[PATCH] drm: avoid spurious EBUSY due to nonblocking atomic modesets

by Daniel Vetter

When doing an atomic modeset with ALLOW_MODESET drivers are allowed to pull in arbitrary other resources, including CRTCs (e.g. when reconfiguring global resources). But in nonblocking mode userspace has then no idea this happened, which can lead to spurious EBUSY calls, both: - when that other CRTC is currently busy doing a page_flip the ALLOW_MODESET commit can fail with an EBUSY - on the other CRTC a normal atomic flip can fail with EBUSY because of the additional commit inserted by the kernel without userspace's knowledge For blocking commits this isn't a problem, because everyone else will just block until all the CRTC are reconfigured. Only thing userspace can notice is the dropped frames without any reason for why frames got dropped. Consensus is that we need new uapi to handle this properly, but no one has any idea what exactly the new uapi should look like. As a stop-gap plug this problem by demoting nonblocking commits which might cause issues by including CRTCs not in the original request to blocking commits. v2: Add comments and a WARN_ON to enforce this only when allowed - we don't want to silently convert page flips into blocking plane updates just because the driver is buggy.

[PATCH 1/2] i2c: i801: Fix runtime PM

by Jarkko Nikula

Commit 9c8088c7988 ("i2c: i801: Don't restore config registers on runtime PM") nullified the runtime PM suspend/resume callback pointers while keeping the runtime PM enabled. This causes that device stays in D0 power state and sysfs /sys/bus/pci/devices/.../power/runtime_status shows "error" when runtime PM framework attempts to autosuspend the device. This is due PCI bus runtime PM which checks for driver runtime PM callbacks and returns with -ENOSYS if they are not set. Fix this by having a shared dummy runtime PM callback that returns with success.

[PATCH v2 1/3] fs/fuse, splice_write: Don't access pipe->buffers without pipe_lock()

by Andrey Ryabinin

fuse_dev_splice_write() reads pipe->buffers to determine the size of 'bufs' array before taking the pipe_lock(). This is not safe as another thread might change the 'pipe->buffers' between the allocation and taking the pipe_lock(). So we end up with too small 'bufs' array. Move the bufs allocations inside pipe_lock()/pipe_unlock() to fix this.

[Linux-stable-mirror] [PATCH] drbd: fix discard_zeroes_if_aligned regression

by Eric Wheeler

From: Eric Wheeler <git(a)linux.ewheeler.net> According to drbd.conf documentation, "To not break established and expected behaviour, and suddenly cause fstrim on thin-provisioned LVs to run out-of-space instead of freeing up space, the default value is yes." This behavior regressed in the REQ_OP_WRITE_ZEROES refactor near 45c21793 drbd: implement REQ_OP_WRITE_ZEROES 0dbed96 drbd: make intelligent use of blkdev_issue_zeroout which caused dm-thin backed DRBD volumes to zero blocks and run out of space instead of passing discard to the backing device as defined by the discard_zeroes_if_aligned option.

A GFP_ATOMIC allocation can fail, but init_crypt() in xts.c handles the allocation failure gracefully - it will fall back to preallocated buffer if the allocation fails. The crypto API maintainer says that the crypto API only needs to allocate memory when dealing with unaligned buffers and therefore turning CRYPTO_TFM_REQ_MAY_SLEEP off is safe (see this discussion: https://www.redhat.com/archives/dm-devel/2018-August/msg00195.html ) Cc: stable(a)vger.kernel.org Signed-off-by: Mikulas Patocka <mpatocka(a)redhat.com> Signed-off-by: Mike Snitzer <snitzer(a)redhat.com> diff --git a/drivers/md/dm-crypt.c b/drivers/md/dm-crypt.c index f266c81f396f..0481223b1deb 100644 --- a/drivers/md/dm-crypt.c +++ b/drivers/md/dm-crypt.c @@ -332,7 +332,7 @@ static int crypt_iv_essiv_init(struct crypt_config *cc) int err; desc->tfm = essiv->hash_tfm; - desc->flags = CRYPTO_TFM_REQ_MAY_SLEEP; + desc->flags = 0; err = crypto_shash_digest(desc, cc->key, cc->key_size, essiv->salt); shash_desc_zero(desc); @@ -606,7 +606,7 @@ static int crypt_iv_lmk_one(struct crypt_config *cc, u8 *iv, int i, r; desc->tfm = lmk->hash_tfm; - desc->flags = CRYPTO_TFM_REQ_MAY_SLEEP; + desc->flags = 0; r = crypto_shash_init(desc); if (r) @@ -768,7 +768,7 @@ static int crypt_iv_tcw_whitening(struct crypt_config *cc, /* calculate crc32 for every 32bit part and xor it */ desc->tfm = tcw->crc32_tfm; - desc->flags = CRYPTO_TFM_REQ_MAY_SLEEP; + desc->flags = 0; for (i = 0; i < 4; i++) { r = crypto_shash_init(desc); if (r) @@ -1251,7 +1251,7 @@ static void crypt_alloc_req_skcipher(struct crypt_config *cc, * requests if driver request queue is full. */ skcipher_request_set_callback(ctx->r.req, - CRYPTO_TFM_REQ_MAY_BACKLOG | CRYPTO_TFM_REQ_MAY_SLEEP, + CRYPTO_TFM_REQ_MAY_BACKLOG, kcryptd_async_done, dmreq_of_req(cc, ctx->r.req)); } @@ -1268,7 +1268,7 @@ static void crypt_alloc_req_aead(struct crypt_config *cc, * requests if driver request queue is full. */ aead_request_set_callback(ctx->r.req_aead, - CRYPTO_TFM_REQ_MAY_BACKLOG | CRYPTO_TFM_REQ_MAY_SLEEP, + CRYPTO_TFM_REQ_MAY_BACKLOG, kcryptd_async_done, dmreq_of_req(cc, ctx->r.req_aead)); } diff --git a/drivers/md/dm-integrity.c b/drivers/md/dm-integrity.c index 378878599466..89ccb64342de 100644 --- a/drivers/md/dm-integrity.c +++ b/drivers/md/dm-integrity.c @@ -532,7 +532,7 @@ static void section_mac(struct dm_integrity_c *ic, unsigned section, __u8 result unsigned j, size; desc->tfm = ic->journal_mac; - desc->flags = CRYPTO_TFM_REQ_MAY_SLEEP; + desc->flags = 0; r = crypto_shash_init(desc); if (unlikely(r)) { @@ -676,7 +676,7 @@ static void complete_journal_encrypt(struct crypto_async_request *req, int err) static bool do_crypt(bool encrypt, struct skcipher_request *req, struct journal_completion *comp) { int r; - skcipher_request_set_callback(req, CRYPTO_TFM_REQ_MAY_BACKLOG | CRYPTO_TFM_REQ_MAY_SLEEP, + skcipher_request_set_callback(req, CRYPTO_TFM_REQ_MAY_BACKLOG, complete_journal_encrypt, comp); if (likely(encrypt)) r = crypto_skcipher_encrypt(req);

[PATCH v3 1/2] nfit, mce: only handle uncorrectable machine checks

by Vishal Verma

The mce handler for 'nfit' devices is called for memory errors on a Non-Volatile DIMM, and adds the error location to a 'badblocks' list. This list is used by the various NVDIMM drivers to avoid consuming known poison locations during IO. The mce handler gets called for both corrected and uncorrectable errors. Until now, both kinds of errors have been added to the badblocks list. However, corrected memory errors indicate that the problem has already been fixed by hardware, and the resulting interrupt is merely a notification to Linux. As far as future accesses to that location are concerned, it is perfectly fine to use, and thus doesn't need to be included in the above badblocks list. Add a check in the nfit mce handler to filter out corrected mce events, and only process uncorrectable errors.

aacraid: Regression in 4.14.56 with *genirq/affinity: assign vectors to all possible CPUs*

by Paul Menzel

Dear Greg, Commit ef86f3a7 (genirq/affinity: assign vectors to all possible CPUs) added for Linux 4.14.56 causes the aacraid module to not detect the attached devices anymore on a Dell PowerEdge R720 with two six core 24x E5-2630 @ 2.30GHz. ``` $ dmesg | grep raid [ 0.269768] raid6: sse2x1 gen() 7179 MB/s [ 0.290069] raid6: sse2x1 xor() 5636 MB/s [ 0.311068] raid6: sse2x2 gen() 9160 MB/s [ 0.332076] raid6: sse2x2 xor() 6375 MB/s [ 0.353075] raid6: sse2x4 gen() 11164 MB/s [ 0.374064] raid6: sse2x4 xor() 7429 MB/s [ 0.379001] raid6: using algorithm sse2x4 gen() 11164 MB/s [ 0.386001] raid6: .... xor() 7429 MB/s, rmw enabled [ 0.391008] raid6: using ssse3x2 recovery algorithm [ 3.559682] megaraid cmm: 2.20.2.7 (Release Date: Sun Jul 16 00:01:03 EST 2006) [ 3.570061] megaraid: 2.20.5.1 (Release Date: Thu Nov 16 15:32:35 EST 2006) [ 10.725767] Adaptec aacraid driver 1.2.1[50834]-custom [ 10.731724] aacraid 0000:04:00.0: can't disable ASPM; OS doesn't have ASPM control [ 10.743295] aacraid: Comm Interface type3 enabled $ lspci -nn | grep Adaptec 04:00.0 Serial Attached SCSI controller [0107]: Adaptec Series 8 12G SAS/PCIe 3 [9005:028d] (rev 01) 42:00.0 Serial Attached SCSI controller [0107]: Adaptec Smart Storage PQI 12G SAS/PCIe 3 [9005:028f] (rev 01) ``` But, it still works with a Dell PowerEdge R715 with two eight core AMD Opteron 6136, the card below. ``` $ lspci -nn | grep Adaptec 22:00.0 Serial Attached SCSI controller [0107]: Adaptec Series 8 12G SAS/PCIe 3 [9005:028d] (rev 01) ``` Reverting the commit fixes the issue. commit ef86f3a72adb8a7931f67335560740a7ad696d1d Author: Christoph Hellwig <hch(a)lst.de> Date: Fri Jan 12 10:53:05 2018 +0800 genirq/affinity: assign vectors to all possible CPUs commit 84676c1f21e8ff54befe985f4f14dc1edc10046b upstream. Currently we assign managed interrupt vectors to all present CPUs. This works fine for systems were we only online/offline CPUs. But in case of systems that support physical CPU hotplug (or the virtualized version of it) this means the additional CPUs covered for in the ACPI tables or on the command line are not catered for. To fix this we'd either need to introduce new hotplug CPU states just for this case, or we can start assining vectors to possible but not present CPUs.

These asynchronous calls don't support vmalloc memory, but the buffer data can be allocated with vmalloc if dm-bufio is short of memory and uses a reserved buffer that was preallocated in dm_bufio_client_create(). Fix verity_hash_update() so that it deals with vmalloc'd memory correctly.
