* Remove the concept of process ownerSergey Bugaev2022-08-101-0/+1
| | | | | | | | | | Now that it's completely unused. procinfo.owner is now simply set to the first UID that a process has. proc_setowner () is kept for compatibility, but now does nothing. The clients still try to call it, though, for compatibility with older proc server versions.

* login: More port leaks fixesSamuel Thibault2022-01-041-2/+9
| | | | | | ports[INIT_PORT_CRDIR] and [INIT_PORT_CWDIR] were obtained from getcrdir() and getcwdir(), so a referenced needs to be released when replacing them.
* Fix leaking auth portsSamuel Thibault2022-01-041-4/+24
| | | | | | | | | | | We need to be extremely careful with auth ports since leaking them into subprocesses may expose a root-auth port to non-root processes. Notably, get_nonsugid_ids was caching it, thus preventing glibc's exec implementation from dropping it. Login is also reimplementing hurdexec but without all the cloexec logic. This commit fixes various auth leaks.
