2014-10-17tipc: fix bug in bundled buffer receptionJon Paul Maloy1-1/+6
In commit ec8a2e5621db2da24badb3969eda7fd359e1869f ("tipc: same receive code path for connection protocol and data messages") we omitted the the possiblilty that an arriving message extracted from a bundle buffer may be a multicast message. Such messages need to be to be delivered to the socket via a separate function, tipc_sk_mcast_rcv(). As a result, small multicast messages arriving as members of a bundle buffer will be silently dropped. This commit corrects the error by considering this case in the function tipc_link_bundle_rcv().

2014-10-17ipv6: introduce tcp_v6_iif()Eric Dumazet5-15/+30
Commit 971f10eca186 ("tcp: better TCP_SKB_CB layout to reduce cache line misses") added a regression for SO_BINDTODEVICE on IPv6. This is because we still use inet6_iif() which expects that IP6 control block is still at the beginning of skb->cb[] This patch adds tcp_v6_iif() helper and uses it where necessary. Because __inet6_lookup_skb() is used by TCP and DCCP, we add an iif parameter to it.

2014-10-17r8152: return -EBUSY for runtime suspendhayeswang1-7/+15
Remove calling cancel_delayed_work_sync() for runtime suspend, because it would cause dead lock. Instead, return -EBUSY to avoid the device enters suspending if the net is running and the delayed work is pending or running. The delayed work would try to wake up the device later, so the suspending is not necessary. Signed-off-by: Hayes Wang <[email protected]> Signed-off-by: David S. Miller <[email protected]>

2014-10-17openvswitch: Create right mask with disabled megaflowsPravin B Shelar1-21/+72
If megaflows are disabled, the userspace does not send the netlink attribute OVS_FLOW_ATTR_MASK, and the kernel must create an exact match mask. sw_flow_mask_set() sets every bytes (in 'range') of the mask to 0xff, even the bytes that represent padding for struct sw_flow, or the bytes that represent fields that may not be set during ovs_flow_extract(). This is a problem, because when we extract a flow from a packet, we do not memset() anymore the struct sw_flow to 0. This commit gets rid of sw_flow_mask_set() and introduces mask_set_nlattr(), which operates on the netlink attributes rather than on the mask key. Using this approach we are sure that only the bytes that the user provided in the flow are matched. Also, if the parse_flow_mask_nlattrs() for the mask ENCAP attribute fails, we now return with an error. This bug is introduced by commit 0714812134d7dcadeb7ecfbfeb18788aa7e1eaac ("openvswitch: Eliminate memset() from flow_extract").

2014-10-17Revert "Btrfs: race free update of commit root for ro snapshots"Chris Mason2-36/+33
This reverts commit 9c3b306e1c9e6be4be09e99a8fe2227d1005effc. Switching only one commit root during a transaction is wrong because it leads the fs into an inconsistent state. All commit roots should be switched at once, at transaction commit time, otherwise backref walking can often miss important references that were only accessible through the old commit root. Plus, the root item for the snapshot's root wasn't getting updated and preventing the next transaction commit to do it. This made several users get into random corruption issues after creation of readonly snapshots. A regression test for xfstests will follow soon.

2014-10-16Remap reserved posix characters by default (part 3/3)Steve French11-77/+88
This is a bigger patch, but its size is mostly due to a single change for how we check for remapping illegal characters in file names - a lot of repeated, small changes to the way callers request converting file names. The final patch in the series does the following: 1) changes default behavior for cifs to be more intuitive. Currently we do not map by default to seven reserved characters, ie those valid in POSIX but not in NTFS/CIFS/SMB3/Windows, unless a mount option (mapchars) is specified. Change this to by default always map and map using the SFM maping (like the Mac uses) unless the server negotiates the CIFS Unix Extensions (like Samba does when mounting with the cifs protocol) when the remapping of the characters is unnecessary. This should help SMB3 mounts in particular since Samba will likely be able to implement this mapping with its new "vfs_fruit" module as it will be doing for the Mac. 2) if the user specifies the existing "mapchars" mount option then use the "SFU" (Microsoft Services for Unix, SUA) style mapping of the seven characters instead. 3) if the user specifies "nomapposix" then disable SFM/MAC style mapping (so no character remapping would be used unless the user specifies "mapchars" on mount as well, as above). 4) change all the places in the code that check for the superblock flag on the mount which is set by mapchars and passed in on all path based operation and change it to use a small function call instead to set the mapping type properly (and check for the mapping type in the cifs unicode functions) Signed-off-by: Steve French <[email protected]>

2014-10-16Allow conversion of characters in Mac remap range. Part 1Steve French5-33/+107
This allows directory listings to Mac to display filenames correctly which have been created with illegal (to Windows) characters in their filename. It does not allow converting the other direction yet ie opening files with these characters (followon patch). There are seven reserved characters that need to be remapped when mounting to Windows, Mac (or any server without Unix Extensions) which are valid in POSIX but not in the other OS. : \ < > ? * | We used the normal UCS-2 remap range for this in order to convert this to/from UTF8 as did Windows Services for Unix (basically add 0xF000 to any of the 7 reserved characters), at least when the "mapchars" mount option was specified. Mac used a very slightly different "Services for Mac" remap range 0xF021 through 0xF027. The attached patch allows cifs.ko (the kernel client) to read directories on macs containing files with these characters and display their names properly. In theory this even might be useful on mounts to Samba when the vfs_catia or new "vfs_fruit" module is loaded. Currently the 7 reserved characters look very strange in directory listings from cifs.ko to Mac server. This patch allows these file name characters to be read (requires specifying mapchars on mount). Two additional changes are needed: 1) Make it more automatic: a way of detecting enough info so that we know to try to always remap these characters or not. Various have suggested that the SFM approach be made the default when the server does not support POSIX Unix extensions (cifs mounts to Samba for example) so need to make SFM remapping the default unless mapchars (SFU style mapping) specified on mount or no mapping explicitly requested or no mapping needed (cifs mounts to Samba). 2) Adding a patch to map the characters the other direction (ie UTF-8 to UCS-2 on open). This patch does it for translating readdir entries (ie UCS-2 to UTF-8) Signed-off-by: Steve French <[email protected]> Reviewed-by: Shirish Pargaonkar <[email protected]>

In addition the "sfu" mount option should not conflict with "mfsymlinks" (symlink emulation) as we will never create "sfu" style symlinks, but using "sfu" mount option will allow us to recognize existing symlinks, created with Microsoft "Services for Unix" (SFU and SUA). To enable the "sfu" mount option for SMB2/SMB3 the calling syntax of the generic cifs/smb2/smb3 sync_read and sync_write protocol dependent function needed to be changed (we don't have a file struct in all cases), but this actually ended up simplifying the code a little.

git://git.kernel.org/pub/scm/linux/kernel/git/jkirsher/net Jeff Kirsher says: ==================== Intel Wired LAN Driver Updates 2014-10-16 This series contains updates to fm10k and ixgbe. Matthew provides two fixes for fm10k, first sets the flag to fetch the host state before kicking off the service task that reads the host state when bringing the interface up. The second makes sure that we release the mailbox lock after detecting an error and before we return the error code. Andy Zhou provides a compile fix for fm10k, when the driver is compiled into the kernel and the VXLAN driver is compiled as a module. Emil provides a fix for ixgbe to prevent against a panic by trying to dereference a NULL pointer in ixgbe_ndo_set_vf_spoofchk(). ==================== Signed-off-by: David S.

2014-10-16ixgbe: check for vfs outside of sriov_num_vfs before dereferenceEmil Tantilov1-0/+3
The check for vfinfo is not sufficient because it does not protect against specifying vf that is outside of sriov_num_vfs range. All of the ndo functions have a check for it except for ixgbevf_ndo_set_spoofcheck(). The following patch is all we need to protect against this panic: ip link set p96p1 vf 0 spoofchk off BUG: unable to handle kernel NULL pointer dereference at 0000000000000052 IP: [<ffffffffa044a1c1>] ixgbe_ndo_set_vf_spoofchk+0x51/0x150 [ixgbe] Reported-by: Thierry Herbelot <[email protected]> Signed-off-by: Emil Tantilov <[email protected]> Acked-by: Thierry Herbelot <[email protected]> Signed-off-by: Jeff Kirsher <[email protected]>
