tcng-10b (3-OCT-2004)

tcng-10b.tar.gz (507 kB) Changes: the "mtu" parameter in TBF is now optional tcsim now uses KVERSION[NUM] instead of KFULLVERSION[NUM] to avoid breaking if EXTRAVERSION contains multiple dots or other surprises (reported by Eduardo Grosclaude) scripts/runtests.sh now runs commands with LANG=C, to avoid localized error messages (reported by Eduardo Grosclaude)

tcng-10a (28-SEP-2004)

tcng-10a.tar.gz (507 kB) Changes: configure is compatible with 2.4.27 updated kernel version example in README from 2.4.26 to 2.4.27 scripts/compatibility.sh: added 2.4.27 changed name of "tcc" to "tcng", for collision with "tiny cc" (reported by Matthias Urlichs) scripts/localize.sh: now installs a wrapper for "tcng", pointing to "tcc" scripts/symlinks.sh: now adds a link from "tcng" to "tcc" tcsim/tcsim.c: now calls "tcc" as "tcng" configure: changed "tcc" to "tcng" at all user-visible places tcc/tcc.c: no longer identifies itself as "tcc" when invoked with -V Makefile: the binary distribution for "tcc" is now called "tcng" build/{tcng,tcsim}.spec.in: changed most references for "tcc" to "tcng" Makefile: removed lib/tcng/include/klib/kernel/include from TCSIM_BINDIST configure now uses include/SNAPSHOT.h instead of RELNOTES to detect iproute2 version configure is now compatible with iproute2-2.6.8-ss040730 and iproute2-2.6.9-ss040831 (updated tests/cbqroot and tests/tbf) tcng/README now recommends to download iproute2-2.6.9-ss040831.tar.gz (this also affects tcsim.spec) recent versions of iproute2 only support MPUs <= 255 bytes (updated tests/mpu) tcng can now use "conform-exceed" instead of "action" (updated tests/drop) configure: new options "--action" (or "-a") and "--conform-exceed" (or "-A") to override action handling tcc/Makefile now depends on ../config

tcng-9l.tar.gz (505 kB) Changes: configure did not preserve the YACC setting across sessions configure now complains if -k, -i, -d, -t, or -y have no argument tcc and tcsim now use -$ if -std=c99 does not work (updated tests/cppdollar) configure: new options "-$" and "--c99" (or "-c99") to override dollar handling the writer helper process of tcsim now always exits with _exit, to avoid running the exit handler that kills cpp runtests.sh converts " parse " to " syntax " in stderr if expecting an error, because some YACCs print "parse error" instead of "syntax error" examples/prio+fw, examples/tbf, examples-ng/pfifo_fast, examples-ng/prio+fw, examples/priority, tests/idiomatic, tests/packet, tests/tcsattpro, tests/tcsattpsv, tests/tcsattset, tests/tcsdefinc, tests/trace, tests/u32dlb, and tests/u32slb now avoid using variadic macros with an empty argument list all, to keep some versions of CPP from complaining tests/tcng-7g forced a syntax error at EOF, which yielded inconsistent results with different versions of CPP updated kernel version example in tcng/README from 2.4.22 to 2.4.25 q_htb.c: used ~0UL to mean "0xffffffffUL" moved removal of .depend from "clean" to "spotless" make target tcsim/Makefile: removed left-over dependencies on module cleanup targets "ephemeral-mod" and "clean-mod" tcsim/modules/Makefile did not define OBJS

tcng-9k (28-FEB-2004)

tcng-9k.tar.gz (504 kB) Changes: cpp 3.3.3 unceremoniously dropped "-$", so we're now using "-std=c99" (updated tests/cppdollar, tests/phasep; based on patch by Robin H. Johnson) tcc and tcsim now invoke cpp with argv[0] set to the name of cpp (instead of the name with which tcc or tcsim was invoked), for cpp 3.3.3 compatibility (updated tests/tcng-6u; fixed by Robin H. Johnson) POSIX obsoleted "tail -N", using "tail -n N" now (updated tests/tstcond; fixed by Robin H. Johnson) Makefile: added remark that the ebuild that comes with tcng isn't nearly as good as the one from Gentoo build system now uses bison if "configure" finds no yacc configure: added option --yacc (-y) to set the YACC command toys/comtc now uses extension .i instead of .cpp, since the latter caused cpp to switch to C++ mode configure: changed "dir_or_tarball" to "dir_or_tar.bz2" in description of "--kernel" argument configure now also accepts tarballs for iproute2 added scripts/minisrc.sh which extracts the files needed to build tcsim from an iproute2 tarball changed UNDEF_U32 from ~0UL to ~0U for 64 bit compatibility tcc/ext_io.c:expand_errors added casts to avoid complaints when using a pointer difference in printf on 64 bit setup.klib: elements of "struct timeval" are now "unsigned long" instead of "unsigned" for better compatibility with glibc on 64 bit kmod_cc and tcmod_cc now use -fPIC for amd64 compatibility tcc/ext/Makefile and tcc/ext/tcc-ext-test.in now use -fPIC for amd64 compatibility tcc/iflib_actdb.c:debug_subtree printed pointer to policier instead of its number setup.klib: linux/types.h now just #includes stddef.h instead of trying its own definitions for size_t and NULL changed long obsolete "make upload" to equal "make upload-sf"

tcng-9h (7-NOV-2003)

tcng-9h.tar.gz (497 kB) Changes: tcc/ext/Makefile: dependencies now only include .c files compiled in that directory, removing a warning when building RPMs split tcsim/Makefile into Makefile.unclean and Makefile.clean to avoid rebuilding klib and ulib when cleaning up after configuration changes configure is compatible with 2.4.22 and 2.4.23 (pre-release, tested with 2.4.23-pre9) setup.klib generates linux/smp.h needed for 2.4.22 tcsim/trace.c and tcsim/modules/sch_discard.c adjust ..._drop prototype for interface change in 2.4.22 setup.klib clears LANG before using sed on [^ -~] setup.klib adds "err" and "error_report" members to "struct sock" in af_netlink.c (for 2.4.23) updated kernel version example in tcng/README from 2.4.21 to 2.4.22 configure: added options --no-manual and --with-manual (abbreviations -m and -M) to allow building tcng with or without the documentation (suggested by "raptor") configure: automatically assumes --no-manual if either latex or dvips is not in the PATH

tcng-7y (12-MAR-2002)

tcng-7y.tar.gz (359 kB) Changes: added new qdisc "egress" that is synonymous to "dsmark", except that it implies "default_index 0", and that using it as an "inner" qdisc produces a warning (tests/egress) changed all error and warning messages mentioning "dsmark" to say "egress" if using egress (tests/egress) updated tests/extndm accordingly added regression test for dsmark's unnumbered and parameterless class warning (tests/dpcwng) fixed off by one error in dsmark index out of range diagnostic (tests/tcng-7y) updated tests/dsind and tests/tcng-1i accordingly ingress qdisc generated invalid default classification decision dt_class instead of dr_class (tests/tcng-7y)

tcng-6m.tar.gz (287 kB) Changes: scripts/runtests.sh now invokes tcc with -S -S -S, and tcsim with -Xc,-S -Xc,-S -Xc,-S -DTCNG_SEMICOLON converted examples-ng/* to new syntax converted tcc/example to new syntax converted toys/srtcm.tc and toys/trtcm.tc to new syntax de-crowded tests/arith, tests/host, tests/misfeatures, tests/named, tests/tcng-1i, tests/tcng-1j, tests/tcng-1o, tests/tcng-2f, and tests/tcng-3g converted all regression tests to new syntax removed ambiguous syntax tests from tests/misfeatures removed ugly old syntax tests from tests/newsynmsc and tests/semicolon tests/tcng-5y showed spectacular failure of old syntax, with subtle syntax ambiguity leading to subtle error in generated classifier TODO: removed entry for mythical __ file bug

tcng-6l (19-OCT-2001)

tcng-6l.tar.gz (287 kB) Changes: extra semicolons are now allowed where one semicolon or a block end appears, e.g. ;;; is equivalent to ; and }; is equivalent to } (tests/extrasemi) new syntax requires interface sections to be enclosed by curly braces (tests/newsynmsc) new syntax does no longer allow filters specified in selectors to have their own blocks (tests/newsynmsc) tcc now handles both old-style and new-style syntax for filters specified in selectors (tests/newsynmsc) updated tests/semicolon accordingly documented new syntax in tcc/LANGUAGE tcc.c:main did not allocated room for -DTCNG_*SEMICOLON in cpp argv, causing tcc to segfault if invoked without arguments empty tags are now ignored (updated tests/tcng-5a accordingly) empty pragmas are now ignored (updated tests/pragma accordingly) tags can now also be specified as "tag " (updated tests/tag) strings are now first-class data types in the tcng language, can be compared with relational operators, and can be concatenated with + (tests/string) updated tcc/LANGUAGE accordingly "host" can now be followed by an expression, not only a host name or IPv4 address (tests/named2) host, port, ipproto, and (ether) protocol parameters can now be also use strings expression, not just string literals or numeric expressions (tests/named2) variables now record the location where they are created, yielding much better location information in warnings updated tests/location, tests/selpath, tests/tcng-3k, tests/tcng-5c, tests/varredef, tests/waprpos, and tests/warn accordingly syntax changes changed the location indicated in some error messages. Updated tests/named accordingly tcc/LANGUAGE: split parameters section to cover expressions in their own section

tcng-6k (19-OCT-2001)

tcng-6k.tar.gz (283 kB) Changes: fixed precond() example in tcc/LANGUAGE (reported by Ronald Murphy) tcng language will soon require semicolons at the end of constructs, unless they end with a block, e.g. $x = 5 will be $x = 5; fifo will be fifo; but prio { ... } will stay the same tcc can help migration with the undocumented -S option: without -S, behaves like it did before, with -S it warns when using semicolons (for comments), with -S -S semicolons no longer begin comments, and tcc warns if a semicolon is missing somewhere, and with -S -S -S missing semicolons yield an error (tests/semicolon) updated fields.tc accordingly (remains backwards-compatible) tcc adds -DTCNG_NOSEMICOLON to CPP options if no or only one -S it set, -DTCNG_SEMICOLON if more than one -S is set meters.tc is now generated via macro-generating preprocessor scripts/var2fix.pl updated meters.tc such that it is generated to contain a part with, and one without semicolons (new files meters.tc.in and meters_nosemi.tc.in) duplicate global pragma location is reported more accurately updated tests/waprpos accordingly

tcng-6j (17-OCT-2001)

tcng-6j.tar.gz (281 kB) Changes: Makefile: "tcc" has no dependency on "symlink", breaking RPM build in 6i tcc/location.c:file_open printed wrong file name on error meters.tc: trTCM_red fell through if packet conformed to Tc, but not to Tp (tests/tcng-6j) if_ext_act.c:add_actions gave up too quickly when encountering unusual expressions (tests/tcng-6j)

tcng-6i (17-OCT-2001)

tcng-6i.tar.gz (281 kB) Changes: tcc and tcsim now print CPP's path if CPP isn't found (reported by Jacob) tcng-tests RPM no longer includes tests/usage, which can safely be tested in a regular build environment, and is very location-dependent fields.tc: renamed fields "ip", "tcp", etc. to "ip_hdr", "tcp_hdr", etc. updated tests/classvar, tests/field, tests/tcng-4n, and tests/tcng-5y accordingly described now consistent field naming convention in tcc/LANGUAGE tcm.tc now fails with an #error (was #warning) and will be removed very soon updated TODO

tcng-6h (15-OCT-2001)

tcng-6h.tar.gz (281 kB) Changes: unless -B is set: -N is now enabled by default, and double -N switches off -N (to reuse old regression tests for a while) updated tests/buckfill, tests/classvar, tests/expensive, tests/fastpath, tests/relop, tests/tcng-5j, tests/tcng-5y, and tests/tcng-5z accordingly build/tc{ng,sim}.spec.in: %doc came before %defattr, which caused documentation files to pick up wrong ownership meters.tc was not compatible with SuSE's CPP that identifies itself as CPP 2.95.2 but appears to be different from the CPP that comes with GCC 2.95.2

tcng-6g (15-OCT-2001)

tcng-6g.tar.gz (279 kB) Changes: tcc: moved generation of location map and variable use list before build phase, so external programs can use these files doc/external.tex: clarified that tokens need to be added to a bucket not only on "conform", but also on "count". removed corresponding (rather obscure) tests from tests/misfeatures tcc/ext/match.c and tcc/tcm_cls.c now refill buckets on "count" too (tests/buckfill) iflib_red.c:prune_shortcuts sometimes removed count in "count ... || 1" (tests/buckfill) tcm_cls.c now prints policer state if DEBUG is #defined added correct solution for double count test, and failure of "old" algorithm (tests/misfeatures)

tcng-6f (12-OCT-2001)

tcng-6f.tar.gz (279 kB) Changes: updated path to fields.tc in tcc/LANGUAGE added function "precond" that evaluates the preconditions of its argument (tests/precond) added regression tests for bit and other sub-byte fields (tests/subbyte) fixed subtle pointer aliasing issues in field.c

tcng-6e (12-OCT-2001)

tcng-6e.tar.gz (277 kB) Changes: updated kernel version example on tcng/README from 2.4.10 to 2.4.12 configure is now compatible with 2.4.12 and 2.4.13 (pre-release, tested with pre1) added #warning to tcm.tc, telling users to switch to meters.tc added test for count-count crash with -N -B to tests/misfeatures scripts/runtests.sh now searches PATH for executables build/Makefile: "variable" expansion sed scripts only expanded first occurrence of "variable" TCSIM_BINDIST and tcsim-devel now also contain header files from ulib/iproute2/include*, ulib/iproute2/tc/tc_{util,core}.h, toys/?rtcm.tc, and all examples tcc/ext/tcc-ext-test is now relocatable via TCNG_TOPDIR make tcsim-rpms now also generates tcng-tests RPM trimmed usage lines of tcc and tcsim to avoid wrap-around if installed at default location

tcng-6d (11-OCT-2001)

tcng-6d.tar.gz (277 kB) Changes: added more regression tests for fields (tests/field2) fields in variables were expanded too early, i.e. at the time of assignment instead of at the time of use (moved tests from tests/misfeatures to tests/tcng-6d) pseudo parameter names for meter macros can now be macros themselves (added tests to tests/meters) updated tests/expensive, tests/fastpath, and tests/tcm to use meters.tc instead of tcm.tc

tcng-6c (11-OCT-2001)

tcng-6c.tar.gz (276 kB) Changes: meters.tc: set_SLB sometimes used __dlb_ names, causing a variable uninitialized error (tests/tcng-6c) added tests for SLB and DLB macros, and the set_* macros of srTCM and trTCM (tests/meters)

tcng-6b (11-OCT-2001)

tcng-6b.tar.gz (275 kB) Changes: tcng expression syntax didn't include unary minus, oops :-) (tests/tcng-6b) tcc/LANGUAGE acknowledges that there are "standard" header files and naming conventions added tcc/meters.tc with improved TCM macros and single/double leaky bucket macros, obsoleting tcm.tc fields in variables are expanded too early, i.e. at the time of assignment instead of at the time of use, which can cause problems with preconditions (tests/misfeatures)

tcng-6a (10-OCT-2001)

tcng-6a.tar.gz (272 kB) Changes: extended tests/relop to check range 0-31 (was 0-16) to ensure better coverage of upper bits tcc, tcsim: added -X phase "p" for tcc's cpp (tests/phasep) tcng: the "warn" directive can now appear anywhere where variables or fields are allowed (tests/waprpos) tcng: the global pragma can now appear after global variables, fields, or "warn" directives (tests/waprpos) updated tcc/LANGUAGE accordingly, described pragmas, and renamed the "preamble" to "processing directives" tcng no longer allows the empty string as a pragma value (tests/pragma) tccext.c included keyword "pragma" among pragma values for qdiscs and classes (updated tests/pragma) tcng/README now recommends to download iproute2-2.2.4-now-ss001007.tar.gz instead of iproute2-current.tar.gz (this also affects build/tcsim.spec) build/Makefile: target "all" now depends on "rpmstuff"

tcng-5z (10-OCT-2001)

tcng-5z.tar.gz (271 kB) Changes: "C" target didn't support < or >= (tests/tcng-5z) iflib_bit.c did not recognize matches with values larger than the field size as always false (tests/tcng-5z) tcc can now translate relational operators with arbitrary constants (tests/relop) added list of unfiled items to TODO

tcng-5y (9-OCT-2001)

tcng-5y.tar.gz (270 kB) Changes: new option -Wexpensive to warn about expensive operations (as opposed to -E, which yields a fatal error; added tests to tests/expensive) variables can now be re-defined, just like fields (tests/varredef) new option -Wredefine (tests/varredef) updated tcc/LANGUAGE accordingly iflib_red.c:bundle could not handle multiple optimizations at the same level and has fence-post error when optimizing expressions of the type (ab || a) (tests/tcng-5y) updated tests/not accordingly oops, build/dummy.spec was never added (since tcng-5v)

tcng-5x (5-OCT-2001)

tcng-5x.tar.gz (268 kB) Changes: util.c: new function alloc_sprintf that acts as asprintf with error handling fixed about a dozen potential buffer overflows, many of them by using alloc_sprintf if_c.c: changed asserts on bucket/result overflow to errorf; moved array size definitions to config.h updated tests/additive according to above changes added and enabled data_destroy and data_destroy_1 fixed calls to data_destroy* iflib_act.c and iflib_arith.c, and access after destroy problems in iflib_red.c

tcng-5w (5-OCT-2001)

tcng-5w.tar.gz (267 kB) Changes: new external program tcc-ext-file that writes the configuration data to the file specified with -Xx,file= added tcc-ext-file to binary distributions child termination detection in tcc/ext_io.c was unnecessarily complicated and caused a race condition between child termination and processing of errors reported by child

tcng-5v (4-OCT-2001)

tcng-5v.tar.gz (267 kB) Changes: changed the names of filter.pl and plot.pl to tcsim_filter and tcsim_plot, respectively updated tcsim/README, scripts/symlinks.sh, scripts/runtests.sh, tests/pol_traffic, tests/tbf, tests/tcng-3i, and tests/usage accordingly scripts/runtests.sh: changed trinity.sh to "trinity" in order to eliminate last remaining bash-ism updated tests/ext, tests/tcng-2u, and tests/usage accordingly build/tcng.spec.in: split tcc RPM into tcc and tcc-devel added echoh.h to tcc-devel RPM Makefile: changed dependencies on ".distisuptodate" to the equivalent "dist" Makefile: added target "rmaltdist" to remove all binary distributions in tar.gz files or in RPMs, and any SRPMs, leaving only source distributions created with "make dist" "make rpm" now symlinks tcng source instead of copying it added experimental spec file build/tcsim.spec.in and helper file build/dummy.spec to build tcsim RPM (use with make tcsim-rpms ) Makefile: re-structured RPM-related targets TCSIM_BINDIST now also includes directories lib/tcng/include/klib/include and lib/tcng/include/klib/kernel/include added missing dependency of tcsim on symlinks

tcng-5u (3-OCT-2001)

tcng-5u.tar.gz (265 kB) Changes: TODO: removed obsolete remark about bubble_and tcc: removed obsolete options -A, -C, and -F tcc: new option -W[no]... to enable/disable specific warnings -Wtruncate enables warning when truncating value ranges (disabled by default; used to be always enabled) updated tests/tcng-2e accordingly -Wnounused disables unusued variable warning (enabled by default) updated tests/devbra and tests/tcng-5g (also removing several of useless -w), and tests/extlocbas and tests/misfeatures accordingly, i.e. by changing -w to -Wnounused tcng: new construct "warn [no]warning,..." to include -W options in configuration files (tests/warn) duplicate class selection paths are now valid, and are treated as distinct classes at top-level dsmark, in order to allow use of marking at top-level dsmark (tests/selpathdup) removed duplicate class selection path test from tests/selpath

tcng-5t.tar.gz (263 kB) Changes: tcc/ext/tccext.* added field "location" to TCCEXT_BLOCK, TCCEXT_QDISC, TCCEXT_CLASS, and TCCEXT_BUCKET, containing pre-formatted location string tcc/ext/echoh.*: added function echoh_buckets to print buckets tcc/ext/echoh.* now prints an error with location information and exits, if encountering pragma "force_failure" added regression tests for error feedback (tests/extlocext) tcc/ext/tccext.c:tccext_destroy did not free block->name tcc/ext.c no longer uses yyerror, because it's usually invoked either before parsing the first line or at EOF anyway removed tccext output formatting from TODO

tcng-5s (3-OCT-2001)

tcng-5s.tar.gz (262 kB) Changes: location specifications enclosed in [<...>] in standard error from external programs are now translated by tcc back to source code locations (tests/extlocbas) added new external program tcc-ext-xlat used by tests/extlocbas -Xx,fifos no longer attaches fifos to numbered dsmark classes (tests/tcng-5s, reported by Jacob) tcc now prints "expression" as the value of non-constant variables (tests/tcng-5s) updated tcc/README accordingly child process for external program executed exit handler, causing attempt to unlink input file twice, which failed, and output file was not deleted as a consequence (tests/tcng-5s, reported by Jacob)

tcng-5l (25-SEP-2001)

tcng-5l.tar.gz (256 kB) Changes: scripts/symlinks.sh still created obsolete links to kmod_cc and tcmod_tcc in tcng/bin tcc-ext-test.in still expected kmod_cc and tcmod_cc in $TOPDIR/bin, not $TOPDIR/lib/tcng/bin scripts/localize.sh now allowed environment variable TCNG_INSTALL_CWD to override its notion of the current directory "make all" and "make install" now automatically skip tcsim if disabled in configuration added tcc RPM spec file tcng/tcc.spec.in, and Makefile target "rpm"

tcng-5k (25-SEP-2001)

tcng-5k.tar.gz (255 kB) Changes: added assorted regression tests using class variables (tests/classvar) new directory locations: tcc-module, tcc-ext-err, kmod_cc, and tcmod_cc now go into $TOPDIR/lib/tcng/bin instead of $TOPDIR/bin libtccext.a, tcm_cls.c, and tcm_f.c now go into $TOPDIR/lib/tcng/lib instead of $TOPDIR/lib tccext.h, echoh.h, fields.tc, ip.def, tcngreg.def, and the symbolic links to tcsim/klib and tcsim/ulib now go into $TOPDIR/lib/tcng/include instead of $TOPDIR/include updated scripts/symlinks.sh, Makefile, scripts/localize.sh, tcc/tcc.c, tcc/if_c.c, tcc/tcc-module.in, tcc/ext/tcc-ext-test.in, tcsim/tcsim.c, tcsim/modules/kmod_cc.in, and tcsim/modules/tcmod_cc.in accordingly moved toys/tcm.tc to tcc/tcm.tc (and $TOPDIR/lib/tcng/include) updated tests/expensive, tests/fastpath, and tests/tcm accordingly tcc/ext_io.c now adds $TOPDIR/lib/tcng/bin to the PATH removed now unnecessary PATH=$PATH:tcc/ext from the following tests: arith, bitopt, cbqroot, classvar, defifo, drop, dsind, expensive, ext, extcbq, extflt, extmult, extndm, extqch, fastpath, field, fredef, location, misfeatures, not, phasex, pol_ext, setpathext, tcm, tcng-2u, tcng-3b, tcng-3h, tcng-3m, tcng-3n, tcng-3p, tcng-3r, tcng-3s, tcng-4a, tcng-4c, tcng-4d, tcng-4f, tcng-4h, tcng-4j, tcng-4l, tcng-4n, tcng-4p, tcng-4u, tcng-4w, tcng-4z, tcng-5a, tcng-5j, and unspec updated kernel version example on tcng/README from 2.4.9 to 2.4.10

tcng-5i.tar.gz (253 kB) Changes: tcc: it is now an error to try to use the obsolete options -A, -C, and -F updated tests/defifo and tests/location accordingly iflib_red.c:bubble_or removed incorrect comment about side-effect of iflib_act.c:self_contained tcc: added new option -E to make tcc fail if encountering an "expensive" operation, such as negation (either explicitly or via !=, > or >=), or an action tree that is not self-contained (tests/expensive; suggested by Jacob) iflib_red.c:bubble_or now more aggressively eliminates right-hand side of logical and README and configure: tcc is not compatible with kernel versions < 2.4.3

tcng-5h (20-SEP-2001)

tcng-5h.tar.gz (252 kB) Changes: tcc/iflib_red.c:iflib_normalize no longer bubbles actions through static classification in expressions ending in ... && (conditions || decision) (tests/fastpath; only with -N; suggested by Jacob) tcc/iflib_red.c:iflib_normalize makes expressions typical in simple multi color markers self-contained, thereby making above optimization possible in a wider range of cases (only with -N; tests/fastpath) toys/tcm.tc: added constrained versions of the color test macros, which tcc can process more easily. if_ext.c: removed redundant pass through iflib_normalize when using the "old" algorithm

tcng-5g (19-SEP-2001)

tcng-5g.tar.gz (251 kB) Changes: "make spotless" did not imply "make clean", leaving e.g. .symlinks TODO: documented tests/selpathgred incompatibility with older kernels added device and tunnel data types to simplify implementation of variable use scope information output variable use output (-u) now includes scope information updated tcc/README, tests/tcng-5f, and tests/varuse accordingly filters had no blank between "filter" and identifier in variable use output (tests/tcng-5g) added more precise location information to CBQ error messages (suggested by Jacob) updated tests/cbqroot accordingly

tcng-5e (14-SEP-2001)

tcng-5e.tar.gz (247 kB) Changes: updated TODO to reflect changes in version 5d last two entries were missing in CHANGES section of version 5d tcc/README: documented the -u option tcc/LANGUAGE: documented class selection paths

tcng-5c.tar.gz (241 kB) Changes: tcc: new option -u var_use_file to write content of variables to the specified file (tests/varuse) variables before first implict device now really have global scope (tests/tcng-5c) unused global variables are reported at end of file (tests/tcng-5c) updated tests/tcng-3k accordingly tcsim/plot.pl: added PNG (-png) and JPEG (-jpeg) output (based on patch by Gautam and Nikhil Thaker) dsmark no longer complains if class with a number above "indices" sets "mask" or "value" to values that imply no change (tests/dsind) dsmark: "indices" is now optional, and set to the next power of two above the highest class number (tests/dsind) q_dsmark.c: changed diagnostics to provide better location data updated tests/tcng-1i accordingly configure now exits on the first error tcsim/Makefile.ulib now invokes further makes with -e, to facilitate cross-compilation (reported by Langie Light)

tcng-5b (8-SEP-2001)

tcng-5b.tar.gz (239 kB) Changes: added new debugging function debugf2 that prints if debug > 1 scripts/symlinks.sh no longer prints the names of directories in "list" mode (this broke "make spotless") added "new" bit graph algorithm in tcng/tcc/iflib_newbit.c (it's completely useless at the moment) tcc: new undocumented option -N to select "new" bit graph algorithm

tcng-5a (30-AUG-2001)

tcng-5a.tar.gz (230 kB) Changes: added helper functions for run-time measurement (start_timer, print_timer) fixed uninitialized variable bug in tcc/if_u32.c:dump_offset fixed harmless uninitialized variable warnings in tcc/iflib_bit.c:{dump_static,dump_all_paths_to} file names containing blanks or other unprintable characters are now printed as in location map (tests/tcng-5a) empty strings are no longer allowed as tags (tests/tcng-5a) added new reporting functions lwarn and lwarnf changed most yy{error,warn}* to l{error,warn}* in ext_all.c, if_c.c, and if_ext.c updated tests/additive, tests/extcbq, tests/extflt, and tests/extndm accordingly iflib_bit.c now validates reference counts after all major operations unless NDEBUG is defined iflib_bit.c:{bubble_static,swap_bits} were badly broken (tests/tcng-5a, reported by Jacob) when debugging (-d), iflib_bit.c:unique_state validates that all bit types are still valid (they become invalid if free'ing a bit still in use) unique_state now eliminates bits when discovering that they are redundant (bit->true == bit->false), yielding more compact results adapted tests/tcng-4p accordingly

tcng-4z (29-AUG-2001)

tcng-4z.tar.gz (228 kB) Changes: tcc/police.c:assign_policer_ids was only invoked once, but more policers could be defined afterwards (tests/tcng-4z, reported by Jacob) configure, scripts/runtests.sh, and scripts/symlinks.sh assumed that the shell looks for files to source in the current directory instead of following the PATH if no explicit path is given (reported by Jacob) configure now reports loading defaults from old config file configure is now compatible with 2.4.10 (pre-release, tested with pre2)

tcng-4x (23-AUG-2001)

tcng-4x.tar.gz (227 kB) Changes: removed useless -I- from tcsim/Makefile new binary distribution target bindist-tcng-tests added (not generally useful yet) extended scripts/runtests.sh to take TOPDIR and TCNG_TOPDIR from the environment, and to use reasonable defaults if "config" is absent modified scripts/trinity.sh.in to use environment variable TCNG_TOPDIR (if present) instead of configured-in TOPDIR Makefile: added target "scripts" (how did scripts/trinity.sh ever get built without ??) changes names of binary distribution files from -.tar.gz to --bin.tar.gz tcc/config.h:TCC_MODULE_CMD always used hard-coded TOPDIR instead of allowing TCNG_TOPDIR override configure: new options --big-endian (-b) and --little-endian (-l) to set the bytesex configure: now also "inherits" bytesex from old config file

tcng-4w (22-AUG-2001)

tcng-4w.tar.gz (226 kB) Changes: fixed a few glitches in the CHANGES section of 4v updated tcsim/setup.klib to handle max(type,a,b) macro introduced in 2.4.9 updated kernel version example on tcng/README from 2.4.7 to 2.4.9 fields now have scoping, like variables (tests/tcng-4w) updated tests/misfeatures and tests/fredef accordingly (moved old misfeature test to tests/tcng-4w, but moved one now broken test from tests/fredef to tests/misfeatures and added new tests for similar problem with variables) devices now have optional braces around their qdiscs in order to avoid ambiguous variable scope (tests/devbra) updated tcc/LANGUAGE according to the two changes above tcc: added option -w to suppress all warnings

tcng-4v (22-AUG-2001)

tcng-4v.tar.gz (225 kB) Changes: configure: added option --no-tcsim (abbreviation -n) to enable build of tcc only top-level make now refuses all targets depending on tcsim, and build-test if tcsim is disabled in configuration removed unnecessary inclusion of ../../config from tcsim/modules/Makefile (caused complaint on make cvsupdate in virgin tree) scripts/symlinks.sh now sources "config" only if linking (unconditional sourcing caused complaint on make cvsupdate in virgin tree) tcc now sorts sibling classes by class ID (tests/sort; suggested by Jacob) updated tests/extqch accordingly tcc now allows fields to be re-defined wherever one can put a variable assignment (tests/fredef) known bug: fields still have global scope (tests/misfeatures)

tcng-4u (16-AUG-2001)

tcng-4u.tar.gz (224 kB) Changes: configure is now compatible with 2.4.9 (pre-release, tested with pre4) tcc/README: "Invocation" section was obsolete and incorrect (reported by Mika Yrjola) added realistic tcc example in tcc/example tcsim: added option -c to perform only syntax check new test tests/examples checks all examples in examples/*, examples-ng/*, and tcc/example for correct syntax tcsim/setup.klib now skips cls_u32.c patch applied somewhere in 2.4.8-pre* dump_if_u32 now also handles negation updated tests/tcng-3g accordingly location map used "file:line", not "file line" as described in README location map now uses "-" instead of empty string to indicate stdin. Clarified tcc/README accordingly. updated tests/location and tests/tag according to above changes dsmark did not adjust parent qdisc when resolving class 0 collision (tests/tcng-4u) inner qdisc of explicit CBQ root class was not dumped on tc (tests/tcng-4u) CBQ messed up order of filters on parent and root (which are the same), so now tcc refuses this bizarre combination (tests/tcng-4u) -B now sorts bits (in a very ugly way), just like without -B (tests/tcng-4u)

tcng-4t (10-AUG-2001)

tcng-4t.tar.gz (222 kB) Changes: split make target "bindist" into "bindist-tcc" and "bindist-tcsim" added missing target "tcsim" to tcng/Makefile

tcng-4s (9-AUG-2001)

tcng-4s.tar.gz (222 kB) Changes: "make clean" in tcng/tcsim tried to access klib/ulib, which may not exist after partial build forgot to include scripts/localize.sh in distribution

tcng-4r (9-AUG-2001)

tcng-4r.tar.gz (222 kB) Changes: added tcng/tcc/ext/tcc-ext-err to tcng/bin modified tcc/tcc.c, tcc/tcc-module.in, tcsim/tcsim.c, tcsim/modules/kmod_cc.in, and tcsim/modules/tcmod_cc.in to use environment variable TCNG_TOPDIR (if present) instead of compiled-in TOPDIR added option --install-directory (or -d) to configure added "make install" target and "make bindist" targets new script scripts/localize.sh to generate wrapper scripts for tcc and tcsim tcc/Makefile now uses scripts/topdir.sh to build tcc-module described installation procedure in tcng/README

tcng-4q.tar.gz (221 kB) Changes: added new target "ephemeral" to most Makefiles added new target "cvsupdate" to top-level Makefile, which removes ephemeral files from CVS' list added scripts scripts/cvsupdate.sh invoked for above target added new target "bindist" to top-level Makefile to build binary distributions of tcc and tcsim scripts/symlinks.sh now accepts the mode of operation as its first argument ("list" or "link") fixed various files forgotten by "make clean" and such

tcng-4p (8-AUG-2001)

tcng-4p.tar.gz (220 kB) Changes: optimized iflib_bit.c:clear_counters (from O(2^N) worst-case to O(N)) added new field BIT.dump_number to optimize iflib_bit.c:deassign_numbers (from O(2^N) worst-case to O(N)) slightly improved heuristic used by iflib_bit.c:pick_best to produce up to 80% fewer matches updated tests/tcng-3r accordingly copy_list selected first, not last common node, confusing eliminate_bundle (tests/tcng-4p) tcng/tcc/Makefile did not use CC_OPTS (from tcng/Common.make)

tcng-4o (7-AUG-2001)

tcng-4o.tar.gz (219 kB) Changes: added more compact test case for bug fixed in 4n (tests/tcng-4n) added more precise location information to dsmark_default_class error message updated tests/defdsm accordingly dsmark failed to merge auto-generated class 0 with explicitly specified class 0, yielding duplicate class 0 (tests/tcng-4o; reported by Jacob) tccext.c did not find nested classes and therefore erroneously created dummy classes (tests/tcng-4o; reported by Jacob) fixed tests/extqch accordingly

tcng-4n (3-AUG-2001)

tcng-4n.tar.gz (218 kB) Changes: tcc/iflib_bit.c:swap_bits did not distinguish true and false, causing tcc to crash (tests/tcng-4n)

tcng-4m (3-AUG-2001)

tcng-4m.tar.gz (218 kB) Changes: tests/location did not include test for ingress qdisc error.h: added new error reporting functions lerror, lerrorf, vlerrof improved reporting of error location in parameter handling updated tests/tcng-2e accordingly

tcng-4k.tar.gz (217 kB) Changes: tcc: undocumented options -A, -C, -F now print warning tcc-ext-test now accepts "nounspec" argument, and echoes it in config mode updated tests/defcbq, tests/defdsm, tests/defifo, tests/extflt, tests/extmult, tests/extndm, tests/extqch, tests/location, tests/pragma, tests/tcng-3m, tests/tcng-3s, tests/tcng-4a, tests/tcng-4d, tests/tcng-4f, and tests/unspec to no longer use undocumented options, or to suppress the warning callers of scripts/runtests.sh can now pass file name information using a FILE directive q_cbq.c now always generates an explicit root class, if none is present (tests/cbqroot) updated tests/extndm, tests/extqch, tests/location, tests/tcng-1n, tests/tcng-2c, tests/tcng-2h, and tests/tcng-4f accordingly q_cbq.c combines the root class with the qdisc when generating tc output (tests/cbqroot) qdisc.c:make_class did not initialize all fields of new class, causing stray problems with require_class

tcng-4j (24-JUL-2001)

tcng-4j.tar.gz (215 kB) Changes: tccext: moved actions and rules from global scope to block scope updated tccext.h, tccext.c, echo.c, and tests/tcng-3s accordingly tcc/ext/match.c now detects and refuses multiple blocks (at run-time) tcc/ext/echo.c now prints offsets and buckets before blocks, to maintain at least some resemblance of order updated tests/pragma, and tests/tcng-3s accordingly suppressed cross-block sharing in if_ext_act.c (tests/extmult) CHANGES: tcng-4h entry for iflib_act problem was incomplete and also missing in TODO tcc/ext.c:ext_build used shadowed variable "name", yielding confusing reports lex hack to express if anchors conflicted with "drop if", causing enigmatic syntax errors (tests/tcng-4j) fields.tc: added field udp_data, for symmetry with TCP

tcng-4i (24-JUL-2001)

tcng-4i.tar.gz (214 kB) Changes: added runtests.sh, trinity.sh, topdir.sh, and configure to usage format checking (tests/usage) tcc, tcsim, runtests.sh: added new -X phase "x" or "x" to send command-line arguments to programs at tcc's external interface (tests/phasex) ext.c now prints standard output of external program when -d is set divided TODO into short-term and long-term issues ext_all now follows CBQ classes for further classification (tests/extcbq) removed corresponding misfeature test from tests/extflt ext_all now selects root class if classification fails completely in CBQ, instead of yielding an error (tests/extcbq) ext_all now refuses priomap parameter (tests/extcbq) qdisc.c:assign_class_id did not detect duplicate class IDs (tests/tcng-4i) variable scoping was outside-in (tests/tcng-4i) "drop" without selector now warns that it's useless (tests/tcng-4i)

tcng-4h (23-JUL-2001)

tcng-4h.tar.gz (213 kB) Changes: updated kernel version example on tcng/README from 2.4.6 to 2.4.7 external interface: there is now only a single action per action line, which simplifies the code and makes the data structures less ambiguous eliminated TCCEXT_ACTIONS and added "index" and "next" fields in TCCEXT_ACTION updated doc/external.tex accordingly updated tests/pragma, tests/tcm, and tests/tcng-3s accordingly oops, iflib_bit never emitted "action N" clauses (tests/tcng-4h) iflib_act.c:bubble_and turns Action && Match into M && A without considering possible side-effects of A or M (note: the resulting mess fails at later processing stages, so at least no incorrect output is generated)

tcng-4d (17-JUL-2001)

tcng-4d.tar.gz (203 kB) Changes: ext_all leaked default parameters among sibling classes (reported by Jacob) symbolic links are now generated by scripts/symlinks.sh for better CVS compatibility (suggested by Langie Light) link to echoh.h was missing in distribution when using -B, action "unspec" was called "continue" added draft description of new external protocol rules (doc/README.tccext) renamed tcc/ext.c to tcc/ext_io.c added prototype implementation of new external protocol tcc/ext: updated tcc-ext-err, echo.c, echoh_main.c, and tcc-ext-test.in accordingly made output selection in tests/ext less dependent on naming conventions of tcc-ext-test updates tests/tcng-3s to obey new calling conventions external program now needs to be available even if tcc faild before the build phase; updated tests/extflt accordingly dependency on "tcc" was missing for "make test"

tcng-4c (16-JUL-2001)

tcng-4c.tar.gz (201 kB) Changes: added trailing line of dashes to each test title added "drop if" construct, which is roughly synonymous to "class if (...) && drop" (tests/drop, tests/misfeatures) updated tcc/LANGUAGE accordingly accessing "raw" without specifying an index crashed iflib_off.c:use_offset added cases where bit strings are combined across presence boundaries to tests/misfeatures included TODO file

tcng-4b (14-JUL-2001)

tcng-4b.tar.gz (198 kB) Changes: tcsim: an end time can now be specified for "every" (suggested by Stefano Avallone; test in tests/until) added description of test writing concepts in tests/README verified that filter ID range is indeed 1..0xffff, as filter.c assumes ext_all.c:filter_path now checks that tcindex classifiers don't use policing (tests/extflt) ext_all.c:filter_path accessed prm_mask in element, where it doesn't exist (but by sheer luck happens to have the right value) tcng/README did not mention that also echoh is under the LGPL echoh_blocks now accepts a file argument, and tcc-ext-echoh prints on stderr, not stdout updated kernel version example on tcng/README from 2.4.3 to 2.4.6 runtests.sh now strips trailing line of dashes from test title, allowing writing of more easily readable test files

tcng-4a (13-JUL-2001)

tcng-4a.tar.gz (196 kB) Changes: tcc/param.c:param_print would de-reference NULL pointer on childless elements (reported by Jacob) Common.make didn't remove __*.in files generated at external interface ext.c did not clean up temporary files after error exit libtccext.a: added new function echoh_block to print qdisc/class hierarchy (suggested by Jacob) added link from include/echoh.h added corresponding external program tcc-ext-echoh tcc/ext_all.c:filter_path did shift before mask instead of mask before shift tcc/ext_all.c:filter_path messed up default parameters plot.pl now weights samples when calculating the average rate over multiple packets (based on a patch by Lars Wischhof)

tcng-3z (12-JUL-2001)

tcng-3z.tar.gz (195 kB) Changes: added patch to iproute2/tc to fix offset increment for data items larger than 4 bytes (patches/tc-u32-incr) new qdisc flags QDISC_CHILD_QDISCS and QDISC_SHARED_QDISC to indicate how many child qdiscs a qdisc can have new undocumented option -F to add FIFO qdiscs wherever a default qdisc is used (tests/defifo) tccext.h: clarified that TCCEXT_BLOCK.qdiscs points to the top-level qdisc started adding infrastructure for clean external interface protocol replaced huge "if_ext calls ext_all" hack by several smaller ones

tcng-3v (6-JUL-2001)

tcng-3v.tar.gz (188 kB) Changes: pragma on devices did not set param_def, which could crash tcc (test added to tests/pragma)

tcng-3u (6-JUL-2001)

tcng-3u.tar.gz (188 kB) Changes: in tccext, changed "queue" to "qdisc", "QUEUE" to "QDISC" added experimental module for dumping full configuration (activated with -A) tccext recognizes (and ignores) "class"

tcng-3t (4-JUL-2001)

tcng-3t.tar.gz (185 kB) Changes: configure is now compatible with 2.4.7 (pre-release) configure now takes defaults from old config file if one exists ip.def: UDP_HDR did not evaluate parameters (reported by Stefano Avallone) tcsim/modules/kmod_cc and scripts/runtests.sh used [ with == instead of =, causing problems with older versions of bash (reported by Nikhil Thaker)

tcng-3n (27-JUN-2001)

tcng-3n.tar.gz (177 kB) Changes: syntax "if conform ($p)" is now accepted policer variables can now be redefined (a syntax conflict was introduced in version 3k) greatly simplified the way how the "police" prefix is made optional data_equal: added assertion that arguments aren't operators added debugging output to tcc/var.c

tcng-3m (26-JUN-2001)

tcng-3m.tar.gz (177 kB) Changes: tcng language documentation update (use of bare words is discouraged, "police" keyword before variables is optional in if expressions, described "if" and related constructs) added tests for negation combined with field conditions (tests/field) dsmark complained about class for inner qdisc if using default parameters after negation, the && and || actions were not swapped, causing incorrect processing of multiple nested negations tcc/ext/match.c incorrectly refused to count packets for which not enough tokens were available policing may be too permissive if using "count" without prior "conform" (misfeature) tcsim used bit size to check room in byte-sized buffer tcsim did not check room for default size (one byte) tcsim now checks values of packet data for correct range require_class always searched for class 0, yielding incorrect default selections if such a class existed added missing tests for arithmetic replacement of non-equality (tests/arith)

tcng-3l (19-JUN-2001)

tcng-3l.tar.gz (174 kB) Changes: qdiscs now have flags expressing their capabilities more rigid checking for qdisc capabilities ingress, dsmark, and prio now generate default class selection (currently enabled with undocumented tcc option -C) added new action "unspec" which is taken in the absence of -C updated tests accordingly (ext, field, misfeature, not, tcng-2u) tcc now knows that # 1 "." from cpp really means ""

tcng-3k (18-JUN-2001)

tcng-3k.tar.gz (172 kB) Changes: tcc no longer warns when using "milli" for seconds "police" prefix before variable name is now optional likewise, "filter" prefix before variable name on "on" expression is now optional tcc incorrectly refused "eth0 $q = prio ..." tcc still refuses above assignment with default device (misfeature) tcc incorrectly refused use of qdisc variables at top level "mtu" is no longer required for policers if target is not "tc" updated tests according to above change (pol_ext, pol_traffic, pragma, tcng-3b, vartype)

tcng-3h.tar.gz (166 kB) Changes: tcm.tc overestimated tcc's clearvoyance skills by including "count" in negated expressions, from where it may not be removed in time action numbering did not work when "drop" was involved (it did not recognize that "drop" equals "drop", and generated a new inverted tree every time) scripts/runtests.sh now prints a grammatically correct message when there is only a single test

tcng-3g (12-JUN-2001)

tcng-3g.tar.gz (166 kB) Changes: if_ext_act.c now tries to use class numbers as action numbers in order to ease visual inspection (suggested by Jacob) updated tests accordingly (tests/field, tests/tcng-2u, tests/tcng-3b) fields.tc is now protected against multiple inclusion iflib_red.c:prune_shortcuts incorrectly reduced 0 || X to 1 op.c:unum1_eval incorrectly assumed operands were always constant added TCM design study in toys/tcm.tc

tcng-3f (11-JUN-2001)

tcng-3f.tar.gz (165 kB) Changes: added various simple arithmetic optimizations (iflib_arith.c) added corresponding tests in tests/arith tcsim crashed when device name was missing after "dev" u32 target now also supports boolean constants 0 and 1 disabled globbing in runtests.sh to allow the use of asterisks in titles iflib_reduce is no longer called by common if code in filter.c:if_dump_tc iflib_red.c:do_optimize_eq shifted the default mask in the wrong direction if_u32 still has problems with masks; recorded them in tests/misfeatures

tcng-3e (7-JUN-2001)

tcng-3e.tar.gz (162 kB) Changes: tcc: fields can now be redefined (added test tests/field) policing results can now be used explicitly in "if" expressions (see tests/lib/pol_single_drop.tcsim) added action "drop" to tccext

tcng-3d (7-JUN-2001)

tcng-3d.tar.gz (161 kB) Changes: configure is now compatible with 2.4.6 (pre-release) global "make" now also builds content of documentation directory new file tests/pol_traffic with "live" policing tests for "C" and "ext" policing in tcc/ext/match.c didn't work at all added "block" statement to external interface if_ext now sorts bits within the same match and offset group by offset updated regression tests according to above two changes forgot to include scripts/rlatex, oops

tcng-3c (5-JUN-2001)

tcng-3c.tar.gz (158 kB) Changes: ether_proto_print(ether_proto(N)) can now return different name than N, or number (to handle protocols unknown to tc, or known under a different name) policer list wasn't NULL-terminated major redesign of action handling in if_ext, resulting in more compact actions group added flag "combine" to iflib_offset to make optimizations suitably tame for if_ext (reported by Jacob) above change makes if_ext generate less elegant offset expressions. Adjusted tests accordingly and moved old test to toys/reminiscence actions may now also include "action N" to point to that action. Updates documentation accordingly.

tcng-3b (1-JUN-2001)

tcng-3b.tar.gz (155 kB) Changes: moved runtests.sh to scripts/ where it rightfully belongs iflib_act issued redundant expressions, creating the impression that they were not self-contained moved action_tree from if_ext.c to iflib_act.c action_tree now knows that C || X is an action tree (C = self-contained) iflib_act incorrectly walked into action trees when walking an || chain, making incorrect transformations README still pointed to old download location (reported by Jacob) moved protocol/host/port lookups from tcng.y to new file named.c all filters: new parameter "protocol" to set ether protocol (suggested by Steven Van den Berghe) added a bunch of tests for named items (tests/named)

tcng-3a (1-JUN-2001)

tcng-3a.tar.gz (153 kB) Changes: if_ext now moves policing below matches (using iflib_act.c) if_ext now detects redundant or conflicting tests and reduces matches/rules accordingly if_ext now maintains an actions registry, eliminating the shared counter hack added regression tests for above to tests/pol_ext and tests/ext added tests for things to fix: tests/misfeatures
