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

2020-01-09mtd: spi-nor: Fix the writing of the Status Register on micron flashesTudor Ambarus1-0/+1
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.

2020-01-09fs: move guard_bio_eod() after bio_set_op_attrsMing Lei4-7/+17
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.

2020-01-08pstore/ram: Regularize prz label allocation lifetimeKees Cook2-3/+3
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.

2020-01-08tipc: fix wrong connect() return codeTuong Lien1-2/+2
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.

2020-01-08tipc: fix link overflow issue at socket shutdownTuong Lien1-21/+32
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.
