+
+Currently, reinstallations of the PTK are prevented by (1) assuring the

+is only installed once. This patch makes it more explicit that point (1)
+is required to prevent key reinstallations. At the same time, this patch
+hardens wpa_supplicant such that future changes do not accidentally
+break this property.

+Subject: [PATCH] Optional AP side workaround for key reinstallation attacks
+
+This adds a new hostapd configuration parameter
+wpa_disable_eapol_key_retries=1 that can be used to disable
+retransmission of EAPOL-Key frames that are used to install
+keys (EAPOL-Key message 3/4 and group message 1/2). This is
+similar to setting wpa_group_update_count=1 and
+wpa_pairwise_update_count=1, but with no impact to message 1/4
+retries and with extended timeout for messages 4/4 and group
+message 2/2 to avoid causing issues with stations that may use
+aggressive power saving have very long time in replying to the
+EAPOL-Key messages.
+
+This option can be used to work around key reinstallation attacks
+on the station (supplicant) side in cases those station devices
+cannot be updated for some reason. By removing the
+retransmissions the attacker cannot cause key reinstallation with
+a delayed frame transmission. This is related to the station side
+vulnerabilities CVE-2017-13077, CVE-2017-13078, CVE-2017-13079,
+CVE-2017-13080, and CVE-2017-13081.
+
+This workaround might cause interoperability issues and reduced
+robustness of key negotiation especially in environments with
+heavy traffic load due to the number of attempts to perform the
+key exchange is reduced significantly. As such, this workaround

++# Workaround for key reinstallation attacks
++#
++# This parameter can be used to disable retransmission of EAPOL-Key frames that
++# are used to install keys (EAPOL-Key message 3/4 and group message 1/2). This
++# is similar to setting wpa_group_update_count=1 and

++# extended timeout on the response to avoid causing issues with stations that
++# may use aggressive power saving have very long time in replying to the
++# EAPOL-Key messages.
++#
++# This option can be used to work around key reinstallation attacks on the
++# station (supplicant) side in cases those station devices cannot be updated
++# for some reason. By removing the retransmissions the attacker cannot cause
++# key reinstallation with a delayed frame transmission. This is related to the
++# station side vulnerabilities CVE-2017-13077, CVE-2017-13078, CVE-2017-13079,
++# CVE-2017-13080, and CVE-2017-13081.

+Subject: [PATCH 01/10] tcp: tsq: add tsq_flags / tsq_enum
+
+This is a cleanup, to ease code review of following patches.
+
+Old 'enum tsq_flags' is renamed, and a new enumeration is added
+with the flags used in cmpxchg() operations as opposed to
+single bit operations.

+Instead of atomically clear TSQ_THROTTLED and atomically set TSQ_QUEUED
+bits, use one cmpxchg() to perform a single locked operation.
+
+Since the following patch will also set TCP_TSQ_DEFERRED here,

+Subject: [PATCH 03/10] tcp: tsq: add shortcut in tcp_tasklet_func()
+
+Under high stress, I've seen tcp_tasklet_func() consuming
+~700 usec, handling ~150 tcp sockets.
+
+By setting TCP_TSQ_DEFERRED in tcp_wfree(), we give a chance
+for other cpus/threads entering tcp_write_xmit() to grab it,
+allowing tcp_tasklet_func() to skip sockets that already did
+an xmit cycle.
+
+In the future, we might give to ACK processing an increased
+budget to reduce even more tcp_tasklet_func() amount of work.

+
+Group fields used in TX path, and keep some cache lines mostly read

+
+Gained two 4 bytes holes on 64bit arches.
+
+Added a place holder for tcp tsq_flags, next to sk_wmem_alloc
+to speed up tcp_wfree() in the following patch.
+
+I have not added ____cacheline_aligned_in_smp, this might be done later.
+I prefer doing this once inet and tcp/udp sockets reorg is also done.
+
+Tested with both TCP and UDP.
+
+UDP receiver performance under flood increased by ~20 % :
+Accessing sk_filter/sk_wq/sk_napi_id no longer stalls because sk_drops
+was moved away from a critical cache line, now mostly read and shared.

+Subject: [PATCH 08/10] tcp: tsq: move tsq_flags close to sk_wmem_alloc
+
+tsq_flags being in the same cache line than sk_wmem_alloc
+makes a lot of sense. Both fields are changed from tcp_wfree()
+and more generally by various TSQ related functions.
+
+Prior patch made room in struct sock and added sk_tsq_flags,
+this patch deletes tsq_flags from struct tcp_sock.

+Subject: [PATCH 09/10] tcp: add a missing barrier in tcp_tasklet_func()
+
+Madalin reported crashes happening in tcp_tasklet_func() on powerpc64
+
+Before TSQ_QUEUED bit is cleared, we must ensure the changes done
+by list_del(&tp->tsq_node); are committed to memory, otherwise
+corruption might happen, as an other cpu could catch TSQ_QUEUED
+clearance too soon.
+
+We can notice that old kernels were immune to this bug, because
+TSQ_QUEUED was cleared after a bh_lock_sock(sk)/bh_unlock_sock(sk)
+section, but they could have missed a kick to write additional bytes,
+when NIC interrupts for a given flow are spread to multiple cpus.
+
+Affected TCP flows would need an incoming ACK or RTO timer to add more
+packets to the pipe. So overall situation should be better now.

-Subject: [PATCH 51/70] PCI: designware: Ensure ATU is enabled before IO/conf
- space accesses
-
-Read back the ATU CR2 register to ensure ATU programming is effective
-before any subsequent I/O or config space accesses.
-
-Without this, PCI device enumeration is unreliable.

-Subject: [PATCH 53/70] PCI: designware: Make config accessor override
- checking symmetric
-
-Drivers based on the DesignWare core can override the config read accessors
-by supplying rd_own_conf() and rd_other_conf() function pointers.
-dw_pcie_rd_conf() calls dw_pcie_rd_own_conf() (for accesses to the root
-bus) or dw_pcie_rd_other_conf():
-
-  dw_pcie_rd_conf
-    dw_pcie_rd_own_conf                # if on root bus
-    dw_pcie_rd_other_conf              # if not on root bus
-
-Previously we checked for rd_other_conf() directly in dw_pcie_rd_conf(),
-but we checked for rd_own_conf() in dw_pcie_rd_own_conf().
-
-Check for rd_other_conf() in dw_pcie_rd_other_conf() to make this symmetric
-with the rd_own_conf() checking, and similarly for the write path.
-
-No functional change intended.

-commit 886bc5ceb5cc3ad4b219502d72b277e3c3255a32 upstream
-[context adjustment]
-[remove drivers/pci/host/pcie-qcom.c related changes]
-
-Several DesignWare-based drivers (dra7xx, exynos, imx6, keystone, qcom, and
-spear13xx) had similar loops waiting for the link to come up.
-
-Add a generic dw_pcie_wait_for_link() for use by all these drivers so the
-waiting is done consistently, e.g., always using usleep_range() rather than
-mdelay() and using similar timeouts and retry counts.
-
-Note that this changes the Keystone link training/wait for link strategy,
-so we initiate link training, then wait longer for the link to come up
-before re-initiating link training.

-
-dw_pcie_host_init() looks up host bridge resources, ioremaps them, creates

-programs the Root Complex registers.  The Root Complex may lose power
-during suspend-to-RAM, and when we resume, we want to redo the latter but
-not the former.
-
-Move some Root Complex programming from dw_pcie_host_init() to
-dw_pcie_setup_rc() where it belongs.  DesignWare-based drivers can call
-dw_pcie_setup_rc() in their resume paths.

-[Niklas Cassel <niklas.cassel@axis.com>:  This change moves outbound ATU

-Subject: [PATCH 59/70] PCI: designware: Remove incorrect RC memory base/limit
- configuration
-
-Currently dw_pcie_setup_rc() configures memory base and memory limit in the
-type1 configuration header for the root complex.  In doing so it uses the
-CPU address (pp->mem_base) rather than the bus address (pp->mem_bus_addr).
-This is wrong and it is useless since the configuration is overwritten
-later on when pci_bus_assign_resources() is called.
-
-Remove this configuration from dw_pcie_setup_rc().
