The most trivial example of a race condition can be demonstrated by this sequence where mm_list contains just one entry: CPU A CPU B -> sgx_release() -> sgx_mmu_notifier_release() -> list_del_rcu() <- list_del_rcu() -> kref_put() -> sgx_encl_release() -> synchronize_srcu() -> cleanup_srcu_struct() A sequence similar to this has also been spotted in tests under high stress: [ +0.000008] WARNING: CPU: 3 PID: 7620 at kernel/rcu/srcutree.c:374 cleanup_srcu_struct+0xed/0x100 Albeit not spotted in the tests, it's also entirely possible that the following scenario could happen: CPU A CPU B -> sgx_release() -> sgx_mmu_notifier_release() -> list_del_rcu() -> kref_put() -> sgx_encl_release() -> cleanup_srcu_struct() <- cleanup_srcu_struct() -> synchronize_srcu() This scenario would lead into use-after free in cleaup_srcu_struct(). Fix this by taking a reference to the enclave in sgx_mmu_notifier_release().

[PATCH v2] x86/apic/of: Fix CPU devicetree-node lookups

by Johan Hovold

Architectures that describe the CPU topology in devicetree and that do not have an identity mapping between physical and logical CPU ids need to override the default implementation of arch_match_cpu_phys_id(). Failing to do so breaks CPU devicetree-node lookups using of_get_cpu_node() and of_cpu_device_node_get() which several drivers rely on. It also causes the CPU struct devices exported through sysfs to point to the wrong devicetree nodes. On x86, CPUs are described in devicetree using their APIC ids and those do not generally coincide with the logical ids, even if CPU0 typically uses APIC id 0. Add the missing implementation of arch_match_cpu_phys_id() so that CPU-node lookups work also with SMP. Apart from fixing the broken sysfs devicetree-node links this likely do not affect users of mainline kernels as the above mentioned drivers are currently not used on x86 as far as I know. Fixes: 4e07db9c8db8 ("x86/devicetree: Use CPU description from Device Tree") Cc: stable <stable(a)vger.kernel.org> # 4.17 Signed-off-by: Johan Hovold <johan(a)kernel.org> --- Thomas, Hope this looks better to you. My use case for this is still out-of-tree, but since CPU-node lookup is generic functionality and with observable impact also for mainline users (sysfs) I added a stable tag.

[PATCH] nvme-pci: add quirk to make Kingston A2000 SSD avoid deepest sleep state

by Thorsten Leemhuis

Some Kingston A2000 NVMe SSDs sooner or later get confused and stop working when they use the deepest APST sleep while running Linux. The system then crashes and one has to cold boot it to get the SSD working again. Kingston seems to known about this since at least mid-September 2020: https://bbs.archlinux.org/viewtopic.php?pid=1926994#p1926994 Someone working for a German company representing Kingston to the German press confirmed to me Kingston engineering is aware of the issue and investigating; the person stated that to their current knowledge only the deepest APST sleep state causes trouble. Therefore, make Linux avoid it for now by applying the NVME_QUIRK_NO_DEEPEST_PS to this SSD. I have two such SSDs, but it seems the problem doesn't occur with them. I hence couldn't verify if this patch really fixes the problem, but all the data in front of me suggests it should. This patch can easily be reverted or improved upon if a better solution surfaces. FWIW, there are many reports about the issue scattered around the web; most of the users disabled APST completely to make things work, some just made Linux avoid the deepest sleep state: https://bugzilla.kernel.org/show_bug.cgi?id=195039#c65 https://bugzilla.kernel.org/show_bug.cgi?id=195039#c73 https://bugzilla.kernel.org/show_bug.cgi?id=195039#c74 https://bugzilla.kernel.org/show_bug.cgi?id=195039#c78 https://bugzilla.kernel.org/show_bug.cgi?id=195039#c79 https://bugzilla.kernel.org/show_bug.cgi?id=195039#c80 https://askubuntu.com/questions/1222049/nvmekingston-a2000-sometimes-stops-… https://community.acer.com/en/discussion/604326/m-2-nvme-ssd-aspire-517-51g… For the record, some data from 'nvme id-ctrl /dev/nvme0' NVME Identify Controller: vid : 0x2646 ssvid : 0x2646 mn : KINGSTON SA2000M81000G fr : S5Z42105 [...] ps 0 : mp:9.00W operational enlat:0 exlat:0 rrt:0 rrl:0 rwt:0 rwl:0 idle_power:- active_power:- ps 1 : mp:4.60W operational enlat:0 exlat:0 rrt:1 rrl:1 rwt:1 rwl:1 idle_power:- active_power:- ps 2 : mp:3.80W operational enlat:0 exlat:0 rrt:2 rrl:2 rwt:2 rwl:2 idle_power:- active_power:- ps 3 : mp:0.0450W non-operational enlat:2000 exlat:2000 rrt:3 rrl:3 rwt:3 rwl:3 idle_power:- active_power:- ps 4 : mp:0.0040W non-operational enlat:15000 exlat:15000 rrt:4 rrl:4 rwt:4 rwl:4 idle_power:- active_power:- Cc: stable(a)vger.kernel.org # 4.14+ Signed-off-by: Thorsten Leemhuis <linux(a)leemhuis.info> --- Once this is out I will post a link to it in https://bugzilla.kernel.org/show_bug.cgi?id=195039, maybe someone there might be able to confirm that this fixes the issue. --- drivers/nvme/host/pci.c | 2 ++ 1 file changed, 2 insertions(+) diff --git a/drivers/nvme/host/pci.c b/drivers/nvme/host/pci.c index 856aa31931c1..421735e16870 100644 --- a/drivers/nvme/host/pci.c +++ b/drivers/nvme/host/pci.c @@ -3257,6 +3257,8 @@ static const struct pci_device_id nvme_id_table[] = { .driver_data = NVME_QUIRK_DISABLE_WRITE_ZEROES, }, { PCI_DEVICE(0x15b7, 0x2001), /* Sandisk Skyhawk */ .driver_data = NVME_QUIRK_DISABLE_WRITE_ZEROES, }, + { PCI_DEVICE(0x2646, 0x2263), /* KINGSTON A2000 NVMe SSD */ + .driver_data = NVME_QUIRK_NO_DEEPEST_PS, }, { PCI_DEVICE(PCI_VENDOR_ID_APPLE, 0x2001), .driver_data = NVME_QUIRK_SINGLE_VECTOR }, { PCI_DEVICE(PCI_VENDOR_ID_APPLE, 0x2003) }, -- 2.29.2

[PATCH v4 0/2] mm: fix initialization of struct page for holes in memory layout

by Mike Rapoport

From: Mike Rapoport <rppt(a)linux.ibm.com> Hi, Commit 73a6e474cb37 ("mm: memmap_init: iterate over memblock regions rather that check each PFN") exposed several issues with the memory map initialization and these patches fix those issues. Initially there were crashes during compaction that Qian Cai reported back in April [1]. It seemed back then that the problem was fixed, but a few weeks ago Andrea Arcangeli hit the same bug [2] and there was an additional discussion at [3]. I didn't appreciate variety of ways BIOSes can report memory in the first megabyte, so v3 of this set caused boot failures on several x86 systems. Hopefully this time I covered all the bases. The first patch here complements commit bde9cfa3afe4 ("x86/setup: don't remove E820_TYPE_RAM for pfn 0") for the cases when BIOS reports the first page as absent or reserved. The second patch is a more robust version of d3921cb8be29 ("mm: fix initialization of struct page for holes in memory layout") that can now handle the above cases as well. v4: * make sure pages in the range 0 - start_pfn_of_lowest_zone are initialized even if an architecture hides them from the generic mm * finally make pfn 0 on x86 to be a part of memory visible to the generic mm as reserved memory. v3: https://lore.kernel.org/lkml/20210111194017.22696-1-rppt@kernel.org * use architectural zone constraints to set zone links for struct pages corresponding to the holes * drop implicit update of memblock.memory * add a patch that sets pfn 0 to E820_TYPE_RAM on x86 v2: https://lore.kernel.org/lkml/20201209214304.6812-1-rppt@kernel.org/): * added patch that adds all regions in memblock.reserved that do not overlap with memblock.memory to memblock.memory in the beginning of free_area_init() [1] https://lore.kernel.org/lkml/8C537EB7-85EE-4DCF-943E-3CC0ED0DF56D@lca.pw [2] https://lore.kernel.org/lkml/20201121194506.13464-1-aarcange@redhat.com [3] https://lore.kernel.org/mm-commits/20201206005401.qKuAVgOXr%akpm@linux-foun… Mike Rapoport (2): x86/setup: always add the beginning of RAM as memblock.memory mm: fix initialization of struct page for holes in memory layout arch/x86/kernel/setup.c | 8 ++++ mm/page_alloc.c | 85 ++++++++++++++++++++++++----------------- 2 files changed, 59 insertions(+), 34 deletions(-) -- 2.28.0

[PATCH 01/11] x86/fault: Fix AMD erratum #91 errata fixup for user code

by Andy Lutomirski

The recent rework of probe_kernel_read() and its conversion to get_kernel_nofault() inadvertently broke is_prefetch(). We were using probe_kernel_read() as a sloppy "read user or kernel memory" helper, but it doens't do that any more. The new get_kernel_nofault() reads *kernel* memory only, which completely broke is_prefetch() for user access. Adjust the code to the the correct accessor based on access mode. The manual address bounds check is no longer necessary, since the accessor helpers (get_user() / get_kernel_nofault()) do the right thing all by themselves. As a bonus, by using the correct accessor, we don't need the open-coded address bounds check. While we're at it, disable the workaround on all CPUs except AMD Family 0xF. By my reading of the Revision Guide for AMD Athlon™ 64 and AMD Opteron™ Processors, only family 0xF is affected.

Since ARCH_CAPABILITIES is unconditionally emulated by KVM, wouldn't it make sense to unconditionally expose TSX_CTRL as well, as opposed to exposing it only if it's supported in the host? I.e. allow migrating a TSX-disabled guest to a host without TSX.
