Audit_alloc_mark() assign pathname to audit_mark->path, on error path from fsnotify_add_inode_mark(), fsnotify_put_mark will free memory of audit_mark->path, but the caller of audit_alloc_mark will free the pathname again, so there will be double free problem.

Fix this by resetting audit_mark->path to NULL pointer on error path from fsnotify_add_inode_mark().

commit 3dcfb729b5f4a0c9b50742865cd5e6c4dbcc80dc upstream.

With this patch the ARCH= parameter decides if the CONFIG_64BIT option will be set or not. This means, the ARCH= parameter will give:

ARCH=parisc -> 32-bit kernel ARCH=parisc64 -> 64-bit kernel

This simplifies the usage of the other config options like randconfig, allmodconfig and allyesconfig a lot and produces the output which is expected for parisc64 (64-bit) vs. parisc (32-bit).

commit a8faed3a02eeb75857a3b5d660fa80fe79db77a3 upstream.

When CONFIG_ADVISE_SYSCALLS is not set/enabled and CONFIG_COMPAT is set/enabled, the riscv compat_syscall_table references 'compat_sys_fadvise64_64', which is not defined:

riscv64-linux-ld: arch/riscv/kernel/compat_syscall_table.o:(.rodata+0x6f8): undefined reference to `compat_sys_fadvise64_64'

Add 'fadvise64_64' to kernel/sys_ni.c as a conditional COMPAT function so that when CONFIG_ADVISE_SYSCALLS is not set, there is a fallback function available.

commit c2ae7b772ef4e86c5ddf3fd47bf59045ae96a414 upstream

This patch is basically a revert of commit 5a80d1c6a270 ("btrfs: zoned: remove max_zone_append_size logic"), but without unnecessary ASSERT and check. The max_zone_append_size will be used as a hint to estimate the number of extents to cover delalloc/writeback region in the later commits.

The size of a ZONE APPEND bio is also limited by queue_max_segments(), so this commit considers it to calculate max_zone_append_size. Technically, a bio can be larger than queue_max_segments() * PAGE_SIZE if the pages are contiguous. But, it is safe to consider "queue_max_segments() * PAGE_SIZE" as an upper limit of an extent size to calculate the number of extents needed to write data.

If count_max_extents() uses BTRFS_MAX_EXTENT_SIZE to calculate the number of extents needed, btrfs release the metadata reservation too much on its way to write out the data.

Now that BTRFS_MAX_EXTENT_SIZE is replaced with fs_info->max_extent_size, convert count_max_extents() to use it instead, and fix the calculation of the metadata reservation.

[ Upstream commit ff946268a0813c35b790dfbe07c3bfaa7bfb869c ]

Merge i8042 quirk tables to reduce code duplication for devices that need more than one quirk. Before every quirk had its own table with devices needing that quirk. If a new quirk needed to be added a new table had to be created. When a device needed multiple quirks, it appeared in multiple tables. Now only one table called i8042_dmi_quirk_table exists. In it every device has one entry and required quirks are coded in the .driver_data field of the struct dmi_system_id used by this table. Multiple quirks for one device can be applied by bitwise-or of the new SERIO_QUIRK_* defines.

Also align quirkable options with command line parameters and make vendor wide quirks per device overwriteable on a per device basis. The first match is honored while following matches are ignored. So when a vendor wide quirk is defined in the table, a device can inserted before and therefore ignoring the vendor wide define.

A lot of modern Clevo barebones have touchpad and/or keyboard issues after suspend fixable with nomux + reset + noloop + nopnp. Luckily, none of them have an external PS/2 port so this can safely be set for all of them.

I'm not entirely sure if every device listed really needs all four quirks, but after testing and production use. No negative effects could be observed when setting all four.

[ Upstream commit b1f707146923335849fb70237eec27d4d1ae7d62 ]

On some platforms, the current logic of relying on finding new packet solely based on signature pattern can lead to driver reading stale packets. Though this is a bug in those platforms, reduce such exposures by limiting reading packets until the IN pointer.

Two module parameters are introduced:

ql2xrspq_follow_inptr:

When set, on newer adapters that has queue pointer shadowing, look for response packets only until response queue in pointer.

When reset, response packets are read based on a signature pattern logic (old way).

ql2xrspq_follow_inptr_legacy:

Like ql2xrspq_follow_inptr, but for those adapters where there is no queue pointer shadowing.

At btrfs_set_inode_index_count() we refer twice to the number 2 as the initial index value for a directory (when it's empty), with a proper comment explaining the reason for that value. In the next patch I'll have to use that magic value in the directory logging code, so put the value in a #define at btrfs_inode.h, to avoid hardcoding the magic value again at tree-log.c.

In function __extent_writepage() we always pass page start to @delalloc_start for writepage_delalloc().

Thus we don't really need @delalloc_start parameter as we can extract it from @page.

Since commit 5d8544e2d007 ("RISC-V: Generic library routines and assembly") and commit ebcbd75e3962 ("riscv: Fix the bug in memory access fixup code"), if __clear_user and __copy_user return from an fixup branch, CSR_STATUS SR_SUM bit will be set, it is a vulnerability, so that S-mode memory accesses to pages that are accessible by U-mode will success. Disable S-mode access to U-mode memory should clear SR_SUM bit.

When we try to transmit an skb with metadata_dst attached (i.e. dst->dev == NULL) through xfrm interface we can hit a null pointer dereference[1] in xfrmi_xmit2() -> xfrm_lookup_with_ifid() due to the check for a loopback skb device when there's no policy which dereferences dst->dev unconditionally. Not having dst->dev can be interepreted as it not being a loopback device, so just add a check for a null dst_orig->dev.

With this fix xfrm interface's Tx error counters go up as usual.

[ Upstream commit 0c3bc7899e6dfb52df1c46118a5a670ae619645f ]

While looking at our current POSIX ACL handling in the context of some overlayfs work I went through a range of other filesystems checking how they handle them currently and encountered ntfs3.

The posic_acl_{from,to}_xattr() helpers always need to operate on the filesystem idmapping. Since ntfs3 can only be mounted in the initial user namespace the relevant idmapping is init_user_ns.

The posix_acl_{from,to}_xattr() helpers are concerned with translating between the kernel internal struct posix_acl{_entry} and the uapi struct posix_acl_xattr_{header,entry} and the kernel internal data structure is cached filesystem wide.

Additional idmappings such as the caller's idmapping or the mount's idmapping are handled higher up in the VFS. Individual filesystems usually do not need to concern themselves with these.

The posix_acl_valid() helper is concerned with checking whether the values in the kernel internal struct posix_acl can be represented in the filesystem's idmapping. IOW, if they can be written to disk. So this helper too needs to take the filesystem's idmapping.

[ Upstream commit f1e941dbf80a9b8bab0bffbc4cbe41cc7f4c6fb6 ]

When the pn532 uart device is detaching, the pn532_uart_remove() is called. But there are no functions in pn532_uart_remove() that could delete the cmd_timeout timer, which will cause use-after-free bugs. The process is shown below:

(thread 1) | (thread 2) | pn532_uart_send_frame pn532_uart_remove | mod_timer(&pn532->cmd_timeout,...) ... | (wait a time) kfree(pn532) //FREE | pn532_cmd_timeout | pn532_uart_send_frame | pn532->... //USE

This patch adds del_timer_sync() in pn532_uart_remove() in order to prevent the use-after-free bugs. What's more, the pn53x_unregister_nfc() is well synchronized, it sets nfc_dev->shutting_down to true and there are no syscalls could restart the cmd_timeout timer.

Fix the following scenario: 1. ethtool -L $IFACE rx 8 tx 96 2. xdpsock -q 10 -t -z

Above refers to a case where user would like to attach XSK socket in txonly mode at a queue id that does not have a corresponding Rx queue. At this moment ice's XSK logic is tightly bound to act on a "queue pair", e.g. both Tx and Rx queues at a given queue id are disabled/enabled and both of them will get XSK pool assigned, which is broken for the presented queue configuration. This results in the splat included at the bottom, which is basically an OOB access to Rx ring array.

To fix this, allow using the ids only in scope of "combined" queues reported by ethtool. However, logic should be rewritten to allow such configurations later on, which would end up as a complete rewrite of the control path, so let us go with this temporary fix.

The cited commit reintroduced the ability to set hw-tc-offload in switchdev mode by reusing NIC mode calls without modifying it to support both modes, this can cause an illegal memory access when trying to turn hw-tc-offload off.

Fix this by using the right TC_FLAG when checking if tc rules are installed while disabling hw-tc-offload.

[ Upstream commit 6dbe852c379ff032a70a6b13a91914918c82cb07 ]

For some MAC drivers, they set the mac_managed_pm to true in its ->ndo_open() callback. So before the mac_managed_pm is set to true, we still want to leverage the mdio_bus_phy_suspend()/resume() for the phy device suspend and resume. In this case, the phy device is in PHY_READY, and we shouldn't warn about this. It also seems that the check of mac_managed_pm in WARN_ON is redundant since we already check this in the entry of mdio_bus_phy_resume(), so drop it.

This is caused by the global variable ad_ticks_per_sec being zero as demonstrated by the reproducer script discussed below. This causes all timer values in __ad_timer_to_ticks to be zero, resulting in the periodic timer to never fire.

To reproduce: Run the script in `tools/testing/selftests/drivers/net/bonding/bond-break-lacpdu-tx.sh` which puts bonding into a state where it never transmits LACPDUs.

The if check around the contents of bond_3ad_initialize() is no longer needed due to commit 5ee14e6d336f ("bonding: 3ad: apply ad_actor settings changes immediately") which sets ad.system.sys_mac_addr if any one of the bonding parameters whos set function calls bond_3ad_update_ad_actor_settings(). This is because if ad.system.sys_mac_addr is zero it will be set to the current bond mac address, this causes the if check to never be true.

For some reason ebtables rejects blobs that provide entry points that are not supported by the table, but what it should instead reject is the opposite: blobs that DO NOT provide an entry point supported by the table.

t->valid_hooks is the bitmask of hooks (input, forward ...) that will see packets. Providing an entry point that is not support is harmless (never called/used), but the inverse isn't: it results in a crash because the ebtables traverser doesn't expect a NULL blob for a location its receiving packets for.

Instead of fixing all the individual checks, do what iptables is doing and reject all blobs that differ from the expected hooks.

[ Upstream commit 341b6941608762d8235f3fd1e45e4d7114ed8c2c ]

Instead of parsing the data and then validate that type and length are correct, pass a description of the expected data so it can be validated upfront before parsing it to bail out earlier.

This patch adds a new .size field to specify the maximum size of the data area. The .len field is optional and it is used as an input/output field, it provides the specific length of the expected data in the input path. If then .len field is not specified, then obtained length from the netlink attribute is stored. This is required by cmp, bitwise, range and immediate, which provide no netlink attribute that describes the data length. The immediate expression uses the destination register type to infer the expected data type.

Relying on opencoded validation of the expected data might lead to subtle bugs as described in 7e6bc1f6cabc ("netfilter: nf_tables: stricter validation of element data").

[ Upstream commit 9afb4b27349a499483ae0134282cefd0c90f480f ]

To clear the flow table on flow table free, the following sequence normally happens in order:

1) gc_step work is stopped to disable any further stats/del requests. 2) All flow table entries are set to teardown state. 3) Run gc_step which will queue HW del work for each flow table entry. 4) Waiting for the above del work to finish (flush). 5) Run gc_step again, deleting all entries from the flow table. 6) Flow table is freed.

But if a flow table entry already has pending HW stats or HW add work step 3 will not queue HW del work (it will be skipped), step 4 will wait for the pending add/stats to finish, and step 5 will queue HW del work which might execute after freeing of the flow table.

To fix the above, this patch flushes the pending work, then it sets the teardown flag to all flows in the flowtable and it forces a garbage collector run to queue work to remove the flows from hardware, then it flushes this new pending work and (finally) it forces another garbage collector run to remove the entry from the software flowtable.

While reading weight_p, it can be changed concurrently. Thus, we need to add READ_ONCE() to its reader.

Also, dev_[rt]x_weight can be read/written at the same time. So, we need to use READ_ONCE() and WRITE_ONCE() for its access. Moreover, to use the same weight_p while changing dev_[rt]x_weight, we add a mutex in proc_do_dev_weight().

We want to revert the skb TX cache, but MPTCP is currently using it unconditionally.

Rework the MPTCP tx code, so that tcp_tx_skb_cache is not needed anymore: do the whole coalescing check, skb allocation skb initialization/update inside mptcp_sendmsg_frag(), quite alike the current TCP code.

[ Upstream commit 25d7a5f5a6bb15a2dae0a3f39ea5dda215024726 ]

The ixgbe_ptp_start_cyclecounter is intended to be called whenever the cyclecounter parameters need to be changed.

Since commit a9763f3cb54c ("ixgbe: Update PTP to support X550EM_x devices"), this function has cleared the SYSTIME registers and reset the TSAUXC DISABLE_SYSTIME bit.

While these need to be cleared during ixgbe_ptp_reset, it is wrong to clear them during ixgbe_ptp_start_cyclecounter. This function may be called during both reset and link status change. When link changes, the SYSTIME counter is still operating normally, but the cyclecounter should be updated to account for the possibly changed parameters.

Clearing SYSTIME when link changes causes the timecounter to jump because the cycle counter now reads zero.

Extract the SYSTIME initialization out to a new function and call this during ixgbe_ptp_reset. This prevents the timecounter adjustment and avoids an unnecessary reset of the current time.

This also restores the original SYSTIME clearing that occurred during ixgbe_ptp_reset before the commit above.

[ Upstream commit b0f571ecd7943423c25947439045f0d352ca3dbf ]

Fix three bugs in the rxrpc's sendmsg implementation:

(1) rxrpc_new_client_call() should release the socket lock when returning an error from rxrpc_get_call_slot().

(2) rxrpc_wait_for_tx_window_intr() will return without the call mutex held in the event that we're interrupted by a signal whilst waiting for tx space on the socket or relocking the call mutex afterwards.

Fix this by: (a) moving the unlock/lock of the call mutex up to rxrpc_send_data() such that the lock is not held around all of rxrpc_wait_for_tx_window*() and (b) indicating to higher callers whether we're return with the lock dropped. Note that this means recvmsg() will not block on this call whilst we're waiting.

(3) After dropping and regaining the call mutex, rxrpc_send_data() needs to go and recheck the state of the tx_pending buffer and the tx_total_len check in case we raced with another sendmsg() on the same call.

Thinking on this some more, it might make sense to have different locks for sendmsg() and recvmsg(). There's probably no need to make recvmsg() wait for sendmsg(). It does mean that recvmsg() can return MSG_EOR indicating that a call is dead before a sendmsg() to that call returns - but that can currently happen anyway.

Without fix (2), something like the following can be induced:

[ Upstream commit 9cb9dadb8f45c67e4310e002c2f221b70312b293 ]

There is a case found in heavy testing where a link flap happens just before a firmware Recovery event and the driver gets stuck in the BROKEN state. This comes from the driver getting interrupted by a FW generation change when coming back up from the link flap, and the call to ionic_start_queues() in ionic_link_status_check() fails. This can be addressed by having the fw_up code clear the BROKEN bit if seen, rather than waiting for a user to manually force the interface down and then back up.

Assign a random mac address to the VF interface station address if it boots with a zero mac address in order to match similar behavior seen in other VF drivers. Handle the errors where the older firmware does not allow the VF to set its own station address.

Newer firmware will allow the VF to set the station mac address if it hasn't already been set administratively through the PF. Setting it will also be allowed if the VF has trust.

commit 47bf225a8d2cccb15f7e8d4a1ed9b757dd86afd7 upstream.

At btrfs_del_root_ref(), if btrfs_search_slot() returns an error, we end up returning from the function with a value of 0 (success). This happens because the function returns the value stored in the variable 'err', which is 0, while the error value we got from btrfs_search_slot() is stored in the 'ret' variable.

So fix it by setting 'err' with the error value.

commit f2c3bec215694fb8bc0ef5010f2a758d1906fc2d upstream.

If the replace target device reappears after the suspended replace is cancelled, it blocks the mount operation as it can't find the matching replace-item in the metadata. As shown below,

BTRFS error (device sda5): replace devid present without an active replace item

To overcome this situation, the user can run the command

btrfs device scan --forget <replace target device>

and try the mount command again. And also, to avoid repeating the issue, superblock on the devid=0 must be wiped.

wipefs -a device-path-to-devid=0.

This patch adds some info when this situation occurs.

commit 9ea0106a7a3d8116860712e3f17cd52ce99f6707 upstream.

In btrfs_get_dev_args_from_path(), btrfs_get_bdev_and_sb() can fail if the path is invalid. In this case, btrfs_get_dev_args_from_path() returns directly without freeing args->uuid and args->fsid allocated before, which causes memory leak.

To fix these possible leaks, when btrfs_get_bdev_and_sb() fails, btrfs_put_dev_args_from_path() is called to clean up the memory.

commit fc2e426b1161761561624ebd43ce8c8d2fa058da upstream.

When meeting ftrace trampolines in ORC unwinding, unwinder uses address of ftrace_{regs_}call address to find the ORC entry, which gets next frame at sp+176.

If there is an IRQ hitting at sub $0xa8,%rsp, the next frame should be sp+8 instead of 176. It makes unwinder skip correct frame and throw warnings such as "wrong direction" or "can't access registers", etc, depending on the content of the incorrect frame address.

By adding the base address ftrace_{regs_}caller with the offset *ip - ops->trampoline*, we can get the correct address to find the ORC entry.

Also change "caller" to "tramp_addr" to make variable name conform to its content.

[ mingo: Clarified the changelog a bit. ]

commit f87904c075515f3e1d8f4a7115869d3b914674fd upstream.

When a disk is removed, bdi_unregister gets called to stop further writeback and wait for associated delayed work to complete. However, wb_inode_writeback_end() may schedule bandwidth estimation dwork after this has completed, which can result in the timer attempting to access the just freed bdi_writeback.

Fix this by checking if the bdi_writeback is alive, similar to when scheduling writeback work.

Since this requires wb->work_lock, and wb_inode_writeback_end() may get called from interrupt, switch wb->work_lock to an irqsafe lock.

commit d26f60703606ab425eee9882b32a1781a8bed74d upstream.

When user tries to create a DAMON context via the DAMON debugfs interface with a name of an already existing context, the context directory creation fails but a new context is created and added in the internal data structure, due to absence of the directory creation success check. As a result, memory could leak and DAMON cannot be turned on. An example test case is as below:

# cd /sys/kernel/debug/damon/ # echo "off" > monitor_on # echo paddr > target_ids # echo "abc" > mk_context # echo "abc" > mk_context # echo $$ > abc/target_ids # echo "on" > monitor_on <<< fails

Return value of 'debugfs_create_dir()' is expected to be ignored in general, but this is an exceptional case as DAMON feature is depending on the debugfs functionality and it has the potential duplicate name issue. This commit therefore fixes the issue by checking the directory creation failure and immediately return the error in the case.

commit a5a923038d70d2d4a86cb4e3f32625a5ee6e7e24 upstream.

fbcon_do_set_font() calls vc_resize() when font size is changed. However, if if vc_resize() failed, current implementation doesn't revert changes for font size, and this causes inconsistent state.

syzbot reported unable to handle page fault due to this issue [1]. syzbot's repro uses fault injection which cause failure for memory allocation, so vc_resize() failed.

This patch fixes this issue by properly revert changes for font related date when vc_resize() failed.

commit f96f7a40874d7c746680c0b9f57cef2262ae551f upstream.

Patch series "mm/hugetlb: fix write-fault handling for shared mappings", v2.

I observed that hugetlb does not support/expect write-faults in shared mappings that would have to map the R/O-mapped page writable -- and I found two case where we could currently get such faults and would erroneously map an anon page into a shared mapping.

Reproducers part of the patches.

I propose to backport both fixes to stable trees. The first fix needs a small adjustment.

This patch (of 2):

Staring at hugetlb_wp(), one might wonder where all the logic for shared mappings is when stumbling over a write-protected page in a shared mapping. In fact, there is none, and so far we thought we could get away with that because e.g., mprotect() should always do the right thing and map all pages directly writable.

Looks like we were wrong:

-------------------------------------------------------------------------- #include <stdio.h> #include <stdlib.h> #include <string.h> #include <fcntl.h> #include <unistd.h> #include <errno.h> #include <sys/mman.h>

#define HUGETLB_SIZE (2 * 1024 * 1024u)

static void clear_softdirty(void) { int fd = open("/proc/self/clear_refs", O_WRONLY); const char *ctrl = "4"; int ret;

if (fd < 0) { fprintf(stderr, "open(clear_refs) failed\n"); exit(1); } ret = write(fd, ctrl, strlen(ctrl)); if (ret != strlen(ctrl)) { fprintf(stderr, "write(clear_refs) failed\n"); exit(1); } close(fd); }

int main(int argc, char **argv) { char *map; int fd;

fd = open("/dev/hugepages/tmp", O_RDWR | O_CREAT); if (!fd) { fprintf(stderr, "open() failed\n"); return -errno; } if (ftruncate(fd, HUGETLB_SIZE)) { fprintf(stderr, "ftruncate() failed\n"); return -errno; }

map = mmap(NULL, HUGETLB_SIZE, PROT_READ|PROT_WRITE, MAP_SHARED, fd, 0); if (map == MAP_FAILED) { fprintf(stderr, "mmap() failed\n"); return -errno; }

*map = 0;

if (mprotect(map, HUGETLB_SIZE, PROT_READ)) { fprintf(stderr, "mmprotect() failed\n"); return -errno; }

clear_softdirty();

if (mprotect(map, HUGETLB_SIZE, PROT_READ|PROT_WRITE)) { fprintf(stderr, "mmprotect() failed\n"); return -errno; }

*map = 0;

return 0; } --------------------------------------------------------------------------

Above test fails with SIGBUS when there is only a single free hugetlb page. # echo 1 > /sys/kernel/mm/hugepages/hugepages-2048kB/nr_hugepages # ./test Bus error (core dumped)

And worse, with sufficient free hugetlb pages it will map an anonymous page into a shared mapping, for example, messing up accounting during unmap and breaking MAP_SHARED semantics: # echo 2 > /sys/kernel/mm/hugepages/hugepages-2048kB/nr_hugepages # ./test # cat /proc/meminfo | grep HugePages_ HugePages_Total: 2 HugePages_Free: 1 HugePages_Rsvd: 18446744073709551615 HugePages_Surp: 0

Reason in this particular case is that vma_wants_writenotify() will return "true", removing VM_SHARED in vma_set_page_prot() to map pages write-protected. Let's teach vma_wants_writenotify() that hugetlb does not support softdirty tracking.

From the link [1], we can see raid1d was running even after the path

raid_dtr -> md_stop -> __md_stop.

Let's stop write first in destructor to align with normal md-raid to fix the KASAN issue.

Since commit 51f559d66527 ("arm64: Enable repeat tlbi workaround on KRYO4XX gold CPUs"), we failed to detect erratum 1286807 on Cortex-A76 because its entry in arm64_repeat_tlbi_list[] was accidently corrupted by this commit.

Fix this issue by creating a separate entry for Kryo4xx Gold.

commit 65fac0d54f374625b43a9d6ad1f2c212bd41f518 upstream.

Currently, in virtio_scsi, if 'bd->last' is not set to true while dispatching request, such io will stay in driver's queue, and driver will wait for block layer to dispatch more rqs. However, if block layer failed to dispatch more rq, it should trigger commit_rqs to inform driver.

There is a problem in blk_mq_try_issue_list_directly() that commit_rqs won't be called:

// assume that queue_depth is set to 1, list contains two rq blk_mq_try_issue_list_directly blk_mq_request_issue_directly // dispatch first rq // last is false __blk_mq_try_issue_directly blk_mq_get_dispatch_budget // succeed to get first budget __blk_mq_issue_directly scsi_queue_rq cmd->flags |= SCMD_LAST virtscsi_queuecommand kick = (sc->flags & SCMD_LAST) != 0 // kick is false, first rq won't issue to disk queued++

blk_mq_request_issue_directly // dispatch second rq __blk_mq_try_issue_directly blk_mq_get_dispatch_budget // failed to get second budget ret == BLK_STS_RESOURCE blk_mq_request_bypass_insert // errors is still 0

if (!list_empty(list) || errors && ...) // won't pass, commit_rqs won't be called

In this situation, first rq relied on second rq to dispatch, while second rq relied on first rq to complete, thus they will both hung.

Fix the problem by also treat 'BLK_STS_*RESOURCE' as 'errors' since it means that request is not queued successfully.

Same problem exists in blk_mq_dispatch_rq_list(), 'BLK_STS_*RESOURCE' can't be treated as 'errors' here, fix the problem by calling commit_rqs if queue_rq return 'BLK_STS_*RESOURCE'.

commit 11745ecfe8fea4b4a4c322967a7605d2ecbd5080 upstream.

Existing code was generating bogus counts for the SNB IMC bandwidth counters:

$ perf stat -a -I 1000 -e uncore_imc/data_reads/,uncore_imc/data_writes/ 1.000327813 1,024.03 MiB uncore_imc/data_reads/ 1.000327813 20.73 MiB uncore_imc/data_writes/ 2.000580153 261,120.00 MiB uncore_imc/data_reads/ 2.000580153 23.28 MiB uncore_imc/data_writes/

The problem was introduced by commit: 07ce734dd8ad ("perf/x86/intel/uncore: Clean up client IMC")

Where the read_counter callback was replace to point to the generic uncore_mmio_read_counter() function.

The SNB IMC counters are freerunnig 32-bit counters laid out contiguously in MMIO. But uncore_mmio_read_counter() is using a readq() call to read from MMIO therefore reading 64-bit from MMIO. Although this is okay for the uncore_perf_event_update() function because it is shifting the value based on the actual counter width to compute a delta, it is not okay for the uncore_pmu_event_start() which is simply reading the counter and therefore priming the event->prev_count with a bogus value which is responsible for causing bogus deltas in the perf stat command above.

The fix is to reintroduce the custom callback for read_counter for the SNB IMC PMU and use readl() instead of readq(). With the change the output of perf stat is back to normal: $ perf stat -a -I 1000 -e uncore_imc/data_reads/,uncore_imc/data_writes/ 1.000120987 296.94 MiB uncore_imc/data_reads/ 1.000120987 138.42 MiB uncore_imc/data_writes/ 2.000403144 175.91 MiB uncore_imc/data_reads/ 2.000403144 68.50 MiB uncore_imc/data_writes/

commit bf515f024e4c0ca46a1b08c4f31860c01781d8a5 upstream.

If a weak group is broken then the reset_group flag remains set for the next run. Having reset_group set means the counter isn't created and ultimately a segfault.

A simple reproduction of this is:

# perf stat -r2 -e '{cycles,cycles,cycles,cycles,cycles,cycles,cycles,cycles,cycles,cycles}:W

which will be added as a test in the next patch.
