* [SCSI] bnx2i: Fixed kernel panic caused by unprotected task->sc->request derefEddie Wai2011-12-14
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | During session recovery, the conn_stop call will trigger a flush to all outstanding SCSI cmds in the xmit queue. This will set all outstanding task->sc to NULL prior to the session_teardown call which frees the task memory. In the bnx2i SCSI response processing path, only the task was being checked for NULL under the session lock before the task->sc->request dereferencing. If there are outstanding SCSI cmd responses pending for process, the following kernel panic can be exposed where task->sc was found to be NULL.

* [SCSI] zfcp: return early from slave_destroy if slave_alloc returned earlySteffen Maier2011-12-14
| | | | | | | | | | | | | | | | | | | zfcp_scsi_slave_destroy erroneously always tried to finish its task even if the corresponding previous zfcp_scsi_slave_alloc returned early. This can lead to kernel page faults on accessing uninitialized fields of struct zfcp_scsi_dev in zfcp_erp_lun_shutdown_wait. Take the port field of the struct to determine if slave_alloc returned early. This zfcp bug is exposed by 4e6c82b (in turn fixing f7c9c6b to be compatible with 21208ae) which can call slave_destroy for a corresponding previous slave_alloc that did not finish. This patch is based on James Bottomley's fix suggestion in http://www.spinics.net/lists/linux-scsi/msg55449.html.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Prior to commit eaf35b1, cifs_save_resume_key had some NULL pointer checks at the top. It turns out that at least one of those NULL pointer checks is needed after all. When the LastNameOffset in a FIND reply appears to be beyond the end of the buffer, CIFSFindFirst and CIFSFindNext will set srch_inf.last_entry to NULL. Since eaf35b1, the code will now oops in this situation. Fix this by having the callers check for a NULL last entry pointer before calling cifs_save_resume_key. No change is needed for the call site in cifs_readdir as it's not reachable with a NULL current_entry pointer.

On CONFIG_X86_32 this is invalid, resulting in the following oops on some machines: BUG: unable to handle kernel paging request at f7f22280 IP: [<c10257b9>] reserve_ram_pages_type+0x89/0x210 [...] Call Trace: [<c104f8ca>] ? page_is_ram+0x1a/0x40 [<c1025aff>] reserve_memtype+0xdf/0x2f0 [<c1024dc9>] set_memory_uc+0x49/0xa0 [<c19334d0>] efi_enter_virtual_mode+0x1c2/0x3aa [<c19216d4>] start_kernel+0x291/0x2f2 [<c19211c7>] ? loglevel+0x1b/0x1b [<c19210bf>] i386_start_kernel+0xbf/0xc8 A better approach to this problem is to map the memory region with the correct attributes from the start, instead of modifying it after the fact. The uncached case can be handled by ioremap_nocache() and the cached by ioremap_cache(). Despite first impressions, it's not possible to use ioremap_cache() to map all cached memory regions on CONFIG_X86_64 because EFI_RUNTIME_SERVICES_DATA regions really don't like being mapped into the vmalloc space, as detailed in the following bug report, https://bugzilla.redhat.com/show_bug.cgi?id=748516 Therefore, we need to ensure that any EFI_RUNTIME_SERVICES_DATA regions are covered by the direct kernel mapping table on CONFIG_X86_64. To accomplish this we now map E820_RESERVED_EFI regions via the direct kernel mapping with the initial call to init_memory_mapping() in setup_arch(), whereas previously these regions wouldn't be mapped if they were after the last E820_RAM region until efi_ioremap() was called. Doing it this way allows us to delete efi_ioremap() completely. Signed-off-by: Matt Fleming <matt.fleming@intel.com> Cc: H.

| * | x86, hpet: Immediately disable HPET timer 1 if rtc irq is maskedMark Langsdorf2011-12-08
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | When HPET is operating in RTC mode, the TN_ENABLE bit on timer1 controls whether the HPET or the RTC delivers interrupts to irq8. When the system goes into suspend, the RTC driver sends a signal to the HPET driver so that the HPET releases control of irq8, allowing the RTC to wake the system from suspend. The switchover is accomplished by a write to the HPET configuration registers which currently only occurs while servicing the HPET interrupt. On some systems, I have seen the system suspend before an HPET interrupt occurs, preventing the write to the HPET configuration register and leaving the HPET in control of the irq8. As the HPET is not active during suspend, it does not generate a wake signal and RTC alarms do not work. This patch forces the HPET driver to immediately transfer control of the irq8 channel to the RTC instead of waiting until the next interrupt event.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | If we select a symbol it should have a type declared first otherwise in some situations the config tools get upset. They are currently perhaps a bit too resilient which is why this wasn't noticed initially.

| * | x86/intel_mid: Fix the Kconfig for MID selectionAlan Cox2011-12-06
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | We currently fail to build on CONFIG_X86_INTEL_MID=y and CONFIG_X86_MRST unset. We could build all the bits to make generic MID work if you picked MID platform alone but that's really silly. Instead use select and two variables. This looks a bit daft right now but once we add a Medfield selection it'll start to look a good deal more sensible.
