources.
This commit changes the queuing scheme to the standard one, where XSK
RQs replace regular RQs on the channels where XSK sockets are open. Two
RQs still exist in the channel to allow failsafe disable of XSK, but
only one is exposed at a time. The next commit will achieve the desired
memory save by flushing the buffers when the regular RQ is unused.
As the result of this transition:
1. It's possible to use RSS contexts over XSK RQs.
2. It's possible to dedicate all queues to XSK.

net/mlx5e: xsk: Use queue indices starting from 0 for XSK queues
In the initial implementation of XSK in mlx5e, XSK RQs coexisted with
regular RQs in the same channel. The main idea was to allow RSS work the
same for regular traffic, without need to reconfigure RSS to exclude XSK
queues.
However, this scheme didn't prove to be beneficial, mainly because of
incompatibility with other vendors. Some tools don't properly support
using higher indices for XSK queues, some tools get confused with the
double amount of RQs exposed in sysfs. Some use cases are purely XSK,
and allocating the same amount of unused regular RQs is a waste of
resources.
This commit changes the queuing scheme to the standard one, where XSK
RQs replace regular RQs on the channels where XSK sockets are open. Two
RQs still exist in the channel to allow failsafe disable of XSK, but
only one is exposed at a time. The next commit will achieve the desired
memory save by flushing the buffers when the regular RQ is unused.
As the result of this transition:
1. It's possible to use RSS contexts over XSK RQs.
2. It's possible to dedicate all queues to XSK.
3. When XSK RQs coexist with regular RQs, the admin should make sure no
unwanted traffic goes into XSK RQs by either excluding them from RSS or
settings up the XDP program to return XDP_PASS for non-XSK traffic.
4. When using a mixed fleet of mlx5e devices and other netdevs, the same
configuration can be applied. If the application supports the fallback
to copy mode on unsupported drivers, it will work too.

net/mlx5e: Optimize RQ page deallocation
mlx5e_free_rx_mpwqe loops over all pages of a MPWQE, calling
mlx5e_page_release for ones that are not scheduled for XDP_TX or
XDP_REDIRECT; and mlx5e_page_release checks whether it's an XSK RQ or a
regular one for each page/XSK frame. This check can be moved outside the
loop to reduce the number of branches.
mlx5e_free_rx_wqe loops over all fragments, calling mlx5e_page_release
for the ones that are last in a page; and mlx5e_page_release checks
whether it's an XSK RQ or a regular one for each fragment. Using the
fact that XSK doesn't support multiple fragments, it can be optimized
for both XSK and regular usages:
1. Make an early check for XSK and call its deallocator directly, saving
3 branches (loop condition, frag->last_in_page and selection of
deallocator).
2. Call the regular deallocator directly in the non-XSK case, saving a
branch per fragment, except the first one.

Legacy RQ allocates WQEs in batches. If the batch allocation fails, the
pages of the allocated part are released. This commit changes this
behavior to allow to use the pages that have been already allocated.
After this change, we need to be careful about indexing rq->wqe.frags[].
The WQ size is a power of two that divides by wqe_bulk (8), and the old
code used whole bulks, which allowed to use indices [8*K; 8*K+7] without
overflowing. Now that the bulks may be partial, the range can start at
any location (not only at 8*K), so we need to wrap them around to avoid
out-of-bounds array access.

net/mlx5e: Introduce wqe_index_mask for legacy RQ
When fragments of different WQEs share the same page, mlx5e_post_rx_wqes
must wait until the old WQE stops using the page, only then the new WQE
can allocate the new page. Essentially, it means that if WQE index i is
still in use, the allocation must stop before `i % bulk`, where bulk is
the number of WQEs that may share the same page.
As bulk is always a power of two, `i % bulk = i & (bulk - 1)`, and the
new wqe_index_mask field will be equal to `bulk - 1`.
At the same time, wqe_bulk remains for optimization purposes and stores
`max(bulk, 8)`, which allows to skip the allocation until we have at
least 8 WQEs free.

not very useful, because:
0. Both XSK setup and netdev state transitions take the same state_lock

1. If the netdev is up, xsk_is_bound can return true only when

mlx5e_xsk_wakeup is only called when xsk_is_bound is true.
2. If the XSK socket is bound, and the netdev is going up or down,
mlx5e_xsk_wakeup can take one of two branches, depending on the return
value of napi_if_scheduled_mark_missed:
2.1. True means one of two things: either NAPI was enabled at this
point, which means MLX5E_CHANNEL_STATE_XSK was also set; or NAPI was
disabled, and nothing really happened.
2.2. False means that NAPI was enabled by this point, which also implies
MLX5E_CHANNEL_STATE_XSK was set. Additionally, mlx5e_xsk_wakeup contains
a following check for MLX5E_SQ_STATE_ENABLED on async_icosq, and this
