- {
- /* AIX 3 stuff - inspired by a code fragment in wu-ftpd */
- /* MWW: This is all undocumented, of course. There's a patch to WU-ftpd
- in the AIX FAQ which does the setpriv, then sets the gid stuff, then
- sets uid. Since Samba separates setting the gid and setting the uid,
- I've duplicated the setpriv code in become_gid. I've also made the
- requisite changes to become_gid to match the WU-ftpd patch.
-
- I believe we'll still get errors in the Samba logs. This setpriv
- call is supposed to disable "trapdooring" on AIX - ie. normally
- once a seteuid / setegid is done, the effective ID can't be set back
- to what it was before. See the comments in become_root / unbecome_root.
- I *think* that we may have to do something additional here to prevent
- the "Can't set uid (AIX3)" messages, though - possibly change the
- values of priv.pv_priv to keep the SET_PROC_DAC privilege, and
- possibly SET_OBJ_DAC and SET_OBJ_STAT as well.
-
- The pv_priv array is two longwords, and the constants in sys/priv.h
- have values between 1 and 64, according to the comments in priv.h.
- This strongly suggests a bit vector - but does BYPASS_DAC_WRITE
- (#define'd to 1) mean 1<<0 or 1<<1? Unfortunately, nothing's
- defined to 0 or 64, which would be a dead giveaway. Also, what's the
- fullword-boundary endianness? That is, is pv_priv[0] the high or
- the low 32 bits? Fortunately, the values used by "su" (see below)
- don't make much sense if pv_priv[0] is the high bits. Also, based
- on analysis of the values used by su, I concluded that, for example,
- BYPASS_DAC_READ (defined to 2) is bit "2" counting from 1 - ie.
- if (pv_priv[0] & (1 << (BYPASS_DAC_READ - 1))) then BYPASS_DAC_READ
- is on. That's a bit odd, but it makes more sense than if the
- privilege constants are meant to be taken as exponents of 2.
-
- For analysis, I ran "su" as root under dbx, and stopped in setpriv.
- The first argument to setpriv can be examined using
-
- print $r3 (eg. "0x30009" = PRIV_SET|PRIV_MAXIMUM|PRIV_EFFECTIV)
-
- the contents of the pv_priv array can be examined using
-
- ($r4)/2X
-
- Here's what su does:
-
- setpriv(PRIV_SET | PRIV_INHERITED | PRIV_BEQUEATH, {0,0})
- setpriv(PRIV_SET | PRIV_EFFECTIVE | PRIV_MAXIMUM,
- {0x02800006, 0x00040000})
- 0x02800006 = SET_PROC_AUDIT | SET_PROC_ENV |
- BYPASS_DAC_EXEC | BYPASS_DAC_READ
- 0x00040000 = TPATH_CONFIG
- setpriv(PRIV_SET | PRIV_EFFECTIVE, {0, 0})
-
- Analysis:
-
- Reduce inherited privileges to none, so the child doesn't inherit
- anything special.
- Change su's privileges so it can execute the shell even if someone
- has goofed up the permissions to it or to directories on the
- search path; so it can set the process auditing characteristics
- and privileged environment (stuff in /etc/security/environ with
- the sysenv attribute); and so that it can set the trusted path
- characteristics for this login.
- Zap those privileges back off when we don't need them any more.
-
- I'm guessing we want to keep SET_PROC_DAC in the current priv set,
- but not in the inherited one. That is, set PRIV_INHERITED and
- PRIV_BEQUEATH to 0. We also probably want to set PRIV_MAXIMUM and
- PRIV_EFFECTIVE to only the privs we need, which at this point would
- appear to be just SET_PROC_DAC. *Note*: setting PRIV_MAXIMUM
- with any of the privilege sets higher than what you're trying to
- set the maximum to will produce an EINVAL. For example, if we
- try to set PRIV_MAXIMUM to SET_PROC_DAC *before* we reduce
- PRIV_INHERITED and PRIV_BEQUEATH, it won't work. Zero out the
- inherited privileges first.
-
- Some experimentation with simple programs confirms that if we're
- running with an EUID of 0 we can switch our UID/EUID back and
- forth with setuidx - *unless* we call setpriv({0,0}, ...) first.
- In other words, by default root has SET_PROC_DAT set, but we can
- remove it from our privilege set. This is what we want to do for
- child processes, I believe.
-
- Also, calling setpriv(PRIV_SUB|PRIV_EFFECTIVE,...) with pv_priv[0]
- set to SET_PROC_DAC (1 << (SET_PROC_DAC - 1)) will prevent an
- EUID-root process from switching its EUID back with setuidx.
-
- In other words, setuidx on AIX is *not* trapdoor. setuid is
- trapdoor. We need a non-trapdoor setuid function, but we don't
- want processes we fork to have access to it. Thus we use setuidx
- but first we disable it for our children.
-
- Note, however, that we can only increase our privileges (as we
- do in the first call to setpriv) if we're EUID-root. If we
- started out as root, and then switched to a non-root user ID,
- that's OK; we've already set them. Just don't try to set them
- again.
-
- Also, I suspect that after using setpriv / setuidx / etc. here in
- the AIX-specific code we DON'T want to fall through to the code that
- calls setuid, etc. However, I haven't noticed any more problems with
- the code the way it is here.
