[PATCH 3.16] staging: usbip stub_rx fix static checker warning on unnecessary checks

Patch to consider for stable 3.18, 4.4 and 4.9

by Tomasz Kramkowski

In September last year, Ben Hutchings submitted commit [9547837bdccb] for 3.16.48-rc1 and I informed him that it would be useless without [3f3752705dbd] (and that maybe [c3883fe06488] would be useful as well). Ben dropped the patch but suggested I email this list with the information of the other two patches but I never quite got around to it. Now I see Sasha Levin is submitting [3f3752705dbd] and [c3883fe06488] for 4.9, 4.4 and 3.18 it would now make sense to include [9547837bdccb]. This patch fixes a minor problem where a certain USB adapter for Sega Genesis controllers appears as one input device when it has two ports for two controllers. I imagine some users of emulator distributions might use stable kernels and might benefit from this fix. I'm actually not entirely sure that patch is something suitable for stable but since it was already submitted once then I don't think it hurts to bring it up again (despite it breaking stable-kernel-rules as far as I understand it). Commits mentioned: [9547837bdccb]: HID: usbhid: add quirk for innomedia INNEX GENESIS/ATARI adapter [3f3752705dbd]: HID: reject input outside logical range only if null state is set [c3883fe06488]: HID: clamp input to logical range if no null state If the patch [9547837bdccb] is not relevant then feel free to ignore this email. Thanks, -- Tomasz Kramkowski

[PATCH RESEND] ocfs2: fix a misuse a of brelse after failing ocfs2_check_dir_entry

by Changwei Ge

From: Changwei Ge <ge.changwei(a)h3c.com> Somehow, file system metadata was corrupted, which causes ocfs2_check_dir_entry() to fail in function ocfs2_dir_foreach_blk_el(). According to the original design intention, if above happens we should skip the problematic block and continue to retrieve dir entry. But there is obviouse misuse of brelse around related code. After failure of ocfs2_check_dir_entry(), currunt code just moves to next position and uses the problematic buffer head again and again during which the problematic buffer head is released for multiple times. I suppose, this a serious issue which is long-lived in ocfs2. This may cause other file systems which is also used in a the same host insane. So we should also consider about bakcporting this patch into linux -stable.

So, the overcommit logic should treat it as free. Otherwise, it's possible to cause random system-wide memory allocation failures by consuming a significant amount of memory by indirectly reclaimable memory, e.g. dentry external names. If overcommit policy GUESS is used, it might be used for denial of service attack under some conditions. The following program illustrates the approach. It causes the kernel to allocate an unreclaimable kmalloc-256 chunk for each stat() call, so that at some point the overcommit logic may start blocking large allocation system-wide. int main() { char buf[256]; unsigned long i; struct stat statbuf; buf[0] = '/'; for (i = 1; i < sizeof(buf); i++) buf[i] = '_'; for (i = 0; 1; i++) { sprintf(&buf[248], "%8lu", i); stat(buf, &statbuf); } return 0; } This patch in combination with related indirectly reclaimable memory patches closes this issue.

[PATCH] cdrom: Fix info leak/OOB read in cdrom_ioctl_drive_status

by Scott Bauer

Like d88b6d04: "cdrom: information leak in cdrom_ioctl_media_changed()" There is another cast from unsigned long to int which causes a bounds check to fail with specially crafted input. The value is then used as an index in the slot array in cdrom_slot_status().

[Linux-stable-mirror] [PATCH] soc/tegra: pmc: fix child-node lookup

by Johan Hovold

Fix child-node lookup during probe, which ended up searching the whole device tree depth-first starting at the parent rather than just matching on its children. To make things worse, the parent pmc node could end up being prematurely freed as of_find_node_by_name() drops a reference to its first argument.
