PR_GET_SPECULATION_CTRL returns the state of the speculation misfeature which is selected with arg2 of prctl(2). The return value uses bit 0-2 with the following meaning: Bit Define Description 0 PR_SPEC_PRCTL Mitigation can be controlled per task by PR_SET_SPECULATION_CTRL 1 PR_SPEC_ENABLE The speculation feature is enabled, mitigation is disabled 2 PR_SPEC_DISABLE The speculation feature is disabled, mitigation is enabled If all bits are 0 the CPU is not affected by the speculation misfeature. If PR_SPEC_PRCTL is set, then the per task control of the mitigation is available. If not set, prctl(PR_SET_SPECULATION_CTRL) for the speculation misfeature will fail. PR_SET_SPECULATION_CTRL allows to control the speculation misfeature, which is selected by arg2 of prctl(2) per task. arg3 is used to hand in the control value, i.e. either PR_SPEC_ENABLE or PR_SPEC_DISABLE. The common return values are: EINVAL prctl is not implemented by the architecture or the unused prctl() arguments are not 0 ENODEV arg2 is selecting a not supported speculation misfeature PR_SET_SPECULATION_CTRL has these additional return values: ERANGE arg3 is incorrect, i.e. it's not either PR_SPEC_ENABLE or PR_SPEC_DISABLE ENXIO prctl control of the selected speculation misfeature is disabled The first supported controlable speculation misfeature is PR_SPEC_STORE_BYPASS. Add the define so this can be shared between architectures. Based on an initial patch from Tim Chen and mostly rewritten.

Intel refers to this feature as "Memory Disambiguation" which is part of their "Smart Memory Access" capability. Memory Disambiguation can expose a cache side-channel attack against such speculatively read values. An attacker can create exploit code that allows them to read memory outside of a sandbox environment (for example, malicious JavaScript in a web page), or to perform more complex attacks against code running within the same privilege level, e.g. via the stack. As a first step to mitigate against such attacks, provide two boot command line control knobs: nospec_store_bypass_disable spec_store_bypass_disable=[off,auto,on] By default affected x86 processors will power on with Speculative Store Bypass enabled. Hence the provided kernel parameters are written from the point of view of whether to enable a mitigation or not. The parameters are as follows: - auto - Kernel detects whether your CPU model contains an implementation of Speculative Store Bypass and picks the most appropriate mitigation. - on - disable Speculative Store Bypass - off - enable Speculative Store Bypass [ tglx: Reordered the checks so that the whole evaluation is not done when the CPU does not support RDS ] Signed-off-by: Konrad Rzeszutek Wilk <konrad.wilk@oracle.com> Signed-off-by: Thomas Gleixner <tglx@linutronix.de> Reviewed-by: Borislav Petkov <bp@suse.de> Reviewed-by: Ingo Molnar <mingo@kernel.org> Signed-off-by: David Woodhouse <dwmw@amazon.co.uk> Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org> Signed-off-by: Srivatsa S.

It does not do much except show the words 'Vulnerable' for recent x86 cores. Intel cores prior to family 6 are known not to be vulnerable, and so are some Atoms and some Xeon Phi. It assumes that older Cyrix, Centaur, etc. cores are immune.

However, many low-end mobile devices have older CPUs that don't have AES instructions, e.g. the ARMv8 Cryptography Extensions. Currently, user data on such devices is not encrypted at rest because AES is too slow, even when the NEON bit-sliced implementation of AES is used. Unfortunately, it is infeasible to encrypt these devices at all when AES is the only option. Therefore, this patch updates fscrypt to support the Speck block cipher, which was recently added to the crypto API. The C implementation of Speck is not especially fast, but Speck can be implemented very efficiently with general-purpose vector instructions, e.g. ARM NEON. For example, on an ARMv7 processor, we measured the NEON-accelerated Speck128/256-XTS at 69 MB/s for both encryption and decryption, while AES-256-XTS with the NEON bit-sliced implementation was only 22 MB/s encryption and 19 MB/s decryption. There are multiple variants of Speck. This patch only adds support for Speck128/256, which is the variant with a 128-bit block size and 256-bit key size -- the same as AES-256. This is believed to be the most secure variant of Speck, and it's only about 6% slower than Speck128/128. Speck64/128 would be at least 20% faster because it has 20% rounds, and it can be even faster on CPUs that can't efficiently do the 64-bit operations needed for Speck128. However, Speck64's 64-bit block size is not preferred security-wise. ARM NEON also supports the needed 64-bit operations even on 32-bit CPUs, resulting in Speck128 being fast enough for our targeted use cases so far. The chosen modes of operation are XTS for contents and CTS-CBC for filenames. These are the same modes of operation that fscrypt defaults to for AES. Note that as with the other fscrypt modes, Speck will not be used unless userspace chooses to use it. Nor are any of the existing modes (which are all AES-based) being removed, of course. We intentionally don't make CONFIG_FS_ENCRYPTION select CONFIG_CRYPTO_SPECK, so people will have to enable Speck support themselves if they need it. This is because we shouldn't bloat the FS_ENCRYPTION dependencies with every new cipher, especially ones that aren't recommended for most users. Moreover, CRYPTO_SPECK is just the generic implementation, which won't be fast enough for many users; in practice, they'll need to enable CRYPTO_SPECK_NEON to get acceptable performance. More details about our choice of Speck can be found in our patches that added Speck to the crypto API, and the follow-on discussion threads. We're planning a publication that explains the choice in more detail. But briefly, we can't use ChaCha20 as we previously proposed, since it would be insecure to use a stream cipher in this context, with potential IV reuse during writes on f2fs and/or on wear-leveling flash storage. We also evaluated many other lightweight and/or ARX-based block ciphers such as Chaskey-LTS, RC5, LEA, CHAM, Threefish, RC6, NOEKEON, SPARX, and XTEA. However, all had disadvantages vs. Speck, such as insufficient performance with NEON, much less published cryptanalysis, or an insufficient security level. Various design choices in Speck make it perform better with NEON than competing ciphers while still having a security margin similar to AES, and in the case of Speck128 also the same available security levels. Unfortunately, Speck does have some political baggage attached -- it's an NSA designed cipher, and was rejected from an ISO standard (though for context, as far as I know none of the above-mentioned alternatives are ISO standards either). Nevertheless, we believe it is a good solution to the problem from a technical perspective. Certain algorithms constructed from ChaCha or the ChaCha permutation, such as MEM (Masked Even-Mansour) or HPolyC, may also meet our performance requirements. However, these are new constructions that need more time to receive the cryptographic review and acceptance needed to be confident in their security. HPolyC hasn't been published yet, and we are concerned that MEM makes stronger assumptions about the underlying permutation than the ChaCha stream cipher does. In contrast, the XTS mode of operation is relatively well accepted, and Speck has over 70 cryptanalysis papers. Of course, these ChaCha-based algorithms can still be added later if they become ready. The best known attack on Speck128/256 is a differential cryptanalysis attack on 25 of 34 rounds with 2^253 time complexity and 2^125 chosen plaintexts, i.e. only marginally faster than brute force. There is no known attack on the full 34 rounds. Signed-off-by: Eric Biggers <ebiggers@google.com> Signed-off-by: Theodore Ts'o <tytso@mit.edu>

In most cases, there's no need to do so heavy fsync actually. So we introduce new mount option "fsync_mode={posix,strict}" to control the policy of fsync. "fsync_mode=posix" is set by default, and means that f2fs uses a light fsync, which follows POSIX semantics. And "fsync_mode=strict" means that it's a heavy fsync, which behaves in line with xfs, ext4 and btrfs, where generic/342 will pass, but the performance will regress.

However, issuing smaller discard may cost more lifetime but releasing less free space in flash device. Since f2fs has ability of separating hot/cold data and garbage collection, we can expect that small-sized invalid region would expand soon with OPU, deletion or garbage collection on valid datas, so it's better to delay or skip issuing smaller size discards, it could help to reduce overmuch consumption of IO bandwidth and lifetime of flash storage. This patch makes f2fs selectng 64K size as its default minimal granularity, and issue discard with the size which is not smaller than minimal granularity. Also it exposes discard granularity as sysfs entry for configuration in different scenario. Jaegeuk Kim: We must issue all the accumulated discard commands when fstrim is called. So, I've added pend_list_tag[] to indicate whether we should issue the commands or not. If tag sets P_ACTIVE or P_TRIM, we have to issue them. P_TRIM is set once at a time, given fstrim trigger. In addition, issue_discard_thread is calling too much due to the number of discard commands remaining in the pending list. I added a timer to control it likewise gc_thread.

We can't reclaim that during f2fs_evict_inode(). So, we need to count node blocks as well in order to match i_blocks with dquot's space. Note that, Chao wrote a patch to count inode->i_blocks without inode block. (f2fs: don't count inode block in in-memory inode.i_blocks) - in f2fs_remount, we need to make RW in prior to dquot_resume. - handle fault_injection case during f2fs_quota_off_umount - TODO: Project quota Signed-off-by: Chao Yu <yuchao0@huawei.com> Signed-off-by: Jaegeuk Kim <jaegeuk@kernel.org>

| | * | lib/vsprintf: Remove atomic-unsafe support for %pCrGeert Uytterhoeven2018-07-03

"%pCr" formats the current rate of a clock, and calls clk_get_rate(). The latter obtains a mutex, hence it must not be called from atomic context. Remove support for this rarely-used format, as vsprintf() (and e.g. printk()) must be callable from any context. Any remaining out-of-tree users will start seeing the clock's name printed instead of its rate.

The use of "exceeds" when the opposite of exceeds, falls below, was meant. 2. Properly speaking, a table can not exceed a threshold. It emphasizes the important point, which is that it is the userspace daemon's responsibility to check for low free space when a device is resumed, since it won't get a special event indicating low free space in that situation.
