- - The setting of flist->high in clean_flist() was wrong for an empty list.
- This could cause flist_find() to crash in certain rare circumstances
- (e.g. if just the right directory setup was around when --fuzzy was
- combined with --link-dest).
-
- - The outputting of hard-linked files when verbosity was > 1 was not right:
- without -i it would output the name of each hard-linked file as though
- it had been changed (it now outputs a "is hard linked" message for the
- file); with -i it would output all dots for the unchanged attributes of
- a hard-link (it now changes those dots to spaces, as is done for other
- totally unchanged items).
-
- - When backing up a changed symlink or device, get rid of any old backup
- item so that we don't get an already-exists error.
-
- - A couple places that were comparing a local and a remote modification-
- time were not honoring the --modify-window option.
-
- - Fixed a really old, minor bug that could cause rsync to warn about being
- unable to mkdir() a path that ends in "/." because it just created the
- directory (required --relative, --no-implied-dirs, a source path that
- ended in either a trailing slash or a trailing "/.", and a non-existing
- destination dir to tickle the bug in a recent version).
+ - An rsync daemon that is receiving files with "use chroot = no" no longer
+ sanitizes the symlink target strings. This means that each symlink's
+ value will now be accepted (and thus returned) with its symlink info
+ intact. Also, in order to keep things safe, all arg paths and any
+ dereferenced symlinks (e.g. via --copy-links or --keep-dirlinks) are
+ manually verified to ensure that no symlinks try to escape past the top
+ of the module's path. These changes make a non-chroot daemon behave the
+ same way as a chroot daemon with regard to symlinks, and also avoids a
+ potential problem where a pre-existing symlink could have escaped the
+ module's hierarchy.
+
+ - Fixed a overzealous sanitizing bug in the handling of the --*-dest
+ options (--link-dest, --copy-dest, and --compare-dest): if the copy's
+ destination dir is deeper than the top of the module's path, these
+ options now accept a safe number of ../ (parent-dir) references (since
+ these options are relative to the destination dir). The old code
+ incorrectly chopped off all "../" prefixes for these options, no matter
+ how deep the destination directory was in the module's hierarchy.
+
+ - Fixed a bug where a deferred info/error/log message could get sent
+ directly to the sender instead of being handled by rwrite() in the
+ generator. This fixes an "unexpected tag 3" fatal error, and should
+ also fix a potential problem where a deferred info/error message from
+ the receiver might bypass the log file and get sent only to the client
+ process. (These problems could only affect an rsync daemon that was
+ receiving files.)
+
+ - Make sure that the --link-dest option can still do its job even when -I
+ or --size-only is specified.
+
+ - The daemon now calls more timezone-using functions prior to doing a
+ chroot. This should help some C libraries to generate proper timestamps
+ from inside a chrooted daemon (and to not try to access /etc/timezone
+ over and over again).
+
+ - Fixed a bug in the handling of an absolute --partial-dir=ABS_PATH option:
+ it now deletes an alternate basis file from the partial-dir that was used
+ to successfully update a destination file.
