2017-11-04ecryptfs: remove private bin2hex implementationRasmus Villemoes2-16/+8
Calling sprintf in a loop is not very efficient, and in any case, we already have an implementation of bin-to-hex conversion in lib/ which we might as well use. Note that ecryptfs_to_hex used to nul-terminate the destination (and the kernel doc was wrong about the required output size), while bin2hex doesn't. [All but one user of ecryptfs_to_hex explicitly nul-terminates the result anyway.] Signed-off-by: Rasmus Villemoes <linux@rasmusvillemoes.dk> [tyhicks: Include <linux/kernel.h> in ecryptfs_kernel.h] Signed-off-by: Tyler Hicks <tyhicks@canonical.com>

2017-10-29selftests: Introduce a new test case to tc testsuiteChris Mi3-5/+40
In this patchset, we fixed a tc bug. This patch adds the test case that reproduces the bug. To run this test case, user should specify an existing NIC device: # sudo ./tdc.py -d enp4s0f0 This test case belongs to category "flower". If user doesn't specify a NIC device, the test cases belong to "flower" will not be run. In this test case, we create 1M filters and all filters share the same action. When destroying all filters, kernel should not panic. It takes about 18s to run it.
