2019-03-05fs: Make splice() and tee() take into account O_NONBLOCK flag on pipesSlavomir Kaslev1-0/+12
The current implementation of splice() and tee() ignores O_NONBLOCK set on pipe file descriptors and checks only the SPLICE_F_NONBLOCK flag for blocking on pipe arguments. This is inconsistent since splice()-ing from/to non-pipe file descriptors does take O_NONBLOCK into consideration. Fix this by promoting O_NONBLOCK, when set on a pipe, to SPLICE_F_NONBLOCK. Some context for how the current implementation of splice() leads to inconsistent behavior. In the ongoing work[1] to add VM tracing capability to trace-cmd we stream tracing data over named FIFOs or vsockets from guests back to the host. When we receive SIGINT from user to stop tracing, we set O_NONBLOCK on the input file descriptor and set SPLICE_F_NONBLOCK for the next call to splice(). If splice() was blocked waiting on data from the input FIFO, after SIGINT splice() restarts with the same arguments (no SPLICE_F_NONBLOCK) and blocks again instead of returning -EAGAIN when no data is available. This differs from the splice() behavior when reading from a vsocket or when we're doing a traditional read()/write() loop (trace-cmd's --nosplice argument). With this patch applied we get the same behavior in all situations after setting O_NONBLOCK which also matches the behavior of doing a read()/write() loop instead of splice(). This change does have potential of breaking users who don't expect EAGAIN from splice() when SPLICE_F_NONBLOCK is not set. OTOH programs that set O_NONBLOCK and don't anticipate EAGAIN are arguably buggy[2].

2019-03-04net/mlx5e: Update tx reporter status in case channels were successfully openedEran Ben Elisha1-0/+4
Once channels were successfully opened, update tx reporter health state to healthy. This is needed for the following scenario: - SQ has an un-recovered error reported to the devlink health, resulting tx reporter state to be error. - Current channels (including this SQ) are closed - New channels are opened After that flow, the original error was "solved", and tx reporter state should be healthy. However, as it was resolved as a side effect, and not via tx reporter recover method, driver needs to inform devlink health about it.

2019-03-04devlink: Add support for direct reporter health state updateEran Ben Elisha3-5/+62
It is possible that a reporter state will be updated due to a recover flow which is not triggered by a devlink health related operation, but as a side effect of some other operation in the system. Expose devlink health API for a direct update of a reporter status. Move devlink_health_reporter_state enum definition to devlink.h so it could be used from drivers as a parameter of devlink_health_reporter_state_update. In addition, add trace_devlink_health_reporter_state_update to provide user notification for reporter state change.

If devlink_health_report() aborted the recover flow due to grace period checker, it left the reporter status as DEVLINK_HEALTH_REPORTER_STATE_HEALTHY, which is a bug. Fix that by always setting the reporter state to DEVLINK_HEALTH_REPORTER_STATE_ERROR prior to running the checker mentioned above. In addition, save the previous health_state in a temporary variable, then use it in the abort check comparison instead of using reporter->health_state which might be already changed.

2019-03-04ip6mr: Do not call __IP6_INC_STATS() from preemptible contextIdo Schimmel1-4/+4
Similar to commit 44f49dd8b5a6 ("ipmr: fix possible race resulting from improper usage of IP_INC_STATS_BH() in preemptible context."), we cannot assume preemption is disabled when incrementing the counter and accessing a per-CPU variable. Preemption can be enabled when we add a route in process context that corresponds to packets stored in the unresolved queue, which are then forwarded using this route [1]. Fix this by using IP6_INC_STATS() which takes care of disabling preemption on architectures where it is needed.

2019-03-04get rid of legacy 'get_ds()' functionLinus Torvalds33-52/+16
Every in-kernel use of this function defined it to KERNEL_DS (either as an actual define, or as an inline function). It's an entirely historical artifact, and long long long ago used to actually read the segment selector valueof '%ds' on x86. Which in the kernel is always KERNEL_DS. Inspired by a patch from Jann Horn that just did this for a very small subset of users (the ones in fs/), along with Al who suggested a script. I then just took it to the logical extreme and removed all the remaining gunk. Roughly scripted with git grep -l '(get_ds())' -- :^tools/ | xargs sed -i 's/(get_ds())/(KERNEL_DS)/' git grep -lw 'get_ds' -- :^tools/ | xargs sed -i '/^#define get_ds()/d' plus manual fixups to remove a few unusual usage patterns, the couple of inline function cases and to fix up a comment that had become stale. The 'get_ds()' function remains in an x86 kvm selftest, since in user space it actually does something relevant.

2019-03-04aio: simplify - and fix - fget/fput for io_submit()Linus Torvalds2-44/+36
Al Viro root-caused a race where the IOCB_CMD_POLL handling of fget/fput() could cause us to access the file pointer after it had already been freed: "In more details - normally IOCB_CMD_POLL handling looks so: 1) io_submit(2) allocates aio_kiocb instance and passes it to aio_poll() 2) aio_poll() resolves the descriptor to struct file by req->file = fget(iocb->aio_fildes) 3) aio_poll() sets ->woken to false and raises ->ki_refcnt of that aio_kiocb to 2 (bumps by 1, that is). 4) aio_poll() calls vfs_poll(). After sanity checks (basically, "poll_wait() had been called and only once") it locks the queue. That's what the extra reference to iocb had been for - we know we can safely access it. 5) With queue locked, we check if ->woken has already been set to true (by aio_poll_wake()) and, if it had been, we unlock the queue, drop a reference to aio_kiocb and bugger off - at that point it's a responsibility to aio_poll_wake() and the stuff called/scheduled by it. That code will drop the reference to file in req->file, along with the other reference to our aio_kiocb. 6) otherwise, we see whether we need to wait. If we do, we unlock the queue, drop one reference to aio_kiocb and go away - eventual wakeup (or cancel) will deal with the reference to file and with the other reference to aio_kiocb 7) otherwise we remove ourselves from waitqueue (still under the queue lock), so that wakeup won't get us. No async activity will be happening, so we can safely drop req->file and iocb ourselves. If wakeup happens while we are in vfs_poll(), we are fine - aio_kiocb won't get freed under us, so we can do all the checks and locking safely. And we don't touch ->file if we detect that case. However, vfs_poll() most certainly *does* touch the file it had been given. So wakeup coming while we are still in ->poll() might end up doing fput() on that file. That case is not too rare, and usually we are saved by the still present reference from descriptor table - that fput() is not the final one. But if another thread closes that descriptor right after our fget() and wakeup does happen before ->poll() returns, we are in trouble - final fput() done while we are in the middle of a method: Al also wrote a patch to take an extra reference to the file descriptor to fix this, but I instead suggested we just streamline the whole file pointer handling by submit_io() so that the generic aio submission code simply keeps the file pointer around until the aio has completed.

2019-03-04x86-64: add warning for non-canonical user access address dereferencesLinus Torvalds1-0/+1
This adds a warning (once) for any kernel dereference that has a user exception handler, but accesses a non-canonical address. It basically is a simpler - and more limited - version of commit 9da3f2b74054 ("x86/fault: BUG() when uaccess helpers fault on kernel addresses") that got reverted. Note that unlike that original commit, this only causes a warning, because there are real situations where we currently can do this (notably speculative argument fetching for uprobes etc). Also, unlike that original commit, this _only_ triggers for #GP accesses, so the cases of valid kernel pointers that cross into a non-mapped page aren't affected. The intent of this is two-fold: - the uprobe/tracing accesses really do need to be more careful. In particular, from a portability standpoint it's just wrong to think that "a pointer is a pointer", and use the same logic for any random pointer value you find on the stack. It may _work_ on x86-64, but it doesn't necessarily work on other architectures (where the same pointer value can be either a kernel pointer _or_ a user pointer, and you really need to be much more careful in how you try to access it) The warning can hopefully end up being a reminder that just any random pointer access won't do. - Kees in particular wanted a way to actually report invalid uses of wild pointers to user space accessors, instead of just silently failing them. Automated fuzzers want a way to get reports if the kernel ever uses invalid values that the fuzzer fed it. The non-canonical address range is a fair chunk of the address space, and with this you can teach syzkaller to feed in invalid pointer values and find cases where we do not properly validate user addresses (possibly due to bad uses of "set_fs()").
