2011-04-29cdrom: always check_disk_change() on openTejun Heo
cdrom_open() called check_disk_change() after the rest of open path succeeded which leads to the following bizarre behavior. * After media change, if the device opened without O_NONBLOCK, open_for_data() naturally fails with -ENOMEDIA and check_disk_change() is never called. The media is known to be gone and the open failure makes it obvious to the userland but device invalidation never happens. * But if the device is opened with O_NONBLOCK, all the checks are bypassed and cdrom_open() doesn't notice that the media is not there and check_disk_change() is called and invalidation happens. There's nothing to be gained by avoiding calling check_disk_change() on open failure. Common cases end up calling check_disk_change() anyway. All we get is inconsistent behavior. Fix it by moving check_disk_change() invocation to the top of cdrom_open() so that it always gets called regardless of how the rest of open proceeds.

2011-02-09cdrom: support devices that have check_events but not media_changedSimon Arlott
Commit 93aae17af1172c40c6f74b7294e93a90c3cfaa5d ("sr: implement sr_check_events()") replaced the media_changed op with the check_events op in drivers/scsi/sr.c All users that check for the CDC_MEDIA_CHANGED capbility try both the check_events op and the media_changed op, but register_cdrom() was requiring media_changed. This patch fixes the capability checking. The cdrom_select_disc ioctl is also using the two operations, so they should be required for CDC_SELECT_DISC too.

2010-12-16cdrom: add ->check_events() supportTejun Heo
In principle, cdrom just needs to pass through ->check_events() but CDROM_MEDIA_CHANGED ioctl makes things a bit more complex. Just as with ->media_changed() support, cdrom code needs to buffer the events and serve them to ioctl and vfs as requested. As the code has to deal with both ->check_events() and ->media_changed(), and vfs and ioctl event buffering, this patch adds check_events caching on top of the existing cdi->mc_flags buffering. It may be a good idea to deprecate CDROM_MEDIA_CHANGED ioctl and remove all this mess. Signed-off-by: Tejun Heo <tj@kernel.org> Signed-off-by: Jens Axboe <jaxboe@fusionio.com>

2008-08-18cdrom: handle TOCAlexander Inyukhin
This patch should fix TOC handling for cdroms that can not play audio. It extends commit af744e3294d09d706c4eae26cffaaa68a8d40337 ("cdrom: don't check CDC_PLAY_AUDIO in cdrom_count_tracks()") with a safety check and non-audio ioctls support. Since CDC_PLAY_AUDIO flag was used not only to check ability to play audio but also to ensure that audio_ioctl was not NULL, all TOC-related operations had to use it. As far as I understand, now audio_ioctl is never NULL, so a sanity check during device registration should be sufficient. It was tested on Optiarc AD7203A device, that has no ability to play audio.

2008-07-04cdrom: revert commit 22a9189 (cdrom: use kmalloced buffers instead of ↵FUJITA Tomonori
buffers on stack) The commit 22a9189fd073db3d03a4cf8b8c098aa207602de1 (cdrom: use kmalloced buffers instead of buffers on stack) is introduced to use kmalloced buffers for packet commands to avoid stack corruption on non coherent platforms. SCSI cdrom uses blk_rq_map_kern, which properly avoids DMA on the stack by using the bounce buffers. IDE cdrom also has the mechnism to avoids DMA on the stack. So we don't need this extra complexitiy in cdrom.c, such as allocating just 8 bytes. The lower layers can handle it.

2007-02-14[PATCH] sysctl: remove insert_at_head from register_sysctlEric W. Biederman
The semantic effect of insert_at_head is that it would allow new registered sysctl entries to override existing sysctl entries of the same name. Which is pain for caching and the proc interface never implemented. I have done an audit and discovered that none of the current users of register_sysctl care as (excpet for directories) they do not register duplicate sysctl entries.

2007-02-14[PATCH] sysctl: cdrom: don't set de->ownerEric W. Biederman
There is no need for open files in /proc/sys/XXX to hold a reference count on the module that provides the file to prevent module unload races. While there is code active in the module p->used in the sysctl_table_header is incremented, preventing the sysctl from being unregisted. Once the sysctl is unregistered it cannot be found. Open files are also not a problem as they revalidate the sysctl information and bump p->used before accessing module code. So setting de->owner is unnecessary, makes for a bad example and gets in my way of removing ctl_table->de. Signed-off-by: Eric W.

2007-01-03[PATCH] cdrom: set default timeout to 7 secondsJens Axboe
It's a known fact that Windows times out commands after 7 seconds, so drives generally try and respond if they can before that happens. We default to 5 seconds, which sometimes is a bit too short. Jeremy Higdon reported here: http://lkml.org/lkml/2007/1/1/145 that his drive takes longer than 5 seconds for a "read track information" command, later confirming that it is about 6.7 seconds.

2006-09-30[PATCH] Split struct request ->flags into two partsJens Axboe
Right now ->flags is a bit of a mess: some are request types, and others are just modifiers. Clean this up by splitting it into ->cmd_type and ->cmd_flags. This allows introduction of generic Linux block message types, useful for sending generic Linux commands to block devices. Signed-off-by: Jens Axboe <axboe@suse.de>
