2024-05-17net: qede: use return from qede_parse_actions()Asbjørn Sloth Tønnesen1-3/+2
[ Upstream commit f26f719a36e56381a1f4230e5364e7ad4d485888 ] When calling qede_parse_actions() then the return code was only used for a non-zero check, and then -EINVAL was returned. qede_parse_actions() can currently fail with: * -EINVAL * -EOPNOTSUPP This patch changes the code to use the actual return code, not just return -EINVAL.

2023-08-17qede: fix firmware halt over suspend and resumeManish Chopra1-0/+10
While performing certain power-off sequences, PCI drivers are called to suspend and resume their underlying devices through PCI PM (power management) interface. However this NIC hardware does not support PCI PM suspend/resume operations so system wide suspend/resume leads to bad MFW (management firmware) state which causes various follow-up errors in driver when communicating with the device/firmware afterwards. To fix this driver implements PCI PM suspend handler to indicate unsupported operation to the PCI subsystem explicitly, thus avoiding system to go into suspended/standby mode. Without this fix device/firmware does not recover unless system is power cycled.

2023-02-26qede: avoid uninitialized entries in coal_entry arrayMichal Schmidt1-14/+7
Even after commit 908d4bb7c54c ("qede: fix interrupt coalescing configuration"), some entries of the coal_entry array may theoretically be used uninitialized: 1. qede_alloc_fp_array() allocates QEDE_MAX_RSS_CNT entries for coal_entry. The initial allocation uses kcalloc, so everything is initialized. 2. The user sets a small number of queues (ethtool -L). coal_entry is reallocated for the actual small number of queues. 3. The user sets a bigger number of queues. coal_entry is reallocated bigger. The added entries are not necessarily initialized. In practice, the reallocations will actually keep using the originally allocated region of memory, but we should not rely on it. The reallocation is unnecessary. coal_entry can always have QEDE_MAX_RSS_CNT entries.

On default driver load device gets configured with unexpected higher interrupt coalescing values instead of default expected values as memory allocated from krealloc() is not supposed to be zeroed out and may contain garbage values.

2023-02-03drivers: net: turn on XDP featuresMarek Majtyka1-0/+3
A summary of the flags being set for various drivers is given below. Note that XDP_F_REDIRECT_TARGET and XDP_F_FRAG_TARGET are features that can be turned off and on at runtime. This means that these flags may be set and unset under RTNL lock protection by the driver. Hence, READ_ONCE must be used by code loading the flag value. Also, these flags are not used for synchronization against the availability of XDP resources on a device. It is merely a hint, and hence the read may race with the actual teardown of XDP resources on the device. This may change in the future, e.g. operations taking a reference on the XDP resources of the driver, and in turn inhibiting turning off this flag. However, for now, it can only be used as a hint to check whether device supports becoming a redirection target. Turn 'hw-offload' feature flag on for: - netronome (nfp) - netdevsim. Turn 'native' and 'zerocopy' features flags on for: - intel (i40e, ice, ixgbe, igc) - mellanox (mlx5). - stmmac - netronome (nfp) Turn 'native' features flags on for: - amazon (ena) - broadcom (bnxt) - freescale (dpaa, dpaa2, enetc) - funeth - intel (igb) - marvell (mvneta, mvpp2, octeontx2) - mellanox (mlx4) - mtk_eth_soc - qlogic (qede) - sfc - socionext (netsec) - ti (cpsw) - tap - tsnep - veth - xen - virtio_net.

2023-01-28qede: execute xdp_do_flush() before napi_complete_done()Magnus Karlsson1-3/+4
Make sure that xdp_do_flush() is always executed before napi_complete_done(). This is important for two reasons. First, a redirect to an XSKMAP assumes that a call to xdp_do_redirect() from napi context X on CPU Y will be followed by a xdp_do_flush() from the same napi context and CPU. This is not guaranteed if the napi_complete_done() is executed before xdp_do_flush(), as it tells the napi logic that it is fine to schedule napi context X on another CPU. Details from a production system triggering this bug using the veth driver can be found following the first link below. The second reason is that the XDP_REDIRECT logic in itself relies on being inside a single NAPI instance through to the xdp_do_flush() call for RCU protection of all in-kernel data structures. Details can be found in the second link below.

2021-12-14net_tstamp: add new flag HWTSTAMP_FLAG_BONDED_PHC_INDEXHangbin Liu1-5/+0
Since commit 94dd016ae538 ("bond: pass get_ts_info and SIOC[SG]HWTSTAMP ioctl to active device") the user could get bond active interface's PHC index directly. But when there is a failover, the bond active interface will change, thus the PHC index is also changed. This may break the user's program if they did not update the PHC timely. This patch adds a new hwtstamp_config flag HWTSTAMP_FLAG_BONDED_PHC_INDEX. When the user wants to get the bond active interface's PHC, they need to add this flag and be aware the PHC index may be changed. With the new flag. All flag checks in current drivers are removed. Only the checking in net_hwtstamp_validate() is kept. Suggested-by: Jakub Kicinski <kuba@kernel.org> Signed-off-by: Hangbin Liu <liuhangbin@gmail.com> Signed-off-by: David S.

2021-12-14bpf: Let bpf_warn_invalid_xdp_action() report more infoPaolo Abeni1-1/+1
In non trivial scenarios, the action id alone is not sufficient to identify the program causing the warning. Before the previous patch, the generated stack-trace pointed out at least the involved device driver. Let's additionally include the program name and id, and the relevant device name. If the user needs additional infos, he can fetch them via a kernel probe, leveraging the arguments added here.

2021-12-04qed*: esl priv flag support through ethtoolManish Chopra1-0/+13
ESL(Enhanced System Lockdown) was designed to lock PCI adapter firmware images and prevent changes to critical non-volatile configuration data so that uncontrolled, malicious or unintentional modification to the adapters are avoided, ensuring it's operational state. Once this feature is enabled, the device is locked, rejecting any modification to non-volatile images. Once unlocked, the protection is off such that firmware and non-volatile configurations may be altered. Driver just reflects the capability and status of this through the ethtool private flag.

Although it is unlikely that stack could transmit a non LSO skb with length > MTU, however in some cases or environment such occurrences actually resulted into firmware asserts due to packet length being greater than the max supported by the device (~9700B).

2021-10-14ethernet: constify references to netdev->dev_addr in driversJakub Kicinski1-1/+1
This big patch sprinkles const on local variables and function arguments which may refer to netdev->dev_addr. Commit 406f42fa0d3c ("net-next: When a bond have a massive amount of VLANs...") introduced a rbtree for faster Ethernet address look up. To maintain netdev->dev_addr in this tree we need to make all the writes to it got through appropriate helpers. Some of the changes here are not strictly required - const is sometimes cast off but pointer is not used for writing. It seems like it's still better to add the const in case the code changes later or relevant -W flags get enabled for the build. No functional changes.

The existing qed/qede/qedr/qedi/qedf code uses chip-specific naming in structures, functions, variables and defines in FW HSI (Hardware Software Interface). The new FW version introduced a generic naming convention in HSI in-which the same code will be used across different versions for simpler maintainability. It also eases in providing support for new features. With this patch every "_e4" or "e4_" prefix or suffix is not needed anymore and it will be removed.

2021-07-27dev_ioctl: split out ndo_eth_ioctlArnd Bergmann1-1/+1
Most users of ndo_do_ioctl are ethernet drivers that implement the MII commands SIOCGMIIPHY/SIOCGMIIREG/SIOCSMIIREG, or hardware timestamping with SIOCSHWTSTAMP/SIOCGHWTSTAMP. Separate these from the few drivers that use ndo_do_ioctl to implement SIOCBOND, SIOCBR and SIOCWANDEV commands. This is a purely cosmetic change intended to help readers find their way through the implementation.

2021-06-24qede: Remove rcu_read_lock() around XDP program invocationToke Høiland-Jørgensen1-6/+0
The qede driver has rcu_read_lock()/rcu_read_unlock() pairs around XDP program invocations. However, the actual lifetime of the objects referred by the XDP program invocation is longer, all the way through to the call to xdp_do_flush(), making the scope of the rcu_read_lock() too small. This turns out to be harmless because it all happens in a single NAPI poll cycle (and thus under local_bh_disable()), but it makes the rcu_read_lock() misleading. Rather than extend the scope of the rcu_read_lock(), just get rid of it entirely. With the addition of RCU annotations to the XDP_REDIRECT map types that take bh execution into account, lockdep even understands this to be safe, so there's really no reason to keep it around.
