* Transparent data encryption and metadata authenticationEdward Shishkin2013-11-131-0/+23
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | .. in the systems with non-trusted server This new functionality can be useful in various cloud technologies. It is implemented via a special encryption/crypt translator,which works on the client side and performs encryption and authentication; 1. Class of supported algorithms The crypt translator can support any atomic symmetric block cipher algorithms (which require to pad plain/cipher text before performing encryption/decryption transform (see glossary in atom.c for definitions). In particular, it can support algorithms with the EOF issue (which require to pad the end of file by extra-data). Crypt translator performs translations user -> (offset, size) -> (aligned-offset, padded-size) ->server (and backward), and resolves individual FOPs (write(), truncate(), etc) to read-modify-write sequences. A volume can contain files encrypted by different algorithms of the mentioned class. To change some option value just reconfigure the volume. Currently only one algorithm is supported: AES_XTS. Example of algorithms, which can not be supported by the crypt translator: 1. Asymmetric block cipher algorithms, which inflate data, e.g. RSA; 2. Symmetric block cipher algorithms with inline MACs for data authentication. 2. Implementation notes. a) Atomic algorithms Since any process in a stackable file system manipulates with local data (which can be obsoleted by local data of another process), any atomic cipher algorithm without proper support can lead to non-POSIX behavior. To resolve the "collisions" we introduce locks: before performing FOP->read(), FOP->write(), etc. the process should first lock the file. b) Algorithms with EOF issue Such algorithms require to pad the end of file with some extra-data. Without proper support this will result in losing information about real file size. Keeping a track of real file size is a responsibility of the crypt translator. A special extended attribute with the name "trusted.glusterfs.crypt.att.size" is used for this purpose. All files contained in bricks of encrypted volume do have "padded" sizes. 3. Non-trusted servers and Metadata authentication We assume that server, where user's data is stored on is non-trusted. It means that the server can be subjected to various attacks directed to reveal user's encrypted personal data. We provide protection against such attacks. Every encrypted file has specific private attributes (cipher algorithm id, atom size, etc), which are packed to a string (so-called "format string") and stored as a special extended attribute with the name "trusted.glusterfs.crypt.att.cfmt". We protect the string from tampering. This protection is mandatory, hardcoded and is always on. Without such protection various attacks (based on extending the scope of per-file secret keys) are possible. Our authentication method has been developed in tight collaboration with Red Hat security team and is implemented as "metadata loader of version 1" (see file metadata.c). This method is NIST-compliant and is based on checking 8-byte per-hardlink MACs created(updated) by FOP->create(), FOP->link(), FOP->unlink(), FOP->rename() by the following unique entities: . file (hardlink) name; . verified file's object id (gfid). Every time, before manipulating with a file, we check it's MACs at FOP->open() time. Some FOPs don't require a file to be opened (e.g. FOP->truncate()). In such cases the crypt translator opens the file mandatory. 4. Generating keys Unique per-file keys are derived by NIST-compliant methods from the a) parent key; b) unique verified object-id of the file (gfid); Per-volume master key, provided by user at mount time is in the root of this "tree of keys". Those keys are used to: 1) encrypt/decrypt file data; 2) encrypt/decrypt file metadata; 3) create per-file and per-link MACs for metadata authentication. 5. Instructions Getting started with crypt translator Example: 1) Create a volume "myvol" and enable encryption: # gluster volume create myvol pepelac:/vols/xvol # gluster volume set myvol encryption on 2) Set location (absolute pathname) of your master key: # gluster volume set myvol encryption.master-key /home/me/mykey 3) Set other options to override default options, if needed. Start the volume. 4) On the client side make sure that the file /home/me/mykey exists and contains proper per-volume master key (that is 256-bit AES key). This key has to be in hex form, i.e. should be represented by 64 symbols from the set {'0', ..., '9', 'a', ..., 'f'}. The key should start at the beginning of the file. All symbols at offsets >= 64 are ignored. 5) Mount the volume "myvol" on the client side: # glusterfs --volfile-server=pepelac --volfile-id=myvol /mnt After successful mount the file which contains master key may be removed. NOTE: Keeping the master key between mount sessions is in user's competence. ********************************************************************** WARNING! Losing the master key will make content of all regular files inaccessible. Mount with improper master key allows to access content of directories: file names are not encrypted. ********************************************************************** 6. Options of crypt translator 1) "master-key": specifies location (absolute pathname) of the file which contains per-volume master key. There is no default location for master key. 2) "data-key-size": specifies size of per-file key for data encryption Possible values: . "256" default value . "512" 3) "block-size": specifies atom size. Possible values: . "512" . "1024" . "2048" . "4096" default value; 7. Test cases Any workload, which involves the following file operations: ->create(); ->open(); ->readv(); ->writev(); ->truncate(); ->ftruncate(); ->link(); ->unlink(); ->rename(); ->readdirp(). 8. TODOs: 1) Currently size of IOs issued by crypt translator is restricted by block_size (4K by default). We can use larger IOs to improve performance.

* bd: posix/multi-brick support to BD xlatorM. Mohan Kumar2013-11-131-0/+40
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Current BD xlator (block backend) has a few limitations such as * Creation of directories not supported * Supports only single brick * Does not use extended attributes (and client gfid) like posix xlator * Creation of special files (symbolic links, device nodes etc) not supported Basic limitation of not allowing directory creation is blocking oVirt/VDSM to consume BD xlator as part of Gluster domain since VDSM creates multi-level directories when GlusterFS is used as storage backend for storing VM images. To overcome these limitations a new BD xlator with following improvements is suggested. * New hybrid BD xlator that handles both regular files and block device files * The volume will have both POSIX and BD bricks. Regular files are created on POSIX bricks, block devices are created on the BD brick (VG) * BD xlator leverages exiting POSIX xlator for most POSIX calls and hence sits above the POSIX xlator * Block device file is differentiated from regular file by an extended attribute * The xattr 'user.glusterfs.bd' (BD_XATTR) plays a role in mapping a posix file to Logical Volume (LV). * When a client sends a request to set BD_XATTR on a posix file, a new LV is created and mapped to posix file. So every block device will have a representative file in POSIX brick with 'user.glusterfs.bd' (BD_XATTR) set. * Here after all operations on this file results in LV related operations. For example opening a file that has BD_XATTR set results in opening the LV block device, reading results in reading the corresponding LV block device. When BD xlator gets request to set BD_XATTR via setxattr call, it creates a LV and information about this LV is placed in the xattr of the posix file. xattr "user.glusterfs.bd" used to identify that posix file is mapped to BD. Usage: Server side: [root@host1 ~]# gluster volume create bdvol host1:/storage/vg1_info?vg1 host2:/storage/vg2_info?vg2 It creates a distributed gluster volume 'bdvol' with Volume Group vg1 using posix brick /storage/vg1_info in host1 and Volume Group vg2 using /storage/vg2_info in host2. [root@host1 ~]# gluster volume start bdvol Client side: [root@node ~]# mount -t glusterfs host1:/bdvol /media [root@node ~]# touch /media/posix It creates regular posix file 'posix' in either host1:/vg1 or host2:/vg2 brick [root@node ~]# mkdir /media/image [root@node ~]# touch /media/image/lv1 It also creates regular posix file 'lv1' in either host1:/vg1 or host2:/vg2 brick [root@node ~]# setfattr -n "user.glusterfs.bd" -v "lv" /media/image/lv1 [root@node ~]# Above setxattr results in creating a new LV in corresponding brick's VG and it sets 'user.glusterfs.bd' with value 'lv:<default-extent-size' [root@node ~]# truncate -s5G /media/image/lv1 It results in resizig LV 'lv1'to 5G New BD xlator code is placed in xlators/storage/bd directory. Also add volume-uuid to the VG so that same VG can't be used for other bricks/volumes. After deleting a gluster volume, one has to manually remove the associated tag using vgchange <vg-name> --deltag <trusted.glusterfs.volume-id:<volume-id>> Changes from previous version V5: * Removed support for delayed deleting of LVs Changes from previous version V4: * Consolidated the patches * Removed usage of BD_XATTR_SIZE and consolidated it in BD_XATTR. Changes from previous version V3: * Added support in FUSE to support full/linked clone * Added support to merge snapshots and provide information about origin * bd_map xlator removed * iatt structure used in inode_ctx. iatt is cached and updated during fsync/flush * aio support * Type and capabilities of volume are exported through getxattr Changes from version 2: * Used inode_context for caching BD size and to check if loc/fd is BD or not. * Added GlusterFS server offloaded copy and snapshot through setfattr FOP. As part of this libgfapi is modified. * BD xlator supports stripe * During unlinking if a LV file is already opened, its added to delete list and bd_del_thread tries to delete from this list when a last reference to that file is closed. Changes from previous version: * gfid is used as name of LV * ? is used to specify VG name for creating BD volume in volume create, add-brick. gluster volume create volname host:/path?vg * open-behind issue is fixed * A replicate brick can be added dynamically and LVs from source brick are replicated to destination brick * A distribute brick can be added dynamically and rebalance operation distributes existing LVs/files to the new brick * Thin provisioning support added. * bd_map xlator support retained * setfattr -n user.glusterfs.bd -v "lv" creates a regular LV and setfattr -n user.glusterfs.bd -v "thin" creates thin LV * Capability and backend information added to gluster volume info (and --xml) so that management tools can exploit BD xlator. * tracing support for bd xlator added TODO: * Add support to display snapshots for a given LV * Display posix filename for list-origin instead of gfid Change-Id: I00d32dfbab3b7c806e0841515c86c3aa519332f2 BUG: 1028672 Signed-off-by: M.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | * When a writev call occurs, the client compresses the data before sending it to server. On the server, compressed data is decompressed. Similarly, when a readv call occurs, the server compresses the data before sending it to client. On the client, the compressed data is decompressed. Thus the amount of data sent over the wire is minimized. * Compression/Decompression is done using Zlib library. * During normal operation, this is the format of data sent over wire : <compressed-data> + trailer(8) The trailer contains the CRC32 checksum and length of original uncompressed data.

* libglusterfs: Add monotonic clocking counter for timer threadHarshavardhana2013-10-151-1/+4
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | gettimeofday() returns the current wall clock time and timezone. Using these functions in order to measure the passage of time (how long an operation took) therefore seems like a no-brainer. This time suffer's from some limitations: a. They have a low resolution: “High-performance” timing by definition, requires clock resolutions into the microseconds or better. b. They can jump forwards and backwards in time: Computer clocks all tick at slightly different rates, which causes the time to drift. Most systems have NTP enabled which periodically adjusts the system clock to keep them in sync with “actual” time. The adjustment can cause the clock to suddenly jump forward (artificially inflating your timing numbers) or jump backwards (causing your timing calculations to go negative or hugely positive). In such cases timer thread could go into an infinite loop. From 'man gettimeofday': ---------- .. .. The time returned by gettimeofday() is affected by discontinuous jumps in the system time (e.g., if the system administrator manually changes the system time). If you need a monotonically increasing clock, see clock_gettime(2). .. .. ---------- Rationale: For calculating interval timing for Timer thread, all that’s needed should be clock as a simple counter that increments at a stable rate. This is necessary to avoid the jumps which are caused by using "wall time", this counter must be monotonic that can never “tick” backwards, ever.

* features/changelog: changelog translatorAvra Sengupta2013-07-221-0/+5
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This is the initial version of the Changelog Translator. What is it ----------- Goal is to capture changes performed on a GlusterFS volume. The translator needs to be loaded on the server (bricks) and captures changes in a plain text file inside a configured directory path (controlled by "changelog-dir", should be somewhere in <export>/.glusterfs/changelog by default). Changes are classified into 3 types: - Data: : TYPE-I - Metadata : TYPE-II - Entry : TYPE-III Changelog file is rolled over after a certain time interval (defauls to 60 seconds) after which a changelog is started. The thing to be noted here is that for a time interval (time slice) multiple changes for an inode are recorded only once (ie. say for 100+ writes on an inode that happens within the time slice has only a single corresponding entry in the changelog file). That way we do not bloat up the changelog and also save lots of writes. Changelog Format ----------------- TYPE-I and TYPE-II changes have the gfid on the entity on which the operation happened. TYPE-III being a entry op requires the parent gfid and the basename. Changelog format has been kept to a minimal and it's upto the consumers to do the heavy loading of figuring out deletes, renames etc.. A single changelog file records all three types of changes, with each change starting with an identifier ("D": DATA, "M": METADATA and "E": ENTRY). Option is provided for the encoding type (See TUNABLES). Consumers ---------- The only consumer as of today would be geo-replication, although backup utilities, self-heal, bit-rot detection could be possible consumers in the future. CLI ---- By default, change-logging is disabled (the translator is present in the server graph but does nothing). When enabled (via cli) each brick starts to log the changes. There are a set of tunable that can be used to change the translators behaviour: - enable/disable changelog (disabled by default) gluster volume set <volume> changelog {on|off} - set the logging directory (<brick>/.glusterfs/changelogs is the default) gluster volume set <volume> changelog-dir /path/to/dir - select encoding type (binary (default) or ascii) gluster volume set <volume> encoding {binary|ascii} - change the rollover time for the logs (60 secs by default) gluster volume set <volume> rollover-time <secs> - when secs > 0, changelog file is not open()'d with O_SYNC flag - and fsync is trigerred periodically every <secs> seconds. gluster volume set <volume> fsync-interval <secs> features/changelog: changelog consumer library (libgfchangelog) A shared library is provided for the consumer of the changelogs for easy acess via APIs. Application can link against this library and request for changelog updates. Conversion of binary logs to human-readable ascii format is also taken care by the library which keeps a copy of the changelog in application provided working directory.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch enables to use syslog as log target in addition to the default. The logs are sent in CEE format (http://cee.mitre.org/). This logging can be disabled using compile time option by ./configure --disable-syslog (or) rpmbuild glusterfs.tar.gz --without syslog The framework provides two api void gf_openlog (const char *ident, int option, int facility); void gf_syslog (int error_code, int facility_priority, char *format, ...); consumers need to call gf_openlog() prior to gf_syslog() like the way traditional syslog function calls. error_code is mandatory when using gf_syslog(). For example, gf_openlog (NULL, -1, -1); gf_syslog (GF_ERR_DEV, LOG_ERR, "error reading configuration file"); Using syslog, admin is free to configure logger to * reduce repeated log messages * forward logs to remote logger * execute a command on certain log pattern * alert people for certain log pattern by email, snmp etc * and many more Change-Id: Ibacbcbbc547192893fc4a46b387496b622e4811f BUG: 928648 Signed-off-by: Bala.FA <barumuga@redhat.com> Reviewed-on: http://review.gluster.org/4915 Tested-by: Gluster Build System <jenkins@build.gluster.com> Reviewed-by: Vijay Bellur <vbellur@redhat.com>

| | | | | | | | | | | | | | | | | | | | | The bd-xlator can not be built successfully on certain Debian distributions due to a missing declaration of lvm_lv_from_name(). This function is available for linking, but it does not exist in the header file. This change adds a detection for lvm_lv_from_name() in both the library for linking, and the declaration in the header file. If the 1st is missing, the bd-xlator can not be built, and if only the 2nd one is missing, we'll declare lvm_lv_from_name() ourselves. This makes it possible to build the bd-xlator on the affected Debian distributions too.

* config: better (i.e. more portable) test for libxml2Kaleb S. KEITHLEY2013-03-251-5/+4
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Over the weekend I tried to build on MacOS X¹ and ran into the following issues: 1) The recent change to autogen.sh to test for pkg-config falls down. 2) After removing the pkg-config test in autogen.sh, w/o pkg-config the PKG_CHECK_MODULES macro invocation in configure[.ac] falls down. N.B. Solaris users run into this too, even through there's a (broken) pkg-config package that can be installed. 3) There are other problems in the code related to fuse that are beyond the scope of this. It seems that pkg-config is only a requirement for the definition of the PKG_CHECK_MODULES macro used to detect libxml2. Since this seems to be inherently unportable — at least to MacOS X and Solaris — I'd like to: A) Change the use of the PKG_CHECK_MODULES macro to the more portable AM_PATH_XML2 macro provided by the libxml2 package in /usr/.../share/aclocal/libxml.m4 2) Revisit the decision to add the check for pkg-config in autogen.sh in BZ 921817. For now this is just an rfc. If people are agreeable I'll reenter this change against BZ 921817. ¹Mountain Lion 10.8.3, XCode 4.6.1 Change-Id: I237b1ed8919088345b8fd943423b2a6ad289981b BUG: 921817 Signed-off-by: Kaleb S.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Add a new server storage xlator 'bd mapper'. Intention of this xlator is to add block device backend support to gluster. It exports block devices as regular files to the gluster client. The immediate goal of this translator is to use logical volumes to store VM images and expose them as files to QEMU/KVM. Given Volume group is represented as directory and its logical volumes as files. By exporting LUNs/LVs as regular files, it becomes possible to: * Associate each VM to a LV/LUN * Use file system commands like cp to take copy of VM images * Create linked clones of VM by doing LV snapshot at server side * Implement thin provisioning by developing a qcow2 translator As of now this patchset maps only logical volumes. BD Mapper volume file specifies which Volume group to export to the client. BD xlator exports the volume group as a directory and all logical volumes under that as regular files. BD xlator uses lvm2-devel APIs for getting the list of Volume Groups and Logical Volumes in the system. The eventual goal of this work is to support thin provisioning, snapshot, copy etc of VM images seamlessly in glusterfs storage environment BUG: 805138 Change-Id: I13b69d39d7fd199c101c8e9e4f2cf10772bdc3dd Signed-off-by: M.

* Add OCF compliant resource agents for glusterd and volumesFlorian Haas2012-10-241-0/+9
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | These resource agents plug glusterd into Open Cluster Framework (OCF) compliant cluster resource managers, like Pacemaker. The glusterd RA is fairly trivial; it simply manages the glusterd daemon like any upstart or systemd job would, except that Pacemaker can do it in a cluster-aware fashion. The volume RA is a bit more involved; It starts a volume and monitors individual brick's daemons in a cluster aware fashion, recovering bricks when their processes fail. Note that this does NOT imply people would deploy GlusterFS servers in pairs, or anything of that nature. Pacemaker has the ability to deploy cluster resources as clones, meaning glusterd and volumes would be configured as follows in a Pacemaker cluster: primitive p_glusterd ocf:glusterfs:glusterd \ op monitor interval="30" primitive p_volume_demo ocf:glusterfs:volume \ params volname="demo" \ op monitor interval="10" clone cl_glusterd p_glusterd \ meta interleave="true" clone cl_volume_demo p_volume_demo \ meta interleave="true" ordered="true" colocation c_volume_on_glusterd inf: cl_volume_demo cl_glusterd order o_glusterd_before_volume 0: cl_glusterd cl_volume_demo The cluster status then looks as follows (in a 4-node cluster; note the configuration above could be applied, unchanged, to a cluster of any number of nodes): ============ Last updated: Fri Mar 30 10:54:50 2012 Last change: Thu Mar 29 17:20:17 2012 via crmd on gluster02.h Stack: openais Current DC: gluster03.h - partition with quorum Version: 1.1.6-3.el6-a02c0f19a00c1eb2527ad38f146ebc0834814558 4 Nodes configured, 4 expected votes 8 Resources configured. ============ Online: [ gluster02.h gluster03.h gluster04.h gluster01.h ] Clone Set: cl_glusterd [p_glusterd] Started: [ gluster02.h gluster03.h gluster04.h gluster01.h ] Clone Set: cl_volume_demo [p_volume_demo] Started: [ gluster01.h gluster02.h gluster03.h gluster04.h ] This is also a way of providing automatic glusterd and brick recovery in systems where neither upstart nor systemd are available.

* build: remove useless explicit -fPIC -shared fromJeff Darcy2012-10-031-0/+1
| | | | | | | | | | | | | | | | | | | | CFLAGS libtool will automatically add "-fPIC" to the compiler command line as needed, so there is no need to specify it separately. "-shared" is normally a linker flag and has an odd effect when used with libtool --mode=compile, namely that it inhibits production of static objects. For that however, using AC_DISABLE_STATIC is a lot simpler.
