FROMLIST: scsi: core: Retry passthrough commands if SCMD_RETRY_PASSTHROUGH is set
The SCSI core does not retry passthrough commands even if the SCSI device reports a retryable unit attention condition. Support retrying in this case by introducing the SCMD_RETRY_PASSTHROUGH flag.

UPSTREAM: ring-buffer: Fix a race between readers and resize checks
The reader code in rb_get_reader_page() swaps a new reader page into the
ring buffer by doing cmpxchg on old->list.prev->next to point it to the
new page. Following that, if the operation is successful,
old->list.next->prev gets updated too. This means the underlying
doubly-linked list is temporarily inconsistent, page->prev->next or
page->next->prev might not be equal back to page for some page in the
ring buffer.
The resize operation in ring_buffer_resize() can be invoked in parallel.
It calls rb_check_pages() which can detect the described inconsistency
and stop further tracing:

Note that ring_buffer_resize() calls rb_check_pages() only if the parent
trace_buffer has recording disabled. Recent commit d78ab792705c
("tracing: Stop current tracer when resizing buffer") causes that it is
now always the case which makes it more likely to experience this issue.
The window to hit this race is nonetheless very small. To help
reproducing it, one can add a delay loop in rb_get_reader_page():
ret = rb_head_page_replace(reader, cpu_buffer->reader_page);
if (!ret)
goto spin;
for (unsigned i = 0; i < 1U << 26; i++) /* inserted delay loop */
__asm__ __volatile__ ("" : : : "memory");
rb_list_head(reader->list.next)->prev = &cpu_buffer->reader_page->list;
.. and then run the following commands on the target system:
echo 1 > /sys/kernel/tracing/events/sched/sched_switch/enable
while true; do
echo 16 > /sys/kernel/tracing/buffer_size_kb; sleep 0.1
echo 8 > /sys/kernel/tracing/buffer_size_kb; sleep 0.1
done &
while true; do
for i in /sys/kernel/tracing/per_cpu/*; do
timeout 0.1 cat $i/trace_pipe; sleep 0.2
done
done
To fix the problem, make sure ring_buffer_resize() doesn't invoke
rb_check_pages() concurrently with a reader operating on the same
ring_buffer_per_cpu by taking its cpu_buffer->reader_lock.

UPSTREAM: lib/build_OID_registry: avoid non-destructive substitution for Perl < 5.13.2 compat
On a system with Perl 5.12.1, commit 5ef6dc08cfde
("lib/build_OID_registry: don't mention the full path of the script in
output") causes the build to fail with the error below.
Bareword found where operator expected at ./lib/build_OID_registry line 41, near "s#^\Q$abs_srctree/\E##r"
syntax error at ./lib/build_OID_registry line 41, near "s#^\Q$abs_srctree/\E##r"
Execution of ./lib/build_OID_registry aborted due to compilation errors.
make[3]: *** [lib/Makefile:352: lib/oid_registry_data.c] Error 255
Ahmad Fatoum analyzed that non-destructive substitution is only supported since
Perl 5.13.2. Instead of dropping `r` and having the side effect of modifying
`$0`, introduce a dedicated variable to support older Perl versions.

UPSTREAM: lib/build_OID_registry: don't mention the full path of the script in output
This change strips the full path of the script generating lib/oid_registry_data.c to just lib/build_OID_registry. The motivation for this change is Yocto emitting a build warning File /usr/src/debug/linux-lxatac/6.7-r0/lib/oid_registry_data.c in package linux-lxatac-src contains reference to TMPDIR [buildpaths] So this change brings us one step closer to make the build result reproducible independent of the build path.

ANDROID: vendor_hooks: vendor hooks for optimizing the blocking problem
caused by rwsem lock contention of reverse mapping during memory recycling. Dear Sir， We want to apply the following five trace hook: 1、trace_android_vh_do_folio_trylock() 2、trace_android_vh_get_folio_trylock_result() 3、trace_android_vh_folio_trylock_clear() 4、trace_android_vh_folio_trylock_set() 5、trace_android_vh_handle_trylock_failed_folio(). The optimization objectives are as follows: In the process of memory recycling,reverse mapping is indispensable. The role of reverse mapping is to find all vma or page tables mapped to this page through physical address or page structure. Therefore,the process of reverse mapping will inevitably bring synchronous operations. Whether it is file page or an anonymous page,the synchronization operation is realized through the rwsem read-write lock. Therefore,when kswapd or the user's key thread enters direct_reclaim,the rwsem lock will cause the entire recycling link to be blocked,resulting in low memory recycling efficiency and affecting the user experience. On Xiaomi mobile phones,there is a situation in which the reverse mapping is stuck in the rwsem read-write lock during the file page recycling process,causing the entire recycling link to be blocked,so that the memory cannot be recycled in time. The display on the trace shows that there are a large number of D states,and its block function is rmap_walk_file,therefore,for non-forced recycling scenarios,try_lock and asynchronous recycling are used to handle related blocked pages.

BACKPORT: gpio: of: support gpio-ranges for multiple gpiochip devices
Some drivers (e.g. gpio-mt7621 and gpio-brcmstb) have multiple gpiochip banks within a single device. Unfortunately, the gpio-ranges property of the device node was being applied to every gpiochip of the device with device relative GPIO offset values rather than gpiochip relative GPIO offset values. This commit makes use of the gpio_chip offset value which can be non-zero for such devices to split the device node gpio-ranges property into GPIO offset ranges that can be applied to each of the relevant gpiochips of the device.

ANDROID: Incremental fs: Retry page faults on non-fatal errors
In order to not freeze on corrupt data, we need to turn off FAULT_FLAG_ALLOW_RETRY. However, this means we no longer retry on EINTR, so an interrupted read will lead to page faults. The fault handler does not seem to allow dynamic decisions as to whether to turn on or off this flag. To resolve both issues, add a flag to indicate if there are corrupt pages in a file, and only if there are turn off this flag. Also fsanitize changed the behavior of mlock - mlock should fail if the page reads fail, but with fsanitize it returns 0 then page faults on access. This broke this test, and fsanitize offers little value on test code, so disable it.

UPSTREAM: net: usb: ax88179_178a: improve reset check
After ecf848eb934b ("net: usb: ax88179_178a: fix link status when link is
set to down/up") to not reset from usbnet_open after the reset from
usbnet_probe at initialization stage to speed up this, some issues have
been reported.
It seems to happen that if the initialization is slower, and some time
passes between the probe operation and the open operation, the second reset
from open is necessary too to have the device working. The reason is that
if there is no activity with the phy, this is "disconnected".
In order to improve this, the solution is to detect when the phy is
"disconnected", and we can use the phy status register for this. So we will
only reset the device from reset operation in this situation, that is, only
if necessary.
The same bahavior is happening when the device is stopped (link set to
down) and later is restarted (link set to up), so if the phy keeps working
we only need to enable the mac again, but if enough time passes between the
device stop and restart, reset is necessary, and we can detect the
situation checking the phy status register too.

UPSTREAM: net: usb: ax88179_178a: fix link status when link is set to down/up
The idea was to keep only one reset at initialization stage in order to reduce the total delay, or the reset from usbnet_probe or the reset from usbnet_open. I have seen that restarting from usbnet_probe is necessary to avoid doing too complex things. But when the link is set to down/up (for example to configure a different mac address) the link is not correctly recovered unless a reset is commanded from usbnet_open. So, detect the initialization stage (first call) to not reset from usbnet_open after the reset from usbnet_probe and after this stage, always reset from usbnet_open too (when the link needs to be rechecked). Apply to all the possible devices, the behavior now is going to be the same.

Userspace provided string 's' could trivially have the length zero. Left
unchecked this will firstly result in an OOB read in the form
`if (str[0 - 1] == '\n') followed closely by an OOB write in the form
`str[0 - 1] = '\0'`.
There is already a validating check to catch strings that are too long.
Let's supply an additional check for invalid strings that are too short.

* new (say invalid) source caps are advertised
* the existing source caps are unregistered
* tcpm_register_source_caps() returns with an error as

This causes port->partner_source_caps to hold on to the now freed source
caps.
Reset port->partner_source_caps value to NULL after unregistering

FROMGIT: scsi: ufs: core: Suspend clk scaling on no request
Currently UFS clk scaling is getting suspended only when the clks are scaled down. When high load is generated, a huge amount of latency is added due to scaling up the clk and completing the request post that. Suspending the scaling in its existing state when high load is generated improves the random performance KPI by 28%. So suspending the scaling when there are no requests. And the clk would be put in low scaled state when the actual request load is low. Make this change optional by having the check enabled using vops since for some devices suspending without bringing the clk in low scaled state might have impact on power consumption of the SoC. The change takes advantage of the hole in 'struct ufs_clk_scaling' before ANDROID_KABI_RESERVE and does not change the size of the struct. Use __GENKSYMS__ marker to preserve the abi correctly.

ANDROID: 16K: Don't set padding vm_flags on 32-bit archs
vma_pad_fixup_flags() and is_mergable_pad_vma() were inadvertently affecting the vm_flags on 32-bit arch, making some VMAs not mergable. This causes zygote to crash as the Art GC's heap compaction fails. The compaction depends on mremap() which will fail when operating on a range that spans multiple VMAs [1]. This can happen now due to the incorrect is_mergable_pad_vma() check. Make all the pgsize_migration APIs no-ops in 32-bit architectures, since Android only performs ELF segment extension in 64-bit archs.

ANDROID: mm: swap: export and whitelist get_shadow_from_swap_cache
The shadow entry in the swapcache contains information about a page that got swapped out during the reclaim which is then used at the time of refault to determine if a page is going to be a workingset or not. Once the page is swapped out, vendors can implement some algorithms on the swap area to determine if that page can be further pushed down to slower devices, Eg: say from costly and faster disk to slower disk. But if a page that is actively used is pushed to slower disk, the swapin is going to consume time which can show up in PSI events. The side effect of increased PSI events is, an example, increased kills by LMKD. Alternatively, vendors can rely on the information stored in the swapcache and determine if that particular page in the swap can be further pushed down to slower devices.

ANDROID: mm: madvise: vendor hook to tune page flags
Users can proactively reclaim the pages of an app once it is in background using the system calls, like madvise. But it may be possible that such pages turn out to be the workingset page in the conventional LRU which while swapping can result into accounting of PSI events. Although this PSI events is an indication that wrong pages are being madvised, one can also argue that he is aware of what he is doing using madvise. For such clients, add the vendor hook to tune page flags, such as clearing the Workingset during swapout so that PSI might not get accounyted during swapin.

ANDROID: GKI: Add initialization for rwsem's oem_data and vendor_data.
Add initialization for rwsem's oem_data and vendor_data. The __init_rwsem() already contains a hook, but this function may be called before the rwsem_init hook is registered, causing some rwsem's oem_data to be uninitialized and causing unpredictable errors Bug: 351133539 Change-Id: I7bbb83894d200102bc7d84e91678f164529097a0 Signed-off-by: zhujingpeng <zhujingpeng@vivo.com> (cherry picked from commit aaca6b10f1a352dec4596548396f590500f2001b) |

UPSTREAM: usb: dwc3: core: Skip setting event buffers for host only controllers
On some SoC's like SA8295P where the tertiary controller is host-only capable, GEVTADDRHI/LO, GEVTSIZ, GEVTCOUNT registers are not accessible. Trying to access them leads to a crash. For DRD/Peripheral supported controllers, event buffer setup is done again in gadget_pullup. Skip setup or cleanup of event buffers if controller is host-only capable.
