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.

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.

mkdir,mkfifo,mknod: with -Z, create SMACK security context

2013-07-01T13:33:05Z

Enable creation of SMACK security context with -Z command-line switch if SMACK is enabled. * mkdir.c (main): Set process security context to given SMACK label. * mkfifo.c (main): Likewise. * mknod.c (main): Likewise. * src/local.mk: link mk{dir, fifo, nod} with libsmack. * NEWS: Mention the new feature.

ls: with -Z, show SMACK security context

2013-06-24T20:00:14Z

Enable showing of file SMACK security with '-Z' command-line switch if SMACK is enabled. Showing SMACK context of a file does not strictly require SMACK to be enabled but this required to make choice whether to show SELinux or SMACK security context. * src/ls.c (getfilecon_cache): Retrieve SMACK context if available. (gobble_file): Handle SMACK context similarly to SELinux context. * src/local.mk: Link lsl with libsmack. * NEWS: Mention the new feature. * .mailmap: Merge the Author's 2 email addresses.

id: with -Z, show SMACK security context

2013-05-08T10:55:08Z

Adds an optional dependency on libsmack. * m4/jm-macros.m4: Look for the smack library/header. * src/id.c (main): Output the smack context if available. * src/local.mk: Link with libsmack if available. * NEWS: Mention the new feature.

maint: improve make src/fs-magic-compare

2013-03-24T02:29:57Z

* README-release: fix the `make` command, and mention how to get the latest results without requring running a system with the latest kernel. * src/local.mk (src/fs-latest-magic.h): A new target to document how/where to place the latest magic header. (src/fs-kernel-magic): Adjust to include separately downloaded header if available. (src/fs-magic): Undefine MANPAGER as it may impact the ability to pipe the output of man(1). (fs-magic-compare): Don't echo the commands run as they're distracting from the output which needs to be examined.

maint: update all copyright year number ranges

2013-01-01T03:51:20Z

Run "make update-copyright", but then also run this, perl -pi -e 's/2\d\d\d-//' tests/sample-test to make that one script use the single most recent year number.

build: fix cygwin build issues

2012-12-19T11:29:12Z

* doc/local.mk (doc/constants.texi): Ensure the doc directory is present which is needed when doing a non source dir build, when the doc/constants.texi target is built before other doc targets. * src/local.mk: Add $(EXEEXT) to the make-prime-list calls.

factor: tidy up primes.h again

2012-11-17T00:52:10Z

See Stefano Lattarini in . * src/local.mk (BUILT_SOURCES): Put $(top_srcdir)/src/primes.h here (MAINTAINERCLEANFILES): ... instead of here.

factor: maintainer builds primes.h, not builder

2012-11-12T16:32:31Z

With this change, the maintainer builds primes.h and it is part of the tarball. primes.h's contents are not architecture-specific. * .gitignore: Remove /src/primes.h. * src/factor.c: Include verify.h. (W): New constant. Verify that uintmax_t lacks holes and that W is no wider than the integers used to generate primes.h. * src/local.mk (EXTRA_DIST): Add src/primes.h. (BUILT_SOURCES, CLEANFILES): Remove src/primes.h. ($(top_srcdir)/src/primes.h): Rename from src/primes.h. Do not depend on src/make-prime-list. Instead, use sub-make to build, so that we build primes.h only if it does not exist. * src/make-prime-list.c: Include , for ULONG_MAX. (wide_uint): Define to uintmax_t or unsigned __int128 if not #defined. (struct prime, binvert, process_prime): Use it instead of uintmax_t. (print_wide_uint): New function. This generates the proper pinv value regardless of the width of uintmax_t on the target, so long as the width doesn't exceed that of the width of wide_uint on the maintainer host that generated src/primes.h. (output_primes): Use it. Output WIDE_UINT_BITS, too. Let the target compute its own lim, since its uintmax_t may be narrower than ours. (SZ): Remove. * src/primes.h: New file, generated with 128-bit integers and usable on any host where uintmax_t's width is no greater than 128 bits.
