commit b22b1f17 upstream. Commit 79906964 uses the ext4_{set,clear}_inode_flags() functions to change the i_flags automatically but fails to remove the error setting of i_flags. So we still have the problem of trashing state flags. Fix this by removing the assignment. Signed-off-by:

commit 79906964 upstream. In commit 353eb83c we removed i_state_flags with 64-bit longs, But when handling the EXT4_IOC_SETFLAGS ioctl, we replace i_flags directly, which trashes the state flags which are stored in the high 32-bits of i_flags on 64-bit platforms. So use the the ext4_{set,clear}_inode_flags() functions which use atomic bit manipulation functions instead. Reported-by:

commit 9295b7a0 upstream. Programs using /proc/kpageflags need to know about the various flags. The <linux/kernel-page-flags.h> provides them and the comments in the file indicate that it is supposed to be used by user-level code. But the file is not installed. Install the headers and mark the unstable flags as out-of-bounds. The page-type tool is also adjusted to not duplicate the definitions Signed-off-by:

commit cbf8ae32 upstream. The memory the parameter __key points to is used as an iterator in btree_get_prev(), so if we save off a bkey() pointer in retry_key and then assign that to __key, we'll end up corrupting the btree internals when we do eg longcpy(__key, bkey(geo, node, i), geo->keylen); to return the key value. What we should do instead is use longcpy() to copy the key value that retry_key points to __key. This can cause a btree to get corrupted by seemingly read-only operations such as btree_for_each_safe.

commit c1bf94ec upstream. At some point pci_get_bus_and_slot started to enable interrupts. Since this function is used in the amd_iommu_resume path it will enable interrupts on resume which causes a warning. The fix will use a cached pointer to the root-bridge to re-enable the IOMMU in case the BIOS is broken. Signed-off-by:

commit a4dff304 upstream. Convert to use O_DSYNC for all cases at FILEIO backend creation time to avoid the extra syncing of pure timestamp updates with legacy O_SYNC during default operation as recommended by hch. Continue to do this independently of Write Cache Enable (WCE) bit, as WCE=0 is currently the default for all backend devices and enabled by user on per device basis via attrib/emulate_write_cache. This patch drops the now unnecessary fd_buffered_io= token usage that was originally signalling when to explictly disable O_SYNC at backend creation time for buffered I/O operation. This can end up being dangerous for a number of reasons during physical node failure, so go ahead and drop this option for now when O_DSYNC is used as the default. Also allow explict FUA WRITEs -> vfs_fsync_range() call to function in fd_execute_cmd() independently of WCE bit setting. Reported-by:

[ Upstream commit 91657eaf ] Corrects the function that determines the esp payload size. The calculations done in esp{4,6}_get_mtu() lead to overlength frames in transport mode for certain mtu values and suboptimal frames for others. According to what is done, mainly in esp{,6}_output() and tcp_mtu_to_mss(), net_header_len must be taken into account before doing the alignment calculation. Signed-off-by:

[ Upstream commit 617c8c11 ] At the beginning of __skb_cow, headroom gets set to a minimum of NET_SKB_PAD. This causes unnecessary reallocations if the buffer was not cloned and the headroom is just below NET_SKB_PAD, but still more than the amount requested by the caller. This was showing up frequently in my tests on VLAN tx, where vlan_insert_tag calls skb_cow_head(skb, VLAN_HLEN). Locally generated packets should have enough headroom, and for forward paths, we already have NET_SKB_PAD bytes of headroom, so we don't need to add any extra space here. Signed-off-by:

[ Upstream commit 477206a0 ] The r8169 may get stuck or show bad behaviour after activating TSO : the net_device is not stopped when it has no more TX descriptors. This problem comes from TX_BUFS_AVAIL which may reach -1 when all transmit descriptors are in use. The patch simply tries to keep positive values. Tested with 8111d(onboard) on a D510MO, and with 8111e(onboard) on a Zotac 890GXITX. Signed-off-by:

[ Upstream commit c51ce497 ] An application may call connect() to disconnect a socket using an address with family AF_UNSPEC. The L2TP IP sockets were not handling this case when the socket is not bound and an attempt to connect() using AF_UNSPEC in such cases would result in an oops. This patch addresses the problem by protecting the sk_prot->disconnect() call against trying to unhash the socket before it is bound. The patch also adds more checks that the sockaddr supplied to bind() and connect() calls is valid.

[ Upstream commit 0c183379 ] Since commit ad0081e4 "ipv6: Fragment locally generated tunnel-mode IPSec6 packets as needed" the fragment of packets is incorrect. because tunnel mode needs IPsec headers and trailer for all fragments, while on transport mode it is sufficient to add the headers to the first fragment and the trailer to the last. so modify mtu and maxfraglen base on ipsec mode and if fragment is first or last. with my test,it work well(every fragment's size is the mtu) and does not trigger slow fragment path. Changes from v1: though optimization, mtu_prev and maxfraglen_prev can be delete. replace xfrm mode codes with dst_entry's new frag DST_XFRM_TUNNEL. add fuction ip6_append_data_mtu to make codes clearer.

I was trying to backport the following commit to RHEL-6 From 0cea73465cd22373c5cd43a3edd25fbd4bb532ef Mon Sep 17 00:00:00 2001 From: Oliver Neukum <oliver@neukum.org> Date: Wed, 21 Sep 2011 11:37:15 +0200 Subject: [PATCH] btusb: add device entry for Broadcom SoftSailing and noticed it wasn't working on an HP Elitebook. Looking into the patch I noticed a very subtle typo in the ids. The patch has '0x05ac' instead of '0x0a5c'. A snippet of the lsusb -v output also shows this: Bus 002 Device 003: ID 0a5c:21e1 Broadcom Corp. Device Descriptor: bLength 18 bDescriptorType 1 bcdUSB 2.00 bDeviceClass 255 Vendor Specific Class bDeviceSubClass 1 bDeviceProtocol 1 bMaxPacketSize0 64 idVendor 0x0a5c Broadcom Corp. idProduct 0x21e1 bcdDevice 1.12 iManufacturer 1 Broadcom Corp iProduct 2 BCM20702A0 iSerial 3 60D819F0338C bNumConfigurations 1 Looking at other Broadcom ids, the fix matches them whereas the original patch matches Apple's ids. Tested on an HP Elitebook 8760w. The btusb binds and the userspace stuff loads correctly. Cc: Oliver Neukum <oliver@neukum.org> Signed-off-by:

commit 2e929d00 upstream. MTD_OF_PARTS and the default setting is not working due to using 'Y' instead of 'y', introduced in commit d6137bad. This made our board, and possibly other boards using DTS defined partitions and not having CONFIG_MTD_OF_PARTS=y defined in the defconfig, fail to mount root. Signed-off-by:

commit 95599968 upstream. We can't have references held on pages in the s_buddy_cache while we are trying to truncate its pages and put the inode. All the pages must be gone before we reach clear_inode. This can only be gauranteed if we can prevent new users from grabbing references to s_buddy_cache's pages. The original bug can be reproduced and the bug fix can be verified by: while true; do mount -t ext4 /dev/ram0 /export/hda3/ram0; \ umount /export/hda3/ram0; done & while true; do cat /proc/fs/ext4/ram0/mb_groups; done Signed-off-by:
