* [PATCH] 32-bit compatibility HDIO IOCTLsMaciej W. Rozycki2006-10-11
| | | | | | | | | | | | | | | | | | | | | A couple of HDIO IOCTLs are not yet handled and a few others are marked as using a pointer rather than an unsigned long. The formers include: HDIO_GET_WCACHE, HDIO_GET_ACOUSTIC, HDIO_GET_ADDRESS and HDIO_GET_BUSSTATE. The latters are: HDIO_SET_MULTCOUNT, HDIO_SET_UNMASKINTR, HDIO_SET_KEEPSETTINGS, HDIO_SET_32BIT, HDIO_SET_NOWERR, HDIO_SET_DMA, HDIO_SET_PIO_MODE and HDIO_SET_NICE. Additionally 0x330 used to be HDIO_GETGEO_BIG and may be issued by 32-bit `hdparm' run on a 64-bit kernel making Linux complain loudly. This is a fix for these issues. Signed-off-by: Maciej W.

| | | | | | | | | | | | | The ncp specific compat ioctls are clearly local to one file system, so the code can better live there. This version of the patch moves everything into the generic ioctl handler and uses it for both 32 and 64 bit calls.

* [PATCH] BLOCK: Make it possible to disable the block layer [try #6]David Howells2006-09-30
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Make it possible to disable the block layer. Not all embedded devices require it, some can make do with just JFFS2, NFS, ramfs, etc - none of which require the block layer to be present. This patch does the following: (*) Introduces CONFIG_BLOCK to disable the block layer, buffering and blockdev support. (*) Adds dependencies on CONFIG_BLOCK to any configuration item that controls an item that uses the block layer. This includes: (*) Block I/O tracing. (*) Disk partition code. (*) All filesystems that are block based, eg: Ext3, ReiserFS, ISOFS. (*) The SCSI layer. As far as I can tell, even SCSI chardevs use the block layer to do scheduling. Some drivers that use SCSI facilities - such as USB storage - end up disabled indirectly from this. (*) Various block-based device drivers, such as IDE and the old CDROM drivers. (*) MTD blockdev handling and FTL. (*) JFFS - which uses set_bdev_super(), something it could avoid doing by taking a leaf out of JFFS2's book. (*) Makes most of the contents of linux/blkdev.h, linux/buffer_head.h and linux/elevator.h contingent on CONFIG_BLOCK being set. sector_div() is, however, still used in places, and so is still available. (*) Also made contingent are the contents of linux/mpage.h, linux/genhd.h and parts of linux/fs.h. (*) Makes a number of files in fs/ contingent on CONFIG_BLOCK. (*) Makes mm/bounce.c (bounce buffering) contingent on CONFIG_BLOCK. (*) set_page_dirty() doesn't call __set_page_dirty_buffers() if CONFIG_BLOCK is not enabled. (*) fs/no-block.c is created to hold out-of-line stubs and things that are required when CONFIG_BLOCK is not set: (*) Default blockdev file operations (to give error ENODEV on opening). (*) Makes some /proc changes: (*) /proc/devices does not list any blockdevs. (*) /proc/diskstats and /proc/partitions are contingent on CONFIG_BLOCK. (*) Makes some compat ioctl handling contingent on CONFIG_BLOCK. (*) If CONFIG_BLOCK is not defined, makes sys_quotactl() return -ENODEV if given command other than Q_SYNC or if a special device is specified. (*) In init/do_mounts.c, no reference is made to the blockdev routines if CONFIG_BLOCK is not defined. This does not prohibit NFS roots or JFFS2. (*) The bdflush, ioprio_set and ioprio_get syscalls can now be absent (return error ENOSYS by way of cond_syscall if so). (*) The seclvl_bd_claim() and seclvl_bd_release() security calls do nothing if CONFIG_BLOCK is not set, since they can't then happen.

* [PATCH] vcsa attribute bits -> ioctl(VT_GETHIFONTMASK)Samuel Thibault2006-08-27
| | | | | | | | | | | | | | | | When reading /dev/vcsa while a font with more than 256 characters is loaded, one of the attribute bits records the 9th bit of the character. But depending on the console driver (vgacon or fbcon for instance), that's bit 3 or bit 0. And there is no way for userland to know that, thus no way for userland to safely grab the screen content. So here is a (tested) patch: Add a VT_GETHIFONTMASK ioctl for knowing which bit is the 9th bit for VC text (vc_hi_font_mask field of the vc_data structure).

* [PATCH] sanitize building of fs/compat_ioctl.cChristoph Hellwig2006-01-10
| | | | | | | | | | | | | | | | | | | | | | | Now that all these entries in the arch ioctl32.c files are gone [1], we can build fs/compat_ioctl.c as a normal object and kill tons of cruft. We need a special do_ioctl32_pointer handler for s390 so the compat_ptr call is done. This is not needed but harmless on all other architectures. Also remove some superflous includes in fs/compat_ioctl.c Tested on ppc64. [1] parisc still had it's PPP handler left, which is not fully correct for ppp and besides that ppp uses the generic SIOCPRIV ioctl so it'd kick in for all netdevice users. We can introduce a proper handler in one of the next patch series by adding a compat_ioctl method to struct net_device but for now let's just kill it - parisc doesn't compile in mainline anyway and I don't want this to block this patchset.

* V4L (926_2): Moves compat32 functions from fs to v4l subsystemArnd Bergmann2006-01-09
| | | | | | | | | | | | | | | | | | | This moves the 32 bit ioctl compatibility handlers for Video4Linux into a new file and adds explicit calls to them to each v4l device driver. Unfortunately, there does not seem to be any code handling the v4l2 ioctls, so quite often the code goes through two separate conversions, first from 32 bit v4l to 64 bit v4l, and from there to 64 bit v4l2. My patch does not change that, so there is still much room for improvement. Also, some drivers have additional ioctl numbers, for which the conversion should be handled internally to that driver.

We had similar problems with other ioctls where userspace did things like that. What we did there was to put the compat handler to generic code. The patch below does that, adding a big comment about what's going on and removing the COMPAT_IOCTL entires for these on powerpc that not only weren't ever useful but are duplicated now aswell.

* [SPARC64/COMPAT]: Add some compat ioctl for ppdevRaphael Assenat2005-07-04
| | | | | | | | | | | | | | | | | | | | | | | | | | The following patch adds some ioctls to include/linux/compat_ioctl.h to allow using ppdev from the 32 bit user space on sparc64. This patch also adds the PPDEV option in the sparc64 menu, near Parallel printer support in the 'General machine setup' submenu. All those ioctls seem to be compatible, since (correct me if I'm wrong) they dont use the 'long' type. See include/linux/ppdev.h. The application I used to test the new ioctls only used the following: PPEXCL PPCLAIM PPNEGOT PPGETMODES PPRCONTROL PPWCONTROL PPDATADIR PPWDATA PPRDATA But I beleive that the other ioctls will work fine.

* Linux-2.6.12-rc2v2.6.12-rc2Linus Torvalds2005-04-16
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!
