When using MSI/INTx interrupt, the shared interrupts are still being handled in the device remove routine, before free IRQs. So isb memory is still read after it is freed. Thus move wx_free_isb_resources() from txgbe_close() to txgbe_remove(). And fix the improper isb free action in txgbe_open() error handling path.

Rename original txgbe_misc_irq_handle() to txgbe_misc_irq_thread_fn() since it is the handle thread to wake up. And add the primary handler to deal the case of MSI/INTx, because there is a schedule NAPI poll. Fixes: aefd0136 ("net: txgbe: use irq_domain for interrupt controller") Signed-off-by:

When using MSI or INTx interrupts, request_irq() for pdev->irq will conflict with request_threaded_irq() for txgbe->misc.irq, to cause system crash. So remove txgbe_request_irq() for MSI/INTx case, and rename txgbe_request_msix_irqs() since it only request for queue irqs. Add wx->misc_irq_domain to determine whether the driver creates an IRQ domain and threaded request the IRQs. Fixes: aefd0136 ("net: txgbe: use irq_domain for interrupt controller") Signed-off-by:

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.

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 f2e0899f ("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.

Commit 272970be ("Bluetooth: hci_qca: Fix driver shutdown on closed serdev") will cause below regression issue: BT can't be enabled after below steps: cold boot -> enable BT -> disable BT -> warm reboot -> BT enable failure if property enable-gpios is not configured within DT|ACPI for QCA6390. The commit is to fix a use-after-free issue within qca_serdev_shutdown() by adding condition to avoid the serdev is flushed or wrote after closed but also introduces this regression issue regarding above steps since the VSC is not sent to reset controller during warm reboot. Fixed by sending the VSC to reset controller within qca_serdev_shutdown() once BT was ever enabled, and the use-after-free issue is also fixed by this change since the serdev is still opened before it is flushed or wrote.

These two interval are not the same thing: BLUETOOTH CORE SPECIFICATION Version 5.3 | Vol 6, Part G Isochronous interval: The time between two consecutive BIS or CIS events (designated ISO_Interval in the Link Layer) SDU interval: The nominal time between two consecutive SDUs that are sent or received by the upper layer. So this instead uses the following formula from the spec to calculate the resulting SDU interface: BLUETOOTH CORE SPECIFICATION Version 5.4 | Vol 6, Part G page 3075: Transport_Latency_C_To_P = CIG_Sync_Delay + (FT_C_To_P) × ISO_Interval + SDU_Interval_C_To_P Transport_Latency_P_To_C = CIG_Sync_Delay + (FT_P_To_C) × ISO_Interval + SDU_Interval_P_To_C Link: https://github.com/bluez/bluez/issues/823 Fixes: 2be22f19 ("Bluetooth: hci_event: Fix parsing of CIS Established Event") Signed-off-by:

Tariq Toukan says: ==================== mlx5 fixes 2024-06-27 This patchset provides fixes from the team to the mlx5 core and EN drivers. The first 3 patches by Daniel replace a buggy cap field with a newly introduced one. Patch 4 by Chris de-couples ingress ACL creation from a specific flow, so it's invoked by other flows if needed. Patch 5 by Jianbo fixes a possible missing cleanup of QoS objects. Patches 6 and 7 by Leon fixes IPsec stats logic to better reflect the traffic.

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). Fixes: 5a6cddb8 ("net/mlx5e: Update IPsec per SA packets/bytes count") Signed-off-by:

Currently, ingress acl is used for three features. It is created only when vport metadata match and prio tag are enabled. But active-backup lag mode also uses it. It is independent of vport metadata match and prio tag. And vport metadata match can be disabled using the following devlink command: # devlink dev param set pci/0000:08:00.0 name esw_port_metadata \ value false cmode runtime If ingress acl is not created, will hit panic when creating drop rule for active-backup lag mode. If always create it, there will be about 5% performance degradation. Fix it by creating ingress acl when needed. If esw_port_metadata is true, ingress acl exists, then create drop rule using existing ingress acl. If esw_port_metadata is false, create ingress acl and then create drop rule.

In some production workloads we noticed that connections could sometimes close extremely prematurely with ETIMEDOUT after transmitting only 1 TLP and RTO retransmission (when we would normally expect roughly tcp_retries2 = TCP_RETR2 = 15 RTOs before a connection closes with ETIMEDOUT). From tracing we determined that these workloads can suffer from a scenario where in fast recovery, after some retransmits, a DSACK undo can happen at a point where the scoreboard is totally clear (we have retrans_out == sacked_out == lost_out == 0). In such cases, calling tcp_try_keep_open() means that we do not execute any code path that clears tp->retrans_stamp to 0. That means that tp->retrans_stamp can remain erroneously set to the start time of the undone fast recovery, even after the fast recovery is undone. If minutes or hours elapse, and then a TLP/RTO/RTO sequence occurs, then the start_ts value in retransmits_timed_out() (which is from tp->retrans_stamp) will be erroneously ancient (left over from the fast recovery undone via DSACKs). Thus this ancient tp->retrans_stamp value can cause the connection to die very prematurely with ETIMEDOUT via tcp_write_err(). The fix: we change DSACK undo in fast recovery (TCP_CA_Recovery) to call tcp_try_to_open() instead of tcp_try_keep_open(). This ensures that if no retransmits are in flight at the time of DSACK undo in fast recovery then we properly zero retrans_stamp. Note that calling tcp_try_to_open() is more consistent with other loss recovery behavior, since normal fast recovery (CA_Recovery) and RTO recovery (CA_Loss) both normally end when tp->snd_una meets or exceeds tp->high_seq and then in tcp_fastretrans_alert() the "default" switch case executes tcp_try_to_open(). Also note that by inspection this change to call tcp_try_to_open() implies at least one other nice bug fix, where now an ECE-marked DSACK that causes an undo will properly invoke tcp_enter_cwr() rather than ignoring the ECE mark.
