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 8.275

And I prepare Tails for memory erasure tests 0.416

When I start a process allocating 128 MiB of memory with a known pattern 1.281

Then patterns cover at least 128 MiB in the guest's memory 4.103

Output 1

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

When I kill the allocating process 1.071

Then I find very few patterns in the guest's memory 5.145

Output 1

Pattern coverage: 0.000% (0 MiB out of 890 MiB reference memory)

Pattern coverage: 0.000% (0 MiB out of 894 MiB reference memory)

When I mount a 128 MiB tmpfs on "/mnt" and fill it with a known pattern 1.688

Then patterns cover at least 99% of the test FS size in the guest's memory 4.233

Output 1

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

When I umount "/mnt" 1.518

Scenario Erasure of read and write disk caches on unmount: vfat

Hooks

Before features/support/hooks.rb:269 0.002

Steps

Given I have started Tails from DVD without network and logged in 8.137

And I prepare Tails for memory erasure tests 0.489

Then I find very few patterns in the guest's memory 4.838

Output 1

Pattern coverage: 0.000% (0 MiB out of 887 MiB reference memory)

# write cache

When I fill the USB drive with a known pattern 7.504

Then patterns cover at least 86% of the test FS size in the guest's memory 5.892

Output 1

Pattern coverage: 86.790% (110 MiB out of 127 MiB reference memory)

When I umount the USB drive 5.337

Then I find very few patterns in the guest's memory 4.442

Output 1

Pattern coverage: 0.000% (0 MiB out of 887 MiB reference memory)

# read cache

When I mount the USB drive again 0.279

And I read the content of the test FS 0.511

Then patterns cover at least 99% of the test FS size in the guest's memory 3.801

Output 1

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

When I umount the USB drive 0.632

Then I find very few patterns in the guest's memory 4.226

Output 1

Pattern coverage: 0.000% (0 MiB out of 887 MiB reference memory)

Hooks

Before features/support/hooks.rb:269 0.002

Steps

Given I have started Tails from DVD without network and logged in 8.131

And I prepare Tails for memory erasure tests 0.411

When I plug and mount a 128 MiB USB drive with an ext4 filesystem encrypted with password "asdf" 36.262

Then I find very few patterns in the guest's memory 3.823

Output 1

Pattern coverage: 0.000% (0 MiB out of 917 MiB reference memory)

# write cache

When I fill the USB drive with a known pattern 3.256

Then patterns cover at least 99% of the test FS size in the guest's memory 3.393

Output 1

Pattern coverage: 106.113% (97 MiB out of 91 MiB reference memory)

When I umount the USB drive 1.431

Then I find very few patterns in the guest's memory 3.503

Output 1

Pattern coverage: 0.000% (0 MiB out of 917 MiB reference memory)

# read cache

When I mount the USB drive again 4.610

And I read the content of the test FS 0.821

Then patterns cover at least 99% of the test FS size in the guest's memory 3.188

Output 1

Pattern coverage: 106.116% (97 MiB out of 91 MiB reference memory)

Scenario Erasure of the overlayfs read-write branch on shutdown

Hooks

Before features/support/hooks.rb:269 0.002

Steps

Given I have started Tails from DVD without network and logged in 8.427

And I prepare Tails for memory erasure tests 0.453

When I fill a 128 MiB file with a known pattern on the root filesystem 18.110

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

And I drop all kernel caches 1.954

Then patterns cover at least 128 MiB in the guest's memory 3.468

Output 1

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

When I trigger shutdown 0.019

And I wait 20 seconds 20.019

Output 1

Slept for 20 seconds

Then I find very few patterns in the guest's memory 3.631

14.431%

14.431% of the free memory still has the pattern, but less than 0.800% was expected.
<false> is not true. (Test::Unit::AssertionFailedError)
