[PATCH OLK-6.6 V1] sched: More flexible use of CPU quota when CPU is idle
by Cheng Yu 06 Aug '25

06 Aug '25

From: Zheng Zucheng <zhengzucheng(a)huawei.com> hulk inclusion category: feature bugzilla: https://gitee.com/openeuler/kernel/issues/ICE7WC -------------------------------- This feature allows users to use CPU quota more flexibly when CPU is idle and it will cause the CPU quota to be exceeded. So, it cannot be used in scenarios where there are strict restrictions on the use of the CPU quota, such as some commercial scenarios that charge based on the use of CPU quota.

[PATCH OLK-6.6] crypto: hisilicon/qm - clear the memory before enabling the device
by Weili Qian 06 Aug '25

06 Aug '25

From: lizhi <lizhi206(a)huawei.com> driver inclusion category: bugfix bugzilla: https://gitee.com/openeuler/kernel/issues/ICRCS6 CVE: NA ---------------------------------------------------------------------- When the driver enables the device, memory will be allocated and configured for the device via the mailbox. As the device executes tasks, it modifies the memory to notify the software of the task status. When the device is re-enabled, the memory must be cleared before being configured for the device again. Otherwise, when the device executes new operations, the software may read incorrect task status from the memory, leading to operational failures. Currently, memory clearing is implemented in the qm_invalid_queues(). However, The qm_invalid_queues() is not called during device suspension and resumption, which results in operational failures after resuming. To address this issue, the memory clearing process should be moved to the hisi_qm_start().

[PATCH OLK-6.6 v2] posix-cpu-timers: fix race between handle_posix_cpu_timers() and posix_cpu_timer_del()
by Xiongfeng Wang 06 Aug '25

06 Aug '25

From: Oleg Nesterov <oleg(a)redhat.com> stable inclusion from stable-v6.6.94 commit 2c72fe18cc5f9f1750f5bc148cf1c94c29e106ff category: bugfix bugzilla: https://gitee.com/src-openeuler/kernel/issues/ICO1SY CVE: CVE-2025-38352 Reference: https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/commit/?id… -------------------------------- commit f90fff1e152dedf52b932240ebbd670d83330eca upstream. If an exiting non-autoreaping task has already passed exit_notify() and calls handle_posix_cpu_timers() from IRQ, it can be reaped by its parent or debugger right after unlock_task_sighand(). If a concurrent posix_cpu_timer_del() runs at that moment, it won't be able to detect timer->it.cpu.firing != 0: cpu_timer_task_rcu() and/or lock_task_sighand() will fail. Add the tsk->exit_state check into run_posix_cpu_timers() to fix this. This fix is not needed if CONFIG_POSIX_CPU_TIMERS_TASK_WORK=y, because exit_task_work() is called before exit_notify(). But the check still makes sense, task_work_add(&tsk->posix_cputimers_work.work) will fail anyway in this case.

This results in conf->r1bio_pool.wait.head pointing to a stack address. Accessing this address later can lead to a kernel panic. Example access path: raid1_reshape() { // newpool is on the stack mempool_t newpool, oldpool; // initialize newpool.wait.head to stack address mempool_init(&newpool, ...); conf->r1bio_pool = newpool; } raid1_read_request() or raid1_write_request() { alloc_r1bio() { mempool_alloc() { // if pool->alloc fails remove_element() { --pool->curr_nr; } } } } mempool_free() { if (pool->curr_nr < pool->min_nr) { // pool->wait.head is a stack address // wake_up() will try to access this invalid address // which leads to a kernel panic return; wake_up(&pool->wait); } } Fix: reinit conf->r1bio_pool.wait after assigning newpool.

[PATCH OLK-5.10] blk-mq: don't touch ->tagset in blk_mq_get_sq_hctx

From: Ming Lei <ming.lei(a)redhat.com> mainline inclusion from mainline-v5.19-rc1 commit 5d05426e2d5fd7df8afc866b78c36b37b00188b7 category: bugfix bugzilla: https://gitee.com/src-openeuler/kernel/issues/IBP2VT CVE: CVE-2022-49377 Reference: https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?… -------------------------------- blk_mq_run_hw_queues() could be run when there isn't queued request and after queue is cleaned up, at that time tagset is freed, because tagset lifetime is covered by driver, and often freed after blk_cleanup_queue() returns. So don't touch ->tagset for figuring out current default hctx by the mapping built in request queue, so use-after-free on tagset can be avoided. Meantime this way should be fast than retrieving mapping from tagset.

[PATCH OLK-5.10] posix-cpu-timers: fix race between handle_posix_cpu_timers() and posix_cpu_timer_del()

From: Oleg Nesterov <oleg(a)redhat.com> stable inclusion from stable-v5.10.239 commit c076635b3a42771ace7d276de8dc3bc76ee2ba1b category: bugfix bugzilla: 189268 CVE: CVE-2025-38352 Reference: https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/commit/?id… -------------------------------- commit f90fff1e152dedf52b932240ebbd670d83330eca upstream. If an exiting non-autoreaping task has already passed exit_notify() and calls handle_posix_cpu_timers() from IRQ, it can be reaped by its parent or debugger right after unlock_task_sighand(). If a concurrent posix_cpu_timer_del() runs at that moment, it won't be able to detect timer->it.cpu.firing != 0: cpu_timer_task_rcu() and/or lock_task_sighand() will fail. Add the tsk->exit_state check into run_posix_cpu_timers() to fix this. This fix is not needed if CONFIG_POSIX_CPU_TIMERS_TASK_WORK=y, because exit_task_work() is called before exit_notify(). But the check still makes sense, task_work_add(&tsk->posix_cputimers_work.work) will fail anyway in this case.

[PATCH OLK-6.6] xdp: Reset bpf_redirect_info before running a xdp's BPF prog.
by Wang Liang 05 Aug '25

05 Aug '25

From: Sebastian Andrzej Siewior <bigeasy(a)linutronix.de> stable inclusion from stable-v6.6.88 commit 202bca49b7f9ed3c5f5f7bb00adabea6339efe2d category: bugfix bugzilla: https://gitee.com/src-openeuler/kernel/issues/IC6350 Reference: https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/commit/?id… -------------------------------- Ricardo reported a KASAN discovered use after free in v6.6-stable. The syzbot starts a BPF program via xdp_test_run_batch() which assigns ri->tgt_value via dev_hash_map_redirect() and the return code isn't XDP_REDIRECT it looks like nonsense. So the output in bpf_warn_invalid_xdp_action() appears once. Then the TUN driver runs another BPF program (on the same CPU) which returns XDP_REDIRECT without setting ri->tgt_value first. It invokes bpf_trace_printk() to print four characters and obtain the required return value. This is enough to get xdp_do_redirect() invoked which then accesses the pointer in tgt_value which might have been already deallocated. This problem does not affect upstream because since commit 401cb7dae8130 ("net: Reference bpf_redirect_info via task_struct on PREEMPT_RT.") the per-CPU variable is referenced via task's task_struct and exists on the stack during NAPI callback. Therefore it is cleared once before the first invocation and remains valid within the RCU section of the NAPI callback. Instead of performing the huge backport of the commit (plus its fix ups) here is an alternative version which only resets the variable in question prior invoking the BPF program.

[PATCH OLK-6.6 V1] i2c/designware: Fix an initialization issue
by Wang Tao 05 Aug '25

05 Aug '25

From: "Michael J. Ruhl" <michael.j.ruhl(a)intel.com> stable inclusion from stable-v6.6.97 commit 6358cb9c2a31e23b6b51bfcd7fe2b7becaf6b149 category: bugfix bugzilla: https://gitee.com/src-openeuler/kernel/issues/ICOXE9 CVE: CVE-2025-38380 Reference: https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/commit/?id… -------------------------------- commit 3d30048958e0d43425f6d4e76565e6249fa71050 upstream. The i2c_dw_xfer_init() function requires msgs and msg_write_idx from the dev context to be initialized. amd_i2c_dw_xfer_quirk() inits msgs and msgs_num, but not msg_write_idx. This could allow an out of bounds access (of msgs). Initialize msg_write_idx before calling i2c_dw_xfer_init().

[PATCH -next RFC] irqchip/gic-v5: Improve the SPI alloc efficiency
by Jinjie Ruan 04 Aug '25

04 Aug '25

If the GICv5 system has a large number of PEs and IRS components, traversing the linked list to find the irs_data corresponding to a specific SPI interrupt will be very slow. Since the maximum number of IRS nodes, the minimum and maximum SPI interrupt numbers for each IRS is known during the initialization of the IRS nodes, sort the IRS nodes by interrupt number at the initial stage. This way, when allocating SPI interrupts, we can directly perform a binary search on the irs_data using the SPI interrupt number with O(log N) complexity.

From: Henry Martin <bsdhenrymartin(a)gmail.com> stable inclusion from stable-v6.6.94 commit 8312b1f776f71979bf33bda7acc05b348e8792c7 category: bugfix bugzilla: https://gitee.com/src-openeuler/kernel/issues/ICJT7X CVE: CVE-2025-38145 Reference: https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/commit/?id… -------------------------------- [ Upstream commit f1706e0e1a74b095cbc60375b9b1e6205f5f4c98 ] devm_kasprintf() returns NULL when memory allocation fails.

When early termination occurs due to malicious ACPI table, Linux kernel terminates ACPI function and continues to boot process. While kernel terminates ACPI function, kmem_cache_destroy() reports Acpi-Operand cache leak. Boot log of ACPI operand cache leak is as follows: >[ 0.585957] ACPI: Added _OSI(Module Device) >[ 0.587218] ACPI: Added _OSI(Processor Device) >[ 0.588530] ACPI: Added _OSI(3.0 _SCP Extensions) >[ 0.589790] ACPI: Added _OSI(Processor Aggregator Device) >[ 0.591534] ACPI Error: Illegal I/O port address/length above 64K: C806E00000004002/0x2 (20170303/hwvalid-155) >[ 0.594351] ACPI Exception: AE_LIMIT, Unable to initialize fixed events (20170303/evevent-88) >[ 0.597858] ACPI: Unable to start the ACPI Interpreter >[ 0.599162] ACPI Error: Could not remove SCI handler (20170303/evmisc-281) >[ 0.601836] kmem_cache_destroy Acpi-Operand: Slab cache still has objects >[ 0.603556] CPU: 0 PID: 1 Comm: swapper/0 Not tainted 4.12.0-rc5 #26 >[ 0.605159] Hardware name: innotek gmb_h virtual_box/virtual_box, BIOS virtual_box 12/01/2006 >[ 0.609177] Call Trace: >[ 0.610063] ? dump_stack+0x5c/0x81 >[ 0.611118] ? kmem_cache_destroy+0x1aa/0x1c0 >[ 0.612632] ? acpi_sleep_proc_init+0x27/0x27 >[ 0.613906] ? acpi_os_delete_cache+0xa/0x10 >[ 0.617986] ? acpi_ut_delete_caches+0x3f/0x7b >[ 0.619293] ? acpi_terminate+0xa/0x14 >[ 0.620394] ? acpi_init+0x2af/0x34f >[ 0.621616] ? __class_create+0x4c/0x80 >[ 0.623412] ? video_setup+0x7f/0x7f >[ 0.624585] ? acpi_sleep_proc_init+0x27/0x27 >[ 0.625861] ? do_one_initcall+0x4e/0x1a0 >[ 0.627513] ? kernel_init_freeable+0x19e/0x21f >[ 0.628972] ? rest_init+0x80/0x80 >[ 0.630043] ? kernel_init+0xa/0x100 >[ 0.631084] ? ret_from_fork+0x25/0x30 >[ 0.633343] vgaarb: loaded >[ 0.635036] EDAC MC: Ver: 3.0.0 >[ 0.638601] PCI: Probing PCI hardware >[ 0.639833] PCI host bridge to bus 0000:00 >[ 0.641031] pci_bus 0000:00: root bus resource [io 0x0000-0xffff] > ... Continue to boot and log is omitted ... I analyzed this memory leak in detail and found acpi_ds_obj_stack_pop_and_ delete() function miscalculated the top of the stack. acpi_ds_obj_stack_push() function uses walk_state->operand_index for start position of the top, but acpi_ds_obj_stack_pop_and_delete() function considers index 0 for it. Therefore, this causes acpi operand memory leak. This cache leak causes a security threat because an old kernel (<= 4.9) shows memory locations of kernel functions in stack dump. Some malicious users could use this information to neutralize kernel ASLR. I made a patch to fix ACPI operand cache leak.

[PATCH OLK-5.10] drm/dp_mst: Ensure mst_primary pointer is valid in drm_dp_mst_handle_up_req()
by Yuan Can 04 Aug '25

04 Aug '25

From: Imre Deak <imre.deak(a)intel.com> mainline inclusion from mainline-v6.13-rc2 commit e54b00086f7473dbda1a7d6fc47720ced157c6a8 category: bugfix bugzilla: https://gitee.com/src-openeuler/kernel/issues/IBJCBT CVE: CVE-2024-57798 Reference: https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?… -------------------------------- While receiving an MST up request message from one thread in drm_dp_mst_handle_up_req(), the MST topology could be removed from another thread via drm_dp_mst_topology_mgr_set_mst(false), freeing mst_primary and setting drm_dp_mst_topology_mgr::mst_primary to NULL. This could lead to a NULL deref/use-after-free of mst_primary in drm_dp_mst_handle_up_req(). Avoid the above by holding a reference for mst_primary in drm_dp_mst_handle_up_req() while it's used. v2: Fix kfreeing the request if getting an mst_primary reference fails.

[PATCH OLK-5.10] [Backport] drm/dp_mst: Fix MST sideband message body length check
by Yuan Can 04 Aug '25

04 Aug '25

From: Imre Deak <imre.deak(a)intel.com> stable inclusion from stable-v5.10.233 commit 109f91d8b9335b0f3714ef9920eae5a8b21d56af category: bugfix bugzilla: https://gitee.com/src-openeuler/kernel/issues/IBEAN5 CVE: CVE-2024-56616 Reference: https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/commit/?id… -------------------------------- [ Upstream commit bd2fccac61b40eaf08d9546acc9fef958bfe4763 ] Fix the MST sideband message body length check, which must be at least 1 byte accounting for the message body CRC (aka message data CRC) at the end of the message. This fixes a case where an MST branch device returns a header with a correct header CRC (indicating a correctly received body length), with the body length being incorrectly set to 0. This will later lead to a memory corruption in drm_dp_sideband_append_payload() and the following errors in dmesg: UBSAN: array-index-out-of-bounds in drivers/gpu/drm/display/drm_dp_mst_topology.c:786:25 index -1 is out of range for type 'u8 [48]' Call Trace: drm_dp_sideband_append_payload+0x33d/0x350 [drm_display_helper] drm_dp_get_one_sb_msg+0x3ce/0x5f0 [drm_display_helper] drm_dp_mst_hpd_irq_handle_event+0xc8/0x1580 [drm_display_helper] memcpy: detected field-spanning write (size 18446744073709551615) of single field "&msg->msg[msg->curlen]" at drivers/gpu/drm/display/drm_dp_mst_topology.c:791 (size 256) Call Trace: drm_dp_sideband_append_payload+0x324/0x350 [drm_display_helper] drm_dp_get_one_sb_msg+0x3ce/0x5f0 [drm_display_helper] drm_dp_mst_hpd_irq_handle_event+0xc8/0x1580 [drm_display_helper] Cc: <stable(a)vger.kernel.org> Cc: Lyude Paul <lyude(a)redhat.com> Reviewed-by: Lyude Paul <lyude(a)redhat.com> Signed-off-by: Imre Deak <imre.deak(a)intel.com> Link: https://patchwork.freedesktop.org/patch/msgid/20241125205314.1725887-1-imre… Signed-off-by: Sasha Levin <sashal(a)kernel.org> Signed-off-by: Yuan Can <yuancan(a)huawei.com> --- drivers/gpu/drm/drm_dp_mst_topology.c | 3 +++ 1 file changed, 3 insertions(+) diff --git a/drivers/gpu/drm/drm_dp_mst_topology.c b/drivers/gpu/drm/drm_dp_mst_topology.c index bb9f2342e96b..e53306ffeb63 100644 --- a/drivers/gpu/drm/drm_dp_mst_topology.c +++ b/drivers/gpu/drm/drm_dp_mst_topology.c @@ -318,6 +318,9 @@ static bool drm_dp_decode_sideband_msg_hdr(struct drm_dp_sideband_msg_hdr *hdr, hdr->broadcast = (buf[idx] >> 7) & 0x1; hdr->path_msg = (buf[idx] >> 6) & 0x1; hdr->msg_len = buf[idx] & 0x3f; + if (hdr->msg_len < 1) /* min space for body CRC */ + return false; + idx++; hdr->somt = (buf[idx] >> 7) & 0x1; hdr->eomt = (buf[idx] >> 6) & 0x1; -- 2.22.0

[PATCH OLK-6.6] fscrypt: Don't use problematic non-inline crypto engines
by Yongjian Sun 04 Aug '25

04 Aug '25

From: Eric Biggers <ebiggers(a)kernel.org> mainline inclusion from mainline-v6.16-rc7 commit b41c1d8d07906786c60893980d52688f31d114a6 category: bugfix bugzilla: https://gitee.com/src-openeuler/kernel/issues/ICQ8LW Reference: https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?… -------------------------------- Make fscrypt no longer use Crypto API drivers for non-inline crypto engines, even when the Crypto API prioritizes them over CPU-based code (which unfortunately it often does). These drivers tend to be really problematic, especially for fscrypt's workload. This commit has no effect on inline crypto engines, which are different and do work well. Specifically, exclude drivers that have CRYPTO_ALG_KERN_DRIVER_ONLY or CRYPTO_ALG_ALLOCATES_MEMORY set. (Later, CRYPTO_ALG_ASYNC should be excluded too. That's omitted for now to keep this commit backportable, since until recently some CPU-based code had CRYPTO_ALG_ASYNC set.) There are two major issues with these drivers: bugs and performance. First, these drivers tend to be buggy. They're fundamentally much more error-prone and harder to test than the CPU-based code. They often don't get tested before kernel releases, and even if they do, the crypto self-tests don't properly test these drivers. Released drivers have en/decrypted or hashed data incorrectly. These bugs cause issues for fscrypt users who often didn't even want to use these drivers, e.g.: - https://github.com/google/fscryptctl/issues/32 - https://github.com/google/fscryptctl/issues/9 - https://lore.kernel.org/r/PH0PR02MB731916ECDB6C613665863B6CFFAA2@PH0PR02MB7… These drivers have also similarly caused issues for dm-crypt users, including data corruption and deadlocks. Since Linux v5.10, dm-crypt has disabled most of them by excluding CRYPTO_ALG_ALLOCATES_MEMORY. Second, these drivers tend to be *much* slower than the CPU-based code. This may seem counterintuitive, but benchmarks clearly show it. There's a *lot* of overhead associated with going to a hardware driver, off the CPU, and back again. To prove this, I gathered as many systems with this type of crypto engine as I could, and I measured synchronous encryption of 4096-byte messages (which matches fscrypt's workload): Intel Emerald Rapids server: AES-256-XTS: xts-aes-vaes-avx512 16171 MB/s [CPU-based, Vector AES] qat_aes_xts 289 MB/s [Offload, Intel QuickAssist] Qualcomm SM8650 HDK: AES-256-XTS: xts-aes-ce 4301 MB/s [CPU-based, ARMv8 Crypto Extensions] xts-aes-qce 73 MB/s [Offload, Qualcomm Crypto Engine] i.MX 8M Nano LPDDR4 EVK: AES-256-XTS: xts-aes-ce 647 MB/s [CPU-based, ARMv8 Crypto Extensions] xts(ecb-aes-caam) 20 MB/s [Offload, CAAM] AES-128-CBC-ESSIV: essiv(cbc-aes-caam,sha256-lib) 23 MB/s [Offload, CAAM] STM32MP157F-DK2: AES-256-XTS: xts-aes-neonbs 13.2 MB/s [CPU-based, ARM NEON] xts(stm32-ecb-aes) 3.1 MB/s [Offload, STM32 crypto engine] AES-128-CBC-ESSIV: essiv(cbc-aes-neonbs,sha256-lib) 14.7 MB/s [CPU-based, ARM NEON] essiv(stm32-cbc-aes,sha256-lib) 3.2 MB/s [Offload, STM32 crypto engine] Adiantum: adiantum(xchacha12-arm,aes-arm,nhpoly1305-neon) 52.8 MB/s [CPU-based, ARM scalar + NEON] So, there was no case in which the crypto engine was even *close* to being faster. On the first three, which have AES instructions in the CPU, the CPU was 30 to 55 times faster (!). Even on STM32MP157F-DK2 which has a Cortex-A7 CPU that doesn't have AES instructions, AES was over 4 times faster on the CPU. And Adiantum encryption, which is what actually should be used on CPUs like that, was over 17 times faster. Other justifications that have been given for these non-inline crypto engines (almost always coming from the hardware vendors, not actual users) don't seem very plausible either: - The crypto engine throughput could be improved by processing multiple requests concurrently. Currently irrelevant to fscrypt, since it doesn't do that. This would also be complex, and unhelpful in many cases. 2 of the 4 engines I tested even had only one queue. - Some of the engines, e.g. STM32, support hardware keys. Also currently irrelevant to fscrypt, since it doesn't support these. Interestingly, the STM32 driver itself doesn't support this either. - Free up CPU for other tasks and/or reduce energy usage. Not very plausible considering the "short" message length, driver overhead, and scheduling overhead. There's just very little time for the CPU to do something else like run another task or enter low-power state, before the message finishes and it's time to process the next one. - Some of these engines resist power analysis and electromagnetic attacks, while the CPU-based crypto generally does not. In theory, this sounds great. In practice, if this benefit requires the use of an off-CPU offload that massively regresses performance and has a low-quality, buggy driver, the price for this hardening (which is not relevant to most fscrypt users, and tends to be incomplete) is just too high. Inline crypto engines are much more promising here, as are on-CPU solutions like RISC-V High Assurance Cryptography.

[PATCH OLK-6.6] Squashfs: check return result of sb_min_blocksize
by Long Li 04 Aug '25

04 Aug '25

From: Phillip Lougher <phillip(a)squashfs.org.uk> mainline inclusion from mainline-v6.15-rc6 commit 734aa85390ea693bb7eaf2240623d41b03705c84 category: bugfix bugzilla: https://gitee.com/src-openeuler/kernel/issues/ICOXJK CVE: CVE-2025-38415 Reference: https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?… -------------------------------- Syzkaller reports an "UBSAN: shift-out-of-bounds in squashfs_bio_read" bug. Syzkaller forks multiple processes which after mounting the Squashfs filesystem, issues an ioctl("/dev/loop0", LOOP_SET_BLOCK_SIZE, 0x8000). Now if this ioctl occurs at the same time another process is in the process of mounting a Squashfs filesystem on /dev/loop0, the failure occurs. When this happens the following code in squashfs_fill_super() fails. ---- msblk->devblksize = sb_min_blocksize(sb, SQUASHFS_DEVBLK_SIZE); msblk->devblksize_log2 = ffz(~msblk->devblksize); ---- sb_min_blocksize() returns 0, which means msblk->devblksize is set to 0. As a result, ffz(~msblk->devblksize) returns 64, and msblk->devblksize_log2 is set to 64. This subsequently causes the UBSAN: shift-out-of-bounds in fs/squashfs/block.c:195:36 shift exponent 64 is too large for 64-bit type 'u64' (aka 'unsigned long long') This commit adds a check for a 0 return by sb_min_blocksize().

[PATCH OLK-5.10] selftests/tracing: Fix false failure of subsystem event test
by Tengda Wu 04 Aug '25

04 Aug '25

From: Steven Rostedt <rostedt(a)goodmis.org> mainline inclusion from mainline-v6.17 commit 213879061a9c60200ba971330dbefec6df3b4a30 category: bugfix bugzilla: https://gitee.com/openeuler/kernel/issues/ICQQ5K Reference: https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?… -------------------------------- The subsystem event test enables all "sched" events and makes sure there's at least 3 different events in the output. It used to cat the entire trace file to | wc -l, but on slow machines, that could last a very long time. To solve that, it was changed to just read the first 100 lines of the trace file. This can cause false failures as some events repeat so often, that the 100 lines that are examined could possibly be of only one event. Instead, create an awk script that looks for 3 different events and will exit out after it finds them. This will find the 3 events the test looks for (eventually if it works), and still exit out after the test is satisfied and not cause slower machines to run forever.
