fix compat console unimap regression

2007-05-26T00:37:46+00:00

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.

Allow compat_ioctl.c to compile without CONFIG_NET

2007-05-10T20:34:05+00:00

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.

cleanup compat ioctl handling

2007-05-08T18:15:09+00:00

Merge all compat ioctl handling into compat_ioctl.c instead of splitting it
over compat.c and compat_ioctl.c.  This also allows to get rid of ioctl32.h

merge compat_ioctl.h into compat_ioctl.c

2007-05-08T18:15:09+00:00

Now that there is no arch-specific compat ioctl handling left there is not
point in having a separate copat_ioctl.h, so merge it into compat_ioctl.c

Remove includes of  where it is not used/needed.

[PATCH] x86-64: Shut up warnings for vfat compat ioctls on other file systems

2007-05-02T17:27:21+00:00

vfat implements compat handlers for these ioctls, but when they
were executed on other file systems the kernel would still complain
about an unknown compat ioctl.  Just declare them as compatible
and let them be rejected when not needed by the normal path.

This makes wine runs a lot quieter

[PATCH] x86-64: Shut up 32bit emulation for SIOCGIFCOUNT

The kernel doesn't implement it, but some programs like java use it
anyways. Shut the code up.

[PATCH] x86-64: Define IGNORE_IOCTL() macro for compat_ioctls

2007-05-02T17:27:20+00:00

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.

[NET]: Introduce SIOCGSTAMPNS ioctl to get timestamps with nanosec resolution

2007-04-26T05:24:04+00:00

Now network timestamps use ktime_t infrastructure, we can add a new
ioctl() SIOCGSTAMPNS command to get timestamps in 'struct timespec'.
User programs can thus access to nanosecond resolution.
