[PATCH RESEND] EDAC/altera: Fix possible null pointer dereference

by Ma Ke

In altr_s10_sdram_check_ecc_deps(), of_get_address() may return NULL which is later dereferenced. Fix this bug by adding NULL check.

[PATCH net v3] net: usb: sr9700: fix uninitialized variable use in sr_mdio_read

by Ma Ke

It could lead to error happen because the variable res is not updated if the call to sr_share_read_word returns an error. In this particular case error code was returned and res stayed uninitialized. This can be avoided by checking the return value of sr_share_read_word and propagating the error if the read operation failed. Found by code review.

[PATCH] mm: fix maxnode for mbind(), set_mempolicy() and migrate_pages()

by Jerome Glisse

Because maxnode bug there is no way to bind or migrate_pages to the last node in multi-node NUMA system unless you lie about maxnodes when making the mbind, set_mempolicy or migrate_pages syscall. Manpage for those syscall describe maxnodes as the number of bits in the node bitmap ("bit mask of nodes containing up to maxnode bits"). Thus if maxnode is n then we expect to have a n bit(s) bitmap which means that the mask of valid bits is ((1 << n) - 1). The get_nodes() decrement lead to the mask being ((1 << (n - 1)) - 1). The three syscalls use a common helper get_nodes() and first things this helper do is decrement maxnode by 1 which leads to using n-1 bits in the provided mask of nodes (see get_bitmap() an helper function to get_nodes()). The lead to two bugs, either the last node in the bitmap provided will not be use in either of the three syscalls, or the syscalls will error out and return EINVAL if the only bit set in the bitmap was the last bit in the mask of nodes (which is ignored because of the bug and an empty mask of nodes is an invalid argument). I am surprised this bug was never caught ... it has been in the kernel since forever. People can use the following function to detect if the kernel has the bug: bool kernel_has_maxnodes_bug(void) { unsigned long nodemask = 1; bool has_bug; long res; res = set_mempolicy(MPOL_BIND, &nodemask, 1); has_bug = res && (errno == EINVAL); set_mempolicy(MPOL_DEFAULT, NULL, 0); return has_bug; } You can tested with any of the three program below: gcc mbind.c -o mbind -lnuma gcc set_mempolicy.c -o set_mempolicy -lnuma gcc migrate_pages.c -o migrate_pages -lnuma First argument is maxnode, second argument is the bit index to set in the mask of node (0 set the first bit, 1 the second bit, ...). ./mbind 2 1 & sleep 2 && numastat -n -p `pidof mbind` && fg ./set_mempolicy 2 1 & sleep 2 && numastat -n -p `pidof set_mempolicy` && fg ./migrate_pages 2 1 & sleep 2 && numastat -n -p `pidof migrate_pages` && fg mbind.c %< ---------------------------------------------------------- void *anon_mem(size_t size) { void *ret; ret = mmap(NULL, size, PROT_READ| PROT_WRITE, MAP_PRIVATE| MAP_ANON, -1, 0); return ret == MAP_FAILED ?

Its filename is crash-fix-x86_32-crash-memory-reserve-dead-loop-bug-at-high.patch This patch will shortly appear at https://git.kernel.org/pub/scm/linux/kernel/git/akpm/25-new.git/tree/patche… This patch will later appear in the mm-nonmm-unstable branch at git://git.kernel.org/pub/scm/linux/kernel/git/akpm/mm Before you just go and hit "reply", please: a) Consider who else should be cc'ed b) Prefer to cc a suitable mailing list as well c) Ideally: find the original patch on the mailing list and do a reply-to-all to that, adding suitable additional cc's *** Remember to use Documentation/process/submit-checklist.rst when testing your code *** The -mm tree is included into linux-next via the mm-everything branch at git://git.kernel.org/pub/scm/linux/kernel/git/akpm/mm and is updated there every 2-3 working days ------------------------------------------------------ From: Jinjie Ruan <ruanjinjie(a)huawei.com> Subject: crash: fix x86_32 crash memory reserve dead loop bug at high Date: Thu, 18 Jul 2024 11:54:43 +0800 On x86_32 Qemu machine with 1GB memory, the cmdline "crashkernel=512M" will also cause system stall as below: ACPI: Reserving FACP table memory at [mem 0x3ffe18b8-0x3ffe192b] ACPI: Reserving DSDT table memory at [mem 0x3ffe0040-0x3ffe18b7] ACPI: Reserving FACS table memory at [mem 0x3ffe0000-0x3ffe003f] ACPI: Reserving APIC table memory at [mem 0x3ffe192c-0x3ffe19bb] ACPI: Reserving HPET table memory at [mem 0x3ffe19bc-0x3ffe19f3] ACPI: Reserving WAET table memory at [mem 0x3ffe19f4-0x3ffe1a1b] 143MB HIGHMEM available. 879MB LOWMEM available. mapped low ram: 0 - 36ffe000 low ram: 0 - 36ffe000 (stall here) The reason is that the CRASH_ADDR_LOW_MAX is equal to CRASH_ADDR_HIGH_MAX on x86_32, the first "low" crash kernel memory reservation for 512M fails, then it go into the "retry" loop and never came out as below (consider CRASH_ADDR_LOW_MAX = CRASH_ADDR_HIGH_MAX = 512M): -> reserve_crashkernel_generic() and high is false -> alloc at [0, 0x20000000] fail -> alloc at [0x20000000, 0x20000000] fail and repeatedly (because CRASH_ADDR_LOW_MAX = CRASH_ADDR_HIGH_MAX). Fix it by skipping meaningless calls of memblock_phys_alloc_range() with `start = end` After this patch, the retry dead loop is avoided and print below info: cannot allocate crashkernel (size:0x20000000) And apply generic crashkernel reservation to 32bit system will be ready.

[PATCH v2 4.19 0/4] ext4: improve delalloc buffer write performance

by WangYuli

Changes since v1: Fixed some formatting errors to make the patchset less confusing. A patchset from linux-5.15 should be backported to 4.19 that can significantly improve ext4 fs read and write performance.

Its filename is mm-page_alloc-fix-pcp-count-race-between-drain_pages_zone-vs-__rmqueue_pcplist.patch This patch will shortly appear at https://git.kernel.org/pub/scm/linux/kernel/git/akpm/25-new.git/tree/patche… This patch will later appear in the mm-hotfixes-unstable branch at git://git.kernel.org/pub/scm/linux/kernel/git/akpm/mm Before you just go and hit "reply", please: a) Consider who else should be cc'ed b) Prefer to cc a suitable mailing list as well c) Ideally: find the original patch on the mailing list and do a reply-to-all to that, adding suitable additional cc's *** Remember to use Documentation/process/submit-checklist.rst when testing your code *** The -mm tree is included into linux-next via the mm-everything branch at git://git.kernel.org/pub/scm/linux/kernel/git/akpm/mm and is updated there every 2-3 working days ------------------------------------------------------ From: Li Zhijian <lizhijian(a)fujitsu.com> Subject: mm/page_alloc: fix pcp->count race between drain_pages_zone() vs __rmqueue_pcplist() Date: Tue, 23 Jul 2024 14:44:28 +0800 It's expected that no page should be left in pcp_list after calling zone_pcp_disable() in offline_pages(). Previously, it's observed that offline_pages() gets stuck [1] due to some pages remaining in pcp_list. Cause: There is a race condition between drain_pages_zone() and __rmqueue_pcplist() involving the pcp->count variable. See below scenario: CPU0 CPU1 ---------------- --------------- spin_lock(&pcp->lock); __rmqueue_pcplist() { zone_pcp_disable() { /* list is empty */ if (list_empty(list)) { /* add pages to pcp_list */ alloced = rmqueue_bulk() mutex_lock(&pcp_batch_high_lock) ... __drain_all_pages() { drain_pages_zone() { /* read pcp->count, it's 0 here */ count = READ_ONCE(pcp->count) /* 0 means nothing to drain */ /* update pcp->count */ pcp->count += alloced << order; ... ... spin_unlock(&pcp->lock); In this case, after calling zone_pcp_disable() though, there are still some pages in pcp_list. And these pages in pcp_list are neither movable nor isolated, offline_pages() gets stuck as a result. Solution: Expand the scope of the pcp->lock to also protect pcp->count in drain_pages_zone(), to ensure no pages are left in the pcp list after zone_pcp_disable() [1] https://lore.kernel.org/linux-mm/6a07125f-e720-404c-b2f9-e55f3f166e85@fujit… Link: https://lkml.kernel.org/r/20240723064428.1179519-1-lizhijian@fujitsu.com Fixes: 4b23a68f9536 ("mm/page_alloc: protect PCP lists with a spinlock") Signed-off-by: Li Zhijian <lizhijian(a)fujitsu.com> Reported-by: Yao Xingtao <yaoxt.fnst(a)fujitsu.com> Reviewed-by: Vlastimil Babka <vbabka(a)suse.cz> Cc: David Hildenbrand <david(a)redhat.com> Cc: <stable(a)vger.kernel.org> Signed-off-by: Andrew Morton <akpm(a)linux-foundation.org> --- mm/page_alloc.c | 18 +++++++++++------- 1 file changed, 11 insertions(+), 7 deletions(-) --- a/mm/page_alloc.c~mm-page_alloc-fix-pcp-count-race-between-drain_pages_zone-vs-__rmqueue_pcplist +++ a/mm/page_alloc.c @@ -2343,16 +2343,20 @@ void drain_zone_pages(struct zone *zone, static void drain_pages_zone(unsigned int cpu, struct zone *zone) { struct per_cpu_pages *pcp = per_cpu_ptr(zone->per_cpu_pageset, cpu); - int count = READ_ONCE(pcp->count); - - while (count) { - int to_drain = min(count, pcp->batch << CONFIG_PCP_BATCH_SCALE_MAX); - count -= to_drain; + int count; + do { spin_lock(&pcp->lock); - free_pcppages_bulk(zone, to_drain, pcp, 0); + count = pcp->count; + if (count) { + int to_drain = min(count, + pcp->batch << CONFIG_PCP_BATCH_SCALE_MAX); + + free_pcppages_bulk(zone, to_drain, pcp, 0); + count -= to_drain; + } spin_unlock(&pcp->lock); - } + } while (count); } /* _ Patches currently in -mm which might be from lizhijian(a)fujitsu.com are mm-page_alloc-fix-pcp-count-race-between-drain_pages_zone-vs-__rmqueue_pcplist.patch
