* bitrot/scrub: Scrubber fixesVenky Shankar2015-04-088-88/+314
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch fixes a handful of problem with scrubber which are detailed below. Scrubber used to skip objects for verification due to missing fd iterface to fetch versioning extended attributes. Similar to the inode interface, an fd based interface in POSIX is now introduced. Moreover, this patch also fixes potential false reporting by scrubber due to: An object gets dirtied and signed when scrubber is busy calculatingobject checksum. This is fixed by caching the signed version when an object is first inspected for stalenes, i.e., during pre-compute stage. This version is used to verify checksum in the post-compute stage when the signatures are compared for possible corruption. Side effect of _not_ sending signature length during signing resulted in "truncated" signature to be set for an object. Now, at the time of signing, the signature length is sent and is used in place of invoking strlen() to get signature length (which could have possible 00s). The signature length itself is not persisted in the signature xattr, but is calculated on-the-fly by substracting the xattr length by the "structure" header size. Some of the log entries are made more meaningful (as and aid for debugging).

* tests/bitrot-stub: Object versioning test(s)Venky Shankar2015-04-082-16/+31
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch introduces basic object versioning test(s) which is required for bitrot detection to work correctly. Basic test(s) such as opening a file in read-only mode, single open, multiple open()s are covered on FUSE mount _only_ as stub does not support anonymous fds yet. For this reason, the test case disables open-behind. Actual verification is implemented as a C source which makes use of the same on-disk data structures as used by the stub code. The data structures are moved to separate header file which is included by the test script. Such modularization helps in future enhancements to keep the version "data type" opaque and provide handful of APIs version checking (equal/greater/etc..). [ This is just a start and should grow over time as stub is enhanced and codebase matures. ] Change-Id: Ibee20e65a15b56bbdd59fd2703f9305b115aec7a BUG: 1201724 Signed-off-by: Venky Shankar <vshankar@redhat.com> Reviewed-on: http://review.gluster.org/10140 Reviewed-by: Raghavendra Bhat <raghavendra@redhat.com> Tested-by: Gluster Build System <jenkins@build.gluster.com> Reviewed-by: Vijay Bellur <vbellur@redhat.com>

| | | | | | | | | | | | | | | | | | | | | | | | | | | .. and potential bug fixes / memleak. While assigning initial version to an object, both extended attributes (namely, ongoing version and the default signing version) were persisted. This is optimized to just persist the ongoing version along with safe handling of xattr request(s) in it's absence. This is better than the earlier approach as the two xattr sets were not atomic anyway (allowing a request to sneak in between between two set operations). This also allows to perform sanity checks on objects during lookup()/getxattr(): objects with missing ongoing version but presence of signature are possible candidates of tampering (and catching implementation bugs). There were couple of instances in the code where versioning xattrs were incorrectly removed before in-memory versions were initialized, which have been fixed with this patch. A memory leak in the IPC code path is also fixed.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 1. Expected behavior of get_real_filename feature. A getxattr on a existing dir with glusterfs.get_real_filename:<filename> as key should result in one of the following things. a. A value returned for that key having the real filename (a file whose match is a case insensitive match to the filename passed in key). b. op_ret = -1 and errno set to ENOENT meaning that no such file exists under the specified dir in any case. c. op_ret = -1 and errno set to ENODATA. This is a case assuming no xlator interprets the glusterfs.get_real_filename key and it get passed down to the posix xlator. Naturally, posix xlator would not find any xattr with this key and would return ENODATA. This will be interpreted specially by the caller as the feature not being supported by underlying glusterfs. 2. What assumptions are wrong? Initially the key used to be user.glusterfs.get_real_filename. In that case, when posix xlator did a getxattr call it would have received ENODATA as error. However, the key has now changed to glusterfs.get_real_filename. This leads to a EOPNOTSUPP error instead. Considering the above information, this is a rewrite of get_real_filename logic in dht.

* Avoid conflict between contrib/uuid and system uuidEmmanuel Dreyfus2015-04-04113-935/+935
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | glusterfs relies on Linux uuid implementation, which API is incompatible with most other systems's uuid. As a result, libglusterfs has to embed contrib/uuid, which is the Linux implementation, on non Linux systems. This implementation is incompatible with systtem's built in, but the symbols have the same names. Usually this is not a problem because when we link with -lglusterfs, libc's symbols are trumped. However there is a problem when a program not linked with -lglusterfs will dlopen() glusterfs component. In such a case, libc's uuid implementation is already loaded in the calling program, and it will be used instead of libglusterfs's implementation, causing crashes. A possible workaround is to use pre-load libglusterfs in the calling program (using LD_PRELOAD on NetBSD for instance), but such a mechanism is not portable, nor is it flexible. A much better approach is to rename libglusterfs's uuid_* functions to gf_uuid_* to avoid any possible conflict. This is what this change attempts.

| | | | | | | | | | | | | | | | | | | | | | | | | | Functions store_eliminate_path() and wipe_eliminate_path() take eliminate as a plain pointer not pointer to pointer. Hence store_eliminate_path fails to hand the allocated and filled eliminate data out to the caller (in particular leaking memory), and wipe_eliminate_path() fails to NULL the freed eliminate path. This leads to several leak and access after free errors found by Coverity. This patch fixes the issue by handing in eliminate by reference and in the case of wipe_eliminate path, also NULLing out the free'd pointer. This fixes the following coverity IDs: CID 1288759 CID 1288790 Change-Id: I7520ae42c5f6e369a145bea67b4ff95b75d2ae73 BUG: 789278 Signed-off-by: Michael Adam <obnox@samba.org> Reviewed-on: http://review.gluster.org/10068 Tested-by: Gluster Build System <jenkins@build.gluster.com> Reviewed-by: Anoop C S <achiraya@redhat.com> Reviewed-by: Vijay Bellur <vbellur@redhat.com>
