https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=248216 Bug ID: 248216 Summary: linprocfs: Steam, Valve Anti-Cheat and /proc/<pid>/maps formatting. Product: Base System Version: 12.1-RELEASE Hardware: Any OS: Any Status: New Severity: Affects Only Me Priority: --- Component: kern Assignee: bugs@FreeBSD.org Reporter: iwtcex@gmail.com Created attachment 216717 --> https://bugs.freebsd.org/bugzilla/attachment.cgi?id=216717&action=edit that single space patch With some popular multiplayer games (such as Counter-Strike: Global Offensive) the Linux Steam client likes to occasionally scan the game process memory, presumably as part anti-cheat measures. Turns out the client also expects each inode entry to be followed by a space character, otherwise the parsing code crashes. The other related issue is that mapping information often doesn't fit into the pseudofs (?) 128 Kib limit, which results in a truncated map file. That occasionally leads to a Steam crash as well (depends on the exact truncation point). -- You are receiving this mail because: You are the assignee for the bug.help
