2014-02-22pfinet: set a non-zero ports management timeoutRichard Braun
* pfinet/main.c (main): Call ports_manage_port_operations_multithread with non-zero timeouts.
2014-02-22libports: work around bugs in server terminationRichard Braun
Most servers use ports_manage_port_operations_multithread to process requests and terminate when it returns. Since many of them don't detach before shutting down, a client may receive an error if its request arrived while the server is shutting down. Prevent those spurious errors by forcing ports_manage_port_operations_multithread not to return. * libports/manage-multithread.c (ports_manage_port_operations_multithread): Force global_timeout to 0.

2014-02-07trans/fakeroot: fix cached node retrieval on lookupRichard Braun
When a client finds a node from the hash table, it could happen that another thread is still holding one reference on it before the current thread has acquired its own. Simply checking for a non zero refcount isn't enough, the new client must atomically acquire its own reference. * trans/fakeroot.c (netfs_S_dir_lookup): Find and acquire node reference while holding netfs_node_refcnt_lock.
2014-02-06trans/fakeroot: fix netfs_S_dir_lookupRichard Braun
* trans/fakeroot.c (netfs_S_dir_lookup): Fix node dereference.
2014-02-05trans/fakeroot: rework node cachingRichard Braun
Instead of the FAKE_REFERENCE flag, rework node caching so that nodes are retained only if their attributes are actually changed. In addition, don't remove unreferenced nodes from the hash table at protid release, since their reference counter is unstable. Do it on node destruction, once the reference counter has reached 0. This means lookups can return nodes not referenced (other than by the hash table), a condition for which a check is added. By never acquiring a reference on such nodes, their counter is guaranteed to remain stable once unreferenced. * trans/fakeroot.c (FAKE_REFERENCE): Remove macro. (FAKE_DEFAULT): New macro. (set_default_attributes): New function. (set_faked_attribute): Likewise. (netfs_node_norefs): Remove node from hash table, properly taking care of all the locks involved. (fakeroot_netfs_release_protid): Remove node handling code, merely call netfs_release_protid. (netfs_S_dir_lookup): Handle unreferenced nodes, call set_default_attributes on node creation, remove call to netfs_attempt_chown. (netfs_attempt_chown): Call set_faked_attribute instead of accessing faked flags directly. (netfs_attempt_chauthor): Likewise. (netfs_attempt_chmod): Likewise. (main): Likewise.
2014-02-05trans/fakeroot: fix chmodRichard Braun
Unconditionally relay chmod requests instead of filtering those that don't change the executable bit. * trans/fakeroot.c (netfs_attempt_chmod): Unconditionally call file_chmod with an unaltered mode.

This reverts commit 672005782e57e049c7c8f4d6d0b2a80c0df512b4. That change is apparently not needed and introduced a deadlock. * trans/fakeroot.c (netfs_attempt_mkfile): Unlock directory node before creating new node.

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.

2014-01-19Rename variables with the name "error" to "err".Justus Winter
The canonical name for variables of the type error_t is err. There are, however, places where the variable is called error instead. This is unfortunate, as this shadows the error function. Rename such variables to err. For reference, this is accomplished using the following semantic patch: @@ expression E; @@ -error_t error = E; +error_t err = E; <... -error +err ...> @@ @@ -error_t error; +error_t err; <... -error +err ...> * libdiskfs/dir-link.c: Rename error to err. * libdiskfs/dir-unlink.c: Likewise. * libdiskfs/file-get-trans.c: Likewise. * libdiskfs/file-get-transcntl.c: Likewise. * libdiskfs/file-set-trans.c: Likewise. * libdiskfs/fsys-getroot.c: Likewise. * libshouldbeinlibc/wire.c: Likewise.
2014-01-16libps: fix task/thread times fetchingRichard Braun
Introduce PSTAT_TIMES to force the retrieval of both PSTAT_TASK_BASIC and PSTAT_THREAD_BASIC. Task basic info contain the user and system times of terminated threads which the code wrongly assumes is always present along with process info. * libps/procstat.c (add_preconditions): Set both PSTAT_TASK_BASIC and PSTAT_THREAD_BASIC as preconditions for PSTAT_TIMES. (summarize_thread_basic_info): Add terminated threads times only if task basic info are available. (set_procinfo_flags): Provide summarize_thread_basic_info with flags of available info. (proc_stat_set_flags): Set PSTAT_TIMES as available if it was needed and any of PSTAT_TASK_BASIC or PSTAT_THREAD_BASIC could be fetched. * libps/ps.h (PSTAT_TIMES): New macro. * libps/spec.c (ps_get_usr_time): Indicate the getter needs PSTAT_TIMES instead of PSTAT_THREAD_BASIC. (ps_sys_time_getter): Likewise. (ps_tot_time_getter): Likewise.

2014-01-12libfshelp: fix the api of fshelp_set_active_translatorJustus Winter
To detect if an active translator goes away, we need to register for dead name notifications. Those notifications have to be sent to a port known to the ports library, as the ports library handles the dead name notifications. The most straight forward way is to use the port to the underlying node for that. To that end, a reference to the port_info struct is handed in and kept in the list of active translators. This commit also moves the registration of dead name notifications to libfshelp. * libfshelp/fshelp.h (fshelp_set_active_translator): Add port_info argument. * libfshelp/translator-list.c (struct translator): Add port_info pointer. (translator_ihash_cleanup): Dereference port_info object. (fshelp_set_active_translator): Register dead name notifications. * libdiskfs/file-set-trans.c (diskfs_S_file_set_translator): Update accordingly. * libnetfs/file-set-translator.c (netfs_S_file_set_translator): Likewise.
2014-01-12trans/mtab: do not include non-filesystem translators by defaultJustus Winter
Traditionally, /proc/mounts includes only filesystem mount points. Previously though, the mtab translator included any kind of translator, like all /hurd/storeio translators. This causes problems with umount --all as this would remove the passive translator records from nodes in /dev. Fix this by only listing filesystem-like translators by default. Filesystem-like translators are identified by their response to dir_readdir messages sent to their root node. * trans/mtab.c (all_translators): New variable. (options): Add flag to preserve the old behavior. (parse_opt): Handle the new flag. (is_filesystem_translator): New function. (mtab_populate): Skip non-filesystem translators by default.
2014-01-12trans/mtab: make the translator multithreadedJustus Winter
* trans/mtab.c (main): Use ports_manage_port_operations_multithread.
2014-01-12trans/mtab: properly lock mtab objectsJustus Winter
* trans/mtab.c (struct mtab): Add lock. (open_hook): Initialize lock. (close_hook): Destroy lock. (trivfs_S_io_read): Lock mtab object, adjust error handling accordingly. (trivfs_S_io_seek): Likewise. (trivfs_S_io_readable): Likewise.
2014-01-12trans/mtab: remove the loop detection logicJustus Winter
Previously the mtab detector tried to detect whether it talks to itself by comparing the control port of the translator it currently visits with its own. This was done to prevent deadlocks. However, this did not detect non-trivial loops, i.e. two mtab translators would still dead-lock each other. Now that it is safe to actually file_name_lookup the root node of a mtab translator without triggering the generation of content, this logic can just be omitted. * trans/mtab.c (mtab_populate): Remove the loop detection logic.
