As Arnd Bergmann reported [1], mkimage shows the detailed information of the generated images. I think this should be suppressed by the 'cmd' macro instead of by individual scripts. Insert 'exec >/dev/null;' in order to redirect stdout to /dev/null for silent builds. [Note about this implementation] 'exec >/dev/null;' may look somewhat tricky, but this has a reason. Appending '>/dev/null' at the end of command line is a common way for redirection, so I first tried this: cmd = @set -e; $(echo-cmd) $(cmd_$(1)) >/dev/null ... but it would not work if $(cmd_$(1)) itself contains a redirection. For example, cmd_wrap in scripts/Makefile.asm-generic redirects the output from the 'echo' command into the target file. It would be expanded into: echo "#include " > $@ >/dev/null Then, the target file gets empty because the string will go to /dev/null instead of $@. Next, I tried this: cmd = @set -e; $(echo-cmd) { $(cmd_$(1)); } >/dev/null The form above would be expanded into: { echo "#include " > $@; } >/dev/null This works as expected. However, it would be a syntax error if $(cmd_$(1)) is empty. When CONFIG_TRIM_UNUSED_KSYMS is disabled, $(call cmd,gen_ksymdeps) in scripts/Makefile.build would be expanded into: set -e; { ; } >/dev/null ..., which causes an syntax error. I also tried this: cmd = @set -e; $(echo-cmd) ( $(cmd_$(1)) ) >/dev/null ... but this causes a syntax error for the same reason. So, finally I adopted: cmd = @set -e; $(echo-cmd) exec >/dev/null; $(cmd_$(1)) [1]: https://lore.kernel.org/lkml/20210514135752.2910387-1-arnd@kernel.org/ Signed-off-by: Masahiro Yamada Signed-off-by: Sasha Levin --- scripts/Kbuild.include | 7 ++++++- 1 file changed, 6 insertions(+), 1 deletion(-) diff --git a/scripts/Kbuild.include b/scripts/Kbuild.include index 7da10afc92c6..b14a7d4a2f05 100644 --- a/scripts/Kbuild.include +++ b/scripts/Kbuild.include @@ -182,8 +182,13 @@ clean := -f $(srctree)/scripts/Makefile.clean obj echo-cmd = $(if $($(quiet)cmd_$(1)),\ echo ' $(call escsq,$($(quiet)cmd_$(1)))$(echo-why)';) +# sink stdout for 'make -s' + redirect := + quiet_redirect := +silent_redirect := exec >/dev/null; + # printing commands -cmd = @set -e; $(echo-cmd) $(cmd_$(1)) +cmd = @set -e; $(echo-cmd) $($(quiet)redirect) $(cmd_$(1)) ### # if_changed - execute command if any prerequisite is newer than From 3446233096ff32e7b14ff3a25e4a13bb31554f1e Mon Sep 17 00:00:00 2001 From: Grygorii Strashko Date: Sat, 22 May 2021 01:24:09 +0300 Subject: [PATCH 22/72] ARM: dts: am57xx-cl-som-am57x: fix ti,no-reset-on-init flag for gpios [ Upstream commit b644c5e01c870056e13a096e14b9a92075c8f682 ] The ti,no-reset-on-init flag need to be at the interconnect target module level for the modules that have it defined.

The PHY needs an exact 100MHz reference clock to function if the PCIe refclock is not fed in via the refclock pads. While this mode is not supported (yet) in the driver it doesn't hurt to make sure we are providing a clock with the right rate. The AUX clock is specified to have a maximum clock rate of 10MHz. So the current setup, which drives it straight from the 25MHz oscillator is actually overclocking the AUX input.

Though, if KBUILD_BUILD_TIMESTAMP is set, an explicit timestamp for the build was requested, in which case we should not ignore it. If a user follows the documentation for reproducible builds [1] and defines KBUILD_BUILD_TIMESTAMP as the git commit timestamp, a clean build will have the correct timestamp. A subsequent cherry-pick (or amend) changes the commit timestamp and if an incremental build is done with a different KBUILD_BUILD_TIMESTAMP now, that new value is not taken into consideration. But it should for reproducibility. Hence, whenever KBUILD_BUILD_TIMESTAMP is explicitly set, do not ignore UTS_VERSION when making a decision about whether the regenerated version of compile.h should be moved into place.

Therefore driver should not enforce specific trigger type - edge falling - but instead rely on Devicetree to configure it. The Maxim 77686 datasheet describes the interrupt line as active low with a requirement of acknowledge from the CPU therefore the edge falling is not correct. The interrupt line is shared between PMIC and RTC driver, so using level sensitive interrupt is here especially important to avoid races. With an edge configuration in case if first PMIC signals interrupt followed shortly after by the RTC, the interrupt might not be yet cleared/acked thus the second one would not be noticed.

Casting the type to an unsigned 64-bit value will cause integer underflow, making the runtime_refresh_within return false instead of true. These situations are rare, but they do happen. This does not cause user-facing issues or errors; other than possibly unthrottling cfs_rq's using runtime from the previous period(s), making the CFS bandwidth enforcement less strict in those (special) situations.

That is: missing or too many arguments do not cause any compile error or warning. The same is true if the return type of the called function changes. This can lead to quite random bugs. - Sign and zero extension of arguments is missing. Given that the s390 C ABI requires that the caller of a function performs proper sign and zero extension this can also lead to subtle bugs. - If arguments to the CALL_ON_STACK() macros contain functions calls register corruption can happen due to register asm constructs being used. Therefore introduce a new call_on_stack() macro which is supposed to fix all these problems.

The Turris MOX rWTM firmware can be used on any Armada 37xx device, giving them access to the rWTM hardware random number generator, which is otherwise unavailable. This change allows Linux to load the turris-mox-rwtm.ko module on these boards. Tested on ESPRESSObin v5 with both default Marvell WTMI firmware and CZ.NIC's firmware. With default WTMI firmware the turris-mox-rwtm fails to probe, while with CZ.NIC's firmware it registers the HW random number generator.

The scenario in detail: 1) Thread 1 uses kmem_cache_destroy() to destroy kmem_cache A which is mergeable, it decreases A's refcount and if refcount is 0, then call memcg_set_kmem_cache_dying() which set A->memcg_params.dying = true, then unlock the slab_mutex and call flush_memcg_workqueue(), it may cost a while. Note: now the sysfs node(like '/kernel/slab/:0000248') of A is still present, it will be deleted in shutdown_cache() which will be called after flush_memcg_workqueue() is done and lock the slab_mutex again. 2) Now if thread 2 is coming, it use kmem_cache_create() to create B, which is mergeable with A(their size is same), it gain the lock of slab_mutex, then call __kmem_cache_alias() trying to find a mergeable node, because of the below added code in commit d38a2b7a9c93 ("mm: memcg/slab: fix memory leak at non-root kmem_cache destroy"), B is not mergeable with A whose memcg_params.dying is true. int slab_unmergeable(struct kmem_cache *s) if (s->refcount < 0) return 1; /* * Skip the dying kmem_cache. */ if (s->memcg_params.dying) return 1; return 0; } So B has to create its own sysfs node by calling: create_cache-> __kmem_cache_create-> sysfs_slab_add-> kobject_init_and_add Because B is mergeable itself, its filename of sysfs node is based on its size, like '/kernel/slab/:0000248', which is duplicate with A, and the sysfs node of A is still present now, so kobject_init_and_add() will return fail and result in kmem_cache_create() fail. Concurrently modprobe and rmmod the two modules below can reproduce the issue quickly: nf_conntrack_expect, se_sess_cache. See call trace in the end. LTS versions of v4.19.y and v5.4.y have this problem, whereas linux versions after v5.9 do not have this problem because the patchset: ("The new cgroup slab memory controller") almost refactored memcg slab. A potential solution(this patch belongs): Just let the dying kmem_cache be mergeable, the slab_mutex lock can prevent the race between alias kmem_cache creating thread and root kmem_cache destroying thread. In the destroying thread, after flush_memcg_workqueue() is done, judge the refcount again, if someone reference it again during un-lock time, we don't need to destroy the kmem_cache completely, we can reuse it. Another potential solution: revert the commit d38a2b7a9c93 ("mm: memcg/slab: fix memory leak at non-root kmem_cache destroy"), compare to the fail of kmem_cache_create, the memory leak in special scenario seems less harmful.

Since commit 2796d0c648c9 ("bridge: Automatically manage port promiscuous mode.") bridges with `vlan_filtering 1` and only 1 auto-port don't set IFF_PROMISC for unicast-filtering-capable ports. Normally on port changes `br_manage_promisc` is called to update the promisc flags and unicast filters if necessary, but it cannot distinguish between *new* ports and ones losing their promisc flag, and new ports end up not receiving the MAC address list. Fix this by calling `br_fdb_sync_static` in `br_add_if` after the port promisc flags are updated and the unicast filter was supposed to have been filled.

Commit 28e104d00281 ("net: ip_tunnel: fix mtu calculation") removed dev->hard_header_len subtraction when calculate MTU for tunnel devices as there is an overhead for device that has header_ops. But there are ETHER tunnel devices, like gre_tap or erspan, which don't have header_ops but set dev->hard_header_len during setup. This makes pkts greater than (MTU - ETH_HLEN) could not be xmited. Fix it by subtracting the ETHER tunnel devices' dev->hard_header_len for MTU calculation.

While TCP stack scales reasonably well, there is still one part that can be used to DDOS it. IPv6 Packet too big messages have to lookup/insert a new route, and if abused by attackers, can easily put hosts under high stress, with many cpus contending on a spinlock while one is stuck in fib6_run_gc() ip6_protocol_deliver_rcu() icmpv6_rcv() icmpv6_notify() tcp_v6_err() tcp_v6_mtu_reduced() inet6_csk_update_pmtu() ip6_rt_update_pmtu() __ip6_rt_update_pmtu() ip6_rt_cache_alloc() ip6_dst_alloc() dst_alloc() ip6_dst_gc() fib6_run_gc() spin_lock_bh() ... Some of our servers have been hit by malicious ICMPv6 packets trying to _increase_ the MTU/MSS of TCP flows. We believe these ICMPv6 packets are a result of a bug in one ISP stack, since they were blindly sent back for _every_ (small) packet sent to them. These packets are for one TCP flow: 09:24:36.266491 IP6 Addr1 > Victim ICMP6, packet too big, mtu 1460, length 1240 09:24:36.266509 IP6 Addr1 > Victim ICMP6, packet too big, mtu 1460, length 1240 09:24:36.316688 IP6 Addr1 > Victim ICMP6, packet too big, mtu 1460, length 1240 09:24:36.316704 IP6 Addr1 > Victim ICMP6, packet too big, mtu 1460, length 1240 09:24:36.608151 IP6 Addr1 > Victim ICMP6, packet too big, mtu 1460, length 1240 TCP stack can filter some silly requests : 1) MTU below IPV6_MIN_MTU can be filtered early in tcp_v6_err() 2) tcp_v6_mtu_reduced() can drop requests trying to increase current MSS. This tests happen before the IPv6 routing stack is entered, thus removing the potential contention and route exhaustion. Note that IPv6 stack was performing these checks, but too late (ie : after the route has been added, and after the potential garbage collect war) v2: fix typo caught by Martin, thanks ! v3: exports tcp_mtu_to_mss(), caught by David, thanks !
