[PATCH 0/4] Fedora 42: Static Analysis and Compiler Warning Fixes

[Laurent Vivier <lvivier@redhat.com>]

This patch series addresses a collection of warnings and errors flagged
by GCC and Clang's static analyzer across various modules. The fixes
primarily involve clarifying code intent where warnings were false
positives or applying specific attributes to suppress warnings for
intentionally designed code constructs.

The series consists of the following patches (in order of application):

1.  **dhcpv6: fix GCC error (unterminated-string-initialization)**
    Silences GCC error for an intentionally non-NUL-terminated string.

2.  **virtio: Fix Clang warning (bugprone-sizeof-expression, cert-arr39-c)**
    Justifies intentional `sizeof` usage in pointer arithmetic against Clang warnings.

3.  **ndp: Fix Clang analyzer warning (clang-analyzer-security.PointerSub)**
    Clarifies pointer subtraction as a valid C idiom for struct offset calculation.

4.  **flow: fix clang error (clang-analyzer-security.PointerSub)**
    Confirms pointers in `flow_idx()` reference the same array, validating subtraction.
