2024-10-20x86/kvm: Override default caching mode for SEV-SNP and TDXKirill A. Shutemov
AMD SEV-SNP and Intel TDX have limited access to MTRR: either it is not advertised in CPUID or it cannot be programmed (on TDX, due to #VE on CR0.CD clear). This results in guests using uncached mappings where it shouldn't and pmd/pud_set_huge() failures due to non-uniform memory type reported by mtrr_type_lookup(). Override MTRR state, making it WB by default as the kernel does for Hyper-V guests. Signed-off-by: Kirill A.

2024-10-20drm: panel: nv3052c: correct spi_device_id for RG35XX panelRyan Walklin
The Anbernic RG35XX devices use an SPI LCD panel from an unknown OEM, with an NV3052C driver chip. As discussed previously, the integrating vendor and device name are preferred instead of the OEM serial. A previous patch corrected the device tree binding and of_device_id in the NV3052C driver, however the spi_device_id also needs correction. Correct the spi_device_id for the RG35XX panel.

2024-10-19octeon_ep: Add SKB allocation failures handling in __octep_oq_process_rx()Aleksandr Mishin
build_skb() returns NULL in case of a memory allocation failure so handle it inside __octep_oq_process_rx() to avoid NULL pointer dereference. __octep_oq_process_rx() is called during NAPI polling by the driver. If skb allocation fails, keep on pulling packets out of the Rx DMA queue: we shouldn't break the polling immediately and thus falsely indicate to the octep_napi_poll() that the Rx pressure is going down. As there is no associated skb in this case, don't process the packets and don't push them up the network stack - they are skipped. Helper function is implemented to unmmap/flush all the fragment buffers used by the dropped packet. 'alloc_failures' counter is incremented to mark the skb allocation error in driver statistics.

2024-10-19net: phy: dp83822: Fix reset pin definitionsMichel Alex
This change fixes a rare issue where the PHY fails to detect a link due to incorrect reset behavior. The SW_RESET definition was incorrectly assigned to bit 14, which is the Digital Restart bit according to the datasheet. This commit corrects SW_RESET to bit 15 and assigns DIG_RESTART to bit 14 as per the datasheet specifications. The SW_RESET define is only used in the phy_reset function, which fully re-initializes the PHY after the reset is performed. The change in the bit definitions should not have any negative impact on the functionality of the PHY. v2: - added Fixes tag - improved commit message Cc: stable@vger.kernel.org Fixes: 5dc39fd5ef35 ("net: phy: DP83822: Add ability to advertise Fiber connection") Signed-off-by: Alex Michel <alex.michel@wiedemann-group.com> Reviewed-by: Andrew Lunn <andrew@lunn.ch> Message-ID: <AS1P250MB0608A798661549BF83C4B43EA9462@AS1P250MB0608.EURP250.PROD.OUTLOOK.COM> Signed-off-by: Andrew Lunn <andrew@lunn.ch>

This means all function graph hooks that happen while that idle task is running (including in interrupt mode) will have all its events dropped. Switch over to the CPU hotplug mechanism that will have any newly brought on line CPU get a callback that can allocate the shadow stack for its idle task. - Fix allocation size of the ret_stack_list array When function graph tracing converted over to allowing more than one user at a time, it had to convert its shadow stack from an array of ret_stack structures to an array of unsigned longs. The shadow stacks are allocated in batches of 32 at a time and assigned to every running task. The batch is held by the ret_stack_list array. But when the conversion happened, instead of allocating an array of 32 pointers, it was allocated as a ret_stack itself (PAGE_SIZE). This ret_stack_list gets passed to a function that iterates over what it believes is its size defined by the FTRACE_RETSTACK_ALLOC_SIZE macro (which is 32). Luckily (PAGE_SIZE) is greater than 32 * sizeof(long), otherwise this would have been an array overflow. This still should be fixed and the ret_stack_list should be allocated to the size it is expected to be as someday it may end up being bigger than SHADOW_STACK_SIZE" * tag 'ftrace-v6.12-rc3' of git://git.kernel.org/pub/scm/linux/kernel/git/trace/linux-trace: fgraph: Allocate ret_stack_list with proper size fgraph: Use CPU hotplug mechanism to initialize idle shadow stacks

2024-10-18fgraph: Allocate ret_stack_list with proper sizeSteven Rostedt
The ret_stack_list is an array of ret_stack shadow stacks for the function graph usage. When the first function graph is enabled, all tasks in the system get a shadow stack. The ret_stack_list is a 32 element array of pointers to these shadow stacks. It allocates the shadow stack in batches (32 stacks at a time), assigns them to running tasks, and continues until all tasks are covered. When the function graph shadow stack changed from an array of ftrace_ret_stack structures to an array of longs, the allocation of ret_stack_list went from allocating an array of 32 elements to just a block defined by SHADOW_STACK_SIZE. Luckily, that's defined as PAGE_SIZE and is much more than enough to hold 32 pointers. But it is way overkill for the amount needed to allocate. Change the allocation of ret_stack_list back to a kcalloc() of FTRACE_RETSTACK_ALLOC_SIZE pointers.

2024-10-18fgraph: Use CPU hotplug mechanism to initialize idle shadow stacksSteven Rostedt
The function graph infrastructure allocates a shadow stack for every task when enabled. This includes the idle tasks. The first time the function graph is invoked, the shadow stacks are created and never freed until the task exits. This includes the idle tasks. Only the idle tasks that were for online CPUs had their shadow stacks created when function graph tracing started. If function graph tracing is enabled and a CPU comes online, the idle task representing that CPU will not have its shadow stack created, and all function graph tracing for that idle task will be silently dropped. Instead, use the CPU hotplug mechanism to allocate the idle shadow stacks. This will include idle tasks for CPUs that come online during tracing. This issue can be reproduced by: # cd /sys/kernel/tracing # echo 0 > /sys/devices/system/cpu/cpu1/online # echo 0 > set_ftrace_pid # echo function_graph > current_tracer # echo 1 > options/funcgraph-proc # echo 1 > /sys/devices/system/cpu/cpu1 # grep '<idle>' per_cpu/cpu1/trace | head Before, nothing would show up. After: 1) <idle>-0 | 0.811 us | __enqueue_entity(); 1) <idle>-0 | 5.626 us | } /* enqueue_entity */ 1) <idle>-0 | | dl_server_update_idle_time() { 1) <idle>-0 | | dl_scaled_delta_exec() { 1) <idle>-0 | 0.450 us | arch_scale_cpu_capacity(); 1) <idle>-0 | 1.242 us | } 1) <idle>-0 | 1.908 us | } 1) <idle>-0 | | dl_server_start() { 1) <idle>-0 | | enqueue_dl_entity() { 1) <idle>-0 | | task_contending() { Note, if tracing stops and restarts, the old way would then initialize the onlined CPUs.

2024-10-18nfsd: fix race between laundromat and free_stateidOlga Kornievskaia
There is a race between laundromat handling of revoked delegations and a client sending free_stateid operation. Laundromat thread finds that delegation has expired and needs to be revoked so it marks the delegation stid revoked and it puts it on a reaper list but then it unlock the state lock and the actual delegation revocation happens without the lock. Once the stid is marked revoked a racing free_stateid processing thread does the following (1) it calls list_del_init() which removes it from the reaper list and (2) frees the delegation stid structure. The laundromat thread ends up not calling the revoke_delegation() function for this particular delegation but that means it will no release the lock lease that exists on the file. Now, a new open for this file comes in and ends up finding that lease list isn't empty and calls nfsd_breaker_owns_lease() which ends up trying to derefence a freed delegation stateid. Leading to the followint use-after-free KASAN warning: kernel: ================================================================== kernel: BUG: KASAN: slab-use-after-free in nfsd_breaker_owns_lease+0x140/0x160 [nfsd] kernel: Read of size 8 at addr ffff0000e73cd0c8 by task nfsd/6205 kernel: kernel: CPU: 2 UID: 0 PID: 6205 Comm: nfsd Kdump: loaded Not tainted 6.11.0-rc7+ #9 kernel: Hardware name: Apple Inc.

First to make sure, that once the stid is marked revoked, it is not removed by the nfsd4_free_stateid(), the laundromat take a reference on the stateid. Then, coordinating whether the stid has been put on the cl_revoked list or we are processing FREE_STATEID and need to make sure to remove it from the list, each check that state and act accordingly. If laundromat has added to the cl_revoke list before the arrival of FREE_STATEID, then nfsd4_free_stateid() knows to remove it from the list. If nfsd4_free_stateid() finds that operations arrived before laundromat has placed it on cl_revoke list, it marks the state freed and then laundromat will no longer add it to the list. Also, for nfsd4_delegreturn() when looking for the specified stid, we need to access stid that are marked removed or freeable, it means the laundromat has started processing it but hasn't finished and this delegreturn needs to return nfserr_deleg_revoked and not nfserr_bad_stateid. The latter will not trigger a FREE_STATEID and the lack of it will leave this stid on the cl_revoked list indefinitely.

2024-10-18accel/qaic: Pass string literal as format argument of alloc_workqueue()Simon Horman
Recently I noticed that both gcc-14 and clang-18 report that passing a non-string literal as the format argument of alloc_workqueue() is potentially insecure. E.g. clang-18 says: .../qaic_drv.c:61:23: warning: format string is not a string literal (potentially insecure) [-Wformat-security] 61 | wq = alloc_workqueue(fmt, WQ_UNBOUND, 0); | ^~~ .../qaic_drv.c:61:23: note: treat the string as an argument to avoid this 61 | wq = alloc_workqueue(fmt, WQ_UNBOUND, 0); | ^ | "%s", It is always the case where the contents of fmt is safe to pass as the format argument. That is, in my understanding, it never contains any format escape sequences. But, it seems better to be safe than sorry. And, as a bonus, compiler output becomes less verbose by addressing this issue as suggested by clang-18. Also, change the name of the parameter of qaicm_wq_init from fmt to name to better reflect it's purpose. Compile tested only.
