* | pty: avoid forcing 'low_latency' tty flagOGAWA Hirofumi2009-07-29
|/ | | | | | | | | | | | | | | | | | | | | | | We really don't want to mark the pty as a low-latency device, because as Alan points out, the ->write method can be called from an IRQ (ppp?), and that means we can't use ->low_latency=1 as we take mutexes in the low_latency case. So rather than using low_latency to force the written data to be pushed to the ldisc handling at 'write()' time, just make the reader side (or the poll function) do the flush when it checks whether there is data to be had. This also fixes the problem with lost data in an emacs compile buffer (bugzilla 13815), and we can thus revert the low_latency pty hack (commit 3a54297478e6578f96fd54bf4daa1751130aca86: "pty: quickfix for the pty ENXIO timing problems").

* specialix.c: convert nested spin_lock_irqsave to spin_lockJulia Lawall2009-07-20
| | | | | | | | | | | | | | | | | | | | | | | | | | If spin_lock_irqsave is called twice in a row with the same second argument, the interrupt state at the point of the second call overwrites the value saved by the first call. Indeed, the second call does not need to save the interrupt state, so it is changed to a simple spin_lock. The semantic match that finds this problem is as follows: (http://www.emn.fr/x-info/coccinelle/) // <smpl> @@ expression lock1,lock2; expression flags; @@ *spin_lock_irqsave(lock1,flags) ... when != flags *spin_lock_irqsave(lock2,flags) // </smpl> Signed-off-by: Julia Lawall <julia@diku.dk> Signed-off-by: Alan Cox <alan@linux.intel.com> Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>

| | | | | | | | | | | | | | | | | The buffer for the consoles are unconditionally allocated at con_init() time, which miss the creation of the vcs(a) devices.

* n_tty: Fix echo raceAlan Cox2009-07-16
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | If a tty in N_TTY mode with echo enabled manages to get itself into a state where - echo characters are pending - FASYNC is enabled - tty_write_wakeup is called from either - a device write path (pty) - an IRQ (serial) then it either deadlocks or explodes taking a mutex in the IRQ path. On the serial side it is almost impossible to reproduce because you have to go from a full serial port to a near empty one with echo characters pending. The pty case happens to have become possible to trigger using emacs and ptys, the pty changes having created a scenario which shows up this bug. The code path is n_tty:process_echoes() (takes mutex) tty_io:tty_put_char() pty:pty_write (or serial paths) tty_wakeup (from pty_write or serial IRQ) n_tty_write_wakeup() process_echoes() *KABOOM* Signed-off-by: Alan Cox <alan@linux.intel.com> Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>

* vt: drop bootmem/slab memory distinctionJohannes Weiner2009-07-16
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Bootmem is not used for the vt screen buffer anymore as slab is now available at the time the console is initialized. Get rid of the now superfluous distinction between slab and bootmem, it's always slab. This also fixes a kmalloc leak which Catalin described thusly: Commit a5f4f52e ("vt: use kzalloc() instead of the bootmem allocator") replaced the alloc_bootmem() with kzalloc() but didn't set vc_kmalloced to 1 and the memory block is later leaked.

* tty: Fix the leak in tty_ldisc_releaseAlan Cox2009-06-29
| | | | | | | | | | | | | | | | | | | | | Currently we reinit the ldisc on final tty close which is what the old code did to ensure that if the device retained its termios settings then it had the right ldisc. tty_ldisc_reinit does that but also leaves us with the reset ldisc reference which is then leaked. At this point we know the port will be recycled so we can kill the ldisc off completely rather than try and add another ldisc free up when the kref count hits zero. At this point it is safe to keep the ldisc closed as tty_ldisc waiting methods are only used from the user side, and as the final close we are the last such reference. Interrupt/driver side methods will always use the non wait version and get back a NULL. Found with kmemleak and investigated/identified by Catalin Marinas.

Alright, I've reworked this now so that if we get one of these cases where there's a bsr that's > 4k and < 64k on a 64k kernel we'll only advertise that it is a 4k BSR to userspace. I think this is the best solution since user programs are only supposed to look at sysfs to determine how much can be mapped, and libbsr does this as well.

The number of ports actually available per device is stored in moxa_board_conf->numPorts. This number is not considered in moxa_open(). Opening a port that is not available results in a kernel oops. This patch adds a test to moxa_open() that prevents opening unavailable ports.

Its behavior is dependent on a few compile time and run time factors that alter its behavior which is really unnecessecary. If CONFIG_KEXEC is not configured, sysrq-c, crashes the system with a NULL pointer dereference. If CONFIG_KEXEC is configured, it calls crash_kexec directly, which implies that the kexec kernel will either be booted (if its been previously loaded), or it will simply do nothing (the no kexec kernel has been loaded). It would be much easier to just simplify the whole thing to dereference a NULL pointer all the time regardless of configuration. That way, it will always try to crash the system, and if a kexec kernel has been loaded into reserved space, it will still boot from the page fault trap handler (assuming panic_on_oops is set appropriately).

This results in spamming of the kernel log with "... registered pardevice" "... unregistered pardevice" These messages are completely useless, except for debugging ppdev, probably. So put them under DEBUG (or dynamic debug).
