* Simplify deallocations.Justus Winter2017-08-0511-39/+20
| | | | | | | | | | | | | | | | | | | | | | | | free (NULL) is a nop, therefore it is not necessary to check that first. Simplify the code accordingly. This commit is the result of the following semantic patch: @@ identifier X; @@ -if (X) free (X); +free (X); * console-client/console.c: Simplify accordingly. * console-client/driver.c: Likewise. * console-client/vga.c: Likewise. * ftpfs/dir.c: Likewise. * libftpconn/unix.c: Likewise. * libps/fmt.c: Likewise. * libps/proclist.c: Likewise. * libstore/mvol.c: Likewise. * nfs/ops.c: Likewise. * proc/host.c: Likewise. * sutils/fstab.c: Likewise.
* Use our own variant of 'assert' and 'assert_perror'.Justus Winter2017-08-05229-865/+872
| | | | | Our variants print stack traces on failures. This will make locating errors much easier.

| | | | | | | * console-client/Makefile (install): Prepend $(prefix) to install target. * console-client/Makefile ($(XKB_BASE)/%): Rename target to $(prefix)$(XKB_BASE)/%.
* trans: Fix parallel build race around MIG-generated headersDavid Michael2017-06-101-0/+1
| | | | | | | This causes random.d to be generated which makes random.o depend on mach_debug_U.h, ensuring it exists before random.c is compiled. * trans/Makefile: Add random.c to SRCS when gcrypt is used.

| | | | | | | | | Fixes baf7e5c8ce176aead15c2559952d8bdf0da41ffd. * hurd/process.defs (proc_getmsgport): Make 'msgport' parameter polymorphic only on the sender side. (proc_task2proc): Likewise for 'proc'. (proc_pid2proc): Likewise.
* trans: Conditionally build the random translator.Justus Winter2017-06-045-4/+166
| | | | | | | | | | | | Only build the random translator if we find a suitable version of libgcrypt. This helps to reduce the build dependencies to bootstrap the Hurd. * aclocal.m4: Include 'libgcrypt.m4'. * config.make.in (HAVE_LIBGCRYPT): New variable. * configure.ac: Check for a suitable libgcrypt. * m4/libgcrypt.m4: New file. * trans/Makefile: Conditionally build the random translator.
* trans: New random translator.Justus Winter2017-06-0314-1922/+303
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.
* procfs: Remove superfluous calls.Justus Winter2017-06-031-8/+0
| | | | | * procfs/rootdir.c (rootdir_gc_vmstat): Remove superfluous 'host_info' calls.
* ext2fs: Reduce verbosity of missing xattr support on the FSSamuel Thibault2017-05-071-2/+2
| | | | | * ext2fs/xattr.c (ext2_list_xattr, ext2_get_xattr): Only warn about missing ext2fs support in debugging mode.
* eth-multiplexer: Fix iohelp missing dependency.Manolis Ragkousis2017-04-081-1/+1
| | | | * eth-multiplexer/Makefile (HURDLIBS): Add iohelp.
* Pass the kernel's task port to proc.Justus Winter2017-03-126-27/+166
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Previously, the early server bootstrap relied upon a specific task layout to determine the kernels task port. Explicitly pass it from the kernel instead. * boot/boot.c (default_boot_script): Add '--kernel-task' parameter to ext2fs. (main): New bootscript variable 'kernel-task'. * libdiskfs/boot-start.c (diskfs_kernel_task): Declaration variable. (diskfs_start_bootstrap): If '--kernel-task' was given to us, pass it along to startup. * libdiskfs/opts-std-startup.c (diskfs_kernel_task): New variable. (startup_options): Add '--kernel-task' option. (parse_startup_opt): Handle option. * proc/main.c (kernel_task): New variable. (OPT_KERNEL_TASK): New macro. (options): New variable. (parse_opt): New function. (main): Parse options. Use 'kernel_task' if provided. * release/servers.boot: Add '--kernel-task' parameter to ext2fs. * startup/startup.c (OPT_KERNEL_TASK): New macro. (options): Add '--kernel-task' option. (kernel_task): New variable. (insert_ports_fnc_t): New declaration. (run): Add argument for a function that inserts rights into the newly created task and adds arguments to the argument vector. (argz_task_insert_right): New function. (proc_insert_ports): Likewise. (parse_opt): New function. (main): Pass the kernel's task port to proc. (frob_kernel_process): Use the kernel's task port.
* startup: Simplify reference handling.Justus Winter2017-03-121-9/+3
| | | | | | * startup/startup.c (launch_core_servers): Instead of copying a send right and then deallocating it, move it. (init_stdarrays): Likewise.
* proc: Hierarchical proc servers.Justus Winter2017-03-117-2/+458
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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. (S_proc_pid2proc): Likewise. (S_proc_getprocargs): Likewise. (S_proc_getprocenv): Likewise. (S_proc_getprocinfo): Likewise. Translate PIDs. (S_proc_getloginid): Likewise. (S_proc_getloginpids): Likewise. * proc/mgt.c (namespace_is_subprocess): New function. (namespace_translate_pids): Likewise. * proc/msg.c (S_proc_getmsgport): Relay request for processes in a task namespace to the Subhurd's proc server. * proc/pgrp.c (S_proc_getsid): Likewise. Translate PIDs. (S_proc_getsessionpids): Likewise. (S_proc_getsessionpgids): Likewise. (S_proc_getpgrppids): Likewise. * proc/proc.h (namespace_is_subprocess): New prototype. (namespace_translate_pids): Likewise.
* hurd: Use polymorphic port types to return some rights.Justus Winter2017-03-104-10/+16
| | | | | | | | | | | | | | | | | | | | | Currently, the RPC definitions of two procedures of the process subsystem assume that the rights are created from a receive right. Similarly, 'proc_getmsgport' assumes that the right is to be copied. This needlessly limits the ability to relay the RPC in server code. This fixes this. The protocol is unchanged, only the generated server stubs assume an additional parameter for the type. * hurd/process.defs (proc_getmsgport): Make 'msgport' parameter polymorphic. (proc_task2proc): Make 'proc' parameter polymorphic. (proc_pid2proc): Likewise. * hurd/process_reply.defs (proc_getmsgport): Likewise. (proc_task2proc_reply): Likewise. (proc_pid2proc_reply): Likewise. * proc/info.c (S_proc_task2proc): Adapt server function. (S_proc_pid2proc): Likewise. * proc/msg.c (S_proc_getmsgport): Likewise.
* proc: Refactor.Justus Winter2017-03-092-8/+18
| | | | | | * proc/mgt.c (namespace_find_root): New function. (process_has_exited): Use new function. * proc/proc.h (namespace_find_root): New declaration.
* proc: Remove erroneous process entry.Justus Winter2017-03-091-0/+31
| | | | | | | | | | | | | Previously, there was a spurious copy of PID 1 in the process table, usually PID 8. PID 1, usually a sysvinit compatible process, needs to be PID 1 even though it is not actually the first process on the Hurd. To this end, PID 1 is reserved, and the task is later supplied to proc via proc_set_init_task once startup starts sysvinit. Fixes 8d16db0cc28b2d911aee918d5c3582ad29ddfeed. * proc/mgt.c (S_proc_set_init_task): Check if sysvinit's task already made it into the process table, and remove it if so.
* boot: Move declaration.Justus Winter2017-03-091-2/+4
| | | | | * boot/boot.c (new_task_notification): Move declaration to the top, add comment.
* proc: Receive new-task notifications on kernel's process port.Justus Winter2017-03-093-2/+14
| | | | | | | * proc/main.c (main): Initialize 'kernel_proc' and use it to register for new-task notifications. * proc/mgt.c (S_mach_notify_new_task): Adapt receiver check. * proc/proc.h (kernel_proc): New variable.
* proc: Open console earlier.Justus Winter2017-03-061-11/+28
| | | | | | | | This way, we can print diagnostics earlier. * proc/main.c (open_console): New function. (main): Call the new function as soon as we have the master device port.
* Avoid ports_interrupt_rpcs cancel itselfSamuel Thibault2017-03-041-2/+6
| | | | | | | | While this does not hurt immediately, callers of ports_interrupt_rpcs would themselves get canceled at the next cancelation point. * libports/interrupt-rpcs.c (ports_interrupt_rpcs): Do not call cancel ourself.
* boot: Make the halt message nicer.Justus Winter2017-03-031-1/+1
| | | | * boot/boot.c (S_host_reboot): Emit a carriage return.
* boot: Fix failing device lookups in unprivileged mode.Justus Winter2017-03-031-0/+3
| | | | | | | | | | | Previously, EMACH_SEND_INVALID_DEST was returned. This had devastating consequences on the translator linkage of storeio translators. When accessed, the parent translator tried to start the translator over and over again, spawning tasks until the system runs out of resources. * boot/boot.c (ds_device_open): Return the correct error when trying to open a non-existent device in unprivileged mode.
* boot: Add a verbose option.Justus Winter2017-02-283-2/+57
| | | | | | | | | | | | * boot/boot.c (verbose): New variable. (options): New option. (parse_opt): Handle new option. (ds_device_open): Be verbose if so desired. (task_died): Likewise. (S_mach_notify_new_task): Likewise. * boot/userland-boot.c (boot_script_task_create): Likewise. (boot_script_task_resume): Likewise. * boot/private.h: New file.
* boot: Cleanup Makefile.Justus Winter2017-02-281-2/+1
| | | | * boot/Makefile (SRCS): Drop removed sources.
* libshouldbeinlibc: Fix NDEBUG build.Justus Winter2017-02-281-1/+1
| | | | | * libshouldbeinlibc/assert-backtrace.h (assert_perror_backtrace): Fix variant for NDEBUG.
* Fix mig URLSamuel Thibault2017-02-141-3/+3
| | | | | | Thanks deathsbreed for the report. configure.ac: Fix mig URL
