| | | | | | | | | | | | | | | | | | | | | | | | | | As reported by Sam Ravnborg, Gcc-3.4.5 does not handle: if (get_user() || get_user()) with the new branch tracer enabled.

| | | | | | | | | | | | | | | | | | | | | | | | Fix warnings caused by the unsigned long long usage in sparc specific drivers. The drivers were considered sparc specific more or less from the filename alone.

| * sparc64: Use unsigned long long for u64.Sam Ravnborg2009-01-0619-71/+71
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Andrew Morton wrote: People keep on doing printk("%llu", some_u64); testing it only on x86_64 and this generates a warning storm on powerpc, sparc64, etc. Because they use `long', not `long long'. Quite a few 64-bit architectures are using `long' for their s64/u64 types. We should convert them all to `long long'. Update types.h so we use unsigned long long for u64 and fix all warnings in sparc64 code. Tested with an allnoconfig, defconfig and allmodconfig builds. This patch introduces additional warnings in several drivers. These will be dealt with in separate patches.

| * sparc: refactor code in fault_32.cSam Ravnborg2009-01-061-1/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The sparc allmodconfig build broke due to enabling of the branch_tracer that does some very clever things with all if conditions. This caused my gcc 3.4.5 to be so confused that it emitted a warning: arch/sparc/mm/fault_32.c: In function `do_sparc_fault': arch/sparc/mm/fault_32.c:176: warning: 'fixup' might be used uninitialized in this function And with -Werror this broke the build.

| * | V4L/DVB (10191a): Update MAINTAINERS entries on media driversMauro Carvalho Chehab2009-01-071-23/+42
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch updates the MAINTAINERS entries for the media drivers. We are doing a few changes during 2009 to improve patch handling for drivers/media stuff. Currently, v4l-dvb-maintainer list at linuxtv.org were used to to be v4l/dvb driver maintainers ML, in order to keep track of patch merge requests and to receive bug fixes. This list allows posting for everybody, but, in order to avoid spam, the user subscribe/unsubscribe at the ML is moderated. Other development discussions and end-user forums happened on two separated ML (one for V4L and another for DVB). At the beginning of 2009, we've created linux-media@vger.kernel.org, meaning to be the main upstream development mailing list for drivers/media, including V4L and DVB core and drivers. The choice for vger.kernel.org were due to the fact that most of upstream lists are there. Also, its anti-spam filtering rules are better than what we currently have at linuxtv.org. For now, both video4linux-list and linux-dvb ML will remain active, but more focused on end users. It is expected that those lists will gradually be replaced also by linux-media@vger.kernel.org. This patch reflect those changes at linux MAINTAINERS file. Since the development and bug fix discussions will now happen at linux-media@vger.kernel.org, this patch does the following changes - replaces v4l-dvb-maintainer ML for the new linux-media@vger.kernel.org; - replaces video4linux ML for the new linux-media@vger.kernel.org; While here, it also: - Fixes the existing -git tree entries for drivers/media (since the repository name changed); - Adds the missing drivers/media -git tree entry on a few maintainers entries that don't point to a tree.

| * | V4L/DVB (10190): cx88: Fix some Kbuild troublesMauro Carvalho Chehab2009-01-076-47/+65
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | As Randy Dunlap <randy.dunlap@oracle.com> reported, cx88 has some compilation issues: drivers/built-in.o: In function `cx88_call_i2c_clients': (.text+0x20af17): undefined reference to `videobuf_dvb_get_frontend' drivers/built-in.o: In function `cx8802_probe': cx88-mpeg.c:(.devinit.text+0x268c4): undefined reference to `videobuf_dvb_alloc_frontend' cx88-mpeg.c:(.devinit.text+0x268ea): undefined reference to `videobuf_dvb_dealloc_frontends' With those configs: CONFIG_VIDEO_CX88=y CONFIG_VIDEO_CX88_BLACKBIRD=y CONFIG_VIDEO_CX88_DVB=m CONFIG_DVB_CORE=m After carefully examining the code, with the current code, several cx88 drivers (cx8800, cx8802, cx88_dvb and cx88_blackbird) should be compiled as a module, if one of them is marked as such. Just fixing Kconfig could create a very complex set of rules. Also, this hides a problem with the current approach where the dvb functionality weren't confined inside dvb module. What happens is that: - cx88-i2c (part of cx8800) has some special rules if DVB; - cx88-mpeg (cx8802 module) has also part of DVB init code; - cx88-dvb has the rest of the dvb code; - cx88-blackbird can be used with cx88-mpeg, having cx88-dvb or not. So, instead of doing some tricks at Kconfig and wait for a next breakage, this patch moves the dvb code inside cx88-i2c and cx88-mpeg into cx88-dvb. Another problem is that cx8802 were being compiled, even without cx88-dvb and cx88-blackbird modules. While on this code, let's fix also a reported problem: http://www.linuxtv.org/pipermail/linux-dvb/2009-January/031225.html A solution for the issue were proposed here: http://www.mail-archive.com/linux-media@vger.kernel.org/msg00021.html Thanks to Randy, Andy, Gregoire and Thomas for helping us to detect and solve the issues.

Revert the parts of those patches that touch nfsd. Note: we can't, however, remove the logic from vfs_fsync that was needed only for the special case of nfsd, because a vfs_fsync(NULL,...) call can still result indirectly from a stackable filesystem that was called by nfsd.

(2) The UID to use for fs accesses is in new->fsuid, not new->uid (which is 0).

But we forgot to initialize the file operations, with the result that LOCKT never results in a call to the filesystem's ->lock() method (if it exists). We could just add that one more initialization. But this hack of faking up a struct file with only some fields initialized seems the kind of thing that might cause more problems in the future. We should either do an open and get a real struct file, or make lock-testing an inode (not a file) method. This patch does the former.

It recognizes IPv4 privileged callers (from "127.0.0.1"), and IPv6 privileged callers (from "::1"). However, IPV6_ADDR_LOOPBACK is not set for the mapped IPv4 loopback address (::ffff:7f00:0001), so the test breaks when the kernel's RPC service is IPv6-enabled but user space is calling via the IPv4 loopback address. This is actually the most common case for IPv6- enabled RPC services on Linux. Rewrite the IPv6 check to handle the mapped IPv4 loopback address as well as a normal IPv6 loopback address.

Part of this service includes a second protocol, known as NSM, which is a reboot notification service. NLM uses this service to determine when to reclaim locks or enter a grace period after a client or server reboots. The NLM service (implemented by lockd in the Linux kernel) contacts the local NSM service (implemented by rpc.statd in Linux user space) via NSM protocol upcalls to register a callback when a particular remote peer reboots. To match the callback to the correct remote peer, the NLM service constructs a cookie that it passes in the request. The NSM service passes that cookie back to the NLM service when it is notified that the given remote peer has indeed rebooted. Currently on Linux, the cookie is the raw 32-bit IPv4 address of the remote peer. To support IPv6 addresses, which are larger, we could use all 16 bytes of the cookie to represent a full IPv6 address, although we still can't represent an IPv6 address with a scope ID in just 16 bytes. Instead, to avoid the need for future changes to support additional address types, we'll use a manufactured value for the cookie, and use that to find the corresponding nsm_handle struct in the kernel during the NLMPROC_SM_NOTIFY callback. This should provide complete support in the kernel's NSM implementation for IPv6 hosts, while remaining backwards compatible with older rpc.statd implementations. Note we also deal with another case where nsm_use_hostnames can change while there are outstanding notifications, possibly resulting in the loss of reboot notifications. After this patch, the priv cookie is always used to lookup rebooted hosts in the kernel. Signed-off-by: Chuck Lever <chuck.lever@oracle.com> Signed-off-by: J. Bruce Fields <bfields@citi.umich.edu>
