2022-05-15cdrom: remove the unused driver specific disc change ioctlPaul Gortmaker
This was only used by the ide-cd driver, which went away in commit b7fb14d3ac63 ("ide: remove the legacy ide driver") so we might as well take advantage of that and get rid of this hook as well.

2021-09-14drivers/cdrom: improved ioctl for media change detectionLukas Prediger
The current implementation of the CDROM_MEDIA_CHANGED ioctl relies on global state, meaning that only one process can detect a disc change while the ioctl call will return 0 for other calling processes afterwards (see bug 213267). This introduces a new cdrom ioctl, CDROM_TIMED_MEDIA_CHANGE, that works by maintaining a timestamp of the last detected disc change instead of a boolean flag: Processes calling this ioctl command can provide a timestamp of the last disc change known to them and receive an indication whether the disc was changed since then and the updated timestamp. I considered fixing the buggy behavior in the original CDROM_MEDIA_CHANGED ioctl but that would require maintaining state for each calling process in the kernel, which seems like a worse solution than introducing this new ioctl.

2019-07-15docs: add some directories to the main documentation indexMauro Carvalho Chehab
The contents of those directories were orphaned at the documentation body. While those directories could likely be moved to be inside some guide, I'm opting to just adding their indexes to the main one, removing the :orphan: and adding the SPDX header. For the drivers, the rationale is that the documentation contains a mix of Kernelspace, uAPI and admin-guide. So, better to keep them on separate directories, as we've be doing with similar subsystem-specific docs that were not split yet. For the others, well... I'm too lazy to do the move. Also, it seems to make sense to keep at least some of those at the main dir (like kbuild, for example). In any case, a latter patch could do the move.

2019-06-14docs: ide: convert docs to ReST and rename to *.rstMauro Carvalho Chehab
The conversion is actually: - add blank lines and identation in order to identify paragraphs; - fix tables markups; - add some lists markups; - mark literal blocks; - adjust title markups. At its new index.rst, let's add a :orphan: while this is not linked to the main index.rst file, in order to avoid build warnings.

The stuff there is almost already at ReST format. A conversion for them is trivial: just add a missing titles and fix some scape codes for them to match ReST syntax. While here, rename the cdrom-standard.txt, with was converted from LaTeX to ReST on the previous patch, and add it to the index file.

This is the only LaTeX documentation file inside the documentation. Instead of having a Latex document directly there, convert it to ReST format, as this is the format we're using for docs. For now, let's keep the extension as .txt in order to avoid warnings when building the documentation with Sphinx. The next patch patch will rename it to .rst and add it to the building system.

2018-09-09Drop all 00-INDEX files from Documentation/Henrik Austad
This is a respin with a wider audience (all that get_maintainer returned) and I know this spams a *lot* of people. Not sure what would be the correct way, so my apologies for ruining your inbox. The 00-INDEX files are supposed to give a summary of all files present in a directory, but these files are horribly out of date and their usefulness is brought into question. Often a simple "ls" would reveal the same information as the filenames are generally quite descriptive as a short introduction to what the file covers (it should not surprise anyone what Documentation/sched/sched-design-CFS.txt covers) A few years back it was mentioned that these files were no longer really needed, and they have since then grown further out of date, so perhaps it is time to just throw them out. A short status yields the following _outdated_ 00-INDEX files, first counter is files listed in 00-INDEX but missing in the directory, last is files present but not listed in 00-INDEX. List of outdated 00-INDEX: Documentation: (4/10) Documentation/sysctl: (0/1) Documentation/timers: (1/0) Documentation/blockdev: (3/1) Documentation/w1/slaves: (0/1) Documentation/locking: (0/1) Documentation/devicetree: (0/5) Documentation/power: (1/1) Documentation/powerpc: (0/5) Documentation/arm: (1/0) Documentation/x86: (0/9) Documentation/x86/x86_64: (1/1) Documentation/scsi: (4/4) Documentation/filesystems: (2/9) Documentation/filesystems/nfs: (0/2) Documentation/cgroup-v1: (0/2) Documentation/kbuild: (0/4) Documentation/spi: (1/0) Documentation/virtual/kvm: (1/0) Documentation/scheduler: (0/2) Documentation/fb: (0/1) Documentation/block: (0/1) Documentation/networking: (6/37) Documentation/vm: (1/3) Then there are 364 subdirectories in Documentation/ with several files that are missing 00-INDEX alltogether (and another 120 with a single file and no 00-INDEX). I don't really have an opinion to whether or not we /should/ have 00-INDEX, but the above 00-INDEX should either be removed or be kept up to date. If we should keep the files, I can try to keep them updated, but I rather not if we just want to delete them anyway. As a starting point, remove all index-files and references to 00-INDEX and see where the discussion is going. Signed-off-by: Henrik Austad <henrik@austad.us> Acked-by: "Paul E.

2017-02-14cdrom: Make device operations read-onlyKees Cook
Since function tables are a common target for attackers, it's best to keep them in read-only memory. As such, this makes the CDROM device ops tables const. This drops additionally n_minors, since it isn't used meaningfully, and sets the only user of cdrom_dummy_generic_packet explicitly so the variables can all be const.

Now there are also some addresses pointing to .spec files some are located, but some(after searching on the companies site)where still no where to be found.

2009-12-13ide: doc: remove compilation options section from ide-cd documentationThadeu Lima de Souza Cascardo
This section pointed out to compilation options which no longer exist. VERBOSE_IDE_CD_ERRORS has been replace by config option CONFIG_BLK_DEV_IDECD_VERBOSE_ERRORS. STANDARD_ATAPI is no longer needed, since the non-standard drivers, which required bcd2bin are now detected, and there's a flag for them. NO_DOOR_LOCKING is now a sysctl parameter for cdrom drivers. CDROM_NBLOCKS_BUFFER is not used anymore. The READAUDIO is now in cdrom.c and it allocates as much as user space has requested to read, backing off if it fails. TEST is not there anymore or in cdrom either. ide allows to send ATA commands through ioctl, although it may be helpful to send MMC packets through the cdrom layer directly.

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!
