2014-08-31hurd: fix semantic of file_get_childrenJustus Winter
When first introduced as fsys_get_children, it made sense to return the list of children using paths relative to the root of the filesystem that was queried. Making the get_children method part of the fsys protocol was a mistake that has since been corrected in 9366d6b2. Instead of returning paths relative to the root of the translator, return paths relative to the path of the receiving node. This fixes a problem with the mtab translator. Previously, the mtab translator invoked on a target that was not the root directory of a translator would compute invalid paths, e.g.: /hurd/mtab: /any/path/servers/socket/26 No such file or directory * hurd/fs.defs (file_get_children): Update comment. * libfshelp/translator-list.c (fshelp_get_active_translators): Add argument PREFIX. Filter entries not beginning with PREFIX if non-NULL, and omit PREFIX from the returned paths. * libfshelp/fshelp.h (fshelp_get_active_translators): Update comment accordingly. Also clarify that both FILTER and PREFIX can be NULL. * libdiskfs/file-get-children.c (diskfs_S_file_get_children): Update comment, pass prefix to fshelp_get_active_translators. * libnetfs/file-get-children.c (netfs_S_file_get_children): Likewise.

* libnetfs/trans-callback.c (_netfs_translator_callback2_fn): Free user if creating the protid failed.
2014-05-28libnetfs: add netfs_make_node_alloc to allocate fat nodesJustus Winter
libnetfs has two kind of nodes, struct node and struct netnode. struct node is used to store libnetfs specific data, while struct netnode contains user supplied data. Previously, both objects were allocated separatly, and a pointer from the node to the netnode provided a mapping from the former to the latter. Provide a function netfs_make_node_alloc that allocates both nodes in a contiguous region. This reduces the memory allocation overhead when creating nodes. It also makes the relation between node and netnode a simple offset calculation. Provide two functions to compute the netnode address from the node address and vice-versa. Most notably, this makes implementing a cache on top of libnetfs easier. Auxiliary data for the cache can be stored in the user-defined netnode, and the fat node can be used as the value. * libnetfs/make-node.c (init_node): Move initialization here. (netfs_make_node): Use init_node. (netfs_make_node_alloc): New function to allocate fat nodes. * libnetfs/netfs.h (netfs_make_node_alloc): New declaration. (_netfs_sizeof_struct_node): Likewise.

2014-01-20libnetfs: include the mig-generated server headers in demuxer.cJustus Winter
GNU MIG recently gained support for emitting x_server_routine declarations in the generated server header file. Using this declaration, the x_server_routine functions can be inlined into the demuxer function. * libnetfs/demuxer.c: Include the mig-generated server headers.
2014-01-12libnetfs: register passive translator startupsJustus Winter
Detect passive translator startup and add the resulting active translator to the list of active translators. * libnetfs/dir-lookup.c (netfs_S_dir_lookup): Detect and register passive translator startup.
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.
2013-12-02libnetfs: improve the netfs_demuxer functionJustus Winter
Handle multiple request types as recommended by the Mach Server Writer's Guide section 4, subsection "Handling Multiple Request Types". This avoids initializing the reply message in every X_server function. The reply message has already been properly initialized in libports, so there is no need to call mig_reply_setup. * libnetfs/demuxer.c (netfs_demuxer): Improve the demuxer function.
2013-11-09Normalize whitespace at the end of each file to '\n'Justus Winter
Some files were not normalized. In console/motd.UTF8 the additional newline is intentional. Empty files were excluded as well.

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

2013-08-28libnetfs: properly respond to file_get_translator requestsJustus Winter
Properly respond to file_get_translator requests for nodes with a passive translator record. * libnetfs/file-get-translator.c (netfs_S_file_get_translator): Handle passive translator records.
2013-07-15libnetfs: fix consistency checkJustus Winter
passive is not a zero terminated string but a char * combined with a length. If passivelen == 0, passive may very well be not NULL, and dereferencing that pointer might not be safe. At the very least the consistency check is wrong. Fix that by checking passivelen instead of passive. * libnetfs/file-set-trans.c (netfs_S_file_set_translator): Fix sanity check.
2013-02-28Add io_select_timeout to the io interfaceRichard Braun
This change fixes a problem that can occur with non-blocking (and also blocking for very short times) select/poll calls. The problem occurs because the timeout is implemented at the client side. For a non-blocking call, this means that (depending on the code path taken in the C library) the client could get a timeout without a full RPC round-trip to the server. Moving the implementation of the timeout to the servers guarantees a full round-trip, and correct results for non-blocking calls. The modifications in this change depend on the availability of the recently added pthread_hurd_cond_timedwait_np function in libpthread. * boot/boot.c (io_select_common): New static function.
