Felix Fietkau 3848e6a246 kernel: crashlog: Avoid out-of-bounds write ... vsnprintf returns the number of chars that would have been written, not the actual number of chars written. This can lead to crashlog_buf->len being too big which in turn can lead to get_maxlen() returning negative numbers. The length argument of kmsg_dump_get_buffer will be casted to a size_t which makes a negative input a big positive number allowing kmsg_dump_get_buffer to write out of bounds. Fix this by using vscnprintf which returns the actually written number of chars. Signed-off-by: Helmut Schaa <helmut.schaa@googlemail.com> SVN-Revision: 37820		11 years ago
