commit 7a2b9e6e upstream. Add parent device name to the name of devices on bus to avoid device names collisions for same client UUID available from different MEI heads. Namely this prevents sysfs collision under /sys/bus/mei/device/ In the device part leave just UUID other parameters that are required for device matching are not required here and are just bloating the name.

commit c1a1f273 upstream. This device presents itself as a USB hub with three attached devices: - An ACM serial port connected to the GPS module (not affected by this commit) - An FTDI serial port connected to the GPS module (1546:0502) - Another FTDI serial port connected to the ODIN-W2 radio module (1546:0503) This commit registers U-Blox's VID and the PIDs of the second and third devices.

commit b7aa39a2 upstream. The variable skb is released via kfree_skb() when the return value of _rtl92e_tx is not zero. However, after that, skb is accessed again to read its length, which may result in a use after free bug. This patch fixes the bug by moving the release operation to where skb is never used later.

The mainline commit 8fde12ca ("mm: prevent get_user_pages() from overflowing page refcount") was backported to 4.9.y stable as commit 2ed768cf. The backport however missed that in 4.9, there are several arch-specific gup.c versions with fast gup implementations, so these do not prevent refcount overflow. This is partially fixed for x86 in stable-only commit d73af797 ("x86, mm, gup: prevent get_page() race with munmap in paravirt guest"). This stable-only commit adds missing parts to x86 version, as well as s390 version, both taken from the SUSE SLES/openSUSE 4.12-based kernels. The remaining architectures with own gup.c are sparc, mips, sh. It's unlikely the known overflow scenario based on FUSE, which needs 140GB of RAM, is a problem for those architectures, and I don't feel confident enough to patch them. Signed-off-by:

As such, we may be missing all potential errors, like SMP FUNCTION FAILED, INVALID REQUEST FRAME LENGTH, etc., meaning the PHY control request has failed. In some scenarios we need to ensure the function result is accepted, so add a check for this. Tested-by:

[ Upstream commit 0ac234be ] The ghes code is careful to parse and round firmware's advertised memory requirements for CPER records, up to a maximum of 64K. However when ghes_estatus_pool_expand() does its work, it splits the requested size into PAGE_SIZE granules. This means if firmware generates 5K of CPER records, and correctly describes this in the table, __process_error() will silently fail as it is unable to allocate more than PAGE_SIZE. Switch the estatus pool to vmalloc() memory. On x86 vmalloc() memory may fault and be fixed up by vmalloc_fault(). To prevent this call vmalloc_sync_all() before an NMI handler could discover the memory. Signed-off-by:

Currently libsas does not support checking if this condition occurs, nor rectifying when it does. Such a condition is not at all common, however it has been seen on some pre-silicon environments where the initiator PHY only supports a 1.5 Gbit maximum linkrate, mated with 12G expander PHYs and 3/6G SATA phy. This patch adds support for checking and rectifying this condition during initial device discovery only. We do support checking min pathway connection rate during revalidation phase, when new devices can be detected in the topology. However we do not support in the case of the the user reprogramming PHY linkrates, such that min pathway condition is not met/maintained. A note on root port PHY rates: The libsas root port PHY rates calculation is broken. Libsas sets the rates (min, max, and current linkrate) of a root port to the same linkrate of the first PHY member of that same port. In doing so, it assumes that all other PHYs which subsequently join the port to have the same negotiated linkrate, when they could actually be different. In practice this doesn't happen, as initiator and expander PHYs are normally initialised with consistent min/max linkrates. This has not caused an issue so far, so leave alone for now. Tested-by:

[ Upstream commit d1f20c03 ] hb_timer might not start at all for a particular transport because its start is conditional. In a result a node is not sending heartbeats. Function sctp_transport_reset_hb_timer has two roles: - initial start of hb_timer for a given transport, - update expire date of hb_timer for a given transport. The function is optimized to update timer's expire only if it is before a new calculated one but this comparison is invalid for a timer which has not yet started. Such a timer has expire == 0 and if a new expire value is bigger than (MAX_JIFFIES / 2 + 2) then "time_before" macro will fail and timer will not start resulting in no heartbeat packets send by the node. This was found when association was initialized within first 5 mins after system boot due to jiffies init value which is near to MAX_JIFFIES. Test kernel version: 4.9.154 (ARCH=arm) hb_timer.expire = 0; //initialized, not started timer new_expire = MAX_JIFFIES / 2 + 2; //or more time_before(hb_timer.expire, new_expire) == false Fixes: ba6f5e33 ("sctp: avoid refreshing heartbeat timer too often") Reported-by:

[ Upstream commit 50c29366 ] Digging through the ioctls with Al because of the previous patches, we found that on 64-bit decnet's dn_dev_ioctl() is wrong, because struct ifreq::ifr_ifru is actually 24 bytes (not 16 as expected from struct sockaddr) due to the ifru_map and ifru_settings members. Clearly, decnet expects the ioctl to be called with a struct like struct ifreq_dn { char ifr_name[IFNAMSIZ]; struct sockaddr_dn ifr_addr; }; since it does struct ifreq *ifr = ...; struct sockaddr_dn *sdn = (struct sockaddr_dn *)&ifr->ifr_addr; This means that DN_IFREQ_SIZE is too big for what it wants on 64-bit, as it is sizeof(struct ifreq) - sizeof(struct sockaddr) + sizeof(struct sockaddr_dn) This assumes that sizeof(struct sockaddr) is the size of ifr_ifru but that isn't true. Fix this to use offsetof(struct ifreq, ifr_ifru). This indeed doesn't really matter much - the result is that we copy in/out 8 bytes more than we should on 64-bit platforms. In case the "struct ifreq_dn" lands just on the end of a page though it might lead to faults. As far as I can tell, it has been like this forever, so it seems very likely that nobody cares.

[ Upstream commit 52fbf113 ] gen_pool_alloc_algo() uses different allocation functions implementing different allocation algorithms. With gen_pool_first_fit_align() allocation function, the returned address should be aligned on the requested boundary. If chunk start address isn't aligned on the requested boundary, the returned address isn't aligned too. The only way to get properly aligned address is to initialize the pool with chunks aligned on the requested boundary. If want to have an ability to allocate buffers aligned on different boundaries (for example, 4K, 1MB, ...), the chunk start address should be aligned on the max possible alignment. This happens because gen_pool_first_fit_align() looks for properly aligned memory block without taking into account the chunk start address alignment. To fix this, we provide chunk start address to gen_pool_first_fit_align() and change its implementation such that it starts looking for properly aligned block with appropriate offset (exactly as is done in CMA).

[ Upstream commit b0f17570 ] Commit e39c0df1 ("pwm: Introduce the pwm_args concept") has changed the variable for the period for clps711x-pwm driver, so now pwm_get/set_period() works with pwm->state.period variable instead of pwm->args.period. This patch changes the period variable in other places where it is used. Signed-off-by:

[ Upstream commit 47918bc6 ] In update_lmb_associativity_index() we lookup dr_node using of_find_node_by_path() which takes a reference for us. In the non-error case we forget to drop the reference. Note that find_aa_index() does modify properties of the node, but doesn't need an extra reference held once it's returned. Signed-off-by:

[ Upstream commit 0deae39c ] When the watchdog timer is set in interrupt mode, it causes a machine check when it times out. The purpose of this mode is to ease debugging, not to crash the kernel and reboot the machine. This patch implements a special handling for that, in order to not crash the kernel if the watchdog times out while in interrupt or within the idle task. Signed-off-by:
