2006-07-02[JFFS2][XATTR] Fix memory leak in POSIX-ACL supportKaiGai Kohei
jffs2_clear_acl() which releases acl caches allocated by kmalloc() was defined but it was never called. Thus, we faced to the risk of memory leaking. This patch plugs jffs2_clear_acl() into jffs2_do_clear_inode(). It ensures to release acl cache when inode is cleared.

2006-06-29[JFFS2][XATTR] Fix xd->refcnt race conditionKaiGai Kohei
When xd->refcnt is checked whether this xdatum should be released or not, atomic_dec_and_lock() is used to ensure holding the c->erase_completion_lock. This fix change a specification of delete_xattr_datum(). Previously, it's only called when xd->refcnt equals zero. (calling it with positive xd->refcnt cause a BUG()) If you applied this patch, the function checks whether xd->refcnt is zero or not under the spinlock if necessary. Then, it marks xd DEAD flahs and links with xattr_dead_list or releases it immediately when xd->refcnt become zero.

2006-06-27[PATCH] vdso: randomize the i386 vDSO by moving it into a vmaIngo Molnar
Move the i386 VDSO down into a vma and thus randomize it. Besides the security implications, this feature also helps debuggers, which can COW a vma-backed VDSO just like a normal DSO and can thus do single-stepping and other debugging features. It's good for hypervisors (Xen, VMWare) too, which typically live in the same high-mapped address space as the VDSO, hence whenever the VDSO is used, they get lots of guest pagefaults and have to fix such guest accesses up - which slows things down instead of speeding things up (the primary purpose of the VDSO). There's a new CONFIG_COMPAT_VDSO (default=y) option, which provides support for older glibcs that still rely on a prelinked high-mapped VDSO. Newer distributions (using glibc 2.3.3 or later) can turn this option off. Turning it off is also recommended for security reasons: attackers cannot use the predictable high-mapped VDSO page as syscall trampoline anymore. There is a new vdso=[0|1] boot option as well, and a runtime /proc/sys/vm/vdso_enabled sysctl switch, that allows the VDSO to be turned on/off. (This version of the VDSO-randomization patch also has working ELF coredumping, the previous patch crashed in the coredumping code.) This code is a combined work of the exec-shield VDSO randomization code and Gerd Hoffmann's hypervisor-centric VDSO patch. Rusty Russell started this patch and i completed it.

2006-06-27[PATCH] fix static linking of NFSDavid Brownell
Builds on ARM report link problems with common configurations like statically linked NFS (for nfsroot). The symptom is that __init section code references __exit section code; that won't work since the exit sections are discarded (since they can never be called). The best fix for these particular cases would be an "__init_or_exit" section annotation.

In jffs2_release_xattr_datum(), it refers xd->refcnt to ensure whether releasing xd is allowed or not. But we can't hold xattr_sem since this function is called under spin_lock(&c->erase_completion_lock). Thus we have to refer it without any locking. This patch redefine xd->refcnt as atomic_t.
