2019-01-11netfilter: nft_flow_offload: fix interaction with vrf slave devicewenxu
In the forward chain, the iif is changed from slave device to master vrf device. Thus, flow offload does not find a match on the lower slave device. This patch uses the cached route, ie. dst->dev, to update the iif and oif fields in the flow entry. After this patch, the following example works fine: # ip addr add dev eth0 1.1.1.1/24 # ip addr add dev eth1 10.0.0.1/24 # ip link add user1 type vrf table 1 # ip l set user1 up # ip l set dev eth0 master user1 # ip l set dev eth1 master user1 # nft add table firewall # nft add flowtable f fb1 { hook ingress priority 0 \; devices = { eth0, eth1 } \; } # nft add chain f ftb-all {type filter hook forward priority 0 \; policy accept \; } # nft add rule f ftb-all ct zone 1 ip protocol tcp flow offload @fb1 # nft add rule f ftb-all ct zone 1 ip protocol udp flow offload @fb1 Signed-off-by: wenxu <wenxu@ucloud.cn> Signed-off-by: Pablo Neira Ayuso <pablo@netfilter.org>
2019-01-11netfilter: ebtables: account ebt_table_info to kmemcgShakeel Butt
The [ip,ip6,arp]_tables use x_tables_info internally and the underlying memory is already accounted to kmemcg. Do the same for ebtables. The syzbot, by using setsockopt(EBT_SO_SET_ENTRIES), was able to OOM the whole system from a restricted memcg, a potential DoS. By accounting the ebt_table_info, the memory used for ebt_table_info can be contained within the memcg of the allocating process. However the lifetime of ebt_table_info is independent of the allocating process and is tied to the network namespace. So, the oom-killer will not be able to relieve the memory pressure due to ebt_table_info memory. The memory for ebt_table_info is allocated through vmalloc. Currently vmalloc does not handle the oom-killed allocating process correctly and one large allocation can bypass memcg limit enforcement. So, with this patch, at least the small allocations will be contained. For large allocations, we need to fix vmalloc.

2019-01-11i2c: dev: prevent adapter retries and timeout being set as minus valueYi Zeng
If adapter->retries is set to a minus value from user space via ioctl, it will make __i2c_transfer and __i2c_smbus_xfer skip the calling to adapter->algo->master_xfer and adapter->algo->smbus_xfer that is registered by the underlying bus drivers, and return value 0 to all the callers. The bus driver will never be accessed anymore by all users, besides, the users may still get successful return value without any error or information log print out. If adapter->timeout is set to minus value from user space via ioctl, it will make the retrying loop in __i2c_transfer and __i2c_smbus_xfer always break after the the first try, due to the time_after always returns true.

2019-01-10tcp: change txhash on SYN-data timeoutYuchung Cheng
Previously upon SYN timeouts the sender recomputes the txhash to try a different path. However this does not apply on the initial timeout of SYN-data (active Fast Open). Therefore an active IPv6 Fast Open connection may incur one second RTO penalty to take on a new path after the second SYN retransmission uses a new flow label. This patch removes this undesirable behavior so Fast Open changes the flow label just like the regular connections. This also helps avoid falsely disabling Fast Open on the sender which triggers after two consecutive SYN timeouts on Fast Open.

git://git.kernel.org/pub/scm/linux/kernel/git/palmer/riscv-linux Pull RISC-V updates from Palmer Dabbelt: "This tag contains a handful of updates that slipped through the cracks during the merge window due to the holidays. The fixes are mostly independent, with the exception of one larger audit-related branch. Core RISC-V updates: - The BSS has been moved, which shrinks flat images. - A fix to test-bpf so it compiles on RV64I-based systems. - A fix to respect the kernel commandline when there is no device tree. - A fix to prevent CPUs from trying to put themselves to sleep when bringing down the system. - Support for MODULE_SECTIONS on RV32I-based systems. - [new in v2] The addition of an SBI earlycon driver. This is definately a new feature, but I'd like to include it now because I dropped this patch when submitting the merge window PR that removed our EARLY_PRINTK support. RISC-V audit updates: - The addition of NR_syscalls into unistd.h, which is necessary for CONFIG_FTRACE_SYSCALLS. - The definition of CREATE_TRACE_POINTS so __tracepoint_sys_{enter,exit} get defined. - A fix for trace_sys_exit() so we can enable HAVE_SYSCALL_TRACEPOINTS As usual, I've tested this by booting a Fedora-based image on a recent QEMU (this time just whatever I had lying around). * tag 'riscv-for-linus-4.21-rc2-v2' of git://git.kernel.org/pub/scm/linux/kernel/git/palmer/riscv-linux: tty/serial: Add RISC-V SBI earlycon support riscv: add HAVE_SYSCALL_TRACEPOINTS to Kconfig riscv: fix trace_sys_exit hook riscv: define CREATE_TRACE_POINTS in ptrace.c riscv: define NR_syscalls in unistd.h riscv: audit: add audit hook in do_syscall_trace_enter/exit() riscv: add audit support RISC-V: Support MODULE_SECTIONS mechanism on RV32 MAINTAINERS: SiFive drivers: add myself as a SiFive driver maintainer MAINTAINERS: SiFive drivers: change the git tree to a SiFive git tree riscv: don't stop itself in smp_send_stop arch: riscv: support kernel command line forcing when no DTB passed tools uapi: fix RISC-V 64-bit support RISC-V: Make BSS section as the last section in vmlinux.lds.S

2019-01-10CIFS: Fix credit computation for compounded requestsPavel Shilovsky
In SMB3 protocol every part of the compound chain consumes credits individually, so we need to call wait_for_free_credits() for each of the PDUs in the chain. If an operation is interrupted, we must ensure we return all credits taken from the server structure back. Without this patch server can sometimes disconnect the session due to credit mismatches, especially when first operation(s) are large writes.

2019-01-10CIFS: Do not set credits to 1 if the server didn't grant anythingPavel Shilovsky
Currently we reset the number of total credits granted by the server to 1 if the server didn't grant us anything int the response. This violates the SMB3 protocol - we need to trust the server and use the credit values from the response. Fix this by removing the corresponding code.

2019-01-10CIFS: Fix adjustment of credits for MTU requestsPavel Shilovsky
Currently for MTU requests we allocate maximum possible credits in advance and then adjust them according to the request size. While we were adjusting the number of credits belonging to the server, we were skipping adjustment of credits belonging to the request. This patch fixes it by setting request credits to CreditCharge field value of SMB2 packet header. Also ask 1 credit more for async read and write operations to increase parallelism and match the behavior of other operations.

2019-01-10dm crypt: fix parsing of extended IV argumentsMilan Broz
The dm-crypt cipher specification in a mapping table is defined as: cipher[:keycount]-chainmode-ivmode[:ivopts] or (new crypt API format): capi:cipher_api_spec-ivmode[:ivopts] For ESSIV, the parameter includes hash specification, for example: aes-cbc-essiv:sha256 The implementation expected that additional IV option to never include another dash '-' character. But, with SHA3, there are names like sha3-256; so the mapping table parser fails: dmsetup create test --table "0 8 crypt aes-cbc-essiv:sha3-256 9c1185a5c5e9fc54612808977ee8f5b9e 0 /dev/sdb 0" or (new crypt API format) dmsetup create test --table "0 8 crypt capi:cbc(aes)-essiv:sha3-256 9c1185a5c5e9fc54612808977ee8f5b9e 0 /dev/sdb 0" device-mapper: crypt: Ignoring unexpected additional cipher options device-mapper: table: 253:0: crypt: Error creating IV device-mapper: ioctl: error adding target to table Fix the dm-crypt constructor to ignore additional dash in IV options and also remove a bogus warning (that is ignored anyway).

2019-01-10ARM: dts: exynos: Fix eMMC regulator properties on Odroid U3 boardsMarek Szyprowski
LDO20 regulator provides power for the MMC card on Odroid U3 boards. That regulator has been marked as 'boot-on' since the beginning of Odroid X/U3 support, but such flag is not really needed for it. That regulator is correctly described as supply for eMMC card and controlled by its driver. Commit 05f224ca6693 ("regulator: core: Clean enabling always-on regulators + their supplies") changed the way the boot-on regulators are handled and since then regulators marked as 'boot-on' got increased reference count and are not turned off for the system suspend time. The new approach turned out to break suspend/resume support on Odroid U3 with eMMC card, because the card is not properly shutdown due to missing of power cycle. Fix this by removing excessive 'boot-on' flag and let MMC driver to control turning power on and off.
