__smc_diag_dump() is potentially copying uninitialized kernel stack memory into socket buffers, since the compiler may leave a 4-byte hole near the beginning of `struct smcd_diag_dmbinfo`. Fix it by initializing `dinfo` with memset(). Fixes: 4b1b7d3b ("net/smc: add SMC-D diag support") Suggested-by:
