IronClad v0.70

v0.7.0

Non-breaking changes

• Greatly improved block device (SATA, NVMe) caching. Leading to big performance improvements.
• Added a basic NVMe driver.
• Implement support for x86's SMAP, and expose it in an architecture-independent way.
• Harden syscall memory argument checks.
• Added AT_REMOVEDIR for the unlink syscall.
• Added a kernel-side terminal for easier early boot debugging for the
  x86_64-limine target.
• Improve PS2 device detection as to avoid false positives and false negatives.
• Reworked x86_64-limine's clock subsystem.
• Add support for pipe sockets with socketpair.
  Improved internal kernel printing by adding support for more 'Image uses.
• Better handle Out Of Memory (OOM) conditions with fallible allocations.
• Improve ACPI power button handling by exposing them to userland with the
  pwrbutton/sleepbutton devices, which can be polled by userland daemons
  for power commands.
• Expand program loading ASLR applications by also using it for dynamic
  program bases.
• Tons of bug fixes.
• Improve signal handling.

Breaking changes

• Removed the spawn syscall, modified the forksyscall` to take a
  FORK_VFORK argument that makes it not copy the parent process's tables. For
  the rationale, visit our blog's article on the matter.
• Removed power handling interfaces replaced by the pwrbutton/sleepbutton
  changes.
• Changed the mapping of the signal numbers handled by Ironclad due to POSIX
  requirements, affecting SIGHUP, SIGINT, SIGQUIT, SIGABRT, SIGKILL, SIGALRM,
  and `SIGTERM☠.
• Replaced the getrandom syscall for the POSIX-compliant getentropy.

Non-code related changes

• Moved our infrastructure from Savannah and Github to Codeberg.
• Coalesced project web presence to (https://ironclad-os.org).
• Started work on the project's blog, a
  hub for Ironclad news, articles, and all Ironclad, with RSS feeds for easy
  following.
