2407008b6e drivers/ramdisk.c and include/nuttx/fs/ramdisk.h: Add logic to dispose of the drvier and RAM buffer when the RAM disk has been unlinked and all open references to the RAM disk have been closed. Add new parameters to romdisk() to specify what should be done with the RAM/ROM buffer -- Should it be freed or not? Changed all calls to ramdisk() to use these new parameters. 2015-02-01 07:24:16 -06:00

eb1aca3e46 Add an unlink method to block driver interface. Same motivataion as for the same modification to the character driver interface 2015-01-31 13:19:23 -06:00

62e588a0a4 VFS: Add an unlink method to the character driver interface. This is important because if the character driver inode is unlinked and there are no open references to the driver, then the driver resources will be stranded. On the unlink call, the driver has the opportunity (1) check if there an any open references, and (2) if not free the driver resources 2015-01-31 11:31:34 -06:00

e86d00913e Unix domain/FIFOs: Fix a race condition between FIFO buffer operations and the opening and closing of FIFOs which necessary when the FIFOs are used to support Unix domain, datagram sockets. The default policy is the deallocate FIFO buffering when the last client closes the pipe. When when used for datagram communicatinos, packets left in the FIFO will be lost. Some like UDP read-ahead is needed: The buffered data in the FIFO needs to be retained until the reader gets a chance to re-open the FIFO. Added an ioctl (PIPEIOC_POLICY) to control the buffer policy. Default (0) is the legacy behavior; Unix domain datagram logic sets the alternative policy so that the packet data persists after the FIFO is closed. 2015-01-30 11:14:24 -06:00

e31d5125ae Add support for a variadic ioctl() function. The ioctl() interface is a non-standard, Unix interface. NuttX has always used the older, three-parameter version. Most contemporary systems now, however, use a variadic form of the ioctl() function. Added an option to insert a shim layer to adapt the three-parameter ioctl() to use the variadic interface form. Internally, the ioctl handling is the same three-parameter logic. The only real complexity to the shim is in how the system calls must be handled. 2014-11-29 10:53:22 -06:00
