2007-07-30[SPARC]: Mark SBUS framebuffer ioctls as IGNORE in compat_ioctl.cDavid S. Miller
They are handled in a ->compat_ioctl() handler, so it's just noise when compat_ioctl.c warns which occurs when they are used on non-SBUS framebuffer devices. Signed-off-by: David S. Miller <davem@davemloft.net>

2007-05-25fix compat console unimap regressionHugh Dickins
Why is it that since the 2f1a2ccb9c0de632ab07193becf5f7121794f6ae console UTF-8 fixes went into 2.6.22-rc1, the PowerMac G5 shows only inverse video question marks for the text on tty2-6? whereas tty1 is fine, and so is x86. No fault of that patch: by removing the old fallback behaviour, it reveals that 32-bit setfont running on 64-bit kernels has only really worked on the current console, the rest getting faked by that inadequate fallback. Bring the compat do_unimap_ioctl into line with the main one: PIO_UNIMAP and GIO_UNIMAP apply to the specified tty, not redirected to fg_console. Use the same checks, and most particularly, remember to check access_ok: con_set_unimap and con_get_unimap are using __get_user and __put_user. And the compat vt_check should ask for the same capability as the main one, CAP_SYS_TTY_CONFIG rather than CAP_SYS_ADMIN. Added in vt_ioctl's vc_cons_allocated check for safety, though failure may well be impossible.

2007-05-10Allow compat_ioctl.c to compile without CONFIG_NETSimon Horman
A small regression appears to have been introduced in the recent patch "cleanup compat ioctl handling", which was included in Linus' tree after 2.6.20. siocdevprivate_ioctl() is no longer defined if CONFIG_NET is undefined, whereas previously it was a dummy function in this case. This causes compilation with CONFIG_COMPAT but without CONFIG_NET to fail. fs/compat_ioctl.c: In function `compat_sys_ioctl': fs/compat_ioctl.c:3571: warning: implicit declaration of function `siocdevprivate_ioctl' Cc: Christoph Hellwig <hch@lst.de> Acked-by: Arnd Bergmann <arnd@arndb.de> Cc: Andi Kleen <ak@suse.de> Signed-off-by: Andrew Morton <akpm@linux-foundation.org> Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>

Define a new IGNORE_IOCTL() to let a compat ioctl not be warned about even when it is not implemented. This is the same as COMPATIBLE_IOCTL internally, but better self documentng. Valid reasons to use this: - It is implemented with ->compat_ioctl on some device, but programs call it on others too. - The ioctl is not implemented in the native kernel, but programs call it commonly anyways. Most other reasons are not valid. Signed-off-by: Andi Kleen <ak@suse.de>

2006-09-30[PATCH] BLOCK: Make it possible to disable the block layer [try #6]David Howells
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.

2006-01-10[PATCH] sanitize building of fs/compat_ioctl.cChristoph Hellwig
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.

2006-01-09V4L (926_2): Moves compat32 functions from fs to v4l subsystemArnd Bergmann
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.

2005-11-20[COMPAT] net: SIOCGIFCONF data corruptionAlexandra Kossovsky
From: Alexandra Kossovsky <Alexandra.Kossovsky@oktetlabs.ru> From http://bugzilla.kernel.org/show_bug.cgi?id=4746 There is user data corruption when using ioctl(SIOCGIFCONF) in 32-bit application running amd64 kernel. I do not think that this problem is exploitable, but any data corruption may lead to security problems. Following code demonstrates the problem #include <stdint.h> #include <stdio.h> #include <sys/time.h> #include <sys/socket.h> #include <net/if.h> #include <sys/ioctl.h> char buf[256]; main() { int s = socket(AF_INET, SOCK_DGRAM, 0); struct ifconf req; int i; req.ifc_buf = buf; req.ifc_len = 41; printf("Result %d\n", ioctl(s, SIOCGIFCONF, &req)); printf("Len %d\n", req.ifc_len); for (i = 41; i < 256; i++) if (buf[i] != 0) printf("Byte %d is corrupted\n", i); } Steps to reproduce: Compile the code above into 32-bit elf and run it. You'll get Result 0 Len 32 Byte 48 is corrupted Byte 52 is corrupted Byte 53 is corrupted Byte 54 is corrupted Byte 55 is corrupted Signed-off-by: Andrew Morton <akpm@osdl.org> Signed-off-by: David S.

2005-11-09[PATCH] re-add TIOCSTART and TIOCSTOP compat_ioctl handlersChristoph Hellwig
We don't implement these ioctls, but some architectures define them in the headers. Bash picks them up and issues them frequently. Add compat_ioctl handlers to silence warnings about unhandled copat ioctls.

This is the fs/ part of the big kfree cleanup patch. Remove pointless checks for NULL prior to calling kfree() in fs/. Signed-off-by: Jesper Juhl <jesper.juhl@gmail.com> Signed-off-by: Andrew Morton <akpm@osdl.org> Signed-off-by: Linus Torvalds <torvalds@osdl.org>
2005-10-30[PATCH] TIOC* compat ioctl handlingChristoph Hellwig
TIOCSTART and TIOCSTOP are defined in asm/ioctls.h and asm/termios.h by various architectures but not actually implemented anywhere but in the IRIX compatibility layer, so remove their COMPATIBLE_IOCTL from parisc, ppc64 and sparc64. Move the TIOCSLTC COMPATIBLE_IOCTL to common code, guided by an ifdef to only show up on architectures that support it (same as the code handling it in tty_ioctl.c), aswell as it's brother TIOCGLTC that wasn't handled so far.
