[PATCH 08/11] KVM: SVM: move guest vmsave/vmload back to assembly

by Paolo Bonzini

FILL_RETURN_BUFFER can access percpu data, therefore vmload of the host save area must be executed first. First of all, move the VMCB vmsave/vmload to assembly, essentially undoing commit fb0c4a4fee5a ("KVM: SVM: move VMLOAD/VMSAVE to C code", 2021-03-15). The reason for that commit was that it made it simpler to use a different VMCB for VMLOAD/VMSAVE versus VMRUN; but that is not a big hassle anymore thanks to the kvm-asm-offsets machinery. The idea on how to number the exception tables is stolen from a prototype patch by Peter Zijlstra.

[PATCH 04/11] KVM: SVM: retrieve VMCB from assembly

by Paolo Bonzini

Continue moving all accesses to struct vcpu_svm directly in vmenter.S. This limits the confusion due to different registers used for argument passing in 32- and 64-bit ABIs. It is not strictly necessary for __svm_sev_es_vcpu_run, but staying consistent is a good idea since it makes __svm_sev_es_vcpu_run a stripped version of _svm_vcpu_run. No functional change intended.

[PATCH 01/11] KVM: x86: use a separate asm-offsets.c file

by Paolo Bonzini

This already removes the ugly #includes from asm-offsets.c, but especially it avoids a future error when asm-offsets will try to include svm/svm.h. This would not work for kernel/asm-offsets.c, because svm/svm.h includes kvm_cache_regs.h which is not in the include path when compiling asm-offsets.c. The problem is not there if the .c file is in arch/x86/kvm.

patch "binder: validate alloc->mm in ->mmap() handler" added to char-misc-linus

by gregkh＠linuxfoundation.org

This is a note to let you know that I've just added the patch titled binder: validate alloc->mm in ->mmap() handler 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-linus 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 hopefully also be merged in Linus's tree for the next -rc kernel release. If you have any questions about this process, please let me know. From 3ce00bb7e91cf57d723905371507af57182c37ef Mon Sep 17 00:00:00 2001 From: Carlos Llamas <cmllamas(a)google.com> Date: Fri, 4 Nov 2022 23:12:35 +0000 Subject: binder: validate alloc->mm in ->mmap() handler Since commit 1da52815d5f1 ("binder: fix alloc->vma_vm_mm null-ptr dereference") binder caches a pointer to the current->mm during open(). This fixes a null-ptr dereference reported by syzkaller. Unfortunately, it also opens the door for a process to update its mm after the open(), (e.g. via execve) making the cached alloc->mm pointer invalid. Things get worse when the process continues to mmap() a vma. From this point forward, binder will attempt to find this vma using an obsolete alloc->mm reference. Such as in binder_update_page_range(), where the wrong vma is obtained via vma_lookup(), yet binder proceeds to happily insert new pages into it. To avoid this issue fail the ->mmap() callback if we detect a mismatch between the vma->vm_mm and the original alloc->mm pointer. This prevents alloc->vm_addr from getting set, so that any subsequent vma_lookup() calls fail as expected.

[PATCH] usb: cdnsp: Fix issue with Clear Feature Halt Endpoint

by Pawel Laszczak

During handling Clear Halt Endpoint Feature request driver invokes Reset Endpoint command. Because this command has some issue with transition endpoint from Running to Idle state the driver must stop the endpoint by using Stop Endpoint command. cc: <stable(a)vger.kernel.org> Fixes: 3d82904559f4 ("usb: cdnsp: cdns3 Add main part of Cadence USBSSP DRD Driver") Signed-off-by: Pawel Laszczak <pawell(a)cadence.com> --- drivers/usb/cdns3/cdnsp-gadget.c | 12 ++++-------- drivers/usb/cdns3/cdnsp-ring.c | 3 ++- 2 files changed, 6 insertions(+), 9 deletions(-) diff --git a/drivers/usb/cdns3/cdnsp-gadget.c b/drivers/usb/cdns3/cdnsp-gadget.c index e2e7d16f43f4..0576f9b0e4aa 100644 --- a/drivers/usb/cdns3/cdnsp-gadget.c +++ b/drivers/usb/cdns3/cdnsp-gadget.c @@ -600,11 +600,11 @@ int cdnsp_halt_endpoint(struct cdnsp_device *pdev, trace_cdnsp_ep_halt(value ?
