    [$] Memory sealing for the GNU C Library

    Description:
    The mseal() system call allows a
    process to prevent any future changes to portions of its address space
    (thus "sealing" them); it was patterned after the mimmutable() system call in OpenBSD. mseal() generated a lot of discussion, but it was finally merged
    for the upcoming 6.10 kernel release. While mseal() was initially
    aimed at securing the Chrome browser, the hope was that it would be useful elsewhere; as a step toward realizing that hope, Adhemerval Zanella has
    posted a
    patch series adding support for and use of mseal() to the
    GNU C library (glibc).
