Adjust the prototype to only pass the if_settings sub-structure in place of the ifreq, and remove the redundant 'cmd' argument in the process.

2021-05-13tty: cumulate and document tty_struct::flow* membersJiri Slaby1-4/+4
Group the flow flags under a single struct called flow. The new struct contains 'stopped' and 'tco_stopped' bools which used to be bits in a bitfield. The struct also contains the lock protecting them to potentially share the same cache line. Note that commit c545b66c6922b (tty: Serialize tcflow() with other tty flow control changes) added a padding to the original bitfield. It was for the bitfield to occupy a whole 64b word to avoid interferring stores on Alpha (cannot we evaporate this arch with weird implications to C code yet?). But it doesn't work as expected as the padding (tty_struct::unused) is aligned to a 8B boundary too and occupies some bytes from the next word. So make it reliable by: 1) setting __aligned of the struct -- that aligns the start, and 2) making 'unsigned long unused[0]' as the last member of the struct -- pads the end. This is also the perfect time to start the documentation of tty_struct where all this lives. So we start by documenting what these bools actually serve for. And why we do all the alignment dances. Only the few up-to-date information from the Theodore's comment made it into this new Kerneldoc comment. Signed-off-by: Jiri Slaby <jslaby@suse.cz> Cc: "David S.

Introduce helpers tty_port_set_initialized() and tty_port_initialized() to abstract atomic bit ops. Note: the transforms for test_and_set_bit() and test_and_clear_bit() are unnecessary as the state transitions are already mutually exclusive; the tty lock prevents concurrent open/close/hangup.

2015-10-17tty: Remove ASYNC_CLOSING checks in open()/hangup() methodsPeter Hurley1-9/+0
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 Hurley1-1/+1
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 Bergmann1-2/+2
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 Perches1-13/+13
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 Slaby1-1/+4
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.
