Most of the changes land in one of these buckets: * Removed unused declarations. * Used (void) to represent no parameters instead of () which means an undeterminate number of parameters. * Included missing header files whenever necessary (stdlib.h, sys/mman.h, etc) * Typedefed function pointers to be able to fully declare the parameter types. * Added declarations of library functions that are used elsewhere (example is libps/ps.h). * Made functions static whenever they are only used in that file. * Forwarded declarations of some methods that were made static.

* Fix const warningsSamuel Thibault2022-01-174-5/+5
| | | | | Now that the RPCs have const, this forces us cleaning our const-meant functions.
* Make RPC input array parameters constSamuel Thibault2022-01-1615-35/+35
| | | | | This follows mig's cf4bcc3f1435 ("Also add const qualifiers on server side")

| | | | No actual behavior change.
* random: Add a trivfs_server_nameSamuel Thibault2021-12-302-1/+16
| | | | | | | glibc uses /dev/urandom for getrandom(), and from version 2.34 malloc initialization uses it. We need to be able to know whether we are running the random translator itself, in which case we can't read ourself.

* Traverse translator hierarchies using the fsys protocol.Justus Winter2017-09-124-48/+56
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Previously, we used the fs protocol to traverse the translator hierarchies. This, however, is conceptually flawed, because translators are bound to nodes, and a node can have zero or more links in the file system. Therefore, the previous method of returning a list of paths to the client and expecting them to be able to follow these to reach the child translators was always unreliable. Fix this by using the fsys protocol to traverse the hierarchy, and returning the control ports of all children. This is more robust, and also conceptually cleaner, because the fsys protocol is about translator linkage, hence this is the point to implement traversal. Also move the get source routine over. A per-node source really does not fit the reality of most translators, while a per-translator source makes sense in many cases. * hurd/fs.defs (file_get_children): Drop routine.

| | | | | | | | | | | | | | | | | | | | | So that static linking of e.g. console.static can work. * libdiskfs/io-stubs.c (diskfs_S_io_readsleep, diskfs_S_io_eofnotify, diskfs_S_io_postnotify, diskfs_S_io_readnotify): Mark weak. * libnetfs/fsstubs.c (netfs_S_file_notice_changes, netfs_S_file_getfh, netfs_S_ifsock_getsockaddr): Likewise. * libnetfs/fsysstubs.c (netfs_S_fsys_getfile: netfs_S_fsys_getpriv, netfs_S_fsys_init, netfs_S_fsys_forward, netfs_S_fsys_startup): Likewise. * libpager/stubs.c (_pager_S_memory_object_copy, _pager_S_memory_object_data_write, _pager_S_memory_object_supply_completed): Likewise. * libtrivfs/fsys-stubs.c (trivfs_S_fsys_startup, trivfs_S_fsys_getpriv, trivfs_S_fsys_init, trivfs_S_fsys_getfile): Likewise. * libtrivfs/io-stubs.c (trivfs_S_io_map_cntl, trivfs_S_io_get_conch, trivfs_S_io_release_conch, trivfs_S_io_eofnotify, trivfs_S_io_prenotify, trivfs_S_io_postnotify, trivfs_S_io_readsleep, trivfs_S_io_sigio, trivfs_S_io_readnotify): Likewise.

| | | | | | | | | | | | | | | | | Set 'is_root' if the node has been opened by the root user (this was the old behavior) or if it has been opened by the user the translator is executing under.

* Do not install libtrivfs mig stub headersSamuel Thibault2015-09-101-3/+0
