commit b299cde2 upstream. /dev/mem currently allows mmap() mappings that wrap around the end of the physical address space, which should probably be illegal. It circumvents the existing STRICT_DEVMEM permission check because the loop immediately terminates (as the start address is already higher than the end address). On the x86_64 architecture it will then cause a panic (from the BUG(start >= end) in arch/x86/mm/pat.c:reserve_memtype()). This patch adds an explicit check to make sure offset + size will not wrap around in the physical address type. Signed-off-by:

commit 6df2b42f upstream. We have one register for each EP to set the maximum packet size for both TX and RX. If for example an RX programming would happen before the previous TX transfer finishes we would reset the TX packet side. To fix this issue, only modify the TX or RX part of the register.

commit 346e9973 upstream. If a device is unplugged and replugged during Sx system suspend some Intel xHC hosts will overwrite the CAS (Cold attach status) flag and no device connection is noticed in resume. A device in this state can be identified in resume if its link state is in polling or compliance mode, and the current connect status is 0. A device in this state needs to be warm reset. Intel 100/c230 series PCH specification update Doc #332692-006 Errata #8 Observed on Cherryview and Apollolake as they go into compliance mode if LFPS times out during polling, and re-plugged devices are not discovered at resume.

commit 30e7d894 upstream. Enabling the tracer selftest triggers occasionally the warning in text_poke(), which warns when the to be modified page is not marked reserved. The reason is that the tracer selftest installs kprobes on functions marked __init for testing. These probes are removed after the tests, but that removal schedules the delayed kprobes_optimizer work, which will do the actual text poke. If the work is executed after the init text is freed, then the warning triggers. The bug can be reproduced reliably when the work delay is increased. Flush the optimizer work and wait for the optimizing/unoptimizing lists to become empty before returning from the kprobes tracer selftest. That ensures that all operations which were queued due to the probes removal have completed. Link: http://lkml.kernel.org/r/20170516094802.76a468bb@gandalf.local.homeSigned-off-by:

commit 5667c86a upstream. Mesh forwarding path checks for address extension mode to fetch appropriate proxied address and MPP address. Existing condition that looks for 6 address format is not strict enough so that frames with improper values are processed and invalid entries are added into MPP table. Fix that by adding a stricter check before processing the packet. Per IEEE Std 802.11s-2011 spec. Table 7-6g1 lists address extension mode 0x3 as reserved one. And also Table Table 9-13 does not specify 0x3 as valid address field. Fixes: 9b395bc3 ("mac80211: verify that skb data is present") Signed-off-by:

commit bec444cd upstream. Add missing sanity check on the non-SuperSpeed hub-descriptor length in order to avoid parsing and leaking two bytes of uninitialised slab data through sysfs removable-attributes (or a compound-device debug statement). Note that we only make sure that the DeviceRemovable field is always present (and specifically ignore the unused PortPwrCtrlMask field) in order to continue support any hubs with non-compliant descriptors. As a further safeguard, the descriptor buffer is also cleared. Fixes: 1da177e4 ("Linux-2.6.12-rc2") Signed-off-by:

commit ec963b41 upstream. Fix up the root-hub descriptor to accommodate the variable-length DeviceRemovable and PortPwrCtrlMask fields, while marking all ports as removable (and leaving the reserved bit zero unset).

commit bafbb9c7 upstream. tcp_ack() can call tcp_fragment() which may dededuct the value tp->fackets_out when MSS changes. When prior_fackets is larger than tp->fackets_out, tcp_clean_rtx_queue() can invoke tcp_update_reordering() with negative values. This results in absurd tp->reodering values higher than sysctl_tcp_max_reordering. Note that tcp_update_reordering indeeds sets tp->reordering to min(sysctl_tcp_max_reordering, metric), but because the comparison is signed, a negative metric always wins.

commit 8bfd1743 upstream. (Correction in this resend: fixed function name acer_sa5_271_workaround; fixed the always-true condition in the function; fixed description.) On the Acer Switch Alpha 12 (model number: SA5-271), the internal SSD may not get detected because the port_map and CAP.nr_ports combination causes the driver to skip the port that is actually connected to the SSD. More specifically, either all SATA ports are identified as DUMMY, or all ports get ``link down'' and never get up again. This problem occurs occasionally. When this problem occurs, CAP may hold a value of 0xC734FF00 or 0xC734FF01 and port_map may hold a value of 0x00 or 0x01. When this problem does not occur, CAP holds a value of 0xC734FF02 and port_map may hold a value of 0x07. Overriding the CAP value to 0xC734FF02 and port_map to 0x7 significantly reduces the occurrence of this problem. Link: https://bugzilla.kernel.org/attachment.cgi?id=253091Signed-off-by:

commit bb246681 upstream. Commit 557aaa7f ("ft232: support the ASYNC_LOW_LATENCY flag") enables unprivileged users to set the FTDI latency timer, but there was a logic flaw that skipped sending the corresponding USB control message to the device. Specifically, the device latency timer would not be updated until next open, something which was later also inadvertently broken by commit c19db4c9 ("USB: ftdi_sio: set device latency timeout at port probe"). A recent commit c6dce262 ("USB: serial: ftdi_sio: fix extreme low-latency setting") disabled the low-latency mode by default so we now need this fix to allow unprivileged users to again enable it.

commit b451e5d2 upstream. This patch fixes a bug in splitting an SKB during SACK processing. Specifically if an skb contains multiple packets and is only partially sacked in the higher sequences, tcp_match_sack_to_skb() splits the skb and marks the second fragment as SACKed. The current code further attempts rounding up the first fragment to MSS boundaries. But it misses a boundary condition when the rounded-up fragment size (pkt_len) is exactly skb size. Spliting such an skb is pointless and causses a kernel warning and aborts the SACK processing. This patch universally checks such over-split before calling tcp_fragment to prevent these unnecessary warnings. Fixes: adb92db8 ("tcp: Make SACK code to split only at mss boundaries") Signed-off-by:

commit 9b3eb541 upstream. When CONFIG_XFRM_SUB_POLICY=y, xfrm_dst stores a copy of the flowi for that dst. Unfortunately, the code that allocates and fills this copy doesn't care about what type of flowi (flowi, flowi4, flowi6) gets passed. In multiple code paths (from raw_sendmsg, from TCP when replying to a FIN, in vxlan, geneve, and gre), the flowi that gets passed to xfrm is actually an on-stack flowi4, so we end up reading stuff from the stack past the end of the flowi4 struct. Since xfrm_dst->origin isn't used anywhere following commit ca116922 ("xfrm: Eliminate "fl" and "pol" args to xfrm_bundle_ok()."), just get rid of it. xfrm_dst->partner isn't used either, so get rid of that too.

commit f991af3d upstream. The retry logic for netlink_attachskb() inside sys_mq_notify() is nasty and vulnerable: 1) The sock refcnt is already released when retry is needed 2) The fd is controllable by user-space because we already release the file refcnt so we when retry but the fd has been just closed by user-space during this small window, we end up calling netlink_detachskb() on the error path which releases the sock again, later when the user-space closes this socket a use-after-free could be triggered. Setting 'sock' to NULL here should be sufficient to fix it. Reported-by:

commit 1e38da30 upstream. The handling of the might_cancel queueing is not properly protected, so parallel operations on the file descriptor can race with each other and lead to list corruptions or use after free. Protect the context for these operations with a seperate lock. The wait queue lock cannot be reused for this because that would create a lock inversion scenario vs. the cancel lock. Replacing might_cancel with an atomic (atomic_t or atomic bit) does not help either because it still can race vs. the actual list operation. Reported-by:
