From 55f7ba830d40d438f0b0663a505e0c227fc68b6b Mon Sep 17 00:00:00 2001

Subject: mksquashfs: fix phys mem calculation for 32-bit processes on
PAE/64-bit kernels
When adding the code to base default memory usage on physical memory
(by default use 25% of physical memory), I made an oversight. I assumed
the process would be able to address 25% of physical memory.
However, for 32-bit processes running on a PAE kernel or 64-bit kernel,
25% of physical memory can easily exceed the addressible memory for a
32-bit process, e.g. if a machine has 24 GB of physical memory, the
code would asume the process could easily use 6 GB.
A 32-bit process by definition can only address 4 GB (32-bit pointers).
But, due to the typical kernel/user-space split (1GB/3GB, or 2GB/2GB)
on PAE kernels, a 32-bit process may only be able to address 2 GB.
So, if Mksquashfs is a 32-bit application running on a PAE/64-bit kernel,
the code assumes it can address much more memory than it really can, which
means it runs out of memory.
The fix is to impose a maximum default limit on 32-bit kernels, or
otherwise to never use a value more than 25% of the address space. If
we assume the maximum address space is 2 GB, then the maximum becomes
512 MB. But, given most kernels used the 1GB/3GB split, that may be
unduely conservative, and 25% of 3 GB (756 MB) may be better. This
patch compromises on 640 MB, which is mid-way between the 512 MB and 756 MB
values. It is also the fixed default value previously used by Mksquashfs.
This patch also alters the code which imposes a maximum size. Previously
it was believed limiting to the physical memory size was adequate. But
obviously this needs to be updated to take into account a 32-bit process
may only be able to address 2 GB. In the process I've also taken the
opportunity to limit all requests to no more than 75% of physical memory.

.TH MKSQUASHFS 1 "2014\-05\-13" "4.3" "create and append squashfs filesystems"

.SH SYNOPSIS
\fBmksquashfs\fR \fISOURCE\fR [\fISOURCE2\fR \fI...\fR] \fIDESTINATION\fR [\fIOPTIONS\fR]
.SH DESCRIPTION
Squashfs is a highly compressed read\-only filesystem for Linux. It uses zlib compression to compress both files, inodes and directories. Inodes in the system are very small and all blocks are packed to minimize data overhead. Block sizes greater than 4K are supported up to a maximum of 64K.
.PP
Squashfs is intended for general read\-only filesystem use, for archival use (i.e. in cases where a .tar.gz file may be used), and in constrained block device/memory systems (e.g. embedded systems) where low overhead is needed.
