[PATCH 0/2] KVM: fix overflow of zero page refcount with ksm running

by Zhuang Yanying

From: LinFeng <linfeng23(a)huawei.com> We found that the !is_zero_page() in kvm_is_mmio_pfn() was submmited in commit:90cff5a8cc("KVM: check for !is_zero_pfn() in kvm_is_mmio_pfn()"), but reverted in commit:0ef2459983("kvm: fix kvm_is_mmio_pfn() and rename to kvm_is_reserved_pfn()"). Maybe just adding !is_zero_page() to kvm_is_reserved_pfn() is too rough. According to commit:e433e83bc3("KVM: MMU: Do not treat ZONE_DEVICE pages as being reserved"), special handling in some other flows is also need by zero_page, if we would treat zero_page as being reserved. Well, as fixing all functions reference to kvm_is_reserved_pfn() in this patch, we found that only kvm_release_pfn_clean() and kvm_get_pfn() don't need special handling. So, we thought why not only check is_zero_page() in before get and put page, and revert our last commit:31e813f38f("KVM: fix overflow of zero page refcount with ksm running") in master. Instead of adding !is_zero_page() in kvm_is_reserved_pfn(), new idea is as follow: diff --git a/virt/kvm/kvm_main.c b/virt/kvm/kvm_main.c index 7f9ee2929cfe..f9a1f9cf188e 100644 --- a/virt/kvm/kvm_main.c +++ b/virt/kvm/kvm_main.c @@ -1695,7 +1695,8 @@ EXPORT_SYMBOL_GPL(kvm_release_page_clean); void kvm_release_pfn_clean(kvm_pfn_t pfn) { - if (!is_error_noslot_pfn(pfn) && !kvm_is_reserved_pfn(pfn)) + if (!is_error_noslot_pfn(pfn) && + (!kvm_is_reserved_pfn(pfn) || is_zero_pfn(pfn))) put_page(pfn_to_page(pfn)); } EXPORT_SYMBOL_GPL(kvm_release_pfn_clean); @@ -1734,7 +1735,7 @@ EXPORT_SYMBOL_GPL(kvm_set_pfn_accessed); void kvm_get_pfn(kvm_pfn_t pfn) { - if (!kvm_is_reserved_pfn(pfn)) + if (!kvm_is_reserved_pfn(pfn) || is_zero_pfn(pfn)) get_page(pfn_to_page(pfn)); } EXPORT_SYMBOL_GPL(kvm_get_pfn); We are confused why ZONE_DEVICE not do this, but treating it as no reserved. Is it racy if we change only use the patch in cover letter, but not the series patches. And we check the code of v4.9.y v4.10.y v4.11.y v4.12.y, this bug exists in v4.11.y and later, but not in v4.9.y v4.10.y or before. After commit:e86c59b1b1("mm/ksm: improve deduplication of zero pages with colouring"), ksm will use zero pages with colouring. This feature was added in v4.11.y, so I wonder why v4.9.y has this bug. We use crash tools attaching to /proc/kcore to check the refcount of zero_page, then create and destroy vm. The refcount stays at 1 on v4.9.y, well it increases only after v4.11.y. Are you sure it is the same bug you run into? Is there something we missing?

[PATCH 1/4] powerpc/xive: Use XIVE_BAD_IRQ instead of zero to catch non configured IPIs

by Cédric Le Goater

When a CPU is brought up, an IPI number is allocated and recorded under the XIVE CPU structure. Invalid IPI numbers are tracked with interrupt number 0x0. On the PowerNV platform, the interrupt number space starts at 0x10 and this works fine. However, on the sPAPR platform, it is possible to allocate the interrupt number 0x0 and this raises an issue when CPU 0 is unplugged. The XIVE spapr driver tracks allocated interrupt numbers in a bitmask and it is not correctly updated when interrupt number 0x0 is freed. It stays allocated and it is then impossible to reallocate. Fix by using the XIVE_BAD_IRQ value instead of zero on both platforms.

[PATCH v2 1/3] ACPI: fix: Update Tiger Lake ACPI device IDs

by Gayatri Kammela

AW: [PATCH Backport to stable/linux-4.14.y] make 'user_access_begin()' do 'access_ok()'

by Schmid, Carsten

>> >> Fixes CVE-2018-20669 >> Backported from v5.0-rc1 >> Patch 1/1 > > Also, that cve was "supposed" to already be fixed in the 4.19.13 kernel > release for some reason, and it's a drm issue, not a core access_ok() > issue. > > So why is this needed for 4.14? > See https://access.redhat.com/security/cve/cve-2018-20669 Looks like Linus' fix was attacking this at the root cause, not only for DRM. Also, i use https://www.linuxkernelcves.com/ as a research source, and they claim that CVE not fixed in 4.19. (and i'll check for the other LTS kernels as well) >> >> Signed-off-by: Linus Torvalds <torvalds(a)linux-foundation.org> > > No s-o-by from you? Ops. Will add this in a resend. >> Want to give this work back to the community, as 4.14 is a SLTS. > > What is "SLTS"? Super Long Term Supported kernel - thanks to guys like you :-) 4.14 really is that (Jan. 2024, as of https://www.kernel.org/category/releases.html) > > thanks, > > greg k-h Thanks, and i have some other patches backported to 4.14 as CVE fixes, which i'll propose in the next hours.

[PATCH Backport to stable/linux-4.14.y] make 'user_access_begin()' do 'access_ok()'

by Schmid, Carsten

>From eb5a13ddc30824c20f1e2b662d2c821ad3808526 Mon Sep 17 00:00:00 2001 From: Linus Torvalds <torvalds(a)linux-foundation.org> Date: Fri, 4 Jan 2019 12:56:09 -0800 Subject: [PATCH] make 'user_access_begin()' do 'access_ok()' [ Upstream commit 594cc251fdd0d231d342d88b2fdff4bc42fb0690 ] Fixes CVE-2018-20669 Backported from v5.0-rc1 Patch 1/1 Originally, the rule used to be that you'd have to do access_ok() separately, and then user_access_begin() before actually doing the direct (optimized) user access. But experience has shown that people then decide not to do access_ok() at all, and instead rely on it being implied by other operations or similar. Which makes it very hard to verify that the access has actually been range-checked. If you use the unsafe direct user accesses, hardware features (either SMAP - Supervisor Mode Access Protection - on x86, or PAN - Privileged Access Never - on ARM) do force you to use user_access_begin(). But nothing really forces the range check. By putting the range check into user_access_begin(), we actually force people to do the right thing (tm), and the range check vill be visible near the actual accesses. We have way too long a history of people trying to avoid them. Signed-off-by: Linus Torvalds <torvalds(a)linux-foundation.org> --- Rationale: When working on stability and security for a project with 4.14 kernel, i backported patches from upstream.

patch "driver core: platform: Initialize dma_parms for platform devices" added to char-misc-testing

by gregkh＠linuxfoundation.org

This is a note to let you know that I've just added the patch titled driver core: platform: Initialize dma_parms for platform devices to my char-misc git tree which can be found at git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/char-misc.git in the char-misc-testing branch. The patch will show up in the next release of the linux-next tree (usually sometime within the next 24 hours during the week.) The patch will be merged to the char-misc-next branch sometime soon, after it passes testing, and the merge window is open. If you have any questions about this process, please let me know. >From 7c8978c0837d40c302f5e90d24c298d9ca9fc097 Mon Sep 17 00:00:00 2001 From: Ulf Hansson <ulf.hansson(a)linaro.org> Date: Wed, 25 Mar 2020 12:34:06 +0100 Subject: driver core: platform: Initialize dma_parms for platform devices It's currently the platform driver's responsibility to initialize the pointer, dma_parms, for its corresponding struct device. The benefit with this approach allows us to avoid the initialization and to not waste memory for the struct device_dma_parameters, as this can be decided on a case by case basis. However, it has turned out that this approach is not very practical. Not only does it lead to open coding, but also to real errors. In principle callers of dma_set_max_seg_size() doesn't check the error code, but just assumes it succeeds. For these reasons, let's do the initialization from the common platform bus at the device registration point. This also follows the way the PCI devices are being managed, see pci_device_add().

[PATCH v2] modpost: move the namespace field in Module.symvers last

by Jessica Yu

In order to preserve backwards compatability with kmod tools, we have to move the namespace field in Module.symvers last, as the depmod -e -E option looks at the first three fields in Module.symvers to check symbol versions (and it's expected they stay in the original order of crc, symbol, module). In addition, update an ancient comment above read_dump() in modpost that suggested that the export type field in Module.symvers was optional. I suspect that there were historical reasons behind that comment that are no longer accurate. We have been unconditionally printing the export type since 2.6.18 (commit bd5cbcedf44), which is over a decade ago now. Fix up read_dump() to treat each field as non-optional. I suspect the original read_dump() code treated the export field as optional in order to support pre <= 2.6.18 Module.symvers (which did not have the export type field). Note that although symbol namespaces are optional, the field will not be omitted from Module.symvers if a symbol does not have a namespace. In this case, the field will simply be empty and the next delimiter or end of line will follow.
