When we have a single image (same firmware image for INIT and OPERATIONAL), we couldn't load the driver and register to the stack if we had hardware RF-Kill asserted. Fix this. This required a few changes: 1) Run the firmware as part of the INIT phase even if its ucode_type is not IWL_UCODE_INIT. 2) Send the commands that are sent to the unified image in INIT flow even in RF-Kill. 3) Don't ask the transport to stop the hardware upon RF-Kill interrupt if the RF-Kill is asserted. 4) Allow the RF-Kill interrupt to take us out of L1A so that the RF-Kill interrupt will be received by the host (to enable the radio).

This debugfs file is really old, and cannot work properly since the unified image support. Rather than trying to make it work, which is difficult now due to multiple images (LMAC/UMAC etc.) just remove it - we no longer need it since we properly do a FW coredump even in D3 cases. Signed-off-by:

mwifiex_update_bss_desc_with_ie() calls memcpy() unconditionally in a couple places without checking the destination size. Since the source is given from user-space, this may trigger a heap buffer overflow. Fix it by putting the length check before performing memcpy(). This fix addresses CVE-2019-3846. Reported-by:

The new rssi_level should be stored in si, otherwise the rssi_level will never be updated and get a wrong RA mask, which is calculated by the rssi level If a wrong RA mask is chosen, the firmware will pick some *bad rates*. The most hurtful scene will be in *noisy environment*, such as office or public area with many APs and users. The latency would be high and the overall throughput would be only half or less.

Jakub Kicinski says: ==================== net/tls: two fixes for rx_list pre-handling tls_sw_recvmsg() had been modified to cater better to async decrypt. Partially read records now live on the rx_list. Data is copied from this list before the old do {} while loop, and the not included correctly in deciding whether to sleep or not and lowat threshold handling. These modifications, unfortunately, added some bugs. First patch fixes lowat - we need to calculate the threshold early and make sure all copied data is compared to the threshold, not just the freshly decrypted data. Third patch fixes sleep - if data is picked up from rx_list and no flags are set, we should not put the process to sleep, but rather return the partial read. Patches 2 and 4 add test cases for these bugs, both will cause a sleep and test timeout before the fix. ==================== Signed-off-by: -

When tls_sw_recvmsg() partially copies a record it pops that record from ctx->recv_pkt and places it on rx_list. Next iteration of tls_sw_recvmsg() reads from rx_list via process_rx_list() before it enters the decryption loop. If there is no more records to be read tls_wait_data() will put the process on the wait queue and got to sleep. This is incorrect, because some data was already copied in process_rx_list(). In case of RPC connections process may never get woken up, because peer also simply blocks in read(). I think this may also fix a similar issue when BPF is at play, because after __tcp_bpf_recvmsg() returns some data we subtract it from len and use continue to restart the loop, but len could have just reached 0, so again we'd sleep unnecessarily. That's added by: commit d3b18ad3 ("tls: add bpf support to sk_msg handling") Fixes: 692d7b5d ("tls: Fix recvmsg() to be able to peek across multiple records") Reported-by:

Jakub Kicinski authored
If some of the data came from the previous record, i.e. from the rx_list it had already been decrypted, so it's not counted towards the "decrypted" variable, but the "copied" variable. Take that into account when checking lowat. When calculating lowat target we need to pass the original len. E.g. if lowat is at 80, len is 100 and we had 30 bytes on rx_list target would currently be incorrectly calculated as 70, even though we only need 50 more bytes to make up the 80.

Once in a while, with just the right timing, 802.3ad slaves will fail to properly initialize, winding up in a weird state, with a partner system mac address of 00:00:00:00:00:00. This started happening after a fix to properly track link_failure_count tracking, where an 802.3ad slave that reported itself as link up in the miimon code, but wasn't able to get a valid speed/duplex, started getting set to BOND_LINK_FAIL instead of BOND_LINK_DOWN. That was the proper thing to do for the general "my link went down" case, but has created a link initialization race that can put the interface in this odd state. The simple fix is to instead set the slave link to BOND_LINK_DOWN again, if the link has never been up (last_link_up == 0), so the link state doesn't bounce from BOND_LINK_DOWN to BOND_LINK_FAIL -- it hasn't failed in this case, it simply hasn't been up yet, and this prevents the unnecessary state change from DOWN to FAIL and getting stuck in an init failure w/o a partner mac.

Function tcf_action_dump() relies on tc_action->order field when starting nested nla to send action data to userspace. This approach breaks in several cases: - When multiple filters point to same shared action, tc_action->order field is overwritten each time it is attached to filter. This causes filter dump to output action with incorrect attribute for all filters that have the action in different position (different order) from the last set tc_action->order value. - When action data is displayed using tc action API (RTM_GETACTION), action order is overwritten by tca_action_gd() according to its position in resulting array of nl attributes, which will break filter dump for all filters attached to that shared action that expect it to have different order value. Don't rely on tc_action->order when dumping actions. Set nla according to action position in resulting array of actions instead. Signed-off-by:

This reverts commit 2391b003 which has introduced regression. Now SGE's BAR2 Doorbell/GTS Page Size is interpreted correctly in the firmware itself by using actual host page size. Hence previous commit needs to be reverted. Signed-off-by:

Fix the clk mismatch in the error path "failed_reset" because below error path will disable clk_ahb and clk_ipg directly, it should use pm_runtime_put_noidle() instead of pm_runtime_put() to avoid to call runtime resume callback. Reported-by:

Pablo Neira Ayuso says: ==================== Netfilter/IPVS fixes for net The following patchset contains Netfilter/IPVS fixes for your net tree: 1) Fix crash when dumping rules after conversion to RCU, from Florian Westphal. 2) Fix incorrect hook reinjection from nf_queue in case NF_REPEAT, from Jagdish Motwani. 3) Fix check for route existence in fib extension, from Phil Sutter. 4) Fix use after free in ip_vs_in() hook, from YueHaibing. 5) Check for veth existence from netfilter selftests, from Jeffrin Jose T. 6) Checksum corruption in UDP NAT helpers due to typo, from Florian Westphal. 7) Pass up packets to classic forwarding path regardless of IPv4 DF bit, patch for the flowtable infrastructure from Florian. 8) Set liberal TCP tracking for flows that are placed in the flowtable, in case they need to go back to classic forwarding path, also from Florian. 9) Don't add flow with sequence adjustment to flowtable, from Florian. 10) Skip IPv4 options from IPv6 datapath in flowtable, from Florian. 11) Add selftest for the flowtable infrastructure, from Florian. ==================== Signed-off-by: -

VLAN flows never get offloaded unless ivlan_vld is set in filter spec. It's not compulsory for vlan_ethtype to be set. So, always enable ivlan_vld bit for offloading VLAN flows regardless of vlan_ethtype is set or not. Fixes: ad9af3e0 (cxgb4: add tc flower match support for vlan) Signed-off-by:

Don't prune the master node in the hsr_prune_nodes function. Neither time_in[HSR_PT_SLAVE_A] nor time_in[HSR_PT_SLAVE_B] will ever be updated by hsr_register_frame_in for the master port. Thus, the master node will be repeatedly pruned leading to repeated packet loss. This bug never appeared because the hsr_prune_nodes function was only called once. Since commit 5150b45f ("net: hsr: Fix node prune function for forget time expiry") this issue is fixed unveiling the issue described above.

The flow_rule is only used when configuring the classification tables, and should be free'd once we're done using it. The current code only frees it in the error path. Fixes: 90b509b3 ("net: mvpp2: cls: Add Classification offload support") Signed-off-by:
