* [JFFS2] Introduce dbg_readinode2 log level, use it to shut read_dnode() upDavid Woodhouse2008-04-23
| | | | | | | We haven't seen bugs in this for a while now, since the rewrite. No need to be _quite_ so verbose... Signed-off-by: David Woodhouse <dwmw2@infradead.org>
* [JFFS2] Fix jffs2_reserve_space() when all blocks are pending erasure.David Woodhouse2008-04-23
| | | | | | | | | | | | | | | When _all_ the blocks were on the erase_pending_list, we could't find a block to GC from but there was no _actually_ free space, and jffs2_reserve_space() would get a little unhappy. Handle this case by returning -EAGAIN from jffs2_garbage_collect_pass(). There are two callers of that function -- jffs2_flush_wbuf_gc(), which will interpret it as an error and flush the writebuffer by other means, and jffs2_reserve_space(), which we modify to respond to -EAGAIN with an immediate call to jffs2_erase_pending_blocks() and another run round the loop.

* [JFFS2] Add paranoia debugging for superblock countsDavid Woodhouse2008-04-22
| | | | | | | | | | | | | The problem fixed in commit 014b164e1392a166fe96e003d2f0e7ad2e2a0bb7 (space leak with in-band cleanmarkers) would have been caught a lot quicker if our paranoid debugging mode had included adding up the size counts from all the eraseblocks and comparing the totals with the counts in the superblock. Add that. Make jffs2_mark_erased_block() file the newly-erased block on the free_list before calling the debug function, to make it happy. Signed-off-by: David Woodhouse <dwmw2@infradead.org>
* [JFFS2] Fix free space leak with in-band cleanmarkersDavid Woodhouse2008-04-22
| | | | | | | | | | | | | | | | | | | | | We were accounting for the cleanmarker by calling jffs2_link_node_ref() (without locking!), which adjusted both superblock and per-eraseblock accounting, subtracting the size of the cleanmarker from {jeb,c}->free_size and adding it to {jeb,c}->used_size. But only _then_ were we adding the size of the newly-erased block back to the superblock counts, and we were adding each of jeb->{free,used}_size to the corresponding superblock counts. Thus, the size of the cleanmarker was effectively subtracted from the superblock's free_size _twice_. Fix this, by always adding a full eraseblock size to c->free_size when we've erased a block. And call jffs2_link_node_ref() under the proper lock, while we're at it. Thanks to Alexander Yurchenko and/or Damir Shayhutdinov for (almost) pinpointing the problem.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | write_begin This fixes a regression introduced in commit 205c109a7a96d9a3d8ffe64c4068b70811fef5e8 when switching to write_begin/write_end operations in JFFS2. The page offset is miscalculated, leading to corruption of the fragment lists and subsequently to memory corruption and panics. [ Side note: the bug is a fairly direct result of the naming. Nick was likely misled by the use of "offs", since we tend to use the notion of "offset" not as an absolute position, but as an offset _within_ a page or allocation. Alternatively, a "pgoff_t" is a page index, but not a byte offset - our VM naming can be a bit confusing. So in this case, a VM person would likely have called this a "pos", not an "offs", or perhaps talked about byte offsets rather than page offsets (since it's counted in bytes, not pages). - Linus ] Signed-off-by: Alexey Korolev <akorolev@infradead.org> Signed-off-by: Vasiliy Leonenko <vasiliy.leonenko@mail.ru> Signed-off-by: David Woodhouse <dwmw2@infradead.org> Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>

Removing them immediately from the f->dents list, however, screws up handling of f_pos within a directory -- because the offset is equivalent to the number of entries through the list we are, and the existence of deletion dirents served to provide 'placeholders' for unlinked entries. Now, 'rm -r' doesn't even manage to unlink everything in the directory. Revert to keeping 'deletion' dirents in the list, at least in memory even though we no longer write anything to the medium.

* [JFFS2] Tidy up fix for ACL/permissions problem.KaiGai Kohei2007-10-20
| | | | | | | | | | | | | | | | | | | | | | | | | | [In commit 9ed437c50d89eabae763dd422579f73fdebf288d we fixed a problem with standard permissions on newly-created inodes, when POSIX ACLs are enabled. This cleans it up...] The attached patch separate jffs2_init_acl() into two parts. The one is jffs2_init_acl_pre() called from jffs2_new_inode(). It compute ACL oriented inode->i_mode bits, and allocate in-memory ACL objects associated with the new inode just before when inode meta infomation is written to the medium. The other is jffs2_init_acl_post() called from jffs2_symlink(), jffs2_mkdir(), jffs2_mknod() and jffs2_do_create(). It actually writes in-memory ACL objects into the medium next to the success of writing meta-information. In the current implementation, we have to write a same inode meta infomation twice when inode->i_mode is updated by the default ACL. However, we can avoid the behavior by putting an updated i_mode before it is written at first, as jffs2_init_acl_pre() doing.

I didn't have a great look down the call chains, but this appears to fixes 7 possible use-before uptodate in hfs, 2 in hfsplus, 1 in jfs, a few in ecryptfs, 1 in jffs2, and a possible cleared data overwritten with readpage in block2mtd. All depending on whether the filler is async and/or can return with a !uptodate page. It introduced a wait to read_cache_page, as well as a read_cache_page_async function equivalent to the old read_cache_page without any callers. Switching jffs2_gc_fetch_page to read_cache_page_async for the old behavior makes the deadlocks go away, but maybe reintroduces the use-before-uptodate problem?
