A lot of networking people were at a conference last week, busy
catching COVID, so relatively short PR. Including fixes from bpf
and netfilter.
Current release - regressions:
- tcp: process the 3rd ACK with sk_socket for TFO and MPTCP
Current release - new code bugs:
- l2tp: protect session IDR and tunnel session list with one lock,
make sure the state is coherent to avoid a warning
- eth: bnxt_en: update xdp_rxq_info in queue restart logic
- eth: airoha: fix location of the MBI_RX_AGE_SEL_MASK field
Previous releases - regressions:
- xsk: require XDP_UMEM_TX_METADATA_LEN to actuate tx_metadata_len,
the field reuses previously un-validated pad
Previous releases - always broken:
- tap/tun: drop short frames to prevent crashes later in the stack
- eth: ice: add a per-VF limit on number of FDIR filters
- af_unix: disable MSG_OOB handling for sockets in sockmap/sockhash

Driver core changes for 6.11-rc1
Here is the big set of driver core changes for 6.11-rc1.
Lots of stuff in here, with not a huge diffstat, but apis are evolving
which required lots of files to be touched. Highlights of the changes
in here are:
- platform remove callback api final fixups (Uwe took many releases to
get here, finally!)
- Rust bindings for basic firmware apis and initial driver-core
interactions. It's not all that useful for a "write a whole driver
in rust" type of thing, but the firmware bindings do help out the
phy rust drivers, and the driver core bindings give a solid base on
which others can start their work. There is still a long way to go
here before we have a multitude of rust drivers being added, but
it's a great first step.
- driver core const api changes. This reached across all bus types,
and there are some fix-ups for some not-common bus types that
linux-next and 0-day testing shook out. This work is being done to
help make the rust bindings more safe, as well as the C code, moving
toward the end-goal of allowing us to put driver structures into
read-only memory. We aren't there yet, but are getting closer.
- minor devres cleanups and fixes found by code inspection
- arch_topology minor changes
- other minor driver core cleanups
All of these have been in linux-next for a very long time with no
reported problems.

ice: Fix recipe read procedure
When ice driver reads recipes from firmware information about
need_pass_l2 and allow_pass_l2 flags is not stored correctly.
Those flags are stored as one bit each in ice_sw_recipe structure.
Because of that, the result of checking a flag has to be casted to bool.
Note that the need_pass_l2 flag currently works correctly, because
it's stored in the first bit.

ice: Add a per-VF limit on number of FDIR filters
While the iavf driver adds a s/w limit (128) on the number of FDIR
filters that the VF can request, a malicious VF driver can request more
than that and exhaust the resources for other VFs.
Add a similar limit in ice.

Networking changes for 6.11. Not much excitement - a handful of large
patchsets (devmem among them) did not make it in time.
Core & protocols
----------------
- Use local_lock in addition to local_bh_disable() to protect per-CPU
resources in networking, a step closer for local_bh_disable() not
to act as a big lock on PREEMPT_RT.
- Use flex array for netdevice priv area, ensure its cache alignment.
- Add a sysctl knob to allow user to specify a default rto_min at socket
init time. Bit of a big hammer but multiple companies were
independently carrying such patch downstream so clearly it's useful.
- Support scheduling transmission of packets based on CLOCK_TAI.
- Un-pin TCP TIMEWAIT timer to avoid it firing on CPUs later cordoned off
using cpusets.
- Support multiple L2TPv3 UDP tunnels using the same 5-tuple address.
- Allow configuration of multipath hash seed, to both allow synchronizing
hashing of two routers, and preventing partial accidental sync.
- Improve TCP compliance with RFC 9293 for simultaneous connect().
- Support sending NAT keepalives in IPsec ESP in UDP states. Userspace
IKE daemon had to do this before, but the kernel can better keep
track of it.
- Support sending supervision HSR frames with MAC addresses stored in
ProxyNodeTable when RedBox (i.e. HSR-SAN) is enabled.
- Introduce IPPROTO_SMC for selecting SMC when socket is created.
- Allow UDP GSO transmit from devices with no checksum offload.
- openvswitch: add packet sampling via psample, separating the sampled
traffic from "upcall" packets sent to user space for forwarding.
- nf_tables: shrink memory consumption for transaction objects.
Things we sprinkled into general kernel code
--------------------------------------------
- Power Sequencing subsystem (used by Qualcomm Bluetooth driver
for QCA6390).
- Add IRQ information in sysfs for auxiliary bus.
- Introduce guard definition for local_lock.
- Add aligned flavor of __cacheline_group_{begin, end}() markings for
grouping fields in structures.
BPF
---
- Notify user space (via epoll) when a struct_ops object is getting
detached/unregistered.
- Add new kfuncs for a generic, open-coded bits iterator.
- Enable BPF programs to declare arrays of kptr, bpf_rb_root, and
bpf_list_head.
- Support resilient split BTF which cuts down on duplication and makes
BTF as compact as possible WRT BTF from modules.
- Add support for dumping kfunc prototypes from BTF which enables both
detecting as well as dumping compilable prototypes for kfuncs.
- riscv64 BPF JIT improvements in particular to add 12-argument support
for BPF trampolines and to utilize bpf_prog_pack for the latter.
- Add the capability to offload the netfilter flowtable in XDP layer
through kfuncs.
Driver API
----------
- Allow users to configure IRQ tresholds between which automatic IRQ
moderation can choose.
- Expand Power Sourcing (PoE) status with power, class and failure
reason. Support setting power limits.
- Track additional RSS contexts in the core, make sure configuration
changes don't break them.
- Support IPsec crypto offload for IPv6 ESP and IPv4 UDP-encapsulated ESP
data paths.
- Support updating firmware on SFP modules.
Tests and tooling
-----------------
- mptcp: use net/lib.sh to manage netns.
- TCP-AO and TCP-MD5: replace debug prints used by tests with
tracepoints.
- openvswitch: make test self-contained (don't depend on OvS CLI tools).

net: Add struct kernel_ethtool_ts_info
In prevision to add new UAPI for hwtstamp we will be limited to the struct ethtool_ts_info that is currently passed in fixed binary format through the ETHTOOL_GET_TS_INFO ethtool ioctl. It would be good if new kernel code already started operating on an extensible kernel variant of that structure, similar in concept to struct kernel_hwtstamp_config vs struct hwtstamp_config. Since struct ethtool_ts_info is in include/uapi/linux/ethtool.h, here we introduce the kernel-only structure in include/linux/ethtool.h. The manual copy is then made in the function called by ETHTOOL_GET_TS_INFO.

ice: Add support for devlink local_forwarding param
Add support for driver-specific devlink local_forwarding param.
Supported values are "enabled", "disabled" and "prioritized".
Default configuration is set to "enabled".
Add documentation in networking/devlink/ice.rst.
In previous generations of Intel NICs the transmit scheduler was only
limited by PCIe bandwidth when scheduling/assigning hairpin-bandwidth
between VFs. Changes to E810 HW design introduced scheduler limitation,
so that available hairpin-bandwidth is bound to external port speed.
In order to address this limitation and enable NFV services such as
"service chaining" a knob to adjust the scheduler config was created.
Driver can send a configuration message to the FW over admin queue and
internal FW logic will reconfigure HW to prioritize and add more BW to
VF to VF traffic. An end result, for example, 10G port will no longer
limit hairpin-bandwidth to 10G and much higher speeds can be achieved.
Devlink local_forwarding param set to "prioritized" enables higher
hairpin-bandwitdh on related PFs. Configuration is applicable only to
8x10G and 4x25G cards.
Changing local_forwarding configuration will trigger CORER reset in
order to take effect.
Example command to change current value:
devlink dev param set pci/0000:b2:00.3 name local_forwarding \
value prioritized \
cmode runtime

ice: Add tracepoint for adding and removing switch rules
Track the number of rules and recipes added to switch. Add a tracepoint to ice_aq_sw_rules(), which shows both rule and recipe count. This information can be helpful when designing a set of rules to program to the hardware, as it shows where the practical limit is. Actual limits are known (64 recipes, 32k rules), but it's hard to translate these values to how many rules the *user* can actually create, because of extra metadata being implicitly added, and recipe/rule chaining. Chaining combines several recipes/rules to create a larger recipe/rule, so one large rule added by the user might actually consume multiple rules from hardware perspective. Rule counter is simply incremented/decremented in ice_aq_sw_rules(), since all rules are added or removed via it. Counting recipes is harder, as recipes can't be removed (only overwritten). Recipes added via ice_aq_add_recipe() could end up being unused, when there is an error in later stages of rule creation. Instead, track the allocation and freeing of recipes, which should reflect the actual usage of recipes (if something fails after recipe(s) were created, caller should free them). Also, a number of recipes are loaded from NVM by default - initialize the recipe counter with the number of these recipes on switch initialization. Example configuration: cd /sys/kernel/tracing echo function > current_tracer echo ice_aq_sw_rules > set_ftrace_filter echo ice_aq_sw_rules > set_event echo 1 > tracing_on cat trace Example output: tc-4097 [069] ...1. 787.595536: ice_aq_sw_rules <-ice_rem_adv_rule tc-4097 [069] ..... 787.595705: ice_aq_sw_rules: rules=9 recipes=15 tc-4098 [057] ...1. 787.652033: ice_aq_sw_rules <-ice_add_adv_rule tc-4098 [057] ..... 787.652201: ice_aq_sw_rules: rules=10 recipes=16 Reviewed-by: Michal Swiatkowski <michal.swiatkowski@linux.intel.com> Reviewed-by: Przemek Kitszel <przemyslaw.kitszel@intel.com> Signed-off-by: Marcin Szycik <marcin.szycik@linux.intel.com> Reviewed-by: Simon Horman <horms@kernel.org> Tested-by: Sujai Buvaneswaran <sujai.buvaneswaran@intel.com> Signed-off-by: Tony Nguyen <anthony.l.nguyen@intel.com> |

ice: Optimize switch recipe creation
Currently when creating switch recipes, switch ID is always added as the first word in every recipe. There are only 5 words in a recipe, so one word is always wasted. This is also true for the last recipe, which stores result indexes (in case of chain recipes). Therefore the maximum usable length of a chain recipe is 4 * 4 = 16 words. 4 words in a recipe, 4 recipes that can be chained (using a 5th one for result indexes). Current max size chained recipe: 0: smmmm 1: smmmm 2: smmmm 3: smmmm 4: srrrr Where: s - switch ID m - regular match (e.g. ipv4 src addr, udp dst port, etc.) r - result index Switch ID does not actually need to be present in every recipe, only in one of them (in case of chained recipe). This frees up to 8 extra words: 3 from recipes in the middle (because first recipe still needs to have switch ID), and 5 from one extra recipe (because now the last recipe also does not have switch ID, so it can chain 1 more recipe). Max size chained recipe after changes: 0: smmmm 1: Mmmmm 2: Mmmmm 3: Mmmmm 4: MMMMM 5: Rrrrr Extra usable words available after this change are highlighted with capital letters. Changing how switch ID is added is not straightforward, because it's not a regular lookup. Its FV index and mask can't be determined based on protocol + offset pair read from package and instead need to be added manually. Additionally, change how result indexes are added. Currently they are always inserted in a new recipe at the end. Example for 13 words, (with above optimization, switch ID being one of the words): 0: smmmm 1: mmmmm 2: mmmxx 3: rrrxx Where: x - unused word In this and some other cases, the result indexes can be moved just after last matches because there are unused words, saving one recipe. Example for 13 words after both optimizations: 0: smmmm 1: mmmmm 2: mmmrr Note how one less result index is needed in this case, because the last recipe does not need to "link" to itself. There are cases when adding an additional recipe for result indexes cannot be avoided. In that cases result indexes are all put in the last recipe. Example for 14 words after both optimizations: 0: smmmm 1: mmmmm 2: mmmmx 3: rrrxx With these two changes, recipes/rules are more space efficient, allowing more to be created in total.

ice: remove unused recipe bookkeeping data
Remove root_buf from recipe struct. Its only usage was in ice_find_recp(), where if recipe had an inverse action, it was skipped, but actually the driver never adds inverse actions, so effectively it was pointless.

ice: use proper macro for testing bit
Do not use _test_bit() macro for testing bit. The proper macro for this
is one without underline.
_test_bit() is what test_bit() was prior to const-optimization. It
directly calls arch_test_bit(), i.e. the arch-specific implementation
(or the generic one). It's strictly _internal_ and shouldn't be used
anywhere outside the actual test_bit() macro.
test_bit() is a wrapper which checks whether the bitmap and the bit
number are compile-time constants and if so, it calls the optimized
function which evaluates this call to a compile-time constant as well.
If either of them is not a compile-time constant, it just calls _test_bit().
test_bit() is the actual function to use anywhere in the kernel.
IOW, calling _test_bit() avoids potential compile-time optimizations.
The sensors is not a compile-time constant, thus most probably there
are no object code changes before and after the patch.
But anyway, we shouldn't call internal wrappers instead of
the actual API.

ice: Reject pin requests with unsupported flags
The driver receives requests for configuring pins via the .enable
callback of the PTP clock object. These requests come into the driver
with flags which modify the requested behavior from userspace. Current
implementation in ice does not reject flags that it doesn't support.
This causes the driver to incorrectly apply requests with such flags as
PTP_PEROUT_DUTY_CYCLE, or any future flags added by the kernel which it
is not yet aware of.
Fix this by properly validating flags in both ice_ptp_cfg_perout and
ice_ptp_cfg_extts. Ensure that we check by bit-wise negating supported
flags rather than just checking and rejecting known un-supported flags.
This is preferable, as it ensures better compatibility with future
kernels.

ice: Don't process extts if PTP is disabled
The ice_ptp_extts_event() function can race with ice_ptp_release() and
result in a NULL pointer dereference which leads to a kernel panic.
Panic occurs because the ice_ptp_extts_event() function calls
ptp_clock_event() with a NULL pointer. The ice driver has already
released the PTP clock by the time the interrupt for the next external
timestamp event occurs.
To fix this, modify the ice_ptp_extts_event() function to check the
PTP state and bail early if PTP is not ready.

ice: Fix improper extts handling
Extts events are disabled and enabled by the application ts2phc.
However, in case where the driver is removed when the application is
running, a specific extts event remains enabled and can cause a kernel
crash.
As a side effect, when the driver is reloaded and application is started
again, remaining extts event for the channel from a previous run will
keep firing and the message "extts on unexpected channel" might be
printed to the user.
To avoid that, extts events shall be disabled when PTP is released.

ice: do not init struct ice_adapter more times than needed
Allocate and initialize struct ice_adapter object only once per physical card instead of once per port. This is not a big deal by now, but we want to extend this struct more and more in the near future. Our plans include PTP stuff and a devlink instance representing whole-device/physical card. Transactions requiring to be sleep-able (like those doing user (here ice) memory allocation) must be performed with an additional (on top of xarray) mutex. Adding it here removes need to xa_lock() manually. Since this commit is a reimplementation of ice_adapter_get(), a rather new scoped_guard() wrapper for locking is used to simplify the logic. It's worth to mention that xa_insert() use gives us both slot reservation and checks if it is already filled, what simplifies code a tiny bit.

ice: Distinguish driver reset and removal for AQ shutdown
Admin queue command for shutdown AQ contains a flag to indicate driver unload. However, the flag is always set in the driver, even for resets. It can cause the firmware to consider driver as unloaded once the PF reset is triggered on all ports of device, which could lead to unexpected results. Add an additional function parameter to functions that shutdown AQ, indicating whether the driver is actually unloading.

ice: Fix VSI list rule with ICE_SW_LKUP_LAST type
Adding/updating VSI list rule, as well as allocating/freeing VSI list
resource are called several times with type ICE_SW_LKUP_LAST, which fails
because ice_update_vsi_list_rule() and ice_aq_alloc_free_vsi_list()

This fixes at least one issue in switchdev mode, where the same rule with
different action cannot be added, e.g.:
tc filter add dev $PF1 ingress protocol arp prio 0 flower skip_sw \

ice: avoid IRQ collision to fix init failure on ACPI S3 resume
A bug in https://bugzilla.kernel.org/show_bug.cgi?id=218906 describes
that irdma would break and report hardware initialization failed after
suspend/resume with Intel E810 NIC (tested on 6.9.0-rc5).
The problem is caused due to the collision between the irq numbers
requested in irdma and the irq numbers requested in other drivers
after suspend/resume.
The irq numbers used by irdma are derived from ice's ice_pf->msix_entries
which stores mappings between MSI-X index and Linux interrupt number.
It's supposed to be cleaned up when suspend and rebuilt in resume but
it's not, causing irdma using the old irq numbers stored in the old
ice_pf->msix_entries to request_irq() when resume. And eventually
collide with other drivers.
This patch fixes this problem. On suspend, we call ice_deinit_rdma() to
clean up the ice_pf->msix_entries (and free the MSI-X vectors used by
irdma if we've dynamically allocated them). On resume, we call
ice_init_rdma() to rebuild the ice_pf->msix_entries (and allocate the
MSI-X vectors if we would like to dynamically allocate them).

auxbus: make to_auxiliary_drv accept and return a constant pointer

As the return type previously was not constant, also fix up all callers that were assuming that the pointer was not going to be a constant one in order to not break the build.

ice: use irq_update_affinity_hint()
irq_set_affinity_hint() is deprecated. Use irq_update_affinity_hint()
instead. This removes the side-effect of actually applying the affinity.
The driver does not really need to worry about spreading its IRQs across
CPUs. The core code already takes care of that.
On the contrary, when the driver applies affinities by itself, it breaks
the users' expectations:
1. The user configures irqbalance with IRQBALANCE_BANNED_CPULIST in
order to prevent IRQs from being moved to certain CPUs that run a
real-time workload.
2. ice reconfigures VSIs at runtime due to a MIB change
(ice_dcb_process_lldp_set_mib_change). Reopening a VSI resets the
affinity in ice_vsi_req_irq_msix().
3. ice has no idea about irqbalance's config, so it may move an IRQ to
a banned CPU. The real-time workload suffers unacceptable latency.
I am not sure if updating the affinity hints is at all useful, because
irqbalance ignores them since 2016 ([1]), but at least it's harmless.
This ice change is similar to i40e commit

ice: add and use roundup_u64 instead of open coding equivalent
In ice_ptp_cfg_clkout(), the ice driver needs to calculate the nearest next second of a current time value specified in nanoseconds. It implements this using div64_u64, because the time value is a u64. It could use div_u64 since NSEC_PER_SEC is smaller than 32-bits. Ideally this would be implemented directly with roundup(), but that can't work on all platforms due to a division which requires using the specific macros and functions due to platform restrictions, and to ensure that the most appropriate and fast instructions are used. The kernel doesn't currently provide any 64-bit equivalents for doing roundup. Attempting to use roundup() on a 32-bit platform will result in a link failure due to not having a direct 64-bit division. The closest equivalent for this is DIV64_U64_ROUND_UP, which does a division always rounding up. However, this only computes the division, and forces use of the div64_u64 in cases where the divisor is a 32bit value and could make use of div_u64. Introduce DIV_U64_ROUND_UP based on div_u64, and then use it to implement roundup_u64 which takes a u64 input value and a u32 rounding value. The name roundup_u64 matches the naming scheme of div_u64, and future patches could implement roundup64_u64 if they need to round by a multiple that is greater than 32-bits. Replace the logic in ice_ptp.c which does this equivalent with the newly added roundup_u64.

ice_pf_dcb_recfg() re-maps queues to vectors with

Also, move the code around, so XDP queues are mapped independently only
