libertas: call into generic suspend code before turning off power

2018-10-10T12:01:50Z

When powering down a SDIO connected card during suspend, make sure to call into the generic lbs_suspend() function before pulling the plug. This will make sure the card is successfully deregistered from the system to avoid communication to the card starving out.

treewide: Replace more open-coded allocation size multiplications

2018-10-06T01:06:30Z

As done treewide earlier, this catches several more open-coded allocation size calculations that were added to the kernel during the merge window. This performs the following mechanical transformations using Coccinelle: kvmalloc(a * b, ...) -> kvmalloc_array(a, b, ...) kvzalloc(a * b, ...) -> kvcalloc(a, b, ...) devm_kzalloc(..., a * b, ...) -> devm_kcalloc(..., a, b, ...)

iwlwifi: 1000: set the TFD queue size

mac80211_hwsim: do not omit multicast announce of first added radio

2018-09-26T09:20:58Z

The allocation of hwsim radio identifiers uses a post-increment from 0, so the first radio has idx 0. This idx is explicitly excluded from multicast announcements ever since, but it is unclear why. Drop that idx check and announce the first radio as well. This makes userspace happy if it relies on these events. Signed-off-by: Martin Willi Signed-off-by: Johannes Berg

mac80211_hwsim: fix race in radio destruction from netlink notifier

2018-09-26T09:20:41Z

The asynchronous destruction from a work-queue of radios tagged with destroy-on-close may race with the owning namespace about to exit, resulting in potential use-after-free of that namespace. Instead of using a work-queue, move radios about to destroy to a temporary list, which can be worked on synchronously after releasing the lock. This should be safe to do from the netlink socket notifier, as the namespace is guaranteed to not get released. Signed-off-by: Martin Willi Signed-off-by: Johannes Berg

mac80211_hwsim: fix locking when iterating radios during ns exit

2018-09-26T09:20:13Z

The cleanup of radios during namespace exit has recently been reworked to directly delete a radio while temporarily releasing the spinlock, fixing a race condition between the work-queue execution and namespace exits. However, the temporary unlock allows unsafe modifications on the iterated list, resulting in a potential crash when continuing the iteration of additional radios. Move radios about to destroy to a temporary list, and clean that up after releasing the spinlock once iteration is complete.

b43: fix DMA error related regression with proprietary firmware

2018-09-20T11:58:39Z

In commit 66cffd6daab7 ("b43: fix transmit failure when VT is switched"), a condition is noted where the network controller needs to be reset. Note that this situation happens when running the open-source firmware (http://netweb.ing.unibs.it/~openfwwf/), plus a number of other special conditions. for a different card model, it is reported that this change breaks operation running the proprietary firmware (https://marc.info/?l=linux-wireless&m=153504546924558&w=2). Rather than reverting the previous patch, the code is tweaked to avoid the reset unless the open-source firmware is being used.
