The patches within the rsync-patches-3.4.0.tar.gz archive seem to contain new
unnecessary hunks that change the prefix from /usr to /usr/local. This was not
the case in 3.3.0.

I use the fileflags.diff patch in the MacPorts build of rsync, and with the
3.4.0 version of this patch, it does not build:

t_stub.c:34:14: error: redefinition of 'module_dirlen' with a different
type: 'unsigned int' vs 'int'
unsigned int module_dirlen = 0;
             ^
t_stub.c:31:5: note: previous definition is here
int module_dirlen = 0;
    ^
1 error generated.

This happens on NonStop x86 and ia64. I have been building/packaging Rsync for
years ? almost a decade in fact. I think this happened once before this year, in
fact.

 

It is equivalent to the more portable malloc/free, which I would prefer to have
in this series even if it has to be wrapped in a #if defined (__TANDEM) block.

 

This call is considered not portable and allocates on the stack instead of the
heap. This can cause performance issues as memory management on the heap is
generally given more attention by runtimes. The reason it is not supported on
NonStop is that the c99 compiler does not generate code for allocating on the
stack on this machine.

 

Please forgive me here, but adding a new dependency for a critical security fix
is rather painful.

We have just released version 3.4.0 of rsync. This release fixes 6 security
vulnerabilities found by two groups of security researchers.

 

You can find the new release links here:

 

 - https://rsync.samba.org/

 - https://download.samba.org/pub/rsync/src/

 

For details on the vulnerabilities please see this CERT advisory:

 

https://kb.cert.org/vuls/id/952657

 

The various distros should be doing security releases today

Many thanks to Simon Scannell, Pedro Gallegos, and Jasiel Spelman at Google
Cloud Vulnerability Research and Aleksei Gorban (Loqpa) for discovering these
vulnerabilities and working with the rsync project to develop and test fixes.

 

Also many thanks to Wayne Davison for assisting with the release process as this
is the first release I've done since 2002 when Wayne took over as the rsync
maintainer.

 

Andrew Tridgell

rsync maintainer (again!)
