2020-08-03ceph: periodically send perf metrics to MDSesXiubo Li
This will send the caps/read/write/metadata metrics to any available MDS once per second, which will be the same as the userland client. It will skip the MDS sessions which don't support the metric collection, as the MDSs will close socket connections when they get an unknown type message. We can disable the metric sending via the disable_send_metrics module parameter.

2020-08-03libceph: replace HTTP links with HTTPS onesAlexander A. Klimov
Rationale: Reduces attack surface on kernel devs opening the links for MITM as HTTPS traffic is much harder to manipulate. Deterministic algorithm: For each file: If not .svg: For each line: If doesn't contain `\bxmlns\b`: For each link, `\bhttp://[^# \t\r\n]*(?:\w|/)`: If neither `\bgnu\.org/license`, nor `\bmozilla\.org/MPL\b`: If both the HTTP and HTTPS versions return 200 OK and serve the same content: Replace HTTP with HTTPS.

2020-07-30random: fix circular include dependency on arm64 after addition of percpu.hWilly Tarreau
Daniel Díaz and Kees Cook independently reported that commit f227e3ec3b5c ("random32: update the net random state on interrupt and activity") broke arm64 due to a circular dependency on include files since the addition of percpu.h in random.h. The correct fix would definitely be to move all the prandom32 stuff out of random.h but for backporting, a smaller solution is preferred. This one replaces linux/percpu.h with asm/percpu.h, and this fixes the problem on x86_64, arm64, arm, and mips. Note that moving percpu.h around didn't change anything and that removing it entirely broke differently. When backporting, such options might still be considered if this patch fails to help. [ It turns out that an alternate fix seems to be to just remove the troublesome <asm/pointer_auth.h> remove from the arm64 <asm/smp.h> that causes the circular dependency. But we might as well do the whole belt-and-suspenders thing, and minimize inclusion in <linux/random.h> too. Either will fix the problem, and both are good changes. - Linus ] Reported-by: Daniel Díaz <daniel.diaz@linaro.org> Reported-by: Kees Cook <keescook@chromium.org> Tested-by: Marc Zyngier <maz@kernel.org> Fixes: f227e3ec3b5c Cc: Stephen Rothwell <sfr@canb.auug.org.au> Signed-off-by: Willy Tarreau <w@1wt.eu> Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>

2020-07-29mlxsw: spectrum: Use different trap group for externally routed packetsIdo Schimmel
Cited commit mistakenly removed the trap group for externally routed packets (e.g., via the management interface) and grouped locally routed and externally routed packet traps under the same group, thereby subjecting them to the same policer. This can result in problems, for example, when FRR is restarted and suddenly all transient traffic is trapped to the CPU because of a default route through the management interface. Locally routed packets required to re-establish a BGP connection will never reach the CPU and the routing tables will not be re-populated. Fix this by using a different trap group for externally routed packets.

2020-07-29IB/rdmavt: Fix RQ counting issues causing use of an invalid RWQEMike Marciniszyn
The lookaside count is improperly initialized to the size of the Receive Queue with the additional +1. In the traces below, the RQ size is 384, so the count was set to 385. The lookaside count is then rarely refreshed. Note the high and incorrect count in the trace below: rvt_get_rwqe: [hfi1_0] wqe ffffc900078e9008 wr_id 55c7206d75a0 qpn c qpt 2 pid 3018 num_sge 1 head 1 tail 0, count 385 rvt_get_rwqe: (hfi1_rc_rcv+0x4eb/0x1480 [hfi1] <- rvt_get_rwqe) ret=0x1 The head,tail indicate there is only one RWQE posted although the count says 385 and we correctly return the element 0. The next call to rvt_get_rwqe with the decremented count: rvt_get_rwqe: [hfi1_0] wqe ffffc900078e9058 wr_id 0 qpn c qpt 2 pid 3018 num_sge 0 head 1 tail 1, count 384 rvt_get_rwqe: (hfi1_rc_rcv+0x4eb/0x1480 [hfi1] <- rvt_get_rwqe) ret=0x1 Note that the RQ is empty (head == tail) yet we return the RWQE at tail 1, which is not valid because of the bogus high count. Best case, the RWQE has never been posted and the rc logic sees an RWQE that is too small (all zeros) and puts the QP into an error state. In the worst case, a server slow at posting receive buffers might fool rvt_get_rwqe() into fetching an old RWQE and corrupt memory. Fix by deleting the faulty initialization code and creating an inline to fetch the posted count and convert all callers to use new inline.

2020-07-29random32: update the net random state on interrupt and activityWilly Tarreau
This modifies the first 32 bits out of the 128 bits of a random CPU's net_rand_state on interrupt or CPU activity to complicate remote observations that could lead to guessing the network RNG's internal state. Note that depending on some network devices' interrupt rate moderation or binding, this re-seeding might happen on every packet or even almost never. In addition, with NOHZ some CPUs might not even get timer interrupts, leaving their local state rarely updated, while they are running networked processes making use of the random state. For this reason, we also perform this update in update_process_times() in order to at least update the state when there is user or system activity, since it's the only case we care about.

The RCU dereference must occur prior to the comparison in __rht_ptr. This patch changes the order of RCU dereference so that it is done first and the result is then fed to __rht_ptr.

2020-07-28net/mlx5e: Modify uplink state on interface up/downRon Diskin
When setting the PF interface up/down, notify the firmware to update uplink state via MODIFY_VPORT_STATE, when E-Switch is enabled. This behavior will prevent sending traffic out on uplink port when PF is down, such as sending traffic from a VF interface which is still up. Currently when calling mlx5e_open/close(), the driver only sends PAOS command to notify the firmware to set the physical port state to up/down, however, it is not sufficient. When VF is in "auto" state, it follows the uplink state, which was not updated on mlx5e_open/close() before this patch. When switchdev mode is enabled and uplink representor is first enabled, set the uplink port state value back to its FW default "AUTO".

2020-07-27drm/drm_fb_helper: fix fbdev with sparc64Sam Ravnborg
Recent kernels have been reported to panic using the bochs_drm framebuffer under qemu-system-sparc64 which was bisected to commit 7a0483ac4ffc ("drm/bochs: switch to generic drm fbdev emulation"). The backtrace indicates that the shadow framebuffer copy in drm_fb_helper_dirty_blit_real() is trying to access the real framebuffer using a virtual address rather than use an IO access typically implemented using a physical (ASI_PHYS) access on SPARC. The fix is to replace the memcpy with memcpy_toio() from io.h. memcpy_toio() uses writeb() where the original fbdev code used sbus_memcpy_toio(). The latter uses sbus_writeb(). The difference between writeb() and sbus_memcpy_toio() is that writeb() writes bytes in little-endian, where sbus_writeb() writes bytes in big-endian. As endian does not matter for byte writes they are the same. So we can safely use memcpy_toio() here. Note that this only fixes bochs, in general fbdev helpers still have issues with mixing up system memory and __iomem space. Fixing that will require a lot more work. v3: - Improved changelog (Daniel) - Added FIXME to fbdev_use_iomem (Daniel) v2: - Added missing __iomem cast (kernel test robot) - Made changelog readable and fix typos (Mark) - Add flag to select iomem - and set it in the bochs driver Signed-off-by: Sam Ravnborg <sam@ravnborg.org> Reported-by: Mark Cave-Ayland <mark.cave-ayland@ilande.co.uk> Reported-by: kernel test robot <lkp@intel.com> Tested-by: Mark Cave-Ayland <mark.cave-ayland@ilande.co.uk> Reviewed-by: Daniel Vetter <daniel.vetter@ffwll.ch> Cc: Mark Cave-Ayland <mark.cave-ayland@ilande.co.uk> Cc: Thomas Zimmermann <tzimmermann@suse.de> Cc: Gerd Hoffmann <kraxel@redhat.com> Cc: "David S.

The !ATOMIC_IOMAP version of io_maping_init_wc will always return success, even when the ioremap fails. Since the ATOMIC_IOMAP version returns NULL when the init fails, and callers check for a NULL return on error this is unexpected.

2020-07-23tcp: allow at most one TLP probe per flightYuchung Cheng
Previously TLP may send multiple probes of new data in one flight. This happens when the sender is cwnd limited. After the initial TLP containing new data is sent, the sender receives another ACK that acks partial inflight. It may re-arm another TLP timer to send more, if no further ACK returns before the next TLP timeout (PTO) expires. The sender may send in theory a large amount of TLP until send queue is depleted. This only happens if the sender sees such irregular uncommon ACK pattern. But it is generally undesirable behavior during congestion especially. The original TLP design restrict only one TLP probe per inflight as published in "Reducing Web Latency: the Virtue of Gentle Aggression", SIGCOMM 2013. This patch changes TLP to send at most one probe per inflight. Note that if the sender is app-limited, TLP retransmits old data and did not have this issue.

2020-07-23dm integrity: fix integrity recalculation that is improperly skippedMikulas Patocka
Commit adc0daad366b62ca1bce3e2958a40b0b71a8b8b3 ("dm: report suspended device during destroy") broke integrity recalculation. The problem is dm_suspended() returns true not only during suspend, but also during resume. So this race condition could occur: 1. dm_integrity_resume calls queue_work(ic->recalc_wq, &ic->recalc_work) 2. integrity_recalc (&ic->recalc_work) preempts the current thread 3. integrity_recalc calls if (unlikely(dm_suspended(ic->ti))) goto unlock_ret; 4. integrity_recalc exits and no recalculating is done. To fix this race condition, add a function dm_post_suspending that is only true during the postsuspend phase and use it instead of dm_suspended().

2020-07-22x86, vmlinux.lds: Page-align end of ..page_aligned sectionsJoerg Roedel
On x86-32 the idt_table with 256 entries needs only 2048 bytes. It is page-aligned, but the end of the .bss..page_aligned section is not guaranteed to be page-aligned. As a result, objects from other .bss sections may end up on the same 4k page as the idt_table, and will accidentially get mapped read-only during boot, causing unexpected page-faults when the kernel writes to them. This could be worked around by making the objects in the page aligned sections page sized, but that's wrong. Explicit sections which store only page aligned objects have an implicit guarantee that the object is alone in the page in which it is placed. That works for all objects except the last one. That's inconsistent. Enforcing page sized objects for these sections would wreckage memory sanitizers, because the object becomes artificially larger than it should be and out of bound access becomes legit. Align the end of the .bss..page_aligned and .data..page_aligned section on page-size so all objects places in these sections are guaranteed to have their own page.

2020-07-21xfrm: Fix crash when the hold queue is used.Steffen Klassert
The commits "xfrm: Move dst->path into struct xfrm_dst" and "net: Create and use new helper xfrm_dst_child()." changed xfrm bundle handling under the assumption that xdst->path and dst->child are not a NULL pointer only if dst->xfrm is not a NULL pointer. That is true with one exception. If the xfrm hold queue is used to wait until a SA is installed by the key manager, we create a dummy bundle without a valid dst->xfrm pointer. The current xfrm bundle handling crashes in that case. Fix this by extending the NULL check of dst->xfrm with a test of the DST_XFRM_QUEUE flag.

2020-07-17asm-generic/mmiowb: Allow mmiowb_set_pending() when preemptible()Will Deacon
Although mmiowb() is concerned only with serialising MMIO writes occuring in contexts where a spinlock is held, the call to mmiowb_set_pending() from the MMIO write accessors can occur in preemptible contexts, such as during driver probe() functions where ordering between CPUs is not usually a concern, assuming that the task migration path provides the necessary ordering guarantees. Unfortunately, the default implementation of mmiowb_set_pending() is not preempt-safe, as it makes use of a a per-cpu variable to track its internal state. This has been reported to generate the following splat on riscv: | BUG: using smp_processor_id() in preemptible [00000000] code: swapper/0/1 | caller is regmap_mmio_write32le+0x1c/0x46 | CPU: 3 PID: 1 Comm: swapper/0 Not tainted 5.8.0-rc3-hfu+ #1 | Call Trace: | walk_stackframe+0x0/0x7a | dump_stack+0x6e/0x88 | regmap_mmio_write32le+0x18/0x46 | check_preemption_disabled+0xa4/0xaa | regmap_mmio_write32le+0x18/0x46 | regmap_mmio_write+0x26/0x44 | regmap_write+0x28/0x48 | sifive_gpio_probe+0xc0/0x1da Although it's possible to fix the driver in this case, other splats have been seen from other drivers, including the infamous 8250 UART, and so it's better to address this problem in the mmiowb core itself. Fix mmiowb_set_pending() by using the raw_cpu_ptr() to get at the mmiowb state and then only updating the 'mmiowb_pending' field if we are not preemptible (i.e. we have a non-zero nesting count).

git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/tty into master Pull tty/serial driver fixes from Greg KH: :Here are some small tty and serial driver fixes for 5.8-rc6. The largest set of patches in here is a revert of the sysrq changes that went into 5.8-rc1 but turned out to cause a noticable overhead and cpu usage. Other than that, there's a few small serial driver fixes to resolve reported issues, and finally resolving the spinlock init problem on many serial driver consoles.
