2022-07-26bridge: Do not send empty IFLA_AF_SPEC attributeBenjamin Poirier
After commit b6c02ef54913 ("bridge: Netlink interface fix."), br_fill_ifinfo() started to send an empty IFLA_AF_SPEC attribute when a bridge vlan dump is requested but an interface does not have any vlans configured. iproute2 ignores such an empty attribute since commit b262a9becbcb ("bridge: Fix output with empty vlan lists") but older iproute2 versions as well as other utilities have their output changed by the cited kernel commit, resulting in failed test cases. Regardless, emitting an empty attribute is pointless and inefficient. Avoid this change by canceling the attribute if no AF_SPEC data was added. Fixes: b6c02ef54913 ("bridge: Netlink interface fix.")

2022-07-25sctp: fix sleep in atomic context bug in timer handlersDuoming Zhou
There are sleep in atomic context bugs in timer handlers of sctp such as sctp_generate_t3_rtx_event(), sctp_generate_probe_event(), sctp_generate_t1_init_event(), sctp_generate_timeout_event(), sctp_generate_t3_rtx_event() and so on. The root cause is sctp_sched_prio_init_sid() with GFP_KERNEL parameter that may sleep could be called by different timer handlers which is in interrupt context. One of the call paths that could trigger bug is shown below: (interrupt context) sctp_generate_probe_event sctp_do_sm sctp_side_effects sctp_cmd_interpreter sctp_outq_teardown sctp_outq_init sctp_sched_set_sched n->init_sid(..,GFP_KERNEL) sctp_sched_prio_init_sid //may sleep This patch changes gfp_t parameter of init_sid in sctp_sched_set_sched() from GFP_KERNEL to GFP_ATOMIC in order to prevent sleep in atomic context bugs.

Due to an invalid conflict resolution on my side while working on 2 different series (LAG FDBs and FDB isolation), dsa_switch_do_lag_fdb_add() does not store the database associated with a dsa_mac_addr structure. So after adding an FDB entry associated with a LAG, dsa_mac_addr_find() fails to find it while deleting it, because &a->db is zeroized memory for all stored FDB entries of lag->fdbs, and dsa_switch_do_lag_fdb_del() returns -ENOENT rather than deleting the entry.

2022-07-26drm/amdgpu: Re-enable DCN for 64-bit powerpcMichael Ellerman
Commit d11219ad53dc ("amdgpu: disable powerpc support for the newer display engine") disabled the DCN driver for all of powerpc due to unresolved build failures with some compilers. Further digging shows that the build failures only occur with compilers that default to 64-bit long double. Both the ppc64 and ppc64le ABIs define long double to be 128-bits, but there are compilers in the wild that default to 64-bits. The compilers provided by the major distros (Fedora, Ubuntu) default to 128-bits and are not affected by the build failure. There is a compiler flag to force 128-bit long double, which may be the correct long term fix, but as an interim fix only allow building the DCN driver if long double is 128-bits by default. The bisection in commit d11219ad53dc must have gone off the rails at some point, the build failure occurs all the way back to the original commit that enabled DCN support on powerpc, at least with some toolchains.

2022-07-25intel_idle: Fix false positive RCU splats due to incorrect hardirqs stateWaiman Long
Commit 32d4fd5751ea ("cpuidle,intel_idle: Fix CPUIDLE_FLAG_IRQ_ENABLE") uses raw_local_irq_enable/local_irq_disable() around call to __intel_idle() in intel_idle_irq(). With interrupt enabled, timer tick interrupt can happen and a subsequently call to __do_softirq() may change the lockdep hardirqs state of a debug kernel back to 'on'. This will result in a mismatch between the cpu hardirqs state (off) and the lockdep hardirqs state (on) causing a number of false positive "WARNING: suspicious RCU usage" splats. Fix that by using local_irq_disable() to disable interrupt in intel_idle_irq().

When some error occurs after init_rx_sa() is called in macsec_add_rxsa(), the function released rx_sa with kfree() without releasing rx_sa->stats and rx_sa-> key.tfm, which will lead to a resource leak.

2022-07-25macsec: always read MACSEC_SA_ATTR_PN as a u64Sabrina Dubroca
Currently, MACSEC_SA_ATTR_PN is handled inconsistently, sometimes as a u32, sometimes forced into a u64 without checking the actual length of the attribute. Instead, we can use nla_get_u64 everywhere, which will read up to 64 bits into a u64, capped by the actual length of the attribute coming from userspace. This fixes several issues: - the check in validate_add_rxsa doesn't work with 32-bit attributes - the checks in validate_add_txsa and validate_upd_sa incorrectly reject X << 32 (with X != 0) Fixes: 48ef50fa866a ("macsec: Netlink support of XPN cipher suites (IEEE 802.1AEbw)") Signed-off-by: Sabrina Dubroca <sd@queasysnail.net> Signed-off-by: David S.

IEEE 802.1AEbw-2013 (section 10.7.8) specifies that the maximum value of the replay window is 2^30-1, to help with recovery of the upper bits of the PN. To avoid leaving the existing macsec device in an inconsistent state if this test fails during changelink, reuse the cleanup mechanism introduced for HW offload. This wasn't needed until now because macsec_changelink_common could not fail during changelink, as modifying the cipher suite was not allowed.

2022-07-24net/tls: Remove the context from the list in tls_device_downMaxim Mikityanskiy
tls_device_down takes a reference on all contexts it's going to move to the degraded state (software fallback). If sk_destruct runs afterwards, it can reduce the reference counter back to 1 and return early without destroying the context. Then tls_device_down will release the reference it took and call tls_device_free_ctx. However, the context will still stay in tls_device_down_list forever. The list will contain an item, memory for which is released, making a memory corruption possible. Fix the above bug by properly removing the context from all lists before any call to tls_device_free_ctx.

2022-07-23x86/speculation: Make all RETbleed mitigations 64-bit onlyBen Hutchings
The mitigations for RETBleed are currently ineffective on x86_32 since entry_32.S does not use the required macros. However, for an x86_32 target, the kconfig symbols for them are still enabled by default and /sys/devices/system/cpu/vulnerabilities/retbleed will wrongly report that mitigations are in place. Make all of these symbols depend on X86_64, and only enable RETHUNK by default on X86_64.

2022-07-22Revert "tcp: change pingpong threshold to 3"Wei Wang
This reverts commit 4a41f453bedfd5e9cd040bad509d9da49feb3e2c. This to-be-reverted commit was meant to apply a stricter rule for the stack to enter pingpong mode. However, the condition used to check for interactive session "before(tp->lsndtime, icsk->icsk_ack.lrcvtime)" is jiffy based and might be too coarse, which delays the stack entering pingpong mode. We revert this patch so that we no longer use the above condition to determine interactive session, and also reduce pingpong threshold to 1.
