2017-11-02arm64: Don't walk page table for user faults in do_mem_abortWill Deacon
Commit 42dbf54e8890 ("arm64: consistently log ESR and page table") dumps page table entries for user faults hitting do_bad entries in the fault handler table. Whilst this shouldn't really happen in practice, it's not beyond the realms of possibility if e.g. running an old kernel on a new CPU. Generally, we want to avoid exposing physical addresses under the control of userspace (see commit bf396c09c24 ("arm64: mm: don't print out page table entries on EL0 faults")), so walk the page tables only on exceptions from EL1.

Commit 2ba8444c97b1 ("staging:r8188eu: move IV/ICV trimming into decrypt() and also place it after rtl88eu_mon_recv_hook()") breaks ARP. After this commit ssh-ing to a laptop with r8188eu wifi no longer works if the machine connecting has never communicated with the laptop before.

Commit 79650ffde38e ("staging:r8188eu: trim IV/ICV fields in validate_recv_data_frame()") This commit depends on 2 of the other commits being reverted. 2.

Note the same check, but now to actually continue doing ... instead of to not do it, so this commit is no good. 3.

2017-11-02xfrm: defer daddr pointer assignment after spi parsingFlorian Westphal
syzbot reports: BUG: KASAN: use-after-free in __xfrm_state_lookup+0x695/0x6b0 Read of size 4 at addr ffff8801d434e538 by task syzkaller647520/2991 [..] __xfrm_state_lookup+0x695/0x6b0 net/xfrm/xfrm_state.c:833 xfrm_state_lookup+0x8a/0x160 net/xfrm/xfrm_state.c:1592 xfrm_input+0x8e5/0x22f0 net/xfrm/xfrm_input.c:302 The use-after-free is the ipv4 destination address, which points to an skb head area that has been reallocated: pskb_expand_head+0x36b/0x1210 net/core/skbuff.c:1494 __pskb_pull_tail+0x14a/0x17c0 net/core/skbuff.c:1877 pskb_may_pull include/linux/skbuff.h:2102 [inline] xfrm_parse_spi+0x3d3/0x4d0 net/xfrm/xfrm_input.c:170 xfrm_input+0xce2/0x22f0 net/xfrm/xfrm_input.c:291 so the real bug is that xfrm_parse_spi() uses pskb_may_pull, but for now do smaller workaround that makes xfrm_input fetch daddr after spi parsing.
