* [PATCH] sanitize lookup_hash prototypeChristoph Hellwig2005-11-09
| | | | | | | | | | | | | | | | | | | | | | | ->permission and ->lookup have a struct nameidata * argument these days to pass down lookup intents. Unfortunately some callers of lookup_hash don't actually pass this one down. For lookup_one_len() we don't have a struct nameidata to pass down, but as this function is a library function only used by filesystem code this is an acceptable limitation. All other callers should pass down the nameidata, so this patch changes the lookup_hash interface to only take a struct nameidata argument and derives the other two arguments to __lookup_hash from it. All callers already have the nameidata argument available so this is not a problem. At the same time I'd like to deprecate the lookup_hash interface as there are better exported interfaces for filesystem usage. Before it can actually be removed I need to fix up rpc_pipefs.

* [PATCH] add a file_permission helperChristoph Hellwig2005-11-09
| | | | | | | | | | | | A few more callers of permission() just want to check for a different access pattern on an already open file. This patch adds a wrapper for permission() that takes a file in preparation of per-mount read-only support and to clean up the callers a little. The helper is not intended for new code, everything without the interface set in stone should use vfs_permission() Signed-off-by: Christoph Hellwig <hch@lst.de> Signed-off-by: Andrew Morton <akpm@osdl.org> Signed-off-by: Linus Torvalds <torvalds@osdl.org>
* [PATCH] add a vfs_permission helperChristoph Hellwig2005-11-09
| | | | | | | | | | | Most permission() calls have a struct nameidata * available. This helper takes that as an argument and thus makes sure we pass it down for lookup intents and prepares for per-mount read-only support where we need a struct vfsmount for checking whether a file is writeable.

| | | | | | | | | | | | | | | | | | | | | This patch removes almost all inclusions of linux/version.h. The 3 #defines are unused in most of the touched files. A few drivers use the simple KERNEL_VERSION(a,b,c) macro, which is unfortunatly in linux/version.h. There are also lots of #ifdef for long obsolete kernels, this was not touched.

* [PATCH] cpu hotplug: fix locking in cpufreq driversAshok Raj2005-11-09
| | | | | | | | | | | | | | | | | | | | | | | | | When calling target drivers to set frequency, we take cpucontrol lock. When we modified the code to accomodate CPU hotplug, there was an attempt to take a double lock of cpucontrol leading to a deadlock. Since the current thread context is already holding the cpucontrol lock, we dont need to make another attempt to acquire it. Now we leave a trace in current->flags indicating current thread already is under cpucontrol lock held, so we dont attempt to do this another time.

* [PATCH] Fix sysctl unregistration oops (CVE-2005-2709)Al Viro2005-11-08
| | | | | | | | | | | | | | | You could open the /proc/sys/net/ipv4/conf/<if>/<whatever> file, then wait for interface to go away, try to grab as much memory as possible in hope to hit the (kfreed) ctl_table. Then fill it with pointers to your function. Then do read from file you've opened and if you are lucky, you'll get it called as ->proc_handler() in kernel mode. So this is at least an Oops and possibly more. It does depend on an interface going away though, so less of a security risk than it would otherwise be.

* [PPP]: add PPP MPPE encryption moduleMatt Domsch2005-11-08
| | | | | | | | | | | | | | | | | | | | | | | | | | | | From: Matt Domsch <Matt_Domsch@dell.com> The patch below implements the Microsoft Point-to-Point Encryption method as a PPP compressor/decompressor. This is necessary for Linux clients and servers to interoperate with Microsoft Point-to-Point Tunneling Protocol (PPTP) servers (either Microsoft PPTP servers or the poptop project) which use MPPE to encrypt data when creating a VPN. This patch differs from the kernel_ppp_mppe DKMS pacakge at pptpclient.sourceforge.net by utilizing the kernel crypto routines rather than providing its own SHA1 and arcfour implementations. Minor changes to ppp_generic.c try to prevent a link from disabling compression (in our case, the encryption) after it has started using compression (encryption).

* | [PATCH] unbindable mountsRam Pai2005-11-07
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | An unbindable mount does not forward or receive propagation. Also unbindable mount disallows bind mounts. The semantics is as follows. Bind semantics: It is invalid to bind mount an unbindable mount. Move semantics: It is invalid to move an unbindable mount under shared mount. Clone-namespace semantics: If a mount is unbindable in the parent namespace, the corresponding cloned mount in the child namespace becomes unbindable too. Note: there is subtle difference, unbindable mounts cannot be bind mounted but can be cloned during clone-namespace.

* | [PATCH] saner handling of auto_acct_off() and DQUOT_OFF() in umountAl Viro2005-11-07
|/ | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The way we currently deal with quota and process accounting that might keep vfsmount busy at umount time is inherently broken; we try to turn them off just in case (not quite correctly, at that) and a) pray umount doesn't fail (otherwise they'll stay turned off) b) pray nobody doesn anything funny just as we turn quota off Moreover, LSM provides hooks for doing the same sort of broken logics. The proper way to deal with that is to introduce the second kind of reference to vfsmount. Semantics: - when the last normal reference is dropped, all special ones are converted to normal ones and if there had been any, cleanup is done. - normal reference can be cloned into a special one - special reference can be converted to normal one; that's a no-op if we'd already passed the point of no return (i.e. mntput() had converted special references to normal and started cleanup). The way it works: e.g. starting process accounting converts the vfsmount reference pinned by the opened file into special one and turns it back to normal when it gets shut down; acct_auto_close() is done when no normal references are left. That way it does *not* obstruct umount(2) and it silently gets turned off when the last normal reference to vfsmount is gone. Which is exactly what we want... The same should be done by LSM module that holds some internal references to vfsmount and wants to shut them down on umount - it should make them special and security_sb_umount_close() will be called exactly when the last normal reference to vfsmount is gone. quota handling is even simpler - we don't use normal file IO anymore, so there's no need to hold vfsmounts at all. DQUOT_OFF() is done from deactivate_super(), where it really belongs. Signed-off-by: Al Viro <viro@zeniv.linux.org.uk> Signed-off-by: Linus Torvalds <torvalds@osdl.org>

This summary information is stored in a JFFS2_FEATURE_RWCOMPAT_DELETE. During the mount process if there is no summary info the orignal scan process will be executed. EBS works with NAND and NOR flashes, too. There is a user space tool called sumtool to generate this summary information for a JFFS2 image.

This _may_ help to avoid global synchronisation during small bursts of peers advertising but not caring about ECN. Use this option very carefully, it does more harm than good if (qth_max - qth_min) does not cover at least two average burst cycles. The difference to the current behaviour, in which we'd run into the hard queue limit, is that due to the low pass filter of RED short bursts are less likely to cause a global synchronisation.
