From 377747465843e328d600963d8b56a2c74483adba Mon Sep 17 00:00:00 2001 From: iwasaki Date: Tue, 30 May 2000 15:33:56 +0000 Subject: Add regex(3) matching feature for card line strings. - This feature will be enabled only if the string is enclosed by '/' something like; card "SunDisk" "/.*/" - Also added matching additional information strings followed by version string. This is for the card which is difficult to idendentify by only the manufacturer and card version strings matching. card "MACNICA" "MIRACLE SCSI" "mPS100" "D.0" Reviewed by: imp Obtained from: PAO --- usr.sbin/pccard/pccardd/cardd.c | 52 +++++++++++++++++++++++++++++++---- usr.sbin/pccard/pccardd/cardd.h | 2 ++ usr.sbin/pccard/pccardd/file.c | 30 +++++++++++++++++--- usr.sbin/pccard/pccardd/pccard.conf.5 | 10 +++++-- 4 files changed, 82 insertions(+), 12 deletions(-) (limited to 'usr.sbin/pccard/pccardd') diff --git a/usr.sbin/pccard/pccardd/cardd.c b/usr.sbin/pccard/pccardd/cardd.c index e8e1622..c8a5756 100644 --- a/usr.sbin/pccard/pccardd/cardd.c +++ b/usr.sbin/pccard/pccardd/cardd.c @@ -36,6 +36,7 @@ static const char rcsid[] = #include #include #include +#include #include #include "cardd.h" @@ -208,17 +209,44 @@ card_removed(struct slot *sp) /* CIS string comparison */ +#define REGCOMP_FLAGS (REG_EXTENDED | REG_NOSUB) +#define REGEXEC_FLAGS (0) + static int cis_strcmp(char *db, char *cis) { + int res, err; + char buf[256]; + regex_t rx; + char * p; size_t n; if (!db || !cis) { return -1; } n = strlen(db); - return strncmp(db, cis, n); - /* XXX Add code for regex CIS string comparison here */ + if (n > 2 && db[0] == '/' && db[n-1] == '/') { + /* matching by regex */ + db++; + } else { + /* otherwise, matching by strncmp() */ + return strncmp(db, cis, n); + } + p = xmalloc(n); + strncpy(p + 1, db, n-2); + *p = '^'; + db = p; + if ((err = regcomp(&rx, p, REGCOMP_FLAGS))) { + regerror(err, &rx, buf, sizeof buf); + logmsg("Warning: REGEX error for\"%s\" -- %s\n", p, buf); + regfree(&rx); + free(p); + return -1; + } + res = regexec(&rx, cis, 0, NULL, REGEXEC_FLAGS); + regfree(&rx); + free(p); + return res; } /* @@ -252,11 +280,23 @@ card_inserted(struct slot *sp) case DT_VERS: if (cis_strcmp(cp->manuf, sp->cis->manuf) == 0 && cis_strcmp(cp->version, sp->cis->vers) == 0) { + if (cp->add_info1 != NULL && + cis_strcmp(cp->add_info1, sp->cis->add_info1) != 0) { + break; + } + if (cp->add_info2 != NULL && + cis_strcmp(cp->add_info2, sp->cis->add_info2) != 0) { + break; + } + logmsg("Card \"%s\"(\"%s\") " - "matched \"%s\" (\"%s\") ", - sp->cis->manuf, sp->cis->vers, - cp->manuf, cp->version - ); + "[%s] [%s] " + "matched \"%s\" (\"%s\") " + "[%s] [%s] ", + sp->cis->manuf, sp->cis->vers, + sp->cis->add_info1, sp->cis->add_info2, + cp->manuf, cp->version, + cp->add_info1, cp->add_info2); goto escape; } break; diff --git a/usr.sbin/pccard/pccardd/cardd.h b/usr.sbin/pccard/pccardd/cardd.h index d983fcc..675cc5a 100644 --- a/usr.sbin/pccard/pccardd/cardd.h +++ b/usr.sbin/pccard/pccardd/cardd.h @@ -67,6 +67,8 @@ struct card { struct card *next; char *manuf; char *version; + char *add_info1; + char *add_info2; u_char func_id; int deftype; struct ether *ether; /* For net cards, ether at offset */ diff --git a/usr.sbin/pccard/pccardd/file.c b/usr.sbin/pccard/pccardd/file.c index 4857faf..0ed7e95 100644 --- a/usr.sbin/pccard/pccardd/file.c +++ b/usr.sbin/pccard/pccardd/file.c @@ -123,10 +123,14 @@ delete_card(struct card *cp) struct cmd *cmdp, *cmd_next; /* free characters */ - if (cp->manuf[0] != NULL) + if (cp->manuf != NULL) free(cp->manuf); - if (cp->version[0] != NULL) + if (cp->version != NULL) free(cp->version); + if (cp->add_info1 != NULL) + free(cp->add_info1); + if (cp->add_info2 != NULL) + free(cp->add_info2); /* free structures */ for (etherp = cp->ether; etherp; etherp = ether_next) { @@ -395,6 +399,7 @@ static void parse_card(int deftype) { char *man, *vers, *tmp; + char *add_info; unsigned char index_type; struct card *cp; int i, iosize; @@ -408,13 +413,30 @@ parse_card(int deftype) case DT_VERS: man = newstr(next_tok()); vers = newstr(next_tok()); + add_info = newstr(next_tok()); + if (keyword(add_info)) { + pusht = 1; + free(add_info); + cp->add_info1 = NULL; + cp->add_info2 = NULL; + } else { + cp->add_info1 = add_info; + add_info = newstr(next_tok()); + if (keyword(add_info)) { + pusht = 1; + free(add_info); + cp->add_info2 = NULL; + } else { + cp->add_info2 = add_info; + } + } cp->manuf = man; cp->version = vers; cp->func_id = 0; break; case DT_FUNC: - cp->manuf = ""; - cp->version = ""; + cp->manuf = NULL; + cp->version = NULL; cp->func_id = (u_char) func_tok(); break; default: diff --git a/usr.sbin/pccard/pccardd/pccard.conf.5 b/usr.sbin/pccard/pccardd/pccard.conf.5 index b1b26df..0f27bf2 100644 --- a/usr.sbin/pccard/pccardd/pccard.conf.5 +++ b/usr.sbin/pccard/pccardd/pccard.conf.5 @@ -141,7 +141,7 @@ defined. .Ss "Card Identifiers" The syntax for card identifiers is: .Pp -.Dl card Ar manufacturer version +.Dl card Ar manufacturer version [ add_info1 [ add_info2 ]] .Dl config Ar index driver interrupt [ flags ] .Dl ether Ar offset .Dl insert Ar command @@ -155,8 +155,14 @@ There may be multiple lines.
