* Fix *printf specifier for user space mach ports.Flavio Cruz2022-12-061-1/+1
| | | | | mach_port_t are mach_port_name_t and thus require %u instead of %lu. Message-Id: <Y42RELMbulK4xaKM@reue>
* Rename proc_complete_reauthentication to proc_reauthenticate_completeSamuel Thibault2022-08-101-1/+1
| | | | For coherency with the existing RPCs
* Make proc_reauthenticate () recreate proc portSergey Bugaev2022-08-101-0/+7
| | | | And add proc_complete_reauthentication ()
* exec: Use proc_reauthenticate_reassign ()Sergey Bugaev2022-08-101-42/+33
| | | | | This lets the exec server atomically replace the old task with the new task while raising its privileges.
* exec: Support ELIBEXEC errorSamuel Thibault2022-04-121-0/+7
| | | | | So users get a "Cannot exec a shared library directly" error message instead of a segfault.
* Fix const warningsSamuel Thibault2022-01-173-20/+22
| | | | | Now that the RPCs have const, this forces us cleaning our const-meant functions.
* Make RPC input array parameters constSamuel Thibault2022-01-161-18/+18
| | | | | This follows mig's cf4bcc3f1435 ("Also add const qualifiers on server side")
* Fix build warningsSamuel Thibault2022-01-011-2/+2
| | | | No actual behavior change.
* exec: only constraint loading the ELF interpreterSamuel Thibault2021-12-301-7/+7
| | | | | PIE programs do not need bitmask constraints, only the ELF interpreter needs to leave room for a non-PIE program.
* exec: Fix and use mask for memory layoutSamuel Thibault2021-08-161-20/+7
| | | | | | | Gnumach's 0650a4ee30e3 implements support for high bits being set in the mask parameter of vm_map. This allowed to remove the rmh kludge in the dynamic linker. Exec now can and should use the mask for excluding parts of the memory layout.

* Fix exec_paths through fakeroot or chrootJustus Winter2018-01-081-42/+51
| | | | | | | | | | | | | | | | | | | | | | If file_name_exec is not given, check_hashbang will try to locate the file. If argv[0] contains a '/', the file path is assumed to be absolute and it will try to open the file. Otherwise, the file is searched in the PATH. In either case, the resulting file identity port is compared to the identity port of the original file handle passed to check_hashbang. exec_paths_exec.patch explicitly provides the script files path in file_name_exec. According to the comment, if this path is provided, it is assumed to be the path to the script file and no attempt at locating the script file is done. However, the identity ports are still compared. This cannot succeed if fakeroot or chroot is used, because the process doing the exec and thus the initial file lookup is running in the chrooted environment, while the exec server is not. Fix this by skipping the identity test if file_name_exec is provided. * exec/hashexec.c (check_hashbang): Skip the file identity test if the file_name_exec is provided.

| | | | | | | | | or called with a small array. This notably happens when using a sub-exec, see BZ #48919. * exec/hashexec.c (check_hashbang): Check std_nports before accessing std_ports.
* Fix loading small pic programsSamuel Thibault2016-08-261-15/+42
| | | | | | | | | | | | | | | It happens that the link script for ld.so contains a hole, which might thus leave an empty page between the text and the data. When loading a small pic program, its text would then fit in there, and loading the data right after it would fail. We here rather force all pic loads to be mapped contiguously, starting from the place that was allocated for the first pic load. * exec/exec.c (load_section): Return the address of the end of the section. (load): Take the address to be used for loading pic objects as parameter, force pic objects there if it is not zero, and compute and return the address to be used for the next pic object. (do_exec): Pass addresses for pic loads between calls to load().

* exec: convert to trivfs dynamic classes and bucketsJustus Winter2015-09-271-19/+32
| | | | | | | | | | | | | | | | | libtrivfs contains two ways of managing more than one port class and bucket. There is the old way of using a statically allocated array with explicit length, and the new way with dynamically allocated vectors. Converting all users to the new way of handling multiple classes and/or buckets, we can simplify the code in libtrivfs. In many cases, the code will be simpler and more expressive for the user. This also fixes a mild bug. The classes and buckets given to `trivfs_startup' end up in the dynamic vectors too, making the object lookup code use the more complicated code path. * exec/main.c: Convert to dynamic classes and buckets.
* exec: add missing includeJustus Winter2015-09-231-0/+1

* exec: fix setting the name of early serversJustus Winter2015-07-141-17/+33
| | | | | | | | | | | | Previously, the exec server did not set the name of the servers started before the proc server. Instead this was done by the startup server, but this was merely a workaround, missing notably the startup server itself. * exec/exec.c (set_name): New function. (do_exec): Move the code setting the name to a new function, and also call it if the proc server is not started yet. * startup/startup.c (run): Drop hack.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | For reference, this patch was created using the following semantic patch, and then manually applying the change in all functions containing nested functions, as those are not supported by Coccinelle. @@ expression A, B; @@ - bzero (A, B) + memset (A, 0, B) * auth/auth.c: Replace `bzero' with `memset'. * boot/boot.c: Likewise. * defpager/defpager.c: Likewise. * exec/exec.c: Likewise. Also, drop `safe_bzero' and just use `hurd_safe_memset' directly. * ext2fs/ext2fs.c: Likewise. * ext2fs/getblk.c: Likewise. * ext2fs/pager.c: Likewise. * fatfs/pager.c: Likewise. * ftpfs/dir.c: Likewise. * ftpfs/netfs.c: Likewise. * isofs/inode.c: Likewise. * isofs/pager.c: Likewise. * libdiskfs/file-getfh.c: Likewise. * libdiskfs/file-statfs.c: Likewise. * libfshelp/fetch-root.c: Likewise. * libfshelp/start-translator.c: Likewise. * libftpconn/create.c: Likewise. * libftpconn/open.c: Likewise. * libftpconn/unix.c: Likewise. * libpipe/pipe.c: Likewise. * libps/procstat.c: Likewise. * libps/spec.c: Likewise. * libshouldbeinlibc/cacheq.c: Likewise. * libshouldbeinlibc/idvec.c: Likewise. * libshouldbeinlibc/ugids.c: Likewise. * libstore/argp.c: Likewise. * libstore/enc.c: Likewise. * libstore/kids.c: Likewise. * libthreads/alpha/thread.c: Likewise. * libtreefs/fsys.c: Likewise. * libtrivfs/file-statfs.c: Likewise. * mach-defpager/default_pager.c: Likewise. * pfinet/glue-include/asm/uaccess.h: Likewise. * pfinet/io-ops.c: Likewise. * pfinet/options.c: Likewise. * pfinet/socket.c: Likewise. * pfinet/timer-emul.c: Likewise. * pflocal/io.c: Likewise. * startup/startup.c: Likewise. * storeio/storeio.c: Likewise. * sutils/fstab.c: Likewise. * usermux/usermux.c: Likewise. * utils/fakeauth.c: Likewise. * utils/frobauth.c: Likewise. * utils/login.c: Likewise. * utils/x.c: Likewise.
* exec: add payload-aware intrans functionsJustus Winter2014-12-072-0/+9
| | | | | * exec/execmutations.h: Add mutators. * exec/mig-decls.h (begin_using_bootinfo_payload): New function.
* startup: bind the startup server to /servers/startupJustus Winter2014-11-211-2/+9
| | | | | | | | | | | | | | | | | | | | | | | | | Previously, the Hurd (ab)used the fact that the startup server speaks all protocols on its message port. Any server that wished to register for shutdown notifications would use proc_getmsgport to get a port to the startup server. This hardcodes the PID of /hurd/startup, and does not allow one to point a server to ones own startup server (e.g. using remap). Bind the startup server to /servers/startup instead. Use this to contact the startup server. * exec/main.c (S_exec_init): Use /servers/startup. Fall back to the old method so that the system still boots when the node /servers/startup is missing. * hurd/paths.h (_SERVERS_STARTUP): New macro. * libdiskfs/boot-start.c (diskfs_S_fsys_init): Use /servers/startup. * libdiskfs/init-startup.c (_diskfs_init_completed): Likewise. * pfinet/main.c (arrange_shutdown_notification): Likewise. * startup/Makefile (OBJS): Add fsysServer.o. * startup/startup.c (demuxer): Handle the fsys protocol. (main): Bind to /servers/startup. (S_fsys_getroot): Implement fsys_getroot. Stub out the rest.
* Fix actual procinfo_t typeSamuel Thibault2014-11-021-2/+2
| | | | | * exec/elfcore.c (dump_core): Use procinfo_t, which is already a pointer, instead of procinfo_t*.
* Fix proc_getprocinfo callsSamuel Thibault2014-11-021-2/+2
| | | | | | | | | | | The deallocation also needs to be fixed. Also, fetch_procinfo already took care of the conversion. * exec/elfcore.c (dump_core): Fix procinfoCnt taken from proc_getprocinfo. * utils/login.c (check_owned): Likewise. * libps/procstat.c (merge_procinfo): Remove conversion between bytes and int, already handled by fetch_procinfo.
* Fix proc_getprocinfo callsSamuel Thibault2014-11-021-1/+1
| | | | | | | | | The procinfoCnt argument is the number of elements of the procinfo_t array, not its size in bytes. * exec/elfcore.c (dump_core): Fix procinfoCnt given to proc_getprocinfo. * libps/procstat.c (merge_procinfo): Likewise. * utils/login.c (check_owned): Likewise.
* exec: redzone page zero before loading anythingJustus Winter2014-09-291-0/+10
| | | | | | This prevents load_section from mapping any sections to page zero. * exec/exec.c (do_exec): Redzone page zero before loading anything.
* exec: add proper argument parsing, add --device-master-portJustus Winter2014-09-291-13/+93
| | | | | | | | | | | | | | | | If the device master port is given, a boot-time exec server can print diagnostic messages earlier. * exec/main.c (opt_device_master): New variable. (OPT_DEVICE_MASTER_PORT): New macro. (options): New set of options. (parse_opt): New function. (trivfs_append_args): Likewise. (argp): Pull the argp definition out of main. (trivfs_runtime_argp): Set, so that we respond properly to fsysopts. (open_console): Pull the code out of S_exec_init and generalize it. (main): Call open_console if a device master port is given. (S_exec_init): Call open_console.
* exec: add missing includesJustus Winter2014-05-262-0/+2
| | | | | * exec/exec.c: Include mach/gnumach.h. * exec/main.c: Include device/device.h.
* exec: abbreviate the task name if necessaryJustus Winter2014-04-291-2/+13
| | | | | * exec/exec.c (do_exec): If the formatted task name exceeds TASK_NAME_SIZE, abbreviate it.
