2016-02-25Fix directory hardlinks from deleted directoriesDavid Woodhouse1-1/+5
When a directory is deleted, we don't take too much care about killing off all the dirents that belong to it — on the basis that on remount, the scan will conclude that the directory is dead anyway. This doesn't work though, when the deleted directory contained a child directory which was moved *out*. In the early stages of the fs build we can then end up with an apparent hard link, with the child directory appearing both in its true location, and as a child of the original directory which are this stage of the mount process we don't *yet* know is defunct. To resolve this, take out the early special-casing of the "directories shall not have hard links" rule in jffs2_build_inode_pass1(), and let the normal nlink processing happen for directories as well as other inodes. Then later in the build process we can set ic->pino_nlink to the parent inode#, as is required for directories during normal operaton, instead of the nlink. And complain only *then* about hard links which are still in evidence even after killing off all the unreachable paths.

2011-02-01fs/vfs/security: pass last path component to LSM on inode creationEric Paris1-1/+1
SELinux would like to implement a new labeling behavior of newly created inodes. We currently label new inodes based on the parent and the creating process. This new behavior would also take into account the name of the new object when deciding the new label. This is not the (supposed) full path, just the last component of the path. This is very useful because creating /etc/shadow is different than creating /etc/passwd but the kernel hooks are unable to differentiate these operations. We currently require that userspace realize it is doing some difficult operation like that and than userspace jumps through SELinux hoops to get things set up correctly. This patch does not implement new behavior, that is obviously contained in a seperate SELinux patch, but it does pass the needed name down to the correct LSM hook. If no such name exists it is fine to pass NULL. Signed-off-by: Eric Paris <eparis@redhat.com>
2010-10-25jffs2: Dynamically choose inocache hash sizeDaniel Drake1-1/+2
When JFFS2 is used for large volumes, the mount times are quite long. Increasing the hash size provides a significant speed boost on the OLPC XO-1 laptop. Add logic that dynamically selects a hash size based on the size of the medium. A 64mb medium will result in a hash size of 128, and a 512mb medium will result in a hash size of 1024.

2007-04-25[JFFS2] Improve read_inode memory usage, v2.David Woodhouse1-2/+23
We originally used to read every node and allocate a jffs2_tmp_dnode_info structure for each, before processing them in (reverse) version order and discarding the ones which are obsoleted by later nodes. With huge logfiles, this behaviour caused memory problems. For example, a file involved in OLPC trac #1292 has 1822391 nodes, and would cause the XO machine to run out of memory during the first stage of read_inode(). Instead of just inserting nodes into a tree in version order as we find them, we now put them into a tree in order of their offset within the file, which allows us to immediately discard nodes which are completely obsoleted. We don't use a full tree with 'fragments' pointing to the real data structure, as we do in the normal fragtree. We sort only on the start address, and add an 'overlapped' flag to the tmp_dnode_info to indicate that the node in question is (partially) overlapped by another. When the scan is complete, we start at the end of the file, adding each node to a real fragtree as before. Where the node is non-overlapped, we just add it (it doesn't matter that it's not the latest version; there is no overlap). When the node at the end of the tree _is_ overlapped, we sort it and all its overlapping nodes into version order and then add them to the fragtree in that order. This 'early discard' reduces the peak allocation of tmp_dnode_info structures from 1.8M to a mere 62872 (3.5%) in the degenerate case referenced above. This version of the patch also correctly rememembers the highest node version# seen for an inode when it's scanned. Signed-off-by: David Woodhouse <dwmw2@infradead.org>

Device node major/minor numbers are just stored in the payload of a single data node. Just extend that to 4 bytes and use new_encode_dev() for it. We only use the 4-byte format if we _need_ to, if !old_valid_dev(foo). This preserves backwards compatibility with older code as much as possible. If we do make devices with major or minor numbers above 255, and then mount the file system with the old code, it'll just read the first two bytes and get the numbers wrong. If it comes to garbage-collect it, it'll then write back those wrong numbers. But that's about the best we can expect. Signed-off-by: David Woodhouse <dwmw2@infradead.org>

2006-05-13[JFFS2][XATTR] XATTR support on JFFS2 (version. 5)KaiGai Kohei1-1/+20
This attached patches provide xattr support including POSIX-ACL and SELinux support on JFFS2 (version.5). There are some significant differences from previous version posted at last December. The biggest change is addition of EBS(Erase Block Summary) support. Currently, both kernel and usermode utility (sumtool) can recognize xattr nodes which have JFFS2_NODETYPE_XATTR/_XREF nodetype. In addition, some bugs are fixed. - A potential race condition was fixed. - Unexpected fail when updating a xattr by same name/value pair was fixed. - A bug when removing xattr name/value pair was fixed. The fundamental structures (such as using two new nodetypes and exclusion mechanism by rwsem) are unchanged. But most of implementation were reviewed and updated if necessary. Espacially, we had to change several internal implementations related to load_xattr_datum() to avoid a potential race condition.

2005-11-06[JFFS2] Add erase block summary support (mount time improvement)Ferenc Havasi1-3/+10
The goal of summary is to speed up the mount time. Erase block summary (EBS) stores summary information at the end of every (closed) erase block. It is no longer necessary to scan all nodes separetly (and read all pages of them) just read this "small" summary, where every information is stored which is needed at mount time. This summary information is stored in a JFFS2_FEATURE_RWCOMPAT_DELETE. During the mount process if there is no summary info the orignal scan process will be executed. EBS works with NAND and NOR flashes, too. There is a user space tool called sumtool to generate this summary information for a JFFS2 image.
