[PATCH 0/2 linux-stable-4.4] ath10k: rebuild crypto header in rx data frames

by Sriram R

ath10k has a replay detection issue which was fixed in v4.14 and we would like to get this security fix also to linux-stable-4.4.But for that it depends on 3 mac80211 patches so the below mac80211 commits needs to be picked first in the same order and then apply this patchset. f980ebc058c2 : mac80211: allow not sending MIC up from driver for HW crypto f631a77ba920 : mac80211: allow same PN for AMSDU sub-frames cef0acd4d7d4 : mac80211: Add RX flag to indicate ICV stripped These patches should be applied in that order(commit f980ebc058c2 first) and they should apply cleanly with 3-way merge.

[PATCH] pmem: fix badblocks population for raw mode

by Toshi Kani

pmem_attach_disk() calls nvdimm_badblocks_populate() with resource range uninitialized in the case of raw mode. This leads the pmem driver to hit MCE despite of ARS reporting the range bad. Initialize 'bb_res' for raw mode.

[PATCH 7/7] tracepoint: Do not warn on ENOMEM

by Steven Rostedt

From: Mathieu Desnoyers <mathieu.desnoyers(a)efficios.com> Tracepoint should only warn when a kernel API user does not respect the required preconditions (e.g. same tracepoint enabled twice, or called to remove a tracepoint that does not exist). Silence warning in out-of-memory conditions, given that the error is returned to the caller. This ensures that out-of-memory error-injection testing does not trigger warnings in tracepoint.c, which were seen by syzbot.

[PATCH 1/7] tracing: Fix bad use of igrab in trace_uprobe.c

by Steven Rostedt

From: Song Liu <songliubraving(a)fb.com> As Miklos reported and suggested: This pattern repeats two times in trace_uprobe.c and in kernel/events/core.c as well: ret = kern_path(filename, LOOKUP_FOLLOW, &path); if (ret) goto fail_address_parse; inode = igrab(d_inode(path.dentry)); path_put(&path); And it's wrong. You can only hold a reference to the inode if you have an active ref to the superblock as well (which is normally through path.mnt) or holding s_umount. This way unmounting the containing filesystem while the tracepoint is active will give you the "VFS: Busy inodes after unmount..." message and a crash when the inode is finally put. Solution: store path instead of inode. This patch fixes two instances in trace_uprobe.c. struct path is added to struct trace_uprobe to keep the inode and containing mount point referenced.

This patch is the 2nd one of a series of patches. If you want to add it to the stable tree without the first patch, you must add a + kfree(func_name); before returning from the function.

Please apply 1572e45a924f ("perf/core: Fix the perf_cpu_time ...") to v4.9.y and older

by Guenter Roeck

Hi Greg, upstream commit 1572e45a924f ("perf/core: Fix the perf_cpu_time_max_percent check") fixes CVE-2017-18255. Please apply to v4.9.y and older. The patch applies cleanly to v4.9.y and v4.4.y; I didn't check older kernels. More recent kernels are not affected. Thanks, Guenter

I would advise not to include this patch in the previous stable trees. This patch does not fix any critical bug and for some very specific microbenchmarks on very large machines, it has shown performance regression. So, I don't think it is worth the risk. > From foo@baz Tue May 1 16:18:19 PDT 2018 > From: Shakeel Butt <shakeelb(a)google.com> > Date: Wed, 21 Feb 2018 14:45:28 -0800 > Subject: mm, mlock, vmscan: no more skipping pagevecs > From: Shakeel Butt <shakeelb(a)google.com> > [ Upstream commit 9c4e6b1a7027f102990c0395296015a812525f4d ] > When a thread mlocks an address space backed either by file pages which > are currently not present in memory or swapped out anon pages (not in > swapcache), a new page is allocated and added to the local pagevec > (lru_add_pvec), I/O is triggered and the thread then sleeps on the page. > On I/O completion, the thread can wake on a different CPU, the mlock > syscall will then sets the PageMlocked() bit of the page but will not be > able to put that page in unevictable LRU as the page is on the pagevec > of a different CPU.

[PATCH v3] module: Fix display of wrong module .text address

by Thomas Richter

Reading file /proc/modules shows the correct address: [root@s35lp76 ~]# cat /proc/modules | egrep '^qeth_l2' qeth_l2 94208 1 - Live 0x000003ff80401000 and reading file /sys/module/qeth_l2/sections/.text [root@s35lp76 ~]# cat /sys/module/qeth_l2/sections/.text 0x0000000018ea8363 displays a random address. This breaks the perf tool which uses this address on s390 to calculate start of .text section in memory. Fix this by printing the correct (unhashed) address. Thanks to Jessica Yu for helping on this.

[PATCH] ext4: fix bitmap position validation

by Lukas Czerner

Currently in ext4_valid_block_bitmap() we expect the bitmap to be positioned anywhere between 0 and s_blocksize clusters, but that's wrong because the bitmap can be placed anywhere in the block group. This causes false positives when validating bitmaps on perfectly valid file system layouts. Fix it by checking whether the bitmap is within the group boundary. The problem can be reproduced using the following mkfs -t ext3 -E stride=256 /dev/vdb1 mount /dev/vdb1 /mnt/test cd /mnt/test wget https://cdn.kernel.org/pub/linux/kernel/v4.x/linux-4.16.3.tar.xz tar xf linux-4.16.3.tar.xz This will result in the warnings in the logs EXT4-fs error (device vdb1): ext4_validate_block_bitmap:399: comm tar: bg 84: block 2774529: invalid block bitmap Signed-off-by: Lukas Czerner <lczerner(a)redhat.com> Reported-by: Ilya Dryomov <idryomov(a)gmail.com> Fixes: 7dac4a1726a9 ("ext4: add validity checks for bitmap block numbers") Cc: stable(a)vger.kernel.org --- fs/ext4/balloc.c | 10 ++++++---- 1 file changed, 6 insertions(+), 4 deletions(-) diff --git a/fs/ext4/balloc.c b/fs/ext4/balloc.c index a33d8fb..0c0e383 100644 --- a/fs/ext4/balloc.c +++ b/fs/ext4/balloc.c @@ -338,7 +338,8 @@ static ext4_fsblk_t ext4_valid_block_bitmap(struct super_block *sb, /* check whether block bitmap block number is set */ blk = ext4_block_bitmap(sb, desc); offset = blk - group_first_block; - if (offset < 0 || EXT4_B2C(sbi, offset) >= sb->s_blocksize || + if (offset < 0 || + EXT4_B2C(sbi, offset) >= EXT4_CLUSTERS_PER_GROUP(sb) || !ext4_test_bit(EXT4_B2C(sbi, offset), bh->b_data)) /* bad block bitmap */ return blk; @@ -346,7 +347,8 @@ static ext4_fsblk_t ext4_valid_block_bitmap(struct super_block *sb, /* check whether the inode bitmap block number is set */ blk = ext4_inode_bitmap(sb, desc); offset = blk - group_first_block; - if (offset < 0 || EXT4_B2C(sbi, offset) >= sb->s_blocksize || + if (offset < 0 || + EXT4_B2C(sbi, offset) >= EXT4_CLUSTERS_PER_GROUP(sb) || !ext4_test_bit(EXT4_B2C(sbi, offset), bh->b_data)) /* bad block bitmap */ return blk; @@ -354,8 +356,8 @@ static ext4_fsblk_t ext4_valid_block_bitmap(struct super_block *sb, /* check whether the inode table block number is set */ blk = ext4_inode_table(sb, desc); offset = blk - group_first_block; - if (offset < 0 || EXT4_B2C(sbi, offset) >= sb->s_blocksize || - EXT4_B2C(sbi, offset + sbi->s_itb_per_group) >= sb->s_blocksize) + if (offset < 0 || EXT4_B2C(sbi, offset + sbi->s_itb_per_group) >= + EXT4_CLUSTERS_PER_GROUP(sb)) return blk; next_zero_bit = ext4_find_next_zero_bit(bh->b_data, EXT4_B2C(sbi, offset + sbi->s_itb_per_group), -- 2.7.5
