Quentin Perret 2620380106 Revert "vm-memory: mlock2(MLOCK_ONFAULT) guest memory for protected VMs" ... This reverts commit b975546c3f. Reason for revert: mlock is insufficient to prevent migration/compacting of guest memory, and therefore pKVM has been modified to perform pinning in the kernel, making the mlock call superfluous. Original change's description: > vm-memory: mlock2(MLOCK_ONFAULT) guest memory for protected VMs > > By default, the memory of a protected VM is inaccessible to the host > and crosvm. Consequently, attempts to access guest memory are fatal and > must be avoided in order for the guest to run. > > Mlock guest pages as they are faulted in for protected VMs, ensuring > that the host doesn't try to age or swap them out as a result of memory > pressure. > > Bug: b:204298056 > Test: cargo test on x86 and arm64 > Cc: Quentin Perret <qperret@google.com> > Cc: Andrew Walbran <qwandor@google.com> > Signed-off-by: Will Deacon <willdeacon@google.com> > Change-Id: I618ec1e8b1136a47a8b3ef563e45bc41d75ab517 > Reviewed-on: https://chromium-review.googlesource.com/c/chromiumos/platform/crosvm/+/3257689 > Tested-by: kokoro <noreply+kokoro@google.com> > Reviewed-by: Chirantan Ekbote <chirantan@chromium.org> Bug: b:204298056 Change-Id: Ibdcc579805c47adf35412b732829c074ce038471 Reviewed-on: https://chromium-review.googlesource.com/c/chromiumos/platform/crosvm/+/3310884 Tested-by: kokoro <noreply+kokoro@google.com> Commit-Queue: Quentin Perret <qperret@google.com> Auto-Submit: Quentin Perret <qperret@google.com> Reviewed-by: Will Deacon <willdeacon@google.com> Reviewed-by: Andrew Walbran <qwandor@google.com> Reviewed-by: Chirantan Ekbote <chirantan@chromium.org>		2021-12-02 11:28:53 +00:00
