Bug ID: 265937
Summary: linprocfs: process size incorrect
Product: Base System
Version: 12.3-RELEASE
Hardware: amd64
OS: Any
Status: New
Severity: Affects Some People
Priority: ---
Component: kern
Assignee: [email protected]
Reporter: [email protected]
On our FreeBSD 12.3 systems, I've detected that the process size
column in a `linprocfs` process status file (`<pid>/stat`) derived
from the `ki_size` structure is reading four times higher than it
should be, compared to values returned by e.g. `ps` and `top`.
The reason appears to be the use of the P2K macro in this line:
sys/compat/linprocfs/linprocfs.c:1019
```C
PS_ADD("vsize", "%ju", P2K((uintmax_t)kp.ki_size));
```
https://github.com/freebsd/freebsd-src/blob/c8e7070ce3d98c3aa0b08249afe1d6d887f37f31/sys/compat/linprocfs/linprocfs.c#L1019
ki_size is calculated elsewhere from vm_map.size, but I could find
nothing to say explicitly whether .size is counted in pages or kB.
The issue is still present in the 14.x source.
