#1596930 — [PATCH 4.10 156/167] xprtrdma: Fix Read chunk padding

4.10-stable review patch.  If anyone has any objections, please let me know.

------------------

From: Chuck Lever <chuck.lever@oracle.com>

commit 24abdf1be15c478e2821d6fc903a4a4440beff02 upstream.

When pad optimization is disabled, rpcrdma_convert_iovs still
does not add explicit XDR round-up padding to a Read chunk.

Commit 677eb17e94ed ("xprtrdma: Fix XDR tail buffer marshalling")
incorrectly short-circuited the test for whether round-up padding
is needed that appears later in rpcrdma_convert_iovs.

However, if this is indeed a regular Read chunk (and not a
Position-Zero Read chunk), the tail iovec _always_ contains the
chunk's padding, and never anything else.

So, it's easy to just skip the tail when padding optimization is
enabled, and add the tail in a subsequent Read chunk segment, if
disabled.

#1596931 — [PATCH 4.10 148/167] f2fs: Fix zoned block device support

4.10-stable review patch.  If anyone has any objections, please let me know.

------------------

From: Masato Suzuki <masato.suzuki@wdc.com>

commit 7bb3a371d199156cb6a863feab377146b80942c5 upstream.

The introduction of the multi-device feature partially broke the support
for zoned block devices. In the function f2fs_scan_devices, sbi->devs
allocation and initialization is skipped in the case of a single device
mount. This result in no device information structure being allocated
for the device. This is fine if the device is a regular device, but in
the case of a zoned block device, the device zone type array is not
initialized, which causes the function __f2fs_issue_discard_zone to fail
as get_blkz_type is unable to determine the zone type of a section.

Fix this by always allocating and initializing the sbi->devs device
information array even in the case of a single device if that device is
zoned. For this particular case, make sure to obtain a reference on the
single device so that the call to blkdev_put() in destroy_device_list
operates as expected.

#1596932 — [PATCH 4.10 157/167] xprtrdma: Per-connection pad optimization

4.10-stable review patch.  If anyone has any objections, please let me know.

------------------

From: Chuck Lever <chuck.lever@oracle.com>

commit b5f0afbea4f2ea52c613ac2b06cb6de2ea18cb6d upstream.

Pad optimization is changed by echoing into
/proc/sys/sunrpc/rdma_pad_optimize. This is a global setting,
affecting all RPC-over-RDMA connections to all servers.

The marshaling code picks up that value and uses it for decisions
about how to construct each RPC-over-RDMA frame. Having it change
suddenly in mid-operation can result in unexpected failures. And
some servers a client mounts might need chunk round-up, while
others don't.

So instead, copy the pad_optimize setting into each connection's
rpcrdma_ia when the transport is created, and use the copy, which
can't change during the life of the connection, instead.

This also removes a hack: rpcrdma_convert_iovs was using
the remote-invalidation-expected flag to predict when it could leave
out Write chunk padding. This is because the Linux server handles
implicit XDR padding on Write chunks correctly, and only Linux
servers can set the connection's remote-invalidation-expected flag.

It's more sensible to use the pad optimization setting instead.

#1596934 — [PATCH 4.10 133/167] rtlwifi: Fix alignment issues

4.10-stable review patch.  If anyone has any objections, please let me know.

------------------

From: Ping-Ke Shih <pkshih@realtek.com>

commit 40b368af4b750863b2cb66a3a9513241db2f0793 upstream.

The addresses of Wlan NIC registers are natural alignment, but some
drivers have bugs. These are evident on platforms that need natural
alignment to access registers.  This change contains the following:
 1. Function _rtl8821ae_dbi_read() is used to read one byte from DBI,
    thus it should use rtl_read_byte().
 2. Register 0x4C7 of 8192ee is single byte.

4.10-stable review patch.  If anyone has any objections, please let me know.

The problem is due to rtl8192ce and rtl8192cu sharing routines, and having
different layouts of struct rtl_pci_priv, which is used by rtl8192ce, and
struct rtl_usb_priv, which is used by rtl8192cu. The problem was resolved
by placing the struct bt_coexist_info at the head of each of those private
areas.

4.10-stable review patch.  If anyone has any objections, please let me know.

------------------

From: K. Y. Srinivasan <kys@microsoft.com>

commit d77044d142e960f7b5f814a91ecb8bcf86aa552c upstream.

VSS may use a char device to support the communication between
the user level daemon and the driver. When the VSS channel is rescinded
we need to make sure that the char device is fully cleaned up before
we can process a new VSS offer from the host. Implement this logic.

When we unlock our spinlock to copy data to user we may get
disabled by USB host and free the whole list of completed out
requests including the one from which we are copying the data
to user memory.

To prevent from this let's remove our working element from
the list and place it back only if there is sth left when we
finish with it.

4.10-stable review patch.  If anyone has any objections, please let me know.

------------------

From: Krzysztof Opasiak <k.opasiak@samsung.com>

commit 8236800da115a3e24b9165c573067343f51cf5ea upstream.

Since:

commit 855ed04a3758 ("usb: gadget: udc-core: independent registration
of gadgets and gadget drivers")

if we load gadget module but there is no free udc available
then it will be stored on a pending gadgets list.

$ modprobe g_zero.ko
$ modprobe g_ether.ko
[] udc-core: couldn't find an available UDC - added [g_ether] to list
of pending drivers

We scan this list each time when new UDC appears in system.
But we can get a free UDC each time after gadget unbind.
This commit add scanning of that list directly after unbinding
gadget from udc.

Thanks to this, when we unload first gadget:

$ rmmod g_zero.ko

gadget which is pending is automatically
attached to that UDC (if name matches).

#1596940 — [PATCH 4.10 126/167] Drivers: hv: util: kvp: Fix a rescind processing issue

4.10-stable review patch.  If anyone has any objections, please let me know.

------------------

From: K. Y. Srinivasan <kys@microsoft.com>

commit 5a66fecbf6aa528e375cbebccb1061cc58d80c84 upstream.

KVP may use a char device to support the communication between
the user level daemon and the driver. When the KVP channel is rescinded
we need to make sure that the char device is fully cleaned up before
we can process a new KVP offer from the host. Implement this logic.

#1596941 — [PATCH 4.10 129/167] RDMA/core: Fix incorrect structure packing for booleans

4.10-stable review patch.  If anyone has any objections, please let me know.

------------------

From: Jason Gunthorpe <jgunthorpe@obsidianresearch.com>

commit 55efcfcd7776165b294f8b5cd6e05ca00ec89b7c upstream.

The RDMA core uses ib_pack() to convert from unpacked CPU structs
to on-the-wire bitpacked structs.

This process requires that 1 bit fields are declared as u8 in the
unpacked struct, otherwise the packing process does not read the
value properly and the packed result is wired to 0. Several
places wrongly used int.

Crucially this means the kernel has never, set reversible
correctly in the path record request. It has always asked for
irreversible paths even if the ULP requests otherwise.

When the kernel is used with a SM that supports this feature, it
completely breaks communication management if reversible paths are
not properly requested.

The only reason this ever worked is because opensm ignores the
reversible bit.

At least macOS seems to be sending
ClearFeature(ENDPOINT_HALT) to endpoints which
aren't Halted. This makes DWC3's CLEARSTALL command
time out which causes several issues for the driver.

Instead, let's just return 0 and bail out early.

4.10-stable review patch.  If anyone has any objections, please let me know.

------------------

From: Krzysztof Opasiak <kopasiak90@gmail.com>

commit 749494b6bdbbaf0899aa1c62a1ad74cd747bce47 upstream.

Since commit: ba1582f22231 ("usb: gadget: f_hid: use alloc_ep_req()")
we cannot allocate any requests in bind() as we check if we should
align request buffer based on endpoint descriptor which is assigned
in set_alt().

Allocating request in bind() function causes a NULL pointer
dereference.

This commit moves allocation of IN request from bind() to set_alt()
to prevent this issue.

#1596955 — [PATCH 4.10 105/167] Revert "arm64: mm: set the contiguous bit for kernel mappings where appropriate"

4.10-stable review patch.  If anyone has any objections, please let me know.

------------------

From: Mark Rutland <mark.rutland@arm.com>

commit d81bbe6d882461dec4b71dbe2aa85565fcca4187 upstream.

This reverts commit 0bfc445dec9dd8130d22c9f4476eed7598524129.

When we change the permissions of regions mapped using contiguous
entries, the architecture requires us to follow a Break-Before-Make
strategy, breaking *all* associated entries before we can change any of
the following properties from the entries:

 - presence of the contiguous bit
 - output address
 - attributes
 - permissiones

Failure to do so can result in a number of problems (e.g. TLB conflict
aborts and/or erroneous results from TLB lookups).

See ARM DDI 0487A.k_iss10775, "Misprogramming of the Contiguous bit",
page D4-1762.

We do not take this into account when altering the permissions of kernel
segments in mark_rodata_ro(), where we change the permissions of live
contiguous entires one-by-one, leaving them transiently inconsistent.
This has been observed to result in failures on some fast model
configurations.

Unfortunately, we cannot follow Break-Before-Make here as we'd have to
unmap kernel text and data used to perform the sequence.

For the timebeing, revert commit 0bfc445dec9dd813 so as to avoid issues
resulting from this misuse of the contiguous bit.
