commit 45292be0 upstream. For some reason, the driver does not consider allocation of the subdevice private data to be a fatal error when attaching the COMEDI device. It tests the subdevice private data pointer for validity at certain points, but omits some crucial tests. In particular, `jr3_pci_auto_attach()` calls `jr3_pci_alloc_spriv()` to allocate and initialize the subdevice private data, but the same function subsequently dereferences the pointer to access the `next_time_min` and `next_time_max` members without checking it first. The other missing test is in the timer expiry routine `jr3_pci_poll_dev()`, but it will crash before it gets that far. Fix the bug by returning `-ENOMEM` from `jr3_pci_auto_attach()` as soon as one of the calls to `jr3_pci_alloc_spriv()` returns `NULL`. The COMEDI core will subsequently call `jr3_pci_detach()` to clean up. Signed-off-by:

USB: Proper handling of Race Condition when two USB class drivers try to call init_usb_class simultaneously commit 2f86a96b upstream. There is race condition when two USB class drivers try to call init_usb_class at the same time and leads to crash. code path: probe->usb_register_dev->init_usb_class To solve this, mutex locking has been added in init_usb_class() and destroy_usb_class(). As pointed by Alan, removed "if (usb_class)" test from destroy_usb_class() because usb_class can never be NULL there. Signed-off-by:

commit 31c5d192 upstream. This development kit has an FT4232 on it with a custom USB VID/PID. The FT4232 provides four UARTs, but only two are used. The UART 0 is used by the FlashPro5 programmer and UART 2 is connected to the SmartFusion2 CortexM3 SoC UART port. Note that the USB VID is registered to Actel according to Linux USB VID database, but that was acquired by Microsemi. Signed-off-by:

commit 5008efc8 upstream. The PJ4 inline asm sequence to write to cp15 cannot be built in Thumb-2 mode, due to the way it performs arithmetic on the program counter, so it is built in ARM mode instead. However, building C files in ARM mode under CONFIG_THUMB2_KERNEL is problematic, since the instrumentation performed by subsystems like ftrace does not expect having to deal with interworking branches. Since the sequence in question is simply a poor man's ISB instruction, let's use a straight 'isb' instead when building in Thumb2 mode. Thumb2 implies V7, so 'isb' should always be supported in that case. Acked-by:

commit 3089c1df upstream. The vm fault handler relies on the fact that the VMA owns a reference to the BO. However, once mmap_sem is released, other tasks are free to destroy the VMA, which can lead to the BO being freed. Fix two code paths where that can happen, both related to vm fault retries. Found via a lock debugging warning which flagged &bo->wu_mutex as locked while being destroyed. Fixes: cbe12e74 ("drm/ttm: Allow vm fault retries") Signed-off-by:

[ Upstream commit 242d3a49 ] For each netns (except init_net), we initialize its null entry in 3 places: 1) The template itself, as we use kmemdup() 2) Code around dst_init_metrics() in ip6_route_net_init() 3) ip6_route_dev_notify(), which is supposed to initialize it after loopback registers Unfortunately the last one still happens in a wrong order because we expect to initialize net->ipv6.ip6_null_entry->rt6i_idev to net->loopback_dev's idev, thus we have to do that after we add idev to loopback. However, this notifier has priority == 0 same as ipv6_dev_notf, and ipv6_dev_notf is registered after ip6_route_dev_notifier so it is called actually after ip6_route_dev_notifier. This is similar to commit 2f460933 ("ipv6: initialize route null entry in addrconf_init()") which fixes init_net. Fix it by picking a smaller priority for ip6_route_dev_notifier. Also, we have to release the refcnt accordingly when unregistering loopback_dev because device exit functions are called before subsys exit functions. Acked-by:

[ Upstream commit 2f460933 ] Andrey reported a crash on init_net.ipv6.ip6_null_entry->rt6i_idev since it is always NULL. This is clearly wrong, we have code to initialize it to loopback_dev, unfortunately the order is still not correct. loopback_dev is registered very early during boot, we lose a chance to re-initialize it in notifier. addrconf_init() is called after ip6_route_init(), which means we have no chance to correct it. Fix it by moving this initialization explicitly after ipv6_add_dev(init_net.loopback_dev) in addrconf_init(). Reported-by:

[ Upstream commit 7162fb24 ] Andrey found a way to trigger the WARN_ON_ONCE(delta < len) in skb_try_coalesce() using syzkaller and a filter attached to a TCP socket over loopback interface. I believe one issue with looped skbs is that tcp_trim_head() can end up producing skb with under estimated truesize. It hardly matters for normal conditions, since packets sent over loopback are never truncated. Bytes trimmed from skb->head should not change skb truesize, since skb->head is not reallocated.

commit 6183468a upstream. Similar to commit fcd2042e ("mwifiex: printk() overflow with 32-byte SSIDs"), we failed to account for the existence of 32-char SSIDs in our debugfs code. Unlike in that case though, we zeroed out the containing struct first, and I'm pretty sure we're guaranteed to have some padding after the 'ssid.ssid' and 'ssid.ssid_len' fields (the struct is 33 bytes long). So, this is the difference between: # cat /sys/kernel/debug/mwifiex/mlan0/info ... essid="0123456789abcdef0123456789abcdef " ... and the correct output: # cat /sys/kernel/debug/mwifiex/mlan0/info ... essid="0123456789abcdef0123456789abcdef" ...
