Eric W. Biderman and Michal Hocko reported various memory corruptions that we suspected to be related to a LIST head located on stack, that was manipulated after thread left function frame (and eventually exited, so its stack was freed and reused). Eric Dumazet suggested the problem was probably coming from commit 44345724 (net: factorize sync-rcu call in unregister_netdevice_many) This patch fixes __dev_close() and dev_close() to properly deinit their respective LIST_HEAD(single) before exiting.

When list debugging is enabled, we aim to readably show list corruption errors, and the basic list_add/list_del operations end up having extra debugging code in them to do some basic validation of the list entries. However, "list_del_init()" and "list_move[_tail]()" ended up avoiding the debug code due to how they were written. This fixes that. So the _next_ time we have list_move() problems with stale list entries, we'll hopefully have an easier time finding them.. Signed-off-by: NLinus Torvalds <torvalds@linux-foundation.org>

Uwe pointed out that my alarm based UIE emulation is not sufficient to replace the older timer/polling based UIE emulation on devices where there is no alarm irq. This causes rtc devices without alarms to return -EINVAL to UIE ioctls. The fix is to re-instate the old timer/polling method for devices without alarm irqs. This patch reverts the following commits: 042620a0 - Remove UIE emulation 1daeddd5 - Cleanup removed UIE emulation declaration b5cc8ca1 - Remove Kconfig symbol for UIE emulation The emulation mode will still need to be wired-in with a following patch before it will work.

If management firmware is present and the device is down, the firmware will assume control of the phy. If a phy access were allowed from the host, it will collide with firmware phy accesses, resulting in unpredictable behavior.

Without calling of netif_carrier_off at the end of the probe the operstate is unknown when the device is initially opened.

There is a double completion associated with error handling for RC QPs. The sequence is: - The do_rc_ack() routine fields an RNR nack and there are 0 rnr_retries configured on the QP. - qib_error_qp() stops the pending timer - qib_rc_send_complete() is called from sdma_complete() - qib_rc_send_complete() starts the timer because the msb of the psn just completed says an ack is needed. - a bunch of flushes occur as ipoib posts WQEs to an error'ed QP - rc_timeout() calls qib_restart_rc() - qib_restart_rc() calls qib_send_complete() with a IB_WC_RETRY_EXC_ERR on a wqe that has already been completed in the past The fix avoids starting the timer since another packet will never arrive.

Systems containing an 82599EB and running a backported driver from upstream were panicing on boot. It turns out hw->mac.ops.setup_sfp is only set for 82599, so one should check to be sure that pointer is set before continuing in ixgbe_sfp_config_module_task. I verified by inspection that the upstream driver has the same issue and also added a check before the call in ixgbe_sfp_link_config.

This reverts commit 75f1dc0d ("block: check bdev_read_only() from blkdev_get()"). That commit added stricter checking to make sure devices that were being used read-only were actually opened in that mode. It turns out that the change breaks a bunch of kernel code that opens block devices. Affected systems include dm, md, and the loop device. Because strict checking for read-only opens of block devices was not done before this, the code that opens the devices was opening them read-write even if they were being used read-only. Auditing all that code will take time, and new userspace packages for dm, mdadm, etc. will also be required.

Due to the default case handling the older chipsets, a bunch of the newer ones ended up having the wrong tiling regs used. This commit switches the default case to handle the newest chipsets. This also makes nv4e touch the "extra" tiling regs. "nv" doesn't touch them for C51 but traces of the NVIDIA binary driver show it being done there. I couldn't find NV41/NV45 traces to confirm the behaviour there, but an educated guess was taken at each of them. Signed-off-by: NBen Skeggs <bskeggs@redhat.com>
