+Subject: [PATCH 02/11] Improve tar_getcwd
+
+* src/common.h (tar_getcwd): Return pointer is const.
+* src/misc.c (wd) : New member.
+(chdir_arg): Initialize cwd.
+(tar_getcwd): Use cwd member to cache the result. Take into
+account absolute pathnames,
+(normalize_filename): Don't free the value
+returned from tar_getcwd.
+* src/names.c (name_next_elt): Remove leftover call chdir().
+* tests/Makefile.am: Add new tests.
+* tests/testsuite.at: Likewise.
+
+* tests/incr08.at: New testcase.
+* tests/remfiles04.at: New testcase.
+* tests/remfiles05.at: New testcase.
+* tests/remfiles06.at: New testcase.
+* tests/remfiles07.at: New testcase.

++# Description: In tar 1.26 listed-incremental with -C and absolute path
++# would malfunction under certain conditions due to buggy filename
++# normalization.
++#
++# The value returned by normalize_filename() is used to populate the "caname"
++# field in both the "directory" structure in incremen.c and the "name"
++# structure in names.c, and in both cases that field is then used in the
++# "hash" and "compare" functions for the related hash tables. Thus, the
++# fact that the returned value doesn't reflect the operation of previous
++# "-C" options means that it's possible for two different directories to
++# be given the same "caname" value in the hashed structure and thus end up
++# being confused with each other.
++#
++# The bug is triggered when dumping both relative paths after -C and
++# absolute paths that match the process' current working directory.

+Subject: [PATCH 11/11] Work around unlinkat bug on FreeBSD and GNU/Hurd
+
+* src/unlink.c (dunlink_insert): New function.
+(flush_deferred_unlinks): Skip cwds and nonempty directories
+at the first pass. If force is requested, run a second pass
+removing them.
+(queue_deferred_unlink): Make sure current working directory
+entries are sorted in descending order by the value of dir_idx.
+This makes sure they will be removed in right order, which works
+around unlinkat bug on FreeBSD and GNU/Hurd.
+* tests/remfiles08b.at: Remove expected failure.
+* tests/remfiles09b.at: Likewise.

++@node List Extended Attributes
++@unnumberedsubsec Listing xattrs, POSIX ACLs and SELinux context
++
++From upstream GNU tar 1.26.9, tar is able to store, extract and list extended
++file attributes. Listing of those attributes is then active only in verbose and
++double-verbose mode.
++
++This section exercises how to list attributes on examples. Lets start with
++simple verbose mode. This output is inspired by GNU @command{ls -l} command
++output.
++
++@itemize @bullet
++@item
++Show only pure extended attributes.
++

++-rw-rw-r--* user/group 0 2012-08-08 15:15 xattrs.txt
++@end smallexample
++
++Note the asterisk on the third line! It reflects the situation that the file
++'xattrs.txt' has some extended attribute set. The default mode (same as if you

++As is in @pxref{Option Summary} section described, tar by default stores all
++extended attributes that are available (not only 'user.*' domain). It means
++that the SELinux context and POSIX ACLs (because they are implemented using the
++generic extended attributes on usual file system) may be stored twice sometimes
++-- firstly in "raw" file system binary format and secondly in more portable way
++-- using appropriate system calls (invoked by @command{tar} options
++@option{--selinux} and @option{--acls}).

++@opindex xattrs
++@item --xattrs
++This option causes @command{tar} to store, restore or list the extended file
++attributes (for information about extended attributes see @command{man(5)
++attr}).
++
++Note that all extended attributes are stored "as-is" (in file system binary
++format) and the resulting archive may be not fully portable. See the
++@option{--selinux} and @option{--acls} options when you want to deal with these
++types of extended attributes in a better way.
++
++The @option{--xattrs} option implies the option @option{--format=posix} when
++tar is in @option{--create} operation mode. It is the only one format which
++hase usable headers for storing additional file information like extended
++attributes are.
++
++By default, all extended attributes are stored into the archive. The reason is
++that we want to make the backup process as complete as possible by default. On
++the other hand, during extracting only the 'user.*' domain is extracted by
++default. Anyway, this default behaviour may be easily modified by the
++@option{--xattrs-include} and @option{--xattrs-exclude} options.
++
++When you list an archive in verbose mode
++(@command{tar --xattrs --verbose -tf archive.tar}), tar shows the '*' character
++after the permissions string of concrete file ringht to tell you that at least
++one extended attribute is stored with corresponding file.
++
++Double verbose mode (@command{tar --xattrs -tvvf archive.tar}) prints the
++extended attribute length (in bytes) and its ASCII key (for printed examples
++@pxref{List Extended Attributes}).
++
++@option{--xattrs} option has no equivalent short option.
++
++Warnings which occur during impossible writing of extended attributes to
++a file system may be suppressed using the @option{--warning=no-xattr-write}
++option.
++
++@opindex no-xattrs
++@item --no-xattrs
++This option causes @command{tar} not to store/extract or list the current
++extended attributes. This option does not affect options @option{--no-selinux}
++or @option{--no-acls}.
++
++The @option{--no-xattrs} option has no equivalent short option name.
++
++@opindex xattrs-include
++@opindex xattrs-exclude
++@item --xattrs-include=MASK
++@itemx --xattrs-exclude=MASK
++
++These options allows the xattr store/restore/list process to be more fine
++grained. The default configuration is that @option{--create} mode handles all
++available extended attributes and the @option{--extract}/@option{--list} mode
++handles only 'user.*' domain. These options may be used for editing of this
++default behaviour.
++
++@itemize @bullet
++@item
++Lets say we want to store all attributes except some "public restricted" domain
++(e.g. 'user.restricted.*' domain. The correct way how to do it is:
++
++@command{tar --xattrs --xattrs-include='*' --xattrs-exclude='user.restricted.*'
++-cf archive.tar FILES}
++@item
++And, when we want to extract only some specific domain from an archive - we can
++use:
++
++@command{tar --xattrs --xattrs-include='security.capability' -xf archive.tar
++FILES}
++@end itemize
++
++Multiple passed include/exclude patterns are combined together. The attribute
++is covered then only if (1) at least one of all include patterns matches its
++keyword and (2) no exclude pattern matches its keyword.
++
++When only include pattern is set - exclude pattern is left in default mode (and
++vice versa).
++
++@opindex selinux
++@item --selinux
++This option causes @command{tar} to store/extract/list the SELinux context
++information into/from an archive. Command @command{tar} is able to show info
++whether the SELinux context is present in archived file using the verbose
++listing mode (@command{tar --selinux -tvf archive.tar}). It shows the '.'
++character after permission string in that case. Double-verbose listing mode
++(@command{tar -tvvf archive.tar}) then prints the full SELinux context to
++standard output, @pxref{List Extended Attributes} for printed example.
++
++This option implies the @option{--format=posix} when @command{tar} works in
++@option{--create} operation mode.
++
++Warnings complaining that SELinux context may not be written to a file system
++may be suppressed by the @option{--warning=no-xattr-write} option.
++
++The @option{--selinux} option has no equivalent short option name.
++
++@opindex no-selinux
++@item --no-selinux
++This option causes @command{tar} not to store the current SELinux security
++context information in the archive and not to extract any SELinux information in
++an archive.
++
++The @option{--no-selinux} option has no equivalent short option name.
++
++@opindex acls
++@item --acls
++This option causes @command{tar} to store the current POSIX access control lists
++into the archive or restore POSIX ACLs from an archive. It also allows
++@command{tar} to show whether archived file contains ACLs when the verbose mode
++is active (@option{tar --acls -tvf} shows the symbol '+' after the permission
++characters in that case). Double-verbose mode allows @command{tar} to list
++contained POSIX ACLs (@command{tar --acls -tvvf archive.tar}), for printed
++examples @pxref{List Extended Attributes}.
++
++This option implies the @option{--format=posix} when @command{tar} works in
++@option{--create} operation mode.
++
++Warnings complaining that POSIX ACLs may not be written to a file system may be
++suppressed by the @option{--warning=no-xattr-write} option.
++
++The @option{--acls} option has no equivalent short form.
++
++@opindex no-acls
++@item --no-acls
++This option causes @command{tar} not to store the current POSIX ACL into the

+
+List posix archives containing sparse files >8GB correctly and do not fail.
+This fixes also bug in format of listing for sparse files >8GB - now the
+real size is printed instead of the effective one (this is not strictly
+posix format related).
+
+* src/list.c: Remove redundant assignment.
+* src/tar.h: Add new 'real_size' and 'real_size_set' fields in
+ tar_stat_info struct.
+* src/xheader.c: Correctly handle (especially sparse) file sizes directly in
+ xheader_decode().

+Subject: [PATCH] Improve compression format recognition
+
+Some comressed archives can pass the checksum test, which makes tar
+treat them as uncompressed archives.
+
+* src/buffer.c (check_compressed_archive): Test the checksum only
+if the block we read looks like a valid tar header (i.e. has
+a magic string).

+Subject: [PATCH] Fix non-deterministic archive type detection
+
+Due to analysis of partly uninitialized read-ahead buffer
+(short_read call), we sometimes mistakenly classified very small
+compressed archives as non-compressed; which in turn caused
+extraction failure.
+
+* src/buffer.c (check_compressed_archive): Don't assume that
+archives smaller than BLOCKSIZE could be non-compressed, as tar
+header always has at least one block.

++* Support for POSIX ACLs, extended attributes and SELinux context.
++
++Starting with this version tar is able to store, extract and list
++extended file attributes, POSIX.1e ACLs and SELinux context. This is
++controlled by the command line options --xattrs, --acls and --selinux,
++correspondingly. Each of these options has a `--no-' counterpart
++(e.g. --no-xattrs), which disables the corresponding feature.
++Additionally, the options --xattrs-include and --xattrs-exclude allow
++you to selectively control for which files to store (or extract) the
++extended attributes.

+.SH NAME
+tar \- manual page for tar 1.26
+.SH SYNOPSIS
+.B tar
+[\fIOPTION\fR...] [\fIFILE\fR]...
+.SH DESCRIPTION
+GNU `tar' saves many files together into a single tape or disk archive, and can
+restore individual files from the archive.
+
+Note that this manual page contains just very brief description (or more like
+a list of possible functionality) originally generated by the
+.B
+help2man
+utility. The full documentation for
+.B tar
+is maintained as a Texinfo manual. If the
+.B info
+and
+.B tar
+programs are properly installed at your site, the command
+.B `info tar'
+should give you access to the complete manual.
+.SH EXAMPLES

+%description
+The GNU tar program saves many files together in one archive and can
+restore individual files (or all of the files) from that archive. Tar
+can also be used to add supplemental files to an archive and to update
+or list files in the archive. Tar includes multivolume support,
+automatic archive compression/decompression, the ability to perform
+remote archives, and the ability to perform incremental and full
+backups.
+
+If you want to use tar for remote backups, you also need to install
+the rmt package on the remote box.
