ClientGUID must be zero for SMB2.02 dialect. See section 2.2.3 of MS-SMB2. For SMB2.1 and later it must be non-zero. Signed-off-by: NSteve French <smfrench@gmail.com> CC: Sachin Prabhu <sprabhu@redhat.com>

When mounting from a Windows 2012R2 server, we hit the following problem: 1) Mount with any of the following versions - 2.0, 2.1 or 3.0 2) unmount 3) Attempt a mount again using a different SMB version >= 2.0. You end up with the following failure: Status code returned 0xc0000203 STATUS_USER_SESSION_DELETED CIFS VFS: Send error in SessSetup = -5 CIFS VFS: cifs_mount failed w/return code = -5 I cannot reproduce this issue using a Windows 2008 R2 server. This appears to be caused because we use the same client guid for the connection on first mount which we then disconnect and attempt to mount again using a different protocol version. By generating a new guid each time a new connection is Negotiated, we avoid hitting this problem. Signed-off-by: NSachin Prabhu <sprabhu@redhat.com> Signed-off-by: NSteve French <smfrench@gmail.com>

The handling of the CIFS_INO_INVALID_MAPPING flag is racy. It's possible for two tasks to attempt to revalidate the mapping at the same time. The first sees that CIFS_INO_INVALID_MAPPING is set. It clears the flag and then calls invalidate_inode_pages2 to start shooting down the pagecache. While that's going on, another task checks the flag and sees that it's clear. It then ends up trusting the pagecache to satisfy a read when it shouldn't. Fix this by adding a bitlock to ensure that the clearing of the flag is atomic with respect to the actual cache invalidation. Also, move the other existing users of cifs_invalidate_mapping to use a new cifs_zap_mapping() function that just sets the INVALID_MAPPING bit and then uses the standard codepath to handle the invalidation.

In later patches, we'll need to have a bitlock, so go ahead and convert these bools to use atomic bitops instead. Also, clean up the initialization of the flags field. There's no need to unset each bit individually just after it was zeroed on allocation. Signed-off-by: NJeff Layton <jlayton@poochiereds.net> Signed-off-by: NSteve French <smfrench@gmail.com>

Currently, when the top and bottom 32-bit words are equivalent and the host is a 32-bit arch, cifs_uniqueid_to_ino_t returns 0 as the ino_t value. All we're doing to hash the value down to 32 bits is xor'ing the top and bottom 32-bit words and that obviously results in 0 if they are equivalent. The kernel doesn't really care if it returns this value, but some userland apps (like "ls") will ignore dirents that have a zero d_ino value. Change this function to use hash_64 to convert this value to a 31 bit value and then add 1 to ensure that it doesn't ever return 0. Also, there's no need to check the sizeof(ino_t) at runtime so create two different cifs_uniqueid_to_ino_t functions based on whether BITS_PER_LONG is 64 for not.

When running send, if an inode only has extended reference items associated to it and no regular references, send.c:get_first_ref() was incorrectly assuming the reference it found was of type BTRFS_INODE_REF_KEY due to use of the wrong key variable. This caused weird behaviour when using the found item has a regular reference, such as weird path string, and occasionally (when lucky) a crash: [ 190.600652] general protection fault: 0000 [#1] SMP DEBUG_PAGEALLOC [ 190.600994] Modules linked in: btrfs xor raid6_pq binfmt_misc nfsd auth_rpcgss oid_registry nfs_acl nfs lockd fscache sunrpc psmouse serio_raw evbug pcspkr i2c_piix4 e1000 floppy [ 190.602565] CPU: 2 PID: 14520 Comm: btrfs Not tainted 3.13.0-fdm-btrfs-next-26+ #1 [ 190.602728] Hardware name: Bochs Bochs, BIOS Bochs 01/01/2011 [ 190.602868] task: ffff8800d447c920 ti: ffff8801fa79e000 task.ti: ffff8801fa79e000 [ 190.603030] RIP: 0010:[<ffffffff813266b4>] [<ffffffff813266b4>] memcpy+0x54/0x110 [ 190.603262] RSP: 0018:ffff8801fa79f880 EFLAGS: 00010202 [ 190.603395] RAX: ffff8800d4326e3f RBX: 000000000000036a RCX: ffff880000000000 [ 190.603553] RDX: 000000000000032a RSI: ffe708844042936a RDI: ffff8800d43271a9 [ 190.603710] RBP: ffff8801fa79f8c8 R08: 00000000003a4ef0 R09: 0000000000000000 [ 190.603867] R10: 793a4ef09f000000 R11: 9f0000000053726f R12: ffff8800d43271a9 [ 190.604020] R13: 0000160000000000 R14: ffff8802110134f0 R15: 000000000000036a [ 190.604020] FS: 00007fb423d09b80(0000) GS:ffff880216200000(0000) knlGS:0000000000000000 [ 190.604020] CS: 0010 DS: 0000 ES: 0000 CR0: 000000008005003b [ 190.604020] CR2: 00007fb4229d4b78 CR3: 00000001f5d76000 CR4: 00000000000006e0 [ 190.604020] Stack: [ 190.604020] ffffffffa01f4d49 ffff8801fa79f8f0 00000000000009f9 ffff8801fa79f8c8 [ 190.604020] 00000000000009f9 ffff880211013260 000000000000f971 ffff88021147dba8 [ 190.604020] 00000000000009f9 ffff8801fa79f918 ffffffffa02367f5 ffff8801fa79f928 [ 190.604020] Call Trace: [ 190.604020] [<ffffffffa01f4d49>] ? read_extent_buffer+0xb9/0x120 [btrfs] [ 190.604020] [<ffffffffa02367f5>] fs_path_add_from_extent_buffer+0x45/0x60 [btrfs] [ 190.604020] [<ffffffffa0238806>] get_first_ref+0x1f6/0x210 [btrfs] [ 190.604020] [<ffffffffa0238994>] __get_cur_name_and_parent+0x174/0x3a0 [btrfs] [ 190.604020] [<ffffffff8118df3d>] ? kmem_cache_alloc_trace+0x11d/0x1e0 [ 190.604020] [<ffffffffa0236674>] ? fs_path_alloc+0x24/0x60 [btrfs] [ 190.604020] [<ffffffffa0238c91>] get_cur_path+0xd1/0x240 [btrfs] (...)

For inline data extent, we need to make its length aligned, otherwise, we can get a phantom extent map which confuses readpages() to return -EIO. This can be detected by xfstests/btrfs/035.

The new renameat2 syscall provides all the functionality of renameat with an additional flags argument, so make renameat optional so that future architectures can omit it without getting a warning. This patch doesn't affect existing architectures.
