2022-07-12devlink: Remove unused functions devlink_rate_leaf_create/destroyMoshe Shemesh
The previous patch removed the last usage of the functions devlink_rate_leaf_create() and devlink_rate_nodes_destroy(). Thus, remove these function from devlink API.

2022-07-12net/mlx5: Use devl_ API in mlx5_esw_devlink_sf_port_registerMoshe Shemesh
The function mlx5_esw_devlink_sf_port_register() calls devlink_port_register() and devlink_rate_leaf_create(). Use devl_ API to call devl_port_register() and devl_rate_leaf_create() accordingly and add devlink instance lock in driver paths to this function. Similarly, use devl_ API to call devl_port_unregister() and devl_rate_leaf_destroy() in mlx5_esw_devlink_sf_port_unregister() and ensure locking devlink instance lock on all the paths to this function too. This will be used by the downstream patch to invoke mlx5_devlink_eswitch_mode_set() with devlink lock held. Note this patch is taking devlink lock on mlx5_devlink_sf_port_new/del() which are devlink callbacks for port_new/del(). We will take these locks off once these callbacks will be locked by devlink too.

2022-07-12net/mlx5: Remove devl_unlock from mlx5_eswtich_mode_callback_enterMoshe Shemesh
The function mlx5_eswtich_mode_callback_enter() was added as a temporary workaround once devlink instance lock was added to devlink eswitch callbacks. However, code review and testing show that all the callbacks part to eswitch_mode_set don't take devlink instance lock in any flow and so unlocking devlink instance lock while entering these functions is not needed. Remove devl_lock from mlx5_eswtich_mode_callback_enter() and devl_unlock from mlx5_eswtich_mode_callback_exit(). Also remove the functions mlx5_eswtich_mode_callback_enter()/exit() as they are not needed any more. The callback eswitch_mode_set will be treated separately in the following patches.

2022-07-11amd-xgbe: fix clang -Wformat warningsJustin Stitt
When building with Clang we encounter the following warning: | drivers/net/ethernet/amd/xgbe/xgbe-dcb.c:234:42: error: format specifies | type 'unsigned char' but the argument has type '__u16' (aka 'unsigned | short') [-Werror,-Wformat] pfc->pfc_cap, pfc->pfc_en, pfc->mbc, | pfc->delay); pfc->pfc_cap , pfc->pfc_cn, pfc->mbc are all of type `u8` while pfc->delay is of type `u16`. The correct format specifiers `%hh[u|x]` were used for the first three but not for pfc->delay, which is causing the warning above. Variadic functions (printf-like) undergo default argument promotion. Documentation/core-api/printk-formats.rst specifically recommends using the promoted-to-type's format flag. In this case `%d` (or `%x` to maintain hex representation) should be used since both u8's and u16's are fully representable by an int. Moreover, C11 6.3.1.1 states: (https://www.open-std.org/jtc1/sc22/wg14/www/docs/n1548.pdf) `If an int can represent all values of the original type ..., the value is converted to an int; otherwise, it is converted to an unsigned int.

2022-07-11net: Find dst with sk's xfrm policy not ctl_sksewookseo
If we set XFRM security policy by calling setsockopt with option IPV6_XFRM_POLICY, the policy will be stored in 'sock_policy' in 'sock' struct. However tcp_v6_send_response doesn't look up dst_entry with the actual socket but looks up with tcp control socket. This may cause a problem that a RST packet is sent without ESP encryption & peer's TCP socket can't receive it. This patch will make the function look up dest_entry with actual socket, if the socket has XFRM policy(sock_policy), so that the TCP response packet via this function can be encrypted, & aligned on the encrypted TCP socket. Tested: We encountered this problem when a TCP socket which is encrypted in ESP transport mode encryption, receives challenge ACK at SYN_SENT state. After receiving challenge ACK, TCP needs to send RST to establish the socket at next SYN try. But the RST was not encrypted & peer TCP socket still remains on ESTABLISHED state. So we verified this with test step as below. [Test step] 1. Making a TCP state mismatch between client(IDLE) & server(ESTABLISHED). 2. Client tries a new connection on the same TCP ports(src & dst). 3. Server will return challenge ACK instead of SYN,ACK. 4. Client will send RST to server to clear the SOCKET. 5. Client will retransmit SYN to server on the same TCP ports. [Expected result] The TCP connection should be established.

2022-07-09af_unix: fix unix_sysctl_register() error pathEric Dumazet
We want to kfree(table) if @table has been kmalloced, ie for non initial network namespace. Fixes: 849d5aa3a1d8 ("af_unix: Do not call kmemdup() for init_net's sysctl table.")

2022-07-09Merge branch 'mptcp-selftest-improvements-and-header-tweak'David S. Miller
Mat Martineau says: ==================== mptcp: Self test improvements and a header tweak Patch 1 moves a definition to a header so it can be used in a struct declaration. Patch 2 adjusts a time threshold for a selftest that runs much slower on debug kernels (and even more on slow CI infrastructure), to reduce spurious failures. Patches 3 & 4 improve userspace PM test coverage. Patches 5 & 6 clean up output from a test script and selftest helper tool. ==================== Signed-off-by: David S. Miller <davem@davemloft.net>
2022-07-09selftests: mptcp: update pm_nl_ctl usage headerGeliang Tang
The usage header of pm_nl_ctl command doesn't match with the context. So this patch adds the missing userspace PM keywords 'ann', 'rem', 'csf', 'dsf', 'events' and 'listen' in it.

2022-07-09selftests: mptcp: avoid Terminated messages in userspace_pmGeliang Tang
There're some 'Terminated' messages in the output of userspace pm tests script after killing './pm_nl_ctl events' processes: Created network namespaces ns1, ns2 [OK] ./userspace_pm.sh: line 166: 13735 Terminated ip netns exec "$ns2" ./pm_nl_ctl events >> "$client_evts" 2>&1 ./userspace_pm.sh: line 172: 13737 Terminated ip netns exec "$ns1" ./pm_nl_ctl events >> "$server_evts" 2>&1 Established IPv4 MPTCP Connection ns2 => ns1 [OK] ./userspace_pm.sh: line 166: 13753 Terminated ip netns exec "$ns2" ./pm_nl_ctl events >> "$client_evts" 2>&1 ./userspace_pm.sh: line 172: 13755 Terminated ip netns exec "$ns1" ./pm_nl_ctl events >> "$server_evts" 2>&1 Established IPv6 MPTCP Connection ns2 => ns1 [OK] ADD_ADDR 10.0.2.2 (ns2) => ns1, invalid token [OK] This patch adds a helper kill_wait(), in it using 'wait $pid 2>/dev/null' commands after 'kill $pid' to avoid printing out these Terminated messages. Use this helper instead of using 'kill $pid'.

2022-07-09selftests: mptcp: tweak simult_flows for debug kernelsPaolo Abeni
The mentioned test measures the transfer run-time to verify that the user-space program is able to use the full aggregate B/W. Even on (virtual) link-speed-bound tests, debug kernel can slow down the transfer enough to cause sporadic test failures. Instead of unconditionally raising the maximum allowed run-time, tweak when the running kernel is a debug one, and use some simple/ rough heuristic to guess such scenarios. Note: this intentionally avoids looking for /boot/config-<version> as the latter file is not always available in our reference CI environments.
