* lib: early-include "config.h" in flex lexersDavid Lamparter2018-09-091-0/+5
| | | | | | This is neccessary to get _FILE_OFFSET_BITS right. Signed-off-by: David Lamparter <equinox@diac24.net>
* lib: ignore cli lexer in clang-analyzeQuentin Young2018-04-131-0/+5
| | | | | | | Lexer code is generated by Flex and we don't care about false positives in it. Signed-off-by: Quentin Young <qlyoung@cumulusnetworks.com>
* lib: fix more warnings on *BSDRenato Westphal2018-02-021-1/+2
| | | | | | | | | | | | | | | | | * zebra/kernel_socket.c: include "rt.h" to provide the prototypes of kernel_init() and kernel_terminate(); * lib/prefix.h: remove the deprecation warning whenever ETHER_ADDR_LEN is used. isisd uses the ETHER_HDR_LEN constant which is defined in terms of ETHER_ADDR_LEN in the *BSD system headers. So, when building FRR on *BSD, we were getting several warnings because we were using ETHER_ADDR_LEN indirectly; * lib/command_lex.l, lib/defun_lex.l: ignore other harmless warnings; * lib/spf_backoff.c: cast 'tv->tv_usec' to 'long int' before printing.

* *: support keywords that begin with uppercase letterDaniel Walton2017-09-141-3/+3
| | | | | | | | | | | Signed-off-by: Daniel Walton <dwalton@cumulusnetworks.com> VARIABLE tokens must be all uppercase, this allows us to support WORD tokens that begin with an uppercase letter. The "Null0" keyword is an example of where this is needed. The only VARIABLE we had that wasn't already all uppercase was ASN:nn_or_IP-address:nn
* lib: add CLI token for 48-bit mac addressesQuentin Young2017-08-111-0/+4

* lib: parser: fix allocation countingDavid Lamparter2017-01-311-7/+7
| | | | | | | command_lex.l was allocating as MTYPE_TMP, while command_parse.y would just call free(). Make both use MTYPE_LEX. Signed-off-by: David Lamparter <equinox@opensourcerouting.org>
* lib: parser: guard yyllocDavid Lamparter2017-01-241-2/+3
| | | | | | | yylloc seems to be NULL on parser init for some flex+bison combinations... Signed-off-by: David Lamparter <equinox@opensourcerouting.org>
* lib: parser: add error location reportingDavid Lamparter2017-01-231-1/+11
| | | | | | | | flex+bison have nice capabilities to track the location that is currently being processed; let's enable these and get better warnings for broken CLI specs. Signed-off-by: David Lamparter <equinox@opensourcerouting.org>
* lib: parser: free Mr. TDavid Lamparter2017-01-231-1/+1
| | | | | | | Mr. T was abducted by the parser and held hostage for ransom. Murdock was called, flew in and replaced him with a Tab character. Signed-off-by: David Lamparter <equinox@opensourcerouting.org>
* lib: parser: accept number-only word tokensDavid Lamparter2016-12-161-1/+1
| | | | | | | | There seems to be no reason why numbers don't work as plain word tokens; this is useful to have "number choices" or constants, e.g. <128|192|256> for bit encryption lengths. Signed-off-by: David Lamparter <equinox@opensourcerouting.org>
* lib: parser: reorder bison incarnationsDavid Lamparter2016-12-161-1/+0
| | | | | | | | | | | This shuffles the code blocks in command_parser.y to match file output order, then adjusts things to make the include handling less messy. (also dropped unused DECIMAL_STRLEN_MAX define.) This should hopefully fix the build on NetBSD 6. Signed-off-by: David Lamparter <equinox@opensourcerouting.org>
* lib: parser: use reentrant mode on flex & bisonDavid Lamparter2016-12-011-17/+21
| | | | | | | | | | | | This removes remaining global variables from the lexer, pushing the lexer state into struct parser_ctx too. At the same time, "cmd_yy" is used as prefix for all parser & lexer routines. The result is that (a) there is no collision anymore if a program uses flex/bison and links libzebra, and (b) the parser is fully encapsulated and could be called in parallel from multiple threads.

* lib: Allow nesting options in selectorsQuentin Young2016-09-181-5/+0
| | | | | | | Options may now be nested in selectors as long as they are not the first token in sequence. Signed-off-by: Quentin Young <qlyoung@cumulusnetworks.com>

* lib: Fix various minor bugsQuentin Young2016-08-091-3/+11

* lib: Fix OOB range parses, variable matchesQuentin Young2016-08-011-1/+5
| | | | | | | | Variables now allow strings beginning with numbers to match, ranges and numbers are now long long to fix OOB parses resulting in integer wraparounds. Signed-off-by: Quentin Young <qlyoung@cumulusnetworks.com>
* lib: Fixed bad node copy, modified token regexQuentin Young2016-08-011-2/+2
| | | | | | | | | | | When building argv for matched command, only the last node was being copied to argv; the rest were added by reference. Additionally the regex for certain tokens was too restrictive and disallowed characters allowed by the old parser; these have been reinstated.
