[PATCH] ext4: Fix data corruption caused by unaligned direct AIO

by Lukas Czerner

Ext4 needs to serialize unaligned direct AIO because the zeroing of partial blocks of two competing unaligned AIOs can result in data corruption. However it decides not to serialize if the potentially unaligned aio is past i_size with the rationale that no pending writes are possible past i_size. Unfortunately if the i_size is not block aligned and the second unaligned write lands past i_size, but still into the same block, it has the potential of corrupting the previous unaligned write to the same block. This is (very simplified) reproducer from Frank // 41472 = (10 * 4096) + 512 // 37376 = 41472 - 4096 ftruncate(fd, 41472); io_prep_pwrite(iocbs[0], fd, buf[0], 4096, 37376); io_prep_pwrite(iocbs[1], fd, buf[1], 4096, 41472); io_submit(io_ctx, 1, &iocbs[1]); io_submit(io_ctx, 1, &iocbs[2]); io_getevents(io_ctx, 2, 2, events, NULL); Without this patch the 512B range from 40960 up to the start of the second unaligned write (41472) is going to be zeroed overwriting the data written by the first write. This is a data corruption. 00000000 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 * 00009200 30 30 30 30 30 30 30 30 30 30 30 30 30 30 30 30 * 0000a000 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 * 0000a200 31 31 31 31 31 31 31 31 31 31 31 31 31 31 31 31 With this patch the data corruption is avoided because we will recognize the unaligned_aio and wait for the unwritten extent conversion. 00000000 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 * 00009200 30 30 30 30 30 30 30 30 30 30 30 30 30 30 30 30 * 0000a200 31 31 31 31 31 31 31 31 31 31 31 31 31 31 31 31 * 0000b200 Reported-by: Frank Sorenson <fsorenso(a)redhat.com> Signed-off-by: Lukas Czerner <lczerner(a)redhat.com> Fixes: e9e3bcecf44c ("ext4: serialize unaligned asynchronous DIO") Cc: <stable(a)vger.kernel.org> --- fs/ext4/file.c | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-) diff --git a/fs/ext4/file.c b/fs/ext4/file.c index 69d65d49837b..98ec11f69cd4 100644 --- a/fs/ext4/file.c +++ b/fs/ext4/file.c @@ -125,7 +125,7 @@ ext4_unaligned_aio(struct inode *inode, struct iov_iter *from, loff_t pos) struct super_block *sb = inode->i_sb; int blockmask = sb->s_blocksize - 1; - if (pos >= i_size_read(inode)) + if (pos >= ALIGN(i_size_read(inode), sb->s_blocksize)) return 0; if ((pos | iov_iter_alignment(from)) & blockmask) -- 2.20.1

Perf backport requests for 4.4 and 4.14

by Daniel Díaz

Hello! While trying to add Perf tests to LKFT [1], we encountered some problems building it for two specific combinations: * 4.4 and x86-64 * 4.14 and x86-32 On 4.4, this is what the build failure looks like: | bench/mem-memcpy-x86-64-asm.S:4:10: fatal error: ../../../arch/x86/lib/memcpy_64.S: No such file or directory | #include "../../../arch/x86/lib/memcpy_64.S" | ^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ This was fixed in mainline by commit 7d7d1bf1d1da ("perf bench: Copy kernel files needed to build mem{cpy,set} x86_64 benchmarks"). Instead of just cherry-picking, it requires a proper backport as it needs to copy the existing files in 4.4, not the ones contained in that commit (which are from v4.7-rc5+). On 4.14, this is what the build failure looks like: | In file included from util/libunwind/x86_32.c:33:0: | util/libunwind/../../arch/x86/util/unwind-libunwind.c: In function 'libunwind__x86_reg_id': | util/libunwind/../../arch/x86/util/unwind-libunwind.c:110:11: error: 'EINVAL' undeclared (first use in this function); did you mean 'UNW_EINVAL'? | return -EINVAL; | ^~~~~~ | UNW_EINVAL This was fixed by 44df1afdb174 ("perf tools: Fix compile error with libunwind x86"); it applies cleanly on top of v4.14.106. Thanks and greetings! Daniel Díaz daniel.diaz(a)linaro.org [1] https://lkft.linaro.org/about/

4aa68e07d845 ("KEYS: restrict /proc/keys by credentials at open time")

by Zubin Mithra

Hello, Syzkaller has triggered a kernel BUG when fuzzing a 4.4 kernel with the following stacktrace. Call Trace: [<ffffffff818568d5>] construct_alloc_key security/keys/request_key.c:388 [inline] [<ffffffff818568d5>] construct_key_and_link security/keys/request_key.c:479 [inline] [<ffffffff818568d5>] request_key_and_link+0x49b/0x8c5 security/keys/request_key.c:594 [<ffffffff8184fb08>] SYSC_request_key security/keys/keyctl.c:213 [inline] [<ffffffff8184fb08>] SyS_request_key+0x1ac/0x2a2 security/keys/keyctl.c:158 [<ffffffff832bec3a>] entry_SYSCALL_64_fastpath+0x31/0xb3 Could the following patches be applied to v4.4.y? * 4aa68e07d845 ("KEYS: restrict /proc/keys by credentials at open time") * ede0fa98a900 ("KEYS: always initialize keyring_index_key::desc_len") Note: queue-4.4 currently has a backport for "keys-always-initialize-keyring_index_key-desc_len.patch". This request is to apply the 2 patches above instead of just one, to 4.4.y, as the first patch is a bugfix as well. They apply cleanly if applied one after another. Tests: * Chrome OS tryjob * Syzkaller reproducer * Test to check if 4aa68e07d845 works as intended Thanks, - Zubin

[PATCH v4.9.y] KEYS: restrict /proc/keys by credentials at open time

by Zubin Mithra

From: Eric Biggers <ebiggers(a)google.com> commit 4aa68e07d845562561f5e73c04aa521376e95252 upstream When checking for permission to view keys whilst reading from /proc/keys, we should use the credentials with which the /proc/keys file was opened. This is because, in a classic type of exploit, it can be possible to bypass checks for the *current* credentials by passing the file descriptor to a suid program. Following commit 34dbbcdbf633 ("Make file credentials available to the seqfile interfaces") we can finally fix it. So let's do it. Signed-off-by: Eric Biggers <ebiggers(a)google.com> Signed-off-by: David Howells <dhowells(a)redhat.com> Signed-off-by: Zubin Mithra <zsm(a)chromium.org> --- * A test confirmed that when reading from a file descriptor corresponding to /proc/keys the permissions for the reader were being used instead of the permissions of the user who opened the file. This patch is required for 4.4.y as well; however, the original patch will apply cleanly there. I'll send a separate request for the same. security/keys/proc.c | 8 ++------ 1 file changed, 2 insertions(+), 6 deletions(-) diff --git a/security/keys/proc.c b/security/keys/proc.c index ec493ddadd111..f2c7e090a66d7 100644 --- a/security/keys/proc.c +++ b/security/keys/proc.c @@ -187,7 +187,7 @@ static int proc_keys_show(struct seq_file *m, void *v) struct keyring_search_context ctx = { .index_key = key->index_key, - .cred = current_cred(), + .cred = m->file->f_cred, .match_data.cmp = lookup_user_key_possessed, .match_data.raw_data = key, .match_data.lookup_type = KEYRING_SEARCH_LOOKUP_DIRECT, @@ -207,11 +207,7 @@ static int proc_keys_show(struct seq_file *m, void *v) } } - /* check whether the current task is allowed to view the key (assuming - * non-possession) - * - the caller holds a spinlock, and thus the RCU read lock, making our - * access to __current_cred() safe - */ + /* check whether the current task is allowed to view the key */ rc = key_task_permission(key_ref, ctx.cred, KEY_NEED_VIEW); if (rc < 0) return 0; -- 2.21.0.360.g471c308f928-goog

Please apply 8b23570ab001c (4.9, 4.14) ("ACPICA: Reference Counts: increase max to 0x4000 for large servers")

by van der Linden, Frank

commit upstream 8b23570ab001c1982c8a068cde468ff067255314 This commit ("ACPICA: Reference Counts: increase max to 0x4000 for large servers") fixes an issue that has been seen on large memory systems. The first release with the fix was 4.19. It's a low risk fix, and the value has been bumped in the past already. It should be fine on anything below 4.19, but I've only included 4.9 and 4.14 here, since the issue was actually observed on those versions. Thanks, Frank

[PATCH v4] mm/hotplug: fix offline undo_isolate_page_range()

by Qian Cai

The commit f1dd2cd13c4b ("mm, memory_hotplug: do not associate hotadded memory to zones until online") introduced move_pfn_range_to_zone() which calls memmap_init_zone() during onlining a memory block. memmap_init_zone() will reset pagetype flags and makes migrate type to be MOVABLE. However, in __offline_pages(), it also call undo_isolate_page_range() after offline_isolated_pages() to do the same thing. Due to the commit 2ce13640b3f4 ("mm: __first_valid_page skip over offline pages") changed __first_valid_page() to skip offline pages, undo_isolate_page_range() here just waste CPU cycles looping around the offlining PFN range while doing nothing, because __first_valid_page() will return NULL as offline_isolated_pages() has already marked all memory sections within the pfn range as offline via offline_mem_sections(). Also, after calling the "useless" undo_isolate_page_range() here, it reaches the point of no returning by notifying MEM_OFFLINE. Those pages will be marked as MIGRATE_MOVABLE again once onlining. The only thing left to do is to decrease the number of isolated pageblocks zone counter which would make some paths of the page allocation slower that the above commit introduced. Even if alloc_contig_range() can be used to isolate 16GB-hugetlb pages on ppc64, an "int" should still be enough to represent the number of pageblocks there. Fix an incorrect comment along the way. Fixes: 2ce13640b3f4 ("mm: __first_valid_page skip over offline pages") Cc: <stable(a)vger.kernel.org> # v4.13+ Acked-by: Michal Hocko <mhocko(a)suse.com> Reviewed-by: Oscar Salvador <osalvador(a)suse.de> Signed-off-by: Qian Cai <cai(a)lca.pw> --- v4: Further consolidate comments.

[PATCH] clk: mvebu: armada-37xx-periph: Fix initialization for cpu clocks

by Gregory CLEMENT

The clock parenting was not setup properly when DVFS was enabled. It was expected that the same clock source was used with and without DVFS which was not the case.

[PATCH 1/2] cpufreq: armada-37xx: fix clock parenting

by Gregory CLEMENT

From: Christian Neubert <christian.neubert.86(a)gmail.com> The clock parenting was not setup properly when DVFS was enabled. It was expected that the same clock source was used with and without DVFS which was not the case. This patch fixes this issue, allowing to make the cpufreq support work when the CPU clock source are not the default ones.
