FAILED: patch "[PATCH] ext4: fix potential race between s_flex_groups online" failed to apply to 4.14-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>. thanks, greg k-h ------------------ original commit in Linus's tree ------------------ >From 7c990728b99ed6fbe9c75fc202fce1172d9916da Mon Sep 17 00:00:00 2001 From: Suraj Jitindar Singh <surajjs(a)amazon.com> Date: Tue, 18 Feb 2020 19:08:51 -0800 Subject: [PATCH] ext4: fix potential race between s_flex_groups online resizing and access During an online resize an array of s_flex_groups structures gets replaced so it can get enlarged. If there is a concurrent access to the array and this memory has been reused then this can lead to an invalid memory access. The s_flex_group array has been converted into an array of pointers rather than an array of structures. This is to ensure that the information contained in the structures cannot get out of sync during a resize due to an accessor updating the value in the old structure after it has been copied but before the array pointer is updated. Since the structures them- selves are no longer copied but only the pointers to them this case is mitigated.

In particular, moving a head from one encoder to another seems to trigger this quite often. GV100+ is very picky about having a LUT in most scenarios, so this causes the display engine to hang with the following error code: disp: chid 1 stat 00005080 reason 5 [INVALID_STATE] mthd 0200 data 00000001 code 0000002d) So, fix this by always re-programming the LUT if we're clearing it in a state where the wndw is still visible, and has a XLUT handle programmed.

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>. thanks, greg k-h ------------------ original commit in Linus's tree ------------------ >From 2464cc4c345699adea52c7aef75707207cb8a2f6 Mon Sep 17 00:00:00 2001 From: Gustavo Luiz Duarte <gustavold(a)linux.ibm.com> Date: Tue, 11 Feb 2020 00:38:29 -0300 Subject: [PATCH] powerpc/tm: Fix clearing MSR[TS] in current when reclaiming on signal delivery After a treclaim, we expect to be in non-transactional state. If we don't clear the current thread's MSR[TS] before we get preempted, then tm_recheckpoint_new_task() will recheckpoint and we get rescheduled in suspended transaction state. When handling a signal caught in transactional state, handle_rt_signal64() calls get_tm_stackpointer() that treclaims the transaction using tm_reclaim_current() but without clearing the thread's MSR[TS]. This can cause the TM Bad Thing exception below if later we pagefault and get preempted trying to access the user's sigframe, using __put_user(). Afterwards, when we are rescheduled back into do_page_fault() (but now in suspended state since the thread's MSR[TS] was not cleared), upon executing 'rfid' after completion of the page fault handling, the exception is raised because a transition from suspended to non-transactional state is invalid.

In order to make treclaim and clearing the thread's MSR[TS] atomic from a preemption perspective when CONFIG_PREEMPT is set, preempt_disable/enable() is used. It's also necessary to save the previous value of the thread's MSR before get_tm_stackpointer() is called so that it can be exposed to the signal handler later in setup_tm_sigcontexts() to inform the userspace MSR at the moment of the signal delivery. Found with tm-signal-context-force-tm kernel selftest.

[PATCH tip/core/rcu 30/30] rcu: Make rcu_barrier() account for offline no-CBs CPUs

by paulmck＠kernel.org

From: "Paul E. McKenney" <paulmck(a)kernel.org> Currently, rcu_barrier() ignores offline CPUs, However, it is possible for an offline no-CBs CPU to have callbacks queued, and rcu_barrier() must wait for those callbacks. This commit therefore makes rcu_barrier() directly invoke the rcu_barrier_func() with interrupts disabled for such CPUs. This requires passing the CPU number into this function so that it can entrain the rcu_barrier() callback onto the correct CPU's callback list, given that the code must instead execute on the current CPU. While in the area, this commit fixes a bug where the first CPU's callback might have been invoked before rcu_segcblist_entrain() returned, which would also result in an early wakeup.

[PATCH] MIPS: Fix CONFIG_MIPS_CMDLINE_DTB_EXTEND handling

The CONFIG_MIPS_CMDLINE_DTB_EXTEND option is used so that the kernel arguments provided in the 'bootargs' property in devicetree are extended with the kernel arguments provided by the bootloader.

FAILED: patch "[PATCH] drm/i915: Wean off drm_pci_alloc/drm_pci_free" failed to apply to 4.19-stable tree

Furthermore since commit de09d31dd38a50fdce106c15abd68432eebbd014 Author: Kirill A. Shutemov <kirill.shutemov(a)linux.intel.com> Date: Fri Jan 15 16:51:42 2016 -0800 page-flags: define PG_reserved behavior on compound pages As far as I can see there's no users of PG_reserved on compound pages. Let's use PF_NO_COMPOUND here. drm_pci_alloc has been declared broken since it mixes GFP_COMP and SetPageReserved. Avoid this conflict by weaning ourselves off using the abstraction and using the dma functions directly.

If so, the irqflags have to be configured accordingly. The reason is: The 8250 port startup code performs IRQ tests *before* the IRQ handler for that particular port is registered. This is performed in serial8250_do_startup(). This function checks whether IRQF_SHARED is configured and only then disables the IRQ line while testing. This test is performed upon each open() of the UART device. Imagine two UARTs share the same IRQ line: On is already opened and the IRQ is active. When the second UART is opened, the IRQ line has to be disabled while performing IRQ tests. Otherwise an IRQ might handler might be invoked, but the IRQ itself cannot be handled, because the corresponding handler isn't registered, yet. That's because the 8250 code uses a chain-handler and invokes the corresponding port's IRQ handling routines himself. Unfortunately this IRQF_SHARED flag isn't configured for UARTs probed via device tree even if the IRQs are shared. This way, the actual and shared IRQ line isn't disabled while performing tests and the kernel correctly detects a spurious IRQ. So, adding this flag to the DT probe solves the issue. Note: The UPF_SHARE_IRQ flag is configured unconditionally. Therefore, the IRQF_SHARED flag can be set unconditionally as well.

If we don't clear the current thread's MSR[TS] before we get preempted, then tm_recheckpoint_new_task() will recheckpoint and we get rescheduled in suspended transaction state. When handling a signal caught in transactional state, handle_rt_signal64() calls get_tm_stackpointer() that treclaims the transaction using tm_reclaim_current() but without clearing the thread's MSR[TS]. This can cause the TM Bad Thing exception below if later we pagefault and get preempted trying to access the user's sigframe, using __put_user(). Afterwards, when we are rescheduled back into do_page_fault() (but now in suspended state since the thread's MSR[TS] was not cleared), upon executing 'rfid' after completion of the page fault handling, the exception is raised because a transition from suspended to non-transactional state is invalid.

In order to make treclaim and clearing the thread's MSR[TS] atomic from a preemption perspective when CONFIG_PREEMPT is set, preempt_disable/enable() is used. It's also necessary to save the previous value of the thread's MSR before get_tm_stackpointer() is called so that it can be exposed to the signal handler later in setup_tm_sigcontexts() to inform the userspace MSR at the moment of the signal delivery.

In order to make treclaim and clearing the thread's MSR[TS] atomic from a preemption perspective when CONFIG_PREEMPT is set, preempt_disable/enable() is used. It's also necessary to save the previous value of the thread's MSR before get_tm_stackpointer() is called so that it can be exposed to the signal handler later in setup_tm_sigcontexts() to inform the userspace MSR at the moment of the signal delivery.

usb: host: xhci: update event ring dequeue pointer on purpose

by Fabio Estevam

From: Peter Chen <peter.chen(a)nxp.com> [ Upstream commit dc0ffbea5729a3abafa577ebfce87f18b79e294b ] On some situations, the software handles TRB events slower than adding TRBs, then xhci_handle_event can't return zero long time, the xHC will consider the event ring is full, and trigger "Event Ring Full" error, but in fact, the software has already finished lots of events, just no chance to update ERDP (event ring dequeue pointer). In this commit, we force update ERDP if half of TRBS_PER_SEGMENT events have handled to avoid "Event Ring Full" error.

Memory was allocated for one PSI table under the xhci hub structure. Turns out this is not the case, some controllers have a separate "supported protocol capability" entry with a PSI table for each port. This means each usb3 roothub port can in theory support different custom speeds. To solve this, cache all supported protocol capabilities with their PSI tables in an array, and add pointers to the xhci port structure so that every port points to its capability entry in the array. When creating the SuperSpeedPlus USB Device Capability BOS descriptor for the xhci USB 3.1 roothub we for now will use only data from the first USB 3.1 capable protocol capability entry in the array.

[PATCH v3 1/2] x86/efi: Add TPM related EFI tables to unencrypted mapping checks

by Tom Lendacky

When booting with SME active, EFI tables must be mapped unencrypted since they were built by UEFI in unencrypted memory. Update the list of tables to be checked during early_memremap() processing to account for the EFI TPM tables. This fixes a bug where an EFI TPM log table has been created by UEFI, but it lives in memory that has been marked as usable rather than reserved.

Sorry, I only see this change as critical for 4.20+ kernels (where it started biting folks), but I'd defer to Felipe if he'd like to see it go any further back. thanks -john

+ mm-hotplug-fix-page-online-with-debug_pagealloc-compiled-but-not-enabled.patch added to -mm tree

by Andrew Morton

The patch titled Subject: mm, hotplug: fix page online with DEBUG_PAGEALLOC compiled but not enabled has been added to the -mm tree. Its filename is mm-hotplug-fix-page-online-with-debug_pagealloc-compiled-but-not-enabled.patch This patch should soon appear at http://ozlabs.org/~akpm/mmots/broken-out/mm-hotplug-fix-page-online-with-de… and later at http://ozlabs.org/~akpm/mmotm/broken-out/mm-hotplug-fix-page-online-with-de… Before you just go and hit "reply", please: a) Consider who else should be cc'ed b) Prefer to cc a suitable mailing list as well c) Ideally: find the original patch on the mailing list and do a reply-to-all to that, adding suitable additional cc's *** Remember to use Documentation/process/submit-checklist.rst when testing your code *** The -mm tree is included into linux-next and is updated there every 3-4 working days ------------------------------------------------------ From: Vlastimil Babka <vbabka(a)suse.cz> Subject: mm, hotplug: fix page online with DEBUG_PAGEALLOC compiled but not enabled Commit cd02cf1aceea ("mm/hotplug: fix an imbalance with DEBUG_PAGEALLOC") fixed memory hotplug with debug_pagealloc enabled, where onlining a page goes through page freeing, which removes the direct mapping. Some arches don't like when the page is not mapped in the first place, so generic_online_page() maps it first. This is somewhat wasteful, but better than special casing page freeing fast paths. The commit however missed that DEBUG_PAGEALLOC configured doesn't mean it's actually enabled. One has to test debug_pagealloc_enabled() since 031bc5743f15 ("mm/debug-pagealloc: make debug-pagealloc boottime configurable"), or alternatively debug_pagealloc_enabled_static() since 8e57f8acbbd1 ("mm, debug_pagealloc: don't rely on static keys too early"), but this is not done. As a result, a s390 kernel with DEBUG_PAGEALLOC configured but not enabled will crash: Unable to handle kernel pointer dereference in virtual kernel address space Failing address: 0000000000000000 TEID: 0000000000000483 Fault in home space mode while using kernel ASCE.

[PATCH] zfcp: fix wrong data and display format of SFP+ temperature

by Benjamin Block

When implementing support for retrieval of local diagnostic data from the FCP channel, the wrong data format was assumed for the temperature of the local SFP+ connector. The Fibre Channel Link Services (FC-LS-3) specification is not clear on the format of the stored integer, and only after consulting the SNIA specification SFF-8472 did we realize it is stored as two's complement. Thus, the used data and display format is wrong, and highly misleading for users when the temperature should drop below 0°C (however unlikely that may be). To fix this, change the data format in `struct fsf_qtcb_bottom_port` from unsigned to signed, and change the printf format string used to generate `zfcp_sysfs_adapter_diag_sfp_temperature_show()` from `%hu` to `%hd`. Fixes: a10a61e807b0 ("scsi: zfcp: support retrieval of SFP Data via Exchange Port Data") Fixes: 6028f7c4cd87 ("scsi: zfcp: introduce sysfs interface for diagnostics of local SFP transceiver") Cc: <stable(a)vger.kernel.org> # 5.5+ Reviewed-by: Jens Remus <jremus(a)linux.ibm.com> Reviewed-by: Fedor Loshakov <loshakov(a)linux.ibm.com> Reviewed-by: Steffen Maier <maier(a)linux.ibm.com> Signed-off-by: Benjamin Block <bblock(a)linux.ibm.com> --- Hello James, Martin, please consider this patch to be included in scsi-fixes, I also tagged it for stable.

[for-linus][PATCH 06/15] tracing: Disable trace_printk() on post poned tests

by Steven Rostedt

From: "Steven Rostedt (VMware)" <rostedt(a)goodmis.org> The tracing seftests checks various aspects of the tracing infrastructure, and one is filtering. If trace_printk() is active during a self test, it can cause the filtering to fail, which will disable that part of the trace. To keep the selftests from failing because of trace_printk() calls, trace_printk() checks the variable tracing_selftest_running, and if set, it does not write to the tracing buffer. As some tracers were registered earlier in boot, the selftest they triggered would fail because not all the infrastructure was set up for the full selftest. Thus, some of the tests were post poned to when their infrastructure was ready (namely file system code). The postpone code did not set the tracing_seftest_running variable, and could fail if a trace_printk() was added and executed during their run.

[git:media_tree/master] media: hantro: Read be32 words starting at every fourth byte

by Mauro Carvalho Chehab

[PATCH] mm, hotplug: fix page online with DEBUG_PAGEALLOC compiled but not enabled

by Vlastimil Babka

Commit cd02cf1aceea ("mm/hotplug: fix an imbalance with DEBUG_PAGEALLOC") fixed memory hotplug with debug_pagealloc enabled, where onlining a page goes through page freeing, which removes the direct mapping. Some arches don't like when the page is not mapped in the first place, so generic_online_page() maps it first. This is somewhat wasteful, but better than special casing page freeing fast paths. The commit however missed that DEBUG_PAGEALLOC configured doesn't mean it's actually enabled. One has to test debug_pagealloc_enabled() since 031bc5743f15 ("mm/debug-pagealloc: make debug-pagealloc boottime configurable"), or alternatively debug_pagealloc_enabled_static() since 8e57f8acbbd1 ("mm, debug_pagealloc: don't rely on static keys too early"), but this is not done. As a result, a s390 kernel with DEBUG_PAGEALLOC configured but not enabled will crash: Unable to handle kernel pointer dereference in virtual kernel address space Failing address: 0000000000000000 TEID: 0000000000000483 Fault in home space mode while using kernel ASCE.

[PATCH] jbd2: fix ocfs2 corrupt when clearing block group bits

by wangyan

I found a NULL pointer dereference in ocfs2_block_group_clear_bits(). The running environment: kernel version: 4.19 A cluster with two nodes, 5 luns mounted on two nodes, and do some file operations like dd/fallocate/truncate/rm on every lun with storage network disconnection. The fallocate operation on dm-23-45 caused an null pointer dereference. The information of NULL pointer dereference as follows: [577992.878282] JBD2: Error -5 detected when updating journal superblock for dm-23-45. [577992.878290] Aborting journal on device dm-23-45. ...

The bh2jh(group_bh) can be removed after ocfs2_journal_access_gd() and before call "bh2jh(group_bh)->b_committed_data". So, we should move is_handle_aborted() check from do_get_write_access() into jbd2_journal_get_undo_access() and jbd2_journal_get_write_access() before the call to jbd2_write_access_granted().

Isn't that what I did when I replied to the AUTOSEL mail a week ago? https://lore.kernel.org/stable/a920b57f-ad9e-5c25-3981-0462febd952a@rasmusv… The TL;DR is the last part of the middle paragraph "... I think they should not be added to any -stable kernel." Rasmus

For 1G hugepages, huge_pte_offset() wants to return NULL or pudp, but it may return a wrong 'pmdp' if there is a race. Please look at the following code snippet: ... pud = pud_offset(p4d, addr); if (sz != PUD_SIZE && pud_none(*pud)) return NULL; /* hugepage or swap? */ if (pud_huge(*pud) || !pud_present(*pud)) return (pte_t *)pud; pmd = pmd_offset(pud, addr); if (sz != PMD_SIZE && pmd_none(*pmd)) return NULL; /* hugepage or swap? */ if (pmd_huge(*pmd) || !pmd_present(*pmd)) return (pte_t *)pmd; ... The following sequence would trigger this bug: 1. CPU0: sz = PUD_SIZE and *pud = 0 , continue 1. CPU0: "pud_huge(*pud)" is false 2. CPU1: calling hugetlb_no_page and set *pud to xxxx8e7(PRESENT) 3. CPU0: "!pud_present(*pud)" is false, continue 4. CPU0: pmd = pmd_offset(pud, addr) and maybe return a wrong pmdp However, we want CPU0 to return NULL or pudp. We can avoid this race by reading the pud only once. What's more, we also use READ_ONCE to access the entries for safety (i.e. avoid the compilier mischief) Link: http://lkml.kernel.org/r/1582342427-230392-1-git-send-email-longpeng2@huawe… Signed-off-by: Longpeng <longpeng2(a)huawei.com> Cc: Matthew Wilcox <willy(a)infradead.org> Cc: Sean Christopherson <sean.j.christopherson(a)intel.com> Cc: Mike Kravetz <mike.kravetz(a)oracle.com> Cc: <stable(a)vger.kernel.org> Signed-off-by: Andrew Morton <akpm(a)linux-foundation.org> --- mm/hugetlb.c | 18 ++++++++++-------- 1 file changed, 10 insertions(+), 8 deletions(-) --- a/mm/hugetlb.c~mm-hugetlb-fix-a-addressing-exception-caused-by-huge_pte_offset +++ a/mm/hugetlb.c @@ -4910,28 +4910,30 @@ pte_t *huge_pte_offset(struct mm_struct { pgd_t *pgd; p4d_t *p4d; - pud_t *pud; - pmd_t *pmd; + pud_t *pud, pud_entry; + pmd_t *pmd, pmd_entry; pgd = pgd_offset(mm, addr); - if (!pgd_present(*pgd)) + if (!pgd_present(READ_ONCE(*pgd))) return NULL; p4d = p4d_offset(pgd, addr); - if (!p4d_present(*p4d)) + if (!p4d_present(READ_ONCE(*p4d))) return NULL; pud = pud_offset(p4d, addr); - if (sz != PUD_SIZE && pud_none(*pud)) + pud_entry = READ_ONCE(*pud); + if (sz != PUD_SIZE && pud_none(pud_entry)) return NULL; /* hugepage or swap? */ - if (pud_huge(*pud) || !pud_present(*pud)) + if (pud_huge(pud_entry) || !pud_present(pud_entry)) return (pte_t *)pud; pmd = pmd_offset(pud, addr); - if (sz != PMD_SIZE && pmd_none(*pmd)) + pmd_entry = READ_ONCE(*pmd); + if (sz != PMD_SIZE && pmd_none(pmd_entry)) return NULL; /* hugepage or swap? */ - if (pmd_huge(*pmd) || !pmd_present(*pmd)) + if (pmd_huge(pmd_entry) || !pmd_present(pmd_entry)) return (pte_t *)pmd; return NULL; _ Patches currently in -mm which might be from longpeng2(a)huawei.com are mm-hugetlb-fix-a-addressing-exception-caused-by-huge_pte_offset.patch

[PATCH] Revert "PM / devfreq: Modify the device name as devfreq(X) for sysfs"

by Orson Zhai

This reverts commit 4585fbcb5331fc910b7e553ad3efd0dd7b320d14. The name changing as devfreq(X) breaks some user space applications, such as Android HAL from Unisoc and Hikey [1]. The device name will be changed unexpectly after every boot depending on module init sequence. It will make trouble to setup some system configuration like selinux for Android. So we'd like to revert it back to old naming rule before any better way being found.

[PATCH] platform/x86: asus-wmi: Support laptops where the first battery is named BATT

by Kristian Klausen

The WMI method to set the charge threshold does not provide a way to specific a battery, so we assume it is the first/primary battery (by checking if the name is BAT0). On some newer ASUS laptops (Zenbook UM431DA) though, the primary/first battery isn't named BAT0 but BATT, so we need to support that case. Signed-off-by: Kristian Klausen <kristian(a)klausen.dk> Cc: stable(a)vger.kernel.org --- I'm not sure if this is candidate for -stable, it fix a real bug (charge threshold doesn't work on newer ASUS laptops) which has been reported by a user[1], but is that enough? I had a quick look at[2], can this be considered a "something critical"? It "bothers people"[1]. My point: I'm not sure.. I'm unsure if there is a bettery way to fix this. Maybe a counter would be better (+1 for every new battery)? It would probably need to be atomic to prevent race condition (I'm not sure how this code is run), but this "fix" is way simpler. Please do not accept this patch just yet, I'm waiting for the tester to either confirm or deny credit[3].

by akpm＠linux-foundation.org

The patch titled Subject: mm/vmscan.c: don't round up scan size for online memory cgroup has been removed from the -mm tree. Its filename was mm-vmscan-dont-round-up-scan-size-for-online-memory-cgroup.patch This patch was dropped because it was merged into mainline or a subsystem tree ------------------------------------------------------ From: Gavin Shan <gshan(a)redhat.com> Subject: mm/vmscan.c: don't round up scan size for online memory cgroup commit 68600f623d69 ("mm: don't miss the last page because of round-off error") makes the scan size round up to @denominator regardless of the memory cgroup's state, online or offline. This affects the overall reclaiming behavior: The corresponding LRU list is eligible for reclaiming only when its size logically right shifted by @sc->priority is bigger than zero in the former formula. For example, the inactive anonymous LRU list should have at least 0x4000 pages to be eligible for reclaiming when we have 60/12 for swappiness/priority and without taking scan/rotation ratio into account. After the roundup is applied, the inactive anonymous LRU list becomes eligible for reclaiming when its size is bigger than or equal to 0x1000 in the same condition. (0x4000 >> 12) * 60 / (60 + 140 + 1) = 1 ((0x1000 >> 12) * 60) + 200) / (60 + 140 + 1) = 1 aarch64 has 512MB huge page size when the base page size is 64KB. The memory cgroup that has a huge page is always eligible for reclaiming in that case. The reclaiming is likely to stop after the huge page is reclaimed, meaing the further iteration on @sc->priority and the silbing and child memory cgroups will be skipped. The overall behaviour has been changed. This fixes the issue by applying the roundup to offlined memory cgroups only, to give more preference to reclaim memory from offlined memory cgroup. It sounds reasonable as those memory is unlikedly to be used by anyone. The issue was found by starting up 8 VMs on a Ampere Mustang machine, which has 8 CPUs and 16 GB memory. Each VM is given with 2 vCPUs and 2GB memory. It took 264 seconds for all VMs to be completely up and 784MB swap is consumed after that. With this patch applied, it took 236 seconds and 60MB swap to do same thing. So there is 10% performance improvement for my case. Note that KSM is disable while THP is enabled in the testing. total used free shared buff/cache available Mem: 16196 10065 2049 16 4081 3749 Swap: 8175 784 7391 total used free shared buff/cache available Mem: 16196 11324 3656 24 1215 2936 Swap: 8175 60 8115 Link: http://lkml.kernel.org/r/20200211024514.8730-1-gshan@redhat.com Fixes: 68600f623d69 ("mm: don't miss the last page because of round-off error") Signed-off-by: Gavin Shan <gshan(a)redhat.com> Acked-by: Roman Gushchin <guro(a)fb.com> Cc: <stable(a)vger.kernel.org> [4.20+] Signed-off-by: Andrew Morton <akpm(a)linux-foundation.org> --- mm/vmscan.c | 9 ++++++--- 1 file changed, 6 insertions(+), 3 deletions(-) --- a/mm/vmscan.c~mm-vmscan-dont-round-up-scan-size-for-online-memory-cgroup +++ a/mm/vmscan.c @@ -2415,10 +2415,13 @@ out: /* * Scan types proportional to swappiness and * their relative recent reclaim efficiency. - * Make sure we don't miss the last page - * because of a round-off error. + * Make sure we don't miss the last page on + * the offlined memory cgroups because of a + * round-off error. */ - scan = DIV64_U64_ROUND_UP(scan * fraction[file], + scan = mem_cgroup_online(memcg) ? + div64_u64(scan * fraction[file], denominator) : + DIV64_U64_ROUND_UP(scan * fraction[file], denominator); break; case SCAN_FILE: _ Patches currently in -mm which might be from gshan(a)redhat.com are

[merged] revert-ipcsem-remove-uneeded-sem_undo_list-lock-usage-in-exit_sem.patch removed from -mm tree

by akpm＠linux-foundation.org

The patch titled Subject: Revert "ipc,sem: remove uneeded sem_undo_list lock usage in exit_sem()" has been removed from the -mm tree. Its filename was revert-ipcsem-remove-uneeded-sem_undo_list-lock-usage-in-exit_sem.patch This patch was dropped because it was merged into mainline or a subsystem tree ------------------------------------------------------ From: Ioanna Alifieraki <ioanna-maria.alifieraki(a)canonical.com> Subject: Revert "ipc,sem: remove uneeded sem_undo_list lock usage in exit_sem()" This reverts commit a97955844807e327df11aa33869009d14d6b7de0. Commit a97955844807 ("ipc,sem: remove uneeded sem_undo_list lock usage in exit_sem()") removes a lock that is needed. This leads to a process looping infinitely in exit_sem() and can also lead to a crash. There is a reproducer available in [1] and with the commit reverted the issue does not reproduce anymore. Using the reproducer found in [1] is fairly easy to reach a point where one of the child processes is looping infinitely in exit_sem between for(;;) and if (semid == -1) block, while it's trying to free its last sem_undo structure which has already been freed by freeary(). Each sem_undo struct is on two lists: one per semaphore set (list_id) and one per process (list_proc). The list_id list tracks undos by semaphore set, and the list_proc by process. Undo structures are removed either by freeary() or by exit_sem(). The freeary function is invoked when the user invokes a syscall to remove a semaphore set. During this operation freeary() traverses the list_id associated with the semaphore set and removes the undo structures from both the list_id and list_proc lists. For this case, exit_sem() is called at process exit. Each process contains a struct sem_undo_list (referred to as "ulp") which contains the head for the list_proc list. When the process exits, exit_sem() traverses this list to remove each sem_undo struct. As in freeary(), whenever a sem_undo struct is removed from list_proc, it is also removed from the list_id list. Removing elements from list_id is safe for both exit_sem() and freeary() due to sem_lock(). Removing elements from list_proc is not safe; freeary() locks &un->ulp->lock when it performs list_del_rcu(&un->list_proc) but exit_sem() does not (locking was removed by commit a97955844807 ("ipc,sem: remove uneeded sem_undo_list lock usage in exit_sem()"). This can result in the following situation while executing the reproducer [1] : Consider a child process in exit_sem() and the parent in freeary() (because of semctl(sid[i], NSEM, IPC_RMID)). The list_proc for the child contains the last two undo structs A and B (the rest have been removed either by exit_sem() or freeary()). The semid for A is 1 and semid for B is 2. exit_sem() removes A and at the same time freeary() removes B. Since A and B have different semid sem_lock() will acquire different locks for each process and both can proceed. The bug is that they remove A and B from the same list_proc at the same time because only freeary() acquires the ulp lock. When exit_sem() removes A it makes ulp->list_proc.next to point at B and at the same time freeary() removes B setting B->semid=-1. At the next iteration of for(;;) loop exit_sem() will try to remove B. The only way to break from for(;;) is for (&un->list_proc == &ulp->list_proc) to be true which is not. Then exit_sem() will check if B->semid=-1 which is and will continue looping in for(;;) until the memory for B is reallocated and the value at B->semid is changed. At that point, exit_sem() will crash attempting to unlink B from the lists (this can be easily triggered by running the reproducer [1] a second time). To prove this scenario instrumentation was added to keep information about each sem_undo (un) struct that is removed per process and per semaphore set (sma). CPU0 CPU1 [caller holds sem_lock(sma for A)] ... freeary() exit_sem() ... ... ... sem_lock(sma for B) spin_lock(A->ulp->lock) ... list_del_rcu(un_A->list_proc) list_del_rcu(un_B->list_proc) Undo structures A and B have different semid and sem_lock() operations proceed. However they belong to the same list_proc list and they are removed at the same time. This results into ulp->list_proc.next pointing to the address of B which is already removed. After reverting commit a97955844807 ("ipc,sem: remove uneeded sem_undo_list lock usage in exit_sem()") the issue was no longer reproducible.

[PATCH] vhost: Check docket sk_family instead of call getname

by Eugenio Pérez

Doing so, we save one call to get data we already have in the struct. Also, since there is no guarantee that getname use sockaddr_ll parameter beyond its size, we add a little bit of security here. It should do not do beyond MAX_ADDR_LEN, but syzbot found that ax25_getname writes more (72 bytes, the size of full_sockaddr_ax25, versus 20 + 32 bytes of sockaddr_ll + MAX_ADDR_LEN in syzbot repro).

Applied "spi: spidev: Fix CS polarity if GPIO descriptors are used" to the spi tree

by Mark Brown

The patch spi: spidev: Fix CS polarity if GPIO descriptors are used has been applied to the spi tree at https://git.kernel.org/pub/scm/linux/kernel/git/broonie/spi.git for-5.6 All being well this means that it will be integrated into the linux-next tree (usually sometime in the next 24 hours) and sent to Linus during the next merge window (or sooner if it is a bug fix), however if problems are discovered then the patch may be dropped or reverted. You may get further e-mails resulting from automated or manual testing and review of the tree, please engage with people reporting problems and send followup patches addressing any issues that are reported if needed. If any updates are required or you are submitting further changes they should be sent as incremental updates against current git, existing patches will not be replaced. Please add any relevant lists and maintainers to the CCs when replying to this mail. Thanks, Mark >From 138c9c32f090894614899eca15e0bb7279f59865 Mon Sep 17 00:00:00 2001 From: Lukas Wunner <lukas(a)wunner.de> Date: Tue, 18 Feb 2020 13:08:00 +0100 Subject: [PATCH] spi: spidev: Fix CS polarity if GPIO descriptors are used Commit f3186dd87669 ("spi: Optionally use GPIO descriptors for CS GPIOs") amended of_spi_parse_dt() to always set SPI_CS_HIGH for SPI slaves whose Chip Select is defined by a "cs-gpios" devicetree property. This change broke userspace applications which issue an SPI_IOC_WR_MODE ioctl() to an spidev: Chip Select polarity will be incorrect unless the application is changed to set SPI_CS_HIGH. And once changed, it will be incompatible with kernels not containing the commit. Fix by setting SPI_CS_HIGH in spidev_ioctl() (under the same conditions as in of_spi_parse_dt()).

The new dstate IRQD_MSI_NOMASK_QUIRK came out surprisingly while it should only be the x86 stuff for the time being... The new MSI quirk flag uses the same bit as IRQ_DOMAIN_NAME_ALLOCATED which is oddly defined as bit 6 for no good reason. Switch it to the non used bit 1.

[patch 14/15] lib/stackdepot.c: fix global out-of-bounds in stack_slabs

by akpm＠linux-foundation.org

From: Alexander Potapenko <glider(a)google.com> Subject: lib/stackdepot.c: fix global out-of-bounds in stack_slabs Walter Wu has reported a potential case in which init_stack_slab() is called after stack_slabs[STACK_ALLOC_MAX_SLABS - 1] has already been initialized. In that case init_stack_slab() will overwrite stack_slabs[STACK_ALLOC_MAX_SLABS], which may result in a memory corruption.

From: Gavin Shan <gshan(a)redhat.com> Subject: mm/vmscan.c: don't round up scan size for online memory cgroup commit 68600f623d69 ("mm: don't miss the last page because of round-off error") makes the scan size round up to @denominator regardless of the memory cgroup's state, online or offline. This affects the overall reclaiming behavior: The corresponding LRU list is eligible for reclaiming only when its size logically right shifted by @sc->priority is bigger than zero in the former formula. For example, the inactive anonymous LRU list should have at least 0x4000 pages to be eligible for reclaiming when we have 60/12 for swappiness/priority and without taking scan/rotation ratio into account. After the roundup is applied, the inactive anonymous LRU list becomes eligible for reclaiming when its size is bigger than or equal to 0x1000 in the same condition. (0x4000 >> 12) * 60 / (60 + 140 + 1) = 1 ((0x1000 >> 12) * 60) + 200) / (60 + 140 + 1) = 1 aarch64 has 512MB huge page size when the base page size is 64KB. The memory cgroup that has a huge page is always eligible for reclaiming in that case. The reclaiming is likely to stop after the huge page is reclaimed, meaing the further iteration on @sc->priority and the silbing and child memory cgroups will be skipped. The overall behaviour has been changed. This fixes the issue by applying the roundup to offlined memory cgroups only, to give more preference to reclaim memory from offlined memory cgroup. It sounds reasonable as those memory is unlikedly to be used by anyone. The issue was found by starting up 8 VMs on a Ampere Mustang machine, which has 8 CPUs and 16 GB memory. Each VM is given with 2 vCPUs and 2GB memory. It took 264 seconds for all VMs to be completely up and 784MB swap is consumed after that. With this patch applied, it took 236 seconds and 60MB swap to do same thing. So there is 10% performance improvement for my case.

[patch 04/15] Revert "ipc,sem: remove uneeded sem_undo_list lock usage in exit_sem()"

by akpm＠linux-foundation.org

From: Ioanna Alifieraki <ioanna-maria.alifieraki(a)canonical.com> Subject: Revert "ipc,sem: remove uneeded sem_undo_list lock usage in exit_sem()" This reverts commit a97955844807e327df11aa33869009d14d6b7de0. Commit a97955844807 ("ipc,sem: remove uneeded sem_undo_list lock usage in exit_sem()") removes a lock that is needed. This leads to a process looping infinitely in exit_sem() and can also lead to a crash. There is a reproducer available in [1] and with the commit reverted the issue does not reproduce anymore. Using the reproducer found in [1] is fairly easy to reach a point where one of the child processes is looping infinitely in exit_sem between for(;;) and if (semid == -1) block, while it's trying to free its last sem_undo structure which has already been freed by freeary(). Each sem_undo struct is on two lists: one per semaphore set (list_id) and one per process (list_proc). The list_id list tracks undos by semaphore set, and the list_proc by process. Undo structures are removed either by freeary() or by exit_sem(). The freeary function is invoked when the user invokes a syscall to remove a semaphore set. During this operation freeary() traverses the list_id associated with the semaphore set and removes the undo structures from both the list_id and list_proc lists. For this case, exit_sem() is called at process exit. Each process contains a struct sem_undo_list (referred to as "ulp") which contains the head for the list_proc list. When the process exits, exit_sem() traverses this list to remove each sem_undo struct. As in freeary(), whenever a sem_undo struct is removed from list_proc, it is also removed from the list_id list. Removing elements from list_id is safe for both exit_sem() and freeary() due to sem_lock(). Removing elements from list_proc is not safe; freeary() locks &un->ulp->lock when it performs list_del_rcu(&un->list_proc) but exit_sem() does not (locking was removed by commit a97955844807 ("ipc,sem: remove uneeded sem_undo_list lock usage in exit_sem()"). This can result in the following situation while executing the reproducer [1] : Consider a child process in exit_sem() and the parent in freeary() (because of semctl(sid[i], NSEM, IPC_RMID)). The list_proc for the child contains the last two undo structs A and B (the rest have been removed either by exit_sem() or freeary()). The semid for A is 1 and semid for B is 2. exit_sem() removes A and at the same time freeary() removes B. Since A and B have different semid sem_lock() will acquire different locks for each process and both can proceed. The bug is that they remove A and B from the same list_proc at the same time because only freeary() acquires the ulp lock. When exit_sem() removes A it makes ulp->list_proc.next to point at B and at the same time freeary() removes B setting B->semid=-1. At the next iteration of for(;;) loop exit_sem() will try to remove B. The only way to break from for(;;) is for (&un->list_proc == &ulp->list_proc) to be true which is not. Then exit_sem() will check if B->semid=-1 which is and will continue looping in for(;;) until the memory for B is reallocated and the value at B->semid is changed. At that point, exit_sem() will crash attempting to unlink B from the lists (this can be easily triggered by running the reproducer [1] a second time). To prove this scenario instrumentation was added to keep information about each sem_undo (un) struct that is removed per process and per semaphore set (sma). CPU0 CPU1 [caller holds sem_lock(sma for A)] ... freeary() exit_sem() ... ... ... sem_lock(sma for B) spin_lock(A->ulp->lock) ... list_del_rcu(un_A->list_proc) list_del_rcu(un_B->list_proc) Undo structures A and B have different semid and sem_lock() operations proceed. However they belong to the same list_proc list and they are removed at the same time. This results into ulp->list_proc.next pointing to the address of B which is already removed. After reverting commit a97955844807 ("ipc,sem: remove uneeded sem_undo_list lock usage in exit_sem()") the issue was no longer reproducible.

But the PMD is read before that with an ordinary memory reading. If the THP (transparent huge page) is written between the PMD reading and pmdp_invalidate(), the PMD dirty bit may be lost, and cause data corruption. The race window is quite small, but still possible in theory, so need to be fixed. The race is fixed via using the return value of pmdp_invalidate() to get the original content of PMD, which is a read/modify/write atomic operation. So no THP writing can occur in between. The race has been introduced when the THP migration support is added in the commit 616b8371539a ("mm: thp: enable thp migration in generic path"). But this fix depends on the commit d52605d7cb30 ("mm: do not lose dirty and accessed bits in pmdp_invalidate()"). So it's easy to be backported after v4.16. But the race window is really small, so it may be fine not to backport the fix at all.

[PATCH V2] tpm: Don't make log failures fatal

by Matthew Garrett

If a TPM is in disabled state, it's reasonable for it to have an empty log. Bailing out of probe in this case means that the PPI interface isn't available, so there's no way to then enable the TPM from the OS.

[PATCH 0/6] Memory corruption may occur due to incorrent tlb flush

by Santosh Sivaraj

The TLB flush optimisation (a46cc7a90f: powerpc/mm/radix: Improve TLB/PWC flushes) may result in random memory corruption. Any concurrent page-table walk could end up with a Use-after-Free. Even on UP this might give issues, since mmu_gather is preemptible these days. An interrupt or preempted task accessing user pages might stumble into the free page if the hardware caches page directories. The series is a backport of the fix sent by Peter [1]. The first three patches are dependencies for the last patch (avoid potential double flush). If the performance impact due to double flush is considered trivial then the first three patches and last patch may be dropped. This is only for v4.19 stable.

[PATCH] serdev: Fix detection of UART devices on Apple machines.

by Ronald Tschalär

On Apple devices the _CRS method returns an empty resource template, and the resource settings are instead provided by the _DSM method. But commit 33364d63c75d6182fa369cea80315cf1bb0ee38e (serdev: Add ACPI devices by ResourceSource field) changed the search for serdev devices to require valid, non-empty resource template, thereby breaking Apple devices and causing bluetooth devices to not be found. This expands the check so that if we don't find a valid template, and we're on an Apple machine, then just check for the device being an immediate child of the controller and having a "baud" property.

[PATCH v2] usb: dwc3: gadget: Update chain bit correctly when using sg list

by John Stultz

From: Pratham Pratap <prathampratap(a)codeaurora.org> If scatter-gather operation is allowed, a large USB request is split into multiple TRBs. For preparing TRBs for sg list, driver iterates over the list and creates TRB for each sg and mark the chain bit to false for the last sg. The current IOMMU driver is clubbing the list of sgs which shares a page boundary into one and giving it to USB driver. With this the number of sgs mapped it not equal to the the number of sgs passed. Because of this USB driver is not marking the chain bit to false since it couldn't iterate to the last sg. This patch addresses this issue by marking the chain bit to false if it is the last mapped sg. At a practical level, this patch resolves USB transfer stalls seen with adb on dwc3 based db845c, pixel3 and other qcom hardware after functionfs gadget added scatter-gather support around v4.20. Credit also to Anurag Kumar Vulisha <anurag.kumar.vulisha(a)xilinx.com> who implemented a very similar fix to this issue.

[PATCH 2/3] ext4: fix potential race between s_group_info online resizing and access

by Suraj Jitindar Singh

During an online resize an array of pointers to s_group_info gets replaced so it can get enlarged. If there is a concurrent access to the array in ext4_get_group_info() and this memory has been reused then this can lead to an invalid memory access.

+ epoll-fix-possible-lost-wakeup-on-epoll_ctl-path.patch added to -mm tree

by akpm＠linux-foundation.org

The patch titled Subject: epoll: fix possible lost wakeup on epoll_ctl() path has been added to the -mm tree. Its filename is epoll-fix-possible-lost-wakeup-on-epoll_ctl-path.patch This patch should soon appear at http://ozlabs.org/~akpm/mmots/broken-out/epoll-fix-possible-lost-wakeup-on-… and later at http://ozlabs.org/~akpm/mmotm/broken-out/epoll-fix-possible-lost-wakeup-on-… Before you just go and hit "reply", please: a) Consider who else should be cc'ed b) Prefer to cc a suitable mailing list as well c) Ideally: find the original patch on the mailing list and do a reply-to-all to that, adding suitable additional cc's *** Remember to use Documentation/process/submit-checklist.rst when testing your code *** The -mm tree is included into linux-next and is updated there every 3-4 working days ------------------------------------------------------ From: Roman Penyaev <rpenyaev(a)suse.de> Subject: epoll: fix possible lost wakeup on epoll_ctl() path This fixes possible lost wakeup introduced by commit a218cc491420. Originally modifications to ep->wq were serialized by ep->wq.lock, but in the a218cc491420 new rw lock was introduced in order to relax fd event path, i.e. callers of ep_poll_callback() function. After the change ep_modify and ep_insert (both are called on epoll_ctl() path) were switched to ep->lock, but ep_poll (epoll_wait) was using ep->wq.lock on wqueue list modification. The bug doesn't lead to any wqueue list corruptions, because wake up path and list modifications were serialized by ep->wq.lock internally, but actual waitqueue_active() check prior wake_up() call can be reordered with modifications of ep ready list, thus wake up can be lost. And yes, can be healed by explicit smp_mb(): list_add_tail(&epi->rdlink, &ep->rdllist); smp_mb(); if (waitqueue_active(&ep->wq)) wake_up(&ep->wp); But let's make it simple, thus current patch replaces ep->wq.lock with the ep->lock for wqueue modifications, thus wake up path always observes activeness of the wqueue correcty.

[PATCH 1/3] perf/amd/uncore: Replace manual sampling check with CAP_NO_INTERRUPT flag

The workload is : read/write/modifying ranges of memory and checking the contents.

A partial : report of the bad PMD looked like : : [ 5195.338482] ../mm/pgtable-generic.c:33: bad pmd ffff8888157ba008(000002e0396009e2) : [ 5195.341184] ------------[ cut here ]------------ : [ 5195.356880] kernel BUG at ../mm/pgtable-generic.c:35! : .... : [ 5195.410033] Call Trace: : [ 5195.410471] [<ffffffff811bc75d>] change_protection_range+0x7dd/0x930 : [ 5195.410716] [<ffffffff811d4be8>] change_prot_numa+0x18/0x30 : [ 5195.410918] [<ffffffff810adefe>] task_numa_work+0x1fe/0x310 : [ 5195.411200] [<ffffffff81098322>] task_work_run+0x72/0x90 : [ 5195.411246] [<ffffffff81077139>] exit_to_usermode_loop+0x91/0xc2 : [ 5195.411494] [<ffffffff81003a51>] prepare_exit_to_usermode+0x31/0x40 : [ 5195.411739] [<ffffffff815e56af>] retint_user+0x8/0x10 : : Decoding revealed that the PMD was a valid prot_numa PMD and the bad PMD : was a false detection. The bug does not trigger if automatic NUMA : balancing or transparent huge pages is disabled. : : The bug is due a race in change_pmd_range between a pmd_trans_huge and : pmd_nond_or_clear_bad check without any locks held. During the : pmd_trans_huge check, a parallel protection update under lock can have : cleared the PMD and filled it with a prot_numa entry between the transhuge : check and the pmd_none_or_clear_bad check. : : While this could be fixed with heavy locking, it's only necessary to make : a copy of the PMD on the stack during change_pmd_range and avoid races. A : new helper is created for this as the check if quite subtle and the : existing similar helpful is not suitable. This passed 154 hours of : testing (usually triggers between 20 minutes and 24 hours) without : detecting bad PMDs or corruption. A basic test of an autonuma-intensive : workload showed no significant change in behaviour. Although Mel withdrew the patch on the face of LKML comment https://lkml.org/lkml/2017/4/10/922 the race window aforementioned is still open, and we have reports of Linpack test reporting bad residuals after the bad PMD warning is observed.

[PATCH v3] x86/cpu/amd: Enable the fixed Instructions Retired counter IRPERF

by Kim Phillips

Commit aaf248848db50 ("perf/x86/msr: Add AMD IRPERF (Instructions Retired) performance counter") added support for access to the free-running counter via 'perf -e msr/irperf/', but when exercised, we always get a 0 count: BEFORE: $ sudo perf stat -e instructions,msr/irperf/ true Performance counter stats for 'true': 624,833 instructions 0 msr/irperf/ Simply set its enable bit - HWCR bit 30 - to make it start counting. Enablement is restricted to all machines advertising IRPERF capability, except those susceptible to an erratum that makes the IRPERF return bad values. That erratum occurs in Family 17h models 00-1fh [1], but not in F17h models 20h and above [2]. AFTER (on a family 17h model 31h machine): $ sudo perf stat -e instructions,msr/irperf/ true Performance counter stats for 'true': 621,690 instructions 622,490 msr/irperf/ [1] Revision Guide for AMD Family 17h Models 00h-0Fh Processors [2] Revision Guide for AMD Family 17h Models 30h-3Fh Processors The revision guides are available from the bugzilla Link below.

[PATCH] MIPS: ingenic: DTS: Fix watchdog nodes

by Paul Cercueil

The devicetree ABI was broken on purpose by commit 6d532143c915 ("watchdog: jz4740: Use regmap provided by TCU driver"), and commit 1d9c30745455 ("watchdog: jz4740: Use WDT clock provided by TCU driver"). The commit message of the latter explains why the ABI was broken. However, the current devicetree files were not updated to the new ABI described in Documentation/devicetree/bindings/timer/ingenic,tcu.txt, so the watchdog driver would not probe. Fix this problem by updating the watchdog nodes to comply with the new ABI.

[PATCH] drm/sun4i: dsi: Avoid hotplug race with DRM driver bind

by Samuel Holland

We need to make sure that the DRM driver is fully registered before allowing the panel to be attached. Otherwise, we may trigger a hotplug event before sun4i_framebuffer_init() sets up drm->mode_config.funcs, causing a NULL pointer dereference.

[PATCH v3 1/3] powerpc/tm: Fix clearing MSR[TS] in current when reclaiming on signal delivery

by Gustavo Luiz Duarte

After a treclaim, we expect to be in non-transactional state. If we don't clear the current thread's MSR[TS] before we get preempted, then tm_recheckpoint_new_task() will recheckpoint and we get rescheduled in suspended transaction state. When handling a signal caught in transactional state, handle_rt_signal64() calls get_tm_stackpointer() that treclaims the transaction using tm_reclaim_current() but without clearing the thread's MSR[TS]. This can cause the TM Bad Thing exception below if later we pagefault and get preempted trying to access the user's sigframe, using __put_user(). Afterwards, when we are rescheduled back into do_page_fault() (but now in suspended state since the thread's MSR[TS] was not cleared), upon executing 'rfid' after completion of the page fault handling, the exception is raised because a transition from suspended to non-transactional state is invalid.

In order to make treclaim and clearing the thread's MSR[TS] atomic from a preemption perspective when CONFIG_PREEMPT is set, preempt_disable/enable() is used. It's also necessary to save the previous value of the thread's MSR before get_tm_stackpointer() is called so that it can be exposed to the signal handler later in setup_tm_sigcontexts() to inform the userspace MSR at the moment of the signal delivery. Found with tm-signal-context-force-tm kernel selftest. v3: Subject and comment improvements. v2: Fix build failure when tm is disabled.

[PATCH] usb: dwc3: gadget: Update chain bit correctly when using sg list

by John Stultz

From: Pratham Pratap <prathampratap(a)codeaurora.org> If scatter-gather operation is allowed, a large USB request is split into multiple TRBs. For preparing TRBs for sg list, driver iterates over the list and creates TRB for each sg and mark the chain bit to false for the last sg. The current IOMMU driver is clubbing the list of sgs which shares a page boundary into one and giving it to USB driver. With this the number of sgs mapped it not equal to the the number of sgs passed. Because of this USB driver is not marking the chain bit to false since it couldn't iterate to the last sg. This patch addresses this issue by marking the chain bit to false if it is the last mapped sg. At a practical level, this patch resolves USB transfer stalls seen with adb on dwc3 based db845c, pixel3 and other qcom hardware after functionfs gadget added scatter-gather support around v4.20. Credit also to Anurag Kumar Vulisha <anurag.kumar.vulisha(a)xilinx.com> who implemented a very similar fix to this issue.

[RHEL 8.2 PATCH] KVM: PPC: Book3S HV: XIVE: Ensure VP isn't already in use

by Daniel Henrique Barboza

From: Greg Kurz <groug(a)kaod.org> Bugzilla: 804424 Brew: 26599344 Upstream: Yes Tested: sanity tests in a Power 8 host Conflicts: none Connecting a vCPU to a XIVE KVM device means establishing a 1:1 association between a vCPU id and the offset (VP id) of a VP structure within a fixed size block of VPs. We currently try to enforce the 1:1 relationship by checking that a vCPU with the same id isn't already connected. This is good but unfortunately not enough because we don't map VP ids to raw vCPU ids but to packed vCPU ids, and the packing function kvmppc_pack_vcpu_id() isn't bijective by design. We got away with it because QEMU passes vCPU ids that fit well in the packing pattern. But nothing prevents userspace to come up with a forged vCPU id resulting in a packed id collision which causes the KVM device to associate two vCPUs to the same VP. This greatly confuses the irq layer and ultimately crashes the kernel, as shown below. Example: a guest with 1 guest thread per core, a core stride of 8 and 300 vCPUs has vCPU ids 0,8,16...2392. If QEMU is patched to inject at some point an invalid vCPU id 348, which is the packed version of itself and 2392, we get: genirq: Flags mismatch irq 199. 00010000 (kvm-2-2392) vs. 00010000

[PATCH 3/3] ext4: fix potential race between s_flex_groups online resizing and access

by Suraj Jitindar Singh

During an online resize an array of s_flex_groups structures gets replaced so it can get enlarged. If there is a concurrent access to the array and this memory has been reused then this can lead to an invalid memory access. The s_flex_group array has been converted into an array of pointers rather than an array of structures. This is to ensure that the information contained in the structures cannot get out of sync during a resize due to an accessor updating the value in the old structure after it has been copied but before the array pointer is updated. Since the structures them- selves are no longer copied but only the pointers to them this case is mitigated.

[PATCH v4 01/14] drm/i915: Fix sha_text population code

by Sean Paul

From: Sean Paul <seanpaul(a)chromium.org> This patch fixes a few bugs: 1- We weren't taking into account sha_leftovers when adding multiple ksvs to sha_text. As such, we were or'ing the end of ksv[j - 1] with the beginning of ksv[j] 2- In the sha_leftovers == 2 and sha_leftovers == 3 case, bstatus was being placed on the wrong half of sha_text, overlapping the leftover ksv value 3- In the sha_leftovers == 2 case, we need to manually terminate the byte stream with 0x80 since the hardware doesn't have enough room to add it after writing M0 The upside is that all of the HDCP supported HDMI repeaters I could find on Amazon just strip HDCP anyways, so it turns out to be _really_ hard to hit any of these cases without an MST hub, which is not (yet) supported. Oh, and the sha_leftovers == 1 case works perfectly!

mmc patches for v5.4.y, v5.5.y

by Guenter Roeck

Hi Greg, please apply the following two patches to v5.4.y and v5.5.y to fix a problem when trying to boot various pxa machines from MMC. d3a5bcb4a17f gpio: add gpiod_toggle_active_low() 9073d10b0989 mmc: core: Rework wp-gpio handling The second patch fixes the problem, the first patch is necessary for the second patch to compile. Background: Commit 9073d10b0989 claims "No functional changes intended". However, it does include the following functional code change. --- a/drivers/mmc/host/pxamci.c +++ b/drivers/mmc/host/pxamci.c @@ -740,16 +740,16 @@ static int pxamci_probe(struct platform_device *pdev) goto out; } + if (!host->pdata->gpio_card_ro_invert) + mmc->caps2 |= MMC_CAP2_RO_ACTIVE_HIGH; + ret = mmc_gpiod_request_ro(mmc, "wp", 0, 0, NULL); if (ret && ret != -ENOENT) { dev_err(dev, "Failed requesting gpio_ro\n"); goto out; } - if (!ret) { + if (!ret) host->use_ro_gpio = true; - mmc->caps2 |= host->pdata->gpio_card_ro_invert ? - 0 : MMC_CAP2_RO_ACTIVE_HIGH; - } This _is_ a functional change: Previously, if there was no "ro" gpio pin, caps2 was never updated to active-high. This can have the practical effect of making the the card read-only, thus preventing the system from booting if it was mounted (and expected to be mounted) read-write. This is seen when trying to boot "spitz" and similar qemu machines from mmc. I bisected the problem to commit c914a27c92f91 ("mmc: pxamci: Support getting GPIO descs for RO and WP), affecting v5.0 and later kernels. Thanks, Guenter

[PATCH v2] mtd: spi-nor: Fixup page size for S25FS-S

by Alexander A Sverdlin

From: Alexander Sverdlin <alexander.sverdlin(a)nokia.com> Spansion S25FS-S family has an issue in Basic Flash Parameter Table: DWORD-11 bits 7-4 specify write page size 512 bytes. In reality this is configurable in the non-volatile CR3NV register and even factory default configuration is "wrap at 256 bytes". So blind relying on BFPT breaks write operation on these Flashes. All this story is vendor-specific, so add the corresponding fixup hook which first restores the safe page size of 256 bytes from struct flash_info but checks is more performant 512 bytes configuration is active and adjusts the page_size accordingly.

PT_MAX_FULL_LEVELS is used to size the arrays that track guest pages table information, i.e. using a "max levels" of 4 causes KVM to access garbage beyond the end of an array when querying state for level 5 entries. E.g. FNAME(gpte_changed) will read garbage and most likely return %true for a level 5 entry, soft-hanging the guest because FNAME(fetch) will restart the guest instead of creating SPTEs because it thinks the guest PTE has changed. Note, KVM doesn't yet support 5-level nested EPT, so PT_MAX_FULL_LEVELS gets to stay "4" for the PTTYPE_EPT case. Fixes: 855feb673640 ("KVM: MMU: Add 5 level EPT & Shadow page table support.")

FAILED: patch "[PATCH] Btrfs: fix race between shrinking truncate and fiemap" failed to apply to 4.19-stable tree

This is generally harmless and at the moment the only consequences are missing file extent items representing holes after we expand the file size again after the truncate operation removed the prealloc extent items, and stale information for future fiemap calls (reporting extents that no longer exist or may have been reallocated to other files for example). Consider the following example: 1) Our inode has a size of 128KiB, one 128KiB extent at file offset 0 and a 1MiB prealloc extent at file offset 128KiB; 2) Task A starts doing a shrinking truncate of our inode to reduce it to a size of 64KiB. Before it searches the subvolume tree for file extent items to delete, it drops all the extent maps in the range from 64KiB to (u64)-1 by calling btrfs_drop_extent_cache(); 3) Task B starts doing a fiemap against our inode. When looking up for the inode's extent maps in the range from 128KiB to (u64)-1, it doesn't find any in the inode's extent map tree, since they were removed by task A. Because it didn't find any in the extent map tree, it scans the inode's subvolume tree for file extent items, and it finds the 1MiB prealloc extent at file offset 128KiB, then it creates an extent map based on that file extent item and adds it to inode's extent map tree (this ends up being done by btrfs_get_extent() <- btrfs_get_extent_fiemap() <- get_extent_skip_holes()); 4) Task A then drops the prealloc extent at file offset 128KiB and shrinks the 128KiB extent file offset 0 to a length of 64KiB. The truncation operation finishes and we end up with an extent map representing a 1MiB prealloc extent at file offset 128KiB, despite we don't have any more that extent; After this the two types of problems we have are: 1) Future calls to fiemap always report that a 1MiB prealloc extent exists at file offset 128KiB. This is stale information, no longer correct; 2) If the size of the file is increased, by a truncate operation that increases the file size or by a write into a file offset > 64KiB for example, we end up not inserting file extent items to represent holes for any range between 128KiB and 128KiB + 1MiB, since the hole expansion function, btrfs_cont_expand() will skip hole insertion for any range for which an extent map exists that represents a prealloc extent. This causes fsck to complain about missing file extent items when not using the NO_HOLES feature. The second issue could be often triggered by test case generic/561 from fstests, which runs fsstress and duperemove in parallel, and duperemove does frequent fiemap calls. Essentially the problems happens because fiemap does not acquire the inode's lock while truncate does, and fiemap locks the file range in the inode's iotree while truncate does not. So fix the issue by making btrfs_truncate_inode_items() lock the file range from the new file size to (u64)-1, so that it serializes with fiemap.

Random memory corruption may occur due to incorrent tlb flushes

by Santosh Sivaraj

Hi Greg/Sasha, The commit a46cc7a90fd (powerpc/mm/radix: Improve TLB/PWC flushes) picked up in 4.14 release has the potential to cause random memory corruption. This was fixed in 5.5 by the following patches. 12e4d53f3f powerpc/mmu_gather: enable RCU_TABLE_FREE even for !SMP case 0ed1325967 mm/mmu_gather: invalidate TLB correctly on batch allocation failure and flush 0758cd8304 asm-generic/tlb: avoid potential double flush It's a bit tricky to backport to 4.14 stable (though I have a backport to 4.19 stable, which I will post shortly). If you think it's important to fix this in 4.14, it would easier to revert the above mentioned commit (a46cc7a90fd). Please let me know your thoughts. Thanks, Santosh

[PATCH resend] mm, memcg: reset memcg's memory.{min, low} for reclaiming itself

by Yafang Shao

memory.{emin, elow} are set in mem_cgroup_protected(), and the values of them won't be changed until next recalculation in this function. After either or both of them are set, the next reclaimer to relcaim this memcg may be a different reclaimer, e.g. this memcg is also the root memcg of the new reclaimer, and then in mem_cgroup_protection() in get_scan_count() the old values of them will be used to calculate scan count, that is not proper. We should reset them to zero in this case. Here's an example of this issue. root_mem_cgroup / A memory.max=1024M memory.min=512M memory.current=800M Once kswapd is waked up, it will try to scan all MEMCGs, including this A, and it will assign memory.emin of A with 512M. After that, A may reach its hard limit(memory.max), and then it will do memcg reclaim. Because A is the root of this reclaimer, so it will not calculate its memory.emin. So the memory.emin is the old value 512M, and then this old value will be used in mem_cgroup_protection() in get_scan_count() to get the scan count. That is not proper.

[PATCH 4.19 1/2] jbd2: move the clearing of b_modified flag to the journal_unmap_buffer()

by zhangyi (F)

[ Upstream commit 6a66a7ded12baa6ebbb2e3e82f8cb91382814839 ] There is no need to delay the clearing of b_modified flag to the transaction committing time when unmapping the journalled buffer, so just move it to the journal_unmap_buffer().
