commit 6769a23697f17f9bf9365ca8ed62fe37e361a05a upstream.

The "instance" variable needs to be signed for the error handling to work.

commit 255547c6bb8940a97eea94ef9d464ea5967763fb upstream.

This adds sanity checks for ocfs2_dir_entry to make sure all members of ocfs2_dir_entry don't stray beyond valid memory region.

This adds sanity checks for ff offset. There is a check on rt->first_free at first, but walking through by ff without any check. If the second ff is a large offset. We may encounter an out-of-bound read.

commit 4ae4837871ee8c8b055cf8131f65d31ee4208fa0 upstream.

For Gen-1 targets like IPQ6018, it is seen that stressing out the controller in host mode results in HC died error:

xhci-hcd.12.auto: xHCI host not responding to stop endpoint command xhci-hcd.12.auto: xHCI host controller not responding, assume dead xhci-hcd.12.auto: HC died; cleaning up

And at this instant only restarting the host mode fixes it. Disable SuperSpeed instance in park mode for IPQ6018 to mitigate this issue.

commit df9f278239046719c91aeb59ec0afb1a99ee8b2b upstream.

During the transaction commit path, at create_pending_snapshot(), there is no need to BUG_ON() in case we fail to get a dir index for the snapshot in the parent directory. This should fail very rarely because the parent inode should be loaded in memory already, with the respective delayed inode created and the parent inode's index_cnt field already initialized.

However if it fails, it may be -ENOMEM like the comment at create_pending_snapshot() says or any error returned by btrfs_search_slot() through btrfs_set_inode_index_count(), which can be pretty much anything such as -EIO or -EUCLEAN for example. So the comment is not correct when it says it can only be -ENOMEM.

However doing a BUG_ON() here is overkill, since we can instead abort the transaction and return the error. Note that any error returned by create_pending_snapshot() will eventually result in a transaction abort at cleanup_transaction(), called from btrfs_commit_transaction(), but we can explicitly abort the transaction at this point instead so that we get a stack trace to tell us that the call to btrfs_set_inode_index() failed.

So just abort the transaction and return in case btrfs_set_inode_index() returned an error at create_pending_snapshot().
