| * [patch 2/2] Use find_task_by_vpid in audit codePavel Emelyanov2008-04-281-3/+3
| | | | | | | | | | | | | | | | | | | | | | | | | | | | The pid to lookup a task by is passed inside audit code via netlink message. Thanks to Denis Lunev, netlink packets are now (since 2.6.24) _always_ processed in the context of the sending task. So this is correct to lookup the task with find_task_by_vpid() here.

| * [patch 1/2] audit: let userspace fully control TTY input auditingMiloslav Trmac2008-04-283-59/+5
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Remove the code that automatically disables TTY input auditing in processes that open TTYs when they have no other TTY open; this heuristic was intended to automatically handle daemons, but it has false positives (e.g. with sshd) that make it impossible to control TTY input auditing from a PAM module. With this patch, TTY input auditing is controlled from user-space only. On the other hand, not even for daemons does it make sense to audit "input" from PTY masters; this data was produced by a program writing to the PTY slave, and does not represent data entered by the user.

| * Audit: standardize string audit interfacesEric Paris2008-04-285-24/+29
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch standardized the string auditing interfaces. No userspace changes will be visible and this is all just cleanup and consistancy work. We have the following string audit interfaces to use: void audit_log_n_hex(struct audit_buffer *ab, const unsigned char *buf, size_t len); void audit_log_n_string(struct audit_buffer *ab, const char *buf, size_t n); void audit_log_string(struct audit_buffer *ab, const char *buf); void audit_log_n_untrustedstring(struct audit_buffer *ab, const char *string, size_t n); void audit_log_untrustedstring(struct audit_buffer *ab, const char *string); This may be the first step to possibly fixing some of the issues that people have with the string output from the kernel audit system. But we still don't have an agreed upon solution to that problem. Signed-off-by: Eric Paris <eparis@redhat.com> Signed-off-by: Al Viro <viro@zeniv.linux.org.uk>
| * Audit: stop deadlock from signals under loadEric Paris2008-04-281-5/+35
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | A deadlock is possible between kauditd and auditd under load if auditd receives a signal. When auditd receives a signal it sends a netlink message to the kernel asking for information about the sender of the signal. In that same context the audit system will attempt to send a netlink message back to the userspace auditd. If kauditd has already filled the socket buffer (see netlink_attachskb()) auditd will now put itself to sleep waiting for room to send the message. Since auditd is responsible for draining that socket we have a deadlock. The fix, since the response from the kernel does not need to be synchronous is to send the signal information back to auditd in a separate thread. And thus auditd can continue to drain the audit queue normally. Signed-off-by: Eric Paris <eparis@redhat.com> Signed-off-by: Al Viro <viro@zeniv.linux.org.uk>
| * Audit: save audit_backlog_limit audit messages in case auditd comes backEric Paris2008-04-281-21/+81
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch causes the kernel audit subsystem to store up to audit_backlog_limit messages for use by auditd if it ever appears sometime in the future in userspace. This is useful to collect audit messages during bootup and even when auditd is stopped. This is NOT a reliable mechanism, it does not ever call audit_panic, nor should it. audit_log_lost()/audit_panic() are called during the normal delivery mechanism. The messages are still sent to printk/syslog as usual and if too many messages appear to be queued they will be silently discarded. I liked doing it by default, but this patch only uses the queue in question if it was booted with audit=1 or if the kernel was built enabling audit by default.

This operation might be intend to guarantee that interrupts for the events newly occured during previous events are being handled will be successfully generated. But current implementaion has the following prolems. - Current interrupt service routin clears status changes without waiting command completion. Because of this, events might not be cleared properly. - Current interrupt service routine clears status changes caused by disabling or enabling hotplug interrupts itself. This will lose new events that occurs during previous interrupts are being handled. - Current implementation doesn't have any serialization mechanism between the code to wait for command completion and the interrupt handler that clears the command completion events caused by itself. There is clearly race conditions between them, and it may cause the problem that waiting for command completion doesn't work for example. To fix those problems, this patch stops disabling/re-enabling hotplug interrupts in interrupt service routine. Instead of this, this patch re-inspects Slot Status register after clearing what is presumed to be the last bending interrupt in order to guarantee that all interrupt events are serviced.

| * | PCI Express ASPM support should default to 'No'Jesper Juhl2008-04-231-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Running 'make oldconfig' I just noticed that PCIEASPM defaults to 'y' in Kconfig even though the feature is both experimental and the help text recommends that if you are unsure you say 'n'. It seems to me that this really should default to 'n', not 'y' at the moment. The following patch makes that change. Please consider applying.

* | | block: fix queue locking verificationLinus Torvalds2008-04-291-2/+8
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The new queue_flag_set/clear() functions verify that the queue is locked, but in doing so they will actually instead oops if the queue lock hasn't been initialized at all. So fix the lock debug test to consider the "no lock" case to be unlocked. This way you get a nice WARN_ON_ONCE() instead of a fatal oops. Bug introduced by commit 75ad23bc0fcb4f992a5d06982bf0857ab1738e9e ("block: make queue flags non-atomic").

This was a self-inflicted wound: I've not seen that happen with unhacked sources; but for debug reasons I'd changed my x86/Makefile to compile no-unit-at-a-time, and that in conjunction with OPTIMIZE_INLINING=y ended up with vget_cycles() in kernel text. Perhaps it can happen in other ways: safer to use __always_inline. Signed-off-by: Hugh Dickins <hugh@veritas.com> Signed-off-by: Ingo Molnar <mingo@elte.hu>
