2017-12-01afs: Properly reset afs_vnode (inode) fieldsDavid Howells
When an AFS inode is allocated by afs_alloc_inode(), the allocated afs_vnode struct isn't necessarily reset from the last time it was used as an inode because the slab constructor is only invoked once when the memory is obtained from the page allocator. This means that information can leak from one inode to the next because we're not calling kmem_cache_zalloc(). Some of the information isn't reset, in particular the permit cache pointer. Bring the clearances up to date. Signed-off-by: David Howells <dhowells@redhat.com> Tested-by: Marc Dionne <marc.dionne@auristor.com>
2017-12-01afs: Fix permit refcountingDavid Howells
Fix four refcount bugs in afs_cache_permit(): (1) When checking the result of the kzalloc(), we can't just return, but must put 'permits'. (2) We shouldn't put permits immediately after hashing a new permit as we need to keep the pointer stable so that we can check to see if vnode->permit_cache has changed before we decide whether to assign to it. (3) 'permits' is being put twice. (4) We need to put either the replacement or the thing replaced after the assignment to vnode->permit_cache. Without this, lots of the following are seen: Kernel BUG at ffffffffa039857b [verbose debug info unavailable] ------------[ cut here ]------------ Kernel BUG at ffffffffa039858a [verbose debug info unavailable] ------------[ cut here ]------------ The addresses are in the .text..refcount section of the kafs.ko module. Following the relocation records for the __ex_table section shows one to be due to the decrement in afs_put_permits() and the other to be key_get() in afs_cache_permit(). Occasionally, the following is seen: refcount_t overflow at afs_cache_permit+0x57d/0x5c0 [kafs] in cc1[562], uid/euid: 0/0 WARNING: CPU: 0 PID: 562 at kernel/panic.c:657 refcount_error_report+0x9c/0xac ...

2017-12-01batman-adv: Fix check of retrieved orig_gw in batadv_v_gw_is_eligibleSven Eckelmann
The batadv_v_gw_is_eligible function already assumes that orig_node is not NULL. But batadv_gw_node_get may have failed to find the originator. It must therefore be checked whether the batadv_gw_node_get failed and not whether orig_node is NULL to detect this error. Fixes: 50164d8f500f ("batman-adv: B.A.T.M.A.N.

2017-12-01can: mcba_usb: fix device disconnect bugMartin Kelly
Currently, when you disconnect the device, the driver infinitely resubmits all URBs, so you see: Rx URB aborted (-32) in an infinite loop. Fix this by catching -EPIPE (what we get in urb->status when the device disconnects) and not resubmitting. With this patch, I can plug and unplug many times and the driver recovers correctly.

FlexCAN controller can be little or big endian on any architecture. For e.g. NXP LS1021A ARM based SOC has big endian FlexCAN controller. Therefore, the driver has been modified to add a provision for both types of controllers using an additional device tree property.

The GPIO interrupt controller however specifies the register offset without subtracting the "cbus" base address. This leads to a problem where of_iomap inside the irq-meson-gpio driver fails because it actually tries to map 0x182209880 (cbus base = 0xc1100000 + 0xc1109880 for the GPIO interrupt controller).
