* NFS: add "[no]resvport" mount optionChuck Lever2008-12-23
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The standard default security setting for NFS is AUTH_SYS. An NFS client connects to NFS servers via a privileged source port and a fixed standard destination port (2049). The client sends raw uid and gid numbers to identify users making NFS requests, and the server assumes an appropriate authority on the client has vetted these values because the source port is privileged. On Linux, by default in-kernel RPC services use a privileged port in the range between 650 and 1023 to avoid using source ports of well- known IP services. Using such a small range limits the number of NFS mount points and the number of unique NFS servers to which a client can connect concurrently. An NFS client can use unprivileged source ports to expand the range of source port numbers, allowing more concurrent server connections and more NFS mount points. Servers must explicitly allow NFS connections from unprivileged ports for this to work. In the past, bumping the value of the sunrpc.max_resvport sysctl on the client would permit the NFS client to use unprivileged ports. Bumping this setting also changes the maximum port number used by other in-kernel RPC services, some of which still required a port number less than 1023. This is exacerbated by the way source port numbers are chosen by the Linux RPC client, which starts at the top of the range and works downwards. It means that bumping the maximum means all RPC services requesting a source port will likely get an unprivileged port instead of a privileged one. Changing this setting effects all NFS mount points on a client. A sysadmin could not selectively choose which mount points would use non-privileged ports and which could not. Lastly, this mechanism of expanding the limit on the number of NFS mount points was entirely undocumented. To address the need for the NFS client to use a large range of source ports without interfering with the activity of other in-kernel RPC services, we introduce a new NFS mount option. This option explicitly tells only the NFS client to use a non-privileged source port when communicating with the NFS server for one specific mount point. This new mount option is called "resvport," like the similar NFS mount option on FreeBSD and Mac OS X. A sister patch for nfs-utils will be submitted that documents this new option in nfs(5). The default setting for this new mount option requires the NFS client to use a privileged port, as before. Explicitly specifying the "noresvport" mount option allows the NFS client to use an unprivileged source port for this mount point when connecting to the NFS server port. This mount option is supported only for text-based NFS mounts. [ Sidebar: it is widely known that security mechanisms based on the use of privileged source ports are ineffective. However, the NFS client can combine the use of unprivileged ports with the use of secure authentication mechanisms, such as Kerberos. This allows a large number of connections and mount points while ensuring a useful level of security. Eventually we may change the default setting for this option depending on the security flavor used for the mount. For example, if the mount is using only AUTH_SYS, then the default setting will be "resvport;" if the mount is using a strong security flavor such as krb5, the default setting will be "noresvport." ] Signed-off-by: Chuck Lever <chuck.lever@oracle.com> [Trond.Myklebust@netapp.com: Fixed a bug whereby nfs4_init_client() was being called with incorrect arguments.] Signed-off-by: Trond Myklebust <Trond.Myklebust@netapp.com>
* NFS: move nfs_server flag initializationChuck Lever2008-12-23
| | | | | | | | | | | | | Make it possible for the NFSv4 mount set up logic to pass mount option flags down the stack to nfs_create_rpc_client(). This is immediately useful if we want NFS mount options to modulate settings of the underlying RPC transport, but it may be useful at some later point if other parts of the NFSv4 mount initialization logic want to know what the mount options are.

* NFS: expand flags passed to nfs_create_rpc_client()Chuck Lever2008-12-23
| | | | | | | | | | | | | The nfs_create_rpc_client() function sets up an RPC client for an NFS mount point. Add an option that allows it to set up an RPC transport from an unprivileged port. Instead of having nfs_create_rpc_client()'s callers retain local knowledge about how to set up an RPC client, create a couple of flag arguments to control the use of RPC_CLNT_CREATE flags.

* lockd: convert reclaimer thread to kthread interfaceJeff Layton2008-12-23
| | | | | | | | | | | | | | | | | | | | | | | | | | My understanding is that there is a push to turn the kernel_thread interface into a non-exported symbol and move all kernel threads to use the kthread API. This patch changes lockd to use kthread_run to spawn the reclaimer thread. I've made the assumption here that the extra module references taken when we spawn this thread are unnecessary and removed them. I've also added a KERN_ERR printk that pops if the thread can't be spawned to warn the admin that the locks won't be reclaimed. In the future, it would be nice to be able to notify userspace that locks have been lost (probably by implementing SIGLOST), and adding some good policies about how long we should reattempt to reclaim the locks. Finally, I removed a comment about memory leaks that I believe is obsolete and added a new one to clarify the result of sending a SIGKILL to the reclaimer thread. As best I can tell, doing so doesn't actually cause a memory leak. I consider this patch 2.6.29 material.

* SUNRPC: Remove the last remnant of the BKL...Trond Myklebust2008-12-23
| | | | | | | | | | | | | | | | Somehow, this escaped the previous purge. There should be no need to keep any extra locks in the XDR callbacks. The NFS client XDR code only writes into private objects, whereas all reads of shared objects are confined to fields that do not change, such as filehandles... Ditto for lockd, the NFSv2/v3 client mount code, and rpcbind. The nfsd XDR code may require the BKL, but since it does a synchronous RPC call from a thread that already holds the lock, that issue is moot.

* nfs: remove redundant tests on reading new pagesWu Fengguang2008-12-23
| | | | | | | | | | | | | | | | | | | | | aops->readpages() and its NFS helper readpage_async_filler() will only be called to do readahead I/O for newly allocated pages. So it's not necessary to test for the always 0 dirty/uptodate page flags. The removal of nfs_wb_page() call also fixes a readahead bug: the NFS readahead has been synchronous since 2.6.23, because that call will clear PG_readahead, which is the reminder for asynchronous readahead. More background: the PG_readahead page flag is shared with PG_reclaim, one for read path and the other for write path. clear_page_dirty_for_io() unconditionally clears PG_readahead to prevent possible readahead residuals, assuming itself to be always called in the write path. However, NFS is one and the only exception in that it _always_ calls clear_page_dirty_for_io() in the read path, i.e. for readpages()/readpage().

* Null pointer deref with hrtimer_try_to_cancel()Thomas Gleixner2008-12-20
| | | | | | | | | | | | | | | | | | | | | Impact: Prevent kernel crash with posix timer clockid CLOCK_MONOTONIC_RAW commit 2d42244ae71d6c7b0884b5664cf2eda30fb2ae68 (clocksource: introduce CLOCK_MONOTONIC_RAW) introduced a new clockid, which is only available to read out the raw not NTP adjusted system time. The above commit did not prevent that a posix timer can be created with that clockid. The timer_create() syscall succeeds and initializes the timer to a non existing hrtimer base. When the timer is deleted either by timer_delete() or by the exit() cleanup the kernel crashes. Prevent the creation of timers for CLOCK_MONOTONIC_RAW by setting the posix clock function to no_timer_create which returns an error code.

(1) possible deadlock in microcode_resume_cpu() if either 'if' section is taken; (2) now, I don't see it in spec. and can't experimentally verify it (newer ucodes don't seem to be available for my Core2duo)... but logically-wise, I'd think that when read upon resuming, the 'microcode revision' (MSR 0x8B) should be back to its original one (we need to reload ucode anyway so it doesn't seem logical if a cpu doesn't drop the version)... if so, the comparison with memcmp() for the full 'struct cpu_signature' is wrong... and that's how one of the aforementioned 'if' sections might have been triggered - leading to a deadlock. Obviously, in my tests I simulated loading/resuming with the ucode of the same version (just to see that the file is loaded/re-loaded upon resuming) so this issue has never popped up. I'd appreciate if someone with an appropriate system might give a try to the 2nd patch (titled "fix a comparison && deadlock..."). In any case, the deadlock situation is a must-have fix.

Basically, drivers are supposed to terminate commands once error handling begins on them. The fusion apparently wasn't doing this. Under the old timeout regime, completions on terminated commands would by and large get ignored because of the way command timeouts used to work. The new block timers are very intolerant to this, though, becuase the request gets cleaned and freed.

Setting the extra hp_nid results in a non-working "Headpohne" mixer control. Thus hp_nid should be 0 for these dell models. Also, the automatic addition of hp_nid should check whether it's a dual-HP model or not. For dual-HPs, the pins are already checked by the early workaround.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Added the model without the jack-detection for some desktops that have really no jack-detection. The recent driver caused regressions regarding the sound output on such machines. Signed-off-by: Takashi Iwai <tiwai@suse.de>
