ceph_getattr() return zero dev ID for head inodes and set dev ID to snapid directly for snaphost inodes. This is not good because userspace utilities may consider device ID of 0 as invalid, snapid may conflict with other device's ID. This patch introduces "snapids to anonymous bdev IDs" map. we create a new mapping when we see a snapid for the first time. we trim unused mapping after it is ilde for 5 minutes.

ceph_setattr() finally calls vfs function inode_newsize_ok() to do offset validation and that is based on sb->s_maxbytes. Because we set sb->s_maxbytes to MAX_LFS_FILESIZE to through VFS check and do proper offset validation in cephfs level, we need adding proper offset validation before calling inode_newsize_ok().

Since the vfs structures are all using timespec64, we can now change the internal representation, using ceph_encode_timespec64 and ceph_decode_timespec64. In case of ceph_aux_inode however, we need to avoid doing a memcmp() on uninitialized padding data, so the members of the i_mtime field get copied individually into 64-bit integers.

struct timespec is not y2038 safe. Transition vfs to use y2038 safe struct timespec64 instead. The change was made with the help of the following cocinelle script. This catches about 80% of the changes. All the header file and logic changes are included in the first 5 rules. The rest are trivial substitutions. I avoid changing any of the function signatures or any other filesystem specific data structures to keep the patch simple for review. The script can be a little shorter by combining different cases.

Currently, calling stat on a cephfs directory returns 1 for st_nlink. This behaviour has recently changed in the fuse client, as some applications seem to expect this value to be either 0 (if it's unlinked) or 2 + number of subdirectories. This behaviour was changed in the fuse client with commit 67c7e4619188 ("client: use common interp of st_nlink for dirs"). This patch modifies the kernel client to have a similar behaviour.

This patch adds the infrastructure required to support cephfs quotas as it is currently implemented in the ceph fuse client. Cephfs quotas can be set on any directory, and can restrict the number of bytes or the number of files stored beneath that point in the directory hierarchy. Quotas are set using the extended attributes 'ceph.quota.max_files' and 'ceph.quota.max_bytes', and can be removed by setting these attributes to '0'.

Readdir cache keeps array of dentry pointers in page cache. If any dentry in readdir cache gets pruned, ceph_d_prune() disables readdir cache for later readdir syscall. The problem is that ceph_d_prune() ignores unhashed dentry. Ideally MDS should have already revoked CEPH_CAP_FILE_SHARED (which also disables readdir cache) when dentry gets unhashed. But if it is somehow MDS does not properly revoke CEPH_CAP_FILE_SHARED and the unhashed dentry gets pruned later, ceph_d_prune() will not disable readdir cache, later readdir may reference invalid dentry pointer. The fix is make ceph_d_prune() do extra check for unhashed dentry. Disable readdir cache if the unhashed dentry is still referenced by readdir cache. Another fix in this patch is handle d_splice_alias(). If a dentry gets spliced into new parent dentry, treat it as if it was pruned (call ceph_d_prune() for it).

Many source files in the tree are missing licensing information, which makes it harder for compliance tools to determine the correct license. By default all files without license information are under the default license of the kernel, which is GPL version 2. Update the files which contain no license information with the 'GPL-2.0' SPDX license identifier. The SPDX identifier is a legally binding shorthand, which can be used instead of the full boiler plate text. This patch is based on work done by Thomas Gleixner and Kate Stewart and Philippe Ombredanne. How this work was done: Patches were generated and checked against linux-4.14-rc6 for a subset of the use cases: - file had no licensing information it it. - file was a */uapi/* one with no licensing information in it, - file was a */uapi/* one with existing licensing information, Further patches will be generated in subsequent months to fix up cases where non-standard license headers were used, and references to license had to be inferred by heuristics based on keywords. The analysis to determine which SPDX License Identifier to be applied to a file was done in a spreadsheet of side by side results from of the output of two independent scanners (ScanCode & Windriver) producing SPDX tag:value files created by Philippe Ombredanne. Philippe prepared the base worksheet, and did an initial spot review of a few 1000 files. The 4.13 kernel was the starting point of the analysis with 60,537 files assessed. Kate Stewart did a file by file comparison of the scanner results in the spreadsheet to determine which SPDX license identifier(s) to be applied to the file. She confirmed any determination that was not immediately clear with lawyers working with the Linux Foundation. Criteria used to select files for SPDX license identifier tagging was: - Files considered eligible had to be source code files. - Make and config files were included as candidates if they contained >5 lines of source - File already had some variant of a license header in it (even if <5 lines). All documentation files were explicitly excluded. The following heuristics were used to determine which SPDX license identifiers to apply. - when both scanners couldn't find any license traces, file was considered to have no license information in it, and the top level COPYING file license applied. For non */uapi/* files that summary was: SPDX license identifier # files ---------------------------------------------------|------- GPL-2.0 11139 and resulted in the first patch in this series. If that file was a */uapi/* path one, it was "GPL-2.0 WITH Linux-syscall-note" otherwise it was "GPL-2.0". Results of that was: SPDX license identifier # files ---------------------------------------------------|------- GPL-2.0 WITH Linux-syscall-note 930 and resulted in the second patch in this series. - if a file had some form of licensing information in it, and was one of the */uapi/* ones, it was denoted with the Linux-syscall-note if any GPL family license was found in the file or had no licensing in it (per prior point). Results summary: SPDX license identifier # files ---------------------------------------------------|------ GPL-2.0 WITH Linux-syscall-note 270 GPL-2.0+ WITH Linux-syscall-note 169 ((GPL-2.0 WITH Linux-syscall-note) OR BSD-2-Clause) 21 ((GPL-2.0 WITH Linux-syscall-note) OR BSD-3-Clause) 17 LGPL-2.1+ WITH Linux-syscall-note 15 GPL-1.0+ WITH Linux-syscall-note 14 ((GPL-2.0+ WITH Linux-syscall-note) OR BSD-3-Clause) 5 LGPL-2.0+ WITH Linux-syscall-note 4 LGPL-2.1 WITH Linux-syscall-note 3 ((GPL-2.0 WITH Linux-syscall-note) OR MIT) 3 ((GPL-2.0 WITH Linux-syscall-note) AND MIT) 1 and that resulted in the third patch in this series. - when the two scanners agreed on the detected license(s), that became the concluded license(s). - when there was disagreement between the two scanners (one detected a license but the other didn't, or they both detected different licenses) a manual inspection of the file occurred. - In most cases a manual inspection of the information in the file resulted in a clear resolution of the license that should apply (and which scanner probably needed to revisit its heuristics). - When it was not immediately clear, the license identifier was confirmed with lawyers working with the Linux Foundation. - If there was any question as to the appropriate license identifier, the file was flagged for further research and to be revisited later in time. In total, over 70 hours of logged manual review was done on the spreadsheet to determine the SPDX license identifiers to apply to the source files by Kate, Philippe, Thomas and, in some cases, confirmation by lawyers working with the Linux Foundation. Kate also obtained a third independent scan of the 4.13 code base from FOSSology, and compared selected files where the other two scanners disagreed against that SPDX file, to see if there was new insights. The Windriver scanner is based on an older version of FOSSology in part, so they are related. Thomas did random spot checks in about 500 files from the spreadsheets for the uapi headers and agreed with SPDX license identifier in the files he inspected. For the non-uapi files Thomas did random spot checks in about 15000 files. In initial set of patches against 4.14-rc6, 3 files were found to have copy/paste license identifier errors, and have been fixed to reflect the correct identifier. Additionally Philippe spent 10 hours this week doing a detailed manual inspection and review of the 12,461 patched files from the initial patch version early this week with: - a full scancode scan run, collecting the matched texts, detected license ids and scores - reviewing anything where there was a license detected (about 500+ files) to ensure that the applied SPDX license was correct - reviewing anything where there was no detection but the patch license was not GPL-2.0 WITH Linux-syscall-note to ensure that the applied SPDX license was correct This produced a worksheet with 20 files needing minor correction. This worksheet was then exported into 3 different .csv files for the different types of files to be modified. These .csv files were then reviewed by Greg. Thomas wrote a script to parse the csv files and add the proper SPDX tag to the file, in the format that the file expected. This script was further refined by Greg based on the output to detect more types of files automatically and to distinguish between header and source .c files (which need different comment types.) Finally Greg ran the script using the .csv files to generate the patches.
