41 ** CONF.C -- Sendmail Configuration Tables.
43 ** Defines the configuration of this installation.
45 ** Configuration Variables:
46 ** HdrInfo -- a table describing well-known header fields.
47 ** Each entry has the field name and some flags,
48 ** which are described in sendmail.h.
51 ** I have tried to put almost all the reasonable
52 ** configuration information into the configuration
53 ** file read at runtime. My intent is that anything
54 ** here is a function of the version of UNIX you
55 ** are running, or is really static -- for example
56 ** the headers are a superset of widely used
57 ** protocols. If you find yourself playing with
58 ** this file too much, you may be making a mistake!
64 ** Final (null) entry contains the flags used for any other field.
66 ** Not all of these are actually handled specially by sendmail
67 ** at this time. They are included as placeholders, to let
68 ** you know that "someday" I intend to have sendmail do
69 ** something with them.

3571 ** Unfortunately, given that we can't predict other systems on which
3572 ** a remote mounted (NFS) filesystem will be mounted, the answer is
3573 ** almost always that this is unsafe.
3575 ** Note also that many operating systems have non-compliant
3576 ** implementations of the _POSIX_CHOWN_RESTRICTED variable and the
3577 ** fpathconf() routine. According to IEEE 1003.1-1990, if
3578 ** _POSIX_CHOWN_RESTRICTED is defined and not equal to -1, then
3579 ** no non-root process can give away the file. However, vendors
3580 ** don't take NFS into account, so a comfortable value of
3581 ** _POSIX_CHOWN_RESTRICTED tells us nothing.
3583 ** Also, some systems (e.g., IRIX 6.2) return 1 from fpathconf()
3584 ** even on files where chown is not restricted. Many systems get
3585 ** this wrong on NFS-based filesystems (that is, they say that chown
3586 ** is restricted [safe] on NFS filesystems where it may not be, since
3587 ** other systems can access the same filesystem and do file giveaway;
3588 ** only the NFS server knows for sure!) Hence, it is important to
3589 ** get the value of SAFENFSPATHCONF correct -- it should be defined
3590 ** _only_ after testing (see test/t_pathconf.c) a system on an unsafe
3591 ** NFS-based filesystem to ensure that you can get meaningful results.
3592 ** If in doubt, assume unsafe!
3594 ** You may also need to tweak IS_SAFE_CHOWN -- it should be a
3595 ** condition indicating whether the return from pathconf indicates
3596 ** that chown is safe (typically either > 0 or >= 0 -- there isn't
3597 ** even any agreement about whether a zero return means that a file
3598 ** is or is not safe). It defaults to "> 0".
3600 ** If the parent directory is safe (writable only by owner back
3601 ** to the root) then we can relax slightly and trust fpathconf
3602 ** in more circumstances. This is really a crock -- if this is an
3603 ** NFS mounted filesystem then we really know nothing about the
3604 ** underlying implementation. However, most systems pessimize and
3605 ** return an error (EINVAL or EOPNOTSUPP) on NFS filesystems, which
3606 ** we interpret as unsafe, as we should. Thus, this heuristic gets
3607 ** us into a possible problem only on systems that have a broken
3608 ** pathconf implementation and which are also poorly configured
3609 ** (have :include: files in group- or world-writable directories).
