Rationale: Reduces attack surface on kernel devs opening the links for MITM as HTTPS traffic is much harder to manipulate. Deterministic algorithm: For each file: If not .svg: For each line: If doesn't contain `\bxmlns\b`: For each link, `\bhttp://[^# \t\r\n]*(?:\w|/)`: If neither `\bgnu\.org/license`, nor `\bmozilla\.org/MPL\b`: If both the HTTP and HTTPS versions return 200 OK and serve the same content: Replace HTTP with HTTPS.

csum_fold() in MIPS' asm/checksum.h is another source of sparse flooding when building different networking source code. The thing is that only half of __wsum <--> u32 casts inside the function is forced, which is insufficient. Add all necessary forced typecasting to stop floods and simplify actual bug hunting.

MIPS MMIO macros for byteswapping from/to hardware endianness are a bit tricky because they use cpu_to_le{16,32,64}() in both directions. This generates a lot of questions from sparse as __le{16,32,64} types are 'restricted' and direct cast is forbidden in order to prevent messing up the byteorder. As MMIO ops are used in almost every single driver, this leads to console flooding and complicates bug hunting. We could fix it in a more proper way, i.e. separate from device / to device byteswap macros and expand __BUILD_MEMORY_*(), but this seems redundant and will produce code duplication. Instead, just expand the existing *ioswab*() macros with forced typecasting to stop floods. Signed-off-by: -

Firstly, Loongson-2EF support ll/sc instructions, but doesn't need fix-loongson3-llsc compile option. Secondly, fix-loongson3-llsc will cause kernel startup fail at futex_init, because compiler will add 'sync' before 'll', which will affect __ex_table. futex_init will pass NULL uaddr parameter to futex_atomic_cmpxchg_inatomic. futex_atomic_cmpxchg_inatomic will access uaddr directly, which will cause page fault exception, the exception should be handled by __ex_table's nextinsn if the exception insn exsit in __ex_table. Because __ex_table is affected by compiler, the exception can not be handled, and futex_atomic_cmpxchg_inatomic will crash. Error code as below: __ex_table.insn = 1b, which is 'sync' compiled with fix-loongson3-llsc, but the actual exception instrction is ll. So, do_page_fault will not find the correct inst in __ex_table, and can not handle this exception.

The SafeSetID LSM uses the security_task_fix_setuid hook to filter set*uid() syscalls according to its configured security policy. In preparation for adding analagous support in the LSM for set*gid() syscalls, we add the requisite hook here.

This reverts commit a43a67a2. This patch reverts the main part of switching direct io implementation to iomap infrastructure. There's a problem in invalidate page that couldn't be solved as regression in this development cycle. The problem occurs when buffered and direct io are mixed, and the ranges overlap. Although this is not recommended, filesystems implement measures or fallbacks to make it somehow work. In this case, fallback to buffered IO would be an option for btrfs (this already happens when direct io is done on compressed data), but the change would be needed in the iomap code, bringing new semantics to other filesystems. Another problem arises when again the buffered and direct ios are mixed, invalidation fails, then -EIO is set on the mapping and fsync will fail, though there's no real error. There have been discussions how to fix that, but revert seems to be the least intrusive option. Link: https://lore.kernel.org/linux-btrfs/20200528192103.xm45qoxqmkw7i5yl@fiona/Signed-off-by:

On AM65xx MCU CPSW2G NUSS and 66AK2E/L NUSS allmulti setting does not allow unregistered mcast packets to pass. This happens, because ALE VLAN entries on these SoCs do not contain port masks for reg/unreg mcast packets, but instead store indexes of ALE_VLAN_MASK_MUXx_REG registers which intended for store port masks for reg/unreg mcast packets. This path was missed by commit 9d1f6447 ("net: ethernet: ti: ale: fix seeing unreg mcast packets with promisc and allmulti disabled"). Hence, fix it by taking into account ALE type in cpsw_ale_set_allmulti(). Fixes: 9d1f6447 ("net: ethernet: ti: ale: fix seeing unreg mcast packets with promisc and allmulti disabled") Signed-off-by:
