2020-02-26netfilter: xt_hashlimit: unregister proc file before releasing mutexCong Wang
Before releasing the global mutex, we only unlink the hashtable from the hash list, its proc file is still not unregistered at this point. So syzbot could trigger a race condition where a parallel htable_create() could register the same file immediately after the mutex is released. Move htable_remove_proc_entry() back to mutex protection to fix this. And, fold htable_destroy() into htable_put() to make the code slightly easier to understand.

2020-02-26ethtool: limit bitset sizeMichal Kubecek
Syzbot reported that ethnl_compact_sanity_checks() can be tricked into reading past the end of ETHTOOL_A_BITSET_VALUE and ETHTOOL_A_BITSET_MASK attributes and even the message by passing a value between (u32)(-31) and (u32)(-1) as ETHTOOL_A_BITSET_SIZE. The problem is that DIV_ROUND_UP(attr_nbits, 32) is 0 for such values so that zero length ETHTOOL_A_BITSET_VALUE will pass the length check but ethnl_bitmap32_not_zero() check would try to access up to 512 MB of attribute "payload". Prevent this overflow byt limiting the bitset size. Technically, compact bitset format would allow bitset sizes up to almost 2^18 (so that the nest size does not exceed U16_MAX) but bitsets used by ethtool are much shorter. S16_MAX, the largest value which can be directly used as an upper limit in policy, should be a reasonable compromise.

2020-02-26drm/amdkfd: Delete unnecessary unmap queue package submissionsYong Zhao
The previous way of using SDMA queue count to infer whether we should unmap SDMA engines has bugs. The reason it did not cause issues is because MEC firmware unmaps all queues (CP + SDMA) when a unmap package for compute engine is received. Becasue of that, only one unmap queue package is needed, instead of one unmap queue package for CP and each SDMA engine, which results in much simpler driver code.

It's the last user, and more importantly, it's the last non-legacy user of anything in drm_pci.c. The only tricky bit is the agp initialization. But a close look shows that radeon does not use the drm_agp midlayer (the main use of that is drm_bufs for legacy drivers), and instead could use the agp subsystem directly (like nouveau does already). Hence we can just pull this in too. A further step would be to entirely drop the use of drm_device->agp, but feels like too much churn just for this patch.

Recent omap changes added runtime checks to use omap_smccc_smc() when optee is configured in dts. As the omap-secure code can be built for ARMv6 only without ARMv7 and use custom smc calls, we now get a build error: omap-secure.c:(.text+0x94): undefined reference to `__arm_smccc_smc' As there secure calls are not used for ARMv6, we should not build secure-common, and not call omap_secure_init() for omap2.
