brcmfmac: use local iftype avoiding use-after-free of virtual interface

2017-03-30T16:43:51Z

A use-after-free was found using KASAN. In brcmf_p2p_del_if() the virtual interface is removed using call to brcmf_remove_interface(). After that the virtual interface instance has been freed and should not be referenced. Solve this by storing the nl80211 iftype in local variable, which is used in a couple of places anyway.

sched/headers: Prepare to move signal wakeup & sigpending methods from into

2017-03-02T07:42:32Z

Fix up affected files that include this signal functionality via sched.h. Acked-by: Linus Torvalds Cc: Mike Galbraith Cc: Peter Zijlstra Cc: Thomas Gleixner Cc: linux-kernel@vger.kernel.org Signed-off-by: Ingo Molnar

sched/headers: Prepare for new header dependencies before moving code to

2017-03-02T07:42:29Z

We are going to split out of , which will have to be picked up from other headers and a couple of .c files. Create a trivial placeholder file that just maps to to make this patch obviously correct and bisectable. Include the new header in the files that are going to need it.

lib/vsprintf.c: remove %Z support

2017-02-28T02:43:47Z

Now that %z is standartised in C99 there is no reason to support %Z. Unlike %L it doesn't even make format strings smaller. Use BUILD_BUG_ON in a couple ATM drivers. In case anyone didn't notice lib/vsprintf.o is about half of SLUB which is in my opinion is quite an achievement. Hopefully this patch inspires someone else to trim vsprintf.c more.

brcmfmac: Use net_device_stats from struct net_device

2017-02-15T09:15:16Z

Instead of using a private copy of struct net_device_stats in struct brcm_if, use stats from struct net_device. Also remove the now unnecessary .ndo_get_stats function. Signed-off-by: Tobias Klauser Acked-by: Arend van Spriel Signed-off-by: Kalle Valo

brcmfmac: merge two remaining brcmf_err macros

2017-02-08T15:23:39Z

Now we always have __brcmf_err function we can do perfectly fine with just one macro. Signed-off-by: Rafał Miłecki Acked-by: Arend van Spriel Signed-off-by: Kalle Valo

brcmfmac: switch to C function (__brcmf_err) for printing errors

2017-02-08T15:23:39Z

This will allow extending code and using more detailed messages e.g. with the help of dev_err. Signed-off-by: Rafał Miłecki Acked-by: Arend van Spriel Signed-off-by: Kalle Valo

brcmfmac: merge two brcmf_err macros into one

This allows simplifying the code by adding a simple IS_ENABLED check for CONFIG_BRCMDB symbol. Signed-off-by: Rafał Miłecki Acked-by: Arend van Spriel Signed-off-by: Kalle Valo

brcmfmac: use wiphy_read_of_freq_limits to respect limits from DT

2017-02-07T07:57:07Z

This new helper reads extra frequency limits specified in DT and disables unavailable chanels. This is useful for devices (like home routers) with chipsets limited e.g. by board design. In order to respect info read from DT we simply need to check for IEEE80211_CHAN_DISABLED bit when constructing channel info. Signed-off-by: Rafał Miłecki Signed-off-by: Kalle Valo

brcmfmac: be more verbose when PSM's watchdog fires
