Bananymous 0b05e9827b BAN: Use memmove instead of memcpy on overlapping data 
I was accidentally using memcpy where memmove was needed
 2024-10-13 22:00:16 +03:00
Bananymous 1c1a76d6d7 BAN: Member function pointers now use references instead of pointers 
This seems cleaner as class pointer cannot be null anymore
 2024-10-13 22:00:16 +03:00
Bananymous df4f37d68d BAN: only define placement new operators for banan-os targets 
This allows building and using BAN library outside of banan-os!

Bananymous 44629ba5dd BAN: Allow userspace to use string literals with BAN::Error 2024-10-10 21:54:52 +03:00
Bananymous 2da6776451 BAN: Update {Byte}Span API with better constness 
const BAN::Span<int> is now allowed to modify its underlying data, but
the container itself is const.

BAN::Span<const int> can be used for spans over constant data.

You can now have "chained" commands in alias

 2024-10-07 04:10:25 +03:00
Bananymous 1824988b9a Shell: Add support for simple aliases

a good start.

warning about.

Bananymous 2d11ce9669 Kernel: Fix interrupt system 
I had not understood how MSIs work and I was unnecessarily routing them
through IOAPIC. This is not necessary and should not be done :D

Also MSIs were reserving interrupts that IOAPIC was capable of
generating. Now IOAPIC and MSIs use different set of interrupts so
IOAPIC can use more interrupts if needed.

Bananymous b89fc3fe87 Kernel: Implement ANSI SGR 7 to invert colors 
This allows vim's visual selection to show up
 2024-09-26 15:08:11 +03:00
Bananymous 57ae74f908 Terminal: Implement more ANSI escape handling 
This patch adds L and M codes for inserting and deleting lines and SGR 7
for inverting colors
 2024-09-26 15:07:08 +03:00
Bananymous 1a6804b4b4 Terminal: Make Terminal::handle_csi() return invalidated rectangle 
When I updated Terminal to only do a single invalidation after all of
input text was printed, I forgot to change handle_csi

This allows exiting vim when using this function for key mappings :D
 2024-09-24 18:08:34 +03:00
Bananymous 4e9f39384a LibC: Initialize libc only once 
This was breaking stuff with dynamic loader initializing libc and main
executable reinitializing it later :D
 2024-09-24 17:56:12 +03:00
Bananymous 39802b56c1 Kernel: Allow SYS_EXEC to fail at any point 
This patch builds new executable image to another pml4 structure and
only after everything is validated will current context be replaced.
This allows exec to fail "late" where previously it would panic the
kernel or kill the process. This allows graceful handling of exec
failures in userspace!

Bananymous ebb87ccdde Kernel: Add asserts for overflow checks with ms -> ns conversions 2024-09-24 16:28:44 +03:00

Bananymous 348d04f7f5 Kernel: Implement static Process::kill() 
This allows killing processes even when there does not exist a current
thread.

Bananymous 1b0086217c Terminal: Do scrolling in putchar if necessary 
I overlooked that handling *newline* scrolls would be enough. You can
definitely scroll more if printing a lot of text which wraps to the next
line.
 2024-09-23 15:00:47 +03:00
Bananymous d395cf38b7 Kernel: Binding to port 0 will always find unused port 2024-09-22 17:30:01 +03:00

There was an kernel panic if stack trace contained uncanonical
addresses.
