2025-10-27tools: ynl: avoid print_field when there is no replyHangbin Liu1-0/+3
When request a none support device operation, there will be no reply. In this case, the len(desc) check will always be true, causing print_field to enter an infinite loop and crash the program. Example reproducer: # ethtool.py -c veth0 To fix this, return immediately if there is no reply.

2025-10-27riscv: asm: use .insn for making custom instructionsBen Dooks3-7/+13
The assembler has .insn for building custom instructions now, so change the .4byte to .insn. This ensures the output is marked as an instruction and not as data which may confuse both debuggers and anything else that relies on this sort of marking. Add an ASM_INSN_I() wrapper in asm.h to allow the selecting of how this is output so older assemblers are still good.

2025-10-27tools: ynl: fix string attribute length to include null terminatorPetr Oros1-2/+2
The ynl_attr_put_str() function was not including the null terminator in the attribute length calculation. This caused kernel to reject CTRL_CMD_GETFAMILY requests with EINVAL: "Attribute failed policy validation". For a 4-character family name like "dpll": - Sent: nla_len=8 (4 byte header + 4 byte string without null) - Expected: nla_len=9 (4 byte header + 5 byte string with null) The bug was introduced in commit 15d2540e0d62 ("tools: ynl: check for overflow of constructed messages") when refactoring from stpcpy() to strlen(). The original code correctly included the null terminator: end = stpcpy(ynl_attr_data(attr), str); attr->nla_len = NLA_HDRLEN + NLA_ALIGN(end - (char *)ynl_attr_data(attr)); Since stpcpy() returns a pointer past the null terminator, the length included it. The refactored version using strlen() omitted the +1. The fix also removes NLA_ALIGN() from nla_len calculation, since nla_len should contain actual attribute length, not aligned length. Alignment is only for calculating next attribute position. This makes the code consistent with ynl_attr_put(). CTRL_ATTR_FAMILY_NAME uses NLA_NUL_STRING policy which requires null terminator. Kernel validates with memchr() and rejects if not found.

2025-10-27KMSAN: Restore dynamic check for '-fsanitize=kernel-memory'Nathan Chancellor1-1/+1
Commit 5ff8c11775c7 ("KMSAN: Remove tautological checks") changed CONFIG_HAVE_KMSAN_COMPILER from a dynamic check for '-fsanitize=kernel-memory' to just being true for CONFIG_CC_IS_CLANG. This missed the fact that not all architectures supported '-fsanitize=kernel-memory' at the same time. For example, SystemZ / s390 gained support for KMSAN in clang-18 [1], so builds with clang-15 through clang-17 can select KMSAN but they error with: clang-16: error: unsupported option '-fsanitize=kernel-memory' for target 's390x-unknown-linux-gnu' Restore the cc-option check for '-fsanitize=kernel-memory' to make sure the compiler target properly supports '-fsanitize=kernel-memory'. The check for '-msan-disable-checks=1' does not need to be restored because all supported clang versions for building the kernel support it.

2025-10-27kbuild: align modinfo section for Secureboot Authenticode EDK2 compatDimitri John Ledkov1-1/+1
Previously linker scripts would always generate vmlinuz that has sections aligned. And thus padded (correct Authenticode calculation) and unpadded calculation would be same. As in https://github.com/rhboot/pesign userspace tool would produce the same authenticode digest for both of the following commands: pesign --padding --hash --in ./arch/x86_64/boot/bzImage pesign --nopadding --hash --in ./arch/x86_64/boot/bzImage The commit 3e86e4d74c04 ("kbuild: keep .modinfo section in vmlinux.unstripped") added .modinfo section of variable length. Depending on kernel configuration it may or may not be aligned. All userspace signing tooling correctly pads such section to calculation spec compliant authenticode digest. However, if bzImage is not further processed and is attempted to be loaded directly by EDK2 firmware, it calculates unpadded Authenticode digest and fails to correct accept/reject such kernel builds even when propoer Authenticode values are enrolled in db/dbx. One can say EDK2 requires aligned/padded kernels in Secureboot. Thus add ALIGN(8) to the .modinfo section, to esure kernels irrespective of modinfo contents can be loaded by all existing EDK2 firmware builds.

2025-10-27drm/etnaviv: fix flush sequence logicTomeu Vizoso1-1/+1
The current logic uses the flush sequence from the current address space. This is harmless when deducing the flush requirements for the current submit, as either the incoming address space is the same one as the currently active one or we switch context, in which case the flush is unconditional. However, this sequence is also stored as the current flush sequence of the GPU. If we switch context the stored flush sequence will no longer belong to the currently active address space. This incoherency can then cause missed flushes, resulting in translation errors.

2025-10-27riscv: Fix memory leak in module_frob_arch_sections()Miaoqian Lin1-2/+6
The current code directly overwrites the scratch pointer with the return value of kvrealloc(). If kvrealloc() fails and returns NULL, the original buffer becomes unreachable, causing a memory leak.

2025-10-27riscv: ptdump: use seq_puts() in pt_dump_seq_puts() macroJosephine Pfeiffer1-1/+1
The pt_dump_seq_puts() macro incorrectly uses seq_printf() instead of seq_puts(). This is both a performance issue and conceptually wrong, as the macro name suggests plain string output (puts) but the implementation uses formatted output (printf). The macro is used in ptdump.c:301 to output a newline character. Using seq_printf() adds unnecessary overhead for format string parsing when outputting this constant string. This bug was introduced in commit 59c4da8640cc ("riscv: Add support to dump the kernel page tables") in 2020, which copied the implementation pattern from other architectures that had the same bug.

2025-10-27kunit: prevent log overwrite in param_testsCarlos Llamas1-1/+2
When running parameterized tests, each test case is initialized with kunit_init_test(). This function takes the test_case->log as a parameter but it clears it via string_stream_clear() on each iteration. This results in only the log from the last parameter being preserved in the test_case->log and the results from the previous parameters are lost from the debugfs entry. Fix this by manually setting the param_test.log to the test_case->log after it has been initialized. This prevents kunit_init_test() from clearing the log on each iteration.

A throughput regression of 11% introduced by commit 779b1a1cb13a ("cpuidle: governors: menu: Avoid selecting states with too much latency") has been reported and it is related to the case when the menu governor checks if selecting a proper idle state instead of a polling one makes sense.

smb_direct_disconnect_rdma_work() All handlers triggered by ib_drain_qp() should already see the broken connection. smb_direct_cm_handler() is called under a mutex of the rdma_cm, we should make sure ib_drain_qp() and all rdma layer logic completes and unlocks the mutex. It means free_transport() will also already see the connection as SMBDIRECT_SOCKET_DISCONNECTED, so we need to call crdma_[un]lock_handler(sc->rdma.cm_id) around ib_drain_qp(), rdma_destroy_qp(), ib_free_cq() and ib_dealloc_pd(). Otherwise we free resources while the ib_drain_qp() within smb_direct_cm_handler() is still running. We have to unlock before rdma_destroy_id() as it locks again.

We now activate sc->recv_io.posted.refill_work and sc->idle.immediate_work only after a successful negotiation, before sending the negotiation response. It means the queue_work(sc->workqueue, &sc->recv_io.posted.refill_work) in put_recvmsg() of the negotiate request, is a no-op now. It also means our explicit smb_direct_post_recv_credits() will have queue_work(sc->workqueue, &sc->idle.immediate_work) as no-op. This should make sure we don't have races and post any immediate data_transfer message that tries to grant credits to the peer, before we send the negotiation response, as that will grant the initial credits to the peer.

While the DP83867 PHYs report EEE capability through their feature registers, the actual hardware does not support EEE (see Links). When the connected MAC enables EEE, it causes link instability and communication failures. The issue is reproducible with a iMX8MP and relevant stmmac ethernet port. Since the introduction of phylink-managed EEE support in the stmmac driver, EEE is now enabled by default, leading to issues on systems using the DP83867 PHY. Call phy_disable_eee during phy initialization to prevent EEE from being enabled on DP83867 PHYs.

2025-10-24Bluetooth: rfcomm: fix modem control handlingJohan Hovold1-15/+11
The RFCOMM driver confuses the local and remote modem control signals, which specifically means that the reported DTR and RTS state will instead reflect the remote end (i.e. DSR and CTS). This issue dates back to the original driver (and a follow-on update) merged in 2002, which resulted in a non-standard implementation of TIOCMSET that allowed controlling also the TS07.10 IC and DV signals by mapping them to the RI and DCD input flags, while TIOCMGET failed to return the actual state of DTR and RTS. Note that the bogus control of input signals in tiocmset() is just dead code as those flags will have been masked out by the tty layer since 2003.

2025-10-24Bluetooth: fix corruption in h4_recv_buf() after cleanupCalvin Owens14-19/+25
A different structure is stored in drvdata for the drivers which used that duplicate function, but h4_recv_buf() assumes drvdata is always an hci_uart structure. Consequently, alignment and padding are now randomly corrupted for btmtkuart, btnxpuart, and bpa10x in h4_recv_buf(), causing erratic breakage. Fix this by making the hci_uart structure the explicit argument to h4_recv_buf(). Every caller already has a reference to hci_uart, and already obtains the hci_hdev reference through it, so this actually eliminates a redundant pointer indirection for all existing callers.

2025-10-24Bluetooth: btintel_pcie: Fix event packet loss issueKiran K1-5/+6
In the current btintel_pcie driver implementation, when an interrupt is received, the driver checks for the alive cause before the TX/RX cause. Handling the alive cause involves resetting the TX/RX queue indices. This flow works correctly when the causes are mutually exclusive. However, if both cause bits are set simultaneously, the alive cause resets the queue indices, resulting in an event packet drop and a command timeout. To fix this issue, the driver is modified to handle all other causes before checking for the alive cause.
