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 8.853

And I prepare Tails for memory erasure tests 0.409

When I start a process allocating 128 MiB of memory with a known pattern 2.499

Then patterns cover at least 128 MiB in the guest's memory 3.322

Output 1

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

When I kill the allocating process 0.267

Then I find very few patterns in the guest's memory after 3 seconds 5.819

Output 1

Pattern coverage: 0.000% (0 MiB out of 901 MiB reference memory)

Output 1

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 2.268

Output 1

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

When I umount "/mnt" 0.832

Then I find very few patterns in the guest's memory 3.817

Output 1

Pattern coverage: 0.000% (0 MiB out of 893 MiB reference memory)

# write cache

When I fill the USB drive with a known pattern 2.732

Then patterns cover at least 75% of the test FS size in the guest's memory 4.109

Output 1

Pattern coverage: 86.570% (110 MiB out of 127 MiB reference memory)

When I umount the USB drive 2.076

Then I find very few patterns in the guest's memory after 3 seconds 6.747

Output 1

Pattern coverage: 0.000% (0 MiB out of 893 MiB reference memory)

# read cache

When I mount the USB drive again 0.264

And I read the content of the test FS 0.625

Then patterns cover at least 99% of the test FS size in the guest's memory 4.297

Output 1

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

When I umount the USB drive 1.182

And I prepare Tails for memory erasure tests 0.536

When I plug and mount a 128 MiB USB drive with an ext4 filesystem encrypted with password "asdf" 32.736

Then I find very few patterns in the guest's memory 2.414

Output 1

Pattern coverage: 0.000% (0 MiB out of 888 MiB reference memory)

# write cache

When I fill the USB drive with a known pattern 1.786

Then patterns cover at least 99% of the test FS size in the guest's memory 2.769

Output 1

Pattern coverage: 106.113% (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 0.003

Steps

Given I have started Tails from DVD without network and logged in 9.256

And I prepare Tails for memory erasure tests 0.412

When I fill a 128 MiB file with a known pattern on the root filesystem 15.930

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

And I drop all kernel caches 1.731

Then patterns cover at least 128 MiB in the guest's memory 2.589

Output 1

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

When I trigger shutdown 0.012

Then I find very few patterns in the guest's memory after 20 seconds 22.556

14.286%

14.286% of the free memory still has the pattern, but less than 0.800% was expected.
<false> is not true. (Test::Unit::AssertionFailedError)
