[PATCH 6.1.y] thunderbolt: Fix Thunderbolt 3 display flickering issue on 2nd hot plug onwards

by Mario Limonciello

From: Sanjay R Mehta <sanju.mehta(a)amd.com> Previously, on unplug events, the TMU mode was disabled first followed by the Time Synchronization Handshake, irrespective of whether the tb_switch_tmu_rate_write() API was successful or not. However, this caused a problem with Thunderbolt 3 (TBT3) devices, as the TSPacketInterval bits were always enabled by default, leading the host router to assume that the device router's TMU was already enabled and preventing it from initiating the Time Synchronization Handshake. As a result, TBT3 monitors experienced display flickering from the second hot plug onwards. To address this issue, we have modified the code to only disable the Time Synchronization Handshake during TMU disable if the tb_switch_tmu_rate_write() function is successful. This ensures that the TBT3 devices function correctly and eliminates the display flickering issue.

[PATCH AUTOSEL 5.15 1/6] idmaengine: make FSL_EDMA and INTEL_IDMA64 depends on HAS_IOMEM

by Sasha Levin

From: Baoquan He <bhe(a)redhat.com> [ Upstream commit b1e213a9e31c20206f111ec664afcf31cbfe0dbb ] On s390 systems (aka mainframes), it has classic channel devices for networking and permanent storage that are currently even more common than PCI devices. Hence it could have a fully functional s390 kernel with CONFIG_PCI=n, then the relevant iomem mapping functions [including ioremap(), devm_ioremap(), etc.] are not available. Here let FSL_EDMA and INTEL_IDMA64 depend on HAS_IOMEM so that it won't be built to cause below compiling error if PCI is unset. -------- ERROR: modpost: "devm_platform_ioremap_resource" [drivers/dma/fsl-edma.ko] undefined!

[PATCH] drm/vmwgfx: Fix possible invalid drm gem put calls

by Zack Rusin

From: Zack Rusin <zackr(a)vmware.com> vmw_bo_unreference sets the input buffer to null on exit, resulting in null ptr deref's on the subsequent drm gem put calls. This went unnoticed because only very old userspace would be exercising those paths but it wouldn't be hard to hit on old distros with brand new kernels. Introduce a new function that abstracts unrefing of user bo's to make the code cleaner and more explicit. Signed-off-by: Zack Rusin <zackr(a)vmware.com> Reported-by: Ian Forbes <iforbes(a)vmware.com> Fixes: 9ef8d83e8e25 ("drm/vmwgfx: Do not drop the reference to the handle too soon") Cc: <stable(a)vger.kernel.org> # v6.4+ --- drivers/gpu/drm/vmwgfx/vmwgfx_bo.c | 6 ++---- drivers/gpu/drm/vmwgfx/vmwgfx_bo.h | 8 ++++++++ drivers/gpu/drm/vmwgfx/vmwgfx_execbuf.c | 6 ++---- drivers/gpu/drm/vmwgfx/vmwgfx_kms.c | 6 ++---- drivers/gpu/drm/vmwgfx/vmwgfx_overlay.c | 3 +-- drivers/gpu/drm/vmwgfx/vmwgfx_shader.c | 3 +-- 6 files changed, 16 insertions(+), 16 deletions(-) diff --git a/drivers/gpu/drm/vmwgfx/vmwgfx_bo.c b/drivers/gpu/drm/vmwgfx/vmwgfx_bo.c index 82094c137855..c43853597776 100644 --- a/drivers/gpu/drm/vmwgfx/vmwgfx_bo.c +++ b/drivers/gpu/drm/vmwgfx/vmwgfx_bo.c @@ -497,10 +497,9 @@ static int vmw_user_bo_synccpu_release(struct drm_file *filp, if (!(flags & drm_vmw_synccpu_allow_cs)) { atomic_dec(&vmw_bo->cpu_writers); } - ttm_bo_put(&vmw_bo->tbo); + vmw_user_bo_unref(vmw_bo); } - drm_gem_object_put(&vmw_bo->tbo.base); return ret; } @@ -540,8 +539,7 @@ int vmw_user_bo_synccpu_ioctl(struct drm_device *dev, void *data, return ret; ret = vmw_user_bo_synccpu_grab(vbo, arg->flags); - vmw_bo_unreference(&vbo); - drm_gem_object_put(&vbo->tbo.base); + vmw_user_bo_unref(vbo); if (unlikely(ret != 0)) { if (ret == -ERESTARTSYS || ret == -EBUSY) return -EBUSY; diff --git a/drivers/gpu/drm/vmwgfx/vmwgfx_bo.h b/drivers/gpu/drm/vmwgfx/vmwgfx_bo.h index 50a836e70994..1d433fceed3d 100644 --- a/drivers/gpu/drm/vmwgfx/vmwgfx_bo.h +++ b/drivers/gpu/drm/vmwgfx/vmwgfx_bo.h @@ -195,6 +195,14 @@ static inline struct vmw_bo *vmw_bo_reference(struct vmw_bo *buf) return buf; } +static inline void vmw_user_bo_unref(struct vmw_bo *vbo) +{ + if (vbo) { + ttm_bo_put(&vbo->tbo); + drm_gem_object_put(&vbo->tbo.base); + } +} + static inline struct vmw_bo *to_vmw_bo(struct drm_gem_object *gobj) { return container_of((gobj), struct vmw_bo, tbo.base); diff --git a/drivers/gpu/drm/vmwgfx/vmwgfx_execbuf.c b/drivers/gpu/drm/vmwgfx/vmwgfx_execbuf.c index 6b9aa2b4ef54..25b96821df0f 100644 --- a/drivers/gpu/drm/vmwgfx/vmwgfx_execbuf.c +++ b/drivers/gpu/drm/vmwgfx/vmwgfx_execbuf.c @@ -1164,8 +1164,7 @@ static int vmw_translate_mob_ptr(struct vmw_private *dev_priv, } vmw_bo_placement_set(vmw_bo, VMW_BO_DOMAIN_MOB, VMW_BO_DOMAIN_MOB); ret = vmw_validation_add_bo(sw_context->ctx, vmw_bo); - ttm_bo_put(&vmw_bo->tbo); - drm_gem_object_put(&vmw_bo->tbo.base); + vmw_user_bo_unref(vmw_bo); if (unlikely(ret != 0)) return ret; @@ -1221,8 +1220,7 @@ static int vmw_translate_guest_ptr(struct vmw_private *dev_priv, vmw_bo_placement_set(vmw_bo, VMW_BO_DOMAIN_GMR | VMW_BO_DOMAIN_VRAM, VMW_BO_DOMAIN_GMR | VMW_BO_DOMAIN_VRAM); ret = vmw_validation_add_bo(sw_context->ctx, vmw_bo); - ttm_bo_put(&vmw_bo->tbo); - drm_gem_object_put(&vmw_bo->tbo.base); + vmw_user_bo_unref(vmw_bo); if (unlikely(ret != 0)) return ret; diff --git a/drivers/gpu/drm/vmwgfx/vmwgfx_kms.c b/drivers/gpu/drm/vmwgfx/vmwgfx_kms.c index b62207be3363..1489ad73c103 100644 --- a/drivers/gpu/drm/vmwgfx/vmwgfx_kms.c +++ b/drivers/gpu/drm/vmwgfx/vmwgfx_kms.c @@ -1665,10 +1665,8 @@ static struct drm_framebuffer *vmw_kms_fb_create(struct drm_device *dev, err_out: /* vmw_user_lookup_handle takes one ref so does new_fb */ - if (bo) { - vmw_bo_unreference(&bo); - drm_gem_object_put(&bo->tbo.base); - } + if (bo) + vmw_user_bo_unref(bo); if (surface) vmw_surface_unreference(&surface); diff --git a/drivers/gpu/drm/vmwgfx/vmwgfx_overlay.c b/drivers/gpu/drm/vmwgfx/vmwgfx_overlay.c index 7e112319a23c..fb85f244c3d0 100644 --- a/drivers/gpu/drm/vmwgfx/vmwgfx_overlay.c +++ b/drivers/gpu/drm/vmwgfx/vmwgfx_overlay.c @@ -451,8 +451,7 @@ int vmw_overlay_ioctl(struct drm_device *dev, void *data, ret = vmw_overlay_update_stream(dev_priv, buf, arg, true); - vmw_bo_unreference(&buf); - drm_gem_object_put(&buf->tbo.base); + vmw_user_bo_unref(buf); out_unlock: mutex_unlock(&overlay->mutex); diff --git a/drivers/gpu/drm/vmwgfx/vmwgfx_shader.c b/drivers/gpu/drm/vmwgfx/vmwgfx_shader.c index e7226db8b242..1e81ff2422cf 100644 --- a/drivers/gpu/drm/vmwgfx/vmwgfx_shader.c +++ b/drivers/gpu/drm/vmwgfx/vmwgfx_shader.c @@ -809,8 +809,7 @@ static int vmw_shader_define(struct drm_device *dev, struct drm_file *file_priv, shader_type, num_input_sig, num_output_sig, tfile, shader_handle); out_bad_arg: - vmw_bo_unreference(&buffer); - drm_gem_object_put(&buffer->tbo.base); + vmw_user_bo_unref(buffer); return ret; } -- 2.39.2

[PATCH 15/21] drm/amd/display: Remove wait while locked

by Hamza Mahfooz

From: Gabe Teeger <gabe.teeger(a)amd.com> [Why] We wait for mpc idle while in a locked state, leading to potential deadlock. [What] Move the wait_for_idle call to outside of HW lock. This and a call to wait_drr_doublebuffer_pending_clear are moved added to a new static helper function called wait_for_outstanding_hw_updates, to make the interface clearer.

[PATCH 04/21] drm/amd/display: update blank state on ODM changes

by Hamza Mahfooz

From: Wenjing Liu <wenjing.liu(a)amd.com> When we are dynamically adding new ODM slices, we didn't update blank state, if the pipe used by new ODM slice is previously blanked, we will continue outputting blank pixel data on that slice causing right half of the screen showing blank image.

[PATCH v2 0/2] ath11k: Don't leak ack_status_frame during tx_complete* processing

by Sven Eckelmann

It was noticed that APs stopped to accept clients after a while. With QCA's ath11k fork, it even printed some additional information: attach ack fail -28 when new clients tried to connect. hostapd was then usually showing a message like "deauthenticated due to inactivity (timer DEAUTH/REMOVE)". While debugging this, it was noticed that this happened when a peer was no longer known by ath11k but an NL80211_CMD_PROBE_CLIENT triggered TX was just "finished" for it. In that case, ath11k was just throwing the skb away and left some information in various data structures in mac80211. And after Felix pointed out ieee80211_free_txskb(), it is also clear that dev_kfree_skb_any() in these functions should also be calls to ieee80211_free_txskb() - but for these, I have nothing to trigger this error case. Still, a patch is provided as part of this patch series.

[PATCH v5] riscv: Handle zicsr/zifencei issue between gcc and binutils

by Mingzheng Xing

Binutils-2.38 and GCC-12.1.0 bumped[0][1] the default ISA spec to the newer 20191213 version which moves some instructions from the I extension to the Zicsr and Zifencei extensions. So if one of the binutils and GCC exceeds that version, we should explicitly specifying Zicsr and Zifencei via -march to cope with the new changes. but this only occurs when binutils >= 2.36 and GCC >= 11.1.0. It's a different story when binutils < 2.36. binutils-2.36 supports the Zifencei extension[2] and splits Zifencei and Zicsr from I[3]. GCC-11.1.0 is particular[4] because it add support Zicsr and Zifencei extension for -march. binutils-2.35 does not support the Zifencei extension, and does not need to specify Zicsr and Zifencei when working with GCC >= 12.1.0. To make our lives easier, let's relax the check to binutils >= 2.36 in CONFIG_TOOLCHAIN_NEEDS_EXPLICIT_ZICSR_ZIFENCEI. For the other two cases, where clang < 17 or GCC < 11.1.0, we will deal with them in CONFIG_TOOLCHAIN_NEEDS_OLD_ISA_SPEC. For more information, please refer to: commit 6df2a016c0c8 ("riscv: fix build with binutils 2.38") commit e89c2e815e76 ("riscv: Handle zicsr/zifencei issues between clang and binutils") Link: https://sourceware.org/git/?p=binutils-gdb.git;a=commit;h=aed44286efa8ae871… [0] Link: https://gcc.gnu.org/git/?p=gcc.git;a=commit;h=98416dbb0a62579d4a7a4a76bab51… [1] Link: https://sourceware.org/git/?p=binutils-gdb.git;a=commit;h=5a1b31e1e1cee6e9f… [2] Link: https://sourceware.org/git/?p=binutils-gdb.git;a=commit;h=729a53530e86972d1… [3] Link: https://gcc.gnu.org/git/?p=gcc.git;a=commit;h=b03be74bad08c382da47e048007a7… [4] Link: https://lore.kernel.org/all/20230308220842.1231003-1-conor@kernel.org Link: https://lore.kernel.org/all/20230223220546.52879-1-conor@kernel.org Reviewed-by: Conor Dooley <conor.dooley(a)microchip.com> Acked-by: Guo Ren <guoren(a)kernel.org> Cc: <stable(a)vger.kernel.org> Signed-off-by: Mingzheng Xing <xingmingzheng(a)iscas.ac.cn> --- Changelog and test results: v4 -> v5: - Add Reviewed-by and Acked-by to commit message, no other code changes. v3 -> v4: - Update the Kconfig help text and commit message.

[PATCH v2] usb: typec: tcpm: set initial svdm version based on pd revision

by RD Babiera

When sending Discover Identity messages to a Port Partner that uses Power Delivery v2 and SVDM v1, we currently send PD v2 messages with SVDM v2.0, expecting the port partner to respond with its highest supported SVDM version as stated in Section 6.4.4.2.3 in the Power Delivery v3 specification. However, sending SVDM v2 to some Power Delivery v2 port partners results in a NAK whereas sending SVDM v1 does not. NAK messages can be handled by the initiator (PD v3 section 6.4.4.2.5.1), and one solution could be to resend Discover Identity on a lower SVDM version if possible. But, Section 6.4.4.3 of PD v2 states that "A NAK response Should be taken as an indication not to retry that particular Command." Instead, we can set the SVDM version to the maximum one supported by the negotiated PD revision. When operating in PD v2, this obeys Section 6.4.4.2.3, which states the SVDM field "Shall be set to zero to indicate Version 1.0." In PD v3, the SVDM field "Shall be set to 01b to indicate Version 2.0."

[PATCH v2 bpf-next 1/2] bpf: Fix issue in verifying allow_ptr_leaks

by Yafang Shao

After we converted the capabilities of our networking-bpf program from cap_sys_admin to cap_net_admin+cap_bpf, our networking-bpf program failed to start. Because it failed the bpf verifier, and the error log is "R3 pointer comparison prohibited". A simple reproducer as follows, SEC("cls-ingress") int ingress(struct __sk_buff *skb) { struct iphdr *iph = (void *)(long)skb->data + sizeof(struct ethhdr); if ((long)(iph + 1) > (long)skb->data_end) return TC_ACT_STOLEN; return TC_ACT_OK; } Per discussion with Yonghong and Alexei [1], comparison of two packet pointers is not a pointer leak. This patch fixes it. Our local kernel is 6.1.y and we expect this fix to be backported to 6.1.y, so stable is CCed.

[PATCH net] batman-adv: Hold rtnl lock during MTU update via netlink

by Sven Eckelmann

The automatic recalculation of the maximum allowed MTU is usually triggered by code sections which are already rtnl lock protected by callers outside of batman-adv. But when the fragmentation setting is changed via batman-adv's own batadv genl family, then the rtnl lock is not yet taken. But dev_set_mtu requires that the caller holds the rtnl lock because it uses netdevice notifiers. And this code will then fail the check for this lock: RTNL: assertion failed at net/core/dev.c (1953) Cc: stable(a)vger.kernel.org Reported-by: syzbot+f8812454d9b3ac00d282(a)syzkaller.appspotmail.com Fixes: c6a953cce8d0 ("batman-adv: Trigger events for auto adjusted MTU") Signed-off-by: Sven Eckelmann <sven(a)narfation.org> --- This problem was just identified by syzbot [1].

[PATCH v2] tpm: Enable hwrng only for Pluton on AMD CPUs

by Jarkko Sakkinen

The vendor check introduced by commit 554b841d4703 ("tpm: Disable RNG for all AMD fTPMs") doesn't work properly on a number of Intel fTPMs. On the reported systems the TPM doesn't reply at bootup and returns back the command code. This makes the TPM fail probe. Since only Microsoft Pluton is the only known combination of AMD CPU and fTPM from other vendor, disable hwrng otherwise. In order to make sysadmin aware of this, print also info message to the klog.

[PATCH v1] mmc: sdhci-pci-gli: fix LPM negotiation so x86/S0ix SoCs can suspend

by Sven van Ashbrook

To improve the r/w performance of GL9763E, the current driver inhibits LPM negotiation while the device is active. This prevents a large number of SoCs from suspending, notably x86 systems which use S0ix as the suspend mechanism: 1. Userspace initiates s2idle suspend (e.g. via writing to /sys/power/state) 2. This switches the runtime_pm device state to active, which disables LPM negotiation, then calls the "regular" suspend callback 3. With LPM negotiation disabled, the bus cannot enter low-power state 4. On a large number of SoCs, if the bus not in a low-power state, S0ix cannot be entered, which in turn prevents the SoC from entering suspend.

[PATCH v2] tpm: Don't make vendor check required for probe

by Mario Limonciello

The vendor check introduced by commit 554b841d4703 ("tpm: Disable RNG for all AMD fTPMs") doesn't work properly on a number of Intel fTPMs. On the reported systems the TPM doesn't reply at bootup and returns back the command code. This makes the TPM fail probe. As this isn't crucial for anything but AMD fTPM and AMD fTPM works, check the chip vendor and if it's not AMD don't run the checks.

[PATCH v1 9/9] media: qcom: camss: Fix csid-gen2 for test pattern generator

by Bryan O'Donoghue

From: Andrey Konovalov <andrey.konovalov(a)linaro.org> In the current driver csid Test Pattern Generator (TPG) doesn't work. This change: - fixes writing frame width and height values into CSID_TPG_DT_n_CFG_0 - fixes the shift by one between test_pattern control value and the actual pattern. So that TPG starts working, but with the below limitations: - only test_pattern=9 works as it should - test_pattern=8 and test_pattern=7 produce black frame (all zeroes) - the rest of test_pattern's don't work (yavta doesn't get the data) - regardless of the CFA pattern set by 'media-ctl -V' the actual pixel order is always the same (RGGB for any RAW8 or RAW10P format in 4608x2592 resolution).

[PATCH v1 4/9] media: qcom: camss: Fix VFE-17x vfe_disable_output()

by Bryan O'Donoghue

There are two problems with the current vfe_disable_output() routine. Firstly we rightly use a spinlock to protect output->gen2.active_num everywhere except for in the IDLE timeout path of vfe_disable_output(). Even if that is not racy "in practice" somehow it is by happenstance not by design. Secondly we do not get consistent behaviour from this routine. On sc8280xp 50% of the time I get "VFE idle timeout - resetting". In this case the subsequent capture will succeed.

[PATCH v1 3/9] media: qcom: camss: Fix vfe_get() error jump

by Bryan O'Donoghue

Right now it is possible to do a vfe_get() with the internal reference count at 1. If vfe_check_clock_rates() returns non-zero then we will leave the reference count as-is and run: - pm_runtime_put_sync() - vfe->ops->pm_domain_off() skip: - camss_disable_clocks() Subsequent vfe_put() calls will when the ref-count is non-zero unconditionally run: - pm_runtime_put_sync() - vfe->ops->pm_domain_off() - camss_disable_clocks() vfe_get() should not attempt to roll-back on error when the ref-count is non-zero as the upper layers will still do their own vfe_put() operations. vfe_put() will drop the reference count and do the necessary power domain release, the cleanup jumps in vfe_get() should only be run when the ref-count is zero.

[PATCH v1 1/9] media: qcom: camss: Fix pm_domain_on sequence in probe

by Bryan O'Donoghue

We need to make sure camss_configure_pd() happens before camss_register_entities() as the vfe_get() path relies on the pointer provided by camss_configure_pd(). Fix the ordering sequence in probe to ensure the pointers vfe_get() demands are present by the time camss_register_entities() runs. In order to facilitate backporting to stable kernels I've moved the configure_pd() call pretty early on the probe() function so that irrespective of the existence of the old error handling jump labels this patch should still apply to -next circa Aug 2023 to v5.13 inclusive.

[PATCH v3] usb: typec: tcpci: clear the fault status bit

by Fabio Estevam

From: Marco Felsch <m.felsch(a)pengutronix.de> According the "USB Type-C Port Controller Interface Specification v2.0" the TCPC sets the fault status register bit-7 (AllRegistersResetToDefault) once the registers have been reset to their default values. This triggers an alert(-irq) on PTN5110 devices albeit we do mask the fault-irq, which may cause a kernel hang. Fix this generically by writing a one to the corresponding bit-7.

[PATCH v2] pinctrl: cherryview: fix address_space_handler() argument

[PATCH v3] fsverity: skip PKCS#7 parser when keyring is empty

by Eric Biggers

From: Eric Biggers <ebiggers(a)google.com> If an fsverity builtin signature is given for a file but the ".fs-verity" keyring is empty, there's no real reason to run the PKCS#7 parser. Skip this to avoid the PKCS#7 attack surface when builtin signature support is configured into the kernel but is not being used. This is a hardening improvement, not a fix per se, but I've added Fixes and Cc stable to get it out to more users.

[CI 1/2] drm: Add an HPD poll helper to reschedule the poll work

Add a helper to reschedule drm_mode_config::output_poll_work after polling has been enabled for a connector (and needing a reschedule, since previously polling was disabled for all connectors and hence output_poll_work was not running).

[PATCH v3 1/2] ata: pata_falcon: fix IO base selection for Q40

by Michael Schmitz

With commit 44b1fbc0f5f3 ("m68k/q40: Replace q40ide driver with pata_falcon and falconide"), the Q40 IDE driver was replaced by pata_falcon.c. Both IO and memory resources were defined for the Q40 IDE platform device, but definition of the IDE register addresses was modeled after the Falcon case, both in use of the memory resources and in including register scale and byte vs. word offset in the address. This was correct for the Falcon case, which does not apply any address translation to the register addresses. In the Q40 case, all of device base address, byte access offset and register scaling is included in the platform specific ISA access translation (in asm/mm_io.h). As a consequence, such address translation gets applied twice, and register addresses are mangled. Use the device base address from the platform IO resource, and use standard register offsets from that base in order to calculate register addresses (the IO address translation will then apply the correct ISA window base and scaling). Encode PIO_OFFSET into IO port addresses for all registers except the data transfer register. Encode the MMIO offset there (pata_falcon_data_xfer() directly uses raw IO with no address translation).

[PATCH V2] rcu: Update jiffies locally in rcu_cpu_stall_reset()

But jiffies is only updated in the timer interrupt, so when kgdb_cpu_enter() begins to run there may already be nearly one rcu check period after jiffies. Since all interrupts are disabled during kgdb_cpu_enter(), jiffies will not be updated. When kgdb_cpu_enter() returns, rcu_state.jiffies_stall maybe already gets timeout. We can set rcu_state.jiffies_stall to two rcu check periods later, e.g. jiffies + (rcu_jiffies_till_stall_check() * 2) in rcu_cpu_stall_reset() to avoid this problem. But this isn't a complete solution because kgdb may take a very long time in irq disabled context. Instead, update jiffies at the beginning of rcu_cpu_stall_reset() can solve all kinds of problems [1]. But this causes a new problem because updating jiffies is not NMI safe while rcu_cpu_stall_reset() may be used in NMI context. So we don't update the global jiffies, but only add the time 'delta' to jiffies locally at the beginning of rcu_cpu_stall_reset() which has the same effect.

[for-linus][PATCH 3/8] tracing/synthetic: Use union instead of casts

by Steven Rostedt

From: Sven Schnelle <svens(a)linux.ibm.com> The current code uses a lot of casts to access the fields member in struct synth_trace_events with different sizes. This makes the code hard to read, and had already introduced an endianness bug. Use a union and struct instead.

[PATCH 0/6] Backport rework of deadline bandwidth restoration for 6.1.y

by Qais Yousef

This is a backport of the series that fixes the way deadline bandwidth restoration is done which is causing noticeable delay on resume path. It also converts the cpuset lock back into a mutex which some users on Android too. I lack the details but AFAIU the read/write semaphore was slower on high contention. Compile tested against some randconfig for different archs and tested against android14-6.1 GKI kernel. My testing is limited to resume path only; and general phone usage to make sure nothing falls apart. Would be good to have some deadline specific testing done too. Based on v6.1.46 Original series: https://lore.kernel.org/lkml/20230508075854.17215-1-juri.lelli@redhat.com/ Thanks! -- Qais Yousef Dietmar Eggemann (2): sched/deadline: Create DL BW alloc, free & check overflow interface cgroup/cpuset: Free DL BW in case can_attach() fails Juri Lelli (4): cgroup/cpuset: Rename functions dealing with DEADLINE accounting sched/cpuset: Bring back cpuset_mutex sched/cpuset: Keep track of SCHED_DEADLINE task in cpusets cgroup/cpuset: Iterate only if DEADLINE tasks are present include/linux/cpuset.h | 12 +- include/linux/sched.h | 4 +- kernel/cgroup/cgroup.c | 4 + kernel/cgroup/cpuset.c | 246 ++++++++++++++++++++++++++-------------- kernel/sched/core.c | 41 +++---- kernel/sched/deadline.c | 67 ++++++++--- kernel/sched/sched.h | 2 +- 7 files changed, 246 insertions(+), 130 deletions(-) -- 2.34.1

This is because nilfs2 keeps buffer pointers in local structures for some metadata and reuses them, but such buffers may be forcibly discarded by nilfs_clear_dirty_page() in some critical situations. This issue is reported to appear after commit 28a65b49eb53 ("nilfs2: do not write dirty data after degenerating to read-only"), but the issue has potentially existed before. Fix this issue by checking the uptodate flag when attempting to reuse an internally held buffer, and reloading the metadata instead of reusing the buffer if the flag was lost.

[merged mm-stable] memfd-replace-ratcheting-feature-from-vmmemfd_noexec-with-hierarchy.patch removed from -mm tree

by Andrew Morton

The quilt patch titled Subject: memfd: replace ratcheting feature from vm.memfd_noexec with hierarchy has been removed from the -mm tree. Its filename was memfd-replace-ratcheting-feature-from-vmmemfd_noexec-with-hierarchy.patch This patch was dropped because it was merged into the mm-stable branch of git://git.kernel.org/pub/scm/linux/kernel/git/akpm/mm ------------------------------------------------------ From: Aleksa Sarai <cyphar(a)cyphar.com> Subject: memfd: replace ratcheting feature from vm.memfd_noexec with hierarchy Date: Mon, 14 Aug 2023 18:41:00 +1000 This sysctl has the very unusual behaviour of not allowing any user (even CAP_SYS_ADMIN) to reduce the restriction setting, meaning that if you were to set this sysctl to a more restrictive option in the host pidns you would need to reboot your machine in order to reset it. The justification given in [1] is that this is a security feature and thus it should not be possible to disable. Aside from the fact that we have plenty of security-related sysctls that can be disabled after being enabled (fs.protected_symlinks for instance), the protection provided by the sysctl is to stop users from being able to create a binary and then execute it. A user with CAP_SYS_ADMIN can trivially do this without memfd_create(2): % cat mount-memfd.c #include <fcntl.h> #include <string.h> #include <stdio.h> #include <stdlib.h> #include <unistd.h> #include <linux/mount.h> #define SHELLCODE "#!/bin/echo this file was executed from this totally private tmpfs:" int main(void) { int fsfd = fsopen("tmpfs", FSOPEN_CLOEXEC); assert(fsfd >= 0); assert(!fsconfig(fsfd, FSCONFIG_CMD_CREATE, NULL, NULL, 2)); int dfd = fsmount(fsfd, FSMOUNT_CLOEXEC, 0); assert(dfd >= 0); int execfd = openat(dfd, "exe", O_CREAT | O_RDWR | O_CLOEXEC, 0782); assert(execfd >= 0); assert(write(execfd, SHELLCODE, strlen(SHELLCODE)) == strlen(SHELLCODE)); assert(!close(execfd)); char *execpath = NULL; char *argv[] = { "bad-exe", NULL }, *envp[] = { NULL }; execfd = openat(dfd, "exe", O_PATH | O_CLOEXEC); assert(execfd >= 0); assert(asprintf(&execpath, "/proc/self/fd/%d", execfd) > 0); assert(!execve(execpath, argv, envp)); } % ./mount-memfd this file was executed from this totally private tmpfs: /proc/self/fd/5 % Given that it is possible for CAP_SYS_ADMIN users to create executable binaries without memfd_create(2) and without touching the host filesystem (not to mention the many other things a CAP_SYS_ADMIN process would be able to do that would be equivalent or worse), it seems strange to cause a fair amount of headache to admins when there doesn't appear to be an actual security benefit to blocking this. There appear to be concerns about confused-deputy-esque attacks[2] but a confused deputy that can write to arbitrary sysctls is a bigger security issue than executable memfds. /* New API */ The primary requirement from the original author appears to be more based on the need to be able to restrict an entire system in a hierarchical manner[3], such that child namespaces cannot re-enable executable memfds. So, implement that behaviour explicitly -- the vm.memfd_noexec scope is evaluated up the pidns tree to &init_pid_ns and you have the most restrictive value applied to you. The new lower limit you can set vm.memfd_noexec is whatever limit applies to your parent. Note that a pidns will inherit a copy of the parent pidns's effective vm.memfd_noexec setting at unshare() time. This matches the existing behaviour, and it also ensures that a pidns will never have its vm.memfd_noexec setting *lowered* behind its back (but it will be raised if the parent raises theirs). /* Backwards Compatibility */ As the previous version of the sysctl didn't allow you to lower the setting at all, there are no backwards compatibility issues with this aspect of the change. However it should be noted that now that the setting is completely hierarchical. Previously, a cloned pidns would just copy the current pidns setting, meaning that if the parent's vm.memfd_noexec was changed it wouldn't propoagate to existing pid namespaces. Now, the restriction applies recursively. This is a uAPI change, however: * The sysctl is very new, having been merged in 6.3. * Several aspects of the sysctl were broken up until this patchset and the other patchset by Jeff Xu last month. And thus it seems incredibly unlikely that any real users would run into this issue. In the worst case, if this causes userspace isues we could make it so that modifying the setting follows the hierarchical rules but the restriction checking uses the cached copy.

[merged mm-stable] memfd-improve-userspace-warnings-for-missing-exec-related-flags.patch removed from -mm tree

by Andrew Morton

The quilt patch titled Subject: memfd: improve userspace warnings for missing exec-related flags has been removed from the -mm tree. Its filename was memfd-improve-userspace-warnings-for-missing-exec-related-flags.patch This patch was dropped because it was merged into the mm-stable branch of git://git.kernel.org/pub/scm/linux/kernel/git/akpm/mm ------------------------------------------------------ From: Aleksa Sarai <cyphar(a)cyphar.com> Subject: memfd: improve userspace warnings for missing exec-related flags Date: Mon, 14 Aug 2023 18:40:59 +1000 In order to incentivise userspace to switch to passing MFD_EXEC and MFD_NOEXEC_SEAL, we need to provide a warning on each attempt to call memfd_create() without the new flags. pr_warn_once() is not useful because on most systems the one warning is burned up during the boot process (on my system, systemd does this within the first second of boot) and thus userspace will in practice never see the warnings to push them to switch to the new flags. The original patchset[1] used pr_warn_ratelimited(), however there were concerns about the degree of spam in the kernel log[2,3]. The resulting inability to detect every case was flagged as an issue at the time[4]. While we could come up with an alternative rate-limiting scheme such as only outputting the message if vm.memfd_noexec has been modified, or only outputting the message once for a given task, these alternatives have downsides that don't make sense given how low-stakes a single kernel warning message is. Switching to pr_info_ratelimited() instead should be fine -- it's possible some monitoring tool will be unhappy with a stream of warning-level messages but there's already plenty of info-level message spam in dmesg.

[merged mm-stable] memfd-do-not-eacces-old-memfd_create-users-with-vmmemfd_noexec=2.patch removed from -mm tree

by Andrew Morton

The quilt patch titled Subject: memfd: do not -EACCES old memfd_create() users with vm.memfd_noexec=2 has been removed from the -mm tree. Its filename was memfd-do-not-eacces-old-memfd_create-users-with-vmmemfd_noexec=2.patch This patch was dropped because it was merged into the mm-stable branch of git://git.kernel.org/pub/scm/linux/kernel/git/akpm/mm ------------------------------------------------------ From: Aleksa Sarai <cyphar(a)cyphar.com> Subject: memfd: do not -EACCES old memfd_create() users with vm.memfd_noexec=2 Date: Mon, 14 Aug 2023 18:40:58 +1000 Given the difficulty of auditing all of userspace to figure out whether every memfd_create() user has switched to passing MFD_EXEC and MFD_NOEXEC_SEAL flags, it seems far less distruptive to make it possible for older programs that don't make use of executable memfds to run under vm.memfd_noexec=2. Otherwise, a small dependency change can result in spurious errors. For programs that don't use executable memfds, passing MFD_NOEXEC_SEAL is functionally a no-op and thus having the same In addition, every failure under vm.memfd_noexec=2 needs to print to the kernel log so that userspace can figure out where the error came from. The concerns about pr_warn_ratelimited() spam that caused the switch to pr_warn_once()[1,2] do not apply to the vm.memfd_noexec=2 case. This is a user-visible API change, but as it allows programs to do something that would be blocked before, and the sysctl itself was broken and recently released, it seems unlikely this will cause any issues.

[merged mm-stable] mm-unstable-multi-gen-lru-avoid-race-in-inc_min_seq.patch removed from -mm tree

The quilt patch titled Subject: Multi-gen LRU: avoid race in inc_min_seq() has been removed from the -mm tree. Its filename was mm-unstable-multi-gen-lru-avoid-race-in-inc_min_seq.patch This patch was dropped because it was merged into the mm-stable branch of git://git.kernel.org/pub/scm/linux/kernel/git/akpm/mm ------------------------------------------------------ From: Kalesh Singh <kaleshsingh(a)google.com> Subject: Multi-gen LRU: avoid race in inc_min_seq() Date: Tue, 1 Aug 2023 19:56:03 -0700 inc_max_seq() will try to inc_min_seq() if nr_gens == MAX_NR_GENS. This is because the generations are reused (the last oldest now empty generation will become the next youngest generation). inc_min_seq() is retried until successful, dropping the lru_lock and yielding the CPU on each failure, and retaking the lock before trying again: while (!inc_min_seq(lruvec, type, can_swap)) { spin_unlock_irq(&lruvec->lru_lock); cond_resched(); spin_lock_irq(&lruvec->lru_lock); } However, the initial condition that required incrementing the min_seq (nr_gens == MAX_NR_GENS) is not retested. This can change by another call to inc_max_seq() from run_aging() with force_scan=true from the debugfs interface. Since the eviction stalls when the nr_gens == MIN_NR_GENS, avoid unnecessarily incrementing the min_seq by rechecking the number of generations before each attempt. This issue was uncovered in previous discussion on the list by Yu Zhao and Aneesh Kumar [1].

[merged mm-stable] mm-unstable-multi-gen-lru-fix-per-zone-reclaim.patch removed from -mm tree

by Andrew Morton

The quilt patch titled Subject: Multi-gen LRU: fix per-zone reclaim has been removed from the -mm tree. Its filename was mm-unstable-multi-gen-lru-fix-per-zone-reclaim.patch This patch was dropped because it was merged into the mm-stable branch of git://git.kernel.org/pub/scm/linux/kernel/git/akpm/mm ------------------------------------------------------ From: Kalesh Singh <kaleshsingh(a)google.com> Subject: Multi-gen LRU: fix per-zone reclaim Date: Tue, 1 Aug 2023 19:56:02 -0700 MGLRU has a LRU list for each zone for each type (anon/file) in each generation: long nr_pages[MAX_NR_GENS][ANON_AND_FILE][MAX_NR_ZONES]; The min_seq (oldest generation) can progress independently for each type but the max_seq (youngest generation) is shared for both anon and file. This is to maintain a common frame of reference. In order for eviction to advance the min_seq of a type, all the per-zone lists in the oldest generation of that type must be empty. The eviction logic only considers pages from eligible zones for eviction or promotion. scan_folios() { ... for (zone = sc->reclaim_idx; zone >= 0; zone--) { ... sort_folio(); // Promote ... isolate_folio(); // Evict } ... } Consider the system has the movable zone configured and default 4 generations. The current state of the system is as shown below (only illustrating one type for simplicity): Type: ANON Zone DMA32 Normal Movable Device Gen 0 0 0 4GB 0 Gen 1 0 1GB 1MB 0 Gen 2 1MB 4GB 1MB 0 Gen 3 1MB 1MB 1MB 0 Now consider there is a GFP_KERNEL allocation request (eligible zone index <= Normal), evict_folios() will return without doing any work since there are no pages to scan in the eligible zones of the oldest generation. Reclaim won't make progress until triggered from a ZONE_MOVABLE allocation request; which may not happen soon if there is a lot of free memory in the movable zone. This can lead to OOM kills, although there is 1GB pages in the Normal zone of Gen 1 that we have not yet tried to reclaim. This issue is not seen in the conventional active/inactive LRU since there are no per-zone lists. If there are no (not enough) folios to scan in the eligible zones, move folios from ineligible zone (zone_index > reclaim_index) to the next generation. This allows for the progression of min_seq and reclaiming from the next generation (Gen 1). Qualcomm, Mediatek and raspberrypi [1] discovered this issue independently.

This can happen during reclaim if the memcg has already been offlined, and we reclaim all remaining pages attributed to the offlined memcg. shrink_many attempts to skip the empty memcg in this case, and continue reclaiming from the remaining memcgs in the old generation. If there is only one memcg remaining, or if all remaining memcgs are in the process of being released then shrink_many will spin until all memcgs have finished being released.

It could lead to a panic since on some architectures (like powerpc), the page table walker could see the wrong pte value and trigger a spurious page fault that can not be resolved (see commit f1cb8f9beba8 ("powerpc/64s/radix: avoid ptesync after set_pte and ptep_set_access_flags")). But actually the patch is aiming at riscv: the riscv specification allows the caching of invalid entries in the TLB, and since we recently removed the vmalloc page fault handling, we now need to emit a tlb shootdown whenever a new vmalloc mapping is emitted (https://lore.kernel.org/linux-riscv/20230725132246.817726-1-alexghiti@rivos…).

The quilt patch titled Subject: mm/gup: handle cont-PTE hugetlb pages correctly in gup_must_unshare() via GUP-fast has been removed from the -mm tree. Its filename was mm-gup-handle-cont-pte-hugetlb-pages-correctly-in-gup_must_unshare-via-gup-fast.patch This patch was dropped because it was merged into the mm-hotfixes-stable branch of git://git.kernel.org/pub/scm/linux/kernel/git/akpm/mm ------------------------------------------------------ From: David Hildenbrand <david(a)redhat.com> Subject: mm/gup: handle cont-PTE hugetlb pages correctly in gup_must_unshare() via GUP-fast Date: Sat, 5 Aug 2023 12:12:56 +0200 In contrast to most other GUP code, GUP-fast common page table walking code like gup_pte_range() also handles hugetlb pages. But in contrast to other hugetlb page table walking code, it does not look at the hugetlb PTE abstraction whereby we have only a single logical hugetlb PTE per hugetlb page, even when using multiple cont-PTEs underneath -- which is for example what huge_ptep_get() abstracts. So when we have a hugetlb page that is mapped via cont-PTEs, GUP-fast might stumble over a PTE that does not map the head page of a hugetlb page -- not the first "head" PTE of such a cont mapping. Logically, the whole hugetlb page is mapped (entire_mapcount == 1), but we might end up calling gup_must_unshare() with a tail page of a hugetlb page. We only maintain a single PageAnonExclusive flag per hugetlb page (as hugetlb pages cannot get partially COW-shared), stored for the head page. That flag is clear for all tail pages. So when gup_must_unshare() ends up calling PageAnonExclusive() with a tail page of a hugetlb page: 1) With CONFIG_DEBUG_VM_PGFLAGS Stumbles over the: VM_BUG_ON_PGFLAGS(PageHuge(page) && !PageHead(page), page); For example, when executing the COW selftests with 64k hugetlb pages on arm64: [ 61.082187] page:00000000829819ff refcount:3 mapcount:1 mapping:0000000000000000 index:0x1 pfn:0x11ee11 [ 61.082842] head:0000000080f79bf7 order:4 entire_mapcount:1 nr_pages_mapped:0 pincount:2 [ 61.083384] anon flags: 0x17ffff80003000e(referenced|uptodate|dirty|head|mappedtodisk|node=0|zone=2|lastcpupid=0xfffff) [ 61.084101] page_type: 0xffffffff() [ 61.084332] raw: 017ffff800000000 fffffc00037b8401 0000000000000402 0000000200000000 [ 61.084840] raw: 0000000000000010 0000000000000000 00000000ffffffff 0000000000000000 [ 61.085359] head: 017ffff80003000e ffffd9e95b09b788 ffffd9e95b09b788 ffff0007ff63cf71 [ 61.085885] head: 0000000000000000 0000000000000002 00000003ffffffff 0000000000000000 [ 61.086415] page dumped because: VM_BUG_ON_PAGE(PageHuge(page) && !PageHead(page)) [ 61.086914] ------------[ cut here ]------------ [ 61.087220] kernel BUG at include/linux/page-flags.h:990!

GUP-fast will fallback to ordinary GUP. As ordinary GUP properly considers the logical hugetlb PTE abstraction in hugetlb_follow_page_mask(), pinning the page will succeed when looking at the PageAnonExclusive on the head page only. So the only real effect of this is that with cont-PTE hugetlb pages, we'll always fallback from GUP-fast to ordinary GUP when not working on the head page, which ends up checking the head page and do the right thing. Consequently, the cow selftests pass with cont-PTE hugetlb pages as well without CONFIG_DEBUG_VM_PGFLAGS. Note that this only applies to anon hugetlb pages that are mapped using cont-PTEs: for example 64k hugetlb pages on a 4k arm64 kernel. ... and only when R/O-pinning (FOLL_PIN) such pages that are mapped into the page table R/O using GUP-fast. On production kernels (and even most debug kernels, that don't set CONFIG_DEBUG_VM_PGFLAGS) this patch should theoretically not be required to be backported. But of course, it does not hurt.

[merged mm-hotfixes-stable] mm-enable-page-walking-api-to-lock-vmas-during-the-walk.patch removed from -mm tree

by Andrew Morton

The quilt patch titled Subject: mm: enable page walking API to lock vmas during the walk has been removed from the -mm tree. Its filename was mm-enable-page-walking-api-to-lock-vmas-during-the-walk.patch This patch was dropped because it was merged into the mm-hotfixes-stable branch of git://git.kernel.org/pub/scm/linux/kernel/git/akpm/mm ------------------------------------------------------ From: Suren Baghdasaryan <surenb(a)google.com> Subject: mm: enable page walking API to lock vmas during the walk Date: Fri, 4 Aug 2023 08:27:19 -0700 walk_page_range() and friends often operate under write-locked mmap_lock. With introduction of vma locks, the vmas have to be locked as well during such walks to prevent concurrent page faults in these areas. Add an additional member to mm_walk_ops to indicate locking requirements for the walk. The change ensures that page walks which prevent concurrent page faults by write-locking mmap_lock, operate correctly after introduction of per-vma locks. With per-vma locks page faults can be handled under vma lock without taking mmap_lock at all, so write locking mmap_lock would not stop them. The change ensures vmas are properly locked during such walks. A sample issue this solves is do_mbind() performing queue_pages_range() to queue pages for migration. Without this change a concurrent page can be faulted into the area and be left out of migration.

Its filename was mm-gup-reintroduce-foll_numa-as-foll_honor_numa_fault.patch This patch was dropped because it was merged into the mm-hotfixes-stable branch of git://git.kernel.org/pub/scm/linux/kernel/git/akpm/mm ------------------------------------------------------ From: David Hildenbrand <david(a)redhat.com> Subject: mm/gup: reintroduce FOLL_NUMA as FOLL_HONOR_NUMA_FAULT Date: Thu, 3 Aug 2023 16:32:02 +0200 Unfortunately commit 474098edac26 ("mm/gup: replace FOLL_NUMA by gup_can_follow_protnone()") missed that follow_page() and follow_trans_huge_pmd() never implicitly set FOLL_NUMA because they really don't want to fail on PROT_NONE-mapped pages -- either due to NUMA hinting or due to inaccessible (PROT_NONE) VMAs. As spelled out in commit 0b9d705297b2 ("mm: numa: Support NUMA hinting page faults from gup/gup_fast"): "Other follow_page callers like KSM should not use FOLL_NUMA, or they would fail to get the pages if they use follow_page instead of get_user_pages." liubo reported [1] that smaps_rollup results are imprecise, because they miss accounting of pages that are mapped PROT_NONE. Further, it's easy to reproduce that KSM no longer works on inaccessible VMAs on x86-64, because pte_protnone()/pmd_protnone() also indictaes "true" in inaccessible VMAs, and follow_page() refuses to return such pages right now. As KVM really depends on these NUMA hinting faults, removing the pte_protnone()/pmd_protnone() handling in GUP code completely is not really an option. To fix the issues at hand, let's revive FOLL_NUMA as FOLL_HONOR_NUMA_FAULT to restore the original behavior for now and add better comments. Set FOLL_HONOR_NUMA_FAULT independent of FOLL_FORCE in is_valid_gup_args(), to add that flag for all external GUP users. Note that there are three GUP-internal __get_user_pages() users that don't end up calling is_valid_gup_args() and consequently won't get FOLL_HONOR_NUMA_FAULT set. 1) get_dump_page(): we really don't want to handle NUMA hinting faults. It specifies FOLL_FORCE and wouldn't have honored NUMA hinting faults already. 2) populate_vma_page_range(): we really don't want to handle NUMA hinting faults. It specifies FOLL_FORCE on accessible VMAs, so it wouldn't have honored NUMA hinting faults already. 3) faultin_vma_page_range(): we similarly don't want to handle NUMA hinting faults. To make the combination of FOLL_FORCE and FOLL_HONOR_NUMA_FAULT work in inaccessible VMAs properly, we have to perform VMA accessibility checks in gup_can_follow_protnone(). As GUP-fast should reject such pages either way in pte_access_permitted()/pmd_access_permitted() -- for example on x86-64 and arm64 that both implement pte_protnone() -- let's just always fallback to ordinary GUP when stumbling over pte_protnone()/pmd_protnone(). As Linus notes [2], honoring NUMA faults might only make sense for selected GUP users. So we should really see if we can instead let relevant GUP callers specify it manually, and not trigger NUMA hinting faults from GUP as default. Prepare for that by making FOLL_HONOR_NUMA_FAULT an external GUP flag and adding appropriate documenation. While at it, remove a stale comment from follow_trans_huge_pmd(): That comment for pmd_protnone() was added in commit 2b4847e73004 ("mm: numa: serialise parallel get_user_page against THP migration"), which noted: THP does not unmap pages due to a lack of support for migration entries at a PMD level. This allows races with get_user_pages Nowadays, we do have PMD migration entries, so the comment no longer applies. Let's drop it.

[PATCH v5 06/11] drm/radeon: Use RMW accessors for changing LNKCTL

by Ilpo Järvinen

Don't assume that only the driver would be accessing LNKCTL. ASPM policy changes can trigger write to LNKCTL outside of driver's control. And in the case of upstream bridge, the driver does not even own the device it's changing the registers for. Use RMW capability accessors which do proper locking to avoid losing concurrent updates to the register value.

[PATCH stable v4.14.y - v6.4.y] af_unix: Fix null-ptr-deref in unix_stream_sendpage().

by Kuniyuki Iwashima

Bing-Jhong Billy Jheng reported null-ptr-deref in unix_stream_sendpage() with detailed analysis and a nice repro. unix_stream_sendpage() tries to add data to the last skb in the peer's recv queue without locking the queue. If the peer's FD is passed to another socket and the socket's FD is passed to the peer, there is a loop between them. If we close both sockets without receiving FD, the sockets will be cleaned up by garbage collection. The garbage collection iterates such sockets and unlinks skb with FD from the socket's receive queue under the queue's lock. So, there is a race where unix_stream_sendpage() could access an skb locklessly that is being released by garbage collection, resulting in use-after-free. To avoid the issue, unix_stream_sendpage() must lock the peer's recv queue. Note the issue does not exist in 6.5+ thanks to the recent sendpage() refactoring. This patch is originally written by Linus Torvalds.

Howlett" <Liam.Howlett(a)oracle.com> Subject: maple_tree: disable mas_wr_append() when other readers are possible Date: Fri, 18 Aug 2023 20:43:55 -0400 The current implementation of append may cause duplicate data and/or incorrect ranges to be returned to a reader during an update. Although this has not been reported or seen, disable the append write operation while the tree is in rcu mode out of an abundance of caution. During the analysis of the mas_next_slot() the following was artificially created by separating the writer and reader code: Writer: reader: mas_wr_append set end pivot updates end metata Detects write to last slot last slot write is to start of slot store current contents in slot overwrite old end pivot mas_next_slot(): read end metadata read old end pivot return with incorrect range store new value Alternatively: Writer: reader: mas_wr_append set end pivot updates end metata Detects write to last slot last lost write to end of slot store value mas_next_slot(): read end metadata read old end pivot read new end pivot return with incorrect range set old end pivot There may be other accesses that are not safe since we are now updating both metadata and pointers, so disabling append if there could be rcu readers is the safest action.

[PATCH 5.15.y] exfat: check if filename entries exceeds max filename length

by Harshit Mogalapalli

From: Namjae Jeon <linkinjeon(a)kernel.org> [ Upstream commit d42334578eba1390859012ebb91e1e556d51db49 ] exfat_extract_uni_name copies characters from a given file name entry into the 'uniname' variable. This variable is actually defined on the stack of the exfat_readdir() function. According to the definition of the 'exfat_uni_name' type, the file name should be limited 255 characters (+ null teminator space), but the exfat_get_uniname_from_ext_entry() function can write more characters because there is no check if filename entries exceeds max filename length. This patch add the check not to copy filename characters when exceeding max filename length.

If the task had not previously used SME or we changed the vector length then the task will not have had TIF_SME set or backing storage for ZA/ZT allocated, resulting in inconsistent register sizes when saving state and spurious traps which flush the newly set register state. We should set TIF_SME to disable traps and ensure that storage is allocated for ZA and ZT if it is not already allocated. This requires modifying sme_alloc() to make the flush of any existing register state optional so we don't disturb existing state for ZA and ZT.

This cures VMEXIT doing potentially unret+IBPB or double IBPB. Also, the (SEV) VMEXIT case seems to have been overlooked. Redefine the meaning of the synthetic IBPB flags to: - ENTRY_IBPB -- issue IBPB on entry (was: entry + VMEXIT) - IBPB_ON_VMEXIT -- issue IBPB on VMEXIT And have 'retbleed=ibpb' set *BOTH* feature flags to ensure it retains the previous behaviour and issues IBPB on entry+VMEXIT. The new 'srso=ibpb_vmexit' option only sets IBPB_ON_VMEXIT. Create UNTRAIN_RET_VM specifically for the VMEXIT case, and have that check IBPB_ON_VMEXIT.

[PATCH v4 4.19 1/1] test_firmware: prevent race conditions by a correct implementation of locking

by Mirsad Goran Todorovac

[ Upstream commit 4acfe3dfde685a5a9eaec5555351918e2d7266a1 ] Dan Carpenter spotted a race condition in a couple of situations like these in the test_firmware driver: static int test_dev_config_update_u8(const char *buf, size_t size, u8 *cfg) { u8 val; int ret; ret = kstrtou8(buf, 10, &val); if (ret) return ret; mutex_lock(&test_fw_mutex); *(u8 *)cfg = val; mutex_unlock(&test_fw_mutex); /* Always return full write size even if we didn't consume all */ return size; } static ssize_t config_num_requests_store(struct device *dev, struct device_attribute *attr, const char *buf, size_t count) { int rc; mutex_lock(&test_fw_mutex); if (test_fw_config->reqs) { pr_err("Must call release_all_firmware prior to changing config\n"); rc = -EINVAL; mutex_unlock(&test_fw_mutex); goto out; } mutex_unlock(&test_fw_mutex); // NOTE: HERE is the race!!! Function can be preempted! // test_fw_config->reqs can change between the release of // the lock about and acquire of the lock in the // test_dev_config_update_u8() rc = test_dev_config_update_u8(buf, count, &test_fw_config->num_requests); out: return rc; } static ssize_t config_read_fw_idx_store(struct device *dev, struct device_attribute *attr, const char *buf, size_t count) { return test_dev_config_update_u8(buf, count, &test_fw_config->read_fw_idx); } The function test_dev_config_update_u8() is called from both the locked and the unlocked context, function config_num_requests_store() and config_read_fw_idx_store() which can both be called asynchronously as they are driver's methods, while test_dev_config_update_u8() and siblings change their argument pointed to by u8 *cfg or similar pointer. To avoid deadlock on test_fw_mutex, the lock is dropped before calling test_dev_config_update_u8() and re-acquired within test_dev_config_update_u8() itself, but alas this creates a race condition. Having two locks wouldn't assure a race-proof mutual exclusion. This situation is best avoided by the introduction of a new, unlocked function __test_dev_config_update_u8() which can be called from the locked context and reducing test_dev_config_update_u8() to: static int test_dev_config_update_u8(const char *buf, size_t size, u8 *cfg) { int ret; mutex_lock(&test_fw_mutex); ret = __test_dev_config_update_u8(buf, size, cfg); mutex_unlock(&test_fw_mutex); return ret; } doing the locking and calling the unlocked primitive, which enables both locked and unlocked versions without duplication of code.

A much more detailed description is in the first patch. The first patch addresses the race window. However, it adds a hugetlb_lock lock/unlock cycle to every vmemmap optimized hugetlb page free operation. This could lead to slowdowns if one is freeing a large number of hugetlb pages. The second path optimizes the update_and_free_pages_bulk routine to only take the lock once in bulk operations. The second patch is technically not a bug fix, but includes a Fixes tag and Cc stable to avoid a performance regression. It can be combined with the first, but was done separately make reviewing easier. This patch (of 2): Freeing a hugetlb page and releasing base pages back to the underlying allocator such as buddy or cma is performed in two steps: - remove_hugetlb_folio() is called to remove the folio from hugetlb lists, get a ref on the page and remove hugetlb destructor. This all must be done under the hugetlb lock. After this call, the page can be treated as a normal compound page or a collection of base size pages. - update_and_free_hugetlb_folio() is called to allocate vmemmap if needed and the free routine of the underlying allocator is called on the resulting page. We can not hold the hugetlb lock here. One issue with this scheme is that a memory error could occur between these two steps. In this case, the memory error handling code treats the old hugetlb page as a normal compound page or collection of base pages. It will then try to SetPageHWPoison(page) on the page with an error. If the page with error is a tail page without vmemmap, a write error will occur when trying to set the flag. Address this issue by modifying remove_hugetlb_folio() and update_and_free_hugetlb_folio() such that the hugetlb destructor is not cleared until after allocating vmemmap. Since clearing the destructor requires holding the hugetlb lock, the clearing is done in remove_hugetlb_folio() if the vmemmap is present. This saves a lock/unlock cycle. Otherwise, destructor is cleared in update_and_free_hugetlb_folio() after allocating vmemmap. Note that this will leave hugetlb pages in a state where they are marked free (by hugetlb specific page flag) and have a ref count. This is not a normal state. The only code that would notice is the memory error code, and it is set up to retry in such a case. A subsequent patch will create a routine to do bulk processing of vmemmap allocation. This will eliminate a lock/unlock cycle for each hugetlb page in the case where we are freeing a large number of pages.

proc_lseek backport request

by t.martitz＠avm.de

Dear stable team, I'm asking that commit 3f61631d47f1 ("take care to handle NULL ->proc_lseek()") gets backported to the stable and LTS kernels down to 5.10. Background: We are in the process of upgrading our kernels. One target kernel is based on 5.15 LTS. Here we found that, if proc file drivers do not implement proc_lseek, user space crashes easily, because various library routines internally perform lseek(2). The crash happens in proc_reg_llseek, where it wants to jump to a NULL pointer. We could, arguably, fix these drivers to use ".proc_lseek = no_llseek". But this doesn't seem like a worthwhile path forward, considering that latest Linux kernels (including 6.1 LTS) allow proc_lseek == NULL again and *remove* no_lseek. Essentially, on HEAD, it's best practice to leave proc_lseek == NULL. Therefore, I ask that the above procfs fix gets backported so that our drivers can work across all kernel versions, including latest 6.x. I checked that this commit applies and works as expected on a board that runs Linux 5.15, and the observed crash goes away. Furthermore, I investigated that the fix applies to older LTS kernels, down to 5.10. The lseek(2) path uses vfs_llseek() which checks for FMODE_LSEEK. This has been like that forever since the initial git import. However, 5.4 LTS and older kernels do not have "struct proc_ops". Thank you in advance. Best regards, Thomas Martitz

[PATCH 0/2] Backport unlink misfit patches into 6.1.y

by Qais Yousef

Decoupling misfit from overutilized better helps handling misfit due to uclamp_min only being misfit without triggering overutilized state, which is bad from energy point of view as it prematurely disables energy aware scheduling. The series also makes the search for a better CPU under bad thermal condition more comprehensive, which is useful improvement when the system is under bad thermal condition. Backports to 5.10.y and 5.15.y is hard as find_energy_efficient_cpu() is different. But it applies cleanly on 6.1.y Compile tested against various randconfigs for different archs. Boot tested on android14-6.1 GKI kernel.

[PATCH bpf-next 1/2] bpf: Fix issue in verifying allow_ptr_leaks

by Yafang Shao

After we converted the capabilities of our networking-bpf program from cap_sys_admin to cap_net_admin+cap_bpf, our networking-bpf program failed to start. Because it failed the bpf verifier, and the error log is "R3 pointer comparison prohibited". A simple reproducer as follows, SEC("cls-ingress") int ingress(struct __sk_buff *skb) { struct iphdr *iph = (void *)(long)skb->data + sizeof(struct ethhdr); if ((long)(iph + 1) > (long)skb->data_end) return TC_ACT_STOLEN; return TC_ACT_OK; } Per discussion with Yonghong and Alexei [1], comparison of two packet pointers is not a pointer leak. This patch fixes it. Our local kernel is 6.1.y and we expect this fix to be backported to 6.1.y, so stable is CCed.

A potential attacker could guess the returned handle value and closes it between the return of qxl_gem_object_create_with_handle() and the qobj usage, triggering a use-after-free scenario.

A potential attacker could guess the returned handle value and closes it between the return of qxl_gem_object_create_with_handle() and the qobj usage, triggering a use-after-free scenario. Reproducer: int dri_fd =-1; struct drm_mode_create_dumb arg = {0}; void gem_close(int handle); void* trigger(void* ptr) { int ret; arg.width = arg.height = 0x20; arg.bpp = 32; ret = ioctl(dri_fd,

A potential attacker could guess the returned handle value and closes it between the return of qxl_gem_object_create_with_handle() and the qobj usage, triggering a use-after-free scenario. Reproducer: int dri_fd =-1; struct drm_mode_create_dumb arg = {0}; void gem_close(int handle); void* trigger(void* ptr) { int ret; arg.width = arg.height = 0x20; arg.bpp = 32; ret = ioctl(dri_fd,

due to kernel taint Instead of returning a weak reference to the qxl_bo object, return the created drm_gem_object and let the caller decrement the reference count when it no longer needs it. As a convenience, if the caller is not interested in the gobj object, it can pass NULL to the parameter and the reference counting is descremented internally.

So if one of the binutils and GCC exceeds that version, we should explicitly specifying Zicsr and Zifencei via -march to cope with the new changes. but this only occurs when binutils >= 2.36 and GCC >= 11.1.0. It's a different story when binutils < 2.36. binutils-2.36 supports the Zifencei extension[2] and splits Zifencei and Zicsr from I[3]. GCC-11.1.0 is particular[4] because it add support Zicsr and Zifencei extension for -march. binutils-2.35 does not support the Zifencei extension, and does not need to specify Zicsr and Zifencei when working with GCC >= 12.1.0. To make our lives easier, let's relax the check to binutils >= 2.36 in CONFIG_TOOLCHAIN_NEEDS_EXPLICIT_ZICSR_ZIFENCEI. For the other two cases, where clang < 17 or GCC < 11.1.0, we will deal with them in CONFIG_TOOLCHAIN_NEEDS_OLD_ISA_SPEC.

So if one of the binutils and GCC exceeds that version, we should explicitly specifying Zicsr and Zifencei via -march to cope with the new changes. but this only occurs when binutils >= 2.36 and GCC >= 11.1.0. It's a different story when binutils < 2.36. binutils-2.36 supports the Zifencei extension[2] and splits Zifencei and Zicsr from I[3]. GCC-11.1.0 is particular[4] because it add support Zicsr and Zifencei extension for -march. binutils-2.35 does not support the Zifencei extension, and does not need to specify Zicsr and Zifencei when working with GCC >= 12.1.0.

[PATCH] pinctrl: amd: Mask wake bits on probe again

by Mario Limonciello

Shubhra reports that their laptop is heating up over s2idle. Even though it's getting into the deepest state, it appears to be having spurious wakeup events. While debugging a tangential issue with the RTC Carsten reports that recent 6.1.y based kernel face a similar problem. Looking at acpidump and GPIO register comparisons these spurious wakeup events are from the GPIO associated with the I2C touchpad on both laptops and occur even when the touchpad is not marked as a wake source by the kernel. This means that the boot firmware has programmed these bits and because Linux didn't touch them lead to spurious wakeup events from that GPIO. To fix this issue, restore most of the code that previously would clear all the bits associated with wakeup sources. This will allow the kernel to only program the wake up sources that are necessary. This is similar to what was done previously; but only the wake bits are cleared by default instead of interrupts and wake bits. If any other problems are reported then it may make sense to clear interrupts again too.

[PATCH] ACPI: resource: Fix IRQ override quirk for PCSpecialist Elimina Pro 16 M

by Hans de Goede

It turns out that some PCSpecialist Elimina Pro 16 M models have "GM6BGEQ" as DMI product-name instead of "Elimina Pro 16 M", causing the existing DMI quirk to not work on these models.

Your description is unclear to me, particularly what you call "is granted full access": do you mean chmod here ? If so, you can't delete it, so maybe you mean something else ? You should share a full reproducer showing the problem. Also, the fact that one command (touch) works and another one (python) does not indicates they don't do the same thing. So I suspect it's more related to the way the file is accessed where both commands use different semantics. As such, using strace on both commands showing the sequence accessing that file will reveal the difference and very likely explain why one can and the other cannot change the last modification date. Willy PS: there's no need to keep security@ here, it's used to dispatch issues to maintainers and coordinate fixes, now that your report is public it will not bring anything anymore.

[PATCH 1/3] m68k/q40: fix IO base selection for Q40 in pata_falcon.c

by Michael Schmitz

With commit 44b1fbc0f5f3 ("m68k/q40: Replace q40ide driver with pata_falcon and falconide"), the Q40 IDE driver was replaced by pata_falcon.c. Both IO and memory resources were defined for the Q40 IDE platform device, but definition of the IDE register addresses was modeled after the Falcon case, both in use of the memory resources and in including register scale and byte vs. word offset in the address. This was correct for the Falcon case, which does not apply any address translation to the register addresses. In the Q40 case, all of device base address, byte access offset and register scaling is included in the platform specific ISA access translation (in asm/mm_io.h). As a consequence, such address translation gets applied twice, and register addresses are mangled. Use the device base address from the platform IO resource, and use standard register offsets from that base in order to calculate register addresses (the IO address translation will then apply the correct ISA window base and scaling). Encode PIO_OFFSET into IO port addresses for all registers except the data transfer register. Encode the MMIO offset there (pata_falcon_data_xfer() directly uses raw IO with no address translation).

This issue only occurs when migration and reclamation occur at the same time. With our memory stress test, we can reproduce this issue several times a day. We have no idea why no one else encountered this issue. BTW, we switched to the new kernel version with this defect a few months ago. Since fullness and isolated share the same unsigned int, modifications of them should be protected by the same lock.

[PATCH 0/6] Backport rework of deadline bandwidth restoration for 5.10.y

by Qais Yousef

This is a backport of the series that fixes the way deadline bandwidth restoration is done which is causing noticeable delay on resume path. It also converts the cpuset lock back into a mutex which some users on Android too. I lack the details but AFAIU the read/write semaphore was slower on high contention. Compile tested against some randconfig for different archs and tested against android13-5.10 GKI kernel. My testing is limited to resume path only; and general phone usage to make sure nothing falls apart. Would be good to have some deadline specific testing done too. Based on v5.10.191 Original series: https://lore.kernel.org/lkml/20230508075854.17215-1-juri.lelli@redhat.com/ Thanks! -- Qais Yousef Dietmar Eggemann (2): sched/deadline: Create DL BW alloc, free & check overflow interface cgroup/cpuset: Free DL BW in case can_attach() fails Juri Lelli (4): cgroup/cpuset: Rename functions dealing with DEADLINE accounting sched/cpuset: Bring back cpuset_mutex sched/cpuset: Keep track of SCHED_DEADLINE task in cpusets cgroup/cpuset: Iterate only if DEADLINE tasks are present include/linux/cpuset.h | 12 ++- include/linux/sched.h | 4 +- kernel/cgroup/cgroup.c | 4 + kernel/cgroup/cpuset.c | 161 ++++++++++++++++++++++++++++------------ kernel/sched/core.c | 41 +++++----- kernel/sched/deadline.c | 66 ++++++++++++---- kernel/sched/sched.h | 2 +- 7 files changed, 202 insertions(+), 88 deletions(-) -- 2.34.1

Consider the following extent map layout PINNED [0 16K) [32K, 48K) and then we call btrfs_drop_extent_map_range for [0, 36K), with skip_pinned == true. The initial loop will have start = 0 end = 36K len = 36K we will find the [0, 16k) extent, but since we are pinned we will skip it, which has this code start = em_end; if (end != (u64)-1) len = start + len - em_end; em_end here is 16K, so now the values are start = 16K len = 16K + 36K - 16K = 36K len should instead be 20K. This is a problem when we find the next extent at [32K, 48K), we need to split this extent to leave [36K, 48k), however the code for the split looks like this split->start = start + len; split->len = em_end - (start + len); In this case we have em_end = 48K split->start = 16K + 36K // this should be 16K + 20K split->len = 48K - (16K + 36K) // this overflows as 16K + 36K is 52K and now we have an invalid extent_map in the tree that potentially overlaps other entries in the extent map. Even in the non-overlapping case we will have split->start set improperly, which will cause problems with any block related calculations. We don't actually need len in this loop, we can simply use end as our end point, and only adjust start up when we find a pinned extent we need to skip. Adjust the logic to do this, which keeps us from inserting an invalid extent map. We only skip_pinned in the relocation case, so this is relatively rare, except in the case where you are running relocation a lot, which can happen with auto relocation on.

These are typically compiler generated, but RET also emits this same. - it fudges the validation of the __x86_return_thunk symbol; because this symbol is inside another instruction, it can't actually find the instruction pointed to by the symbol offset and gets upset. Because these two things pertained to the same symbol, there was no pressing need to separate these two separate things. However, alas, along comes SRSO and more crazy things to deal with appeared. The SRSO patch itself added the following symbol names to identify as rethunk: 'srso_untrain_ret', 'srso_safe_ret' and '__ret' Where '__ret' is the old retbleed return thunk, 'srso_safe_ret' is a new similarly embedded return thunk, and 'srso_untrain_ret' is completely unrelated to anything the above does (and was only included because of that INT3 vs UD2 issue fixed previous). Clear things up by adding a second category for the embedded instruction thing.

[PATCH 0/6] Backport rework of deadline bandwidth restoration for 5.15.y

by Qais Yousef

This is a backport of the series that fixes the way deadline bandwidth restoration is done which is causing noticeable delay on resume path. It also converts the cpuset lock back into a mutex which some users on Android too. I lack the details but AFAIU the read/write semaphore was slower on high contention. Compile tested against some randconfig for different archs and tested against android14-5.15 GKI kernel, which already contains a version of this backport. My testing is limited to resume path only; and general phone usage to make sure nothing falls apart. Would be good to have some deadline specific testing done too. Based on v5.15.127 Original series: https://lore.kernel.org/lkml/20230508075854.17215-1-juri.lelli@redhat.com/ Thanks! -- Qais Yousef Dietmar Eggemann (2): sched/deadline: Create DL BW alloc, free & check overflow interface cgroup/cpuset: Free DL BW in case can_attach() fails Juri Lelli (4): cgroup/cpuset: Rename functions dealing with DEADLINE accounting sched/cpuset: Bring back cpuset_mutex sched/cpuset: Keep track of SCHED_DEADLINE task in cpusets cgroup/cpuset: Iterate only if DEADLINE tasks are present include/linux/cpuset.h | 12 ++- include/linux/sched.h | 4 +- kernel/cgroup/cgroup.c | 4 + kernel/cgroup/cpuset.c | 232 ++++++++++++++++++++++++++-------------- kernel/sched/core.c | 41 ++++--- kernel/sched/deadline.c | 66 +++++++++--- kernel/sched/sched.h | 2 +- 7 files changed, 238 insertions(+), 123 deletions(-) -- 2.34.1

Fwd: System becomes hot when put to sleep

by Bagas Sanjaya

Hi, I notice a regression report on Bugzilla [1]. Quoting from it: > I have a Dell Inspiron 14 5425 laptop with hardware specified below. Up till kernel version 6.1.39 the system can sleep and resume correctly but with kernel version 6.1.40 it heats up when put to sleep and drains battery very quickly. It seems CPU cannot suspend though the system can resume correctly and functions correctly after that. I believe many GPIO and pinctrl patches/fixes for the AMD platform beginning 6.1.40 and 6.4.5 has caused this issue. There is no error in logs and sleep/resume log messages in both 6.1.39 and 6.1.40 are the same. Only s2idle sleep mode is available on my system. > > -- CPU > AMD Ryzen 5 5625U with Radeon Graphics > > -- PCI > 00:00.0 Host bridge: Advanced Micro Devices, Inc.

[PATCH] rcu: Update jiffies locally in rcu_cpu_stall_reset()

But jiffies is only updated in the timer interrupt, so when kgdb_cpu_enter() begins to run there may already be nearly one rcu check period after jiffies. Since all interrupts are disabled during kgdb_cpu_enter(), jiffies will not be updated. When kgdb_cpu_enter() returns, rcu_state.jiffies_stall maybe already gets timeout. We can set rcu_state.jiffies_stall to two rcu check periods later, e.g. jiffies + (rcu_jiffies_till_stall_check() * 2) in rcu_cpu_stall_reset() to avoid this problem. But this isn't a complete solution because kgdb may take a very long time in irq disabled context. Instead, update jiffies at the beginning of rcu_cpu_stall_reset() can solve all kinds of problems [1]. But this causes a new problem because updating jiffies is not NMI safe while rcu_cpu_stall_reset() may be used in NMI context. So we don't update the global jiffies, but only add the time 'delta' to jiffies locally at the beginning of rcu_cpu_stall_reset() which has the same effect.

[PATCH] workingset: ensure memcg is valid for recency check

by Nhat Pham

In eviction recency check, we are currently not holding a local reference to the memcg that the refaulted folio belonged to when it was evicted. This could cause serious memcg lifetime issues, for e.g in the memcg hierarchy traversal done in mem_cgroup_get_nr_swap_pages().

[PATCH 1/5] batman-adv: Trigger events for auto adjusted MTU

by Simon Wunderlich

From: Sven Eckelmann <sven(a)narfation.org> If an interface changes the MTU, it is expected that an NETDEV_PRECHANGEMTU and NETDEV_CHANGEMTU notification events is triggered. This worked fine for .ndo_change_mtu based changes because core networking code took care of it. But for auto-adjustments after hard-interfaces changes, these events were simply missing. Due to this problem, non-batman-adv components weren't aware of MTU changes and thus couldn't perform their own tasks correctly.

[PATCHv3] x86/sgx: Avoid softlockup from sgx_vepc_release

by Jack Wang

We hit softlocup with following call trace: ? asm_sysvec_apic_timer_interrupt+0x16/0x20 xa_erase+0x21/0xb0 ? sgx_free_epc_page+0x20/0x50 sgx_vepc_release+0x75/0x220 __fput+0x89/0x250 task_work_run+0x59/0x90 do_exit+0x337/0x9a0 Similar like commit 8795359e35bc ("x86/sgx: Silence softlockup detection when releasing large enclaves"). The test system has 64GB of enclave memory, and all assigned to a single VM. Release vepc take longer time and triggers the softlockup warning. Add cond_resched() to give other tasks a chance to run and placate the softlockup detector.

This is because nilfs2 keeps buffer pointers in local structures for some metadata and reuses them, but such buffers may be forcibly discarded by nilfs_clear_dirty_page() in some critical situations. This issue is reported to appear after commit 28a65b49eb53 ("nilfs2: do not write dirty data after degenerating to read-only"), but the issue has potentially existed before. Fix this issue by checking the uptodate flag when attempting to reuse an internally held buffer, and reloading the metadata instead of reusing the buffer if the flag was lost.

[PATCH v13 01/12] PCI: Only put Intel PCIe ports >= 2015 into D3

by Mario Limonciello

commit 9d26d3a8f1b0 ("PCI: Put PCIe ports into D3 during suspend") changed pci_bridge_d3_possible() so that any vendor's PCIe ports from modern machines (>=2015) are allowed to be put into D3. Iain reports that USB devices can't be used to wake a Lenovo Z13 from suspend. This is because the PCIe root port has been put into D3 and AMD's platform can't handle USB devices waking in this case. This behavior is only reported on Linux. Comparing the behavior on Windows and Linux, Windows doesn't put the root ports into D3. To fix the issue without regressing existing Intel systems, limit the >=2015 check to only apply to Intel PCIe ports.

The following commit has been merged into the ras/core branch of tip: Commit-ID: 4240e2ebe67941ce2c4f5c866c3af4b5ac7a0c67 Gitweb: https://git.kernel.org/tip/4240e2ebe67941ce2c4f5c866c3af4b5ac7a0c67 Author: Yazen Ghannam <yazen.ghannam(a)amd.com> AuthorDate: Mon, 14 Aug 2023 15:08:53 -05:00 Committer: Borislav Petkov (AMD) <bp(a)alien8.de> CommitterDate: Fri, 18 Aug 2023 13:05:52 +02:00 x86/MCE: Always save CS register on AMD Zen IF Poison errors The Instruction Fetch (IF) units on current AMD Zen-based systems do not guarantee a synchronous #MC is delivered for poison consumption errors. Therefore, MCG_STATUS[EIPV|RIPV] will not be set. However, the microarchitecture does guarantee that the exception is delivered within the same context. In other words, the exact rIP is not known, but the context is known to not have changed. There is no architecturally-defined method to determine this behavior. The Code Segment (CS) register is always valid on such IF unit poison errors regardless of the value of MCG_STATUS[EIPV|RIPV]. Add a quirk to save the CS register for poison consumption from the IF unit banks. This is needed to properly determine the context of the error. Otherwise, the severity grading function will assume the context is IN_KERNEL due to the m->cs value being 0 (the initialized value). This leads to unnecessary kernel panics on data poison errors due to the kernel believing the poison consumption occurred in kernel context.

[PATCH v5] blk-crypto: dynamically allocate fallback profile

by Sweet Tea Dorminy

blk_crypto_profile_init() calls lockdep_register_key(), which warns and does not register if the provided memory is a static object. blk-crypto-fallback currently has a static blk_crypto_profile and calls blk_crypto_profile_init() thereupon, resulting in the warning and failure to register. Fortunately it is simple enough to use a dynamically allocated profile and make lockdep function correctly.

[PATCH 1/2] maple_tree: Disable mas_wr_append() when other readers are possible

by Liam R. Howlett

The current implementation of append may cause duplicate data and/or incorrect ranges to be returned to a reader during an update. Although this has not been reported or seen, disable the append write operation while the tree is in rcu mode out of an abundance of caution. During the analysis of the mas_next_slot() the following was artificially created by separating the writer and reader code: Writer: reader: mas_wr_append set end pivot updates end metata Detects write to last slot last slot write is to start of slot store current contents in slot overwrite old end pivot mas_next_slot(): read end metadata read old end pivot return with incorrect range store new value Alternatively: Writer: reader: mas_wr_append set end pivot updates end metata Detects write to last slot last lost write to end of slot store value mas_next_slot(): read end metadata read old end pivot read new end pivot return with incorrect range set old end pivot There may be other accesses that are not safe since we are now updating both metadata and pointers, so disabling append if there could be rcu readers is the safest action.

Request to add a patch to Stable Branch 6.1

by SG

(Before starting, i want to say i am not the developer of the patch, i am just an end user of a distribution kernel, which has just faced some problem, i don't even know if kernel team accepts patch requests from non dev, and thi mail is mostly shot in dark) Respected Sir/s/Ma'am/s I want to request that patch https://lore.kernel.org/all/20230627062442.54008-1-mika.westerberg@linux.in… be accepted in to the stable 6.1 branch, it is already present in the current branch, and i request for it to be backported. This fixes some Intel CPUs (according to other users claims, ranging back to 6th gen for some) not going to deeper c states with kernels 5.16+, and was fixed by this patch in 6.4.4+, since many institutions, and distributions use 6.1, it would be great if this is included (from what i understand from requirements (https://www.kernel.org/doc/html/latest/process/stable-kernel-rules.html) i guess it fits all) I was facing this issue for roughly a year, and then reported in debian(my distribution) forums, and we found nothing earlier (https://forums.debian.net/viewtopic.php?t=154875), then i posted on some other forums, and then i was asked to check if there was an active bug linux kernel tracker at that time, and i could not find one, so i decided to raise an issue (https://bugzilla.kernel.org/show_bug.cgi?id=217616), but just a few days prior to me posting someone had submiteed the patch, that i did not know of, since then i am using the newest kernel(in 6.4 branch) and am not facing issues. I apologize for all the foolishness of mine, and just making an humble request. Thank You

[PATCH] arm64/ptrace: Ensure that SME is set up for target when writing SSVE state

by Mark Brown

When we use NT_ARM_SSVE to either enable streaming mode or change the vector length for a process we do not currently do anything to ensure that there is storage allocated for the SME specific register state. If the task had not previously used SME or we changed the vector length then the task will not have had TIF_SME set or backing storage for ZA/ZT allocated, resulting in inconsistent register sizes when saving state and spurious traps which flush the newly set register state. We should set TIF_SME to disable traps and ensure that storage is allocated for ZA and ZT if it is not already allocated. This requires modifying sme_alloc() to make the flush of any existing register state optional so we don't disturb existing state for ZA and ZT.

[PATCH v10 4/6] serial: sc16is7xx: fix regression with GPIO configuration

by Hugo Villeneuve

From: Hugo Villeneuve <hvilleneuve(a)dimonoff.com> Commit 679875d1d880 ("sc16is7xx: Separate GPIOs from modem control lines") and commit 21144bab4f11 ("sc16is7xx: Handle modem status lines") changed the function of the GPIOs pins to act as modem control lines without any possibility of selecting GPIO function. As a consequence, applications that depends on GPIO lines configured by default as GPIO pins no longer work as expected. Also, the change to select modem control lines function was done only for channel A of dual UART variants (752/762). This was not documented in the log message. Allow to specify GPIO or modem control line function in the device tree, and for each of the ports (A or B). Do so by using the new device-tree property named "nxp,modem-control-line-ports" (property added in separate patch). When registering GPIO chip controller, mask-out GPIO pins declared as modem control lines according to this new DT property.

[PATCH v4] blk-crypto: dynamically allocate fallback profile

by Sweet Tea Dorminy

blk_crypto_profile_init() calls lockdep_register_key(), which warns and does not register if the provided memory is a static object. blk-crypto-fallback currently has a static blk_crypto_profile and calls blk_crypto_profile_init() thereupon, resulting in the warning and failure to register. Fortunately it is simple enough to use a dynamically allocated profile and make lockdep function correctly.

[PATCH] Revert "drm/edid: Fix csync detailed mode parsing"

by Jani Nikula

This reverts commit ca62297b2085b5b3168bd891ca24862242c635a1. Commit ca62297b2085 ("drm/edid: Fix csync detailed mode parsing") fixed EDID detailed mode sync parsing. Unfortunately, there are quite a few displays out there that have bogus (zero) sync field that are broken by the change. Zero means analog composite sync, which is not right for digital displays, and the modes get rejected. Regardless, it used to work, and it needs to continue to work. Revert the change. Rejecting modes with analog composite sync was the part that fixed the gitlab issue 8146 [1]. We'll need to get back to the drawing board with that.

[PATCH v2 0/3] don't use mapcount() to check large folio sharing

by Yin Fengwei

In madvise_cold_or_pageout_pte_range() and madvise_free_pte_range(), folio_mapcount() is used to check whether the folio is shared. But it's not correct as folio_mapcount() returns total mapcount of large folio. Use folio_estimated_sharers() here as the estimated number is enough. This patchset will fix the cases: User space application call madvise() with MADV_FREE, MADV_COLD and MADV_PAGEOUT for specific address range. There are THP mapped to the range. Without the patchset, the THP is skipped. With the patch, the THP will be split and handled accordingly. David reported the cow self test skip some cases because of MADV_PAGEOUT skip THP: https://lore.kernel.org/linux-mm/9e92e42d-488f-47db-ac9d-75b24cd0d037@intel… and I confirmed this patchset make it work again. Changelog from v1: - Avoid two Fixes tags make backport harder. Thank Andrew for pointing this out. - Add note section to mention this is a temporary fix which is fine to reduce user-visble effects. For long term fix, we should wait for David's solution. Thank Ryan and David for pointing this out. - Spell user-visible effects out. Then people could decide whether these patches are necessary for stable branch. Thank Andrew for pointing this out.

[PATCHv2] x86/sgx: Avoid softlockup from sgx_vepc_release

by Jack Wang

We hit softlocup with following call trace: ? asm_sysvec_apic_timer_interrupt+0x16/0x20 xa_erase+0x21/0xb0 ? sgx_free_epc_page+0x20/0x50 sgx_vepc_release+0x75/0x220 __fput+0x89/0x250 task_work_run+0x59/0x90 do_exit+0x337/0x9a0 Similar like commit 8795359e35bc ("x86/sgx: Silence softlockup detection when releasing large enclaves") The test system has 64GB of enclave memory, and all assigned to a single VM. Release vepc take longer time and triggers the softlockup warning. Add a cond_resched() to give other tasks a chance to run and placate the softlockup detector.
