The ndo_start_xmit() method must not attempt to free the skb to transmit when returning NETDEV_TX_BUSY. Therefore, make sure the korina_send_packet() function returns NETDEV_TX_OK when it frees a packet. Fixes: ef11291b ("Add support the Korina (IDT RC32434) Ethernet MAC") Suggested-by:

The parent of an ib device is used to retrieve the PCI device attributes. It turns out that there are possible cases when an ib device has no parent set in the device structure, which may lead to page faults when trying to access this memory. Fix that by checking the parent pointer and consolidate the pci device specific processing in a new function.

There are some use cases for netdev_notify_peers in the context when rtnl lock is already held. Introduce lockless version of netdev_notify_peers call to save the extra code to call call_netdevice_notifiers(NETDEV_NOTIFY_PEERS, dev); call_netdevice_notifiers(NETDEV_RESEND_IGMP, dev); After that, convert netdev_notify_peers to call the new helper.

This patch fixes an error condition triggered when the code path which transmits a S/G frame descriptor when the skb's headroom is not enough for DPAA2's needs. We are greated with a splat like the one below when a SGT structure is recycled and that is because even though a dma_unmap is performed on the Tx confirmation path, the unmap is not done with the proper size.

On the Rx side, the next_to_use index points to the next item in the HW ring to be refilled/allocated, and next_to_clean points to the next item to potentially be processed. When the HW Rx ring is fully refilled, i.e. no packets has been processed, the next_to_use will be next_to_clean - 1. When the ring is fully processed next_to_clean will be equal to next_to_use. The latter case is where a bug is triggered. If the next_to_use bits are not cleared, and the "fully processed" state is entered, a stale descriptor can be processed. The skb-path correctly clear the status bit for the next_to_use descriptor, but the AF_XDP zero-copy path did not do that. This change adds the status bits clearing of the next_to_use descriptor.

Even if there is more rx data waiting on the chip, the rx napi poll fn will never run more than once - it will always read a few buffers, then bail out and re-arm interrupts. Which results in ping-pong between napi and interrupt. This defeats the purpose of napi, and is bad for performance. Fix by making the rx napi poll behave identically to other ethernet drivers: 1. initialize rx napi polling with an arbitrary budget (64). 2. in the polling fn, return full weight if rx queue is not depleted, this tells the napi core to "keep polling". 3. update the rx tail ("ring the doorbell") once for every 8 processed rx ring buffers. Thanks to Jakub Kicinski, Eric Dumazet and Andrew Lunn for their expert opinions and suggestions.

In preparation to enable -Wimplicit-fallthrough for Clang, fix a couple of warnings by explicitly adding a break statement instead of just letting the code fall through to the next, and by adding a fallthrough pseudo-keyword in places where the code is intended to fall through.

Update the function to use sysfs_emit_at while neatening the uses of sprintf and overwriting the last space char with a newline to avoid possible output buffer overflow.

Kernel-doc markups should use this format: identifier - description Fix some issues on mm files: 1) The definition for get_user_pages_locked() doesn't follow it. Also, it expects a short descrpition at the header, followed by a long one, after the parameters. Fix it. 2) Kernel-doc requires that a kernel-doc markup to be immediately below the function prototype, as otherwise it will rename it. So, move get_pfnblock_flags_mask() description to the right place. 3) Make invalidate_mapping_pagevec() to also follow the expected kernel-doc format. While here, fix a few minor English syntax issues, as suggested by Matthew: will used -> will be used similar with -> similar to Link: https://lkml.kernel.org/r/80e85dddc92d333bc2159ee8a2294921612e8745.1605521731.git.mchehab+huawei@kernel.orgSigned-off-by:Mauro Carvalho Chehab <mchehab+huawei@kernel.org> Suggested-by: Mattew Wilcox <willy@infradead.org> [English fixes] Signed-off-by:

From the beginning, the zram block device always enabled CRYPTO_LZO, since lzo-rle is hardcoded as the fallback compression algorithm. As a consequence, on systems where another compression algorithm is chosen (e.g. CRYPTO_ZSTD), the lzo kernel module becomes unused, while still having to be built/loaded. This patch removes the hardcoded lzo-rle dependency and allows the user to select the default compression algorithm for zram at build time. The previous behaviour is kept, as the default algorithm is still lzo-rle. Link: https://lkml.kernel.org/r/20201207121245.50529-1-rsalvaterra@gmail.comSigned-off-by:
