2017-08-20ipv6: repair fib6 tree in failure caseWei Wang
In fib6_add(), it is possible that fib6_add_1() picks an intermediate node and sets the node's fn->leaf to NULL in order to add this new route. However, if fib6_add_rt2node() fails to add the new route for some reason, fn->leaf will be left as NULL and could potentially cause crash when fn->leaf is accessed in fib6_locate(). This patch makes sure fib6_repair_tree() is called to properly repair fn->leaf in the above failure case. Here is the syzkaller reported general protection fault in fib6_locate: kasan: CONFIG_KASAN_INLINE enabled kasan: GPF could be caused by NULL-ptr deref or user memory access general protection fault: 0000 [#1] SMP KASAN Modules linked in: CPU: 0 PID: 40937 Comm: syz-executor3 Not tainted Hardware name: Google Google Compute Engine/Google Compute Engine, BIOS Google 01/01/2011 task: ffff8801d7d64100 ti: ffff8801d01a0000 task.ti: ffff8801d01a0000 RIP: 0010:[<ffffffff82a3e0e1>] [<ffffffff82a3e0e1>] __ipv6_prefix_equal64_half include/net/ipv6.h:475 [inline] RIP: 0010:[<ffffffff82a3e0e1>] [<ffffffff82a3e0e1>] ipv6_prefix_equal include/net/ipv6.h:492 [inline] RIP: 0010:[<ffffffff82a3e0e1>] [<ffffffff82a3e0e1>] fib6_locate_1 net/ipv6/ip6_fib.c:1210 [inline] RIP: 0010:[<ffffffff82a3e0e1>] [<ffffffff82a3e0e1>] fib6_locate+0x281/0x3c0 net/ipv6/ip6_fib.c:1233 RSP: 0018:ffff8801d01a36a8 EFLAGS: 00010202 RAX: 0000000000000020 RBX: ffff8801bc790e00 RCX: ffffc90002983000 RDX: 0000000000001219 RSI: ffff8801d01a37a0 RDI: 0000000000000100 RBP: ffff8801d01a36f0 R08: 00000000000000ff R09: 0000000000000000 R10: 0000000000000003 R11: 0000000000000000 R12: 0000000000000001 R13: dffffc0000000000 R14: ffff8801d01a37a0 R15: 0000000000000000 FS: 00007f6afd68c700(0000) GS:ffff8801db400000(0000) knlGS:0000000000000000 CS: 0010 DS: 0000 ES: 0000 CR0: 0000000080050033 CR2: 00000000004c6340 CR3: 00000000ba41f000 CR4: 00000000001426f0 DR0: 0000000000000000 DR1: 0000000000000000 DR2: 0000000000000000 DR3: 0000000000000000 DR6: 00000000fffe0ff0 DR7: 0000000000000400 Stack: ffff8801d01a37a8 ffff8801d01a3780 ffffed003a0346f5 0000000c82a23ea0 ffff8800b7bd7700 ffff8801d01a3780 ffff8800b6a1c940 ffffffff82a23ea0 ffff8801d01a3920 ffff8801d01a3748 ffffffff82a223d6 ffff8801d7d64988 Call Trace: [<ffffffff82a223d6>] ip6_route_del+0x106/0x570 net/ipv6/route.c:2109 [<ffffffff82a23f9d>] inet6_rtm_delroute+0xfd/0x100 net/ipv6/route.c:3075 [<ffffffff82621359>] rtnetlink_rcv_msg+0x549/0x7a0 net/core/rtnetlink.c:3450 [<ffffffff8274c1d1>] netlink_rcv_skb+0x141/0x370 net/netlink/af_netlink.c:2281 [<ffffffff82613ddf>] rtnetlink_rcv+0x2f/0x40 net/core/rtnetlink.c:3456 [<ffffffff8274ad38>] netlink_unicast_kernel net/netlink/af_netlink.c:1206 [inline] [<ffffffff8274ad38>] netlink_unicast+0x518/0x750 net/netlink/af_netlink.c:1232 [<ffffffff8274b83e>] netlink_sendmsg+0x8ce/0xc30 net/netlink/af_netlink.c:1778 [<ffffffff82564aff>] sock_sendmsg_nosec net/socket.c:609 [inline] [<ffffffff82564aff>] sock_sendmsg+0xcf/0x110 net/socket.c:619 [<ffffffff82564d62>] sock_write_iter+0x222/0x3a0 net/socket.c:834 [<ffffffff8178523d>] new_sync_write+0x1dd/0x2b0 fs/read_write.c:478 [<ffffffff817853f4>] __vfs_write+0xe4/0x110 fs/read_write.c:491 [<ffffffff81786c38>] vfs_write+0x178/0x4b0 fs/read_write.c:538 [<ffffffff817892a9>] SYSC_write fs/read_write.c:585 [inline] [<ffffffff817892a9>] SyS_write+0xd9/0x1b0 fs/read_write.c:577 [<ffffffff82c71e32>] entry_SYSCALL_64_fastpath+0x12/0x17 Note: there is no "Fixes" tag as this seems to be a bug introduced very early.

2017-08-20net: ibm: emac: Fix some error handling path in 'emac_probe()'Christophe Jaillet
If 'irq_of_parse_and_map()' or 'of_address_to_resource()' fail, 'err' is known to be 0 at this point. So return -ENODEV instead in the first case and use 'of_iomap()' instead of the equivalent 'of_address_to_resource()/ioremap()' combinaison in the 2nd case. Doing so, the 'rsrc_regs' field of the 'emac_instance struct' becomes redundant and is removed. While at it, turn a 'err != 0' test into an equivalent 'err' to be more consistent.

2017-08-20bpf: fix double free from dev_map_notification()Daniel Borkmann
In the current code, dev_map_free() can still race with dev_map_notification(). In dev_map_free(), we remove dtab from the list of dtabs after we purged all entries from it. However, we don't do xchg() with NULL or the like, so the entry at that point is still pointing to the device. If a unregister notification comes in at the same time, we therefore risk a double-free, since the pointer is still present in the map, and then pushed again to __dev_map_entry_free(). All this is completely unnecessary. Just remove the dtab from the list right before the synchronize_rcu(), so all outstanding readers from the notifier list have finished by then, thus we don't need to deal with this corner case anymore and also wouldn't need to nullify dev entires. This is fine because we iterate over the map releasing all entries and therefore dev references anyway.

This definition in Makefile.dtbinst: export dtbinst-root ?= $(obj) should define and export dtbinst-root when handling the root dts directory, and do nothing in the subdirectories. However some shells, including dash, will not pass through environment variables whose name includes a hyphen. Usually GNU make does not use a shell to recurse, but if e.g. $(srctree) contains '~' it will use a shell here. Rename the variable to dtbinst_root.

2017-08-21Kbuild: use -fshort-wchar globallyArnd Bergmann
Commit 971a69db7dc0 ("Xen: don't warn about 2-byte wchar_t in efi") added the --no-wchar-size-warning to the Makefile to avoid this harmless warning: arm-linux-gnueabi-ld: warning: drivers/xen/efi.o uses 2-byte wchar_t yet the output is to use 4-byte wchar_t; use of wchar_t values across objects may fail Changing kbuild to use thin archives instead of recursive linking unfortunately brings the same warning back during the final link. The kernel does not use wchar_t string literals at this point, and xen does not use wchar_t at all (only efi_char16_t), so the flag has no effect, but as pointed out by Jan Beulich, adding a wchar_t string literal would be bad here. Since wchar_t is always defined as u16, independent of the toolchain default, always passing -fshort-wchar is correct and lets us remove the Xen specific hack along with fixing the warning.

2017-08-20Sanitize 'move_pages()' permission checksLinus Torvalds
The 'move_paghes()' system call was introduced long long ago with the same permission checks as for sending a signal (except using CAP_SYS_NICE instead of CAP_SYS_KILL for the overriding capability). That turns out to not be a great choice - while the system call really only moves physical page allocations around (and you need other capabilities to do a lot of it), you can check the return value to map out some the virtual address choices and defeat ASLR of a binary that still shares your uid. So change the access checks to the more common 'ptrace_may_access()' model instead. This tightens the access checks for the uid, and also effectively changes the CAP_SYS_NICE check to CAP_SYS_PTRACE, but it's unlikely that anybody really _uses_ this legacy system call any more (we hav ebetter NUMA placement models these days), so I expect nobody to notice.

2017-08-20iio: hid-sensor-trigger: Fix the race with user space powering up sensorsSrinivas Pandruvada
It has been reported for a while that with iio-sensor-proxy service the rotation only works after one suspend/resume cycle. This required a wait in the systemd unit file to avoid race. I found a Yoga 900 where I could reproduce this. The problem scenerio is: - During sensor driver init, enable run time PM and also set a auto-suspend for 3 seconds. This result in one runtime resume. But there is a check to avoid a powerup in this sequence, but rpm is active - User space iio-sensor-proxy tries to power up the sensor. Since rpm is active it will simply return. But sensors were not actually powered up in the prior sequence, so actaully the sensors will not work - After 3 seconds the auto suspend kicks If we add a wait in systemd service file to fire iio-sensor-proxy after 3 seconds, then now everything will work as the runtime resume will actually powerup the sensor as this is a user request. To avoid this: - Remove the check to match user requested state, this will cause a brief powerup, but if the iio-sensor-proxy starts immediately it will still work as the sensors are ON. - Also move the autosuspend delay to place when user requested turn off of sensors, like after user finished raw read or buffer disable Signed-off-by: Srinivas Pandruvada <srinivas.pandruvada@linux.intel.com> Tested-by: Bastien Nocera <hadess@hadess.net> Cc: <Stable@vger.kernel.org> Signed-off-by: Jonathan Cameron <Jonathan.Cameron@huawei.com>
