2017-04-18Btrfs: add file item tracepointsLiu Bo
While debugging truncate problems, I found that these tracepoints could help us quickly know what went wrong. Two sets of tracepoints are created to track regular/prealloc file item and inline file item respectively, I put inline as a separate one since what inline file items cares about are way less than the regular one. This adds four tracepoints: - btrfs_get_extent_show_fi_regular - btrfs_get_extent_show_fi_inline - btrfs_truncate_show_fi_regular - btrfs_truncate_show_fi_inline Cc: David Sterba <dsterba@suse.cz> Signed-off-by: Liu Bo <bo.li.liu@oracle.com> Reviewed-by: David Sterba <dsterba@suse.com> [ formatting adjustments ] Signed-off-by: David Sterba <dsterba@suse.com>

If your filesystem has, eg, data:raid0 metadata:raid1, and you run "btrfs balance -dconvert=raid1", the meta.target field will be uninitialized. That's otherwise ok, as it's unused except for this warning. Thus, let's use the existing set of raid levels for the comparison. As a side effect, non-convert balances will now nag about data>metadata.

2017-04-17cifs: Do not send echoes before Negotiate is completeSachin Prabhu
commit 4fcd1813e640 ("Fix reconnect to not defer smb3 session reconnect long after socket reconnect") added support for Negotiate requests to be initiated by echo calls. To avoid delays in calling echo after a reconnect, I added the patch introduced by the commit b8c600120fc8 ("Call echo service immediately after socket reconnect"). This has however caused a regression with cifs shares which do not have support for echo calls to trigger Negotiate requests. On connections which need to call Negotiation, the echo calls trigger an error which triggers a reconnect which in turn triggers another echo call. This results in a loop which is only broken when an operation is performed on the cifs share. For an idle share, it can DOS a server. The patch uses the smb_operation can_echo() for cifs so that it is called only if connection has been already been setup. kernel bz: 194531 Signed-off-by: Sachin Prabhu <sprabhu@redhat.com> Tested-by: Jonathan Liu <net147@gmail.com> Acked-by: Pavel Shilovsky <pshilov@microsoft.com> CC: Stable <stable@vger.kernel.org> Signed-off-by: Steve French <smfrench@gmail.com>

2017-04-17Remove compat_sys_getdents64()Al Viro
Unlike normal compat syscall variants, it is needed only for biarch architectures that have different alignement requirements for u64 in 32bit and 64bit ABI *and* have __put_user() that won't handle a store of 64bit value at 32bit-aligned address. We used to have one such (ia64), but its biarch support has been gone since 2010 (after being broken in 2008, which went unnoticed since nobody had been using it). It had escaped removal at the same time only because back in 2004 a patch that switched several syscalls on amd64 from private wrappers to generic compat ones had switched to use of compat_sys_getdents64(), which hadn't needed (or used) a compat wrapper on amd64. Let's bury it - it's at least 7 years overdue. Signed-off-by: Al Viro <viro@zeniv.linux.org.uk>

2017-04-15vfs: don't do RCU lookup of empty pathnamesLinus Torvalds
Normal pathname lookup doesn't allow empty pathnames, but using AT_EMPTY_PATH (with name_to_handle_at() or fstatat(), for example) you can trigger an empty pathname lookup. And not only is the RCU lookup in that case entirely unnecessary (because we'll obviously immediately finalize the end result), it is actively wrong. Why? An empth path is a special case that will return the original 'dirfd' dentry - and that dentry may not actually be RCU-free'd, resulting in a potential use-after-free if we were to initialize the path lazily under the RCU read lock and depend on complete_walk() finalizing the dentry.

2017-04-13hugetlbfs: fix offset overflow in hugetlbfs mmapMike Kravetz
If mmap() maps a file, it can be passed an offset into the file at which the mapping is to start. Offset could be a negative value when represented as a loff_t. The offset plus length will be used to update the file size (i_size) which is also a loff_t. Validate the value of offset and offset + length to make sure they do not overflow and appear as negative. Found by syzcaller with commit ff8c0c53c475 ("mm/hugetlb.c: don't call region_abort if region_chg fails") applied. Prior to this commit, the overflow would still occur but we would luckily return ENOMEM.
