2024-09-10drm: new helper: drm_gem_prime_handle_to_dmabuf()Al Viro
Once something had been put into descriptor table, the only thing you can do with it is returning descriptor to userland - you can't withdraw it on subsequent failure exit, etc. You certainly can't count upon it staying in the same slot of descriptor table - another thread could've played with close(2)/dup2(2)/whatnot. drm_gem_prime_handle_to_fd() creates a dmabuf, allocates a descriptor and attaches dmabuf's file to it (the last two steps are done in dma_buf_fd()). That's nice when all you are going to do is passing a descriptor to userland. If you just need to work with the resulting object or have something else to be done that might fail, drm_gem_prime_handle_to_fd() is racy. The problem is analogous to one with anon_inode_getfd(), and solution is similar to what anon_inode_getfile() provides. Add drm_gem_prime_handle_to_dmabuf() - the "set dmabuf up" parts of drm_gem_prime_handle_to_fd() without the descriptor-related ones. Instead of inserting into descriptor table and returning the file descriptor it just returns the struct file. drm_gem_prime_handle_to_fd() becomes a wrapper for it. Other users will be introduced in the next commit.

2024-09-05drm/panthor: Restrict high priorities on group_createMary Guillemard
We were allowing any users to create a high priority group without any permission checks. As a result, this was allowing possible denial of service. We now only allow the DRM master or users with the CAP_SYS_NICE capability to set higher priorities than PANTHOR_GROUP_PRIORITY_MEDIUM. As the sole user of that uAPI lives in Mesa and hardcode a value of MEDIUM [1], this should be safe to do. Additionally, as those checks are performed at the ioctl level, panthor_group_create now only check for priority level validity.

2024-09-04kvm: Note an RCU quiescent state on guest exitLeonardo Bras
As of today, KVM notes a quiescent state only in guest entry, which is good as it avoids the guest being interrupted for current RCU operations. While the guest vcpu runs, it can be interrupted by a timer IRQ that will check for any RCU operations waiting for this CPU. In case there are any of such, it invokes rcu_core() in order to sched-out the current thread and note a quiescent state. This occasional schedule work will introduce tens of microsseconds of latency, which is really bad for vcpus running latency-sensitive applications, such as real-time workloads. So, note a quiescent state in guest exit, so the interrupted guests is able to deal with any pending RCU operations before being required to invoke rcu_core(), and thus avoid the overhead of related scheduler work.

While at it: add a new interface for initializing the pwrctl context where we'd now assign the parent device address and initialize the workqueue.

2024-09-03bpf, net: Fix a potential race in do_sock_getsockopt()Tze-nan Wu
There's a potential race when `cgroup_bpf_enabled(CGROUP_GETSOCKOPT)` is false during the execution of `BPF_CGROUP_GETSOCKOPT_MAX_OPTLEN`, but becomes true when `BPF_CGROUP_RUN_PROG_GETSOCKOPT` is called. This inconsistency can lead to `BPF_CGROUP_RUN_PROG_GETSOCKOPT` receiving an "-EFAULT" from `__cgroup_bpf_run_filter_getsockopt(max_optlen=0)`. Scenario shown as below: `process A` `process B` ----------- ------------ BPF_CGROUP_GETSOCKOPT_MAX_OPTLEN enable CGROUP_GETSOCKOPT BPF_CGROUP_RUN_PROG_GETSOCKOPT (-EFAULT) To resolve this, remove the `BPF_CGROUP_GETSOCKOPT_MAX_OPTLEN` macro and directly uses `copy_from_sockptr` to ensure that `max_optlen` is always set before `BPF_CGROUP_RUN_PROG_GETSOCKOPT` is invoked.

git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip Pull x86 fixes from Thomas Gleixner: - x2apic_disable() clears x2apic_state and x2apic_mode unconditionally, even when the state is X2APIC_ON_LOCKED, which prevents the kernel to disable it thereby creating inconsistent state. Reorder the logic so it actually works correctly - The XSTATE logic for handling LBR is incorrect as it assumes that XSAVES supports LBR when the CPU supports LBR. In fact both conditions need to be true. Otherwise the enablement of LBR in the IA32_XSS MSR fails and subsequently the machine crashes on the next XRSTORS operation because IA32_XSS is not initialized. Cache the XSTATE support bit during init and make the related functions use this cached information and the LBR CPU feature bit to cure this. - Cure a long standing bug in KASLR KASLR uses the full address space between PAGE_OFFSET and vaddr_end to randomize the starting points of the direct map, vmalloc and vmemmap regions. It thereby limits the size of the direct map by using the installed memory size plus an extra configurable margin for hot-plug memory. This limitation is done to gain more randomization space because otherwise only the holes between the direct map, vmalloc, vmemmap and vaddr_end would be usable for randomizing. The limited direct map size is not exposed to the rest of the kernel, so the memory hot-plug and resource management related code paths still operate under the assumption that the available address space can be determined with MAX_PHYSMEM_BITS. request_free_mem_region() allocates from (1 << MAX_PHYSMEM_BITS) - 1 downwards. That means the first allocation happens past the end of the direct map and if unlucky this address is in the vmalloc space, which causes high_memory to become greater than VMALLOC_START and consequently causes iounmap() to fail for valid ioremap addresses. Cure this by exposing the end of the direct map via PHYSMEM_END and use that for the memory hot-plug and resource management related places instead of relying on MAX_PHYSMEM_BITS. In the KASLR case PHYSMEM_END maps to a variable which is initialized by the KASLR initialization and otherwise it is based on MAX_PHYSMEM_BITS as before. - Prevent a data leak in mmio_read(). The TDVMCALL exposes the value of an initialized variabled on the stack to the VMM. The variable is only required as output value, so it does not have to exposed to the VMM in the first place. - Prevent an array overrun in the resource control code on systems with Sub-NUMA Clustering enabled because the code failed to adjust the index by the number of SNC nodes per L3 cache. * tag 'x86-urgent-2024-09-01' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip: x86/resctrl: Fix arch_mbm_* array overrun on SNC x86/tdx: Fix data leak in mmio_read() x86/kaslr: Expose and use the end of the physical memory address space x86/fpu: Avoid writing LBR bit to IA32_XSS unless supported x86/apic: Make x2apic_disable() work correctly

2024-08-28netfs, cifs: Fix handling of short DIO readDavid Howells
Short DIO reads, particularly in relation to cifs, are not being handled correctly by cifs and netfslib. This can be tested by doing a DIO read of a file where the size of read is larger than the size of the file. When it crosses the EOF, it gets a short read and this gets retried, and in the case of cifs, the retry read fails, with the failure being translated to ENODATA. Fix this by the following means: (1) Add a flag, NETFS_SREQ_HIT_EOF, for the filesystem to set when it detects that the read did hit the EOF. (2) Make the netfslib read assessment stop processing subrequests when it encounters one with that flag set. (3) Return rreq->transferred, the accumulated contiguous amount read to that point, to userspace for a DIO read. (4) Make cifs set the flag and clear the error if the read RPC returned ENODATA. (5) Make cifs set the flag and clear the error if a short read occurred without error and the read-to file position is now at the remote inode size.

2024-08-28x86/resctrl: Fix arch_mbm_* array overrun on SNCPeter Newman
When using resctrl on systems with Sub-NUMA Clustering enabled, monitoring groups may be allocated RMID values which would overrun the arch_mbm_{local,total} arrays. This is due to inconsistencies in whether the SNC-adjusted num_rmid value or the unadjusted value in resctrl_arch_system_num_rmid_idx() is used. The num_rmid value for the L3 resource is currently: resctrl_arch_system_num_rmid_idx() / snc_nodes_per_l3_cache As a simple fix, make resctrl_arch_system_num_rmid_idx() return the SNC-adjusted, L3 num_rmid value on x86.

2024-08-27bonding: change ipsec_lock from spin lock to mutexJianbo Liu
In the cited commit, bond->ipsec_lock is added to protect ipsec_list, hence xdo_dev_state_add and xdo_dev_state_delete are called inside this lock. As ipsec_lock is a spin lock and such xfrmdev ops may sleep, "scheduling while atomic" will be triggered when changing bond's active slave.

And bond_ipsec_add_sa and bond_ipsec_del_sa are xfrm state xdo_dev_state_add and xdo_dev_state_delete APIs, which are in user context. So ipsec_lock doesn't have to be spin lock, change it to mutex, and thus the above issue can be resolved.
