* proc: Fix WIFCONTINUEDSamuel Thibault2020-12-281-0/+1
| | | | * proc/wait.c (S_proc_mark_cont): Set p_status to __W_CONTINUED.
* proc: support waitid(WNOWAIT)Samuel Thibault2020-12-281-3/+9
| | | | | * proc/wait.c (S_proc_waitid): When options contains WNOWAIT, do not set p_waited or complete child death.
* Bump interface versionSamuel Thibault2020-12-281-1/+1
| | | | * hurd/version.h (HURD_INTERFACE_VERSION): Bump to 20201227.
* Add proc_waitidSamuel Thibault2020-12-275-11/+67
| | | | | | | | | | | | | | | | | | | proc_wait assumes that the caller always wants WEXITED, but waitid() does not. The new proc_waitid RPC requires the caller to specify at least one of WEXITED, WSTOPPED, or WCONTINUED. * hurd/process.defs (proc_waitid): New RPC. * hurd/process_reply.defs (proc_waitid): New RPC. * hurd/process_request.defs (proc_waitid): New RPC. * proc/proc.h (struct proc): Add p_continued field. * proc/wait.c (WCONTINUED, WEXITED): Define if not already defined. (S_proc_wait): Rename implementation to S_proc_waitid, and modify to stop assuming WEXITED. Add support for WCONTINUED. (S_proc_wait): Reimplement by just calling S_proc_waitid with an additional WEXITED. (proc_mark_stop): Clear p_continued. (proc_mark_cont): Set p_continued, clear p_waited, wake any waiting parent.
* proc: Also send SIGCHLD on child restartSamuel Thibault2020-12-271-0/+5
| | | | | * proc/wait.c (S_proc_mark_cont): When parent has not set nostopcld, send a SIGCHLD with CLD_CONTINUED.
* proc: send signals with POSIX sigcodesJeremie Koenig2020-12-274-6/+7
| | | | | | | | * proc/stubs.c (send_signal): Add a sigcode argument. * proc/proc.h (send_signal): Declare the sigcode argument. * proc/pgrp.c (leave_pgrp): Specify a null sigcode. * proc/wait.c (alert_parent): Use CLD_EXITED for SIGCHLD on exit. (S_proc_mark_stop): Use CLD_STOPPED for SIGCHLD on stop.
* Drop spurious changeSamuel Thibault2020-12-011-1/+0

* hurd_types: Add const_string_t typeSamuel Thibault2020-11-302-0/+2
| | | | | | | | This will allow to relieve constraints in callers, e.g. dir_lookup("") would otherwise produce a warning with gcc-11 since char[1024] would mean that dir_lookup would read all 1024 characters while it is not. * hurd/hurd_types.h (const_string_t): New type.
* MAKEDEV: make /dev/cd* go through rumpdiskSamuel Thibault2020-11-271-1/+1
| | | | * sutils/MAKEDEV.sh (cd*): Set MASTER to @/dev/disk:.
* libdiskfs: do not reuse pathbufSamuel Thibault2020-11-271-6/+2
| | | | | | | | | When deadling with multiple levels of symlinks, we really need double buffering between the current path and the symlink target, and thus cannot reuse pathbuf. * libdiskfs/dir-lookup.c (diskfs_S_dir_lookup): Always use alloca for pathbuf.
* rumpdisk: implement BLKRRPARTSamuel Thibault2020-11-261-2/+18
| | | | | | | | | | This is used by parted to reload the partition table. Since we do not actually implement partition tables, we can just ignore it. * rumpdisk/block-rump.c (BLKRRPART): New macro. (rumpdisk_device_set_status): New function. (rump_block_emulation_ops): Set device_set_status field to rumpdisk_device_set_status.
* storeio: Translate short reads to EIOSamuel Thibault2020-11-261-0/+8
| | | | | * storeio/dev.c (dev_buf_fill): When store returns less bytes than the block size, assume an EIO.
* libps: support getting RPC names for WAIT outputSamuel Thibault2020-11-235-24/+51
| | | | | | | | | | | * libps/Makefile (SRCS): Add ../utils/msgids.c. (../utils/msgids-CPPFLAGS): Add DATADIR macro. * libps/spec.c: Include "../utils/msgids.h". (get_rpc_name): Implement with msgid_info. * utils/msgids.c (parse_opt): Move end code to ... (msgids_scan_std): ... new function. * utils/msgids.h (msgids_scan_std): New prototype. * utils/ps.c (main): Call msgids_scan_std.
* libshouldbeinlibc: Fix printing truncated backtraceSamuel Thibault2020-11-221-2/+5
| | | | | * libshouldbeinlibc/assert-backtrace.c (__assert_fail_base_backtrace): If returned backtrace is smaller than skip we cannot print anything.

* libfshelp: Fix extern inline definitionsRomain Naour2020-11-213-3/+7
| | | | | | | | | | | | | | | | | | | | The commit [1] updated rlock.h and fshelp.h to use FSHELP_DEFINE_EXTERN_INLINE but it's never defined because FSHELP_EXTERN_INLINE is used in libfshelp/extern-inline.c. Update this file to use define FSHELP_DEFINE_EXTERN_INLINE.

* console-client: Fix listing nodesSamuel Thibault2020-11-181-4/+14
| | | | | | | | * console-client/trans.c (netfs_get_dirents): Fix counting the start node. Return 0 when there are no entries left, instead of trying to mmap zero bytes. (console_create_consnode): Set inode number, other entries get ignored by glibc's readdir().
* rumpdisk: automatically prepend /dev/Samuel Thibault2020-11-161-12/+9
| | | | | | | to keep coherent with other storeio translators, grub scripts, etc. * rumpdisk/block-rump.c (translate_name): Prepend /dev/ to disk name. (is_disk_device): Do not match heading /dev/.
* rumpdisk: auto-disable when kernel runs disk driversSamuel Thibault2020-11-151-28/+65

* libmachdev: Fix missing backtranslation to port nameSamuel Thibault2020-11-151-0/+1
| | | | | | | | | trivfs happens to set the payload for our control port, and we are not using payload translation for mach_i386, so we need to tell mig how to get back to the port name. * libmachdev/Makefile (mach_i386-MIGSFLAGS): Set -DMACH_PAYLOAD_TO_PORT=ports_payload_get_name.
* MAKEDEV: Set up rump translator and fix netdde translatorSamuel Thibault2020-11-151-2/+8
| | | | | | | * sutils/MAKEDEV.sh (rumpdisk): Set up /dev/rumpdisk and /dev/disk that points to it. (netdde): Point /dev/net to /dev/netdde. (eth*): Use /dev/net instead of /dev/netdde.
* MAKEDEV: Add master and rumpdisk supportSamuel Thibault2020-11-151-5/+17
| | | | | * sutils/MAKEDEV.sh: Add -M option to set the master device node. Add support for wd* devices through rumpdisk.
* MAKEDEV: use bashSamuel Thibault2020-11-141-1/+1
| | | | | | dash's expandarg always calls expandmeta which calls glob64, which stats the parameters. This is dangerous for MAKEDEV since it triggers the translator, which may be strictly unwanted when filling an installed system.

| | | | | | | | | | * rumpdisk/block-rump.c (struct block_data): Make taken field an integer instead of a boolean. (device_open): When search_bd succeeds, set a new reference and return a new port right. Separate out io_return_t err, int fd, and int ret to avoid confusions. Simplify the error handling path. (device_close): Decrement reference and close rump disk only when reaching zero. Also destroy our port.
* libmachdev: Avoid conflating translator name and pathSamuel Thibault2020-11-143-5/+6
| | | | | | | | | | | | bootstrap translators may not wish to appear in the FS, and the name of the translator does not have to match the path where it is getting installed. * libmachdev/machdev.h (machdev_trivfs_init): Add path parameter. * libmachdev/trivfs_server.c (machdev_trivfs_init): Add path parameter, set devnode only if it is not NULL.
