* bit-rot xlator: strncpy()->sprintf(), reduce strlen()'sYaniv Kaul2018-08-311-3/+7

Instead, use snprintf(). Ensure sprintf() results do not truncate. Also: - save the result of strlen() and re-use it when possible. - move from strlen to SLEN or sizeof() for const strings. - move ret from int32 to int. Compile-tested only!

* features/bitrot: print the path of the corrupted objectsRaghavendra Bhat2018-05-041-0/+218
| | | | | | | | | | | | | | | | | | | | | | | | | Currently "gluster volume bitrot <volume name> scrub status" gives the list of the corrupted objects (files as of now). But only the gfids of those corrupted objects are seen and one has to do getfattr, find etc operations to get the actual path of those objects for removal etc. This change makes an attempt to print the path of those files as much as possible. * Try to get the path using the on disk gfid2path xattr. * If the above operation fails, then go for in memory path (provided that the object has its dentry properly created and linked in the inode table of the brick where the corrupted object is present) So the gfid to path resolution is a soft resolution, i.e. based on the inode and dentry cache in the brick's memory. If the path cannot be obtained via inode table also, then only gfid is printed.

* xlator/bitrot: flood of -Wformat-truncation warnings with gcc-7.1Kaleb S. KEITHLEY2017-10-041-67/+20
| | | | | | | | | | | | | | | | Starting in Fedora 26 which has gcc-7.1.x, -Wformat-trunction is enabled with -Wformat, resulting in a flood of new warnings. This many warnings is a concern because it makes it hard(er) to see other warnings that should be addressed. An example is at https://kojipkgs.fedoraproject.org//packages/glusterfs/3.12.0/1.fc28/data/logs/x86_64/build.log For more info see https://review.gluster.org/#/c/18267/ Change-Id: I7792d94da1e8109f3aaa857a94be40f2d2402684 BUG: 1492851 Signed-off-by: Kaleb S.

| | | | | | | | | | | | | | | | * As of now bit-rot-stub does versioning always. This leads lots of getxattr calls being made in lookups. So make object versioning optional.

* core: use readdir(3) with glibc, and associated cleanupKaleb S. KEITHLEY2016-07-181-14/+12
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Starting with glibc-2.23 (i.e. what's in Fedora 25), readdir_r(3) is marked as deprecated. Specifically the function decl in <dirent.h> has the deprecated attribute, and now warnings are thrown during the compile on Fedora 25 builds. The readdir(_r)(3) man page (on Fedora 25 at least) and World+Dog say that glibc's readdir(3) is, and always has been, MT-SAFE as long as only one thread is accessing the directory object returned by opendir(). World+Dog also says there is a potential buffer overflow in readdir_r(). World+Dog suggests that it is preferable to simply use readdir(). There's an implication that eventually readdir_r(3) will be removed from glibc. POSIX has, apparently deprecated it in the standard, or even removed it entirely. Over and above that, our source near the various uses of readdir(_r)(3) has a few unsafe uses of strcpy()+strcat(). (AFAIK nobody has looked at the readdir(3) implemenation in *BSD to see if the same is true on those platforms, and we can't be sure of MacOS even though we know it's based on *BSD.)

* features/bit-rot-stub: delete the link for bad object in quarantine directoryRaghavendra Bhat2015-12-161-0/+29
| | | | | | | | | | | | | | | | | | When the bad object is deleted (as of now manually from the backend itself), along with its gfid handle, the entry for the bad object in the quarantne directory is left as it is (it also can be removed manually though). But the next lookup of the object upon not finding it in the backend, sends forget on the in-memory inode. If the stale link for the gfid still exists in the quarantine directory, bir-rot-stub will unlink the entry in its forget or in the next failed lookup on that object with errno being ENOENT.
