I then removed trailing white space from math/tgmath.h,

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

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.
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.
Mark internal nss symbols with attribute_hidden to allow direct access
within libc.so and libc.a without using GOT nor PLT.
Tested on x86-64 with and without --disable-nscd.

Commit 384ca55174 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>.
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.
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.
