bcm4378 and bcm4387 claim to support LE Coded PHY but fail to pair (reliably) with BLE devices if it is enabled. On bcm4378 pairing usually succeeds after 2-3 tries. On bcm4387 pairing appears to be completely broken.

The __hci_cmd_sync() function doesn't return NULL. Checking for NULL doesn't make the code safer, it just confuses people. When a function returns both error pointers and NULL then generally the NULL is a kind of success case. For example, maybe we look up an item then errors mean we ran out of memory but NULL means the item is not found. Or if we request a feature, then error pointers mean that there was an error but NULL means that the feature has been deliberately turned off. In this code it's different. The NULL is handled as if there is a bug in __hci_cmd_sync() where it accidentally returns NULL instead of a proper error code. This was done consistently until commit 9e14606d ("Bluetooth: msft: Extended monitor tracking by address filter") which deleted the work around for the potential future bug and treated NULL as success. Predicting potential future bugs is complicated, but we should just fix them instead of working around them. Instead of debating whether NULL is failure or success, let's just say it's currently impossible and delete the dead code. Signed-off-by:

Currently the CIS bit that can be set by the host is set for any device that has CIS or BIS support. In reality, devices that support BIS may not allow that bit to be set and so, the HCI bring up fails for them. This commit fixes this by only setting the bit for CIS capable devices. Signed-off-by:

This enables a broadcast sink to be informed if the PA it has synced with is associated with an encrypted BIG, by retrieving the socket QoS and checking the encryption field. After PA sync has been successfully established and the first BIGInfo advertising report is received, a new hcon is added and notified to the ISO layer. The ISO layer sets the encryption field of the socket and hcon QoS according to the encryption parameter of the BIGInfo advertising report event. After that, the userspace is woken up, and the QoS of the new PA sync socket can be read, to inspect the encryption field and follow up accordingly. Signed-off-by:

This fixes the master BIS cleanup procedure - as opposed to CIS cleanup, no HCI disconnect command should be issued. A master BIS should only be terminated by disabling periodic and extended advertising, and terminating the BIG. In case of a Broadcast Receiver, all BIS and PA connections can be cleaned up by calling hci_conn_failed, since it contains all function calls that are necessary for successful cleanup.

Commit a243ecc3 ("net: mdio: xgene: Use device_get_match_data()") dropped the unconditional use of xgene_mdio_of_match resulting in this warning: drivers/net/mdio/mdio-xgene.c:303:34: warning: unused variable 'xgene_mdio_of_match' [-Wunused-const-variable] The fix is to drop of_match_ptr() which is not necessary because DT is always used for this driver (well, it could in theory support ACPI only, but CONFIG_OF is always enabled for arm64).

checkpatch gets confused and treats __attribute__ as a function call. It complains about white space before "(": WARNING:SPACING: space prohibited between function name and open parenthesis '(' + struct netdev_queue_get_rsp obj __attribute__ ((aligned (8))); No spaces wins in the kernel: $ git grep 'attribute__((.*aligned(' | wc -l 480 $ git grep 'attribute__ ((.*aligned (' | wc -l 110 $ git grep 'attribute__ ((.*aligned(' | wc -l 94 $ git grep 'attribute__((.*aligned (' | wc -l 63 So, whatever, change the codegen. Note that checkpatch also thinks we should use __aligned(), but this is user space code.

Prior to commit 1a074f76 ("tls: also use init_prot_info in tls_set_device_offload"), setting TLS_HW on TX didn't touch prot->aad_size and prot->tail_size. They are set to 0 during context allocation (tls_prot_info is embedded in tls_context, kzalloc'd by tls_ctx_create). When the RX key is configured, tls_set_sw_offload is called (for both TLS_SW and TLS_HW). If the TX key is configured in TLS_HW mode after the RX key has been installed, init_prot_info will now overwrite the correct values of aad_size and tail_size, breaking SW decryption and causing -EBADMSG errors to be returned to userspace. Since TLS_HW doesn't use aad_size and tail_size at all (for TLS1.2, tail_size is always 0, and aad_size is equal to TLS_HEADER_SIZE + rec_seq_size), we can simply drop this hunk.

Eric Dumazet says: ==================== tcp: add optional usec resolution to TCP TS As discussed in various public places in 2016, Google adopted usec resolution in RFC 7323 TS values, at Van Jacobson suggestion. Goals were : 1) better observability of delays in networking stacks/fabrics. 2) better disambiguation of events based on TSval/ecr values. 3) building block for congestion control modules needing usec resolution. Back then we implemented a schem based on private SYN options to safely negotiate the feature. For upstream submission, we chose to use a much simpler route attribute because this feature is probably going to be used in private networks. ip route add 10/8 ... features tcp_usec_ts References: https://www.ietf.org/proceedings/97/slides/slides-97-tcpm-tcp-options-for-low-latency-00.pdf https://datatracker.ietf.org/doc/draft-wang-tcpm-low-latency-opt/ First two patches are fixing old minor bugs and might be taken by stable teams (thanks to appropriate Fixes: tags) ==================== Acked-by:

Back in 2015, Van Jacobson suggested to use usec resolution in TCP TS values. This has been implemented in our private kernels. Goals were : 1) better observability of delays in networking stacks. 2) better disambiguation of events based on TSval/ecr values. 3) building block for congestion control modules needing usec resolution. Back then we implemented a schem based on private SYN options to negotiate the feature. For upstream submission, we chose to use a route attribute, because this feature is probably going to be used in private networks [1] [2]. ip route add 10/8 ... features tcp_usec_ts Note that RFC 7323 recommends a "timestamp clock frequency in the range 1 ms to 1 sec per tick.", but also mentions "the maximum acceptable clock frequency is one tick every 59 ns." [1] Unfortunately RFC 7323 5.5 (Outdated Timestamps) suggests to invalidate TS.Recent values after a flow was idle for more than 24 days. This is the part making usec_ts a problem for peers following this recommendation for long living idle flows. [2] Attempts to standardize usec ts went nowhere: https://www.ietf.org/proceedings/97/slides/slides-97-tcpm-tcp-options-for-low-latency-00.pdf https://datatracker.ietf.org/doc/draft-wang-tcpm-low-latency-opt/Signed-off-by:

tcp_paws_check() uses TCP_PAWS_24DAYS constant to detect if TCP TS values might have wrapped after a long idle period. This mechanism is described in RFC 7323 5.5 (Outdated Timestamps) TCP_PAWS_24DAYS value was based on the assumption of a clock of 1 Khz. As we want to adopt a 1 Mhz clock in the future, we reduce this constant. Signed-off-by:

It delivers current TCP time stamp in ms unit, and is used in place of confusing tcp_time_stamp_raw() It is the same family than tcp_clock_ns() and tcp_clock_ms(). tcp_time_stamp_raw() will be replaced later for TSval contexts with a more descriptive name. Signed-off-by:

cookie_init_timestamp() is supposed to return a 64bit timestamp suitable for both TSval determination and setting of skb->tstamp. Unfortunately it uses 32bit fields and overflows after 2^32 * 10^6 nsec (~49 days) of uptime. Generated TSval are still correct, but skb->tstamp might be set far away in the past, potentially confusing other layers. tcp_ns_to_ts() is changed to return a full 64bit value, ts and ts_now variables are changed to u64 type, and TSMASK is removed in favor of shifts operations. While we are at it, change this sequence: ts >>= TSBITS; ts--; ts <<= TSBITS; ts |= options; to: ts -= (1UL << TSBITS); Fixes: 9a568de4 ("tcp: switch TCP TS option (RFC 7323) to 1ms clock") Signed-off-by:

Beniamino Galvani says: ==================== net: consolidate IPv6 route lookup for UDP tunnels At the moment different UDP tunnels rely on different functions for IPv6 route lookup, and those functions all implement the same logic. Extend the generic lookup function so that it is suitable for all UDP tunnel implementations, and then adapt bareudp, geneve and vxlan to use it. This is similar to what already done for IPv4. ==================== Signed-off-by: -

The route lookup can be done now via generic function udp_tunnel6_dst_lookup() to replace the custom implementation in vxlan6_get_route(). This is similar to what already done for IPv4 in commit 6f19b2c1 ("vxlan: use generic function for tunnel IPv4 route lookup"). Suggested-by:

We want to make the function more generic so that it can be used by other UDP tunnel implementations such as geneve and vxlan. To do that, add the following arguments: - source and destination UDP port; - ifindex of the output interface, needed by vxlan; - the tos, because in some cases it is not taken from struct ip_tunnel_info (for example, when it's inherited from the inner packet); - the dst cache, because not all tunnel types (e.g. vxlan) want to use the one from struct ip_tunnel_info. With these parameters, the function no longer needs the full struct ip_tunnel_info as argument and we can pass only the relevant part of it (struct ip_tunnel_key). This is similar to what already done for IPv4 in commit 72fc68c6 ("ipv4: add new arguments to udp_tunnel_dst_lookup()"). Suggested-by:
