freebsd 4.7-stable kernel gre tunnel support for squid's wccp cisco interaction
Hello, I upgraded /usr/src from 4.7-RELEASE to 4.7-STABLE by cvs and trying to compile it for transparent web-caching with squid (wccp support). I tried the steps described in http://www.squid-cache.org/Doc/FAQ/FAQ-17.html as i did before. I knew from older experiences that the gre.patch given here was wrong in last part (cause of removed "__P(...)" stuffs in the file ip_var.h) so you had to do the changes manually. However, by the date 20-Nov-2002, new patch released at http://www.squid-cache.org/WCCP-support/FreeBSD-4.x/4.7-gre.patch . Unfortunately, even this patch's last part designed for 4.7 - ip_var.h format, again fails for 4.7-STABLE, so you have to do the last part manually again (line 185 at /usr/src/sys/netinet/ip_var.h changed from "void ipip_input(struct mbuf *, int, int);" to "extern void (*ipip_input)(struct mbuf *, int, int);" ). Real problems starts here. Firstly, when you do the gre patches for wccp support, and try the compile the kernel with "option GRE", following error appears: In file included from /usr/src/sys/net/if_gre.c:77: /usr/src/sys/netinet/ip_var.h:184: conflicting types for `gre_input' /usr/src/sys/netinet/ip_gre.h:41: previous declaration of `gre_input' /usr/src/sys/netinet/ip_var.h:184: warning: redundant redeclaration of `gre_input' in same scope /usr/src/sys/netinet/ip_gre.h:41: warning: previous declaration of `gre_input' /usr/src/sys/net/if_gre.c:120: warning: initialization from incompatible pointer type /usr/src/sys/net/if_gre.c:120: warning: initialization from incompatible pointer type /usr/src/sys/net/if_gre.c:127: warning: initialization from incompatible pointer type /usr/src/sys/net/if_gre.c:127: warning: initialization from incompatible pointer type *** Error code 1 Stop in /usr/obj/usr/src/sys/BIGMETUCACHE. *** Error code 1 Stop in /usr/src. *** Error code 1 Stop in /usr/src. I realized the file /usr/src/sys/netinet/ip_gre.h with the line "void gre_input(struct mbuf *, ...);" but the patch defined it as "void gre_input(struct mbuf *, int, int);" ip ip_var.h file. The file is changed at 1.Dec.2002 . I tried some other things but didn't work. How can i enable wccp support on FreeBSD-4.7-STABLE updated today? I would appreciate any suggestions.

I tried some combinations, but unable to success the WCCP communication on GRE tunnel. However, Henrik, from squid-cache.org, warn me about there may not be WCCP support to an existing GRE module.

freebsd 4.7-stable kernel gre support for squid's wccp cisco interaction
Hi all, I need any suggestions about GRE support of 4.7 stable series of FreeBSD, because of the fact that squid's WCCP communication to Cisco devices over GRE is NOT working. At squid side, a patch for FreeBSD is available, but after the incorporation of GRE into STABLE on 1st December, it's not applicable. On the other hand, creating GRE interface, tunneling between Cisco device and BSD box, is not working for WCCP. Henrik Nordstrom from squid-cache.org, warn me about WCCP/GRE encapsulation may not be included in FreeBSD STABLE. Is it possible to add WCCP support on existing GRE module?

Re: pseudo-device gre and wccp/squid
Actually, since "A gre(4) driver, which can encapsulate IP packets using GRE (RFC 1701) or minimal IP encapsulation for Mobile IP (RFC 2004), has been added", WCCP over GRE has not been working on FreeBSD Stable systems, because there is no WCCP support in new GRE driver. I tried the same things as you did. I e-mailed this situation several times to lists since 12/11/2002, but there is no action. Henrik Nordstom from squid-cache.org, said that adding WCCP support to an existing GRE module is in most cases trivial as the packet format is identical to plain IP over GRE except for the protocol type, and that GRE is only used in one direction (Router -> Proxy) not as a bidirectional tunnel.

Everything worked fine before the upgrade, but I was using the gre patch from squid's web site to do the work. The new pseudo-device appears to have WCCP-specific code in it, but it's not working. Does anyone have this working? Anyone at all? I'm willing to break down and switch to ipfw if that'll help, but I can't upgrade my machines to 4.7 (and higher) properly without a fix. Surely someone has used this since the code was commited. (A hack would be to comment out all code related to the pseudo-device so I can use the wccp-specific gre.c.) Faried.
