(main): Parse all options if HASH_ALGO_CKSUM, and disallow --tag, --zero, and --check with the traditional bsd, sysv, and crc checksums for now. * src/local.mk: Reorganize to include all digest modules in cksum. * tests/misc/cksum-a.sh: Add a new test. * tests/misc/b2sum.sh: Update to default to checking with cksum, as b2sum's implementation diverges a bit from the others. * tests/local.mk: Reference the new test. * doc/coreutils.texi (cksum invocation): Adjust the summary to identify the new mode, and document the new --algorithm option. * man/cksum.x: Adjust description to be more general. * man/*sum.x: Add [See Also] section referencing cksum(1). * NEWS: Mention the new feature. 2021-09-15T14:35:53Z Pádraig Brady P@draigBrady.com 2021-09-05T22:32:36Z urn:sha1:6a5c561b4fb3018d284d03747c612527e0c89571 * cfg.mk: Adjust cksum.c to not require config.h and support a main (for crctab) without calling bindtextdomain(). * po/POTFILES.in: Remove cksum_pclmul.c since it no longer concerns itself with diagnostics. * src/cksum.c: Refactor to just providing stream digest, and digest printing functionality. * src/cksum.h: Adjust to the new interface. * src/cksum_pclmul.c: Remove diagnostics, and determine errors internally. * src/crctab.c: Separate from cksum.h since that's now included multiple times. * src/digest.c: Provide cksum(1) functionality if -DHASH_ALGO_CKSUM * src/local.mk: Adjust to new crctab.c and HASH_ALGO_CKSUM define. 2021-09-15T14:35:53Z Pádraig Brady P@draigBrady.com 2021-08-29T18:34:32Z urn:sha1:eb17c610d442cc8180c21b382a806bff40cea1f4 Since digest will be providing all digest functionality, refactor sum.c into it. * po/POTFILES.in: sum.c no longer has translatable strings so remove. * src/digest.c: Call out to new stream interfaces in sum.c * src/local.mk: Adjust sources for the sum binary. * src/sum.c: Provide a stream interface for BSD and SYSV digests. * src/sum.h: A new file to declare the exported functions in sum.c 2021-09-15T14:35:53Z Pádraig Brady P@draigBrady.com 2021-08-29T13:50:00Z urn:sha1:f0b32e79cc2cd184619ecb2037b4c9c88daaa428 md5sum.c will be the base for all digest functions, so rename accordingly. * src/md5sum.c: Rename to ... * src/digest.c: ... renamed from md5sum.c * scripts/git-hooks/commit-msg: Allow digest: commit prefix. * po.POTFILES.in: Adjust to new name. * src/local.mk: Likewise. 2021-05-15T15:14:11Z Pádraig Brady P@draigBrady.com 2021-05-15T11:40:45Z urn:sha1:26eccf6c98696c50f4416ba2967edc8676870716 This is now only used on 10 year old linux kernels, and performs a sync before each copy. * src/copy.c (extent_copy): Remove function and all callers. * src/extent-scan.c: Remove. * src/extent-scan.h: Remove. * src/fiemap.h: Remove. * src/local.mk: Adjust for removed files. * NEWS: Adjust to say fiemap is removed. 2021-05-02T19:51:37Z Kristoffer Brånemyr ztion1@yahoo.se 2021-02-20T11:27:17Z urn:sha1:4064c57380621399b54217a64c2c2bed1d0dccd1 Use cpuid to detect CPU support for avx2 instructions. Performance was seen to improve by 5x for a file with only newlines, while the performance for a file with no such characters is unchanged. * configure.ac [USE_AVX2_WC_LINECOUNT]: A new conditional, set when __get_cpuid_count() and avx2 compiler intrinsics are supported. * src/wc.c (avx2_supported): A new function using __get_cpuid_count() to determine if avx2 instructions are supported. (wc_lines): A new function refactored from wc(), which implements the standard line counting logic, and provides the fallback implementation for when avx2 is not supported. * src/wc_avx2.c: A new module to implement using avx2 intrinsics. * src/local.mk: Reference the new module. Note we build as a separate lib so that it can be portably built with separate -mavx2 etc. flags. 2021-03-15T12:44:22Z Kristoffer Brånemyr ztion1@yahoo.se 2021-02-03T09:35:22Z urn:sha1:4b9118cdb316093e1733264d229c6b7279179e1e Use cpuid to detect CPU support for hardware instruction.

Rewrite the code that it uses the recommended selabel_lookup instead. * m4/jm-macros.m4 (coreutils_MACROS): Do not check for matchpathcon_init_prefix, as it is no longer used. * src/copy.c (set_file_security_ctx): Omit process_local arg, as it is equivalent to !x->set_security_context. All callers changed. * src/copy.h (struct cp_options): set_security_context is now of type struct selabel_handle *, not bool. All uses changed. * src/cp.c, src/install.c, src/mkdir.c, src/mkfifo.c, src/mknod.c: * src/mv.c: Include selinux/label.h. (main): Use selabel_open for set_security context. * src/install.c (matchpathcon_init_prefix): Remove; now unused. (get_labeling_handle): New static function. (setdefaultfilecon, main): Use it. (setdefaultfilecon): Do something regardless of ENABLE_MATCHPATHCON, which seems to be a revenant macro. (setdefaultfilecon): Use selabel_lookup instead of the obsolescent matchpathcon. Report an error unless it fails due to ENOENT. * src/local.mk (src_ginstall_CPPFLAGS): Remove. * src/selinux.c: Include selinux/label.h Do not include die.h, error.h, canonicalize.h. (defaultcon, restorecon_private, restorecon): New arg HANDLE. All callers changed. Use selabel_lookup rather than matchpathcon. (restorecon_private, restorecon): Don’t lose track of errno. * src/selinux.c, src/selinux.h: (restorecon): Don’t call ‘error’; that’s the caller’s job. Use HAVE_SELINUX_LABEL_H, not HAVE_SELINUX_SELINUX_H, in case there is some weird system with the former but not the latter. * src/selinux.h (struct selinux_handle): Add forward decl.
