Enable to specify local and remote prefix length thresholds for the
policy hash table via a netlink XFRM_MSG_NEWSPDINFO message.
prefix length thresholds are specified by XFRMA_SPD_IPV4_HTHRESH and
XFRMA_SPD_IPV6_HTHRESH optional attributes (struct xfrmu_spdhthresh).
example:
struct xfrmu_spdhthresh thresh4 = {
.lbits = 0;
.rbits = 24;
};
struct xfrmu_spdhthresh thresh6 = {
.lbits = 0;
.rbits = 56;
};
struct nlmsghdr *hdr;
struct nl_msg *msg;
msg = nlmsg_alloc();
hdr = nlmsg_put(msg, NL_AUTO_PORT, NL_AUTO_SEQ, XFRMA_SPD_IPV4_HTHRESH, sizeof(__u32), NLM_F_REQUEST);
nla_put(msg, XFRMA_SPD_IPV4_HTHRESH, sizeof(thresh4), &thresh4);
nla_put(msg, XFRMA_SPD_IPV6_HTHRESH, sizeof(thresh6), &thresh6);
nla_send_auto(sk, msg);
The numbers are the policy selector minimum prefix lengths to put a
policy in the hash table.
- lbits is the local threshold (source address for out policies,
destination address for in and fwd policies).
- rbits is the remote threshold (destination address for out
policies, source address for in and fwd policies).
The default values are:
XFRMA_SPD_IPV4_HTHRESH: 32 32
XFRMA_SPD_IPV6_HTHRESH: 128 128
Dynamic re-building of the SPD is performed when the thresholds values
are changed.
The current thresholds can be read via a XFRM_MSG_GETSPDINFO request:
the kernel replies to XFRM_MSG_GETSPDINFO requests by an
XFRM_MSG_NEWSPDINFO message, with both attributes
XFRMA_SPD_IPV4_HTHRESH and XFRMA_SPD_IPV6_HTHRESH.

The idea is an extension of the current policy hashing.
Today only non-prefixed policies are stored in a hash table. This
patch relaxes the constraints, and hashes policies whose prefix
lengths are greater or equal to a configurable threshold.
Each hash table (one per direction) maintains its own set of IPv4 and
IPv6 thresholds (dbits4, sbits4, dbits6, sbits6), by default (32, 32,
128, 128).
Example, if the output hash table is configured with values (16, 24,
56, 64):
ip xfrm policy add dir out src 10.22.0.0/20 dst 10.24.1.0/24 ... => hashed
ip xfrm policy add dir out src 10.22.0.0/16 dst 10.24.1.1/32 ... => hashed
ip xfrm policy add dir out src 10.22.0.0/16 dst 10.24.0.0/16 ... => unhashed
ip xfrm policy add dir out \
src 3ffe:304:124:2200::/60 dst 3ffe:304:124:2401::/64 ... => hashed
ip xfrm policy add dir out \
src 3ffe:304:124:2200::/56 dst 3ffe:304:124:2401::2/128 ... => hashed
ip xfrm policy add dir out \
src 3ffe:304:124:2200::/56 dst 3ffe:304:124:2400::/56 ... => unhashed
The high order bits of the addresses (up to the threshold) are used to
compute the hash key.

commit 39b2bbe3d7
"gpio: add flags argument to gpiod_get*() functions"
added a dynamic flags argument to all the GPIOD getter
functions, however this did not cover the stubs so
when people used gpiod stubs to compile out descriptor
code, compilation failed.
Solve this by:
- Also rename all the stub functions __gpiod_*
- Moving the vararg hack outside of #ifdef CONFIG_GPIOLIB
so these will always be available.

sk->sk_error_queue is dequeued in four locations. All share the
exact same logic. Deduplicate.
Also collapse the two critical sections for dequeue (at the top of
the recv handler) and signal (at the bottom).
This moves signal generation for the next packet forward, which should
be harmless.
It also changes the behavior if the recv handler exits early with an
error. Previously, a signal for follow-up packets on the errqueue
would then not be scheduled. The new behavior, to always signal, is
arguably a bug fix.
For rxrpc, the change causes the same function to be called repeatedly
for each queued packet (because the recv handler == sk_error_report).
It is likely that all packets will fail for the same reason (e.g.,
memory exhaustion).
This code runs without sk_lock held, so it is not safe to trust that
sk->sk_err is immutable inbetween releasing q->lock and the subsequent
test. Introduce int err just to avoid this potential race.

Add support for doing CHECKSUM_UNNECESSARY to CHECKSUM_COMPLETE
conversion in UDP tunneling path.
In the normal UDP path, we call skb_checksum_try_convert after locating
the UDP socket. The check is that checksum conversion is enabled for
the socket (new flag in UDP socket) and that checksum field is
non-zero.
In the UDP GRO path, we call skb_gro_checksum_try_convert after
checksum is validated and checksum field is non-zero. Since this is
already in GRO we assume that checksum conversion is always wanted.

For normal path, added skb_checksum_try_convert which is called
to attempt to convert CHECKSUM_UNNECESSARY to CHECKSUM_COMPLETE. The
primary condition to allow this is that ip_summed is CHECKSUM_NONE
and csum_valid is true, which will be the state after consuming
a CHECKSUM_UNNECESSARY.
For GRO path, added skb_gro_checksum_try_convert which is the GRO
analogue of skb_checksum_try_convert. The primary condition to allow
this is that NAPI_GRO_CB(skb)->csum_cnt == 0 and
NAPI_GRO_CB(skb)->csum_valid is set. This implies that we have consumed
all available CHECKSUM_UNNECESSARY checksums in the GRO path.

This flag indicates that an invalid checksum was detected in the
packet. __skb_mark_checksum_bad helper function was added to set this.
Checksums can be marked bad from a driver or the GRO path (the latter
is implemented in this patch). csum_bad is checked in
__skb_checksum_validate_complete (i.e. calling that when ip_summed ==
CHECKSUM_NONE).
csum_bad works in conjunction with ip_summed value. In the case that
ip_summed is CHECKSUM_NONE and csum_bad is set, this implies that the
first (or next) checksum encountered in the packet is bad. When
ip_summed is CHECKSUM_UNNECESSARY, the first checksum after the last
one validated is bad. For example, if ip_summed == CHECKSUM_UNNECESSARY,
csum_level == 1, and csum_bad is set-- then the third checksum in the
packet is bad. In the normal path, the packet will be dropped when
processing the protocol layer of the bad checksum:
__skb_decr_checksum_unnecessary called twice for the good checksums
changing ip_summed to CHECKSUM_NONE so that
__skb_checksum_validate_complete is called to validate the third
checksum and that will fail since csum_bad is set.

This commit adds some statictics in extent status tree shrinker. The
purpose to add these is that we want to collect more details when we
encounter a stall caused by extent status tree shrinker. Here we count
the following statictics:
stats:
the number of all objects on all extent status trees
the number of reclaimable objects on lru list
cache hits/misses
the last sorted interval
the number of inodes on lru list
average:
scan time for shrinking some objects
the number of shrunk objects
maximum:
the inode that has max nr. of objects on lru list
the maximum scan time for shrinking some objects
The output looks like below:
$ cat /proc/fs/ext4/sda1/es_shrinker_info
stats:
28228 objects
6341 reclaimable objects
5281/631 cache hits/misses
586 ms last sorted interval
250 inodes on lru list
average:
153 us scan time
128 shrunk objects
maximum:
255 inode (255 objects, 198 reclaimable)
125723 us max scan time
If the lru list has never been sorted, the following line will not be
printed:
586ms last sorted interval
If there is an empty lru list, the following lines also will not be
printed:
250 inodes on lru list
...
maximum:
255 inode (255 objects, 198 reclaimable)
0 us max scan time

Currently we suspend wakeup interrupts by lazy disabling them and
check later whether the interrupt has fired, but that's not sufficient
for suspend to idle as there is no way to check that once we
transitioned into the CPU idle state.
So we change the mechanism in the following way:
1) Leave the wakeup interrupts enabled across suspend
2) Add a check to irq_may_run() which is called at the beginning of
each flow handler whether the interrupt is an armed wakeup source.
This check is basically free as it just extends the existing check
for IRQD_IRQ_INPROGRESS. So no new conditional in the hot path.
If the IRQD_WAKEUP_ARMED flag is set, then the interrupt is
disabled, marked as pending/suspended and the pm core is notified
about the wakeup event.

Here's the weekly batch of fixes from arm-soc.
The delta is a largeish negative delta, due to revert of SMP support for Broadcom's

will make a new attempt for 3.18. I didn't see a need for a full revert of the whole

The rest is mostly:
* A handful of DT fixes for i.MX (Hummingboard/Cubox-i in particular)
* Some MTD/NAND fixes for OMAP
* Minor DT fixes for shmobile
* Warning fix for UP builds on vexpress/spc
There's also a couple of patches that wires up hwmod on TI's DRA7 SoC
so it can boot. Drivers and the rest had landed for 3.17, and it's small
and isolated so it made sense to pick up now even if it's not a bugfix.

Merge tag 'spi-v3.17-rc3-2' of git://git.kernel.org/pub/scm/linux/kernel/git/broonie/spi
Pull spi bugfixes from Mark Brown:
"A smattering of bug fixes for the SPI subsystem, all in driver code
which has seen active work recently and none of them with any great
global impact.
There's also a new ACPI ID for the pxa2xx driver which required no
code changes and the addition of kerneldoc for some structure fields
that were missing it and generating warnings during documentation
builds as a result"
