Scenario Erasure of memory freed by killed userspace processes

Hooks

Before features/support/hooks.rb:269 0.003

Steps

Given I have started Tails from DVD without network and logged in 23.236

And I prepare Tails for memory erasure tests 0.586

When I start a process allocating 128 MiB of memory with a known pattern 3.745

Then patterns cover at least 128 MiB in the guest's memory 3.795

Output 1

Pattern coverage: 100.000% (128 MiB out of 128 MiB reference memory)

When I kill the allocating process 2.306

Then I find very few patterns in the guest's memory after 3 seconds 6.825

Output 1

Pattern coverage: 0.000% (0 MiB out of 907 MiB reference memory)

Output 1

Pattern coverage: 0.000% (0 MiB out of 891 MiB reference memory)

When I mount a 128 MiB tmpfs on "/mnt" and fill it with a known pattern 9.648

Then patterns cover at least 99% of the test FS size in the guest's memory 3.472

Then I find very few patterns in the guest's memory 3.895

Output 1

Pattern coverage: 0.000% (0 MiB out of 903 MiB reference memory)

# write cache

When I fill the USB drive with a known pattern 2.765

Then patterns cover at least 75% of the test FS size in the guest's memory 3.830

Output 1

Pattern coverage: 88.416% (112 MiB out of 127 MiB reference memory)

Then I find very few patterns in the guest's memory after 3 seconds 6.274

Output 1

Pattern coverage: 0.000% (0 MiB out of 903 MiB reference memory)

# read cache

When I mount the USB drive again 0.288

And I read the content of the test FS 0.523

Then patterns cover at least 99% of the test FS size in the guest's memory 3.581

Output 1

Pattern coverage: 100.596% (128 MiB out of 127 MiB reference memory)

When I umount the USB drive 0.672

Then I find very few patterns in the guest's memory after 3 seconds 6.088

Then I find very few patterns in the guest's memory 2.498

Output 1

Pattern coverage: 0.000% (0 MiB out of 896 MiB reference memory)

# write cache

When I fill the USB drive with a known pattern 3.073

Then patterns cover at least 99% of the test FS size in the guest's memory 2.648

Scenario Erasure of the overlayfs read-write branch on shutdown

Hooks

Before features/support/hooks.rb:269 0.003

Steps

Given I have started Tails from DVD without network and logged in 9.028

And I prepare Tails for memory erasure tests 0.402

When I fill a 128 MiB file with a known pattern on the root filesystem 15.995

# ensure the pattern is in memory due to tmpfs, not to disk cache

And I drop all kernel caches 2.462

Then patterns cover at least 128 MiB in the guest's memory 2.680

Output 1

Pattern coverage: 100.000% (128 MiB out of 128 MiB reference memory)

When I trigger shutdown 0.013

Then I find very few patterns in the guest's memory after 20 seconds 22.909

13.898%

13.898% of the free memory still has the pattern, but less than 0.800% was expected.
<false> is not true. (Test::Unit::AssertionFailedError)
