Hi Greg, Several peoples have reported the hung-task detector complains about an uninterruptible sleep in ccp driver with recent BIOS updates on Ryzen systems. During debug we found that recent BIOS updates have wrongly advertised that it supports SEV feature when it does not. We have made driver a bit more robust against this firmware bug. The patch is accepted in Linus tree for this. Due to some offset changes (and code restructure) I was not able to use upstream patch as-is. Doing a separate patch for 4.18, 4.17 and 4.16. Please let me know if you have any questions. ~ Brijesh -- 2.7.4

[PATCH 4.4] MIPS: VDSO: Match data page cache colouring when D$ aliases

by Paul Burton

[ Upstream commit 0f02cfbc3d9e413d450d8d0fd660077c23f67eff ] When a system suffers from dcache aliasing a user program may observe stale VDSO data from an aliased cache line. Notably this can break the expectation that clock_gettime(CLOCK_MONOTONIC, ...) is, as its name suggests, monotonic. In order to ensure that users observe updates to the VDSO data page as intended, align the user mappings of the VDSO data page such that their cache colouring matches that of the virtual address range which the kernel will use to update the data page - typically its unmapped address within kseg0. This ensures that we don't introduce aliasing cache lines for the VDSO data page, and therefore that userland will observe updates without requiring cache invalidation.

[PATCH 4.14-4.17 1/2] earlycon: Initialize port->uartclk based on clock-frequency property

by Rafał Miłecki

From: Michal Simek <michal.simek(a)xilinx.com> commit 814453adea7d081ad8917aa0f32d6a14165a3563 upstream. On DT based platforms when current-speed property is present baudrate is setup. Also port->uartclk is initialized to bogus BASE_BAUD * 16 value. Drivers like uartps/ns16550 contain logic when baudrate and uartclk is used for baudrate calculation. The patch is reading optional clock-frequency property to replace bogus BASE_BAUD * 16 calculation to have proper baudrate calculation. [-stable comment: commit 31cb9a8575ca ("earlycon: initialise baud field of earlycon device structure") has changed 8250_early.c behavior which now tries to setup UART speed. Ignoring clock-frequency results in wrong value of calculated divisor & malformed early console output.] Fixes: 31cb9a8575ca ("earlycon: initialise baud field of earlycon device structure") Signed-off-by: Michal Simek <michal.simek(a)xilinx.com> Signed-off-by: Greg Kroah-Hartman <gregkh(a)linuxfoundation.org> [rmilecki: add -stable comment and Fixes tag] Signed-off-by: Rafał Miłecki <rafal(a)milecki.pl> --- drivers/tty/serial/earlycon.c | 4 ++++ 1 file changed, 4 insertions(+) diff --git a/drivers/tty/serial/earlycon.c b/drivers/tty/serial/earlycon.c index ac667b47f199..05ba1875bb3e 100644 --- a/drivers/tty/serial/earlycon.c +++ b/drivers/tty/serial/earlycon.c @@ -289,6 +289,10 @@ int __init of_setup_earlycon(const struct earlycon_id *match, if (val) early_console_dev.baud = be32_to_cpu(*val); + val = of_get_flat_dt_prop(node, "clock-frequency", NULL); + if (val) + port->uartclk = be32_to_cpu(*val); + if (options) { early_console_dev.baud = simple_strtoul(options, NULL, 0); strlcpy(early_console_dev.options, options, -- 2.13.7

[stable v4.4.y 1/2] mei: me: allow runtime pm for platform with D0i3

by Tomas Winkler

commit cc365dcf0e56271bedf3de95f88922abe248e951 upstream. >From the pci power documentation: "The driver itself should not call pm_runtime_allow(), though. Instead, it should let user space or some platform-specific code do that (user space can do it via sysfs as stated above)..." However, the S0ix residency cannot be reached without MEI device getting into low power state. Hence, for mei devices that support D0i3, it's better to make runtime power management mandatory and not rely on the system integration such as udev rules. This policy cannot be applied globally as some older platforms were found to have broken power management. Cc: <stable(a)vger.kernel.org> # 4.4 Cc: Rafael J.

[PATCH] usb: typec: tcpm: Fix APDO PPS order checking to be based on voltage

by Adam Thomson

Current code mistakenly checks against max current to determine order but this should be max voltage. This commit fixes the issue so order is correctly determined, thus avoiding failure based on a higher voltage PPS APDO having a lower maximum current output, which is actually valid.

by gregkh＠linuxfoundation.org

As these devices only have one or two ports, fix this by making sure we only consider the seventh bit when determining the port number (and ignore bits 0xb0 which are typically set to 0x30).

[PATCH v2 3/6] drm/i915: Leave intel_conn->mst_port set, use mst_port_gone instead

by Lyude Paul

Currently we set intel_connector->mst_port to NULL to signify that the MST port has been removed from the system so that we can prevent further action on the port such as connector probes, mode probing, etc. However, we're going to need access to intel_connector->mst_port in order to fixup ->best_encoder() so that it can always return the correct encoder for an MST port to prevent legacy DPMS prop changes from failing. This should be safe, so instead keep intel_connector->mst_port always set and instead add intel_connector->mst_port_gone in order to signify whether or not the connector has disappeared from the system.

[PATCH AUTOSEL 4.9 01/34] binfmt_elf: Respect error return from `regset->active'

by Sasha Levin

From: "Maciej W. Rozycki" <macro(a)mips.com> [ Upstream commit 2f819db565e82e5f73cd42b39925098986693378 ] The regset API documented in <linux/regset.h> defines -ENODEV as the result of the `->active' handler to be used where the feature requested is not available on the hardware found. However code handling core file note generation in `fill_thread_core_info' interpretes any non-zero result from the `->active' handler as the regset requested being active. Consequently processing continues (and hopefully gracefully fails later on) rather than being abandoned right away for the regset requested. Fix the problem then by making the code proceed only if a positive result is returned from the `->active' handler. Signed-off-by: Maciej W.

[PATCH 3/4] Drivers: hv: kvp: Fix two "this statement may fall through" warnings

by kys＠linuxonhyperv.com

From: Dexuan Cui <decui(a)microsoft.com> We don't need to call process_ib_ipinfo() if message->kvp_hdr.operation is KVP_OP_GET_IP_INFO in kvp_send_key(), because here we just need to pass on the op code from the host to the userspace; when the userspace returns the info requested by the host, we pass the info on to the host in kvp_respond_to_host() -> process_ob_ipinfo(). BTW, the current buggy code actually doesn't cause any harm, because only message->kvp_hdr.operation is used by the userspace, in the case of KVP_OP_GET_IP_INFO. The patch also adds a missing "break;" in kvp_send_key(). BTW, the current buggy code actually doesn't cause any harm, because in the case of KVP_OP_SET, the unexpected fall-through corrupts message->body.kvp_set.data.key_size, but that is not really used: see the definition of struct hv_kvp_exchg_msg_value.

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);
