Each change will take a time. `is_module_text_address()` and `__module_text_address()` works with MODULE_STATE_LIVE and MODULE_STATE_GOING. If we use `is_module_text_address()` and `__module_text_address()` separately, there is a chance that the first one is succeeded but the next one is failed because module->state becomes MODULE_STATE_UNFORMED between those operations. In `check_kprobe_address_safe()`, if the second `__module_text_address()` is failed, that is ignored because it expected a kernel_text address. But it may have failed simply because module->state has been changed to MODULE_STATE_UNFORMED. In this case, arm_kprobe() will try to modify non-exist module text address (use-after-free). To fix this problem, we should not use separated `is_module_text_address()` and `__module_text_address()`, but use only `__module_text_address()` once and do `try_module_get(module)` which is only available with MODULE_STATE_LIVE.

They both expect the result from a prior bpf_ringbuf_reserve() call which has a return type of RET_PTR_TO_ALLOC_MEM_OR_NULL. Meaning, after a NULL check in the code, the verifier will promote the register type in the non-NULL branch to a PTR_TO_MEM and in the NULL branch to a known zero scalar. Generally, pointer arithmetic on PTR_TO_MEM is allowed, so the latter could have an offset. The ARG_PTR_TO_ALLOC_MEM expects a PTR_TO_MEM register type. However, the non- zero result from bpf_ringbuf_reserve() must be fed into either bpf_ringbuf_submit() or bpf_ringbuf_discard() but with the original offset given it will then read out the struct bpf_ringbuf_hdr mapping. The verifier missed to enforce a zero offset, so that out of bounds access can be triggered which could be used to escalate privileges if unprivileged BPF was enabled (disabled by default in kernel).

[PATCH for-stable-6.1 00/23] x86/efistub backports

by Ard Biesheuvel

From: Ard Biesheuvel <ardb(a)kernel.org> This is the final batch of changes to bring linux-6.1.y in sync with 6.6 and later in terms of compatibility with tightened boot security requirements imposed by MicroSoft, compliance with which is a prerequisite for them to be willing to resume signing distro shim images with the MS 3rd party secure boot certificate. Without this, distros can only boot on off-the-shelf x86 PCs after disabling secure boot explicitly. Most of these changes appeared in v6.8 and have been backported to v6.6 already.

[PATCH] ASoC: ti: davinci-mcasp: Fix race condition during probe

by Joao Paulo Goncalves

From: Joao Paulo Goncalves <joao.goncalves(a)toradex.com> When using davinci-mcasp as CPU DAI with simple-card, there are some conditions that cause simple-card to finish registering a sound card before davinci-mcasp finishes registering all sound components. This creates a non-working sound card from userspace with no problem indication apart from not being able to play/record audio on a PCM stream. The issue arises during simultaneous probe execution of both drivers. Specifically, the simple-card driver, awaiting a CPU DAI, proceeds as soon as davinci-mcasp registers its DAI. However, this process can lead to the client mutex lock (client_mutex in soc-core.c) being held or davinci-mcasp being preempted before PCM DMA registration on davinci-mcasp finishes. This situation occurs when the probes of both drivers run concurrently. Below is the code path for this condition.

[PATCH v3 01/43] drm/fbdev-generic: Do not set physical framebuffer address

by Thomas Zimmermann

Framebuffer memory is allocated via vzalloc() from non-contiguous physical pages. The physical framebuffer start address is therefore meaningless. Do not set it. The value is not used within the kernel and only exported to userspace on dedicated ARM configs. No functional change is expected. v2: - refer to vzalloc() in commit message (Javier) Signed-off-by: Thomas Zimmermann <tzimmermann(a)suse.de> Fixes: a5b44c4adb16 ("drm/fbdev-generic: Always use shadow buffering") Cc: Thomas Zimmermann <tzimmermann(a)suse.de> Cc: Javier Martinez Canillas <javierm(a)redhat.com> Cc: Zack Rusin <zackr(a)vmware.com> Cc: Maarten Lankhorst <maarten.lankhorst(a)linux.intel.com> Cc: Maxime Ripard <mripard(a)kernel.org> Cc: <stable(a)vger.kernel.org> # v6.4+ Reviewed-by: Javier Martinez Canillas <javierm(a)redhat.com> Reviewed-by: Zack Rusin <zack.rusin(a)broadcom.com> Reviewed-by: Sui Jingfeng <sui.jingfeng(a)linux.dev> Tested-by: Sui Jingfeng <sui.jingfeng(a)linux.dev> Acked-by: Maxime Ripard <mripard(a)kernel.org> --- drivers/gpu/drm/drm_fbdev_generic.c | 1 - 1 file changed, 1 deletion(-) diff --git a/drivers/gpu/drm/drm_fbdev_generic.c b/drivers/gpu/drm/drm_fbdev_generic.c index be357f926faec..97e579c33d84a 100644 --- a/drivers/gpu/drm/drm_fbdev_generic.c +++ b/drivers/gpu/drm/drm_fbdev_generic.c @@ -113,7 +113,6 @@ static int drm_fbdev_generic_helper_fb_probe(struct drm_fb_helper *fb_helper, /* screen */ info->flags |= FBINFO_VIRTFB | FBINFO_READS_FAST; info->screen_buffer = screen_buffer; - info->fix.smem_start = page_to_phys(vmalloc_to_page(info->screen_buffer)); info->fix.smem_len = screen_size; /* deferred I/O */ -- 2.44.0

[PATCH] r8169: fix LED-related deadlock on module removal

by Heiner Kallweit

[ Upstream commit 19fa4f2a85d777a8052e869c1b892a2f7556569d ] Binding devm_led_classdev_register() to the netdev is problematic because on module unbinding we get a RTNL-related deadlock. Fix this by avoiding the device-managed LED functions. Note: We can safely call led_classdev_unregister() for a LED even if registering it failed, because led_classdev_unregister() detects this and is a no-op in this case. Fixes: 18764b883e15 ("r8169: add support for LED's on RTL8168/RTL8101") Cc: <stable(a)vger.kernel.org> # 6.8.x Reported-by: Lukas Wunner <lukas(a)wunner.de> Signed-off-by: Heiner Kallweit <hkallweit1(a)gmail.com> --- The original change was introduced with 6.8, 6.9 added support for LEDs on RTL8125.

It was discovered that RISCV architecture doesn't setup memblock corectly, leading to a page overlapping with PTR_ERR() being allocated, and subsequently crashing the kernel (link in Close: ) The reported crash has nothing to do with PTR_ERR(): the last page (at address 0xfffff000) being allocated leads to an unexpected arithmetic overflow in ext4; but still, this page shouldn't be allocated in the first place. Because PTR_ERR() is an architecture-independent thing, we shouldn't ask every single architecture to set this up. There may be other architectures beside RISCV that have the same problem. Fix this once and for all by reserving the physical memory page that may be mapped to the last virtual memory page as part of low memory. Unfortunately, this means if there is actual memory at this reserved location, that memory will become inaccessible. However, if this page is not reserved, it can only be accessed as high memory, so this doesn't matter if high memory is not supported. Even if high memory is supported, it is still only one page.

The issue also cropped up in the bug trackers of libguestfs [1] and the Red Hat bugzilla [2]. The problem is that when memcg is disabled with the boot time flag, the zswap shrinker might get called with sc->memcg == NULL. This is okay in many places, like the lruvec operations. But it crashes in memcg_page_state() - which is only used due to the non-node accounting of cgroup's the zswap memory to begin with. Nhat spotted that the memcg can be NULL in the memcg-disabled case, and I was then able to reproduce the crash locally as well.

[PATCH v2] net: usb: ax88179_178a: avoid writing the mac address before first reading

by Jose Ignacio Tornos Martinez

After the commit d2689b6a86b9 ("net: usb: ax88179_178a: avoid two consecutive device resets"), reset operation, in which the default mac address from the device is read, is not executed from bind operation and the random address, that is pregenerated just in case, is direclty written the first time in the device, so the default one from the device is not even read. This writing is not dangerous because is volatile and the default mac address is not missed. In order to avoid this and keep the simplification to have only one reset and reduce the delays, restore the reset from bind operation and remove the reset that is commanded from open operation. The behavior is the same but everything is ready for usbnet_probe. Tested with ASIX AX88179 USB Gigabit Ethernet devices. Restore the old behavior for the rest of possible devices because I don't have the hardware to test. cc: stable(a)vger.kernel.org # 6.6+ Fixes: d2689b6a86b9 ("net: usb: ax88179_178a: avoid two consecutive device resets") Reported-by: Jarkko Palviainen <jarkko.palviainen(a)gmail.com> Signed-off-by: Jose Ignacio Tornos Martinez <jtornosm(a)redhat.com> --- v2: - Restore reset from bind operation to avoid problems with usbnet_probe. v1: https://lore.kernel.org/netdev/20240410095603.502566-1-jtornosm@redhat.com/ drivers/net/usb/ax88179_178a.c | 4 ++-- 1 file changed, 2 insertions(+), 2 deletions(-) diff --git a/drivers/net/usb/ax88179_178a.c b/drivers/net/usb/ax88179_178a.c index 69169842fa2f..a493fde1af3f 100644 --- a/drivers/net/usb/ax88179_178a.c +++ b/drivers/net/usb/ax88179_178a.c @@ -1316,6 +1316,8 @@ static int ax88179_bind(struct usbnet *dev, struct usb_interface *intf) netif_set_tso_max_size(dev->net, 16384); + ax88179_reset(dev); + return 0; } @@ -1694,7 +1696,6 @@ static const struct driver_info ax88179_info = { .unbind = ax88179_unbind, .status = ax88179_status, .link_reset = ax88179_link_reset, - .reset = ax88179_reset, .stop = ax88179_stop, .flags = FLAG_ETHER | FLAG_FRAMING_AX, .rx_fixup = ax88179_rx_fixup, @@ -1707,7 +1708,6 @@ static const struct driver_info ax88178a_info = { .unbind = ax88179_unbind, .status = ax88179_status, .link_reset = ax88179_link_reset, - .reset = ax88179_reset, .stop = ax88179_stop, .flags = FLAG_ETHER | FLAG_FRAMING_AX, .rx_fixup = ax88179_rx_fixup, -- 2.44.0

[PATCH net] r8169: fix LED-related deadlock on module removal

by Heiner Kallweit

Binding devm_led_classdev_register() to the netdev is problematic because on module removal we get a RTNL-related deadlock. Fix this by avoiding the device-managed LED functions. Note: We can safely call led_classdev_unregister() for a LED even if registering it failed, because led_classdev_unregister() detects this and is a no-op in this case. Fixes: 18764b883e15 ("r8169: add support for LED's on RTL8168/RTL8101") Cc: <stable(a)vger.kernel.org> # 6.8.x Reported-by: Lukas Wunner <lukas(a)wunner.de> Signed-off-by: Heiner Kallweit <hkallweit1(a)gmail.com> --- The original change was introduced with 6.8, 6.9 added support for LEDs on RTL8125.

TBH, I think it's pretty convenient to have the drm_info in the TT just to make sure that when drivers request use_dma_alloc on SEV systems TT turns decryption on correctly, i.e. it's a nice sanity check when reading the logs. But if you'd prefer it in the driver I can move this logic there as well. z

[PATCH] binder: check offset alignment in binder_get_object()

by Carlos Llamas

Commit 6d98eb95b450 ("binder: avoid potential data leakage when copying txn") introduced changes to how binder objects are copied. In doing so, it unintentionally removed an offset alignment check done through calls to binder_alloc_copy_from_buffer() -> check_buffer(). These calls were replaced in binder_get_object() with copy_from_user(), so now an explicit offset alignment check is needed here. This avoids later complications when unwinding the objects gets harder. It is worth noting this check existed prior to commit 7a67a39320df ("binder: add function to copy binder object from buffer"), likely removed due to redundancy at the time.

He can resend if that helps with the process) Peng Fan also gave his reviewed-by in the v2 thread, it's always appreciable to get an ack from someone closer to the authors. Since the code itself is identical, I'll leave the decision to update or not up to you; I just can't unsee the "failue" in the summary :) Thanks! -- Dominique

v5.15+ backport request

by dcrady＠os.amperecomputing.com

Please backport the following v6.7 commit: commit be097997a273 ("KVM: arm64: Always invalidate TLB for stage-2 permission faults") to stable kernels v5.15 and newer to fix: It is possible for multiple vCPUs to fault on the same IPA and attempt to resolve the fault. One of the page table walks will actually update the PTE and the rest will return -EAGAIN per our race detection scheme. KVM elides the TLB invalidation on the racing threads as the return value is nonzero. Before commit a12ab1378a88 ("KVM: arm64: Use local TLBI on permission relaxation") KVM always used broadcast TLB invalidations when handling permission faults, which had the convenient property of making the stage-2 updates visible to all CPUs in the system. However now we do a local invalidation, and TLBI elision leads to the vCPU thread faulting again on the stale entry. Remember that the architecture permits the TLB to cache translations that precipitate a permission fault. Invalidate the TLB entry responsible for the permission fault if the stage-2 descriptor has been relaxed, regardless of which thread actually did the job. Thank you! doug rady

I'm not sure if you've missed this patch in mail box. :) The patch is pretty important as it lets the device tree (dts) decide whether to enable U3PHY or PCIe PHY. Because this is a shared hardware phy and could only be configured in dts to decide which function to be initialized, so it's something that should be included in the board-specific dts files. Do you think it needs to be resubmitted, or is it still in the queue for review? It's meant to be ready for action from kernel version 6.8 onwards. Looking forward to your thoughts on this. Let me know if there's anything else you need from my side. > Prior to this fix, the system would exhibit the following probe failure messages > for xhci1: > xhci-mtk 11290000.usb: supply vbus not found, using dummy regulator > xhci-mtk 11290000.usb: uwk - reg:0x400, version:104 > xhci-mtk 11290000.usb: xHCI Host Controller > xhci-mtk 11290000.usb: new USB bus registered, assigned bus number 5 > xhci-mtk 11290000.usb: clocks are not stable (0x1003d0f) > xhci-mtk 11290000.usb: can't setup: -110 > xhci-mtk 11290000.usb: USB bus 5 deregistered > xhci-mtk: probe of 11290000.usb failed with error -110 > > With the application of this dts fixup, the aforementioned initialization errors > are resolved and xhci1 is working. > > Signed-off-by: Macpaul Lin <macpaul.lin(a)mediatek.com> > --- > arch/arm64/boot/dts/mediatek/mt8395-genio-1200-evk.dts | 6 ++++++ > 1 file changed, 6 insertions(+) > > diff --git a/arch/arm64/boot/dts/mediatek/mt8395-genio-1200-evk.dts b/arch/arm64/boot/dts/mediatek/mt8395-genio-1200-evk.dts > index 7fc515a07c65..e0b9f2615c11 100644 > --- a/arch/arm64/boot/dts/mediatek/mt8395-genio-1200-evk.dts > +++ b/arch/arm64/boot/dts/mediatek/mt8395-genio-1200-evk.dts > @@ -854,6 +854,10 @@ > > &u3phy1 { > status = "okay"; > + > + u3port1: usb-phy@700 { > + mediatek,force-mode; > + }; > }; > > &u3phy2 { > @@ -885,6 +889,8 @@ > }; > > &xhci1 { > + phys = <&u2port1 PHY_TYPE_USB2>, > + <&u3port1 PHY_TYPE_USB3>; > vusb33-supply = <&mt6359_vusb_ldo_reg>; > status = "okay"; > }; Thanks Macpaul Lin

[PATCH v2 2/2] wifi: rtl8xxxu: enable MFP support with security flag of RX descriptor

by Martin Kaistra

In order to connect to networks which require 802.11w, add the MFP_CAPABLE flag and let mac80211 do the actual crypto in software.

[PATCH 2/2] wifi: rtl8xxxu: enable MFP support

In order to connect to networks which require 802.11w, add the MFP_CAPABLE flag and let mac80211 do the actual crypto in software.

[PATCH v2 0/2] usb: dwc3: Disable susphy during initialization

by Thinh Nguyen

We notice some platforms set "snps,dis_u3_susphy_quirk" and "snps,dis_u2_susphy_quirk" when they should not need to. Just make sure that the GUSB3PIPECTL.SUSPENDENABLE and GUSB2PHYCFG.SUSPHY are clear during initialization. The host initialization involved xhci. So the dwc3 needs to implement the xhci_plat_priv->plat_start() for xhci to re-enable the suspend bits. Since there's a prerequisite patch to drivers/usb/host/xhci-plat.h that's not a fix patch, this series should go on Greg's usb-testing branch instead of usb-linus.

Mike has a fix in that path for resv uncharge but it looks like the locking criteria was overlooked: hugetlb_cgroup_uncharge_folio_rsvd() will update the cgroup pointer, so it requires to be called with the lock held.

[PATCH] drm/xe/vm: prevent UAF in rebind_work_func()

by Matthew Auld

We flush the rebind worker during the vm close phase, however in places like preempt_fence_work_func() we seem to queue the rebind worker without first checking if the vm has already been closed. The concern here is the vm being closed with the worker flushed, but then being rearmed later, which looks like potential uaf, since there is no actual refcounting to track the queued worker. To ensure this can't happen prevent queueing the rebind worker once the vm has been closed.

[PATCH v2] PCI: dw-rockchip: Fix GPIO initialization flag

by Niklas Cassel

PERST is active low according to the PCIe specification. However, the existing pcie-dw-rockchip.c driver does: gpiod_set_value(..., 0); msleep(100); gpiod_set_value(..., 1); When asserting + deasserting PERST. This is of course wrong, but because all the device trees for this compatible string have also incorrectly marked this GPIO as ACTIVE_HIGH: $ git grep -B 10 reset-gpios arch/arm64/boot/dts/rockchip/rk3568* $ git grep -B 10 reset-gpios arch/arm64/boot/dts/rockchip/rk3588* The actual toggling of PERST is correct. (And we cannot change it anyway, since that would break device tree compatibility.) However, this driver does request the GPIO to be initialized as GPIOD_OUT_HIGH, which does cause a silly sequence where PERST gets toggled back and forth for no good reason. Fix this by requesting the GPIO to be initialized as GPIOD_OUT_LOW (which for this driver means PERST asserted). This will avoid an unnecessary signal change where PERST gets deasserted (by devm_gpiod_get_optional()) and then gets asserted (by rockchip_pcie_start_link()) just a few instructions later. Before patch, debug prints on EP side, when booting RC: [ 845.606810] pci: PERST asserted by host! [ 852.483985] pci: PERST de-asserted by host! [ 852.503041] pci: PERST asserted by host!

[PATCH v1] arm64: dts: imx8mm: fix missing pgc_vpu_* power domain parent

by Vitor Soares

[PATCH] random: handle creditable entropy from atomic process context

by Jason A. Donenfeld

The entropy accounting changes a static key when the RNG has initialized, since it only ever initializes once. Static key changes, however, cannot be made from atomic context, so depending on where the last creditable entropy comes from, the static key change might need to be deferred to a worker. Previously the code used the execute_in_process_context() helper function, which accounts for whether or not the caller is in_interrupt(). However, that doesn't account for the case where the caller is actually in process context but is holding a spinlock. This turned out to be the case with input_handle_event() in drivers/input/input.c contributing entropy: [<ffffffd613025ba0>] die+0xa8/0x2fc [<ffffffd613027428>] bug_handler+0x44/0xec [<ffffffd613016964>] brk_handler+0x90/0x144 [<ffffffd613041e58>] do_debug_exception+0xa0/0x148 [<ffffffd61400c208>] el1_dbg+0x60/0x7c [<ffffffd61400c000>] el1h_64_sync_handler+0x38/0x90 [<ffffffd613011294>] el1h_64_sync+0x64/0x6c [<ffffffd613102d88>] __might_resched+0x1fc/0x2e8 [<ffffffd613102b54>] __might_sleep+0x44/0x7c [<ffffffd6130b6eac>] cpus_read_lock+0x1c/0xec [<ffffffd6132c2820>] static_key_enable+0x14/0x38 [<ffffffd61400ac08>] crng_set_ready+0x14/0x28 [<ffffffd6130df4dc>] execute_in_process_context+0xb8/0xf8 [<ffffffd61400ab30>] _credit_init_bits+0x118/0x1dc [<ffffffd6138580c8>] add_timer_randomness+0x264/0x270 [<ffffffd613857e54>] add_input_randomness+0x38/0x48 [<ffffffd613a80f94>] input_handle_event+0x2b8/0x490 [<ffffffd613a81310>] input_event+0x6c/0x98 According to Guoyong, it's not really possible to refactor the various drivers to never hold a spinlock there. And in_atomic() isn't reliable. So, rather than trying to be too fancy, just punt the change in the static key to a workqueue always. There's basically no drawback of doing this, as the code already needed to account for the static key not changing immediately, and given that it's just an optimization, there's not exactly a hurry to change the static key right away, so deferal is fine.

[PATCH 2/2] serial: stm32: Reset .throttled state in .startup()

by Uwe Kleine-König

When an UART is opened that still has .throttled set from a previous open, the RX interrupt is enabled but the irq handler doesn't consider it. This easily results in a stuck irq with the effect to occupy the CPU in a tight loop. So reset the throttle state in .startup() to ensure that RX irqs are handled.

[PATCH 1/2] serial: stm32: Return IRQ_NONE in the ISR if no handling happend

by Uwe Kleine-König

If there is a stuck irq that the handler doesn't address, returning IRQ_HANDLED unconditionally makes it impossible for the irq core to detect the problem and disable the irq. So only return IRQ_HANDLED if an event was handled. A stuck irq is still problematic, but with this change at least it only makes the UART nonfunctional instead of occupying the (usually only) CPU by 100% and so stall the whole machine.

[PATCH] net: usb: ax88179_178a: avoid writing the mac address before first reading

by Jose Ignacio Tornos Martinez

After the commit d2689b6a86b9 ("net: usb: ax88179_178a: avoid two consecutive device resets"), reset operation, in which the default mac address from the device is read, is not executed from bind operation and the random address, that is pregenerated just in case, is direclty written the first time in the device, so the default one from the device is not even read. This writing is not dangerous because is volatile and the default mac address is not missed. In order to avoid this, do not allow writing a mac address directly into the device, if the default mac address from the device has not been read yet. cc: stable(a)vger.kernel.org # 6.6+ Fixes: d2689b6a86b9 ("net: usb: ax88179_178a: avoid two consecutive device resets") Reported-by: Jarkko Palviainen <jarkko.palviainen(a)gmail.com> Signed-off-by: Jose Ignacio Tornos Martinez <jtornosm(a)redhat.com> --- drivers/net/usb/ax88179_178a.c | 8 ++++++++ 1 file changed, 8 insertions(+) diff --git a/drivers/net/usb/ax88179_178a.c b/drivers/net/usb/ax88179_178a.c index 69169842fa2f..650bb7b6badf 100644 --- a/drivers/net/usb/ax88179_178a.c +++ b/drivers/net/usb/ax88179_178a.c @@ -174,6 +174,7 @@ struct ax88179_data { u32 wol_supported; u32 wolopts; u8 disconnecting; + u8 mac_address_read; }; struct ax88179_int_data { @@ -969,9 +970,12 @@ static int ax88179_change_mtu(struct net_device *net, int new_mtu) static int ax88179_set_mac_addr(struct net_device *net, void *p) { struct usbnet *dev = netdev_priv(net); + struct ax88179_data *ax179_data = dev->driver_priv; struct sockaddr *addr = p; int ret; + if (!ax179_data->mac_address_read) + return -EAGAIN; if (netif_running(net)) return -EBUSY; if (!is_valid_ether_addr(addr->sa_data)) @@ -1256,6 +1260,7 @@ static int ax88179_led_setting(struct usbnet *dev) static void ax88179_get_mac_addr(struct usbnet *dev) { + struct ax88179_data *ax179_data = dev->driver_priv; u8 mac[ETH_ALEN]; memset(mac, 0, sizeof(mac)); @@ -1281,6 +1286,9 @@ static void ax88179_get_mac_addr(struct usbnet *dev) ax88179_write_cmd(dev, AX_ACCESS_MAC, AX_NODE_ID, ETH_ALEN, ETH_ALEN, dev->net->dev_addr); + + ax179_data->mac_address_read = 1; + netdev_info(dev->net, "MAC address: %pM\n", dev->net->dev_addr); } static int ax88179_bind(struct usbnet *dev, struct usb_interface *intf) -- 2.44.0

[Request] backport a mainline patch to Linux kernel-5.10 stable tree

by Bo Ye (叶波)

Dear Reviewers, we suggest to backport a commit to Linux kernel-5.10 stable tree to fix thermal bug. Thanks a lot source patch: https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/d… thermal: core: Fix thermal zone suspend-resume synchronization There are 3 synchronization issues with thermal zone suspend-resume during system-wide transitions: 1. The resume code runs in a PM notifier which is invoked after user space has been thawed, so it can run concurrently with user space which can trigger a thermal zone device removal. If that happens, the thermal zone resume code may use a stale pointer to the next list element and crash, because it does not hold thermal_list_lock while walking thermal_tz_list. 2. The thermal zone resume code calls thermal_zone_device_init() outside the zone lock, so user space or an update triggered by the platform firmware may see an inconsistent state of a thermal zone leading to unexpected behavior. 3. Clearing the in_suspend global variable in thermal_pm_notify() allows __thermal_zone_device_update() to continue for all thermal zones and it may as well run before the thermal_tz_list walk (or at any point during the list walk for that matter) and attempt to operate on a thermal zone that has not been resumed yet. It may also race destructively with thermal_zone_device_init(). To address these issues, add thermal_list_lock locking to thermal_pm_notify(), especially arount the thermal_tz_list, make it call thermal_zone_device_init() back-to-back with __thermal_zone_device_update() under the zone lock and replace in_suspend with per-zone bool "suspend" indicators set and unset under the given zone's lock.
