[PATCH] scsi: target: core: add missing file_{start,end}_write()

by Amir Goldstein

The callers of vfs_iter_write() are required to hold file_start_write(). file_start_write() is a no-op for the S_ISBLK() case, but it is really needed when the backing file is a regular file. We are going to move file_{start,end}_write() into vfs_iter_write(), but we need to fix this first, so that the fix could be backported to stable kernels. Suggested-by: Christoph Hellwig <hch(a)lst.de> Link: https://lore.kernel.org/r/ZV8ETIpM+wZa33B5@infradead.org/ Cc: stable(a)vger.kernel.org Signed-off-by: Amir Goldstein <amir73il(a)gmail.com> --- Hi Martin, This bug is already fixed by commit "fs: move file_start_write() into vfs_iter_write()" on the vfs.rw branch in Christian's vfs tree, but Christoph suggested that I post a separate backportable fix for the scsi target code. You may decide if this is worth expediting to v6.7-rc or not. If not, then I think it would be best if Christian insert this patch at the bottom of the vfs.rw branch and revert in the later aformentioned commit. If you prefer to expedite it to v6.7-rc, then it's probably best to rebase vfs.rw branch after the fix hits master. Please let us know how you prefer to handle this patch.

[nacked] mmoom_reaper-avoid-run-queue_oom_reaper-if-task-is-not-oom.patch removed from -mm tree

by Andrew Morton

The quilt patch titled Subject: mm,oom_reaper: avoid run queue_oom_reaper if task is not oom has been removed from the -mm tree. Its filename was mmoom_reaper-avoid-run-queue_oom_reaper-if-task-is-not-oom.patch This patch was dropped because it was nacked ------------------------------------------------------ From: gaoxu <gaoxu2(a)hihonor.com> Subject: mm,oom_reaper: avoid run queue_oom_reaper if task is not oom Date: Wed, 22 Nov 2023 12:46:44 +0000 queue_oom_reaper() tests and sets tsk->signal->oom_mm->flags. However, it is necessary to check if 'tsk' is an OOM victim before executing 'queue_oom_reaper' because the variable may be NULL. We encountered such an issue, and the log is as follows: [3701:11_see]Out of memory: Killed process 3154 (system_server) total-vm:23662044kB, anon-rss:0kB, file-rss:0kB, shmem-rss:0kB, UID:1000 pgtables:4056kB oom_score_adj:-900 [3701:11_see][RB/E]rb_sreason_str_set: sreason_str set null_pointer [3701:11_see][RB/E]rb_sreason_str_set: sreason_str set unknown_addr [3701:11_see]Unable to handle kernel NULL pointer dereference at virtual address 0000000000000328 [3701:11_see]user pgtable: 4k pages, 39-bit VAs, pgdp=3D00000000821de000 [3701:11_see][0000000000000328] pgd=3D0000000000000000, p4d=3D0000000000000000,pud=3D0000000000000000 [3701:11_see]tracing off [3701:11_see]Internal error: Oops: 96000005 [#1] PREEMPT SMP [3701:11_see]Call trace: [3701:11_see] queue_oom_reaper+0x30/0x170 [3701:11_see] __oom_kill_process+0x590/0x860 [3701:11_see] oom_kill_process+0x140/0x274 [3701:11_see] out_of_memory+0x2f4/0x54c [3701:11_see] __alloc_pages_slowpath+0x5d8/0xaac [3701:11_see] __alloc_pages+0x774/0x800 [3701:11_see] wp_page_copy+0xc4/0x116c [3701:11_see] do_wp_page+0x4bc/0x6fc [3701:11_see] handle_pte_fault+0x98/0x2a8 [3701:11_see] __handle_mm_fault+0x368/0x700 [3701:11_see] do_handle_mm_fault+0x160/0x2cc [3701:11_see] do_page_fault+0x3e0/0x818 [3701:11_see] do_mem_abort+0x68/0x17c [3701:11_see] el0_da+0x3c/0xa0 [3701:11_see] el0t_64_sync_handler+0xc4/0xec [3701:11_see] el0t_64_sync+0x1b4/0x1b8 [3701:11_see]tracing off Link: https://lkml.kernel.org/r/400d13bddb524ef6af37cb2220808c75@hihonor.com Signed-off-by: Gao Xu <gaoxu2(a)hihonor.com> Cc: Suren Baghdasaryan <surenb(a)google.com> Cc: Michal Hocko <mhocko(a)suse.com> Cc: <stable(a)vger.kernel.org> Signed-off-by: Andrew Morton <akpm(a)linux-foundation.org> --- mm/oom_kill.c | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-) --- a/mm/oom_kill.c~mmoom_reaper-avoid-run-queue_oom_reaper-if-task-is-not-oom +++ a/mm/oom_kill.c @@ -984,7 +984,7 @@ static void __oom_kill_process(struct ta } rcu_read_unlock(); - if (can_oom_reap) + if (can_oom_reap && tsk_is_oom_victim(victim)) queue_oom_reaper(victim); mmdrop(mm); _ Patches currently in -mm which might be from gaoxu2(a)hihonor.com are

[PATCH -stable,5.4 00/26] Netfilter stable fixes for 5.4

by Pablo Neira Ayuso

Hi Greg, Sasha, The batch contains Netfilter fixes for -stable 5.4. This batch is targeting at garbage collection (GC) / set timeout fixes that address possible UaF and memleaks as well as assorted bugs.

As a result, the warning messages will often appear in the system log when the system accesses the GL9755 PCI config. Therefore, the replay timer timeout must be masked.

Fwd: dwc3: regression in USB DWC3 driver in kernel 5.15 branch

by Bagas Sanjaya

Hi, I notice a stable-specific regression on Bugzilla [1]. Quoting from it: > The backport commit to 5.15 branch: > 9d4f84a15f9c9727bc07f59d9dafc89e65aadb34 "arm64: dts: imx8mp: Add snps,gfladj-refclk-lpm-sel quirk to USB nodes" (from upstream commit 5c3d5ecf48ab06c709c012bf1e8f0c91e1fcd7ad) > switched from "snps,dis-u2-freeclk-exists-quirk" to "snps,gfladj-refclk-lpm-sel-quirk". > > The problem is that the gfladj-refclk-lpm-sel-quirk quirk is not implemented / backported to 5.15 branch. > > This commit should be either reverted, or the commit introducing gfladj-refclk-lpm-sel-quirk needs to be merged to 5.15 kernel branch. > > As a result of this patch, on Gateworks Venice GW7400 revB board the USB 3.x devices which are connected to the USB Type C port does not enumerate and the following errors are generated: > > [ 14.906302] xhci-hcd xhci-hcd.0.auto: Timeout while waiting for setup device command > [ 15.122383] usb 2-1: device not accepting address 2, error -62 > [ 25.282195] xhci-hcd xhci-hcd.0.auto: Abort failed to stop command ring: -110 > [ 25.297408] xhci-hcd xhci-hcd.0.auto: xHCI host controller not responding, assume dead > [ 25.305345] xhci-hcd xhci-hcd.0.auto: HC died; cleaning up > [ 25.311058] xhci-hcd xhci-hcd.0.auto: Timeout while waiting for stop endpoint command > [ 25.334361] usb usb2-port1: couldn't allocate usb_device > > When the commit is reverted the USB 3.x drives works fine. See Bugzilla for the full thread and attach dmesgs. Anyway, I'm adding it to regzbot: #regzbot introduced: 9d4f84a15f9c97 https://bugzilla.kernel.org/show_bug.cgi?id=217670 #regzbot title: regression in USB DWC3 driver due to missing gfladj-refclk-lpm-sel-quirk quirk Thanks.

Change directory to the tracefs directory 2. Create a kprobe event (doesn't matter what one) 3. Open bash file descriptor 5 on the enable file of the kprobe event 4. Delete the kprobe event (removes the files too) 5. Close the bash file descriptor 5 The above causes a crash! BUG: kernel NULL pointer dereference, address: 0000000000000028 #PF: supervisor read access in kernel mode #PF: error_code(0x0000) - not-present page PGD 0 P4D 0 Oops: 0000 [#1] PREEMPT SMP PTI CPU: 6 PID: 877 Comm: bash Not tainted 6.5.0-rc4-test-00008-g2c6b6b1029d4-dirty #186 Hardware name: QEMU Standard PC (Q35 + ICH9, 2009), BIOS 1.16.2-debian-1.16.2-1 04/01/2014 RIP: 0010:tracing_release_file_tr+0xc/0x50 What happens here is that the kprobe event creates a trace_event_file "file" descriptor that represents the file in tracefs to the event. It maintains state of the event (is it enabled for the given instance?). Opening the "enable" file gets a reference to the event "file" descriptor via the open file descriptor. When the kprobe event is deleted, the file is also deleted from the tracefs system which also frees the event "file" descriptor. But as the tracefs file is still opened by user space, it will not be totally removed until the final dput() is called on it. But this is not true with the event "file" descriptor that is already freed. If the user does a write to or simply closes the file descriptor it will reference the event "file" descriptor that was just freed, causing a use-after-free bug. To solve this, add a ref count to the event "file" descriptor as well as a new flag called "FREED". The "file" will not be freed until the last reference is released. But the FREE flag will be set when the event is removed to prevent any more modifications to that event from happening, even if there's still a reference to the event "file" descriptor.

[PATCH 4.19.y] iomap: Set all uptodate bits for an Uptodate page

by zhangshida

From: "Matthew Wilcox (Oracle)" <willy(a)infradead.org> commit 4595a298d5563cf76c1d852970f162051fd1a7a6 upstream. For filesystems with block size < page size, we need to set all the per-block uptodate bits if the page was already uptodate at the time we create the per-block metadata. This can happen if the page is invalidated (eg by a write to drop_caches) but ultimately not removed from the page cache. This is a data corruption issue as page writeback skips blocks which are marked !uptodate.

[PATCH 5.15] Backport the fix for CVE-2023-25012 to kernel v5.15

by He Gao

This is the fix of CVE-2023-25012 for kernel v5.15. Upstream commit: https://github.com/torvalds/linux/commit/7644b1a1c9a7ae8ab99175989bfc867605… The affected code is in io_uring/io_uring.c instead of io_uring/fdinfo.c for v5.15. So the patch applies the same change to io_uring/io_uring.c. Thanks!

[stable-4.19 PATCH] scsi: virtio_scsi: limit number of hw queues by nr_cpu_ids

by Kunkun Jiang

From: Dongli Zhang <dongli.zhang(a)oracle.com> [ Upstream commit 1978f30a87732d4d9072a20abeded9fe17884f1b ] When tag_set->nr_maps is 1, the block layer limits the number of hw queues by nr_cpu_ids. No matter how many hw queues are used by virtio-scsi, as it has (tag_set->nr_maps == 1), it can use at most nr_cpu_ids hw queues. In addition, specifically for pci scenario, when the 'num_queues' specified by qemu is more than maxcpus, virtio-scsi would not be able to allocate more than maxcpus vectors in order to have a vector for each queue. As a result, it falls back into MSI-X with one vector for config and one shared for queues. Considering above reasons, this patch limits the number of hw queues used by virtio-scsi by nr_cpu_ids.

It works fine for DCN2 family where degamma ROM and custom curves go to the same color block.

[PATCH] btrfs: fix 64bit compat send ioctl arguments not initializing version member

by David Sterba

When the send protocol versioning was added in 5.16 e77fbf990316 ("btrfs: send: prepare for v2 protocol"), the 32/64bit compat code was not updated (added by 2351f431f727 ("btrfs: fix send ioctl on 32bit with 64bit kernel")), missing the version struct member. The compat code is probably rarely used, nobody reported any bugs. Found by tool https://github.com/jirislaby/clang-struct .

There are four conditions in this function that can be changed at mount time to cause this problem. These four conditions can be divided into two categories: (1) journal_data and EXT4_EXTENTS_FL, which can be changed by ioctl (2) DELALLOC and DIOREAD_NOLOCK, which can be changed by remount The two in the first category have been fixed by commit c8585c6fcaf2 ("ext4: fix races between changing inode journal mode and ext4_writepages") and commit cb85f4d23f79 ("ext4: fix race between writepages and enabling EXT4_EXTENTS_FL") respectively. Two cases in the other category have not yet been fixed, and the above issue is caused by this situation. We refer to the fix for the first category, when applying options during remount, we grab s_writepages_rwsem to avoid racing with writepages ops to trigger this problem.

[Regression] Linux-6.6.2: SRSO kernel log messages incorrect

by Caleb Jorden

Hello, I have noticed on my zen3 and zen4 machines (Ryzen 9 5950x & Ryzen 9 7950x) that the kernel boot log regarding SRSO is suddenly incorrect with the 6.6.2 kernel. I have observed this on a completely mainline/stable kernel that I compile regularly for my machines. With the 6.6.1 and 6.7-rc2 kernels, I see correct boot messages like this: [ 0.161327] Spectre V1 : Mitigation: usercopy/swapgs barriers and __user pointer sanitization [ 0.161329] Spectre V2 : Mitigation: Retpolines [ 0.161330] Spectre V2 : Spectre v2 / SpectreRSB mitigation: Filling RSB on context switch [ 0.161331] Spectre V2 : Spectre v2 / SpectreRSB : Filling RSB on VMEXIT [ 0.161332] Spectre V2 : Enabling Restricted Speculation for firmware calls [ 0.161333] Spectre V2 : mitigation: Enabling conditional Indirect Branch Prediction Barrier [ 0.161335] Spectre V2 : User space: Mitigation: STIBP always-on protection [ 0.161336] Speculative Store Bypass: Mitigation: Speculative Store Bypass disabled via prctl [ 0.161338] Speculative Return Stack Overflow: Mitigation: safe RET However, with the 6.6.2 kernel, I see this: [ 0.164266] Spectre V1 : Mitigation: usercopy/swapgs barriers and __user pointer sanitization [ 0.164268] Spectre V2 : Mitigation: Retpolines [ 0.164269] Spectre V2 : Spectre v2 / SpectreRSB mitigation: Filling RSB on context switch [ 0.164270] Spectre V2 : Spectre v2 / SpectreRSB : Filling RSB on VMEXIT [ 0.164272] Spectre V2 : Enabling Restricted Speculation for firmware calls [ 0.164273] Spectre V2 : mitigation: Enabling conditional Indirect Branch Prediction Barrier [ 0.164275] Spectre V2 : User space: Mitigation: STIBP always-on protection [ 0.164276] Speculative Store Bypass: Mitigation: Speculative Store Bypass disabled via prctl [ 0.164278] Speculative Return Stack Overflow: IBPB-extending microcode not applied! [ 0.164279] Speculative Return Stack Overflow: WARNING: See https://kernel.org/doc/html/latest/admin-guide/hw-vuln/srso.html for mitigation options. [ 0.164280] Speculative Return Stack Overflow: Mitigation: Safe RET Notice that in both cases the final SRSO message indicates (correctly) that my system is protected with Safe RET (because my BIOS has the updated microcode for SRSO). However, in the 6.6.2 kernel I also get the microcode warning. I tracked this down to, what I believe is, the following commit from the mainline kernel not being included in the 6.6.2 patch set: 351236947a45a512c517153bbe109fe868d05e6d x86/srso: Move retbleed IBPB check into existing 'has_microcode' code block When I cherry-pick this commit to the 6.6.2 release, the log messages are correct. Note that this patch does not obviously indicate there is a functional change introduced by applying it. However (at least in the case of Zen3 and Zen4) when the updated microcode has been applied, the flow is different (specifically the situation that falls into the else statement that produces the pr-warn calls to indicate that the microcode fix needs applied). I believe this might be because RETBLEED does not apply to Zen3 and Zen4. Unfortunately I don't have a Zen1 or Zen2 system readily available on which to test this theory. While this should only be a cosmetic change, I believe that there is value in having the correct messages in the kernel logs for SRSO in this LTS release. Please feel free to correct my analysis above if it is incorrect. Warm Regards, Caleb Jorden

Which will cause the dirver have chance to fire hotplug event before restoring the old state. Then Userspace will react to the hotplug event based on a wrong state. [How] Adjust the mst resume flow as: 1. set dpcd to resume mst branch status 2. restore source old state 3. Do mst resume topology probing For drm_dp_mst_topology_mgr_resume(), it's better to adjust it to pull out topology probing work into a 2nd part procedure of the mst resume.

Do mst resume topology probing For drm_dp_mst_topology_mgr_resume(), it's better to adjust it to pull out topology probing work into a 2nd part procedure of the mst resume.

To enforce this behavior, ext4_dio_write_iter() checks the current inline state of the inode and clears the MAY_INLINE_DATA state flag to either fall back to buffered writes, or enforce that any other writers in progress on the inode are not allowed to create inline data. The problem is that the check for existing inline data and the state flag can span a lock cycle. For example, if the ilock is originally locked shared and subsequently upgraded to exclusive, another writer may have reacquired the lock and created inline data before the dio write task acquires the lock and proceeds. The commit referenced below loosens the lock requirements to allow some forms of unaligned dio writes to occur under shared lock, but AFAICT the inline data check was technically already racy for any dio write that would have involved a lock cycle. Regardless, lift clearing of the state bit to the same lock critical section that checks for preexisting inline data on the inode to close the race.

There are four conditions in this function that can be changed at mount time to cause this problem. These four conditions can be divided into two categories: (1) journal_data and EXT4_EXTENTS_FL, which can be changed by ioctl (2) DELALLOC and DIOREAD_NOLOCK, which can be changed by remount The two in the first category have been fixed by commit c8585c6fcaf2 ("ext4: fix races between changing inode journal mode and ext4_writepages") and commit cb85f4d23f79 ("ext4: fix race between writepages and enabling EXT4_EXTENTS_FL") respectively. Two cases in the other category have not yet been fixed, and the above issue is caused by this situation.

[PATCH v2] dmaengine: stm32-dma: avoid bitfield overflow assertion

by Amelie Delaunay

stm32_dma_get_burst() returns a negative error for invalid input, which gets turned into a large u32 value in stm32_dma_prep_dma_memcpy() that in turn triggers an assertion because it does not fit into a two-bit field: drivers/dma/stm32-dma.c: In function 'stm32_dma_prep_dma_memcpy': include/linux/compiler_types.h:354:38: error: call to '__compiletime_assert_282' declared with attribute error: FIELD_PREP: value too large for the field _compiletime_assert(condition, msg, __compiletime_assert_, __COUNTER__) ^ include/linux/compiler_types.h:335:4: note: in definition of macro '__compiletime_assert' prefix ## suffix(); \ ^~~~~~ include/linux/compiler_types.h:354:2: note: in expansion of macro '_compiletime_assert' _compiletime_assert(condition, msg, __compiletime_assert_, __COUNTER__) ^~~~~~~~~~~~~~~~~~~ include/linux/build_bug.h:39:37: note: in expansion of macro 'compiletime_assert' #define BUILD_BUG_ON_MSG(cond, msg) compiletime_assert(!(cond), msg) ^~~~~~~~~~~~~~~~~~ include/linux/bitfield.h:68:3: note: in expansion of macro 'BUILD_BUG_ON_MSG' BUILD_BUG_ON_MSG(__builtin_constant_p(_val) ? \ ^~~~~~~~~~~~~~~~ include/linux/bitfield.h:114:3: note: in expansion of macro '__BF_FIELD_CHECK' __BF_FIELD_CHECK(_mask, 0ULL, _val, "FIELD_PREP: "); \ ^~~~~~~~~~~~~~~~ drivers/dma/stm32-dma.c:1237:4: note: in expansion of macro 'FIELD_PREP' FIELD_PREP(STM32_DMA_SCR_PBURST_MASK, dma_burst) | ^~~~~~~~~~ As an easy workaround, assume the error can happen, so try to handle this by failing stm32_dma_prep_dma_memcpy() before the assertion. It replicates what is done in stm32_dma_set_xfer_param() where stm32_dma_get_burst() is also used.

This change: - fixes writing frame width and height values into CSID_TPG_DT_n_CFG_0 - fixes the shift by one between test_pattern control value and the actual pattern. - drops fixed VC of 0x0a which testing showed prohibited some test patterns in the CSID to produce output. So that TPG starts working, but with the below limitations: - only test_pattern=9 works as it should - test_pattern=8 and test_pattern=7 produce black frame (all zeroes) - the rest of test_pattern's don't work (yavta doesn't get the data) - regardless of the CFA pattern set by 'media-ctl -V' the actual pixel order is always the same (RGGB for any RAW8 or RAW10P format in 4608x2592 resolution).

[REGRESSION] USB ports do not work after suspend/resume cycle with v6.6.2

by Oleksandr Natalenko

Hello. Since v6.6.2 kernel release I'm experiencing a regression with regard to USB ports behaviour after a suspend/resume cycle. If a USB port is empty before suspending, after resuming the machine the port doesn't work. After a device insertion there's no reaction in the kernel log whatsoever, although I do see that the device gets powered up physically. If the machine is suspended with a device inserted into the USB port, the port works fine after resume. This is an AMD-based machine with hci version 0x110 reported. As per the changelog between v6.6.1 and v6.6.2, 603 commits were backported into v6.6.2, and one of the commits was as follows: $ git log --oneline v6.6.1..v6.6.2 -- drivers/usb/host/xhci-pci.c 14a51fa544225 xhci: Loosen RPM as default policy to cover for AMD xHC 1.1 It seems that this commit explicitly enables runtime PM specifically for my platform. As per dmesg: v6.6.1: quirks 0x0000000000000410 v6.6.2: quirks 0x0000000200000410 Here, bit 33 gets set, which, as expected, corresponds to: drivers/usb/host/xhci.h 1895:#define XHCI_DEFAULT_PM_RUNTIME_ALLOW BIT_ULL(33) This commit is backported from the upstream commit 4baf12181509, which is one of 16 commits of the following series named "xhci features": https://lore.kernel.org/all/20231019102924.2797346-1-mathias.nyman@linux.in… It appears that there was another commit in this series, also from Basavaraj (in Cc), a5d6264b638e, which was not picked for v6.6.2, but which stated the following: Use the low-power states of the underlying platform to enable runtime PM. If the platform doesn't support runtime D3, then enabling default RPM will result in the controller malfunctioning, as in the case of hotplug devices not being detected because of a failed interrupt generation. It felt like this was exactly my case. So, I've conducted two tests: 1. Reverted 14a51fa544225 from v6.6.2. With this revert the USB ports started to work fine, just as they did in v6.6.1. 2. Left 14a51fa544225 in place, but also applied upstream a5d6264b638e on top of v6.6.2. With this patch added the USB ports also work after a suspend/resume cycle. This runtime PM enablement did also impact my AX200 Bluetooth device, resulting in long delays before headphones/speaker can connect, but I've solved this with btusb.enable_autosuspend=N. I think this has nothing to do with the original issue, and I'm OK with this workaround unless someone has got a different idea. With that, please consider either reverting 14a51fa544225 from the stable kernel, or applying a5d6264b638e in addition to it. Given the mainline kernel has got both of them, I'm in favour of applying additional commit to the stable kernel. I'm also Cc'ing all the people from our Mastodon discussion where I initially complained about the issue as well as about stable kernel branch stability: https://activitypub.natalenko.name/@oleksandr/statuses/01HFRXBYWMXF9G4KYPE3… I'm not going to expand more on that in this email, especially given Greg indicated he read the conversation, but I'm open to continuing this discussion as I still think that current workflow brings visible issues to ordinary users, and hence some adjustments should be made. Thank you. -- Oleksandr Natalenko (post-factum)

The intention here is to prevent the delay target from re-arming the timer again. However, this test is racy. Suppose that one thread goes to delay_bio, sees that dc->may_delay is one and proceeds; now, another thread executes delay_presuspend, it sets dc->may_delay to zero, deletes the timer and flushes pending bios. Then, the first thread continues and adds the bio to delayed->list despite the fact that dc->may_delay is false. Fix this bug by changing may_delay's type from atomic_t to bool and only access it while holding the delayed_bios_lock mutex.

And before returning from open_cached_dir(), we put the last reference of the new @cfid because of !@cfid->has_lease. Besides the UAF, while running xfstests a lot of missed lease breaks have been noticed in tests that run several concurrent statfs(2) calls on those cached fids CIFS: VFS: \\w22-root1.gandalf.test No task to wake, unknown frame...

In some recent examples this turned out to be a significant problem when trying to analyze performance data - since there are many cases where unless we know the tree id and session id we can't figure out which stats (e.g. number of SMB3.1.1 requests by type, the total time they take, which is slowest, how many fail etc.) apply to which mount. The only existing loosely related ioctl CIFS_IOC_GET_MNT_INFO does not return the information needed to uniquely identify which tcon is which mount although it does return various flags and device info. Add a cifs.ko ioctl CIFS_IOC_GET_TCON_INFO (0x800ccf0c) to return tid, session id, tree connect count.

[PATCH v2 02/10] wifi: rtlwifi: Convert LNKCTL change to PCIe cap RMW accessors

by Ilpo Järvinen

The rtlwifi driver comes with custom code to write into PCIe Link Control register. RMW access for the Link Control register requires locking that is already provided by the standard PCIe capability accessors. Convert the custom RMW code writing into LNKCTL register to standard RMW capability accessors. The accesses are changed to cover the full LNKCTL register instead of touching just a single byte of the register.
