[PATCH v3 0/6] KVM: my debug patch queue

by Maxim Levitsky

Hi! I would like to publish two debug features which were needed for other stuff I work on. One is the reworked lx-symbols script which now actually works on at least gdb 9.1 (gdb 9.2 was reported to fail to load the debug symbols from the kernel for some reason, not related to this patch) and upstream qemu. The other feature is the ability to trap all guest exceptions (on SVM for now) and see them in kvmtrace prior to potential merge to double/triple fault. This can be very useful and I already had to manually patch KVM a few times for this. I will, once time permits, implement this feature on Intel as well. V2: * Some more refactoring and workarounds for lx-symbols script * added KVM_GUESTDBG_BLOCKIRQ flag to enable 'block interrupts on single step' together with KVM_CAP_SET_GUEST_DEBUG2 capability to indicate which guest debug flags are supported. This is a replacement for unconditional block of interrupts on single step that was done in previous version of this patch set. Patches to qemu to use that feature will be sent soon. * Reworked the the 'intercept all exceptions for debug' feature according to the review feedback: - renamed the parameter that enables the feature and moved it to common kvm module. (only SVM part is currently implemented though) - disable the feature for SEV guests as was suggested during the review - made the vmexit table const again, as was suggested in the review as well. V3: * Modified a selftest to cover the KVM_GUESTDBG_BLOCKIRQ * Rebased on kvm/queue Best regards, Maxim Levitsky Maxim Levitsky (6): KVM: SVM: split svm_handle_invalid_exit KVM: x86: add force_intercept_exceptions_mask KVM: SVM: implement force_intercept_exceptions_mask scripts/gdb: rework lx-symbols gdb script KVM: x86: implement KVM_GUESTDBG_BLOCKIRQ KVM: selftests: test KVM_GUESTDBG_BLOCKIRQ Documentation/virt/kvm/api.rst | 1 + arch/x86/include/asm/kvm_host.h | 5 +- arch/x86/include/uapi/asm/kvm.h | 1 + arch/x86/kvm/svm/svm.c | 87 +++++++- arch/x86/kvm/svm/svm.h | 6 +- arch/x86/kvm/x86.c | 12 +- arch/x86/kvm/x86.h | 2 + kernel/module.c | 8 +- scripts/gdb/linux/symbols.py | 203 ++++++++++++------ .../testing/selftests/kvm/x86_64/debug_regs.c | 24 ++- 10 files changed, 266 insertions(+), 83 deletions(-) -- 2.26.3

[PATCH] net: netdevsim: fix byte order on ipsec debugfs file

by Kleber Sacilotto de Souza

When adding a new xfrm state, the data provided via struct xfrm_state is stored in network byte order. This needs to be taken into consideration when exporting the SAs data to userspace via debugfs, otherwise the content will depend on the system endianness. Fix this by converting all multi-byte fields from network to host order. Also fix the selftest script which was expecting the data as exported by a little-endian system, which was inverted.
