* mach-defpager: comment on improving on lost dataSamuel Thibault2025-02-041-0/+5
| | | | Instead of killing the whole object.
* mach-defpager: also warn only once about read errorsSamuel Thibault2025-02-041-1/+7
|
* mach-defpager: Make it print warnings on out-of-swapSamuel Thibault2025-02-041-3/+35
| | | | To give explanation to processes suddenly crashing with SIGBUS.
* Add a description comment for the MIG type translation filesZhaoming Luo2024-12-141-1/+2

* More device_get_status count fixesSamuel Thibault2024-11-041-1/+1
|
* Fix line-buffered stderrSamuel Thibault2024-08-251-1/+1
| | | | | mach_open_devstream creates a fully-buffered stream by default. This prevents from seeing various messages.
* Only use host_get_kernel_version and default_pager_paging_storage_new in x86_64.Flavio Cruz2023-05-111-4/+6
| | | | | | | | | | Also fixed the implementation of default_pager_paging_storage_new in proxy def pager to call into default_pager_paging_storage_new. We can fast track the simplification of the RPC ABI for x86_64 if we don't have MACH_MSG_TYPE_STRING used in RPCs which forces msgt_size to use more than 8 bits.

* mach-defpager: Port to x86_64Sergey Bugaev2023-05-103-18/+18

* Use designated initializers when building mach_msg_type_tFlavio Cruz2023-05-041-8/+8
| | | | Message-Id: <ZFLcIs0iwiC9kQDf@jupiter.tail36e24.ts.net>
* Use uintptr_t for message payloads.Flavio Cruz2023-05-021-1/+1
| | | | | A follow up to 92fad38a043b75ed6b435b3efa574ede91dbe9ee in gnumach. Message-Id: <ZFCNasf9bJ9qj+CG@jupiter.tail36e24.ts.net>
* Use c_string for default_pager_filename_t to define a new ↵Flavio Cruz2023-04-251-0/+10
| | | | | | | | | | default_pager_paging_storage RPC. This brings us a bit closer to having all types' msgt_size representable with a single byte. We will be able to avoid mach_msg_type_long_t entirely for x86_64 since mach_msg_type_t can represent long types using a separate field. Message-Id: <ZEdO0Grm2AUw4Tfe@jupiter.tail36e24.ts.net>
* Remove default_pager_paging_file RPC from default pagerFlavio Cruz2023-04-153-80/+0
| | | | | | | | | The default_pager_paging_storage RPC has already it more than 20 years ago. Given that we want to change the type of default_pager_filename_t to use c_string, we can just remove the unused RPC. Tested that swapon/swapoff still work with the new binaries. Message-Id: <ZDoyNOE0XB77d5xj@mars.tail36e24.ts.net>
* Use long_integer_t for exception_raise RPCsFlavio Cruz2023-04-081-1/+1
| | | | | | | | Also update the crash_dump_task RPC since it gets the subcode from the signal details in Glibc. This should fix the existing build error. Message-Id: <ZDDrnHFHtiLIS53W@jupiter.tail36e24.ts.net>
* Further modernize Hurd code by enforcing strict prototypes and no implicit ↵Flavio Cruz2023-04-084-13/+13
| | | | | | | | | | | | | | | | | | function declarations. Most of the changes land in one of these buckets: * Removed unused declarations. * Used (void) to represent no parameters instead of () which means an undeterminate number of parameters. * Included missing header files whenever necessary (stdlib.h, sys/mman.h, etc) * Typedefed function pointers to be able to fully declare the parameter types. * Added declarations of library functions that are used elsewhere (example is libps/ps.h). * Made functions static whenever they are only used in that file. * Forwarded declarations of some methods that were made static. Message-Id: <ZDD1o7/tVYeZew+G@jupiter.tail36e24.ts.net>
* Modernize code by removing use of old style definitions.Flavio Cruz2023-04-033-232/+159
| | | | | Also add -Werror=old-style-definition to enforce new code. Message-Id: <ZBZ+8xf7GHy2RT/h@jupiter.tail36e24.ts.net>
* mach-defpager: Add defpager_server_nameSamuel Thibault2023-02-161-0/+2
| | | | To allow e.g. libubsan to detect it should be extra cautious.
* mach-defpager: Fix crash on pthread_cond_broadcastSamuel Thibault2023-02-161-3/+3
| | | | | We need to keep ds locked, otherwise it might disappear before we have a chance to broadcast the condition.
* Fix accessing bit 31Samuel Thibault2023-02-151-6/+6
| | | | | Shifting (signed) 1 to left 31 positions is undefined behavior. So make this an unsigned so it becomes defined behavior.
* Fix compiler warningSvante Signell2023-01-181-0/+1
|
* mach-defpager: Fix computing free spaceSamuel Thibault2023-01-011-5/+7
|
* mach-defpager: document lock orderingSamuel Thibault2022-12-311-0/+22
|
* mach-defpager: assert_backtrace() on panicSamuel Thibault2022-12-041-1/+2
| | | | | instead of just exiting: better print a backtrace so we get to know what happened.
* mach-defpager: Mark as essentialSamuel Thibault2022-12-031-0/+13
| | | | | So we get to know why the system gets stuck if mach-defpager happens to die.
* Fix types of read write and readables methodsEtienne Brateau2022-08-291-2/+2
| | | | Message-Id: <20220829193617.13481-1-etienne.brateau@gmail.com>
* Fix const warningsSamuel Thibault2022-01-173-7/+7
| | | | | Now that the RPCs have const, this forces us cleaning our const-meant functions.
* Make RPC input array parameters constSamuel Thibault2022-01-162-3/+3
| | | | | This follows mig's cf4bcc3f1435 ("Also add const qualifiers on server side")
* Fix build warningsSamuel Thibault2022-01-011-0/+3
| | | | No actual behavior change.
* wire_task_self: Use in various translatorsSamuel Thibault2021-12-303-81/+4
| | | | | | wire_task_self() was duplicating mach-defpager's wire_all_memory(), we can just make mach-defpager now use the former (and not mlockall either). Also pci-arbiter and rumpdisk can use it.
* mach-defpager: Fix error reportingSamuel Thibault2021-08-221-1/+1
| | | | * mach-defpager/main.c (main): After mlockall, report error from errno, not the value returned by mlockall.
* mach-defpager: Drop kalloc/kfreeSamuel Thibault2021-08-166-409/+65
| | | | | | | | | | | | glibc is removing its malloc hooks, but gnumach now has support for mlockall, which we can just use instead of kalloc/kfree. * mach-defpager/main.c (main): Call mlockall. * mach-defpager/kalloc.c: Remove. * mach-defpager/kalloc.h: Remove. * mach-defpager/default_pager.c: Use malloc/free instead of kalloc/kfree. * mach-defpager/setup.c: Likewise.
* mach-defpager: Fix warningSamuel Thibault2020-11-221-1/+1
| | | | * mach-defpager/default_pager.h (panic): Add noreturn function attribute.
* Remove remnants of cthreadsSamuel Thibault2020-11-111-5/+0
| | | | | | | | | | * doc/hurd.texi: Index pthread.h instead of cthreads.h * libports/Makefile (SRCS): Drop stubs.c. * libports/stubs.c: Remove file. * mach-defpager/default_pager.c (default_pager): Drop disabled cthreads calls. * pfinet/kmem_cache.c: Fix comment. * proc/stubs.c: Fix comments.
* Fix build with -fno-commonSamuel Thibault2020-03-312-2/+5

* mach-defpager: fix pager leakRichard Braun2016-12-261-12/+20
| | | | | | | | | | | | The server code for no-senders notifications wasn't updated to expect protected payloads. * mach-defpager/default_pager.c (default_pager_no_senders): Accept the pager structure directly instead of its port name and update body accordingly. (default_pager_no_senders): Accept protected payloads in addition to send-once rights and fetch the pager structure according to the message type.
* mach-defpager: make the default pager use vm_wire_allRichard Braun2016-12-244-59/+13
| | | | | | | | | | | | | | | The vm_wire_all call was recently added to GNU Mach so that the default pager doesn't depend on glibc malloc hooks any more. * mach-defpager/default_pager.c (start_default_pager_thread): Remove call to wire_memory. * mach-defpager/kalloc.c (kget_space): Likewise. * mach-defpager/wiring.c: Include mach/gnumach.h.
