* V4L/DVB (7768): reorganize some DVB-S Kconfig itemsMauro Carvalho Chehab2008-04-29
| | | | | | | There are some DVB-S tuners together with DVB-S tags, while others together with tuners. Better to have all of them together. Signed-off-by: Mauro Carvalho Chehab <mchehab@infradead.org>
* V4L/DVB(7767): Move tuners to common/tunersMauro Carvalho Chehab2008-04-29
| | | | | | | | | There were several issues in the past, caused by the hybrid tuner design, since now, the same tuner can be used by drivers/media/dvb and drivers/media/video. Kconfig items were rearranged, to split V4L/DVB core from their drivers. Signed-off-by: Mauro Carvalho Chehab <mchehab@infradead.org>

* V4L/DVB (7753): saa7134: fix tuner setupMauro Carvalho Chehab2008-04-29
| | | | | | | | | | | | | | | | | | | | | | Tuner setup were happening during i2c attach callback. This means that it would happen on two conditions: 1) if tuner module weren't load, it will happen at request_module("tuner"); 2) if tuner is not compiled as a module, or it is already loaded (for example, on setups with more than one tuner), it will happen when saa7134 registers I2C bus. Due to that, if tuner were loaded, tuner setup will happen _before_ reading the proper values at tuner eeprom. Since set_addr refuses to change for a tuner that were previously defined (except if the tuner_addr is set), this were making eeprom tuner detection useless. This patch removes tuner type setup from saa7134-i2c, moving it to the proper place, after taking eeprom into account.

| * [patch 1/2] audit: let userspace fully control TTY input auditingMiloslav Trmac2008-04-28
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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 Paris2008-04-28
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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 Paris2008-04-28
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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 Paris2008-04-28
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Current shpchp uses the combination of bus number and slot number as a slot name. But it is not a good idea because bus number is not a physical identifier but a logical identifier. This is against the shpc specification. So remove the bus number from the physical identifier. However, there are some platforms with the problem that it provides the same slot number. For those platforms, this patch also introduces new module option 'shpchp_slot_with_bus'. If it is specified, shpchp uses the combination of bus number and slot number as a slot name.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Clean up pciehp_ini(). This patch is trying to - Remove redundant capablity checks that were already done in PCIe port bus driver. - Separate the code only for debugging and make debug information easier to read. - Make the entire code easier to read and understand what it is doing.

| * | pciehp: Mask hotplug interrupt at controller releaseKenji Kaneshige2008-04-25
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | We must disable hotplug interrupt at controller relase time, otherwise spurious interrupts might happen if any slot events occured (e.g. MRL change) after unloading pciehp driver.

| * | pciehp: Remove useless hotplug interrupt enablingKenji Kaneshige2008-04-25
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Hotplug interrupt is enabled at initialization and nobody clears it. So we need to setup it in each command. This patch removes redundant codes about this.

| * | pciehp: Fix wrong slot capability checkKenji Kaneshige2008-04-25
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Current pciehp saves only 8bits of Slot Capability registers in ctrl->ctrlcap. But it refers more than 8bit for checking EMI capability. It is clearly a bug and EMI would never work. To fix this problem, this patch saves full Slot Capability contens in ctrl->slot_cap. It also reduce the redundant reads of Slot Capability register. And this pach also cleans up the macros to check the slot capabilitys (e.g. MRL_SENS(), and so on).

| * | pciehp: Fix wrong slot control register accessKenji Kaneshige2008-04-25
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Current pciehp implementaion clears hotplug events without waiting for command completion. Because of this, events might not be cleared properly. To prevent this problem, we must use pciehp_write_cmd() to write to Slot Control register.
