It could happend in functions: _nss_ldap_getnetbyname_r _nss_ldap_getnetbyaddr_r _nss_ldap_gethostbyname2_r _nss_ldap_gethostbyaddr_r Fixes r548 (aka afd5d9b). --- nss/hosts.c | 2 -- nss/networks.c | 2 -- 2 files changed, 4 deletions(-) diff --git a/nss/hosts.c b/nss/hosts.c index 7773895..eda739b 100644 --- a/nss/hosts.c +++ b/nss/hosts.c @@ -51,8 +51,6 @@ #undef ERROR_OUT_BUFERROR #define ERROR_OUT_BUFERROR(fp) \ - (void)tio_close(fp); \ - fp = NULL; \ *errnop = ERANGE; \ *h_errnop = TRY_AGAIN; \ return NSS_STATUS_TRYAGAIN; diff --git a/nss/networks.c b/nss/networks.c index 6d12ca6..b18d5ca 100644 --- a/nss/networks.c +++ b/nss/networks.c @@ -51,8 +51,6 @@ #undef ERROR_OUT_BUFERROR #define ERROR_OUT_BUFERROR(fp) \ - (void)tio_close(fp); \ - fp = NULL; \ *errnop = ERANGE; \ *h_errnop = TRY_AGAIN; \ return NSS_STATUS_TRYAGAIN; -- cgit v1.2.3
