2016-11-15rtnetlink: fix rtnl message size computation for XDPSabrina Dubroca
rtnl_xdp_size() only considers the size of the actual payload attribute, and misses the space taken by the attribute used for nesting (IFLA_XDP). Fixes: d1fdd9138682 ("rtnl: add option for setting link xdp prog") Signed-off-by: Sabrina Dubroca <sd@queasysnail.net> Reviewed-by: Brenden Blanco <bblanco@plumgrid.com> Signed-off-by: David S.

2016-11-15rtnetlink: fix rtnl_vfinfo_sizeSabrina Dubroca
The size reported by rtnl_vfinfo_size doesn't match the space used by rtnl_fill_vfinfo. rtnl_vfinfo_size currently doesn't account for the nest attributes used by statistics (added in commit 3b766cd83232), nor for struct ifla_vf_tx_rate (since commit ed616689a3d9, which added ifla_vf_rate to the dump without removing ifla_vf_tx_rate, but replaced ifla_vf_tx_rate with ifla_vf_rate in the size computation). Fixes: 3b766cd83232 ("net/core: Add reading VF statistics through the PF netdevice") Fixes: ed616689a3d9 ("net-next:v4: Add support to configure SR-IOV VF minimum and maximum Tx rate through ip tool") Signed-off-by: Sabrina Dubroca <sd@queasysnail.net> Signed-off-by: David S.

2016-11-15gro_cells: mark napi struct as not busy poll candidatesEric Dumazet
Rolf Neugebauer reported very long delays at netns dismantle. Eric W. Biederman was kind enough to look at this problem and noticed synchronize_net() occurring from netif_napi_del() that was added in linux-4.5 Busy polling makes no sense for tunnels NAPI. If busy poll is used for sessions over tunnels, the poller will need to poll the physical device queue anyway. netif_tx_napi_add() could be used here, but function name is misleading, and renaming it is not stable material, so set NAPI_STATE_NO_BUSY_POLL bit directly. This will avoid inserting gro_cells napi structures in napi_hash[] and avoid the problematic synchronize_net() (per possible cpu) that Rolf reported.

2016-11-15IB/rdmavt: rdmavt can handle non aligned page mapsDennis Dalessandro
The initial code for rdmavt carried with it a restriction that was a vestige from the qib driver, that to dma map a page it had to be less than a page size. This is not the case on modern hardware, both qib and hfi1 will be just fine with unaligned map requests. This fixes a 4.8 regression where by an IPoIB transfer of > PAGE_SIZE will hang because the dma map page call always fails. This was introduced after commit 5faba5469522 ("IB/ipoib: Report SG feature regardless of HW UD CSUM capability") added the capability to use SG by default. Rather than override this, the HW supports it, so allow SG.

After the module is finished, it calls back into the ftrace infrastructure to enable it.

2016-11-15kbuild: Steal gcc's pie from the very beginningBorislav Petkov
So Sebastian turned off the PIE for kernel builds but that was too late - Kbuild.include already uses KBUILD_CFLAGS and trying to disable gcc options with, say cc-disable-warning, fails: gcc -D__KERNEL__ -Wall -Wundef -Wstrict-prototypes -Wno-trigraphs ... -Wno-sign-compare -fno-asynchronous-unwind-tables -Wframe-address -c -x c /dev/null -o .31392.tmp /dev/null:1:0: error: code model kernel does not support PIC mode because that returns an error and we can't disable the warning. For example in this case: KBUILD_CFLAGS += $(call cc-disable-warning,frame-address,) which leads to gcc issuing all those warnings again. So let's turn off PIE/PIC at the earliest possible moment, when we declare KBUILD_CFLAGS so that cc-disable-warning picks it up too. Also, we need the $(call cc-option ...) because -fno-PIE is supported since gcc v3.4 and our lowest supported gcc version is 3.2 right now.

2016-11-15ARM: fix backtraceRussell King
Recent kernels have changed their behaviour to be more inconsistent when handling printk continuations. With todays kernels, the output looks sane on the console, but dmesg splits individual printk()s which do not have the KERN_CONT prefix into separate lines. Since the assembly code is not trivial to add the KERN_CONT, and we ideally want to avoid using KERN_CONT (as multiple printk()s can race between different threads), convert the assembly dumping the register values to C code, and have the C code build the output a line at a time before dumping to the console. This avoids the KERN_CONT issue, and also avoids situations where the output is intermixed with other console activity. Signed-off-by: Russell King <rmk+kernel@armlinux.org.uk>
