2022-10-24net/mlx5e: Cleanup MACsec uninitialization routineLeon Romanovsky1-10/+1
The mlx5e_macsec_cleanup() routine has NULL pointer dereferencing if mlx5 device doesn't support MACsec (priv->macsec will be NULL). While at it delete comment line, assignment and extra blank lines, so fix everything in one patch.

2022-10-24platform/x86/amd: pmc: Read SMU version during suspend on Cezanne systemsMario Limonciello1-0/+7
commit b0c07116c894 ("platform/x86: amd-pmc: Avoid reading SMU version at probe time") adjusted the behavior for amd-pmc to avoid reading the SMU version at startup but rather on first use to improve boot time. However the SMU version is also used to decide whether to place a timer based wakeup in the OS_HINT message. If the idlemask hasn't been read before this message was sent then the SMU version will not have been cached. Ensure the SMU version has been read before deciding whether or not to run this codepath.

2022-10-24atlantic: fix deadlock at aq_nic_stopÍñigo Huguet2-24/+74
NIC is stopped with rtnl_lock held, and during the stop it cancels the 'service_task' work and free irqs. However, if CONFIG_MACSEC is set, rtnl_lock is acquired both from aq_nic_service_task and aq_linkstate_threaded_isr. Then a deadlock happens if aq_nic_stop tries to cancel/disable them when they've already started their execution. As the deadlock is caused by rtnl_lock, it causes many other processes to stall, not only atlantic related stuff. Fix it by introducing a mutex that protects each NIC's macsec related data, and locking it instead of the rtnl_lock from the service task and the threaded IRQ. Before this patch, all macsec data was protected with rtnl_lock, but maybe not all of it needs to be protected. With this new mutex, further efforts can be made to limit the protected data only to that which requires it. However, probably it doesn't worth it because all macsec's data accesses are infrequent, and almost all are done from macsec_ops or ethtool callbacks, called holding rtnl_lock, so macsec_mutex won't never be much contended. The issue appeared repeteadly attaching and deattaching the NIC to a bond interface. Doing that after this patch I cannot reproduce the bug.

2022-10-24drm/i915/dgfx: Keep PCI autosuspend control 'on' by default on all dGPUAnshuman Gupta1-2/+9
DGFX platforms has lmem and cpu can access the lmem objects via mmap and i915 internal i915_gem_object_pin_map() for i915 own usages. Both of these methods has pre-requisite requirement to keep GFX PCI endpoint in D0 for a supported iomem transaction over PCI link. (Refer PCIe specs 5.3.1.4.1) Both DG1/DG2 have a known hardware bug that violates the PCIe specs and support the iomem read write transaction over PCIe bus despite endpoint is D3 state. Due to above H/W bug, we had never observed any issue with i915 runtime PM versus lmem access. But this issue becomes visible when PCIe gfx endpoint's upstream bridge enters to D3, at this point any lmem read/write access will be returned as unsupported request. But again this issue is not observed on every platform because it has been observed on few host machines DG1/DG2 endpoint's upstream bridge does not bind with pcieport driver. which really disables the PCIe power savings and leaves the bridge at D0 state. We need a unique interface to read/write from lmem with runtime PM wakeref protection something similar to intel_uncore_{read, write}, keep autosuspend control to 'on' on all discrete platforms, until we have a unique interface to read/write from lmem. This just change the default autosuspend setting of i915 on dGPU, user can still change it to 'auto'. v2: - Modified the commit message and subject with more information. - Changed the Fixes tag to LMEM support commit.

2022-10-24mac802154: Fix LQI recordingMiquel Raynal1-2/+3
Back in 2014, the LQI was saved in the skb control buffer (skb->cb, or mac_cb(skb)) without any actual reset of this area prior to its use. As part of a useful rework of the use of this region, 32edc40ae65c ("ieee802154: change _cb handling slightly") introduced mac_cb_init() to basically memset the cb field to 0. In particular, this new function got called at the beginning of mac802154_parse_frame_start(), right before the location where the buffer got actually filled. What went through unnoticed however, is the fact that the very first helper called by device drivers in the receive path already used this area to save the LQI value for later extraction. Resetting the cb field "so late" led to systematically zeroing the LQI. If we consider the reset of the cb field needed, we can make it as soon as we get an skb from a device driver, right before storing the LQI, as is the very first time we need to write something there.

Since `sp_indiff` is the application firmware property, it should only be cleaned when the firmware is unloaded. Now let management firmware to clean it when necessary, driver only set it.

Raju Rangoju says: ==================== amd-xgbe: Miscellaneous fixes (1) Fix the rrc for Yellow carp devices. CDR workaround path is disabled for YC devices, receiver reset cycle is not needed in such cases. (2) Add enumerations for mailbox command and sub-commands. Instead of using hard-coded values, use enums. (3) Enable PLL_CTL for fixed PHY modes only. Driver does not implement SW RRCM for Autoneg Off configuration, hence PLL is needed for fixed PHY modes only. (4) Fix the SFP compliance codes check for DAC cables. Some of the passive cables have non-zero data at offset 6 in SFP EEPROM data. So, fix the sfp compliance codes check.

2022-10-21amd-xgbe: add the bit rate quirk for Molex cablesRaju Rangoju1-1/+8
The offset 12 (bit-rate) of EEPROM SFP DAC (passive) cables is expected to be in the range 0x64 to 0x68. However, the 5 meter and 7 meter Molex passive cables have the rate ceiling 0x78 at offset 12. Add a quirk for Molex passive cables to extend the rate ceiling to 0x78.

2022-10-21amd-xgbe: fix the SFP compliance codes check for DAC cablesRaju Rangoju1-4/+4
The current XGBE code assumes that offset 6 of EEPROM SFP DAC (passive) cables is NULL. However, some cables (the 5 meter and 7 meter Molex passive cables) have non-zero data at offset 6. Fix the logic by moving the passive cable check above the active checks, so as not to be improperly identified as an active cable. This will fix the issue for any passive cable that advertises 1000Base-CX in offset 6.

2022-10-21amd-xgbe: enable PLL_CTL for fixed PHY modes onlyRaju Rangoju1-2/+8
PLL control setting(RRC) is needed only in fixed PHY configuration to fix the peer-peer issues. Without the PLL control setting, the link up takes longer time in a fixed phy configuration. Driver implements SW RRC for Autoneg On configuration, hence PLL control setting (RRC) is not needed for AN On configuration, and can be skipped. Also, PLL re-initialization is not needed for PHY Power Off and RRC commands. Otherwise, they lead to mailbox errors. Added the changes accordingly.

2022-10-21Merge branch 'Wait for busy refill_work when destroying bpf memory allocator'Alexei Starovoitov1-2/+16
Hou Tao says: ==================== From: Hou Tao <[email protected]> Hi, The patchset aims to fix one problem of bpf memory allocator destruction when there is PREEMPT_RT kernel or kernel with arch_irq_work_has_interrupt() being false (e.g. 1-cpu arm32 host or mips). The root cause is that there may be busy refill_work when the allocator is destroying and it may incur oops or other problems as shown in patch #1. Patch #1 fixes the problem by waiting for the completion of irq work during destroying and patch #2 is just a clean-up patch based on patch #1. Please see individual patches for more details. Comments are always welcome. Change Log: v2: * patch 1: fix typos and add notes about the overhead of irq_work_sync() * patch 1 & 2: add Acked-by tags from [email protected] v1: https://lore.kernel.org/bpf/[email protected]/T/#t ==================== Signed-off-by: Alexei Starovoitov <[email protected]>
2022-10-21bpf: Use __llist_del_all() whenever possbile during memory drainingHou Tao1-2/+5
Except for waiting_for_gp list, there are no concurrent operations on free_by_rcu, free_llist and free_llist_extra lists, so use __llist_del_all() instead of llist_del_all(). waiting_for_gp list can be deleted by RCU callback concurrently, so still use llist_del_all().

2022-10-21bpf: Wait for busy refill_work when destroying bpf memory allocatorHou Tao1-0/+11
A busy irq work is an unfinished irq work and it can be either in the pending state or in the running state. When destroying bpf memory allocator, refill_work may be busy for PREEMPT_RT kernel in which irq work is invoked in a per-CPU RT-kthread. It is also possible for kernel with arch_irq_work_has_interrupt() being false (e.g. 1-cpu arm32 host or mips) and irq work is inovked in timer interrupt. The busy refill_work leads to various issues. The obvious one is that there will be concurrent operations on free_by_rcu and free_list between irq work and memory draining. Another one is call_rcu_in_progress will not be reliable for the checking of pending RCU callback because do_call_rcu() may have not been invoked by irq work yet. The other is there will be use-after-free if irq work is freed before the callback of irq work is invoked as shown below: BUG: kernel NULL pointer dereference, address: 0000000000000000 #PF: supervisor instruction fetch in kernel mode #PF: error_code(0x0010) - not-present page PGD 12ab94067 P4D 12ab94067 PUD 1796b4067 PMD 0 Oops: 0010 [#1] PREEMPT_RT SMP CPU: 5 PID: 64 Comm: irq_work/5 Not tainted 6.0.0-rt11+ #1 Hardware name: QEMU Standard PC (i440FX + PIIX, 1996) RIP: 0010:0x0 Code: Unable to access opcode bytes at 0xffffffffffffffd6.
