idpf: protect shutdown from reset
Before the referenced commit, the shutdown just called idpf_remove(),
this way IDPF_REMOVE_IN_PROG was protecting us from the serv_task
rescheduling reset. Without this flag set the shutdown process is
vulnerable to HW reset or any other triggering conditions (such as
default mailbox being destroyed).
When one of conditions checked in idpf_service_task becomes true,
vc_event_task can be rescheduled during shutdown, this leads to accessing
freed memory e.g. idpf_req_rel_vector_indexes() trying to read
vport->q_vector_idxs. This in turn causes the system to become defunct
during e.g. systemctl kexec.
Considering using IDPF_REMOVE_IN_PROG would lead to more heavy shutdown
process, instead just cancel the serv_task before cancelling
adapter->serv_task before cancelling adapter->vc_event_task to ensure that
reset will not be scheduled while we are doing a shutdown.

idpf: fix potential memory leak on kcalloc() failure
In case of failing on rss_data->rss_key allocation the function is
freeing vport without freeing earlier allocated q_vector_idxs. Fix it.
Move from freeing in error branch to goto scheme.

idpf: fix offloads support for encapsulated packets
Split offloads into csum, tso and other offloads so that tunneled
packets do not by default have all the offloads enabled.
Stateless offloads for encapsulated packets are not yet supported in
firmware/software but in the driver we were setting the features same as
non encapsulated features.
Fixed naming to clarify CSUM bits are being checked for Tx.
Inherit netdev features to VLAN interfaces as well.

ice: fix Get Tx Topology AQ command error on E830
The Get Tx Topology AQ command (opcode 0x0418) has different read flag
requirements depending on the hardware/firmware. For E810, E822, and E823
firmware the read flag must be set, and for newer hardware (E825 and E830)
it must not be set.
This results in failure to configure Tx topology and the following warning
message during probe:
DDP package does not support Tx scheduling layers switching feature -
please update to the latest DDP package and try again
The current implementation only handles E825-C but not E830. It is
confusing as we first check ice_is_e825c() and then set the flag in the set
case. Finally, we check ice_is_e825c() again and set the flag for all other
hardware in both the set and get case.
Instead, notice that we always need the read flag for set, but only need
the read flag for get on E810, E822, and E823 firmware. Fix the logic to
check the MAC type and set the read flag in get only on the older devices
which require it.

igc: add lock preventing multiple simultaneous PTM transactions
Add a mutex around the PTM transaction to prevent multiple transactors
Multiple processes try to initiate a PTM transaction, one or all may
fail. This can be reproduced by running two instances of the
following:
$ sudo phc2sys -O 0 -i tsn0 -m
PHC2SYS exits with:
"ioctl PTP_OFFSET_PRECISE: Connection timed out" when the PTM transaction
fails
Note: Normally two instance of PHC2SYS will not run, but one process
should not break another.

igc: fix PTM cycle trigger logic
Writing to clear the PTM status 'valid' bit while the PTM cycle is
triggered results in unreliable PTM operation. To fix this, clear the
PTM 'trigger' and status after each PTM transaction.
The issue can be reproduced with the following:
$ sudo phc2sys -R 1000 -O 0 -i tsn0 -m
Note: 1000 Hz (-R 1000) is unrealistically large, but provides a way to
quickly reproduce the issue.
PHC2SYS exits with:
"ioctl PTP_OFFSET_PRECISE: Connection timed out" when the PTM transaction
fails
This patch also fixes a hang in igc_probe() when loading the igc
driver in the kdump kernel on systems supporting PTM.
The igc driver running in the base kernel enables PTM trigger in
igc_probe(). Therefore the driver is always in PTM trigger mode,
except in brief periods when manually triggering a PTM cycle.
When a crash occurs, the NIC is reset while PTM trigger is enabled.
Due to a hardware problem, the NIC is subsequently in a bad busmaster
state and doesn't handle register reads/writes. When running
igc_probe() in the kdump kernel, the first register access to a NIC
register hangs driver probing and ultimately breaks kdump.
With this patch, igc has PTM trigger disabled most of the time,
and the trigger is only enabled for very brief (10 - 100 us) periods
when manually triggering a PTM cycle. Chances that a crash occurs
during a PTM trigger are not 0, but extremely reduced.

idpf: fix adapter NULL pointer dereference on reboot
With SRIOV enabled, idpf ends up calling into idpf_remove() twice.
First via idpf_shutdown() and then again when idpf_remove() calls into
sriov_disable(), because the VF devices use the idpf driver, hence the
same remove routine. When that happens, it is possible for the adapter
to be NULL from the first call to idpf_remove(), leading to a NULL
pointer dereference.
echo 1 > /sys/class/net/<netif>/device/sriov_numvfs
reboot
BUG: kernel NULL pointer dereference, address: 0000000000000020

Replace the direct idpf_remove() call in idpf_shutdown() with
idpf_vc_core_deinit() and idpf_deinit_dflt_mbx(), which perform
the bulk of the cleanup, such as stopping the init task, freeing IRQs,
destroying the vports and freeing the mailbox. This avoids the calls to
sriov_disable() in addition to a small netdev cleanup, and destroying
workqueues, which don't seem to be required on shutdown.

e1000e: change k1 configuration on MTP and later platforms
Starting from Meteor Lake, the Kumeran interface between the integrated
MAC and the I219 PHY works at a different frequency. This causes sporadic
MDI errors when accessing the PHY, and in rare circumstances could lead
to packet corruption.
To overcome this, introduce minor changes to the Kumeran idle
state (K1) parameters during device initialization. Hardware reset
reverts this configuration, therefore it needs to be applied in a few
places.

igc: Fix TX drops in XDP ZC
Fixes TX frame drops in AF_XDP zero copy mode when budget < 4.
xsk_tx_peek_desc() consumed TX frame and it was ignored because of
low budget. Not even AF_XDP completion was done for dropped frames.
It can be reproduced on i226 by sending 100000x 60 B frames with
launch time set to minimal IPG (672 ns between starts of frames)
on 1Gbit/s. Always 1026 frames are not sent and are missing a
completion.

Networking changes for 6.15.
Core & protocols
----------------
- Continue Netlink conversions to per-namespace RTNL lock
(IPv4 routing, routing rules, routing next hops, ARP ioctls).
- Continue extending the use of netdev instance locks. As a driver
opt-in protect queue operations and (in due course) ethtool
operations with the instance lock and not RTNL lock.
- Support collecting TCP timestamps (data submitted, sent, acked)
in BPF, allowing for transparent (to the application) and lower
overhead tracking of TCP RPC performance.
- Tweak existing networking Rx zero-copy infra to support zero-copy
Rx via io_uring.
- Optimize MPTCP performance in single subflow mode by 29%.
- Enable GRO on packets which went thru XDP CPU redirect (were queued
for processing on a different CPU). Improving TCP stream performance
up to 2x.
- Improve performance of contended connect() by 200% by searching
for an available 4-tuple under RCU rather than a spin lock.
Bring an additional 229% improvement by tweaking hash distribution.
- Avoid unconditionally touching sk_tsflags on RX, improving
performance under UDP flood by as much as 10%.
- Avoid skb_clone() dance in ping_rcv() to improve performance under
ping flood.
- Avoid FIB lookup in netfilter if socket is available, 20% perf win.
- Rework network device creation (in-kernel) API to more clearly
identify network namespaces and their roles.
There are up to 4 namespace roles but we used to have just 2 netns
pointer arguments, interpreted differently based on context.
- Use sysfs_break_active_protection() instead of trylock to avoid
deadlocks between unregistering objects and sysfs access.
- Add a new sysctl and sockopt for capping max retransmit timeout
in TCP.
- Support masking port and DSCP in routing rule matches.
- Support dumping IPv4 multicast addresses with RTM_GETMULTICAST.
- Support specifying at what time packet should be sent on AF_XDP
sockets.
- Expose TCP ULP diagnostic info (for TLS and MPTCP) to non-admin users.
- Add Netlink YAML spec for WiFi (nl80211) and conntrack.
- Introduce EXPORT_IPV6_MOD() and EXPORT_IPV6_MOD_GPL() for symbols
which only need to be exported when IPv6 support is built as a module.
- Age FDB entries based on Rx not Tx traffic in VxLAN, similar
to normal bridging.
- Allow users to specify source port range for GENEVE tunnels.
- netconsole: allow attaching kernel release, CPU ID and task name
to messages as metadata

A treewide hrtimer timer cleanup
hrtimers are initialized with hrtimer_init() and a subsequent store to the callback pointer. This turned out to be suboptimal for the upcoming Rust integration and is obviously a silly implementation to begin with. This cleanup replaces the hrtimer_init(T); T->function = cb; sequence with hrtimer_setup(T, cb); The conversion was done with Coccinelle and a few manual fixups. Once the conversion has completely landed in mainline, hrtimer_init() will be removed and the hrtimer::function becomes a private member. -----BEGIN PGP SIGNATURE----- iQJHBAABCgAxFiEEQp8+kY+LLUocC4bMphj1TA10mKEFAmff5jQTHHRnbHhAbGlu dXRyb25peC5kZQAKCRCmGPVMDXSYoVvRD/wKtuwmiA66NJFgXC0qVq82A6fO3bY8 GBdbfysDJIbqGu5PTcULTbJ8qkqv3jeLUv6CcXvS4sZ7y/uJQl2lzf8yrD/0bbwc rLI6sHiPSZmK93kNVN4X5H7kvt7cE/DYC9nnEOgK3BY5FgKc4n9887d4aVBhL8Lv ODwVXvZ+xi351YCj7qRyPU24zt/p4tkkT1o2k4a0HBluqLI0D+V20fke9IERUL8r d1uWKlcn0TqYDesE8HXKIhbst3gx52rMJrXBJDHwFmG6v8Pj1fkTXCVpPo8QcBz8 OTVkpomN9f/Tx4+GZwhZOF86LhLL3OhxD6pT7JhFCXdmSGv+Ez8uyk1YZysM/XpV Juy/1yAcBpDIDkmhMFGdAAn48Nn9Fotty0r4je60zSEp1d/4QMXcFme29qr2JTUE iWnQ/HD6DxUjVHqy7CYvvo26Xegg1C7qgyOVt4PYZwAM1VKF5P3kzYTb4SAdxtop Tpji1sfW9QV08jqMNo6XntD32DSP9S2HqjO9LwBw700jnx2jjJ35fcJs6iodMOUn gckIZLMn3L0OoglPdyA5O7SNTbKE7aFiRKdnT/cJtR3Fa39Qu27CwC5gfiyuie9I Q+LG8GLuYSBHXAR+PBK4GWlzJ7Dn8k3eqmbnLeKpRMsU6ZzcttgA64xhaviN2wN0 iJbvLJeisXr3GA== =bYAX -----END PGP SIGNATURE----- Merge tag 'timers-cleanups-2025-03-23' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip Pull timer cleanups from Thomas Gleixner: "A treewide hrtimer timer cleanup hrtimers are initialized with hrtimer_init() and a subsequent store to the callback pointer.

igb: reject invalid external timestamp requests for 82580-based HW
The igb_ptp_feature_enable_82580 function correctly checks that unknown
flags are not passed to the function. However, it does not actually check
PTP_RISING_EDGE or PTP_FALLING_EDGE when configuring the external timestamp
function.
The data sheet for the 82580 product says:
Upon a change in the input level of one of the SDP pins that was
configured to detect Time stamp events using the TSSDP register, a time
stamp of the system time is captured into one of the two auxiliary time
stamp registers (AUXSTMPL/H0 or AUXSTMPL/H1).
For example to define timestamping of events in the AUXSTMPL0 and
AUXSTMPH0 registers, Software should:
1. Set the TSSDP.AUX0_SDP_SEL field to select the SDP pin that detects
the level change and set the TSSDP.AUX0_TS_SDP_EN bit to 1.
2. Set the TSAUXC.EN_TS0 bit to 1 to enable timestamping
The same paragraph is in the i350 and i354 data sheets.
The wording implies that the time stamps are captured at any level change.
There does not appear to be any way to only timestamp one edge of the
signal.
Reject requests which do not set both PTP_RISING_EDGE and PTP_FALLING_EDGE
when operating under PTP_STRICT_FLAGS mode via PTP_EXTTS_REQUEST2.

ice: fix reservation of resources for RDMA when disabled
If the CONFIG_INFINIBAND_IRDMA symbol is not enabled as a module or a
built-in, then don't let the driver reserve resources for RDMA. The result
of this change is a large savings in resources for older kernels, and a
cleaner driver configuration for the IRDMA=n case for old and new kernels.
Implement this by avoiding enabling the RDMA capability when scanning
hardware capabilities.
Note: Loading the out-of-tree irdma driver in connection to the in-kernel
ice driver, is not supported, and should not be attempted, especially when
disabling IRDMA in the kernel config.

ice: ensure periodic output start time is in the future
On E800 series hardware, if the start time for a periodic output signal is programmed into GLTSYN_TGT_H and GLTSYN_TGT_L registers, the hardware logic locks up and the periodic output signal never starts. Any future attempt to reprogram the clock function is futile as the hardware will not reset until a power on. The ice_ptp_cfg_perout function has logic to prevent this, as it checks if the requested start time is in the past. If so, a new start time is calculated by rounding up. Since commit |

ixgbe: add support for thermal sensor event reception
E610 NICs unlike the previous devices utilising ixgbe driver are notified in the case of overheating by the FW ACI event. In event of overheat when threshold is exceeded, FW suspends all traffic and sends overtemp event to the driver. Then driver logs appropriate message and disables the adapter instance. The card remains in that state until the platform is rebooted. This approach is a solution to the fact current version of the E610 FW doesn't support reading thermal sensor data by the SW. So give to user at least any info that overtemp event has occurred, without interface disappearing from the OS without any note.

ice: Add E830 checksum offload support
E830 supports raw receive and generic transmit checksum offloads. Raw receive checksum support is provided by hardware calculating the checksum over the whole packet, regardless of type. The calculated checksum is provided to driver in the Rx flex descriptor. Then the driver assigns the checksum to skb->csum and sets skb->ip_summed to CHECKSUM_COMPLETE. Generic transmit checksum support is provided by hardware calculating the checksum given two offsets: the start offset to begin checksum calculation, and the offset to insert the calculated checksum in the packet. Support is advertised to the stack using NETIF_F_HW_CSUM feature. E830 has the following limitations when both generic transmit checksum offload and TCP Segmentation Offload (TSO) are enabled: 1. Inner packet header modification is not supported. This restriction includes the inability to alter TCP flags, such as the push flag. As a result, this limitation can impact the receiver's ability to coalesce packets, potentially degrading network throughput. 2. The Maximum Segment Size (MSS) is limited to 1023 bytes, which prevents support of Maximum Transmission Unit (MTU) greater than 1063 bytes. Therefore NETIF_F_HW_CSUM and NETIF_F_ALL_TSO features are mutually exclusive. NETIF_F_HW_CSUM hardware feature support is indicated but is not enabled by default. Instead, IP checksums and NETIF_F_ALL_TSO are the defaults. Enforcement of mutual exclusivity of NETIF_F_HW_CSUM and NETIF_F_ALL_TSO is done in ice_set_features(). Mutual exclusivity of IP checksums and NETIF_F_HW_CSUM is handled by netdev_fix_features(). When NETIF_F_HW_CSUM is requested the provided skb->csum_start and skb->csum_offset are passed to hardware in the Tx context descriptor generic checksum (GCS) parameters. Hardware calculates the 1's complement from skb->csum_start to the end of the packet, and inserts the result in the packet at skb->csum_offset.

net: move misc netdev_lock flavors to a separate header
Move the more esoteric helpers for netdev instance lock to a dedicated header. This avoids growing netdevice.h to infinity and makes rebuilding the kernel much faster (after touching the header with the helpers). The main netdev_lock() / netdev_unlock() functions are used in static inlines in netdevice.h and will probably be used most commonly, so keep them in netdevice.h.

net: hold netdev instance lock during ndo_open/ndo_stop
For the drivers that use shaper API, switch to the mode where
core stack holds the netdev lock. This affects two drivers:
* iavf - already grabs netdev lock in ndo_open/ndo_stop, so mostly
remove these
* netdevsim - switch to _locked APIs to avoid deadlock
iavf_close diff is a bit confusing, the existing call looks like this:
iavf_close() {
netdev_lock()
..
netdev_unlock()
wait_event_timeout(down_waitqueue)
}
I change it to the following:
netdev_lock()
iavf_close() {
..
netdev_unlock()
wait_event_timeout(down_waitqueue)
netdev_lock() // reusing this lock call
}
netdev_unlock()
Since I'm reusing existing netdev_lock call, so it looks like I only
add netdev_unlock.

ice: Fix switchdev slow-path in LAG
Ever since removing switchdev control VSI and using PF for port
representor Tx/Rx, switchdev slow-path has been working improperly after
failover in SR-IOV LAG. LAG assumes that the first uplink to be added to
the aggregate will own VFs and have switchdev configured. After
failing-over to the other uplink, representors are still configured to
Tx through the uplink they are set up on, which fails because that
uplink is now down.
On failover, update all PRs on primary uplink to use the currently
active uplink for Tx. Call netif_keep_dst(), as the secondary uplink
might not be in switchdev mode. Also make sure to call
ice_eswitch_set_target_vsi() if uplink is in LAG.
On the Rx path, representors are already working properly, because
default Tx from VFs is set to PF owning the eswitch. After failover the
same PF is receiving traffic from VFs, even though link is down.

ice: fix memory leak in aRFS after reset
Fix aRFS (accelerated Receive Flow Steering) structures memory leak by
adding a checker to verify if aRFS memory is already allocated while
configuring VSI. aRFS objects are allocated in two cases:
- as part of VSI initialization (at probe), and
- as part of reset handling
However, VSI reconfiguration executed during reset involves memory
allocation one more time, without prior releasing already allocated
resources. This led to the memory leak with the following signature:

ice: do not configure destination override for switchdev
After switchdev is enabled and disabled later, LLDP packets sending stops,
despite working perfectly fine before and during switchdev state.
To reproduce (creating/destroying VF is what triggers the reconfiguration):
devlink dev eswitch set pci/<address> mode switchdev
echo '2' > /sys/class/net/<ifname>/device/sriov_numvfs
echo '0' > /sys/class/net/<ifname>/device/sriov_numvfs
This happens because LLDP relies on the destination override functionality.
It needs to 1) set a flag in the descriptor, 2) set the VSI permission to
make it valid. The permissions are set when the PF VSI is first configured,
but switchdev then enables it for the uplink VSI (which is always the PF)
once more when configured and disables when deconfigured, which leads to
software-generated LLDP packets being blocked.
Do not modify the destination override permissions when configuring
switchdev, as the enabled state is the default configuration that is never
modified.

idpf: fix checksums set in idpf_rx_rsc()
idpf_rx_rsc() uses skb_transport_offset(skb) while the transport header
is not set yet.
This triggers the following warning for CONFIG_DEBUG_NET=y builds.
