2007-07-17Introduce is_owner_or_cap() to wrap CAP_FOWNER use with fsuid checkSatyam Sharma
Introduce is_owner_or_cap() macro in fs.h, and convert over relevant users to it. This is done because we want to avoid bugs in the future where we check for only effective fsuid of the current task against a file's owning uid, without simultaneously checking for CAP_FOWNER as well, thus violating its semantics. [ XFS uses special macros and structures, and in general looked ... untouchable, so we leave it alone -- but it has been looked over. ] The (current->fsuid != inode->i_uid) check in generic_permission() and exec_permission_lite() is left alone, because those operations are covered by CAP_DAC_OVERRIDE and CAP_DAC_READ_SEARCH. Similarly operations falling under the purview of CAP_CHOWN and CAP_LEASE are also left alone.

2006-11-02JFS: Remove redundant xattr permission checkingDave Kleikamp
The vfs handles most permissions for setting and retrieving xattrs. This patch removes a redundant and wrong check so that it won't override the correct behavior which is being fixed in the vfs. Signed-off-by: Dave Kleikamp <shaggy@austin.ibm.com>
2006-10-02JFS: White space cleanupDave Kleikamp
Removed trailing spaces & tabs, and spaces preceding tabs. Also a couple very minor comment cleanups. Signed-off-by: Dave Kleikamp <shaggy@austin.ibm.com> (cherry picked from f74156539964d7b3d5164fdf8848e6a682f75b97 commit)

2006-01-10[PATCH] move xattr permission checks into the VFSakpm@osdl.org
) From: Christoph Hellwig <hch@lst.de> The xattr code has rather complex permission checks because the rules are very different for different attribute namespaces. This patch moves as much as we can into the generic code. Currently all the major disk based filesystems duplicate these checks, while many minor filesystems or network filesystems lack some or all of them. To do this we need defines for the extended attribute names in common code, I moved them up from JFS which had the nicest defintions.

It turns out this is due to some inverted logic in xattr.c Signed-off-by: Dave Kleikamp <shaggy@austin.ibm.com>
2005-07-13JFS: Allow security.* xattrs to be set on symlinksDave Kleikamp
All of the different xattr namespaces have different rules. user.* and ACL's are not allowed on symlinks, and since these were the first xattrs implemented, I assumed there was no need to support xattrs on symlinks. This one-line patch should fix it. Signed-off-by: Dave Kleikamp <shaggy@austin.ibm.com>

2005-04-16Linux-2.6.12-rc2Linus Torvalds
Initial git repository build. I'm not bothering with the full history, even though we have it. We can create a separate "historical" git archive of that later if we want to, and in the meantime it's about 3.2GB when imported into git - space that would just make the early git days unnecessarily complicated, when we don't have a lot of good infrastructure for it. Let it rip!
