* [RFC] change get_real_filename implementation to use ENOATTR instead of ENOENTMichael Adam2019-06-261-2/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | get_real_filename is implemented as a virtual extended attribute to help Samba implement the case-insensitive but case preserving SMB protocol more efficiently. It is implemented as a getxattr call on the parent directory with the virtual key of "get_real_filename:<entryname>" by looking for a spelling with different case for the provided file/dir name (<entryname>) and returning this correct spelling as a result if the entry is found. Originally (05aaec645a6262d431486eb5ac7cd702646cfcfb), the implementation used the ENOENT errno to return the authoritative answer that <entryname> does not exist in any case folding. Now this implementation is actually a violation or misuse of the defined API for the getxattr call which returns ENOENT for the case that the dir that the call is made against does not exist and ENOATTR (or the synonym ENODATA) for the case that the xattr does not exist. This was not a problem until the gluster fuse-bridge was changed to do map ENOENT to ESTALE in 59629f1da9dca670d5dcc6425f7f89b3e96b46bf, after which we the getxattr call for get_real_filename returned an ESTALE instead of ENOENT breaking the expectation in Samba. It is an independent problem that ESTALE should not leak out to user space but is intended to trigger retries between fuse and gluster. But nevertheless, the semantics seem to be incorrect here and should be changed. This patch changes the implementation of the get_real_filename virtual xattr to correctly return ENOATTR instead of ENOENT if the file/directory being looked up is not found. The Samba glusterfs_fuse vfs module which takes advantage of the get_real_filename over a fuse mount will receive a corresponding change to map ENOATTR to ENOENT. Without this change, it will still work correctly, but the performance optimization for nonexisting files is lost. On the other hand side, this change removes the distinction between the old not-implemented case and the implemented case. So Samba changed to treat ENOATTR like ENOENT will not work correctly any more against old servers that don't implement get_real_filename. I.e. existing files will be reported as non-existing Change-Id: I971b427ab8410636d5d201157d9af70e0d075b67 fixes: bz#1722977 Signed-off-by: Michael Adam <obnox@samba.org>
* posix/ctime: Fix ctime upgrade issueKotresh HR2019-06-211-0/+21
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Problem: On a EC volume, during upgrade from the older version where ctime feature is not enabled(or not present) to the newer version where the ctime feature is available (enabled default), the self heal hangs and doesn't complete. Cause: The ctime feature has both client side code (utime) and server side code (posix). The feature is driven from client. Only if the client side sets the time in the frame, should the server side sets the time attributes in xattr. But posix setattr/fseattr was not doing that. When one of the server nodes is updated, since ctime is enabled by default, it starts setting xattr on setattr/fseattr on the updated node/brick. On a EC volume the first two updated nodes(bricks) are not a problem because there are 4 other bricks with consistent data. However once the third brick is updated, the new attribute(mdata xattr) will cause an inconsistency on metadata on 3 bricks, which prevents the file to be repaired. Fix: Don't create mdata xattr with utimes/utimensat system call. Only update if already present.

A previous more ambitious attempt failed because of *BSD plafrom (see https://review.gluster.org/#/c/glusterfs/+/21929/ ) Now trying a more conservative reduction. It does not solve all circular deps that we have, but it does reduce some of them. There is just too much to handle reasonably (dht-common.h includes dht-lock.h which includes dht-common.h ...), but it does reduce the overall number of lines of include we need to look at in the future to understand and fix the mess later one.

| | | | | | | | | | | | | | | | | The way delta_blocks is computed in shard is incorrect, when a file is truncated to a lower size. The accounting only considers change in size of the last of the truncated shards. FIX: Get the block-count of each shard just before an unlink at posix in xdata. Their summation plus the change in size of last shard (from an actual truncate) is used to compute delta_blocks which is used in the xattrop for size update.

| | | | | | | | | | | | | | | | nr_files is supposed to represent the number of files opened in posix. Present logic doesn't seem to handle anon-fds because of which the counts would always be wrong. I don't remember anyone using this value in debugging any problem probably because we always have 'ls -l /proc/<pid>/fd' which not only prints the fds that are active but also prints their paths. It also handles directories and anon-fds which actually opened the file. So removing this code instead of fixing the buggy logic to have the nr_files. fixes bz#1688106 Change-Id: Ibf8713fdfdc1ef094e08e6818152637206a54040 Signed-off-by: Pranith Kumar K <pkarampu@redhat.com>

It is expected to come in the upcoming release of linux-4.20 So, as of now, executing copy_file_range fop on a fused based filesystem results in fuse kernel module sending read on the source fd and write on the destination fd. Therefore a small gfapi based tool has been written to be able test the copy_file_range fop. This tool is similar (in functionality) to the example program given in copy_file_range man page. So, running regular copy_file_range on a fuse mount point and running gfapi based glfs-copy-file-range tool gives some idea about how fast, the copy_file_range (or reflink) can be. On the local machine this was the result obtained. mount -t glusterfs workstation:new /mnt/glusterfs [root@workstation ~]# cd /mnt/glusterfs/ [root@workstation glusterfs]# ls file [root@workstation glusterfs]# cd [root@workstation ~]# time /tmp/a.out /mnt/glusterfs/file /mnt/glusterfs/new real 0m6.495s user 0m0.000s sys 0m1.439s [root@workstation ~]# time glfs-copy-file-range $(hostname) new /tmp/glfs.log /file /rrr OPEN_SRC: opening /file is success OPEN_DST: opening /rrr is success FSTAT_SRC: fstat on /rrr is success copy_file_range successful real 0m0.309s user 0m0.039s sys 0m0.017s This tool needs following arguments 1) hostname 2) volume name 3) log file path 4) source file path (relative to the gluster volume root) 5) destination file path (relative to the gluster volume root) "glfs-copy-file-range <hostname> <volume> <log file path> <source> <destination>" - Added a testcase as well to run glfs-copy-file-range tool * io-stats changes to capture the fop for profiling * NOTE: - Added conditional check to see whether the copy_file_range syscall is available or not. If not, then return ENOSYS. - Added conditional check for kernel minor version in fuse_kernel.h and fuse-bridge while referring to copy_file_range.

* features/bitrot: compare the signature with proper lengthRaghavendra Bhat2018-12-031-7/+11
| | | | | | | | | | | | | | | | | | | | | * The scrubber was comparing the checksum of the file that it calculated (by reading the file) with the on disk signature (stored via xattr) wrongly. It was using strlen to calculate the signature, while the actual length of the signature is given by the brick. Just use the actual length that the brick provides instead of trying to calculate the signature length via strlen API. * In posix, gfid2path was using the same string that contains the list of all the xattrs of file to save the value of the gfid2path xattr as well. This causes confusion when gfid2path xattr is queried by scrubber for getting the actual path of a corrupted file. Use separate string to fetch the value of the xattr instead of the string that contains the list of xattrs.

| | | | | | | | | | | | | It seems there were quite a few unused enums (that in turn cause unndeeded memory allocation) in some xlators. I've removed them, hopefully not causing any damage.

* ctime: Enable ctime feature by defaultKotresh HR2018-11-111-1/+1
| | | | | | | | | | | | | | | | | | | | This patch does following. 1. Enable ctime feature by default. 2. Earlier, to enable the ctime feature, two options needed to be enabled a. gluster vol set <volname> utime on b. gluster vol set <volname> ctime on This is inconvenient from the usability point of view. Hence changed it to following single option a. gluster vol set <volname> ctime on fixes: bz#1624724 Change-Id: I04af0e5de1ea6126c58a06ba8a26e22f9f06344e Signed-off-by: Kotresh HR <khiremat@redhat.com>

* all: fix the format string exceptionsAmar Tumballi2018-11-051-3/+3
| | | | | | | | | | | | | | | | Currently, there are possibilities in few places, where a user-controlled (like filename, program parameter etc) string can be passed as 'fmt' for printf(), which can lead to segfault, if the user's string contains '%s', '%d' in it. While fixing it, makes sense to make the explicit check for such issues across the codebase, by making the format call properly.

* server: don't allow '/' in basenameAmar Tumballi2018-11-051-2/+2
| | | | | | | | | | | | | | | | Server stack needs to have all the sort of validation, assuming clients can be compromized. It is possible for a compromized client to send basenames with paths with '/', and with that create files without permission on server. By sanitizing the basename, and not allowing anything other than actual directory as the parent for any entry creation, we can mitigate the effects of clients not able to exploit the server.
