== SRU Justification ==
Description: kernel: Fix memory leak on CCA and EP11 CPRB processing.
Symptom: Kernel memory not freed when CCA or EP11 CPRB processing fails.
Problem: kfree() in code error path missing.
Solution: Slight rework of the malloc and free places.
Reproduction: Run application which sends CCA or EP11 crypto requests
to the crypto card(s). Now switch the cards offline with
the help of chzcrypt. Monitor top or free output.

[Kernel-packages] [Bug 1775390] Re: kernel: Fix memory leak on CCA and EP11 CPRB processing.
This bug is awaiting verification that the kernel in -proposed solves
the problem. Please test the kernel and update this bug with the
results. If the problem is solved, change the tag 'verification-needed-
bionic' to 'verification-done-bionic'. If the problem still exists,
change the tag 'verification-needed-bionic' to 'verification-failed-
bionic'.
If verification is not done by 5 working days from today, this fix will
be dropped from the source code, and this bug will be closed.
See https://wiki.ubuntu.com/Testing/EnableProposed for documentation how
to enable and use -proposed. Thank you!

[Kernel-packages] [Bug 1775390] Re: kernel: Fix memory leak on CCA and EP11 CPRB processing.
I built a test kernel with commit 89a0c0ec0d2e3ce0ee9caa00f60c0c26ccf11c21. The test kernel can be downloaded from: http://kernel.ubuntu.com/~jsalisbury/lp1775390 Can you test this kernel and see if it resolves this bug? Note about installing test kernels: • If the test kernel is prior to 4.15(Bionic) you need to install the linux-image and linux-image-extra .deb packages. • If the test kernel is 4.15(Bionic) or newer, you need to install the linux-modules, linux-modules-extra and linux-image-unsigned .deb packages.
