2021-08-09memory_object_proxy: Deliver no-sender notifications on a separate portv1.8+git202108091.8+git20210809Samuel Thibault
Otherwise userland can send spurious notifications.
2021-08-09memory_object_proxy: Explicit that creation wants a send rightSamuel Thibault
This is required anyway, and allows the caller to pass on MAKE_SEND.
2021-08-09memory_object_proxy: Fix send port right leakSamuel Thibault
On success we'd have to clean the port right. Just consume it.
2021-08-09memory_object_proxy: Fix checking proxy lengthSamuel Thibault
We want to prevent subproxies from requesting larger sizes than what a proxy initially allowed.
2021-08-09Memory object proxy: add support for ranges and nestingJoan Lledó
2021-08-09memory_object_proxy: release resources on no-send notificationSamuel Thibault
2021-06-06vm_map: Allow exagerated max_prot for nowSamuel Thibault
glibc's mmap implementation assumes that gnumach will cap the prot for it, so for now let's revert back to capping rather than rejecting. That fixes mmap(SHARED|READ) for read-only objects.
2021-05-24Revert "vm_map: Allow passing the name of a memory object"Samuel Thibault
This reverts commit af9f471b500bcd0c1023259c7577e074fe6d3ee5.
2021-05-24vm_map: Fix proxy object protection checkSergey Bugaev
* If not making a copy, don't cap protection to the limit enforced by the proxy, and only require read access. This fixes mapping parts of read-only files MAP_ANON + PROT_READ|PROT_WRITE. * Instead of silently capping protection, return KERN_PROTECTION_FAILURE to the caller like the other vm_*() routines do.
2021-04-05rtc: Add read/write messagesSamuel Thibault
We are still having issues with bogus dates. This adds prints at boot and time set, to make sure what we actually read and write. * i386/i386at/rtc.c: Include <kern/printf.h> (readtodc): Warning about reaching CENTURY_START. Print the time read from RTC. (writetodc): Record in RTC remainder of division of year by 100 rather than subtracting 1900. Print the time written to RTC.
2021-04-05kd: Do not read the CMOS ramSamuel Thibault
This could conflict with read/writing the RTC. * i386/i386at/kd.c (kd_xga_init): Do not read the CRAM. We were always assuming VGA anyway.
2021-04-05apic: Also unmask irq 3 and 4 earlySamuel Thibault
We unmasked by hand kd's irq 1, but com0/1 also need unmasking. More generally we should unmask irqs as appropriate. * i386/i386at/model_dep.c (machine_init): Unmask irq 3 and 4.

2021-04-05thread_info: Fix crash when requesting for thread that never ranSamuel Thibault
* kern/thread.c (thread_info): Set last_processor to 0 when the thread never ran.
2021-04-05thread_info: Fix returning last_processorSamuel Thibault
thread->last_processor is a processor_t, not a slot number. * kern/thread.c (thread_info): Set sched_info->last_processor to thread->last_processor->slot_num rather than thread->last_processor.
