NSS: Replace exported NSS lookup functions with stubs [BZ #21962]
Commit 384ca551743318bd9c9e24a496d6397f2e3f2a49 from 2007 added this to
nss/XXX-lookup.c:
+#ifndef NO_COMPAT
+int
+internal_function attribute_compat_text_section
+DB_COMPAT_FCT (service_user **ni, const char *fct_name, void **fctp)
+{
+ return DB_LOOKUP_FCT (ni, fct_name, NULL, fctp);
+}
+#endif
That is, it adds a pseudo-compat function with an internal_function
attribute. The function it was supposed to replace did not have the
attribute:
extern int DB_LOOKUP_FCT (service_user **ni, const char *fct_name,
- void **fctp) internal_function;
+ const char *fct2_name, void **fctp)
+ internal_function;
This changed the calling convention on i386 for the following
functions in the public ABI:
__nss_passwd_lookup
__nss_group_lookup
__nss_hosts_lookup
This commit replaces the functions with always-failing stubs,
with true compat symbols. Due to a happy accident, the calling
convention of the stub is identical for the internal_function
and non-internal_function case on i386.
In addition, this commit auto-generates the __nss_*_lookup2
function declarations as part of <nsswitch.h>.
