2024-07-11i40e: fix: remove needless retries of NVM updateAleksandr Loktionov
Remove wrong EIO to EGAIN conversion and pass all errors as is. After commit 230f3d53a547 ("i40e: remove i40e_status"), which should only replace F/W specific error codes with Linux kernel generic, all EIO errors suddenly started to be converted into EAGAIN which leads nvmupdate to retry until it timeouts and sometimes fails after more than 20 minutes in the middle of NVM update, so NVM becomes corrupted. The bug affects users only at the time when they try to update NVM, and only F/W versions that generate errors while nvmupdate. For example, X710DA2 with 0x8000ECB7 F/W is affected, but there are probably more... Command for reproduction is just NVM update: ./nvmupdate64 In the log instead of: i40e_nvmupd_exec_aq err I40E_ERR_ADMIN_QUEUE_ERROR aq_err I40E_AQ_RC_ENOMEM) appears: i40e_nvmupd_exec_aq err -EIO aq_err I40E_AQ_RC_ENOMEM i40e: eeprom check failed (-5), Tx/Rx traffic disabled The problematic code did silently convert EIO into EAGAIN which forced nvmupdate to ignore EAGAIN error and retry the same operation until timeout. That's why NVM update takes 20+ minutes to finish with the fail in the end.

2024-07-11net: ks8851: Fix potential TX stall after interface reopenRonald Wahl
The amount of TX space in the hardware buffer is tracked in the tx_space variable. The initial value is currently only set during driver probing. After closing the interface and reopening it the tx_space variable has the last value it had before close. If it is smaller than the size of the first send packet after reopeing the interface the queue will be stopped. The queue is woken up after receiving a TX interrupt but this will never happen since we did not send anything. This commit moves the initialization of the tx_space variable to the ks8851_net_open function right before starting the TX queue. Also query the value from the hardware instead of using a hard coded value. Only the SPI chip variant is affected by this issue because only this driver variant actually depends on the tx_space variable in the xmit function.

2024-07-10e1000e: fix force smbus during suspend flowVitaly Lifshits
Commit 861e8086029e ("e1000e: move force SMBUS from enable ulp function to avoid PHY loss issue") resolved a PHY access loss during suspend on Meteor Lake consumer platforms, but it affected corporate systems incorrectly. A better fix, working for both consumer and corporate systems, was proposed in commit bfd546a552e1 ("e1000e: move force SMBUS near the end of enable_ulp function"). However, it introduced a regression on older devices, such as [8086:15B8], [8086:15F9], [8086:15BE]. This patch aims to fix the secondary regression, by limiting the scope of the changes to Meteor Lake platforms only.

2024-07-09i40e: Fix XDP program unloading while removing the driverMichal Kubiak
The commit 6533e558c650 ("i40e: Fix reset path while removing the driver") introduced a new PF state "__I40E_IN_REMOVE" to block modifying the XDP program while the driver is being removed. Unfortunately, such a change is useful only if the ".ndo_bpf()" callback was called out of the rmmod context because unloading the existing XDP program is also a part of driver removing procedure. In other words, from the rmmod context the driver is expected to unload the XDP program without reporting any errors. Otherwise, the kernel warning with callstack is printed out to dmesg. Example failing scenario: 1. Load the i40e driver. 2. Load the XDP program. 3. Unload the i40e driver (using "rmmod" command).

2024-07-09bnxt: fix crashes when reducing ring count with active RSS contextsJakub Kicinski
bnxt doesn't check if a ring is used by RSS contexts when reducing ring count. Core performs a similar check for the drivers for the main context, but core doesn't know about additional contexts, so it can't validate them. bnxt_fill_hw_rss_tbl_p5() uses ring id to index bp->rx_ring[], which without the check may end up being out of bounds.

2024-07-04bnxt_en: Fix the resource check condition for RSS contextsPavan Chebbi
While creating a new RSS context, bnxt_rfs_capable() currently makes a strict check to see if the required VNICs are already available. If the current VNICs are not what is required, either too many or not enough, it will call the firmware to reserve the exact number required. There is a bug in the firmware when the driver tries to relinquish some reserved VNICs and RSS contexts. It will cause the default VNIC to lose its RSS configuration and cause receive packets to be placed incorrectly. Workaround this problem by skipping the resource reduction. The driver will not reduce the VNIC and RSS context reservations when a context is deleted. The resources will be available for use when new contexts are created later. Potentially, this workaround can cause us to run out of VNIC and RSS contexts if there are a lot of VF functions creating and deleting RSS contexts. In the future, we will conditionally disable this workaround when the firmware fix is available.

2024-07-03ice: use proper macro for testing bitPetr Oros
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.

2024-07-03ice: Reject pin requests with unsupported flagsJacob Keller
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.

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.

Some of the callers even have a pointer to the mvmvif of the bss vif, so we don't even need to call this function, and can simply get the vif from mvmvif.

Commit 205c50306acf ("wifi: wilc1000: fix RCU usage in connect path") made sure that the IEs data was manipulated under the relevant RCU section. Unfortunately, while doing so, the commit brought a faulty implicit cast from int to u8 on the ies_len variable, making the parsing fail to be performed correctly if the IEs block is larger than 255 bytes. This failure can be observed with Access Points appending a lot of IEs TLVs in their beacon frames (reproduced with a Pixel phone acting as an Access Point, which brough 273 bytes of IE data in my testing environment).

2024-07-01e1000e: Fix S0ix residency on corporate systemsDima Ruinskiy
On vPro systems, the configuration of the I219-LM to achieve power gating and S0ix residency is split between the driver and the CSME FW. It was discovered that in some scenarios, where the network cable is connected and then disconnected, S0ix residency is not always reached. This was root-caused to a subset of I219-LM register writes that are not performed by the CSME FW. Therefore, the driver should perform these register writes on corporate setups, regardless of the CSME FW state. This was discovered on Meteor Lake systems; however it is likely to appear on other platforms as well.

2024-06-28bnx2x: Fix multiple UBSAN array-index-out-of-boundsGhadi Elie Rahme
Fix UBSAN warnings that occur when using a system with 32 physical cpu cores or more, or when the user defines a number of Ethernet queues greater than or equal to FP_SB_MAX_E1x using the num_queues module parameter. Currently there is a read/write out of bounds that occurs on the array "struct stats_query_entry query" present inside the "bnx2x_fw_stats_req" struct in "drivers/net/ethernet/broadcom/bnx2x/bnx2x.h". Looking at the definition of the "struct stats_query_entry query" array: struct stats_query_entry query[FP_SB_MAX_E1x+ BNX2X_FIRST_QUEUE_QUERY_IDX]; FP_SB_MAX_E1x is defined as the maximum number of fast path interrupts and has a value of 16, while BNX2X_FIRST_QUEUE_QUERY_IDX has a value of 3 meaning the array has a total size of 19. Since accesses to "struct stats_query_entry query" are offset-ted by BNX2X_FIRST_QUEUE_QUERY_IDX, that means that the total number of Ethernet queues should not exceed FP_SB_MAX_E1x (16). However one of these queues is reserved for FCOE and thus the number of Ethernet queues should be set to [FP_SB_MAX_E1x -1] (15) if FCOE is enabled or [FP_SB_MAX_E1x] (16) if it is not. This is also described in a comment in the source code in drivers/net/ethernet/broadcom/bnx2x/bnx2x.h just above the Macro definition of FP_SB_MAX_E1x. Below is the part of this explanation that it important for this patch /* * The total number of L2 queues, MSIX vectors and HW contexts (CIDs) is * control by the number of fast-path status blocks supported by the * device (HW/FW). Each fast-path status block (FP-SB) aka non-default * status block represents an independent interrupts context that can * serve a regular L2 networking queue. However special L2 queues such * as the FCoE queue do not require a FP-SB and other components like * the CNIC may consume FP-SB reducing the number of possible L2 queues * * If the maximum number of FP-SB available is X then: * a. If CNIC is supported it consumes 1 FP-SB thus the max number of * regular L2 queues is Y=X-1 * b. In MF mode the actual number of L2 queues is Y= (X-1/MF_factor) * c. If the FCoE L2 queue is supported the actual number of L2 queues * is Y+1 * d. The number of irqs (MSIX vectors) is either Y+1 (one extra for * slow-path interrupts) or Y+2 if CNIC is supported (one additional * FP interrupt context for the CNIC). * e. The number of HW context (CID count) is always X or X+1 if FCoE * L2 queue is supported. The cid for the FCoE L2 queue is always X. */ However this driver also supports NICs that use the E2 controller which can handle more queues due to having more FP-SB represented by FP_SB_MAX_E2. Looking at the commits when the E2 support was added, it was originally using the E1x parameters: commit f2e0899f0f27 ("bnx2x: Add 57712 support"). Back then FP_SB_MAX_E2 was set to 16 the same as E1x. However the driver was later updated to take full advantage of the E2 instead of having it be limited to the capabilities of the E1x. But as far as we can tell, the array "stats_query_entry query" was still limited to using the FP-SB available to the E1x cards as part of an oversignt when the driver was updated to take full advantage of the E2, and now with the driver being aware of the greater queue size supported by E2 NICs, it causes the UBSAN warnings seen in the stack traces below. This patch increases the size of the "stats_query_entry query" array by replacing FP_SB_MAX_E1x with FP_SB_MAX_E2 to be large enough to handle both types of NICs.

2024-06-28net/mlx5e: Approximate IPsec per-SA payload data bytes countLeon Romanovsky
ConnectX devices lack ability to count payload data byte size which is needed for SA to return to libreswan for rekeying. As a solution let's approximate that by decreasing headers size from total size counted by flow steering. The calculation doesn't take into account any other headers which can be in the packet (e.g. IP extensions).

2024-06-28net/mlx5e: Present succeeded IPsec SA bytes and packetLeon Romanovsky
IPsec SA statistics presents successfully decrypted and encrypted packet and bytes, and not total handled by this SA. So update the calculation logic to take into account failures.

2024-06-28net/mlx5e: Add mqprio_rl cleanup and free in mlx5e_priv_cleanup()Jianbo Liu
In the cited commit, mqprio_rl cleanup and free are mistakenly removed in mlx5e_priv_cleanup(), and it causes the leakage of host memory and firmware SCHEDULING_ELEMENT objects while changing eswitch mode. So, add them back.
