[PATCH RESEND stable 5.10] mtd: rawnand: gpmi: Set WAIT_FOR_READY timeout based on program/erase times

by Tim Harvey

From: Sascha Hauer <s.hauer(a)pengutronix.de> 06781a5026350 Fixes the calculation of the DEVICE_BUSY_TIMEOUT register value from busy_timeout_cycles. busy_timeout_cycles is calculated wrong though: It is calculated based on the maximum page read time, but the timeout is also used for page write and block erase operations which require orders of magnitude bigger timeouts. Fix this by calculating busy_timeout_cycles from the maximum of tBERS_max and tPROG_max. This is for now the easiest and most obvious way to fix the driver. There's room for improvements though: The NAND_OP_WAITRDY_INSTR tells us the desired timeout for the current operation, so we could program the timeout dynamically for each operation instead of setting a fixed timeout. Also we could wire up the interrupt handler to actually detect and forward timeouts occurred when waiting for the chip being ready. As a sidenote I verified that the change in 06781a5026350 is really correct. I wired up the interrupt handler in my tree and measured the time between starting the operation and the timeout interrupt handler coming in. The time increases 41us with each step in the timeout register which corresponds to 4096 clock cycles with the 99MHz clock that I have.

[PATCH stable 5.4] cgroup-v1: add disabled controller check in cgroup1_parse_param()

by Luiz Capitulino

From: Chen Zhou <chenzhou10(a)huawei.com> Commit 61e960b07b637f0295308ad91268501d744c21b5 upstream. [ This backport uses invalf() instead of invalfc() since the latter is only available starting with v5.6 ] When mounting a cgroup hierarchy with disabled controller in cgroup v1, all available controllers will be attached. For example, boot with cgroup_no_v1=cpu or cgroup_disable=cpu, and then mount with "mount -t cgroup -ocpu cpu /sys/fs/cgroup/cpu", then all enabled controllers will be attached except cpu. Fix this by adding disabled controller check in cgroup1_parse_param(). If the specified controller is disabled, just return error with information "Disabled controller xx" rather than attaching all the other enabled controllers.

Wong (2): xfs: clear XFS_DQ_FREEING if we can't lock the dquot buffer to flush xfs: force the log after remapping a synchronous-writes file fs/xfs/xfs_bmap_util.c | 2 +- fs/xfs/xfs_file.c | 17 ++++++++++++++++- fs/xfs/xfs_qm.c | 1 + 3 files changed, 18 insertions(+), 2 deletions(-) -- 2.35.1

[PATCH 4.14 00/34] Retbleed & PBRSB Mitigations

by Suraj Jitindar Singh

This backport adds support for Retbleed and PBRSB mitigations for Intel parts. Some AMD parts are added to simplify context however support for IBPB or UNRET is not included in this series. The reporting of whether a cpu is affected should be correct however. Most patches applied cleanly or required only context changes, the major difference between this series and upstream is the fact that the kvm entry path is in inline asm in the 4.14 tree and so this had to be accommodated in patches: - x86/speculation: Fill RSB on vmexit for IBRS - x86/speculation: Add RSB VM Exit protections This series is unsurprisingly very similar to that for the 5.4 backport [1]. Boot tested on a variety of Intel and AMD systems. Tested correct reporting of vulnerabilities and mitigation selection on Skylake, Cascade Lake, Ice Lake and Zen3 parts.

The newly added check for online devices incorrectly assumes that an I/O-subchannel's drvdata points to a struct io_subchannel_private. For devices that are bound to a non-default I/O subchannel driver, such as the vfio_ccw driver, this results in an out-of-bounds read access during each scan. Fix this by changing the scan logic to rely on a driver-independent online indication. For this we can use struct subchannel->config.ena, which is the driver's requested subchannel-enabled state. Since I/Os can only be started on enabled subchannels, this matches the intent of the original optimization of not scanning devices where I/O might be running.
