2023-11-13net: mvneta: fix calls to page_pool_get_statsSven Auhagen1-8/+20
Calling page_pool_get_stats in the mvneta driver without checks leads to kernel crashes. First the page pool is only available if the bm is not used. The page pool is also not allocated when the port is stopped. It can also be not allocated in case of errors. The current implementation leads to the following crash calling ethstats on a port that is down or when calling it at the wrong moment: ble to handle kernel NULL pointer dereference at virtual address 00000070 [00000070] *pgd=00000000 Internal error: Oops: 5 [#1] SMP ARM Hardware name: Marvell Armada 380/385 (Device Tree) PC is at page_pool_get_stats+0x18/0x1cc LR is at mvneta_ethtool_get_stats+0xa0/0xe0 [mvneta] pc : [<c0b413cc>] lr : [<bf0a98d8>] psr: a0000013 sp : f1439d48 ip : f1439dc0 fp : 0000001d r10: 00000100 r9 : c4816b80 r8 : f0d75150 r7 : bf0b400c r6 : c238f000 r5 : 00000000 r4 : f1439d68 r3 : c2091040 r2 : ffffffd8 r1 : f1439d68 r0 : 00000000 Flags: NzCv IRQs on FIQs on Mode SVC_32 ISA ARM Segment none Control: 10c5387d Table: 066b004a DAC: 00000051 Register r0 information: NULL pointer Register r1 information: 2-page vmalloc region starting at 0xf1438000 allocated at kernel_clone+0x9c/0x390 Register r2 information: non-paged memory Register r3 information: slab kmalloc-2k start c2091000 pointer offset 64 size 2048 Register r4 information: 2-page vmalloc region starting at 0xf1438000 allocated at kernel_clone+0x9c/0x390 Register r5 information: NULL pointer Register r6 information: slab kmalloc-cg-4k start c238f000 pointer offset 0 size 4096 Register r7 information: 15-page vmalloc region starting at 0xbf0a8000 allocated at load_module+0xa30/0x219c Register r8 information: 1-page vmalloc region starting at 0xf0d75000 allocated at ethtool_get_stats+0x138/0x208 Register r9 information: slab task_struct start c4816b80 pointer offset 0 Register r10 information: non-paged memory Register r11 information: non-paged memory Register r12 information: 2-page vmalloc region starting at 0xf1438000 allocated at kernel_clone+0x9c/0x390 Process snmpd (pid: 733, stack limit = 0x38de3a88) Stack: (0xf1439d48 to 0xf143a000) 9d40: 000000c0 00000001 c238f000 bf0b400c f0d75150 c4816b80 9d60: 00000100 bf0a98d8 00000000 00000000 00000000 00000000 00000000 00000000 9d80: 00000000 00000000 00000000 00000000 00000000 00000000 00000000 00000000 9da0: 00000000 00000000 00000000 00000000 00000000 00000000 00000000 00000000 9dc0: 00000dc0 5335509c 00000035 c238f000 bf0b2214 01067f50 f0d75000 c0b9b9c8 9de0: 0000001d 00000035 c2212094 5335509c c4816b80 c238f000 c5ad6e00 01067f50 9e00: c1b0be80 c4816b80 00014813 c0b9d7f0 00000000 00000000 0000001d 0000001d 9e20: 00000000 00001200 00000000 00000000 c216ed90 c73943b8 00000000 00000000 9e40: 00000000 00000000 00000000 00000000 00000000 00000000 00000000 00000000 9e60: 00000000 c0ad9034 00000000 00000000 00000000 00000000 00000000 00000000 9e80: 00000000 00000000 00000000 5335509c c1b0be80 f1439ee4 00008946 c1b0be80 9ea0: 01067f50 f1439ee3 00000000 00000046 b6d77ae0 c0b383f0 00008946 becc83e8 9ec0: c1b0be80 00000051 0000000b c68ca480 c7172d00 c0ad8ff0 f1439ee3 cf600e40 9ee0: 01600e40 32687465 00000000 00000000 00000000 01067f50 00000000 00000000 9f00: 00000000 5335509c 00008946 00008946 00000000 c68ca480 becc83e8 c05e2de0 9f20: f1439fb0 c03002f0 00000006 5ac3c35a c4816b80 00000006 b6d77ae0 c030caf0 9f40: c4817350 00000014 f1439e1c 0000000c 00000000 00000051 01000000 00000014 9f60: 00003fec f1439edc 00000001 c0372abc b6d77ae0 c0372abc cf600e40 5335509c 9f80: c21e6800 01015c9c 0000000b 00008946 00000036 c03002f0 c4816b80 00000036 9fa0: b6d77ae0 c03000c0 01015c9c 0000000b 0000000b 00008946 becc83e8 00000000 9fc0: 01015c9c 0000000b 00008946 00000036 00000035 010678a0 b6d797ec b6d77ae0 9fe0: b6dbf738 becc838c b6d186d7 b6baa858 40000030 0000000b 00000000 00000000 page_pool_get_stats from mvneta_ethtool_get_stats+0xa0/0xe0 [mvneta] mvneta_ethtool_get_stats [mvneta] from ethtool_get_stats+0x154/0x208 ethtool_get_stats from dev_ethtool+0xf48/0x2480 dev_ethtool from dev_ioctl+0x538/0x63c dev_ioctl from sock_ioctl+0x49c/0x53c sock_ioctl from sys_ioctl+0x134/0xbd8 sys_ioctl from ret_fast_syscall+0x0/0x1c Exception stack(0xf1439fa8 to 0xf1439ff0) 9fa0: 01015c9c 0000000b 0000000b 00008946 becc83e8 00000000 9fc0: 01015c9c 0000000b 00008946 00000036 00000035 010678a0 b6d797ec b6d77ae0 9fe0: b6dbf738 becc838c b6d186d7 b6baa858 Code: e28dd004 e1a05000 e2514000 0a00006a (e5902070) This commit adds the proper checks before calling page_pool_get_stats.

2023-11-13i2c: designware: Fix corrupted memory seen in the ISRJan Bottorff1-8/+8
When running on a many core ARM64 server, errors were happening in the ISR that looked like corrupted memory. These corruptions would fix themselves if small delays were inserted in the ISR. Errors reported by the driver included "i2c_designware APMC0D0F:00: i2c_dw_xfer_msg: invalid target address" and "i2c_designware APMC0D0F:00:controller timed out" during in-band IPMI SSIF stress tests. The problem was determined to be memory writes in the driver were not becoming visible to all cores when execution rapidly shifted between cores, like when a register write immediately triggers an ISR. Processors with weak memory ordering, like ARM64, make no guarantees about the order normal memory writes become globally visible, unless barrier instructions are used to control ordering. To solve this, regmap accessor functions configured by this driver were changed to use non-relaxed forms of the low-level register access functions, which include a barrier on platforms that require it. This assures memory writes before a controller register access are visible to all cores. The community concluded defaulting to correct operation outweighed defaulting to the small performance gains from using relaxed access functions. Being a low speed device added weight to this choice of default register access behavior.

2023-11-13net: hns3: fix VF wrong speed and duplex issueJijie Shao1-0/+4
If PF is down, firmware will returns 10 Mbit/s rate and half-duplex mode when PF queries the port information from firmware. After imp reset command is executed, PF status changes to down, and PF will query link status and updates port information from firmware in a periodic scheduled task. However, there is a low probability that port information is updated when PF is down, and then PF link status changes to up. In this case, PF synchronizes incorrect rate and duplex mode to VF. This patch fixes it by updating port information before PF synchronizes the rate and duplex to the VF when PF changes to up.

2023-11-13net: hns3: fix VF reset fail issueJijie Shao2-1/+14
Currently the reset process in hns3 and firmware watchdog init process is asynchronous. We think firmware watchdog initialization is completed before VF clear the interrupt source. However, firmware initialization may not complete early. So VF will receive multiple reset interrupts and fail to reset. So we add delay before VF interrupt source and 5 ms delay is enough to avoid second reset interrupt.

2023-11-13acpi/processor: sanitize _OSC/_PDC capabilities for Xen dom0Roger Pau Monne1-0/+22
The Processor capability bits notify ACPI of the OS capabilities, and so ACPI can adjust the return of other Processor methods taking the OS capabilities into account. When Linux is running as a Xen dom0, the hypervisor is the entity in charge of processor power management, and hence Xen needs to make sure the capabilities reported by _OSC/_PDC match the capabilities of the driver in Xen. Introduce a small helper to sanitize the buffer when running as Xen dom0. When Xen supports HWP, this serves as the equivalent of commit a21211672c9a ("ACPI / processor: Request native thermal interrupt handling via _OSC") to avoid SMM crashes. Xen will set bit ACPI_PROC_CAP_COLLAB_PROC_PERF (bit 12) in the capability bits and the _OSC/_PDC call will apply it. [ jandryuk: Mention Xen HWP's need.

2023-11-13xen/events: avoid using info_for_irq() in xen_send_IPI_one()Juergen Gross1-4/+8
xen_send_IPI_one() is being used by cpuhp_report_idle_dead() after it calls rcu_report_dead(), meaning that any RCU usage by xen_send_IPI_one() is a bad idea. Unfortunately xen_send_IPI_one() is using notify_remote_via_irq() today, which is using irq_get_chip_data() via info_for_irq(). And irq_get_chip_data() in turn is using a maple-tree lookup requiring RCU. Avoid this problem by caching the ipi event channels in another percpu variable, allowing the use notify_remote_via_evtchn() in xen_send_IPI_one().

2023-11-10spi: Fix null dereference on suspendMark Hasemeyer1-17/+39
A race condition exists where a synchronous (noqueue) transfer can be active during a system suspend. This can cause a null pointer dereference exception to occur when the system resumes. Example order of events leading to the exception: 1. spi_sync() calls __spi_transfer_message_noqueue() which sets ctlr->cur_msg 2. Spi transfer begins via spi_transfer_one_message() 3. System is suspended interrupting the transfer context 4. System is resumed 6. spi_controller_resume() calls spi_start_queue() which resets cur_msg to NULL 7. Spi transfer context resumes and spi_finalize_current_message() is called which dereferences cur_msg (which is now NULL) Wait for synchronous transfers to complete before suspending by acquiring the bus mutex and setting/checking a suspend flag.

2023-11-10ipvlan: add ipvlan_route_v6_outbound() helperEric Dumazet1-16/+25
Inspired by syzbot reports using a stack of multiple ipvlan devices. Reduce stack size needed in ipvlan_process_v6_outbound() by moving the flowi6 struct used for the route lookup in an non inlined helper. ipvlan_route_v6_outbound() needs 120 bytes on the stack, immediately reclaimed. Also make sure ipvlan_process_v4_outbound() is not inlined. We might also have to lower MAX_NEST_DEV, because only syzbot uses setups with more than four stacked devices.

2023-11-10fbdev: amifb: Convert to platform remove callback returning voidUwe Kleine-König1-3/+2
The .remove() callback for a platform driver returns an int which makes many driver authors wrongly assume it's possible to do error handling by returning an error code. However the value returned is ignored (apart from emitting a warning) and this typically results in resource leaks. To improve here there is a quest to make the remove callback return void. In the first step of this quest all drivers are converted to .remove_new(), which already returns void. Eventually after all drivers are converted, .remove_new() will be renamed to .remove(). Trivially convert this driver from always returning zero in the remove callback to the void returning variant.
