753b7ae [CPUFREQ] Add p4-clockmod sysfs-ui removal to feature-removal schedule. Signed-off-by: Matthew Garrett <mjg@redhat.com> Signed-off-by: Dave Jones <davej@redhat.com> 09 March 2009, 19:14:37 UTC
129f8ae Revert "[CPUFREQ] Disable sysfs ui for p4-clockmod." This reverts commit e088e4c9cdb618675874becb91b2fd581ee707e6. Removing the sysfs interface for p4-clockmod was flagged as a regression in bug 12826. Course of action: - Find out the remaining causes of overheating, and fix them if possible. ACPI should be doing the right thing automatically. If it isn't, we need to fix that. - mark p4-clockmod ui as deprecated - try again with the removal in six months. It's not really feasible to printk about the deprecation, because it needs to happen at all the sysfs entry points, which means adding a lot of strcmp("p4-clockmod".. calls to the core, which.. bleuch.

082a4cf i2c: Make sure i2c_algo_bit_data.timeout is HZ-independent i2c_algo_bit_data.timeout is supposed to be in jiffies, so drivers should use set this value in terms of HZ.

cd97f39 i2c-dev: Clarify the unit of ioctl I2C_TIMEOUT The unit in which user-space can set the bus timeout value is jiffies for historical reasons (back when HZ was always 100.) This is however not good because user-space doesn't know how long a jiffy lasts. The timeout value should instead be set in a fixed time unit. Given the original value of HZ, this unit should be 10 ms, for compatibility.

e73bf9f firedtv: dvb_frontend_info for FireDTV S2, fix "frequency limits undefined" error I found that the function fdtv_frontend_init in the file firedtv-fe.c was missing a case for FIREDTV_DVB_S2 which resulted in "frequency limits undefined" errors in syslog. Signed-off-by: Beat Michel Liechti <bml303@gmail.com> 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.

1549079 firedtv: massive refactoring Combination of the following changes: Mon, 23 Feb 2009 14:21:10 +0100 (CET) firedtv: reinstate debug logging option Henrik Kurelid tells me that FCP debug logging (which I removed during cleanups) is still useful when working on driver issues together with end users. 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 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.

8ae83cd firedtv: cleanups and minor fixes Combination of the following changes: Sun, 2 Nov 2008 13:45:00 +0100 (CET) firedtv: increase FCP frame length for DVB-S2 tune QSPK The last three bytes didn't go out to the wire. 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 <asm/byteorder.h> instead of <linux/byteorder.h> 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.

9c939e4 ieee1394: inherit ud vendor_id from node vendor_id While Module_Vendor_ID in the configuration ROM's root directory is mandatory, there often aren't vendor IDs in unit directories. 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. Signed-off-by: Stefan Richter <stefanr@s5r6.in-berlin.de> 24 February 2009, 13:51:27 UTC
b33fdd6 ieee1394: add hpsb_node_read() and hpsb_node_lock() These will be used by the firedtv driver. Like hpsb_node_write() they are much better APIs for high-level drivers than hpsb_write() and its siblings --- easier to use correctly and also terser. Unlike hspb_node_write(), the two new functions will only be used by one call site. Hence make them static inline instead of exported symbols.

29f8ea8 ieee1394: use correct barrier types between accesses of nodeid and generation A compiler barrier (explicit on the read side, implicit on the write side) is not quite enough for what has to be accomplished here. 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.)

612262a firesat: copyrights, rename to firedtv, API conversions, fix remote control input Combination of the following changes: Tue, 26 Aug 2008 00:17:30 +0200 (CEST) firedtv: fix remote control input and update the scancode-to-keycode mapping to a current model. 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.

df4846c firesat: update isochronous interface, add CI support I have finally managed to get the CI support for the card working. 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 <henrik@kurelid.se> Signed-off-by: Stefan Richter <stefanr@s5r6.in-berlin.de> (rebased, whitespace) 24 February 2009, 13:51:26 UTC

efbeed9 drm/i915: Don't let a device flush to prepare buffers clear new write_domains. 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.

09c50b4 selinux: Fix the NetLabel glue code for setsockopt() At some point we (okay, I) managed to break the ability for users to use the setsockopt() syscall to set IPv4 options when NetLabel was not active on the socket in question. 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. Please note that we still deny users the ability to override IPv4 options on socket's which have NetLabel labeling active; this is done to ensure the labeling remains intact.

4898c2b fujitsu-laptop: Use RFKILL support bitmask from firmware Up until now, we polled the rfkill status for every incoming FUJ02E3 ACPI event. 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.

403f307 PM: Fix suspend_console and resume_console to use only one semaphore This fixes a race where a thread acquires the console while the console is suspended, and the console is resumed before this thread releases it. 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.

a1bb7d6 PM/hibernate: fix "swap breaks after hibernation failures" http://bugzilla.kernel.org/show_bug.cgi?id=12239 The image writing code dropped a reference to the current swap device. 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().

05bf9e8 ext4: Add fallback for find_group_flex This is a workaround for find_group_flex() which badly needs to be replaced. 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. Signed-off-by: "Theodore Ts'o" <tytso@mit.edu> 21 February 2009, 17:13:24 UTC

eca6acf [CIFS] Fix multiuser mounts so server does not invalidate earlier security contexts When two different users mount the same Windows 2003 Server share using CIFS, the first session mounted can be invalidated. 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 <sfrench@us.ibm.com> 21 February 2009, 03:37:10 UTC
c3b2a0c [CIFS] improve posix semantics of file create Samba server added support for a new posix open/create/mkdir operation a year or so ago, and we added support to cifs for mkdir to use it, but had not added the corresponding code to file create. 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.

b6adea3 8250: fix boot hang with serial console when using with Serial Over Lan port Intel 8257x Ethernet boards have a feature called Serial Over Lan. 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.
