2019-12-01Bluetooth: Fix invalid-free in bcsp_close()Tomas Bortoli1-0/+3
commit cf94da6f502d8caecabd56b194541c873c8a7a3c upstream. Syzbot reported an invalid-free that I introduced fixing a memleak. bcsp_recv() also frees bcsp->rx_skb but never nullifies its value. Nullify bcsp->rx_skb every time it is freed.

2019-12-01cfg80211: call disconnect_wk when AP stopsJohannes Berg3-1/+5
[ Upstream commit e005bd7ddea06784c1eb91ac5bb6b171a94f3b05 ] Since we now prevent regulatory restore during STA disconnect if concurrent AP interfaces are active, we need to reschedule this check when the AP state changes. This fixes never doing a restore when an AP is the last interface to stop. Or to put it another way: we need to re-check after anything we check here changes.

2019-12-01ipv6: Fix handling of LLA with VRF and sockets bound to VRFDavid Ahern1-1/+2
[ Upstream commit c2027d1e17582903e368abf5d4838b22a98f2b7b ] A recent commit allows sockets bound to a VRF to receive ipv6 link local packets. However, it only works for UDP and worse TCP connection attempts to the LLA with the only listener bound to the VRF just hang where as before the client gets a reset and connection refused. Fix by adjusting ir_iif for LL addresses and packets received through a device enslaved to a VRF.

2019-12-01i2c: uniphier-f: fix timeout error after reading 8 bytesMasahiro Yamada1-3/+14
[ Upstream commit c2a653deaa81f5a750c0dfcbaf9f8e5195cbe4a5 ] I was totally screwed up in commit eaba68785c2d ("i2c: uniphier-f: fix race condition when IRQ is cleared"). Since that commit, if the number of read bytes is multiple of the FIFO size (8, 16, 24... bytes), the STOP condition could be issued twice, depending on the timing. If this happens, the controller will go wrong, resulting in the timeout error. It was more than 3 years ago when I wrote this driver, so my memory about this hardware was vague. Please let me correct the description in the commit log of eaba68785c2d. Clearing the IRQ status on exiting the IRQ handler is absolutely fine. This controller makes a pause while any IRQ status is asserted. If the IRQ status is cleared first, the hardware may start the next transaction before the IRQ handler finishes what it supposed to do. This partially reverts the bad commit with clear comments so that I will never repeat this mistake. I also investigated what is happening at the last moment of the read mode. The UNIPHIER_FI2C_INT_RF interrupt is asserted a bit earlier (by half a period of the clock cycle) than UNIPHIER_FI2C_INT_RB. I consulted a hardware engineer, and I got the following information: UNIPHIER_FI2C_INT_RF asserted at the falling edge of SCL at the 8th bit. UNIPHIER_FI2C_INT_RB asserted at the rising edge of SCL at the 9th (ACK) bit. In order to avoid calling uniphier_fi2c_stop() twice, check the latter interrupt. I also commented this because it is obscure hardware internal.

[ Upstream commit 149a96047237574b756d872007c006acd0cc6687 ] When attempting to setup up a gpio hog, device probing would repeatedly fail with -EPROBE_DEFERED errors. It was caused by a circular dependency between the gpio and pinctrl frameworks. If the gpio-ranges property is present in device tree, then the gpio framework will handle the gpio pin registration and eliminate the circular dependency.

2019-12-01cfg80211: Prevent regulatory restore during STA disconnect in concurrent ↵Sriram R1-1/+5
interfaces [ Upstream commit 113f3aaa81bd56aba02659786ed65cbd9cb9a6fc ] Currently when an AP and STA interfaces are active in the same or different radios, regulatory settings are restored whenever the STA disconnects. This restores all channel information including dfs states in all radios. For example, if an AP interface is active in one radio and STA in another, when radar is detected on the AP interface, the dfs state of the channel will be changed to UNAVAILABLE. But when the STA interface disconnects, this issues a regulatory disconnect hint which restores all regulatory settings in all the radios attached and thereby losing the stored dfs state on the other radio where the channel was marked as unavailable earlier. Hence prevent such regulatory restore whenever another active beaconing interface is present in the same or other radios.

2019-12-01vrf: mark skb for multicast or link-local as enslaved to VRFMike Manning1-10/+9
[ Upstream commit 6f12fa775530195a501fb090d092c637f32d0cc5 ] The skb for packets that are multicast or to a link-local address are not marked as being enslaved to a VRF, if they are received on a socket bound to the VRF. This is needed for ND and it is preferable for the kernel not to have to deal with the additional use-cases if ll or mcast packets are handled as enslaved. However, this does not allow service instances listening on unbound and bound to VRF sockets to distinguish the VRF used, if packets are sent as multicast or to a link-local address. The fix is for the VRF driver to also mark these skb as being enslaved to the VRF.

[ Upstream commit 9de30f3f7f4d31037cfbb7c787e1089c1944b3a7 ] In copy_result_to_user(), we first create a struct dlm_lock_result, which contains a struct dlm_lksb, the last member of which is a pointer to the lvb. Unfortunately, we copy the entire struct dlm_lksb to the result struct, which is then copied to userspace at the end of the function, leaking the contents of sb_lvbptr, which is a valid kernel pointer in some cases (indeed, later in the same function the data it points to is copied to userspace). It is an error to leak kernel pointers to userspace, as it undermines KASLR protections (see e.g. 65eea8edc31 ("floppy: Do not copy a kernel pointer to user memory in FDGETPRM ioctl") for another example of this).

2019-12-01btrfs: avoid link error with CONFIG_NO_AUTO_INLINEArnd Bergmann1-3/+3
[ Upstream commit 7e17916b35797396f681a3270245fd29c1e4c250 ] Note: this patch fixes a problem in a feature outside of btrfs ("kernel hacking: add a config option to disable compiler auto-inlining") and is applied ahead of time due to cross-subsystem dependencies. On 32-bit ARM with gcc-8, I see a link error with the addition of the CONFIG_NO_AUTO_INLINE option: fs/btrfs/super.o: In function `btrfs_statfs': super.c:(.text+0x67b8): undefined reference to `__aeabi_uldivmod' super.c:(.text+0x67fc): undefined reference to `__aeabi_uldivmod' super.c:(.text+0x6858): undefined reference to `__aeabi_uldivmod' super.c:(.text+0x6920): undefined reference to `__aeabi_uldivmod' super.c:(.text+0x693c): undefined reference to `__aeabi_uldivmod' fs/btrfs/super.o:super.c:(.text+0x6958): more undefined references to `__aeabi_uldivmod' follow So far this is the only file that shows the behavior, so I'd propose to just work around it by marking the functions as 'static inline' that normally get inlined here. The reference to __aeabi_uldivmod comes from a div_u64() which has an optimization for a constant division that uses a straight '/' operator when the result should be known to the compiler. My interpretation is that as we turn off inlining, gcc still expects the result to be constant but fails to use that constant value.

2019-12-01sched/fair: Don't increase sd->balance_interval on newidle balanceValentin Schneider1-2/+11
[ Upstream commit 3f130a37c442d5c4d66531b240ebe9abfef426b5 ] When load_balance() fails to move some load because of task affinity, we end up increasing sd->balance_interval to delay the next periodic balance in the hopes that next time we look, that annoying pinned task(s) will be gone. However, idle_balance() pays no attention to sd->balance_interval, yet it will still lead to an increase in balance_interval in case of pinned tasks. If we're going through several newidle balances (e.g. we have a periodic task), this can lead to a huge increase of the balance_interval in a very small amount of time. To prevent that, don't increase the balance interval when going through a newidle balance. This is a similar approach to what is done in commit 58b26c4c0257 ("sched: Increment cache_nice_tries only on periodic lb"), where we disregard newidle balance and rely on periodic balance for more stable results.

[ Upstream commit fe60faa5063822f2d555f4f326c7dd72a60929bf ] Before calling dev_hard_start_xmit(), upper layers tried to cook optimal skb list based on BQL budget. Problem is that GSO packets can end up comsuming more than the BQL budget. Breaking the loop is not useful, since requeued packets are ahead of any packets still in the qdisc. It is also more expensive, since next TX completion will push these packets later, while skbs are not in cpu caches. It is also a behavior difference with TSO packets, that can break the BQL limit by a large amount. Note that drivers should use __netdev_tx_sent_queue() in order to have optimal xmit_more support, and avoid useless atomic operations as shown in the following patch.

[ Upstream commit cf76c78595ca87548ca5e45c862ac9e0949c4687 ] ocfs2_read_blocks() and ocfs2_read_blocks_sync() are both used to read several blocks from disk. Currently, the input argument *bhs* can be NULL or NOT. It depends on the caller's behavior. If the function fails in reading blocks from disk, the corresponding bh will be assigned to NULL and put. Obviously, above process for non-NULL input bh is not appropriate. Because the caller doesn't even know its bhs are put and re-assigned. If buffer head is managed by caller, ocfs2_read_blocks and ocfs2_read_blocks_sync() should not evaluate it to NULL. It will cause caller accessing illegal memory, thus crash.

2019-12-01mm/memory_hotplug: make add_memory() take the device_hotplug_lockDavid Hildenbrand6-7/+32
[ Upstream commit 8df1d0e4a265f25dc1e7e7624ccdbcb4a6630c89 ] add_memory() currently does not take the device_hotplug_lock, however is aleady called under the lock from arch/powerpc/platforms/pseries/hotplug-memory.c drivers/acpi/acpi_memhotplug.c to synchronize against CPU hot-remove and similar. In general, we should hold the device_hotplug_lock when adding memory to synchronize against online/offline request (e.g. from user space) - which already resulted in lock inversions due to device_lock() and mem_hotplug_lock - see 30467e0b3be ("mm, hotplug: fix concurrent memory hot-add deadlock"). add_memory()/add_memory_resource() will create memory block devices, so this really feels like the right thing to do. Holding the device_hotplug_lock makes sure that a memory block device can really only be accessed (e.g. via .online/.state) from user space, once the memory has been fully added to the system. The lock is not held yet in drivers/xen/balloon.c arch/powerpc/platforms/powernv/memtrace.c drivers/s390/char/sclp_cmd.c drivers/hv/hv_balloon.c So, let's either use the locked variants or take the lock. Don't export add_memory_resource(), as it once was exported to be used by XEN, which is never built as a module. If somebody requires it, we also have to export a locked variant (as device_hotplug_lock is never exported).
