2020-12-14nsswitch: handle missing actions properlyDJ Delorie
Some internal functions need to know if a database has a nonzero list of actions; success getting the database does not guarantee that. Add checks for such as needed. Skip the ":" in each nsswitch.conf line so as not to add a dummy action libnss_:.so See also https://bugzilla.redhat.com/show_bug.cgi?id=1906066 Reviewed-by: Siddhesh Poyarekar <siddhesh@sourceware.org>
2020-12-04nsswitch: use new internal API (callers)DJ Delorie
Stitch new ABI and types throughout all NSS callers. Reviewed-by: Siddhesh Poyarekar <siddhesh@sourceware.org>
2020-07-08Remove --enable-obsolete-nsl configure flagPetr Vorel
this means that *always* libnsl is only built as shared library for backward compatibility and the NSS modules libnss_nis and libnss_nisplus are not built at all, libnsl's headers aren't installed. This compatibility is kept only for architectures and ABIs that have been added in or before version 2.28. Replacement implementations based on TIRPC, which additionally support IPv6, are available from <https://github.com/thkukuk/>. This change does not affect libnss_compat which does not depended on libnsl since 2.27 and thus can be used without NIS. libnsl code depends on Sun RPC, e.g. on --enable-obsolete-rpc (installed libnsl headers use installed Sun RPC headers), which will be removed in the following commit.

2019-05-15nss: Turn __nss_database_lookup into a compatibility symbolFlorian Weimer
The function uses the internal service_user type, so it is not really usable from the outside of glibc. Rename the function to __nss_database_lookup2 for internal use, and change __nss_database_lookup to always indicate failure to the caller. __nss_next already was a compatibility symbol. The new implementation always fails and no longer calls __nss_next2. unscd, the alternative nscd implementation, does not use __nss_database_lookup, so it is not affected by this change.

2017-08-14NSS: Replace exported NSS lookup functions with stubs [BZ #21962]Florian Weimer
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>.

2012-10-30Suppress incorrect link warnings for NSS symbolsChris Metcalf
When glibc is built with --enable-static-nss, the warning that using NSS symbols requires the nss shared objects to be present is no longer true, as those symbols are built into libc. Suppress the warning for those symbols by providing a new macro (nss_interface_function) for the NSS functions that is defined as static_link_warning in the normal case, and empty for static NSS.

2011-05-10More configurability for secondary group lookupUlrich Drepper
Together with a previous patch which introduced the initgroups entry in nsswitch.conf this patch allows more customization of the lookups for initgroups/getgrouplist. Nothing changes if the groups entry in nsswitch.conf is used. If the initgroups entry is used instead the code now doesn't automatically continue looking for more entries aftedr a successful lookup. Instead the normal rules are followed which do specify that by default no more service is consulted. This can be overwritten with [SUCCESS=continue] appropriately placed in the line.
