Orange Pi Zero Plus uses a Realtek RTL8211E RGMII Gigabit PHY, but its currently set to plain RGMII mode meaning that it doesn't introduce delays. With this setup, TX packets are completely lost and changing the mode to RGMII-ID so the PHY will add delays internally fixes the issue.

Function sunxi_rsb_hw_exit() is sometimes called with pm runtime disabled, so in such cases pm_runtime_resume() will fail with -EACCES. Instead of doing whole dance of enabling pm runtime and thus clock just to disable it again immediately, just check if disabling clock is needed. That way calling pm_runtime_resume() is not needed at all.

We've got a bug report about the non-working keyboard on ASUS ZenBook UX425UA. It seems that the PS/2 device isn't ready immediately at boot but takes some seconds to get ready. Until now, the only workaround is to defer the probe, but it's available only when the driver is a module. However, many distros, including openSUSE as in the original report, build the PS/2 input drivers into kernel, hence it won't work easily. This patch adds the support for the deferred probe for i8042 stuff as a workaround of the problem above. When the deferred probe mode is enabled and the device couldn't be probed, it'll be repeated with the standard deferred probe mechanism. The deferred probe mode is enabled either via the new option i8042.probe_defer or via the quirk table entry. As of this patch, the quirk table contains only ASUS ZenBook UX425UA. The deferred probe part is based on Fabio's initial work.

Some automated builds report a stack frame size in excess of 2 kB for iqs626_probe(); the culprit appears to be the call to iqs626_parse_prop(). To solve this problem, specify noinline_for_stack for all of the iqs626_parse_*() helper functions which are called inside a for loop within iqs626_parse_prop(). As a result, a build with '-Wframe-larger-than' as low as 512 is free of any such warnings.

Unless the controller is not responding at boot or after suspend/resume, the driver never resets the controller on x86/ACPI platforms. The driver still requesting the reset pin at probe() though in case it needs it. Until now the driver has always requested the reset pin with GPIOD_IN as type. The idea being to put the pin in high-impedance mode to save power until the driver actually wants to issue a reset. But this means that just requesting the pin can cause issues, since requesting it in another mode then GPIOD_ASIS may cause the pinctrl driver to touch the pin settings. We have already had issues before due to a bug in the pinctrl-cherryview.c driver which has been fixed in commit 921daee ("pinctrl: cherryview: Preserve CHV_PADCTRL1_INVRXTX_TXDATA flag on GPIOs"). And now it turns out that requesting the reset-pin as GPIOD_IN also stops the touchscreen from working on the GPD P2 max mini-laptop. The behavior of putting the pin in high-impedance mode relies on there being some external pull-up to keep it high and there seems to be no pull-up on the GPD P2 max, causing things to break. This commit fixes this by requesting the reset pin as is when using the x86/ACPI code paths to lookup the GPIOs; and by not dropping it back into input-mode in case the driver does end up issuing a reset for error-recovery.

The semantics of the rlimit max values differs from ucounts itself. When creating a new userns, we store the current rlimit of the process in ucount_max. Thus, the value of the limit in the parent userns is saved in the created one. The problem is that now we are taking the maximum value for counter from the same userns. So for init_user_ns it will always be RLIM_INFINITY. To fix the problem we need to check the counter value with the max value stored in userns.

...and gpio-ranges pinctrl-bcm2835 is a combined pinctrl/gpio driver. Currently the gpio side is registered first, but this breaks gpio hogs (which are configured during gpiochip_add_data). Part of the hog initialisation is a call to pinctrl_gpio_request, and since the pinctrl driver hasn't yet been registered this results in an -EPROBE_DEFER from which it can never recover. Change the initialisation sequence to register the pinctrl driver first. This also solves a similar problem with the gpio-ranges property, which is required in order for released pins to be returned to inputs.

The detect function had a comment "Make compiler happy" when id did not read the second configuration register. As it turns out, the code was checking the contents of this register for manufacturer ID 0xA1 (NXP Semiconductor/Philips), but never actually read the register. So it wasn't surprising that the compiler complained, and it indeed had a point. Fix the code to read the register contents for manufacturer ID 0xa1. At the same time, the code was reading the register for manufacturer ID 0x41 (Analog Devices), but it was not using the results. In effect it was just checking if reading the register returned an error. That doesn't really add much if any value, so stop doing that.

In commit 41ca9ca ("drm/mediatek: hdmi: Add check for CEA modes only") a check for CEA modes was added to function mtk_hdmi_bridge_mode_valid() in order to address possible issues on MT8167; moreover, with commit c91026a ("drm/mediatek: hdmi: Add optional limit on maximal HDMI mode clock") another similar check was introduced. Unfortunately though, at the time of writing, MT8173 does not provide any mtk_hdmi_conf structure and this is crashing the kernel with NULL pointer upon entering mtk_hdmi_bridge_mode_valid(), which happens as soon as a HDMI cable gets plugged in. To fix this regression, add a NULL pointer check for hdmi->conf in the said function, restoring HDMI functionality and avoiding NULL pointer kernel panics.

Commit 8633ef8 ("drivers/firmware: consolidate EFI framebuffer setup for all arches") made the Generic System Framebuffers (sysfb) driver able to be built on non-x86 architectures. But it left the efifb_setup_from_dmi() function prototype declaration in the architecture specific headers. This could lead to the following compiler warning as reported by the kernel test robot: drivers/firmware/efi/sysfb_efi.c:70:6: warning: no previous prototype for function 'efifb_setup_from_dmi' [-Wmissing-prototypes] void efifb_setup_from_dmi(struct screen_info *si, const char *opt) ^ drivers/firmware/efi/sysfb_efi.c:70:1: note: declare 'static' if the function is not intended to be used outside of this translation unit void efifb_setup_from_dmi(struct screen_info *si, const char *opt) Fixes: 8633ef8 ("drivers/firmware: consolidate EFI framebuffer setup for all arches") Reported-by: kernel test robot <lkp@intel.com> Cc: <stable@vger.kernel.org> # 5.15.x Signed-off-by: Javier Martinez Canillas <javierm@redhat.com> Acked-by: Thomas Zimmermann <tzimmermann@suse.de> Link: https://lore.kernel.org/r/20211126001333.555514-1-javierm@redhat.com Signed-off-by: Ard Biesheuvel <ardb@kernel.org>

I find that we can easily reproduce this problem with the following
commands:
cat /sys/kernel/debug/kfence/objects
echo scan > /sys/kernel/debug/kmemleak
cat /sys/kernel/debug/kmemleak
The leaked memory is allocated in the stack below:
do_syscall_64
do_sys_open
do_dentry_open
full_proxy_open
seq_open ---> alloc seq_file
vfs_read
full_proxy_read
seq_read
seq_read_iter
traverse ---> alloc seq_buf
And it should have been released in the following process:
do_syscall_64
syscall_exit_to_user_mode
exit_to_user_mode_prepare
task_work_run
____fput
__fput
full_proxy_release ---> free here
However, the release function corresponding to file_operations is not
implemented in kfence. As a result, a memory leak occurs. Therefore,
the solution to this problem is to implement the corresponding release
function.

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 ac5b2c1
("mm: thp: relax __GFP_THISNODE for MADV_HUGEPAGE mappings").
The bug disappeared later in the commit 89c83fb ("mm, thp:
consolidate THP gfp handling into alloc_hugepage_direct_gfpmask") and
reappeared again in slightly different form in the commit 76e654c
("mm, page_alloc: allow hugepage fallback to remote nodes when
madvised")
Fix this by passing correct nodemask to the __alloc_pages() call.

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=.

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 b985194 ("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: Naoya Horiguchi <naoya.horiguchi@nec.com> Reported-by: Fei Luo <luofei@unicloud.com> Reviewed-by: Mike Kravetz <mike.kravetz@oracle.com> Cc: <stable@vger.kernel.org> [5.14+] Signed-off-by: Andrew Morton <akpm@linux-foundation.org> Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>
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.
