* Use our own variant of 'assert' and 'assert_perror'.Justus Winter2017-08-051-0/+3
| | | | | Our variants print stack traces on failures. This will make locating errors much easier.
* trans: New random translator.Justus Winter2017-06-031-0/+4
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.
* proc: Hierarchical proc servers.Justus Winter2017-03-111-0/+6
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Previously, a Subhurd's tasks were shown as weird processes in the Motherhurd. This change connects the proc server in the Motherhurd with the proc server in the Subhurd, embedding the Subhurd's process hierarchy. Subhurd's processes can now be inspected and debugged like any other process. * NEWS: Update. * boot/boot.c (mach_msg_forward): New function. (boot_demuxer): Forward messages arriving on the new task notification port from the proc server, and forward them to the proc server inside the Subhurd via the notification port. * proc/info.c (S_proc_task2proc): Relay request for processes in a task namespace to the Subhurd's proc server.

* boot: Allow unprivileged users to boot Subhurds.Justus Winter2016-11-011-0/+5
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Previously, boot handed privileged kernel ports to Subhurds. This made boot unusable for unprivileged users, and allowed Subhurds to wreak havoc on the whole system. Fix this by handing out pseudo ports instead of the privileged ports. * NEWS: Update. * boot/Makefile (MIGSTUBS): Build stubs for the new kernel interfaces. (MIGSFLAGS): Include mutation file. (HURDLIBS): Link against libihash. * boot/boot.c (privileged, want_privileged): New variables. (pseudo_privileged_host_port): New variable. (pseudo_pset, pseudo_kernel): Likewise.

If not running privileged, allocate more pseudo ports to hand out in place of privileged kernel ports, create a task namespace, and a task that the Subhurd can frob instead of the real kernel task.
