From 648c3b4e18b2ce2b6af7d44783e42ca267ea49f5 Mon Sep 17 00:00:00 2001 From: Rich Felker Date: Fri, 19 Jul 2013 01:34:28 -0400 Subject: change uid_t, gid_t, and id_t to unsigned types this change is both to fix one of the remaining type (and thus C++ ABI) mismatches with glibc/LSB and to allow use of the full range of uid and gid values, if so desired. passwd/group access functions were not prepared to deal with unsigned values, so they too have been fixed with this commit. --- src/passwd/getgrent_a.c | 11 +++++++++-- src/passwd/getpwent_a.c | 15 +++++++++++---- 2 files changed, 20 insertions(+), 6 deletions(-) (limited to 'src/passwd') diff --git a/src/passwd/getgrent_a.c b/src/passwd/getgrent_a.c index 780560dd..2cb85215 100644 --- a/src/passwd/getgrent_a.c +++ b/src/passwd/getgrent_a.c @@ -1,6 +1,13 @@ #include "pwf.h" #include +static unsigned atou(char **s) +{ + unsigned x; + for (x=0; **s-'0'<10U; ++*s) x=10*x+(**s-'0'); + return x; +} + struct group *__getgrent_a(FILE *f, struct group *gr, char **line, size_t *size, char ***mem, size_t *nmem) { ssize_t l; @@ -24,8 +31,8 @@ struct group *__getgrent_a(FILE *f, struct group *gr, char **line, size_t *size, *s++ = 0; gr->gr_passwd = s; if (!(s = strchr(s, ':'))) continue; - *s++ = 0; gr->gr_gid = atoi(s); - if (!(s = strchr(s, ':'))) continue; + *s++ = 0; gr->gr_gid = atou(&s); + if (*s != ':') continue; *s++ = 0; mems = s; break; diff --git a/src/passwd/getpwent_a.c b/src/passwd/getpwent_a.c index 1bd7f4fc..34842a07 100644 --- a/src/passwd/getpwent_a.c +++ b/src/passwd/getpwent_a.c @@ -1,6 +1,13 @@ #include "pwf.h" #include +static unsigned atou(char **s) +{ + unsigned x; + for (x=0; **s-'0'<10U; ++*s) x=10*x+(**s-'0'); + return x; +} + struct passwd *__getpwent_a(FILE *f, struct passwd *pw, char **line, size_t *size) { ssize_t l; @@ -23,11 +30,11 @@ struct passwd *__getpwent_a(FILE *f, struct passwd *pw, char **line, size_t *siz *s++ = 0; pw->pw_passwd = s; if (!(s = strchr(s, ':'))) continue; - *s++ = 0; pw->pw_uid = atoi(s); - if (!(s = strchr(s, ':'))) continue; + *s++ = 0; pw->pw_uid = atou(&s); + if (*s != ':') continue; - *s++ = 0; pw->pw_gid = atoi(s); - if (!(s = strchr(s, ':'))) continue; + *s++ = 0; pw->pw_gid = atou(&s); + if (*s != ':') continue; *s++ = 0; pw->pw_gecos = s; if (!(s = strchr(s, ':'))) continue; -- cgit v1.2.1
