Tools: hv: Reopen the devices if read() or write() returns errors The state machine in the hv_utils driver can run out of order in some corner cases, e.g. if the kvp daemon doesn't call write() fast enough due to some reason, kvp_timeout_func() can run first and move the state to HVUTIL_READY; next, when kvp_on_msg() is called it returns -EINVAL since kvp_transaction.state is smaller than HVUTIL_USERSPACE_REQ; later, the daemon's write() gets an error -EINVAL, and the daemon will exit(). We can reproduce the issue by sending a SIGSTOP signal to the daemon, wait for 1 minute, and send a SIGCONT signal to the daemon: the daemon will exit() quickly. We can fix the issue by forcing a reset of the device (which means the daemon can close() and open() the device again) and doing extra necessary clean-up.

Tools: hv: Add an example script to retrieve DNS entries To keep the KVP daemon code free of distro specific details, we invoke an external script to retrieve the DNS entries. This is an example script that was used to test the KVP code. This script has to be implemented in a Distro specific fashion. For instance on distros that ship with Network Manager enabled, this script can be based on NM APIs. Signed-off-by: K. Y.

tools: hv: change http to https in hv_kvp_daemon.c Rationale: Reduces attack surface on kernel devs opening the links for MITM as HTTPS traffic is much harder to manipulate. Deterministic algorithm: For each file: If not .svg: For each line: If doesn't contain \bxmlns\b: For each link, \bhttp://[^# \t\r\n]*(?:\w|/): If both the HTTP and HTTPS versions return 200 OK and serve the same content: Replace HTTP with HTTPS.

vmbus_testing: fix wrong python syntax for integer value comparison stable inclusion from stable-5.10.195 commit bb8a4a36321dab92c6178130caee7f1c001f6e64 category: bugfix issue: #I9HO7R CVE: NA Signed-off-by: wanxiaoqing <wanxiaoqing@huawei.com> --------------------------------------- [ Upstream commit ed0cf84e9cc42e6310961c87709621f1825c2bb8 ] It is incorrect in python to compare integer values using the "is" keyword. The "is" keyword in python is used to compare references to two objects, not their values. Newer version of python3 (version 3.8) throws a warning when such incorrect comparison is made. For value comparison, "==" should be used. Fix this in the code and suppress the following warning: /usr/sbin/vmbus_testing:167: SyntaxWarning: "is" with a literal. Did you mean "=="?
