If not set, rchecksum fop will use MD5 instead of SHA256. updates: #230 Change-Id: Id8ea1303777e6450852c0bc25503cda341a6aec2 Signed-off-by: Ravishankar N --- xlators/storage/posix/src/posix-common.c | 16 ++++++++++++++++ 1 file changed, 16 insertions(+) (limited to 'xlators/storage/posix/src/posix-common.c') diff --git a/xlators/storage/posix/src/posix-common.c b/xlators/storage/posix/src/posix-common.c index a67b3d7dc70..f1fa81e056b 100644 --- a/xlators/storage/posix/src/posix-common.c +++ b/xlators/storage/posix/src/posix-common.c @@ -387,6 +387,9 @@ posix_reconfigure (xlator_t *this, dict_t *options) GF_OPTION_RECONF ("max-hardlinks", priv->max_hardlinks, options, uint32, out); + + GF_OPTION_RECONF ("fips-mode-rchecksum", priv->fips_mode_rchecksum, + options, bool, out); ret = 0; out: return ret; @@ -1076,6 +1079,9 @@ posix_init (xlator_t *this) _private->create_directory_mask = create_directory_mask; GF_OPTION_INIT ("max-hardlinks", _private->max_hardlinks, uint32, out); + + GF_OPTION_INIT ("fips-mode-rchecksum", _private->fips_mode_rchecksum, + bool, out); out: if (ret) { if (_private) { @@ -1362,5 +1368,15 @@ struct volume_options options[] = { .description = "max number of hardlinks allowed on any one inode.\n" "0 is unlimited, 1 prevents any hardlinking at all." }, + { + .key = {"fips-mode-rchecksum"}, + .type = GF_OPTION_TYPE_BOOL, + .default_value = "off", + .op_version = {GD_OP_VERSION_4_0_0}, + .flags = OPT_FLAG_SETTABLE, + .tags = {"posix"}, + .description = "If enabled, posix_rchecksum uses the FIPS compliant" + "SHA256 checksum.
