pub fn extract_dmesg<P: PhysicalMemoryProvider>(
reader: &ObjectReader<P>,
) -> Result<Vec<DmesgEntry>>Expand description
Extract dmesg entries from the kernel ring buffer.
Looks up the log_buf symbol, dereferences the pointer to obtain the
buffer address, reads log_buf_len to determine buffer size, then
iterates printk_log records until len == 0 or the buffer is exhausted.
Returns an empty Vec if the log_buf symbol is not found (e.g., wrong
profile or non-Linux image).
ยงSafety limit
Caps extraction at 65,536 entries to prevent runaway iteration on corrupt data.
