2021-12-24crypto: qat - set COMPRESSION capability for QAT GEN2Giovanni Cabiddu
Enhance the device capability detection for QAT GEN2 devices to detect if a device supports the compression service. This is done by checking both the fuse and the strap registers for c62x and c3xxx and only the fuse register for dh895xcc.

Rather than passing all variables as modified, pass ones that are only read into that parameter. This helps with old gcc versions when alternatives are additionally used, and lets gcc's codegen be a little bit more efficient. This also syncs up with the latest Vale/EverCrypt output.

2021-12-23ext4: use ext4_journal_start/stop for fast commit transactionsHarshad Shirwadkar
This patch drops all calls to ext4_fc_start_update() and ext4_fc_stop_update(). To ensure that there are no ongoing journal updates during fast commit, we also make jbd2_fc_begin_commit() lock journal for updates. This way we don't have to maintain two different transaction start stop APIs for fast commit and full commit. This patch doesn't remove the functions altogether since in future we want to have inode level locking for fast commits.

2021-12-23drm/etnaviv: consider completed fence seqno in hang checkLucas Stach
Some GPU heavy test programs manage to trigger the hangcheck quite often. If there are no other GPU users in the system and the test program exhibits a very regular structure in the commandstreams that are being submitted, we can end up with two distinct submits managing to trigger the hangcheck with the FE in a very similar address range. This leads the hangcheck to believe that the GPU is stuck, while in reality the GPU is already busy working on a different job. To avoid those spurious GPU resets, also remember and consider the last completed fence seqno in the hang check.

2021-12-23r8152: sync ocp baseHayes Wang
There are some chances that the actual base of hardware is different from the value recorded by driver, so we have to reset the variable of ocp_base to sync it. Set ocp_base to -1. Then, it would be updated and the new base would be set to the hardware next time. Signed-off-by: Hayes Wang <hayeswang@realtek.com> Signed-off-by: Jakub Kicinski <kuba@kernel.org>

It needs to set mdio force mode. Otherwise, link off always occurs when setting force speed. Fixes: 195aae321c82 ("r8152: support new chips") Signed-off-by: Hayes Wang <hayeswang@realtek.com> Signed-off-by: Jakub Kicinski <kuba@kernel.org>

2021-12-23net: bridge: fix ioctl old_deviceless bridge argumentRemi Pommarel
Commit 561d8352818f ("bridge: use ndo_siocdevprivate") changed the source and destination arguments of copy_{to,from}_user in bridge's old_deviceless() from args[1] to uarg breaking SIOC{G,S}IFBR ioctls. Commit cbd7ad29a507 ("net: bridge: fix ioctl old_deviceless bridge argument") fixed only BRCTL_{ADD,DEL}_BRIDGES commands leaving BRCTL_GET_BRIDGES one untouched. The fixes BRCTL_GET_BRIDGES as well and has been tested with busybox's brctl. Example of broken brctl: $ brctl show bridge name bridge id STP enabled interfaces brctl: can't get bridge name for index 0: No such device or address Example of fixed brctl: $ brctl show bridge name bridge id STP enabled interfaces br0 8000.000000000000 no Fixes: 561d8352818f ("bridge: use ndo_siocdevprivate") Signed-off-by: Remi Pommarel <repk@triplefau.lt> Reviewed-by: Arnd Bergmann <arnd@arndb.de> Acked-by: Nikolay Aleksandrov <nikolay@nvidia.com> Link: https://lore.kernel.org/all/20211223153139.7661-2-repk@triplefau.lt/ Signed-off-by: Jakub Kicinski <kuba@kernel.org>

2021-12-23net: dsa: tag_ocelot: use traffic class to map priority on injected headerXiaoliang Yang
For Ocelot switches, the CPU injected frames have an injection header where it can specify the QoS class of the packet and the DSA tag, now it uses the SKB priority to set that. If a traffic class to priority mapping is configured on the netdevice (with mqprio for example ...), it won't be considered for CPU injected headers. This patch make the QoS class aligned to the priority to traffic class mapping if it exists.

2021-12-23veth: ensure skb entering GRO are not cloned.Paolo Abeni
After commit d3256efd8e8b ("veth: allow enabling NAPI even without XDP"), if GRO is enabled on a veth device and TSO is disabled on the peer device, TCP skbs will go through the NAPI callback. If there is no XDP program attached, the veth code does not perform any share check, and shared/cloned skbs could enter the GRO engine. Ignat reported a BUG triggered later-on due to the above condition: [ 53.970529][ C1] kernel BUG at net/core/skbuff.c:3574!
