Christoph Paasch reports [1] about incorrect skb->truesize after skb_expand_head() call in ip6_xmit. This may happen because of two reasons: - skb_set_owner_w() for newly cloned skb is called too early, before pskb_expand_head() where truesize is adjusted for (!skb-sk) case. - pskb_expand_head() does not adjust truesize in (skb->sk) case. In this case sk->sk_wmem_alloc should be adjusted too.

Vladimir Zapolskiy reports: Commit a7259df7 ("memblock: make memblock_find_in_range method private") invokes a kernel panic while running kmemleak on OF platforms with nomaped regions: Unable to handle kernel paging request at virtual address fff000021e00000 [...] scan_block+0x64/0x170 scan_gray_list+0xe8/0x17c kmemleak_scan+0x270/0x514 kmemleak_write+0x34c/0x4ac The memory allocated from memblock is registered with kmemleak, but if it is marked MEMBLOCK_NOMAP it won't have linear map entries so an attempt to scan such areas will fault. Ideally, memblock_mark_nomap() would inform kmemleak to ignore MEMBLOCK_NOMAP memory, but it can be called before kmemleak interfaces operating on physical addresses can use __va() conversion. Make sure that functions that mark allocated memory as MEMBLOCK_NOMAP take care of informing kmemleak to ignore such memory.

Merge branch 'ucount-fixes-for-v5.15' of git://git.kernel.org/pub/scm/linux/kernel/git/ebiederm/user-namespace Pull ucounts fixes from Eric Biederman: "There has been one very hard to track down bug in the ucount code that we have been tracking since roughly v5.14 was released. Alex managed to find a reliable reproducer a few days ago and then I was able to instrument the code and figure out what the issue was. It turns out the sigqueue_alloc single atomic operation optimization did not play nicely with ucounts multiple level rlimits. It turned out that either sigqueue_alloc or sigqueue_free could be operating on multiple levels and trigger the conditions for the optimization on more than one level at the same time. To deal with that situation I have introduced inc_rlimit_get_ucounts and dec_rlimit_put_ucounts that just focuses on the optimization and the rlimit and ucount changes. While looking into the big bug I found I couple of other little issues so I am including those fixes here as well. When I have time I would very much like to dig into process ownership of the shared signal queue and see if we could pick a single owner for the entire queue so that all of the rlimits can count to that owner. That should entirely remove the need to call get_ucounts and put_ucounts in sigqueue_alloc and sigqueue_free. It is difficult because Linux unlike POSIX supports setuid that works on a single thread" * 'ucount-fixes-for-v5.15' of git://git.kernel.org/pub/scm/linux/kernel/git/ebiederm/user-namespace: ucounts: Move get_ucounts from cred_alloc_blank to key_change_session_keyring ucounts: Proper error handling in set_cred_ucounts ucounts: Pair inc_rlimit_ucounts with dec_rlimit_ucoutns in commit_creds ucounts: Fix signal ucount refcounting

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().

The 1/10GbaseT modes were set up for cards with SFP+ cages in 3497ed8c ("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 5711a982 ("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).

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: f1267798 ("net/mlx5: Fix checksum issue of VXLAN and IPsec crypto offload") Signed-off-by:

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: f1267798 ("net/mlx5: Fix checksum issue of VXLAN and IPsec crypto offload") Signed-off-by:
