Anant Thazhemadam 229bdf0b13 net: 9p: initialize sun_server.sun_path to have addr's value only when addr is valid ... [ Upstream commit 7ca1db21ef ] In p9_fd_create_unix, checking is performed to see if the addr (passed as an argument) is NULL or not. However, no check is performed to see if addr is a valid address, i.e., it doesn't entirely consist of only 0's. The initialization of sun_server.sun_path to be equal to this faulty addr value leads to an uninitialized variable, as detected by KMSAN. Checking for this (faulty addr) and returning a negative error number appropriately, resolves this issue.
