2010-09-14Protect exec from memory faultsSamuel Thibault
* exec/exec.c (load_section): Call i`hurd_safe_copyin' instead of `memcpy'. Handle error case. (check_gzip): Likewise. (check_bzip2): Likewise.

2010-08-31Document incoherency for storage of task_events_infoSamuel Thibault
It doesn't produce any bug ATM just because GNU Mach does not support it. * libps/ps.h (struct proc_stat): Document that task_events_info is currently actually fetched into proc_info.

2010-08-27Revert "Fix tmpfs assertion"Samuel Thibault
As discussed up to http://lists.gnu.org/archive/html/bug-hurd/2010-06/msg00021.html this reverts commit 97c5690abeaa88767acf2ffbb55552e8278052c8 and removes the corresponding assertion. This is related to commit 2f7f90ce15cce79ef83a8d273e3a27b5b527c7d7 which changes how much st_size is increased. * tmpfs/tmpfs.h (tmpfs_dirent): Remove `padding' field. * tmpfs/dir.c (diskfs_get_directs): Remove assertion on the position of the `name' field of struct tmpfs_dirent compared to the position of the `d_name' field of struct dirent.

2010-08-27Keep a reference on objects to preserve their content.Samuel Thibault
Modify tmpfs to keep a reference (by mapping it into its own space) to each memory object created by the user, so they don't get inmediately terminated at the end of the current operation. * tmpfs/tmpfs.h (struct disknode): Add `memref' field. * tmpfs/node.c (diskfs_get_filemap): vm_map() the first page of the newly-allocated object, store in `memref' field. (diskfs_free_node) vm_deallocate the page pointed by `memref' field.
2010-08-27Fix default_pager default_pager_object_set_size parametersSamuel Thibault
As suggested by Sergio Lopez. * serverboot/default_pager.c (S_default_pager_object_set_size): Exchange `seqno' and `reply_to' parameters.
2010-08-27make unblocked reads from external objects return a zeroed page.Sergio Lopez
* serverboot/default_pager.c (struct dstruct): Add boolean_t external field. (default_pager_add): Set ds->external to TRUE or FALSE depending whether the object is external. (default_read): Add external parameter. If no_block(block) returns 1, if external is TRUE, zero fill the page and return PAGER_SUCCESS instead of PAGER_ABSENT. (seqnos_memory_object_data_request): Pass ds->external as additional parameter to default_read.
2010-08-27Fix missing mutex unlock.Sergio Lopez

2010-08-26libps (fetch_procinfo): Fix non-set flag PSTAT_TASK_EVENTSJeremie Koenig
The fetch_procinfo function failed to set the PSTAT_TASK_EVENTS when those has been retreived. It should be noted that GNU Mach does not support the TASK_EVENTS_INFO flavor, so this is of minor importance. The new code also checks that all the requested proc server flags related to a given proc_stat flags have been returned before setting the proc_stat flag in question. * libps/procstat.c (fetch_procinfo): Add map array containing `ps_flags_t' and `procinfo' flags. Use it in a loop to check for flags in `need' and `have' and set them in `pi_flags'. Likewise to check for flags in `pi_flags' and set them in `have'.
2010-08-26libps (_proc_stat_free): Fix memory leakJeremie Koenig
The thread_waits field was never freed; this change adds the code to do so if the corresponding flag is set. Users are also warned of the consequences, namely, that they should not free process proc_stats before all their associated thread ones are gone, since the latter may reference the former's thread_waits field. However, with the normal interface (ie. ps_context_free), all proc_stats are freed at once, so this is not an issue. * libps/procstat.c (_proc_stat_free): Free ps->thread_waits if PSTAT_THREAD_WAITS flag is set. * libps/ps.h (_proc_stat_free): Document that thread proc_stats must be freed before process proc_stat can be.
2010-08-26libps: Fix deadly typoJeremie Koenig
PSTAT_PROCINFO is a set of flags, some of which can be obtained in alternative ways. In this case, _proc_stat_free will try to deallocate an uninitialised field. PSTAT_PROC_INFO is the flag we want. * libps/procstat.c (_proc_stat_free): Use PSTAT_PROC_INFO instead of PSTAT_PROCINFO.
2010-08-18Fix the build system to handle part storesJeremie Koenig
Part stores are used for debian-installer, and they're considered more elegant than kernel partition devices. This patch makes sure they're included in the build unless the user disables them explicitely. * Makeconf: add $(PARTED_LIBS) to static binaries which use libstore_part.a. * configure.in: look for libparted again (see also 7c7a04eb). * libstore/Makefile (store-types): include the 'part' store type when appropriate, remove the previous attempt. Signed-off-by: Jeremie Koenig <jk@jk.fr.eu.org>

2010-08-01Fix "make dist" in `exec'.Ludovic Courtès
* exec/Makefile (SRCS): Refer to `$(gzip-sources)' and `$(bzip2-sources)' instead of listing files individually. (gzip-sources, bzip2-sources): New variable. (gzip-objects, bzip2-objects): Derive from the above variables.
2010-08-01Fix "make dist" in `daemons'.Ludovic Courtès
* daemons/Makefile (SRCS): Add `runsystem.sh'.
2010-08-01Fix "make dist" in `console-client'.Ludovic Courtès
This patch updates the list of headers to be included in the distribution, and makes it so that `kdioctlServer.c' isn't built and distributed by "make dist". * console-client/Makefile (PC_KBD_SO_SRCS): Remove `kdioctlServer.c'. (LCLHDRS): Remove `vga.h', add `vga-support.h' and `trans.h'. (OBJS): Add `kdioctlServer.o'. (pc_kbd.so.$(hurd-version)): Add dependency on `kdioctlServer_pic.o'.

2010-08-01Add wide character support to the Hurd consoleJeremie Koenig
* hurd/console.h (CONS_WCHAR_MASK, CONS_WCHAR_CONTINUED): New macros. * console/console.c: Include <locale.h> (main): Call setlocale. * console/display.c (display_output_one): Call wcwidth() to know the width of the character to be displayed. Iterate over this with to insert characters with the additional CONS_WCHAR_CONTINUED flag. Update screen_shift_right and display_record_filechange calls accordingly. * console-client/vga-dynafont.c (WCHAR_BOLD, WCHAR_ITALIC, WCHAR_MASK): Change macro values. (dynafont_new): Use glyph->bbox.{width,height} instead of df->font->bbox.{width,height}. (dynafont_change_font): Likewise. (dynafont_lookup_internal): Likewise. Mask out CONS_WCHAR_CONTINUED before calling bdf_find_glyph, but test it for the second position of a double-width glyph. (dynafont_activate): Enable 9-bit width only when font width is not dividable by 8.
2010-08-01Simplify error exit pathSamuel Thibault
* libpager/data-request.c (_pager_seqnos_memory_object_data_request): Use allow_release_out label instead of re-doing unlocks by hand.
2010-08-01Fix swap on large devicesJeremie Koenig
DEV_GET_SIZE values overflow with large devices, rather use DEV_GET_RECORDS. * mach-defpager/setup.c (S_default_pager_paging_storage): Use DEV_GET_RECORDS instead of DEV_GET_SIZE.
2010-08-01Implement file_replarent in libtrivfsJeremie Koenig
* libtrivfs/file-reparent.c (trivfs_S_file_reparent): Call trivfs_S_io_duplicate.
2010-08-01Fix libdiskfs bootstrap race conditionJeremie Koenig
exec_exec() probably triggers a call to file_exec(), so the exec server port needs to be cached earlier. * libdiskfs/boot-start.c: Move caching the exec server port to just after initializing it.
2010-07-27Fix -g/-m console vga driver optionsSamuel Thibault
* console-client/vga.c (parse_opt): Reverse -g and -m option effect to match documentation.

* pflocal/socket.c (S_socket_getopt): Add SO_TYPE support. (S_socket_setopt): Fix return value.
2010-06-30Revert "Call device_close on store closure"Samuel Thibault
This reverts commit 1bb5a381a2e2f345beb1ca8d019b6174b13bb125. storeio can actually pass the device port to other processes, through file_get_storage_info for instance, these may then want to use it, even after storeio has closed its port.
2010-06-28Fix memory leak on receive errorSamuel Thibault
* pfinet/io-ops.c (S_io_read): On error, free data array if it was allocated.
