TLS is a relatively poor fit for strparser. We pause the input every time a message is received, wait for a read which will decrypt the message, start the parser, repeat. strparser is built to delineate the messages, wrap them in individual skbs and let them float off into the stack or a different socket. TLS wants the data pages and nothing else. There's no need for TLS to keep cloning (and occasionally skb_unclone()'ing) the TCP rx queue. This patch uses a pre-allocated skb and attaches the skbs from the TCP rx queue to it as frags. TLS is careful never to modify the input skb without CoW'ing / detaching it first. Since we call TCP rx queue cleanup directly we also get back the benefit of skb deferred free. Overall this results in a 6% gain in my benchmarks.

Wrap the remaining skb_cow_data() into a helper, so it's easier to replace down the lane. The new version will change the skb so make sure relevant pointers get reloaded after the call. Signed-off-by: Jakub Kicinski <kuba@kernel.org>

Expose TCP rx queue accessor and cleanup, so that TLS can decrypt directly from the TCP queue. The expectation is that the caller can access the skb returned from tcp_recv_skb() and up to inq bytes worth of data (some of which may be in ->next skbs) and then call tcp_read_done() when data has been consumed. The socket lock must be held continuously across those two operations. Signed-off-by: Jakub Kicinski <kuba@kernel.org>

The non-zero-copy path assumes a full skb with decrypted contents. This means the device offload would have to CoW the data. Try to keep the zero-copy status instead, copy the data to user space. Signed-off-by: Jakub Kicinski <kuba@kernel.org>

In the future we'll want to reuse the input skb in case of zero-copy so we shouldn't always free darg.skb. Move the freeing of darg.skb into the non-zc cases. All cases will now free ctx->recv_pkt (inside let tls_rx_rec_done()). Signed-off-by: Jakub Kicinski <kuba@kernel.org>

After recent changes the SW side of tls_rx_one_record() can be nicely encapsulated in its own function. Move the pad handling as well. This will be useful for ->zc handling in tls_decrypt_device(). Signed-off-by: Jakub Kicinski <kuba@kernel.org>

Jiri Pirko says: ==================== Implement dev info and dev flash for line cards This patchset implements two features: 1) "devlink dev info" is exposed for line card (patches 6-9) 2) "devlink dev flash" is implemented for line card gearbox flashing (patch 10) For every line card, "a nested" auxiliary device is created which allows to bind the features mentioned above (patch 4). The relationship between line card and its auxiliary dev devlink is carried over extra line card netlink attribute (patches 3 and 5). The first patch removes devlink_mutex from devlink_register/unregister() which eliminates possible deadlock during devlink reload command. The second patchset follows up with putting net pointer check into new helper. Examples: $ devlink lc show pci/0000:01:00.0 lc 1 pci/0000:01:00.0: lc 1 state active type 16x100G nested_devlink auxiliary/mlxsw_core.lc.0 supported_types: 16x100G $ devlink dev show auxiliary/mlxsw_core.lc.0 auxiliary/mlxsw_core.lc.0 $ devlink dev info auxiliary/mlxsw_core.lc.0 auxiliary/mlxsw_core.lc.0: versions: fixed: hw.revision 0 fw.psid MT_0000000749 running: ini.version 4 fw 19.2010.1312 $ devlink dev flash auxiliary/mlxsw_core.lc.0 file mellanox/fw-AGB-rel-19_2010_1312-022-EVB.mfa2 ==================== Link: https://lore.kernel.org/r/20220725082925.366455-1-jiri@resnulli.usSigned-off-by: Jakub Kicinski <kuba@kernel.org>

Remove dependency on devlink_mutex during devlinks xarray iteration. The reason is that devlink_register/unregister() functions taking devlink_mutex would deadlock during devlink reload operation of devlink instance which registers/unregisters nested devlink instances. The devlinks xarray consistency is ensured internally by xarray. There is a reference taken when working with devlink using devlink_try_get(). But there is no guarantee that devlink pointer picked during xarray iteration is not freed before devlink_try_get() is called. Make sure that devlink_try_get() works with valid pointer. Achieve it by: 1) Splitting devlink_put() so the completion is sent only after grace period. Completion unblocks the devlink_unregister() routine, which is followed-up by devlink_free() 2) During devlinks xa_array iteration, get devlink pointer from xa_array holding RCU read lock and taking reference using devlink_try_get() before unlock.

Christian Marangi says: ==================== Add MTU change with stmmac interface running This series is to permit MTU change while the interface is running. Major rework are needed to permit to allocate a new dma conf based on the new MTU before applying it. This is to make sure there is enough space to allocate all the DMA queue before releasing the stmmac driver. This was tested with a simple way to stress the network while the interface is running. 2 ssh connection to the device: - One generating simple traffic with while true; do free; done - The other making the mtu change with a delay of 1 second The connection is correctly stopped and recovered after the MTU is changed. The first 2 patch of this series are minor fixup that fix problems presented while testing this. One fix a problem when we renable a queue while we are generating a new dma conf. The other is a corner case that was notice while stressing the driver and turning down the interface while there was some traffic. (this is a follow-up of a simpler patch that wanted to add the same feature. It was suggested to first try to check if it was possible to apply the new configuration. Posting as RFC as it does major rework for the new concept of DMA conf) ==================== Link: https://lore.kernel.org/r/20220723142933.16030-1-ansuelsmth@gmail.comSigned-off-by: Jakub Kicinski <kuba@kernel.org>

Remove the limitation where the interface needs to be down to change MTU by releasing and opening the stmmac driver to set the new MTU. Also call the set_filter function to correctly init the port. This permits to remove the EBUSY error while the ethernet port is running permitting a correct MTU change if for example a DSA request a MTU change for a switch CPU port.
