git://git.kernel.org/pub/scm/linux/kernel/git/vfs/vfs Pull vfs fixes from Christian Brauner: "This contains a few small fixes for this merge window and the attempt to handle the ntfs removal regression that was reported a little while ago: - After the removal of the legacy ntfs driver we received reports about regressions for some people that do mount "ntfs" explicitly and expect the driver to be available. Since ntfs3 is a drop-in for legacy ntfs we alias legacy ntfs to ntfs3 just like ext3 is aliased to ext4. We also enforce legacy ntfs is always mounted read-only and give it custom file operations to ensure that ioctl()'s can't be abused to perform write operations. - Fix an unbalanced module_get() in bdev_open(). - Two smaller fixes for the netfs work done earlier in this cycle. - Fix the errno returned from the new FS_IOC_GETUUID and FS_IOC_GETFSSYSFSPATH ioctls. Both commands just pull information out of the superblock so there's no need to call into the actual ioctl handlers. So instead of returning ENOIOCTLCMD to indicate to fallback we just return ENOTTY directly avoiding that indirection" * tag 'vfs-6.9-rc6.fixes' of git://git.kernel.org/pub/scm/linux/kernel/git/vfs/vfs: netfs: Fix the pre-flush when appending to a file in writethrough mode netfs: Fix writethrough-mode error handling ntfs3: add legacy ntfs file operations ntfs3: enforce read-only when used as legacy ntfs driver ntfs3: serve as alias for the legacy ntfs driver block: fix module reference leakage from bdev_open_by_dev error path fs: Return ENOTTY directly if FS_IOC_GETUUID or FS_IOC_GETFSSYSFSPATH fail

2024-04-26Merge patch series "RISC-V: Test th.sxstatus.MAEE bit before enabling MAEE"Palmer Dabbelt
Christoph Müllner <christoph.muellner@vrull.eu> says: Currently, the Linux kernel suffers from a boot regression when running on the c906 QEMU emulation. Details have been reported here by Björn Töpel: https://lists.gnu.org/archive/html/qemu-devel/2024-01/msg04766.html The main issue is, that Linux enables XTheadMae for CPUs that have a T-Head mvendorid but QEMU maintainers don't want to emulate a CPU that uses reserved bits in PTEs. See also the following discussion for more context: https://lists.gnu.org/archive/html/qemu-devel/2024-02/msg00775.html This series renames "T-Head PBMT" to "MAE"/"XTheadMae" and only enables it if the th.sxstatus.MAEE bit is set.

2024-04-26selftests/bpf: Test PROBE_MEM of VSYSCALL_ADDR on x86-64Puranjay Mohan
The vsyscall is a legacy API for fast execution of system calls. It maps a page at address VSYSCALL_ADDR into the userspace program. This address is in the top 10MB of the address space: ffffffffff600000 - ffffffffff600fff | 4 kB | legacy vsyscall ABI The last commit fixes the x86-64 BPF JIT to skip accessing addresses in this memory region. Add this address to bpf_testmod_return_ptr() so we can make sure that it is fixed. After this change and without the previous commit, subprogs_extable selftest will crash the kernel.

2024-04-26bpf, x86: Fix PROBE_MEM runtime load checkPuranjay Mohan
When a load is marked PROBE_MEM - e.g. due to PTR_UNTRUSTED access - the address being loaded from is not necessarily valid. The BPF jit sets up exception handlers for each such load which catch page faults and 0 out the destination register. If the address for the load is outside kernel address space, the load will escape the exception handling and crash the kernel. To prevent this from happening, the emits some instruction to verify that addr is > end of userspace addresses. x86 has a legacy vsyscall ABI where a page at address 0xffffffffff600000 is mapped with user accessible permissions. The addresses in this page are considered userspace addresses by the fault handler. Therefore, a BPF program accessing this page will crash the kernel. This patch fixes the runtime checks to also check that the PROBE_MEM address is below VSYSCALL_ADDR. Example BPF program: SEC("fentry/tcp_v4_connect") int BPF_PROG(fentry_tcp_v4_connect, struct sock *sk) { *(volatile unsigned long *)&sk->sk_tsq_flags; return 0; } BPF Assembly: 0: (79) r1 = *(u64 *)(r1 +0) 1: (79) r1 = *(u64 *)(r1 +344) 2: (b7) r0 = 0 3: (95) exit x86-64 JIT ========== BEFORE AFTER ------ ----- 0: nopl 0x0(%rax,%rax,1) 0: nopl 0x0(%rax,%rax,1) 5: xchg %ax,%ax 5: xchg %ax,%ax 7: push %rbp 7: push %rbp 8: mov %rsp,%rbp 8: mov %rsp,%rbp b: mov 0x0(%rdi),%rdi b: mov 0x0(%rdi),%rdi ------------------------------------------------------------------------------- f: movabs $0x100000000000000,%r11 f: movabs $0xffffffffff600000,%r10 19: add $0x2a0,%rdi 19: mov %rdi,%r11 20: cmp %r11,%rdi 1c: add $0x2a0,%r11 23: jae 0x0000000000000029 23: sub %r10,%r11 25: xor %edi,%edi 26: movabs $0x100000000a00000,%r10 27: jmp 0x000000000000002d 30: cmp %r10,%r11 29: mov 0x0(%rdi),%rdi 33: ja 0x0000000000000039 --------------------------------\ 35: xor %edi,%edi 2d: xor %eax,%eax \ 37: jmp 0x0000000000000040 2f: leave \ 39: mov 0x2a0(%rdi),%rdi 30: ret \-------------------------------------------- 40: xor %eax,%eax 42: leave 43: ret Signed-off-by: Puranjay Mohan <puranjay@kernel.org> Link: https://lore.kernel.org/r/20240424100210.11982-3-puranjay@kernel.org Signed-off-by: Alexei Starovoitov <ast@kernel.org>
2024-04-26bpf: verifier: prevent userspace memory accessPuranjay Mohan
With BPF_PROBE_MEM, BPF allows de-referencing an untrusted pointer. To thwart invalid memory accesses, the JITs add an exception table entry for all such accesses. But in case the src_reg + offset is a userspace address, the BPF program might read that memory if the user has mapped it. Make the verifier add guard instructions around such memory accesses and skip the load if the address falls into the userspace region. The JITs need to implement bpf_arch_uaddress_limit() to define where the userspace addresses end for that architecture or TASK_SIZE is taken as default. The implementation is as follows: REG_AX = SRC_REG if(offset) REG_AX += offset; REG_AX >>= 32; if (REG_AX <= (uaddress_limit >> 32)) DST_REG = 0; else DST_REG = *(size *)(SRC_REG + offset); Comparing just the upper 32 bits of the load address with the upper 32 bits of uaddress_limit implies that the values are being aligned down to a 4GB boundary before comparison. The above means that all loads with address <= uaddress_limit + 4GB are skipped. This is acceptable because there is a large hole (much larger than 4GB) between userspace and kernel space memory, therefore a correctly functioning BPF program should not access this 4GB memory above the userspace. Let's analyze what this patch does to the following fentry program dereferencing an untrusted pointer: SEC("fentry/tcp_v4_connect") int BPF_PROG(fentry_tcp_v4_connect, struct sock *sk) { *(volatile long *)sk; return 0; } BPF Program before | BPF Program after ------------------ | ----------------- 0: (79) r1 = *(u64 *)(r1 +0) 0: (79) r1 = *(u64 *)(r1 +0) ----------------------------------------------------------------------- 1: (79) r1 = *(u64 *)(r1 +0) --\ 1: (bf) r11 = r1 ----------------------------\ \ 2: (77) r11 >>= 32 2: (b7) r0 = 0 \ \ 3: (b5) if r11 <= 0x8000 goto pc+2 3: (95) exit \ \-> 4: (79) r1 = *(u64 *)(r1 +0) \ 5: (05) goto pc+1 \ 6: (b7) r1 = 0 \-------------------------------------- 7: (b7) r0 = 0 8: (95) exit As you can see from above, in the best case (off=0), 5 extra instructions are emitted. Now, we analyze the same program after it has gone through the JITs of ARM64 and RISC-V architectures. We follow the single load instruction that has the untrusted pointer and see what instrumentation has been added around it. x86-64 JIT ========== JIT's Instrumentation (upstream) --------------------- 0: nopl 0x0(%rax,%rax,1) 5: xchg %ax,%ax 7: push %rbp 8: mov %rsp,%rbp b: mov 0x0(%rdi),%rdi --------------------------------- f: movabs $0x800000000000,%r11 19: cmp %r11,%rdi 1c: jb 0x000000000000002a 1e: mov %rdi,%r11 21: add $0x0,%r11 28: jae 0x000000000000002e 2a: xor %edi,%edi 2c: jmp 0x0000000000000032 2e: mov 0x0(%rdi),%rdi --------------------------------- 32: xor %eax,%eax 34: leave 35: ret The x86-64 JIT already emits some instructions to protect against user memory access.

2024-04-26thermal/debugfs: Prevent use-after-free from occurring after cdev removalRafael J. Wysocki
Since thermal_debug_cdev_remove() does not run under cdev->lock, it can run in parallel with thermal_debug_cdev_state_update() and it may free the struct thermal_debugfs object used by the latter after it has been checked against NULL. If that happens, thermal_debug_cdev_state_update() will access memory that has been freed already causing the kernel to crash. Address this by using cdev->lock in thermal_debug_cdev_remove() around the cdev->debugfs value check (in case the same cdev is removed at the same time in two different threads) and its reset to NULL.

2024-04-26netfs: Fix the pre-flush when appending to a file in writethrough modeDavid Howells
In netfs_perform_write(), when the file is marked NETFS_ICTX_WRITETHROUGH or O_*SYNC or RWF_*SYNC was specified, write-through caching is performed on a buffered file. When setting up for write-through, we flush any conflicting writes in the region and wait for the write to complete, failing if there's a write error to return. The issue arises if we're writing at or above the EOF position because we skip the flush and - more importantly - the wait. This becomes a problem if there's a partial folio at the end of the file that is being written out and we want to make a write to it too. Both the already-running write and the write we start both want to clear the writeback mark, but whoever is second causes a warning looking something like: ------------[ cut here ]------------ R=00000012: folio 11 is not under writeback WARNING: CPU: 34 PID: 654 at fs/netfs/write_collect.c:105 ...

RIP: 0010:netfs_writeback_lookup_folio Fix this by making the flush-and-wait unconditional. It will do nothing if there are no folios in the pagecache and will return quickly if there are no folios in the region specified. Further, move the WBC attachment above the flush call as the flush is going to attach a WBC and detach it again if it is not present - and since we need one anyway we might as well share it.

2024-04-26net l2tp: drop flow hash on forwardDavid Bauer
Drop the flow-hash of the skb when forwarding to the L2TP netdev. This avoids the L2TP qdisc from using the flow-hash from the outer packet, which is identical for every flow within the tunnel. This does not affect every platform but is specific for the ethernet driver. It depends on the platform including L4 information in the flow-hash. One such example is the Mediatek Filogic MT798x family of networking processors.

2024-04-26nsh: Restore skb->{protocol,data,mac_header} for outer header in ↵Kuniyuki Iwashima
nsh_gso_segment(). syzbot triggered various splats (see [0] and links) by a crafted GSO packet of VIRTIO_NET_HDR_GSO_UDP layering the following protocols: ETH_P_8021AD + ETH_P_NSH + ETH_P_IPV6 + IPPROTO_UDP NSH can encapsulate IPv4, IPv6, Ethernet, NSH, and MPLS. As the inner protocol can be Ethernet, NSH GSO handler, nsh_gso_segment(), calls skb_mac_gso_segment() to invoke inner protocol GSO handlers. nsh_gso_segment() does the following for the original skb before calling skb_mac_gso_segment() 1. reset skb->network_header 2. save the original skb->{mac_heaeder,mac_len} in a local variable 3. pull the NSH header 4. resets skb->mac_header 5. set up skb->mac_len and skb->protocol for the inner protocol. and does the following for the segmented skb 6. set ntohs(ETH_P_NSH) to skb->protocol 7. push the NSH header 8. restore skb->mac_header 9. set skb->mac_header + mac_len to skb->network_header 10. restore skb->mac_len There are two problems in 6-7 and 8-9. (a) After 6 & 7, skb->data points to the NSH header, so the outer header (ETH_P_8021AD in this case) is stripped when skb is sent out of netdev. Also, if NSH is encapsulated by NSH + Ethernet (so NSH-Ethernet-NSH), skb_pull() in the first nsh_gso_segment() will make skb->data point to the middle of the outer NSH or Ethernet header because the Ethernet header is not pulled by the second nsh_gso_segment(). (b) While restoring skb->{mac_header,network_header} in 8 & 9, nsh_gso_segment() does not assume that the data in the linear buffer is shifted. However, udp6_ufo_fragment() could shift the data and change skb->mac_header accordingly as demonstrated by syzbot. If this happens, even the restored skb->mac_header points to the middle of the outer header. It seems nsh_gso_segment() has never worked with outer headers so far. At the end of nsh_gso_segment(), the outer header must be restored for the segmented skb, instead of the NSH header. To do that, let's calculate the outer header position relatively from the inner header and set skb->{data,mac_header,protocol} properly.

2024-04-26iommu/amd: Enhance def_domain_type to handle untrusted deviceVasant Hegde
Previously, IOMMU core layer was forcing IOMMU_DOMAIN_DMA domain for untrusted device. This always took precedence over driver's def_domain_type(). Commit 59ddce4418da ("iommu: Reorganize iommu_get_default_domain_type() to respect def_domain_type()") changed the behaviour. Current code calls def_domain_type() but if it doesn't return IOMMU_DOMAIN_DMA for untrusted device it throws error. This results in IOMMU group (and potentially IOMMU itself) in undetermined state. This patch adds untrusted check in AMD IOMMU driver code. So that it allows eGPUs behind Thunderbolt work again. Fine tuning amd_iommu_def_domain_type() will be done later.

2024-04-26hwrng: stm32 - repair clock handlingMarek Vasut
The clock management in this driver does not seem to be correct. The struct hwrng .init callback enables the clock, but there is no matching .cleanup callback to disable the clock. The clock get disabled as some later point by runtime PM suspend callback. Furthermore, both runtime PM and sleep suspend callbacks access registers first and disable clock which are used for register access second. If the IP is already in RPM suspend and the system enters sleep state, the sleep callback will attempt to access registers while the register clock are already disabled. This bug has been fixed once before already in commit 9bae54942b13 ("hwrng: stm32 - fix pm_suspend issue"), and regressed in commit ff4e46104f2e ("hwrng: stm32 - rework power management sequences") . Fix this slightly differently, disable register clock at the end of .init callback, this way the IP is disabled after .init. On every access to the IP, which really is only stm32_rng_read(), do pm_runtime_get_sync() which is already done in stm32_rng_read() to bring the IP from RPM suspend, and pm_runtime_mark_last_busy()/pm_runtime_put_sync_autosuspend() to put it back into RPM suspend. Change sleep suspend/resume callbacks to enable and disable register clock around register access, as those cannot use the RPM suspend/resume callbacks due to slightly different initialization in those sleep callbacks. This way, the register access should always be performed with clock surely enabled.

2024-04-26crypto: ecdh - Initialize ctx->private_key in proper byte orderStefan Berger
The private key in ctx->private_key is currently initialized in reverse byte order in ecdh_set_secret and whenever the key is needed in proper byte order the variable priv is introduced and the bytes from ctx->private_key are copied into priv while being byte-swapped (ecc_swap_digits). To get rid of the unnecessary byte swapping initialize ctx->private_key in proper byte order and clean up all functions that were previously using priv or were called with ctx->private_key: - ecc_gen_privkey: Directly initialize the passed ctx->private_key with random bytes filling all the digits of the private key. Get rid of the priv variable. This function only has ecdh_set_secret as a caller to create NIST P192/256/384 private keys. - crypto_ecdh_shared_secret: Called only from ecdh_compute_value with ctx->private_key. Get rid of the priv variable and work with the passed private_key directly. - ecc_make_pub_key: Called only from ecdh_compute_value with ctx->private_key. Get rid of the priv variable and work with the passed private_key directly.

2024-04-26crypto: ecdh - Pass private key in proper byte order to check valid keyStefan Berger
ecc_is_key_valid expects a key with the most significant digit in the last entry of the digit array. Currently ecdh_set_secret passes a reversed key to ecc_is_key_valid that then passes the rather simple test checking whether the private key is in range [2, n-3]. For all current ecdh- supported curves (NIST P192/256/384) the 'n' parameter is a rather large number, therefore easily passing this test. Throughout the ecdh and ecc codebase the variable 'priv' is used for a private_key holding the bytes in proper byte order. Therefore, introduce priv in ecdh_set_secret and copy the bytes from ctx->private_key into priv in proper byte order by using ecc_swap_digits. Pass priv to ecc_is_valid_key.

2024-04-26crypto: qat - validate slices count returned by FWLucas Segarra Fernandez
The function adf_send_admin_tl_start() enables the telemetry (TL) feature on a QAT device by sending the ICP_QAT_FW_TL_START message to the firmware. This triggers the FW to start writing TL data to a DMA buffer in memory and returns an array containing the number of accelerators of each type (slices) supported by this HW. The pointer to this array is stored in the adf_tl_hw_data data structure called slice_cnt. The array slice_cnt is then used in the function tl_print_dev_data() to report in debugfs only statistics about the supported accelerators. An incorrect value of the elements in slice_cnt might lead to an out of bounds memory read. At the moment, there isn't an implementation of FW that returns a wrong value, but for robustness validate the slice count array returned by FW.
