* Linux 6.3 compat: idmapped mount API changesyouzhongyang2023-04-101-17/+39
| | | | | | | | | Linux kernel 6.3 changed a bunch of APIs to use the dedicated idmap type for mounts (struct mnt_idmap), we need to detect these changes and make zfs work with the new APIs.

* zfs_rename: support RENAME_* flagsAleksa Sarai2022-10-281-8/+63
| | | | | | | | | | | | | | | | | | | | | | Implement support for Linux's RENAME_* flags (for renameat2). Aside from being quite useful for userspace (providing race-free ways to exchange paths and implement mv --no-clobber), they are used by overlayfs and are thus required in order to use overlayfs-on-ZFS. In order for us to represent the new renameat2(2) flags in the ZIL, we create two new transaction types for the two flags which need transactional-level support (RENAME_EXCHANGE and RENAME_WHITEOUT). RENAME_NOREPLACE does not need any ZIL support because we know that if the operation succeeded before creating the ZIL entry, there was no file to be clobbered and thus it can be treated as a regular TX_RENAME.

* Fixing m4 iops rename checkBrian Atkinson2021-04-011-0/+1
| | | | | | | | | The configure check for iops->rename wanting flags was missing the AC_MSG_CHECKING() so it would just print yes without saying what was being checked. Reviewed-by: Brian Behlendorf <[email protected]> Signed-off-by: Brian Atkinson <[email protected]> Closes #11825
* Linux 5.12 compat: idmapped mountsColeman Kane2021-03-191-12/+38
| | | | | | | | | | | | | | | | In Linux 5.12, the filesystem API was modified to support ipmapped mounts by adding a "struct user_namespace *" parameter to a number functions and VFS handlers. This change adds the needed autoconf macros to detect the new interfaces and updates the code appropriately. This change does not add support for idmapped mounts, instead it preserves the existing behavior by passing the initial user namespace where needed. A subsequent commit will be required to add support for idmapped mounted.

* Perform KABI checks in parallelBrian Behlendorf2019-10-011-6/+10
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Reduce the time required for ./configure to perform the needed KABI checks by allowing kbuild to compile multiple test cases in parallel. This was accomplished by splitting each test's source code from the logic handling whether that code could be compiled or not. By introducing this split it's possible to minimize the number of times kbuild needs to be invoked. As importantly, it means all of the tests can be built in parallel. This does require a little extra care since we expect some tests to fail, so the --keep-going (-k) option must be provided otherwise some tests may not get compiled. Furthermore, since a failure during the kbuild modpost phase will result in an early exit; the final linking phase is limited to tests which passed the initial compilation and produced an object file. Once everything has been built the configure script proceeds as previously. The only significant difference is that it now merely needs to test for the existence of a .ko file to determine the result of a given test. This vastly speeds up the entire process. New test cases should use ZFS_LINUX_TEST_SRC to declare their test source code and ZFS_LINUX_TEST_RESULT to check the result. All of the existing kernel-*.m4 files have been updated accordingly, see config/kernel-current-time.m4 for a basic example. The legacy ZFS_LINUX_TRY_COMPILE macro has been kept to handle special cases but it's use is not encouraged. master (secs) patched (secs) ------------- ---------------- autogen.sh 61 68 configure 137 24 (~17% of current run time) make -j $(nproc) 44 44 make rpms 287 150 Reviewed-by: Tony Hutter <[email protected]> Signed-off-by: Brian Behlendorf <[email protected]> Closes #8547 Closes #9132 Closes #9341
