Bananymous 31568fc5a1 Kernel: Rewrite Sockets to not be TmpInodes 
TmpInodes just caused issues because TmpFS kept them alive. There was
really no reason for sockets to even be stored inside a TmpFS...

Bananymous bce16cdd6e Kernel: Fix how socket closing works 
Sockets are now closed only when they are not referenced any more. This
allows child process to close socket and still keep it open for the
parent.

Bananymous 318ce5dec8 All: Fix a lot of compiler warnings from header files 
While reworking build system, header files started to report warnings.

Bananymous cad55a4da5 Kernel/LibC: Implement getsockname for ipv4 sockets 2024-06-17 20:54:45 +03:00
Bananymous ea7fc7f6c4 Kernel: Implement read-only FAT12/16/32 driver with long name support 
You can now mount FAT filesystems! This code might not work perfectly
but my quick testing seemed to work on all (FAT12/16/32) variants.

Bananymous 766439db6d Kernel: Start work on adding support for new filesystems 
Old code tried to create ext2 filesystem from all devices.

Bananymous 0af74fccda Kernel/LibC: Rework dirent structure 
dirent now contains statically sized d_name. This allows using
sizeof on the name and dirent properly, which some programs seem
to be using.

Bananymous 4d1f0e77f2 Kernel: Fix physical address size for x86_32 
Having 32 bit address space does not mean physical address space
is also only 32 bits...

Bananymous 99e30a4d7d Kernel: Replace i386 with i686 
I don't really want to be working with i386 since it doesn't support
compare exchange instruction
 2024-03-26 02:48:26 +02:00
Bananymous 2352c86048 Kernel: i386 has 14 indirect blocks in TmpInode instead of 2 
This allows keeping size of TmpInodeInfo as 128

Bananymous f73e954b28 Kernel: Remove SpinLock from Pipe 
Pipe already is using lock on the inode. If you read from pipe when
there was no data, pipe blocked indefinately since writes were blocked
by Inode::m_lock.

Bananymous 3fc1edede0 Kernel/LibC: Implement super basic select 
This does not really even block but it works... :D

Bananymous 2cee2a85e6 Kernel: DevFS now stores all devices 
This allows removing hack in PCI that was required to keep NVMe
controller alive.

Bananymous 12474addda Kernel: Make Inodes use the new lock

already has.

Bananymous 7a8fd6d04a Kernel: TmpFS doesn't mark any functions as final 
I didn't think these would be overloaded, but they are
 2023-11-21 15:19:34 +02:00
Bananymous b749963b62 Kernel: Add common {read,write}_blocks() api to BlockDevice 2023-11-21 15:19:07 +02:00
Bananymous cadb56d8ba Kernel: ProcFS inodes reflect processes ruid/rgid 
setgid/setuid did not change the permissions of procfs inodes. This
made Shell launched by init not appear in meminfo.

Bananymous d6ae1bcf36 Kernel: Remove now obsolete RamFS 
Everything is using now the better TmpFS which uses physical pages
for page allocation instead of the static kmalloc memory.

Bananymous 76f48f095c Kernel: Rewrite a lot of ext2 code 
This commit consists of multiple big changes

1. blocks for inodes are now allocated on demand
  - reading from non allocated block will just return zeroes
  - writing to non allocated block allocates it

2. code doesn't really use raw pointers anymore
  - all casts to uint32_t or structures are now replaced with
    spans. either as<T> or as_span<T> which both are bounds
	checked

3. code doesn't depend on random macros for accessing indirect blocks
  - i added some recursive functions which take care of this :)

Bananymous 35b46e37bb Kernel: Fix ext2 inode deletion cleanup 
I now cleanup all blocks (including direct) in i_block array

Bananymous 38c267b4c8 Kernel: Fix ext2 inode deletion 
fsck now reports clean filesystem even after deleting files
 2023-10-26 02:05:05 +03:00
Bananymous b7007016c0 BAN: Implement Ext2 file unlinking 
Ext2 inodes can now be unlinked from directories and after last
inode closes (destructor gets called) we check if link count is 0
and cleanup the inode from filesystem
