From the patch series description:
Several security issues in the 802.11 implementations were found by
Mathy Vanhoef (New York University Abu Dhabi), who has published all
the details at
https://papers.mathyvanhoef.com/usenix2021.pdf
Specifically, the following CVEs were assigned:
* CVE-2020-24586 - Fragmentation cache not cleared on reconnection
* CVE-2020-24587 - Reassembling fragments encrypted under different
keys
* CVE-2020-24588 - Accepting non-SPP A-MSDU frames, which leads to
payload being parsed as an L2 frame under an
A-MSDU bit toggling attack
* CVE-2020-26139 - Forwarding EAPOL from unauthenticated sender
* CVE-2020-26140 - Accepting plaintext data frames in protected
networks
* CVE-2020-26141 - Not verifying TKIP MIC of fragmented frames
* CVE-2020-26142 - Processing fragmented frames as full frames
* CVE-2020-26143 - Accepting fragmented plaintext frames in
protected networks
* CVE-2020-26144 - Always accepting unencrypted A-MSDU frames that
start with RFC1042 header with EAPOL ethertype
* CVE-2020-26145 - Accepting plaintext broadcast fragments as full
frames
* CVE-2020-26146 - Reassembling encrypted fragments with non-consecutive
packet numbers
* CVE-2020-26147 - Reassembling mixed encrypted/plaintext fragments
In general, the scope of these attacks is that they may allow an
attacker to
* inject L2 frames that they can more or less control (depending on the
vulnerability and attack method) into an otherwise protected network;
* exfiltrate (some) network data under certain conditions, this is
specific to the fragmentation issues.
A subset of these issues is known to apply to the Linux IEEE 802.11
implementation (mac80211). Where it is affected, the attached patches
fix the issues, even if not all of them reference the exact CVE IDs.
In addition, driver and/or firmware updates may be necessary, as well
as potentially more fixes to mac80211, depending on how drivers are
using it.
Specifically, for Intel devices, firmware needs to be updated to the
most recently released versions (which was done without any reference
to the security issues) to address some of the vulnerabilities.
To have a single set of patches, I'm also including patches for the
ath10k and ath11k drivers here.
We currently don't have information about how other drivers are, if
at all, affected.

Fixes issue with merged DNS requests in 2.83/2.84 not being
retried on the firsts failed request causing lookup failures.
Also fixes the following security problem in dnsmasq:
* CVE-2021-3448:
If specifiying the source address or interface to be used
when contacting upstream name servers such as:
server=8.8.8.8@1.2.3.4, server=8.8.8.8@1.2.3.4#66 and
server=8.8.8.8@eth0 then all would use the same socket
bound to the explicitly configured port. Now only
server=8.8.8.8@1.2.3.4#66 will use the explicitly
configured port and the others random source ports.
Remove upstreamed patches and update remaining patch.

默认情况下 SSR PLUS DNS结果根本无法缓存(由于引入拒绝ipv6结果导致的问题)，nslookup & dig 延迟每次依然有200-300多.
dnsmasq处设置缓存依然无效，设置TTL也无效，应该是bug。
解决办法是手动指定缓存TTL为最大一小时。域名查询实测有效缓存0延迟。
此变更仅使开启dnsmasq缓存的情况下正常工作。
The can-dev.ko kernel module was moved in kernel 5.4.110 and 5.10.28.

This release of Mbed TLS provides bug fixes and minor enhancements. This
release includes fixes for security issues.
Security fixes:
* Fix a buffer overflow in mbedtls_mpi_sub_abs()
* Fix an errorneous estimation for an internal buffer in
mbedtls_pk_write_key_pem()
* Fix a stack buffer overflow with mbedtls_net_poll() and
mbedtls_net_recv_timeout()
* Guard against strong local side channel attack against base64 tables
by making access aceess to them use constant flow code
