====================
net: introduce IFF_NO_QUEUE as successor of zero tx_queue_len
This series adds a new private net_device flag indicating that a device may
(and probably should) be used without a queueing discipline attached to it.
This is already common practice for many virtual device types like e.g.
loopback, VLAN (802.1Q) or bridges (802.1D). The reason for this is that these
devices lack an underlying layer which could impose back pressure and therefore
making a TX queue necessary to not slow down senders.
Up to now, drivers being aware of the above applying to them set
dev->tx_queue_len to zero to indicate no qdisc should be attached to the
interface they drive and the kernel reacts upon this by assigning the noop
qdisc instead of the default pfifo_fast. This implicit agreement though leads
to an inconvenient situation once a user tries to attach a real qdisc to these
devices, as the formerly special tx_queue_len value becomes a regular one,
limiting the queue to zero packets and thus prevents any TX from happening. To
overcome this, practically all qdisc implementations intercept and sanitize the
malicious value.
With this series applied, drivers may signal the lack of need for a qdisc
without having to tamper with tx_queue_len, making fallbacks in qdiscs and
caveats in userspace unnecessary.
Upon upstream acceptance, this series will be followed up by a set of patches
converting device drivers, adding a warning so out-of-tree driver authors get
aware of this change and dropping all special handling of tx_queue_len in
net/sched/.

Chuck reports seeing cases where a GETATTR that happens to race
with an asynchronous WRITE is overriding the file size, despite
the attribute barrier being set by the writeback code.
The culprit turns out to be the check in nfs_ctime_need_update(),
which sees that the ctime is newer than the cached ctime, and
assumes that it is safe to override the attribute barrier.
This patch removes that override, and ensures that attribute
barriers are always respected.

Two issues were found on an IMX6 development board without an
enabled RTC device(resulting in the boot time and monotonic
time being initialized to 0).
Issue 1:exportfs -a generate:
"exportfs: /opt/nfs/arm does not support NFS export"
Issue 2:cat /proc/stat:
"btime 4294967236"
The same issues can be reproduced on x86 after running the
following code:
int main(void)
{
struct timeval val;
int ret;
val.tv_sec = 0;
val.tv_usec = 0;
ret = settimeofday(&val, NULL);
return 0;
}
Two issues are different symptoms of same problem:
The reason is a positive wall_to_monotonic pushes boot time back
to the time before Epoch, and getboottime will return negative
value.
In symptom 1:
negative boot time cause get_expiry() to overflow time_t
when input expire time is 2147483647, then cache_flush()
always clears entries just added in ip_map_parse.
In symptom 2:
show_stat() uses "unsigned long" to print negative btime
value returned by getboottime.
This patch fix the problem by prohibiting time from being set to a value which
would cause a negative boot time. As a result one can't set the CLOCK_REALTIME
time prior to (1970 + system uptime).

[jstultz: reworded commit message]
Signed-off-by: John Stultz <john.stultz@linaro.org>
timespec_trunc() avoids rounding if granularity <= nanoseconds-per-jiffie
(or TICK_NSEC). This optimization assumes that:
1. current_kernel_time().tv_nsec is already rounded to TICK_NSEC (i.e.
with HZ=1000 you'd get 1000000, 2000000, 3000000... but never 1000001).
This is no longer true (probably since hrtimers introduced in 2.6.16).
2. TICK_NSEC is evenly divisible by all possible granularities. This may
be true for HZ=100, 250, 1000, but obviously not for HZ=300 /
TICK_NSEC=3333333 (introduced in 2.6.20).
Thus, sub-second portions of in-core file times are not rounded to on-disk
granularity. I.e. file times may change when the inode is re-read from disk
or when the file system is remounted.
This affects all file systems with file time granularities > 1 ns and < 1s,
e.g. CEPH (1000 ns), UDF (1000 ns), CIFS (100 ns), NTFS (100 ns) and FUSE
(configurable from user mode via struct fuse_init_out.time_gran).
Steps to reproduce with e.g. UDF:
$ dd if=/dev/zero of=udfdisk count=10000 && mkudffs udfdisk
$ mkdir udf && mount udfdisk udf
$ touch udf/test && stat -c %y udf/test
2015-06-09 10:22:56.130006767 +0200
$ umount udf && mount udfdisk udf
$ stat -c %y udf/test
2015-06-09 10:22:56.130006000 +0200
Remounting truncates the mtime to 1 µs.
Fix the rounding in timespec_trunc() and update the documentation.
timespec_trunc() is exclusively used to calculate inode's [acm]time (mostly
via current_fs_time()), and always with super_block.s_time_gran as second
argument. So this can safely be changed without side effects.
Note: This does _not_ fix the issue for FAT's 2 second mtime resolution,
as super_block.s_time_gran isn't prepared to handle different ctime /
mtime / atime resolutions nor resolutions > 1 second.

I noticed for non-monotonic timers in timer_list, some of the
output looked a little confusing.
For example:
#1: <0000000000000000>, posix_timer_fn, S:01, hrtimer_start_range_ns, leap-a-day/2360
# expires at 1434412800000000000-1434412800000000000 nsecs [in 1434410725062375469 to 1434410725062375469 nsecs]
You'll note the relative time till the expiration "[in xxx to
yyy nsecs]" is incorrect. This is because its printing the delta
between CLOCK_MONOTONIC time to the CLOCK_REALTIME expiration.
This patch fixes this issue by adding the clock offset to the
"now" time which we use to calculate the delta.

USB-serial updates for v4.3-rc1
Here's a fix for a long-standing issue with the pl2303 divisor
calculations that affects some non-standard baudrates that were enabled
in v3.18.
Adding support for newer Edgeport devices and firmware required changes
to the io_ti driver and also exposed some issues with the driver's
current firmware handling.
Included is also a URL comment-typo fix.

There are some missing dependencies at the DT, as it looks for
an I2C bus named "ssc2", but this is not defined.
Probably, it misses some dependencies from some other tree.
For now, revert this patch, to avoid build breakages.
This reverts commit 5d8877b6ae.

Pull crypto fixes from Herbert Xu:
"This fixes the following issues:
- a regression caused by the conversion of IPsec ESP to the new AEAD
interface: ESN with authencesn no longer works because it relied on
the AD input SG list having a specific layout which is no longer
the case. In linux-next authencesn is fixed properly and no longer
assumes anything about the SG list format. While for this release
a minimal fix is applied to authencesn so that it works with the
new linear layout.
- fix memory corruption caused by bogus index in the caam hash code.
- fix powerpc nx SHA hashing which could cause module load failures
if module signature verification is enabled"
* git://git.kernel.org/pub/scm/linux/kernel/git/herbert/crypto-2.6:
crypto: caam - fix memory corruption in ahash_final_ctx
crypto: nx - respect sg limit bounds when building sg lists for SHA
crypto: authencesn - Fix breakage with new ESP code
WMI 10.4 uses the same command interface as QCA988X for addba/delba
debug wmi commands. Fill wmi_10_4_ops table with the functions used
for QCA988X for these commands.
With this change, the following debugfs entries can be used to
configure the aggregation mode and to send addba request,
addba response and delba respectively in manual aggregation mode
for QCA99X0 chip.

Header format of 10.4 firmware phyerr event is not alligned
with pre 10.4 firmware. Introduce new wmi handlers to parse
10.4 firmware specific phyerror event header.
With changes covered in this patch, radar detection works on
qca9x0 hw 2.0 which uses 10.4 firmware.

Existing phyerr event handlers directly uses phyerr header format
(ie, struct wmi_phyerr and struct wmi_phyerr_event) in the code
exactly on how firmware packs it. This is the problem in 10.4 fw
specific phyerr event handling where it uses different phyerror
header format. Before adding 10.4 specific handler, little bit of
refactor is done in existing phyerr handlers.
Two new abstracted structures (struct wmi_phyerr_ev_hdr_arg and
struct wmi_phyerr_ev_arg) are introduced to remove dependency of using
firmware specific header format in the code. So that firmware specific
phyerror handlers can populate values to abstracted structures and
the following code can use abstracted struct for further operation.
.pull_phyerr_hdr is added newly to pull common phyerr header info
like tsf, buf_len, number of phyerr packed. Existing .pull_phyerr
handler is changed and called to parse every sub phyerrs in the event.
Validated these refactoring on qca988x hw2.0 using fw 10.2.4 version.
