2018-07-30ARM: 8781/1: Fix Thumb-2 syscall return for binutils 2.29+Vincent Whitchurch
When building the kernel as Thumb-2 with binutils 2.29 or newer, if the assembler has seen the .type directive (via ENDPROC()) for a symbol, it automatically handles the setting of the lowest bit when the symbol is used with ADR. The badr macro on the other hand handles this lowest bit manually. This leads to a jump to a wrong address in the wrong state in the syscall return path: Internal error: Oops - undefined instruction: 0 [#2] SMP THUMB2 Modules linked in: CPU: 0 PID: 652 Comm: modprobe Tainted: G D 4.18.0-rc3+ #8 PC is at ret_fast_syscall+0x4/0x62 LR is at sys_brk+0x109/0x128 pc : [<80101004>] lr : [<801c8a35>] psr: 60000013 Flags: nZCv IRQs on FIQs on Mode SVC_32 ISA ARM Segment none Control: 50c5387d Table: 9e82006a DAC: 00000051 Process modprobe (pid: 652, stack limit = 0x(ptrval)) 80101000 <ret_fast_syscall>: 80101000: b672 cpsid i 80101002: f8d9 2008 ldr.w r2, [r9, #8] 80101006: f1b2 4ffe cmp.w r2, #2130706432 ; 0x7f000000 80101184 <local_restart>: 80101184: f8d9 a000 ldr.w sl, [r9] 80101188: e92d 0030 stmdb sp!, {r4, r5} 8010118c: f01a 0ff0 tst.w sl, #240 ; 0xf0 80101190: d117 bne.n 801011c2 <__sys_trace> 80101192: 46ba mov sl, r7 80101194: f5ba 7fc8 cmp.w sl, #400 ; 0x190 80101198: bf28 it cs 8010119a: f04f 0a00 movcs.w sl, #0 8010119e: f3af 8014 nop.w {20} 801011a2: f2af 1ea2 subw lr, pc, #418 ; 0x1a2 To fix this, add a new symbol name which doesn't have ENDPROC used on it and use that with badr.

This patch implements the feature described in rfc1812#section-5.3.5.2 and rfc2644. It allows the router to forward directed broadcast when sysctl bc_forwarding is enabled. Note that this feature could be done by iptables -j TEE, but it would cause some problems: - target TEE's gateway param has to be set with a specific address, and it's not flexible especially when the route wants forward all directed broadcasts. - this duplicates the directed broadcasts so this may cause side effects to applications. Besides, to keep consistent with other os router like BSD, it's also necessary to implement it in the route rx path. Note that route cache needs to be flushed when bc_forwarding is changed.

2018-07-29ext4: fix check to prevent initializing reserved inodesTheodore Ts'o
Commit 8844618d8aa7: "ext4: only look at the bg_flags field if it is valid" will complain if block group zero does not have the EXT4_BG_INODE_ZEROED flag set. Unfortunately, this is not correct, since a freshly created file system has this flag cleared. It gets almost immediately after the file system is mounted read-write --- but the following somewhat unlikely sequence will end up triggering a false positive report of a corrupted file system: mkfs.ext4 /dev/vdc mount -o ro /dev/vdc /vdc mount -o remount,rw /dev/vdc Instead, when initializing the inode table for block group zero, test to make sure that itable_unused count is not too large, since that is the case that will result in some or all of the reserved inodes getting cleared. This fixes the failures reported by Eric Whiteney when running generic/230 and generic/231 in the the nojournal test case.

2018-07-29NET: stmmac: align DMA stuff to largest cache line lengthEugeniy Paltsev
As for today STMMAC_ALIGN macro (which is used to align DMA stuff) relies on L1 line length (L1_CACHE_BYTES). This isn't correct in case of system with several cache levels which might have L1 cache line length smaller than L2 line. This can lead to sharing one cache line between DMA buffer and other data, so we can lose this data while invalidate DMA buffer before DMA transaction. Fix that by using SMP_CACHE_BYTES instead of L1_CACHE_BYTES for aligning. Signed-off-by: Eugeniy Paltsev <Eugeniy.Paltsev@synopsys.com> Signed-off-by: David S. Miller <davem@davemloft.net>

2018-07-29ACPICA: AML Parser: ignore control method status in module-level codeErik Schmauss
Previous change in the AML parser code blindly set all non-successful dispatcher statuses to AE_OK. That approach is incorrect, though, because successful control method invocations from module-level return AE_CTRL_TRANSFER. Overwriting AE_OK to this status causes the AML parser to think that there was no return value from the control method invocation.

2018-07-28tls: Fix improper revert in zerocopy_from_iterDoron Roberts-Kedes
The current code is problematic because the iov_iter is reverted and never advanced in the non-error case. This patch skips the revert in the non-error case. This patch also fixes the amount by which the iov_iter is reverted. Currently, iov_iter is reverted by size, which can be greater than the amount by which the iter was actually advanced. Instead, only revert by the amount that the iter was advanced.

2018-07-28tcp_bbr: fix bw probing to raise in-flight data for very small BDPsNeal Cardwell
For some very small BDPs (with just a few packets) there was a quantization effect where the target number of packets in flight during the super-unity-gain (1.25x) phase of gain cycling was implicitly truncated to a number of packets no larger than the normal unity-gain (1.0x) phase of gain cycling. This meant that in multi-flow scenarios some flows could get stuck with a lower bandwidth, because they did not push enough packets inflight to discover that there was more bandwidth available. This was really only an issue in multi-flow LAN scenarios, where RTTs and BDPs are low enough for this to be an issue. This fix ensures that gain cycling can raise inflight for small BDPs by ensuring that in PROBE_BW mode target inflight values with a super-unity gain are always greater than inflight values with a gain <= 1. Importantly, this applies whether the inflight value is calculated for use as a cwnd value, or as a target inflight value for the end of the super-unity phase in bbr_is_next_cycle_phase() (both need to be bigger to ensure we can probe with more packets in flight reliably). This is a candidate fix for stable releases.
