[PATCH] kernel/params.c: fix sysfs access with CONFIG_MODULES=n

2005-12-27T00:08:58Z

All the work was done to setup the file and maintain the file handles but the access functions were zeroed out due to the #ifdef. Removing the #ifdef allows full access to all the parameters when CONFIG_MODULES=n. akpm: put it back again, but use CONFIG_SYSFS instead. This patch has already been included in Linus' tree.

[PATCH] Add try_to_freeze to kauditd

2005-12-14T23:43:00Z

kauditd was causing suspends to fail because it refused to freeze. Adding a try_to_freeze() to its sleep loop solves the issue. Signed-off-by: Pierre Ossman Acked-by: Pavel Machek Cc: David Woodhouse Signed-off-by: Andrew Morton Signed-off-by: Linus Torvalds Signed-off-by: Greg Kroah-Hartman

[PATCH] Fix crash when ptrace poking hugepage areas

2005-12-14T23:42:54Z

set_page_dirty() will not cope with being handed a page * which is part of a compound page, but not the master page in that compound page. This case can occur via access_process_vm() if you attemp to write to another process's hugepage memory area using ptrace() (causing an oops or hang). This patch fixes the bug by only calling set_page_dirty() from access_process_vm() if the page is not a compound page. We already use a similar fix in bio_set_pages_dirty() for the case of direct io to hugepages.

[PATCH] Don't auto-reap traced children

2005-11-24T22:10:07Z

If a task is being traced we never auto-reap it even if it might look like its parent doesn't care. The tracer obviously _does_ care. Signed-off-by: Linus Torvalds Signed-off-by: Chris Wright Signed-off-by: Greg Kroah-Hartman

[PATCH] Fix ptrace self-attach rule

2005-11-11T05:22:08Z

Before we did CLONE_THREAD, the way to check whether we were attaching to ourselves was to just check "current == task", but with CLONE_THREAD we should check that the thread group ID matches instead. Signed-off-by: Linus Torvalds

[PATCH] - fix signal->live leak in copy_process()

2005-11-11T05:18:55Z

exit_signal() (called from copy_process's error path) should decrement ->signal->live, otherwise forking process will miss 'group_dead' in do_exit(). Signed-off-by: Oleg Nesterov Signed-off-by: Chris Wright Signed-off-by: Greg Kroah-Hartman

[PATCH] CVE-2005-2709 sysctl unregistration oops

2005-11-08T19:14:00Z

You could open the /proc/sys/net/ipv4/conf// file, then wait for interface to go away, try to grab as much memory as possible in hope to hit the (kfreed) ctl_table. Then fill it with pointers to your function. Then do read from file you've opened and if you are lucky, you'll get it called as ->proc_handler() in kernel mode. So this is at least an Oops and possibly more. It does depend on an interface going away though, so less of a security risk than it would otherwise be. Signed-off-by: Greg Kroah-Hartman

[PATCH] Yet more posix-cpu-timer fixes

2005-10-27T16:08:43Z

This just makes sure that a thread's expiry times can't get reset after it clears them in do_exit. This is what allowed us to re-introduce the stricter BUG_ON() check in a362f463a6d316d14daed0f817e151835ce97ff7. Signed-off-by: Linus Torvalds

Revert "remove false BUG_ON() from run_posix_cpu_timers()"

2005-10-27T16:07:33Z

This reverts commit 3de463c7d9d58f8cf3395268230cb20a4c15bffa. Roland has another patch that allows us to leave the BUG_ON() in place by just making sure that the condition it tests for really is always true. That goes in next. Signed-off-by: Linus Torvalds

[PATCH] Fix cpu timers expiration time

2005-10-26T22:21:14Z

There's a silly off-by-one error in the code that updates the expiration of posix CPU timers, causing them to not be properly updated when they hit exactly on their expiration time (which should be the normal case). This causes them to then fire immediately again, and only _then_ get properly updated. Signed-off-by: Linus Torvalds
