USB: f_fs: Fix disconnect check during ongoing IO
F_FS function driver allocated ffs_eps and updates ffs_ep->ep
to corresponding usb_ep during func->bind and never clears it.
On bind it also saves ffs_ep context in epfile->ep.
During func->disable, it clears only ffs_ep context in epfile->ep
and on func->unbind it frees ffs_eps memory.
ffs_epfile_io routine currently relies on ffs_ep->ep (which is
never cleared and ffs_ep could be freed on unbind) to detect any
disconnect during active IO. This can result in various issues e.g.
use after free use of ffs_ep if unbind finished before epfile_io
could resume or "stop adbd" trying to dequeue a freed USB request
when epfile_io could execute only after F_FS got disabled as
'if (ep->ep)' check would be TRUE.

USB: f_fs: Fail stale read IOs after disconnect
After a USB disconnect, endpoints for adb are disabled.
After this no IO is allowed on the endpoints.
Since, adbd is not aware of this disconnect, it may
still perform read/writes IO. For adb writes, IOs are
failed, but for adb reads kernel waits untill endpoints
are enabled.
When a USB disconnect and adb read still queued
a buffer to kernel, ffs_epfile_io simply waits for
endpoint to be enabled. A next connect happens
and endpoints are enabled after set_alt, the adb
read stale buffer from previous session continues
and queues to endpoint.
All this time, adb did not close the epfile because
it did not get return status on the IOs which it
queued. This is an issue, because a new session
is not established and both userspace and kernel
goes out of sync.
To fix this issue, when endpoints are disbled
set epfile error. This epfile error is only cleared
in epfile open. This will ensure that after a USB
disconnect and connect, new session is established.
Also, return ENODEV if endpoints not enabled rather
than EINTR as EINTR case, and simply retries the
request. Incase usb_ep_queue failed, return -EIO

UBSAN: run-time undefined behavior sanity checker
UBSAN uses compile-time instrumentation to catch undefined behavior
(UB). Compiler inserts code that perform certain kinds of checks before
operations that could cause UB. If check fails (i.e. UB detected)
__ubsan_handle_* function called to print error message.
So the most of the work is done by compiler. This patch just implements
ubsan handlers printing errors.
GCC has this capability since 4.9.x [1] (see -fsanitize=undefined
option and its suboptions).
However GCC 5.x has more checkers implemented [2].
Article [3] has a bit more details about UBSAN in the GCC.

kernel: printk: specify alignment for struct printk_log
On architectures that have support for efficient unaligned access struct
printk_log has 4-byte alignment. Specify alignment attribute in type

The whole point of this patch is to fix deadlock which happening when
UBSAN detects unaligned access in printk() thus UBSAN recursively calls
printk() with logbuf_lock held by top printk() call.

netfilter: xtables: hardidletimer target implementation
This patch implements a hardidletimer Xtables target that can be used to
identify when interfaces have been idle for a certain period of time.
Timers are identified by labels and are created when a rule is set with a
new label. The rules also take a timeout value (in seconds) as an option.
If more than one rule uses the same timer label, the timer will be
restarted whenever any of the rules get a hit.
One entry for each timer is created in sysfs. This attribute contains the
timer remaining for the timer to expire. The attributes are located under
the xt_idletimer class:
/sys/class/xt_hardidletimer/timers/<label>
When the timer expires, the target module sends a sysfs notification to the
userspace, which can then decide what to do (eg. disconnect to save power)
Compared to xt_IDLETIMER, xt_HARDIDLETIMER can send notifications when CPU
is in suspend too, to notify the timer expiry
