* Make RPC input array parameters constSamuel Thibault2022-01-161-1/+1
| | | | | This follows mig's cf4bcc3f1435 ("Also add const qualifiers on server side")
* random: export __trivfs_server_nameSamuel Thibault2022-01-011-0/+3
| | | | | 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.
* random: Do not require the latest gcrypt version, just use a version known ↵Samuel Thibault2018-11-181-1/+1

* Use our own variant of 'assert' and 'assert_perror'.Justus Winter2017-08-051-2/+2
| | | | | Our variants print stack traces on failures. This will make locating errors much easier.
* trans: New random translator.Justus Winter2017-06-031-0/+724
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.
