2021-10-21io_uring: apply worker limits to previous usersPavel Begunkov1-0/+18
Another change to the API io-wq worker limitation API added in 5.15, apply the limit to all prior users that already registered a tctx. It may be confusing as it's now, in particular the change covers the following 2 cases: TASK1 | TASK2 _________________________________________________ ring = create() | | limit_iowq_workers() *not limited* | TASK1 | TASK2 _________________________________________________ ring = create() | | issue_requests() limit_iowq_workers() | | *not limited* A note on locking, it's safe to traverse ->tctx_list as we hold ->uring_lock, but do that after dropping sqd->lock to avoid possible problems. It's also safe to access tctx->io_wq there because tasks kill it only after removing themselves from tctx_list, see io_uring_cancel_generic() -> io_uring_clean_tctx() Signed-off-by: Pavel Begunkov <[email protected]> Link: https://lore.kernel.org/r/d6e09ecc3545e4dc56e43c906ee3d71b7ae21bed.1634818641.git.asml.silence@gmail.com Reviewed-by: Hao Xu <[email protected]> Signed-off-by: Jens Axboe <[email protected]>

Flush the destination page before invoking RECEIVE_UPDATE_DATA, as the PSP encrypts the data with the guest's key when writing to guest memory. If the target memory was not previously encrypted, the cache may contain dirty, unecrypted data that will persist on non-coherent systems.

2021-10-21net: enetc: make sure all traffic classes can send large framesVladimir Oltean1-1/+4
The enetc driver does not implement .ndo_change_mtu, instead it configures the MAC register field PTC{Traffic Class}MSDUR[MAXSDU] statically to a large value during probe time. The driver used to configure only the max SDU for traffic class 0, and that was fine while the driver could only use traffic class 0. But with the introduction of mqprio, sending a large frame into any other TC than 0 is broken. This patch fixes that by replicating per traffic class the static configuration done in enetc_configure_port_mac().

2021-10-21sfc: Export fibre-specific supported link modesErik Ekman1-11/+26
The 1/10GbaseT modes were set up for cards with SFP+ cages in 3497ed8c852a5 ("sfc: report supported link speeds on SFP connections"). 10GbaseT was likely used since no 10G fibre mode existed. The missing fibre modes for 1/10G were added to ethtool.h in 5711a9822144 ("net: ethtool: add support for 1000BaseX and missing 10G link modes") shortly thereafter. The user guide available at https://support-nic.xilinx.com/wp/drivers lists support for the following cable and transceiver types in section 2.9: - QSFP28 100G Direct Attach Cables - QSFP28 100G SR Optical Transceivers (with SR4 modules listed) - SFP28 25G Direct Attach Cables - SFP28 25G SR Optical Transceivers - QSFP+ 40G Direct Attach Cables - QSFP+ 40G Active Optical Cables - QSFP+ 40G SR4 Optical Transceivers - QSFP+ to SFP+ Breakout Direct Attach Cables - QSFP+ to SFP+ Breakout Active Optical Cables - SFP+ 10G Direct Attach Cables - SFP+ 10G SR Optical Transceivers - SFP+ 10G LR Optical Transceivers - SFP 1000BASE‐T Transceivers - 1G Optical Transceivers (From user guide issue 28. Issue 16 which also includes older cards like SFN5xxx/SFN6xxx has matching lists for 1/10/40G transceiver types.) Regarding SFP+ 10GBASE‐T transceivers the latest guide says: "Solarflare adapters do not support 10GBASE‐T transceiver modules." Tested using SFN5122F-R7 (with 2 SFP+ ports).

2021-10-21fuse: always initialize sb->s_fs_infoMiklos Szeredi1-25/+25
Syzkaller reports a null pointer dereference in fuse_test_super() that is caused by sb->s_fs_info being NULL. This is due to the fact that fuse_fill_super() is initializing s_fs_info, which is too late, it's already on the fs_supers list. The initialization needs to be done in sget_fc() with the sb_lock held. Move allocation of fuse_mount and fuse_conn from fuse_fill_super() into fuse_get_tree(). After this ->kill_sb() will always be called with non-NULL ->s_fs_info, hence fuse_mount_destroy() can drop the test for non-NULL "fm".

The ->put_super callback is called from generic_shutdown_super() in case of a fully initialized sb. This is called from kill_***_super(), which is called from ->kill_sb instances. Fuse uses ->put_super to destroy the fs specific fuse_mount and drop the reference to the fuse_conn, while it does the same on each error case during sb setup. This patch moves the destruction from fuse_put_super() to fuse_mount_destroy(), called at the end of all ->kill_sb instances. A follup patch will clean up the error paths.

Since commit c300ab9f08df ("KVM: x86: Replace late check_nested_events() hack with more precise fix") there is no longer the certainty that check_nested_events() tries to inject an external interrupt vmexit to L1 on every call to vcpu_enter_guest. Therefore, even in that case we need to set KVM_REQ_EVENT. This ensures that inject_pending_event() is called, and from there kvm_check_nested_events().

2021-10-20autofs: fix wait name hash calculation in autofs_wait()Ian Kent1-1/+1
There's a mistake in commit 2be7828c9fefc ("get rid of autofs_getpath()") that affects kernels from v5.13.0, basically missed because of me not fully testing the change for Al. The problem is that the hash calculation for the wait name qstr hasn't been updated to account for the change to use dentry_path_raw(). This prevents the correct matching an existing wait resulting in multiple notifications being sent to the daemon for the same mount which must not occur. The problem wasn't discovered earlier because it only occurs when multiple processes trigger a request for the same mount concurrently so it only shows up in more aggressive testing.

2021-10-20net/mlx5e: IPsec: Fix work queue entry ethernet segment checksum flagsEmeel Hakim1-9/+11
Current Work Queue Entry (WQE) checksum (csum) flags in the ethernet segment (eseg) in case of IPsec crypto offload datapath are not aligned with PRM/HW expectations. Currently the driver always sets the l3_inner_csum flag in case of IPsec because of the wrong usage of skb->encapsulation as indicator for inner IPsec header since skb->encapsulation is always ON for IPsec packets since IPsec itself is an encapsulation protocol. The above forced a failing attempts of calculating csum of non-existing segments (like in the IP|ESP|TCP packet case which does not have an l3_inner) which led to lots of packet drops hence the low throughput. Fix by using xo->inner_ipproto as indicator for inner IPsec header instead of skb->encapsulation in addition to setting the csum flags as following: * Tunnel Mode: * Pkt: MAC IP ESP IP L4 * CSUM: l3_cs | l3_inner_cs | l4_inner_cs * * Transport Mode: * Pkt: MAC IP ESP L4 * CSUM: l3_cs [ | l4_cs (checksum partial case)] * * Tunnel(VXLAN TCP/UDP) over Transport Mode * Pkt: MAC IP ESP UDP VXLAN IP L4 * CSUM: l3_cs | l3_inner_cs | l4_inner_cs Fixes: f1267798c980 ("net/mlx5: Fix checksum issue of VXLAN and IPsec crypto offload") Signed-off-by: Emeel Hakim <[email protected]> Signed-off-by: Saeed Mahameed <[email protected]>
2021-10-20net/mlx5e: IPsec: Fix a misuse of the software parser's fieldsEmeel Hakim1-24/+27
IPsec crypto offload current Software Parser (SWP) fields settings in the ethernet segment (eseg) are not aligned with PRM/HW expectations. Among others in case of IP|ESP|TCP packet, current driver sets the offsets for inner_l3 and inner_l4 although there is no inner l3/l4 headers relative to ESP header in such packets. SWP provides the offsets for HW ,so it can be used to find csum fields to offload the checksum, however these are not necessarily used by HW and are used as fallback in case HW fails to parse the packet, e.g when performing IPSec Transport Aware (IP | ESP | TCP) there is no need to add SW parse on inner packet. So in some cases packets csum was calculated correctly , whereas in other cases it failed. The later faced csum errors (caused by wrong packet length calculations) which led to lots of packet drops hence the low throughput. Fix by setting the SWP fields as expected in a IP|ESP|TCP packet. the following describe the expected SWP offsets: * Tunnel Mode: * SWP: OutL3 InL3 InL4 * Pkt: MAC IP ESP IP L4 * * Transport Mode: * SWP: OutL3 OutL4 * Pkt: MAC IP ESP L4 * * Tunnel(VXLAN TCP/UDP) over Transport Mode * SWP: OutL3 InL3 InL4 * Pkt: MAC IP ESP UDP VXLAN IP L4 Fixes: f1267798c980 ("net/mlx5: Fix checksum issue of VXLAN and IPsec crypto offload") Signed-off-by: Emeel Hakim <[email protected]> Reviewed-by: Raed Salem <[email protected]> Signed-off-by: Saeed Mahameed <[email protected]>
