d6c5f06 Hengqi Chen 09 December 2023, 07:49:15 UTC LoongArch: Preserve syscall nr across execve() Currently, we store syscall nr in pt_regs::regs[11] and syscall execve() accidentally overrides it during its execution: sys_execve() -> do_execve() -> do_execveat_common() -> bprm_execve() -> exec_binprm() -> search_binary_handler() -> load_elf_binary() -> ELF_PLAT_INIT() ELF_PLAT_INIT() reset regs[11] to 0, so in syscall_exit_to_user_mode() we later get a wrong syscall nr. This breaks tools like execsnoop since it relies on execve() tracepoints. Skip pt_regs::regs[11] reset in ELF_PLAT_INIT() to fix the issue.

97ceddb Jinyang He 09 December 2023, 07:49:15 UTC LoongArch: Set unwind stack type to unknown rather than set error flag During unwinding, unwind_done() is used as an end condition. Normally it unwind to the user stack and then set the stack type to unknown, which is a normal exit. When something unexpected happens in unwind process and we cannot unwind anymore, we should set the error flag, and also set the stack type to unknown to indicate that the unwind process can not continue. The error flag emphasizes that the unwind process produce an unexpected error. There is no unexpected things when we unwind the PT_REGS in the top of IRQ stack and find out that is an user mode PT_REGS. Thus, we should not set error flag and just set stack type to unknown.

eea673e WANG Rui 09 December 2023, 07:49:15 UTC LoongArch: Apply dynamic relocations for LLD For the following assembly code: .text .global func func: nop .data var: .dword func When linked with `-pie`, GNU LD populates the `var` variable with the pre-relocated value of `func`. However, LLVM LLD does not exhibit the same behavior. This issue also arises with the `kernel_entry` in arch/ loongarch/kernel/head.S: _head: .word MZ_MAGIC /* "MZ", MS-DOS header */ .org 0x8 .dword kernel_entry /* Kernel entry point */ The correct kernel entry from the MS-DOS header is crucial for jumping to vmlinux from zboot. This necessity is why the compressed relocatable kernel compiled by Clang encounters difficulties in booting. To address this problem, it is proposed to apply dynamic relocations to place with `--apply-dynamic-relocs`.

4cdf351 Sean Christopherson 07 May 2021, 16:59:46 UTC KVM: SVM: Update EFER software model on CR0 trap for SEV-ES In general, activating long mode involves setting the EFER_LME bit in the EFER register and then enabling the X86_CR0_PG bit in the CR0 register. At this point, the EFER_LMA bit will be set automatically by hardware. In the case of SVM/SEV guests where writes to CR0 are intercepted, it's necessary for the host to set EFER_LMA on behalf of the guest since hardware does not see the actual CR0 write. In the case of SEV-ES guests where writes to CR0 are trapped instead of intercepted, the hardware *does* see/record the write to CR0 before exiting and passing the value on to the host, so as part of enabling SEV-ES support commit f1c6366e3043 ("KVM: SVM: Add required changes to support intercepts under SEV-ES") dropped special handling of the EFER_LMA bit with the understanding that it would be set automatically. However, since the guest never explicitly sets the EFER_LMA bit, the host never becomes aware that it has been set. This becomes problematic when userspace tries to get/set the EFER values via KVM_GET_SREGS/KVM_SET_SREGS, since the EFER contents tracked by the host will be missing the EFER_LMA bit, and when userspace attempts to pass the EFER value back via KVM_SET_SREGS it will fail a sanity check that asserts that EFER_LMA should always be set when X86_CR0_PG and EFER_LME are set. Fix this by always inferring the value of EFER_LMA based on X86_CR0_PG and EFER_LME, regardless of whether or not SEV-ES is enabled.

When instances started allowing latency tracers, it uses a snapshot buffer (another buffer that is not written to but swapped with the main buffer that is). The snapshot buffer needs to be the same size as the main buffer. But when the snapshot buffers were added to instances, the code to make the snapshot equal to the main buffer still was only doing it for the main buffer and not the instances. 2. Need to stop the current tracer when resizing the buffers. Otherwise there can be a race if the tracer decides to make a snapshot between resizing the main buffer and the snapshot buffer. 3. When a tracer is "stopped" in disables both the main buffer and the snapshot buffer. This needs to be done for instances and not only the main buffer, now that instances also have a snapshot buffer. - Buffered event for filtering issues: When filtering is enabled, because events can be dropped often, it is quicker to copy the event into a temp buffer and write that into the main buffer if it is not filtered or just drop the event if it is, than to write the event into the ring buffer and then try to discard it. This temp buffer is allocated and needs special synchronization to do so. But there were some issues with that: 1. When disabling the filter and freeing the buffer, a call to all CPUs is required to stop each per_cpu usage. But the code called smp_call_function_many() which does not include the current CPU. If the task is migrated to another CPU when it enables the CPUs via smp_call_function_many(), it will not enable the one it is currently on and this causes issues later on. Use on_each_cpu_mask() instead, which includes the current CPU. 2.When the allocation of the buffered event fails, it can give a warning. But the buffered event is just an optimization (it's still OK to write to the ring buffer and free it). Do not WARN in this case. 3.The freeing of the buffer event requires synchronization. First a counter is decremented to zero so that no new uses of it will happen. Then it sets the buffered event to NULL, and finally it frees the buffered event. There's a synchronize_rcu() between the counter decrement and the setting the variable to NULL, but only a smp_wmb() between that and the freeing of the buffer. It is theoretically possible that a user missed seeing the decrement, but will use the buffer after it is free. Another synchronize_rcu() is needed in place of that smp_wmb(). - ring buffer timestamps on 32 bit machines The ring buffer timestamp on 32 bit machines has to break the 64 bit number into multiple values as cmpxchg is required on it, and a 64 bit cmpxchg on 32 bit architectures is very slow. The code use to just use two 32 bit values and make it a 60 bit timestamp where the other 4 bits were used as counters for synchronization. It later came known that the timestamp on 32 bit still need all 64 bits in some cases. So 3 words were created to handle the 64 bits. But issues arised with this: 1. The synchronization logic still only compared the counter with the first two, but not with the third number, so the synchronization could fail unknowingly. 2. A check on discard of an event could race if an event happened between the discard and updating one of the counters. The counter needs to be updated (forcing an absolute timestamp and not to use a delta) before the actual discard happens. * tag 'trace-v6.7-rc4' of git://git.kernel.org/pub/scm/linux/kernel/git/trace/linux-trace: ring-buffer: Test last update in 32bit version of __rb_time_read() ring-buffer: Force absolute timestamp on discard of event tracing: Fix a possible race when disabling buffered events tracing: Fix a warning when allocating buffered events fails tracing: Fix incomplete locking when disabling buffered events tracing: Disable snapshot buffer when stopping instance tracers tracing: Stop current tracer when resizing buffer tracing: Always update snapshot buffer size 08 December 2023, 16:44:43 UTC

Loop between 2 - 4, then mddev_suspend() will be called quite often, for consequence, normal IO will be quite slow. Fix this problem by don't set MD_RECOVERY_NEEDED again in md_start_sync(), hence the loop will be broken.

e037818 Ido Schimmel 06 December 2023, 21:31:02 UTC drop_monitor: Require 'CAP_SYS_ADMIN' when joining "events" group The "NET_DM" generic netlink family notifies drop locations over the "events" multicast group. This is problematic since by default generic netlink allows non-root users to listen to these notifications. Fix by adding a new field to the generic netlink multicast group structure that when set prevents non-root users or root without the 'CAP_SYS_ADMIN' capability (in the user namespace owning the network namespace) from joining the group. Set this field for the "events" group. Use 'CAP_SYS_ADMIN' rather than 'CAP_NET_ADMIN' because of the nature of the information that is shared over this group. Note that the capability check in this case will always be performed against the initial user namespace since the family is not netns aware and only operates in the initial network namespace. A new field is added to the structure rather than using the "flags" field because the existing field uses uAPI flags and it is inappropriate to add a new uAPI flag for an internal kernel check. In net-next we can rework the "flags" field to use internal flags and fold the new field into it. But for now, in order to reduce the amount of changes, add a new field. Since the information can only be consumed by root, mark the control plane operations that start and stop the tracing as root-only using the 'GENL_ADMIN_PERM' flag. Tested using [1].

f4116bf Kirill A. Shutemov 04 December 2023, 08:31:41 UTC x86/tdx: Allow 32-bit emulation by default 32-bit emulation was disabled on TDX to prevent a possible attack by a VMM injecting an interrupt on vector 0x80. Now that int80_emulation() has a check for external interrupts the limitation can be lifted. To distinguish software interrupts from external ones, int80_emulation() checks the APIC ISR bit relevant to the 0x80 vector. For software interrupts, this bit will be 0. On TDX, the VAPIC state (including ISR) is protected and cannot be manipulated by the VMM. The ISR bit is set by the microcode flow during the handling of posted interrupts.

The kernel expects to receive a software interrupt as a result of the INT 0x80 instruction. However, an external interrupt on the same vector also triggers the same codepath. An external interrupt on vector 0x80 will currently be interpreted as a 32-bit system call, and assuming that it was a user context. Panic on external interrupts on the vector. To distinguish software interrupts from external ones, the kernel checks the APIC ISR bit relevant to the 0x80 vector. For software interrupts, this bit will be 0.

be5341e Thomas Gleixner 04 December 2023, 08:31:39 UTC x86/entry: Convert INT 0x80 emulation to IDTENTRY There is no real reason to have a separate ASM entry point implementation for the legacy INT 0x80 syscall emulation on 64-bit. IDTENTRY provides all the functionality needed with the only difference that it does not: - save the syscall number (AX) into pt_regs::orig_ax - set pt_regs::ax to -ENOSYS Both can be done safely in the C code of an IDTENTRY before invoking any of the syscall related functions which depend on this convention. Aside of ASM code reduction this prepares for detecting and handling a local APIC injected vector 0x80.

b82a8db Kirill A. Shutemov 04 December 2023, 08:31:38 UTC x86/coco: Disable 32-bit emulation by default on TDX and SEV The INT 0x80 instruction is used for 32-bit x86 Linux syscalls. The kernel expects to receive a software interrupt as a result of the INT 0x80 instruction. However, an external interrupt on the same vector triggers the same handler. The kernel interprets an external interrupt on vector 0x80 as a 32-bit system call that came from userspace. A VMM can inject external interrupts on any arbitrary vector at any time. This remains true even for TDX and SEV guests where the VMM is untrusted. Put together, this allows an untrusted VMM to trigger int80 syscall handling at any given point. The content of the guest register file at that moment defines what syscall is triggered and its arguments. It opens the guest OS to manipulation from the VMM side. Disable 32-bit emulation by default for TDX and SEV. User can override it with the ia32_emulation=y command line option.

3d501dd Eric Dumazet 05 December 2023, 16:18:41 UTC tcp: do not accept ACK of bytes we never sent This patch is based on a detailed report and ideas from Yepeng Pan and Christian Rossow. ACK seq validation is currently following RFC 5961 5.2 guidelines: The ACK value is considered acceptable only if it is in the range of ((SND.UNA - MAX.SND.WND) <= SEG.ACK <= SND.NXT). All incoming segments whose ACK value doesn't satisfy the above condition MUST be discarded and an ACK sent back. It needs to be noted that RFC 793 on page 72 (fifth check) says: "If the ACK is a duplicate (SEG.ACK < SND.UNA), it can be ignored. If the ACK acknowledges something not yet sent (SEG.ACK > SND.NXT) then send an ACK, drop the segment, and return". The "ignored" above implies that the processing of the incoming data segment continues, which means the ACK value is treated as acceptable. This mitigation makes the ACK check more stringent since any ACK < SND.UNA wouldn't be accepted, instead only ACKs that are in the range ((SND.UNA - MAX.SND.WND) <= SEG.ACK <= SND.NXT) get through. This can be refined for new (and possibly spoofed) flows, by not accepting ACK for bytes that were never sent. This greatly improves TCP security at a little cost. I added a Fixes: tag to make sure this patch will reach stable trees, even if the 'blamed' patch was adhering to the RFC. tp->bytes_acked was added in linux-4.2 Following packetdrill test (courtesy of Yepeng Pan) shows the issue at hand: 0 socket(..., SOCK_STREAM, IPPROTO_TCP) = 3 +0 setsockopt(3, SOL_SOCKET, SO_REUSEADDR, [1], 4) = 0 +0 bind(3, ..., ...) = 0 +0 listen(3, 1024) = 0 // ---------------- Handshake ------------------- // // when window scale is set to 14 the window size can be extended to // 65535 * (2^14) = 1073725440.

The BMC provides KVM functionality via the USB gadget device: - before: KVM page refresh results in a broken USB device, - after: KVM page refresh works without any issues.

b2f557a Jiexun Wang 21 September 2023, 12:27:51 UTC mm/madvise: add cond_resched() in madvise_cold_or_pageout_pte_range() I conducted real-time testing and observed that madvise_cold_or_pageout_pte_range() causes significant latency under memory pressure, which can be effectively reduced by adding cond_resched() within the loop. I tested on the LicheePi 4A board using Cylictest for latency testing and Ftrace for latency tracing. The board uses TH1520 processor and has a memory size of 8GB. The kernel version is 6.5.0 with the PREEMPT_RT patch applied. The script I tested is as follows: echo wakeup_rt > /sys/kernel/tracing/current_tracer echo 1 > /sys/kernel/tracing/tracing_on echo 0 > /sys/kernel/tracing/tracing_max_latency stress-ng --vm 8 --vm-bytes 2G & cyclictest --mlockall --smp --priority=99 --distance=0 --duration=30m echo 0 > /sys/kernel/tracing/tracing_on cat /sys/kernel/tracing/trace The tracing results before modification are as follows: # tracer: wakeup_rt # # wakeup_rt latency trace v1.1.5 on 6.5.0-rt6-r1208-00003-g999d221864bf # -------------------------------------------------------------------- # latency: 2552 us, #6/6, CPU#3 | (M:preempt_rt VP:0, KP:0, SP:0 HP:0 #P:4) # ----------------- # | task: cyclictest-196 (uid:0 nice:0 policy:1 rt_prio:99) # ----------------- # # _--------=> CPU# # / _-------=> irqs-off/BH-disabled # | / _------=> need-resched # || / _-----=> need-resched-lazy # ||| / _----=> hardirq/softirq # |||| / _---=> preempt-depth # ||||| / _--=> preempt-lazy-depth # |||||| / _-=> migrate-disable # ||||||| / delay # cmd pid |||||||| time | caller # \ / |||||||| \ | / stress-n-206 3dn.h512 2us : 206:120:R + [003] 196: 0:R cyclictest stress-n-206 3dn.h512 7us : <stack trace> => __ftrace_trace_stack => __trace_stack => probe_wakeup => ttwu_do_activate => try_to_wake_up => wake_up_process => hrtimer_wakeup => __hrtimer_run_queues => hrtimer_interrupt => riscv_timer_interrupt => handle_percpu_devid_irq => generic_handle_domain_irq => riscv_intc_irq => handle_riscv_irq => do_irq stress-n-206 3dn.h512 9us#: 0 stress-n-206 3d...3.. 2544us : __schedule stress-n-206 3d...3.. 2545us : 206:120:R ==> [003] 196: 0:R cyclictest stress-n-206 3d...3.. 2551us : <stack trace> => __ftrace_trace_stack => __trace_stack => probe_wakeup_sched_switch => __schedule => preempt_schedule => migrate_enable => rt_spin_unlock => madvise_cold_or_pageout_pte_range => walk_pgd_range => __walk_page_range => walk_page_range => madvise_pageout => madvise_vma_behavior => do_madvise => sys_madvise => do_trap_ecall_u => ret_from_exception The tracing results after modification are as follows: # tracer: wakeup_rt # # wakeup_rt latency trace v1.1.5 on 6.5.0-rt6-r1208-00004-gca3876fc69a6-dirty # -------------------------------------------------------------------- # latency: 1689 us, #6/6, CPU#0 | (M:preempt_rt VP:0, KP:0, SP:0 HP:0 #P:4) # ----------------- # | task: cyclictest-217 (uid:0 nice:0 policy:1 rt_prio:99) # ----------------- # # _--------=> CPU# # / _-------=> irqs-off/BH-disabled # | / _------=> need-resched # || / _-----=> need-resched-lazy # ||| / _----=> hardirq/softirq # |||| / _---=> preempt-depth # ||||| / _--=> preempt-lazy-depth # |||||| / _-=> migrate-disable # ||||||| / delay # cmd pid |||||||| time | caller # \ / |||||||| \ | / stress-n-232 0dn.h413 1us+: 232:120:R + [000] 217: 0:R cyclictest stress-n-232 0dn.h413 12us : <stack trace> => __ftrace_trace_stack => __trace_stack => probe_wakeup => ttwu_do_activate => try_to_wake_up => wake_up_process => hrtimer_wakeup => __hrtimer_run_queues => hrtimer_interrupt => riscv_timer_interrupt => handle_percpu_devid_irq => generic_handle_domain_irq => riscv_intc_irq => handle_riscv_irq => do_irq stress-n-232 0dn.h413 19us#: 0 stress-n-232 0d...3.. 1671us : __schedule stress-n-232 0d...3.. 1676us+: 232:120:R ==> [000] 217: 0:R cyclictest stress-n-232 0d...3.. 1687us : <stack trace> => __ftrace_trace_stack => __trace_stack => probe_wakeup_sched_switch => __schedule => preempt_schedule => migrate_enable => free_unref_page_list => release_pages => free_pages_and_swap_cache => tlb_batch_pages_flush => tlb_flush_mmu => unmap_page_range => unmap_vmas => unmap_region => do_vmi_align_munmap.constprop.0 => do_vmi_munmap => __vm_munmap => sys_munmap => do_trap_ecall_u => ret_from_exception After the modification, the cause of maximum latency is no longer madvise_cold_or_pageout_pte_range(), so this modification can reduce the latency caused by madvise_cold_or_pageout_pte_range(). Currently the madvise_cold_or_pageout_pte_range() function exhibits significant latency under memory pressure, which can be effectively reduced by adding cond_resched() within the loop. When the batch_count reaches SWAP_CLUSTER_MAX, we reschedule the task to ensure fairness and avoid long lock holding times.

675abf8 Ryusuke Konishi 05 December 2023, 08:59:47 UTC nilfs2: prevent WARNING in nilfs_sufile_set_segment_usage() If nilfs2 reads a disk image with corrupted segment usage metadata, and its segment usage information is marked as an error for the segment at the write location, nilfs_sufile_set_segment_usage() can trigger WARN_ONs during log writing. Segments newly allocated for writing with nilfs_sufile_alloc() will not have this error flag set, but this unexpected situation will occur if the segment indexed by either nilfs->ns_segnum or nilfs->ns_nextnum (active segment) was marked in error. Fix this issue by inserting a sanity check to treat it as a file system corruption. Since error returns are not allowed during the execution phase where nilfs_sufile_set_segment_usage() is used, this inserts the sanity check into nilfs_sufile_mark_dirty() which pre-reads the buffer containing the segment usage record to be updated and sets it up in a dirty state for writing. In addition, nilfs_sufile_set_segment_usage() is also called when canceling log writing and undoing segment usage update, so in order to avoid issuing the same kernel warning in that case, in case of cancellation, avoid checking the error flag in nilfs_sufile_set_segment_usage().

This leads to multi index stores in the xarray which is only supporting through CONFIG_XARRAY_MULTI. The other page cache user of multi index stores ,THP, selects XARRAY_MULTI. Have CONFIG_HUGETLB_PAGE follow this behavior as well to avoid the BUG() with a CONFIG_HUGETLB_PAGE && !CONFIG_XARRAY_MULTI config.

d61d0ab Ryusuke Konishi 29 November 2023, 14:15:47 UTC nilfs2: fix missing error check for sb_set_blocksize call When mounting a filesystem image with a block size larger than the page size, nilfs2 repeatedly outputs long error messages with stack traces to the kernel log, such as the following: getblk(): invalid block size 8192 requested logical block size: 512 ... Call Trace: dump_stack_lvl+0x92/0xd4 dump_stack+0xd/0x10 bdev_getblk+0x33a/0x354 __breadahead+0x11/0x80 nilfs_search_super_root+0xe2/0x704 [nilfs2] load_nilfs+0x72/0x504 [nilfs2] nilfs_mount+0x30f/0x518 [nilfs2] legacy_get_tree+0x1b/0x40 vfs_get_tree+0x18/0xc4 path_mount+0x786/0xa88 __ia32_sys_mount+0x147/0x1a8 __do_fast_syscall_32+0x56/0xc8 do_fast_syscall_32+0x29/0x58 do_SYSENTER_32+0x15/0x18 entry_SYSENTER_32+0x98/0xf1 ... This overloads the system logger. And to make matters worse, it sometimes crashes the kernel with a memory access violation. This is because the return value of the sb_set_blocksize() call, which should be checked for errors, is not checked. The latter issue is due to out-of-buffer memory being accessed based on a large block size that caused sb_set_blocksize() to fail for buffers read with the initial minimum block size that remained unupdated in the super_block structure. Since nilfs2 mkfs tool does not accept block sizes larger than the system page size, this has been overlooked. However, it is possible to create this situation by intentionally modifying the tool or by passing a filesystem image created on a system with a large page size to a system with a smaller page size and mounting it. Fix this issue by inserting the expected error handling for the call to sb_set_blocksize().

dccf78d Baoquan He 28 November 2023, 05:44:57 UTC kernel/Kconfig.kexec: drop select of KEXEC for CRASH_DUMP Ignat Korchagin complained that a potential config regression was introduced by commit 89cde455915f ("kexec: consolidate kexec and crash options into kernel/Kconfig.kexec"). Before the commit, CONFIG_CRASH_DUMP has no dependency on CONFIG_KEXEC. After the commit, CRASH_DUMP selects KEXEC. That enforces system to have CONFIG_KEXEC=y as long as CONFIG_CRASH_DUMP=Y which people may not want. In Ignat's case, he sets CONFIG_CRASH_DUMP=y, CONFIG_KEXEC_FILE=y and CONFIG_KEXEC=n because kexec_load interface could have security issue if kernel/initrd has no chance to be signed and verified. CRASH_DUMP has select of KEXEC because Eric, author of above commit, met a LKP report of build failure when posting patch of earlier version. Please see below link to get detail of the LKP report: https://lore.kernel.org/all/3e8eecd1-a277-2cfb-690e-5de2eb7b988e@oracle.com/T/#u In fact, that LKP report is triggered because arm's <asm/kexec.h> is wrapped in CONFIG_KEXEC ifdeffery scope. That is wrong. CONFIG_KEXEC controls the enabling/disabling of kexec_load interface, but not kexec feature. Removing the wrongly added CONFIG_KEXEC ifdeffery scope in <asm/kexec.h> of arm allows us to drop the select KEXEC for CRASH_DUMP. Meanwhile, change arch/arm/kernel/Makefile to let machine_kexec.o relocate_kernel.o depend on KEXEC_CORE.
