See the statement marked with the label A. The statement B replaces the shost->transportt point with a local struct variable. static struct iscsi_cls_session * iscsi_tcp_session_create(struct iscsi_endpoint *ep, uint16_t cmds_max, uint16_t qdepth, uint32_t initial_cmdsn, uint32_t *hostno) { struct iscsi_cls_session *cls_session; struct iscsi_session *session; struct Scsi_Host *shost; int cmd_i; if (ep) { printk(KERN_ERR "iscsi_tcp: invalid ep %p.\n", ep); return NULL; } A shost = iscsi_host_alloc(&iscsi_sht, 0, qdepth); if (!shost) return NULL; B shost->transportt = iscsi_tcp_scsi_transport; shost->max_lun = iscsi_max_lun; Please note the scsi host is allocated by invoking isccsi_host_alloc() in libiscsi.c Polluting the middle level blank_transport_template in iscsi_host_alloc() of libiscsi.c The iscsi_host_alloc() invokes the middle level function scsi_host_alloc() in hosts.c for allocating a scsi_host. Then the statement marked with C assigns the iscsi_eh_cmd_timed_out handler to the eh_timed_out callback function. struct Scsi_Host *iscsi_host_alloc(struct scsi_host_template *sht, int dd_data_size, uint16_t qdepth) { struct Scsi_Host *shost; struct iscsi_host *ihost; shost = scsi_host_alloc(sht, sizeof(struct iscsi_host) + dd_data_size); if (!shost) return NULL; C shost->transportt->eh_timed_out = iscsi_eh_cmd_timed_out; Please note the shost->transport is the middle level blank_transport_template as shown in the code segment below. We see two problems here. 1. iscsi_eh_cmd_timed_out is installed to the blank_transport_template that will cause some body else problem. 2. iscsi_eh_cmd_timed_out will never be invoked when iscsi command gets timeout because the statement B resets the pointer. Middle level blank_transport_template In the middle level function scsi_host_alloc() of hosts.c, the middle level assigns a blank_transport_template for those hosts not implementing its transport layer. All HBAs without supporting a specific scsi_transport will share the middle level blank_transport_template. Please see the statement D struct Scsi_Host *scsi_host_alloc(struct scsi_host_template *sht, int privsize) { struct Scsi_Host *shost; gfp_t gfp_mask = GFP_KERNEL; int rval; if (sht->unchecked_isa_dma && privsize) gfp_mask |= __GFP_DMA; shost = kzalloc(sizeof(struct Scsi_Host) + privsize, gfp_mask); if (!shost) return NULL; shost->host_lock = &shost->default_lock; spin_lock_init(shost->host_lock); shost->shost_state = SHOST_CREATED; INIT_LIST_HEAD(&shost->__devices); INIT_LIST_HEAD(&shost->__targets); INIT_LIST_HEAD(&shost->eh_cmd_q); INIT_LIST_HEAD(&shost->starved_list); init_waitqueue_head(&shost->host_wait); mutex_init(&shost->scan_mutex); shost->host_no = scsi_host_next_hn++; /* XXX(hch): still racy */ shost->dma_channel = 0xff; /* These three are default values which can be overridden */ shost->max_channel = 0; shost->max_id = 8; shost->max_lun = 8; /* Give each shost a default transportt */ D shost->transportt = &blank_transport_template; Why we see panic at iscsi_eh_cmd_timed_out() The mpp virtual HBA doesn’t have a specific scsi_transport. Therefore, the blank_transport_template will be assigned to the virtual host of the MPP virtual HBA by SCSI middle level. Please note that the statement C has assigned iscsi-transport eh_timedout handler to the blank_transport_template. When a mpp virtual command gets timedout, the iscsi_eh_cmd_timed_out() will be invoked to handle mpp virtual command timeout from the middle level scsi_times_out() function of the scsi_error.c. enum blk_eh_timer_return scsi_times_out(struct request *req) { struct scsi_cmnd *scmd = req->special; enum blk_eh_timer_return (*eh_timed_out)(struct scsi_cmnd *); enum blk_eh_timer_return rtn = BLK_EH_NOT_HANDLED; scsi_log_completion(scmd, TIMEOUT_ERROR); if (scmd->device->host->transportt->eh_timed_out) E eh_timed_out = scmd->device->host->transportt->eh_timed_out; else if (scmd->device->host->hostt->eh_timed_out) eh_timed_out = scmd->device->host->hostt->eh_timed_out; else eh_timed_out = NULL; if (eh_timed_out) { rtn = eh_timed_out(scmd); It is very easy to understand why we get panic in the iscsi_eh_cmd_timed_out(). A scsi_cmnd from a no-iscsi device definitely can not resolve out a session and session->lock. The panic can be happed anywhere during the differencing. static enum blk_eh_timer_return iscsi_eh_cmd_timed_out(struct scsi_cmnd *scmd) { struct iscsi_cls_session *cls_session; struct iscsi_session *session; struct iscsi_conn *conn; enum blk_eh_timer_return rc = BLK_EH_NOT_HANDLED; cls_session = starget_to_session(scsi_target(scmd->device)); session = cls_session->dd_data; debug_scsi("scsi cmd %p timedout\n", scmd); spin_lock(&session->lock); This patch fixes the problem by moving the setting of the iscsi_eh_cmd_timed_out to iscsi_add_host, which is after the LLDs have set their transport template to shost->transportt.

To ensure smooth operations amongst the FCoE and NIC side components of the ISP81xx chip, the FCoE driver (qla2xxx) must ensure the 10gb NIC driver (qlge) does not timeout waiting for IDC (Inter-Driver Communication) acknowledgments. The acknowledgment requirements are trivial -- a simple mirroring of incoming mailbox registers during the AEN to a process-context capable mailbox command.

Apparently the forcedeth situation is rather messy in that the mac we need to writeback for a subsequent modprobe to work is exactly the reverse of what is needed for proper wake-on-lan. The following patch explains the situation in the comments and makes the call to nv_restore_mac_addr() conditional (only called if we are not really going for poweroff).

A long time ago we had bugs, primarily in TCP, where we would modify skb->truesize (for TSO queue collapsing) in ways which would corrupt the socket memory accounting. skb_truesize_check() was added in order to try and catch this error more systematically. However this debugging check has morphed into a Frankenstein of sorts and these days it does nothing other than catch false-positives. Signed-off-by: David S.

So the timer is dequeued, the stats are read and then the timer is enqueued again. This is "okay" unless someone unloads the module. The locking here is also broken: mib_counters_update() grabs just a simple spinlock. The only thing the lock is good for is to protect the timer func against other callers namely mv643xx_eth_stop() && mv643xx_eth_get_ethtool_stats(). That means if the spinlock is taken via the ethtool path and than the timer kicks in then the box will lock up.

Commit e7b14036 removes the targetted disabled CPU from the cpu_online_map after calls to migrate_platform_irqs and fixup_irqs. Paul McKenney states that the reasoning behind the patch was to prevent irq handlers from running on CPUs marked offline because: RCU happily ignores CPUs that don't have their bits set in cpu_online_map, so if there are RCU read-side critical sections in the irq handlers being run, RCU will ignore them. If the other CPUs were running, they might sequence through the RCU state machine, which could result in data structures being yanked out from under those irq handlers, which in turn could result in oopses or worse. Unfortunately, both ia64 functions above look at cpu_online_map to find a new CPU to migrate interrupts onto. This means we can potentially migrate an interrupt off ourself back to... ourself. Uh oh. This causes an oops when we finally try to process pending interrupts on the CPU we want to disable. The oops results from calling __do_IRQ with a NULL pt_regs: Unable to handle kernel NULL pointer dereference (address 0000000000000040) Call Trace: [] show_stack+0x50/0xa0 sp=e0000009c922fa00 bsp=e0000009c92214d0 [] show_regs+0x820/0x860 sp=e0000009c922fbd0 bsp=e0000009c9221478 [] die+0x1a0/0x2e0 sp=e0000009c922fbd0 bsp=e0000009c9221438 [] ia64_do_page_fault+0x950/0xa80 sp=e0000009c922fbd0 bsp=e0000009c92213d8 [] ia64_native_leave_kernel+0x0/0x270 sp=e0000009c922fc60 bsp=e0000009c92213d8 [] profile_tick+0xd0/0x1c0 sp=e0000009c922fe30 bsp=e0000009c9221398 [] timer_interrupt+0x170/0x3e0 sp=e0000009c922fe30 bsp=e0000009c9221330 [] handle_IRQ_event+0x80/0x120 sp=e0000009c922fe30 bsp=e0000009c92212f8 [] __do_IRQ+0x160/0x4a0 sp=e0000009c922fe30 bsp=e0000009c9221290 [] ia64_process_pending_intr+0x2b0/0x360 sp=e0000009c922fe30 bsp=e0000009c9221208 [] fixup_irqs+0xf0/0x2a0 sp=e0000009c922fe30 bsp=e0000009c92211a8 [] __cpu_disable+0x140/0x240 sp=e0000009c922fe30 bsp=e0000009c9221168 [] take_cpu_down+0x50/0xa0 sp=e0000009c922fe30 bsp=e0000009c9221148 [] stop_cpu+0xd0/0x200 sp=e0000009c922fe30 bsp=e0000009c92210f0 [] kthread+0xc0/0x140 sp=e0000009c922fe30 bsp=e0000009c92210c8 [] kernel_thread_helper+0xd0/0x100 sp=e0000009c922fe30 bsp=e0000009c92210a0 [] start_kernel_thread+0x20/0x40 sp=e0000009c922fe30 bsp=e0000009c92210a0 I don't like this revert because it is fragile. ia64 is getting lucky because we seem to only ever process timer interrupts in this path, but if we ever race with an IPI here, we definitely use RCU and have the potential of hitting an oops that Paul describes above. Patching ia64's timer_interrupt() to check for NULL pt_regs is insufficient though, as we still hit the above oops. As a short term solution, I do think that this revert is the right answer. The revert hold up under repeated testing (24+ hour test runs) with this setup: - 8-way rx6600 - randomly toggling CPU online/offline state every 2 seconds - running CPU exercisers, memory hog, disk exercisers, and network stressors - average system load around ~160 In the long term, we really need to figure out why we set pt_regs = NULL in ia64_process_pending_intr(). If it turns out that it is unnecessary to do so, then we could safely re-introduce e7b14036 (along with some other logic to be smarter about migrating interrupts). One final note: x86 also removes the disabled CPU from cpu_online_map and then re-enables interrupts for 1ms, presumably to handle any pending interrupts: arch/x86/kernel/irq_32.c (and irq_64.c): cpu_disable_common: [remove cpu from cpu_online_map] fixup_irqs(): for_each_irq: [break CPU affinities] local_irq_enable(); mdelay(1); local_irq_disable(); So they are doing implicitly what ia64 is doing explicitly.

So this is a potential AB-BA deadlock. The way that i915_gem_execbuffer() triggers a page fault is by doing copy_to_user() when returning new buffer offsets back to userspace; however there is no reason to hold the struct_mutex when doing this copy, since what is being copied is the contents of an array private to i915_gem_execbuffer() anyway. So we can fix the potential deadlock (and get rid of the lockdep warning) by simply moving the copy_to_user() outside of where struct_mutex is held. This fixes .

In the case where no EDID data is read from the device, adding the panel_fixed_mode pointer to the probed modes list causes data corruption. If the panel_fixed_mode pointer is added to the probed modes list at init time, a copy of the mode is added again at drm_get_modes() request time. Then, the panel_fixed_mode pointer is freed because it is seen as a duplicate mode. Unfortunately, this pointer is still stored and used in mode_fixup(). Because the panel_fixed_mode data is copied and returned at drm_get_modes() time, it is unnecessary to add this information at init time.

The v1.4 version of the firmware has been submitted to David Woodhouse for inclusion in the linux-firmware tree and it is already available at http://linuxwimax.org/Download. The reason for this change is that the 1.3 release of the user space software and firmware has a few issues that will make it difficult to use with currently deployed commercial networks such as Xohm and Clearwire. As well, the new 1.4 release of the user space software (which matches the 1.4 firmware) has intermitent issues with the 1.3 firmware. The 1.4 release in http://linuxwimax.org/Download has been widely deployed and tested with the codebase in 2.6.29-rc, the 1.4 firmware and the 1.4 user space components.

This feature works by emulating a serial port, and it is detected by kernel as a normal 8250 port. However, this emulation is not perfect, as also noticed on changeset 7500b1f602aad75901774a67a687ee985d85893f. Before this patch, the kernel were trying to check if the serial TX is capable of work using IRQ's. This were done with a code similar this: serial_outp(up, UART_IER, UART_IER_THRI); lsr = serial_in(up, UART_LSR); iir = serial_in(up, UART_IIR); serial_outp(up, UART_IER, 0); if (lsr & UART_LSR_TEMT && iir & UART_IIR_NO_INT) up->bugs |= UART_BUG_TXEN; This works fine for other 8250 ports, but, on 8250-emulated SoL port, the chip is a little lazy to down UART_IIR_NO_INT at UART_IIR register. Due to that, UART_BUG_TXEN is sometimes enabled. However, as TX IRQ keeps working, and the TX polling is now enabled, the driver miss-interprets the IRQ received later, hanging up the machine until a key is pressed at the serial console. This is the 6 version of this patch. Previous versions were trying to introduce a large enough delay between serial_outp and serial_in(up, UART_IIR), but not taking forever. However, the needed delay couldn't be safely determined. At the experimental tests, a delay of 1us solves most of the cases, but still hangs sometimes. Increasing the delay to 5us was better, but still doesn't solve. A very high delay of 50 ms seemed to work every time. However, poking around with delays and pray for it to be enough doesn't seem to be a good approach, even for a quirk. So, instead of playing with random large arbitrary delays, let's just disable UART_BUG_TXEN for all SoL ports.

The following patch helps improve the performance of the cifs create path (to Samba and servers which support the cifs posix protocol extensions). Using Connectathon basic test1, with 2000 files, the performance improved about 15%, and also helped reduce network traffic (17% fewer SMBs sent over the wire) due to saving a network round trip for the SetPathInfo on every file create. It should also help the semantics (and probably the performance) of write (e.g. when posix byte range locks are on the file) on file handles opened with posix create, and adds support for a few flags which would have to be ignored otherwise.

Some servers invalidate the first smb session when a second similar user (e.g. two users who get mapped by server to "guest") authenticates an smb session from the same client. By making sure that we set the 2nd and subsequent vc numbers to nonzero values, this ensures that we will not have this problem. Fixes Samba bug 6004, problem description follows: How to reproduce: - configure an "open share" (full permissions to Guest user) on Windows 2003 Server (I couldn't reproduce the problem with Samba server or Windows older than 2003) - mount the share twice with different users who will be authenticated as guest. noacl,noperm,user=john,dir_mode=0700,domain=DOMAIN,rw noacl,noperm,user=jeff,dir_mode=0700,domain=DOMAIN,rw Result: - just the mount point mounted last is accessible: Signed-off-by: Steve French --- fs/cifs/CHANGES | 10 ++++++ fs/cifs/cifsfs.h | 2 +- fs/cifs/cifsglob.h | 6 +++- fs/cifs/cifssmb.c | 7 ++-- fs/cifs/sess.c | 87 ++++++++++++++++++++++++++++++++++++++++++++-- 5 files changed, 105 insertions(+), 7 deletions(-) diff --git a/fs/cifs/CHANGES b/fs/cifs/CHANGES index 72063f5e56b1..851388fafc73 100644 --- a/fs/cifs/CHANGES +++ b/fs/cifs/CHANGES @@ -1,3 +1,13 @@ +Version 1.57 +------------ +Improve support for multiple security contexts to the same server.

However, this function (and its successors) was flagged __cpuinit, which becomes __init on UP configurations (on SMP suspend/resume requires CPU hotplug and so this would not be seen.)

One of its problems (besides ignoring the Orlov algorithm) is that it is a bit hyperactive about returning failure under suspicious circumstances. This can lead to spurious ENOSPC failures even when there are inodes still available. Work around this for now by retrying the search using find_group_other() if find_group_flex() returns -1. If find_group_other() succeeds when find_group_flex() has failed, log a warning message. A better block/inode allocator that will fix this problem for real has been queued up for the next merge window.

This doesn't show up if the hibernation succeeds - because it doesn't affect the image which gets resumed. But it means multiple _failed_ hibernations end up freeing the swap device while it is still use! swsusp_write() finds the block device for the swap file using swap_type_of(). It then uses blkdev_get() / blkdev_put() to open and close the block device. Unfortunately, blkdev_get() assumes ownership of the inode of the block_device passed to it. So blkdev_put() calls iput() on the inode. This is by design and other callers expect this behaviour. The fix is for swap_type_of() to take a reference on the inode using bdget().

In this case, the secondary console semaphore would be left locked, and the primary semaphore would be released twice. This in turn would cause the console switch on suspend or resume to hang forever. Note that suspend_console does not actually lock the console for clients that use acquire_console_sem, it only locks it for clients that use try_acquire_console_sem. If we change suspend_console to fully lock the console, then the kernel may deadlock on suspend. One client of try_acquire_console_sem is acquire_console_semaphore_for_printk, which uses it to prevent printk from using the console while it is suspended.

It turns out that the firmware has a bitmask which indicates what rfkill-related state it can report. The rfkill_supported bitmask is now used to avoid polling for rfkill at all in the notification handler if there is no support. Also, it is used in the platform device callbacks. As before we register all callbacks and report "unknown" if the firmware does not give us status updates for that particular bit. This was fed through checkpatch.pl and tested on the S6420, S7020 and P8010 platforms.

The problem was noticed by someone trying to use the "-R" (record route) option of ping: # ping -R 10.0.0.1 ping: record route: No message of desired type The solution is relatively simple, we catch the unlabeled socket case and clear the error code, allowing the operation to succeed.

The problem was that object_set_to_gpu_domain would set the new write_domains that are getting set by this batchbuffer, then the accumulated flushes required for all the objects in preparation for this batchbuffer were posted, and the brand new write domain would get cleared by the flush being posted. Instead, hang on to the new (or old if we're not changing it) value and set it after the flush is queued. Results from this noticably included conformance test failures from reads shortly after writes (where the new write domain had been lost and thus not flushed and waited on), but is a suspected cause of hangs in some apps when a write domain is lost on a buffer that gets reused for instruction or commmand state.

From f1bbb43a667067f24a729df78dc050348b1c7846 Mon Sep 17 00:00:00 2001 From: Ben Backx Date: Sun, 22 Jun 2008 16:00:53 +0200 Subject: [PATCH 135/160] firesat: fix DVB-S2 device recognition This only makes sure that a DVB-S2 device is really recognized as a S2, nothing else is added yet. It's using the string containing the model that is stored in the configuration ROM, the older version was using some hardware revision dependent part of the ROM.

The implementation is a bare minimum to get encrypted channels to work in kaffeine. It works fine with my T/CI card. Now and then I get an AVC timeout and have to retune a channel in order to get it to work. Once the CAM seemed to hang so I needed to remove and insert it again. I.e. there are a number of glitches. The latest version contains the following changes: - Implemented the new hpsb iso interface so that data can be received from the card - Reduced some timers for demux setup which caused scanning to timeout - Added possibility to unload driver - Added support for getting C/N ratio - Added two debug parameters to the driver; ca_debug and avc_comm_debug. - Added CI support that works for me in kaffeine - Started working on CI MMI support. It now supports: o Enter menu o Receiving MMI objects - Added support for 64-bit platforms - Corrected DVB-C modulations problems Signed-off-by: Henrik Kurelid Signed-off-by: Stefan Richter (rebased, whitespace) --- drivers/media/dvb/firesat/Makefile | 1 + drivers/media/dvb/firesat/avc_api.c | 770 ++++++++++++++++++----- drivers/media/dvb/firesat/avc_api.h | 296 +++++---- drivers/media/dvb/firesat/cmp.c | 40 +- drivers/media/dvb/firesat/firesat-ci.c | 342 ++++++++-- drivers/media/dvb/firesat/firesat.h | 174 ++++- drivers/media/dvb/firesat/firesat_1394.c | 123 +--- drivers/media/dvb/firesat/firesat_dvb.c | 49 +- drivers/media/dvb/firesat/firesat_fe.c | 80 ++- drivers/media/dvb/firesat/firesat_iso.c | 106 ++++ 10 files changed, 1487 insertions(+), 494 deletions(-) create mode 100644 drivers/media/dvb/firesat/firesat_iso.c diff --git a/drivers/media/dvb/firesat/Makefile b/drivers/media/dvb/firesat/Makefile index fdf86870f1fd..be7701b817c9 100644 --- a/drivers/media/dvb/firesat/Makefile +++ b/drivers/media/dvb/firesat/Makefile @@ -1,6 +1,7 @@ firesat-objs := firesat_1394.o \ firesat_dvb.o \ firesat_fe.o \ + firesat_iso.o \ avc_api.o \ cmp.o \ firesat-rc.o \ diff --git a/drivers/media/dvb/firesat/avc_api.c b/drivers/media/dvb/firesat/avc_api.c index cd79c806ecc7..273c7235dd90 100644 --- a/drivers/media/dvb/firesat/avc_api.c +++ b/drivers/media/dvb/firesat/avc_api.c @@ -3,6 +3,7 @@ * * Copyright (c) 2004 Andreas Monitzer * Copyright (c) 2008 Ben Backx + * Copyright (c) 2008 Henrik Kurelid * * This program is free software;

Per default, various media key keycodes are emitted which closely match what is printed on the remote. Userland can modify the mapping by means of evdev ioctls. (Not tested.) The old scancode-to-keycode mapping is left in the driver but cannot be modified by ioctls. This preserves status quo for old remotes. Tue, 26 Aug 2008 00:11:28 +0200 (CEST) firedtv: replace tasklet by workqueue job Non-atomic context is a lot nicer to work with. Sun, 24 Aug 2008 23:30:00 +0200 (CEST) firedtv: move some code back to ieee1394 core Partially reverts "ieee1394: remove unused code" of Linux 2.6.25. Sun, 24 Aug 2008 23:29:30 +0200 (CEST) firedtv: replace semaphore by mutex firesat->avc_sem and ->demux_sem have been used exactly like a mutex. The only exception is the schedule_remotecontrol tasklet which did a down_trylock in atomic context. This is not possible with mutex_trylock; however the whole remote control related code is non-functional anyway at the moment. This should be fixed eventually, probably by turning the tasklet into a worqueue job. Convert everything else from semaphore to mutex. Also rewrite a few of the affected functions to unlock the mutex at a single exit point, instead of in several branches. Sun, 24 Aug 2008 23:28:45 +0200 (CEST) firedtv: some header cleanups Unify #ifndef/#define/#endif guards against multiple inclusion. Drop extern keyword from function declarations. Remove #include's into header files where struct declarations suffice. Remove unused ohci1394 interface and related unused ieee1394 interfaces. Add a few missing #include's and remove a few apparently obsolete ones. Sort them alphabetically. Sun, 24 Aug 2008 23:27:45 +0200 (CEST) firedtv: nicer registration message and some initialization fixes Print the correct name in dvb_register_adapter(). While we are at it, replace two switch cascades by one for loop, remove a superfluous member of struct firesat and of two unused arguments of AVCIdentifySubunit(), and fix bogus kfree's in firesat_dvbdev_init(). Tue, 26 Aug 2008 14:24:17 +0200 (CEST) firesat: rename to firedtv Suggested by Andreas Monitzer. Besides DVB-S/-S2 receivers, the driver also supports DVB-C and DVB-T receivers, hence the previous project name is too narrow now. Not yet done: Rename source directory, files, types, variables... Sun, 24 Aug 2008 23:26:23 +0200 (CEST) firesat: add missing copyright notes Reported by Andreas Monitzer and Christian Dolzer.

Use hardware memory barriers on systems which need them. (Of course a full fix of generation handling would require much more than this. The ieee1394 core's bus generation counter had to be tied to the controller's bus generation counter; cf. Kristian's stack. It's just that I have other current business with the code around these barrier()s, so why not do at least this small fix.)

This affects the new firedtv driver which is meant to be auto-loaded and matched only for vendor-specific devices. We now always copy ne->vendor_id into ud->vendor_id before we scan a unit directory (and fill in a possibly present vendor ID from there). This way, the root directory's vendor ID is used as fallback in the "uevent" environment for modprobe'ing per module alias when a node was plugged in, and in the driver match routine when protocol drivers are bound to unit directories. It will however not be used as sysfs attribute of a unit directory device.

Effect of the fix not yet tested. Sun, 2 Nov 2008 13:45:00 +0100 (CET) firedtv: replace mdelay by msleep These functions can sleep (and in fact sleep for the duration of a whole FCP transaction). Hence msleep is more appropriate here. Sun, 2 Nov 2008 13:45:00 +0100 (CET) firedtv: trivial reorganization in avc_api Reduce nesting level by factoring code out of avc_tuner_dsd() into helper functions. Sun, 2 Nov 2008 13:45:00 +0100 (CET) firedtv: trivial cleanups in avc_api Use dev_err(), no CamelCase function names, adjust comment style, put #if 0 around unused code and add FIXME comments, standardize on lower-case hexadecimal constants, use ALIGN() for some frame length calculations, make a local function static... The code which writes FCP command frames and reads FCP response frames is not yet brought into canonical kernel coding style because this involves changes of typedefs (on-the-wire bitfields). Sun, 2 Nov 2008 13:45:00 +0100 (CET) firedtv: don't retry oPCR updates endlessly In the theoretical case that the target node wasn't handling the lock transactions as expected or there was continued interference by other initiating nodes, these functions wouldn't return for ages. Sun, 2 Nov 2008 13:45:00 +0100 (CET) firedtv: remove bitfield typedefs from cmp, fix for big endian CPUs Use macros/ inline functions/ standard byte order accessors to read and write oPCR register values (big endian bitfields, on-the-wire data). The new code may not be the ultimate optimum, but it doesn't occur in a hot path. This fixes the CMP code for big endian CPUs. So far I tested it only on a little endian CPU though. For now, include instead of because drivers/ieee1394/*.h also include the former. I will fix this in drivers/ieee1394 and firedtv later. Sun, 2 Nov 2008 13:45:00 +0100 (CET) firedtv: trivial cleanups in cmp Reduce nesting level by means of early exit and goto. Remove obsolete includes, use dev_err(), no CamelCase function names... Sun, 2 Nov 2008 13:45:00 +0100 (CET) firedtv: trivial cleanups in firesat-ci Whitespace, variable names, comment style... Also, use dvb_generic_open() and dvb_generic_release() directly as our hooks in struct file_operations because firedtv's wrappers merely called these generic functions. Sun, 2 Nov 2008 13:45:00 +0100 (CET) firedtv: remove CA debug code This looks like it is not necessary to have available for endusers who cannot patch kernels for bug reporting and tests of fixes. Sun, 2 Nov 2008 13:45:00 +0100 (CET) firedtv: remove AV/C debug code This looks like it is not necessary to have available for endusers who cannot patch kernels for bug reporting and tests of fixes. Sun, 2 Nov 2008 13:45:00 +0100 (CET) firedtv: remove various debug code Most of this was already commented out. And that which wasn't is not relevant in normal use. Mon, 29 Sep 2008 19:22:48 +0200 (CEST) firedtv: register input device as child of a FireWire device Instead of one virtual input device which exists for the whole lifetime of the driver and receives events from all connected FireDTVs, register one input device for each firedtv device. These input devices will show up as children of the respective firedtv devices in the sysfs hierarchy. However, the implementation falls short because of a bug in userspace: Udev's path_id script gets stuck with 100% CPU utilization, maybe because of an assumption about the maximum ieee1394 device hierarchy depth. To avoid this bug, we use the fw-host device instead of the proper unit_directory device as parent of the input device. There is hope that the port to the new firewire stack won't be inhibited by this userspace bug because there are no fw-host devices there. Mon, 29 Sep 2008 19:21:52 +0200 (CEST) firedtv: fix string comparison and a few sparse warnings Sparse found a bug: while ((kv_buf + kv_len - 1) == '\0') should have been while (kv_buf[kv_len - 1] == '\0') We fix it by a better implementation without a temporary copy. Also fix sparse warnings of 0 instead of NULL and signedness mismatches. Mon, 29 Sep 2008 19:21:20 +0200 (CEST) firedtv: remove unused struct members and redefine an int as a bool. Mon, 29 Sep 2008 19:20:36 +0200 (CEST) firedtv: fix initialization of dvb_frontend.ops There was a NULL pointer reference if no dvb_frontend_info was found. Also, don't directly assign struct typed values to struct typed variables. Instead write out assignments to individual strcut members. This reduces module size by about 1 kB. Mon, 29 Sep 2008 19:19:41 +0200 (CEST) firedtv: remove unused dual subunit code from initialization No FireDTVs with more than one subunit exists, hence simplify the initialization for the special case of one subunit. The driver was able to check for more than one subunit but was broken for more than two subunits. While we are at it, add several missing cleanups after failure, and include a few dynamically allocated structures diretly into struct firesat instead of allocating them separately. Mon, 29 Sep 2008 19:19:08 +0200 (CEST) firedtv: add vendor_id and version to driver match table Now that nodemgr was enhanced to match against the root directory's vendor ID if there isn't one in the unit directory, use this to prevent firedtv to be bound to wrong devices by accident. Also add the AV/C software version ID to the match flags for completeness; specifier ID and software only make sense as a pair. Mon, 29 Sep 2008 19:18:30 +0200 (CEST) firedtv: use hpsb_node_read(), _write(), _lock() because they are simpler and treat the node generation more correctly. While we are at it, clean up and simplify surrounding code.

So bring it back in an updated form with only 60% of the original code footprint. Logging can be enabled with # echo -1 > /sys/module/firedtv/parameters/debug 1 instead of -1 enables only FCP header logging, 2 instead of -1 enables only hexdumps of the entire FCP frames. 0 switches logging off again. Fri, 20 Feb 2009 20:54:27 +0100 (CET) firedtv: build fix for INPUT=m and DVB_FIREDTV=y Thu, 19 Feb 2009 20:40:39 +0100 firedtv: use msecs_to_jiffies Pointed out by Mauro Carvalho Chehab. Sun Feb 15 20:50:46 CET 2009 firedtv: some more housekeeping Fix an old checkpatch warning and a new compiler warning. Sun Feb 15 15:33:17 CET 2009 firedtv: rename a file once more At the moment, about a third of avc.c is specific to FireDTVs rather than generic AV/C code. Rename it to firedtv-avc.c. Sun Feb 15 15:33:17 CET 2009 firedtv: dvb demux: more compact channels backing store Replace struct firedtv_channel { bool active; int pid; } channel[16]; by unsigned long channel_active; u16 channel_pid[16];. Sun Feb 15 15:33:17 CET 2009 firedtv: dvb demux: some simplifications c->active was unnecessarily cleared twice. Also, by marking the channel inactive before the for loop, the loop becomes identical with fdtv_channel_collect(). Sun Feb 15 15:33:17 CET 2009 firedtv: dvb demux: remove a bogus loop This loop is unnecessary because - only active channel[].pid's will be sent to the device, - when a channel is activated, its pid is set to dvbdmxfeed->pid. Perhaps the original code was there because it was initially not fully covered by the fdtv->demux_mutex. Sun Feb 15 15:33:17 CET 2009 firedtv: dvb demux: fix mutex protection fdtv_start_feed() accessed the channel list unsafely. Fully serialize it with itself and fdtv_stop_feed(). Sun Feb 15 15:33:17 CET 2009 firedtv: dvb demux: fix missing braces Original code was: ... case DMX_TS_PES_OTHER: //Dirty fix to keep firesat->channel pid-list up to date for(k=0;k<16;k++){ if(firesat->channel[k].active == 0) firesat->channel[k].pid = dvbdmxfeed->pid; break; } channel = firesat_channel_allocate(firesat); break; default: ... Looks bogus in several respects. For now let's just add braces to the if because that seems to be what the author meant. Sun Feb 15 15:33:17 CET 2009 firedtv: allow build without input subsystem !CONFIG_INPUT is very unlikely on systems on which firedtv is of interest. But we can easily support it. Sun Feb 15 15:33:17 CET 2009 firedtv: replace EXTRA_CFLAGS by ccflags The former are deprecated. The latter can depend on Kconfig variables. Sun Feb 15 15:33:17 CET 2009 firedtv: concentrate ieee1394 dependencies Move the entire interface with drivers/ieee1394 to firedtv-1394.c. Move 1394-independent module initialization code to firedtv-dvb.c. This prepares interfacing with drivers/firewire. Sun Feb 15 15:33:17 CET 2009 firedtv: amend Kconfig menu prompt Sun Feb 15 15:33:17 CET 2009 firedtv: remove kernel version compatibility macro Sun Feb 15 15:33:17 CET 2009 firedtv: combine header files avc.h and firedtv-*.h are small and currently not shared with other drivers, hence concatenate them all into firedtv.h. Sun Feb 15 15:33:17 CET 2009 firedtv: misc style touch-ups Standardize on lower-case hexadecimal constants. Adjust whitespace. Omit unnecessary pointer type casts and an unnecessary list head initialization. Use dev_printk. Wed Feb 11 21:21:04 CET 2009 firedtv: avc, ci: remove unused constants Wed Feb 11 21:21:04 CET 2009 firedtv: avc: remove bitfields from read descriptor response operands Don't use bitfields in struct types of on-the-wire data. Wed Feb 11 21:21:04 CET 2009 firedtv: avc: remove bitfields from DSD command operands Don't use bitfields in struct types of on-the-wire data. Wed Feb 11 21:21:04 CET 2009 firedtv: avc: header file cleanup Remove unused constants and declarations. Move privately used constants into .c files. Wed Feb 11 21:21:04 CET 2009 firedtv: avc: remove bitfields from FCP frame types Don't use bitfields in struct types of on-the-wire data. Also move many privately used constants from avc.h to avc.c and remove some unused constants. Sun, 18 Jan 2009 16:30:00 +0100 (CET) firedtv: avc: fix offset in avc_tuner_get_ts The parentheses were wrong. It didn't matter though because this code only writes a 0 into an area which is already initialized to 0. Sun, 18 Jan 2009 16:30:00 +0100 (CET) firedtv: avc: reduce stack usage, remove two typedefs It is safe to share a memory buffer for command frame and response frame because the response data come in after the command frame was last used. Even less stack would be required if only the actual required frame size instead of the entire FCP register size was allocated. Also, rename the defined types AVCCmdFrm and AVCRspFrm to struct avc_command_frame and struct avc_response_frame. TODO: Remove the bitfields in these types.

Signed-off-by: Beat Michel Liechti Change by Stefan R: combine it with case case FIREDTV_DVB_S as originally suggested by Beat Michel. This enables FE_CAN_FEC_AUTO also for FireDTV-S2 devices which is possible as long as only DVB-S channels are used. FE_CAN_FEC_AUTO would be wrong for DVB-S2 channels, but those cannot be used yet since the driver is not yet converted to S2API.
