[merged mm-stable] mm-hugetlb-pass-correct-order_per_bit-to-cma_declare_contiguous_nid.patch removed from -mm tree

The quilt patch titled Subject: mm/hugetlb: pass correct order_per_bit to cma_declare_contiguous_nid has been removed from the -mm tree. Its filename was mm-hugetlb-pass-correct-order_per_bit-to-cma_declare_contiguous_nid.patch This patch was dropped because it was merged into the mm-stable branch of git://git.kernel.org/pub/scm/linux/kernel/git/akpm/mm ------------------------------------------------------ From: Frank van der Linden <fvdl(a)google.com> Subject: mm/hugetlb: pass correct order_per_bit to cma_declare_contiguous_nid Date: Thu, 4 Apr 2024 16:25:15 +0000 The hugetlb_cma code passes 0 in the order_per_bit argument to cma_declare_contiguous_nid (the alignment, computed using the page order, is correctly passed in). This causes a bit in the cma allocation bitmap to always represent a 4k page, making the bitmaps potentially very large, and slower. It would create bitmaps that would be pretty big. E.g. for a 4k page size on x86, hugetlb_cma=64G would mean a bitmap size of (64G / 4k) / 8 == 2M. With HUGETLB_PAGE_ORDER as order_per_bit, as intended, this would be (64G / 2M) / 8 == 4k. So, that's quite a difference. Also, this restricted the hugetlb_cma area to ((PAGE_SIZE << MAX_PAGE_ORDER) * 8) * PAGE_SIZE (e.g. 128G on x86) , since bitmap_alloc uses normal page allocation, and is thus restricted by MAX_PAGE_ORDER. Specifying anything about that would fail the CMA initialization. So, correctly pass in the order instead.

However, this is too strict, as this will fail if order_per_bit > pageblock_order, which is a valid configuration. We could check IS_ALIGNED both ways, but since both numbers are powers of two, no check is needed at all.

[PATCH v5.10 v5.15] net/mlx5e: Fix a race in command alloc flow

by Samasth Norway Ananda

From: Shifeng Li <lishifeng(a)sangfor.com.cn> [ Upstream commit 8f5100da56b3980276234e812ce98d8f075194cd ] Fix a cmd->ent use after free due to a race on command entry. Such race occurs when one of the commands releases its last refcount and frees its index and entry while another process running command flush flow takes refcount to this command entry. The process which handles commands flush may see this command as needed to be flushed if the other process allocated a ent->idx but didn't set ent to cmd->ent_arr in cmd_work_handler(). Fix it by moving the assignment of cmd->ent_arr into the spin lock.

[PATCH 3/3] net: bcmgenet: synchronize UMAC_CMD access

by Doug Berger

The UMAC_CMD register is written from different execution contexts and has insufficient synchronization protections to prevent possible corruption. Of particular concern are the acceses from the phy_device delayed work context used by the adjust_link call and the BH context that may be used by the ndo_set_rx_mode call. A spinlock is added to the driver to protect contended register accesses (i.e. reg_lock) and it is used to synchronize accesses to UMAC_CMD.

[PATCH 2/3] net: bcmgenet: synchronize use of bcmgenet_set_rx_mode()

by Doug Berger

The ndo_set_rx_mode function is synchronized with the netif_addr_lock spinlock and BHs disabled. Since this function is also invoked directly from the driver the same synchronization should be applied.

[PATCH 1/3] net: bcmgenet: synchronize EXT_RGMII_OOB_CTRL access

by Doug Berger

The EXT_RGMII_OOB_CTRL register can be written from different contexts. It is predominantly written from the adjust_link handler which is synchronized by the phydev->lock, but can also be written from a different context when configuring the mii in bcmgenet_mii_config(). The chances of contention are quite low, but it is conceivable that adjust_link could occur during resume when WoL is enabled so use the phydev->lock synchronizer in bcmgenet_mii_config() to be sure.

The patch titled Subject: kmsan: compiler_types: declare __no_sanitize_or_inline has been added to the -mm mm-hotfixes-unstable branch.
