When a lba either hits the cache or corresponds to an empty entry in the L2P table, we need to advance the bio according to the position in which the lba is located. Otherwise, we will copy data in the wrong page, thus causing data corruption for the application. In case of a cache hit, we assumed that bio->bi_iter.bi_idx would contain the correct index, but this is no necessarily true. Instead, use the local bio advance counter and iterator. This guarantees that lbas hitting the cache are copied into the right bv_page. In case of an empty L2P entry, we omitted to advance the bio. In the cases when the same I/O also contains a cache hit, data corresponding to this lba will be copied to the wrong bv_page. Fix this by advancing the bio as we do in the case of a cache hit.

With a misbehaving controller it's possible we'll never enter the live state and create an admin queue. When we fail out of reset work it's possible we failed out early enough without setting up the admin queue. We tear down queues after a failed reset, but needed to do some more sanitization.

If our device loses its connection for longer than the dead timeout we will set NBD_DISCONNECTED in order to quickly fail any pending IO's that flood in after the IO's that were waiting during the dead timer. However if we re-connect at some point in the future we'll still see this DISCONNECTED flag set if we then lose our connection again after that, which means we won't get notifications for our newly lost connections. Fix this by just clearing the DISCONNECTED flag on reconnect in order to make sure everything works as it's supposed to.

由 James Smart 提交于
The FC-NVME spec hasn't locked down on the format string for TRADDR. Currently the spec is lobbying for "nn-<16hexdigits>:pn-<16hexdigits>" where the wwn's are hex values but not prefixed by 0x. Most implementations so far expect a string format of "nn-0x<16hexdigits>:pn-0x<16hexdigits>" to be used. The transport uses the match_u64 parser which requires a leading 0x prefix to set the base properly. If it's not there, a match will either fail or return a base 10 value. The resolution in T11 is pushing out. Therefore, to fix things now and to cover any eventuality and any implementations already in the field, this patch adds support for both formats. The change consists of replacing the token matching routine with a routine that validates the fixed string format, and then builds a local copy of the hex name with a 0x prefix before calling the system parser. Note: the same parser routine exists in both the initiator and target transports. Given this is about the only "shared" item, we chose to replicate rather than create an interdendency on some shared code.

There are cases where threads are in the process of submitting new io when the LLDD calls in to remove the remote port. In some cases, the next io actually goes to the LLDD, who knows the remoteport isn't present and rejects it. To properly recovery/restart these i/o's we don't want to hard fail them, we want to treat them as temporary resource errors in which a delayed retry will work. Add a couple more checks on remoteport connectivity and commonize the busy response handling when it's seen.

This is because by default the OSS nbd client doesn't set a timeout, so we end up setting the sndtimeo to 0, which of course means we have send errors a lot.

When mapping a directory, we want the MAY_WRITE permissions to reflect whether or not we have permission to modify, add and delete the directory entries. MAY_EXEC must map to lookup permissions. On the other hand, for files, we want MAY_WRITE to reflect a permission to modify and extend the file.

Commit 3d476263 ("tcp: remove poll() flakes when receiving RST") in v4.12 changed the order in which ->sk_state_change() and ->sk_error_report() are called when a socket is shut down - sk_state_change() is now called first. This causes xs_tcp_state_change() -> xs_sock_mark_closed() -> xprt_disconnect_done() to wake all pending tasked with -EAGAIN. When the ->sk_error_report() callback arrives, it is too late to pass the error on, and it is lost. As easy way to demonstrate the problem caused is to try to start rpc.nfsd while rcpbind isn't running. nfsd will attempt a tcp connection to rpcbind. A ECONNREFUSED error is returned, but sunrpc code loses the error and keeps retrying. If it saw the ECONNREFUSED, it would abort. To fix this, handle the sk->sk_err in the TCP_CLOSE branch of xs_tcp_state_change().
