2013-07-23staging: gdm72xx: potential use after free in send_qos_list()Dan Carpenter
Sometimes free_qos_entry() sometimes frees its argument. I have moved the dereference of "entry" ahead on line to avoid a use after free. Signed-off-by: Dan Carpenter <dan.carpenter@oracle.com> Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>

Commit ac4c1a9b33 ("staging: drm/imx: Add LDB support") added the DRM_IMX_LDB Kconfig entry. That entry selects OF_VIDEOMODE. But there is no Kconfig symbol named OF_VIDEOMODE.

2013-07-23staging: comedi: fix a race between do_cmd_ioctl() and read/writeIan Abbott
`do_cmd_ioctl()` is called with the comedi device's mutex locked to process the `COMEDI_CMD` ioctl to set up comedi's asynchronous command handling on a comedi subdevice. `comedi_read()` and `comedi_write()` are the `read` and `write` handlers for the comedi device, but do not lock the mutex (for performance reasons, as some things can hold the mutex for quite a long time). There is a race condition if `comedi_read()` or `comedi_write()` is running at the same time and for the same file object and comedi subdevice as `do_cmd_ioctl()`. `do_cmd_ioctl()` sets the subdevice's `busy` pointer to the file object way before it sets the `SRF_RUNNING` flag in the subdevice's `runflags` member. `comedi_read() and `comedi_write()` check the subdevice's `busy` pointer is pointing to the current file object, then if the `SRF_RUNNING` flag is not set, will call `do_become_nonbusy()` to shut down the asyncronous command. Bad things can happen if the asynchronous command is being shutdown and set up at the same time. To prevent the race, don't set the `busy` pointer until after the `SRF_RUNNING` flag has been set. Also, make sure the mutex is held in `comedi_read()` and `comedi_write()` while calling `do_become_nonbusy()` in order to avoid moving the race condition to a point within that function. Change some error handling `goto cleanup` statements in `do_cmd_ioctl()` to simple `return -ERRFOO` statements as a result of changing when the `busy` pointer is set.

2013-07-23staging: comedi: COMEDI_CANCEL ioctl should wake up read/writeIan Abbott
Comedi devices can do blocking read() or write() (or poll()) if an asynchronous command has been set up, blocking for data (for read()) or buffer space (for write()). Various events associated with the asynchronous command will wake up the blocked reader or writer (or poller). It is also possible to force the asynchronous command to terminate by issuing a `COMEDI_CANCEL` ioctl. That shuts down the asynchronous command, but does not currently wake up the blocked reader or writer (or poller). If the blocked task could be woken up, it would see that the command is no longer active and return. The caller of the `COMEDI_CANCEL` ioctl could attempt to wake up the blocked task by sending a signal, but that's a nasty workaround. Change `do_cancel_ioctl()` to wake up the wait queue after it returns from `do_cancel()`. `do_cancel()` can propagate an error return value from the low-level comedi driver's cancel routine, but it always shuts the command down regardless, so `do_cancel_ioctl()` can wake up he wait queue regardless of the return value from `do_cancel()`.

Thus we do not reach nfs4_file_get_access() and fi_access[O_WRONLY] is not incremented. 2) Second time around, in nfs4_get_vfs_file() fp->fi_fds[O_WRONLY] is NOT NULL (-ETXTBSY), so nfsd_open() is NOT called, but nfs4_file_get_access() IS called and fi_access[O_WRONLY] is incremented. Thus we leave a landmine in the form of the nfs4_file data structure in an incorrect state. 3) Eventually, when __nfs4_file_put_access() is called it finds fi_access[O_WRONLY] being non-zero, it decrements it and calls nfs4_file_put_fd() which tries to fput -ETXTBSY. ------------------------------------------------------------ ...

2013-07-23[SCSI] sd: fix crash when UA received on DIF enabled deviceEwan D. Milne
sd_prep_fn will allocate a larger CDB for the command via mempool_alloc for devices using DIF type 2 protection. This CDB was being freed in sd_done, which results in a kernel crash if the command is retried due to a UNIT ATTENTION. This change moves the code to free the larger CDB into sd_unprep_fn instead, which is invoked after the request is complete. It is no longer necessary to call scsi_print_command separately for this case as the ->cmnd will no longer be NULL in the normal code path. Also removed conditional test for DIF type 2 when freeing the larger CDB because the protection_type could have been changed via sysfs while the command was executing. Signed-off-by: Ewan D.

The race is caused when an I/O termination in the SCU hardware is necessary because of an SSP target timeout condition, and the check of the I/O end state races against the HW-termination-driven end state. The failure of the race meant that no TMF was sent to the device to clean-up the pending I/O.

2013-07-23drm/i915: fix hdmi portclock limitsDaniel Vetter
In commit 325b9d048810f7689ec644595061c0b700e64bce Author: Daniel Vetter <daniel.vetter@ffwll.ch> Date: Fri Apr 19 11:24:33 2013 +0200 drm/i915: fixup 12bpc hdmi dotclock handling I've errornously claimed that we don't yet support the hdmi 1.4 dotclocks > 225 MHz on Haswell. But a bug report and a closer look at the wrpll table showed that we've supported port clocks up to 300MHz. With the new code to dynamically compute wrpll limits we should have no issues going up to the full 340 MHz range of hdmi 1.4, so let's just use that to fix this regression. That'll allow 4k over hdmi for free! v2: Drop the random hunk that somehow slipped in. v3: Cantiga has the original HDMI dotclock limit of 165MHz. And also patch up the mode filtering. To do so extract the dotclock limits into a little helper function. v4: Use 300MHz (from Bspec) instead of 340MHz (upper limit for hdmi 1.3), apparently hw is not required to be able to drive the highest dotclocks.

Commit 8ef6e6201b26cb9fde79c1baa08145af6aca2815 (ARM: footbridge: use fixed PCI i/o mapping) broke booting on my netwinder. Before that, everything boots fine. Since then, it crashes on boot.

Russell points out it's because of overlapping PCI mappings that was added with the aforementioned commit. Rob thought the code would re-use the static mapping, but that turns out to not be the case and instead hits the BUG further down.

2013-07-23virtio/console: Add pipe_lock/unlock for splice_writeYoshihiro YUNOMAE
Add pipe_lock/unlock for splice_write to avoid oops by following competition: (1) An application gets fds of a trace buffer, virtio-serial, pipe. (2) The application does fork() (3) The processes execute splice_read(trace buffer) and splice_write(virtio-serial) via same pipe. <parent> <child> get fds of a trace buffer, virtio-serial, pipe | fork()----------create--------+ | | splice(read) | ---+ splice(write) | +-- no competition | splice(read) | | splice(write) ---+ | | splice(read) | splice(write) splice(read) ------ competition | splice(write) Two processes share a pipe_inode_info structure. If the child execute splice(read) when the parent tries to execute splice(write), the structure can be broken. Existing virtio-serial driver does not get lock for the structure in splice_write, so this competition will induce oops. <oops messages> BUG: unable to handle kernel NULL pointer dereference at 0000000000000018 IP: [<ffffffff811a6b5f>] splice_from_pipe_feed+0x6f/0x130 PGD 7223e067 PUD 72391067 PMD 0 Oops: 0000 [#1] SMP Modules linked in: lockd bnep bluetooth rfkill sunrpc ip6t_REJECT nf_conntrack_ipv6 nf_defrag_ipv6 xt_state nf_conntrack ip6table_filter ip6_tables snd_hda_intel snd_hda_codec snd_hwdep snd_pcm snd_page_alloc snd_timer snd soundcore pcspkr virtio_net virtio_balloon i2c_piix4 i2c_core microcode uinput floppy CPU: 0 PID: 1072 Comm: compete-test Not tainted 3.10.0ws+ #55 Hardware name: Bochs Bochs, BIOS Bochs 01/01/2007 task: ffff880071b98000 ti: ffff88007b55e000 task.ti: ffff88007b55e000 RIP: 0010:[<ffffffff811a6b5f>] [<ffffffff811a6b5f>] splice_from_pipe_feed+0x6f/0x130 RSP: 0018:ffff88007b55fd78 EFLAGS: 00010287 RAX: 0000000000000000 RBX: ffff88007b55fe20 RCX: 0000000000000000 RDX: 0000000000001000 RSI: ffff88007a95ba30 RDI: ffff880036f9e6c0 RBP: ffff88007b55fda8 R08: 00000000000006ec R09: ffff880077626708 R10: 0000000000000003 R11: ffffffff8139ca59 R12: ffff88007a95ba30 R13: 0000000000000000 R14: ffffffff8139dd00 R15: ffff880036f9e6c0 FS: 00007f2e2e3a0740(0000) GS:ffff88007fc00000(0000) knlGS:0000000000000000 CS: 0010 DS: 0000 ES: 0000 CR0: 000000008005003b CR2: 0000000000000018 CR3: 0000000071bd1000 CR4: 00000000000006f0 DR0: 0000000000000000 DR1: 0000000000000000 DR2: 0000000000000000 DR3: 0000000000000000 DR6: 00000000ffff0ff0 DR7: 0000000000000400 Stack: ffffffff8139ca59 ffff88007b55fe20 ffff880036f9e6c0 ffffffff8139dd00 ffff8800776266c0 ffff880077626708 ffff88007b55fde8 ffffffff811a6e8e ffff88007b55fde8 ffffffff8139ca59 ffff880036f9e6c0 ffff88007b55fe20 Call Trace: [<ffffffff8139ca59>] ? alloc_buf.isra.13+0x39/0xb0 [<ffffffff8139dd00>] ? virtcons_restore+0x100/0x100 [<ffffffff811a6e8e>] __splice_from_pipe+0x7e/0x90 [<ffffffff8139ca59>] ? alloc_buf.isra.13+0x39/0xb0 [<ffffffff8139d739>] port_fops_splice_write+0xe9/0x140 [<ffffffff8127a3f4>] ? selinux_file_permission+0xc4/0x120 [<ffffffff8139d650>] ? wait_port_writable+0x1b0/0x1b0 [<ffffffff811a6fe0>] do_splice_from+0xa0/0x110 [<ffffffff811a951f>] SyS_splice+0x5ff/0x6b0 [<ffffffff8161facf>] tracesys+0xdd/0xe2 Code: 49 8b 87 80 00 00 00 4c 8d 24 d0 8b 53 04 41 8b 44 24 0c 4d 8b 6c 24 10 39 d0 89 03 76 02 89 13 49 8b 44 24 10 4c 89 e6 4c 89 ff <ff> 50 18 85 c0 0f 85 aa 00 00 00 48 89 da 4c 89 e6 4c 89 ff 41 RIP [<ffffffff811a6b5f>] splice_from_pipe_feed+0x6f/0x130 RSP <ffff88007b55fd78> CR2: 0000000000000018 ---[ end trace 24572beb7764de59 ]--- V2: Fix a locking problem for error V3: Add Reviewed-by lines and stable@ line in sign-off area Signed-off-by: Yoshihiro YUNOMAE <yoshihiro.yunomae.ez@hitachi.com> Reviewed-by: Amit Shah <amit.shah@redhat.com> Reviewed-by: Masami Hiramatsu <masami.hiramatsu.pt@hitachi.com> Cc: Amit Shah <amit.shah@redhat.com> Cc: Arnd Bergmann <arnd@arndb.de> Cc: Greg Kroah-Hartman <gregkh@linuxfoundation.org> Cc: stable@vger.kernel.org Signed-off-by: Rusty Russell <rusty@rustcorp.com.au>

Thus if we want to exit because of the krealloc() failure, we must make sure the original one is freed. - The error code path of the x86 package temperature thermal driver's initialization routine makes an unbalanced call to get_online_cpus(), which causes subsequent CPU offline operations, and consequently system suspend, to permanently block in cpu_hotplug_begin() on systems where get_core_online() returns an error code.

2013-07-22sfc: Enable RX scatter for flows steered by RFSBen Hutchings
Received packets are only scattered if this is enabled in both the matching filter and the receiving queue. This was not being done for filters inserted for RFS, so any packet requiring more than a single descriptor was dropped.

2013-07-22net: pch_gbe depends on x86Jiri Slaby
Since 4bb1667255a86360721291fe59991d033bbc2f2a (build some drivers only when compile-testing), PTP_1588_CLOCK_PCH depends on (X86 || COMPILE_TEST). But PCH_GBE selects PTP_1588_CLOCK_PCH without depending on x86. Fix this by adding the same dependency here.

Pablo Neira Ayuso says: ==================== The following patchset contains Netfilter fixes for your net tree, they are: * Fix potential NULL dereference in the socket match if revision 0 is used, from Eric Dumazet. * Fix missing expectation NAT initialization that results in dumping the NAT part via ctnetlink, thus leading to problems in expectation synchronization through conntrackd, from myself. ==================== Signed-off-by: David S.
