Clean up the Wasm spec tests CMake rules to extract and compile the wat
files into wasm files in the LibWasm binary directory instead of its
source directory. Also make the rules more robust to missing host tools,
and use more CMake install rules for the test files rather than relying
on build-root-filesystem.sh. Add some FIXMEs for later, we really
shouldn't be doing installation of test files into /home/anon at the
build-root-filesystem stage in $CURRENT_YEAR. Tests go in /usr/Tests
This fixes a few sizing issues too. The page size is now correct in most
cases! \o/
We get to remove some of the `to_type<>()` shenanigans, though it
reappears in some other places.
Store the ratio between device and CSS pixels on the PaintContext, so
that it can convert between the two.

This patch adds the `find_executable()` function that will hopefully
find executables in a distro-agnostic way and that is (hopefully as
well) easily upgradable.
The function uses some bash functionalities. So, we now require bash
for each script that includes `.shell_include.sh`.
We return early from the DateTimeFormat constructor to avoid crashing on
assertions when the CLDR is disabled. However, after commit 019211b, the
spec now mandates we assert the time zone identifier is valid. The early
return resulted in this identifier being an empty string.
This now allows you to select a background color for your new image,
and optionally allows saving that default. You can pick between
Transparent, White, Black, or a custom color (similar to other
editors).
This now only requires `size + alignment` bytes while searching for a
free memory location. For the actual allocation, the memory area is
properly trimmed to the required alignment.
This keeps us from tripping strict aliasing, which previously made TCP
connections inoperable when building without `-fsanitize=undefined` or
`-fno-strict-aliasing`.
This patch validates that the size of the auxiliary vector does not
exceed `Process::max_auxiliary_size`. The auxiliary vector is a range
of memory in userspace stack where the kernel can pass information to
the process that will be created via `Process:do_exec`.
The reason the kernel needs to validate its size is that the about to
be created process needs to have remaining space on the stack.
Previously only `argv` and `envp` were taken into account for the
size validation, with this patch, the size of `auxv` is also
checked. All three elements contain values that a user (or an
attacker) can specify.
This patch adds the constant `Process::max_auxiliary_size` which is
defined to be one eight of the user-space stack size. This is the
approach taken by `Process:max_arguments_size` and
`Process::max_environment_size` which are used to check the sizes
of `argv` and `envp`.
We previously depended on sudo's specific -E flag to keep all the
environment variables when performing a privilege escalation. We now
incorporate the -E flag into the $SUDO variable, allowing for other
privilege escalation binaries (such as doas) to be used (as long as
they preserve the current environment variables).
