UBUNTU: SAUCE: (noup) megaraid_sas: Don't issue kill adapter for MFI controllers in case of PD list DCMD failure BugLink: http://bugs.launchpad.net/bugs/1552903 http://marc.info/?l=linux-scsi&m=145760492231010&w=2 There are few MFI adapters which do not support MR_DCMD_PD_LIST_QUERY so if MFI adapters fail this DCMD, it should not be considered as FATAL and driver should not issue kill adapter and set per controller's instance variable- pd_list_not_supported so that same variable can be used inside functions- slave_alloc and slave_configure to allow firmware scan. Killing adapter because of DCMD failure when this DCMD is not supported causes driver's probe getting failed. This issue got introduced because of below commit when MFI IO timeout handling was introduced- 6d40afbc megaraid_sas: MFI IO timeout handling Killing adapter in case of this DCMD failure should be limited to Fusion adapters only. Per controller's instance variable allow_fw_scan is removed as pd_list_not_supported better reflect the purpose. Signed-off-by:

BugLink: http://bugs.launchpad.net/bugs/1555765 Currently we use printk message to notify the throttle event. But this can flood the console if the cpu is throttled frequently. So replace the printk with the tracepoint to notify the throttle event. And also events like throttle below nominal frequency and OCC_RESET are reduced to pr_warn/pr_warn_once as pointed by MFG to not mark them as critical messages. This patch adds 'throttle_reason' to struct chip to store the throttle reason. Signed-off-by:

BugLink: http://bugs.launchpad.net/bugs/1555765 cpu_to_chip_id() does a DT walk through to find out the chip id by taking a contended device tree lock. This adds an unnecessary overhead in a hot path. So instead of calling cpu_to_chip_id() everytime cache the chip ids for all cores in the array 'core_to_chip_map' and use it in the hotpath.

BugLink: http://bugs.launchpad.net/bugs/1555338 Ben Hawkes says: In the mark_source_chains function (net/ipv4/netfilter/ip_tables.c) it is possible for a user-supplied ipt_entry structure to have a large next_offset field. This field is not bounds checked prior to writing a counter value at the supplied offset. Problem is that xt_entry_foreach() macro stops iterating once e->next_offset is out of bounds, assuming this is the last entry. With malformed data thats not necessarily the case so we can write outside of allocated area later as we might not have walked the entire blob. Fix this by simplifying mark_source_chains -- it already has to check if nextoff is in range to catch invalid jumps, so just do the check when we move to a next entry as well. Also, check that the offset meets the xtables_entry alignment. Reported-by:

BugLink: http://bugs.launchpad.net/bugs/1555640 For CONFIG_KALLSYMS, we keep two symbol tables and two string tables. There's one full copy, marked SHF_ALLOC and laid out at the end of the module's init section. There's also a cut-down version that only contains core symbols and strings, and lives in the module's core section. After module init (and before we free the module memory), we switch the mod->symtab, mod->num_symtab and mod->strtab to point to the core versions. We do this under the module_mutex. However, kallsyms doesn't take the module_mutex: it uses preempt_disable() and rcu tricks to walk through the modules, because it's used in the oops path. It's also used in /proc/kallsyms. There's nothing atomic about the change of these variables, so we can get the old (larger!) num_symtab and the new symtab pointer; in fact this is what I saw when trying to reproduce. By grouping these variables together, we can use a carefully-dereferenced pointer to ensure we always get one or the other (the free of the module init section is already done in an RCU callback, so that's safe). We allocate the init one at the end of the module init section, and keep the core one inside the struct module itself (it could also have been allocated at the end of the module core, but that's probably overkill).

In current scache init cache line_size is determined from cpu config register, however if there there no scache then mips_sc_probe_cm3 function populates a invalid line_size of 2. The invalid line_size can cause a NULL pointer deference during r4k_dma_cache_inv as r4k_blast_scache is populated based on line_size. Scache line_size of 2 is invalid option in r4k_blast_scache_setup. This issue was faced during a MIPS I6400 based virtual platform bring up where scache was not available in virtual platform model.

BugLink: http://bugs.launchpad.net/bugs/1555640 commit d144dfea upstream. If we use USB ID pin as wakeup source, and there is a USB block device on this USB OTG (ID) cable, the system will be deadlock after system resume. The root cause for this problem is: the workqueue ci_otg may try to remove hcd before the driver resume has finished, and hcd will disconnect the device on it, then, it will call device_release_driver, and holds the device lock "dev->mutex", but it is never unlocked since it waits workqueue writeback to run to flush the block information, but the workqueue writeback is freezable, it is not thawed before driver resume has finished. When the driver (device: sd 0:0:0:0:) resume goes to dpm_complete, it tries to get its device lock "dev->mutex", but it can't get it forever, then the deadlock occurs. Below call stacks show the situation. So, in order to fix this problem, we need to change workqueue ci_otg as freezable, then the work item in this workqueue will be run after driver's resume, this workqueue will not be blocked forever like above case since the workqueue writeback has been thawed too. Tested at: i.mx6qdl-sabresd and i.mx6sx-sdb.

BugLink: http://bugs.launchpad.net/bugs/1555640 commit 3a72494a upstream. The timer user status compat ioctl returned the bogus struct used for 64bit architectures instead of the 32bit one. This patch addresses it to return the proper struct. Signed-off-by:

BugLink: http://bugs.launchpad.net/bugs/1555640 commit c1099c32 upstream. HDSPM driver contains a code issuing zero-division potentially in system sample rate ctl code. This patch fixes it by not processing a zero or invalid rate value as a divisor, as well as excluding the invalid value to be passed via the given ctl element. Signed-off-by:

BugLink: http://bugs.launchpad.net/bugs/1555640 commit 197b958c upstream. The OSS sequencer client tries to drain the pending events at releasing. Unfortunately, as spotted by syzkaller fuzzer, this may lead to an unkillable process state when the event has been queued at the far future. Since the process being released can't be signaled any longer, it remains and waits for the echo-back event in that far future. Back to history, the draining feature was implemented at the time we misinterpreted POSIX definition for blocking file operation. Actually, such a behavior is superfluous at release, and we should just release the device as is instead of keeping it up forever. This patch just removes the draining call that may block the release for too long time unexpectedly.

BugLink: http://bugs.launchpad.net/bugs/1555640 commit 513ace79 upstream. X32 ABI uses the 64bit timespec in addition to 64bit alignment of 64bit values. This leads to incompatibilities in some PCM ioctls involved with snd_pcm_channel_info, snd_pcm_status and snd_pcm_sync_ptr structs. Fix the PCM compat ABI for these ioctls like the previous commit for ctl API. Reported-by:

BugLink: http://bugs.launchpad.net/bugs/1555640 commit b24e7ad1 upstream. X32 ABI takes the 64bit timespec, thus the timer user status ioctl becomes incompatible with IA32. This results in NOTTY error when the ioctl is issued. Meanwhile, this struct in X32 is essentially identical with the one in X86-64, so we can just bypassing to the existing code for this specific compat ioctl. Signed-off-by:

BugLink: http://bugs.launchpad.net/bugs/1555640 commit 2251fbbc upstream. Like the previous fixes for ctl and PCM, we need a fix for incompatible X32 ABI regarding the rawmidi: namely, struct snd_rawmidi_status has the timespec, and the size and the alignment on X32 differ from IA32. This patch fixes the incompatible ioctl for X32. Signed-off-by:

BugLink: http://bugs.launchpad.net/bugs/1555640 commit 02322ac9 upstream. This patch applies the microphone-related fix created for the Acer Aspire E1-572 to the E1-472 as well, as it uses the same Realtek ALC282 CODEC and demonstrates the same issues. This patch allows an external, headset microphone to be used and limits the gain on the (quite noisy) internal microphone. Signed-off-by:
