2017-01-17ARM64: dts: meson-gxbb-odroidc2: Disable SCPI DVFSNeil Armstrong2-1/+5
The current hardware is not able to run with all cores enabled at a cluster frequency superior at 1536MHz. But the currently shipped u-boot for the platform still reports an OPP table with possible DVFS frequency up to 2GHz, and will not change since the off-tree linux tree supports limiting the OPPs with a kernel parameter. A recent u-boot change reports the boot-time DVFS around 100MHz and the default performance cpufreq governor sets the maximum frequency. Previous version of u-boot reported to be already at the max OPP and left the OPP as is. Nevertheless, other governors like ondemand could setup the max frequency and make the system crash. This patch disables the DVFS clock and disables cpufreq.

2017-01-17xfs: don't wrap ID in xfs_dq_get_next_idEric Sandeen1-0/+4
The GETNEXTQOTA ioctl takes whatever ID is sent in, and looks for the next active quota for an user equal or higher to that ID. But if we are at the maximum ID and then ask for the "next" one, we may wrap back to zero. In this case, userspace may loop forever, because it will start querying again at zero. We'll fix this in userspace as well, but for the kernel, return -ENOENT if we ask for the next quota ID past UINT_MAX so the caller knows to stop.

2017-01-17xfs: sanity check inode mode when creating new dentryAmir Goldstein1-9/+39
The helper xfs_dentry_to_name() is used by 2 different classes of callers: Callers that pass zero mode and don't care about the returned name.type field and Callers that pass non zero mode and do care about the name.type field. Change xfs_dentry_to_name() to not take the mode argument and change the call sites of the first class to not pass the mode argument. Create a new helper xfs_dentry_mode_to_name() which does pass the mode argument and returns -EFSCORRUPTED if mode is invalid. Callers that translate non zero mode to on-disk file type now check the return value and will export the error to user instead of staging an invalid file type to be written to directory entry.

2017-01-17xfs: sanity check directory inode di_sizeAmir Goldstein2-3/+7
This changes fixes an assertion hit when fuzzing on-disk i_mode values. The easy case to fix is when changing an empty file i_mode to S_IFDIR. In this case, xfs_dinode_verify() detects an illegal zero size for directory and fails to load the inode structure from disk. For the case of non empty file whose i_mode is changed to S_IFDIR, the ASSERT() statement in xfs_dir2_isblock() is replaced with return -EFSCORRUPTED, to avoid interacting with corrupted jusk also when XFS_DEBUG is disabled.

2017-01-17scsi: mpt3sas: fix hang on ata passthrough commandsJames Bottomley2-14/+38
mpt3sas has a firmware failure where it can only handle one pass through ATA command at a time. If another comes in, contrary to the SAT standard, it will hang until the first one completes (causing long commands like secure erase to timeout). The original fix was to block the device when an ATA command came in, but this caused a regression with commit 669f044170d8933c3d66d231b69ea97cb8447338 Author: Bart Van Assche <[email protected]> Date: Tue Nov 22 16:17:13 2016 -0800 scsi: srp_transport: Move queuecommand() wait code to SCSI core So fix the original fix of the secure erase timeout by properly returning SAM_STAT_BUSY like the SAT recommends.

emulator_fix_hypercall() replaces hypercall with vmcall instruction, but it does not handle GP exception properly when writes the new instruction. It can return X86EMUL_PROPAGATE_FAULT without setting exception information. This leads to incorrect emulation and triggers WARN_ON(ctxt->exception.vector > 0x1f) in x86_emulate_insn() as discovered by syzkaller fuzzer: WARNING: CPU: 2 PID: 18646 at arch/x86/kvm/emulate.c:5558 Call Trace: warn_slowpath_null+0x2c/0x40 kernel/panic.c:582 x86_emulate_insn+0x16a5/0x4090 arch/x86/kvm/emulate.c:5572 x86_emulate_instruction+0x403/0x1cc0 arch/x86/kvm/x86.c:5618 emulate_instruction arch/x86/include/asm/kvm_host.h:1127 [inline] handle_exception+0x594/0xfd0 arch/x86/kvm/vmx.c:5762 vmx_handle_exit+0x2b7/0x38b0 arch/x86/kvm/vmx.c:8625 vcpu_enter_guest arch/x86/kvm/x86.c:6888 [inline] vcpu_run arch/x86/kvm/x86.c:6947 [inline] Set exception information when write in emulator_fix_hypercall() fails.

2017-01-17ubifs: Fix journal replay wrt. xattr nodesRichard Weinberger1-2/+23
When replaying the journal it can happen that a journal entry points to a garbage collected node. This is the case when a power-cut occurred between a garbage collect run and a commit. In such a case nodes have to be read using the failable read functions to detect whether the found node matches what we expect. One corner case was forgotten, when the journal contains an entry to remove an inode all xattrs have to be removed too. UBIFS models xattr like directory entries, so the TNC code iterates over all xattrs of the inode and removes them too. This code re-uses the functions for walking directories and calls ubifs_tnc_next_ent(). ubifs_tnc_next_ent() expects to be used only after the journal and aborts when a node does not match the expected result. This behavior can render an UBIFS volume unmountable after a power-cut when xattrs are used. Fix this issue by using failable read functions in ubifs_tnc_next_ent() too when replaying the journal.

2017-01-17ubifs: remove redundant checks for encryption keyEric Biggers1-55/+3
In several places, ubifs checked for an encryption key before creating a file in an encrypted directory. This was redundant with fscrypt_setup_filename() or ubifs_new_inode(), and in the case of ubifs_link() it broke linking to special files. So remove the extra checks.

2017-01-17ubifs: allow encryption ioctls in compat modeEric Biggers1-0/+3
The ubifs encryption ioctls did not work when called by a 32-bit program on a 64-bit kernel. Since 'struct fscrypt_policy' is not affected by the word size, ubifs just needs to allow these ioctls through, like what ext4 and f2fs do.

2017-01-17ubifs: add CONFIG_BLOCK dependency for encryptionArnd Bergmann1-1/+1
This came up during the v4.10 merge window: warning: (UBIFS_FS_ENCRYPTION) selects FS_ENCRYPTION which has unmet direct dependencies (BLOCK) fs/crypto/crypto.c: In function 'fscrypt_zeroout_range': fs/crypto/crypto.c:355:9: error: implicit declaration of function 'bio_alloc';did you mean 'd_alloc'? [-Werror=implicit-function-declaration] bio = bio_alloc(GFP_NOWAIT, 1); The easiest way out is to limit UBIFS_FS_ENCRYPTION to configurations that also enable BLOCK.
