2025-02-09Restring default_pager_paging_storage to i386Samuel Thibault
Newer ports won't have it either.
2025-02-09mach-defpager: Move default_pager_exception_port declaration to headerSamuel Thibault
2025-02-08Add names to threadsSamuel Thibault
2025-02-04mach-defpager: comment on improving on lost dataSamuel Thibault
Instead of killing the whole object.
2025-02-04mach-defpager: also warn only once about read errorsSamuel Thibault
2025-02-04mach-defpager: Make it print warnings on out-of-swapSamuel Thibault
To give explanation to processes suddenly crashing with SIGBUS.

2024-11-04More device_get_status count fixesSamuel Thibault
2024-08-25Fix line-buffered stderrSamuel Thibault
mach_open_devstream creates a fully-buffered stream by default. This prevents from seeing various messages.
2023-05-11Only use host_get_kernel_version and default_pager_paging_storage_new in x86_64.Flavio Cruz
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.

2023-05-04Use designated initializers when building mach_msg_type_tFlavio Cruz
Message-Id: <ZFLcIs0iwiC9kQDf@jupiter.tail36e24.ts.net>
2023-05-02Use uintptr_t for message payloads.Flavio Cruz
A follow up to 92fad38a043b75ed6b435b3efa574ede91dbe9ee in gnumach. Message-Id: <ZFCNasf9bJ9qj+CG@jupiter.tail36e24.ts.net>
2023-04-25Use c_string for default_pager_filename_t to define a new ↵Flavio Cruz
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>
2023-04-15Remove default_pager_paging_file RPC from default pagerFlavio Cruz
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>
2023-04-08Use long_integer_t for exception_raise RPCsFlavio Cruz
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>
2023-04-08Further modernize Hurd code by enforcing strict prototypes and no implicit ↵Flavio Cruz
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>
2023-04-03Modernize code by removing use of old style definitions.Flavio Cruz
Also add -Werror=old-style-definition to enforce new code. Message-Id: <ZBZ+8xf7GHy2RT/h@jupiter.tail36e24.ts.net>
2023-02-16mach-defpager: Add defpager_server_namev0.9.git20230216Samuel Thibault
To allow e.g. libubsan to detect it should be extra cautious.
2023-02-16mach-defpager: Fix crash on pthread_cond_broadcastSamuel Thibault
We need to keep ds locked, otherwise it might disappear before we have a chance to broadcast the condition.
2023-02-15Fix accessing bit 31Samuel Thibault
Shifting (signed) 1 to left 31 positions is undefined behavior. So make this an unsigned so it becomes defined behavior.
2023-01-18Fix compiler warningSvante Signell
2023-01-01mach-defpager: Fix computing free spaceSamuel Thibault
2022-12-31mach-defpager: document lock orderingSamuel Thibault
2022-12-04mach-defpager: assert_backtrace() on panicSamuel Thibault
instead of just exiting: better print a backtrace so we get to know what happened.
2022-12-03mach-defpager: Mark as essentialSamuel Thibault
So we get to know why the system gets stuck if mach-defpager happens to die.
2022-08-29Fix types of read write and readables methodsEtienne Brateau
Message-Id: <20220829193617.13481-1-etienne.brateau@gmail.com>
2022-01-17Fix const warningsSamuel Thibault
Now that the RPCs have const, this forces us cleaning our const-meant functions.
2022-01-16Make RPC input array parameters constSamuel Thibault
This follows mig's cf4bcc3f1435 ("Also add const qualifiers on server side")
2022-01-01Fix build warningsSamuel Thibault
No actual behavior change.
2021-12-30wire_task_self: Use in various translatorsSamuel Thibault
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.
2021-08-22mach-defpager: Fix error reportingSamuel Thibault
* mach-defpager/main.c (main): After mlockall, report error from errno, not the value returned by mlockall.
2021-08-16mach-defpager: Drop kalloc/kfreeSamuel Thibault
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.
2020-11-22mach-defpager: Fix warningSamuel Thibault
* mach-defpager/default_pager.h (panic): Add noreturn function attribute.
2020-11-11Remove remnants of cthreadsSamuel Thibault
* 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.

2016-12-24mach-defpager: make the default pager use vm_wire_allRichard Braun
