2015-09-06Fix race condition in ext2fs when remountingJames Clarke
On some systems, ext2fs.static would regularly hang at startup, as a race condition meant it would process paging requests while remounting. To fix this, libpager has been altered to allow inhibiting and resuming its worker threads, and ext2fs uses this to inhibit paging while remounting. * console/pager.c (pager_requests): New variable. (user_pager_init): Updated call to pager_start_workers to use new pager_requests variable. * daemons/runsystem.sh: Removed artificial delay working around the race condition. * ext2fs/ext2fs.c (diskfs_reload_global_state): Call new inhibit_ext2_pager and resume_ext2_pager functions, and leave sblock as non-NULL so it will be munmapped. * ext2fs/ext2fs.h (inhibit_ext2_pager,resume_ext2_pager): New functions. * ext2fs/pager.c (file_pager_requests): New variable. (create_disk_pager): Updated call to pager_start_workers to use new file_pager_requests variable. (inhibit_ext2_pager,resume_ext2_pager): New functions. * fatfs/fatfs.h (inhibit_fat_pager,resume_fat_pager): New functions. * fatfs/pager.c (file_pager_requests): New variable. (create_fat_pager): Updated call to pager_start_workers to use new file_pager_requests variable. (inhibit_fat_pager,resume_fat_pager): New functions. * libdiskfs/disk-pager.c (diskfs_disk_pager_requests): New variable. (diskfs_start_disk_pager): Updated call to pager_start_workers to use new diskfs_disk_pager_requests variable. * libdiskfs/diskfs-pager.h (diskfs_disk_pager_requests): New variable. * libpager/demuxer.c (struct pager_requests): Renamed struct requests to struct pager_requests. Replaced queue with queue_in and queue_out pointers. Added inhibit_wakeup field. (pager_demuxer): Updated to use new queue_in/queue_out pointers. Only wake up workers if not inhibited. (worker_func): Updated to use new queue_in/queue_out pointers. Final worker thread to sleep notifies the inhibit_wakeup condition variable. (pager_start_workers): Added out parameter for the requests instance. Allocate heap space shared by both queues. Initialise new inhibit_wakeup condition. (pager_inhibit_workers,pager_resume_workers): New functions. * libpager/pager.h (struct pager_requests): Public forward definition. (pager_start_workers): Added out parameter for the requests instance. (pager_inhibit_workers,pager_resume_workers): New functions. * libpager/queue.h (queue_empty): New function. * storeio/pager.c (pager_requests): New variable. (init_dev_paging): Updated call to pager_start_workers to use new pager_requests variable.

2014-11-21init: add a minimalist init programJustus Winter
This patch adds a minimalist init program. It is somewhat lacking in features, but is able to bring up a Hurd system with the runsystem and rc scripts. In fact, it roughly does what the former /hurd/init did, modulo all the very early bootstrapping stuff and the startup protocol. It is started when all the essential servers are up and running, so it can make use of most of the POSIX goodies, making its implementation much simpler. * Makefile (prog-subdirs): Add init. * daemons/runsystem.sh: Generalize runsystem so that it can start any init as specified on the kernel command line. By default, it starts /hurd/init. * daemons/runsystem.hurd: This is a verbatim copy of runsystem.sh. It is started by /hurd/init. * daemons/rc.sh: Do not start /hurd/mach-defpager as it is already started in runsystem.sh. * daemons/Makefile (SRCS): Add runsystem.hurd. * init/Makefile: New file. * init/init.c: Likewise.
2014-02-05daemons/getty: always print a newline before the bannerJustus Winter
* daemons/getty.c (load_banner): Drop first newline from default banner. (print_banner): Print a newline.
2014-01-31daemons/getty: display /etc/issue if availableJustus Winter
Previously, a banner was hardcoded in Hurds getty. Load /etc/issue instead. Fall back to a hardcoded version if that fails. Expand common \char sequences. If no /etc/issue is provided, the old behavior is retained. * daemons/getty.c (load_banner): New function. (print_banner): Expand \char sequences.
2013-10-28Make boot script accept more fsck valuesSamuel Thibault
* daemons/rc.sh: Accept fsck returning 5 and 9 too.
2013-10-22Make boot script reboot when fsck told soSamuel Thibault
* daemons/rc.sh: When fsck returned 2 or 3, reboot the system.
2013-09-19daemons: make sure / is writable before setting up pflocalJustus Winter
runsystem.sh checks whether /servers/socket/1 exists and creates it using settrans -c if it does not. But at this point in the boot the root filesystem is normally not writable. This patch fixes this. * daemons/runsystem.sh: Make sure / is writable before attempting to set up pflocal.
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).
2012-09-23Automatically setup local sockets if not already done so.Samuel Thibault
Needed early for shell pipelines. * daemons/runsystem.sh: See whether pflocal is setup already, and do so if not (install case)
2012-09-22Check that runsystem script exists before trying it.Samuel Thibault
* init/init.c (launch_something): Check with file_name_lookup that runsystem script exists before calling start_child. * daemons/console-run.c (main): Check with file_name_lookup that runsystem script exists before opening a console for it.
2012-04-08console-run: Create and settrans /dev/console when not already done.Ludovic Courtès
This patch makes sure /libexec/console-run creates and installs /dev/console on the first run without considering it a failure if it didn't exist already. * daemons/console-run.c (TERMINAL_FIRST_TRY): Change node to `/dev/console'. (TERMINAL_SECOND_TRY): Change node to `/tmp/console'. (open_console): Clear FALLBACK when TRY == 1 and the `file_set_translator' call suceeded.

* Fix spelling with codespell[1] and manually review it. [1] http://git.profusion.mobi/cgit.cgi/lucas/codespell/
2011-06-21Set default umask to 022Samuel Thibault
* daemons/runsystem.sh: Call umask 022.

* daemons/Makefile (SRCS): Add `runsystem.sh'.
