2021-10-28octeontx2-af: Display all enabled PF VF rsrc_alloc entries.Rakesh Babu
Currently, we are using a fixed buffer size of length 2048 to display rsrc_alloc output. As a result a maximum of 2048 characters of rsrc_alloc output is displayed, which may lead sometimes to display only partial output. This patch fixes this dependency on max limit of buffer size and displays all PF VF entries. Each column of the debugfs entry "rsrc_alloc" uses a fixed width of 12 characters to print the list of LFs of each block for a PF/VF. If the length of list of LFs of a block exceeds this fixed width then the list gets truncated and displays only a part of the list. This patch fixes this by using the maximum possible length of list of LFs among all blocks of all PFs and VFs entries as the width size.

2021-10-28net/tls: Fix flipped sign in tls_err_abort() callsDaniel Jordan
sk->sk_err appears to expect a positive value, a convention that ktls doesn't always follow and that leads to memory corruption in other code. For instance, [kworker] tls_encrypt_done(..., err=<negative error from crypto request>) tls_err_abort(.., err) sk->sk_err = err; [task] splice_from_pipe_feed ... tls_sw_do_sendpage if (sk->sk_err) { ret = -sk->sk_err; // ret is positive splice_from_pipe_feed (continued) ret = actor(...) // ret is still positive and interpreted as bytes // written, resulting in underflow of buf->len and // sd->len, leading to huge buf->offset and bogus // addresses computed in later calls to actor() Fix all tls_err_abort() callers to pass a negative error code consistently and centralize the error-prone sign flip there, throwing in a warning to catch future misuse and uninlining the function so it really does only warn once.

2021-10-28net: ipconfig: Release the rtnl_lock while waiting for carrierMaxime Chevallier
While waiting for a carrier to come on one of the netdevices, some devices will require to take the rtnl lock at some point to fully initialize all parts of the link. That's the case for SFP, where the rtnl is taken when a module gets detected. This prevents mounting an NFS rootfs over an SFP link. This means that while ipconfig waits for carriers to be detected, no SFP modules can be detected in the meantime, it's only detected after ipconfig times out. This commit releases the rtnl_lock while waiting for the carrier to come up, and re-takes it to check the for the init device and carrier status.

2021-10-28mwifiex: fix division by zero in fw download pathJohan Hovold
Add the missing endpoint sanity checks to probe() to avoid division by zero in mwifiex_write_data_sync() in case a malicious device has broken descriptors (or when doing descriptor fuzz testing). Only add checks for the firmware-download boot stage, which require both command endpoints, for now. The driver looks like it will handle a missing endpoint during normal operation without oopsing, albeit not very gracefully as it will try to submit URBs to the default pipe and fail. Note that USB core will reject URBs submitted for endpoints with zero wMaxPacketSize but that drivers doing packet-size calculations still need to handle this (cf. commit 2548288b4fb0 ("USB: Fix: Don't skip endpoint descriptors with maxpacket=0")).

2021-10-28selftests/x86/amx: Add context switch testChang S. Bae
XSAVE state is thread-local. The kernel switches between thread state at context switch time. Generally, running a selftest for a while will naturally expose it to some context switching and and will test the XSAVE code. Instead of just hoping that the tests get context-switched at random times, force context-switches on purpose. Spawn off a few userspace threads and force context-switches between them. Ensure that the kernel correctly context switches each thread's unique AMX state. [ dhansen: bunches of cleanups ] Signed-off-by: Chang S.

2021-10-28selftests/x86/amx: Add test cases for AMX state managementChang S. Bae
AMX TILEDATA is a very large XSAVE feature. It could have caused nasty XSAVE buffer space waste in two places: * Signal stacks * Kernel task_struct->fpu buffers To avoid this waste, neither of these buffers have AMX state by default. The non-default features are called "dynamic" features. There is an arch_prctl(ARCH_REQ_XCOMP_PERM) which allows a task to declare that it wants to use AMX or other "dynamic" XSAVE features. This arch_prctl() ensures that sufficient sigaltstack space is available before it will succeed. It also expands the task_struct buffer. Functions of this test: * Test arch_prctl(ARCH_REQ_XCOMP_PERM). Ensure that it checks for proper sigaltstack sizing and that the sizing is enforced for future sigaltstack calls. * Ensure that ARCH_REQ_XCOMP_PERM is inherited across fork() * Ensure that TILEDATA use before the prctl() is fatal * Ensure that TILEDATA is cleared across fork() Note: Generally, compiler support is needed to do something with AMX. Instead, directly load AMX state from userspace with a plain XSAVE. Do not depend on the compiler. [ dhansen: bunches of cleanups ] Signed-off-by: Chang S.

With both memory latency (weight) and the new instruction latency information, users can easily locate the expensive load instructions, and also understand the time spent in different stages. The users can optimize their applications in different pipeline stages. Add a new field "ins_lat" to filter the instruction latency information, which is available with sample type PERF_SAMPLE_WEIGHT_STRUCT.

Commit cea0f76a483d ("dt-bindings: phy: Add DT bindings for Xilinx ZynqMP PSGTR PHY") clearly defines #phy-cells as 4. In past 5 cells were used by it never went to upstream. That's why fix example by using only 4 cells instead of 5.

Update the binding for ti-sysc interconnect target module driver to yaml format. Note that the old binding was never updated for the need to always specify also the generic compatible "ti,sysc".

The value of llc_testlink_time is set to the value stored in net->ipv4.sysctl_tcp_keepalive_time when linkgroup init. The value of sysctl_tcp_keepalive_time is already jiffies, so we don't need to multiply by HZ, which would cause smc_link->llc_testlink_time overflow, and test_link send flood.

2021-10-28nfp: bpf: relax prog rejection for mtu check through max_pkt_offsetYu Xiao
MTU change is refused whenever the value of new MTU is bigger than the max packet bytes that fits in NFP Cluster Target Memory (CTM). However, an eBPF program doesn't always need to access the whole packet data. The maximum direct packet access (DPA) offset has always been caculated by verifier and stored in the max_pkt_offset field of prog aux data.

This is not an issue by itself: HV_X64_MSR_REENLIGHTENMENT_CONTROL is a partition-wide MSR and it doesn't matter which particular CPU will be used to receive reenlightenment notifications. The only real problem can (in theory) be observed if the CPU whose id was acquired with smp_processor_id() goes offline before we manage to write to the MSR, the logic in hv_cpu_die() won't be able to reassign it correctly.

2021-10-28RDMA/rxe: Use 'bitmap_zalloc()' when applicableChristophe JAILLET
'index.table' is a bitmap. So use 'bitmap_zalloc()' to simplify code, improve the semantic and avoid some open-coded arithmetic in allocator arguments. Using 'bitmap_zalloc()' also allows the removal of a now useless 'bitmap_zero()'. Also change the corresponding 'kfree()' into 'bitmap_free()' to keep consistency.
