* Consistently use uintN_t not u_intN_t everywhere.Joseph Myers2017-08-076-29/+29
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch changes the remaining uses of the old nonstandard u_intN_t types in glibc to use the C99 uintN_t instead, except for the definitions of those typedefs and the tests of them in the c++-types test. This follows the previous such fix for libm, and being consistent in using uintN_t makes sense as a global cleanup. Tested for x86_64, and with build-many-glibcs.py. * catgets/catgets.c (catgets): Use uintN_t instead of u_intN_t. * catgets/catgetsinfo.h (struct catalog_obj): Likewise.

* resolv: Automatically reload a changed /etc/resolv.conf file [BZ #984]Florian Weimer2017-07-039-94/+235
| | | | | | | | | | This commit enhances the stub resolver to reload the configuration in the per-thread _res object if the /etc/resolv.conf file has changed. The resolver checks whether the application has modified _res and will not overwrite the _res object in that case. The struct resolv_context mechanism is used to check the configuration file only once per name lookup.
* resolv: Mirror the entire resolver configuration in struct resolv_confFlorian Weimer2017-07-036-116/+536
| | | | | | | | | | | | | | This commit adds the remaining unchanging members (which are loaded from /etc/resolv.conf) to struct resolv_conf. The extended name server list is currently not used by the stub resolver. The switch depends on a cleanup: The _u._ext.nssocks array stores just a single socket, and needs to be replaced with a single socket value. (The compatibility gethostname implementation does not use the extended addres sort list, either. Updating the compat code is not worthwhile.)
* resolv: Lift domain search list limits [BZ #19569] [BZ #21475]Florian Weimer2017-07-036-81/+348
| | | | | | | This change uses the extended resolver state in struct resolv_conf to store the search list. If applications have not patched the _res object directly, this extended search list will be used by the stub resolver during name resolution.
* resolv: Introduce struct resolv_conf with extended resolver stateFlorian Weimer2017-07-038-10/+452
| | | | | | | | | | | | This change provides additional resolver configuration state which is not exposed through the _res ABI. It reuses the existing initstamp field in the supposedly-private part of _res. Some effort is undertaken to avoid memory safety issues introduced by applications which directly patch the _res object. With this commit, only the initstamp field is moved into struct resolv_conf. Additional members will be added later, eventually migrating the entire resolver configuration.
* resolv: Introduce struct resolv_context [BZ #21668]Florian Weimer2017-07-0315-291/+810
| | | | | | | | | | | | struct resolv_context objects provide a temporary resolver context which does not change during a name lookup operation. Only when the outmost context is created, the stub resolver configuration is verified to be current (at present, only against previous res_init calls). Subsequent attempts to obtain the context will reuse the result of the initial verification operation. struct resolv_context can also be extended in the future to store data which needs to be deallocated during thread cancellation.

* resolv: Avoid timeouts in test-resolv-res-init, test-resolv-res_init-threadFlorian Weimer2017-06-271-0/+78
| | | | | | | Some Linux kernels have very aggressive ICMP rate limiting on the loopback interface. This commit introduces a minimal echoing DNS server inside the network namespace, so that there is no need for ICMP error messages anymore.
* resolv: Call _res_hconf_init from __res_vinitFlorian Weimer2017-06-272-1/+5
| | | | | | | | Many callers of __res_maybe_init also call _res_hconf_init. Additional calls to the latter do not hurt because the function does its work only once. (/etc/hosts.conf is not reloaded or even checked for changes.) This means that we can simplify the code by calling _res_hconf_init directly from __res_vinit.

* Include shlib-compat.h in many sunrpc/nis source files.Zack Weinberg2017-06-041-3/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Every file that uses libc_hidden_nolink_sunrpc or libnsl_hidden_nolink_def needs to include shlib-compat.h. Currently, most of them are getting it via stdio.h, because libio.h refers to SHLIB_COMPAT when _LIBC is defined, so it includes shlib-compat.h. My experimental patch to not install libio.h breaks that chain; stdio.h no longer pulls in libio.h even for internal users. Accordingly, this patch adds #include <shlib-compat.h> to many files in sunrpc/ and nis/. There are also a small number of really obvious fixups to includes that caught my eye while proofreading the patch - not including headers twice in a row, not worrying about portability to Ultrix anymore, sort of thing. * nis/nis_add.c, nis/nis_addmember.c, nis/nis_call.c * nis/nis_checkpoint.c, nis/nis_clone_dir.c, nis/nis_clone_obj.c * nis/nis_clone_res.c, nis/nis_creategroup.c, nis/nis_defaults.c * nis/nis_destroygroup.c, nis/nis_domain_of.c * nis/nis_domain_of_r.c, nis/nis_error.c, nis/nis_file.c * nis/nis_free.c, nis/nis_getservlist.c, nis/nis_ismember.c * nis/nis_local_names.c, nis/nis_lookup.c, nis/nis_mkdir.c * nis/nis_modify.c, nis/nis_ping.c, nis/nis_print.c * nis/nis_print_group_entry.c, nis/nis_remove.c * nis/nis_removemember.c, nis/nis_rmdir.c, nis/nis_server.c * nis/nis_subr.c, nis/nis_table.c, nis/nis_util.c * nis/nis_verifygroup.c, nis/nis_xdr.c, nis/yp_xdr.c * nis/ypclnt.c, nis/ypupdate_xdr.c, sunrpc/auth_des.c * sunrpc/auth_none.c, sunrpc/auth_unix.c, sunrpc/authdes_prot.c * sunrpc/authuxprot.c, sunrpc/clnt_gen.c, sunrpc/clnt_perr.c * sunrpc/clnt_raw.c, sunrpc/clnt_simp.c, sunrpc/clnt_tcp.c * sunrpc/clnt_udp.c, sunrpc/clnt_unix.c, sunrpc/des_crypt.c * sunrpc/des_soft.c, sunrpc/get_myaddr.c, sunrpc/key_call.c * sunrpc/key_prot.c, sunrpc/netname.c, sunrpc/pm_getmaps.c * sunrpc/pm_getport.c, sunrpc/pmap_clnt.c, sunrpc/pmap_prot.c * sunrpc/pmap_prot2.c, sunrpc/pmap_rmt.c, sunrpc/publickey.c * sunrpc/rpc_cmsg.c, sunrpc/rpc_dtable.c, sunrpc/rpc_prot.c * sunrpc/rpc_thread.c, sunrpc/rtime.c, sunrpc/svc.c * sunrpc/svc_auth.c, sunrpc/svc_raw.c, sunrpc/svc_run.c * sunrpc/svc_tcp.c, sunrpc/svc_udp.c, sunrpc/svc_unix.c * sunrpc/svcauth_des.c, sunrpc/xdr.c, sunrpc/xdr_array.c * sunrpc/xdr_float.c, sunrpc/xdr_intXX_t.c, sunrpc/xdr_mem.c * sunrpc/xdr_rec.c, sunrpc/xdr_ref.c, sunrpc/xdr_sizeof.c * sunrpc/xdr_stdio.c: Include shlib-compat.h. * sunrpc/des_crypt.c, sunrpc/des_soft.c: No need to include abi-versions.h as well as shlib-compat.h. * sunrpc/get_myaddr.c: Remove obsolete comment. * sunrpc/pmap_rmt.c: Remove obsolete comment and #undef. * sunrpc/rpc_thread.c: Include libc-lock.h only once. * resolv/res_libc.c: Include shlib-compat.h only once.

* Remove __need macros from signal.h.Zack Weinberg2017-05-201-2/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The types affected are __sig_atomic_t, sig_atomic_t, __sigset_t, sigset_t, sigval_t, sigevent_t, and siginfo_t. __sig_atomic_t is a scalar, so it's now directly available from bits/types.h. The others get bits/types/ headers. Side effects include: There have been small changes to which non-signal headers expose which subset of the signal-related types. A couple of architectures' nested siginfo_t fields had to be renamed to prevent undesired macro expansion. Internal code that wants to manipulate signal masks must now include <sigsetops.h> (which is not installed) and should be aware that __sigaddset, __sigandset, __sigdelset, __sigemptyset, and __sigorset no longer return a value (unlike the public API). Relatedly, the public signal.h no longer declares any of those functions. The obsolete sigmask() macro no longer has a system-specific definition -- in the cases where it matters, it didn't work anyway. New Linux architectures should create bits/siginfo-arch.h and/or bits/siginfo-consts-arch.h to customize their siginfo_t, rather than duplicating everything in bits/siginfo.h (which no longer exists). Add new __SI_* macros if necessary.

* Remove __need_list_t and __need_res_state.Zack Weinberg2017-05-203-78/+77
| | | | | | | | | | | | | | | | | | | | | | | | | These __need macros are only used internally, by nptl/descr.h. However, including all of resolv.h from descr.h causes build failures due to resolv.h's dozens of pseudo-struct-field macros, some of which collide with struct fields in NPTL internal data structures. Similarly, including all of list.h from descr.h produces an include cycle, atomic.h -> atomic-machine.h -> tls.h -> descr.h -> list.h -> atomic.h, and then list.h tries to use atomic.h macros that haven't been defined yet. So we do need mini-headers for these. In the list.h case I called it include/list_t.h since it isn't going to be installed. * resolv/resolv.h: Remove __need_res_state logic.

* Fix network headers stdint.h namespace (bug 21455).Joseph Myers2017-05-041-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | conform/ namespace tests of arpa/inet.h, netdb.h and netinet/in.h fail for UNIX98 and XPG42 because of inclusion of stdint.h, which defines macros not permitted in those headers for those standards. UNIX98 allows them to include inttypes.h, but (predating C99) has restricted inttypes.h contents (not yet tested in the conform/ tests) not including those macros; XPG4.2 has no such permission and no inttypes.h / stdint.h at all. This patch rearranges the headers to avoid this issue. intN_t definitions move to bits/stdint-intn.h, and uintN_t definitions to bits/stdint-uintn.h. (These are not bits/types/ headers because they each define four types. They are separate rather than just a single header because sys/types.h defines intN_t but u_intN_t rather than uintN_t - and while sys/types.h could define uintN_t because of the POSIX reservation of *_t, existing practice there is largely to condition types on appropriate feature test macros, and indeed there is at least one open bug report (14553) about a type that's not so-conditioned, so maybe types there should actually have conditions added where appropriate.) The affected network headers are then made to include bits/stdint-uintn.h instead of stdint.h. This allows six XFAILs to be removed. This doesn't do anything about inttypes.h defining more than it should for UNIX98, but we don't have conformtest expectations for that case at present (and my inclination is that a fix for that should be as local as possible - affecting only inttypes.h, not stdint.h, only for the case of __USE_UNIX98 && !__USE_ISOC99). Tested for x86_64.
