| * NLM: Support IPv6 scope IDs in nlm_display_address()Chuck Lever2009-01-061-6/+15
| | | | | | | | | | | | | | | | | | | | | | | | | | Scope ID support is needed since the kernel's NSM implementation is about to use these displayed addresses as a mon_name in some cases. When nsm_use_hostnames is zero, without scope ID support NSM will fail to handle peers that contact us via a link-local address. Link-local addresses do not work without an interface ID, which is stored in the sockaddr's sin6_scope_id field. Signed-off-by: Chuck Lever <chuck.lever@oracle.com> Signed-off-by: J.

| * NLM: Remove AF_UNSPEC arm in nlm_display_address()Chuck Lever2009-01-061-3/+0
| | | | | | | | | | | | | | | | | | AF_UNSPEC support is no longer needed in nlm_display_address() now that a presentation address is no longer generated for the h_srcaddr field. Signed-off-by: Chuck Lever <chuck.lever@oracle.com> Signed-off-by: J. Bruce Fields <bfields@citi.umich.edu>
| * NLM: Remove address eye-catcher buffers from nlm_hostChuck Lever2009-01-061-7/+3
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The h_name field in struct nlm_host is a just copy of h_nsmhandle->sm_name. Likewise, the contents of the h_addrbuf field should be identical to the sm_addrbuf field. The h_srcaddrbuf field is used only in one place for debugging. We can live without this until we get %pI formatting for printk(). Currently these buffers are 48 bytes, but we need to support scope IDs in IPv6 presentation addresses, which means making the buffers even larger. Instead, let's find ways to eliminate them to save space. Signed-off-by: Chuck Lever <chuck.lever@oracle.com> Signed-off-by: J. Bruce Fields <bfields@citi.umich.edu>
| * lockd: set svc_serv->sv_maxconn to a more reasonable value (try #3)Jeff Layton2009-01-061-0/+8
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The default method for calculating the number of connections allowed per RPC service arbitrarily limits single-threaded services to 80 connections. This is too low for services like lockd and artificially limits the number of TCP clients that it can support. Have lockd set a default sv_maxconn value to 1024 (which is the typical default value for RLIMIT_NOFILE. Also add a module parameter to allow an admin to set this to an arbitrary value.

| * | debugfs: add helpers for exporting a size_t simple valueInaky Perez-Gonzalez2009-01-071-0/+32
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | In the same spirit as debugfs_create_*(), introduce helpers for exporting size_t values over debugfs. The only trick done is that the format verifier is kept at %llu instead of %zu; otherwise type warnings would pop up: format ‘%zu’ expects type ‘size_t’, but argument 2 has type ‘long long unsigned int’ There is no real way to fix this one--however, we can consider %llu and %zu to be compatible if we consider that we are using the same for validating in debugfs_create_{x,u}{8,16,32}().

BKL doesn't matter to possible refcount leak as well. 2) proc_lookup_de() ------------------- Walking PDE list is protected by proc_subdir_lock(), proc_get_inode() is potentially blocking, all callers of proc_lookup_de() eventually end up from ->lookup hooks which is protected by directory's ->i_mutex -- BKL doesn't protect anything. 3) proc_readdir_de() -------------------- "." and ".." part doesn't need BKL, walking PDE list is under proc_subdir_lock, calling filldir callback is potentially blocking because it writes to luserspace. All proc_readdir_de() callers eventually come from ->readdir hook which is under directory's ->i_mutex -- BKL doesn't protect anything. 4) proc_root_readdir_de() ------------------------- proc_root_readdir_de is ->readdir hook, see (3). Since readdir hooks doesn't use BKL anymore, switch to generic_file_llseek, since it also takes directory's i_mutex. Signed-off-by: Alexey Dobriyan <adobriyan@gmail.com>

To support this, fuse client can request retry of ioctl specifying memory regions to read and write. Deep copying (nested pointers) can be implemented by retrying multiple times resolving one depth of dereference at a time. For security and cleanliness considerations, ioctl implementation has restricted mode where the kernel determines data transfer directions and sizes using the _IOC_*() macros on the ioctl command. In this mode, retry is not allowed. For all FUSE servers, restricted mode is enforced. Unrestricted ioctl will be used by CUSE.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Since all sanity checks rely on the validity of s_start which gets only checked to be smaller than s_end, we should also check if s_end is sane. Now we also try to retrieve the last block of the filesystem, which is computed by s_end. If this fails, something is bogus.

* | | | bfs: add some basic sanity checksEric Sesterhenn2009-01-061-0/+33
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | bfs_fill_super() already touches all inodes, so we can easily add some cheap sanity checks and check if the inode start and end blocks are smaller than the maximum number of blocks, the inode start block lies behind the end block or the file end offset is behind the end of the filesystem. Also check if the start of data offset in the super block fits the filesystem. The added sanity checks catch softlockup issues early when we try to sb_bread() lots of blocks in a loop in bfs_readdir() and bfs_find_entry(). In addition an oom issue in bfs_fill_super() is prevented by this when s_start is corrupted, which influences imap_len and we try to allocate a huge info->si_imap.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | In function validate_dev_ioctl() we check that the string we've been sent is a valid path. The function that does this check assumes the string is NULL terminated but our NULL termination check isn't done until after this call. This patch changes the order of the check.

This was done because 0 and AUTOFS_TYPE_INDIRECT were being treated implicitly as the same type. - previously, an offset mount had it's type set to AUTOFS_TYPE_DIRECT|AUTOFS_TYPE_OFFSET but the mount control re-implementation needs to be able distinguish all three types. So this was changed to make the type setting explicit. - a type AUTOFS_TYPE_ANY was added for use by the re-implementation when checking if a given path is a mountpoint. It's not really a type as we use this to ask if a given path is a mountpoint in the autofs_dev_ioctl_ismountpoint() function. - functions to set and test the autofs mount types have been added to improve readability and make the type usage explicit. - the mount type is used from user space for the mount control re-implementtion so, for consistency, all the definitions have been moved to the user space include file include/linux/auto_fs4.h.
