* Modernize code by removing use of old style definitions.Flavio Cruz2023-04-031-1/+1
| | | | | Also add -Werror=old-style-definition to enforce new code. Message-Id: <ZBZ+8xf7GHy2RT/h@jupiter.tail36e24.ts.net>
* trans: Drop spurious derefSamuel Thibault2023-01-011-4/+1
| | | | That was a remnant of manual port lookup.

* file_exec: Homogeneize adding the gratuitous send rightSamuel Thibault2022-08-231-7/+6

* Fix spurious EINTR while exec() within fakerootSamuel Thibault2022-08-231-0/+8
| | | | | | | | | | | | | | | | | | | | | | | The scenario is: - process running inside fakeroot exec()s - fakeroot forwards the exec call - exec starts thrashing the previous process, and notably close its ports - the send port that pointed to fakeroot is thus closed - fakeroot thus receives a no-senders notification - its libports thus interrupts the current RPC on it, i.e. the exec(), because it thinks that the caller is no more, but that was exactly the point of the exec()... - exec tries to interrupt its own RPCs, at best the execution will fail, at worse the process is already thrashed and there's nothing better than burying it for good. The symptom is processes running inside fakeroot seeming randomly crashing with SIGKILL. Making fakeroot keep a send right avoids the no-senders notification, thus the whole interruption (which was meaningless).
* mtab: turn part:x:device:y into /dev/ysxSamuel Thibault2022-02-251-1/+17
| | | | | This is needed when using a rumpdisk-based root disk. Otherwise fsck does not properly detect when it is mounted.
* Fix const warningsSamuel Thibault2022-01-174-17/+17
| | | | | Now that the RPCs have const, this forces us cleaning our const-meant functions.
* Make RPC input array parameters constSamuel Thibault2022-01-1613-50/+50
| | | | | This follows mig's cf4bcc3f1435 ("Also add const qualifiers on server side")
* Fix build warningsSamuel Thibault2022-01-015-9/+9
| | | | No actual behavior change.
* random: export __trivfs_server_nameSamuel Thibault2022-01-012-0/+4
| | | | | Making glibc access trivfs_server_name would violate namespace constraints, so we need to use a out-of-standard name.
* random: try opening time from gnumach before from /dev/timeSamuel Thibault2021-12-311-2/+2
| | | | | | | The system-wide random translator can access time from gnumach, while /dev/time comes from storeio, and its libc initialization (starting from glibc 2.34) uses /dev/random, which was thus bringing an initialization loop.
* random: Add a trivfs_server_nameSamuel Thibault2021-12-301-0/+2
| | | | | | | 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 Winter2017-09-122-139/+88
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Previously, the Hurd included a translator providing /dev/random and /dev/urandom based on a source copy of the random number generator found in classic GnuPG. The new random translator is using the SHAKE128 algorithm from the SHA-3 family as the underlying cryptographic primitive. Being a sponge construction, it allows the extraction of arbitrary amounts of pseudorandom data.

| | | | | | | | | | | | Previously, 'task', 'core_file', and 'ctty_id' were not deallocated if crash was configured to write core files, and 'ctty_id' was leaked if the crashing task was suspended.

Remove netfs_node_refcnt_lock. Add netfs_nref_light, netfs_nrele_light and handler netfs_try_dropping_softrefs. Adjust comments. * libnetfs/nput.c: Use refcounts_t. Call netfs_try_dropping_softrefs to remove any soft reference that the translator might have acquired during the lifetime of the node. Implement empty netfs_try_dropping_softrefs. * libnetfs/nref.c: Implement netfs_nref_light. * libnetfs/nrele.c: Use refcounts_t and netfs_try_dropping_softrefs. Implement netfs_nrele_light. * ftpfs/dir.c: Use netfs_nref without locking the old netfs_node_refcnt_lock. * ftpfs/node.c: Likewise. * usermux/mux.c: Use netfs_nref to increase hard references of the node. * hostmux/mux.c: Use netfs_nref to increase hard references of the node. * trans/fakeroot.c (new_node): Use a light reference when storing a node in the hash table. * trans/fakeroot.c (netfs_try_dropping_softrefs): Implement netfs_try_dropping_softrefs to remove the node from the hash table. * trans/fakeroot.c (netfs_node_norefs): Remove code to remove the node from the hash table. * trans/fakeroot.c (netfs_S_dir_lookup): Simplify lookup code since we don't need to lock netfs_node_refcnt_lock anymore. * procfs/netfs.c: Remove use of netfs_node_refcnt_lock. * nfs/cache.c: Add mutex to handle exclusive access to nodehash. This replaces the use of netfs_node_refcnt_lock. * nfs/cache.c (lookup_handle): Use nodehash_ihash_lock when accessing nodehash. Use netfs_nref_light to add one soft reference to the node just added to nodehash. * nfs/cache.c (netfs_node_norefs): Use netfs_nref. Don't use netfs_node_refcnt_lock and don't remove the node from nodehash here. * nfs/cache.c (netfs_try_dropping_softrefs): Drop the light reference when the node has no more hard references. * nfs/cache.c (recache_handle): Use nodehash_ihash_lock instead. * nfs/ops.c (netds_attempt_unlink): Use refcounts_references. * console/console.c (netfs_node_norefs): Use a soft reference to store a node in dir_node, cons_node, disp_node, inp_node. * console/console.c (netfs_try_dropping_softrefs): When dropping all soft references remove node pointer from the fields above.
* Add getting swap information from swapon and procfsSamuel Thibault2016-03-161-0/+13
| | | | | | | | | | | | | | | | | | | | | | | | * hurd/default_pager.defs (default_pager_storage_info): New RPC. * hurd/default_pager_reply.defs: Skip default_pager_storage_info RPC. * hurd/default_pager_types.h: Include <mach/machine/vm_types.h>. (vm_size_array_t): New type. * mach-defpager/priv.h (part): Add `name' field. * mach-defpager/default_pager.c (new_partition): Allocate and fill `part->name' field. Free it on error.

* Show firmlink mounts to mount pointsSamuel Thibault2016-03-151-13/+13
| | | | | * trans/mtab.c (mtab_populate): Always open the underlying node, and pass it to mtab_mark_as_seen instead of the translated node.
* Add get_source support to firmlinkSamuel Thibault2016-03-151-0/+8
