As of this kernel the AHCI driver grabs the controller and rams it into AHCI mode losing the PATA ports and making CD drives and the like vanish. The all-generic-ide option fails because the AHCI driver grabbed the PCI device and reconfigured it. To fix this three things are needed. #1 We must put the chip into dual function mode #2 The AHCI driver must grab only function 0 (already in your rc1 tree) #3 Something must grab the PATA ports The attached patch is the minimal risk edition of this. It puts the chip into dual function mode so that AHCI will grab the SATA ports without losing the PATA ports. To keep the risk as low as possible the third patch adds the PCI identifiers for the PATA port and the FN check to the ide-generic driver. There is a more featured jmicron driver on its way but that adds risk and the ide-generic support is sufficient to install and run a system. The actual chip setup done by the quirk is the precise setup recommended by the vendor. (The JMB368 appears only in the ide-generic entry as it has no AHCI so does not need the quirk) Signed-off-by: Alan Cox <alan@redhat.com> Acked-by: Jeff Garzik <jgarzik@pobox.com> Signed-off-by: Linus Torvalds <torvalds@osdl.org>

* | [PATCH] lockdep: annotate the sysfs i_mutex to be a separate classArjan van de Ven2006-07-12
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | sysfs has a different i_mutex lock order behavior for i_mutex than the other filesystems; sysfs i_mutex is called in many places with subsystem locks held. At the same time, many of the VFS locking rules do not apply to sysfs at all (cross directory rename for example). To untangle this mess (which gives false positives in lockdep), we're giving sysfs inodes their own class for i_mutex.

* | [PATCH] Fix prctl privilege escalation and suid_dumpable (CVE-2006-2451)Marcel Holtmann2006-07-12
|/ | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Based on a patch from Ernie Petrides During security research, Red Hat discovered a behavioral flaw in core dump handling. A local user could create a program that would cause a core file to be dumped into a directory they would not normally have permissions to write to. This could lead to a denial of service (disk consumption), or allow the local user to gain root privileges. The prctl() system call should never allow to set "dumpable" to the value 2. Especially not for non-privileged users. This can be split into three cases: 1) running as root -- then core dumps will already be done as root, and so prctl(PR_SET_DUMPABLE, 2) is not useful 2) running as non-root w/setuid-to-root -- this is the debatable case 3) running as non-root w/setuid-to-non-root -- then you definitely do NOT want "dumpable" to get set to 2 because you have the privilege escalation vulnerability With case #2, the only potential usefulness is for a program that has designed to run with higher privilege (than the user invoking it) that wants to be able to create root-owned root-validated core dumps. This might be useful as a debugging aid, but would only be safe if the program had done a chdir() to a safe directory. There is no benefit to a production setuid-to-root utility, because it shouldn't be dumping core in the first place. If this is true, then the same debugging aid could also be accomplished with the "suid_dumpable" sysctl.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 1. Multipath devices for which SetPGID is not supported are not handled well. Use NOP ccws for path verification (sans path grouping) when SetPGID is not supported. 2. Check for PGIDs already set with SensePGID on _all_ paths (not just the first one) and try to find a common one. Moan if no common PGID can be found (and use NOP verification). If no PGIDs have been set, use the css global PGID (as before). (Rationale: SetPGID will get a command reject if the PGID it tries to set does not match the already set PGID.) 3. Immediately before reboot, issue RESET CHANNEL PATH (rcp) on all chpids. This will remove the old PGIDs. rcp will generate solicited CRWs which can be savely ignored by the machine check handler (all other actions create unsolicited CRWs).

Original report by Alessio Sangalli, lspci debugging help by Pekka Enberg, and trial patch suggested by Daniel Ritz: "From the docs available i would _guess_ this thing is really similar to the 82443BX/82371AB combination. at least the SMBus base address register is hidden at the very same place (32bit at 0x90 in function 3 of the "south" brigde)" The dang thing is largely undocumented, but the patch was corroborated by Asit Mallick: "I am trying to find the register information. 440MX is an integration of 440BX north-bridge without AGP and PIIX4E (82371EB). PIIX4 quirk should cover the ACPI and SMBus related I/O registers." and verified to fix the problem by Alessio.

While setting (system_state != SYSTEM_RUNNING) on resume seemed more general, Andrew Morton preferred this approach. http://bugzilla.kernel.org/show_bug.cgi?id=3469 Make acpi_os_allocate() into an inline function to allow /proc/slab_allocators to work. Delete some memset() that could fault on allocation failure. Signed-off-by: Len Brown <len.brown@intel.com>

Some of the debug data structures are packed by default to minimize size. Added an error message for the case where acpi_os_get_thread_id() returns zero. A non-zero value is required by the core ACPICA code to ensure the proper operation of AML mutexes and recursive control methods. The DSDT is now the only ACPI table that determines whether the AML interpreter is in 32-bit or 64-bit mode. Not really a functional change, but the hooks for per-table 32/64 switching have been removed from the code. A clarification to the ACPI specification is forthcoming in ACPI 3.0B. Fixed a possible leak of an Owner ID in the error path of tbinstal.c acpi_tb_init_table_descriptor() and migrated all table OwnerID deletion to a single place in acpi_tb_uninstall_table() to correct possible leaks when using the acpi_tb_delete_tables_by_type() interface (with assistance from Lance Ortiz.) Fixed a problem with Serialized control methods where the semaphore associated with the method could be over-signaled after multiple method invocations. Fixed two issues with the locking of the internal namespace data structure. Both the Unload() operator and acpi_unload_table() interface now lock the namespace during the namespace deletion associated with the table unload (with assistance from Linn Crosetto.) Fixed problem reports (Valery Podrezov) integrated: - Eliminate unnecessary memory allocation for CreateXxxxField http://bugzilla.kernel.org/show_bug.cgi?id=5426 Fixed problem reports (Fiodor Suietov) integrated: - Incomplete cleanup branches in AcpiTbGetTableRsdt (BZ 369) - On Address Space handler deletion, needless deactivation call (BZ 374) - AcpiRemoveAddressSpaceHandler: validate Device handle parameter (BZ 375) - Possible memory leak, Notify sub-objects of Processor, Power, ThermalZone (BZ 376) - AcpiRemoveAddressSpaceHandler: validate Handler parameter (BZ 378) - Minimum Length of RSDT should be validated (BZ 379) - AcpiRemoveNotifyHandler: return AE_NOT_EXIST if Processor Obj has no Handler (BZ (380) - AcpiUnloadTable: return AE_NOT_EXIST if no table of specified type loaded (BZ 381) Signed-off-by: Bob Moore <robert.moore@intel.com> Signed-off-by: Len Brown <len.brown@intel.com>

But the AML mutexes in exmutex.c expect a unique non-zero number for each thread - as they track this thread_id to permit the mutex re-entrancy defined by the ACPI spec. http://bugzilla.kernel.org/show_bug.cgi?id=6687 Signed-off-by: Len Brown <len.brown@intel.com>
