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 8.073

And I prepare Tails for memory erasure tests 0.734

When I start a process allocating 128 MiB of memory with a known pattern 1.261

Then patterns cover at least 128 MiB in the guest's memory 3.420

Output 1

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

When I kill the allocating process 0.782

Then I find very few patterns in the guest's memory after 3 seconds 5.338

Output 1

Pattern coverage: 0.000% (0 MiB out of 685 MiB reference memory)

Scenario Erasure of tmpfs data on unmount

Hooks

Before features/support/hooks.rb:269 0.002

Steps

Given I have started Tails from DVD without network and logged in 7.930

And I prepare Tails for memory erasure tests 0.383

And I find very few patterns in the guest's memory 2.739

Output 1

Pattern coverage: 0.000% (0 MiB out of 691 MiB reference memory)

When I mount a 128 MiB tmpfs on "/mnt" and fill it with a known pattern 1.457

Then patterns cover at least 99% of the test FS size in the guest's memory 2.804

Output 1

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

When I umount "/mnt" 0.430

Then I find very few patterns in the guest's memory after 3 seconds 6.047

Output 1

Pattern coverage: 0.000% (0 MiB out of 691 MiB reference memory)

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 7.940

And I prepare Tails for memory erasure tests 0.432

When I plug and mount a 128 MiB USB drive with a vfat filesystem 9.175

Then I find very few patterns in the guest's memory 2.948

Output 1

Pattern coverage: 0.000% (0 MiB out of 709 MiB reference memory)

# write cache

When I fill the USB drive with a known pattern 2.037

Then patterns cover at least 75% of the test FS size in the guest's memory 2.828

74.490%

74.490% of the test FS size (127.599609375 MiB) has the pattern, but more than 75.000% was expected.
<false> is not true. (Test::Unit::AssertionFailedError)

Output 1

Pattern coverage: 74.490% (95 MiB out of 127 MiB reference memory)

When I umount the USB drive 0.000

Then I find very few patterns in the guest's memory after 3 seconds 0.000

# read cache

When I mount the USB drive again 0.000

And I read the content of the test FS 0.000

Then patterns cover at least 99% of the test FS size in the guest's memory 0.000

When I umount the USB drive 0.000

Then I find very few patterns in the guest's memory after 3 seconds 0.000
