KVM: Fix stack-out-of-bounds read in write_mmio
CVE-2017-17741
This redefines the kvm_mmio trace event as follows:
TRACE_EVENT(kvm_mmio,
- TP_PROTO(int type, int len, u64 gpa, u64 val),
+ TP_PROTO(int type, int len, u64 gpa, void *val),
TP_ARGS(type, len, gpa, val),
..which is different from the lttng prototype in instrumentation/events
/lttng-module/kvm.h:
#if (LINUX_VERSION_CODE >= KERNEL_VERSION(4,15,0) \
|| LTTNG_KERNEL_RANGE(4,14,14, 4,15,0) \
|| LTTNG_KERNEL_RANGE(4,9,77, 4,10,0) \
|| LTTNG_KERNEL_RANGE(4,4,112, 4,5,0) \
|| LTTNG_KERNEL_RANGE(3,16,52, 3,17,0) \
|| LTTNG_KERNEL_RANGE(3,2,97, 3,3,0) \
|| LTTNG_DEBIAN_KERNEL_RANGE(4,9,65,0,3,0, 4,10,0,0,0,0))
LTTNG_TRACEPOINT_EVENT(kvm_mmio,
TP_PROTO(int type, int len, u64 gpa, void *val),
TP_ARGS(type, len, gpa, val),
TP_FIELDS(
ctf_integer(u32, type, type)
ctf_integer(u32, len, len)
ctf_integer(u64, gpa, gpa)
ctf_sequence_hex(unsigned char, val, val, u32, len)
)
)
#else
LTTNG_TRACEPOINT_EVENT(kvm_mmio,
TP_PROTO(int type, int len, u64 gpa, u64 val),
TP_ARGS(type, len, gpa, val),
TP_FIELDS(
ctf_integer(u32, type, type)
ctf_integer(u32, len, len)
ctf_integer(u64, gpa, gpa)
ctf_integer(u64, val, val)
)
)
Not sure how we #ifdef around this as the kernel version is 4.13 yet it now has
a 4.15 API
