[PATCH kernel-4.19] memcg: enable accounting of ipc resources
by Yang Yingliang 14 Sep '21

14 Sep '21

From: Vasily Averin <vvs(a)virtuozzo.com> mainline inclusion from mainline-v5.15-rc1 commit 18319498fdd4cdf8c1c2c48cd432863b1f915d6f category: bugfix bugzilla: NA CVE: CVE-2021-3759 --------------------------- When user creates IPC objects it forces kernel to allocate memory for these long-living objects. It makes sense to account them to restrict the host's memory consumption from inside the memcg-limited container. This patch enables accounting for IPC shared memory segments, messages semaphores and semaphore's undo lists.

[PATCH kernel-4.19] Intel: PCI: Add support for Immediate Readiness
by Yang Yingliang 11 Sep '21

11 Sep '21

From: Felipe Balbi <felipe.balbi(a)linux.intel.com> mainline inclusion from mainline-v4.20-rc1 commit d6112f8def514e019658bcc9b57d53acdb71ca3f category: feature bugzilla: https://gitee.com/openeuler/kernel/issues/I47H3V CVE: NA -------------------------------- commit d6112f8def514e019658bcc9b57d53acdb71ca3f upstream. PCIe r4.0, sec 7.5.1.1.4 defines a new bit in the Status Register: Immediate Readiness – This optional bit, when Set, indicates the Function is guaranteed to be ready to successfully complete valid configuration accesses at any time following any reset that the host is capable of issuing Configuration Requests to this Function. When this bit is Set, for accesses to this Function, software is exempt from all requirements to delay configuration accesses following any type of reset, including but not limited to the timing requirements defined in Section 6.6. This means that all delays after a Conventional or Function Reset can be skipped. This patch reads such bit and caches its value in a flag inside struct pci_dev to be checked later if we should delay or can skip delays after a reset. While at that, also move the explicit msleep(100) call from pcie_flr() and pci_af_flr() to pci_dev_wait().

[PATCH kernel-4.19 1/2] nvme-pci: use unsigned for io queue depth
by Yang Yingliang 11 Sep '21

From: Chaitanya Kulkarni <chaitanya.kulkarni(a)wdc.com> mainline inclusion from mainline-5.9-rc1 commit 61f3b89630973037f67d8e25e5d26e80a51a7b37 category: bugfix bugzilla: 175286 CVE: NA --------------------------- The NVMe PCIe declares module parameter io_queue_depth as int. Change this to u16 as queue depth can never be negative. Now to reflect this update module parameter getter function from param_get_int() -> param_get_uint() and respective setter function with type of n changed from int to u16 with param_set_int() to param_set_ushort(). Finally update struct nvme_dev q_depth member to u16 and use u16 in min_t() when calculating dev->q_depth in the nvme_pci_enable() (since q_depth is now u16) and use unsigned int instead of int when calculating dev->tagset.queue_depth as target variable tagset->queue_depth is of type unsigned int in nvme_dev_add().
