I'm announcing the release of the 4.4.129 kernel. All users of the 4.4 kernel series must upgrade. The updated 4.4.y git tree can be found at: git://git.kernel.org/pub/scm/linux/kernel/git/stable/linux-stable.git linux-4.4.y and can be browsed at the normal kernel.org git web browser: http://git.kernel.org/?p=linux/kernel/git/stable/linux-stable.git;a=summary thanks, greg k-h ------------ Makefile | 2 arch/arm/boot/dts/at91sam9g25.dtsi | 2 arch/arm/boot/dts/sama5d4.dtsi | 2 arch/mips/include/asm/uaccess.h | 11 -

Re: [GIT PULL] commits for Linux 4.14

by Sasha Levin

Ping on these? Also, at this point I seem to be building these trees faster than we deal with them (so for example, 4.15 has about 600 patches that didn't make it in before it went EOL). I also have about 600+ outstanding patches for 4.14 queued up. Would you be ok with making these batches bigger?

RE: [PATCH] [SCSI] mpt3sas: Fix secure erase premature termination (v4)

by Igor Rybak

Hi, We are running kernel 4.4.0-22 and the patch below does not seem to be present in the mpt3sas driver. Can you please confirm? As a reminder the patch was related to a Security Erase ATA command that requires a very long timeout like 100 minutes or more and the drive retains a busy status. And the driver should not try to send other commands or reset the drive. Thanks, Igor Rybak CTO MediaClone Inc 6900 Canby Ave Ste 107 Reseda, CA 91335 USA +1-818-654-6286 ________________________________________ From: Sreekanth Reddy [sreekanth.reddy(a)broadcom.com] Sent: Thursday, November 10, 2016 8:38 PM To: Andrey Grodzovsky Cc: PDL-MPT-FUSIONLINUX; Igor Rybak; Ezra Kohavi; linux-scsi(a)vger.kernel.org; Sathya Prakash; Chaitra P B; Suganath Prabu Subramani; Hannes Reinecke; stable(a)vger.kernel.org Subject: Re: [PATCH] [SCSI] mpt3sas: Fix secure erase premature termination (v4) On Thu, Nov 10, 2016 at 8:05 PM, Andrey Grodzovsky <andrey2805(a)gmail.com> wrote: > Problem: > This is a work around for a bug with LSI Fusion MPT SAS2 when > pefroming secure erase.

The first message is offloaded to hv_eject_device_work(), and the second is offloaded to pci_devices_present_work(). Both the paths can be running list_del(&hpdev->list_entry), causing general protection fault, because system_wq can run them concurrently. The patch eliminates the race condition. Since access to present/eject work items is serialized, we do not need the hbus->enum_sem anymore, so remove it.

[RHEL7.6 PATCH 22/37] Drivers: hv: vmbus: Fix a rescind issue

by Mohammed Gamal

The current rescind processing code will not correctly handle the case where the host immediately rescinds a channel that has been offerred. In this case, we could be blocked in the open call and since the channel is rescinded, the host will not respond and we could be blocked forever in the vmbus open call.i Fix this problem.

[Patch v2 1/6] cifs: smbd: Check for iov length on sending the last iov

by Long Li

From: Long Li <longli(a)microsoft.com> When sending the last iov that breaks into smaller buffers to fit the transfer size, it's necessary to check if this is the last iov. If this is the latest iov, stop and proceed to send pages.

[PATCH] mtd: spi-nor: Fix Cadence QSPI page fault kernel panic

by thor.thayer＠linux.intel.com

From: Thor Thayer <thor.thayer(a)linux.intel.com> The current Cadence QSPI driver caused a kernel panic when loading a Root Filesystem from QSPI. The problem was caused by reading more bytes than needed because the QSPI operated on 4 bytes at a time. <snip> [ 7.947754] spi_nor_read[1048]:from 0x037cad74, len 1 [bfe07fff] [ 7.956247] cqspi_read[910]:offset 0x58502516, buffer=bfe07fff [ 7.956247] [ 7.966046] Unable to handle kernel paging request at virtual address bfe08002 [ 7.973239] pgd = eebfc000 [ 7.975931] [bfe08002] *pgd=2fffb811, *pte=00000000, *ppte=00000000 </snip> Notice above how only 1 byte needed to be read but by reading 4 bytes into the end of a mapped page, an unrecoverable page fault occurred. This patch uses a temporary buffer to hold the 4 bytes read and then copies only the bytes required into the buffer. A min() function is used to limit the length to prevent buffer overflows. Request testing of this patch on other platforms. This was tested on the Intel Arria10 SoCFPGA DevKit. Fixes: 0cf1725676a97fc8 ("mtd: spi-nor: cqspi: Fix build on arches missing readsl/writesl") Signed-off-by: Thor Thayer <thor.thayer(a)linux.intel.com> Cc: <stable(a)vger.kernel.org> Reviewed-by: Marek Vasut <marek.vasut(a)gmail.com> --- v2 Changes to only write dangling bytes at end of transfer since previous patch may have multiple dangling byte transfers. Remove write patch since no errors reported and write timeout needs more investigation. v3 Add Fixes tag Cc-stable tag. --- drivers/mtd/spi-nor/cadence-quadspi.c | 19 +++++++++++++++++-- 1 file changed, 17 insertions(+), 2 deletions(-) diff --git a/drivers/mtd/spi-nor/cadence-quadspi.c b/drivers/mtd/spi-nor/cadence-quadspi.c index 2f3a4d4232b3..c3f7aaa5d18f 100644 --- a/drivers/mtd/spi-nor/cadence-quadspi.c +++ b/drivers/mtd/spi-nor/cadence-quadspi.c @@ -507,7 +507,9 @@ static int cqspi_indirect_read_execute(struct spi_nor *nor, u8 *rxbuf, void __iomem *reg_base = cqspi->iobase; void __iomem *ahb_base = cqspi->ahb_base; unsigned int remaining = n_rx; + unsigned int mod_bytes = n_rx % 4; unsigned int bytes_to_read = 0; + u8 *rxbuf_end = rxbuf + n_rx; int ret = 0; writel(from_addr, reg_base + CQSPI_REG_INDIRECTRDSTARTADDR); @@ -536,11 +538,24 @@ static int cqspi_indirect_read_execute(struct spi_nor *nor, u8 *rxbuf, } while (bytes_to_read != 0) { + unsigned int word_remain = round_down(remaining, 4); + bytes_to_read *= cqspi->fifo_width; bytes_to_read = bytes_to_read > remaining ? remaining : bytes_to_read; - ioread32_rep(ahb_base, rxbuf, - DIV_ROUND_UP(bytes_to_read, 4)); + bytes_to_read = round_down(bytes_to_read, 4); + /* Read 4 byte word chunks then single bytes */ + if (bytes_to_read) { + ioread32_rep(ahb_base, rxbuf, + (bytes_to_read / 4)); + } else if (!word_remain && mod_bytes) { + unsigned int temp = ioread32(ahb_base); + + bytes_to_read = mod_bytes; + memcpy(rxbuf, &temp, min((unsigned int) + (rxbuf_end - rxbuf), + bytes_to_read)); + } rxbuf += bytes_to_read; remaining -= bytes_to_read; bytes_to_read = cqspi_get_rd_sram_level(cqspi); -- 2.7.4
