Maxim reports do_tls_getsockopt_no_pad() will always return an error. Indeed looks like refactoring gone wrong - remove err and use value.

2022-07-11NFSD: Decode NFSv4 birth time attributeChuck Lever
NFSD has advertised support for the NFSv4 time_create attribute since commit e377a3e698fb ("nfsd: Add support for the birth time attribute"). Igor Mammedov reports that Mac OS clients attempt to set the NFSv4 birth time attribute via OPEN(CREATE) and SETATTR if the server indicates that it supports it, but since the above commit was merged, those attempts now fail. Table 5 in RFC 8881 lists the time_create attribute as one that can be both set and retrieved, but the above commit did not add server support for clients to provide a time_create attribute. IMO that's a bug in our implementation of the NFSv4 protocol, which this commit addresses. Whether NFSD silently ignores the new birth time or actually sets it is another matter. I haven't found another filesystem service in the Linux kernel that enables users or clients to modify a file's birth time attribute. This commit reflects my (perhaps incorrect) understanding of whether Linux users can set a file's birth time. NFSD will now recognize a time_create attribute but it ignores its value. It clears the time_create bit in the returned attribute bitmask to indicate that the value was not used.

2022-07-11module: kallsyms: Ensure preemption in add_kallsyms() with PREEMPT_RTAaron Tomlin
The commit 08126db5ff73 ("module: kallsyms: Fix suspicious rcu usage") under PREEMPT_RT=y, disabling preemption introduced an unbounded latency since the loop is not fixed. This change caused a regression since previously preemption was not disabled and we would dereference RCU-protected pointers explicitly. That being said, these pointers cannot change. Before kallsyms-specific data is prepared/or set-up, we ensure that the unformed module is known to be unique i.e. does not already exist (see load_module()). Therefore, we can fix this by using the common and more appropriate RCU flavour as this section of code can be safely preempted.

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.

Reason for this subtle difference to me is unknown. 2) packet logging is not correct for ARP and IP packets, from the ARP family and netdev/egress respectively.

A pending packet uses a cookie as an unique key, but it can be duplicated because it didn't use atomic operators. And also, a pending packet can be null in hwsim_tx_info_frame_received_nl due to race condition with mac80211_hwsim_stop. For this, * Use an atomic type and operator for a cookie * Add a lock around the loop for pending packets Signed-off-by: Jeongik Cha <jeongik@google.com> Link: https://lore.kernel.org/r/20220704084354.3556326-1-jeongik@google.com Signed-off-by: Johannes Berg <johannes.berg@intel.com>
2022-07-11wifi: mac80211: Use the bitmap API to allocate bitmapsChristophe JAILLET
Use bitmap_zalloc()/bitmap_free() instead of hand-writing them. It is less verbose and it improves the semantic.

2022-07-11wifi: mac80211: fix center freq calculation in ieee80211_chandef_downgradeMeiChia Chiu
When mac80211 downgrades working bandwidth, the center_freq and center_freq1 need to be recalculated. There is a typo in the case of downgrading bandwidth from 320MHz to 160MHz which would cause a wrong frequency value.

2022-07-11wifi: nl80211: fix sending link ID info of associated BSSVeerendranath Jakkam
commit dd374f84baec ("wifi: nl80211: expose link ID for associated BSSes") used a top-level attribute to send link ID of the associated BSS in the nested attribute NL80211_ATTR_BSS. But since NL80211_ATTR_BSS is a nested attribute of the attributes defined in enum nl80211_bss, define a new attribute in enum nl80211_bss and use it for sending the link ID of the BSS.
