version 8.22

2013-12-13T15:03:45Z

* NEWS: Record release date.

stat,tail: improve support for hostfs and smackfs

2013-12-13T14:05:53Z

hostfs is provided by the Linux UML subsystem. smackfs is provided by the Linux Smack security module. * src/stat.c (human_fstype): Add new file system ID definitions. * NEWS: Mention the improvement, and adjust for the fact that SNFS is a remote file system.

build: default to avoiding openssl system libraries

2013-12-13T02:28:11Z

* configure.ac: Don't change the gnulib default of 'no' for whether to link with openssl system libraries if available. Distributions can explicitly enable this as their policy allows. * NEWS: Adjust accordingly.

shuf: --repeat, not --repetitions; default --head-count is infinity

2013-12-06T17:55:55Z

Original problem reported by Philipp Thomas in . * NEWS: shuf --repeat, not shuf --repetitions. * doc/coreutils.texi (shuf invocation): * src/shuf.c (usage, long_opts, main): * tests/misc/shuf.sh: Likewise. Also, the default head-count is infinity.

doc: clarify that df now generally processes special files correctly

2013-12-05T23:59:36Z

Since v8.21-172-g33660b4, df not only treats symbolic link arguments differently, as stated there, but now generally processes special file arguments in a non-canonicalized form correctly: $ cd /dev && df-old sdb Filesystem 1K-blocks Used Available Use% Mounted on devtmpfs 1014572 48 1014524 1% /dev $ cd /dev && df-new sdb Filesystem 1K-blocks Used Available Use% Mounted on /dev/sdb 10190136 6039532 3609932 63% /home Document df's new behavior. * doc/coreutils.texi (df invocation): In the paragraph describing df's behavior regarding special file arguments, relax the condition for such special files from "... is an absolute name of ..." to "... resolves to ...". * NEWS (Bug fixes): Mention the new behavior also here.

md5sum, sha*sum: use libcrypto where available

2013-12-04T13:18:56Z

libcrypto is generally available and has well optimized crypto hash routines particular to various systems. For example, testing sha1sum with openssl-1.0.0j on an i3-2310M, gives a performance boost of about 40%: $ time sha1sum.old --tag ~/test.iso SHA1 (/home/padraig/test.iso) = 3c27f7ed01965fd2b89e22128fd62dc51a3bef30 real 0m4.692s user 0m4.499s sys 0m0.162s $ time sha1sum.new --tag ~/test.iso SHA1 (/home/padraig/test.iso) = 3c27f7ed01965fd2b89e22128fd62dc51a3bef30 real 0m2.685s user 0m2.512s sys 0m0.170s * configure.ac: By default, enable use of libcrypto if available. * src/local.mk: Link with libcrypto. * NEWS: Mention the md5sum and sha*sum improvements.

df: handle bind mounts when processing device nodes

2013-12-04T13:17:17Z

* src/df.c (get_disk): Use the same heuristic used in get_point() to select the shortest file system mount point, in an attempt to show the base mounted file system. * NEWS: Mention the bug fix.

df: dereference symlinks to disk device nodes

2013-12-04T13:16:27Z

This is so the matching for the device is done on the canonical name of the disk node, rather than on the path of the symlink. In any case the user will generally want to use the symlink target. * src/df.c (get_disk): Canonicalize the passed file, before matching against the list of mounted file system devices. Note we pass the original symlink name to the "file" output field, as the symlink target is usually available through the "source" field. * tests/df/df-symlink.sh: Test the dereferencing operation. * tests/local.mk: Mention the new test. * NEWS: Mention the fix.

df: remove long-obsolescent --megabytes option

2013-11-29T12:07:47Z

This option has been undocumented for 12 years [1], and warned about for a year [2]. [1] commit FILEUTILS-4_1_4-23-gd177203 [2] commit v8.17-43-g453ce92 * src/df.c (MEGABYTES_OPTION): Remove. (long_options): Remove "megabytes" element. (main): In the option parsing loop, remove the MEGABYTES_OPTION case. * NEWS: Mention the change.

selinux: adjust utils to run restorecon with -Z

2013-11-27T14:19:32Z

cp, mv, install, mkdir, mkfifo, mknod are adjusted so that: -Z no longer accepts an argument. -Z or --context without an argument do not warn without SELinux. --context with an argument will warn without SELinux. * src/local.mk: Reference the new selinux module where required. * src/system.h: Make the argument to --context optional. * src/mkdir.c: Likewise. Also handle the SMACK case for --context. Note we currently silently ignore -Z with SMACK. * src/mkfifo.c: Likewise. * src/mknod.c: Likewise. * src/install.c: Likewise. Note install(1) by default already set the context for target files to their system default, albeit with an older method. Use the -Z option to select between the old and new context restoration behavior, and document the differences and details for how context restoration is done in new and old methods, with a view disabling the old method entirely in future. * src/cp.c: Make the argument to --context optional. Note -Z implies --no-preserve=context. I.E. -Z overrides that aspect of -a no matter what order specified. (struct cp_options): Document the context handling options. (main): Check/adjust option combinations after all options are processed, to both simplify processing and to make handling independent of order of options on the command line. Also improve the diagnostics from a failed call to setfscreatecon(). (set_process_security_ctx): A new function, refactored to set the default context from the source file, or with the type adjusted as per the system default for the destination path. (set_file_security_ctx): A new function refactored to set the security context of an existing file, either based on the process context or the default system context for a path. (copy_internal): Use the refactored functions to simplify error handling and consistently fail or warn as needed. (copy_reg): Likewise. (copy_internal): With --preserve=context, also copy context from non regular files. Note for directories this may impact the copying of subsequent files to that directory? (copy_attr): If we're handling SELinux explicitly, then exclude to avoid the redudant copy with --preserve=context, and the problematic copy with -Z. Note SELinux attribute exclusion also now honors cp -a --no-preserve=context. Note there was a very small window over 10 years ago, where attr_copy_file was available, while attr_copy_check_permissions was not, so we don't bother adding an explicit m4 check for the latter function. * src/mv.c: Support --context, but don't allow specifying an argument. * src/chcon.c: Adjust a comment to be specific to SELinux. * src/runcon.c: Likewise. * src/copy.c: Honor the context settings to "restorecon" as appropriate. * src/copy.h: Add a new setting to select "restorecon" functionality. * tests/mkdir/selinux.sh: s/-Z/--context=/ * tests/cp/cp-a-selinux.sh: Augment this test with cases testing basic -Z functionality, and also test the various invalid option combinations and option precedence. * tests/mkdir/restorecon.sh: Add a new test for the more involved mkdir -Z handling, since the directory changing and non existent directories need to be specially handled. Also check the similar but simpler handling of -Z by mk{nod,fifo}. * tests/local.mk: Reference the new test. * doc/coreutils.texi (cp invocation): Update as per interface changes. (mv invocation): Likewise. (install invocation): Likewise. (mkfifo invocation): Likewise. (mknod invocation): Likewise. (mkdir invocation): Likewise. * NEWS: Mention the new feature and change in behavior.
