* udf: Remove checking of existence of filename in udf_add_entry()Jan Kara2008-04-17
| | | | | | | | We don't have to check whether a directory entry already exists in a directory when creating a new one since we've already checked that earlier by lookup and we are holding directory i_mutex all the time. Signed-off-by: Jan Kara <jack@suse.cz>

| | | | | | | | | | | | | | | | | | | | | | | | | | The bus management workqueue job was in danger to dereference NULL pointers. Also, after having temporarily lifted card->lock, a few node pointers and a device pointer may have become invalid. Add NULL pointer checks and get the necessary references.

* | [PATCH] drop EOE records from printkSteve Grubb2008-03-01
| | | | | | | | | | | | | | | | | | | | | | | | Hi, While we are looking at the printk issue, I see that its printk'ing the EOE (end of event) records which is really not something that we need in syslog. Its really intended for the realtime audit event stream handled by the audit daemon. So, lets avoid printk'ing that record type.

* | [RFC] AUDIT: do not panic when printk loses messagesEric Paris2008-03-01
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | On the latest kernels if one was to load about 15 rules, set the failure state to panic, and then run service auditd stop the kernel will panic. This is because auditd stops, then the script deletes all of the rules. These deletions are sent as audit messages out of the printk kernel interface which is already known to be lossy. These will overun the default kernel rate limiting (10 really fast messages) and will call audit_panic(). The same effect can happen if a slew of avc's come through while auditd is stopped. This can be fixed a number of ways but this patch fixes the problem by just not panicing if auditd is not running. We know printk is lossy and if the user chooses to set the failure mode to panic and tries to use printk we can't make any promises no matter how hard we try, so why try? At least in this way we continue to get lost message accounting and will eventually know that things went bad. The other change is to add a new call to audit_log_lost() if auditd disappears. We already pulled the skb off the queue and couldn't send it so that message is lost. At least this way we will account for the last message and panic if the machine is configured to panic. This code path should only be run if auditd dies for unforeseen reasons. If auditd closes correctly audit_pid will get set to 0 and we won't walk this code path.

| * | [ARM] 4837/1: make __get_unaligned_*() return unsigned typesLennert Buytenhek2008-02-29
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Eric Sandeen tracked an XFS on ARM corruption bug down to a function under fs/xfs/ involving some get_unaligned() calls on u64 pointers. As it turns out, calling ARM's get_unaligned() on a u64 pointer pointing to the following byte sequence: 80 81 82 83 84 85 86 87 would return ffffffff83828180 (LE mode.) This turns out to be because of implicit u8 -> int promotion in ARM's implementation of various helpers for get_unaligned(), causing them to accidentally return signed instead of unsigned values, which in turn caused the subsequent casts to unsigned long long in __get_unaligned_8_[bl]e() to sign-extend the lower words. Fix by casting the return values of __get_unaligned_[24]_[bl]e() to unsigned int.

So, either this macro should be defined always, or another > macro should be used, or ATAGS_PROC should depend on KEXEC. As the procfs export of ATAGS is not meant as a stable, general purpose ABI it shouldn't be an independent, general configuration option.

* | | rcupreempt: remove never-migrates assumption from rcu_process_callbacks()Paul E. McKenney2008-02-29
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch fixes a potentially invalid access to a per-CPU variable in rcu_process_callbacks(). This per-CPU access needs to be done in such a way as to guarantee that the code using it cannot move to some other CPU before all uses of the value accessed have completed. Even though this code is currently only invoked from softirq context, which currrently cannot migrate to some other CPU, life would be better if this code did not silently make such an assumption.

* | | rcupreempt: fix hibernate/resume in presence of PREEMPT_RCU and hotplugPaul E. McKenney2008-02-29
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This fixes a oops encountered when doing hibernate/resume in presence of PREEMPT_RCU. The problem was that the code failed to disable preemption when accessing a per-CPU variable. This is OK when called from code that already has preemption disabled, but such is not the case from the suspend/resume code path.

The idle CPU will not progress the RCU through its grace period and a synchronize_rcu my get stuck. Without this patch I have a box that will not boot when PREEMPT_RCU and NO_HZ are set. That same box boots fine with this patch. This patch comes from the -rt kernel where it has been tested for several months. Signed-off-by: Steven Rostedt <srostedt@redhat.com> Signed-off-by: Paul E.
