* exec: Properly preallocate address spaceSergey Bugaev2023-07-031-101/+67
| | | | | | | | | | | | | | | The existing code mapped the first PT_LOAD segment using anywhere=1, letting Mach pick an arbitrary location, and then uses anywhere=0 for all the remaining segments to place them next to the first one, as expected by the program. This, however, runs into many issues, primarily because of conflicts between interpreter and executable mappings. Some of those the existing code tried to work around. Instead, do it the way it's implemented in glibc: calculate upfront how much space the overall mapping will need, and ask Mach to preallocate this much address space. Then we deallocate it back, and instead map the program segments onto this very same place. Message-Id: <20230625231137.403096-4-bugaevc@gmail.com>
* exec: On 64-bit, map lower 4 GB inaccessible for PIEsSergey Bugaev2023-07-031-1/+14
| | | | | | | | | | We want to map the whole lower 4 GB of address space inaccessible to catch accidental pointer truncation. We can only do this when the executable (as well as the interpreter, if any) is compiled as PIC/PIE, since otherwise we would violate the ABI requirement. Fortunately most distributions have already switched to using PIE by default, so this should not be an issue. Message-Id: <20230625231137.403096-3-bugaevc@gmail.com>
* exec: Allow loading x86_64 executables on x86_64Sergey Bugaev2023-05-151-1/+7
| | | | | | | | | Since we don't support mixing i386 and x86_64 binaries on the same system (as running them requires different build-time gnumach configurations), the exec server can simply require the binary being loaded to have been built for the same architecture as the exec server itself.

* 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 Thibault2022-01-171-14/+16
| | | | | 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 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: fix setting the name of early serversJustus Winter2015-07-141-17/+33

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.

* exec: remove support for transparently ungziping executablesJustus Winter2013-09-151-138/+0
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Remove support for transparently ungziping executables from the exec server. The code in question makes the exec server unnecessarily complex and since the exec server is an essential process, crashing it makes /hurd/init crash the whole system. Since the gzip code is not thread-safe, all access to it is serialized, so there is a trivial way for one user to delay another users gzipped executables for some unspecified time. This can be accomplished by padding any program with easily compressed data, zipping it and executing it. Using such a program as an passive translator and then triggering its execution by the filesystem translator also stalls any requests to that filesystem (observed using the libdiskfs-based ext2fs). Since compressed executables cannot be mapped into the memory, they have to be uncompressed into allocated memory first. This is slower and any user with access to the exec server can make it allocate arbitrary amounts of memory. If the Hurd had proper memory accounting, this would probably be a way around it. So the compression support in exec seemingly creates various issues for little value, at least with the abundance of nonvolatile memory available today. * exec/Makefile: Remove gzip related files. * exec/exec.c: Remove anything #ifdef GZIPped. * exec/unzip.c: Move to libstore. * exec/crypt.h: Likewise. * exec/gzip.h: Likewise. * exec/inflate.c: Likewise. * exec/tailor.h: Likewise. * exec/util.c: Likewise. * libstore/Makefile: Remove the vpath magic for looking up the zip stuff.

| | | | | | | | | | | | | | | This commit removes the parts of the exec server that were once using the Binary File Descriptor library.

It may or may not work in its current state, so it is removed. If someone is interested, it can always be recovered from the version control system. * exec/exec.c: Remove all BFD related code. * exec/priv.h: Likewise. * TODO: Remove the corresponding item.

* fix common misspellingsJonathan Neuschäfer2011-08-201-1/+1
| | | | | | * Fix spelling with codespell[1] and manually review it. [1] http://git.profusion.mobi/cgit.cgi/lucas/codespell/
* Add comment about finish being called several timesSamuel Thibault2011-02-141-1/+3
|
* Protect exec from memory faultsSamuel Thibault2010-09-141-6/+16
| | | | | | | * exec/exec.c (load_section): Call i`hurd_safe_copyin' instead of `memcpy'. Handle error case. (check_gzip): Likewise. (check_bzip2): Likewise.
* Fix compressed binaries executionSamuel Thibault2010-09-141-4/+6
| | | | | | | | * exec/exec.c (check_gzip.zipread): Add `n' to `zipread_pos' to fix infinite loop. (check_bzip2.zipread): Likewise. (check_gzip): Set `file_data' and `file_size' fields after calling `finish' instead of before. (check_bzip2): Likewise.
* Fix in-memory mappingSamuel Thibault2010-09-141-2/+7
| | | | | | * exec/exec.c (map): When e->file_data is not NULL, return it plus `posn'. (prepare_in_memory): Call prepare_stream to clear stream positions.
* Fix duplicate oldtask port deallocationSamuel Thibault2009-12-211-2/+0
| | | | | | * exec/exec.c (do_exec): Do not deallocate oldtask when newtask != oldtask before the `out:' label since it is done again after it.
* Fixes long-standing random hang of exec.Samuel Thibault2009-08-231-2/+5
| | | | | * exec.c (finish): Set FILE_DATA and MAP_BUFFER members of E to NULL after freeing them.
* 2009-04-03 Samuel Thibault <samuel.thibault@ens-lyon.org>Samuel Thibault2009-04-021-3/+3
| | | | | * exec.c (prepare): Call PREPARE_STREAM earlier to permit calling finish_mapping on E even after errors, as is already done in do_exec.
* (check_elf_phdr): Fix typo in last change.Roland McGrath2004-10-231-1/+1
