* hurd: fix semantic of file_get_childrenJustus Winter2014-08-311-4/+5
| | | | | | | | | | | | | | | | | | | | | | | | | | | 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: add netfs_make_node_alloc to allocate fat nodesJustus Winter2014-05-283-6/+53
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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. (netfs_node_netnode): Compute netnode address from node address. (netfs_netnode_node): And vice-versa. * libnetfs/init-init.c (_netfs_sizeof_struct_node): New variable.

| | | | | | | | | | | | | | | | | | | | 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.

| | | | | | | * libdiskfs/peropen-make.c (diskfs_make_peropen): Move `strdup` before port reference modifications, to fix abortion. * libnetfs/make-peropen.c (netfs_make_peropen): Check for `malloc` failure. Move `strdup` before port reference modifications, to fix abortion.
* libnetfs: add fsys_get_sourceJustus Winter2013-09-154-3/+72
| | | | | | | | | | | Add a user overridable function netfs_get_source with a default implementation returning EOPNOTSUPP. Add a server function for fsys-get-source. * libnetfs/Makefile: Add fsys-get-source.c and get-source.c * libnetfs/netfs.h: Add netfs_get_source. * libnetfs/fsys-get-source.c: New file. * libnetfs/get-source.c: Likewise.
* libnetfs: add fsys_get_childrenJustus Winter2013-09-154-2/+131
| | | | | | | | | | | Keep track of active translators and handle fsys_get_children requests. * libnetfs/Makefile (FSYSSRCS): Add fsys-get-children.c. * libnetfs/dead-name.c (ports_dead_name): Remove dead translators. * libnetfs/file-set-translator.c (netfs_S_file_set_translator): Register active translators. * libnetfs/fsys-get-children.c: New file.
* libnetfs: track file name in struct peropenJustus Winter2013-09-155-2/+41
| | | | | | | | | | | Track the relative path used to obtain a file handle in the struct peropen. * libnetfs/netfs.h (struct peropen): New field path. * libnetfs/make-peropen.c (netfs_make_peropen): Initialize path. * libnetfs/release-peropen.c (netfs_release_peropen): Free path. * libnetfs/fsys-getroot.c (netfs_S_fsys_getroot): Initialize path. * libnetfs/dir-lookup.c (netfs_S_dir_lookup): Preserve the path.
* libnetfs: register libnetfs-based translators as importantJustus Winter2013-08-291-0/+14
| | | | | | | Register libnetfs-based translators running as root as important processes at the proc server. * libnetfs/init-startup.c (netfs_startup): Mark us as important.
* libnetfs: handle dead-name notificationsJustus Winter2013-08-292-1/+46
| | | | | | | | | 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.
* libnetfs: implement file_get_translator_cntlJustus Winter2013-08-293-9/+53
| | | | | | This is a trivially adapted version of libdiskfs/file-get-transcntl.c. * libnetfs/file-get-transcntl.c: New file.
* Optimize translator string copySamuel Thibault2013-08-281-1/+1
| | | | | * libnetfs/file-get-translator.c (netfs_S_file_get_translator): Call memcpy instead of memmove.
