christos 4fb8bf7262 PR/4098: Alan Barrett: Fix diagnostic printf formatting. 1997-09-10 13:44:20 +00:00
thorpej a79a3ca472 Fix a reversed argument which caused procfs_checkioperm() to always return
"OK".  Add a few comments to avoid further confusion.

explorer 945beb8d63 Move procfs_checkioperm() from procvs_subr.c to procfs_mem.c, since _subr is
not included in a kernel without procfs, and it seems wrong to pull
all of procfs_subr.c in for just that one function.  Perhaps this
should go into a new file instead?

thorpej f9777e4a1c Fix the procfs hole described on current-users, similar to a fix for
FreeBSD by Sean Eric Fagan, but a bit different.  This makes the checks
in the same places as sef's FreeBSD patch, but does not hardcode the
"kmem" group into the kernel, and also does a check identical to the
(3) and (4) checks in the NetBSD ptrace(2):

	(1) it's not owned by you, or is set-id on exec (unless
	    you're root), or

	(2) it's init, which controls the security level of the
	    entire system, and the system was not compiled with
	    permanently insecure mode turned on.

mycroft 2ee8bc2b79 Don't allow writes to init's memory or registers while in secure mode. 1997-06-25 11:32:15 +00:00
mycroft e3f99a9397 Pass the vnode type to vaccess(), and use it when checking VEXEC. Make sure
that the mode bits passed to vaccess() and returned by foo_getattr() contain
only permission bits.

appropriate.

mycroft 701f15db33 Reinstate P_FSTRACE, with different semantics:
* Never send a SIGCHLD to the parent if P_FSTRACE is set.
* Do not permit mixing ptrace(2) and procfs; only permit using the one that
  was attached.

mycroft 8a33a13c65 Minor code cleanup. 1997-04-28 03:49:57 +00:00
mycroft 217c4e14ea Fix several deficiencies, as compared to ptrace(2):
* Did not check for P_SUGID on ATTACH.
* Did not check for tracing of init on ATTACH.
* Did not turn off single-step mode on RUN or DETACH.
* Might have screwed up reparenting in some cases.
* Allowed anyone to detach the process.

cgd 90688fce27 Change the second and third args to struct vfsops' (*vfs_mount)() to
'const char *', and 'void *', respectively.  The second arg is taken directly
from user arguments, and is const there, so must be const in the prototypes
and functions.  The third arg is also taken directly from user arguments.
It doesn't have to be changed, but since it's cleaner to keep the type
the same as the user arg's type, and I'm already making the 'const char *'
change...

cgd a67c0b16b8 define path name string variables that we should not (and, thankfully, do
not) modify as 'const char *' rather 'char *'.
1996-10-25 21:57:58 +00:00
cgd eaa37ec87a remove bogus cast of second arg to bcmp(). (nm_name is a const char*,
and was being unnecessarily cast to 'char *'; -Wcast-qual.)

mycroft fce3e0874f Fix vop_link, vop_symlink, and vop_remove semantics in several ways:
* Change the argument names to vop_link so they actually make sense.
* Implement vop_link and vop_symlink for all file systems, so they do proper
  cleanup.
* Require the file system to decide whether or not linking and unlinking of
  directories is allowed, and disable it for all current file systems.
