* proc: Fix pointer truncation in get_string_arraySergey Bugaev2023-06-211-2/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Due to little-endianness of x86, this resulted in a 64-bit pointers that pointed to the lower 4 GB of the address space being treated as a 32-bit pointer followed by NULL, which manifested as only the first program arg (the argv[0]) being visible in ps output. When a pointer pointed outside of the lower 4 GB, this resulted in both halves being treated as invalid pointers, causing proc_getprocargs () to fail with KERN_INVALID_ADDRESS, which manifested as ps displaying COMMAND for the affected process as ?. Found by placing all memory above the 4 GB limit, which made it apparent that something about fetching process command lines is seriously broken.

* Remove the concept of process ownerSergey Bugaev2022-08-101-2/+5
| | | | | | | | | | 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.
* proc: Use UIDs for evaluating permissionsSergey Bugaev2022-08-101-9/+31
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The previous scheme was to check that PROC1 has the UID that is designated as PROC2's "owner". This is extremely problematic for several reasons, including: * The UIDs and the owner of a process are set separately and can easily get out of sync. While S_proc_setowner () checks that the new owner is among the UIDs that the process has, this invariant is violated after the process is given a new set of UIDs with S_proc_reauthenticate (). In particular, this happens during execution of a SUID binary: the process is reauthenticated to a different set of UIDs first, and its owner is udpated later, if at all. * In the Hurd, a process can have multiple UIDs. Having to designate just one of them as the owner means the other UIDs get ignored for the purpose of permission checking. One particularly problematic case is a SUID process that temporarily lowers its effective UID: glibc sets the first effective UID as the process owner, giving just about anyone access to the task. Resolve this by ignoring the owner for the purpose of permission checking, and relying solely on the authenticated UIDs. Roughly speaking, PROC1 can get complete access to PROC2 if the UIDs PROC1 has form a superset of the UIDs that PROC2 has; in other words, the access is only allowed when it would not result in PROC1 getting access to UIDs it doesn't have already. Of course, root is still allowed to access any process. In particular, this means that: * a process can access another process if they have the same auth; * a process that has "more auth" can access one that has "less auth", but not the other way around; * a SUID-root process that has lowered its effective UIDs can only be accessed by root. Another important point here is that the UIDs in question are both effective and available UIDs that a process has. Normally, available UIDs are ignored for the purpose of permission checking (and that is their whole point). However, POSIX description of kill(2) has the following clause: > For a process to have permission to send a signal to a process designated by > pid, unless the sending process has appropriate privileges, the real or > effective user ID of the sending process shall match the real or saved > set-user-ID of the receiving process. Which I read as saying that the real (i.e. available) UID(s) of PROC1 should be used for evaluating whether kill(2) can succeed, not only its effective UID(s).

* hurd: Use polymorphic port types to return some rights.Justus Winter2017-03-101-2/+6
| | | | | | | | | | | | | | | | | | | | | Currently, the RPC definitions of two procedures of the process subsystem assume that the rights are created from a receive right. Similarly, 'proc_getmsgport' assumes that the right is to be copied. This needlessly limits the ability to relay the RPC in server code. This fixes this. The protocol is unchanged, only the generated server stubs assume an additional parameter for the type. * hurd/process.defs (proc_getmsgport): Make 'msgport' parameter polymorphic.
