Gabriel Krisman Bertazi	239aed5d2e	blk-cgroup: Pre-allocate tree node on blkg_conf_prep ... [ Upstream commit f255c19b3ab46d3cad3b1b2e1036f4c926cb1d0c ] Similarly to commit 457e490f2b ("blkcg: allocate struct blkcg_gq outside request queue spinlock"), blkg_create can also trigger occasional -ENOMEM failures at the radix insertion because any allocation inside blkg_create has to be non-blocking, making it more likely to fail. This causes trouble for userspace tools trying to configure io weights who need to deal with this condition. This patch reduces the occurrence of -ENOMEMs on this path by preloading the radix tree element on a GFP_KERNEL context, such that we guarantee the later non-blocking insertion won't fail. A similar solution exists in blkcg_init_queue for the same situation.

Greg Kroah-Hartman	8dda141d0b	Revert "block: ratelimit handle_bad_sector() message" ... This reverts commit f86b9bf622 which is commit f4ac712e4fe009635344b9af5d890fe25fcc8c0d upstream. Jari Ruusu writes: Above change "block: ratelimit handle_bad_sector() message" upstream commit f4ac712e4fe009635344b9af5d890fe25fcc8c0d in 4.19.154 kernel is not completely OK. Removing casts from arguments 4 and 5 produces these compile warnings: ... For 64 bit systems it is only compile time cosmetic warning. For 32 bit system + CONFIG_LBDAF=n it introduces bugs: output formats are "%llu" and passed parameters are 32 bits. That is not OK. Upstream kernels have hardcoded 64 bit sector_t. In older stable trees sector_t can be either 64 or 32 bit. In other words, backport of above patch needs to keep those original casts. And Tetsuo Handa writes: Indeed, commit f4ac712e4fe00963 ("block: ratelimit handle_bad_sector() message") depends on commit 72deb455b5ec619f ("block: remove CONFIG_LBDAF") which was merged into 5.2 kernel. So let's revert it.

Ming Lei	77064570e4	blk-mq: order adding requests to hctx->dispatch and checking SCHED_RESTART ... commit d7d8535f377e9ba87edbf7fbbd634ac942f3f54f upstream. SCHED_RESTART code path is relied to re-run queue for dispatch requests in hctx->dispatch. Meantime the SCHED_RSTART flag is checked when adding requests to hctx->dispatch. memory barriers have to be used for ordering the following two pair of OPs: 1) adding requests to hctx->dispatch and checking SCHED_RESTART in blk_mq_dispatch_rq_list() 2) clearing SCHED_RESTART and checking if there is request in hctx->dispatch in blk_mq_sched_restart(). Without the added memory barrier, either: 1) blk_mq_sched_restart() may miss requests added to hctx->dispatch meantime blk_mq_dispatch_rq_list() observes SCHED_RESTART, and not run queue in dispatch side or 2) blk_mq_dispatch_rq_list still sees SCHED_RESTART, and not run queue in dispatch side, meantime checking if there is request in hctx->dispatch from blk_mq_sched_restart() is missed. IO hang in ltp/fs_fill test is reported by kernel test robot: https://lkml.org/lkml/2020/7/26/77 Turns out it is caused by the above out-of-order OPs. And the IO hang can't be observed any more after applying this patch.

Eric Biggers	5da8f890a9	ANDROID: block: backport the ability to specify max_dun_bytes ... Backport a fix from the v7 inline crypto patchset which ensures that the block layer knows the number of DUN bytes the inline encryption hardware supports, so that hardware isn't used when it shouldn't be. (This unfortunately means introducing some increasing long argument lists; this was all already fixed up in later versions of the patchset.) To avoid breaking the KMI for drivers, don't add a dun_bytes argument to keyslot_manager_create() but rather allow drivers to call keyslot_manager_set_max_dun_bytes() to override the default. Also, don't add dun_bytes as a new field in 'struct blk_crypto_key' but rather pack it into the existing 'hash' field which is for block layer use.

Zhiqiang Liu	d999063be0	block, bfq: fix use-after-free in bfq_idle_slice_timer_body ... [ Upstream commit 2f95fa5c955d0a9987ffdc3a095e2f4e62c5f2a9 ] In bfq_idle_slice_timer func, bfqq = bfqd->in_service_queue is not in bfqd-lock critical section. The bfqq, which is not equal to NULL in bfq_idle_slice_timer, may be freed after passing to bfq_idle_slice_timer_body. So we will access the freed memory. In addition, considering the bfqq may be in race, we should firstly check whether bfqq is in service before doing something on it in bfq_idle_slice_timer_body func. If the bfqq in race is not in service, it means the bfqq has been expired through __bfq_bfqq_expire func, and wait_request flags has been cleared in __bfq_bfqd_reset_in_service func. So we do not need to re-clear the wait_request of bfqq which is not in service.

[ Upstream commit e74d93e96d721c4297f2a900ad0191890d2fc2b0 ] Field bdi->io_pages added in commit 9491ae4aad ("mm: don't cap request size based on read-ahead setting") removes unneeded split of read requests. Stacked drivers do not call blk_queue_max_hw_sectors(). Instead they set limits of their devices by blk_set_stacking_limits() + disk_stack_limits(). Field bio->io_pages stays zero until user set max_sectors_kb via sysfs. This patch updates io_pages after merging limits in disk_stack_limits().

Eric Biggers	8f078b1b3a	ANDROID: block: require drivers to declare supported crypto key type(s) ... We need a way to tell which type of keys the inline crypto hardware supports (standard, wrapped, or both), so that fallbacks can be used when needed (either blk-crypto-fallback, or fscrypt fs-layer crypto). We can't simply assume that keyslot_mgmt_ll_ops::derive_raw_secret == NULL means only standard keys are supported and that keyslot_mgmt_ll_ops::derive_raw_secret != NULL means that only wrapped keys are supported, because device-mapper devices always implement this method. Also, hardware might support both types of keys. Therefore, add a field keyslot_manager::features which contains a bitmask of flags which indicate the supported types of keys. Drivers will need to fill this in. This patch makes the UFS standard crypto code set BLK_CRYPTO_FEATURE_STANDARD_KEYS, but UFS variant drivers may need to set BLK_CRYPTO_FEATURE_WRAPPED_KEYS instead. Then, make keyslot_manager_crypto_mode_supported() take the key type into account.

Carlo Nonato	3cbfc33d43	block, bfq: fix overwrite of bfq_group pointer in bfq_find_set_group() ... [ Upstream commit 14afc59361976c0ba39e3a9589c3eaa43ebc7e1d ] The bfq_find_set_group() function takes as input a blkcg (which represents a cgroup) and retrieves the corresponding bfq_group, then it updates the bfq internal group hierarchy (see comments inside the function for why this is needed) and finally it returns the bfq_group. In the hierarchy update cycle, the pointer holding the correct bfq_group that has to be returned is mistakenly used to traverse the hierarchy bottom to top, meaning that in each iteration it gets overwritten with the parent of the current group. Since the update cycle stops at root's children (depth = 2), the overwrite becomes a problem only if the blkcg describes a cgroup at a hierarchy level deeper than that (depth > 2). In this case the root's child that happens to be also an ancestor of the correct bfq_group is returned. The main consequence is that processes contained in a cgroup at depth greater than 2 are wrongly placed in the group described above by BFQ. This commits fixes this problem by using a different bfq_group pointer in the update cycle in order to avoid the overwrite of the variable holding the original group reference.

Eric Biggers	582a710ae9	ANDROID: ufs, block: fix crypto power management and move into block layer ... The call to pm_runtime_get_sync() in ufshcd_program_key() can deadlock because it waits for the UFS controller to be resumed, but it can itself be reached while resuming the UFS controller via: - ufshcd_runtime_resume() - ufshcd_resume() - ufshcd_reset_and_restore() - ufshcd_host_reset_and_restore() - ufshcd_hba_enable() - ufshcd_hba_execute_hce() - ufshcd_hba_start() - ufshcd_crypto_enable() - keyslot_manager_reprogram_all_keys() - ufshcd_crypto_keyslot_program() - ufshcd_program_key() But pm_runtime_get_sync() *is* needed when evicting a key. Also, on pre-4.20 kernels it's needed when programming a keyslot for a bio since the block layer used to resume the device in a different place. Thus, it's hard for drivers to know what to do in .keyslot_program() and .keyslot_evict(). In old kernels it may even be impossible unless we were to pass more information down from the keyslot_manager. There's also another possible deadlock: keyslot programming and eviction take ksm->lock for write and then resume the device, which may result in ksm->lock being taken again via the above call stack. To fix this, we should resume the device before taking ksm->lock. Fix these problems by moving to a better design where the block layer (namely, the keyslot manager) handles runtime power management instead of drivers. This is analogous to the block layer's existing runtime power management support (blk-pm), which handles resuming devices when bios are submitted to them so that drivers don't need to handle it. Test: Tested on coral with: echo 5 > /sys/bus/platform/devices/1d84000.ufshc/rpm_lvl sleep 30 touch /data && sync # hangs before this fix Also verified via kvm-xfstests that blk-crypto-fallback continues to work both with and without CONFIG_PM=y.

Dave Chinner	f387897cf5	block: fix 32 bit overflow in __blkdev_issue_discard() ... commit 4800bf7bc8c725e955fcbc6191cc872f43f506d3 upstream. A discard cleanup merged into 4.20-rc2 causes fstests xfs/259 to fall into an endless loop in the discard code. The test is creating a device that is exactly 2^32 sectors in size to test mkfs boundary conditions around the 32 bit sector overflow region. mkfs issues a discard for the entire device size by default, and hence this throws a sector count of 2^32 into blkdev_issue_discard(). It takes the number of sectors to discard as a sector_t - a 64 bit value. The commit ba5d73851e71 ("block: cleanup __blkdev_issue_discard") takes this sector count and casts it to a 32 bit value before comapring it against the maximum allowed discard size the device has. This truncates away the upper 32 bits, and so if the lower 32 bits of the sector count is zero, it starts issuing discards of length 0. This causes the code to fall into an endless loop, issuing a zero length discards over and over again on the same sector.

Ming Lei	b77f9249e6	block: don't use bio->bi_vcnt to figure out segment number ... [ Upstream commit 1a67356e9a4829da2935dd338630a550c59c8489 ] It is wrong to use bio->bi_vcnt to figure out how many segments there are in the bio even though CLONED flag isn't set on this bio, because this bio may be splitted or advanced. So always use bio_segments() in blk_recount_segments(), and it shouldn't cause any performance loss now because the physical segment number is figured out in blk_queue_split() and BIO_SEG_VALID is set meantime since bdced438ac ("block: setup bi_phys_segments after splitting").

Eric Biggers	b32863f17f	ANDROID: dm: add dm-default-key target for metadata encryption ... Add a device-mapper target "dm-default-key" which assigns an encryption key to bios that aren't for the contents of an encrypted file. This ensures that all blocks on-disk will be encrypted with some key, without the performance hit of file contents being encrypted twice when fscrypt (File-Based Encryption) is used. It is only appropriate to use dm-default-key when key configuration is tightly controlled, like it is in Android, such that all fscrypt keys are at least as hard to compromise as the default key. Compared to the original version of dm-default-key, this has been modified to use the new vendor-independent inline encryption framework (which works even when no inline encryption hardware is present), the table syntax has been changed to match dm-crypt, and support for specifying Adiantum encryption has been added. These changes also mean that dm-default-key now always explicitly specifies the DUN (the IV). Also, to handle f2fs moving blocks of encrypted files around without the key, and to handle ext4 and f2fs filesystems mounted without '-o inlinecrypt', the mapping logic is no longer "set a key on the bio if it doesn't have one already", but rather "set a key on the bio unless the bio has the bi_skip_dm_default_key flag set". Filesystems set this flag on *all* bios for encrypted file contents, regardless of whether they are encrypting/decrypting the file using inline encryption or the traditional filesystem-layer encryption, or moving the raw data. For the bi_skip_dm_default_key flag, a new field in struct bio is used rather than a bit in bi_opf so that fscrypt_set_bio_crypt_ctx() can set the flag, minimizing the changes needed to filesystems. (bi_opf is usually overwritten after fscrypt_set_bio_crypt_ctx() is called.)

Eric Biggers	44e1174c18	ANDROID: dm: add support for passing through inline crypto support ... Update the device-mapper core to support exposing the inline crypto support of the underlying device(s) through the device-mapper device. This works by creating a "passthrough keyslot manager" for the dm device, which declares support for the set of (crypto_mode, data_unit_size) combos which all the underlying devices support. When a supported combo is used, the bio cloning code handles cloning the crypto context to the bios for all the underlying devices. When an unsupported combo is used, the blk-crypto fallback is used as usual. Crypto support on each underlying device is ignored unless the corresponding dm target opts into exposing it. This is needed because for inline crypto to semantically operate on the original bio, the data must not be transformed by the dm target. Thus, targets like dm-linear can expose crypto support of the underlying device, but targets like dm-crypt can't. (dm-crypt could use inline crypto itself, though.) When a key is evicted from the dm device, it is evicted from all underlying devices.

Satya Tangirala	e65d08ae68	ANDROID: block: Introduce passthrough keyslot manager ... The regular keyslot manager is designed for devices that have a small number of keyslots that need to be programmed with keys ahead of time, and bios that are sent to the device need to be tagged with a keyslot index. Some inline encryption hardware may not have any limitations on the number of keyslot, and may instead allow each bio to be tagged with a raw key, data unit number, etc. rather than a pre-programmed keyslot's index. These devices don't need any sort of keyslot management, and it's better for these devices not to have to allocate a regular keyslot manager with some fixed number of keyslots. These devices can instead set up a passthrough keyslot manager in their request queue, which require less resources than regular keyslot managers, as they simply do no-ops when trying to program keys into slots. Separately, the device mapper may map over devices that have inline encryption hardware, and it wants to pass the key along to the underlying hardware. While the DM layer can expose inline encryption capabilities by setting up a regular keyslot manager with some fixed number of keyslots in the dm device's request queue, this only wastes memory since the keys programmed into the dm device's request queue will never be used. Instead, it's better to set up a passthrough keyslot manager for dm devices.

Mikulas Patocka	a7f79052d1	block: fix an integer overflow in logical block size ... commit ad6bf88a6c19a39fb3b0045d78ea880325dfcf15 upstream. Logical block size has type unsigned short. That means that it can be at most 32768. However, there are architectures that can run with 64k pages (for example arm64) and on these architectures, it may be possible to create block devices with 64k block size. For exmaple (run this on an architecture with 64k pages): Mount will fail with this error because it tries to read the superblock using 2-sector access: device-mapper: writecache: I/O is not aligned, sector 2, size 1024, block size 65536 EXT4-fs (dm-0): unable to read superblock This patch changes the logical block size from unsigned short to unsigned int to avoid the overflow.

Barani Muthukumaran	a076eebee0	ANDROID: block: add KSM op to derive software secret from wrapped key ... Some inline encryption hardware supports protecting the keys in hardware and only exposing wrapped keys to software. To use this capability, userspace must provide a hardware-wrapped key rather than a raw key. However, users of inline encryption in the kernel won't necessarily use the user-specified key directly for inline encryption. E.g. with fscrypt with IV_INO_LBLK_64 policies, each user-provided key is used to derive a file contents encryption key, filenames encryption key, and key identifier. Since inline encryption can only be used with file contents, if the user were to provide a wrapped key there would (naively) be no way to encrypt filenames or derive the key identifier. This problem is solved by designing the hardware to internally use the unwrapped key as input to a KDF from which multiple cryptographically isolated keys can be derived, including both the inline crypto key (not exposed to software) and a secret that *is* exposed to software. Add a function to the keyslot manager to allow upper layers to request this software secret from a hardware-wrapped key.

Barani Muthukumaran	3e8c41805f	ANDROID: block: provide key size as input to inline crypto APIs ... Currently, blk-crypto uses the algorithm to determine the size of keys. However, some inline encryption hardware supports protecting keys from software by wrapping the storage keys with an ephemeral key. Since these wrapped keys are not of a fixed size, add the capability to provide the key size when initializing a blk_crypto_key, and update the keyslot manager to take size into account when comparing keys.

Satya Tangirala	b01c73ea71	BACKPORT: FROMLIST: Update Inline Encryption from v5 to v6 of patch series ... Changes v5 => v6: - Blk-crypto's kernel crypto API fallback is no longer restricted to 8-byte DUNs. It's also now separately configurable from blk-crypto, and can be disabled entirely, while still allowing the kernel to use inline encryption hardware. Further, struct bio_crypt_ctx takes up less space, and no longer contains the information needed by the crypto API fallback - the fallback allocates the required memory when necessary. - Blk-crypto now supports all file content encryption modes supported by fscrypt. - Fixed bio merging logic in blk-merge.c - Fscrypt now supports inline encryption with the direct key policy, since blk-crypto now has support for larger DUNs. - Keyslot manager now uses a hashtable to lookup which keyslot contains any particular key (thanks Eric!) - Fscrypt support for inline encryption now handles filesystems with multiple underlying block devices (thanks Eric!) - Numerous cleanups Bug: 137270441 Test: refer to I26376479ee38259b8c35732cb3a1d7e15f9b05a3 Change-Id: I13e2e327e0b4784b394cb1e7cf32a04856d95f01 Link: https://lore.kernel.org/linux-block/20191218145136.172774-1-satyat@google.com/ Signed-off-by: Satya Tangirala <satyat@google.com>	2020-01-13 07:11:38 -08:00

Ming Lei	42d72c9d28	block: fix single range discard merge ... commit 2a5cf35cd6c56b2924bce103413ad3381bdc31fa upstream. There are actually two kinds of discard merge: - one is the normal discard merge, just like normal read/write request, and call it single-range discard - another is the multi-range discard, queue_max_discard_segments(rq->q) > 1 For the former case, queue_max_discard_segments(rq->q) is 1, and we should handle this kind of discard merge like the normal read/write request. This patch fixes the following kernel panic issue[1], which is caused by not removing the single-range discard request from elevator queue. Guangwu has one raid discard test case, in which this issue is a bit easier to trigger, and I verified that this patch can fix the kernel panic issue in Guangwu's test case. [1] kernel panic log from Jens's report BUG: unable to handle kernel NULL pointer dereference at 0000000000000148 PGD 0 P4D 0.
