* 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.

* trans: New random translator.Justus Winter2017-06-032-3/+730
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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. It is continuously fed entropy by hashing system state that is hard to predict. * Makefile (prog-subdirs): Remove 'random'. * NEWS: Update. * random/Makefile: Delete file. * random/TODO: Likewise. * random/gnupg-bithelp.h: Likewise. * random/gnupg-glue.h: Likewise. * random/gnupg-random.c: Likewise. * random/gnupg-random.h: Likewise. * random/gnupg-rmd.h: Likewise. * random/gnupg-rmd160.c: Likewise. * random/random.h: Likewise. * sutils/MAKEDEV.sh (random): Create node. (urandom): The new translator is both secure and non-blocking. Create a link from urandom to random for compatibility with Linux. * trans/Makefile (targets): Add 'random'. * trans/random.c: Move the skeleton of the old random translator here, but replace the PRNG with SHAKE128. Remove all dubious attempts of accounting for entropy. Do not block ever.

| | | | | | | | | | | | 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. This lead to resources not being released in the kernel, the filesystem, and the terminal subsystem, and could very well be responsible for making the Debian/Hurd shutdown hang. * trans/crash.c (S_crash_dump_task): Properly deallocate 'task', 'core_file', and 'ctty_id'.

I think only devnode should include it in mig-mutate.h. For term, only some stubs are including mig-mutate.h. For trans, there's no mig-mutate.h at all. Here's the modified patch.
* Add missing libraries to fix link errorsFlavio Cruz2015-12-301-12/+11
| | | | | | | | | | | | | | This fixes several linking problems I had in my recent cross-compilation of the Hurd. I added missing static libraries and also organized some of the targets for more concise rules. * console-client/Makefile: Add libiohelp.a and libihash.a. * daemons/Makefile: Add libihash.a and libshouldbeinlibc.a. * devnode/Makefile: Add iohelp and ihash to HURDLIBS. * random/Makefile: Likewise. * trans/Makefile: Reorder targets alphabetically and add libiohelp.a and libihash.a. * utils/Makefile: Add libihash.a.

* trans: improve demuxersJustus Winter2015-10-292-8/+21
| | | | | | | | | | | 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. * trans/proxy-defpager.c (proxy_defpager_demuxer): Improve the demuxer function. * trans/streamio.c (demuxer): Likewise.
