2021-03-07sysfs: Add sysfs_emit and sysfs_emit_at to format sysfs outputJoe Perches
commit 2efc459d06f1630001e3984854848a5647086232 upstream. Output defects can exist in sysfs content using sprintf and snprintf. sprintf does not know the PAGE_SIZE maximum of the temporary buffer used for outputting sysfs content and it's possible to overrun the PAGE_SIZE buffer length. Add a generic sysfs_emit function that knows that the size of the temporary buffer and ensures that no overrun is done. Add a generic sysfs_emit_at function that can be used in multiple call situations that also ensures that no overrun is done. Validate the output buffer argument to be page aligned. Validate the offset len argument to be within the PAGE_SIZE buf.

2020-09-12affs: fix basic permission bits to actually workMax Staudt
[ Upstream commit d3a84a8d0dde4e26bc084b36ffcbdc5932ac85e2 ] The basic permission bits (protection bits in AmigaOS) have been broken in Linux' AFFS - it would only set bits, but never delete them. Also, contrary to the documentation, the Archived bit was not handled. Let's fix this for good, and set the bits such that Linux and classic AmigaOS can coexist in the most peaceful manner. Also, update the documentation to represent the current state of things.

2019-06-13f2fs: Add option to limit required GC for checkpoint=disableDaniel Rosenberg
This extends the checkpoint option to allow checkpoint=disable:%u[%] This allows you to specify what how much of the disk you are willing to lose access to while mounting with checkpoint=disable. If the amount lost would be higher, the mount will return -EAGAIN. This can be given as a percent of total space, or in blocks. Currently, we need to run garbage collection until the amount of holes is smaller than the OVP space. With the new option, f2fs can mark space as unusable up front instead of requiring garbage collection until the number of holes is small enough.

2019-03-05ANDROID: overlayfs: override_creds=off option bypass creator_credMark Salyzyn
By default, all access to the upper, lower and work directories is the recorded mounter's MAC and DAC credentials. The incoming accesses are checked against the caller's credentials. If the principles of least privilege are applied, the mounter's credentials might not overlap the credentials of the caller's when accessing the overlayfs filesystem. For example, a file that a lower DAC privileged caller can execute, is MAC denied to the generally higher DAC privileged mounter, to prevent an attack vector. We add the option to turn off override_creds in the mount options; all subsequent operations after mount on the filesystem will be only the caller's credentials. The module boolean parameter and mount option override_creds is also added as a presence check for this "feature", existence of /sys/module/overlay/parameters/override_creds. It was not always this way. Circa 4.6 there was no recorded mounter's credentials, instead privileged access to upper or work directories were temporarily increased to perform the operations. The MAC (selinux) policies were caller's in all cases. override_creds=off partially returns us to this older access model minus the insecure temporary credential increases. This is to permit use in a system with non-overlapping security models for each executable including the agent that mounts the overlayfs filesystem. In Android this is the case since init, which performs the mount operations, has a minimal MAC set of privileges to reduce any attack surface, and services that use the content have a different set of MAC privileges (eg: read, for vendor labelled configuration, execute for vendor libraries and modules). The caveats are not a problem in the Android usage model, however they should be fixed for completeness and for general use in time.

2019-01-26mm, proc: be more verbose about unstable VMA flags in /proc/<pid>/smapsMichal Hocko
[ Upstream commit 7550c6079846a24f30d15ac75a941c8515dbedfb ] Patch series "THP eligibility reporting via proc". This series of three patches aims at making THP eligibility reporting much more robust and long term sustainable. The trigger for the change is a regression report [2] and the long follow up discussion. In short the specific application didn't have good API to query whether a particular mapping can be backed by THP so it has used VMA flags to workaround that. These flags represent a deep internal state of VMAs and as such they should be used by userspace with a great deal of caution. A similar has happened for [3] when users complained that VM_MIXEDMAP is no longer set on DAX mappings. Again a lack of a proper API led to an abuse. The first patch in the series tries to emphasise that that the semantic of flags might change and any application consuming those should be really careful. The remaining two patches provide a more suitable interface to address [2] and provide a consistent API to query the THP status both for each VMA and process wide as well. [1] http://lkml.kernel.org/r/20181120103515.25280-1-mhocko@kernel.org [2] http://lkml.kernel.org/r/http://lkml.kernel.org/r/alpine.DEB.2.21.1809241054050.224429@chino.kir.corp.google.com [3] http://lkml.kernel.org/r/20181002100531.GC4135@quack2.suse.cz This patch (of 3): Even though vma flags exported via /proc/<pid>/smaps are explicitly documented to be not guaranteed for future compatibility the warning doesn't go far enough because it doesn't mention semantic changes to those flags. And they are important as well because these flags are a deep implementation internal to the MM code and the semantic might change at any time. Let's consider two recent examples: http://lkml.kernel.org/r/20181002100531.GC4135@quack2.suse.cz : commit e1fb4a086495 "dax: remove VM_MIXEDMAP for fsdax and device dax" has : removed VM_MIXEDMAP flag from DAX VMAs. Now our testing shows that in the : mean time certain customer of ours started poking into /proc/<pid>/smaps : and looks at VMA flags there and if VM_MIXEDMAP is missing among the VMA : flags, the application just fails to start complaining that DAX support is : missing in the kernel. http://lkml.kernel.org/r/alpine.DEB.2.21.1809241054050.224429@chino.kir.corp.google.com : Commit 1860033237d4 ("mm: make PR_SET_THP_DISABLE immediately active") : introduced a regression in that userspace cannot always determine the set : of vmas where thp is ineligible. : Userspace relies on the "nh" flag being emitted as part of /proc/pid/smaps : to determine if a vma is eligible to be backed by hugepages. : Previous to this commit, prctl(PR_SET_THP_DISABLE, 1) would cause thp to : be disabled and emit "nh" as a flag for the corresponding vmas as part of : /proc/pid/smaps. After the commit, thp is disabled by means of an mm : flag and "nh" is not emitted. : This causes smaps parsing libraries to assume a vma is eligible for thp : and ends up puzzling the user on why its memory is not backed by thp. In both cases userspace was relying on a semantic of a specific VMA flag. The primary reason why that happened is a lack of a proper interface. While this has been worked on and it will be fixed properly, it seems that our wording could see some refinement and be more vocal about semantic aspect of these flags as well.

2018-10-29f2fs: checkpoint disablingDaniel Rosenberg
Note that, it requires "f2fs: return correct errno in f2fs_gc". This adds a lightweight non-persistent snapshotting scheme to f2fs. To use, mount with the option checkpoint=disable, and to return to normal operation, remount with checkpoint=enable. If the filesystem is shut down before remounting with checkpoint=enable, it will revert back to its apparent state when it was first mounted with checkpoint=disable. This is useful for situations where you wish to be able to roll back the state of the disk in case of some critical failure.

2018-09-18f2fs: support fault_type mount optionChao Yu
Previously, once fault injection is on, by default, all kind of faults will be injected to f2fs, if we want to trigger single or specified combined type during the test, we need to configure sysfs entry, it will be a little inconvenient to integrate sysfs configuring into testsuit, such as xfstest. So this patch introduces a new mount option 'fault_type' to assist old option 'fault_injection', with these two mount options, we can specify any fault rate/type at mount-time.

2018-06-28fscrypt: add Speck128/256 supportEric Biggers
fscrypt currently only supports AES encryption. 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>

2018-04-12f2fs/fscrypt: updates to v4.17-rc1Jaegeuk Kim
Pull f2fs update from Jaegeuk Kim: "In this round, we've mainly focused on performance tuning and critical bug fixes occurred in low-end devices. Sheng Yong introduced lost_found feature to keep missing files during recovery instead of thrashing them. We're preparing coming fsverity implementation. And, we've got more features to communicate with users for better performance. In low-end devices, some memory-related issues were fixed, and subtle race condtions and corner cases were addressed as well. Enhancements: - large nat bitmaps for more free node ids - add three block allocation policies to pass down write hints given by user - expose extension list to user and introduce hot file extension - tune small devices seamlessly for low-end devices - set readdir_ra by default - give more resources under gc_urgent mode regarding to discard and cleaning - introduce fsync_mode to enforce posix or not - nowait aio support - add lost_found feature to keep dangling inodes - reserve bits for future fsverity feature - add test_dummy_encryption for FBE Bug fixes: - don't use highmem for dentry pages - align memory boundary for bitops - truncate preallocated blocks in write errors - guarantee i_times on fsync call - clear CP_TRIMMED_FLAG correctly - prevent node chain loop during recovery - avoid data race between atomic write and background cleaning - avoid unnecessary selinux violation warnings on resgid option - GFP_NOFS to avoid deadlock in quota and read paths - fix f2fs_skip_inode_update to allow i_size recovery In addition to the above, there are several minor bug fixes and clean-ups" Cherry-pick from origin/upstream-f2fs-stable-linux-4.4.y: 42bf67fc543b f2fs: remain written times to update inode during fsync 6cb5aa02bfbd f2fs: make assignment of t->dentry_bitmap more readable a8d07f1f9c62 f2fs: truncate preallocated blocks in error case 86444d600692 f2fs: fix a wrong condition in f2fs_skip_inode_update db2188a68704 f2fs: reserve bits for fs-verity ee2e74b3f00e f2fs: Add a segment type check in inplace write 0192e0a4502f f2fs: no need to initialize zero value for GFP_F2FS_ZERO 49338842e9b2 f2fs: don't track new nat entry in nat set d6a69d5e6568 f2fs: clean up with F2FS_BLK_ALIGN 2c8834a7a2c9 f2fs: check blkaddr more accuratly before issue a bio 6ab573a9d96f f2fs: Set GF_NOFS in read_cache_page_gfp while doing f2fs_quota_read 7419dcb8be02 f2fs: introduce a new mount option test_dummy_encryption 9321e22c038c f2fs: introduce F2FS_FEATURE_LOST_FOUND feature 8a5719615847 f2fs: release locks before return in f2fs_ioc_gc_range() 739ace131cdf f2fs: align memory boundary for bitops 4c55abe4f8d2 f2fs: remove unneeded set_cold_node() 30654507e0a2 f2fs: add nowait aio support d909e9410634 f2fs: wrap all options with f2fs_sb_info.mount_opt 5738be52b3e8 f2fs: Don't overwrite all types of node to keep node chain 0bdeb167c843 f2fs: introduce mount option for fsync mode 6bc490f0eedc f2fs: fix to restore old mount option in ->remount_fs 0c9c3e034410 f2fs: wrap sb_rdonly with f2fs_readonly 6c6611223a79 f2fs: avoid selinux denial on CAP_SYS_RESOURCE 076a6f32fe5d f2fs: support hot file extension 58edcdbca67a f2fs: fix to avoid race in between atomic write and background GC 1e0aeb0af9ed f2fs: do gc in greedy mode for whole range if gc_urgent mode is set 10b2d001d6ac f2fs: issue discard aggressively in the gc_urgent mode a5052f32b940 f2fs: set readdir_ra by default 1aa536a624cc f2fs: add auto tuning for small devices 0ffdffc8f106 f2fs: add mount option for segment allocation policy b79829891249 f2fs: don't stop GC if GC is contended 766d2321697f f2fs: expose extension_list sysfs entry 98b329de5026 f2fs: fix to set KEEP_SIZE bit in f2fs_zero_range 4d409fa3346b f2fs: introduce sb_lock to make encrypt pwsalt update exclusive 1f6bac14c100 f2fs: remove redundant initialization of pointer 'p' 946aefc7545d f2fs: flush cp pack except cp pack 2 page at first e5081a52ac09 f2fs: clean up f2fs_sb_has_xxx functions a292477154b5 f2fs: remove redundant check of page type when submit bio 190e64a819df f2fs: fix to handle looped node chain during recovery 889d98087652 f2fs: handle quota for orphan inodes 92b12bb1a23e f2fs: support passing down write hints to block layer with F2FS policy 22fa74c2b097 f2fs: support passing down write hints given by users to block layer 180900373ec1 f2fs: fix to clear CP_TRIMMED_FLAG 0671fae134bb f2fs: support large nat bitmap eceb943d5d59 f2fs: fix to check extent cache in f2fs_drop_extent_tree 2e2a339c9853 f2fs: restrict inline_xattr_size configuration 41dda1164137 f2fs: fix heap mode to reset it back 39575737bb62 f2fs: fix potential corruption in area before F2FS_SUPER_OFFSET 7e0e7995ee97 fscrypt: fix build with pre-4.6 gcc versions 31d3279a4fca fscrypt: fix up fscrypt_fname_encrypted_size() for internal use 82bec888567b fscrypt: define fscrypt_fname_alloc_buffer() to be for presented names 168a90782888 fscrypt: calculate NUL-padding length in one place only 042ae9f4cfbf fscrypt: move fscrypt_symlink_data to fscrypt_private.h f9550c24c20e fscrypt: remove fscrypt_fname_usr_to_disk() 7ac4756a2474 f2fs: switch to fscrypt_get_symlink() 6b76f58e24bd f2fs: switch to fscrypt ->symlink() helper functions fd457d2c4e04 fscrypt: new helper function -

2018-04-08f2fs: introduce a new mount option test_dummy_encryptionSheng Yong
This patch introduces a new mount option `test_dummy_encryption' to allow fscrypt to create a fake fscrypt context. This is used by xfstests. Signed-off-by: Sheng Yong <shengyong1@huawei.com> Reviewed-by: Chao Yu <yuchao0@huawei.com> Signed-off-by: Jaegeuk Kim <jaegeuk@kernel.org>
2018-04-08f2fs: introduce mount option for fsync modeJunling Zheng
Commit "0a007b97aad6"(f2fs: recover directory operations by fsync) fixed xfstest generic/342 case, but it also increased the written data and caused the performance degradation. 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.

2018-04-08f2fs: add mount option for segment allocation policyJaegeuk Kim
This patch adds an mount option, "alloc_mode=%s" having two options, "default" and "reuse". In "alloc_mode=reuse" case, f2fs starts to allocate segments from 0'th segment all the time to reassign segments. It'd be useful for small-sized eMMC parts.

2018-04-08fs/proc: Stop trying to report thread stacksAndy Lutomirski
commit b18cb64ead400c01bf1580eeba330ace51f8087d upstream. This reverts more of: b76437579d13 ("procfs: mark thread stack correctly in proc/<pid>/maps") ... which was partially reverted by: 65376df58217 ("proc: revert /proc/<pid>/maps [stack:TID] annotation") Originally, /proc/PID/task/TID/maps was the same as /proc/TID/maps. In current kernels, /proc/PID/maps (or /proc/TID/maps even for threads) shows "[stack]" for VMAs in the mm's stack address range. In contrast, /proc/PID/task/TID/maps uses KSTK_ESP to guess the target thread's stack's VMA. This is racy, probably returns garbage and, on arches with CONFIG_TASK_INFO_IN_THREAD=y, is also crash-prone: KSTK_ESP is not safe to use on tasks that aren't known to be running ordinary process-context kernel code. This patch removes the difference and just shows "[stack]" for VMAs in the mm's stack range. This is IMO much more sensible -- the actual "stack" address really is treated specially by the VM code, and the current thread stack isn't even well-defined for programs that frequently switch stacks on their own.
