commit c4ff91dd40e2253ab6dd028011469c2c694e1e19 upstream.

The current use of result is or'ing in values and checking for a non-zero result, however, result is not initialized to zero so it potentially contains garbage to start with. Fix this by initializing it to the first return from the call to vega10_program_didt_config_registers.

Detected by cppcheck: "(error) Uninitialized variable: result"

commit e0bf2d4982fe7d9ddaf550dd023803ea286f47fc upstream.

Apparently, this driver (or the hardware) does not support character length settings. It's apparently running in 8-bit mode, but it makes userspace believe it's in 5-bit mode. That makes tcsetattr with CS8 incorrectly fail, breaking e.g. getty from busybox, thus the login shell on ttyMVx.

Fix by hard-wiring CS8 into c_cflag.

[ Upstream commit 77cfaf52eca5cac30ed029507e0cab065f888995 ]

The TXQ teardown code can reference the vif data structures that are stored in the netdev private memory area if there are still packets on the queue when it is being freed. Since the TXQ teardown code is run after the netdevs are freed, this can lead to a use-after-free. Fix this by moving the TXQ teardown code to earlier in ieee80211_unregister_hw().

[ Upstream commit 46dec40fb741f00f1864580130779aeeaf24fb3d ]

This fixes a bug which causes guest virtual addresses to get translated to guest real addresses incorrectly when the guest is using the HPT MMU and has more than 256GB of RAM, or more specifically has a HPT larger than 2GB. This has showed up in testing as a failure of the host to emulate doorbell instructions correctly on POWER9 for HPT guests with more than 256GB of RAM.

The bug is that the HPTE index in kvmppc_mmu_book3s_64_hv_xlate() is stored as an int, and in forming the HPTE address, the index gets shifted left 4 bits as an int before being signed-extended to 64 bits. The simple fix is to make the variable a long int, matching the return type of kvmppc_hv_find_lock_hpte(), which is what calculates the index.

("gpiolib-acpi: make sure we trigger edge events at least once on boot")

added a initial value check for pin which is about to be locked as IRQ. Unfortunately, not all GPIO drivers can do that atomically. Thus, switch to cansleep version of the call. Otherwise we have a warning:

If there are packets in hardware when changing the speed or duplex, it may cause hardware hang up.

This patch adds the code for waiting chip to clean the all pkts(TX & RX) in chip when the driver uses the function named "adjust link".

This patch cleans the pkts as follows: 1) close rx of chip, close tx of protocol stack. 2) wait rcb, ppe, mac to clean. 3) adjust link 4) open rx of chip, open tx of protocol stack.

In the error path of changing the SKB headroom of the second A-MSDU subframe, we would not account for the already-changed length of the first frame that just got converted to be in A-MSDU format and thus is a bit longer now.

Fix this by doing the necessary accounting.

It would be possible to reorder the operations, but that would make the code more complex (to calculate the necessary pad), and the headroom expansion should not fail frequently enough to make that worthwhile.

[ Upstream commit 1d0ffd264204eba1861865560f1f7f7a92919384 ]

In raid10 reshape_request it gets max_sectors in read_balance. If the underlayer disks have bad blocks, the max_sectors is less than last. It will call goto read_more many times. It calls raise_barrier(conf, sectors_done != 0) every time. In this condition sectors_done is not 0. So the value passed to the argument force of raise_barrier is true.

In raise_barrier it checks conf->barrier when force is true. If force is true and conf->barrier is 0, it panic. In this case reshape_request submits bio to under layer disks. And in the callback function of the bio it calls lower_barrier. If the bio finishes before calling raise_barrier again, it can trigger the BUG_ON.

Add one pair of raise_barrier/lower_barrier to fix this bug.

[ Upstream commit c15e3f19a6d5c89b1209dc94b40e568177cb0921 ]

When a Mac client saves an item containing a backslash to a file server the backslash is represented in the CIFS/SMB protocol as as U+F026. Before this change, listing a directory containing an item with a backslash in its name will return that item with the backslash represented with a true backslash character (U+005C) because convert_sfm_character mapped U+F026 to U+005C when interpretting the CIFS/SMB protocol response. However, attempting to open or stat the path using a true backslash will result in an error because convert_to_sfm_char does not map U+005C back to U+F026 causing the CIFS/SMB request to be made with the backslash represented as U+005C.

This change simply prevents the U+F026 to U+005C conversion from happenning. This is analogous to how the code does not do any translation of UNI_SLASH (U+F000).

The "chandef->center_freq1" variable is a u32 but "freq" is a u16 so we are truncating away the high bits. I noticed this bug because in commit 9cf0a0b4b64a ("cfg80211: Add support for 60GHz band channels 5 and 6") we made "freq <= 56160 + 2160 * 6" a valid requency when before it was only "freq <= 56160 + 2160 * 4" that was valid. It introduces a static checker warning:

When performing a channel switch flow for a managed interface, the flow did not update the bandwidth of the AP station and the rate scale algorithm. In case of a channel width downgrade, this would result with the rate scale algorithm using a bandwidth that does not match the interface channel configuration.

Fix this by updating the AP station bandwidth and rate scaling algorithm before the actual channel change in case of a bandwidth downgrade, or after the actual channel change in case of a bandwidth upgrade.

commit b799207e1e1816b09e7a5920fbb2d5fcf6edd681 upstream.

When I wrote commit 468f6eafa6c4 ("bpf: fix 32-bit ALU op verification"), I assumed that, in order to emulate 64-bit arithmetic with 32-bit logic, it is sufficient to just truncate the output to 32 bits; and so I just moved the register size coercion that used to be at the start of the function to the end of the function.

That assumption is true for almost every op, but not for 32-bit right shifts, because those can propagate information towards the least significant bit. Fix it by always truncating inputs for 32-bit ops to 32 bits.

Also get rid of the coerce_reg_to_size() after the ALU op, since that has no effect.

[ Upstream commit b55326dc969ea2d704a008d9a97583b128f54f4f ]

The interrupt controller hardware in this pin controller has two status enable bits. The first "normal" status enable bit enables or disables the summary interrupt line being raised when a gpio interrupt triggers and the "raw" status enable bit allows or prevents the hardware from latching an interrupt into the status register for a gpio interrupt. Currently we just toggle the "normal" status enable bit in the mask and unmask ops so that the summary irq interrupt going to the CPU's interrupt controller doesn't trigger for the masked gpio interrupt.

For a level triggered interrupt, the flow would be as follows: the pin controller sees the interrupt, latches the status into the status register, raises the summary irq to the CPU, summary irq handler runs and calls handle_level_irq(), handle_level_irq() masks and acks the gpio interrupt, the interrupt handler runs, and finally unmask the interrupt. When the interrupt handler completes, we expect that the interrupt line level will go back to the deasserted state so the genirq code can unmask the interrupt without it triggering again.

If we only mask the interrupt by clearing the "normal" status enable bit then we'll ack the interrupt but it will continue to show up as pending in the status register because the raw status bit is enabled, the hardware hasn't deasserted the line, and thus the asserted state latches into the status register again. When the hardware deasserts the interrupt the pin controller still thinks there is a pending unserviced level interrupt because it latched it earlier. This behavior causes software to see an extra interrupt for level type interrupts each time the interrupt is handled.

Let's fix this by clearing the raw status enable bit for level type interrupts so that the hardware stops latching the status of the interrupt after we ack it. We don't do this for edge type interrupts because it seems that toggling the raw status enable bit for edge type interrupts causes spurious edge interrupts.

This reverts commit 535fba29b3e1afef4ba201b3c69a6992583ec0bd.

Seems the submitter (er me, hang head in shame) didn't look at the datasheet enough to see that the registers are quite different.

This needs to be reverted because a) would never work b) to open it be added to a Maxim RTDs (Resistance Temperature Detectors) under development by author

Commit b0f847e16c1e ("HID: hid-sensor-hub: Force logical minimum to 1 for power and report state") not only replaced the descriptor fixup done for devices with the HID_SENSOR_HUB_ENUM_QUIRK with a generic fix, but also accidentally removed the unrelated descriptor fixup for the Lenovo ThinkPad Helix 2 sensor hub. This commit restores this fixup.

Restoring this fixup not only fixes the Lenovo ThinkPad Helix 2's sensors, but also the Lenovo ThinkPad 8's sensors.

[ Upstream commit 8407879c4e0d7731f6e7e905893cecf61a7762c7 ]

Currently we always repost the recv buffer before we send a response capsule back to the host. Since ordering is not guaranteed for send and recv completions, it is posible that we will receive a new request from the host before we got a send completion for the response capsule.

Today, we pre-allocate 2x rsps the length of the queue, but in reality, under heavy load there is nothing that is really preventing the gap to expand until we exhaust all our rsps.

To fix this, if we don't have any pre-allocated rsps left, we dynamically allocate a rsp and make sure to free it when we are done. If under memory pressure we fail to allocate a rsp, we silently drop the command and wait for the host to retry.

The buffer length field in the ena rx descriptor is 16 bit, and the current driver passes a full page in each ena rx descriptor. When PAGE_SIZE equals 64kB or more, the buffer length field becomes zero. To solve this issue, limit the ena Rx descriptor to use 16kB even when allocating 64kB kernel pages. This change would not impact ena device functionality, as 16kB is still larger than maximum MTU.

Cause:

As mentioned in Software Development Manual vol 3, 17.4.8.1, IA32_PERF_CAPABILITIES[5:0] indicates the format of the address that is stored in the LBR stack. Knights Landing reports 1 (LBR_FORMAT_LIP) as its format. Despite that, registers containing FROM address of the branch, do have MISPREDICT bit but because of the format indicated in IA32_PERF_CAPABILITIES[5:0], LBR did not read MISPREDICT bit.

Solution:

Teach LBR about above Knights Landing quirk and make it read MISPREDICT bit.

[ Upstream commit 5c41aaad409c097cf1ef74f2c649fed994744ef5 ]

Building drivers/mtd/nand/raw/nandsim.c on arch/hexagon/ produces a printk format build warning. This is due to hexagon's ffs() being coded as returning long instead of int.

Fix the printk format warning by changing all of hexagon's ffs() and fls() functions to return int instead of long. The variables that they return are already int instead of long. This return type matches the return type in <asm-generic/bitops/>.

../drivers/mtd/nand/raw/nandsim.c: In function 'init_nandsim': ../drivers/mtd/nand/raw/nandsim.c:760:2: warning: format '%u' expects argument of type 'unsigned int', but argument 2 has type 'long int' [-Wformat]

There are no ffs() or fls() allmodconfig build errors after making this change.

[ Upstream commit aec45e857c5538664edb76a60dd452e3265f37d1 ]

qeth_query_oat_command() currently allocates the kernel buffer for the SIOC_QETH_QUERY_OAT ioctl with kzalloc. So on systems with fragmented memory, large allocations may fail (eg. the qethqoat tool by default uses 132KB).

Solve this issue by using vzalloc, backing the allocation with non-contiguous memory.

This happens because handle_vcpu_hotplug_event is called twice. In the first iteration cpu_present is still true, in the second iteration cpu_present is false which causes get_cpu_device to return NULL. In case of cpu#0, cpu_online is apparently always true.

Fix this crash by checking if the cpu can be hotplugged, which is false for a cpu that was just removed.

Also check if the cpu was actually offlined by device_remove, otherwise leave the cpu_present state as it is.

Rearrange to code to do all work with device_hotplug_lock held.

commit 0595751f267994c3c7027377058e4185b3a28e75 upstream.

When mounting a Windows share that is the root of a drive (eg. C$) the server does not return . and .. directory entries. This results in the smb2 code path erroneously skipping the 2 first entries.

Pseudo-code of the readdir() code path:

cifs_readdir(struct file, struct dir_context) initiate_cifs_search <-- if no reponse cached yet server->ops->query_dir_first

dir_emit_dots dir_emit <-- adds "." and ".." if we're at pos=0

find_cifs_entry initiate_cifs_search <-- if pos < start of current response (restart search) server->ops->query_dir_next <-- if pos > end of current response (fetch next search res)

for(...) <-- loops over cur response entries starting at pos cifs_filldir <-- skip . and .., emit entry cifs_fill_dirent dir_emit pos++

A) dir_emit_dots() always adds . & .. and sets the current dir pos to 2 (0 and 1 are done).

Therefore we always want the index_to_find to be 2 regardless of if the response has . and ..

B) smb1 code initializes index_of_last_entry with a +2 offset

in cifssmb.c CIFSFindFirst(): psrch_inf->index_of_last_entry = 2 /* skip . and .. */ + psrch_inf->entries_in_buffer;

Later in find_cifs_entry() we want to find the next dir entry at pos=2 as a result of (A)

first_entry_in_buffer = cfile->srch_inf.index_of_last_entry - cfile->srch_inf.entries_in_buffer;

This var is the dir pos that the first entry in the buffer will have therefore it must be 2 in the first call.

If we don't offset index_of_last_entry by 2 (like in (B)), first_entry_in_buffer=0 but we were instructed to get pos=2 so this code in find_cifs_entry() skips the 2 first which is ok for non-root shares, as it skips . and .. from the response but is not ok for root shares where the 2 first are actual files

pos_in_buf = index_to_find - first_entry_in_buffer; // pos_in_buf=2 // we skip 2 first response entries :( for (i = 0; (i < (pos_in_buf)) && (cur_ent != NULL); i++) { /* go entry by entry figuring out which is first */ cur_ent = nxt_dir_entry(cur_ent, end_of_smb, cfile->srch_inf.info_level); }

C) cifs_filldir() skips . and .. so we can safely ignore them for now.

Sample program:

int main(int argc, char **argv) { const char *path = argc >= 2 ? argv[1] : "."; DIR *dh; struct dirent *de;

printf("listing path <%s>\n", path); dh = opendir(path); if (!dh) { printf("opendir error %d\n", errno); return 1; }

while (1) { de = readdir(dh); if (!de) { if (errno) { printf("readdir error %d\n", errno); return 1; } printf("end of listing\n"); break; } printf("off=%lu <%s>\n", de->d_off, de->d_name); }

return 0; }

Before the fix with SMB1 on root shares:

<.> off=1 <..> off=2 <$Recycle.Bin> off=3 <bootmgr> off=4

and on non-root shares:

<.> off=1 <..> off=4 <-- after adding .., the offsets jumps to +2 because <2536> off=5 we skipped . and .. from response buffer (C) <411> off=6 but still incremented pos <file> off=7 <fsx> off=8

Therefore the fix for smb2 is to mimic smb1 behaviour and offset the index_of_last_entry by 2.

Test results comparing smb1 and smb2 before/after the fix on root share, non-root shares and on large directories (ie. multi-response dir listing):

commit d80771c08363ad7fbf0f56f5301e7ca65065c582 upstream.

When compiling with CONFIG_DEBUG_ATOMIC_SLEEP=y the mxs-dcp driver prints warnings such as:

WARNING: CPU: 0 PID: 120 at kernel/sched/core.c:7736 __might_sleep+0x98/0x9c do not call blocking ops when !TASK_RUNNING; state=1 set at [<8081978c>] dcp_chan_thread_sha+0x3c/0x2ec

The problem is that blocking ops will manipulate current->state themselves so it is not allowed to call them between set_current_state(TASK_INTERRUPTIBLE) and schedule().

Fix this by converting the per-chan mutex to a spinlock (it only protects tiny list ops anyway) and rearranging the wait logic so that callbacks are called current->state as TASK_RUNNING. Those callbacks will indeed call blocking ops themselves so this is required.

In dlm_init_lockres() we access and modify res->tracking and dlm->tracking_list without holding dlm->track_lock. This can cause list corruptions and can end up in kernel panic.

Fix this by locking res->tracking and dlm->tracking_list with dlm->track_lock instead of dlm->spinlock.
