brcmfmac: Make skb header writable before use

2017-05-14T12:06:00+00:00

commit 9cc4b7cb86cbcc6330a3faa8cd65268cd2d3c227 upstream. The driver was making changes to the skb_header without ensuring it was writable (i.e. uncloned). This patch also removes some boiler plate header size checking/adjustment code as that is also handled by the skb_cow_header function used to make header writable.

brcmfmac: Ensure pointer correctly set if skb data location changes

2017-05-14T12:06:00+00:00

commit 455a1eb4654c24560eb9dfc634f29cba3d87601e upstream. The incoming skb header may be resized if header space is insufficient, which might change the data adddress in the skb. Ensure that a cached pointer to that data is correctly set by moving assignment to after any possible changes.

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

2017-03-30T16:43:51+00:00

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

2017-03-02T07:42:32+00:00

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

2017-03-02T07:42:29+00:00

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

2017-02-28T02:43:47+00:00

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

2017-02-15T09:15:16+00:00

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

2017-02-08T15:23:39+00:00

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

2017-02-08T15:23:39+00:00

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
