commit 9e4982f6 upstream. Like with ath9k, ath5k queues also need to be ordered by priority. queue_info->tqi_subtype already contains the correct index, so use it instead of relying on the order of ath5k_hw_setup_tx_queue calls. Signed-off-by:

commit ad8fdccf upstream. The driver passes the desired hardware queue index for a WMM data queue in qinfo->tqi_subtype. This was ignored in ath9k_hw_setuptxqueue, which instead relied on the order in which the function is called. Reported-by:

commit c1c6156f upstream. This function isn't right and it causes a static checker warning: drivers/md/dm-thin.c:3016 maybe_resize_data_dev() error: potentially using uninitialized 'sb_data_size'. It should set "*count" and return zero on success the same as the sm_metadata_get_nr_blocks() function does earlier. Fixes: 3241b1d3 ('dm: add persistent data library') Signed-off-by:

commit 69eba10e upstream. In olden times the snd_hda_param_read() function always set "*start_id" but in 2007 we introduced a new return and it causes uninitialized data bugs in a couple of the callers: print_codec_info() and hdmi_parse_codec(). Fixes: e8a7f136 ('[ALSA] hda-intel - Improve HD-audio codec probing robustness') Signed-off-by:

commit 94208064 upstream. Dmitry Chernenkov used KASAN to discover that eCryptfs writes past the end of the allocated buffer during encrypted filename decoding. This fix corrects the issue by getting rid of the unnecessary 0 write when the current bit offset is 2. Signed-off-by:

commit 1a5fb99d upstream. Some boards with TC6393XB chip require full state restore during system resume thanks to chip's VCC being cut off during suspend (Sharp SL-6000 tosa is one of them). Failing to do so would result in ohci Oops on resume due to internal memory contentes being changed. Fail ohci suspend on tc6393xb is full state restore is required. Recommended workaround is to unbind tmio-ohci driver before suspend and rebind it after resume. Signed-off-by:

commit 36e81648 upstream. Commit 6ac665c6 ("PCI: rewrite PCI BAR reading code") masked off low-order bits from 'l', but not from 'sz'. Both are passed to pci_size(), which compares 'base == maxbase' to check for read-only BARs. The masking of 'l' means that comparison will never be 'true', so the check for read-only BARs no longer works. Resolve this by also masking off the low-order bits of 'sz' before passing it into pci_size() as 'maxbase'. With this change, pci_size() will once again catch the problems that have been encountered to date: - AGP aperture BAR of AMD-7xx host bridges: if the AGP window is disabled, this BAR is read-only and read as 0x00000008 [1] - BARs 0-4 of ALi IDE controllers can be non-zero and read-only [1] - Intel Sandy Bridge - Thermal Management Controller [8086:0103]; BAR 0 returning 0xfed98004 [2] - Intel Xeon E5 v3/Core i7 Power Control Unit [8086:2fc0]; Bar 0 returning 0x00001a [3] Link: [1] https://git.kernel.org/cgit/linux/kernel/git/tglx/history.git/commit/drivers/pci/probe.c?id=1307ef6621991f1c4bc3cec1b5a4ebd6fd3d66b9 ("PCI: probing read-only BARs" (pre-git)) Link: [2] https://bugzilla.kernel.org/show_bug.cgi?id=43331 Link: [3] https://bugzilla.kernel.org/show_bug.cgi?id=85991Reported-by:

commit 0372ffb3 upstream. bus_find_device_by_name() acquires a device reference which is never released. This results in an object leak, which on older kernels results in failure to release all resources of PCI devices. libvirt uses drivers_probe to re-attach devices to the host after assignment and is therefore a common trigger for this leak. Example: # cd /sys/bus/pci/ # dmesg -C # echo 1 > devices/0000\:01\:00.0/sriov_numvfs # echo 0 > devices/0000\:01\:00.0/sriov_numvfs # dmesg | grep 01:10 pci 0000:01:10.0: [8086:10ca] type 00 class 0x020000 kobject: '0000:01:10.0' (ffff8801d79cd0a8): kobject_add_internal: parent: '0000:00:01.0', set: 'devices' kobject: '0000:01:10.0' (ffff8801d79cd0a8): kobject_uevent_env kobject: '0000:01:10.0' (ffff8801d79cd0a8): fill_kobj_path: path = '/devices/pci0000:00/0000:00:01.0/0000:01:10.0' kobject: '0000:01:10.0' (ffff8801d79cd0a8): kobject_uevent_env kobject: '0000:01:10.0' (ffff8801d79cd0a8): fill_kobj_path: path = '/devices/pci0000:00/0000:00:01.0/0000:01:10.0' kobject: '0000:01:10.0' (ffff8801d79cd0a8): kobject_uevent_env kobject: '0000:01:10.0' (ffff8801d79cd0a8): fill_kobj_path: path = '/devices/pci0000:00/0000:00:01.0/0000:01:10.0' kobject: '0000:01:10.0' (ffff8801d79cd0a8): kobject_cleanup, parent (null) kobject: '0000:01:10.0' (ffff8801d79cd0a8): calling ktype release kobject: '0000:01:10.0': free name [kobject freed as expected] # dmesg -C # echo 1 > devices/0000\:01\:00.0/sriov_numvfs # echo 0000:01:10.0 > drivers_probe # echo 0 > devices/0000\:01\:00.0/sriov_numvfs # dmesg | grep 01:10 pci 0000:01:10.0: [8086:10ca] type 00 class 0x020000 kobject: '0000:01:10.0' (ffff8801d79ce0a8): kobject_add_internal: parent: '0000:00:01.0', set: 'devices' kobject: '0000:01:10.0' (ffff8801d79ce0a8): kobject_uevent_env kobject: '0000:01:10.0' (ffff8801d79ce0a8): fill_kobj_path: path = '/devices/pci0000:00/0000:00:01.0/0000:01:10.0' kobject: '0000:01:10.0' (ffff8801d79ce0a8): kobject_uevent_env kobject: '0000:01:10.0' (ffff8801d79ce0a8): fill_kobj_path: path = '/devices/pci0000:00/0000:00:01.0/0000:01:10.0' kobject: '0000:01:10.0' (ffff8801d79ce0a8): kobject_uevent_env kobject: '0000:01:10.0' (ffff8801d79ce0a8): fill_kobj_path: path = '/devices/pci0000:00/0000:00:01.0/0000:01:10.0' [no free] Signed-off-by:

commit f38aed97 upstream. The logic of vfree()'ing vol->upd_buf is tied to vol->updating. In ubi_start_update() vol->updating is set long before vmalloc()'ing vol->upd_buf. If we encounter a write failure in ubi_start_update() before vmalloc() the UBI device release function will try to vfree() vol->upd_buf because vol->updating is set. Fix this by allocating vol->upd_buf directly after setting vol->updating.

Instead of trying to be clever and only flush on specific CRs, let play safe and flush on all lctl(g) as future machines might define new bits in CRs.

It has been reported that generating an MLD listener report on devices with large MTUs (e.g. 9000) and a high number of IPv6 addresses can trigger a skb_over_panic(): skbuff: skb_over_panic: text:ffffffff80612a5d len:3776 put:20 head:ffff88046d751000 data:ffff88046d751010 tail:0xed0 end:0xec0 dev:port1 ------------[ cut here ]------------ kernel BUG at net/core/skbuff.c:100! invalid opcode: 0000 [#1] SMP Modules linked in: ixgbe(O) CPU: 3 PID: 0 Comm: swapper/3 Tainted: G O 3.14.23+ #4 [...] Call Trace: <IRQ> [<ffffffff80578226>] ? skb_put+0x3a/0x3b [<ffffffff80612a5d>] ? add_grhead+0x45/0x8e [<ffffffff80612e3a>] ? add_grec+0x394/0x3d4 [<ffffffff80613222>] ? mld_ifc_timer_expire+0x195/0x20d [<ffffffff8061308d>] ? mld_dad_timer_expire+0x45/0x45 [<ffffffff80255b5d>] ? call_timer_fn.isra.29+0x12/0x68 [<ffffffff80255d16>] ? run_timer_softirq+0x163/0x182 [<ffffffff80250e6f>] ? __do_softirq+0xe0/0x21d [<ffffffff8025112b>] ? irq_exit+0x4e/0xd3 [<ffffffff802214bb>] ? smp_apic_timer_interrupt+0x3b/0x46 [<ffffffff8063f10a>] ? apic_timer_interrupt+0x6a/0x70 mld_newpack() skb allocations are usually requested with dev->mtu in size, since commit 72e09ad1 ("ipv6: avoid high order allocations") we have changed the limit in order to be less likely to fail. However, in MLD/IGMP code, we have some rather ugly AVAILABLE(skb) macros, which determine if we may end up doing an skb_put() for adding another record. To avoid possible fragmentation, we check the skb's tailroom as skb->dev->mtu - skb->len, which is a wrong assumption as the actual max allocation size can be much smaller. The IGMP case doesn't have this issue as commit 57e1ab6e ("igmp: refine skb allocations") stores the allocation size in the cb[]. Set a reserved_tailroom to make it fit into the MTU and use skb_availroom() helper instead. This also allows to get rid of igmp_skb_size(). Reported-by:

commit a7ae1992 upstream. ipv6: Remove all uses of LL_ALLOCATED_SPACE The macro LL_ALLOCATED_SPACE was ill-conceived. It applies the alignment to the sum of needed_headroom and needed_tailroom. As the amount that is then reserved for head room is needed_headroom with alignment, this means that the tail room left may be too small. This patch replaces all uses of LL_ALLOCATED_SPACE in net/ipv6 with the macro LL_RESERVED_SPACE and direct reference to needed_tailroom. This also fixes the problem with needed_headroom changing between allocating the skb and reserving the head room. Signed-off-by:

commit 11432050 upstream. This patch fixes an issue that the NULL pointer dereference happens when we uses g_audio driver. Since the g_audio driver will call usb_ep_disable() in afunc_set_alt() before it calls usb_ep_enable(), the uep->pipe of renesas usbhs driver will be NULL. So, this patch adds a condition to avoid the oops. Signed-off-by:
