[PATCH 4.19 01/12] net: phy: bcm7xxx: Fixed indirect MMD operations

[Greg Kroah-Hartman]

From: Florian Fainelli <f.fainelli@gmail.com>

commit d88fd1b546ff19c8040cfaea76bf16aed1c5a0bb upstream.

When EEE support was added to the 28nm EPHY it was assumed that it would
be able to support the standard clause 45 over clause 22 register access
method. It turns out that the PHY does not support that, which is the
very reason for using the indirect shadow mode 2 bank 3 access method.

Implement {read,write}_mmd to allow the standard PHY library routines
pertaining to EEE querying and configuration to work correctly on these
PHYs. This forces us to implement a __phy_set_clr_bits() function that
does not grab the MDIO bus lock since the PHY driver's {read,write}_mmd
functions are always called with that lock held.

Fixes: 83ee102a6998 ("net: phy: bcm7xxx: add support for 28nm EPHY")
[florian: adjust locking since phy_{read,write}_mmd are called with no
PHYLIB locks held]

[PATCH 4.19 02/12] HID: apple: Fix logical maximum and usage maximum of Magic Keyboard JIS

Position 64(Logical Maximum) and 70(Usage Maximum) are 101.
Both should be 0xE7 to support JIS specific keys(ろ, Eisu, Kana, |) support.
position 117 is also 101 but not related(it is Usage 65h).

There are no difference of product id between JIS and ANSI.
They are same 0x0267.

[PATCH 4.19 03/12] netfilter: ip6_tables: zero-initialize fragment offset

[Greg Kroah-Hartman]

From: Jeremy Sowden <jeremy@azazel.net>

[ Upstream commit 310e2d43c3ad429c1fba4b175806cf1f55ed73a6 ]

ip6tables only sets the `IP6T_F_PROTO` flag on a rule if a protocol is
specified (`-p tcp`, for example).  However, if the flag is not set,
`ip6_packet_match` doesn't call `ipv6_find_hdr` for the skb, in which
case the fragment offset is left uninitialized and a garbage value is
passed to each matcher.

[PATCH 4.19 05/12] m68k: Handle arrivals of multiple signals correctly

[Greg Kroah-Hartman]

From: Al Viro <viro@zeniv.linux.org.uk>

[ Upstream commit 4bb0bd81ce5e97092dfda6a106d414b703ec0ee8 ]

When we have several pending signals, have entered with the kernel
with large exception frame *and* have already built at least one
sigframe, regs->stkadj is going to be non-zero and regs->format/sr/pc
are going to be junk - the real values are in shifted exception stack
frame we'd built when putting together the first sigframe.

If that happens, subsequent sigframes are going to be garbage.
Not hard to fix - just need to find the "adjusted" frame first
and look for format/vector/sr/pc in it.

[PATCH 4.19 06/12] net: prevent user from passing illegal stab size

[Greg Kroah-Hartman]

From: 王贇 <yun.wang@linux.alibaba.com>

[ Upstream commit b193e15ac69d56f35e1d8e2b5d16cbd47764d053 ]

We observed below report when playing with netlink sock:

  UBSAN: shift-out-of-bounds in net/sched/sch_api.c:580:10
  shift exponent 249 is too large for 32-bit type
  CPU: 0 PID: 685 Comm: a.out Not tainted
  Call Trace:
   dump_stack_lvl+0x8d/0xcf
   ubsan_epilogue+0xa/0x4e
   __ubsan_handle_shift_out_of_bounds+0x161/0x182
   __qdisc_calculate_pkt_len+0xf0/0x190
   __dev_queue_xmit+0x2ed/0x15b0

it seems like kernel won't check the stab log value passing from
user, and will use the insane value later to calculate pkt_len.

This patch just add a check on the size/cell_log to avoid insane
calculation.

[PATCH 4.19 07/12] mac80211: check return value of rhashtable_init

[Greg Kroah-Hartman]

From: MichelleJin <shjy180909@gmail.com>

[ Upstream commit 111461d573741c17eafad029ac93474fa9adcce0 ]

When rhashtable_init() fails, it returns -EINVAL.
However, since error return value of rhashtable_init is not checked,
it can cause use of uninitialized pointers.
So, fix unhandled errors of rhashtable_init.

[PATCH 4.19 11/12] perf/x86: Reset destroy callback on event init failure

[Greg Kroah-Hartman]

From: Anand K Mistry <amistry@google.com>

[ Upstream commit 02d029a41dc986e2d5a77ecca45803857b346829 ]

perf_init_event tries multiple init callbacks and does not reset the
event state between tries. When x86_pmu_event_init runs, it
unconditionally sets the destroy callback to hw_perf_event_destroy. On
the next init attempt after x86_pmu_event_init, in perf_try_init_event,
if the pmu's capabilities includes PERF_PMU_CAP_NO_EXCLUDE, the destroy
callback will be run. However, if the next init didn't set the destroy
callback, hw_perf_event_destroy will be run (since the callback wasn't
reset).

Looking at other pmu init functions, the common pattern is to only set
the destroy callback on a successful init. Resetting the callback on
failure tries to replicate that pattern.

This was discovered after commit f11dd0d80555 ("perf/x86/amd/ibs: Extend
PERF_PMU_CAP_NO_EXCLUDE to IBS Op") when the second (and only second)
run of the perf tool after a reboot results in 0 samples being
generated. The extra run of hw_perf_event_destroy results in
active_events having an extra decrement on each perf run. The second run
has active_events == 0 and every subsequent run has active_events < 0.
When active_events == 0, the NMI handler will early-out and not record
any samples.
