2013-09-15hurd: add fsys_get_sourceJustus Winter
Return information about the source of the receiving filesystem. If the concept of a source is applicable, SOURCE should refer to the source of the receiving translator and should be a description considered appropriate in the context of the translator. For example for the case of block device based filesystems, SOURCE should be the file name of the underlying block device. * hurd/fsys.defs: Add fsys_get_source. * hurd/fsys_reply.defs: Add fsys_get_source.

2013-09-09mount: handle -t autoJustus Winter
Use libblkid to detect the filesystem type if "auto" is given as type. Remove the translator localization from main, this is also done in do_mount and any errors are propagated properly. This way "auto" is handled correctly if given on the command line or used as filesystem type in the fstab. * configure.ac: Add check for libblkid. * config.make.in: Make libblkid specific values available. * utils/Makefile: Use libblkid specific values. * utils/mount.c (DEFAULT_FSTYPE): Use "auto" as default type. (do_mount): Detect type using libblkid. (main): Drop translator localization.
2013-08-29Fix buildSamuel Thibault
* utils/umount.c: Do not include useless <blkid/blkid.h>.
2013-08-29trans: register symlink translators as importantJustus Winter
Register any symlink translators running as root as important processes at the proc server. * trans/symlink.c (main): Mark us as important.
2013-08-29mach-defpager: register mach-defpager translators as importantJustus Winter

2013-08-29libtrivfs: register libtrivfs-based translators as importantJustus Winter
Register libtrivfs-based translators running as root as important processes at the proc server. * libtrivfs/startup.c (trivfs_startup): Mark us as important.
2013-08-29libnetfs: register libnetfs-based translators as importantJustus Winter

2013-08-29init: Mark all of inits children and init itself as importantJustus Winter
This is based on a fragment of Guillem Jovers patch presented here: http://lists.gnu.org/archive/html/bug-hurd/2006-02/msg00081.html It has been refreshed, updated and the copyright year is adjusted properly. It has been complemented with the necessary features to address the issues the original patch set out to address, namely that killall5 freezes the proc translator before it tries to walk over /proc/*/stat to decide which process to kill. Prior to this patch (and the one marking the procfs server as important process), killall5 would deadlock trying to walk over the proc file system. Ironically it would not have killed any process later on even if it had the chance, since two values obtained from /proc/*/stat are currently hardcoded to zero in our procfs. Patches addressing the problem as a whole are prepared and will be sent as a follow up. * init/init.c (launch_core_servers): Mark init, auth, proc and fs servers as important. (start_child): Mark the real init as important. (S_startup_important_task): Mark exec server as important.

(S_proc_mark_important): New function. * proc/mgt.c (create_startup_proc): Mark init as important.
2013-08-29proc: make the function check_owner availableJustus Winter
Make the function check_owner available for use in other files. * proc/info.c (check_owner): Drop attributes static and inline. * proc/proc.h (check_owner): Add prototype.
2013-08-29Reserve RPC ID for proc_set_init_taskSamuel Thibault
* hurd/process.defs: Reserve RPC ID for proc_set_init_task. * hurd/process_reply.defs: Likewise. * hurd/process_request.defs: Likewise.

2013-08-29Merge branch 'master-merge2' into master-mergeSamuel Thibault
2013-08-29umount: add a umount utilityJustus Winter
This adds a umount utility that implements most of the functions that the Linux umount utility provides, especially that subset that is used by the Debian package initscripts. * utils/umount.c: New file.
2013-08-29libnetfs: handle dead-name notificationsJustus Winter
Handle dead-name notifications the same way libdiskfs does. In fact, dead-name.c is a verbatim copy with trivial modifications. It clears np->sockaddr if the dead name notification was for that port. * libnetfs/dead-name.c: New file. * libnetfs/Makefile (OTHERSRCS): Add dead-name.c.
2013-08-29libnetfs: implement file_get_translator_cntlJustus Winter
This is a trivially adapted version of libdiskfs/file-get-transcntl.c. * libnetfs/file-get-transcntl.c: New file.
2013-08-29daemons: fix setsid(2) in console-runJustus Winter
Only run setsid(2) if the process is not already the group leader. * daemons/console-run.c (open_console): Fix setsid(2).
2013-08-29hurd: add missing routines in process_reply.defsJustus Winter
Add the appropriate simpleroutine or skip directives to hurd/process_reply.defs matching the ones in hurd/process.defs. * hurd/process_reply.defs: Add missing routine declarations.
2013-08-29exec: remove the BFD codeJustus Winter
This commit removes the parts of the exec server that were once using the Binary File Descriptor library. As I understand it, the BFD code stopped working because it uses stdio streams and the glue code for that has never been ported to libio. The code has been #ifdefed out ever since. It may or may not work in its current state, so it is removed. If someone is interested, it can always be recovered from the version control system. * exec/exec.c: Remove all BFD related code. * exec/priv.h: Likewise. * TODO: Remove the corresponding item.
2013-08-28exec: Remove #ifdef 0-out code for user specified exec servers.Justus Winter
This code was meant to allow the user to specify alternative exec servers using an environment variable. The Hurd uses the file system as namespace for server lookups, so the proper way to use one's own exec server seems to be the remap translator. * exec/exec.c (S_exec_exec): Remove unused code.
2013-08-28Do not build gzip/bzip2 supportSamuel Thibault
* exec/Makefile (SRCS): Remove gzip and bzip2 sources. (OBJS): Remove gzip and bzip2 objects.
2013-08-28Disable transparent gzip/bzip2 decompressionSamuel Thibault
* exec/Makefile (CPPFLAGS): Do not define GZIP and BZIP2 macros.
2013-08-28utils: add nullauth utilityJustus Winter
nullauth drops all authentication credentials and runs the given program. This is also useful to drop privileges on behalf of translators that do not need any credentials in some circumstances, e.g. % settrans -ap /hurd/nullauth -- /hurd/storeio -Tzero makes storeio run without any credentials. * utils/nullauth.c: New file. * utils/Makefile: Build nullauth.
2013-08-28tmpfs: drop privileges in the tmpfs translatorJustus Winter
* tmpfs/tmpfs.c (main): Drop privileges.
2013-08-28trans: drop privileges in the null translatorJustus Winter
* trans/null.c (main): Drop privileges.
2013-08-28libshouldbeinlibc: Add nullauth.{c,h}Justus Winter
setnullauth () obtains an empty authentication handle and uses it for further authentication purposes. This effectively drops all Unix privileges. * libshouldbeinlibc/nullauth.c: New file. * libshouldbeinlibc/nullauth.h: Likewise. * libshouldbeinlibc/Makefile: Add nullauth.{c,h}.
2013-08-28console-client: add daemonizing supportJustus Winter
This patch adds daemonizing support using libdaemon. * console-client/console.c (daemonize): New variable. (options): Add --daemonize argument. (parse_opt): Handle --daemonize argument. (daemon_error): New error(3) like macro. (main): Daemonize. * console-client/Makefile: Use libdaemon specific build flags.
2013-08-28Add configure checks for libdaemonJustus Winter
* configure.ac: Add check for libdaemon. * config.make.in: Make the libdaemon specific variables available.
2013-08-28Define and use symbolic names for important processesJustus Winter
* include/pids.h: New file. * init/init.c (frob_kernel_process): Use symbolic name for kernel process. * exec/exec.c (S_exec_init): Use symbolic name for startup process. * libdiskfs/boot-start.c (diskfs_S_fsys_init): Likewise. * libdiskfs/init-startup.c (_diskfs_init_completed): Likewise. * pfinet/main.c (arrange_shutdown_notification): Likewise. * proc/mgt.c (create_startup_proc): Likewise. * proc/main.c (main): Use symbolic name for proc process.
