First, grepcidr.c is modified to use glibc's built-in getopt, rather than the getopt provided with the tarball. Second, regular expression support is added. A description of the regex patch by the original patch author is provided below. These two patches were combined because patch(1) does not seem to be able to handle the two "conflicting" changes when separated. ---------------------------------------------------------------------- Date: Fri, 29 Apr 2005 19:44:05 -0700 From: Jeff Makey The patch included below adds regular expression processing to allow grepcidr to find IP addresses anywhere on the input. Tested against the README file shipped with grepcidr-1.3, the first command below shows one line of output and the second correctly shows none: grepcidr 192.168.0.0/20 README grepcidr 192.168.16.0/20 README My changes work on Red Hat Linux 9.0, Sun Solaris, SGI IRIX, and IBM AIX. It should be possible to use regular expression processing and avoid calling sscanf() in the ip_to_uint() function, but it may not be worth the effort. Note that for a number the source lines the only thing I changed is the indenting. After applying the patch use "diff -w" to see just the coding changes. Thanks for writing grepcidr. Feel free to include this change in the next release. :: Jeff Makey jeff@sdsc.edu diff -ruN grepcidr-1.3-orig/grepcidr.c grepcidr-1.3/grepcidr.c --- grepcidr-1.3-orig/grepcidr.c 2005-04-23 15:00:16.000000000 -0700 +++ grepcidr-1.3/grepcidr.c 2006-10-05 01:42:24.000000000 -0700 @@ -25,7 +25,8 @@ #include #include #include -#include "getopt.h" +#include +#include #define EXIT_OK 0 #define EXIT_NOMATCH 1 @@ -164,6 +165,7 @@ char line[MAXFIELD]; int foundopt; int anymatch = 0; /* did anything match? for exit code */ + static regex_t preg; /* compiled regular expression for IPs */ if (argc == 1) { @@ -272,22 +274,35 @@ } } + /* Compile the regular expression for matching IP addresses */ + if (regcomp(&preg, "[0-9]+\\.[0-9]+\\.[0-9]+\\.[0-9]+", REG_EXTENDED) != 0) + { + (void)fputs("regcomp() failed\n", stderr); + return EXIT_ERROR; + } + /* Match IPs from input stream to network patterns */ while (fgets(line, sizeof(line), inp_stream)) { struct netspec key; - if ((key.min=ip_to_uint(line))) + regoff_t offset; + regmatch_t pmatch; + for (offset = 0; regexec(&preg, &line[offset], 1, &pmatch, 0) == 0; offset += pmatch.rm_eo) { - int match = 0; - if (bsearch(&key, array, patterns, sizeof(struct netspec), netsearch)) - match = 1; - if (invert ^ match) + if ((key.min=ip_to_uint(&line[offset + pmatch.rm_so]))) { - anymatch = 1; - if (counting) - counting++; - else - printf("%s", line); + int match = 0; + if (bsearch(&key, array, patterns, sizeof(struct netspec), netsearch)) + match = 1; + if (invert ^ match) + { + anymatch = 1; + if (counting) + counting++; + else + printf("%s", line); + break; + } } } } @@ -297,6 +312,7 @@ fclose(inp_stream); if (array) free(array); + regfree(&preg); if (counting) printf("%u\n", counting-1); debian/patches/01_makefile.patch0000664000000000000000000000151012237746044013723 0ustar ## makefile.patch by Ryan Finnie Index: grepcidr-1.3/Makefile =================================================================== --- grepcidr-1.3.orig/Makefile 2005-04-20 03:19:14.000000000 +0000 +++ grepcidr-1.3/Makefile 2013-11-10 18:10:38.595521231 +0000 @@ -3,21 +3,18 @@ # # Set to where you'd like grepcidr installed -INSTALLDIR=/usr/local/bin - -# Set to your favorite C compiler and flags -CC=gcc -CFLAGS=-s -O3 -Wall -pedantic - +PREFIX=/usr/local +BIN=$(PREFIX)/bin # End of settable values -grepcidr: - $(CC) $(CFLAGS) -o grepcidr grepcidr.c getopt.c +grepcidr: grepcidr.c + $(CC) $(CPPFLAGS) $(CFLAGS) -o grepcidr $(LDFLAGS) grepcidr.c all: grepcidr install: grepcidr - cp grepcidr $(INSTALLDIR) + install -d $(DESTDIR)$(BIN) + install ./grepcidr $(DESTDIR)$(BIN) clean: rm -f grepcidr *.o
