* Rework v_object lifecycle for vnodes.Konstantin Belousov2019-08-291-1/+0
| | | | | | | | | | | | | | | | | | | | | | | Current implementation of vnode_create_vobject() and vnode_destroy_vobject() is written so that it prepared to handle the vm object destruction for live vnode. Practically, no filesystems use this, except for some remnants that were present in UFS till today. One of the consequences of that model is that each filesystem must call vnode_destroy_vobject() in VOP_RECLAIM() or earlier, as result all of them get rid of the v_object in reclaim. Move the call to vnode_destroy_vobject() to vgonel() before VOP_RECLAIM(). This makes v_object stable: either the object is NULL, or it is valid vm object till the vnode reclamation. Remove code from vnode_create_vobject() to handle races with the parallel destruction.

* Remove "struct ucred*" argument from vtruncbufAlan Somers2019-05-241-2/+2
| | | | | | | | | | | | | | | vtruncbuf takes a "struct ucred*" argument. AFAICT, it's been unused ever since that function was first added in r34611. Remove it. Also, remove some "struct ucred" arguments from fuse and nfs functions that were only used by vtruncbuf.

* sys: further adoption of SPDX licensing ID tags.Pedro F. Giffuni2017-11-201-0/+2
| | | | | | | | | | | | | | | | | Mainly focus on files that use BSD 3-Clause license. The Software Package Data Exchange (SPDX) group provides a specification to make it easier for automated tools to detect and summarize well known opensource licenses. We are gradually adopting the specification, noting that the tags are considered only advisory and do not, in any way, superceed or replace the license texts. Special thanks to Wind River for providing access to "The Duke of Highlander" tool: an older (2014) run over FreeBSD tree was useful as a starting point. Notes: svn path=/head/; revision=326023

* ext2fs: add read-write support for Extended Attributes.Pedro F. Giffuni2017-05-031-0/+2
| | | | | | | | | | | | | | | | | Extended attributes and their particular implementation in linux are different from FreeBSD so in this case we have started diverging from the UFS EA implementation, which would be the natural reference. Depending on future progress implementing ACLs this approach may change but for now bring to the tree an implementation that is consistent and can be tested.

* Define ext2fs local types and use them.Pedro F. Giffuni2013-08-131-11/+11
| | | | | | | | | | | | | | | | | | | | | | | | | Add definitions for e2fs_daddr_t, e4fs_daddr_t in addition to the already existing e2fs_lbn_t and adjust them for ext4. Other than making the code more readable these changes should fix problems related to big filesystems. Setting the proper types can be tricky so the process was helped by looking at UFS. In our implementation, logical block numbers can be negative and the code depends on it. In ext2, block numbers are unsigned so it is convenient to keep e2fs_daddr_t unsigned and use the complete 32 bits. In the case of e4fs_daddr_t, while the value should be unsigned, for ext4 we only need to support 48 bits so preserving an extra bit from the sign is not an issue. While here also drop the ext2_setblock() prototype that was never used. Discussed with: mckusick, bde MFC after: 3 weeks Notes: svn path=/head/; revision=254283

* ext2fs: make some inode fields match the ext2 spec.Pedro F. Giffuni2013-01-221-2/+4
| | | | | | | | | | | | | | | | | Ext2fs uses unsigned fields in its dinode struct. FreeBSD can have negative values in some of those fields and the inode is meant to interact with the system so we have never respected the unsigned nature of most of those fields. Block numbers and the NFS generation number do not need to be signed so redefine them as unsigned to better match the on-disk information. MFC after: 1 week Notes: svn path=/head/; revision=245820

This merger is possible by assigning the IO_ flags to the low sixteen bits and the BA_ flags the high sixteen bits. - 105422: Fix a file-rewrite performance case. - 129545: Implement IO_INVAL in VOP_WRITE() by marking the buffer as "no cache". - Readd the DOINGASYNC() macro and use it to control asynchronous writes. Change i-node updates to honor DOINGASYNC() instead of always being synchronous. - Use a PRIV_VFS_RETAINSUGID check instead of checking cr_uid against 0 directly when deciding whether or not to clear suid and sgid bits.
