606e9ad Linus Torvalds 11 January 2020, 23:33:48 UTC Merge tag 'clone3-tls-v5.5-rc6' of git://git.kernel.org/pub/scm/linux/kernel/git/brauner/linux Pull thread fixes from Christian Brauner: "This contains a series of patches to fix CLONE_SETTLS when used with clone3(). The clone3() syscall passes the tls argument through struct clone_args instead of a register. This means, all architectures that do not implement copy_thread_tls() but still support CLONE_SETTLS via copy_thread() expecting the tls to be located in a register argument based on clone() are currently unfortunately broken. Their tls value will be garbage. The patch series fixes this on all architectures that currently define __ARCH_WANT_SYS_CLONE3. It also adds a compile-time check to ensure that any architecture that enables clone3() in the future is forced to also implement copy_thread_tls(). My ultimate goal is to get rid of the copy_thread()/copy_thread_tls() split and just have copy_thread_tls() at some point in the not too distant future (Maybe even renaming copy_thread_tls() back to simply copy_thread() once the old function is ripped from all arches). This is dependent now on all arches supporting clone3(). While all relevant arches do that now there are still four missing: ia64, m68k, sh and sparc. They have the system call reserved, but not implemented. Once they all implement clone3() we can get rid of ARCH_WANT_SYS_CLONE3 and HAVE_COPY_THREAD_TLS. This series also includes a minor fix for the arm64 uapi headers which caused __NR_clone3 to be missing from the exported user headers. Unfortunately the series came in a little late especially given that it touches a range of architectures. Due to the holidays not all arch maintainers responded in time probably due to their backlog. Will and Arnd have thankfully acked the arm specific changes. Given that the changes are straightforward and rather minimal combined with the fact the that clone3() with CLONE_SETTLS is broken I decided to send them post rc3 nonetheless" * tag 'clone3-tls-v5.5-rc6' of git://git.kernel.org/pub/scm/linux/kernel/git/brauner/linux: um: Implement copy_thread_tls clone3: ensure copy_thread_tls is implemented xtensa: Implement copy_thread_tls riscv: Implement copy_thread_tls parisc: Implement copy_thread_tls arm: Implement copy_thread_tls arm64: Implement copy_thread_tls arm64: Move __ARCH_WANT_SYS_CLONE3 definition to uapi headers 11 January 2020, 23:33:48 UTC

Adjust the timings to ensure that we meet what is stipulated as the minimum timings to ensure that all devices correctly interpret the STOP bus transition. This is more important than trying to generate a square wave with even duty cycle.

82de6a6 Tudor Ambarus 03 December 2019, 14:50:01 UTC mtd: spi-nor: Fix the writing of the Status Register on micron flashes Micron flashes do not support 16 bit writes on the Status Register. According to micron datasheets, when using the Write Status Register (01h) command, the chip select should be driven LOW and held LOW until the eighth bit of the last data byte has been latched in, after which it must be driven HIGH. If CS is not driven HIGH, the command is not executed, flag status register error bits are not set, and the write enable latch remains set to 1. This fixes the lock operations on micron flashes.

83c9c54 Ming Lei 05 January 2020, 01:41:14 UTC fs: move guard_bio_eod() after bio_set_op_attrs Commit 85a8ce62c2ea ("block: add bio_truncate to fix guard_bio_eod") adds bio_truncate() for handling bio EOD. However, bio_truncate() doesn't use the passed 'op' parameter from guard_bio_eod's callers. So bio_trunacate() may retrieve wrong 'op', and zering pages may not be done for READ bio. Fixes this issue by moving guard_bio_eod() after bio_set_op_attrs() in submit_bh_wbc() so that bio_truncate() can always retrieve correct op info. Meantime remove the 'op' parameter from guard_bio_eod() because it isn't used any more.

e163fdb Kees Cook 08 January 2020, 18:06:54 UTC pstore/ram: Regularize prz label allocation lifetime In my attempt to fix a memory leak, I introduced a double-free in the pstore error path. Instead of trying to manage the allocation lifetime between persistent_ram_new() and its callers, adjust the logic so persistent_ram_new() always takes a kstrdup() copy, and leaves the caller's allocation lifetime up to the caller. Therefore callers are _always_ responsible for freeing their label. Before, it only needed freeing when the prz itself failed to allocate, and not in any of the other prz failure cases, which callers would have no visibility into, which is the root design problem that lead to both the leak and now double-free bugs.

9546a0b Tuong Lien 08 January 2020, 02:19:00 UTC tipc: fix wrong connect() return code The current 'tipc_wait_for_connect()' function does a wait-loop for the condition 'sk->sk_state != TIPC_CONNECTING' to conclude if the socket connecting has done. However, when the condition is met, it returns '0' even in the case the connecting is actually failed, the socket state is set to 'TIPC_DISCONNECTING' (e.g. when the server socket has closed..). This results in a wrong return code for the 'connect()' call from user, making it believe that the connection is established and go ahead with building, sending a message, etc. but finally failed e.g. '-EPIPE'. This commit fixes the issue by changing the wait condition to the 'tipc_sk_connected(sk)', so the function will return '0' only when the connection is really established. Otherwise, either the socket 'sk_err' if any or '-ETIMEDOUT'/'-EINTR' will be returned correspondingly.

49afb80 Tuong Lien 08 January 2020, 02:18:15 UTC tipc: fix link overflow issue at socket shutdown When a socket is suddenly shutdown or released, it will reject all the unreceived messages in its receive queue. This applies to a connected socket too, whereas there is only one 'FIN' message required to be sent back to its peer in this case. In case there are many messages in the queue and/or some connections with such messages are shutdown at the same time, the link layer will easily get overflowed at the 'TIPC_SYSTEM_IMPORTANCE' backlog level because of the message rejections. As a result, the link will be taken down. Moreover, immediately when the link is re-established, the socket layer can continue to reject the messages and the same issue happens... The commit refactors the '__tipc_shutdown()' function to only send one 'FIN' in the situation mentioned above. For the connectionless case, it is unavoidable but usually there is no rejections for such socket messages because they are 'dest-droppable' by default. In addition, the new code makes the other socket states clear (e.g.'TIPC_LISTEN') and treats as a separate case to avoid misbehaving.

2f806c2 David S. Miller 08 January 2020, 20:45:53 UTC Merge branch 'net-ungraft-prio' Petr Machata says: ==================== When ungrafting from PRIO, replace child with FIFO When a child Qdisc is removed from one of the PRIO Qdisc's bands, it is replaced unconditionally by a NOOP qdisc. As a result, any traffic hitting that band gets dropped. That is incorrect--no Qdisc was explicitly added when PRIO was created, and after removal, none should have to be added either. In patch #2, this problem is fixed for PRIO by first attempting to create a default Qdisc and only falling back to noop when that fails. This pattern of attempting to create an invisible FIFO, using NOOP only as a fallback, is also seen in some other Qdiscs. The only driver currently offloading PRIO (and thus presumably the only one impacted by this) is mlxsw. Therefore patch #1 extends mlxsw to handle the replacement by an invisible FIFO gracefully. ==================== Signed-off-by: David S. Miller <davem@davemloft.net> 08 January 2020, 20:45:53 UTC

3971a53 Petr Machata 06 January 2020, 18:01:55 UTC mlxsw: spectrum_qdisc: Ignore grafting of invisible FIFO The following patch will change PRIO to replace a removed Qdisc with an invisible FIFO, instead of NOOP. mlxsw will see this replacement due to the graft message that is generated. But because FIFO does not issue its own REPLACE message, when the graft operation takes place, the Qdisc that mlxsw tracks under the indicated band is still the old one. The child handle (0:0) therefore does not match, and mlxsw rejects the graft operation, which leads to an extack message: Warning: Offloading graft operation failed. Fix by ignoring the invisible children in the PRIO graft handler. The DESTROY message of the removed Qdisc is going to follow shortly and handle the removal.

5fbf7a2 Tony Lindgren 07 January 2020, 15:26:24 UTC usb: musb: fix idling for suspend after disconnect interrupt When disconnected as USB B-device, suspend interrupt should come before diconnect interrupt, because the DP/DM pins are shorter than the VBUS/GND pins on the USB connectors. But we sometimes get a suspend interrupt after disconnect interrupt. In that case we have devctl set to 99 with VBUS still valid and musb_pm_runtime_check_session() wrongly thinks we have an active session. We have no other interrupts after disconnect coming in this case at least with the omap2430 glue. Let's fix the issue by checking the interrupt status again with delayed work for the devctl 99 case. In the suspend after disconnect case the devctl session bit has cleared by then and musb can idle. For a typical USB B-device connect case we just continue with normal interrupts.

eacc6df Jens Axboe 07 January 2020, 20:08:56 UTC io_uring: remove punt of short reads to async context We currently punt any short read on a regular file to async context, but this fails if the short read is due to running into EOF. This is especially problematic since we only do the single prep for commands now, as we don't reset kiocb->ki_pos. This can result in a 4k read on a 1k file returning zero, as we detect the short read and then retry from async context. At the time of retry, the position is now 1k, and we end up reading nothing, and hence return 0. Instead of trying to patch around the fact that short reads can be legitimate and won't succeed in case of retry, remove the logic to punt a short read to async context. Simply return it.

9554de3 Shiraz Saleem 07 January 2020, 16:22:23 UTC i40iw: Remove setting of VMA private data and use rdma_user_mmap_io vm_ops is now initialized in ib_uverbs_mmap() with the recent rdma mmap API changes. Earlier it was done in rdma_umap_priv_init() which would not be called unless a driver called rdma_user_mmap_io() in its mmap. i40iw does not use the rdma_user_mmap_io API but sets the vma's vm_private_data to a driver object. This now conflicts with the vm_op rdma_umap_close as priv pointer points to the i40iw driver object instead of the private data setup by core when rdma_user_mmap_io is called. This leads to a crash in rdma_umap_close with a mmap put being called when it should not have. Remove the redundant setting of the vma private_data in i40iw as it is not used. Also move i40iw over to use the rdma_user_mmap_io API. This gives the extra protection of having the mappings zapped when the context is detsroyed.

f30e277 Geert Uytterhoeven 30 December 2019, 13:27:34 UTC drm/fb-helper: Round up bits_per_pixel if possible When userspace requests a video mode parameter value that is not supported, frame buffer device drivers should round it up to a supported value, if possible, instead of just rejecting it. This allows applications to quickly scan for supported video modes. Currently this rule is not followed for the number of bits per pixel, causing e.g. "fbset -depth N" to fail, if N is smaller than the current number of bits per pixel. Fix this by returning an error only if bits per pixel is too large, and setting it to the current value otherwise. See also Documentation/fb/framebuffer.rst, Section 2 (Programmer's View of /dev/fb*").

4396393 Chen-Yu Tsai 07 January 2020, 07:01:13 UTC drm/sun4i: tcon: Set RGB DCLK min. divider based on hardware model In commit 0b8e7bbde5e7 ("drm/sun4i: tcon: Set min division of TCON0_DCLK to 1.") it was assumed that all TCON variants support a minimum divider of 1 if only DCLK was used. However, the oldest generation of hardware only supports minimum divider of 4 if only DCLK is used. If a divider of 1 was used on this old hardware, some scrolling artifact would appear. A divider of 2 seemed OK, but a divider of 3 had artifacts as well. Set the minimum divider when outputing to parallel RGB based on the hardware model, with a minimum of 4 for the oldest (A10/A10s/A13/A20) hardware, and a minimum of 1 for the rest. A value is not set for the TCON variants lacking channel 0. This fixes the scrolling artifacts seen on my A13 tablet. Fixes: 0b8e7bbde5e7 ("drm/sun4i: tcon: Set min division of TCON0_DCLK to 1.")

However, that recovery scheme was never implemented due to difficult corner cases, and so we no longer need to keep the power gating disabled.
