commit cfbb0d90 upstream. For the reinstall prevention, the code I had added compares the whole key. It turns out though that iwlwifi firmware doesn't provide the TKIP TX MIC key as it's not needed in client mode, and thus the comparison will always return false. For client mode, thus always zero out the TX MIC key part before doing the comparison in order to avoid accepting the reinstall of the key with identical encryption and RX MIC key, but not the same TX MIC key (since the supplicant provides the real one.)

commit fdf7cb41 upstream. When a key is reinstalled we can reset the replay counters etc. which can lead to nonce reuse and/or replay detection being impossible, breaking security properties, as described in the "KRACK attacks". In particular, CVE-2017-13080 applies to GTK rekeying that happened in firmware while the host is in D3, with the second part of the attack being done after the host wakes up. In this case, the wpa_supplicant mitigation isn't sufficient since wpa_supplicant doesn't know the GTK material. In case this happens, simply silently accept the new key coming from userspace but don't take any action on it since it's the same key; this keeps the PN replay counters intact. Signed-off-by:

commit 9e8c399a upstream. Commit 6f542ebe ("MIPS: Fix race on setting and getting cpu_online_mask") effectively reverted commit 8f46cca1 ("MIPS: SMP: Fix possibility of deadlock when bringing CPUs online") and thus has reinstated the possibility of deadlock. The commit was based on testing of kernel v4.4, where the CPU hotplug core code issued a BUG() if the starting CPU is not marked online when the boot CPU returns from __cpu_up. The commit fixes this race (in v4.4), but re-introduces the deadlock situation. As noted in the commit message, upstream differs in this area. Commit 8df3e07e ("cpu/hotplug: Let upcoming cpu bring itself fully up") adds a completion event in the CPU hotplug core code, making this race impossible. However, people were unhappy with relying on the core code to do the right thing. To address the issues both commits were trying to fix, add a second completion event in the MIPS smp hotplug path. It removes the possibility of a race, since the MIPS smp hotplug code now synchronises both the boot and secondary CPUs before they return to the hotplug core code. It also addresses the deadlock by ensuring that the secondary CPU is not marked online before it's counters are synchronised. This fix should also be backported to fix the race condition introduced by the backport of commit 8f46cca1 ("MIPS: SMP: Fix possibility of deadlock when bringing CPUs online"), through really that race only existed before commit 8df3e07e ("cpu/hotplug: Let upcoming cpu bring itself fully up").

commit 6f542ebe upstream. While testing cpu hoptlug (cpu down and up in loops) on kernel 4.4, it was observed that occasionally check for cpu online will fail in kernel/cpu.c, _cpu_up: https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux-stable.git/tree/kernel/cpu.c?h=v4.4.79#n485 518 /* Arch-specific enabling code. */ 519 ret = __cpu_up(cpu, idle); 520 521 if (ret != 0) 522 goto out_notify; 523 BUG_ON(!cpu_online(cpu)); Reason is race between start_secondary and _cpu_up. cpu_callin_map is set before cpu_online_mask. In __cpu_up, cpu_callin_map is waited for, but cpu online mask is not, resulting in race in which secondary processor started and set cpu_callin_map, but not yet set the online mask,resulting in above BUG being hit. Upstream differs in the area. cpu_online check is in bringup_wait_for_ap, which is after cpu reached AP_ONLINE_IDLE,where secondary passed its start function. Nonetheless, fix makes start_secondary safe and not depending on other locks throughout the code. It protects as well against cpu_online checks put in between sometimes in the future. Fix this by moving completion after all flags are set. Signed-off-by:

commit a00eeede upstream. If a secondary CPU failed to start, for any reason, the CPU requesting the secondary to start would get stuck in the loop waiting for the secondary to be present in the cpu_callin_map. Rather than that, use a completion event to signal that the secondary CPU has started and is waiting to synchronise counters. Since the CPU presence will no longer be marked in cpu_callin_map, remove the redundant test from arch_cpu_idle_dead(). Signed-off-by:

commit 6a6cba1d upstream. The default CM target field in the GCR_BASE register is encoded with 0 meaning memory & 1 being reserved. However the definitions we use for those bits effectively get these two values backwards - likely because they were copied from the definitions for the CM regions where the target is encoded differently. This results in use setting up GCR_BASE with the reserved target value by default, rather than targeting memory as intended. Although we currently seem to get away with this it's not a great idea to rely upon. Fix this by changing our macros to match the documentated target values. The incorrect encoding became used as of commit 9f98f3dd ("MIPS: Add generic CM probe & access code") in the Linux v3.15 cycle, and was likely carried forwards from older but unused code introduced by commit 39b8d525 ("[MIPS] Add support for MIPS CMP platform.") in the v2.6.26 cycle.

commit 3510c7aa upstream. The recent fix for adding rwsem nesting annotation was using the given "hop" argument as the lock subclass key. Although the idea itself works, it may trigger a kernel warning like: BUG: looking up invalid subclass: 8 .... since the lockdep has a smaller number of subclasses (8) than we currently allow for the hops there (10). The current definition is merely a sanity check for avoiding the too deep delivery paths, and the 8 hops are already enough. So, as a quick fix, just follow the max hops as same as the max lockdep subclasses. Fixes: 1f20f9ff ("ALSA: seq: Fix nested rwsem annotation for lockdep splat") Reported-by:

commit 132d358b upstream. The SYSEX event delivery in OSS sequencer emulation assumed that the event is encoded in the variable-length data with the straight buffering. This was the normal behavior in the past, but during the development, the chained buffers were introduced for carrying more data, while the OSS code was left intact. As a result, when a SYSEX event with the chained buffer data is passed to OSS sequencer port, it may end up with the wrong memory access, as if it were having a too large buffer. This patch addresses the bug, by applying the buffer data expansion by the generic snd_seq_dump_var_event() helper function. Reported-by:

commit b9dd05c7 upstream. When CONFIG_DEBUG_USER is enabled, it's possible for a user to deliberately trigger dump_instr() with a chosen kernel address. Let's avoid problems resulting from this by using get_user() rather than __get_user(), ensuring that we don't erroneously access kernel memory. So that we can use the same code to dump user instructions and kernel instructions, the common dumping code is factored out to __dump_instr(), with the fs manipulated appropriately in dump_instr() around calls to this.

commit 624f5ab8 upstream. syzkaller reported a NULL pointer dereference in asn1_ber_decoder(). It can be reproduced by the following command, assuming CONFIG_PKCS7_TEST_KEY=y: keyctl add pkcs7_test desc '' @s The bug is that if the data buffer is empty, an integer underflow occurs in the following check: if (unlikely(dp >= datalen - 1)) goto data_overrun_error; This results in the NULL data pointer being dereferenced. Fix it by checking for 'datalen - dp < 2' instead. Also fix the similar check for 'dp >= datalen - n' later in the same function. That one possibly could result in a buffer overread. The NULL pointer dereference was reproducible using the "pkcs7_test" key type but not the "asymmetric" key type because the "asymmetric" key type checks for a 0-length payload before calling into the ASN.1 decoder but the "pkcs7_test" key type does not.

commit a3c812f7 upstream. When calling keyctl_read() on a key of type "trusted", if the user-supplied buffer was too small, the kernel ignored the buffer length and just wrote past the end of the buffer, potentially corrupting userspace memory. Fix it by instead returning the size required, as per the documentation for keyctl_read(). We also don't even fill the buffer at all in this case, as this is slightly easier to implement than doing a short read, and either behavior appears to be permitted. It also makes it match the behavior of the "encrypted" key type. Fixes: d00a1c72 ("keys: add new trusted key-type") Reported-by:

V1->V2: - fixed broken error checks - some corrections to the commit message V2->V3: - variable name changes, to clarify what's happening - check (and possibly set) the NTB format later in the common bind code path Signed-off-by:

commit 298747b7 upstream. The current driver code is not checking for the error values returned by 'hp_wmi_dock_state()' and 'hp_wmi_tablet_state()' before passing the returned values down to 'input_report_switch()'. This error code is being translated to '1' in the input subsystem, reporting the wrong status. The biggest problem caused by this issue is that several laptops are wrongly reported by the driver as docked, preventing them to be put to sleep using the LID (and in most cases they are not even dockable). With this patch we create the report switches only if we are able to read the dock and tablet mode status correctly from ACPI. Signed-off-by:

[ Upstream commit 3a89eaa6 ] The support for DSA Ethernet switch chips depends on TCP/IP networking, thus explicit that HAVE_NET_DSA depends on INET. DSA uses SWITCHDEV, thus select it instead of depending on it. Signed-off-by:

[ Upstream commit 10340510 ] STARTLAN needs to be the first IPA command after MPC initialization completes. So move the qeth_send_startlan() call from the layer disciplines into the core path, right after the MPC handshake. While at it, replace the magic LAN OFFLINE return code with the existing enum.

[ Upstream commit 27d41d29 ] Since ipoib_cm_tx_start function and ipoib_cm_tx_reap function belong to different work queues, they can run in parallel. In this case if ipoib_cm_tx_reap calls list_del and release the lock, ipoib_cm_tx_start may acquire it and call list_del_init on the already deleted object. Changing list_del to list_del_init in ipoib_cm_tx_reap fixes the problem. Fixes: 839fcaba ("IPoIB: Connected mode experimental support") Signed-off-by:

[ Upstream commit 9723ddc8 ] This driver reports misc scan input events on the sensor's status register changes. But the event capability for them was not set in the device initialization, so these events were ignored. This change adds the missing event capability. Signed-off-by:

[ Upstream commit 08fea55e ] This driver reports input events on their interrupts which are triggered by the sensor's status register changes. But only single bit change is reported in the interrupt handler. So if there are multiple bits are changed at almost the same time, other press or release events are ignored. This fixes it by detecting all changed bits in the status register. Signed-off-by:
