* libfshelp: Port to x86_64Sergey Bugaev2023-05-101-8/+12

* Rename proc_complete_reauthentication to proc_reauthenticate_completeSamuel Thibault2022-08-101-1/+1
| | | | For coherency with the existing RPCs
* Make proc_reauthenticate () recreate proc portSergey Bugaev2022-08-101-3/+13
| | | | And add proc_complete_reauthentication ()
* Remove the concept of process ownerSergey Bugaev2022-08-101-3/+9
| | | | | | | | | | 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.
* libfshelp: Handle proc port in fshelp_start_translator_long ()Sergey Bugaev2022-08-101-7/+49
| | | | | | | | | | | | | | While fshelp_start_translator_long () has been calling proc_setowner () on the task it creates, it has never reauthenticated its process. This meant that the translator, once started, could access processes authenticated same as the process that called fshelp_start_translator_long (). In particular, this means that any unprivileged translator started by a privileged parent translator had in fact had a privileged proc port, and could access other processes through it. With this change, fshelp_start_translator_long () will now reauthenticate the process it creates. Moreover, it will now respect a custom proc server port passed in the given ports.

* libfshelp: Simplify fshelp_start_translator_long () a bitSergey Bugaev2022-08-101-39/+14
| | | | | | | It only really supports ports_len > INIT_PORT_BOOTSTRAP, ports_type == MACH_MSG_TYPE_COPY_SEND, fds_type == MACH_MSG_TYPE_COPY_SEND. Make that explicit, and remove the branches that tried to handle the other cases.

* libfshelp: improve error handling in fshelp_start_translator_longJustus Winter2013-11-281-5/+6
| | | | | | | | Properly deallocate all ports and terminate the started translator if an error occurs. * libfshelp/start-translator-long.c (fshelp_start_translator_long): Improve error handling.
* Reset task priority when spawning a passive translatorRichard Braun2013-05-311-0/+8
| | | | | | | | | | | Server threads spawned by libports attempt to adjust their priority and succeed when the server is privileged. This priority is currently inherited by child tasks, which could be passive translators owned by unprivileged users. Reset the priority of the task used for translator instantiation. * libfshelp/start-translator-long.c (fshelp_start_translator_long): Set new task priority to 25 (BASEPRI_USER).

| | | | | | Add values for the dealloc parameters to file_exec (all false). Give away our send right to TASK when we do file_exec. Initialize BOOTSTRAP & TASK so the cleanup code doesn't get confused.
