We change the initialization of the skb transmit buffer queues in the functions tipc_bcast_xmit() and tipc_rcast_xmit() to also initialize their spinlocks. This is needed because we may, during error conditions, need to call skb_queue_purge() on those queues further down the stack.

When gso_size reset to zero for the tail segment in skb_segment(), later in ipv6_gso_segment(), __skb_udp_tunnel_segment() and gre_gso_segment() we will get incorrect results (payload length, pcsum) for that segment. inet_gso_segment() already has a check for gso_size before calculating payload.

In commit fc922bb0 ("mlxsw: spectrum_router: Use one LPM tree for all virtual routers") I increased the scale of supported VRFs by having all of them share the same LPM tree. In order to avoid look-ups for prefix lengths that don't exist, each route removal would trigger an aggregation across all the active virtual routers to see which prefix lengths are in use and which aren't and structure the tree accordingly. With the way the data structures are currently laid out, this is a very expensive operation. When preformed repeatedly - due to the invocation of the abort mechanism - and with enough VRFs, this can result in a hung task. For now, avoid this optimization until it can be properly re-added in net-next.

while processing Rx = Ry instruction the verifier does regs[insn->dst_reg] = regs[insn->src_reg] which often clears write mark (when Ry doesn't have it) that was just set by check_reg_arg(Rx) prior to the assignment. That causes mark_reg_read() to keep marking Rx in this block as REG_LIVE_READ (since the logic incorrectly misses that it's screened by the write) and in many of its parents (until lucky write into the same Rx or beginning of the program). That causes is_state_visited() logic to miss many pruning opportunities. Furthermore mark_reg_read() logic propagates the read mark for BPF_REG_FP as well (though it's readonly) which causes harmless but unnecssary work during is_state_visited(). Note that do_propagate_liveness() skips FP correctly, so do the same in mark_reg_read() as well.

Commit 35e015e1 ("ipv6: fix net.ipv6.conf.all interface DAD handlers") was intended to affect accept_dad flag handling in such a way that DAD operation and mode on a given interface would be selected according to the maximum value of conf/{all,interface}/accept_dad. However, addrconf_dad_begin() checks for particular cases in which we need to skip DAD, and this check was modified in the wrong way. Namely, it was modified so that, if the accept_dad flag is 0 for the given interface *or* for all interfaces, DAD would be skipped. We have instead to skip DAD if accept_dad is 0 for the given interface *and* for all interfaces.

ppp_release() tries to ensure that netdevices are unregistered before decrementing the unit refcount and running ppp_destroy_interface(). This is all fine as long as the the device is unregistered by ppp_release(): the unregister_netdevice() call, followed by rtnl_unlock(), guarantee that the unregistration process completes before rtnl_unlock() returns. However, the device may be unregistered by other means (like ppp_nl_dellink()). If this happens right before ppp_release() calling rtnl_lock(), then ppp_release() has to wait for the concurrent unregistration code to release the lock. But rtnl_unlock() releases the lock before completing the device unregistration process. This allows ppp_release() to proceed and eventually call ppp_destroy_interface() before the unregistration process completes. Calling free_netdev() on this partially unregistered device will BUG(): ------------[ cut here ]------------ kernel BUG at net/core/dev.c:8141! invalid opcode: 0000 [#1] SMP CPU: 1 PID: 1557 Comm: pppd Not tainted 4.14.0-rc2+ #4 Hardware name: QEMU Standard PC (i440FX + PIIX, 1996), BIOS 1.10.2-1.fc26 04/01/2014 Call Trace: ppp_destroy_interface+0xd8/0xe0 [ppp_generic] ppp_disconnect_channel+0xda/0x110 [ppp_generic] ppp_unregister_channel+0x5e/0x110 [ppp_generic] pppox_unbind_sock+0x23/0x30 [pppox] pppoe_connect+0x130/0x440 [pppoe] SYSC_connect+0x98/0x110 ? do_fcntl+0x2c0/0x5d0 SyS_connect+0xe/0x10 entry_SYSCALL_64_fastpath+0x1a/0xa5 RIP: free_netdev+0x107/0x110 RSP: ffffc28a40573d88 ---[ end trace ed294ff0cc40eeff ]--- We could set the ->needs_free_netdev flag on PPP devices and move the ppp_destroy_interface() logic in the ->priv_destructor() callback.

There are three important fields that indicate the overall health and status of an array: dev_health, sync_ratio, and sync_action. They tell us the condition of the devices in the array, and the degree to which the array is synchronized. This commit fixes a condition that is reported incorrectly. When a member of the array is being rebuilt or a new device is added, the "recover" process is used to synchronize it with the rest of the array. When the process is complete, but the sync thread hasn't yet been reaped, it is possible for the state of MD to be: mddev->recovery = [ MD_RECOVERY_RUNNING MD_RECOVERY_RECOVER MD_RECOVERY_DONE ] curr_resync_completed = <max dev size> (but not MaxSector) and all rdevs to be In_sync. This causes the 'array_in_sync' output parameter that is passed to rs_get_progress() to be computed incorrectly and reported as 'false' -- or not in-sync. This in turn causes the dev_health status characters to be reported as all 'a', rather than the proper 'A'. This can cause erroneous output for several seconds at a time when tools will want to be checking the condition due to events that are raised at the end of a sync process. Fix this by properly calculating the 'array_in_sync' return parameter in rs_get_progress(). Also, remove an unnecessary intermediate 'recovery_cp' variable in rs_get_progress().

This could arguably be moved to the next merge window but it also seemed relatively harmless to include now. - Amlogic/meson had driver changes merged that required devicetree changes to avoid functional/performance regressions. I've already asked them to be more careful about this going forward, and making sure drivers are compatible with older DTs when they make these kind of changes.

security_inode_getsecurity() provides the text string value of a security attribute. It does not provide a "secctx". The code in xattr_getsecurity() that calls security_inode_getsecurity() and then calls security_release_secctx() happened to work because SElinux and Smack treat the attribute and the secctx the same way. It fails for cap_inode_getsecurity(), because that module has no secctx that ever needs releasing. It turns out that Smack is the one that's doing things wrong by not allocating memory when instructed to do so by the "alloc" parameter. The fix is simple enough. Change the security_release_secctx() to kfree() because it isn't a secctx being returned by security_inode_getsecurity(). Change Smack to allocate the string when told to do so. Note: this also fixes memory leaks for LSMs which implement inode_getsecurity but not release_secctx, such as capabilities.

Merge tag 'v4.14-rockchip-dts64fixes-1' of git://git.kernel.org/pub/scm/linux/kernel/git/mmind/linux-rockchip into fixes Adding the operating points on rk3368 like they were did not end up well for the boards as all of them are missing their cpu supplies, the OPPs actually need to follow the <target min max> format as the regulator is shared between both clusters and the one rk3368 board I have, somehow also doesn't like the higher opps at all - all of which I only realized after I brought my rk3368 board online again, after its bootloader broke. So we revert that OPP addition for now. And also two fixes for the mipi dsi controller on rk3399, which was referencing a clock to high up in the clock-tree so that an intermediate gate could be disabled inadvertently and also needs a clock for its area in the general register files of the rk3399 soc. * tag 'v4.14-rockchip-dts64fixes-1' of git://git.kernel.org/pub/scm/linux/kernel/git/mmind/linux-rockchip: arm64: dts: rockchip: add the grf clk for dw-mipi-dsi on rk3399 arm64: dts: rockchip: Correct MIPI DPHY PLL clock on rk3399 Revert "arm64: dts: rockchip: Add basic cpu frequencies for RK3368" Signed-off-by: NOlof Johansson <olof@lixom.net>

Before commit 9c5d760b ("mm: split gfp_mask and mapping flags into separate fields") the private_* fields of struct adrress_space were grouped together and using "ditto" in comments describing the last fields was correct. With introduction of gpf_mask between private_lock and private_list "ditto" references the wrong description. Fix it by using the elaborate description.

printk_ratelimit() invokes ___ratelimit() which may invoke a normal printk() (pr_warn() in this particular case) to warn about suppressed output. Given that printk_ratelimit() may be called from anywhere, that pr_warn() is dangerous - it may end up deadlocking the system. Fix ___ratelimit() by using deferred printk().
