Mask the ECN bits before calling ip_route_output_ports(). The tos variable might be passed directly from an IPv4 header, so it may have the last ECN bit set. This interferes with the route lookup process as ip_route_output_key_hash() interpretes this bit specially (to restrict the route scope). Found by code inspection, compile tested only.

Similar to commit 94e22389 ("xfrm4: strip ECN bits from tos field"), clear the ECN bits from iph->tos when setting ->flowi4_tos. This ensures that the last bit of ->flowi4_tos is cleared, so ip_route_output_key_hash() isn't going to restrict the scope of the route lookup. Use ~INET_ECN_MASK instead of IPTOS_RT_MASK, because we have no reason to clear the high order bits. Found by code inspection, compile tested only.

Commit 2c865a8a ("netfilter: nf_tables: add rule blob layout") never initialized the new 'data_size' variable. I'm not sure how it ever worked, but it might have worked almost by accident - gcc seems to occasionally miss these kinds of 'variable used uninitialized' situations, but I've seen it do so because it ended up zero-initializing them due to some other simplification. But clang is very unhappy about it all, and correctly reports net/netfilter/nf_tables_api.c:8278:4: error: variable 'data_size' is uninitialized when used here [-Werror,-Wuninitialized] data_size += sizeof(*prule) + rule->dlen; ^~~~~~~~~ net/netfilter/nf_tables_api.c:8263:30: note: initialize the variable 'data_size' to silence this warning unsigned int size, data_size; ^ = 0 1 error generated. and this fix just initializes 'data_size' to zero before the loop.

Pull random number generator updates from Jason Donenfeld: "These a bit more numerous than usual for the RNG, due to folks resubmitting patches that had been pending prior and generally renewed interest. There are a few categories of patches in here: 1) Dominik Brodowski and I traded a series back and forth for a some weeks that fixed numerous issues related to seeds being provided at extremely early boot by the firmware, before other parts of the kernel or of the RNG have been initialized, both fixing some crashes and addressing correctness around early boot randomness. One of these is marked for stable. 2) I replaced the RNG's usage of SHA-1 with BLAKE2s in the entropy extractor, and made the construction a bit safer and more standard. This was sort of a long overdue low hanging fruit, as we were supposed to have phased out SHA-1 usage quite some time ago (even if all we needed here was non-invertibility). Along the way it also made extraction 131% faster. This required a bit of Kconfig and symbol plumbing to make things work well with the crypto libraries, which is one of the reasons why I'm sending you this pull early in the cycle. 3) I got rid of a truly superfluous call to RDRAND in the hot path, which resulted in a whopping 370% increase in performance. 4) Sebastian Andrzej Siewior sent some patches regarding PREEMPT_RT, the full series of which wasn't ready yet, but the first two preparatory cleanups were good on their own. One of them touches files in kernel/irq/, which is the other reason why I'm sending you this pull early in the cycle. 5) Other assorted correctness fixes from Eric Biggers, Jann Horn, Mark Brown, Dominik Brodowski, and myself" * 'random-5.17-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/crng/random: random: don't reset crng_init_cnt on urandom_read() random: avoid superfluous call to RDRAND in CRNG extraction random: early initialization of ChaCha constants random: use IS_ENABLED(CONFIG_NUMA) instead of ifdefs random: harmonize "crng init done" messages random: mix bootloader randomness into pool random: do not throw away excess input to crng_fast_load random: do not re-init if crng_reseed completes before primary init random: fix crash on multiple early calls to add_bootloader_randomness() random: do not sign extend bytes for rotation when mixing random: use BLAKE2s instead of SHA1 in extraction lib/crypto: blake2s: include as built-in random: fix data race on crng init time random: fix data race on crng_node_pool irq: remove unused flags argument from __handle_irq_event_percpu() random: remove unused irq_flags argument from add_interrupt_randomness() random: document add_hwgenerator_randomness() with other input functions MAINTAINERS: add git tree for random.c
