[PATCH] bcache: set max writeback rate when I/O request is idle

by Coly Li

Commit b1092c9af9ed ("bcache: allow quick writeback when backing idle") allows the writeback rate to be faster if there is no I/O request on a bcache device. It works well if there is only one bcache device attached to the cache set. If there are many bcache devices attached to a cache set, it may introduce performance regression because multiple faster writeback threads of the idle bcache devices will compete the btree level locks with the bcache device who have I/O requests coming. This patch fixes the above issue by only permitting fast writebac when all bcache devices attached on the cache set are idle. And if one of the bcache devices has new I/O request coming, minimized all writeback throughput immediately and let PI controller __update_writeback_rate() to decide the upcoming writeback rate for each bcache device. Also when all bcache devices are idle, limited wrieback rate to a small number is wast of thoughput, especially when backing devices are slower non-rotation devices (e.g. SATA SSD). This patch sets a max writeback rate for each backing device if the whole cache set is idle. A faster writeback rate in idle time means new I/Os may have more available space for dirty data, and people may observe a better write performance then. Please note bcache may change its cache mode in run time, and this patch still works if the cache mode is switched from writeback mode and there is still dirty data on cache.

Linux 4.17.9

by Greg KH

I'm announcing the release of the 4.17.9 kernel. All users of the 4.17 kernel series must upgrade.

[PATCH net] bonding: set default miimon value for non-arp modes if not set

by Jarod Wilson

For some time now, if you load the bonding driver and configure bond parameters via sysfs using minimal config options, such as specifying nothing but the mode, relying on defaults for everything else, modes that cannot use arp monitoring (802.3ad, balance-tlb, balance-alb) all wind up with both arp_interval=0 (as it should be) and miimon=0, which means the miimon monitor thread never actually runs. This is particularly problematic for 802.3ad. For example, from an LNST recipe I've set up: $ modprobe bonding max_bonds=0" $ echo "+t_bond0" > /sys/class/net/bonding_masters" $ ip link set t_bond0 down" $ echo "802.3ad" > /sys/class/net/t_bond0/bonding/mode" $ ip link set ens1f1 down" $ echo "+ens1f1" > /sys/class/net/t_bond0/bonding/slaves" $ ip link set ens1f0 down" $ echo "+ens1f0" > /sys/class/net/t_bond0/bonding/slaves" $ ethtool -i t_bond0" $ ip link set ens1f1 up" $ ip link set ens1f0 up" $ ip link set t_bond0 up" $ ip addr add 192.168.9.1/24 dev t_bond0" $ ip addr add 2002::1/64 dev t_bond0" This bond comes up okay, but things look slightly suspect in /proc/net/bonding/t_bond0 output: $ grep -i mii /proc/net/bonding/t_bond0 MII Status: up MII Polling Interval (ms): 0 MII Status: up MII Status: up Now, pull a cable on one of the ports in the bond, then reconnect it, and you'll see: Slave Interface: ens1f0 MII Status: down Speed: 1000 Mbps Duplex: full I believe this became a major issue as of commit 4d2c0cda0744, which for 802.3ad bonds, sets slave->link = BOND_LINK_DOWN, with a comment about relying on link monitoring via miimon to set it correctly, but since the miimon work queue never runs, the link just stays marked down. If we simply tweak bond_option_mode_set() slightly, we can check for the non-arp modes having no miimon value set, and insert BOND_DEFAULT_MIIMON, which gets things back in full working order. This problem exists as far back as 4.14, and might be worth fixing in all stable trees since, though the work-around is to simply specify an miimon value yourself.

[patch 6/6] mm: memcg: fix use after free in mem_cgroup_iter()

by akpm＠linux-foundation.org

From: Jing Xia <jing.xia.mail(a)gmail.com> Subject: mm: memcg: fix use after free in mem_cgroup_iter() It was reported that a kernel crash happened in mem_cgroup_iter(), which can be triggered if the legacy cgroup-v1 non-hierarchical mode is used. Unable to handle kernel paging request at virtual address 6b6b6b6b6b6b8f ...... Call trace: mem_cgroup_iter+0x2e0/0x6d4 shrink_zone+0x8c/0x324 balance_pgdat+0x450/0x640 kswapd+0x130/0x4b8 kthread+0xe8/0xfc ret_from_fork+0x10/0x20 mem_cgroup_iter(): ...... if (css_tryget(css)) <-- crash here break; ...... The crashing reason is that mem_cgroup_iter() uses the memcg object whose pointer is stored in iter->position, which has been freed before and filled with POISON_FREE(0x6b). And the root cause of the use-after-free issue is that invalidate_reclaim_iterators() fails to reset the value of iter->position to NULL when the css of the memcg is released in non- hierarchical mode.

[patch 5/6] mm/huge_memory.c: fix data loss when splitting a file pmd

by akpm＠linux-foundation.org

From: Hugh Dickins <hughd(a)google.com> Subject: mm/huge_memory.c: fix data loss when splitting a file pmd __split_huge_pmd_locked() must check if the cleared huge pmd was dirty, and propagate that to PageDirty: otherwise, data may be lost when a huge tmpfs page is modified then split then reclaimed. How has this taken so long to be noticed? Because there was no problem when the huge page is written by a write system call (shmem_write_end() calls set_page_dirty()), nor when the page is allocated for a write fault (fault_dirty_shared_page() calls set_page_dirty()); but when allocated for a read fault (which MAP_POPULATE simulates), no set_page_dirty().

[patch 4/6] fat: fix memory allocation failure handling of match_strdup()

From: OGAWA Hirofumi <hirofumi(a)mail.parknet.co.jp> Subject: fat: fix memory allocation failure handling of match_strdup() In parse_options(), if match_strdup() failed, parse_options() leaves opts->iocharset in unexpected state (i.e. still pointing the freed string). And this can be the cause of double free. To fix, this initialize opts->iocharset always when freeing.

[PATCHv3 1/2] libnvdimm: Use max contiguous area for namespace size

by Keith Busch

This patch will find the max contiguous area to determine the largest pmem namespace size that can be created. If the requested size exceeds the largest available, ENOSPC error will be returned. This fixes the allocation underrun error and wrong error return code that have otherwise been observed as the following kernel warning: WARNING: CPU: <CPU> PID: <PID> at drivers/nvdimm/namespace_devs.c:913 size_store Fixes: a1f3e4d6a0c3 ("libnvdimm, region: update nd_region_available_dpa() for multi-pmem support") Cc: <stable(a)vger.kernel.org> Signed-off-by: Keith Busch <keith.busch(a)intel.com> --- v2 -> v3: This one takes block regions into account by reserving pmem regions on dimms and finding the largest intersection among all dimms in the region. drivers/nvdimm/dimm_devs.c | 30 ++++++++++++++++++++++++++++++ drivers/nvdimm/namespace_devs.c | 6 +++--- drivers/nvdimm/nd-core.h | 9 +++++++++ drivers/nvdimm/region_devs.c | 24 ++++++++++++++++++++++++ 4 files changed, 66 insertions(+), 3 deletions(-) diff --git a/drivers/nvdimm/dimm_devs.c b/drivers/nvdimm/dimm_devs.c index 8d348b22ba45..9e977cbd1a60 100644 --- a/drivers/nvdimm/dimm_devs.c +++ b/drivers/nvdimm/dimm_devs.c @@ -536,6 +536,36 @@ resource_size_t nd_blk_available_dpa(struct nd_region *nd_region) return info.available;
