2024-08-30Bluetooth: hci_sync: Introduce hci_cmd_sync_run/hci_cmd_sync_run_onceLuiz Augusto von Dentz
This introduces hci_cmd_sync_run/hci_cmd_sync_run_once which acts like hci_cmd_sync_queue/hci_cmd_sync_queue_once but runs immediately when already on hdev->cmd_sync_work context. Signed-off-by: Luiz Augusto von Dentz <luiz.von.dentz@intel.com>
2024-08-30Bluetooth: qca: If memdump doesn't work, re-enable IBSDouglas Anderson
On systems in the field, we are seeing this sometimes in the kernel logs: Bluetooth: qca_controller_memdump() hci0: hci_devcd_init Return:-95 This means that _something_ decided that it wanted to get a memdump but then hci_devcd_init() returned -EOPNOTSUPP (AKA -95). The cleanup code in qca_controller_memdump() when we get back an error from hci_devcd_init() undoes most things but forgets to clear QCA_IBS_DISABLED. One side effect of this is that, during the next suspend, qca_suspend() will always get a timeout. Let's fix it so that we clear the bit.

2024-08-30can: kvaser_pciefd: Use a single write when releasing RX buffersMartin Jocic
Kvaser's PCIe cards uses the KCAN FPGA IP block which has dual 4K buffers for incoming messages shared by all (currently up to eight) channels. While the driver processes messages in one buffer, new incoming messages are stored in the other and so on. The design of KCAN is such that a buffer must be fully read and then released. Releasing a buffer will make the FPGA switch buffers. If the other buffer contains at least one incoming message the FPGA will also instantly issue a new interrupt, if not the interrupt will be issued after receiving the first new message. With IRQx interrupts, it takes a little time for the interrupt to happen, enough for any previous ISR call to do it's business and return, but MSI interrupts are way faster so this time is reduced to almost nothing. So with MSI, releasing the buffer HAS to be the very last action of the ISR before returning, otherwise the new interrupt might be "masked" by the kernel because the previous ISR call hasn't returned. And the interrupts are edge-triggered so we cannot loose one, or the ping-pong reading process will stop. This is why this patch modifies the driver to use a single write to the SRB_CMD register before returning.

2024-08-30can: kvaser_usb: Simplify with dev_err_probe()Yan Zhen
dev_err_probe() is used to log an error message during the probe process of a device. It can simplify the error path and unify a message template. Using this helper is totally fine even if err is known to never be -EPROBE_DEFER. The benefit compared to a normal dev_err() is the standardized format of the error code, it being emitted symbolically and the fact that the error code is returned which allows more compact error paths.

2024-08-30can: netlink: avoid call to do_set_data_bittiming callback with stale ↵Stefan Mätje
can_priv::ctrlmode This patch moves the evaluation of data[IFLA_CAN_CTRLMODE] in function can_changelink in front of the evaluation of data[IFLA_CAN_BITTIMING]. This avoids a call to do_set_data_bittiming providing a stale can_priv::ctrlmode with a CAN_CTRLMODE_FD flag not matching the requested state when switching between a CAN Classic and CAN-FD bitrate. In the same manner the evaluation of data[IFLA_CAN_CTRLMODE] in function can_validate is also moved in front of the evaluation of data[IFLA_CAN_BITTIMING]. This is a preparation for patches where the nominal and data bittiming may have interdependencies on the driver side depending on the CAN_CTRLMODE_FD flag state.

2024-08-30e1000e: avoid failing the system during pm_suspendVitaly Lifshits
Occasionally when the system goes into pm_suspend, the suspend might fail due to a PHY access error on the network adapter. Previously, this would have caused the whole system to fail to go to a low power state. An example of this was reported in the following Bugzilla: https://bugzilla.kernel.org/show_bug.cgi?id=205015 [ 1663.694828] e1000e 0000:00:19.0 eth0: Failed to disable ULP [ 1664.731040] asix 2-3:1.0 eth1: link up, 100Mbps, full-duplex, lpa 0xC1E1 [ 1665.093513] e1000e 0000:00:19.0 eth0: Hardware Error [ 1665.596760] e1000e 0000:00:19.0: pci_pm_resume+0x0/0x80 returned 0 after 2975399 usecs and then the system never recovers from it, and all the following suspend failed due to this [22909.393854] PM: pci_pm_suspend(): e1000e_pm_suspend+0x0/0x760 [e1000e] returns -2 [22909.393858] PM: dpm_run_callback(): pci_pm_suspend+0x0/0x160 returns -2 [22909.393861] PM: Device 0000:00:1f.6 failed to suspend async: error -2 This can be avoided by changing the return values of __e1000_shutdown and e1000e_pm_suspend functions so that they always return 0 (success). This is consistent with what other drivers do. If the e1000e driver encounters a hardware error during suspend, potential side effects include slightly higher power draw or non-working wake on LAN. This is preferred to a system-level suspend failure, and a warning message is written to the system log, so that the user can be aware that the LAN controller experienced a problem during suspend.

2024-08-30Merge branch 'icmp-avoid-possible-side-channels-attacks'Jakub Kicinski
Eric Dumazet says: ==================== icmp: avoid possible side-channels attacks Keyu Man reminded us that linux ICMP rate limiting was still allowing side-channels attacks. Quoting the fine document [1]: 4.4 Private Source Port Scan Method ... We can then use the same global ICMP rate limit as a side channel to infer if such an ICMP message has been triggered. At first glance, this method can work but at a low speed of one port per second, due to the per-IP rate limit on ICMP messages. Surprisingly, after we analyze the source code of the ICMP rate limit implementation, we find that the global rate limit is checked prior to the per-IP rate limit. This means that even if the per-IP rate limit may eventually determine that no ICMP reply should be sent, a packet is still subjected to the global rate limit check and one token is deducted. Ironically, such a decision is consciously made by Linux developers to avoid invoking the expensive check of the per-IP rate limit [ 22], involving a search process to locate the per-IP data structure. This effectively means that the per-IP rate limit can be disre- garded for the purpose of our side channel based scan, as it only determines if the final ICMP reply is generated but has nothing to do with the global rate limit counter decrement. As a result, we can continue to use roughly the same scan method as efficient as before, achieving 1,000 ports per second ... This series : 1) Changes the order of the two rate limiters to fix the issue. 2-3) Make the 'host-wide' rate limiter a per-netns one.

2024-08-30icmp: change the order of rate limitsEric Dumazet
ICMP messages are ratelimited : After the blamed commits, the two rate limiters are applied in this order: 1) host wide ratelimit (icmp_global_allow()) 2) Per destination ratelimit (inetpeer based) In order to avoid side-channels attacks, we need to apply the per destination check first. This patch makes the following change : 1) icmp_global_allow() checks if the host wide limit is reached. But credits are not yet consumed. This is deferred to 3) 2) The per destination limit is checked/updated. This might add a new node in inetpeer tree. 3) icmp_global_consume() consumes tokens if prior operations succeeded. This means that host wide ratelimit is still effective in keeping inetpeer tree small even under DDOS. As a bonus, I removed icmp_global.lock as the fast path can use a lock-free operation.

2024-08-30igc: Get rid of spurious interruptsKurt Kanzenbach
When running the igc with XDP/ZC in busy polling mode with deferral of hard interrupts, interrupts still happen from time to time. That is caused by the igc task watchdog which triggers Rx interrupts periodically. That mechanism has been introduced to overcome skb/memory allocation failures [1]. So the Rx clean functions stop processing the Rx ring in case of such failure. The task watchdog triggers Rx interrupts periodically in the hope that memory became available in the mean time. The current behavior is undesirable for real time applications, because the driver induced Rx interrupts trigger also the softirq processing. However, all real time packets should be processed by the application which uses the busy polling method. Therefore, only trigger the Rx interrupts in case of real allocation failures. Introduce a new flag for signaling that condition.

2024-08-30igc: Add MQPRIO offload supportKurt Kanzenbach
Add support for offloading MQPRIO. The hardware has four priorities as well as four queues. Each queue must be a assigned with a unique priority. However, the priorities are only considered in TSN Tx mode. There are two TSN Tx modes. In case of MQPRIO the Qbv capability is not required. Therefore, use the legacy TSN Tx mode, which performs strict priority arbitration. Example for mqprio with hardware offload: |tc qdisc replace dev ${INTERFACE} handle 100 parent root mqprio num_tc 4 \ | map 0 0 0 0 0 1 2 3 0 0 0 0 0 0 0 0 \ | queues 1@0 1@1 1@2 1@3 \ | hw 1 The mqprio Qdisc also allows to configure the `preemptible_tcs'.

2024-08-30io_uring/rsrc: ensure compat iovecs are copied correctlyJens Axboe
For buffer registration (or updates), a userspace iovec is copied in and updated. If the application is within a compat syscall, then the iovec type is compat_iovec rather than iovec. However, the type used in __io_sqe_buffers_update() and io_sqe_buffers_register() is always struct iovec, and hence the source is incremented by the size of a non-compat iovec in the loop. This misses every other iovec in the source, and will run into garbage half way through the copies and return -EFAULT to the application. Maintain the source address separately and assign to our user vec pointer, so that copies always happen from the right source address. While in there, correct a bad placement of __user which triggered the following sparse warning prior to this fix: io_uring/rsrc.c:981:33: warning: cast removes address space '__user' of expression io_uring/rsrc.c:981:30: warning: incorrect type in assignment (different address spaces) io_uring/rsrc.c:981:30: expected struct iovec const [noderef] __user *uvec io_uring/rsrc.c:981:30: got struct iovec *[noderef] __user Fixes: f4eaf8eda89e ("io_uring/rsrc: Drop io_copy_iov in favor of iovec API") Reviewed-by: Gabriel Krisman Bertazi <krisman@suse.de> Signed-off-by: Jens Axboe <axboe@kernel.dk>

The latter clears the invalidated bit of a partial pages rather than discarding it entirely.

2024-08-30drm: komeda: Fix an issue related to normalized zposhongchi.peng
We use komeda_crtc_normalize_zpos to normalize zpos of affected planes to their blending zorder in CU. If there's only one slave plane in affected planes and its layer_split property is enabled, order++ for its split layer, so that when calculating the normalized_zpos of master planes, the split layer of the slave plane is included, but the max_slave_zorder does not include the split layer and keep zero because there's only one slave plane in affacted planes, although we actually use two slave layers in this commit. In most cases, this bug does not result in a commit failure, but assume the following situation: slave_layer 0: zpos = 0, layer split enabled, normalized_zpos = 0;(use slave_layer 2 as its split layer) master_layer 0: zpos = 2, layer_split enabled, normalized_zpos = 2;(use master_layer 2 as its split layer) master_layer 1: zpos = 4, normalized_zpos = 4; master_layer 3: zpos = 5, normalized_zpos = 5; kcrtc_st->max_slave_zorder = 0; When we use master_layer 3 as a input of CU in function komeda_compiz_set_input and check it with function komeda_component_check_input, the parameter idx is equal to normailzed_zpos minus max_slave_zorder, the value of idx is 5 and is euqal to CU's max_active_inputs, so that komeda_component_check_input returns a -EINVAL value. To fix the bug described above, when calculating the max_slave_zorder with the layer_split enabled, count the split layer in this calculation directly.

2024-08-30net/smc: prevent NULL pointer dereference in txopt_getJeongjun Park
Since smc_inet6_prot does not initialize ipv6_pinfo_offset, inet6_create() copies an incorrect address value, sk + 0 (offset), to inet_sk(sk)->pinet6. In addition, since inet_sk(sk)->pinet6 and smc_sk(sk)->clcsock practically point to the same address, when smc_create_clcsk() stores the newly created clcsock in smc_sk(sk)->clcsock, inet_sk(sk)->pinet6 is corrupted into clcsock. This causes NULL pointer dereference and various other memory corruptions. To solve this problem, you need to initialize ipv6_pinfo_offset, add a smc6_sock structure, and then add ipv6_pinfo as the second member of the smc_sock structure.

I divided the original driver into MAC and PHY drivers and implemented a QT2025 PHY driver in Rust. The MAC driver for Tehuti Networks TN40xx chips was already merged in 6.11-rc1. The MAC and this PHY drivers have been tested with Edimax EN-9320SFP+ 10G network adapter.

The first patch adds Rust equivalent to include/linux/sizes.h, makes code more readable. The 2-5th patches update the PHYLIB Rust bindings. The 4th and 5th patches have been reviewed previously in a different thread [1]. QT2025 PHY support was implemented as a part of an Ethernet driver for Tehuti Networks TN40xx chips. Multiple vendors (DLink, Asus, Edimax, QNAP, etc) developed adapters based on TN40xx chips. Tehuti Networks went out of business and the driver wasn't merged into mainline. But it's still distributed with some of the hardware (and also available on some vendor sites). The original driver handles multiple PHY hardware (AMCC QT2025, TI TLK10232, Aqrate AQR105, and Marvell MV88X3120, MV88X3310, and MV88E2010). I divided the original driver into MAC and PHY drivers and implemented a QT2025 PHY driver in Rust. The MAC driver for Tehuti Networks TN40xx chips was already merged in 6.11-rc1. The MAC and this PHY drivers have been tested with Edimax EN-9320SFP+ 10G network adapter.

This driver supports Applied Micro Circuits Corporation QT2025 PHY, based on a driver for Tehuti Networks TN40xx chips. The original driver for TN40xx chips supports multiple PHY hardware (AMCC QT2025, TI TLK10232, Aqrate AQR105, and Marvell 88X3120, 88X3310, and MV88E2010). This driver is extracted from the original driver and modified to a PHY driver in Rust. This has been tested with Edimax EN-9320SFP+ 10G network adapter.
