2025-04-11iommu: Fix crash in report_iommu_fault()Fedor Pchelkin
The following crash is observed while handling an IOMMU fault with a recent kernel: kernel tried to execute NX-protected page - exploit attempt? (uid: 0) BUG: unable to handle page fault for address: ffff8c708299f700 PGD 19ee01067 P4D 19ee01067 PUD 101c10063 PMD 80000001028001e3 Oops: Oops: 0011 [#1] SMP NOPTI CPU: 4 UID: 0 PID: 139 Comm: irq/25-AMD-Vi Not tainted 6.15.0-rc1+ #20 PREEMPT(lazy) Hardware name: LENOVO 21D0/LNVNB161216, BIOS J6CN50WW 09/27/2024 RIP: 0010:0xffff8c708299f700 Call Trace: <TASK> ? report_iommu_fault+0x78/0xd3 ? amd_iommu_report_page_fault+0x91/0x150 ? amd_iommu_int_thread+0x77/0x180 ? __pfx_irq_thread_fn+0x10/0x10 ? irq_thread_fn+0x23/0x60 ? irq_thread+0xf9/0x1e0 ? __pfx_irq_thread_dtor+0x10/0x10 ? __pfx_irq_thread+0x10/0x10 ? kthread+0xfc/0x240 ? __pfx_kthread+0x10/0x10 ? ret_from_fork+0x34/0x50 ? __pfx_kthread+0x10/0x10 ? ret_from_fork_asm+0x1a/0x30 </TASK> report_iommu_fault() checks for an installed handler comparing the corresponding field to NULL. It can (and could before) be called for a domain with a different cookie type - IOMMU_COOKIE_DMA_IOVA, specifically. Cookie is represented as a union so we may end up with a garbage value treated there if this happens for a domain with another cookie type. Formerly there were two exclusive cookie types in the union. IOMMU_DOMAIN_SVA has a dedicated iommu_report_device_fault(). Call the fault handler only if the passed domain has a required cookie type.

2025-04-10bpf: Convert queue_stack map to rqspinlockKumar Kartikeya Dwivedi
Replace all usage of raw_spinlock_t in queue_stack_maps.c with rqspinlock. This is a map type with a set of open syzbot reports reproducing possible deadlocks. Prior attempt to fix the issues was at [0], but was dropped in favor of this approach. Make sure we return the -EBUSY error in case of possible deadlocks or timeouts, just to make sure user space or BPF programs relying on the error code to detect problems do not break. With these changes, the map should be safe to access in any context, including NMIs.

2025-04-10bpf: Use architecture provided res_smp_cond_load_acquireKumar Kartikeya Dwivedi
In v2 of rqspinlock [0], we fixed potential problems with WFE usage in arm64 to fallback to a version copied from Ankur's series [1]. This logic was moved into arch-specific headers in v3 [2]. However, we missed using the arch-provided res_smp_cond_load_acquire in commit ebababcd0372 ("rqspinlock: Hardcode cond_acquire loops for arm64") due to a rebasing mistake between v2 and v3 of the rqspinlock series. Fix the typo to fallback to the arm64 definition as we did in v2.

2025-04-10ext4: don't treat fhandle lookup of ea_inode as FS corruptionJann Horn
A file handle that userspace provides to open_by_handle_at() can legitimately contain an outdated inode number that has since been reused for another purpose - that's why the file handle also contains a generation number. But if the inode number has been reused for an ea_inode, check_igot_inode() will notice, __ext4_iget() will go through ext4_error_inode(), and if the inode was newly created, it will also be marked as bad by iget_failed(). This all happens before the point where the inode generation is checked. ext4_error_inode() is supposed to only be used on filesystem corruption; it should not be used when userspace just got unlucky with a stale file handle. So when this happens, let __ext4_iget() just return an error.

2025-04-10ethtool: cmis_cdb: Fix incorrect read / write length extensionIdo Schimmel
The 'read_write_len_ext' field in 'struct ethtool_cmis_cdb_cmd_args' stores the maximum number of bytes that can be read from or written to the Local Payload (LPL) page in a single multi-byte access. Cited commit started overwriting this field with the maximum number of bytes that can be read from or written to the Extended Payload (LPL) pages in a single multi-byte access. Transceiver modules that support auto paging can advertise a number larger than 255 which is problematic as 'read_write_len_ext' is a 'u8', resulting in the number getting truncated and firmware flashing failing [1]. Fix by ignoring the maximum EPL access size as the kernel does not currently support auto paging (even if the transceiver module does) and will not try to read / write more than 128 bytes at once. [1] Transceiver module firmware flashing started for device enp177s0np0 Transceiver module firmware flashing in progress for device enp177s0np0 Progress: 0% Transceiver module firmware flashing encountered an error for device enp177s0np0 Status message: Write FW block EPL command failed, LPL length is longer than CDB read write length extension allows.

Commit 40369bfe717e ("spi: fsl-qspi: use devm function instead of driver remove") introduced managed cleanup via fsl_qspi_cleanup(), but incorrectly retain manual cleanup in two scenarios: - On devm_add_action_or_reset() failure, the function automatically call fsl_qspi_cleanup(). However, the current code still jumps to err_destroy_mutex, repeating cleanup. - After the fsl_qspi_cleanup() action is added successfully, there is no need to manually perform the cleanup in the subsequent error path. However, the current code still jumps to err_destroy_mutex on spi controller failure, repeating cleanup. Skip redundant manual cleanup calls to fix these issues.

Given a set element like: icmpv6 . dead:beef:00ff::1 The value of 'ff' is irrelevant, any address will be matched as long as the other octets are the same. This is because of too-early register clobbering: ymm7 is reloaded with new packet data (pkt[9]) but it still holds data of an earlier load that wasn't processed yet. The existing tests in nft_concat_range.sh selftests do exercise this code path, but do not trigger incorrect matching due to the network prefix limitation.

Willem de Bruijn says: ==================== support SKF_NET_OFF and SKF_LL_OFF on skb frags From: Willem de Bruijn <willemb@google.com> Address a longstanding issue that may lead to missed packets depending on system configuration. Ensure that reading from packet contents works regardless of skb geometry, also when using the special SKF_.. negative offsets to offset from L2 or L3 header. Patch 2 is the selftest for the fix. v2->v3 - do not remove bpf_internal_load_pointer_neg_helper, because it is still used in the sparc32 JIT v1->v2 - introduce bfp_skb_load_helper_convert_offset to avoid open coding - selftest: add comment why early demux must be disabled v2: https://lore.kernel.org/netdev/20250404142633.1955847-1-willemdebruijn.kernel@gmail.com/ v1: https://lore.kernel.org/netdev/20250403140846.1268564-1-willemdebruijn.kernel@gmail.com/ ==================== Link: https://patch.msgid.link/20250408132833.195491-1-willemdebruijn.kernel@gmail.com Signed-off-by: Alexei Starovoitov <ast@kernel.org>
2025-04-09selftests/net: test sk_filter support for SKF_NET_OFF on fragsWillem de Bruijn
Verify that a classic BPF linux socket filter correctly matches packet contents. Including when accessing contents in an skb_frag. 1. Open a SOCK_RAW socket with a classic BPF filter on UDP dport 8000. 2. Open a tap device with IFF_NAPI_FRAGS to inject skbs with frags. 3. Send a packet for which the UDP header is in frag[0]. 4. Receive this packet to demonstrate that the socket accepted it.
