2006-06-27[JFFS2][XATTR] Fix memory leak with jffs2_xattr_refKaiGai Kohei1-0/+3
If xattr_ref is associated with an orphan inode_cache on filesystem mounting, those xattr_refs are not released even if this inode_cache is released. This patch enables to call jffs2_xattr_delete_inode() for such a irregular inode_cachde too. Signed-off-by: KaiGai Kohei <kaigai@ak.jp.nec.com> Signed-off-by: David Woodhouse <dwmw2@infradead.org>

2006-05-26[JFFS2] Switch to using an array of jffs2_raw_node_refs instead of a list.David Woodhouse1-46/+47
This allows us to drop another pointer from the struct jffs2_raw_node_ref, shrinking it to 8 bytes on 32-bit machines (if the TEST_TOTLEN) paranoia check is turned off, which will be committed soon). Signed-off-by: David Woodhouse <dwmw2@infradead.org>

2006-05-24[JFFS2] Reduce visibility of raw_node_ref to upper layers of JFFS2 code.David Woodhouse1-18/+33
As the first step towards eliminating the ref->next_phys member and saving memory by using an _array_ of struct jffs2_raw_node_ref per eraseblock, stop the write functions from allocating their own refs; have them just _reserve_ the appropriate number instead. Then jffs2_link_node_ref() can just fill them in. Use a linked list of pre-allocated refs in the superblock, for now. Once we switch to an array, it'll just be a case of extending that array.

2006-05-22[JFFS2] Extend jffs2_link_node_ref() to link into per-inode list too.David Woodhouse1-3/+10
Let's avoid the potential for forgetting to set ref->next_in_ino, by doing it within jffs2_link_node_ref() instead. This highlights the ugliness of what we're currently doing with xattr_datum and xattr_ref structures -- we should find a nicer way of dealing with that.

2006-05-22[JFFS2] Fix accounting error in jffs2_link_node_ref()David Woodhouse1-1/+1
When filing REF_OBSOLETE nodes, we'd add their size to the global 'dirty_size' count, but then to the eraseblock's 'used_size' count. That's not clever. Signed-off-by: David Woodhouse <dwmw2@infradead.org>
2006-05-21[JFFS2] Finally eliminate __totlen field from struct jffs2_raw_node_refDavid Woodhouse1-7/+108
Well, almost. We'll actually keep a 'TEST_TOTLEN' macro set for now, and keep doing some paranoia checks to make sure it's all working correctly. But if TEST_TOTLEN is unset, the size of struct jffs2_raw_node_ref drops from 16 bytes to 12 on 32-bit machines. That's a saving of about half a megabyte of memory on the OLPC prototype board, with 125K or so nodes in its 512MiB of flash. Signed-off-by: David Woodhouse <dwmw2@infradead.org>
2006-05-21[JFFS2] Introduce jffs2_scan_dirty_space() function.David Woodhouse1-0/+11
To eliminate the __totlen field from struct jffs2_raw_node_ref, we need to allocate nodes for dirty space instead of just tweaking the accounting data. Introduce jffs2_scan_dirty_space() in preparation for that. Signed-off-by: David Woodhouse <dwmw2@infradead.org>
2006-05-20[JFFS2] Introduce jffs2_link_node_ref() function to reduce code duplicationDavid Woodhouse1-0/+34
The same sequence of code was repeated in many places, to add a new struct jffs2_raw_node_ref to an eraseblock and adjust the space accounting accordingly. Move it out-of-line. Signed-off-by: David Woodhouse <dwmw2@infradead.org>

2006-05-15[JFFS2] Fix printk format in some error messages.Andrew Morton1-2/+2
fs/jffs2/nodelist.c: In function `check_node_data': fs/jffs2/nodelist.c:441: warning: unsigned int format, different type arg (arg 4) fs/jffs2/nodelist.c:464: warning: int format, different type arg (arg 5) Modified from Andrew's original fix because while his terminal may indeed only have eighty columns, mine only has _TWENTYFOUR_ lines. So the cosmetic fluff is perfectly OK out past column 80 where it was -- the casual reader doesn't _care_ about anything more than the fact that it goes 'if (foo) JFFS2_WARNING...', and there's no point wasting a whole line to display the tail end of the printk which nobody actually cares about.

2006-05-13[JFFS2][XATTR] XATTR support on JFFS2 (version. 5)KaiGai Kohei1-0/+1
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.

Fix some bugs in mtd/jffs2 on 64bit platform. The MEMGETBADBLOCK/MEMSETBADBLOCK ioctl are not listed in compat_ioctl.h.

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!
