commit 3b83a22057b71e7df2b960d3997fb4474910f30e
Author: Wayne Davison <way...@samba.org>
Date: Wed Sep 2 08:56:34 2009 -0700
Define and use "our_gid" variable.
----------------------------------------
In this commit effective process gid determined once (in main.c), but after
client connect and daemon forked effective gid may be different (when you use
the 'gid' option in config file).
Now this commit was merged in 3.1.x thus broken some use cases.
Simple test case:
1. Prepare destination catalog:
rm -rf /tmp/dst && mkdir /tmp/dst && chmod 755 /tmp/dst && chown nobody:nobody
/tmp/dst
2. Prepare minimal rsyncd.conf:
--------------------------
pid file = /var/run/rsyncd.pid
uid = nobody
gid = nobody
read only = no
use chroot = no
[dst]
path = /tmp/dst
--------------------------
3. Start rsyncd as standalone daemon with standard rc script.
4. Try to rsync empty file belongs to group wheel (gid==0).
touch /tmp/src && chown 0:0 /tmp/src && rsync -av /tmp/src localhost::dst/
--------------------------------
sending incremental file list
src
rsync: chgrp ".src.tIDLzz" (in dst) failed: Operation not permitted (1)
sent 79 bytes received 111 bytes 380.00 bytes/sec
total size is 0 speedup is 0.00
rsync error: some files/attrs were not transferred (see previous errors) (code
23) at main.c(1165) [sender=3.1.1]
--------------------------------
With this commit rollbacked - operation is restored.
