This PR adds support for NtOpenSection, NtCreateSection, NtQuerySection, NtMapViewOfSection and NtUnmapViewOfSection.

Note LiteBox lacks shared anonymous backing, so a pagefile section is only allowed to be mapped once. For image section, it can be mapped multiple times by copying without copy-on-write mapping support.

Handle missing KnownDlls section opens
941d691
Implement NtOpenSection as a host-grounded resolve-and-reject path for the empty KnownDlls namespace. Reuse object-manager name resolution, zero the output handle on non-AV rejects, and let the Windows loader fall back to file-based mapping.

Document Windows section mapping limitations

Explain that LiteBox currently rejects simultaneous pagefile section views because PageManager lacks shared anonymous backing, and document the single-concurrent-view workaround that preserves unmap/remap contents via section-owned backing storage.

Validate pagefile section view protections

Reject NtMapViewOfSection pagefile views whose requested protection is incompatible with the section's create-time protection, matching host and ReactOS behavior. Allow compatible PAGE_NOACCESS and copy views while still requiring SECTION_MAP_READ for PAGE_NOACCESS.

Limit pagefile sections to one map
f8d624c
Remove the section-owned Vec backing and pagefile flush machinery to avoid guest-controlled kernel memory amplification. Pagefile sections now commit only guest view pages, reject concurrent and post-unmap remaps with STATUS_NOT_SUPPORTED, and keep map-failure rollback paths retryable.

Limit pagefile sections to one map
f8d624c
Remove the section-owned Vec backing and pagefile flush machinery to avoid guest-controlled kernel memory amplification. Pagefile sections now commit only guest view pages, reject concurrent and post-unmap remaps with STATUS_NOT_SUPPORTED, and keep map-failure rollback paths retryable.

Clarify pagefile section deferred-sharing rejects
7177b70
The Pagefile backing doc-comment now records that the second-concurrent-view
and remap-after-unmap rejects are one deferred capability (shared write-through
backing), not two unrelated limitations. Doc-only; no behavior change.

This PR adds support for NtOpenSection, NtCreateSection, NtQuerySection, NtMapViewOfSection and NtUnmapViewOfSection.
Note LiteBox lacks shared anonymous backing, so a pagefile section is only allowed to be mapped once. For image section, it can be mapped multiple times by copying without copy-on-write mapping support.

This PR adds support for NtOpenSection, NtCreateSection, NtQuerySection, NtMapViewOfSection and NtUnmapViewOfSection.
Note LiteBox lacks shared anonymous backing, so a pagefile section is only allowed to be mapped once. For image section, it can be mapped multiple times by copying without copy-on-write mapping support.

Handle missing KnownDlls section opens
941d691
Implement NtOpenSection as a host-grounded resolve-and-reject path for the empty KnownDlls namespace. Reuse object-manager name resolution, zero the output handle on non-AV rejects, and let the Windows loader fall back to file-based mapping.

Document Windows section mapping limitations
0f0aec6
Explain that LiteBox currently rejects simultaneous pagefile section views because PageManager lacks shared anonymous backing, and document the single-concurrent-view workaround that preserves unmap/remap contents via section-owned backing storage.

Remove redundant section mapping comment
6d5b9d9
Drop the NtMapViewOfSection comment that only restated the branch below without documenting a LiteBox-specific invariant or guest-visible behavior.

Move section mapping note into code
c7c46ca
Replace the standalone markdown note with a concise Rust doc comment on the pagefile section backing that explains the no-shared-mapping limitation and unmap/remap workaround.

Trim redundant section syscall comments
d866c71
Remove section.rs comments that only restated Wine/ReactOS branch structure and kept the comments that anchor host-observed status behavior or LiteBox-specific limitations.

@CvvT
Validate pagefile section view protections
77791ff
Reject NtMapViewOfSection pagefile views whose requested protection is incompatible with the section's create-time protection, matching host and ReactOS behavior. Allow compatible PAGE_NOACCESS and copy views while still requiring SECTION_MAP_READ for PAGE_NOACCESS.

@CvvT
Limit pagefile sections to one map
f8d624c
Remove the section-owned Vec backing and pagefile flush machinery to avoid guest-controlled kernel memory amplification. Pagefile sections now commit only guest view pages, reject concurrent and post-unmap remaps with STATUS_NOT_SUPPORTED, and keep map-failure rollback paths retryable.

Clarify pagefile section deferred-sharing rejects
7177b70
The Pagefile backing doc-comment now records that the second-concurrent-view
and remap-after-unmap rejects are one deferred capability (shared write-through
backing), not two unrelated limitations. Doc-only; no behavior change.
