[ Upstream commit 879e5a0df626f39cbb3c61bb90373e56d67012c4 ]
Fix:
WARNING: drivers/video/fbdev/pmag-ba-fb.o(.text+0x308): Section mismatch in reference from the function pmagbafb_probe() to the function .init.text:pmagbafb_erase_cursor() The function pmagbafb_probe() references the function __init pmagbafb_erase_cursor(). This is often because pmagbafb_probe lacks a __init annotation or the annotation of pmagbafb_erase_cursor is wrong.
-- a fallout from a missed update from commit 9625b51350cc ("VIDEO: PMAG-BA: Fix section mismatch") and then commit 48c68c4f1b54 ("Drivers: video: remove __dev* attributes.")

From: Jason Gunthorpe jgunthorpe@obsidianresearch.com
[ Upstream commit d9bf28e2650fe3eeefed7e34841aea07d10c6543 ]
The PCI core will write to the bridge window config multiple times while they are enabled. This can lead to mbus failures like this:
mvebu_mbus: cannot add window '4:e8', conflicts with another window mvebu-pcie mbus:pex@e0000000: Could not create MBus window at [mem 0xe0000000-0xe00fffff]: -22
For me this is happening during a hotplug cycle. The PCI core is not changing the values, just writing them twice while active.
The patch addresses the general case of any change to an active window, but not atomically. The code is slightly refactored so io and mem can share more of the window logic.

The default for the maximum number of tx/rx queues of one interface is the number of cpus of the system today. As each queue pair reserves 512 grant pages this default consumes a ridiculous number of grants for large guests.
Limit the queue number to 8 as default. This value can be modified via a module parameter if required.

The pinmux configuration in device tree was different from manual muxing in <u-boot>/board/freescale/mx53loco/mx53loco.c All pins were configured as NO_PAD_CTL(1 << 31), which was fine as the bootloader already did the correct pinmuxing for us. But recently u-boot is migrating to reuse device tree files from the kernel tree, so it seems to be better to have the correct pinmuxing in our files, too.

Some counters are added in Commit 6e0365b78273 ("KVM: PPC: Book3S HV: Add ICP real mode counters"), to provide some performance statistics to determine whether further optimizing is needed for real mode functions.
The n_reject counter counts how many times ICP rejects an irq because of priority in real mode. The redelivery of an lsi that is still asserted after eoi doesn't fall into this category, so the increasement there is removed.
Also, it needs to be increased in icp_rm_deliver_irq() if it rejects another one.

The arm64 DMA-mapping implementation sets the DMA ops to the IOMMU DMA ops if we detect that an IOMMU is present for the master and the DMA ranges are valid.
In the case when the IOMMU domain for the device is not of type IOMMU_DOMAIN_DMA, then we have no business swizzling the ops, since we're not in control of the underlying address space. This patch leaves the DMA ops alone for masters attached to non-DMA IOMMU domains.

[ Upstream commit 10e840dfb0b7fc345082dd9e5fff3c1c02e7690e ]
These stand-alone trigger drivers were using iio_trigger_put() where they should have been using iio_trigger_free(). The iio_trigger_put() adds a module_put which is bad since they never did a module_get.
In the sysfs driver, module_get/put's are used as triggers are added & removed. This extra module_put() occurs on an error path in the probe routine (probably rare).
In the bfin-timer & interrupt trigger drivers, the module resources are not explicitly managed, so it's doing a put on something that was never get'd. It occurs on the probe error path and on the remove path (not so rare).
Tested with the sysfs trigger driver. The bfin & interrupt drivers were build tested & inspected only.

Driver was checking for direct mode before changing oversampling ratios, but was not locking it. Use the claim/release helper functions to guarantee the device stays in direct mode while the oversampling ratios are being updated. Continue to use the drivers private state lock to protect against conflicting direct mode access of the state data.

Function lbs_cmd_802_11_sleep_params() always return 0, even if the call to lbs_cmd_with_response() fails. In this case, the parameter @sp will keep uninitialized. Because the return value is 0, its caller (say lbs_sleepparams_read()) will not detect the error, and will copy the uninitialized stack memory to user sapce, resulting in stack information leak. To avoid the bug, this patch returns variable ret (which takes the return value of lbs_cmd_with_response()) instead of 0.

ah4 input processing uses the asynchronous hash crypto API which supplies an error code as part of the operation completion but the error code was being ignored.
Treat a crypto API error indication as a verification failure.
While a crypto API reported error would almost certainly result in a memcpy of the digest failing anyway and thus the security risk seems minor, performing a memory compare on what might be uninitialized memory is wrong.

The "topology=off" kernel parameter is supposed to prevent the kernel to use hardware topology information to generate scheduling domains etc. For an unknown reason I implemented this in a very odd way back then: instead of simply clearing the MACHINE_HAS_TOPOLOGY flag within the lowcore I added a second variable which indicated that topology information should not be used. This is more than suboptimal since it partially doesn't work. For the fake NUMA case topology information is still considered and scheduling domains will be created based on this. To fix this and to simplify the code get rid of the extra variable and implement the "topology=off" case like it is done for other features.

On context switch with powerpc32, the cputime is accumulated in the thread_info struct. So the switching-in task must move forward its start time snapshot to the current time in order to later compute the delta spent in system mode.
This is what we do for the normal cputime by initializing the starttime field to the value of the previous task's starttime which got freshly updated.
But we are missing the update of the scaled cputime start time. As a result we may be accounting too much scaled cputime later.
Fix this by initializing the scaled cputime the same way we do for normal cputime.

qeth devices in layer3 mode need a separate handling of vipa and proxy-arp addresses. vipa and proxy-arp addresses processed by qeth can be read from userspace. Introduced with commit 5f78e29ceebf ("qeth: optimize IP handling in rx_mode callback") the retrieval of vipa and proxy-arp addresses is broken, if more than one vipa or proxy-arp address are set.
The qeth code used local variable "int i" for 2 different purposes. This patch now spends 2 separate local variables of type "int". While touching these functions hash_for_each_safe() is converted to hash_for_each(), since there is no removal of hash entries.

As the previous patch did for encrypted-keys, zero sensitive any potentially sensitive data related to the "trusted" key type before it is freed. Notably, we were not zeroing the tpm_buf structures in which the actual key is stored for TPM seal and unseal, nor were we zeroing the trusted_key_payload in certain error paths.

commit a3c812f7cfd80cf51e8f5b7034f7418f6beb56c1 upstream.
When calling keyctl_read() on a key of type "trusted", if the user-supplied buffer was too small, the kernel ignored the buffer length and just wrote past the end of the buffer, potentially corrupting userspace memory. Fix it by instead returning the size required, as per the documentation for keyctl_read().
We also don't even fill the buffer at all in this case, as this is slightly easier to implement than doing a short read, and either behavior appears to be permitted. It also makes it match the behavior of the "encrypted" key type.

commit 441f99c90497e15aa3ad1dbabd56187e29614348 upstream.
The IV buffer used during CCM operations is used twice, during both the hashing step and the ciphering step.
When using a hardware accelerator that updates the contents of the IV buffer at the end of ciphering operations, the value will be modified. In the decryption case, the subsequent setup of the hashing algorithm will interpret the updated IV instead of the original value, which can lead to out-of-bounds writes.
Reuse the idata buffer, only used in the hashing step, to preserve the IV's value during the ciphering step in the decryption case.

commit d041b557792c85677f17e08eee535eafbd6b9aa2 upstream.
struct sha1_ctx_mgr allocated in sha1_mb_mod_init() via kzalloc() and later passed in sha1_mb_flusher_mgr_flush_avx2() function where instructions vmovdqa used to access the struct. vmovdqa requires 16-bytes aligned argument, but nothing guarantees that struct sha1_ctx_mgr will have that alignment. Unaligned vmovdqa will generate GP fault.
Fix this by replacing vmovdqa with vmovdqu which doesn't have alignment requirements.

commit 624f5ab8720b3371367327a822c267699c1823b8 upstream.
syzkaller reported a NULL pointer dereference in asn1_ber_decoder(). It can be reproduced by the following command, assuming CONFIG_PKCS7_TEST_KEY=y:
keyctl add pkcs7_test desc '' @s
The bug is that if the data buffer is empty, an integer underflow occurs in the following check:
if (unlikely(dp >= datalen - 1)) goto data_overrun_error;
This results in the NULL data pointer being dereferenced.
Fix it by checking for 'datalen - dp < 2' instead.
Also fix the similar check for 'dp >= datalen - n' later in the same function. That one possibly could result in a buffer overread.
The NULL pointer dereference was reproducible using the "pkcs7_test" key type but not the "asymmetric" key type because the "asymmetric" key type checks for a 0-length payload before calling into the ASN.1 decoder but the "pkcs7_test" key type does not.
The bug report was:

commit b9dd05c7002ee0ca8b676428b2268c26399b5e31 upstream.
When CONFIG_DEBUG_USER is enabled, it's possible for a user to deliberately trigger dump_instr() with a chosen kernel address.
Let's avoid problems resulting from this by using get_user() rather than __get_user(), ensuring that we don't erroneously access kernel memory.
So that we can use the same code to dump user instructions and kernel instructions, the common dumping code is factored out to __dump_instr(), with the fs manipulated appropriately in dump_instr() around calls to this.

commit 132d358b183ac6ad8b3fea32ad5e0663456d18d1 upstream.
The SYSEX event delivery in OSS sequencer emulation assumed that the event is encoded in the variable-length data with the straight buffering. This was the normal behavior in the past, but during the development, the chained buffers were introduced for carrying more data, while the OSS code was left intact. As a result, when a SYSEX event with the chained buffer data is passed to OSS sequencer port, it may end up with the wrong memory access, as if it were having a too large buffer.
This patch addresses the bug, by applying the buffer data expansion by the generic snd_seq_dump_var_event() helper function.

commit 3510c7aa069aa83a2de6dab2b41401a198317bdc upstream.
The recent fix for adding rwsem nesting annotation was using the given "hop" argument as the lock subclass key. Although the idea itself works, it may trigger a kernel warning like: BUG: looking up invalid subclass: 8 .... since the lockdep has a smaller number of subclasses (8) than we currently allow for the hops there (10).
The current definition is merely a sanity check for avoiding the too deep delivery paths, and the 8 hops are already enough. So, as a quick fix, just follow the max hops as same as the max lockdep subclasses.

commit 6a6cba1d945a7511cdfaf338526871195e420762 upstream.
The default CM target field in the GCR_BASE register is encoded with 0 meaning memory & 1 being reserved. However the definitions we use for those bits effectively get these two values backwards - likely because they were copied from the definitions for the CM regions where the target is encoded differently. This results in use setting up GCR_BASE with the reserved target value by default, rather than targeting memory as intended. Although we currently seem to get away with this it's not a great idea to rely upon.
Fix this by changing our macros to match the documentated target values.
The incorrect encoding became used as of commit 9f98f3dd0c51 ("MIPS: Add generic CM probe & access code") in the Linux v3.15 cycle, and was likely carried forwards from older but unused code introduced by commit 39b8d5254246 ("[MIPS] Add support for MIPS CMP platform.") in the v2.6.26 cycle.

commit a00eeede507c975087b7b8df8cf2c9f88ba285de upstream.
If a secondary CPU failed to start, for any reason, the CPU requesting the secondary to start would get stuck in the loop waiting for the secondary to be present in the cpu_callin_map.
Rather than that, use a completion event to signal that the secondary CPU has started and is waiting to synchronise counters.
Since the CPU presence will no longer be marked in cpu_callin_map, remove the redundant test from arch_cpu_idle_dead().

commit 6f542ebeaee0ee552a902ce3892220fc22c7ec8e upstream.
While testing cpu hoptlug (cpu down and up in loops) on kernel 4.4, it was observed that occasionally check for cpu online will fail in kernel/cpu.c, _cpu_up:
https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux-stable.git/tree... 518 /* Arch-specific enabling code. */ 519 ret = __cpu_up(cpu, idle); 520 521 if (ret != 0) 522 goto out_notify; 523 BUG_ON(!cpu_online(cpu));
Reason is race between start_secondary and _cpu_up. cpu_callin_map is set before cpu_online_mask. In __cpu_up, cpu_callin_map is waited for, but cpu online mask is not, resulting in race in which secondary processor started and set cpu_callin_map, but not yet set the online mask,resulting in above BUG being hit.
Upstream differs in the area. cpu_online check is in bringup_wait_for_ap, which is after cpu reached AP_ONLINE_IDLE,where secondary passed its start function. Nonetheless, fix makes start_secondary safe and not depending on other locks throughout the code. It protects as well against cpu_online checks put in between sometimes in the future.
Fix this by moving completion after all flags are set.

commit 9e8c399a88f0b87e41a894911475ed2a8f8dff9e upstream.
Commit 6f542ebeaee0 ("MIPS: Fix race on setting and getting cpu_online_mask") effectively reverted commit 8f46cca1e6c06 ("MIPS: SMP: Fix possibility of deadlock when bringing CPUs online") and thus has reinstated the possibility of deadlock.
The commit was based on testing of kernel v4.4, where the CPU hotplug core code issued a BUG() if the starting CPU is not marked online when the boot CPU returns from __cpu_up. The commit fixes this race (in v4.4), but re-introduces the deadlock situation.
As noted in the commit message, upstream differs in this area. Commit 8df3e07e7f21f ("cpu/hotplug: Let upcoming cpu bring itself fully up") adds a completion event in the CPU hotplug core code, making this race impossible. However, people were unhappy with relying on the core code to do the right thing.
To address the issues both commits were trying to fix, add a second completion event in the MIPS smp hotplug path. It removes the possibility of a race, since the MIPS smp hotplug code now synchronises both the boot and secondary CPUs before they return to the hotplug core code. It also addresses the deadlock by ensuring that the secondary CPU is not marked online before it's counters are synchronised.
This fix should also be backported to fix the race condition introduced by the backport of commit 8f46cca1e6c06 ("MIPS: SMP: Fix possibility of deadlock when bringing CPUs online"), through really that race only existed before commit 8df3e07e7f21f ("cpu/hotplug: Let upcoming cpu bring itself fully up").

With Wayland desktop and atomic mode set, during the mode setting process there is a moment when two framebuffer sized surfaces are being pinned. This was not an issue with Xorg.
Since this only happens during a mode change, there should be no performance impact by increasing allowable mem_size.

commit 651e4769ba2a9f20c4b8a823ae2727bf7fa9c9f0 upstream.
In chasing down issues with EDID probing, I found some duplicated but incomplete logic used to power the chip on and off.
This patch refactors the adv7511_power_on/off functions, so they can be used for internal needs.

commit 4226d9b127cf4758ba0e07931b3f0d59f1b1a50c upstream.
Thus this patch changes the EDID probing logic so that we re-use the __adv7511_power_on/off() calls instead of duplciating logic.
This does change behavior slightly as it adds the HPD signal pulse to the EDID probe path, but Archit has had a patch to add HPD signal pulse to the EDID probe path before, so this should address the cases where that helped. Another difference is that regcache_mark_dirty() is also called in the power off path once EDID is probed.

commit 3587c856675c45809010c2cee5b21096f6e8e938 upstream.
I've found that by just turning the chip on and off via the POWER_DOWN register, I end up getting i2c_transfer errors on HiKey.
Investigating further, it turns out that some of the register state in hardware is getting lost, as the device registers are reset when the chip is powered down.
Thus this patch simply re-writes the i2c address to the ADV7511_REG_EDID_I2C_ADDR register to ensure its properly set before we try to read the EDID data.

commit e1bf1687740ce1a3598a1c5e452b852ff2190682 upstream.
This reverts commit 870190a9ec9075205c0fa795a09fa931694a3ff1.
It was not a good idea. The custom hash table was a much better fit for this purpose.
A fast lookup is not essential, in fact for most cases there is no lookup at all because original tuple is not taken and can be used as-is. What needs to be fast is insertion and deletion.
rhlist removal however requires a rhlist walk. We can have thousands of entries in such a list if source port/addresses are reused for multiple flows, if this happens removal requests are so expensive that deletions of a few thousand flows can take several seconds(!).
The advantages that we got from rhashtable are: 1) table auto-sizing 2) multiple locks
1) would be nice to have, but it is not essential as we have at most one lookup per new flow, so even a million flows in the bysource table are not a problem compared to current deletion cost. 2) is easy to add to custom hash table.
I tried to add hlist_node to rhlist to speed up rhltable_remove but this isn't doable without changing semantics. rhltable_remove_fast will check that the to-be-deleted object is part of the table and that requires a list walk that we want to avoid.
Furthermore, using hlist_node increases size of struct rhlist_head, which in turn increases nf_conn size.

Hi Greg,
Please, hold on a bit with this revert patch entitled:
nat: Revert "netfilter: nat: convert nat bysrc hash to rhashtable")
for 4.9-stable.
Until we clarify what is going on.
Guillame (he's on Cc) is reporting some problems after this.
Thanks!

Hi Greg,
Please, hold on a bit with this revert patch entitled:

Until we clarify what is going on.
Guillame (he's on Cc) is reporting some problems after this.
Thanks!

From: Florian Westphal fw@strlen.de
commit e1bf1687740ce1a3598a1c5e452b852ff2190682 upstream.
This reverts commit 870190a9ec9075205c0fa795a09fa931694a3ff1.
It was not a good idea. The custom hash table was a much better fit for this purpose.
A fast lookup is not essential, in fact for most cases there is no lookup at all because original tuple is not taken and can be used as-is. What needs to be fast is insertion and deletion.
rhlist removal however requires a rhlist walk. We can have thousands of entries in such a list if source port/addresses are reused for multiple flows, if this happens removal requests are so expensive that deletions of a few thousand flows can take several seconds(!).
The advantages that we got from rhashtable are:
table auto-sizing
multiple locks
would be nice to have, but it is not essential as we have at
most one lookup per new flow, so even a million flows in the bysource table are not a problem compared to current deletion cost. 2) is easy to add to custom hash table.
I tried to add hlist_node to rhlist to speed up rhltable_remove but this isn't doable without changing semantics. rhltable_remove_fast will check that the to-be-deleted object is part of the table and that requires a list walk that we want to avoid.
Furthermore, using hlist_node increases size of struct rhlist_head, which in turn increases nf_conn size.

From: Pavel Tatashin pasha.tatashin@oracle.com
commit 76ce7cfe35ef58f34e6ba85327afb5fbf6c3ff9b upstream.
If the TSC has constant frequency then the delay calibration can be skipped when it has been calibrated for a package already. This is checked in calibrate_delay_is_known(), but that function is buggy in two aspects:
It returns 'false' if
(!tsc_disabled && !cpu_has(&cpu_data(cpu), X86_FEATURE_CONSTANT_TSC)
which is obviously the reverse of the intended check and the check for the sibling mask cannot work either because the topology links have not been set up yet.
Correct the condition and move the call to set_cpu_sibling_map() before invoking calibrate_delay() so the sibling check works correctly.

These accessors should not have been used in the first place: it is PPro so no mixed silicon revisions and thus it can simply use boot_cpu_data.

Can you run 'git bisect' or if you use quilt, do a manual bisect to find the offending patch?

Can you run 'git bisect' or if you use quilt, do a manual bisect to find the offending patch?
already done
netfilter: nat: Revert "netfilter: nat: convert nat bysrc hash to rhashtable"
this one caused the crash. if i revert it, its working again

Ah nice. Do you also have the crash in 4.14 with that patch, as it is in there too.

Results from Linaro’s test farm. I’ll make one note. As we had an infra issue during the 4.9.61 release (not the RC cycle) for the purposes of regression detection we’re using the 4.9.60 release as it’s data is more complete and provides a good comparison point.
