memfile::hp: Added test for `Mask`"s `.raw()` (`MAP_HHUGE_` flag generation.)
3 years ago
Avril c4f73ccfa0
memfile::hp: `find_size_bytes()` fixed and tested; should change function to return `eyre::Result<usize>` instead of `Option<usize>` considering how many different failure-paths exist.

memfile::hp: Added `Mask`: Converts bytes into a suitable `MAP_HUGE_` constant via its `.raw()` method, and a suitable flag for `memfd_create()` via its `.mask()` method.

Merge branch 'master' into safe-memfd: memfile: Merged `RawFile::try_link_from()`: Analogue to `try_link_to()`.

Avril c6032467fa
memfile: Added `RawFile::try_link_from()`: Analogue to `try_link_to()`. Instrumented and added panicking versions of both functions. Added `clone_from()` impl that uses `try_link_from()` (i.e. `dup2()`)

Started: `memfile::hp`: `MFD_HUGETLB` can be used when a size is known to exceed into the boundary of a hugepage. Currently in the process of writing function to collect all possible hugepage sizes and generate the correct flag masks for `memfd_create(, MFD_HUGETLB | ...)` for each one; and the smallest one that contains the known size can be used for the `memfd_create()` call (if the size fits any at all.)

Added TODOs for specific bugs (and impl related ideas for how to go about preventing/warning in the event of `mode-memfd` system OOM) ; moved some RawFd-related functions into a submodule

memfile: Disambiguated memfile errors resulting in `fallocate()` sizes being too large or the call itself failing.
