2024-05-06selftests/bpf: Fix pointer arithmetic in test_xdp_do_redirectMichal Schmidt1-2/+2
Cast operation has a higher precedence than addition. The code here wants to zero the 2nd half of the 64-bit metadata, but due to a pointer arithmetic mistake, it writes the zero at offset 16 instead. Just adding parentheses around "data + 4" would fix this, but I think this will be slightly better readable with array syntax. I was unable to test this with tools/testing/selftests/bpf/vmtest.sh, because my glibc is newer than glibc in the provided VM image. So I just checked the difference in the compiled code. objdump -S tools/testing/selftests/bpf/xdp_do_redirect.test.o: - *((__u32 *)data) = 0x42; /* metadata test value */ + ((__u32 *)data)[0] = 0x42; /* metadata test value */ be7: 48 8d 85 30 fc ff ff lea -0x3d0(%rbp),%rax bee: c7 00 42 00 00 00 movl $0x42,(%rax) - *((__u32 *)data + 4) = 0; + ((__u32 *)data)[1] = 0; bf4: 48 8d 85 30 fc ff ff lea -0x3d0(%rbp),%rax - bfb: 48 83 c0 10 add $0x10,%rax + bfb: 48 83 c0 04 add $0x4,%rax bff: c7 00 00 00 00 00 movl $0x0,(%rax) Fixes: 5640b6d89434 ("selftests/bpf: fix "metadata marker" getting overwritten by the netstack") Signed-off-by: Michal Schmidt <[email protected]> Signed-off-by: Andrii Nakryiko <[email protected]> Reviewed-by: Toke Høiland-Jørgensen <[email protected]> Link: https://lore.kernel.org/bpf/[email protected]
2024-05-06selftests/bpf: Use bpf_tracing.h instead of bpf_tcp_helpers.hMartin KaFai Lau4-4/+5
The bpf programs that this patch changes require the BPF_PROG macro. The BPF_PROG macro is defined in the libbpf's bpf_tracing.h. Some tests include bpf_tcp_helpers.h which includes bpf_tracing.h. They don't need other things from bpf_tcp_helpers.h other than bpf_tracing.h. This patch simplifies it by directly including the bpf_tracing.h. The motivation of this unnecessary code churn is to retire the bpf_tcp_helpers.h by directly using vmlinux.h. Right now, the main usage of the bpf_tcp_helpers.h is the partial kernel socket definitions (e.g. socket, sock, tcp_sock). While the test cases continue to grow, fields are kept adding to those partial socket definitions (e.g. the recent bpf_cc_cubic.c test which tried to extend bpf_tcp_helpers.c but eventually used the vmlinux.h instead). The idea is to retire bpf_tcp_helpers.c and consistently use vmlinux.h for the tests that require the kernel sockets. This patch tackles the obvious tests that can directly use bpf_tracing.h instead of bpf_tcp_helpers.h.

2024-05-06Reapply "drm/qxl: simplify qxl_fence_wait"Linus Torvalds2-52/+5
This reverts commit 07ed11afb68d94eadd4ffc082b97c2331307c5ea. Stephen Rostedt reports: "I went to run my tests on my VMs and the tests hung on boot up. Unfortunately, the most I ever got out was: [ 93.607888] Testing event system initcall: OK [ 93.667730] Running tests on all trace events: [ 93.669757] Testing all events: OK [ 95.631064] ------------[ cut here ]------------ Timed out after 60 seconds" and further debugging points to a possible circular locking dependency between the console_owner locking and the worker pool locking. Reverting the commit allows Steve's VM to boot to completion again. [ This may obviously result in the "[TTM] Buffer eviction failed" messages again, which was the reason for that original revert. But at this point this seems preferable to a non-booting system... ] Reported-and-bisected-by: Steven Rostedt <[email protected]> Link: https://lore.kernel.org/all/[email protected]/ Acked-by: Maxime Ripard <[email protected]> Cc: Alex Constantino <[email protected]> Cc: Maxime Ripard <[email protected]> Cc: Timo Lindfors <[email protected]> Cc: Dave Airlie <[email protected]> Cc: Gerd Hoffmann <[email protected]> Cc: Maarten Lankhorst <[email protected]> Cc: Thomas Zimmermann <[email protected]> Cc: Daniel Vetter <[email protected]> Signed-off-by: Linus Torvalds <[email protected]>

Refactor struct ice_vsi_cfg_params to be embedded into struct ice_vsi. Prior to that the members of the struct were scattered around ice_vsi, and were copy-pasted for purposes of reinit.

2024-05-06wifi: iwlwifi: mvm: Fix race in scan completionIlan Peer4-29/+55
The move of the scan complete notification handling to the wiphy worker introduced a race between scan complete notification and scan abort: - The wiphy lock is held, e.g., for rfkill handling etc. - Scan complete notification is received but not handled yet. - Scan abort is triggered, and scan abort is sent to the FW. Once the scan abort command is sent successfully, the flow synchronously waits for the scan complete notification. However, as the scan complete notification was already received but not processed yet, this hangs for a second and continues leaving the scan status in an inconsistent state. - Once scan complete handling is started (when the wiphy lock is not held) since the scan status is not an inconsistent state, a warning is issued and the scan complete notification is not handled. To fix this issue, switch back the scan complete notification to be asynchronously handling, and only move the link selection logic to a worker (which was the original reason for the move to use wiphy lock). While at it, refactor some prints to improve debug data.

2024-05-06wifi: iwlwifi: mvm: Block EMLSR when a p2p/softAP vif is activeYedidya Benshimol7-19/+133
When there's an active link in a non-station vif, the station vif is not allowed to enter EMLSR Note that blocking EMLSR by calling iwl_mvm_block_esr() we will schedule an exit from EMLSR worker, but the worker cannot run before the activation of the non-BSS link, as ieee80211_remain_on_channel already holds the wiphy mutex. Handle that by explicitly calling ieee80211_set_active_links() to leave EMLSR, and then doing iwl_mvm_block_esr() only for consistency and to avoid re-entering it before ready. Note that a call to ieee80211_set_active_links requires to release the mvm mutex, but that's ok since we still hold the wiphy lock. The only thing that might race here is the ESR_MODE_NOTIF, so this changes its handler to run under the wiphy lock.

2024-05-06wifi: iwlwifi: mvm: exit EMLSR when CSA happensJohannes Berg5-26/+115
If CSA is happening, then exit EMLSR to keep the better link, which is the primary link unless that's doing the CSA with quiet. This is done because we can't transmit the OMN frame on a quiet link, but want to exit EMLSR during CSA for better beacon reception, so we can follow the switch accurately.

2024-05-06wifi: iwlwifi: mvm: avoid always prefering single-linkMiri Korenblit1-2/+2
The new link selection algorithm uses defaults values for BSS load if the BSS Load element was not published by the AP. For 6 GHz, that value is 0. So if the best link is 6 GHz, the EMLSR grade to always be equal to the grade of the best link, and then the best link grade is getting a bonus of 10 percent, meaning that we will never activate EMLSR. Change the logic to not give a bonus for the best link.
