reiserfs: Don't clear SGID when inheriting ACLs

2017-07-27T22:08:08+00:00

commit 6883cd7f68245e43e91e5ee583b7550abf14523f upstream.

When new directory 'DIR1' is created in a directory 'DIR0' with SGID bit
set, DIR1 is expected to have SGID bit set (and owning group equal to
the owning group of 'DIR0'). However when 'DIR0' also has some default
ACLs that 'DIR1' inherits, setting these ACLs will result in SGID bit on
'DIR1' to get cleared if user is not member of the owning group.

Fix the problem by moving posix_acl_update_mode() out of
__reiserfs_set_acl() into reiserfs_set_acl(). That way the function will
not be called when inheriting ACLs which is what we want as it prevents
SGID bit clearing and the mode has been properly set by
posix_acl_create() anyway.

fs: add i_blocksize()

2017-06-14T13:06:00+00:00

commit 93407472a21b82f39c955ea7787e5bc7da100642 upstream.

Replace all 1 << inode->i_blkbits and (1 << inode->i_blkbits) in fs
branch.

This patch also fixes multiple checkpatch warnings: WARNING: Prefer
'unsigned int' to bare use of 'unsigned'

Thanks to Andrew Morton for suggesting more appropriate function instead
of macro.

fs: Replace CURRENT_TIME_SEC with current_time() for inode timestamps

2016-09-28T01:06:22+00:00

CURRENT_TIME_SEC is not y2038 safe. current_time() will
be transitioned to use 64 bit time along with vfs in a
separate patch.
There is no plan to transistion CURRENT_TIME_SEC to use
y2038 safe time interfaces.

current_time() will also be extended to use superblock
range checking parameters when range checking is introduced.

This works because alloc_super() fills in the the s_time_gran
in super block to NSEC_PER_SEC.

fs: support RENAME_NOREPLACE for local filesystems

2016-09-27T09:03:57+00:00

This is trivial to do:

 - add flags argument to foo_rename()
 - check if flags doesn't have any other than RENAME_NOREPLACE
 - assign foo_rename() to .rename2 instead of .rename

Filesystems converted:

affs, bfs, exofs, ext2, hfs, hfsplus, jffs2, jfs, logfs, minix, msdos,
nilfs2, omfs, reiserfs, sysvfs, ubifs, udf, ufs, vfat.

fs: Give dentry to inode_change_ok() instead of inode

2016-09-22T08:56:19+00:00

inode_change_ok() will be resposible for clearing capabilities and IMA
extended attributes and as such will need dentry. Give it as an argument
to inode_change_ok() instead of an inode. Also rename inode_change_ok()
to setattr_prepare() to better relect that it does also some
modifications in addition to checks.
