2024-06-19drm/i915/psr: Set SU area width as pipe src widthJouni Högander
Currently SU area width is set as MAX_INT. This is causing problems. Instead set it as pipe src width.

2024-06-18cifs: drop the incorrect assertion in cifs_swap_rw()Barry Song
Since commit 2282679fb20b ("mm: submit multipage write for SWP_FS_OPS swap-space"), we can plug multiple pages then unplug them all together. That means iov_iter_count(iter) could be way bigger than PAGE_SIZE, it actually equals the size of iov_iter_npages(iter, INT_MAX). Note this issue has nothing to do with large folios as we don't support THP_SWPOUT to non-block devices.

2024-06-18net: phy: dp83tg720: get master/slave configuration in link down stateOleksij Rempel
Get master/slave configuration for initial system start with the link in down state. This ensures ethtool shows current configuration. Also fixes link reconfiguration with ethtool while in down state, preventing ethtool from displaying outdated configuration. Even though dp83tg720_config_init() is executed periodically as long as the link is in admin up state but no carrier is detected, this is not sufficient for the link in admin down state where dp83tg720_read_status() is not periodically executed.

2024-06-18spi: Fix SPI slave probe failureAmit Kumar Mahapatra
While adding a SPI device, the SPI core ensures that multiple logical CS doesn't map to the same physical CS. For example, spi->chip_select[0] != spi->chip_select[1] and so forth. However, unlike the SPI master, the SPI slave doesn't have the list of chip selects, this leads to probe failure when the SPI controller is configured as slave. Update the __spi_add_device() function to perform this check only if the SPI controller is configured as master.

In Xe, the plan is to support multiple types of perf counter streams (OA is only one type of these streams). Rather than introduce NxM ioctls for these (N perf streams with M ioctl's per perf stream), we decide to multiplex these (N different stream types and the M ops for each of these stream types) through a single PERF ioctl. This multiplexing is the purpose of the PERF layer. In addition to PERF DRM ioctl's, another set of ioctl's on the PERF fd are defined.

2024-06-18cpumask: limit FORCE_NR_CPUS to just the UP caseLinus Torvalds
Hardcoding the number of CPUs at compile time does improve code generation, but if you get it wrong the result will be confusion. We already limited this earlier to only "experts" (see commit fe5759d5bfda "cpumask: limit visibility of FORCE_NR_CPUS"), but with distro kernel configs often having EXPERT enabled, that turns out to not be much of a limit. To quote the philosophers at Disney: "Everyone can be an expert. And when everyone's an expert, no one will be". There's a runtime warning if you then set nr_cpus to anything but the forced number, but apparently that can be ignored too [1] and by then it's pretty much too late anyway. If we had some real way to limit this to "embedded only", maybe it would be worth it, but let's see if anybody even notices that the option is gone. We need to simplify kernel configuration anyway.

2024-06-18KVM: Stop processing *all* memslots when "null" mmu_notifier handler is foundBabu Moger
Bail from outer address space loop, not just the inner memslot loop, when a "null" handler is encountered by __kvm_handle_hva_range(), which is the intended behavior. On x86, which has multiple address spaces thanks to SMM emulation, breaking from just the memslot loop results in undefined behavior due to assigning the non-existent return value from kvm_null_fn() to a bool. In practice, the bug is benign as kvm_mmu_notifier_invalidate_range_end() is the only caller that passes handler=kvm_null_fn, and it doesn't set flush_on_ret, i.e. assigning garbage to r.ret is ultimately ignored. And for most configuration the compiler elides the entire sequence, i.e. there is no undefined behavior at runtime. ------------[ cut here ]------------ UBSAN: invalid-load in arch/x86/kvm/../../../virt/kvm/kvm_main.c:655:10 load of value 160 is not a valid value for type '_Bool' CPU: 370 PID: 8246 Comm: CPU 0/KVM Not tainted 6.8.2-amdsos-build58-ubuntu-22.04+ #1 Hardware name: AMD Corporation Sh54p/Sh54p, BIOS WPC4429N 04/25/2024 Call Trace: <TASK> dump_stack_lvl+0x48/0x60 ubsan_epilogue+0x5/0x30 __ubsan_handle_load_invalid_value+0x79/0x80 kvm_mmu_notifier_invalidate_range_end.cold+0x18/0x4f [kvm] __mmu_notifier_invalidate_range_end+0x63/0xe0 __split_huge_pmd+0x367/0xfc0 do_huge_pmd_wp_page+0x1cc/0x380 __handle_mm_fault+0x8ee/0xe50 handle_mm_fault+0xe4/0x4a0 __get_user_pages+0x190/0x840 get_user_pages_unlocked+0xe0/0x590 hva_to_pfn+0x114/0x550 [kvm] kvm_faultin_pfn+0xed/0x5b0 [kvm] kvm_tdp_page_fault+0x123/0x170 [kvm] kvm_mmu_page_fault+0x244/0xaa0 [kvm] vcpu_enter_guest+0x592/0x1070 [kvm] kvm_arch_vcpu_ioctl_run+0x145/0x8a0 [kvm] kvm_vcpu_ioctl+0x288/0x6d0 [kvm] __x64_sys_ioctl+0x8f/0xd0 do_syscall_64+0x77/0x120 entry_SYSCALL_64_after_hwframe+0x6e/0x76 </TASK> ---[ end trace ]--- Fixes: 071064f14d87 ("KVM: Don't take mmu_lock for range invalidation unless necessary") Signed-off-by: Babu Moger <babu.moger@amd.com> Link: https://lore.kernel.org/r/b8723d39903b64c241c50f5513f804390c7b5eec.1718203311.git.babu.moger@amd.com [sean: massage changelog] Signed-off-by: Sean Christopherson <seanjc@google.com>

2024-06-18sched: act_ct: add netns into the key of tcf_ct_flow_tableXin Long
zones_ht is a global hashtable for flow_table with zone as key. However, it does not consider netns when getting a flow_table from zones_ht in tcf_ct_init(), and it means an act_ct action in netns A may get a flow_table that belongs to netns B if it has the same zone value. In Shuang's test with the TOPO: tcf2_c <---> tcf2_sw1 <---> tcf2_sw2 <---> tcf2_s tcf2_sw1 and tcf2_sw2 saw the same flow and used the same flow table, which caused their ct entries entering unexpected states and the TCP connection not able to end normally. This patch fixes the issue simply by adding netns into the key of tcf_ct_flow_table so that an act_ct action gets a flow_table that belongs to its own netns in tcf_ct_init(). Note that for easy coding we don't use tcf_ct_flow_table.nf_ft.net, as the ct_ft is initialized after inserting it to the hashtable in tcf_ct_flow_table_get() and also it requires to implement several functions in rhashtable_params including hashfn, obj_hashfn and obj_cmpfn.
