[PATCH v3 0/2] ovl: fix IS_APPEND() checks

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



Miklos,

This series fixes the append-only violations found by the new
xfstest overlay/030.

I addressed your comments on v2 and removed the patch to vfs_truncate()
because d_real() already takes cares of IS_APPEND().

Amir.

v3:
- address comments by Miklos
- discard unneeded patch to vfs_truncate()

v2:
- move open check to ovl_d_real()
- discard wrong patch to file_start_write() in ftruncate()

v1:
- fix checks in [f]truncate and vfs_open()

Amir Goldstein (2):
  vfs: ftruncate check IS_APPEND() on real upper inode
  ovl: check IS_APPEND() on real upper inode
