Prepend "_diskfs" to uses of NOSUID & NOEXEC.
|
|
* priv.h (nosuid, noexec): New variables.
* init-init.c (nosuid, noexec): New variables, initialized to zero.
* file-exec.c (diskfs_S_file_exec): If noexec is on, then prohibit
all execution with EACCES. If nosuid is on, then prohibit setuid
or setgid execution by silently omitting the uid substitution.
* opts-std-startup.c (parse_startup_opt): Implement --no-suid and
--no-exec.
* opts-common.c (diskfs_common_options): Add --no-suid and
--no-exec.
* opts-std-runtime.c (struct parse_hook): Add nosuid and noexec.
(parse_opt) [cases 'S', 'E', OPT_SUID_OK, OPT_EXEC_OK] Understand
--no-suid, --no-exec, --suid-ok, and --exec-ok.
(parse_opt) [case ARGP_KEY_INIT]: Initialize H->nosuid and
H->noexec.
(OPT_SUID_OK, OPT_EXEC_OK): New macros.
(std_runtime_options): Add --suid-ok and --exec-ok.
(set_opts): Set nosuid and noexec from H->nosuid and H->noexec.
* opts-common.c (diskfs_common_options): Rename --nosync to
--no-sync; leave --nosync as an alias.

* file-exec.c: Include <fcntl.h> instead of <fcntlbits.h>.
Suggested by Marcus G. Daniels (marcus@cathcart.sysc.pdx.edu).

* diskfs.h (diskfs_hard_readonly): New variable.
(diskfs_readonly): Doc change.
* readonly.c (diskfs_readonly): Provide initialized declaration.
(diskfs_check_readonly): If we cannot write the media and so we
switch to readonly, set diskfs_hard_readonly too.
(diskfs_set_readonly): If diskfs_hard_readonly is set, then
inhibit any attempt to clear readonly status.

Pass a prototype peropen instead of the dotdotport and depth to
diskfs_make_peropen.
|
|
Supply DEPTH argument to diskfs_make_peropen.

Unlock NP before we attempt to do setuid/setgid (which otherwise can
deadlock during port reauth).
Pay attention to the error code returned by fshelp_exec_reauth, and don't
make NEWPI if it's an error.
Initialize ERR.
|
|
diskfs_make_protid, and deal with an error return.
|
|
(setid, scan_ids): Functions deleted.
|
|
Always reauth the proc port, as exec does not do it, even in the secure
case. Set the proc's owner too.
|
|
Don't touch the return params unless we succeed.
Add SETID parameter, and just copy old into new unless it's set.
Handle the NOLDGENIDS == 0 case correctly.
(diskfs_S_file_exec):
Use the new setid() properly.
Make sure that {GEN,AUX}{UIDS,GIDS} are always in a state where they can be
freed.
|
|
(scan_ids): Moved out of diskfs_S_file_exec.
(diskfs_S_file_exec):
Move duplicated code into setid().
Make the bogus auth port case work correctly.
Deleted old ifdefed-out code.
Enable setuid code.
|
|
port; just deallocate it.
|
|
directory. Dike out totally bogus set[ug]id code. Bother to lock NP
around critical section.
|
|
diskfs_make_protid.

|
|
to MACH_MSG_TYPE_COPY_SEND.
|
|
because it consumes a reference, which will be consumed again by
mach_msg_server if we return an error. So use COPY_SEND instead, and
deallocate the rights ourselves only when we are to return success.
|
|

|
|
here. (Later, we should also deal if exec_exec returns that the
previous server died.)
