[Differential] D9270: Add support for user-supplied Host-Uniq tag and handle PADM messages in Netgraph PPPoE
ale added a comment. Thanks for your comment, I'll improve the man page. INLINE COMMENTS > wblock wrote in ng_pppoe.4:108 > "host uniq" should be capitalized or otherwise identified with markup. Since > it's used below, just be consistent and say `Host-Uniq`. Are you fine with lower case "access concentrator"? > wblock wrote in ng_pppoe.4:109 > The formatting looks odd, but is apparently meant to show that there is an > optional AC-Name followed by double backslashes if present, followed by an > optional Host-Uniq with a vertical bar if present. Does this render > correctly? The double backslash is just for man page escaping, it's actually a single backslash. Both AC-Name and Host-Uniq are optional, that's the reason for different separators. > wblock wrote in ng_pppoe.4:118 > Markup could show these with out-of-band highlighting rather than quotes. > But I'm not sure which markup to use. I'll make a few tries, .Sq might be a good choice > wblock wrote in ng_pppoe.4:292 > "may" usually implies "you have permission", while "can" means "it is > possible". So: > > message with a HURL tag is received, and contains a URL which the Host can > > Should Host be capitalized? It's MAY in RFC 2119 meaning, but I'll change it to "can". I capitalized the Host to make it clearer what's the meaning of the H in HURL, but probably is not needed.

[Differential] D9270: Add support for user-supplied Host-Uniq tag and handle PADM messages in Netgraph PPPoE
ale retitled this revision from "Add support for user-supplied Host-Uniq tag in
Netgraph PPPoE" to "Add support for user-supplied Host-Uniq tag and handle PADM
messages in Netgraph PPPoE".
ale updated the summary for this revision.
ale updated the test plan for this revision.
ale added a subscriber: mav.
ale updated this revision to Diff 25849.
ale added a comment.
This revision now requires review to proceed.
- add client and server support for PADM messages, HURL and MOTM
- Fix a regression in PPPoE server introduced by previous patch version
- handle missing service name tag in PADI requests to cope with non fully
compliant client implementations, treat it as empty service name

[Differential] D9270: Add support for user-supplied Host-Uniq tag in Netgraph PPPoE
ale created this revision.
ale added reviewers: network, julian.
ale added subscribers: freebsd-net-list, mandree.
ale set the repository for this revision to rS FreeBSD src repository.
Herald added a subscriber: imp.
Herald added a reviewer: manpages.
REVISION SUMMARY
Add support for user-supplied Host-Uniq tag in Netgraph PPPoE.
A few ISP filter PADI requests based on such tag, to force the use of their
own routers.
The custom Host-Uniq tag is passed in the NGM_PPPOE_CONNECT control message,
so it can be used with FreeBSD ppp(8) without any other change.
TEST PLAN
I've tested the three possible Host-Uniq tags (auto-generated as before, long
plain string and long binary string) with my own ISP connection.
