2017-10-27xfs: evict CoW fork extents when performing finsert/fcollapseDarrick J. Wong
commit 3af423b03435c81036fa710623d3ae92fbe346a3 upstream. When we perform an finsert/fcollapse operation, cancel all the CoW extents for the affected file offset range so that they don't end up pointing to the wrong blocks.

2017-10-27KEYS: don't let add_key() update an uninstantiated keyDavid Howells
commit 60ff5b2f547af3828aebafd54daded44cfb0807a upstream. Currently, when passed a key that already exists, add_key() will call the key's ->update() method if such exists. But this is heavily broken in the case where the key is uninstantiated because it doesn't call __key_instantiate_and_link(). Consequently, it doesn't do most of the things that are supposed to happen when the key is instantiated, such as setting the instantiation state, clearing KEY_FLAG_USER_CONSTRUCT and awakening tasks waiting on it, and incrementing key->user->nikeys. It also never takes key_construction_mutex, which means that ->instantiate() can run concurrently with ->update() on the same key. In the case of the "user" and "logon" key types this causes a memory leak, at best. Maybe even worse, the ->update() methods of the "encrypted" and "trusted" key types actually just dereference a NULL pointer when passed an uninstantiated key. Change key_create_or_update() to wait interruptibly for the key to finish construction before continuing. This patch only affects *uninstantiated* keys. For now we still allow a negatively instantiated key to be updated (thereby positively instantiating it), although that's broken too (the next patch fixes it) and I'm not sure that anyone actually uses that functionality either. Here is a simple reproducer for the bug using the "encrypted" key type (requires CONFIG_ENCRYPTED_KEYS=y), though as noted above the bug pertained to more than just the "encrypted" key type: #include <stdlib.h> #include <unistd.h> #include <keyutils.h> int main(void) { int ringid = keyctl_join_session_keyring(NULL); if (fork()) { for (;;) { const char payload[] = "update user:foo 32"; usleep(rand() % 10000); add_key("encrypted", "desc", payload, sizeof(payload), ringid); keyctl_clear(ringid); } } else { for (;;) request_key("encrypted", "desc", "callout_info", ringid); } } It causes: BUG: unable to handle kernel NULL pointer dereference at 0000000000000018 IP: encrypted_update+0xb0/0x170 PGD 7a178067 P4D 7a178067 PUD 77269067 PMD 0 PREEMPT SMP CPU: 0 PID: 340 Comm: reproduce Tainted: G D 4.14.0-rc1-00025-g428490e38b2e #796 Hardware name: QEMU Standard PC (i440FX + PIIX, 1996), BIOS Bochs 01/01/2011 task: ffff8a467a39a340 task.stack: ffffb15c40770000 RIP: 0010:encrypted_update+0xb0/0x170 RSP: 0018:ffffb15c40773de8 EFLAGS: 00010246 RAX: 0000000000000000 RBX: ffff8a467a275b00 RCX: 0000000000000000 RDX: 0000000000000005 RSI: ffff8a467a275b14 RDI: ffffffffb742f303 RBP: ffffb15c40773e20 R08: 0000000000000000 R09: ffff8a467a275b17 R10: 0000000000000020 R11: 0000000000000000 R12: 0000000000000000 R13: 0000000000000000 R14: ffff8a4677057180 R15: ffff8a467a275b0f FS: 00007f5d7fb08700(0000) GS:ffff8a467f200000(0000) knlGS:0000000000000000 CS: 0010 DS: 0000 ES: 0000 CR0: 0000000080050033 CR2: 0000000000000018 CR3: 0000000077262005 CR4: 00000000001606f0 Call Trace: key_create_or_update+0x2bc/0x460 SyS_add_key+0x10c/0x1d0 entry_SYSCALL_64_fastpath+0x1f/0xbe RIP: 0033:0x7f5d7f211259 RSP: 002b:00007ffed03904c8 EFLAGS: 00000246 ORIG_RAX: 00000000000000f8 RAX: ffffffffffffffda RBX: 000000003b2a7955 RCX: 00007f5d7f211259 RDX: 00000000004009e4 RSI: 00000000004009ff RDI: 0000000000400a04 RBP: 0000000068db8bad R08: 000000003b2a7955 R09: 0000000000000004 R10: 000000000000001a R11: 0000000000000246 R12: 0000000000400868 R13: 00007ffed03905d0 R14: 0000000000000000 R15: 0000000000000000 Code: 77 28 e8 64 34 1f 00 45 31 c0 31 c9 48 8d 55 c8 48 89 df 48 8d 75 d0 e8 ff f9 ff ff 85 c0 41 89 c4 0f 88 84 00 00 00 4c 8b 7d c8 <49> 8b 75 18 4c 89 ff e8 24 f8 ff ff 85 c0 41 89 c4 78 6d 49 8b RIP: encrypted_update+0xb0/0x170 RSP: ffffb15c40773de8 CR2: 0000000000000018 Reported-by: Eric Biggers <ebiggers@google.com> Signed-off-by: David Howells <dhowells@redhat.com> cc: Eric Biggers <ebiggers@google.com> Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>

2017-10-27KEYS: encrypted: fix dereference of NULL user_key_payloadEric Biggers
commit 13923d0865ca96312197962522e88bc0aedccd74 upstream. A key of type "encrypted" references a "master key" which is used to encrypt and decrypt the encrypted key's payload. However, when we accessed the master key's payload, we failed to handle the case where the master key has been revoked, which sets the payload pointer to NULL. Note that request_key() *does* skip revoked keys, but there is still a window where the key can be revoked before we acquire its semaphore. Fix it by checking for a NULL payload, treating it like a key which was already revoked at the time it was requested. This was an issue for master keys of type "user" only. Master keys can also be of type "trusted", but those cannot be revoked.

2017-10-27clockevents/drivers/cs5535: Improve resilience to spurious interruptsDavid Kozub
commit eb39a7c0355393c5a8d930f342ad7a6231b552c4 upstream. The interrupt handler mfgpt_tick() is not robust versus spurious interrupts which happen before the clock event device is registered and fully initialized. The reason is that the safe guard against spurious interrupts solely checks for the clockevents shutdown state, but lacks a check for detached state. If the interrupt hits while the device is in detached state it passes the safe guard and dereferences the event handler call back which is NULL. Add the missing state check.

2017-10-27bus: mbus: fix window size calculation for 4GB windowsJan Luebbe
commit 2bbbd96357ce76cc45ec722c00f654aa7b189112 upstream. At least the Armada XP SoC supports 4GB on a single DRAM window. Because the size register values contain the actual size - 1, the MSB is set in that case. For example, the SDRAM window's control register's value is 0xffffffe1 for 4GB (bits 31 to 24 contain the size). The MBUS driver reads back each window's size from registers and calculates the actual size as (control_reg | ~DDR_SIZE_MASK) + 1, which overflows for 32 bit values, resulting in other miscalculations further on (a bad RAM window for the CESA crypto engine calculated by mvebu_mbus_setup_cpu_target_nooverlap() in my case). This patch changes the type in 'struct mbus_dram_window' from u32 to u64, which allows us to keep using the same register calculation code in most MBUS-using drivers (which calculate ->size - 1 again).

This is the first of three patches to improve the stack usage in this driver. It would be good to have this backported to stabl kernels to get all drivers in 'allmodconfig' below the 2048 byte limit so we can turn on the frame warning again globally, but I realize that the patch is larger than the normal limit for stable backports.

commit c6ebcedbab7ca78984959386012a17b21183e1a3 upstream. Commit b6c159a9cb69 ("i2c: ismt: Don't duplicate the receive length for block reads") broke I2C block reads. It aimed to fix normal SMBus block read, but changed the correct behavior of I2C block read in the process. According to Documentation/i2c/smbus-protocol, one vital difference between normal SMBus block read and I2C block read is that there is no byte count prefixed in the data sent on the wire: SMBus Block Read: i2c_smbus_read_block_data() S Addr Wr [A] Comm [A] S Addr Rd [A] [Count] A [Data] A [Data] A ...

commit 445ef61543da3db5b699f87fb0aa4f227165f6ed upstream. The sunxi musb has a bug where sometimes it will generate a babble error on device disconnect instead of a disconnect IRQ. When this happens the musb controller switches from host mode to device mode (it clears MUSB_DEVCTL_HM/MUSB_DEVCTL_SESSION and sets MUSB_DEVCTL_BDEVICE) and gets stuck in this state. The babble error is misdetected as a bus reset because MUSB_DEVCTL_HM was cleared. To fix this, use is_host_active() rather than (devctl & MUSB_DEVCTL_HM) to detect babble error so that sunxi musb babble recovery can handle it by restoring the mode. This information is provided by the driver logic and does not rely on register contents.

commit 6ed05c68cbcae42cd52b8e53b66952bfa9c002ce upstream. This fixes a kernel oops when unloading the driver due to usb_put_phy being called after usb_phy_generic_unregister when the device is detached. Calling usb_phy_generic_unregister causes x->dev->driver to be NULL in usb_put_phy and results in a NULL pointer dereference.

2017-10-27parisc: Fix double-word compare and exchange in LWS code on 32-bit kernelsJohn David Anglin
commit 374b3bf8e8b519f61eb9775888074c6e46b3bf0c upstream. As discussed on the debian-hppa list, double-wordcompare and exchange operations fail on 32-bit kernels. Looking at the code, I realized that the ",ma" completer does the wrong thing in the "ldw,ma 4(%r26), %r29" instruction. This increments %r26 and causes the following store to write to the wrong location.

commit 97819f943063b622eca44d3644067c190dc75039 upstream. If sending messages with no cable connected, it quickly happens that there is no more TX context available. Then "gs_can_start_xmit()" returns with "NETDEV_TX_BUSY" and the upper layer does retry immediately keeping the CPU busy. To fix that issue, I moved "atomic_dec(&dev->active_tx_urbs)" from "gs_usb_xmit_callback()" to the TX done handling in "gs_usb_receive_bulk_callback()". Renaming "active_tx_urbs" to "active_tx_contexts" and moving it into "gs_[alloc|free]_tx_context()" would also make sense.

commit 1ac7db63333db1eeff901bfd6bbcd502b4634fa4 upstream. If the connect status change is set during reset signaling, but the status remains connected just retry port reset. This solves an issue with connecting a 90W HP Thunderbolt 3 dock with a Lenovo Carbon x1 (5th generation) which causes a 30min loop of a high speed device being re-discovererd before usb ports starts working.

2017-10-27USB: devio: Revert "USB: devio: Don't corrupt user memory"Hans de Goede
commit 845d584f41eac3475c21e4a7d5e88d0f6e410cf7 upstream. Taking the uurb->buffer_length userspace passes in as a maximum for the actual urbs transfer_buffer_length causes 2 serious issues: 1) It breaks isochronous support for all userspace apps using libusb, as existing libusb versions pass in 0 for uurb->buffer_length, relying on the kernel using the lenghts of the usbdevfs_iso_packet_desc descriptors passed in added together as buffer length. This for example causes redirection of USB audio and Webcam's into virtual machines using qemu-kvm to no longer work. This is a userspace ABI break and as such must be reverted. Note that the original commit does not protect other users / the kernels memory, it only stops the userspace process making the call from shooting itself in the foot. 2) It may cause the kernel to program host controllers to DMA over random memory. Just as the devio code used to only look at the iso_packet_desc lenghts, the host drivers do the same, relying on the submitter of the urbs to make sure the entire buffer is large enough and not checking transfer_buffer_length. But the "USB: devio: Don't corrupt user memory" commit now takes the userspace provided uurb->buffer_length for the buffer-size while copying over the user-provided iso_packet_desc lengths 1:1, allowing the user to specify a small buffer size while programming the host controller to dma a lot more data. (Atleast the ohci, uhci, xhci and fhci drivers do not check transfer_buffer_length for isoc transfers.) This reverts commit fa1ed74eb1c2 ("USB: devio: Don't corrupt user memory") fixing both these issues.

commit 40d829fb2ec636b6b4b0cc95e2546ab9aca04cc9 upstream. The PIDs for Isochronous data transfers are incorrect for high bandwidth IN endpoints when the request length is less than EP wMaxPacketSize. As per spec correct PIDs for ISOC data transfers are: 1) For request length <= maxpacket - DATA0, 2) For maxpacket < length <= (2 * maxpacket) - DATA1, DATA0 3) For (2 * maxpacket) < length <= (3 * maxpacket) - DATA2, DATA1, DATA0. But driver always sets PCM fields based on wMaxPacketSize due to which DATA2 happens even for small requests. Fix this by setting the PCM field of trb->size depending on request length rather than fixing it to the value depending on wMaxPacketSize. Ideally it shouldn't give any issues as dwc3 will send 0-length packet for next IN token if host sends (even after receiving a short packet).

[ Upstream commit 3827b64dba27ebadb4faf51f2c91143e01ba1f6d ] After commit 66d228a2bf03 ("regulator: core: Don't use regulators as supplies until the parent is bound"), input supplies aren't resolved if the input supplies parent device has not been bound. This prevent regulators to hold an invalid reference if its supply parent device driver probe is deferred. But this causes issues on some boards where a PMIC's regulator use as input supply a regulator from another PMIC whose driver is registered after the driver for the former. In this case the regulators for the first PMIC will fail to resolve input supplies on regulators registration (since the other PMIC wasn't probed yet). And when the core attempts to resolve again latter when the other PMIC registers its own regulators, it will fail again since the parent device isn't bound yet. This will cause some parent supplies to never be resolved and wrongly be disabled on boot due taking them as unused. To solve this problem, also attempt to resolve the pending regulators input supplies before disabling the unused regulators.

2017-10-21ceph: clean up unsafe d_parent accesses in build_dentry_pathJeff Layton
[ Upstream commit c6b0b656ca24ede6657abb4a2cd910fa9c1879ba ] While we hold a reference to the dentry when build_dentry_path is called, we could end up racing with a rename that changes d_parent. Handle that situation correctly, by using the rcu_read_lock to ensure that the parent dentry and inode stick around long enough to safely check ceph_snap and ceph_ino.
