* core dump: user_regset writebackRoland McGrath2008-03-04
| | | | | | | | | | | | This makes the user_regset-based core dump code call user_regset writeback hooks when available. This is necessary groundwork to allow IA64 to set CORE_DUMP_USE_REGSET.

| | | | | | | | | | | | | | | | | | | | | | | | In commit e6bafba5b4765a5a252f1b8d31cbf6d2459da337, a bug was fixed that involved converting !x & y to !(x & y). The code below shows the same pattern, and thus should perhaps be fixed in the same way. This is not tested and clearly changes the semantics, so it is only something to consider.

| * Allow ARG_MAX execve string space even with a small stack limitLinus Torvalds2008-03-03
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The new code that removed the limitation on the execve string size (which was historically 32 pages) replaced it with a much softer limit based on RLIMIT_STACK which is usually much larger than the traditional limit. See commit b6a2fea39318e43fee84fa7b0b90d68bed92d2ba ("mm: variable length argument support") for details. However, if you have a small stack limit (perhaps because you need lots of stacks in a threaded environment), the new heuristic of allowing up to 1/4th of RLIMIT_STACK to be used for argument and environment strings could actually be smaller than the old limit. So just say that it's ok to have up to ARG_MAX strings regardless of the value of RLIMIT_STACK, and check the rlimit only when going over that traditional limit. (Of course, if you actually have a *really* small stack limit, the whole stack itself will be limited before you hit ARG_MAX, but that has always been true and is clearly the right behaviour anyway).

| * [XFS] If you mount an XFS filesystem with no mount options at all, thenJosef Jeff Sipek2008-02-28

This regression was introduced in 970451. With no mount options specified, xfs_parseargs() does the following: int ikeep = 0; args->flags |= XFSMNT_BARRIER; args->flags2 |= XFSMNT2_COMPAT_IOSIZE; if (!options) goto done; It only sets the above two options by default and before, it also used to set XFSMNT_IDELETE by default. If options are specified, then if (!(args->flags & XFSMNT_DMAPI) && !ikeep) args->flags |= XFSMNT_IDELETE; is executed later on which is skipped by the "goto done;" above. The solution is to invert the logic.

When writing to a file, ext4_get_block_wrap() is called with create=1 in order to request that blocks be allocated if necessary. It currently calls ext4_get_blocks() with create=0 in order to do a lookup first. If the inode contains an unitialized data block, the buffer head is left unampped, which ext4_get_blocks_wrap() returns, causing the BUG. We fix this by checking to see if the buffer head is unmapped, and if so, we make sure the the buffer head is mapped by calling ext4_ext_get_blocks with create=1.

Depending on the current process's pid, ext4_find_near() and ext4_ext_find_goal() can return a block number greater than the maximum blocks count in the filesystem and in that case the block will be not allocated in the same group as the inode.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | I added a nasty local variable shadowing bug to fuse in 2.6.24, with the result, that the 'default_permissions' mount option is basically ignored. How did this happen? - old err declaration in inner scope - new err getting declared in outer scope - 'return err' from inner scope getting removed - old declaration not being noticed -Wshadow would have saved us, but it doesn't seem practical for the kernel :( More testing would have also saved us :(( Signed-off-by: Miklos Szeredi <mszeredi@suse.cz> Cc: <stable@kernel.org> Signed-off-by: Andrew Morton <akpm@linux-foundation.org> Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>

| | * Wrap buffers used for rpc debug printks into RPC_IFDEBUGPavel Emelyanov2008-02-21
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Sorry for the noise, but here's the v3 of this compilation fix :) There are some places, which declare the char buf[...] on the stack to push it later into dprintk(). Since the dprintk sometimes (if the CONFIG_SYSCTL=n) becomes an empty do { } while (0) stub, these buffers cause gcc to produce appropriate warnings. Wrap these buffers with RPC_IFDEBUG macro, as Trond proposed, to compile them out when not needed. Signed-off-by: Pavel Emelyanov <xemul@openvz.org> Acked-by: J.

| | * NFS: flush signals before taking down callback threadJeff Layton2008-02-20

Peter Staubach noticed while testing that patch on an older kernel that he would occasionally see this printk in rpc_register fire: "RPC: failed to contact portmap (errno -512). The NFSv4 callback thread is signaled by nfs_callback_down(), but never flushes that signal. All of the shutdown processing is done with that signal pending. This makes it fail the call to unregister the port with the portmapper. In actuality, this rpc_register call isn't necessary at all since the port isn't actually registered with the portmapper anymore. Regardless, there doesn't seem to be any reason to leave the signal pending while the thread is being shut down and flushing it should generally silence that printk.

| * | Remove empty file remnants that were left in the tree by mistakeLinus Torvalds2008-02-20
| |/ | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Noted by various people (Sam, Jeff, Roland..) Commit 58b7983d15a422d9616bdc4e245d5c31dfaefbe2 intended to remove the xfs "Makefile-linux-2.6" file, but it was mistakenly still left in the tree as a empty file, and would cause git to correctly complain about a tracked file being removed after a "make distclean" (which removes empty files as garbage). And the asm-x86/desc_64.h file was supposed to be removed by commit c81c6ca45a69478c7877b729af1942d2b80ef582, but instead stayed around containing just a single newline. Get rid of them both properly. Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>

The patch minimally reverts us back to the 2.6.19 code for a 2.6.20 release. <-- snip --> It has since been dead code, and unless someone wants to revive it now it's time to remove it. This patch also makes bio_release_pages() static again and removes the ki_bio_count member from struct kiocb, reverting changes that had been done for this dead code.
