struct pagemap_walk was placed on stack, some hooks are initialized, the rest (->pgd_entry, ->pud_entry, ->pte_entry) are valid but junk.

2008-07-22execve filename: document and export via auxiliary vectorJohn Reiser1-0/+1
The Linux kernel puts the filename argument of execve() into the new address space. Many developers are surprised to learn this. Those who know and could use it, object "But it's not documented." Those who want to use it dislike the expression (char *)(1+ strlen(env[-1+ n_env]) + env[-1+ n_env]) because it requires locating the last original environment variable, and assumes that the filename follows the characters. This patch documents the insertion of the filename, and makes it easier to find by adding a new tag AT_EXECFN in the ElfXX_auxv_t; see <elf.h>. In many cases readlink("/proc/self/exe",) gives the same answer. But if all the original pages get unmapped, then the kernel erases the symlink for /proc/self/exe. This can happen when a program decompressor does a good job of cleaning up after uncompressing directly to memory, so that the address space of the target program looks the same as if compression had never happened. One example is http://upx.sourceforge.net . One notable use of the underlying concept (what path containED the executable) is glibc expanding $ORIGIN in DT_RUNPATH. In practice for the near term, it may be a good idea for user-mode code to use both /proc/self/exe and AT_EXECFN as fall-back methods for each other. /proc/self/exe can fail due to unmapping, AT_EXECFN can fail because it won't be present on non-new systems. The auxvec or {AT_EXECFN}.d_val also can get overwritten, although in nearly all cases this would be the result of a bug. The runtime cost is one NEW_AUX_ENT using two words of stack space. The underlying value is maintained already as bprm->exec; setup_arg_pages() in fs/exec.c slides it for stack_shift, etc. Signed-off-by: John Reiser <jreiser@BitWagon.com> Cc: Roland McGrath <roland@redhat.com> Cc: Jakub Jelinek <jakub@redhat.com> Cc: Ulrich Drepper <drepper@redhat.com> Cc: Benjamin Herrenschmidt <benh@kernel.crashing.org> Signed-off-by: Andrew Morton <akpm@linux-foundation.org> Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>

Move the line disciplines towards a conventional ->ops arrangement. For the moment the actual 'tty_ldisc' struct in the tty is kept as part of the tty struct but this can then be changed if it turns out that when it all settles down we want to refcount ldiscs separately to the tty.

2008-07-17configfs: Allow ->make_item() and ->make_group() to return detailed errors.Joel Becker4-33/+26
The configfs operations ->make_item() and ->make_group() currently return a new item/group. A return of NULL signifies an error. Because of this, -ENOMEM is the only return code bubbled up the stack. Multiple folks have requested the ability to return specific error codes when these operations fail. This patch adds that ability by changing the ->make_item/group() ops to return ERR_PTR() values. These errors are bubbled up appropriately. NULL returns are changed to -ENOMEM for compatibility. Also updated are the in-kernel users of configfs. This is a rework of reverted commit 11c3b79218390a139f2d474ee1e983a672d5839a. Signed-off-by: Joel Becker <joel.becker@oracle.com>

2008-07-16[PATCH] ocfs2: fix oops in mmap_truncate testingColy Li1-3/+10
This patch fixes a mmap_truncate bug which was found by ocfs2 test suite. In an ocfs2 cluster more than 1 node, run program mmap_truncate, which races mmap writes and truncates from multiple processes. While the test is running, a stat from another node forces writeout, causing an oops in ocfs2_get_block() because it sees a buffer to write which isn't allocated. This patch fixed the bug by clear dirty and uptodate bits in buffer, leave the buffer unmapped and return. Fix is suggested by Mark Fasheh, and I code up the patch.

All dentry-related operations are already BKL-safe, since they are protected by the VFS locking. No extra locks should be needed in the NFS code. In the case of nfs_revalidate_inode(), we're only doing an attribute update (protected by the inode->i_lock). In the case of nfs_lookup(), we're instantiating a new dentry, so there should be no contention possible until after we call d_materialise_unique.

Make an NFS-private version of vmtruncate that has the necessary locking semantics.

If the conflicting lock is (0, 4095) the F_GETLK request for (1024, 10) returns (0, 1), which doesn't even cover the requested range, and is quite confusing.
