...http://tcng.sourceforge.net/#src This one has the first steps towards getting non-IPv4 classification right: - I''ve added fields for skb meta-data (meta_protocol, etc.) - if USE_META_PROTOCOL is #defined (tcc -D... or tcsim -Xc,-D...), ip_hdr and ip6_hdr check the protocol number - if_u32 generates distinct classifier branches for each protocol - f_fw, f_tcindex, and f_u32 now default to ETH_P_ALL instead of ETH_P_IP The latter change affects how u32 classification works ! tests/protu32 illustrates how protocol-aware classification is used. What''s missing: - C and t...

... is on SourceForge, http://tcng.sourceforge.net/#src This one fixes a really stupid typo causing tcsim''s tc to pick up HZ from the environment where it''s being run, not the simulation environment, which confused most rate calculations. And if_u32.c now only emits hashes that will actually be used, which should make tcc''s tc output a little less ugly.

...or shaping, upon learning of tcng, I redid my config, and load it using tcc. I thought this was great, as the new script is much easier to maintain, and is so much simpler. The new script was working for about a week, then it stopped working. I now get this error: can''t dump subexpression (if_u32.c, unsupported offset sequence - please try to reorder matches) [&&]--[offset]--[==]--[&]--[access]-- (none) | | | | +-------- 0 | | | | `-------- 16 | | | `--- 65535 | | `---- 22 | `--------[<<]--[&]-...

...mtc work smoothly: - tcc''s -E option is now called -Wexperror or -Wexppostopt, respectively - tcc has a _new_ -E option that makes it behave much like gcc -E - tcc also has a new option -f that is used to override the input file Some of the bug fixes are also significant: - if_u32.c sometimes generated incorrect classifiers when using meta fields (disabled by default) - tcc and tcsim happily copied all file name arguments to cpp, which would then equally happily overwrite the second file Also, tcsim''s "end" command now checks if there are any polle...

...ts/minisrc.sh now also recognize the Debian iproute tarball - tcsim/setup.klib: added "time_after" and "time_after_eq" to linux/sched.h - tcsim/setup.klib: converts dsfield.h to remove bare newlines from strings (needed to build tcsim with old kernel sources and a new gcc) - if_u32.c:dump_and now checks if any but the last && term changes the offset group (tests/tcng-9m; updated tests/tcng-2i, reported by Laurent Moutel) - tcsim/Makefile: compile tcsim.c without kernel includes, to avoid confusing glibc headers (reported by Nuutti Kotivuori) -- _______________...
