| * fs: do not assign default i_ino in new_inodeChristoph Hellwig2010-10-251-0/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Instead of always assigning an increasing inode number in new_inode move the call to assign it into those callers that actually need it. For now callers that need it is estimated conservatively, that is the call is added to all filesystems that do not assign an i_ino by themselves. For a few more filesystems we can avoid assigning any inode number given that they aren't user visible, and for others it could be done lazily when an inode number is actually needed, but that's left for later patches.

| * | SUNRPC: Properly initialize sock_xprt.srcaddr in all casesChuck Lever2010-10-211-1/+32
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The source address field in the transport's sock_xprt is initialized ONLY IF the RPC application passed a pointer to a source address during the call to rpc_create(). However, xs_bind() subsequently uses the value of this field without regard to whether the source address was initialized during transport creation or not. So far we've been lucky: the uninitialized value of this field is zeroes. xs_bind(), until recently, used only the sin[6]_addr field in this sockaddr, and all zeroes is a valid value for this: it means ANYADDR. This is a happy coincidence. However, xs_bind() now wants to use the sa_family field as well, and expects it to be initialized to something other than zero. Therefore, the source address sockaddr field should be fully initialized at transport create time in _every_ case, not just when the RPC application wants to use a specific bind address. Bruce added a workaround for this missing initialization by adjusting commit 6bc9638a, but the "right" way to do this is to ensure that the source address sockaddr is always correctly initialized from the get-go. This patch doesn't introduce a behavior change. It's simply a clean-up of Bruce's fix, to prevent future problems of this kind. It may look like overkill, but a) it clearly documents the default initial value of this field, b) it doesn't assume that the sockaddr_storage memory is first initialized to any particular value, and c) it will fail verbosely if some unknown address family is passed in Originally introduced by commit d3bc9a1d.

The imposition of this limit is spread about a bit - sometime we don't add new things to the list, sometimes we remove old things. Also it is currently applied to requests which we are 'waiting' for rather than 'deferring'. This doesn't seem ideal as 'waiting' requests are naturally limited by the number of threads. So gather the DFR_MAX handling code to one place and only apply it to requests that are actually being deferred. This means that not all 'cache_deferred_req' structures go on the 'cache_defer_list, so we need to be careful when adding and removing things.

Various different error codes are returned, but the single caller is only interested in success or failure. In fact it can measure this success or failure itself by checking CACHE_PENDING, which makes the point of the code more explicit. So change cache_defer_req to return 'void' and test CACHE_PENDING after it completes, to see if the request was actually deferred or not. Similarly setup_deferral and cache_wait_req don't need a return value, so make them void and remove some code. The call to cache_revisit_request (to guard against a race) is only needed for the second call to setup_deferral, so move it out of setup_deferral to after that second call. With the first call the race is handled differently (by explicitly calling 'wait_for_completion'). Signed-off-by: NeilBrown <neilb@suse.de> Signed-off-by: J. Bruce Fields <bfields@redhat.com>

So when our setup_deferral calls cache_revisit_request it will find nothing to put on the pending list, and do nothing. We then return from cache_wait_req, thus leaving the 'sleeper' on-stack structure open to being corrupted by subsequent stack usage. However that 'sleeper' could still be on the 'pending' list that the other thread is looking at and so any corruption could cause it to behave badly. To avoid this race we simply take the same path as if the 'wait_for_completion_interruptible_timeout' was interrupted and if the sleeper is no longer on the list (which it won't be) we wait on the completion - which will ensure that any other cache_revisit_request will have let go of the sleeper.

This actually causes a build failure on a sparc32 defconfig build: `rpcauth_remove_module' referenced in section `.init.text' of net/built-in.o: defined in discarded section `.exit.text' of net/built-in.o I applied the following patch for today: Fixes: `rpcauth_remove_module' referenced in section `.init.text' of net/built-in.o: defined in discarded section `.exit.text' of net/built-in.o Signed-off-by: Stephen Rothwell <sfr@canb.auug.org.au> Acked-by: Pavel Emelyanov <xemul@openvz.org> Signed-off-by: J.

| | | | | | | | | | | | | | | | | | | | | | | | | | | There are two calls that operate on ip_map_cache and are directly called from the nfsd code. Other places will be handled in a different way. Signed-off-by: Pavel Emelyanov <xemul@openvz.org> Signed-off-by: J. Bruce Fields <bfields@redhat.com>
