NET: Fix sock_attach_fd() failure in sys_accept()

2007-04-06T10:43:14+00:00

[NET]: Correct accept(2) recovery after sock_attach_fd()

* d_alloc() in sock_attach_fd() fails leaving ->f_dentry of new file NULL
* bail out to out_fd label, doing fput()/__fput() on new file
* but __fput() assumes valid ->f_dentry and dereferences it

[PATCH] net: don't insert socket dentries into dentry_hashtable

2006-12-07T16:39:41+00:00

We currently insert socket dentries into the global dentry hashtable.  This
is suboptimal because there is currently no way these entries can be used
for a lookup().  (/proc/xxx/fd/xxx uses a different mechanism).  Inserting
them in dentry hashtable slows dcache lookups.

To let __dpath() still work correctly (ie not adding a " (deleted)") after
dentry name, we do :

- Right after d_alloc(), pretend they are hashed by clearing the
  DCACHE_UNHASHED bit.

- Call d_instantiate() instead of d_add() : dentry is not inserted in
  hash table.

  __dpath() & friends work as intended during dentry lifetime.

- At dismantle time, once dput() must clear the dentry, setting again
  DCACHE_UNHASHED bit inside the custom d_delete() function provided by
  socket code, so that dput() can just kill_it.

[PATCH] slab: remove kmem_cache_t

2006-12-07T16:39:25+00:00

Replace all uses of kmem_cache_t with struct kmem_cache.

The patch was generated using the following script:

	#!/bin/sh
	#
	# Replace one string by another in all the kernel sources.
	#

	set -e

	for file in `find * -name "*.c" -o -name "*.h"|xargs grep -l $1`; do
		quilt add $file
		sed -e "1,\$s/$1/$2/g" $file >/tmp/$$
		mv /tmp/$$ $file
		quilt refresh
	done

The script was run like this

	sh replace kmem_cache_t "struct kmem_cache"

[PATCH] file: modify struct fown_struct to use a struct pid

2006-10-02T14:57:14+00:00

File handles can be requested to send sigio and sigurg to processes.  By
tracking the destination processes using struct pid instead of pid_t we make
the interface safe from all potential pid wrap around problems.

[PATCH] Vectorize aio_read/aio_write fileop methods

2006-10-01T07:39:28+00:00

This patch vectorizes aio_read() and aio_write() methods to prepare for
collapsing all aio & vectored operations into one interface - which is
aio_read()/aio_write().
