2011-07-20make d_splice_alias(ERR_PTR(err), dentry) = ERR_PTR(err)Al Viro15-94/+39
... and simplify the living hell out of callers Signed-off-by: Al Viro <viro@zeniv.linux.org.uk>
2011-07-20deuglify squashfs_lookup()Al Viro1-4/+1
d_splice_alias(NULL, dentry) is equivalent to d_add(dentry, NULL), NULL so no need for that if (inode) ... in there (or ERR_PTR(0), for that matter) Signed-off-by: Al Viro <viro@zeniv.linux.org.uk>
2011-07-20nfsd4_list_rec_dir(): don't bother with reopening rec_fileAl Viro1-31/+21
just rewind it to the beginning before vfs_readdir() and be done with that... Signed-off-by: Al Viro <viro@zeniv.linux.org.uk>
2011-07-20kill useless checks for sb->s_op == NULLAl Viro3-3/+2

2011-07-20btrfs: kill magical embedded struct superblockAl Viro5-22/+31

2011-07-20get rid of pointless checks for dentry->sb == NULLAl Viro2-2/+1
it never is... Signed-off-by: Al Viro <viro@zeniv.linux.org.uk>
2011-07-20Make ->d_sb assign-once and always non-NULLAl Viro3-39/+47
New helper (non-exported, fs/internal.h-only): __d_alloc(sb, name). Allocates dentry, sets its ->d_sb to given superblock and sets ->d_op accordingly. Old d_alloc(NULL, name) callers are converted to that (all of them know what superblock they want). d_alloc() itself is left only for parent != NULl case; uses __d_alloc(), inserts result into the list of parent's children. Note that now ->d_sb is assign-once and never NULL *and* ->d_parent is never NULL either. Signed-off-by: Al Viro <viro@zeniv.linux.org.uk>
2011-07-20unexport kern_path_parent()Al Viro1-1/+0
Signed-off-by: Al Viro <viro@zeniv.linux.org.uk>
2011-07-20switch vfs_path_lookup() to struct pathAl Viro5-28/+26
Signed-off-by: Al Viro <viro@zeniv.linux.org.uk>
2011-07-20kill lookup_create()Al Viro2-37/+18
folded into the only caller (kern_path_create()) Signed-off-by: Al Viro <viro@zeniv.linux.org.uk>
2011-07-20devtmpfs: get rid of bogus mkdir in create_path()Al Viro1-24/+18
We do _NOT_ want to mkdir the path itself - we are preparing to mknod it, after all. Normally it'll fail with -ENOENT and just do nothing, but if somebody has created the parent in the meanwhile, we'll get buggered... Signed-off-by: Al Viro <viro@zeniv.linux.org.uk>
2011-07-20switch devtmpfs to kern_path_create()Al Viro1-47/+36
Signed-off-by: Al Viro <viro@zeniv.linux.org.uk>
2011-07-20switch devtmpfs object creation/removal to separate kernel threadAl Viro1-73/+149
... and give it a namespace where devtmpfs would be mounted on root, thus avoiding abuses of vfs_path_lookup() (it was never intended to be used with LOOKUP_PARENT). Games with credentials are also gone. Signed-off-by: Al Viro <viro@zeniv.linux.org.uk>
2011-07-20make sure that nsproxy_cache is initialized early enoughAl Viro3-3/+3
Signed-off-by: Al Viro <viro@zeniv.linux.org.uk>
2011-07-20switch do_spufs_create() to user_path_create(), fix double-unlockAl Viro3-32/+21
Signed-off-by: Al Viro <viro@zeniv.linux.org.uk>
2011-07-20new helpers: kern_path_create/user_path_createAl Viro4-137/+106
combination of kern_path_parent() and lookup_create(). Does *not* expose struct nameidata to caller. Syscalls converted to that... Signed-off-by: Al Viro <viro@zeniv.linux.org.uk>
2011-07-20kill LOOKUP_CONTINUEAl Viro2-9/+3
LOOKUP_PARENT is equivalent to it now Signed-off-by: Al Viro <viro@zeniv.linux.org.uk>
2011-07-20nfs: LOOKUP_{OPEN,CREATE,EXCL} is set only on the last stepAl Viro1-4/+2
Signed-off-by: Al Viro <viro@zeniv.linux.org.uk>
2011-07-20cifs_lookup(): LOOKUP_OPEN is set only on the last componentAl Viro1-1/+1
Signed-off-by: Al Viro <viro@zeniv.linux.org.uk>
2011-07-20ceph: LOOKUP_OPEN is set only when it's the last componentAl Viro1-1/+0

2011-07-20jfs_ci_revalidate() is safe from RCU modeAl Viro1-2/+0
Signed-off-by: Al Viro <viro@zeniv.linux.org.uk>
2011-07-20LOOKUP_CREATE and LOOKUP_RENAME_TARGET can be set only on the last stepAl Viro3-12/+6
Signed-off-by: Al Viro <viro@zeniv.linux.org.uk>
2011-07-20no need to check for LOOKUP_OPEN in ->create() instancesAl Viro5-10/+10
... it will be set in nd->flag for all cases with non-NULL nd (i.e. when called from do_last()). Signed-off-by: Al Viro <viro@zeniv.linux.org.uk>
2011-07-20don't pass nameidata to vfs_create() from ecryptfs_create()Al Viro1-28/+5
Instead of playing with removal of LOOKUP_OPEN, mangling (and restoring) nd->path, just pass NULL to vfs_create(). The whole point of what's being done there is to suppress any attempts to open file by underlying fs, which is what nd == NULL indicates. Signed-off-by: Al Viro <viro@zeniv.linux.org.uk>
2011-07-20don't transliterate lower bits of ->intent.open.flags to FMODE_...Al Viro7-31/+24
->create() instances are much happier that way... Signed-off-by: Al Viro <viro@zeniv.linux.org.uk>
2011-07-20Don't pass nameidata when calling vfs_create() from mknod()Al Viro1-1/+1
All instances can cope with that now (and ceph one actually starts working properly). Signed-off-by: Al Viro <viro@zeniv.linux.org.uk>
2011-07-20fix mknod() on nfs4 (hopefully)Al Viro1-12/+12
a) check the right flags in ->create() (LOOKUP_OPEN, not LOOKUP_CREATE) b) default (!LOOKUP_OPEN) open_flags is O_CREAT|O_EXCL|FMODE_READ, not 0 c) lookup_instantiate_filp() should be done only with LOOKUP_OPEN; otherwise we need to issue CLOSE, lest we leak stateid on server. Signed-off-by: Al Viro <viro@zeniv.linux.org.uk>
2011-07-20nameidata_to_nfs_open_context() doesn't need nameidata, actually...Al Viro1-6/+7
just open flags; switched to passing just those and renamed to create_nfs_open_context() Signed-off-by: Al Viro <viro@zeniv.linux.org.uk>
2011-07-20nfs_open_context doesn't need struct path eitherAl Viro8-44/+42
just dentry, please... Signed-off-by: Al Viro <viro@zeniv.linux.org.uk>
2011-07-20nfs4_opendata doesn't need struct path eitherAl Viro1-23/+22
Signed-off-by: Al Viro <viro@zeniv.linux.org.uk>
2011-07-20nfs4_closedata doesn't need to mess with struct pathAl Viro3-22/+21
instead of path_get()/path_put(), we can just use nfs_sb_{,de}active() to pin the superblock down. Signed-off-by: Al Viro <viro@zeniv.linux.org.uk>
2011-07-20cifs: fix the type of cifs_demultiplex_thread()Al Viro1-2/+3
... and get rid of a bogus typecast, while we are at it; it's not just that we want a function returning int and not void, but cast to pointer to function taking void * and returning void would be (void (*)(void *)) and not (void *)(void *), TYVM... Signed-off-by: Al Viro <viro@zeniv.linux.org.uk>
2011-07-20ecryptfs_inode_permission() doesn't need to bail out on RCUAl Viro1-2/+0
... now that inode_permission() can take MAY_NOT_BLOCK and handle it properly. Signed-off-by: Al Viro <viro@zeniv.linux.org.uk>

2011-07-20no reason to keep exec_permission() separate nowAl Viro1-41/+4
cache footprint alone makes it a bad idea... Signed-off-by: Al Viro <viro@zeniv.linux.org.uk>

Signed-off-by: Al Viro <viro@zeniv.linux.org.uk>
2011-07-20->permission() sanitizing: don't pass flags to exec_permission()Al Viro3-27/+7
pass mask instead; kill security_inode_exec_permission() since we can use security_inode_permission() instead. Signed-off-by: Al Viro <viro@zeniv.linux.org.uk>
2011-07-20selinux: don't transliterate MAY_NOT_BLOCK to IPERM_FLAG_RCUAl Viro2-3/+3
Signed-off-by: Al Viro <viro@zeniv.linux.org.uk>
2011-07-20->permission() sanitizing: don't pass flags to ->inode_permission()Al Viro5-8/+13
pass that via mask instead. Signed-off-by: Al Viro <viro@zeniv.linux.org.uk>
2011-07-20->permission() sanitizing: don't pass flags to ->permission()Al Viro31-55/+55
not used by the instances anymore. Signed-off-by: Al Viro <viro@zeniv.linux.org.uk>
2011-07-20->permission() sanitizing: don't pass flags to generic_permission()Al Viro16-19/+18
redundant; all callers get it duplicated in mask & MAY_NOT_BLOCK and none of them removes that bit. Signed-off-by: Al Viro <viro@zeniv.linux.org.uk>
2011-07-20->permission() sanitizing: don't pass flags to ->check_acl()Al Viro28-32/+32

Duplicate the flags argument into mask bitmap. Signed-off-by: Al Viro <viro@zeniv.linux.org.uk>
2011-07-20kill check_acl callback of generic_permission()Al Viro20-37/+47
its value depends only on inode and does not change; we might as well store it in ->i_op->check_acl and be done with that. Signed-off-by: Al Viro <viro@zeniv.linux.org.uk>
