[PATCH v3] svc-i3c-master: Fix read from unreadable memory at svc_i3c_master_ibi_work

by Manjunatha Venkatesh

As part of I3C driver probing sequence for particular device instance, While adding to queue it is trying to access ibi variable of dev which is not yet initialized causing "Unable to handle kernel read from unreadable memory" resulting in kernel panic. Below is the sequence where this issue happened. 1. During boot up sequence IBI is received at host from the slave device before requesting for IBI, Usually will request IBI by calling i3c_device_request_ibi() during probe of slave driver. 2. Since master code trying to access IBI Variable for the particular device instance before actually it initialized by slave driver, due to this randomly accessing the address and causing kernel panic. 3. i3c_device_request_ibi() function invoked by the slave driver where dev->ibi = ibi; assigned as part of function call i3c_dev_request_ibi_locked(). 4. But when IBI request sent by slave device, master code trying to access this variable before its initialized due to this race condition situation kernel panic happened. fixes: dd3c52846d595 (i3c: master: svc: Add Silvaco I3C master driver) Cc: stable(a)vger.kernel.org Signed-off-by: Manjunatha Venkatesh <manjunatha.venkatesh(a)nxp.com> --- Changes since v2: - Description updated as per the review feedback drivers/i3c/master/svc-i3c-master.c | 7 +++++-- 1 file changed, 5 insertions(+), 2 deletions(-) diff --git a/drivers/i3c/master/svc-i3c-master.c b/drivers/i3c/master/svc-i3c-master.c index d6057d8c7dec..98c4d2e5cd8d 100644 --- a/drivers/i3c/master/svc-i3c-master.c +++ b/drivers/i3c/master/svc-i3c-master.c @@ -534,8 +534,11 @@ static void svc_i3c_master_ibi_work(struct work_struct *work) switch (ibitype) { case SVC_I3C_MSTATUS_IBITYPE_IBI: if (dev) { - i3c_master_queue_ibi(dev, master->ibi.tbq_slot); - master->ibi.tbq_slot = NULL; + data = i3c_dev_get_master_data(dev); + if (master->ibi.slots[data->ibi]) { + i3c_master_queue_ibi(dev, master->ibi.tbq_slot); + master->ibi.tbq_slot = NULL; + } } svc_i3c_master_emit_stop(master); break; -- 2.46.1

[PATCH 1/3] mm/memblock: pass size instead of end to memblock_set_node()

by Wei Yang

The second parameter of memblock_set_node() is size instead of end. Since it iterates from lower address to higher address, finally the node id is correct.

[PATCH v4 0/4] samsung: pinctrl: Add support for eint_fltcon_offset and filter selection on gs101

by Peter Griffin

Hi folks, This series fixes support for correctly saving and restoring fltcon0 and fltcon1 registers on gs101 for non-alive banks where the fltcon register offset is not at a fixed offset (unlike previous SoCs). This is done by adding a eint_fltcon_offset and providing GS101 specific pin macros that take an additional parameter (similar to how exynosautov920 handles it's eint_con_offset). Additionally the SoC specific suspend and resume callbacks are re-factored so that each SoC variant has it's own callback containing the peculiarities for that SoC. Finally support for filter selection on alive banks is added, this is currently only enabled for gs101.

[PATCH v3 0/6] KVM: arm64: PMU: Fix SET_ONE_REG for vPMC regs

by Akihiko Odaki

Prepare vPMC registers for user-initiated changes after first run. This is important specifically for debugging Windows on QEMU with GDB; QEMU tries to write back all visible registers when resuming the VM execution with GDB, corrupting the PMU state. Windows always uses the PMU so this can cause adverse effects on that particular OS. This series also contains patch "KVM: arm64: PMU: Set raw values from user to PM{C,I}NTEN{SET,CLR}, PMOVS{SET,CLR}", which reverts semantic changes made for the mentioned registers in the past. It is necessary to migrate the PMU state properly on Firecracker, QEMU, and crosvm. Signed-off-by: Akihiko Odaki <akihiko.odaki(a)daynix.com> --- Changes in v3: - Added patch "KVM: arm64: PMU: Assume PMU presence in pmu-emul.c". - Added an explanation of this path series' motivation to each patch. - Explained why userspace register writes and register reset should be covered in patch "KVM: arm64: PMU: Reload when user modifies registers". - Marked patch "KVM: arm64: PMU: Set raw values from user to PM{C,I}NTEN{SET,CLR}, PMOVS{SET,CLR}" for stable. - Reoreded so that patch "KVM: arm64: PMU: Set raw values from user to PM{C,I}NTEN{SET,CLR}, PMOVS{SET,CLR}" would come first. - Added patch "KVM: arm64: PMU: Call kvm_pmu_handle_pmcr() after masking PMCNTENSET_EL0". - Added patch "KVM: arm64: Reload PMCNTENSET_EL0". - Link to v2: https://lore.kernel.org/r/20250307-pmc-v2-0-6c3375a5f1e4@daynix.com Changes in v2: - Changed to utilize KVM_REQ_RELOAD_PMU as suggested by Oliver Upton. - Added patch "KVM: arm64: PMU: Reload when user modifies registers" to cover more registers. - Added patch "KVM: arm64: PMU: Set raw values from user to PM{C,I}NTEN{SET,CLR}, PMOVS{SET,CLR}". - Link to v1: https://lore.kernel.org/r/20250302-pmc-v1-1-caff989093dc@daynix.com --- Akihiko Odaki (6): KVM: arm64: PMU: Set raw values from user to PM{C,I}NTEN{SET,CLR}, PMOVS{SET,CLR} KVM: arm64: PMU: Assume PMU presence in pmu-emul.c KVM: arm64: PMU: Fix SET_ONE_REG for vPMC regs KVM: arm64: PMU: Reload when user modifies registers KVM: arm64: PMU: Call kvm_pmu_handle_pmcr() after masking PMCNTENSET_EL0 KVM: arm64: Reload PMCNTENSET_EL0 arch/arm64/kvm/arm.c | 8 ++++--- arch/arm64/kvm/guest.c | 12 +++++++++++ arch/arm64/kvm/pmu-emul.c | 54 ++++++++++++++++------------------------------- arch/arm64/kvm/sys_regs.c | 53 ++++++++++++++++++++++++++-------------------- include/kvm/arm_pmu.h | 1 + 5 files changed, 66 insertions(+), 62 deletions(-) --- base-commit: da2f480cb24d39d480b1e235eda0dd2d01f8765b change-id: 20250302-pmc-b90a86af945c Best regards, -- Akihiko Odaki <akihiko.odaki(a)daynix.com>

[PATCH] usb: typec: tcpm: fix state transition for SNK_WAIT_CAPABILITIES state in run_state_machine()

by Amit Sunil Dhamne via B4 Relay

From: Amit Sunil Dhamne <amitsd(a)google.com> A subtle error got introduced while manually fixing merge conflict in tcpm.c for commit 85c4efbe6088 ("Merge v6.12-rc6 into usb-next"). As a result of this error, the next state is unconditionally set to SNK_WAIT_CAPABILITIES_TIMEOUT while handling SNK_WAIT_CAPABILITIES state in run_state_machine(...). Fix this by setting new state of TCPM state machine to `upcoming_state` (that is set to different values based on conditions).

[PATCH v3 0/7] drm/v3d: Fix GPU reset issues on the Raspberry Pi 5

by Maíra Canal

This series addresses GPU reset issues reported in [1], where running a long compute job would trigger repeated GPU resets, leading to a UI freeze. Patches #1 and #2 prevent the same faulty job from being resubmitted in a loop, mitigating the first cause of the issue. However, the issue isn't entirely solved. Even with only a single GPU reset, the UI still freezes on the Raspberry Pi 5, indicating a GPU hang. Patches #3 to #6 address this by properly configuring the V3D_SMS registers, which are required for power management and resets in V3D 7.1. Patch #7 updates the DT maintainership, replacing Emma with the current v3d driver maintainer.

[PATCH v5 01/16] x86/stackprotector: Work around strict Clang TLS symbol requirements

by Brian Gerst

From: Ard Biesheuvel <ardb(a)kernel.org> GCC and Clang both implement stack protector support based on Thread Local Storage (TLS) variables, and this is used in the kernel to implement per-task stack cookies, by copying a task's stack cookie into a per-CPU variable every time it is scheduled in. Both now also implement -mstack-protector-guard-symbol=, which permits the TLS variable to be specified directly. This is useful because it will allow us to move away from using a fixed offset of 40 bytes into the per-CPU area on x86_64, which requires a lot of special handling in the per-CPU code and the runtime relocation code. However, while GCC is rather lax in its implementation of this command line option, Clang actually requires that the provided symbol name refers to a TLS variable (i.e., one declared with __thread), although it also permits the variable to be undeclared entirely, in which case it will use an implicit declaration of the right type. The upshot of this is that Clang will emit the correct references to the stack cookie variable in most cases, e.g., 10d: 64 a1 00 00 00 00 mov %fs:0x0,%eax 10f: R_386_32 __stack_chk_guard However, if a non-TLS definition of the symbol in question is visible in the same compilation unit (which amounts to the whole of vmlinux if LTO is enabled), it will drop the per-CPU prefix and emit a load from a bogus address. Work around this by using a symbol name that never occurs in C code, and emit it as an alias in the linker script.
