Bug ID: 258729
Summary: linprocfs regression: /compat/linux/proc/*/cwd wrongly
points to calling process's cwd for all PIDs
Product: Base System
Version: 13.0-RELEASE
Hardware: Any
OS: Any
Status: New
Severity: Affects Some People
Priority: ---
Component: kern
Assignee: [email protected]
Reporter: [email protected]
/compat/linux/proc/N/cwd is supposed to be a symlink to the CWD for PID N. In
FreeBSD 13, it's regressed to always being a symlink to the calling process's
CWD instead.
Example at https://gitlab.xfce.org/apps/xfce4-terminal/-/issues/121
The code is in sys/compat/linprocfs/linprocfs.c function linprocfs_doproccwd().
It got changed at least twice in 2020.
