| * firewire: core: use correct vendor/model IDsClemens Ladisch2015-02-021-2/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The kernel was using the vendor ID 0xd00d1e, which was inherited from the old ieee1394 driver stack. However, this ID was not registered, and invalid. Instead, use the vendor/model IDs that are now officially assigned to the kernel: https://ieee1394.wiki.kernel.org/index.php/IEEE_OUI_Assignments [stefanr: - The vendor ID 001f11 is Openmoko, Inc.'s identifier, registered at IEEE Registration Authority. - The range of model IDs 023900...0239ff are the Linux kernel 1394 subsystem's identifiers, registered at Openmoko. - Model ID 023901 is picked by the subsystem developers as firewire-core's model ID.] Signed-off-by: Clemens Ladisch <clemens@ladisch.de> Signed-off-by: Stefan Richter <stefanr@s5r6.in-berlin.de>

| | | | | | | | | | | | | | | | | | | | | | | | | | | | [Bart van Asche:] SCSI core never sets cmd->sc_data_direction to DMA_BIDIRECTIONAL; scsi_bidi_cmnd(cmd) should be used instead to test for a bidirectional command. [Christoph Hellwig:] Bidirectional commands won't ever be queued anyway, unless a LLD or transport driver sets QUEUE_FLAG_BIDI. So, simply remove the respective queuecommand check in the SBP-2 transport driver. Signed-off-by: Stefan Richter <stefanr@s5r6.in-berlin.de>

* firewire: sbp2: replace card lock by target lockStefan Richter2014-12-101-31/+29
| | | | | | | | | | | | | firewire-core uses fw_card.lock to protect topology data and transaction data. firewire-sbp2 uses fw_card.lock for entirely unrelated purposes. Introduce a sbp2_target.lock to firewire-sbp2 and replace all fw_card.lock uses in the driver. fw_card.lock is now entirely private to firewire-core. This has no immediate advantage apart from making it clear in the code that firewire-sbp2 does not interact with the core via the core lock. Signed-off-by: Stefan Richter <stefanr@s5r6.in-berlin.de>

* firewire: sbp2: protect a reference counter properlyStefan Richter2014-12-101-8/+6
| | | | | | | | | | | | | | The assertion in the comment in sbp2_allow_block() is no longer true. Or maybe it never was true. At least now, the sole caller of sbp2_allow_block(), sbp2_login, can run concurrently to one of sbp2_unblock()'s callers, sbp2_remove. sbp2_login is performed by sbp2_logical_unit.work. sbp2_remove is performed by fw_device.work. sbp2_remove cancels sbp2_logical_unit.work, but only after it called sbp2_unblock.

* firewire: core: document fw_csr_string's truncation of long stringsStefan Richter2014-12-101-0/+3
| | | | | | | | | | | fw_csr_string() truncates and terminates target strings like strlcpy() does. Unlike strlcpy(), it returns the target strlen, not the source strlen, hence users of fw_csr_string() are unable to detect truncation. Point this behavior out in the kerneldoc comment.

* firewire: cdev: prevent kernel stack leaking into ioctl argumentsStefan Richter2014-11-141-2/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Found by the UC-KLEE tool: A user could supply less input to firewire-cdev ioctls than write- or write/read-type ioctl handlers expect. The handlers used data from uninitialized kernel stack then. This could partially leak back to the user if the kernel subsequently generated fw_cdev_event_'s (to be read from the firewire-cdev fd) which notably would contain the _u64 closure field which many of the ioctl argument structures contain. The fact that the handlers would act on random garbage input is a lesser issue since all handlers must check their input anyway. The fix simply always null-initializes the entire ioctl argument buffer regardless of the actual length of expected user input. That is, a runtime overhead of memset(..., 40) is added to each firewirew-cdev ioctl() call. [Comment from Clemens Ladisch: This part of the stack is most likely to be already in the cache.] Remarks: - There was never any leak from kernel stack to the ioctl output buffer itself. IOW, it was not possible to read kernel stack by a read-type or write/read-type ioctl alone; the leak could at most happen in combination with read()ing subsequent event data. - The actual expected minimum user input of each ioctl from include/uapi/linux/firewire-cdev.h is, in bytes: [0x00] = 32, [0x05] = 4, [0x0a] = 16, [0x0f] = 20, [0x14] = 16, [0x01] = 36, [0x06] = 20, [0x0b] = 4, [0x10] = 20, [0x15] = 20, [0x02] = 20, [0x07] = 4, [0x0c] = 0, [0x11] = 0, [0x16] = 8, [0x03] = 4, [0x08] = 24, [0x0d] = 20, [0x12] = 36, [0x17] = 12, [0x04] = 20, [0x09] = 24, [0x0e] = 4, [0x13] = 40, [0x18] = 4.

Some of it definitely belongs into the ugly code museum. - Consolidation of the timekeeping interface zoo. - A fast NMI safe accessor to clock monotonic for tracing. This is a long standing request to support correlated user/kernel space traces. With proper NTP frequency correction it's also suitable for correlation of traces accross separate machines. - Checkpoint/restart support for timerfd. - A few NOHZ[_FULL] improvements in the [hr]timer code. - Code move from kernel to kernel/time of all time* related code. - New clocksource/event drivers from the ARM universe. I'm really impressed that despite an architected timer in the newer chips SoC manufacturers insist on inventing new and differently broken SoC specific timers. [ Ed. "Impressed"?

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | In post commit, a quirk of this firmware about transactions is reported. This commit apply a workaround for this quirk. They often fail transactions due to gap_count mismatch. This state is changed by generating bus reset. The fw_schedule_bus_reset() is an exported symbol in firewire-core. But there are no header for public. This commit moves its prototype from drivers/firewire/core.h to include/linux/firewire.h. This mismatch still affects bus management before generating this bus reset. It still takes a time to call driver's probe() because transactions are still often failed.

VT6315 Series Firewire Controller [1106:3403] I now got a card with $ lspci -nn VIA Technologies, Inc. VT6315 Series Firewire Controller [1106:3403] (rev 01) and this works fine with MSI enabled. Second, I tested this VT6315 rev 1 without CYCLE_TIMER quirk flag using http://me.in-berlin.de/~s5r6/linux1394/utils/test_cycle_time_v20100125.c and found that this chip does in fact access the cycle timer atomically. Things I can't test because I don't have the hardware: - whether VT6315 rev 0 really needs QUIRK_CYCLE_TIMER, - whether the VT6320 PCI device needs QUIRK_CYCLE_TIMER, - whether the VT6325 and VT6330 PCIe devices need QUIRK_CYCLE_TIMER and QUIRK_NO_MSI. Hence, just add a whitelist entry specifically for VT6315 rev >= 1 without any quirk flags. Before this entry we need an extra entry to catch VT6315 rev <= 0 due to how our ID matching logic works.

|/ | | | | | | | | | | | | | | | | | | | Undo a feature introduced in v3.14 by commit fcd46b34425d "firewire: Enable remote DMA above 4 GB". That change raised the minimum address at which protocol drivers and user programs can register for request reception from 0x0001'0000'0000 to 0x8000'0000'0000. It turned out that at least one vendor-specific protocol exists which uses lower addresses: https://bugzilla.kernel.org/show_bug.cgi?id=76921 For the time being, revert most of commit fcd46b34425d so that affected protocols work like with kernel v3.13 and before. Just keep the valid documentation parts from the regressing commit, and the ability to identify controllers which could be programmed to accept >32 bit physical DMA addresses. The rest of fcd46b34425d should probably be brought back as an optional instead of default feature.

They have few users and a nasty surprise in terms of reentrancy guarantee as workqueue considers work items to be different if they don't have the same work function. firewire core-device and sbp2 have been been multiplexing work items with multiple work functions. Introduce fw_device_workfn() and sbp2_lu_workfn() which invoke fw_device->workfn and sbp2_logical_unit->workfn respectively and always use the two functions as the work functions and update the users to set the ->workfn fields instead of overriding work functions using PREPARE_DELAYED_WORK(). This fixes a variety of possible regressions since a2c1c57be8d9 "workqueue: consider work function when searching for busy work items" due to which fw_workqueue lost its required non-reentrancy property.

The link shall not assert LReq until the reset is complete." In other words, the link needs to give the PHY at least 10 ms to get the interface operational. With just the msleep(1) in bd972688eb24, the first read_phy_reg() during ohci_enable() may happen before the phy-link interface reset was finished, and fail. Due to the high variability of msleep(n) with small n, this failure was not fully reproducible, and not apparent at all with low CONFIG_HZ setting. On the other hand, Peter can no longer reproduce the issue with FW643 rev8. The read phy reg failures that happened back then may have had an unrelated cause. So, just revert bd972688eb24, except for the valid comment on TSB82AA2 cards.

* firewire: Enable remote DMA above 4 GBStefan Richter2014-01-203-6/+11
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This makes all of a machine's memory accessible to remote debugging via FireWire, using the physical response unit (i.e. RDMA) of OHCI-1394 link layer controllers. This requires actual support by the controller. The only ones currently known to support it are Agere/LSI FW643. Most if not all other OHCI-1394 controllers do not implement the optional Physical Upper Bound register. With them, RDMA will continue to be limited to the lowermost 4 GB. firewire-ohci's startup message in the kernel log is augmented to tell whether the controller does expose more than 4 GB to RDMA. While OHCI-1394 allows for a maximum Physical Upper Bound of 0xffff'0000'0000 (near 256 TB), this implementation sets it to 0x8000'0000'0000 (128 TB) in order to avoid interference with applications that require interrupt-served asynchronous request reception at respectively low addresses. Note, this change does not switch remote DMA on. It only increases the range of remote access to all memory (instead of just 4 GB) whenever remote DMA was switched on by other means. The latter is achieved by setting firewire-ohci's remote_dma parameter, or if the physical DMA filter is opened through firewire-sbp2.

This can lead to adapter firmware hangs or excessive I/O errors. This patch disables WRITE SAME for devices connected to host adapters that provide an emulated target.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | Put bus_reset_work into its own workqueue. By doing this, forward progress of bus_reset_work() is guaranteed if the work is switched over to a rescuer thread. Switching work to a rescuer thread happens if a new worker thread could not be allocated in certain time (MAYDAY_INITIAL_TIMEOUT, typically 10 ms). This might not be possible under high memory pressure or even on a heavily loaded embedded system running a slow serial console. The former deadlock occured in the following situation: The rescuer thread ran fw_device_init->read_config_rom->read_rom->fw_run_transaction. fw_run_transaction blocked waiting for the completion object. This completion object would have been completed in bus_reset_work, but this work was never executed in the rescuer thread due to its strictly sequential behaviour. [Stefan R.: Removed WQ_NON_REENTRANT flag from allocation because it is no longer needed in current kernels. Add it back if you backport to kernels older than 3.7, i.e. one which does not contain dbf2576e37da "workqueue: make all workqueues non-reentrant".

| | | | | | | | | | | | | | | | | | | | | | | | | FireWire upper layer drivers are converted from generic struct driver.probe() and .remove() to bus-specific struct fw_driver.probe() and .remove(). The new .probe() adds a const struct ieee1394_device_id *id argument, indicating the entry in the driver's device identifiers table which matched the fw_unit to be probed. This new argument is used by the snd-firewire-speakers driver to look up device-specific parameters and methods. There is at least one other FireWire audio driver currently in development in which this will be useful too. The new .remove() drops the unused error return code. Although all in-tree drivers are being converted to the new methods, support for the old methods is left in place in this commit. This allows public developer trees to merge this commit and then move to the new fw_driver methods.
