commit 0d3244d6 ("V4L/DVB (8342): sh_mobile_ceu_camera: Add SuperH Mobile CEU driver V3") introduced VIDEO_SH_MOBILE_CEU, which selects VIDEOBUF_DMA_CONTIG. This circumvents the dependency on HAS_DMA of VIDEOBUF_DMA_CONTIG. Add a dependency on HAS_DMA to VIDEO_SH_MOBILE_CEU to fix this.

This fixes a SWIOTLB oops With SWIOTLB being enabled and straight-forward page allocation failure [1], the swiotlb_alloc_coherent fall-back path hits an issue [2], resulting in my webcam failing to work. At the time of oops, RDI is clearly a pointer to a structure which has arrived as NULL, leading to the typo in swiotlb_map_single's callsite arguments. Correctly passing the device structure [3] addresses the issue and gets my webcam working again (the allocation failure still occuring). --- [1] skype: page allocation failure. order:3, mode:0x1 Pid: 5895, comm: skype Not tainted 2.6.27-rc6-235c-debug #1 Call Trace: [<ffffffff802b7cf0>] __alloc_pages_internal+0x4a0/0x5d0 [<ffffffff802d5ddd>] alloc_pages_current+0xad/0x110 [<ffffffff802b4ccd>] __get_free_pages+0x1d/0x60 [<ffffffff8046cd39>] swiotlb_alloc_coherent+0x49/0x180 [<ffffffff80212731>] dma_alloc_coherent+0x281/0x310 [<ffffffff805621c0>] hcd_buffer_alloc+0x50/0x90 [<ffffffff805547fd>] usb_buffer_alloc+0x2d/0x40 [<ffffffffa0056763>] uvc_alloc_urb_buffers+0x53/0xf0 [uvcvideo] [<ffffffffa0056958>] uvc_init_video+0x158/0x3e0 [uvcvideo] [<ffffffffa0056c17>] uvc_video_enable+0x37/0x80 [uvcvideo] [<ffffffffa0055853>] uvc_v4l2_do_ioctl+0x723/0x1260 [uvcvideo] [<ffffffff8026dd61>] ?

git commit 74811f35 causes crash at module load (or boot) time on my machine with a hpt374 controller. The reason for this is that for initializing second controller which sets (hwif->dev == host->dev[1]) to true (1), adds 1 to a void ptr, which advances it by one byte instead of advancing it by sizeof(hpt_info) bytes. Because of this, all initialization functions get corrupted data in info variable which causes a crash at boot time. This patch fixes that and makes my machine boot again. The card itself is a HPT374 raid conroller: Here is the lspci -v output: 03:06.0 RAID bus controller: HighPoint Technologies, Inc. HPT374 (rev 07) Subsystem: HighPoint Technologies, Inc.

ocfs2 will become read-only if we try to read the bytes which pass the end of i_size. This can be easily reproduced by following steps: 1. mkfs a ocfs2 volume with bs=4k cs=4k and nosparse. 2. create a small file(say less than 100 bytes) and we will create the file which is allocated 1 cluster. 3. read 8196 bytes from the kernel using O_DIRECT which exceeds the limit. 4. The ocfs2 volume becomes read-only and dmesg shows: OCFS2: ERROR (device sda13): ocfs2_direct_IO_get_blocks: Inode 66010 has a hole at block 1 File system is now read-only due to the potential of on-disk corruption. Please run fsck.ocfs2 once the file system is unmounted. So suppress the ERROR message. Signed-off-by: NTao Ma <tao.ma@oracle.com> Signed-off-by: NMark Fasheh <mfasheh@suse.com>

This fixes kernel bugzilla 11469: "TUN with 1024 neighbours: ip6_dst_lookup_tail NULL crash" dst->neighbour is not necessarily hooked up at this point in the processing path, so blindly dereferencing it is the wrong thing to do. This NULL check exists in other similar paths and this case was just an oversight. Also fix the completely wrong and confusing indentation here while we're at it.

-
由 Thomas Gleixner 提交于
The issue of the endless reprogramming loop due to a too small min_delta_ns was fixed with the previous updates of the clock events code, but we had no information about the spread of this problem. I added a WARN_ON to get automated information via kerneloops.org and to get some direct reports, which allowed me to analyse the affected machines. The WARN_ON has served its purpose and would be annoying for a release kernel. Remove it and just keep the information about the increase of the min_delta_ns value.

The strcmp() always returns !0 and never resets the value for e820.nr_map and returns an incorrect user-defined map. This patch fixes the problem.

It was introduced by "vsprintf: add support for '%pS' and '%pF' pointer formats" in commit 0fe1ef24. However, the current way its coded doesn't work on parisc64. For two reasons: 1) parisc isn't in the #ifdef and 2) parisc has a different format for function descriptors Make dereference_function_descriptor() more accommodating by allowing architecture overrides. I put the three overrides (for parisc64, ppc64 and ia64) in arch/kernel/module.c because that's where the kernel internal linker which knows how to deal with function descriptors sits.

When disconnected ccw devices are removed, the device has to be set offline, otherwise there will be side effects including a reference count imbalance.

When running a 31-bit ptrace, on either an s390 or s390x kernel, reads and writes into a padding area in struct user_regs_struct32 will result in a kernel panic. This is also known as CVE-2008-1514. Test case available here: http://sources.redhat.com/cgi-bin/cvsweb.cgi/~checkout~/tests/ptrace-tests/tests/user-area-padding.c?cvsroot=systemtap Steps to reproduce: 1) wget the above 2) gcc -o user-area-padding-31bit user-area-padding.c -Wall -ggdb2 -D_GNU_SOURCE -m31 3) ./user-area-padding-31bit <panic> Test status ----------- Without patch, both s390 and s390x kernels panic. With patch, the test case, as well as the gdb testsuite, pass without incident, padding area reads returning zero, writes ignored. Nb: original version returned -EINVAL on write attempts, which broke the gdb test and made the test case slightly unhappy, Jan Kratochvil suggested the change to return 0 on write attempts.

The Security Mode 4 of the Bluetooth 2.1 specification has strict authentication and encryption requirements. It is the initiators job to create a secure ACL link. However in case of malicious devices, the acceptor has to make sure that the ACL is encrypted before allowing any kind of L2CAP connection. The only exception here is the PSM 1 for the service discovery protocol, because that is allowed to run on an insecure ACL link. Previously it was enough to reject a L2CAP connection during the connection setup phase, but with Bluetooth 2.1 it is forbidden to do any L2CAP protocol exchange on an insecure link (except SDP). The new hci_conn_check_link_mode() function can be used to check the integrity of an ACL link. This functions also takes care of the cases where Security Mode 4 is disabled or one of the devices is based on an older specification. Signed-off-by: NMarcel Holtmann <marcel@holtmann.org>

With the introduction of Security Mode 4 and Simple Pairing from the Bluetooth 2.1 specification it became mandatory that the initiator requires authentication and encryption before any L2CAP channel can be established. The only exception here is PSM 1 for the service discovery protocol (SDP). It is meant to be used without any encryption since it contains only public information. This is how Bluetooth 2.0 and before handle connections on PSM 1. For Bluetooth 2.1 devices the pairing procedure differentiates between no bonding, general bonding and dedicated bonding. The L2CAP layer wrongly uses always general bonding when creating new connections, but it should not do this for SDP connections. In this case the authentication requirement should be no bonding and the just-works model should be used, but in case of non-SDP connection it is required to use general bonding. If the new connection requires man-in-the-middle (MITM) protection, it also first wrongly creates an unauthenticated link key and then later on requests an upgrade to an authenticated link key to provide full MITM protection. With Simple Pairing the link key generation is an expensive operation (compared to Bluetooth 2.0 and before) and doing this twice during a connection setup causes a noticeable delay when establishing a new connection. This should be avoided to not regress from the expected Bluetooth 2.0 connection times. The authentication requirements are known up-front and so enforce them. To fulfill these requirements the hci_connect() function has been extended with an authentication requirement parameter that will be stored inside the connection information and can be retrieved by userspace at any time. This allows the correct IO capabilities exchange and results in the expected behavior. Signed-off-by: NMarcel Holtmann <marcel@holtmann.org>

The ACL config stage keeps holding a reference count on incoming connections when requesting the extended features. This results in keeping an ACL link up without any users. The problem here is that the Bluetooth specification doesn't define an ownership of the ACL link and thus it can happen that the implementation on the initiator side doesn't care about disconnecting unused links. In this case the acceptor needs to take care of this. Signed-off-by: NMarcel Holtmann <marcel@holtmann.org>
