+Subject: ALSA: hda: ignore invalid NHLT table
+
+From: Mark Pearson <markpearson@lenovo.com>
+
+[ Upstream commit a14a6219996ee6f6e858d83b11affc7907633687 ]
+
+On some Lenovo systems if the microphone is disabled in the BIOS
+only the NHLT table header is created, with no data. This means
+the endpoints field is not correctly set to zero - leading to an
+unintialised variable and hence invalid descriptors are parsed
+leading to page faults.
+
+The Lenovo firmware team is addressing this, but adding a check
+preventing invalid tables being parsed is worthwhile.
+
+Tested on a Lenovo T14.

+Subject: atm: eni: dont release is never initialized
+
+From: Tong Zhang <ztong0001@gmail.com>
+
+[ Upstream commit 4deb550bc3b698a1f03d0332cde3df154d1b6c1e ]
+
+label err_eni_release is reachable when eni_start() fail.
+In eni_start() it calls dev->phy->start() in the last step, if start()
+fail we don't need to call phy->stop(), if start() is never called, we
+neither need to call phy->stop(), otherwise null-ptr-deref will happen.
+
+In order to fix this issue, don't call phy->stop() in label err_eni_release

+Subject: atm: idt77252: fix null-ptr-dereference
+
+From: Tong Zhang <ztong0001@gmail.com>
+
+[ Upstream commit 4416e98594dc04590ebc498fc4e530009535c511 ]
+
+this one is similar to the phy_data allocation fix in uPD98402, the
+driver allocate the idt77105_priv and store to dev_data but later
+dereference using dev->dev_data, which will cause null-ptr-dereference.
+
+fix this issue by changing dev_data to phy_data so that PRIV(dev) can
+work correctly.

+From: Tong Zhang <ztong0001@gmail.com>
+
+[ Upstream commit a2bd45834e83d6c5a04d397bde13d744a4812dfc ]
+
+lanai_dev_open() can fail. When it fail, lanai->base is unmapped and the
+pci device is disabled. The caller, lanai_init_one(), then tries to run
+atm_dev_deregister(). This will subsequently call lanai_dev_close() and
+use the already released MMIO area.
+
+To fix this issue, set the lanai->base to NULL if open fail,
+and test the flag in lanai_dev_close().

+
+From: Tong Zhang <ztong0001@gmail.com>
+
+[ Upstream commit 3153724fc084d8ef640c611f269ddfb576d1dcb1 ]
+
+dev->dev_data is set in zatm.c, calling zatm_start() will overwrite this
+dev->dev_data in uPD98402_start() and a subsequent PRIV(dev)->lock
+(i.e dev->phy_data->lock) will result in a null-ptr-dereference.
+
+I believe this is a typo and what it actually want to do is to allocate
+phy_data instead of dev_data.

+
+From: Xunlei Pang <xlpang@linux.alibaba.com>
+
+[ Upstream commit 4f44657d74873735e93a50eb25014721a66aac19 ]
+
+The current blkio.throttle.io_service_bytes_recursive doesn't
+work correctly.
+
+As an example, for the following blkcg hierarchy:
+ (Made 1GB READ in test1, 512MB READ in test2)
+ test
+ / \
+ test1 test2
+
+$ head -n 1 test/test1/blkio.throttle.io_service_bytes_recursive
+8:0 Read 1073684480
+$ head -n 1 test/test2/blkio.throttle.io_service_bytes_recursive
+8:0 Read 537448448
+$ head -n 1 test/blkio.throttle.io_service_bytes_recursive
+8:0 Read 537448448
+
+Clearly, above data of "test" reflects "test2" not "test1"+"test2".
+
+Do the correct summary in blkg_rwstat_recursive_sum().

+register_disk() suppress uevents for devices with the GENHD_FL_HIDDEN
+but enables uevents at the end again in order to announce disk after

+
+When the device is removed the uevents are still on and user land sees

+
+When doing a large read or write workload we only

+which can cause problems with parallelizing large i/o
+(I/O ramps up more slowly than it should for large
+read/write workloads) especially with multichannel
+when the number of credits on the secondary channels
+starts out low (e.g. less than about 130) or when
+recovering after server throttled back the number
+of credit.

+Subject: gfs2: fix use-after-free in trans_drain
+
+From: Bob Peterson <rpeterso@redhat.com>
+
+[ Upstream commit 1a5a2cfd34c17db73c53ef127272c8c1ae220485 ]
+
+This patch adds code to function trans_drain to remove drained
+bd elements from the ail lists, if queued, before freeing the bd.
+If we don't remove the bd from the ail, function ail_drain will
+try to reference the bd after it has been freed by trans_drain.
+
+Thanks to Andy Price for his analysis of the problem.

+Subject: gianfar: fix jumbo packets+napi+rx overrun crash
+
+From: Michael Braun <michael-dev@fami-braun.de>
+
+[ Upstream commit d8861bab48b6c1fc3cdbcab8ff9d1eaea43afe7f ]
+
+When using jumbo packets and overrunning rx queue with napi enabled,
+the following sequence is observed in gfar_add_rx_frag:
+
+ | lstatus | | skb |
+t | lstatus, size, flags | first | len, data_len, *ptr |
+---+--------------------------------------+-------+-----------------------+
+13 | 18002348, 9032, INTERRUPT LAST | 0 | 9600, 8000, f554c12e |
+12 | 10000640, 1600, INTERRUPT | 0 | 8000, 6400, f554c12e |
+11 | 10000640, 1600, INTERRUPT | 0 | 6400, 4800, f554c12e |
+10 | 10000640, 1600, INTERRUPT | 0 | 4800, 3200, f554c12e |
+09 | 10000640, 1600, INTERRUPT | 0 | 3200, 1600, f554c12e |
+08 | 14000640, 1600, INTERRUPT FIRST | 0 | 1600, 0, f554c12e |
+07 | 14000640, 1600, INTERRUPT FIRST | 1 | 0, 0, f554c12e |
+06 | 1c000080, 128, INTERRUPT LAST FIRST | 1 | 0, 0, abf3bd6e |
+05 | 18002348, 9032, INTERRUPT LAST | 0 | 8000, 6400, c5a57780 |
+04 | 10000640, 1600, INTERRUPT | 0 | 6400, 4800, c5a57780 |
+03 | 10000640, 1600, INTERRUPT | 0 | 4800, 3200, c5a57780 |
+02 | 10000640, 1600, INTERRUPT | 0 | 3200, 1600, c5a57780 |
+01 | 10000640, 1600, INTERRUPT | 0 | 1600, 0, c5a57780 |
+00 | 14000640, 1600, INTERRUPT FIRST | 1 | 0, 0, c5a57780 |
+
+So at t=7 a new packets is started but not finished, probably due to rx
+overrun - but rx overrun is not indicated in the flags. Instead a new
+packets starts at t=8. This results in skb->len to exceed size for the LAST
+fragment at t=13 and thus a negative fragment size added to the skb.
+
+This then crashes:
+
+kernel BUG at include/linux/skbuff.h:2277!
+Oops: Exception in kernel mode, sig: 5 [#1]

+
+This patch fixes this by checking for computed LAST fragment size, so a
+negative sized fragment is never added.
+In order to prevent the newer rx frame from getting corrupted, the FIRST
+flag is checked to discard the incomplete older frame.

+Subject: ia64: fix ia64_syscall_get_set_arguments() for break-based syscalls
+
+From: Sergei Trofimovich <slyfox@gentoo.org>
+
+[ Upstream commit 0ceb1ace4a2778e34a5414e5349712ae4dc41d85 ]
+
+In https://bugs.gentoo.org/769614 Dmitry noticed that
+`ptrace(PTRACE_GET_SYSCALL_INFO)` does not work for syscalls called via
+glibc's syscall() wrapper.
+
+ia64 has two ways to call syscalls from userspace: via `break` and via
+`eps` instructions.
+
+The difference is in stack layout:
+
+1. `eps` creates simple stack frame: no locals, in{0..7} == out{0..8}
+2. `break` uses userspace stack frame: may be locals (glibc provides
+ one), in{0..7} == out{0..8}.
+
+Both work fine in syscall handling cde itself.
+
+But `ptrace(PTRACE_GET_SYSCALL_INFO)` uses unwind mechanism to
+re-extract syscall arguments but it does not account for locals.
+
+The change always skips locals registers. It should not change `eps`
+path as kernel's handler already enforces locals=0 and fixes `break`.
+
+Tested on v5.10 on rx3600 machine (ia64 9040 CPU).

+Subject: mm/fork: clear PASID for new mm
+
+From: Fenghua Yu <fenghua.yu@intel.com>
+
+[ Upstream commit 82e69a121be4b1597ce758534816a8ee04c8b761 ]
+
+When a new mm is created, its PASID should be cleared, i.e. the PASID is
+initialized to its init state 0 on both ARM and X86.
+
+This patch was part of the series introducing mm->pasid, but got lost
+along the way [1]. It still makes sense to have it, because each address
+space has a different PASID. And the IOMMU code in
+iommu_sva_alloc_pasid() expects the pasid field of a new mm struct to be
+cleared.

+Subject: mt76: fix tx skb error handling in mt76_dma_tx_queue_skb
+
+From: Felix Fietkau <nbd@nbd.name>
+
+[ Upstream commit ae064fc0e32a4d28389086d9f4b260a0c157cfee ]
+
+When running out of room in the tx queue after calling drv->tx_prepare_skb,
+the buffer list will already have been modified on MT7615 and newer drivers.
+This can leak a DMA mapping and will show up as swiotlb allocation failures
+on x86.
+
+Fix this by moving the queue length check further up. This is less accurate,
+since it can overestimate the needed room in the queue on MT7615 and newer,
+but the difference is small enough to not matter in practice.

+When accessing the timecounter register on an i.MX8MQ the kernel hangs.
+This is only the case when the interface is down. This can be reproduced
+by reading with 'phc_ctrl eth0 get'.
+
+Like described in the change in 91c0d987a9788dcc5fe26baafd73bf9242b68900
+the igp clock is disabled when the interface is down and leads to a
+system hang.
+
+So we check if the ptp clock status before reading the timecounter
+register.

+Subject: net: stmmac: fix dma physical address of descriptor when display ring
+
+From: Joakim Zhang <qiangqing.zhang@nxp.com>
+
+[ Upstream commit bfaf91ca848e758ed7be99b61fd936d03819fa56 ]
+
+Driver uses dma_alloc_coherent to allocate dma memory for descriptors,
+dma_alloc_coherent will return both the virtual address and physical
+address. AFAIK, virt_to_phys could not convert virtual address to
+physical address, for which memory is allocated by dma_alloc_coherent.
+
+dwmac4_display_ring() function is broken for various descriptor, it only
+support normal descriptor(struct dma_desc) now, this patch also extends to
+support all descriptor types.

+
+[ Upstream commit 62765d39553cfd1ad340124fe1e280450e8c89e2 ]
+
+When priv->rx_skbuff or priv->tx_skbuff is NULL, no error return code of
+uhdlc_init() is assigned.
+To fix this bug, ret is assigned with -ENOMEM in these cases.

+
+From: Frank Sorenson <sorenson@redhat.com>
+
+[ Upstream commit ad3dbe35c833c2d4d0bbf3f04c785d32f931e7c9 ]
+
+CREATE requests return a post_op_fh3, rather than nfs_fh3. The
+post_op_fh3 includes an extra word to indicate 'handle_follows'.
+
+Without that additional word, create fails when full 64-byte
+filehandles are in use.
+
+Add NFS3_post_op_fh_sz, and correct the size calculation for
+NFS3_createres_sz.

+
+[ Upstream commit 4f8be1f53bf615102d103c0509ffa9596f65b718 ]
+
+The NFSv4 protocol doesn't have any notion of reomoving an attribute, so
+removexattr(path,"system.nfs4_acl") doesn't make sense.
+
+There's no documented return value. Arguably it could be EOPNOTSUPP but
+I'm a little worried an application might take that to mean that we
+don't support ACLs or xattrs. How about EINVAL?

+Subject: nvme: simplify error logic in nvme_validate_ns()
+
+From: Hannes Reinecke <hare@suse.de>
+
+[ Upstream commit d95c1f4179a7f3ea8aa728ed00252a8ed0f8158f ]
+
+We only should remove namespaces when we get fatal error back from
+the device or when the namespace IDs have changed.
+So instead of painfully masking out error numbers which might indicate
+that the error should be ignored we could use an NVME status code
+to indicated when the namespace should be removed.
+That simplifies the final logic and makes it less error-prone.

+Subject: powerpc/4xx: Fix build errors from mfdcr()
+
+From: Michael Ellerman <mpe@ellerman.id.au>
+
+[ Upstream commit eead089311f4d935ab5d1d8fbb0c42ad44699ada ]
+
+lkp reported a build error in fsp2.o:
+
+ CC arch/powerpc/platforms/44x/fsp2.o
+ {standard input}:577: Error: unsupported relocation against base
+
+Which comes from:
+
+ pr_err("GESR0: 0x%08x\n", mfdcr(base + PLB4OPB_GESR0));
+
+Where our mfdcr() macro is stringifying "base + PLB4OPB_GESR0", and
+passing that to the assembler, which obviously doesn't work.
+
+The mfdcr() macro already checks that the argument is constant using
+__builtin_constant_p(), and if not calls the out-of-line version of
+mfdcr(). But in this case GCC is smart enough to notice that "base +
+PLB4OPB_GESR0" will be constant, even though it's not something we can
+immediately stringify into a register number.
+
+Segher pointed out that passing the register number to the inline asm
+as a constant would be better, and in fact it fixes the build error,
+presumably because it gives GCC a chance to resolve the value.
+
+While we're at it, change mtdcr() similarly.

+Subject: Revert "r8152: adjust the settings about MAC clock speed down for
+ RTL8153"
+
+From: Hayes Wang <hayeswang@realtek.com>
+
+[ Upstream commit 4b5dc1a94d4f92b5845e98bd9ae344b26d933aad ]
+
+This reverts commit 134f98bcf1b898fb9d6f2b91bc85dd2e5478b4b8.
+
+The r8153_mac_clk_spd() is used for RTL8153A only, because the register
+table of RTL8153B is different from RTL8153A. However, this function would
+be called when RTL8153B calls r8153_first_init() and r8153_enter_oob().
+That causes RTL8153B becomes unstable when suspending and resuming. The
+worst case may let the device stop working.
+
+Besides, revert this commit to disable MAC clock speed down for RTL8153A.
+It would avoid the known issue when enabling U1. The data of the first
+control transfer may be wrong when exiting U1.

+Subject: sparc64: Fix opcode filtering in handling of no fault loads
+
+From: Rob Gardner <rob.gardner@oracle.com>
+
+[ Upstream commit e5e8b80d352ec999d2bba3ea584f541c83f4ca3f ]
+
+is_no_fault_exception() has two bugs which were discovered via random
+opcode testing with stress-ng. Both are caused by improper filtering
+of opcodes.
+
+The first bug can be triggered by a floating point store with a no-fault
+ASI, for instance "sta %f0, [%g0] #ASI_PNF", opcode C1A01040.
+
+The code first tests op3[5] (0x1000000), which denotes a floating
+point instruction, and then tests op3[2] (0x200000), which denotes a
+store instruction. But these bits are not mutually exclusive, and the
+above mentioned opcode has both bits set. The intent is to filter out
+stores, so the test for stores must be done first in order to have
+any effect.
+
+The second bug can be triggered by a floating point load with one of
+the invalid ASI values 0x8e or 0x8f, which pass this check in
+is_no_fault_exception():
+ if ((asi & 0xf2) == ASI_PNF)
+
+An example instruction is "ldqa [%l7 + %o7] #ASI 0x8f, %f38",
+opcode CF95D1EF. Asi values greater than 0x8b (ASI_SNFL) are fatal
+in handle_ldf_stq(), and is_no_fault_exception() must not allow these
+invalid asi values to make it that far.
+
+In both of these cases, handle_ldf_stq() reacts by calling
+sun4v_data_access_exception() or spitfire_data_access_exception(),
+which call is_no_fault_exception() and results in an infinite
+recursion.

+Subject: staging: rtl8192e: fix kconfig dependency on CRYPTO
+
+From: Julian Braha <julianbraha@gmail.com>
+
+[ Upstream commit 7c36194558cf49a86a53b5f60db8046c5e3013ae ]
+
+When RTLLIB_CRYPTO_TKIP is enabled and CRYPTO is disabled,
+Kbuild gives the following warning:
+
+WARNING: unmet direct dependencies detected for CRYPTO_MICHAEL_MIC
+ Depends on [n]: CRYPTO [=n]
+ Selected by [m]:
+ - RTLLIB_CRYPTO_TKIP [=m] && STAGING [=y] && RTLLIB [=m]
+
+WARNING: unmet direct dependencies detected for CRYPTO_LIB_ARC4
+ Depends on [n]: CRYPTO [=n]
+ Selected by [m]:
+ - RTLLIB_CRYPTO_TKIP [=m] && STAGING [=y] && RTLLIB [=m]
+ - RTLLIB_CRYPTO_WEP [=m] && STAGING [=y] && RTLLIB [=m]
+
+This is because RTLLIB_CRYPTO_TKIP selects CRYPTO_MICHAEL_MIC and
+CRYPTO_LIB_ARC4, without depending on or selecting CRYPTO,
+despite those config options being subordinate to CRYPTO.

+Subject: u64_stats,lockdep: Fix u64_stats_init() vs lockdep
+
+From: Peter Zijlstra <peterz@infradead.org>
+
+[ Upstream commit d5b0e0677bfd5efd17c5bbb00156931f0d41cb85 ]
+
+Jakub reported that:
+
+ static struct net_device *rtl8139_init_board(struct pci_dev *pdev)
+ {
+ ...
+ u64_stats_init(&tp->rx_stats.syncp);
+ u64_stats_init(&tp->tx_stats.syncp);
+ ...
+ }
+
+results in lockdep getting confused between the RX and TX stats lock.
+This is because u64_stats_init() is an inline calling seqcount_init(),
+which is a macro using a static variable to generate a lockdep class.
+
+By wrapping that in an inline, we negate the effect of the macro and
+fold the static key variable, hence the confusion.
+
+Fix by also making u64_stats_init() a macro for the case where it
+matters, leaving the other case an inline for argument validation
+etc.
