FAILED: patch "[PATCH] media: dvb-core: Fix UAF due to refcount races at releasing" failed to apply to 4.9-stable tree

The patch below does not apply to the 4.9-stable tree. If someone wants it applied there, or to any other stable or longterm tree, then please email the backport, including the original git commit id to <stable(a)vger.kernel.org>. Possible dependencies: fd3d91ab1c6a ("media: dvb-core: Fix UAF due to refcount races at releasing") thanks, greg k-h ------------------ original commit in Linus's tree ------------------ From fd3d91ab1c6ab0628fe642dd570b56302c30a792 Mon Sep 17 00:00:00 2001 From: Takashi Iwai <tiwai(a)suse.de> Date: Mon, 31 Oct 2022 11:02:45 +0100 Subject: [PATCH] media: dvb-core: Fix UAF due to refcount races at releasing The dvb-core tries to sync the releases of opened files at dvb_dmxdev_release() with two refcounts: dvbdev->users and dvr_dvbdev->users. A problem is present in those two syncs: when yet another dvb_demux_open() is called during those sync waits, dvb_demux_open() continues to process even if the device is being closed. This includes the increment of the former refcount, resulting in the leftover refcount after the sync of the latter refcount at dvb_dmxdev_release(). It ends up with use-after-free, since the function believes that all usages were gone and releases the resources. This patch addresses the problem by adding the check of dmxdev->exit flag at dvb_demux_open(), just like dvb_dvr_open() already does. With the exit flag check, the second call of dvb_demux_open() fails, hence the further corruption can be avoided. Also for avoiding the races of the dmxdev->exit flag reference, this patch serializes the dmxdev->exit set up and the sync waits with the dmxdev->mutex lock at dvb_dmxdev_release(). Without the mutex lock, dvb_demux_open() (or dvb_dvr_open()) may run concurrently with dvb_dmxdev_release(), which allows to skip the exit flag check and continue the open process that is being closed. CVE-2022-41218 is assigned to those bugs above.

Basically, starts with alphabetic or underline, and then the rest of the characters have alpha-numeric or underline in them. But system names do not have any true naming conventions, as they are created by the TRACE_SYSTEM macro and nothing tests to see what they are. The "xhci-hcd" trace events has a '-' in the system name.

Basically, starts with alphabetic or underline, and then the rest of the characters have alpha-numeric or underline in them. But system names do not have any true naming conventions, as they are created by the TRACE_SYSTEM macro and nothing tests to see what they are. The "xhci-hcd" trace events has a '-' in the system name. When trying to attach a eprobe to one of these trace points, it fails because the system name does not follow the variable naming convention because of the hyphen, and the eprobe checks fail on this.

This fixes a bug where saving/restoring, i.e. migrating, a vCPU will fail if WAITPKG (the associated CPUID feature) is enabled for the vCPU, and obviously allows L1 to enable the feature for L2. KVM already effectively exposes ENABLE_USR_WAIT_PAUSE to L1 by stuffing the allowed-1 control ina vCPU's virtual MSR_IA32_VMX_PROCBASED_CTLS2 when updating secondary controls in response to KVM_SET_CPUID(2), but (a) that depends on flawed code (KVM shouldn't touch VMX MSRs in response to CPUID updates) and (b) runs afoul of vmx_restore_control_msr()'s restriction that the guest value must be a strict subset of the supported host value. Although no past commit explicitly enabled nested support for WAITPKG, doing so is safe and functionally correct from an architectural perspective as no additional KVM support is needed to virtualize TPAUSE, UMONITOR, and UMWAIT for L2 relative to L1, and KVM already forwards VM-Exits to L1 as necessary (commit bf653b78f960, "KVM: vmx: Introduce handle_unexpected_vmexit and handle WAITPKG vmexit"). Note, KVM always keeps the hosts MSR_IA32_UMWAIT_CONTROL resident in hardware, i.e. always runs both L1 and L2 with the host's power management settings for TPAUSE and UMWAIT.

FAILED: patch "[PATCH] perf probe: Fix to get the DW_AT_decl_file and" failed to apply to 4.9-stable tree

by gregkh＠linuxfoundation.org

The patch below does not apply to the 4.9-stable tree. If someone wants it applied there, or to any other stable or longterm tree, then please email the backport, including the original git commit id to <stable(a)vger.kernel.org>. Possible dependencies: a9dfc46c67b5 ("perf probe: Fix to get the DW_AT_decl_file and DW_AT_call_file as unsinged data") f828929ab7f0 ("perf probe: Use dwarf_attr_integrate as generic DWARF attr accessor") thanks, greg k-h ------------------ original commit in Linus's tree ------------------ From a9dfc46c67b52ad43b8e335e28f4cf8002c67793 Mon Sep 17 00:00:00 2001 From: "Masami Hiramatsu (Google)" <mhiramat(a)kernel.org> Date: Sat, 5 Nov 2022 12:01:14 +0900 Subject: [PATCH] perf probe: Fix to get the DW_AT_decl_file and DW_AT_call_file as unsinged data DWARF version 5 standard Sec 2.14 says that Any debugging information entry representing the declaration of an object, module, subprogram or type may have DW_AT_decl_file, DW_AT_decl_line and DW_AT_decl_column attributes, each of whose value is an unsigned integer constant. So it should be an unsigned integer data. Also, even though the standard doesn't clearly say the DW_AT_call_file is signed or unsigned, the elfutils (eu-readelf) interprets it as unsigned integer data and it is natural to handle it as unsigned integer data as same as DW_AT_decl_file. This changes the DW_AT_call_file as unsigned integer data too.

So it should be an unsigned integer data. Also, even though the standard doesn't clearly say the DW_AT_call_file is signed or unsigned, the elfutils (eu-readelf) interprets it as unsigned integer data and it is natural to handle it as unsigned integer data as same as DW_AT_decl_file. This changes the DW_AT_call_file as unsigned integer data too.

So, shrinker will be unregistered and registered, which could down write shrinker_rwsem under pmd_write_lock.

Here the section related to CONFIG_MPTCP was quite short but the next commit needs to add more code around. It is then cleaner to move specific MPTCP code to functions located in net/mptcp directory. Now that mptcp_subflow_request_sock_ops structure can be static, it can also be marked as "read only after init".

It should then not be used with MPTCP subflows on top of IPv6. For example, it contains the 'family' field, initialised to AF_INET. This 'family' field is used by TCP FastOpen code to generate the cookie but also by TCP Metrics, SELinux and SYN Cookies. Using the wrong family will not lead to crashes but displaying/using/checking wrong things. Note that 'send_reset' callback from request_sock_ops structure is used in some error paths. It is then also important to use the correct one for IPv4 or IPv6. The slab name can also be different in IPv4 and IPv6, it will be used when printing some log messages. The slab pointer will anyway be the same because the object size is the same for both v4 and v6. A BUILD_BUG_ON() has also been added to make sure this size is the same.

FAILED: patch "[PATCH] mptcp: dedicated request sock for subflow in v6" failed to apply to 5.15-stable tree

The patch below does not apply to the 5.15-stable tree.

It should then not be used with MPTCP subflows on top of IPv6. For example, it contains the 'family' field, initialised to AF_INET. This 'family' field is used by TCP FastOpen code to generate the cookie but also by TCP Metrics, SELinux and SYN Cookies. Using the wrong family will not lead to crashes but displaying/using/checking wrong things. Note that 'send_reset' callback from request_sock_ops structure is used in some error paths. It is then also important to use the correct one for IPv4 or IPv6. The slab name can also be different in IPv4 and IPv6, it will be used when printing some log messages. The slab pointer will anyway be the same because the object size is the same for both v4 and v6. A BUILD_BUG_ON() has also been added to make sure this size is the same.

For example: 1. The device driver assigned the devfreq governor to simple_ondemand by the function devfreq_add_device() and init the devfreq member void *data to a pointer of a static structure devfreq_simple_ondemand_data by the function devfreq_add_device(). 2. The user changed the devfreq governor to userspace by the command "echo userspace > /sys/class/devfreq/.../governor". 3. The governor userspace alloced a dynamic memory for the struct userspace_data and assigend the member void *data of devfreq to this memory by the function userspace_init(). 4. The user changed the devfreq governor back to simple_ondemand by the command "echo simple_ondemand > /sys/class/devfreq/.../governor". 5. The governor userspace exited and assigned the member void *data in the structure devfreq to NULL by the function userspace_exit(). 6. The governor simple_ondemand fetched the static information of devfreq_simple_ondemand_data in the function devfreq_simple_ondemand_func() but the member void *data of devfreq was assigned to NULL by the function userspace_exit(). 7. The information of upthreshold and downdifferential is lost and the governor simple_ondemand can't work correctly. The member void *data in the structure devfreq is designed for a static pointer used in a governor and inited by the function devfreq_add_device(). This patch add an element named governor_data in the devfreq structure which can be used by a governor(E.g userspace) who want to assign a private data to do some private things.

FAILED: patch "[PATCH] x86/MCE/AMD: Clear DFR errors found in THR handler" failed to apply to 5.15-stable tree

Possible dependencies: bc1b705b0eee ("x86/MCE/AMD: Clear DFR errors found in THR handler") 8121b8f947be ("x86/mce: Get rid of msr_ops") thanks, greg k-h ------------------ original commit in Linus's tree ------------------ From bc1b705b0eee4c645ad8b3bbff3c8a66e9688362 Mon Sep 17 00:00:00 2001 From: Yazen Ghannam <yazen.ghannam(a)amd.com> Date: Tue, 21 Jun 2022 15:59:43 +0000 Subject: [PATCH] x86/MCE/AMD: Clear DFR errors found in THR handler AMD's MCA Thresholding feature counts errors of all severity levels, not just correctable errors. If a deferred error causes the threshold limit to be reached (it was the error that caused the overflow), then both a deferred error interrupt and a thresholding interrupt will be triggered. The order of the interrupts is not guaranteed. If the threshold interrupt handler is executed first, then it will clear MCA_STATUS for the error. It will not check or clear MCA_DESTAT which also holds a copy of the deferred error. When the deferred error interrupt handler runs it will not find an error in MCA_STATUS, but it will find the error in MCA_DESTAT. This will cause two errors to be logged. Check for deferred errors when handling a threshold interrupt. If a bank contains a deferred error, then clear the bank's MCA_DESTAT register. Define a new helper function to do the deferred error check and clearing of MCA_DESTAT.

This means we could have garbage in the parent color. I don't know what the ramifications are of that, but it's probably not great, so fix this by initializing parent to NULL. I spot checked all of our other usages in btrfs and we appear to be doing the correct thing everywhere else.

Possible dependencies: 45ae272a948a ("clocksource/drivers/arm_arch_timer: Fix XGene-1 TVAL register math error") thanks, greg k-h ------------------ original commit in Linus's tree ------------------ From 45ae272a948a03a7d55748bf52d2f47d3b4e1d5a Mon Sep 17 00:00:00 2001 From: Joe Korty <joe.korty(a)concurrent-rt.com> Date: Mon, 21 Nov 2022 14:53:43 +0000 Subject: [PATCH] clocksource/drivers/arm_arch_timer: Fix XGene-1 TVAL register math error The TVAL register is 32 bit signed. Thus only the lower 31 bits are available to specify when an interrupt is to occur at some time in the near future. Attempting to specify a larger interval with TVAL results in a negative time delta which means the timer fires immediately upon being programmed, rather than firing at that expected future time. The solution is for Linux to declare that TVAL is a 31 bit register rather than give its true size of 32 bits. This prevents Linux from programming TVAL with a too-large value. Note that, prior to 5.16, this little trick was the standard way to handle TVAL in Linux, so there is nothing new happening here on that front. The softlockup detector hides the issue, because it keeps generating short timer deadlines that are within the scope of the broken timer. Disable it, and you start using NO_HZ with much longer timer deadlines, which turns into an interrupt flood: 11: 1124855130 949168462 758009394 76417474 104782230 30210281 310890 1734323687 GICv2 29 Level arch_timer And "much longer" isn't that long: it takes less than 43s to underflow TVAL at 50MHz (the frequency of the counter on XGene-1). Some comments on the v1 version of this patch by Marc Zyngier: XGene implements CVAL (a 64bit comparator) in terms of TVAL (a countdown register) instead of the other way around. TVAL being a 32bit register, the width of the counter should equally be 32. However, TVAL is a *signed* value, and keeps counting down in the negative range once the timer fires. It means that any TVAL value with bit 31 set will fire immediately, as it cannot be distinguished from an already expired timer. Reducing the timer range back to a paltry 31 bits papers over the issue. Another problem cannot be fixed though, which is that the timer interrupt *must* be handled within the negative countdown period, or the interrupt will be lost (TVAL will rollover to a positive value, indicative of a new timer deadline).

The series is intended for stable(a)vger.kernel.org # 5.4+ Syzkaller reported the following bug on linux-5.{4, 10, 15}.y: https://syzkaller.appspot.com/bug?id=ce5575575f074c33ff80d104f5baee26f22e95… The upstream commit that introduces this bug is: 1ed1d5921139 ("net: skip virtio_net_hdr_set_proto if protocol already set") Upstream fixes the bug with the following commits, one of which introduces new support: e9d3f80935b6 ("net/af_packet: make sure to pull mac header") dfed913e8b55 ("net/af_packet: add VLAN support for AF_PACKET SOCK_RAW GSO") The additional logic and risk backported seems manageable. The blammed commit introduces a kernel BUG in __skb_gso_segment for AF_PACKET SOCK_RAW GSO VLAN tagged packets. What happens is that virtio_net_hdr_set_proto() exists early as skb->protocol is already set to ETH_P_ALL. Then in packet_parse_headers() skb->protocol is set to ETH_P_8021AD, but neither the network header position is adjusted, nor the mac header is pulled. Thus when we get to validate the xmit skb and enter skb_mac_gso_segment(), skb->mac_len has value 14, but vlan_depth gets updated to 18 after skb_network_protocol() is called. This causes the BUG_ON from __skb_pull(skb, vlan_depth) to be hit, as the mac header has not been pulled yet. The fixes from upstream backported cleanly without conflicts. I updated the commit message of the first patch to describe the problem encountered, and added Cc, Fixes, Reported-by and Tested-by tags. For the second patch I just added Cc to stable indicating the versions to be fixed, and added my Tested and Signed-off-by tags. I tested the patches on linux-5.{4, 10, 15}.y.

The same problem does not occur on x86-64 and he also reported that converting sb->s_inode_wblist_lock to raw_spinlock_t makes the problem disappear indicating that the RT spinlock variant is the problem. Which in turn means that RT mutexes on ARM64 and any other weakly ordered architecture are affected by this independent of RT. Will Deacon observed: "I'd be more inclined to be suspicious of the slowpath tbh, as we need to make sure that we have acquire semantics on all paths where the lock can be taken. Looking at the rtmutex code, this really isn't obvious to me -- for example, try_to_take_rt_mutex() appears to be able to return via the 'takeit' label without acquire semantics and it looks like we might be relying on the caller's subsequent _unlock_ of the wait_lock for ordering, but that will give us release semantics which aren't correct." Sebastian Andrzej Siewior prototyped a fix that does work based on that comment but it was a little bit overkill and added some fences that should not be necessary. The lock owner is updated with an IRQ-safe raw spinlock held, but the spin_unlock does not provide acquire semantics which are needed when acquiring a mutex. Adds the necessary acquire semantics for lock owner updates in the slow path acquisition and the waiter bit logic. It successfully completed 10 iterations of the dbench workload while the vanilla kernel fails on the first iteration.

This fixes the recent regression caused by the backport of 39bd801d6908. e8444560b4d9302a511f0996f4cfdf85b628f4ca ASoC/SoundWire: dai: expand 'stream' concept beyond SoundWire 636110411ca726f19ef8e87b0be51bb9a4cdef06 ASoC: Intel/SOF: use set_stream() instead of set_tdm_slots() for HDAudio Thanks!

[PATCH v2] crypto: ccp - Allocate TEE ring and cmd buffer using DMA APIs

by Rijo Thomas

For AMD Secure Processor (ASP) to map and access TEE ring buffer, the ring buffer address sent by host to ASP must be a real physical address and the pages must be physically contiguous. In a virtualized environment though, when the driver is running in a guest VM, the pages allocated by __get_free_pages() may not be contiguous in the host (or machine) physical address space. Guests will see a guest (or pseudo) physical address and not the actual host (or machine) physical address. The TEE running on ASP cannot decipher pseudo physical addresses. It needs host or machine physical address. To resolve this problem, use DMA APIs for allocating buffers that must be shared with TEE. This will ensure that the pages are contiguous in host (or machine) address space. If the DMA handle is an IOVA, translate it into a physical address before sending it to ASP. This patch also exports two APIs (one for buffer allocation and another to free the buffer). This API can be used by AMD-TEE driver to share buffers with TEE.

Missing 6.0/6.1 stable patch

by Limonciello, Mario

[Public] Hi, This below patch from 6.2-rc1 was Cc to stable 6.0/6.1: afa6646b1c5d ("drm/amdgpu: skip MES for S0ix as well since it's part of GFX") However It didn't get picked up for 6.0.16 or 6.1.2. I also didn't see it in stable-queue.git/tree/queue-6.0 or stable-queue.git/tree/queue-6.1. I double checked and it works on both 6.0.y and 6.1.y, and It fixes a bad suspend problem, so I wanted to double check it didn't get missed with the holiday shuffle. Thanks!

[PATCH] of/fdt: run soc memory setup when early_init_dt_scan_memory fails

by andreas＠rammhold.de

From: Andreas Rammhold <andreas(a)rammhold.de> If memory has been found early_init_dt_scan_memory now returns 1. If it hasn't found any memory it will return 0, allowing other memory setup mechanisms to carry on. Previously early_init_dt_scan_memory always returned 0 without distinguishing between any kind of memory setup being done or not. Any code path after the early_init_dt_scan memory call in the ramips plat_mem_setup code wouldn't be executed anymore. Making early_init_dt_scan_memory the only way to initialize the memory. Some boards, including my mt7621 based Cudy X6 board, depend on memory initialization being done via the soc_info.mem_detect function pointer. Those wouldn't be able to obtain memory and panic the kernel during early bootup with the message "early_init_dt_alloc_memory_arch: Failed to allocate 12416 bytes align=0x40".

Senhorita Michelle

by Michelle family

PROCURANDO SUA AJUDA sincero e honesto como você, que possa me ajudar neste momento de necessidade, durante a crise civil e política em nosso país, meus pais e minhas três irmãs foram envenenados pela crueldade. Felizmente para mim, eu estava na escola quando essa tragédia aconteceu com minha família. Por falar nisso. No momento, ainda estou aqui no país, mas muito inseguro para mim. Estou vivendo com muito medo e escravidão. Pretendo deixar este país o mais rápido possível, mas apenas uma coisa me atrapalhou. Meu falecido pai depositou uma quantia em dinheiro de 3,2 milhões de euros em uma das principais instituições da Europa para transferir Infelizmente, porém, ele não concluiu a transação até morrer repentinamente. 45% pela ajuda e assistência, porque acho estúpido tentar confiar em um total desconhecido que nunca conheci antes. Estou instintivamente convencido de que você é uma pessoa honesta e tem a capacidade de lidar com essa transação comigo. Quando estiver pronto, vou encontrá-lo e passar o resto da minha vida em seu país. Estou com medo aqui porque os inimigos dos meus pais, tios e parentes ruins estão atrás de mim. Por favor, deixe-me saber o que você acha da minha proposta para você. Miss Michelle

[PATCH v4 01/27] drm/amd: Delay removal of the firmware framebuffer

by Mario Limonciello

Removing the firmware framebuffer from the driver means that even if the driver doesn't support the IP blocks in a GPU it will no longer be functional after the driver fails to initialize. This change will ensure that unsupported IP blocks at least cause the driver to work with the EFI framebuffer.

[PATCH] torture: Fix hang during kthread shutdown phase

by Joel Fernandes (Google)

During shutdown of rcutorture, the shutdown thread in rcu_torture_cleanup() calls torture_cleanup_begin() which sets fullstop to FULLSTOP_RMMOD. This is enough to cause the rcutorture threads for readers and fakewriters to breakout of their main while loop and start shutting down. Once out of their main loop, they then call torture_kthread_stopping() which in turn waits for kthread_stop() to be called, however rcu_torture_cleanup() has not even called kthread_stop() on those threads yet, it does that a bit later. However, before it gets a chance to do so, torture_kthread_stopping() calls schedule_timeout_interruptible(1) in a tight loop. Tracing confirmed this makes the timer softirq constantly execute timer callbacks, while never returning back to the softirq exit path and is essentially "locked up" because of that. If the softirq preempts the shutdown thread, kthread_stop() may never be called. This commit improves the situation dramatically, by increasing timeout passed to schedule_timeout_interruptible() 1/20th of a second. This causes the timer softirq to not lock up a CPU and everything works fine. Testing has shown 100 runs of TREE07 passing reliably, which was not the case before because of RCU stalls.

[PATCH AUTOSEL 6.1 01/10] io_uring/cancel: re-grab ctx mutex after finishing wait

by Sasha Levin

From: Jens Axboe <axboe(a)kernel.dk> [ Upstream commit 23fffb2f09ce1145cbd751801d45ba74acaa6542 ] If we have a signal pending during cancelations, it'll cause the task_work run to return an error. Since we didn't run task_work, the current task is left in TASK_INTERRUPTIBLE state when we need to re-grab the ctx mutex, and the kernel will rightfully complain about that. Move the lock grabbing for the error cases outside the loop to avoid that issue.

[PATCH v3 stable 4.19 1/2] mm/khugepaged: fix GUP-fast interaction by sending IPI

by Jann Horn

Since commit 70cbc3cc78a99 ("mm: gup: fix the fast GUP race against THP collapse"), the lockless_pages_from_mm() fastpath rechecks the pmd_t to ensure that the page table was not removed by khugepaged in between. However, lockless_pages_from_mm() still requires that the page table is not concurrently freed. Fix it by sending IPIs (if the architecture uses semi-RCU-style page table freeing) before freeing/reusing page tables.

[PATCH v2] nvmem: core: Fix race in nvmem_register()

by Hector Martin

nvmem_register() currently registers the device before adding the nvmem cells, which creates a race window where consumers may find the nvmem device (and not get PROBE_DEFERred), but then fail to find the cells and error out. Move device registration to the end of nvmem_register(), to close the race.

[PATCH] comedi: adv_pci1760: Fix PWM instruction handling

by Ian Abbott

(Actually, this is fixing the "Read the Current Status" command sent to the device's outgoing mailbox, but it is only currently used for the PWM instructions.) The PCI-1760 is operated mostly by sending commands to a set of Outgoing Mailbox registers, waiting for the command to complete, and reading the result from the Incoming Mailbox registers. One of these commands is the "Read the Current Status" command. The number of this command is 0x07 (see the User's Manual for the PCI-1760 at <https://advdownload.advantech.com/productfile/Downloadfile2/1-11P6653/PCI-1…>. The `PCI1760_CMD_GET_STATUS` macro defined in the driver should expand to this command number 0x07, but unfortunately it currently expands to 0x03. (Command number 0x03 is not defined in the User's Manual.) Correct the definition of the `PCI1760_CMD_GET_STATUS` macro to fix it. This is used by all the PWM subdevice related instructions handled by `pci1760_pwm_insn_config()` which are probably all broken. The effect of sending the undefined command number 0x03 is not known.

[PATCH v2 stable 4.19 1/2] mm/khugepaged: fix GUP-fast interaction by sending IPI

by Jann Horn

Since commit 70cbc3cc78a99 ("mm: gup: fix the fast GUP race against THP collapse"), the lockless_pages_from_mm() fastpath rechecks the pmd_t to ensure that the page table was not removed by khugepaged in between. However, lockless_pages_from_mm() still requires that the page table is not concurrently freed. Fix it by sending IPIs (if the architecture uses semi-RCU-style page table freeing) before freeing/reusing page tables.

[PATCH] VMCI: Use threaded irqs instead of tasklets

From: Vishnu Dasa <vdasa(a)vmware.com> The vmci_dispatch_dgs() tasklet function calls vmci_read_data() which uses wait_event() resulting in invalid sleep in an atomic context (and therefore potentially in a deadlock).

[PATCH] x86/kexec: fix double vfree of image->elf_headers

by Vlastimil Babka

An investigation of a "Trying to vfree() nonexistent vm area" bug occurring in arch_kimage_file_post_load_cleanup() doing a vfree(image->elf_headers) in our 5.14-based kernel yielded the following double vfree() scenario, also present in mainline: SYSCALL_DEFINE5(kexec_file_load) kimage_file_alloc_init() kimage_file_prepare_segments() arch_kexec_kernel_image_probe() kexec_image_load_default() kexec_bzImage64_ops.load() bzImage64_load() crash_load_segments() prepare_elf_headers(image, &kbuf.buffer, &kbuf.bufsz); image->elf_headers = kbuf.buffer; ret = kexec_add_buffer(&kbuf); if (ret) vfree((void *)image->elf_headers); // first vfree() if (ret) kimage_file_post_load_cleanup() vfree(image->elf_headers); // second vfree() AFAICS the scenario is possible since v5.19 commit b3e34a47f989 ("x86/kexec: fix memory leak of elf header buffer") that was marked for stable and also was backported to our kernel. Fix the problem by setting the pointer to NULL after the first vfree(). Also set elf_headers_sz to 0, as kimage_file_post_load_cleanup() does.

[PATCH v2 1/3] KVM: arm64: Fix S1PTW handling on RO memslots

by Marc Zyngier

A recent development on the EFI front has resulted in guests having their page tables baked in the firmware binary, and mapped into the IPA space as part of a read-only memslot. Not only is this legitimate, but it also results in added security, so thumbs up. It is possible to take an S1PTW translation fault if the S1 PTs are unmapped at stage-2. However, KVM unconditionally treats S1PTW as a write to correctly handle hardware AF/DB updates to the S1 PTs. Furthermore, KVM injects an exception into the guest for S1PTW writes. In the aforementioned case this results in the guest taking an abort it won't recover from, as the S1 PTs mapping the vectors suffer from the same problem. So clearly our handling is... wrong. Instead, switch to a two-pronged approach: - On S1PTW translation fault, handle the fault as a read - On S1PTW permission fault, handle the fault as a write This is of no consequence to SW that *writes* to its PTs (the write will trigger a non-S1PTW fault), and SW that uses RO PTs will not use HW-assisted AF/DB anyway, as that'd be wrong. Only in the case described in c4ad98e4b72c ("KVM: arm64: Assume write fault on S1PTW permission fault on instruction fetch") do we end-up with two back-to-back faults (page being evicted and faulted back). I don't think this is a case worth optimising for.

[PATCH 1/1] serial: pch_uart: Pass correct sg to dma_unmap_sg()

by Ilpo Järvinen

A local variable sg is used to store scatterlist pointer in pch_dma_tx_complete(). The for loop doing Tx byte accounting before dma_unmap_sg() alters sg in its increment statement. Therefore, the pointer passed into dma_unmap_sg() won't match to the one given to dma_map_sg(). To fix the problem, use priv->sg_tx_p directly in dma_unmap_sg() instead of the local variable.

5.15-stable io_uring backport

by Jens Axboe

Hi Greg, Here's the series we discussed before the break, no changes since then. Last 3 patches are new stable backports, the rest is backporting the 5.15.85 io_uring codebase to 5.10-stable. This is done to make 5.10 maintainable wrt io_uring, and importantly, to bring back the native io workers to 5.10-stable. -- Jens Axboe

[PATCH v2] usb: xhci: Check endpoint is valid before dereferencing it

by Jimmy Hu

When the host controller is not responding, all URBs queued to all endpoints need to be killed. This can cause a kernel panic if we dereference an invalid endpoint. Fix this by using xhci_get_virt_ep() helper to find the endpoint and checking if the endpoint is valid before dereferencing it.

[PATCH] matroxfb: G200eW: Increase max memory from 1 MB to 16 MB

by Paul Menzel

Commit 62d89a7d49af ("video: fbdev: matroxfb: set maxvram of vbG200eW to the same as vbG200 to avoid black screen") accidently decreases the maximum memory size for the Matrox G200eW (102b:0532) from 8 MB to 1 MB by missing one zero. This caused the driver initialization to fail with the messages below, as the minimum required VRAM size is 2 MB: [ 9.436420] matroxfb: Matrox MGA-G200eW (PCI) detected [ 9.444502] matroxfb: cannot determine memory size [ 9.449316] matroxfb: probe of 0000:0a:03.0 failed with error -1 So, add the missing 0 to make it the intended 16 MB. Successfully tested on the Dell PowerEdge R910/0KYD3D, BIOS 2.10.0 08/29/2013, that the warning is gone. While at it, add a leading 0 to the maxdisplayable entry, so it’s aligned properly. The value could probably also be increased from 8 MB to 16 MB, as the G200 uses the same values, but I have not checked any datasheet. Note, matroxfb is obsolete and superseded by the maintained DRM driver mga200, which is used by default on most systems where both drivers are available. Therefore, on most systems it was only a cosmetic issue.

[PATCH v6] media: uvcvideo: Fix race condition with usb_kill_urb

by Ricardo Ribalda

usb_kill_urb warranties that all the handlers are finished when it returns, but does not protect against threads that might be handling asynchronously the urb. For UVC, the function uvc_ctrl_status_event_async() takes care of control changes asynchronously. If the code is executed in the following order: CPU 0 CPU 1 ===== ===== uvc_status_complete() uvc_status_stop() uvc_ctrl_status_event_work() uvc_status_start() -> FAIL Then uvc_status_start will keep failing and this error will be shown: <4>[ 5.540139] URB 0000000000000000 submitted while active drivers/usb/core/urb.c:378 usb_submit_urb+0x4c3/0x528 Let's improve the current situation, by not re-submiting the urb if we are stopping the status event. Also process the queued work (if any) during stop. CPU 0 CPU 1 ===== ===== uvc_status_complete() uvc_status_stop() uvc_status_start() uvc_ctrl_status_event_work() -> FAIL Hopefully, with the usb layer protection this should be enough to cover all the cases.

[PATCH v5] media: uvcvideo: Fix race condition with usb_kill_urb

by Ricardo Ribalda

usb_kill_urb warranties that all the handlers are finished when it returns, but does not protect against threads that might be handling asynchronously the urb. For UVC, the function uvc_ctrl_status_event_async() takes care of control changes asynchronously. If the code is executed in the following order: CPU 0 CPU 1 ===== ===== uvc_status_complete() uvc_status_stop() uvc_ctrl_status_event_work() uvc_status_start() -> FAIL Then uvc_status_start will keep failing and this error will be shown: <4>[ 5.540139] URB 0000000000000000 submitted while active drivers/usb/core/urb.c:378 usb_submit_urb+0x4c3/0x528 Let's improve the current situation, by not re-submiting the urb if we are stopping the status event. Also process the queued work (if any) during stop. CPU 0 CPU 1 ===== ===== uvc_status_complete() uvc_status_stop() uvc_status_start() uvc_ctrl_status_event_work() -> FAIL Hopefully, with the usb layer protection this should be enough to cover all the cases.

[PATCH v2] matroxfb: G200eW: Increase max memory from 1 MB to 16 MB

by Paul Menzel

Commit 62d89a7d49af ("video: fbdev: matroxfb: set maxvram of vbG200eW to the same as vbG200 to avoid black screen") accidently decreases the maximum memory size for the Matrox G200eW (102b:0532) from 8 MB to 1 MB by missing one zero. This caused the driver initialization to fail with the messages below, as the minimum required VRAM size is 2 MB: [ 9.436420] matroxfb: Matrox MGA-G200eW (PCI) detected [ 9.444502] matroxfb: cannot determine memory size [ 9.449316] matroxfb: probe of 0000:0a:03.0 failed with error -1 So, add the missing 0 to make it the intended 16 MB. Successfully tested on the Dell PowerEdge R910/0KYD3D, BIOS 2.10.0 08/29/2013, that the warning is gone. While at it, add a leading 0 to the maxdisplayable entry, so it’s aligned properly. The value could probably also be increased from 8 MB to 16 MB, as the G200 uses the same values, but I have not checked any datasheet. Note, matroxfb is obsolete and superseded by the maintained DRM driver mga200, which is used by default on most systems where both drivers are available. Therefore, on most systems it was only a cosmetic issue.

[PATCH v4] media: uvcvideo: Fix race condition with usb_kill_urb

by Ricardo Ribalda

usb_kill_urb warranties that all the handlers are finished when it returns, but does not protect against threads that might be handling asynchronously the urb. For UVC, the function uvc_ctrl_status_event_async() takes care of control changes asynchronously. If the code is executed in the following order: CPU 0 CPU 1 ===== ===== uvc_status_complete() uvc_status_stop() uvc_ctrl_status_event_work() uvc_status_start() -> FAIL Then uvc_status_start will keep failing and this error will be shown: <4>[ 5.540139] URB 0000000000000000 submitted while active drivers/usb/core/urb.c:378 usb_submit_urb+0x4c3/0x528 Let's improve the current situation, by not re-submiting the urb if we are stopping the status event. Also process the queued work (if any) during stop. CPU 0 CPU 1 ===== ===== uvc_status_complete() uvc_status_stop() uvc_status_start() uvc_ctrl_status_event_work() -> FAIL Hopefully, with the usb layer protection this should be enough to cover all the cases.

This has an undesirable consequence that e.g. if sda and sdb are assembled to a RAID1 device md0 with partitions, BLKRRPART ioctl on sda will rescan partition table and create sda1 device. This partition device under a raid device confuses some programs (such as libstorage-ng used for initial partitioning for distribution installation) leading to failures. Fix the problem refusing to rescan partitions if there is another user that has the block device exclusively open.

This commit move inode_init_owner() into ovl_create_object(), so the ovl_link() just give the old inode to ovl_create_or_link(). Then the override fsuid becomes the old inode's fsuid, neither the caller nor the overlay's mounter! So this is incorrect.

The same problem does not occur on x86-64 and he also reported that converting sb->s_inode_wblist_lock to raw_spinlock_t makes the problem disappear indicating that the RT spinlock variant is the problem. Which in turn means that RT mutexes on ARM64 and any other weakly ordered architecture are affected by this independent of RT. Will Deacon observed: "I'd be more inclined to be suspicious of the slowpath tbh, as we need to make sure that we have acquire semantics on all paths where the lock can be taken. Looking at the rtmutex code, this really isn't obvious to me -- for example, try_to_take_rt_mutex() appears to be able to return via the 'takeit' label without acquire semantics and it looks like we might be relying on the caller's subsequent _unlock_ of the wait_lock for ordering, but that will give us release semantics which aren't correct." Sebastian Andrzej Siewior prototyped a fix that does work based on that comment but it was a little bit overkill and added some fences that should not be necessary. The lock owner is updated with an IRQ-safe raw spinlock held, but the spin_unlock does not provide acquire semantics which are needed when acquiring a mutex. Adds the necessary acquire semantics for lock owner updates in the slow path acquisition and the waiter bit logic. It successfully completed 10 iterations of the dbench workload while the vanilla kernel fails on the first iteration.

by Ferry Toth

This reverts commit 8a7b31d545d3a15f0e6f5984ae16f0ca4fd76aac. This patch results in some qemu test failures, specifically xilinx-zynq-a9 machine and zynq-zc702 as well as zynq-zed devicetree files, when trying to boot from USB drive.

by syzbot

This bug is marked as fixed by commit: net: core: netlink: add helper refcount dec and lock function net: sched: add helper function to take reference to Qdisc net: sched: extend Qdisc with rcu net: sched: rename qdisc_destroy() to qdisc_put() net: sched: use Qdisc rcu API instead of relying on rtnl lock But I can't find it in the tested trees[1] for more than 90 days. Is it a correct commit? Please update it by replying: #syz fix: exact-commit-title Until then the bug is still considered open and new crashes with the same signature are ignored. Kernel: Linux 4.19 Dashboard link: https://syzkaller.appspot.com/bug?extid=5f229e48cccc804062c0 --- [1] I expect the commit to be present in: 1. linux-4.19.y branch of git://git.kernel.org/pub/scm/linux/kernel/git/stable/linux-stable.git
