2020-04-18tipc: Fix potential tipc_aead refcnt leak in tipc_crypto_rcvXiyu Yang
tipc_crypto_rcv() invokes tipc_aead_get(), which returns a reference of the tipc_aead object to "aead" with increased refcnt. When tipc_crypto_rcv() returns, the original local reference of "aead" becomes invalid, so the refcount should be decreased to keep refcount balanced. The issue happens in one error path of tipc_crypto_rcv(). When TIPC message decryption status is EINPROGRESS or EBUSY, the function forgets to decrease the refcnt increased by tipc_aead_get() and causes a refcnt leak. Fix this issue by calling tipc_aead_put() on the error path when TIPC message decryption status is EINPROGRESS or EBUSY.

2020-04-18net: netrom: Fix potential nr_neigh refcnt leak in nr_add_nodeXiyu Yang
nr_add_node() invokes nr_neigh_get_dev(), which returns a local reference of the nr_neigh object to "nr_neigh" with increased refcnt. When nr_add_node() returns, "nr_neigh" becomes invalid, so the refcount should be decreased to keep refcount balanced. The issue happens in one normal path of nr_add_node(), which forgets to decrease the refcnt increased by nr_neigh_get_dev() and causes a refcnt leak. It should decrease the refcnt before the function returns like other normal paths do. Fix this issue by calling nr_neigh_put() before the nr_add_node() returns.

2020-04-18ALSA: hda/realtek - Fix unexpected init_amp overrideTakashi Iwai
The commit 1c76aa5fb48d ("ALSA: hda/realtek - Allow skipping spec->init_amp detection") changed the way to assign spec->init_amp field that specifies the way to initialize the amp. Along with the change, the commit also replaced a few fixups that set spec->init_amp in HDA_FIXUP_ACT_PROBE with HDA_FIXUP_ACT_PRE_PROBE. This was rather aligning to the other fixups, and not supposed to change the actual behavior. However, this change turned out to cause a regression on FSC S7020, which hit exactly the above. The reason was that there is still one place that overrides spec->init_amp after HDA_FIXUP_ACT_PRE_PROBE call, namely in alc_ssid_check(). This patch fixes the regression by adding the proper spec->init_amp override check, i.e. verifying whether it's still ALC_INIT_UNDEFINED.

2020-04-17igc: Fix default MAC address filter overrideAndre Guedes
This patch fixes a bug when the user adds the first MAC address filter via ethtool NFC mechanism. When the first MAC address filter is added, it overwrites the default MAC address filter configured at RAL[0] and RAH[0]. As consequence, frames addressed to the interface MAC address are not sent to host anymore. This patch fixes the bug by calling igc_set_default_mac_filter() during adapter init so the position 0 of adapter->mac_table[] is assigned to the default MAC address.

This patch fixes some register overwriting when dumping registers via ethtool. We have a total of 16 RAL registers, starting at offset 139. So RAH offset should be 139 + 16 = 155, not 145. As result some RAL registers are overwritten. Likewise, RAH registers are also overwritten by TDBAL, TDBAH, TDLEN, and TDH registers. To fix this bug while preserving the ABI, this patch re-writes RAL and RAH registers at the end of 'regs_buff' and bumps regs->version. It also removes some pointless comments in the middle of igc_set_regs().

2020-04-17e1000: Distribute switch variables for initializationKees Cook
Variables declared in a switch statement before any case statements cannot be automatically initialized with compiler instrumentation (as they are not part of any execution flow). With GCC's proposed automatic stack variable initialization feature, this triggers a warning (and they don't get initialized). Clang's automatic stack variable initialization (via CONFIG_INIT_STACK_ALL=y) doesn't throw a warning, but it also doesn't initialize such variables[1]. Note that these warnings (or silent skipping) happen before the dead-store elimination optimization phase, so even when the automatic initializations are later elided in favor of direct initializations, the warnings remain. To avoid these problems, move such variables into the "case" where they're used or lift them up into the main function body. drivers/net/ethernet/intel/e1000/e1000_main.c: In function ‘e1000_xmit_frame’: drivers/net/ethernet/intel/e1000/e1000_main.c:3143:18: warning: statement will never be executed [-Wswitch-unreachable] 3143 | unsigned int pull_size; | ^~~~~~~~~ [1] https://bugs.llvm.org/show_bug.cgi?id=44916 Signed-off-by: Kees Cook <keescook@chromium.org> Tested-by: Aaron Brown <aaron.f.brown@intel.com> Signed-off-by: Jeff Kirsher <jeffrey.t.kirsher@intel.com>
2020-04-17igc: Add support for ETF offloadingVinicius Costa Gomes
This adds support for ETF offloading for the i225 controller. For i225, the LaunchTime feature is almost a subset of the Qbv feature. The main change from the i210 is that the launchtime of each packet is specified as an offset applied to the BASET register. BASET is automatically incremented each cycle. For i225, the approach chosen is to re-use most of the setup used for taprio offloading. With a few changes: - The more or less obvious one is that when ETF is enabled, we should set add the expected launchtime to the (advanced) transmit descriptor; - The less obvious, is that when taprio offloading is not enabled, we add a dummy schedule (all queues are open all the time, with a cycle time of 1 second).

2020-04-17igc: Add support for taprio offloadingVinicius Costa Gomes
Adds support for translating taprio schedules into i225 cycles. This will allow schedules to run in the hardware, making the schedules enforcement more precise and saving CPU time. Right now, the only simple schedules are allowed, complex schedules are rejected. "simple" in this context are schedules that each HW queue is opened and closed only once in each cycle. Changing schedules is still not supported as well.

2020-04-17igc: Add GSO partial supportSasha Neftin
Partial generic segmentation offload is a hybrid between TSO and GSO. What is effectively does is take advantage of certain traits of TCP and tunnels so that instead of having to rewrite the packet headers for each segment only in the inner-most transport header and possible the outer-most network header need to be updated. This allows devices that do not support tunnel offload or tunnels offloads with checksum to still make use of segmentation.
