2015-10-17tty: Remove ASYNC_CLOSING checks in open()/hangup() methodsPeter Hurley
Since at least before 2.6.30, tty drivers that do not drop the tty lock while closing cannot observe ASYNC_CLOSING set while holding the tty lock; this includes the tty driver's open() and hangup() methods, since the tty core calls these methods holding the tty lock. For these drivers, waiting for ASYNC_CLOSING to clear while opening is not required, since this condition cannot occur. Similarly, even when the open() method drops and reacquires the tty lock after blocking, ASYNC_CLOSING cannot be set (again, for drivers that do not drop the tty lock while closing). Now that tty port drivers no longer drop the tty lock while closing (since 'tty: Remove tty_wait_until_sent_from_close()'), the same conditions apply: waiting for ASYNC_CLOSING to clear while opening is not required, nor is re-checking ASYNC_CLOSING after dropping and reacquiring the tty lock while blocking (eg., in *_block_til_ready()). Note: The ASYNC_CLOSING flag state is still maintained since several bitrotting drivers use it for (dubious) other purposes.

2014-07-10tty: Remove tty_hung_up_p() tests from tty drivers' open()Peter Hurley
Since at least before 2.6.30, it has not been possible to observe a hung up file pointer in a tty driver's open() method unless/until the driver open() releases the tty_lock() (eg., before blocking). This is because tty_open() adds the file pointer while holding the tty_lock() _and_ doesn't release the lock until after calling the tty driver's open() method. [ Before tty_lock(), this was lock_kernel(). ] Since __tty_hangup() first waits on the tty_lock() before enumerating and hanging up the open file pointers, either __tty_hangup() will wait for the tty_lock() or tty_open() will not yet have added the file pointer. For example, CPU 0 | CPU 1 | tty_open | __tty_hangup .. | .. tty_lock | .. tty_reopen | tty_lock / blocks .. | tty_add_file(tty, filp) | .. | tty->ops->open(tty, filp) | tty_port_open | tty_port_block_til_ready | .. | while (1) | .. | tty_unlock | / unblocks schedule | for each filp on tty->tty_files | f_ops = tty_hung_up_fops; | .. | tty_unlock tty_lock | .. | tty_unlock | Note that since tty_port_block_til_ready() and similar drop the tty_lock while blocking, when woken, the file pointer must then be tested for having been hung up. Also, fix bit-rotted drivers that used extra_count to track the port->count bump. CC: Mikael Starvik <starvik@axis.com> CC: Samuel Ortiz <samuel@sortiz.org> CC: "David S.

2014-01-07tty: synclink: avoid sleep_on raceArnd Bergmann
The four variants of the synclink driver use the same code in their open() callback to wait for a port in process of being closed, using interruptible_sleep_on, which is racy and going away soon. Making things worse, these functions hold the BTM while doing so, which means that if we ever enter this code path, we cannot actually continue since the other thread that is in process of closing the port can no longer get the BTM. This addresses both issues by using wait_event_interruptible_tty() instead.

2013-01-30TTY: synclink: Convert + to | for bit operationsJoe Perches
Dan Carpenter noticed a missing set of parentheses around a multiple field addition. https://lkml.org/lkml/2013/1/27/166 His original commit message: There is a kind of precedence problem here, but it doesn't affect how the code works because ->serial_signals is unsigned char. We want to clear two flags here. #define SerialSignal_RTS 0x20 /* Request to Send */ #define SerialSignal_DTR 0x80 /* Data Terminal Ready */ Without the parenthesis then it does: info->serial_signals &= 0x5f; With the parenthesis it does: info->serial_signals &= 0xffffff5f; info->serial_signals is an unsigned char so the two statements are equivalent, but it's cleaner to add the parenthesis. In other dtr_rts() functions the parenthesis are there so this makes it more consistent. Other changes: Convert all + uses to | for these bit operations. Reorder the multiple fields for consistency.

2012-11-15TTY: call tty_port_destroy in the rest of driversJiri Slaby
After commit "TTY: move tty buffers to tty_port", the tty buffers are not freed in some drivers. This is because tty_port_destructor is not called whenever a tty_port is freed. This was an assumption I counted with but was unfortunately untrue. So fix the drivers to fulfil this assumption. To be sure, the TTY buffers (and later some stuff) are gone along with the tty_port, we have to call tty_port_destroy at tear-down places. This is mostly where the structure containing a tty_port is freed. This patch does exactly that -- put tty_port_destroy at those places.

2010-09-29pcmcia: introduce autoconfiguration featureDominik Brodowski
Introduce an autoconfiguration feature to set certain values in pcmcia_loop_config(), instead of copying the same code over and over in each PCMCIA driver. At first, introduce the following options: CONF_AUTO_CHECK_VCC check or matching Vcc entry CONF_AUTO_SET_VPP set Vpp CONF_AUTO_AUDIO enable the speaker line CC: netdev@vger.kernel.org CC: linux-wireless@vger.kernel.org CC: linux-ide@vger.kernel.org CC: linux-usb@vger.kernel.org CC: laforge@gnumonks.org CC: linux-mtd@lists.infradead.org CC: alsa-devel@alsa-project.org CC: linux-serial@vger.kernel.org CC: Jiri Kosina <jkosina@suse.cz> CC: linux-scsi@vger.kernel.org Acked-by: Gustavo F.

2010-09-29pcmcia: convert pcmcia_request_configuration to pcmcia_enable_deviceDominik Brodowski
pcmcia_enable_device() now replaces pcmcia_request_configuration(). Instead of config_req_t, all necessary flags are either passed as a parameter to pcmcia_enable_device(), or (in rare circumstances) set in struct pcmcia_device -> flags. With the last remaining user of include/pcmcia/cs.h gone, remove all references.

2010-09-29pcmcia: move config_{base,index,regs} to struct pcmcia_deviceDominik Brodowski
Several drivers prefer to explicitly set config_{base,index,regs}, formerly known as ConfigBase, ConfigIndex and Present. Instead of passing these values inside config_req_t, store it in struct pcmcia_device.

2010-09-29pcmcia: simplify IntTypeDominik Brodowski
IntType was only set to INT_MEMORY (driver pcmciamtd) or INT_MEMORY_AND_IO (all other drivers). As this flags seems to relate to ioport access, make it conditional to the driver having requested IO port access. There are two drivers which do not request IO ports, but did set INT_MEMORY_AND_IO: ray_cs and b43. For those, we consistently only set INT_MEMORY in future.

2010-08-03pcmcia: do not use io_req_t when calling pcmcia_request_io()Dominik Brodowski
Instead of io_req_t, drivers are now requested to fill out struct pcmcia_device *p_dev->resource[0,1] for up to two ioport ranges. After a call to pcmcia_request_io(), the ports found there are reserved, after calling pcmcia_request_configuration(), they may be used.

2010-08-03pcmcia: do not use io_req_t after call to pcmcia_request_io()Dominik Brodowski
After pcmcia_request_io(), do not make use of the values stored in io_req_t, but instead use those found in struct pcmcia_device->resource[].

2010-07-30pcmcia: remove cs_types.hDominik Brodowski
Remove cs_types.h which is no longer needed: Most definitions aren't used at all, a few can be made away with, and two remaining definitions (typedefs, unfortunatley) may be moved to more specific places.
