[PATCH v2 0/6] Enhance event delivery error handling

by Ivan Orlov

Currently, the situation when guest accesses MMIO during vectoring is handled differently on VMX and SVM: on VMX KVM returns internal error, when SVM goes into infinite loop trying to deliver an event again and again. This patch series eliminates this difference by returning a KVM internal error when guest performs MMIO during vectoring for both VMX and SVM. Also, introduce a selftest test case which covers the error handling mentioned above. V1 -> V2: - Make commit messages more brief, avoid using pronouns - Extract SVM error handling into a separate commit - Introduce a new X86EMUL_ return type and detect the unhandleable vectoring error in vendor-specific check_emulate_instruction instead of handling it in the common MMU code (which is specific for cached MMIO) Ivan Orlov (6): KVM: x86: Add function for vectoring error generation KVM: x86: Add emulation status for vectoring during MMIO KVM: VMX: Handle vectoring error in check_emulate_instruction KVM: SVM: Handle MMIO during vectroing error selftests: KVM: extract lidt into helper function selftests: KVM: Add test case for MMIO during vectoring arch/x86/include/asm/kvm_host.h | 12 ++++- arch/x86/kvm/kvm_emulate.h | 2 + arch/x86/kvm/svm/svm.c | 9 +++- arch/x86/kvm/vmx/vmx.c | 33 +++++------- arch/x86/kvm/x86.c | 27 ++++++++++ .../selftests/kvm/include/x86_64/processor.h | 7 +++ .../selftests/kvm/set_memory_region_test.c | 53 ++++++++++++++++++- .../selftests/kvm/x86_64/sev_smoke_test.c | 2 +- 8 files changed, 119 insertions(+), 26 deletions(-) -- 2.43.0

[PATCH 00/15] KVM: x86: Introduce new ioctl KVM_TRANSLATE2

by Nikolas Wipper

This series introduces a new ioctl KVM_TRANSLATE2, which expands on KVM_TRANSLATE. It is required to implement Hyper-V's HvTranslateVirtualAddress hyper-call as part of the ongoing effort to emulate HyperV's Virtual Secure Mode (VSM) within KVM and QEMU. The hyper- call requires several new KVM APIs, one of which is KVM_TRANSLATE2, which implements the core functionality of the hyper-call. The rest of the required functionality will be implemented in subsequent series. Other than translating guest virtual addresses, the ioctl allows the caller to control whether the access and dirty bits are set during the page walk. It also allows specifying an access mode instead of returning viable access modes, which enables setting the bits up to the level that caused a failure. Additionally, the ioctl provides more information about why the page walk failed, and which page table is responsible. This functionality is not available within KVM_TRANSLATE, and can't be added without breaking backwards compatiblity, thus a new ioctl is required. The ioctl was designed to facilitate as many other use cases as possible apart from VSM. The error codes were intentionally chosen to be broad enough to avoid exposing architecture specific details. Even though HvTranslateVirtualAddress only really needs one flag to set the accessed and dirty bits whenever possible, that was split into several flags so that future users can chose more gradually when these bits should be set. Furthermore, as much information as possible is provided to the caller. The patch series includes selftests for the ioctl, as well as fuzzy testing on random garbage guest page table entries. All previously passing KVM selftests and KVM unit tests still pass. Series overview: - 1: Document the new ioctl - 2-11: Update the page walker in preparation - 12-14: Implement the ioctl - 15: Implement testing This series, alongside the series by Nicolas Saenz Julienne [1] introducing the core building blocks for VSM and the accompanying QEMU implementation [2], is capable of booting Windows Server 2019.

[PATCH v2 0/4] Migrate PCI Endpoint Subsystem tests to Kselftest

by Manivannan Sadhasivam

Hi, This series carries forward the effort to add Kselftest for PCI Endpoint Subsystem started by Aman Gupta [1] a while ago. I reworked the initial version based on another patch that fixes the return values of IOCTLs in pci_endpoint_test driver and did many cleanups. Since the resulting work modified the initial version substantially, I took over the authorship. This series also incorporates the review comment by Shuah Khan [2] to move the existing tests from 'tools/pci' to 'tools/testing/kselftest/pci_endpoint' before migrating to Kselftest framework. I made sure that the tests are executable in each commit and updated documentation accordingly. NOTE: Patch 1 is strictly not related to this series, but necessary to execute Kselftests with Qualcomm Endpoint devices. So this can be merged separately. - Mani [1] https://lore.kernel.org/linux-pci/20221007053934.5188-1-aman1.gupta@samsung… [2] https://lore.kernel.org/linux-pci/b2a5db97-dc59-33ab-71cd-f591e0b1b34d@linu… Changes in v2: * Added a patch that fixes return values of IOCTL in pci_endpoint_test driver * Moved the existing tests to new location before migrating * Added a fix for BARs on Qcom devices * Updated documentation and also added fixture variants for memcpy & DMA modes Manivannan Sadhasivam (4): PCI: qcom-ep: Mark BAR0/BAR2 as 64bit BARs and BAR1/BAR3 as RESERVED misc: pci_endpoint_test: Fix the return value of IOCTL selftests: Move PCI Endpoint tests from tools/pci to Kselftests selftests: pci_endpoint: Migrate to Kselftest framework Documentation/PCI/endpoint/pci-test-howto.rst | 144 +++------- MAINTAINERS | 2 +- drivers/misc/pci_endpoint_test.c | 236 ++++++++--------- drivers/pci/controller/dwc/pcie-qcom-ep.c | 4 + tools/pci/Build | 1 - tools/pci/Makefile | 58 ---- tools/pci/pcitest.c | 250 ------------------ tools/pci/pcitest.sh | 72 ----- tools/testing/selftests/Makefile | 1 + .../testing/selftests/pci_endpoint/.gitignore | 2 + tools/testing/selftests/pci_endpoint/Makefile | 7 + tools/testing/selftests/pci_endpoint/config | 4 + .../pci_endpoint/pci_endpoint_test.c | 186 +++++++++++++ 13 files changed, 365 insertions(+), 602 deletions(-) delete mode 100644 tools/pci/Build delete mode 100644 tools/pci/Makefile delete mode 100644 tools/pci/pcitest.c delete mode 100644 tools/pci/pcitest.sh create mode 100644 tools/testing/selftests/pci_endpoint/.gitignore create mode 100644 tools/testing/selftests/pci_endpoint/Makefile create mode 100644 tools/testing/selftests/pci_endpoint/config create mode 100644 tools/testing/selftests/pci_endpoint/pci_endpoint_test.c -- 2.25.1

[PATCH net-next v4 0/6] tls: implement key updates for TLS1.3

by Sabrina Dubroca

This adds support for receiving KeyUpdate messages (RFC 8446, 4.6.3 [1]). A sender transmits a KeyUpdate message and then changes its TX key. The receiver should react by updating its RX key before processing the next message. This patchset implements key updates by: 1. pausing decryption when a KeyUpdate message is received, to avoid attempting to use the old key to decrypt a record encrypted with the new key 2. returning -EKEYEXPIRED to syscalls that cannot receive the KeyUpdate message, until the rekey has been performed by userspace 3. passing the KeyUpdate message to userspace as a control message 4. allowing updates of the crypto_info via the TLS_TX/TLS_RX setsockopts This API has been tested with gnutls to make sure that it allows userspace libraries to implement key updates [2]. Thanks to Frantisek Krenzelok <fkrenzel(a)redhat.com> for providing the implementation in gnutls and testing the kernel patches. ======================================================================= Discussions around v2 of this patchset focused on how HW offload would interact with rekey. RX - The existing SW path will handle all records between the KeyUpdate message signaling the change of key and the new key becoming known to the kernel -- those will be queued encrypted, and decrypted in SW as they are read by userspace (once the key is provided, ie same as this patchset) - Call ->tls_dev_del + ->tls_dev_add immediately during setsockopt(TLS_RX) TX - After setsockopt(TLS_TX), switch to the existing SW path (not the current device_fallback) until we're able to re-enable HW offload - tls_device_sendmsg will call into tls_sw_sendmsg under lock_sock to avoid changing socket ops during the rekey while another thread might be waiting on the lock - We only re-enable HW offload (call ->tls_dev_add to install the new key in HW) once all records sent with the old key have been ACKed. At this point, all unacked records are SW-encrypted with the new key, and the old key is unused by both HW and retransmissions. - If there are no unacked records when userspace does setsockopt(TLS_TX), we can (try to) install the new key in HW immediately. - If yet another key has been provided via setsockopt(TLS_TX), we don't install intermediate keys, only the latest. - TCP notifies ktls of ACKs via the icsk_clean_acked callback. In case of a rekey, tls_icsk_clean_acked will record when all data sent with the most recent past key has been sent. The next call to sendmsg will install the new key in HW. - We close and push the current SW record before reenabling offload. If ->tls_dev_add fails to install the new key in HW, we stay in SW mode. We can add a counter to keep track of this. In addition: Because we can't change socket ops during a rekey, we'll also have to modify do_tls_setsockopt_conf to check ctx->tx_conf and only call either tls_set_device_offload or tls_set_sw_offload. RX already uses the same ops for both TLS_HW and TLS_SW, so we could switch between HW and SW mode on rekey. An alternative would be to have a common sendmsg which locks the socket and then calls the correct implementation. We'll need that anyway for the offload under rekey case, so that would only add a test to the SW path's ops (compared to the current code). That should allow us to simplify build_protos a bit, but might have a performance impact - we'll need to check it if we want to go that route. ======================================================================= Changes since v3: - rebase on top of net-next - rework tls_check_pending_rekey according to Jakub's feedback - add statistics for rekey: {RX,TX}REKEY{OK,ERROR} - some coding style clean ups Link: https://lore.kernel.org/netdev/cover.1691584074.git.sd@queasysnail.net/ [v3] Link: https://lore.kernel.org/netdev/cover.1676052788.git.sd@queasysnail.net/ [v2] Link: https://lore.kernel.org/netdev/cover.1673952268.git.sd@queasysnail.net/ [v1] Link: https://www.rfc-editor.org/rfc/rfc8446#section-4.6.3 [1] Link: https://gitlab.com/gnutls/gnutls/-/merge_requests/1625 [2] Sabrina Dubroca (6): tls: block decryption when a rekey is pending tls: implement rekey for TLS1.3 tls: add counters for rekey docs: tls: document TLS1.3 key updates selftests: tls: add key_generation argument to tls_crypto_info_init selftests: tls: add rekey tests Documentation/networking/tls.rst | 31 ++ include/net/tls.h | 3 + include/uapi/linux/snmp.h | 4 + net/tls/tls.h | 3 +- net/tls/tls_device.c | 2 +- net/tls/tls_main.c | 71 ++++- net/tls/tls_proc.c | 4 + net/tls/tls_sw.c | 138 +++++++-- tools/testing/selftests/net/tls.c | 480 +++++++++++++++++++++++++++++- 9 files changed, 676 insertions(+), 60 deletions(-) -- 2.47.0
