I'm not saying this is a very good policy, no!

Postfix does not require that many lines there! C'mon! But I don't know better yet, and it seems to work fine:

A tip for postfix:

Since all of the accesses are mostly alike between the various subjects for it, it's simpler to create a subject for the directory all the binaries are located in: /usr/libexec/postfix and then perform per-subject learning on that. Then you'll only have one subject to maintain instead of a dozen or so.

Thank you most kindly for the reply. I had already in the meantime figured it in part, and applied it somewhat correctly I think. Of course, not completely sure..,

I'm currently having trouble with postfix, but that may be because something in the

Code: Select all: # uname -r 4.0.7-hardened-150705 #

kernel (there were issues at the release of 4 kernel, I read somewhere).

(The postix issues with kernel 4 are unrelated to grsecurity, I believe.)

And the following is a digression not about postfix (to which I'd like to return, but at an undefined later time), but is on generally grsec.

It is taking me time, real time, anyway... I always hope to be able to transfer my knowledge (I am slowly getting in ever better terms with gradm), like I manage to do on the Debian Tip I made:

Grsecurity/Pax installation on Debian GNU/Linux
http://forums.debian.net/viewtopic.php? ... 6&p=516898

which is a testimony (currently 35215 Views) not really of my cleverness (I do not presume that really, sometimes quite the contrary is how I feel), but of the need for it...

Of the need for slow detailed, complete, and really for-beginners explanation on matters grsecurity.

But gradm is so much broader, so much more work, and I don't know when I will hopefully be able to transfer my understanding of how to use it

(
of course, widening the:

Grsecurity
https://en.wikibooks.org/wiki/Grsecurity

with examples for real beginners on some fori like either Debian Forums (but I really really can't stand systemd, their default) or on Devuan Forums if (as a lot of us hope, the Devuan takes off for real, or even on Gentoo Forums), but I know I am really not yet there
).

I love grsecurity the most in all of Fossdom.

Thank you spender, and thank you PaX Team!

P.S. I decided that this posted on a future talk on how to gradm-learn and deploy grsecurity protection on Postfix, another paramount program of our times, that this really is (as I write there) an afterthought, and a promise, and posted a link to here in that Tip:

To be honest, I'm reluctunt to post the complete real /etc/grsec/policy here.

Exactly for the reason that I would discover my defences if I did that now that it has changed a lot since I posted it in the top post of this topic, exactly for that reason, I did it then, and won't reveal my complete, improved /etc/grsec/policy now.

But I've given the Dillo RBAC deployment over in this topic:

Deploy RBAC on Dillo browser
viewtopic.php?f=5&t=4153#p15003

And I'll give here real RBAC lines on all of my Postfix installation. You can see there are so much fewer subjects now.

LATER CORRECTION START (two times edited): I thoght that I reduced my Postfix entries in /etc/grsec/policy
But I remember now, I had to go back, because it partly wouldn't work. This is still considerably shorter than I had before, as I took time to look into it more carefully.

You can see the entry starting with:

Code: Select all: subject /usr/libexec/postfix o {

But I seem to have not completely succeeded in applying spender's advice, as I had to bring back in some of the specific subjects on binaries in that /usr/libexec/postfix directory, as I recollect, it wouldn't work otherwise.

I'm still pouring over how to achieve the simple setup that spender directed countermode how to di, with postfix:

Well, there's probably still some bloat in there, but not so much...

It makes some less then 10% of the entire policy:

Code: Select all: # ls -l /etc/grsec/policy grsec_150707_POSTFIX -rw------- 1 root root 109905 2015-07-07 10:47 /etc/grsec/policy -rw-r--r-- 1 root root 10842 2015-07-07 19:45 grsec_150707_POSTFIX-this-configuration #

I hope this helps others, and if any more advanced users have any advice in regard, I will be grateful!

OTOH, I might yet need to return here, as I have occasional issues with my current installation of Postfix, as I described in:

Postfix not working (title to change, incorrect)
https://forums.gentoo.org/viewtopic-t-1021456.html

by **timbgo** » Thu Jul 09, 2015 12:31 am

Maybe a few words of explanation, directed for the less advanced users than me (as the interest for the basically finished topic:

Grsecurity/Pax installation on Debian GNU/Linux
http://forums.debian.net/viewtopic.php? ... 6&p=516898

demonstrates that newbies want the freedom that Grsecurity can greatly help them achieve).

I'll try and explain what is specific for my machine's setup, with the current e-mail addresses that I use, so you can extract those when you try and apply some of the understanding you gain by reading this topic, on top of most surely:

Grsecurity on Wikibooks
https://en.wikibooks.org/wiki/Grsecurity

as that is where you need to spend serious time first)

The lines, which are there in a few places in my postfix RBAC policy code:

Code: Select all: connect 127.0.0.1/32 ip dgram stream tcp udp connect 195.29.150.0/24 ip dgram stream tcp udp connect 178.218.164.164/32 ip dgram stream tcp udp

I skip the first for now (the 127.0.0.1/32 ... line).

The 195.29.150.0/24 address in the second line, makes for any addresses in the last octet of the four of that IPv4 address, to be allowed, that is all addresses from 195.29.150.1 ... 195.29.150.255. Those are addresses of my really obnoxious provider, the Croatian T-com, so I can use the address they gave me: miroslav.rovis1@zg.ht.hr (see the '1' in the name? No it's not that my clean name was occupied by someone else, it's just that they like to hurt people, namely that is the only address that I have at that ISP, and they get all my moneys every month, it's not a free email).

So, for your setup, you need to know which address your (provider's) mail servers are at. People using postfix for having their own server for their own domain hosted at their own computors... They basically don't need my advice, they are more advanced. I write this with mostly the newbies in mind that need postfix, because Postfix is also really great for having an honest and perfect Mail Transfer Agent dealing with your provider's mail servers, so you can stay in control. Have a look at the role Postfix played in my difficult issues with my providers previous and current:

Postfix smtp/TLS, Bkp/Cloning Mthd, Censorship/Intrusion
https://forums.gentoo.org/viewtopic-t-999436.html

And the third line, the line with 178.218.164.164/32 allows only that address, 32 masks all the four octets of that IPv4 address. That is the (current) hoster of my http://www.CroatiaFidelis.hr domain, and also of the mail server for my miro.rovis@croatiafidelis.hr email-address.

---

That's some explanation. I'm having some occasional issues like:

Code: Select all: Jul 7 16:57:28 g0n postfix/tlsmgr[29122]: dict_open: btree:/var/lib/postfix/smtp_scache Jul 7 16:57:28 g0n postfix/tlsmgr[29122]: fatal: set_eugid: seteuid(0): Operation not permitted Jul 7 16:57:28 g0n kernel: grsec: (root:U:/usr/libexec/postfix) change to uid 0 denied for /usr/libexec/postfix/tlsmgr[tlsmgr:29122] uid/euid:0/207 gid/egid:0/207, parent /usr/libexec/postfix/master[master:4035] uid/euid:0/0 gid/egid:0/0 Jul 7 16:57:29 g0n postfix/master[4035]: warning: process /usr/libexec/postfix/tlsmgr pid 29122 exit status 1 Jul 7 16:57:29 g0n postfix/master[4035]: warning: /usr/libexec/postfix/tlsmgr: bad command startup -- throttling

and also I'll be having some serious mind work in reconfiguring my Postfix again, because the Plus.hr provider, which currently host CroatiaFidelis.hr and the mail for it, I think have switch from stunnel wrappermode TLS to standard TLS, as I explain in:

Postfix not working (to be retitled)
https://forums.gentoo.org/viewtopic-t-1021456.html

and I don't know what I will end up with, but will post my Postfix RBAC policy that I will eventually settle for (that may take an undefined time, for shorter or for longer).

Looking at my current RBAC policy for Postfix:

( this same topic )
viewtopic.php?f=5&t=4153#p15354

I think I still need to do more learning on the (notice the Role: postfix):

Code: Select all: # Role: postfix subject /usr/libexec/postfix ol { / hide -CAPS_ALL bind disabled connect disabled }

followed by the usual:

Code: Select all: gradm -C

when I'll be told of the holes, but only because I have enabled the ... ol ... learning mode, and:

Code: Select all: gradm -L /etc/grsec/learning.logs -E

and after done all the usual to be operations with postfix, then:

Code: Select all: gradm -D

and finally:

Code: Select all: gradm -L /etc/grsec/learning.logs -O /etc/grsec/policy

The same too many subjects as before, are still there, because I had done the learning those few months ago or longer, but only for (notice the Role: root):

Code: Select all: # Role: root subject /usr/libexec/postfix ... ...

(and not yet, but I now plan to, on the Role: postfix).

The two different sets for same subjects, one in the role root, and one in the role postfix, were created by first long learning (a few days, because it takes me longer to remember all that I usually, or more rarely, do) for the very first /etc/grsec/policy, which you have further above.

I don't know why two sets of same subjects, one for role root and one for role postfix, for those various postfix subjects, but it was set by grsecurity after the learning, and I kept it.

More work pending on this issue, at an undefined time in the future.

It's not very easy for me to post my policy, but grsecurity has defended me so marvelously and gave a substantial leap in my computing-related life, that I just enjoy revealing some more of it. Not for being certain that I do create all of my policy the right way, far from! I fear there are weaknesses and will be thankful to anybody who points to the bad arrangements or worse in my policy!... But it's good for newbies to have examples of policies.

It's true that lots of it I changed in the old policy above in the meantime (I change my policy, on average, on a weekly basis), and I'm not that confident I can post the complete current policy of mine without running some risk...

But I'm happy and can teach a little just why and how some changes are done, as I solve some important difficulty for me at the start of an important tutorial, and so...

And sohis is an reference necessary for my article:
