ipmi: Prefer ACPI system interfaces over SMBIOS ones

2017-11-24T07:37:05+00:00

commit 7e030d6dff713250c7dcfb543cad2addaf479b0e upstream. The recent changes to add SMBIOS (DMI) IPMI interfaces as platform devices caused DMI to be selected before ACPI, causing ACPI type of operations to not work. Signed-off-by: Corey Minyard Signed-off-by: Greg Kroah-Hartman

ipmi: fix unsigned long underflow

2017-11-24T07:37:04+00:00

commit 392a17b10ec4320d3c0e96e2a23ebaad1123b989 upstream. When I set the timeout to a specific value such as 500ms, the timeout event will not happen in time due to the overflow in function check_msg_timeout: ... ent->timeout -= timeout_period; if (ent->timeout > 0) return; ... The type of timeout_period is long, but ent->timeout is unsigned long. This patch makes the type consistent.

tpm-dev-common: Reject too short writes

2017-11-24T07:37:04+00:00

commit ee70bc1e7b63ac8023c9ff9475d8741e397316e7 upstream. tpm_transmit() does not offer an explicit interface to indicate the number of valid bytes in the communication buffer. Instead, it relies on the commandSize field in the TPM header that is encoded within the buffer. Therefore, ensure that a) enough data has been written to the buffer, so that the commandSize field is present and b) the commandSize field does not announce more data than has been written to the buffer. This should have been fixed with CVE-2011-1161 long ago, but apparently a correct version of that patch never made it into the kernel.

serial: 8250_fintek: Fix finding base_port with activated SuperIO

2017-11-24T07:37:04+00:00

commit fd97e66c5529046e989a0879c3bb58fddb592c71 upstream. The SuperIO will be configured at boot time by BIOS, but some BIOS will not deactivate the SuperIO when the end of configuration. It'll lead to mismatch for pdata->base_port in probe_setup_port(). So we'll deactivate all SuperIO before activate special base_port in fintek_8250_enter_key(). Tested on iBASE MI802.

serial: omap: Fix EFR write on RTS deassertion

2017-11-24T07:37:04+00:00

commit 2a71de2f7366fb1aec632116d0549ec56d6a3940 upstream. Commit 348f9bb31c56 ("serial: omap: Fix RTS handling") sought to enable auto RTS upon manual RTS assertion and disable it on deassertion. However it seems the latter was done incorrectly, it clears all bits in the Extended Features Register *except* auto RTS.

fealnx: Fix building error on MIPS

[ Upstream commit cc54c1d32e6a4bb3f116721abf900513173e4d02 ] This patch try to fix the building error on MIPS. The reason is MIPS has already defined the LONG macro, which conflicts with the LONG enum in drivers/net/ethernet/fealnx.c. Signed-off-by: Huacai Chen Signed-off-by: David S.

net: cdc_ncm: GetNtbFormat endian fix

2017-11-24T07:37:03+00:00

[ Upstream commit 6314dab4b8fb8493d810e175cb340376052c69b6 ] The GetNtbFormat and SetNtbFormat requests operate on 16 bit little endian values. We get away with ignoring this most of the time, because we only care about USB_CDC_NCM_NTB16_FORMAT which is 0x0000. This fails for USB_CDC_NCM_NTB32_FORMAT. Fix comparison between LE value from device and constant by converting the constant to LE.

vxlan: fix the issue that neigh proxy blocks all icmpv6 packets

2017-11-24T07:37:03+00:00

[ Upstream commit 8bff3685a4bbf175a96bc6a528f13455d8d38244 ] Commit f1fb08f6337c ("vxlan: fix ND proxy when skb doesn't have transport header offset") removed icmp6_code and icmp6_type check before calling neigh_reduce when doing neigh proxy. It means all icmpv6 packets would be blocked by this, not only ns packet. In Jianlin's env, even ping6 couldn't work through it. This patch is to bring the icmp6_code and icmp6_type check back and also removed the same check from neigh_reduce().

commit 67f7b2781fafcc0f52464880154b320fea1ae982 upstream. The controller is typically freed as part of device_unregister() so store the bus id before deregistration to avoid use-after-free when the id is later released.

staging: rtl8188eu: Revert 4 commits breaking ARP

2017-11-21T08:49:24+00:00

commit 66d32fdcbf03851724a8b551d490ae1ddfe6eef2 upstream. Commit 2ba8444c97b1 ("staging:r8188eu: move IV/ICV trimming into decrypt() and also place it after rtl88eu_mon_recv_hook()") breaks ARP. After this commit ssh-ing to a laptop with r8188eu wifi no longer works if the machine connecting has never communicated with the laptop before. This is 100% reproducable using "arp -d && ssh " to ssh to a laptop with r8188eu wifi. This commit reverts 4 commits in total: 1. Commit 79650ffde38e ("staging:r8188eu: trim IV/ICV fields in validate_recv_data_frame()") This commit depends on 2 of the other commits being reverted. 2. Commit 02b19b4c4920 ("staging:r8188eu: inline unprotect_frame() in mon_recv_decrypted_recv()") The inline code is wrong the un-inlined version contains: if (skb->len < hdr_len + iv_len + icv_len) return; ... Where as the inline-ed code introduced by this commit does: if (skb->len < hdr_len + iv_len + icv_len) { ... Note the same check, but now to actually continue doing ... instead of to not do it, so this commit is no good. 3. Commit d86e16da6a5d ("staging:r8188eu: use different mon_recv_decrypted() inside rtl88eu_mon_recv_hook() and rtl88eu_mon_xmit_hook().") This commit introduced a 1:1 copy of a function so that one of the 2 copies can be modified in the 2 commits we're already reverting. 4. Commit 2ba8444c97b1 ("staging:r8188eu: move IV/ICV trimming into decrypt() and also place it after rtl88eu_mon_recv_hook()") This is the commit actually breaking ARP. Note this commit is a straight-forward squash of the revert of these 4 commits, without any changes. Cc: Ivan Safonov Signed-off-by: Hans de Goede Signed-off-by: Greg Kroah-Hartman
