2011-01-16Fix child lookups relative to new homedirSamuel Thibault
* utils/login.c (main): Update `ports[INIT_PORT_CWDIR]' as soon as new cwd is determined according to HOME, since child lookups need to be relative to new homedir (e.g. for .hushlogin).
2011-01-16Fix comment typoSamuel Thibault
* utils/login.c (main): Fix comment typo.
2011-01-02Strictly adhere to the VGA register conventionSamuel Thibault
Not writing a value to the "enable display" register works for tested cards, but Linux writes a 0, and you can never know what manufacturers think. * console-client/vga-support.c (vga_exchange_palette_attributes): Write a 0 value to the "enable display" register.

2010-11-20Properly release console lock.Diego Nieto Cid
The console lock was released only when there were no allocation errors leaving it locked in the event mmap failed. This patch moves the mutex_unlock call to a point in the flow of control where it is consistent with the lock acquisition. * console/console.c(netfs_get_dirents): Relocate mutex_unlock call to common return path.

Compensate for any user-provided checksum. (rawv6_setsockopt): Reject odd checkum offsets with EINVAL. (rawv6_init_sk): Enable kernel-computed checksum by default for IPPROTO_ICMPV6 sockets.
2010-10-28Fix _ports_lock usageSamuel Thibault
* libports/create-internal.c (_ports_create_port_internal): Add label after mutex_unlock(_ports_lock), use it where appropriate.
2010-10-18Add \n to boot error messageSamuel Thibault
* boot/boot.c (main): Print \n after printing boot_script_error_string().
2010-10-11Fix return value on `getname' errors.Pino Toscano
This fixes the errno return value for getpeername() calls on not connected sockets: the return value of the `getname' call comes from the Linux code, so it is a negative value, in case of error. * pfinet/misc.c (make_sockaddr_port): Turn negative error values returned by `getname' calls into positive values before returning it.
2010-09-20Add device virtualisation support to bootZheng Da
* boot/boot.c: Add '-f' option. (dev_map): New structure. (dev_map_head): New variable. (add_dev_map): New function. (lookup_dev): New function. (parse_opt): Handle the '-f' option: call 'add_dev_map'. (ds_device_open): Try to call 'lookup_dev', and open the device from the device file if it succeeds.

2010-09-19Merge remote branch 'origin/master-zhengda'Samuel Thibault
Conflicts: utils/rpctrace.c
2010-09-19Fix port transmission over pflocalManuel Menal
* pflocal/socket.c (S_socket_recv): Return transmitted port to caller thanks to MACH_MSG_TYPE_COPY_SEND instead of MACH_MSG_TYPE_MAKE_SEND (since this is a send right here).
2010-09-18Obtain number of ports in proc and libpsantrik
Add (and implement) a proc RPC to obtain the number of Mach ports used by the target task. Add infrastructure in libps to read this information. * hurd/process.defs (proc_getnports): New RPC. * hurd/process_request.defs (proc_getnports_request): New RPC. * libps/procstat.c (proc_stat_set_flags): Call proc_getnports RPC if needed. * libps/ps.h (proc_stat): New `num_ports' field.

2010-09-14Fix in-memory mappingSamuel Thibault
* exec/exec.c (map): When e->file_data is not NULL, return it plus `posn'. (prepare_in_memory): Call prepare_stream to clear stream positions.

* libthreads/cthreads.h (mutex_try_lock): Call WAIT_SET_DEBUG when spin_try_lock succeeds.
2010-09-03WAIT_DEBUG: permit to get function names instead of threadsSamuel Thibault
From the idea of Sergio Lopez. * libthreads/cthreads.h [WAIT_FUNC_DEBUG] (mutex): Replace struct cthread *holder field with const char *fname. (WAIT_CLEAR_DEBUG, WAIT_SET_DEBUG): New macros which clear and set fname or holder according to WAIT_FUNC_DEBUG and WAIT_DEBUG being defined.

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.
2010-08-27Fix malloc size in tmpfsCarl Fredrik Hammar
* tmpfs/dir.c (diskfs_direnter_hard): Fix malloc size.

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
* serverboot/default_pager.c (pager_read_offset): Properly unlock the mutex before returning NO_BLOCK.
2010-08-26libps (proc_stat_set_flags): Fix pointer signedness warningJeremie Koenig

2010-08-26Merge branch 'master' of git.savannah.gnu.org:/srv/git/hurd/hurdSamuel Thibault
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.
