A read() from a pty master may mistakenly indicate EOF (errno == -EIO)
after the pty slave has closed, even though input data remains to be read.
For example,
pty slave | input worker | pty master
| |
| | n_tty_read()
pty_write() | | input avail? no
add data | | sleep
schedule worker --->| | .
|---> flush_to_ldisc() | .
pty_close() | fill read buffer | .
wait for worker | wakeup reader --->| .
| read buffer full? |---> input avail ? yes
|<--- yes - exit worker | copy 4096 bytes to user
TTY_OTHER_CLOSED <---| |<--- kick worker
| |
**** New read() before worker starts ****
| | n_tty_read()
| | input avail? no
| | TTY_OTHER_CLOSED? yes
| | return -EIO
Several conditions are required to trigger this race:
1. the ldisc read buffer must become full so the input worker exits
2. the read() count parameter must be >= 4096 so the ldisc read buffer
is empty
3. the subsequent read() occurs before the kicked worker has processed
more input
However, the underlying cause of the race is that data is pipelined, while
tty state is not; ie., data already written by the pty slave end is not
yet visible to the pty master end, but state changes by the pty slave end
are visible to the pty master end immediately.
Pipeline the TTY_OTHER_CLOSED state through input worker to the reader.
1. Introduce TTY_OTHER_DONE which is set by the input worker when
TTY_OTHER_CLOSED is set and either the input buffers are flushed or
input processing has completed. Readers/polls are woken when
TTY_OTHER_DONE is set.
2. Reader/poll checks TTY_OTHER_DONE instead of TTY_OTHER_CLOSED.
3. A new input worker is started from pty_close() after setting
TTY_OTHER_CLOSED, which ensures the TTY_OTHER_DONE state will be
set if the last input worker is already finished (or just about to
exit).
Remove tty_flush_to_ldisc(); no in-tree callers.

when gsmtty_remove put dlci, it will cause memory leak if dlci->port's refcount is zero.
So we do the cleanup work in .cleanup callback instead.
dlci will be last put in two call chains.
1) gsmld_close -> gsm_cleanup_mux -> gsm_dlci_release -> dlci_put
2) gsmld_remove -> dlci_put
so there is a race. the memory leak depends on the race.
In call chain 2. we hit the memory leak. below comment tells.
release_tty -> tty_driver_remove_tty -> gsmtty_remove -> dlci_put -> tty_port_destructor (WARN_ON(port->itty) and return directly)
|
tty->port->itty = NULL;
|
tty_kref_put ---> release_one_tty -> gsmtty_cleanup (added by our patch)
So our patch fix the memory leak by doing the cleanup work after tty core did.

the remove callback will be called in two cases, 1) if the driver is

cleanups were being done in the module unload section so if the module
is unloaded everything works. But if the pci device is removed then the
loaded driver will be left in an inconsistent state.
So moved the cleanups in the remove callback and since there was no

pci_driver in the function.

The code for determining which board type matches the PCI device ID is
over-the-top since only a single board type is supported. Also, the
method it uses match the PCI device ID to a board type is a little
antiquated. Most comedi drivers for PCI devices use `driver_data` from
the probed PCI device as an index into an array of supported board
types, but "gsc_hpdi" uses a `for` loop to find an element of
`hpdi_boards[]` that matches the PCI device. The only thing in
`hpdi_boards[]` not used for finding a matching PCI device is the `name`
member of `struct hpdi_board` which points to a string literal and ends
up getting assigned to `dev->board_name`.
Get rid of the multiple board type support, and set `dev->board_name` to
point to the original string literal pointed to by
`hpdi_boards[0].name`. This string is visible to userspace.

Pull user-namespace fix from Eric Biederman:
"Eric Windish recently reported a really bug that allows mounting fresh
copies of proc and sysfs when it really should not be allowed. The
code attempted to verify that proc and sysfs were fully visible but
there is a test missing to ensure that the root of the filesystem is
visible. Doh!
The following patch fixes that.
This fixes a containment issue that the docker folks are seeing"

Pull irq updates from Thomas Gleixner:
"Two patches from the irq departement:
- a simple fix to make dummy_irq_chip usable for wakeup scenarios
- removal of the gic arch_extn hackery. Now that all users are
converted we really want to get rid of the interface so people wont
come up with new use cases"

keeping it active"

transfer_buffer_length is of type u32. It's therefore wrong to assign it
to a signed integer. This patch avoids the overflow.
It's worth noting that entry->length here is a long; perhaps it would be
beneficial at somepoint to change this to be unsigned as well, if
nothing else relies on its signedness for error conditions or the like.

This patch should have been part of the previous patch having the
same summary. See http://marc.info/?l=linux-kernel&m=143039470103795&w=2
Unfortunately, I didn't check to see where else this lock was used before
submitting that patch. This should take care of it for netxen_nic, as I
did a thorough search this time.
To recap from the original patch; although testing this driver with
DEBUG_LOCKDEP and DEBUG_SPINLOCK enabled did not produce any traces,
it would be more prudent in the case of tx_clean_lock to use _bh
versions of spin_[un]lock, since this lock is manipulated in both
the process and softirq contexts.
This patch was tested for functionality and regressions with netperf
and DEBUG_LOCKDEP and DEBUG_SPINLOCK enabled.

The amd-xgbe driver currently only works with the Seattle SoC, which
is ARM64 architecture, so there is no point in building this driver on
other architectures except for build testing purpose. The dependency
list can be updated later if the driver ever supports other
architectures.

When tcf_destroy() returns true, tp could be already destroyed,
we should not use tp->next after that.
For long term, we probably should move tp list to list_head.

The same hardware issue the at91 must work around applies to at least the
Zynq ethernet, and possibly more devices. The driver also needs to handle
the RXUBR interrupt since it turns it on with MACB_RX_INT_FLAGS anyway.
