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 9.149

And I prepare Tails for memory erasure tests 0.542

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 3.972

Output 1

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

When I kill the allocating process 0.246

Then I find very few patterns in the guest's memory after 3 seconds 6.069

Output 1

Pattern coverage: 0.000% (0 MiB out of 873 MiB reference memory)

Pattern coverage: 0.000% (0 MiB out of 868 MiB reference memory)

# write cache

When I fill the USB drive with a known pattern 2.516

Then I find very few patterns in the guest's memory after 3 seconds 6.135

Output 1

Pattern coverage: 0.000% (0 MiB out of 868 MiB reference memory)

# read cache

When I mount the USB drive again 0.984

And I read the content of the test FS 0.661

Then patterns cover at least 99% of the test FS size in the guest's memory 3.271

Output 1

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

When I umount the USB drive 0.453

Then I find very few patterns in the guest's memory 2.581

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 2.790

Then patterns cover at least 99% of the test FS size in the guest's memory 3.050

Output 1

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

When I umount the USB drive 1.469

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 7.947

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 14.870

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

And I drop all kernel caches 11.063

Then patterns cover at least 128 MiB in the guest's memory 2.650

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 21.873

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)
