I'm announcing the release of the 4.4.195 kernel. All users of the 4.4 kernel series must upgrade. The updated 4.4.y git tree can be found at: git://git.kernel.org/pub/scm/linux/kernel/git/stable/linux-stable.git linux-4.4.y and can be browsed at the normal kernel.org git web browser: https://git.kernel.org/?p=linux/kernel/git/stable/linux-stable.git;a=summary thanks, greg k-h ------------ Makefile | 2 -

Re: Patch "clk: jz4740: Add TCU clock" has been added to the 4.4-stable tree

by Paul Cercueil

Hi Sasha, I think this patch shouldn't be added to the stable trees; it will cause the TCU clock to be managed by the clock framework and automatically gated after bootup since it has no client, causing a global system lockup. It's only really applicable to 5.3.

[v4.14.y] bpf: fix use after free in prog symbol exposure

Problem is that symbol exposure via bpf_prog_kallsyms_add() but also perf_event_bpf_event() were done /after/ bpf_prog_new_fd(). Once the fd is exposed to the public, a parallel close request came in right before we attempted to do the bpf_prog_kallsyms_add(). Given at this time the prog reference count is one, we start to rip everything underneath us via bpf_prog_release() -> bpf_prog_put(). The memory is eventually released via deferred free, so we're seeing that bpf_jit_free() has a kallsym entry because we added it from bpf_prog_load() but /after/ bpf_prog_put() from the remote CPU. Therefore, move both notifications /before/ we install the fd. The issue was never seen between bpf_prog_alloc_id() and bpf_prog_new_fd() because upon bpf_prog_get_fd_by_id() we'll take another reference to the BPF prog, so we're still holding the original reference from the bpf_prog_load().

[PATCH] block: mq-deadline: Fix queue restart handling

by Damien Le Moal

[ Upstream commit cb8acabbe33b110157955a7425ee876fb81e6bbc ] Commit 7211aef86f79 ("block: mq-deadline: Fix write completion handling") added a call to blk_mq_sched_mark_restart_hctx() in dd_dispatch_request() to make sure that write request dispatching does not stall when all target zones are locked. This fix left a subtle race when a write completion happens during a dispatch execution on another CPU: CPU 0: Dispatch CPU1: write completion dd_dispatch_request() lock(&dd->lock); ... lock(&dd->zone_lock); dd_finish_request() rq = find request lock(&dd->zone_lock); unlock(&dd->zone_lock); zone write unlock unlock(&dd->zone_lock); ... __blk_mq_free_request check restart flag (not set) -> queue not run ... if (!rq && have writes) blk_mq_sched_mark_restart_hctx() unlock(&dd->lock) Since the dispatch context finishes after the write request completion handling, marking the queue as needing a restart is not seen from __blk_mq_free_request() and blk_mq_sched_restart() not executed leading to the dispatch stall under 100% write workloads. Fix this by moving the call to blk_mq_sched_mark_restart_hctx() from dd_dispatch_request() into dd_finish_request() under the zone lock to ensure full mutual exclusion between write request dispatch selection and zone unlock on write request completion.

[PATCH AUTOSEL 4.19 01/33] MIPS: Ingenic: Disable broken BTB lookup optimization.

From: Zhou Yanjie <zhouyanjie(a)zoho.com> [ Upstream commit 053951dda71ecb4b554a2cdbe26f5f6f9bee9dd2 ] In order to further reduce power consumption, the XBurst core by default attempts to avoid branch target buffer lookups by detecting & special casing loops.
