Since [1], added in 5.7, the absence of a gpio-ranges property has prevented GPIOs from being restored to inputs when released. Add those properties for BCM283x and BCM2711 devices.

Because of commit 9cb2ff11 ("spi: cadence-quadspi: Disable Auto-HW polling"), which does a write to the CQSPI_REG_WR_COMPLETION_CTRL register regardless of any condition. Well, the Cadence QuadSPI controller on Intel's SoCFPGA platforms does not implement the CQSPI_REG_WR_COMPLETION_CTRL register, thus a write to this register results in a crash! So starting with v5.16, I introduced the patch 98d948eb ("spi: cadence-quadspi: fix write completion support"), which adds the dts compatible "intel,socfpga-qspi" that is specific for versions that doesn't have the CQSPI_REG_WR_COMPLETION_CTRL register implemented.

DAMON debugfs interface iterates current monitoring targets in 'dbgfs_target_ids_read()' while holding the corresponding 'kdamond_lock'. However, it also destructs the monitoring targets in 'dbgfs_before_terminate()' without holding the lock. This can result in a use_after_free bug. This commit avoids the race by protecting the destruction with the corresponding 'kdamond_lock'. Link: https://lkml.kernel.org/r/20211221094447.2241-1-sj@kernel.org Reported-by:

It is not easily reproducible, but on 5.16-rc I have several times hit the VM_BUG_ON_PAGE(PageTail(page), page) in page_cache_add_speculative(): usually from filemap_get_read_batch() for an ext4 read, yesterday from next_uptodate_page() from filemap_map_pages() for a shmem fault. That BUG used to be placed where page_ref_add_unless() had succeeded, but now it is placed before folio_ref_add_unless() is attempted: that is not safe, since it is only the acquired reference which makes the page safe from racing THP collapse or split. We could keep the BUG, checking PageTail only when folio_ref_try_add_rcu() has succeeded; but I don't think it adds much value - just delete it.

When a memory error hits a tail page of a free hugepage, __page_handle_poison() is expected to be called to isolate the error in 4kB unit, but it's not called due to the outdated if-condition in memory_failure_hugetlb(). This loses the chance to isolate the error in the finer unit, so it's not optimal. Drop the condition. This "(p != head && TestSetPageHWPoison(head)" condition is based on the old semantics of PageHWPoison on hugepage (where PG_hwpoison flag was set on the subpage), so it's not necessray any more. By getting to set PG_hwpoison on head page for hugepages, concurrent error events on different subpages in a single hugepage can be prevented by TestSetPageHWPoison(head) at the beginning of memory_failure_hugetlb(). So dropping the condition should not reopen the race window originally mentioned in commit b985194c ("hwpoison, hugetlb: lock_page/unlock_page does not match for handling a free hugepage") [naoya.horiguchi@linux.dev: fix "HardwareCorrupted" counter] Link: https://lkml.kernel.org/r/20211220084851.GA1460264@u2004 Link: https://lkml.kernel.org/r/20211210110208.879740-1-naoya.horiguchi@linux.dev Signed-off-by:

When booting with crashkernel= on the kernel command line a warning similar to Kernel command line: ro console=ttyS0 crashkernel=256M Unknown kernel command line parameters "crashkernel=256M", will be passed to user space. is printed. This comes from crashkernel= being parsed independent from the kernel parameter handling mechanism. So the code in init/main.c doesn't know that crashkernel= is a valid kernel parameter and prints this incorrect warning. Suppress the warning by adding a dummy early_param handler for crashkernel=.

alloc_pages_vma() may try to allocate THP page on the local NUMA node first: page = __alloc_pages_node(hpage_node, gfp | __GFP_THISNODE | __GFP_NORETRY, order); And if the allocation fails it retries allowing remote memory: if (!page && (gfp & __GFP_DIRECT_RECLAIM)) page = __alloc_pages_node(hpage_node, gfp, order); However, this retry allocation completely ignores memory policy nodemask allowing allocation to escape restrictions. The first appearance of this bug seems to be the commit ac5b2c18 ("mm: thp: relax __GFP_THISNODE for MADV_HUGEPAGE mappings"). The bug disappeared later in the commit 89c83fb5 ("mm, thp: consolidate THP gfp handling into alloc_hugepage_direct_gfpmask") and reappeared again in slightly different form in the commit 76e654cc ("mm, page_alloc: allow hugepage fallback to remote nodes when madvised") Fix this by passing correct nodemask to the __alloc_pages() call.

There are some chances that the actual base of hardware is different from the value recorded by driver, so we have to reset the variable of ocp_base to sync it. Set ocp_base to -1. Then, it would be updated and the new base would be set to the hardware next time. Signed-off-by:

Commit 561d8352 ("bridge: use ndo_siocdevprivate") changed the source and destination arguments of copy_{to,from}_user in bridge's old_deviceless() from args[1] to uarg breaking SIOC{G,S}IFBR ioctls. Commit cbd7ad29 ("net: bridge: fix ioctl old_deviceless bridge argument") fixed only BRCTL_{ADD,DEL}_BRIDGES commands leaving BRCTL_GET_BRIDGES one untouched. The fixes BRCTL_GET_BRIDGES as well and has been tested with busybox's brctl. Example of broken brctl: $ brctl show bridge name bridge id STP enabled interfaces brctl: can't get bridge name for index 0: No such device or address Example of fixed brctl: $ brctl show bridge name bridge id STP enabled interfaces br0 8000.000000000000 no Fixes: 561d8352 ("bridge: use ndo_siocdevprivate") Signed-off-by:

For Ocelot switches, the CPU injected frames have an injection header where it can specify the QoS class of the packet and the DSA tag, now it uses the SKB priority to set that. If a traffic class to priority mapping is configured on the netdevice (with mqprio for example ...), it won't be considered for CPU injected headers. This patch make the QoS class aligned to the priority to traffic class mapping if it exists. Fixes: 8dce89aa ("net: dsa: ocelot: add tagger for Ocelot/Felix switches") Signed-off-by:

After commit d3256efd ("veth: allow enabling NAPI even without XDP"), if GRO is enabled on a veth device and TSO is disabled on the peer device, TCP skbs will go through the NAPI callback. If there is no XDP program attached, the veth code does not perform any share check, and shared/cloned skbs could enter the GRO engine. Ignat reported a BUG triggered later-on due to the above condition: [ 53.970529][ C1] kernel BUG at net/core/skbuff.c:3574!
