2019-11-06r8169: fix page read in r8168g_mdio_readHeiner Kallweit1-0/+3
Functions like phy_modify_paged() read the current page, on Realtek PHY's this means reading the value of register 0x1f. Add special handling for reading this register, similar to what we do already in r8168g_mdio_write(). Currently we read a random value that by chance seems to be 0 always.

2019-11-06SMB3: Fix persistent handles reconnectPavel Shilovsky1-0/+1
When the client hits a network reconnect, it re-opens every open file with a create context to reconnect a persistent handle. All create context types should be 8-bytes aligned but the padding was missed for that one. As a result, some servers don't allow us to reconnect handles and return an error. The problem occurs when the problematic context is not at the end of the create request packet. Fix this by adding a proper padding at the end of the reconnect persistent handle context.

Jakub Kicinski says: ==================== net/tls: add a TX lock Some time ago Pooja and Mallesham started reporting crashes with an async accelerator. After trying to poke the existing logic into shape I came to the conclusion that it can't be trusted, and to preserve our sanity we should just add a lock around the TX side. First patch removes the sk_write_pending checks from the write space callbacks. Those don't seem to have a logical justification. Patch 2 adds the TX lock and patch 3 associated test (which should hang with current net). Mallesham reports that even with these fixes applied the async accelerator workload still occasionally hangs waiting for socket memory. I suspect that's strictly related to the way async crypto is integrated in TLS, so I think we should get these into net or net-next and move from there. ==================== Signed-off-by: David S.

2019-11-06net/tls: add a TX lockJakub Kicinski4-14/+20
TLS TX needs to release and re-acquire the socket lock if send buffer fills up. TLS SW TX path currently depends on only allowing one thread to enter the function by the abuse of sk_write_pending. If another writer is already waiting for memory no new ones are allowed in. This has two problems: - writers don't wake other threads up when they leave the kernel; meaning that this scheme works for single extra thread (second application thread or delayed work) because memory becoming available will send a wake up request, but as Mallesham and Pooja report with larger number of threads it leads to threads being put to sleep indefinitely; - the delayed work does not get _scheduled_ but it may _run_ when other writers are present leading to crashes as writers don't expect state to change under their feet (same records get pushed and freed multiple times); it's hard to reliably bail from the work, however, because the mere presence of a writer does not guarantee that the writer will push pending records before exiting. Ensuring wakeups always happen will make the code basically open code a mutex. Just use a mutex. The TLS HW TX path does not have any locking (not even the sk_write_pending hack), yet it uses a per-socket sg_tx_data array to push records.

2019-11-06net/tls: don't pay attention to sk_write_pending when pushing partial recordsJakub Kicinski2-7/+6
sk_write_pending being not zero does not guarantee that partial record will be pushed. If the thread waiting for memory times out the pending record may get stuck. In case of tls_device there is no path where parial record is set and writer present in the first place. Partial record is set only in tls_push_sg() and tls_push_sg() will return an error immediately. All tls_device callers of tls_push_sg() will return (and not wait for memory) if it failed.

2019-11-06blkcg: make blkcg_print_stat() print stats only for online blkgsTejun Heo1-5/+8
blkcg_print_stat() iterates blkgs under RCU and doesn't test whether the blkg is online. This can call into pd_stat_fn() on a pd which is still being initialized leading to an oops. The heaviest operation - recursively summing up rwstat counters - is already done while holding the queue_lock. Expand queue_lock to cover the other operations and skip the blkg if it isn't online yet. The online state is protected by both blkcg and queue locks, so this guarantees that only online blkgs are processed.
