[ Upstream commit 106d45f350c7cac876844dc685845cba4ffdb70b ]
When tracing instances where we open and close WKA ports, we also pass the
request-ID of the respective FSF command.
But after successfully sending the FSF command we must not use the
request-object anymore, as this might result in an use-after-free (see
"zfcp: fix request object use-after-free in send path causing seqno
errors" ).
To fix this add a new variable that caches the request-ID before sending
the request. This won't change during the hand-off to the FCP channel,
and so it's safe to trace this cached request-ID later, instead of using
the request object.

[ Upstream commit fe22cd9b7c980b8b948ec85f034a8668c57ec867 ]
Currently, pr_debug and pr_devel will not elide function call arguments
appearing in calls to the no_printk for these macros. This is because
all side effects must be honored before proceeding to the 0-value
assignment in no_printk.
The behavior is contrary to documentation found in the CodingStyle and
the header file where these functions are declared.
This patch corrects that behavior by shunting out the call to no_printk
completely. The format string is still checked by gcc for correctness,
but no code seems to be emitted in common cases.

commit 3976626ea3d2011f8fd3f3a47070a8b792018253 upstream.
Commit 62e3a3e342af changed get_pages() to initialise
msm_gem_object::pages before trying to initialise msm_gem_object::sgt,
so that put_pages() would properly clean up pages in the failure
case.
However, this means that put_pages() now needs to check that
msm_gem_object::sgt is not null before trying to clean it up, and
this check was only applied to part of the cleanup code. Move
it all into the conditional block. (Strictly speaking we don't
need to make the kfree() conditional, but since we can't avoid
checking for null ourselves we may as well do so.)

commit c7858bf16c0b2cc62f475f31e6df28c3a68da1d6 upstream.
The asm-prototypes.h file is used to provide dummy function declarations
for genksyms, when processing asm files with EXPORT_SYMBOL. Make sure
that any architecture defines get out of our way. x86 currently has an
issue with memcpy on 64bit with CONFIG_KMEMCHECK=y and with
memset/__memset on 32bit:
$ cat init/test.c
#include <asm/asm-prototypes.h>
$ make -s init/test.o

...
During real build, this manifests itself by genksyms segfaulting.

commit 6ade20327dbb808882888ed8ccded71e93067cf9 upstream.
find_vmap_area() can return a NULL pointer and we're going to
dereference it without checking it first. Use the existing
find_vm_area() function which does exactly what we want and checks for
the NULL pointer.

This fix addresses https://bugzilla.kernel.org/show_bug.cgi?id=201071
Commit 5025f7f7d506 wrongly relied on __dev_change_flags to notify users of
dev flag changes in the case when dev->rtnl_link_state = RTNL_LINK_INITIALIZED.
Fix it by indicating flag changes explicitly to __dev_notify_flags.

commit a33a5d2d16cb84bea8d5f5510f3a41aa48b5c467 upstream.
The generic pending interrupt mechanism moves interrupts from the interrupt
handler on the original target CPU to the new destination CPU. This is
required for x86 and ia64 due to the way the interrupt delivery and
acknowledge works if the interrupts are not remapped.
However that update can fail for various reasons. Some of them are valid
reasons to discard the pending update, but the case, when the previous move
has not been fully cleaned up is not a legit reason to fail.
Check the return value of irq_do_set_affinity() for -EBUSY, which indicates
a pending cleanup, and rearm the pending move in the irq dexcriptor so it's
tried again when the next interrupt arrives.

commit 7118fd9bd975a9f3093239d4c0f4e15356b57fab upstream.
pan_display_atomic() calls drm_atomic_clean_old_fb() to sanitize the
legacy FB fields (plane->fb and plane->old_fb). However it was building
the plane mask to pass to this function incorrectly (the bitwise OR was
using plane indices rather than plane masks). The end result was that
sometimes the legacy pointers would become out of sync with the atomic
pointers. If another operation tried to re-set the same FB onto the
plane, we might end up with the pointers back in sync, but improper
reference counts, which would eventually lead to system crashes when we
accessed a pointer to a prematurely-destroyed FB.
The cause here was a very subtle bug introduced in commit:
commit 07d3bad6c1210bd21e85d084807ef4ee4ac43a78

drm/core: Fix old_fb handling in pan_display_atomic.
I found the crashes were most easily reproduced (on i915 at least) by
starting X and then VT switching to a VT that wasn't running a console
instance...the sequence of vt/fbcon entries that happen in that case
trigger a reference count mismatch and crash the system.

commit 6988f31d558aa8c744464a7f6d91d34ada48ad12 upstream.
Replace superfluous VM_BUG_ON() with comment about correct usage.
Technically reverts commit 1d148e218a0d ("mm: add VM_BUG_ON_PAGE() to
page_mapcount()"), but context lines have changed.
Function isolate_migratepages_block() runs some checks out of lru_lock
when choose pages for migration. After checking PageLRU() it checks
extra page references by comparing page_count() and page_mapcount().
Between these two checks page could be removed from lru, freed and taken
by slab.
As a result this race triggers VM_BUG_ON(PageSlab()) in page_mapcount().
Race window is tiny. For certain workload this happens around once a
year.

commit a068aab42258e25094bc2c159948d263ed7d7a77 upstream.
kobject_init_and_add() takes reference even when it fails.
If this function returns an error, kobject_put() must be called to
properly clean up the memory associated with the object. Previous
commit "b8eb718348b8" fixed a similar problem.

In function qlcnic_83xx_interrupt_test(), function
qlcnic_83xx_diag_alloc_res() is not handled by function
qlcnic_83xx_diag_free_res() after a call of the function
qlcnic_alloc_mbx_args() failed. Fix this issue by adding
a jump target "fail_mbx_args", and jump to this new target
when qlcnic_alloc_mbx_args() failed.

commit 976eba8ab596bab94b9714cd46d38d5c6a2c660d upstream.
In Commit dd9ee3444014 ("vti4: Fix a ipip packet processing bug in
'IPCOMP' virtual tunnel"), it tries to receive IPIP packets in vti
by calling xfrm_input(). This case happens when a small packet or
frag sent by peer is too small to get compressed.
However, xfrm_input() will still get to the IPCOMP path where skb
sec_path is set, but never dropped while it should have been done
in vti_ipcomp4_protocol.cb_handler(vti_rcv_cb), as it's not an
ipcomp4 packet. This will cause that the packet can never pass
xfrm4_policy_check() in the upper protocol rcv functions.
So this patch is to call ip_tunnel_rcv() to process IPIP packets
instead.

commit f981c57ffd2d7cf2dd4b6d6f8fcb3965df42f54c upstream.
The ipip tunnel introduced in commit dd9ee3444014 ("vti4: Fix a ipip
packet processing bug in 'IPCOMP' virtual tunnel") largely duplicated
the existing vti_input and vti_recv functions. Refactored to
deduplicate the common code.

commit f6a23d85d078c2ffde79c66ca81d0a1dde451649 upstream.
This patch is to fix a crash:
[ ] kasan: GPF could be caused by NULL-ptr deref or user memory access
[ ] general protection fault: 0000 [#1] SMP KASAN PTI
[ ] RIP: 0010:ipv6_local_error+0xac/0x7a0

This occurred when sending a v4 skb over vxlan6 over ipsec, in which case
skb->protocol == htons(ETH_P_IPV6) while skb->sk->sk_family == AF_INET in
xfrm_local_error(). Then it will go to xfrm6_local_error() where it tries
to get ipv6 info from a ipv4 sk.
This issue was actually fixed by Commit 628e341f319f ("xfrm: make local
error reporting more robust"), but brought back by Commit 844d48746e4b
("xfrm: choose protocol family by skb protocol").
So to fix it, we should call xfrm6_local_error() only when skb->protocol
is htons(ETH_P_IPV6) and skb->sk->sk_family is AF_INET6.

commit ed17b8d377eaf6b4a01d46942b4c647378a79bdd upstream.
This waring can be triggered simply by:

The issue was introduced by Commit 7cb8a93968e3 ("xfrm: Allow inserting
policies with matching mark and different priorities"). After that, the
policies [1] and [2] would be able to be added with different priorities.
However, policy [3] will actually match both [1] and [2]. Policy [1]
was matched due to the 1st 'return true' in xfrm_policy_mark_match(),
and policy [2] was matched due to the 2nd 'return true' in there. It
caused WARN_ON() in xfrm_policy_insert_list().
This patch is to fix it by only (the same value and priority) as the
same policy in xfrm_policy_mark_match().
Thanks to Yuehaibing, we could make this fix better.
v1->v2:
- check policy->mark.v == pol->mark.v only without mask.

commit afcaf61be9d1dbdee5ec186d1dcc67b6b692180f upstream.
For beet mode, when it's ipv6 inner address with nexthdrs set,
the packet format might be:
----------------------------------------------------
| outer | | dest | | | ESP | ESP |
| IP hdr | ESP | opts.| TCP | Data | Trailer | ICV |
----------------------------------------------------
The nexthdr from ESP could be NEXTHDR_HOP(0), so it should
continue processing the packet when nexthdr returns 0 in
xfrm_input(). Otherwise, when ipv6 nexthdr is set, the
packet will be dropped.
I don't see any error cases that nexthdr may return 0. So
fix it by removing the check for nexthdr == 0.

commit 88743470668ef5eb6b7ba9e0f99888e5999bf172 upstream.
The intermediate result of the old term (4UL * 1024 * 1024 * 1024) is
4 294 967 296 or 0x100000000 which is no problem on 64 bit systems.
The patch does not change the later overall result of 0x100000 for
MAX_DMA32_PFN (after it has been shifted by PAGE_SHIFT). The new
calculation yields the same result, but does not require 64 bit
arithmetic.
On 32 bit systems the old calculation suffers from an arithmetic
overflow in that intermediate term in braces: 4UL aka unsigned long int
is 4 byte wide and an arithmetic overflow happens (the 0x100000000 does
not fit in 4 bytes), the in braces result is truncated to zero, the
following right shift does not alter that, so MAX_DMA32_PFN evaluates to
0 on 32 bit systems.
That wrong value is a problem in a comparision against MAX_DMA32_PFN in
the init code for swiotlb in pci_swiotlb_detect_4gb() to decide if
swiotlb should be active. That comparison yields the opposite result,
when compiling on 32 bit systems.
This was not possible before
1b7e03ef7570 ("x86, NUMA: Enable emulation on 32bit too")
when that MAX_DMA32_PFN was first made visible to x86_32 (and which
landed in v3.0).
In practice this wasn't a problem, unless CONFIG_SWIOTLB is active on
x86-32.
However if one has set CONFIG_IOMMU_INTEL, since
c5a5dc4cbbf4 ("iommu/vt-d: Don't switch off swiotlb if bounce page is used")
there's a dependency on CONFIG_SWIOTLB, which was not necessarily
active before. That landed in v5.4, where we noticed it in the fli4l
Linux distribution. We have CONFIG_IOMMU_INTEL active on both 32 and 64
bit kernel configs there (I could not find out why, so let's just say
historical reasons).
The effect is at boot time 64 MiB (default size) were allocated for
bounce buffers now, which is a noticeable amount of memory on small
systems like pcengines ALIX 2D3 with 256 MiB memory, which are still
frequently used as home routers.
We noticed this effect when migrating from kernel v4.19 (LTS) to v5.4
(LTS) in fli4l and got that kernel messages for example:
Linux version 5.4.22 (buildroot@buildroot) (gcc version 7.3.0 (Buildroot 2018.02.8)) #1 SMP Mon Nov 26 23:40:00 CET 2018
…
Memory: 183484K/261756K available (4594K kernel code, 393K rwdata, 1660K rodata, 536K init, 456K bss , 78272K reserved, 0K cma-reserved, 0K highmem)
…
PCI-DMA: Using software bounce buffering for IO (SWIOTLB)
software IO TLB: mapped [mem 0x0bb78000-0x0fb78000] (64MB)
The initial analysis and the suggested fix was done by user 'sourcejedi'
at stackoverflow and explicitly marked as GPLv2 for inclusion in the
Linux kernel:
https://unix.stackexchange.com/a/520525/50007
The new calculation, which does not suffer from that overflow, is the
same as for arch/mips now as suggested by Robin Murphy.
The fix was tested by fli4l users on round about two dozen different
systems, including both 32 and 64 bit archs, bare metal and virtualized
machines.

[ Upstream commit a4ae32c71fe90794127b32d26d7ad795813b502e ]
An invariant of cap_bprm_set_creds is that every field in the new cred
structure that cap_bprm_set_creds might set, needs to be set every
time to ensure the fields does not get a stale value.
The field cap_ambient is not set every time cap_bprm_set_creds is
called, which means that if there is a suid or sgid script with an
interpreter that has neither the suid nor the sgid bits set the
interpreter should be able to accept ambient credentials.
Unfortuantely because cap_ambient is not reset to it's original value
the interpreter can not accept ambient credentials.
Given that the ambient capability set is expected to be controlled by
the caller, I don't think this is particularly serious. But it is
definitely worth fixing so the code works correctly.
I have tested to verify my reading of the code is correct and the
interpreter of a sgid can receive ambient capabilities with this
change and cannot receive ambient capabilities without this change.

[ Upstream commit 4020d1ccbe55bdf67b31d718d2400506eaf4b43f ]
The Asus USB DAC is a USB type-C audio dongle for connecting to
the headset and headphone. The volume minimum value -23040 which
is 0xa600 in hexadecimal with the resolution value 1 indicates
this should be endianness issue caused by the firmware bug. Add
a volume quirk to fix the volume control problem.
Also fixes this warning:
Warning! Unlikely big volume range (=23040), cval->res is probably wrong.
[5] FU [Headset Capture Volume] ch = 1, val = -23040/0/1

The "info.index" variable can be 31 in "1 << info.index".
This might trigger an undefined behavior since 1 is signed.
Fix this by casting 1 to 1u just to be sure "1u << 31" is defined.
