2017-11-15MIPS: SMP: Use a completion event to signal CPU upMatt Redfearn
commit a00eeede507c975087b7b8df8cf2c9f88ba285de 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: Matt Redfearn <matt.redfearn@imgtec.com> Cc: Maciej W.

2017-11-15MIPS: Fix CM region target definitionsPaul Burton
commit 6a6cba1d945a7511cdfaf338526871195e420762 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 9f98f3dd0c51 ("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 39b8d5254246 ("[MIPS] Add support for MIPS CMP platform.") in the v2.6.26 cycle.

2017-11-15ALSA: seq: Avoid invalid lockdep class warningTakashi Iwai
commit 3510c7aa069aa83a2de6dab2b41401a198317bdc 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.

2017-11-15ALSA: seq: Fix OSS sysex delivery in OSS emulationTakashi Iwai
commit 132d358b183ac6ad8b3fea32ad5e0663456d18d1 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.

commit b9dd05c7002ee0ca8b676428b2268c26399b5e31 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.

2017-11-15KEYS: fix NULL pointer dereference during ASN.1 parsing [ver #2]Eric Biggers
commit 624f5ab8720b3371367327a822c267699c1823b8 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. The bug report was: BUG: unable to handle kernel NULL pointer dereference at (null) IP: asn1_ber_decoder+0x17f/0xe60 lib/asn1_decoder.c:233 PGD 7b708067 P4D 7b708067 PUD 7b6ee067 PMD 0 Oops: 0000 [#1] SMP Modules linked in: CPU: 0 PID: 522 Comm: syz-executor1 Not tainted 4.14.0-rc8 #7 Hardware name: QEMU Standard PC (i440FX + PIIX, 1996), BIOS 1.10.3-20171021_125229-anatol 04/01/2014 task: ffff9b6b3798c040 task.stack: ffff9b6b37970000 RIP: 0010:asn1_ber_decoder+0x17f/0xe60 lib/asn1_decoder.c:233 RSP: 0018:ffff9b6b37973c78 EFLAGS: 00010216 RAX: 0000000000000000 RBX: 0000000000000000 RCX: 000000000000021c RDX: ffffffff814a04ed RSI: ffffb1524066e000 RDI: ffffffff910759e0 RBP: ffff9b6b37973d60 R08: 0000000000000001 R09: ffff9b6b3caa4180 R10: 0000000000000000 R11: 0000000000000000 R12: 0000000000000002 R13: 0000000000000000 R14: 0000000000000000 R15: 0000000000000000 FS: 00007f10ed1f2700(0000) GS:ffff9b6b3ea00000(0000) knlGS:0000000000000000 CS: 0010 DS: 0000 ES: 0000 CR0: 0000000080050033 CR2: 0000000000000000 CR3: 000000007b6f3000 CR4: 00000000000006f0 Call Trace: pkcs7_parse_message+0xee/0x240 crypto/asymmetric_keys/pkcs7_parser.c:139 verify_pkcs7_signature+0x33/0x180 certs/system_keyring.c:216 pkcs7_preparse+0x41/0x70 crypto/asymmetric_keys/pkcs7_key_type.c:63 key_create_or_update+0x180/0x530 security/keys/key.c:855 SYSC_add_key security/keys/keyctl.c:122 [inline] SyS_add_key+0xbf/0x250 security/keys/keyctl.c:62 entry_SYSCALL_64_fastpath+0x1f/0xbe RIP: 0033:0x4585c9 RSP: 002b:00007f10ed1f1bd8 EFLAGS: 00000216 ORIG_RAX: 00000000000000f8 RAX: ffffffffffffffda RBX: 00007f10ed1f2700 RCX: 00000000004585c9 RDX: 0000000020000000 RSI: 0000000020008ffb RDI: 0000000020008000 RBP: 0000000000000000 R08: ffffffffffffffff R09: 0000000000000000 R10: 0000000000000000 R11: 0000000000000216 R12: 00007fff1b2260ae R13: 00007fff1b2260af R14: 00007f10ed1f2700 R15: 0000000000000000 Code: dd ca ff 48 8b 45 88 48 83 e8 01 4c 39 f0 0f 86 a8 07 00 00 e8 53 dd ca ff 49 8d 46 01 48 89 85 58 ff ff ff 48 8b 85 60 ff ff ff <42> 0f b6 0c 30 89 c8 88 8d 75 ff ff ff 83 e0 1f 89 8d 28 ff ff RIP: asn1_ber_decoder+0x17f/0xe60 lib/asn1_decoder.c:233 RSP: ffff9b6b37973c78 CR2: 0000000000000000 Fixes: 42d5ec27f873 ("X.509: Add an ASN.1 decoder") Reported-by: syzbot <syzkaller@googlegroups.com> Signed-off-by: Eric Biggers <ebiggers@google.com> Signed-off-by: David Howells <dhowells@redhat.com> Signed-off-by: James Morris <james.l.morris@oracle.com> Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>

2017-11-15KEYS: trusted: fix writing past end of buffer in trusted_read()Eric Biggers
commit a3c812f7cfd80cf51e8f5b7034f7418f6beb56c1 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.

commit 298747b7579f5bbbced793d997b333fd10a24921 upstream.

2017-11-15IPsec: do not ignore crypto err in ah4 inputGilad Ben-Yossef
[ Upstream commit ebd89a2d0675f1325c2be5b7576fd8cb7e8defd0 ] ah4 input processing uses the asynchronous hash crypto API which supplies an error code as part of the operation completion but the error code was being ignored. Treat a crypto API error indication as a verification failure. While a crypto API reported error would almost certainly result in a memcpy of the digest failing anyway and thus the security risk seems minor, performing a memory compare on what might be uninitialized memory is wrong.

[ Upstream commit 10e840dfb0b7fc345082dd9e5fff3c1c02e7690e ] These stand-alone trigger drivers were using iio_trigger_put() where they should have been using iio_trigger_free(). The iio_trigger_put() adds a module_put which is bad since they never did a module_get. In the sysfs driver, module_get/put's are used as triggers are added & removed. This extra module_put() occurs on an error path in the probe routine (probably rare). In the bfin-timer & interrupt trigger drivers, the module resources are not explicitly managed, so it's doing a put on something that was never get'd. It occurs on the probe error path and on the remove path (not so rare). Tested with the sysfs trigger driver. The bfin & interrupt drivers were build tested & inspected only.

2017-11-15adv7604: Initialize drive strength to default when using DTLars-Peter Clausen
[ Upstream commit da8892d410db224d9a24104529794e6e37e0c100 ] The adv7604 driver platform data contains fields for configuring the drive strength of the output pins. When probing the driver through DT these fields are not explicitly initialized, which means they are left at 0. This is a reserved setting for the drive strength configuration though and can cause signal integrity issues. Whether these signal integrity issues are visible depends on the PCB specifics (e.g. the higher the load capacitance for the output the more visible the issue). But it has been observed on existing solutions at high pixel clock rates. Initialize the drive strength settings to the power-on-reset value of the device when probing through devicetree to avoid this issue.

[ Upstream commit 22aadb91c0a0055935109c175f5446abfb130702 ] The function hai_dump_data_field will do a stack buffer overrun when cat'ing /sys/fs/lustre/.../hsm/actions if an action has some data in it. hai_dump_data_field uses snprintf. But there is no check for truncation, and the value returned by snprintf is used as-is. The coordinator code calls hai_dump_data_field with 12 bytes in the buffer. The 6th byte of data is printed incompletely to make room for the terminating NUL. However snprintf still returns 2, so when hai_dump_data_field writes the final NUL, it does it outside the reserved buffer, in the 13th byte of the buffer. This stack buffer overrun hangs my VM. Fix by checking that there is enough room for the next 2 characters plus the NUL terminator. Don't print half bytes. Change the format to 02X instead of .2X, which makes more sense.

[ Upstream commit a93151a72061e944a4915458b1b1d6d505c03bbf ] If the driver is built as a module, autoload won't work because the module alias information is not filled. So user-space can't match the registered device with the corresponding module. Export the module alias information using the MODULE_DEVICE_TABLE() macro. Before this patch: $ modinfo drivers/platform/x86/intel_mid_thermal.ko | grep alias $ After this patch: $ modinfo drivers/platform/x86/intel_mid_thermal.ko | grep alias alias: platform:msic_thermal Signed-off-by: Javier Martinez Canillas <javier@osg.samsung.com> Signed-off-by: Andy Shevchenko <andriy.shevchenko@linux.intel.com> Signed-off-by: Sasha Levin <alexander.levin@verizon.com> Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>
