This was used to return a pre-locked UDPSocket in one place, but there
was really no need for that mechanism in the first place since the
caller ends up locking the socket anyway.
I encountered a WindowServer crash due to null-pointer dereference in
this function, so let's protect against it by simply skipping over
nulled-out WeakPtrs.
I added a FIXME about how we ideally wouldn't be in this situation in
the first place, but that will require some more investigation.
This call caused GCC 12's static analyzer to think that we perform an
out-of-bounds write to the v_key Vector. This is obviously incorrect,
and comes from the fact that GCC doesn't properly track whether we use
the inline storage, or the Vector is allocated on the heap.
While searching for a workaround, Sam pointed out that this call is
redundant as `Vector::resize()` already zeroes out the elements, so we
can completely remove it.

The function to protect ksyms after initialization, is only used during
boot of the system, so it can be UNMAP_AFTER_INIT as well.
This requires we switch the order of the init sequence, so we now call
`MM.protect_ksyms_after_init()` before `MM.unmap_text_after_init()`.
This is a raffinement of 49cbd4dcca.
Previously, the container was scanned to compute the size in the unhappy
path. Now, using `all_of` happy and unhappy path should be fast.
The following features are now available in the system, making these
patches unnecessary:
- isblank() function
- SIGSTKSZ constant
- MS_SYNC and MS_ASYNC msync() flags
- EDQUOT errno constant
The addition of the siginfo() function to LibC caused this port to
enable its stack overflow detection feature which, however, depends on
more features that we don't have.
These are aliases to `setjmp()` and `longjmp()` on our system,
as our implementations don't modify the signal mask.
This is required for the syzkaller executor process.
Unfortunately, most of the users are inside constructors, (and two
others are inside callback lambdas) so the error can't propagate, but
that can be improved later.
This adds a method `info()` to SoftGPU that returns the name of the
hardware vendor and device name, as well as the number of texture untis.
LibGL uses the returned texture unit count to initialize its internal
texture unit array.
Replaces the GLenum used in RasterizerConfig to select the draw buffer
with a simple boolean that disabled color output when the draw buffer
is set to GL_NONE on the OpenGL side.
