From 3c67d83a8afb391f20bc53d36a0cebea6897b3e2 Mon Sep 17 00:00:00 2001 From: Tony Hutter Date: Wed, 15 Jun 2016 15:47:05 -0700 Subject: OpenZFS 4185 - add new cryptographic checksums to ZFS: SHA-512, Skein, Edon-R Reviewed by: George Wilson Reviewed by: Prakash Surya Reviewed by: Saso Kiselkov Reviewed by: Richard Lowe Approved by: Garrett D'Amore Ported by: Tony Hutter OpenZFS-issue: https://www.illumos.org/issues/4185 OpenZFS-commit: https://github.com/openzfs/openzfs/commit/45818ee Porting Notes: This code is ported on top of the Illumos Crypto Framework code: https://github.com/zfsonlinux/zfs/pull/4329/commits/b5e030c8dbb9cd393d313571dee4756fbba8c22d The list of porting changes includes: - Copied module/icp/include/sha2/sha2.h directly from illumos - Removed from module/icp/algs/sha2/sha2.c: #pragma inline(SHA256Init, SHA384Init, SHA512Init) - Added 'ctx' to lib/libzfs/libzfs_sendrecv.c:zio_checksum_SHA256() since it now takes in an extra parameter. - Added CTASSERT() to assert.h from for module/zfs/edonr_zfs.c - Added skein & edonr to libicp/Makefile.am - Added sha512.S. It was generated from sha512-x86_64.pl in Illumos. - Updated ztest.c with new fletcher_4_*() args; used NULL for new CTX argument. - In icp/algs/edonr/edonr_byteorder.h, Removed the #if defined(__linux) section to not #include the non-existant endian.h. - In skein_test.c, renane NULL to 0 in "no test vector" array entries to get around a compiler warning. - Fixup test files: - Rename -> , -> , - Remove and define NOTE() as NOP. - Define u_longlong_t - Rename "#!/usr/bin/ksh" -> "#!/bin/ksh -p" - Rename NULL to 0 in "no test vector" array entries to get around a compiler warning. - Remove "for isa in $($ISAINFO); do" stuff - Add/update Makefiles - Add some userspace headers like stdio.h/stdlib.h in places of sys/types.h. - EXPORT_SYMBOL *_Init/*_Update/*_Final... routines in ICP modules. - Update scripts/zfs2zol-patch.sed - include in sha2_impl.h - Add sha2.h to include/sys/Makefile.am - Add skein and edonr dirs to icp Makefile - Add new checksums to zpool_get.cfg - Move checksum switch block from zfs_secpolicy_setprop() to zfs_check_settable() - Fix -Wuninitialized error in edonr_byteorder.h on PPC - Fix stack frame size errors on ARM32 - Don't unroll loops in Skein on 32-bit to save stack space - Add memory barriers in sha2.c on 32-bit to save stack space - Add filetest_001_pos.ksh checksum sanity test - Add option to write psudorandom data in file_write utility --- lib/libzfs/libzfs_dataset.c | 6 ++++++ lib/libzfs/libzfs_sendrecv.c | 4 +++- 2 files changed, 9 insertions(+), 1 deletion(-) (limited to 'lib/libzfs') diff --git a/lib/libzfs/libzfs_dataset.c b/lib/libzfs/libzfs_dataset.c index 6b09cb6da..5ecf96985 100755 --- a/lib/libzfs/libzfs_dataset.c +++ b/lib/libzfs/libzfs_dataset.c @@ -1477,6 +1477,12 @@ zfs_setprop_error(libzfs_handle_t *hdl, zfs_prop_t prop, int err, "property setting is not allowed on " "bootable datasets")); (void) zfs_error(hdl, EZFS_NOTSUP, errbuf); + } else if (prop == ZFS_PROP_CHECKSUM || + prop == ZFS_PROP_DEDUP) { + (void) zfs_error_aux(hdl, dgettext(TEXT_DOMAIN, + "property setting is not allowed on " + "root pools")); + (void) zfs_error(hdl, EZFS_NOTSUP, errbuf); } else { (void) zfs_standard_error(hdl, err, errbuf); } diff --git a/lib/libzfs/libzfs_sendrecv.c b/lib/libzfs/libzfs_sendrecv.c index e409899a2..f70e34107 100644 --- a/lib/libzfs/libzfs_sendrecv.c +++ b/lib/libzfs/libzfs_sendrecv.c @@ -61,6 +61,7 @@ #include #include #include +#include /* in libzfs_dataset.c */ extern void zfs_setprop_error(libzfs_handle_t *, zfs_prop_t, int, char *); @@ -365,10 +366,11 @@ cksummer(void *arg) if (ZIO_CHECKSUM_EQUAL(drrw->drr_key.ddk_cksum, zero_cksum) || !DRR_IS_DEDUP_CAPABLE(drrw->drr_checksumflags)) { + SHA256_CTX ctx; zio_cksum_t tmpsha256; zio_checksum_SHA256(buf, - payload_size, &tmpsha256); + payload_size, &ctx, &tmpsha256); drrw->drr_key.ddk_cksum.zc_word[0] = BE_64(tmpsha256.zc_word[0]); -- cgit v1.2.3
