Scenario Erasure of memory freed by killed userspace processes

Hooks

Before features/support/hooks.rb:269 0.002

Steps

Given I have started Tails from DVD without network and logged in 8.094

And I prepare Tails for memory erasure tests 0.464

When I start a process allocating 128 MiB of memory with a known pattern 3.512

Then patterns cover at least 128 MiB in the guest's memory 3.525

Output 1

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

When I kill the allocating process 1.458

Then I find very few patterns in the guest's memory 3.751

Output 1

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

Steps

Given I have started Tails from DVD without network and logged in 8.070

Pattern coverage: 0.000% (0 MiB out of 884 MiB reference memory)

When I mount a 128 MiB tmpfs on "/mnt" and fill it with a known pattern 1.752

Then patterns cover at least 99% of the test FS size in the guest's memory 3.802

Output 1

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

When I umount "/mnt" 0.869

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

Hooks

Before features/support/hooks.rb:269 0.003

Steps

Given I have started Tails from DVD without network and logged in 8.058

And I prepare Tails for memory erasure tests 0.373

Then I find very few patterns in the guest's memory 4.058

Output 1

Pattern coverage: 0.000% (0 MiB out of 886 MiB reference memory)

# write cache

When I fill the USB drive with a known pattern 2.806

Then patterns cover at least 86% of the test FS size in the guest's memory 3.659

Output 1

Pattern coverage: 89.555% (114 MiB out of 127 MiB reference memory)

When I umount the USB drive 1.399

Then I find very few patterns in the guest's memory 3.491

Output 1

Pattern coverage: 0.000% (0 MiB out of 886 MiB reference memory)

# read cache

When I mount the USB drive again 0.225

And I read the content of the test FS 0.620

Then patterns cover at least 99% of the test FS size in the guest's memory 4.068

Output 1

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

When I umount the USB drive 0.463

Then I find very few patterns in the guest's memory 4.378

Output 1

Pattern coverage: 0.000% (0 MiB out of 886 MiB reference memory)

Hooks

Before features/support/hooks.rb:269 0.003

Steps

Given I have started Tails from DVD without network and logged in 8.204

And I prepare Tails for memory erasure tests 0.402

When I plug and mount a 128 MiB USB drive with an ext4 filesystem encrypted with password "asdf" 36.079

Then I find very few patterns in the guest's memory 3.685

Output 1

Pattern coverage: 0.000% (0 MiB out of 881 MiB reference memory)

# write cache

When I fill the USB drive with a known pattern 2.421

Then patterns cover at least 99% of the test FS size in the guest's memory 3.022

Output 1

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

When I umount the USB drive 0.821

Then I find very few patterns in the guest's memory 3.304

Output 1

Pattern coverage: 0.000% (0 MiB out of 881 MiB reference memory)

# read cache

When I mount the USB drive again 5.054

And I read the content of the test FS 0.523

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 7.939

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 16.074

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

And I drop all kernel caches 7.073

Then patterns cover at least 128 MiB in the guest's memory 2.637

Output 1

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

When I trigger shutdown 0.015

And I wait 20 seconds 20.050

Output 1

Slept for 20 seconds

Then I find very few patterns in the guest's memory 3.312

14.414%

14.414% of the free memory still has the pattern, but less than 0.800% was expected.
<false> is not true. (Test::Unit::AssertionFailedError)
