The sosreport command's networking module collects various data from the kernel's sysctl configuration found in /proc/sys/net. Certain legacy paths in this directory are deprecated but maintained for compatibility reasons. Accessing these files generates a warning in the kernel logs.
Running sosreport on systems having deprecated sysctls would generate warnings as sos accessed these paths.
Sos now includes a blacklist for forbidden paths in this directory. No diagnostic information is lost since the content of these files is now provided under different parameter names that are already included in the report.
Full diagnostic information is now collected from the /proc/sys/net directory without generating unnecessary warnings in the system logs.
