Linux-2.6.12-rc2 Initial git repository build. I'm not bothering with the full history, even though we have it. We can create a separate "historical" git archive of that later if we want to, and in the meantime it's about 3.2GB when imported into git - space that would just make the early git days unnecessarily complicated, when we don't have a lot of good infrastructure for it. Let it rip!

USB: serial: FTDI: add high speed device support Added support for FTDI's USB 2.0 hi-speed devices - FT2232H (2 interfaces) and FT4232H (4 interfaces), including a new baud rate calculation for these devices which can now achieve up to 12Mbaud by turning off a divide by 2.5 in the baud rate generator of the chips. In order to achieve baud rates of <1200 baud, the divide by 2.5 must be active. The default product ID of the FT2232H is 0x6010 (same as the FT2232C IC). The default PID of the FT4232H is 0x6011.

usb-serial: ftdi_sio: fix reference counting of ftdi_private This patch (as1238) adds proper reference counting for ftdi_sio's private data structure. Without it, the driver will free the structure while it is still in use if the user unplugs the serial device before closing the device file. The patch also replaces a slightly dangerous cancel_delayed_work/flush_scheduled_work pair with cancel_delayed_work_sync, which is always safer.

ft232: support the ASYNC_LOW_LATENCY flag This allows users to use the standard setserial command with this FT232 feature as well as obscure chip specific interfaces we have now. We keep track of and respect the sysfs value for non-low-latency cases. In theory we could do smart stuff with VTIME and the like but this seems of questionable worth.

USB: ftdi_sio: fix hi-speed device packet size calculation Added a function to set the packet size to be used based on the value from the device endpoint descriptor. The FT2232H and FT4232H hi-speed devices will have wMaxPacketSize of 512 bytes when connected to a USB 2.0 hi-speed host, but will use alternative descriptors with wMaxPacketSize of 64 bytes if connected to a USB 1.1 host or hub. All other FTDI devices have wMaxPacketSize of 64 bytes, except some FT232R and FT245R devices which customers have mistakenly programmed to have wMaxPacketSize of 0 - this is an error and will be overridden to use wMaxPacketSize of 64 bytes. The packet size used is important as it determines where the driver removes the status bytes from the incoming data. If it is incorrect, it will lead to data corruption. Signed-off-by: Mark J.

NDI has been providing this patch for various kernel flavors for several years and we would like to see these changes built in to the driver so that our equipement works without the need for customers to patch the kernel themselves. The patch makes small modifications to 2 files: ./drivers/usb/serial/ftdi_sio.c and ./drivers/usb/serial/ftdi_sio.h. It accomplishes 3 things: 1. Define the VID and PIDs to allow the driver to recognize the NDI devices. 2. Map the 19200 baud rate setting to our higher baud rate of 1.2Mb We would have chosen to map 38400 to the higher rate, similar to what several other vendors have done, but some of our legacy customers actually use 38400, therefore we remap 19200 to the higher rate. 3. We set the default transmit latency in the FTDI chip to 1ms for our devices. Our devices are typically polled at 60Hz and the default ftdi latency seriously affects turn-around time and results in missed data frames. We have created a modprobe option that allows this setting to be increased. This has proven necessary particularly in some virtualized environments. Signed-off-by: Martin P.

USB: ftdi_sio: Support for more JTAG adaptors [PATCH] ftdi_sio: add support for more FTDI based JTAG adaptors There are more devices similar to the Olimex JTAG adaptor, in that the first port of the FT2232C is used for JTAG, and only the second port is available as UART. I have thus renamed ftdi_olimex_{probe,quirk} to ftdi_jtag_{probe,quirk} and added vendor/product ID's for the OpenMoko Neo1973 Debug Board as well as the OOCDlink device. I've also updated the KERN_INFO message sent to userspace to remove the word 'olimex' and an extra '\n' that was causing an empty line in dmesg.

[PATCH] USB ftdi_sio: reduce device id table clutter ftdi_sio: Use a single usb_device_id table and detect the type of chip programatically. The table also flags devices requiring special initialization. The patch makes the driver about 10K smaller and makes it easier to add new device IDs.

Linux-2.6.12-rc2 Initial git repository build. I'm not bothering with the full history, even though we have it. We can create a separate "historical" git archive of that later if we want to, and in the meantime it's about 3.2GB when imported into git - space that would just make the early git days unnecessarily complicated, when we don't have a lot of good infrastructure for it.

With this it should be fairly straightforward to make at least lirc receiving work with this device.

USB: ftdi: support NDI devices It enhances the driver for FTDI-based USB serial adapters to recognize and support Northern Digital Inc (NDI) measurement equipment. NDI has been providing this patch for various kernel flavors for several years and we would like to see these changes built in to the driver so that our equipement works without the need for customers to patch the kernel themselves. The patch makes small modifications to 2 files: ./drivers/usb/serial/ftdi_sio.c and ./drivers/usb/serial/ftdi_sio.h. It accomplishes 3 things: 1. Define the VID and PIDs to allow the driver to recognize the NDI devices. 2. Map the 19200 baud rate setting to our higher baud rate of 1.2Mb We would have chosen to map 38400 to the higher rate, similar to what several other vendors have done, but some of our legacy customers actually use 38400, therefore we remap 19200 to the higher rate. 3. We set the default transmit latency in the FTDI chip to 1ms for our devices. Our devices are typically polled at 60Hz and the default ftdi latency seriously affects turn-around time and results in missed data frames. We have created a modprobe option that allows this setting to be increased. This has proven necessary particularly in some virtualized environments. Signed-off-by: Martin P.

[PATCH] USB serial ftdi_sio: Prevent userspace DoS This patch limits the amount of outstanding 'write' data that can be queued up for the ftdi_sio driver, to prevent userspace DoS attacks (or simple accidents) that use up all the system memory by writing lots of data to the serial port. The original patch was by Guillaume Autran, who in turn based it on the same mechanism implemented in the 'visor' driver. I (Ian Abbott) re-targeted the patch to the latest sources, fixed a couple of errors, renamed his new structure members, and updated the implementations of the 'write_room' and 'chars_in_buffer' methods to take account of the number of outstanding 'write' bytes. It seems to work fine, though at low baud rates it is still possible to queue up an amount of data that takes an age to shift (a job for another day!).

We can create a separate "historical" git archive of that later if we want to, and in the meantime it's about 3.2GB when imported into git - space that would just make the early git days unnecessarily complicated, when we don't have a lot of good infrastructure for it.

USB: serial: FTDI: add high speed device support Added support for FTDI's USB 2.0 hi-speed devices - FT2232H (2 interfaces) and FT4232H (4 interfaces), including a new baud rate calculation for these devices which can now achieve up to 12Mbaud by turning off a divide by 2.5 in the baud rate generator of the chips. In order to achieve baud rates of <1200 baud, the divide by 2.5 must be active. The default product ID of the FT2232H is 0x6010 (same as the FT2232C IC). The default PID of the FT4232H is 0x6011.

USB: ftdi: support NDI devices It enhances the driver for FTDI-based USB serial adapters to recognize and support Northern Digital Inc (NDI) measurement equipment. NDI has been providing this patch for various kernel flavors for several years and we would like to see these changes built in to the driver so that our equipement works without the need for customers to patch the kernel themselves. The patch makes small modifications to 2 files: ./drivers/usb/serial/ftdi_sio.c and ./drivers/usb/serial/ftdi_sio.h. It accomplishes 3 things: 1. Define the VID and PIDs to allow the driver to recognize the NDI devices. 2. Map the 19200 baud rate setting to our higher baud rate of 1.2Mb We would have chosen to map 38400 to the higher rate, similar to what several other vendors have done, but some of our legacy customers actually use 38400, therefore we remap 19200 to the higher rate. 3. We set the default transmit latency in the FTDI chip to 1ms for our devices. Our devices are typically polled at 60Hz and the default ftdi latency seriously affects turn-around time and results in missed data frames. We have created a modprobe option that allows this setting to be increased. This has proven necessary particularly in some virtualized environments. Signed-off-by: Martin P.

usb_serial: API all change USB serial likes to use port->tty back pointers for the real work it does and to do so without any actual locking. Unfortunately when you consider hangup events, hangup/parallel reopen or even worse hangup followed by parallel close events the tty->port and port->tty pointers are not guaranteed to be the same as port->tty is the active tty while tty->port is the port the tty may or may not still be attached to. So rework the entire API to pass the tty struct. For console cases we need to pass both for now. This shows up multiple drivers that immediately crash with USB console some of which have been fixed in the process.

The FT2232H and FT4232H hi-speed devices will have wMaxPacketSize of 512 bytes when connected to a USB 2.0 hi-speed host, but will use alternative descriptors with wMaxPacketSize of 64 bytes if connected to a USB 1.1 host or hub. All other FTDI devices have wMaxPacketSize of 64 bytes, except some FT232R and FT245R devices which customers have mistakenly programmed to have wMaxPacketSize of 0 - this is an error and will be overridden to use wMaxPacketSize of 64 bytes. The packet size used is important as it determines where the driver removes the status bytes from the incoming data. If it is incorrect, it will lead to data corruption. Signed-off-by: Mark J.

usb-serial: ftdi_sio: fix reference counting of ftdi_private This patch (as1238) adds proper reference counting for ftdi_sio's private data structure. Without it, the driver will free the structure while it is still in use if the user unplugs the serial device before closing the device file. The patch also replaces a slightly dangerous cancel_delayed_work/flush_scheduled_work pair with cancel_delayed_work_sync, which is always safer.

[PATCH] USB serial ftdi_sio: Prevent userspace DoS This patch limits the amount of outstanding 'write' data that can be queued up for the ftdi_sio driver, to prevent userspace DoS attacks (or simple accidents) that use up all the system memory by writing lots of data to the serial port. The original patch was by Guillaume Autran, who in turn based it on the same mechanism implemented in the 'visor' driver. I (Ian Abbott) re-targeted the patch to the latest sources, fixed a couple of errors, renamed his new structure members, and updated the implementations of the 'write_room' and 'chars_in_buffer' methods to take account of the number of outstanding 'write' bytes. It seems to work fine, though at low baud rates it is still possible to queue up an amount of data that takes an age to shift (a job for another day!).

[PATCH] USB: ftdi_sio: avoid losing received data in tty-ldisc ftdi_sio: Avoid losing bytes at tty-ldisc. This patch was originally developed by Daniel Smertnig. I (Ian Abbott) made a few changes. It has been tested by both Daniel and I, at least for raw, non-canonical receive data processing. Here is Daniel's original description of the patch: === During a project in which I was using a FTDI 232BM to transmit data at relative high speeds (625kBit/s), I noticed a problem where data was lost even if flow control was enabled: The FTDI-Driver receives 512 Bytes of data over USB at a time, which consists of 8 64-Byte packets. Subtracting the 2 bytes of status information included in each packet this gives 496 "real" data bytes per read. This data is passed (indirectly, via the flip buffers) to the tty line discipline which takes care of throttling when there the free buffer space reaches TTY_THRESHOLD_THROTTLE (128). Because the FTDI driver processes up to 496 bytes at a time, throttling won't happen in time and the line discipline will discard the remaining bytes. To avoid this the patch passes data in 62-byte blocks to the tty layer and checks the available space in the ldisc-buffers. If there isn't enough free space, processing the rest of the data is delayed using a workqueue. Note: The original problem should be easily reproducible with a userspace program which does slow & small reads. === Signed-off-by: Ian Abbott <abbotti@mev.co.uk> Signed-off-by: Daniel Smertnig <daniel.smertnig@gmail.com> Signed-off-by: Greg Kroah-Hartman <gregkh@suse.de>

All other FTDI devices have wMaxPacketSize of 64 bytes, except some FT232R and FT245R devices which customers have mistakenly programmed to have wMaxPacketSize of 0 - this is an error and will be overridden to use wMaxPacketSize of 64 bytes. The packet size used is important as it determines where the driver removes the status bytes from the incoming data. If it is incorrect, it will lead to data corruption. Signed-off-by: Mark J.

USB: ftdi: support NDI devices It enhances the driver for FTDI-based USB serial adapters to recognize and support Northern Digital Inc (NDI) measurement equipment. NDI has been providing this patch for various kernel flavors for several years and we would like to see these changes built in to the driver so that our equipement works without the need for customers to patch the kernel themselves. The patch makes small modifications to 2 files: ./drivers/usb/serial/ftdi_sio.c and ./drivers/usb/serial/ftdi_sio.h. It accomplishes 3 things: 1. Define the VID and PIDs to allow the driver to recognize the NDI devices. 2. Map the 19200 baud rate setting to our higher baud rate of 1.2Mb We would have chosen to map 38400 to the higher rate, similar to what several other vendors have done, but some of our legacy customers actually use 38400, therefore we remap 19200 to the higher rate. 3. We set the default transmit latency in the FTDI chip to 1ms for our devices. Our devices are typically polled at 60Hz and the default ftdi latency seriously affects turn-around time and results in missed data frames. We have created a modprobe option that allows this setting to be increased. This has proven necessary particularly in some virtualized environments. Signed-off-by: Martin P.

USB: ftdi_sio: Support for more JTAG adaptors [PATCH] ftdi_sio: add support for more FTDI based JTAG adaptors There are more devices similar to the Olimex JTAG adaptor, in that the first port of the FT2232C is used for JTAG, and only the second port is available as UART. I have thus renamed ftdi_olimex_{probe,quirk} to ftdi_jtag_{probe,quirk} and added vendor/product ID's for the OpenMoko Neo1973 Debug Board as well as the OOCDlink device. I've also updated the KERN_INFO message sent to userspace to remove the word 'olimex' and an extra '\n' that was causing an empty line in dmesg.

Fix oops on close of hot-unplugged FTDI serial converter Commit c45d6320 ("fix reference counting of ftdi_private") stopped ftdi_sio_port_remove() from directly freeing the port-private data, with the intention if the port was still open, it would be freed when ftdi_close() is eventually called and releases the last refcount on the structure. That's all very well, but ftdi_sio_port_remove() still contains a call to usb_set_serial_port_data(port, NULL) -- so by the time we get to ftdi_close() for the port which was unplugged, it _still_ oopses on dereferencing that NULL pointer, as it did before (and does in 2.6.29). The fix is just not to clear the private data in ftdi_sio_port_remove(). Then the refcount is properly reduced to zero when the final kref_put() happens in ftdi_close(). Remove a bogus comment too, while we're at it. And stop doing things inside "if (priv)" -- it must _always_ be there. Based loosely on an earlier patch by Daniel Mack, and suggestions by Alan Stern.

[PATCH] USB serial ftdi_sio: Prevent userspace DoS This patch limits the amount of outstanding 'write' data that can be queued up for the ftdi_sio driver, to prevent userspace DoS attacks (or simple accidents) that use up all the system memory by writing lots of data to the serial port. The original patch was by Guillaume Autran, who in turn based it on the same mechanism implemented in the 'visor' driver. I (Ian Abbott) re-targeted the patch to the latest sources, fixed a couple of errors, renamed his new structure members, and updated the implementations of the 'write_room' and 'chars_in_buffer' methods to take account of the number of outstanding 'write' bytes. It seems to work fine, though at low baud rates it is still possible to queue up an amount of data that takes an age to shift (a job for another day!).

usb_serial: API all change USB serial likes to use port->tty back pointers for the real work it does and to do so without any actual locking. Unfortunately when you consider hangup events, hangup/parallel reopen or even worse hangup followed by parallel close events the tty->port and port->tty pointers are not guaranteed to be the same as port->tty is the active tty while tty->port is the port the tty may or may not still be attached to. So rework the entire API to pass the tty struct. For console cases we need to pass both for now. This shows up multiple drivers that immediately crash with USB console some of which have been fixed in the process.

usb-serial: ftdi_sio: fix reference counting of ftdi_private This patch (as1238) adds proper reference counting for ftdi_sio's private data structure. Without it, the driver will free the structure while it is still in use if the user unplugs the serial device before closing the device file. The patch also replaces a slightly dangerous cancel_delayed_work/flush_scheduled_work pair with cancel_delayed_work_sync, which is always safer.

usb_serial: API all change USB serial likes to use port->tty back pointers for the real work it does and to do so without any actual locking. Unfortunately when you consider hangup events, hangup/parallel reopen or even worse hangup followed by parallel close events the tty->port and port->tty pointers are not guaranteed to be the same as port->tty is the active tty while tty->port is the port the tty may or may not still be attached to. So rework the entire API to pass the tty struct. For console cases we need to pass both for now. This shows up multiple drivers that immediately crash with USB console some of which have been fixed in the process. Longer term we need a proper tty as console abstraction Signed-off-by: Alan Cox <alan@redhat.com> Signed-off-by: Greg Kroah-Hartman <gregkh@suse.de> Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>

[PATCH] USB serial ftdi_sio: Prevent userspace DoS This patch limits the amount of outstanding 'write' data that can be queued up for the ftdi_sio driver, to prevent userspace DoS attacks (or simple accidents) that use up all the system memory by writing lots of data to the serial port. The original patch was by Guillaume Autran, who in turn based it on the same mechanism implemented in the 'visor' driver. I (Ian Abbott) re-targeted the patch to the latest sources, fixed a couple of errors, renamed his new structure members, and updated the implementations of the 'write_room' and 'chars_in_buffer' methods to take account of the number of outstanding 'write' bytes. It seems to work fine, though at low baud rates it is still possible to queue up an amount of data that takes an age to shift (a job for another day!).

The FT2232H and FT4232H hi-speed devices will have wMaxPacketSize of 512 bytes when connected to a USB 2.0 hi-speed host, but will use alternative descriptors with wMaxPacketSize of 64 bytes if connected to a USB 1.1 host or hub. All other FTDI devices have wMaxPacketSize of 64 bytes, except some FT232R and FT245R devices which customers have mistakenly programmed to have wMaxPacketSize of 0 - this is an error and will be overridden to use wMaxPacketSize of 64 bytes. The packet size used is important as it determines where the driver removes the status bytes from the incoming data. If it is incorrect, it will lead to data corruption. Signed-off-by: Mark J.

[PATCH] USB: ftdi_sio: avoid losing received data in tty-ldisc ftdi_sio: Avoid losing bytes at tty-ldisc. This patch was originally developed by Daniel Smertnig. I (Ian Abbott) made a few changes. It has been tested by both Daniel and I, at least for raw, non-canonical receive data processing. Here is Daniel's original description of the patch: === During a project in which I was using a FTDI 232BM to transmit data at relative high speeds (625kBit/s), I noticed a problem where data was lost even if flow control was enabled: The FTDI-Driver receives 512 Bytes of data over USB at a time, which consists of 8 64-Byte packets. Subtracting the 2 bytes of status information included in each packet this gives 496 "real" data bytes per read. This data is passed (indirectly, via the flip buffers) to the tty line discipline which takes care of throttling when there the free buffer space reaches TTY_THRESHOLD_THROTTLE (128). Because the FTDI driver processes up to 496 bytes at a time, throttling won't happen in time and the line discipline will discard the remaining bytes. To avoid this the patch passes data in 62-byte blocks to the tty layer and checks the available space in the ldisc-buffers. If there isn't enough free space, processing the rest of the data is delayed using a workqueue. Note: The original problem should be easily reproducible with a userspace program which does slow & small reads. === Signed-off-by: Ian Abbott <abbotti@mev.co.uk> Signed-off-by: Daniel Smertnig <daniel.smertnig@gmail.com> Signed-off-by: Greg Kroah-Hartman <gregkh@suse.de>

[PATCH] USB: ftdi_sio: avoid losing received data in tty-ldisc ftdi_sio: Avoid losing bytes at tty-ldisc. This patch was originally developed by Daniel Smertnig. I (Ian Abbott) made a few changes. It has been tested by both Daniel and I, at least for raw, non-canonical receive data processing. Here is Daniel's original description of the patch: === During a project in which I was using a FTDI 232BM to transmit data at relative high speeds (625kBit/s), I noticed a problem where data was lost even if flow control was enabled: The FTDI-Driver receives 512 Bytes of data over USB at a time, which consists of 8 64-Byte packets. Subtracting the 2 bytes of status information included in each packet this gives 496 "real" data bytes per read. This data is passed (indirectly, via the flip buffers) to the tty line discipline which takes care of throttling when there the free buffer space reaches TTY_THRESHOLD_THROTTLE (128). Because the FTDI driver processes up to 496 bytes at a time, throttling won't happen in time and the line discipline will discard the remaining bytes. To avoid this the patch passes data in 62-byte blocks to the tty layer and checks the available space in the ldisc-buffers. If there isn't enough free space, processing the rest of the data is delayed using a workqueue. Note: The original problem should be easily reproducible with a userspace program which does slow & small reads. === Signed-off-by: Ian Abbott <abbotti@mev.co.uk> Signed-off-by: Daniel Smertnig <daniel.smertnig@gmail.com> Signed-off-by: Greg Kroah-Hartman <gregkh@suse.de>

usb_serial: API all change USB serial likes to use port->tty back pointers for the real work it does and to do so without any actual locking. Unfortunately when you consider hangup events, hangup/parallel reopen or even worse hangup followed by parallel close events the tty->port and port->tty pointers are not guaranteed to be the same as port->tty is the active tty while tty->port is the port the tty may or may not still be attached to. So rework the entire API to pass the tty struct. For console cases we need to pass both for now. This shows up multiple drivers that immediately crash with USB console some of which have been fixed in the process. Longer term we need a proper tty as console abstraction Signed-off-by: Alan Cox <alan@redhat.com> Signed-off-by: Greg Kroah-Hartman <gregkh@suse.de> Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>

USB: ftdi: support NDI devices It enhances the driver for FTDI-based USB serial adapters to recognize and support Northern Digital Inc (NDI) measurement equipment. NDI has been providing this patch for various kernel flavors for several years and we would like to see these changes built in to the driver so that our equipement works without the need for customers to patch the kernel themselves. The patch makes small modifications to 2 files: ./drivers/usb/serial/ftdi_sio.c and ./drivers/usb/serial/ftdi_sio.h. It accomplishes 3 things: 1. Define the VID and PIDs to allow the driver to recognize the NDI devices. 2. Map the 19200 baud rate setting to our higher baud rate of 1.2Mb We would have chosen to map 38400 to the higher rate, similar to what several other vendors have done, but some of our legacy customers actually use 38400, therefore we remap 19200 to the higher rate. 3. We set the default transmit latency in the FTDI chip to 1ms for our devices. Our devices are typically polled at 60Hz and the default ftdi latency seriously affects turn-around time and results in missed data frames. We have created a modprobe option that allows this setting to be increased. This has proven necessary particularly in some virtualized environments. Signed-off-by: Martin P.
